Abstract: METHOD OF MANUFACTURING AN EMBOSSED             PRODUCT     Abstract A wood product including a quantity of adhesive coated coarse wood particles disposed between a pair of cellulosic fiber webs is embossed in a heated press by means of a caul plate carrying a plurality of inserts adapted to impress a desired relief design comprising a plurality of adjacent but independent panel configurations in the wood product.  The inserts are attached to the caul plate and extend to selected levels for compressing the wood product to different embossing levels characterizing each panel configuration.  The individual caul inserts are machined to shape and are separately photo-etched to receive a desired decorative pattern thereon, after which the inserts are assembled onto the caul plate for impressing the wood product.  The panel configurations produced in the wood product are suitably separated into substantially rigid, embossed furniture elements or parts having a carved or inlaid appearance.

Abstract: ABSTRACT OF THE DISCLOSURE         The electrophotographic process of this invention is achieved by subjecting a photosensitive screen to a matched perfor-mance of voltage applications and image irradiation to form a primary electrostatic latent image for modulating the flow of corona ions to create a secondary electrostatic latent image on a recording mem-ber disposed in close proximity to the screen bearing the primary electrostatic latent image.  The screen is made of a conductive member as its basic element, a photoconductive member covering a substantial part of the conductive member, and a surface insulating member also covering a substantial part of the conductive member and of the photoconductive member, in which the conductive member is partly exposed at one surface side of the screen, or it is entire-ly covered by the surface insulating member with another conductive member to be exposed being provided on said insulating member, and the coating thicknesses of the photoconductive and surface insula-ting members are thicker at the portion opposite to the surface part d the conductive member to be exposed.

Abstract: ABSTRACT OF THE DISCLOSURE    A spark ignition fuel injection reciprocatory internal combustion engine with dual induction system is provided which has within a cylinder head a primary intake passage to direct air fuel mixture charge into a cylinder to swirl therein and a secondary intake passage to direct air charge into the cylinder in such a direction as to impede the swirling motion of the air fuel mixture charge, thereby to maintain the volumetric efficiency of the engine at a sufficiently high level.          A fuel injector is so positioned as to discharge fuel into the primary intake passage. An air flow sensor is provided upstream of primary and secondary throttle valves to detect the total of flow of induction air fed to the engine so that fuel is discharged at a rate proportional to the total induction air flow.  Under engine operating conditions when only the primary throttle valve opens, air fuel mixture charge will swirl at a sufficiently high rate as to enhance evaporation and dispersion of fuel droplets.  Under engine operating conditions when both the primary and secondary throttle valves open, air fuel mixture charge issuing from the primary intake passage is enriched and air charge from the secondary intake passage will impede swirling motion of enriched air fuel mixture charge from the primary intake passage, thereby to enhance evaporation and dis-persion of fuel droplets.

Abstract: FILTER WRENCH              Abstract of the Disclosure A filter wrench includes a cylindrical housing with internal lugs and a centrally positioned punch for draining and removing a screw-on filter having an outer canister and an inner filter element.  As the housing is impactively positioned over the filter, the punch successively punctures the outer canister and then the inner filter element before the lugs indent the outer canister and the bottom of the housing abuts the canister.  With the punch extending through the punctures, the housing is held on the filter while the outer canister and the inner filter element are drained through passages in the punch and an outlet in the housing.  When draining is complete, a formed nut on the outside of the housing allows the filter wrench to be rotated causing the lugs to rotate the filter for removal.

Granted: 1982-03-16
Abstract: ABSTRACT OF THE DISCLOSURE:          A tire, and a combination of said tire with a rim that yields improved stability characteristics when the tire is run flat.  The combination of this invention yields a structure wherein the tire will operate normally under normal conditions of load and pressure and will operate with the load equally distributed on each sidewall of the tire during run flat operation.  In this invention, the tire has an asymmetric sidewall construction resulting from the inclusion of rubber inserts in its sidewalls of different bulk and the rim has axially outward extending rim flange extensions which are angled in relation to the axis of rotation of the rim.  The extensions are angled in opposite directions.  The proper combination of these features compensates for the camber that the tire is subjected to when it is run flat.

Abstract: PRESSURE-RESPONSIVE SURGICAL         TOOL ASSEMBLY             ABSTRACT OF THE DISCLOSURE   A pressure-responsive surgical tool assembly includes an inflatable enclosure and a pair of electrodes posi-tioned therein.  The electrodes are adapted to contact each other and operatively move away from each other under an increase of fluid pressure inside the enclosure until electrical contact is broken.  An electrical lead is connected to each electrode for electrically monitor-ing the condition of electrode contact.  A flexible tubing is connected to the enclosure to provide fluid flow there-in to increase the pressure inside.  A surgical tool overlies at least one of the electrodes and is adapted to transmit force applied from it to that associated electrode.  Application of force by the tool initially causes the electrodes to contact each other and to remain in contact until the pressure inside the enclosure substantially balances the applied pressure from the tool whereupon electrode contact is broken.

Abstract: CONTROLS FOR HYDRAULIC PERCUSSION DRILL               ABSTRACT OF THE DISCLOSURE       A control system for a hydraulic percussion rock drill and feed mechanism including a single constant power hydraulic pump for supplying pressure fluid to operate the feed mechanism, drill stem rotation motor, and the percussion hammer.  The drill feed, rotation and percussion functions are controlled_by indi-vidual manually actuated pressure compensated valves.  Fluid pressure to the feed mechanism is controllable at one of two selectable pressures and is automatically reduced if fluid pressure to the drill stem rotation motor exceeds a predetermined limit.  The drill percussion blow intensity and frequency is controlled by a mechanism responsive to a fluid pressure signal which is automatically operated to provide for a high blow frequency and low blow intensity operating mode when the drill is retracted away from the workface.  The constant power hydraulic pump is provided with a control which will adjust the pump output to a partial displacement setting when the drill is being retracted away from the workface.  Alternatively, the pump control may be set to full displacement with a power limit and the drill percussion mechanism fluid supply may be automatically throttled when the drill is being retracted away from the workface.
