A lock assembly includes a single switch actuated by a cam for monitoring the position of a main bolt and an auxiliary bolt. The main bolt and the auxiliary bolt engage and move the cam between an actuated position and a released position. In the actuated position the cam actuates a switch. Actuation of the switch indicates that the auxiliary bolt is retracted and that the main bolt is extended into a locked position. The main bolt includes a tail that engages a portion of the cam to drive the cam to the actuated position. The switch will remain in the actuated condition when the auxiliary bolt is retracted and the main bolt is also retracted.

An electronic lock assembly is actuated by a key including a transponder. The key is received within a coil assembly of the lock assembly. The key engages a switch that powers the coil assembly. The coil assembly generates a magnetic field that energizes the transponder. The transponder transmits a signal received by a controller. The controller actuates the lock assembly responsive to the received signal to move a locking member to an unlocked position. The key may then move to unlatch a latch associated with the lock assembly. As the key provides the energy required for unlatching the latch further energization of the motor is not required. The lock assembly provides for the actuation and energization of the transponder with small amounts electrical energy such that the lock assembly may be powered by commercially available batteries for a practical operational life.

A combination lock includes various features that make the lock manipulation-resistant. The lock has a rocker arm with a curved underside section that contacts a roller on a cam that rotates when the lock dial is rotated. The smooth curve and an angled contact portion on the rocker arm causes the force applied to the rocker arm by the roller to be gradual rather than abrupt, ensuring that the contact point between the rocker arm and the roller is unpredictable. The lock may also include various spring-biased relocking devices that are biased away from the travel path of the bolt when the back cover is attached to the housing. The biasing force in the relocking device causes the device to move into the travel path of the bolt when the back cover is displaced or removed, preventing the bolt from moving to an unlocked position. The lock may also include a toothed washer having a trapezoidal tooth and a corresponding trapezoidal notch in a tube in the lock housing to eliminate transfer of rotation from one wheel to another. The trapezoidal shapes eliminate air gaps between the tooth and the notch, tightening the dial span of the lock.

A locking system for a stop button employed in a mortise lock having a spindle for operating a latch utilizing a first spindle base and a second spindle base which are nested relative to one another. Each base includes an opening for the mortise lock spindle such that the spindle may enter the combined first and second bases from the left side or the right side. A locking hub overrides either the first or second base and is capable of selectively lying over either the first or second base. An abutment linked to the stop button interacts with the locking hub such that either the first or second base may not be turned by the spindle when this occurs. Locking hub selectively locks either the first or second base through its position relative to the same and allows the mortise lock to easily transform from a left-hand version to a right-hand version.

An electronic lock includes a compression spring that stores energy to ensure that the electronic lock re-locked after unlocking. The spring is received between a lock bolt and a lock bolt housing. When the electronic lock is locked, the lock bolt is received in a notch of a locking portion. When the electronic lock is unlocked, a motor moves both the lock bolt and the lock bolt housing in a direction to remove the lock bolt from the notch. After a predetermined amount of time, the motor is reversed to move the lock bolt housing in an opposing direction. If the outside handle has not been released, the lock bolt does not re-enter the notch. The spring is compressed between the lock bolt housing and the lock bolt and stores energy. When the outside handle is released and the notch returns to the original position, and the spring pushes the lock bolt into the notch to ensure the electronic lock is re-locked.

A receptacle venting and freshening device for facilitating removal of liners from trash cans includes a tube, which has a first surface that is complementary to a face of a receptacle. A top of the tube is positioned proximate to an upper end of the receptacle and a bottom of the tube rests on a lower end of the receptacle. A plurality of fasteners is coupled to the first surface and is configured to couple the tube to the receptacle. A hanger, coupled to an interior surface of the tube proximate to the top, is configured to retain an air freshener unit. A plurality of cutouts, positioned in the tube proximate to the bottom, is configured to allow air to flow over the air freshener unit to exit from the tube through the cutouts as a liner positioned in the receptacle is withdrawn from the receptacle to freshen the receptacle.

A method is provided in one example embodiment and includes receiving at a network element having a binding table a packet that is part of a flow, the binding table having an entry corresponding to the flow, the entry mapping the flow to a first one of a plurality of endpoints and recognizing that a state of the first one of the plurality of endpoints at the first network element is not active. The method further includes, determining that the state of the first one of the plurality of endpoints at a second network element mated with the first network element and having a binding table similar to the binding table of the first network element is active. The method still further includes, directing the flow to the first one of the plurality of endpoints via the second network element.

The invention refers to a vehicular fluid heater (3), in particular to an automotive water heater. The vehicular fluid heater (3) comprises at least one heat exchanger (8) and at least one electrically operated heating unit (9), the heat exchanger (8) comprising at least one thermally conductive body defining at least one fluid channel for the fluid to be heated and sealing covers (16a, 16b) sealing the front and rear ends of the thermally conductive body, at least one cover (16a) having an inlet and/or outlet for establishing fluid flow, the heating unit (9) being joint to a heat-conductive surface of the thermally conductive body. The sealing covers (16a, 16b) are made from a pressure deformable material and are held in position by a housing and closing the fluid heater (FIG. 3).

The present invention relates to geopolymer compositions, methods of producing the compositions, and uses thereof. The geopolymer compositions broadly are comprised of a geopolymer binder and an aggregate and, once cured, can exhibit compressive strengths in excess of that of Portland cement-based concrete formulations. The geopolymer composition of the present invention adheres to most surfaces and can b used in the formation of a mortarless building block, floor screed, bench, building block brick, support column or pre-molded column, beam, paving stone, tiles, stone accouterment for a garden, countertop, bathtub, sink, a geopolymer slab, a structural geopolymer composition, a reinforced geopolymer composition, a steel reinforced geopolymer composition, or as a substitute for structural concrete in foundations, beams, columns, or slab with the addition as necessary of steel reinforcement.

The invention provides a method for the preparation of a foamed drink comprising the steps of: providing a capsule containing a foamable ingredient; providing a receptacle positioned to collect fluid escaping from the capsule; injecting liquid into the capsule to mix with the foamable ingredient; allowing the foamable ingredient mixed with the liquid to escape from the capsule into the receptacle; followed by injecting further liquid into the receptacle in a jet having a diameter of from about 0.5 to about 2 mm to produce foamed liquid in the receptacle. The invention also provides capsules, apparatus and systems specifically adapted for use in the method. Preferably, the food ingredient is a milk powder, and the method produces a hot foamed beverage such as a cappuccino coffee.
