Method and apparatus for optically testing the quality of objects such as silicon wafers which have a circular peripheral edge, wherein light is directed onto the edge region of the object, and the light radiating from the object due to reflection, refraction and/or diffraction is detected by means of a measuring unit which produces an image from the received light. Defects on and/or in the object are identified from the produced image.

A retractable awning includes a roller reversibly driven and mounted within a housing for support on a support structure and both inner and outer sets of pivotally interconnected support arms for supporting an awning canopy when extended. The inner set of support arms support the canopy beneath an inner segment of the canopy adjacent the support surface and are designed to deploy before the outer set of support arms with the outer set of support arms supporting the canopy beneath an outer segment of the canopy further away from the support surface than the inner segment. Both the inner and outer sets of support arms can be partially or fully deployed to regulate the extent to which the awning is extendible away from the support surface. The outer support arms are mounted for pivotal movement within a plane forming a different angle with horizontal than the inner set of support arms so the inner segment of the canopy above the inner set of support arms when extended forms a different angle with horizontal than does the outer segment of the awning canopy overlying the outer set of support arms when extended.

This invention detects the crank angle location where combustion switches from premixed to diffusion, referred to as the transition index, and uses that location to define integration limits that measure the portions of heat released during the combustion process that occur during the premixed and diffusion phases. Those integrated premixed and diffusion values are used to develop a metric referred to as the combustion index. The combustion index is defined as the integrated diffusion contribution divided by the integrated premixed contribution. As the EGR rate is increased enough to enter the low temperature combustion regime, PM emissions decrease because more of the combustion process is occurring over the premixed portion of the heat release rate profile and the diffusion portion has been significantly reduced. This information is used to detect when the engine is or is not operating in a low temperature combustion mode and provides that feedback to an engine control algorithm.

An outsole for a shoe has a bottom surface with a fabric insert glued into a recess. The method of gluing the fabric insert to the shoe outsole comprises cleaning the recess of the outsole, priming the recess to receive glue, applying glue to the recess; applying glue to the fabric insert; and pressing the fabric insert into the recess to fix the fabric insert in the recess.

The present invention relates to capsules for encapsulating functional agents, such as flavors, fragrances, pharmaceuticals, vitamins, etc. The capsules are suitable for the encapsulation of hydrophobic as well as hydrophilic substances. The capsules include a micro-organism, a matrix component and the encapsulatable material, wherein the latter comprises the functional agent or agents. The invention further relates to a process for manufacturing the capsules and to food products containing the capsules.

An apparatus and a process for crystallizing substances from solutions or dispersions containing these substances, in a crystallizer containing a classifying zone (3), comprise a) an inner and an outer circulation system (1; 2), the inner circulation system (1) being present in the crystallizer, the inlet of the outer circulation system (2) being connected to the inner circulation system (1) via the classifying zone (3), the outer circulation system, being present outside the crystallizer, the outlet of the outer circulation system (2) being connected to the inner circulation system (1) of the crystallizer, and a means for dissolving crystals being arranged in the outer circulation system (2), before its outlet, b) an inflow (4) for solution and/or dispersion, which inflow is present on the crystallizer or on the outer circulation system, and c) an outflow (5) for dispersions, which outflow is arranged on the crystallizer or on the outer circulation system. The novel apparatus has the special feature that a line (8) connecting the outer and inner circulation systems (1; 2) to one another and intended for transporting (recycling) dispersion and/or a line (8) for transporting (recycling) dispersion are additionally present, in which both its entrance and its exit are connected to the inner circulation system (1).

An attachment gusset with ruffled corners and method and machinery for manufacture provides a gusset formed of a continuous strip of material which is pleated at corners or turns in direction of the gusset to form ruffles which are attached to an adjacent layer of material. The ruffled gusset lies substantially flat against adjacent layers of material to which it is attached in a pressed state, and can be expanded to accommodate dimensional structures, such as cushioned pads. The number and spacing of pleats can be adjusted according to the radius of the corners or turns in the gusset. In a method of construction of the gusset, the pleats are formed as the material to which the gusset is attached is turned relative to the sewing point of attachment.

An electronic device (100) has a heatsink (116) and electrical contacts (120) which are originally all part of a support frame (200). After assembly, the border of the support frame (202) is broken off, thereby electrically isolating the electrical contacts (120) from one another, and from the heatsink (116). The electrical contacts (120) and the heatsink (116) are coplanar. In one version, the electrical contacts (120) do not extend past the circuit board (102) of the device (100).

A method for selectively controlling the plating thickness on opposing sides of a body is disclosed. The method comprises providing an assembly of the body to be plated, a shield having apertures therein and a sealing member between body to be plated and the shield. The sealing member has an opening to allow plating solution to reach one surface of the body to be plated and has further openings to allow gases and depleted solution to escape from the assembly. The process provides a thinner layer of plated metal on the inner surface of the body to be plated and a thicker layer in the outer surface. It is particularly useful in plating ceramic circuit boards.

A retractable motor-driven awning can be extended or retracted by energizing the motor in one direction or another. A manually operable system, however, is also employed for rotating the awning by hand in a direction to retract the awning in the event the motor drive becomes inoperable. The ability to hand rotate the roll bar to retract the awning is achieved by connecting the roll bar to the drive shaft of the motor with a manual override system. Implementations of a manual override mechanism include one-way bearings and various ratchet designs.
