Abstract: Laminated slabs superficially bonded together are prepared by autoclaving a vertically compressed stack including a plurality of the sheets when initially set but not finally cured and having a polyethylene or like plastic film-like layer sandwiched between each pair of the sheet surfaces to be bonded together. A layer of material other than asbestos-cement may be sandwiched between the asbestos-cement sheets, for example, metal foil, to make the slab moisture-impervious or an array of filaments or wire-mesh material as reinforcement may be used.

Abstract: The wheel hub cavity is used to accommodate a portion of the air bellows in an axle suspension of either the single or tandem drive axle type enabling the air bellows to be located directly over the axle and under the frame. The resulting lightweight, high load carrying capacity structure includes control arms for aligning and stabilizing the suspension and air bellows at both ends of the axle, adjacent the axle housing and extending outboard into the wheel hub cavity.

Abstract: Provided is a device for preventing the inward deformation of a hollow plastic container which would normally inwardly deform after closure due to the cooling of hot liquids therein. The device comprises a membrane extending across the container spout for sealing the spout, which membrane is more flexible than the walls of the container, means for securing the membrane into sealing engagement with the spout, and means for applying the ambient pressure existing on the outside of the container to the outside of the surface of the membrane.

Abstract: Provided is a vehicle for hauling and dispensing grain of the type which includes a grain body and underbelly dispensing gates in the body. Each underbelly dispensing gate rotates about its own central shaft actuated by a detented lever mechanism. The portion of the gate which must move upward to open the gate and initiate dispensing is overshadowed by a convex member which provides a cavity vacant of grain thereby allowing the gate to be opened even when the body is filled with grain.

Abstract: An axle suspension particularly applicable to trailers includes an elongated, substantially rigid beam, a pneumatic bellows located at one end of the beam, a hanger bracket located at the other end of the beam, an axle connecting means rigidly connected to the beam and axle, and an elastomeric bushing structure located at or near the pivot connection between hanger bracket and beam which has a different degree of deflection beamwise than hangerwise, is sufficiently rigid to provide suspension stability and is sufficiently resilient to allow operative deflections in response to articulations of the suspension to maintain substantially constant the distance between the hanger bracket and the axle connecting means.

Abstract: An aerator for use on water faucets having a metal casing and a one-piece plastic insert that includes both the diaphragm for directing a large number of water jets in a downstream direction and a ledge for holding a screen to mix said water jets with air. The one-piece molded plastic insert is held in the casing due to compression between the downstream end of the faucet and an inturned ledge or lip at the downstream end of the metal casing. The one-piece insert defines air intake passageways passing along the inside wall of the casing and entering the mixing space between the diaphragm and the screen. The plastic material is soft enough so that the upper end of the one-piece plastic insert makes a substantial seal with the faucet. If some water does pass this seal, it enters the air intake passageways and passes out the downstream end of the casing. Slits are provided in the side wall of the insert to enhance the molding of the insert.

Abstract: A conduit is traversed by a screw, which screw may or may not be capable of rotating within the conduit, the screw alone, or the screw together with the conduit, become rotatable around their common axis when fluid under pressure enters from one end of the conduit, exits from the other by traversing the helical path of the screw. The construction in which the screw is rotatable within the conduit is found suitable for producing a pulsating stream of water and for building showerheads for selectively producing different types of streams, such as (a) pulsating stream, (b) spray, and (c) soft bubbly aerated stream. Various valves manually operated by a part of the showerhead perform the selection. The pulsating stream is achieved by a screw having helical threads that makes a snug fit with the inside wall of a cylindrical pipe through which the water flows; the flow rotating the screw which in turn operates a valve that at least partially interrupts the flow of water through an outlet orifice.

Abstract: A machine for packaging chickens in plastic bags comprising tong-like gripper means which engage the legs of a chicken as it comes from a conveyor, a hopper into which said gripper means force the chicken so that its legs come to lie at the side of the body, the hopper having a bottom adapted to be withdrawn in transverse direction, a plastic bag mounted below the hopper, being adapted to be inflated and held by supporting means to receive said chicken, the top of the filled bag being clamped by transporting clamps which guide it into means for gathering the top of the bag and closing it by a clip.

