Abstract: A rotating brush assembly is disclosed for a vehicle washing apparatus which is mounted by a single support arm on either or both sides of a vehicle washing apparatus. The brush assembly, which includes a brush, a brush shaft supporting the brush, a brush motor for driving the brush shaft and a flexible spring coupling such as a single coil spring is permitted to swing or tilt in response to the force exerted on the brush by the movement of the vehicle relative to the vehicle washing apparatus. The flexing action of the flexible spring coupling which couples the brush shaft to the support arm permits the brush to tilt or swing in any direction. For example, when the brush assembly engages the front of a vehicle, the flexible spring coupling permits the brush to tilt as it passes along the front end of the vehicle. The flex of the flexible spring coupling urges the brush toward its normal operating position.

Abstract: The disclosure is directed to a rotary wall deslagger for cleaning boilers. In accordance with the invention, an extensible rack element is selectively, mechanically coupled to a rotatable lance tube of the rotary wall deslagger to move the lance tube between a working and non-working position.

The vanes of the rolls have arcuate recesses or grooves which correspond to the mandrel surface, which overlap each other circumferentially about the mandrel surface, and which are so positioned about their respective axes that the vanes of any given shirring roll directly follows a vane of the preceeding shirring roll taken in the direction of revolution and in the direction of advance of the tubular material.

Abstract: The jugular veins of chickens and other poultry are rapidly cut with precision and uniformity as birds are conveyed in succession past a rotary cutting knife. The necks of the birds are stretched at the cutting station by the coordinated action of upper camming bars acting on the bodies of the birds and lower spaced guide bars between which the necks travel longitudinally with the heads of the birds constrained below the guide bars and sliding on a spring-loaded pivoted pan structure which assures stabilization of the heads at the moment of cutting the jugular vein regardless of variations in head size and weight. The heads are presented to the knife with better vertical orientation to insure better engagement of the knife with the jugular vein. The necks are propelled through the cutting station by pusher elements attached in spaced relationship to an endless conveyor element immediately above the constraining parallel guide bars.

Abstract: A fluid power operated fish skinning machine that severs the tail and impales the fish on a wheel. The fish is then rotated past cutting stations where the dorsal fins are removed and the belly flap is cut.

Abstract: A fluid pressure operable jacking tool having oppositely disposed locking arms. With the draft key and coupler removed, the locking arms of the jacking tool, when installed, biasingly engage the coupler cross key slots formed in the draft gear yoke, so that a fluid pressure powered ram of the jacking tool abuts against the draft gear follower. A fluid pressure line is connected to the jacking tool and, when provided with fluid pressure, causes the jacking tool ram head to compress the draft gear to allow removal of the draft gear and jacking tool from the car center sill together. Once removed, pressure is released from the jacking tool to permit separation thereof from the draft gear. If the draft gear is to be installed, a reverse procedure would be employed.

Abstract: In the disclosed method, dopant atoms of a first conductivity type are implanted into the surface of a semiconductor substrate to form a channel region of each transistor having a relatively high dopant density at a predetermined depth below the surface and a substantially lower dopant density at the surface. This eliminates reachthrough in the channel without adversely increasing the channels threshold voltage. Thereafter, dopant atoms of a second conductivity type are implanted into the substrate to form source and drain regions adjacent to the channels having a depth of less than 0.3 .mu.m below the surface. This minimizes the radius of curvature and corresponding depletion width at the respective junctions with the channel. Subsequently, a patterned insulating layer is formed on said surface at temperatures that are far below the insulating layer's flow point. This avoids diffusing the distribution of the implanted dopant atoms.

Abstract: A method of making a metal-oxide-semiconductor device is disclosed. A thin silicon dioxide insulating layer is formed on the surface of a planar silicon wafer. A first layer of intrinsic polycrystalline silicon is deposited over the dioxide layer, and a second layer of doped polycrystalline silicon is deposited over the intrinsic layer, thereby forming the gate. Subsequent hot processing steps result in diffusion of a portion of the dopant from the doped polycrystalline layer into and throughout the intrinsic layer so as to dope the latter. A metal contact layer is then deposited onto the gate and in superimposed vertical alignment with respect to the thin silicon dioxide insulating layer. The intrinsic nature of the first polycrystalline layer reduces grain growth and void formation in the polycrystalline silicon and thereby prevents the silicon dioxide from being attacked by hydrofluoric acid seeping through voids in the polycrystalline layer during subsequent processing.
