Abstract: ABSTRACT OF THE DISCLOSURE   A process for recording laser radiation is disclosed.  A photosensi-tive material comprising a copying coating and a carrier is exposed to a visible light having no ultra-violet component and is then developed.  The process is characterized by the use of a negative working diazonium compound and a colorant which absorbs light in the spectral range between 450 and 550 nm and which sensitizes the diazonium co compound for exposure to laser light.  The use of this colorant increases the sensitivity of the diazonium compound to radiation outside of the known sensitivity of the diazonium.

Abstract: ABSTRACT OF THE DISCLOSURE           An upright vacuum cleaner having a suction nozzle at the front of the bottom of the chassis is provided with a nozzle height adjusting mechanism for varying the elevation of the rear wheels relative to the chassis to provide a multiplicity of nozzle height positions.  The rear axle is journaled on the chassis and includes a pair of off-set legs on which a respective rear wheel is mounted.  A wheel bracket is journaled on one end of one off-set crank leg and supports a guide member and a helical end cam track.  A follower member having a conjugate helical surface rides on the cam track and supports a locking member on its upper surface.  The locking member is secured to the chassis and includes a plurality of detent teeth between each two of which at least one tooth on the follower member is received to lock the follower in a selec-ted position.  Turning of the knob allows the follower tooth to slide over the detent teeth to allow rotation of the follower which effects a vertical movement thereof on the cam track surface.

Abstract: Abstract of the Disclosure A heat recovery device for recovering waste heat from a hot gas that carries solid and precipitable contaminants of the type given off from the grill area of a fast food restaurant in which a heat exchanger is provided through which these gases are directed for heat exchange with a gas to be heated such as ambient air.  The heated air may then be supplied to the interior of the restaurant or to ambient.  The two gases are directed through sets of spaced passages in the heat exchanger in heat exchange relationship with each other.  A filter is used ahead of the heat exchanger for filtering the hot gas.  This filter is easily removed for cleaning.  A liquid receiving container may be periodically used to replace the filter.  This receives a liquid such as a hot detergent solution that may be used to clean the contaminated passages of the heat exchanger.

Abstract: ABSTRACT An integrated system for measuring and correcting rubber tires for forces generated by dynamic non-uniformities and for measuring and marking both sides of the tire for lack of symmetry.  The force measurements are fed to a com-puter and the forces indicative of dynamic non-uniformities correlated to given angular positions on the tire by means of a pair of transmissions which act as a shaft encoder, the transmissions incorporating computer controlled timing discs which act through an hydraulic controller to control the honing mechanism which  cuts the outside periphery of the tires at the proper locations and in the proper amounts to reduce the non-uniformities to an acceptable low level.  Computer control means are also provided to revolve the tires to the proper positions for the marking of their side walls to indicate points of maximum unbalance so that corrective measures may be there-after taken to correct the tires for lack of symmetry.

Abstract: A B S T R A C T                A water flow control system comprising two water conduits enclosed in a casing, one conduit being the cold water inlet, the second a hot water inlet, wherein the two inlet conduits are parallel and spaced-apart in the upper portion of the casing and coverage in a Y configuration in the lower portion of the casing finally merging in a common outlet.          Two identical pairs, one above the other, and both pairs above the Y configuration, of pressure responsive valves are disposed in the conduits and both valves of a pair, one in each conduit, co-operate by means of a rigid, balanced linkage to a central transverse pivot, whereby, as one valve closes in reaction to increase pressure in its inlet conduit, its correspondin valve in the other conduit opens, as in a teater-totter action, a plate is provided under each valve, has an aperture therein (to permit water flow) and abutment means to limit downward motion of a valve without totally shutting off water flow.  The two identical pairs of valves instantly respond to the slightest pressure difference between the inlet conduits and co-act to maintain a constant outlet water temperature, the only secondary effect being a slight decrease in outlet pressure until initial pressure is restored.

Abstract: CHEESE MAKING APPARATUS                   Abstract of the Disclosure An apparatus for the continuous matting and milling of cheese curd.  The apparatus includes a housing which houses an upper, water-permeable, endless conveyor belt and a lower endless conveyor belt which operates in the opposite direction to that of the first belt.  A mixture of cheese curd and whey is deposited as a layer on the upper belt and the whey is drained through the belt and is discharged through the lower end of the housing.  The matted curd is transferred from the upper belt to the lower belt and as a result is inverted, and is subsequently discharged to a curd milling unit which acts to cut the mat of curd into cube-like chunks.  The curd mill includes a cylindrical drum and a blade extends the length of the drum and is spaced outwardly from the drum periphery.  A series of radial knives connect the blade and the drum.  The drum is rotated through an arc between a cutting position wherein the blade and knives cut the curd mat into cube-like chunks and a retracted position where the chunks fall by gravity from the drum to a collection site.     --O--

Abstract: ABSTRACT OF THE INVENTION            A density monitoring gauge is disclosed which modifies a Bourdon tube manometer by introducing a compen-sating element between the end of the Bourdon tube and the pointer actuating mechanism.  The compensating element is designed to accommodate for changes in circumferential length of the Bourdon tube induced by temperature as well as to compensate for pressure changes in a closed system attrib-uted directly to changes in gas temperature within that closed system.  The compensating means may consist of a bimetallic member having an  ?  configuration.  Alternatively, the compensating means may include a pair of synthetic material rods connected by a thermally stable member such that linear thermal expansion of the rods is additively connected between the tube spring and the pointer actuating mechanism.  The density measuring device is desirably used in connection with sulfur hexafluoride insulated electrical switching gear.  If desired, the density monitor may be arranged with an electrical alarm to indicate the presence of a leak.

Abstract: ABSTRACT       The present invention relates to directing a reading light beam onto the surface of a video disc. Prior art attempts to make use of a reading light beam for contact with the surface of a video disc involved large apparatuses for housing the optical path of the beam primarily due to the length of the light source and the optical devices necessary to direct and control the beam,  The present invention provides an improved apparatus and method wherein the light beam follows a folded path,  In accordance with the inven-tion, a source is provided for producing a reading beam of light radiation.  The reading beam is directed from the light source along a folded, substantially U-shaped optical path and then onto the surface of the video disc.  The reading light beam contacts the information track of the video disc whereupon the beam is modulated by the information track.  A sensor receives the modulated beam of radiation from the information  track,  The folded  optical path takes up less space in the player and therefore makes the player more suitable for home entertainment.