Abstract: A hollor tubular shaft containing optical elements for a laser-type facsimile transceiver employing helical scanning is horizontally supported by air bearings, and translated along its major axis by means of a piston and pneumatic cylinder coaxial with the shaft. An integral reaction-powered air motor provides shaft rotation, and a fail-safe automatic control and braking system prevents damage to the scanning mechanism in the event of interruption of the pneumatic or electrical supplies by permitting physical shaft-to-bearing contact only in the absence of shaft rotation and translational motion. The apparatus finds particular utility in the production of printing plates for use in the Graphic Arts.

Abstract: Step attenuators wherein a number of individual attenuators are connected in series, with a switch across each individual attenuator, are well known. By opening and closing particular combinations of the switches, any one of a number of different values of attenuation may be selected. Each individual attenuator has in the past, as well as in the present invention, had a characteristic impedance equal to the impedance of both the signal generator (which feeds the input of the step attenuator) and the load (connected across the output of the step attenuator). However, the switches for selecting the individual attenuators may have substantial resistance especially where solid state switching diodes or mercury wetted reed relays are employed. The latter type switches display resistances caused by skin effect at highter frequencies. This causes inaccuracies of the attenuation steps due to mismatch, in prior art systems of the type described above.

Abstract: A combination scoop and plunger for corralling refuse in a kitchen sink and forcing it through the drain opening into the garbage disposal area, comprising a single molded plastic scoop and bellows arrangement, having within its hollow portion a hollow plunger whose neck portion is removably connected to the upper portion of the bellows and which may be provided with cleanser that can be dispensed therefrom. When the bellows are collapsed, the bottom portion of the plunger contacts the refuse, forcing it through the drain opening.

Abstract: A brace for supporting a dump body of a vehicle including means for attaching the brace to a long sill of the body, means for supporting the weight of the body on the vehicle chassis, shaft means rotatably attaching the support means to the attaching means, means for retaining the support means on the long sill of the body and means normally biasing said retaining means into engagement with the long sill of the body. The brace is lowered into position by pulling against the biasing means until the retaining means are disengaged from the body long sill and rotating the brace to its down position. The brace is raised by pulling against the bias, rotating the brace to its retained position and allowing the biasing means to lock the brace into position.

Abstract: A hollow building block filled with insulation is shaped as a pair of proximal but offset rectangles thereby to form steps at diagonal corners for fitting adjoining blocks together. A continuous insulation effect is obtained because the insulation in each rectangle extends beyond that of its proximal rectangle and overlaps with the insulation in the proximal rectangle of each adjoining block. Aligning holes and reinforcing grooves are provided for rapidly constructing strong structures from the blocks.

Abstract: A hollow tubular shaft, containing optical elements for use in a helical scanning facsimile transceiver, is supported horizontally by air bearings and translated linearly along its major axis through cylindrical reading and writing stations by means of a pneumatic cylinder and piston coaxial with the shaft. An integral reaction-powered air motor provides shaft rotation, and laser beams perform the reading and writing operations, both of which may take place within the same apparatus or either one of which may be executed at a location remote from that of the other.The reading station contains an optical encoding pattern enabling continuous control of the position of the radiation beams relative to the indicia being read, and an electronic memory facilitates the temporary storage and manipulation of information to be recorded by the writing station. A fail-safe system prevents damage to the scanning mechanism in the event of interruption of the pneumatic or electrical supplies.

Abstract: This invention describes a pickproof lock consisting of a rotating cylinder provided with two sets of opposing tumblers. The tumblers permit a very thin key to be inserted between them. The key is made of a ribbon material of the order of one-hundredth of an inch thick and the tumblers are displaced in both directions from the center so that manipulation of a lockpicking tool becomes very difficult, since the tool must be as thin as the key and each set of tumblers must be in the correct position for the cylinder in turn.
