Abstract: ABSTRACT OF THE DISCLOSURE           Automated visual display apparatus includes a band of flexible, translucent material formed as a series of pockets adapted to receive and carry pictorial displays.  A pair of terminal rolls support the band and are reversibly driven by a motor to controllably displace the pictorial displays past one or more viewing apertures in a cabinet containing the apparatus.  Encoded control information is carried on the band and is sensed to enable a logic circuit to selectively energize and deenergize the motor to advance or return the displays.  Similarly, the logic circuit selectively energizes and deenergizes a light source to illuminate the displays only after the displays have stopped at respective viewing apertures.

Abstract: Abstract of the Disclosure Apparatus for injection moulding thermoplastic material is disclosed wherein a heavy-duty sprue bush is heated along a substantial portion of its length to keep the thermoplastic material from solidifying during interruptions in the moulding cycle.  The apparatus provides for minimal contact between the heated sprue bush and the moulding die to prevent heat transfer between them.  This is achieved by maintaining an air gap between the bush and the die except at points where the thermoplastic material passes into the moulding cavity.  Sprue runners oriented generally parallel to the mould joint line are aligned with cavity injection openings which are similarly oriented.  These injection openings pass through a thin wall of the mould that extends generally perpendicularly to the joint line such that when the moulds are open, the sprue is cleanly severed from the moulded article.

Abstract: UNLOADING MEANS FOR A GAS COMPRESSOR            Abstract of the Disclosure In the embodiment shown, the invention com-prises a suction/check valve interposed in a gas inlet channel, the channel being open at one end for communication with the atmosphere, and at the opposite end for communication with a gas compres-sor inlet port.  The valve has a bleed hole formed therein for slowly blowing down the compressor receiver at shutdown.  A second check valve is oper-atively interposed between the receiver and the atmosphere for depressurizing the receiver when the compressor unloads.  A conduit which communicates with both valves provides a valve-operating, fluid, pilot-pressure to close off the suction/check valve, and to interdict its bleed hole, and to open the second check valve, with compressor unloading.

Abstract: ABSTRACT OF THE DISCLOSURE         A reinforcement cord for elastomers comprises three generally parallel and coplanar main wires of steel extending longitudinally as a group in edge-to-edge contact with one another. A wrap steel wire similar to these main wires is wound around the group of main wires. When the cord of the invention is embedded in an elastomer, each and every wire is in contact with the embedding elastomer.  Thus, transmission of tension between the wires and the elastomer is maximized, while protection of the wires both from corrosion and from rubbing on one another is minimized.  The cord of the invention is particularly suitable for use in tires, inner tubes, conveyor belts and the like.

Abstract: PHF. 80-502                 -20-ABSTRACT     This circuit comprises a phase comparison stage and a synchronising control stage.  The phase comparison stage includes a reference oscillator, a frequency divider connected to the output of the oscillator and whose output signals constitute the useful line deflection drive signals, as well as a phase comparator comprising a logic circuit and a counter.  The logic circuit receives synchronising signals and the counter, which is connected to the output of the oscillator produces a signal which is representative of the phase deviation detected in control stage, the latter comprising a state detector for detect-ing the synchronised state, in which the phase deviation detected is below a limit value or the unsynchronised state division ratio of the frequency divider.  This fre-quency divider comprises a counter, an adder, and a decoder the output signal of which is stabilised by means of a stabilising stage.  The circuit consists for the major part of digital circuits.

A method for attaching detachable snells to a fishing line while the line system is being set out from a moving vessel at sea.  The snell and the line have cooperating coupling members consisting of a peg with stop studs rotatably attached to the line and a radi-ally elastic ring attached to the snell, the ring being detachably fastened to the peg by being pressed down into a locked position behind the stop studs.          The line is drawn through an apparatus having a peg orienting means, and the pegs pass a discharge open-ing on a ring magazine where each peg is brought into engagement with the central opening of a discharged ring and carries the ring along with it to pass between two converging surfaces whereby the ring is pressed down into a locked position on the peg.  The converging surfaces consist of a pressure surface for the ring provided with a guide/clearance groove for the peg, and a backstop surface for the peg.  The discharge opening is arranged at the forward edge of the pressure surface at the entrance to the converging surfaces and is adjacent to a ring feed regulator in which the primary plane of the ring forms an acute angle relative to the path of advancement for the peg such that the peg enters the ring and carries it along, as mentioned above.

Abstract: ABSTRACT OF THE DISCLOSURE         To uniformly and economically disperse liquids, via sprays of droplets, on surfaces of particles, a method of moving the particle involves their rotary lifting, followed by their free falling, with a pray of droplets originating from a central area of the overall motion path of the particles.  In a preferred embodiment of the blending apparatus, a hollow drum is rotated about a near horizontal axis.          Inside the drum, commencing at each end are cantilevered non-rotating shafts, each positioning one or more powered slightly conical discs selectively tiltable to ultimately disperse respective sprays of drop-lets from a central area.  This central area is defined by particles being lifted while centrifugally held to the interior of the drum and then at a zenith locale the gravitational force becomes effective enough so the particles drop in an arcuate cascade path back to the interior surface of the drum to start another cycle.  The cycles are predetermined to continue until the particles acquire the selective quantity of dispersed droplets on all of their surfaces.  Then the particles leave the interior of the rotating hollow drum opposite the end of their entry into the drum.  This method and apparatus is parti-cularly useful in treating with liquid resin binders, and/or wax emul-sions, thin wood wafers, wood flakes, wood shavings, sawdust and other particles of like respective sizes, which often are subsequently collectively formed and pressed into products, such as wood wafer boards.
