Abstract: ABSTRACT              A fluid dispenser for mounting in a door of an appliance such as an automatic dishwasher and having an elongated valve member with upper and lower spaced seal cambers and disposed in a cylindrical metering chamber located immediately adjacent a fluid reservoir. A fluid passageway connects the metering  chamber with the fluid reservoir enabling a deflector member to transfer a quan-tity of fluid into the metering chamber. A flexible bi-metal element with one end attached to the upper end of the valve member spring biases the valve member toward a posi-tion sealing the metering chamber.  Upward deflection of the bimetal element by electrical heating lifts the valve member to an open position permitting a precise quantity of fluid to freely discharge by gravity feed  from the metering chamber while permitting atmospheric air to enter through the upper valve seat. A fluted fill plug mounted in an open-ing transversely aligned to the metering chamber allows the fluid discharged from the metering chamber to flow along the fluid to a dispensed location exteriorly of the dispenser, and also shields the lower valve seat from contaminants. The plug is translucent and provides an optical indication of the supply in the fluid reservoir.

Abstract: ABSTRACT OF THE DISCLOSURE       An arrangement for oscillating a rotating dishwasher spray arm about its longitudinal axis to direct the jet sprays at the dishware items at various differing angles including forward, reverse and vertical inclinations to increase cover-age and to improve the jet spray washing action by reducing shadowing.  The oscillation is produced by a drive gear and crank mechanism driven by a fixed reaction gear as the spray arm rotates.  Jet reaction forces are utilized to rotate the spray arm and are related with respect to the axis of rotation of the spray arm so that the resultant torque causing rota-tion of the spray arm does not significantly vary as the spray arm is oscillated to insure the proper rotational speed of the spray arm.  The frequency of oscillation relative to the frequency of rotation is selected to be such that a num-ber of differing jet spray angles are produced for each rota-tional position of the spray arm in successive revolutions thereof to minimize shadowing effects.  Particular mounting details for the spray arm accommodate the simultaneous rota-tion and oscillation and allow the supply of washing liquid via the mounting structure.

Abstract: METHOD FOR FORMING SEMICONDUCTOR CONTACTS          Abstract A method for selectively depositing contacts in semiconductor regions.  One set of contact openings is protected by a barrier layer during the metal-lization of another set of exposed contact openings to improve the cleanliness and reliability of the contacts.  The barrier layer is then removed and a second layer of metallization is deposited in both sets of openings.  In the preferred embodi-ment a standard diffusion mask is used to define all contact regions and a screen oxide is thermally grown in each of the contact openings. A blocking photoresist mask is then applied and patterned to expose the oxide in those openings in which a first set of contacts is to be formed.  The screen oxide is removed and the first layer of metallization, typically platinum silicide, is then formed.  The screen oxide is then removed from the protected contact areas and the second layer of metallization, for example, chrome, aluminum, or other metals or combinations thereof are deposited in all openings, thereby forming one layer of metallurgy in the second set of openings and two layers in the first set.

Abstract: Improvements in or relating to Visual Display Apparatus Abstract The invention provides head-coupled area-of-interest visual display apparatus particularly for ground-based craft-flight simulators.  An image generator of the computer generated image type is used.  Line scanning apparatus is cockpit-mounted;  transmission of line image is by fibre optic guide ribbon and frame scan apparatus is helmet-mounted.  Sensing means detect head/helmet movement to permit voluntary scanning of a wide angle of simulated view from the craft.  Due to the projection mount having the capability of continuous rotation, with the image being computed for discrete angular positions only, together with the computational throughput delay in the image computer, the new image, after head/helmet rotation, is momentarily delayed after the new line of vision is established.  Means are provided to de-rotate the projected image to its former position on the screen until such time as the modified image is available.     P.2097/1

Abstract: Abstract of the Disclosure Our invention comprises an applicator roller positioned closely adjacent but not touching a photoconductive surface on which there is a latent electrostatic image to be developed.  The surface of the latent image and the surface of the applicator move at synchronous speed and are spaced from each other.  The applicator roller is adapted to be wetted with an electrophoretic type of developer liquid.  The volume of developer liquid on the roller surface is controlled to within narrow limits.  The developer liquid carries charged toner particles enabling the developer liquid to jump the gap between the applicator roller and the latent electrostatic image on the photoconductive surface.  Our method and apparatus is such that substantially only the latent electrostatic image is moistened by developer liquid.  The control of the volume of developer liquid on the applicator roller may be accom-plished by providing the surface of the applicator roller with re-entrant portions of predetermined capacity.  This volume may also be controlled by using a smooth-surfaced applicator roller together with a closely-adjacent but spaced reverse doctor roller adapted to meter the thickness of the film on the smooth applicator roller.  Post-transfer electro-phoresis is aided either by a field electrode biased to a potential of the same polarity as the polarity of the latent electrostatic field or by a corona discharge device biased to a potential opposite to that of the latent electrostatic field of the developed image.  Owing to the fact that the developer liquid has a lower vapor pressure than the liquid component of liquid developers of the prior art and a higher ratio of toner particles to carrier liquid than the developing liquids of the prior art, substantially no evaporation of the carrier liquid occurs with our method and apparatus and our copies, when transferred to a carrier sheet, are substantially dry.

Abstract: Abstract of the Invention In a tack seat lasting machine the wipers are moved lengthwise of the shoe and inwardly thereof under the action of a single piston-and-cylinder arrangement. For setting the appropriate "nail pattern", the action of said piston-and-cylinder arrangement is terminated by adjustable stroke limiting means, comprising a valve actuated by an abutment, the valve moving with the wipers and the abutment being adjustably positioned in the path of the valve. A further abutment, spaced from the first-mentioned abutment, controls the rest position of the wipers. The wipers are arranged symmetrically centrally of the machine, and the heel band is capable of clamping a shoe in the position in which it is presented by the operator, thereby avoiding the need to adjust the wipers for lefts and rights.

Abstract: ABSTRACT         Food products such as produce, fish, meat and poultry are rapidly cooked and chilled in separate units through which a continuously running conveyor belt passes in a spiral pathway to conserve cabinet space and produce energy efficient operation.  Water is used as the heating and chilling medium in 100% humidity steam and cold humid air atmospheres respectively preferably at a pressure above atmospheric.  This keeps all equipment surfaces moist and not readily contaminated by dried, accumulated, burnt on drippings, fat, proteins or other food residues.  Thus, the sanitization process is simplified. The system operates with the conveyor belt continuously running in both food processing and mechanical sanitizing modes.  The latter mode includes continuous cleaning of the belt and a periodic sanitation cycle with the food processing system shut down.  The sanitization is achieved by jet spray scrubbing with warm water and detergent solution and circulation through the system. Spiral belt paths of both chiller and cooker units are scanned by a rotary jet spray within the spiral. Sanitization of the entire system simultaneously prevents any re-contamination of one section by residue from another and saves time, cleaning liquids and energy.
