A robot includes a gripping section and a main body section to which the pair of finger sections are attached, having one end sections of the pair of finger sections rotatably connected to each other around a first rotating shaft disposed at a position separate from the main body section, and adapted to open and close the pair of finger sections by swinging the other side of the pair of finger sections on a plane parallel to a mounting surface on which an object is mounted centered on the first rotating shaft to thereby grip the object, a moving device adapted to relatively move the object and the gripping section, and a control device adapted to control the moving device to move the gripping section relatively toward the object, and grip the object with the gripping section at at least three contact points.

A toggle press is provided with two levers (14, 16) which are pivotably connected by means of a joint (18), the first of which (14) is connected at its free end to a pressing tool (22) and the second of which (16) is rotation-resistantly mounted at its free end on a shaft (28) which can be rotated by a drive unit. The rotation-resistant connection between the second lever (16) and shaft (28) is releasable when the toggle lever reaches the extended position. The second lever (16) is disposed on a section of shaft (28) contrived as an eccentric cam (44).

A side-by-side robot workcell includes two tables each of which is movable from a work position to a load position. Linkages are connected to the tables and cause the tables to have a slow speed at the time the tables approach either the load or the work position, and a faster speed in the middle of the movement between the work and load positions.

A transfer device includes a transfer tool which is activated by a rectilinear guide, i.e. by a mechanism made such that a point of attachment of the transfer tool describes a rectilinear trajectory when the guide is activated. A drive element for activating the guide is provided with non-rectilinear motion, and in particular with angular motion. Preferably, the rectilinear guide consists of an articulated oscillating linkage. The transfer device is used in a packaging machine for cigarettes or the like, in which, whenever possible, for each transfer of product into the processing path of the machine, rectilinear transfer units for the products are used, which transfer units are actuated by transfer devices activated by articulated oscillating linkages.

A water saving device, implemented as a pair of spring loaded, normally-open shutoff valves inserted into the hot and cold water supply lines of a faucet, which are connected via a cable mechanism to a foot actuator. Actuating the mechanism causes the shutoff valves to close, interrupting any flow of water in the supply lines. Releasing the mechanism allows flow to resume. The shutoff valves are installed in series upstream of the normal hand-operated faucet valves. The user starts the water flow and adjusts the temperature of the water in the normal manner using the hand-operated faucet valves. When the user wishes to temporarily stop the water flow he or she steps on the foot pedal, thereby causing the shutoff valves to close. When the pedal is released the shutoff valves open and the water flow resumes at the same flow rate and temperature previously set by the user.

A sliding load for calibrating a microwave network analyzer provides an alignment of its center conductor relative to a reference plane defined by its outer conductor. The sliding load includes a latching assembly which in an unlatched condition allows the center conductor to move freely in an axial direction relative to the outer conductor. The center conductor can then project forward of the outer conductor for visual alignment with a mating center conductor of a network analyzer connector. Once the center conductors are mated, the outer conductor of the sliding load and the connector can be butted at the reference plane. The latching assembly can then be rotated into its latched condition in which a spring is compressed. The compressed spring forces the center conductor to retract against a screw stop. The screw stop is adjusted so that when the center conductor is forced against it, the desired alignment of the center conductor and the reference plate is achieved. As a result of this alignment, the sliding load does not obscure or exaggerate the contribution of network analyzer connector setback to changes in signals transmitted by the network analyzer. Thus, the network analyzer can be more accurately characterized and calibrated so that it, in turn, can characterize devices under test more precisely.

Wherever large forces have to be applied over short distances it is useful to employ a force multiplier device. Very large transmission ratios are, according to the present invention, obtained by interruption of the axis of rotation (2) and insertion of an only slightly displaced force transmission axis (4). The force transmission axis (4) can be continuously displaced to both sides of the axis of rotation (2) by means of positioning facilities, preferable an adjusting screw (5) or two wedges. This way variable force generation is obtained with a widely variable range of transmission ratio.The invention can be employed e.g. for the manufacture and operation of presses, clamping, bending and tension devices.

A low-to-high pressure, fusion-welding, press mechanism for vertical packing machines which seals packed products using packing film. The press mechanism comprises a cylinder, a cylinder rod, a circular disc, a plurality of pairs of levers and a pair of sealing substrates having a pair of sealing blades, these members being interconnected to each other to fusion-weld packed products with said pair of sealing blades under desired sealing pressure.

A vehicle has container handling apparatus at each end. This apparatus has a pedestal with track arms which with the pedestal form a lateral trackway on which a carriage can run, for lifting, traversing and lowering a container. Each track arm in the operative position is supported by an over-center toggle-jointed arm. The toggle arms are moved by relatively small and relatively low pressure hydraulic rams. In the over-center position of the arms each is locked by a short shaft mounted by the lower toggle joint and engaging with an edge of the upper toggle joint.
