Abstract: 1,046,077. Laminates and laminating. PACIFIC VEGETABLE OIL CORPORATION. March 3, 1964 [March 4, 1963]. No. 8890/64. Heading B5N. Laminates comprising upper and lower layers e.g. of sheet material such as plywood, cementasbestos, paper, aluminium foil, mineral material or paper/aluminium combined sheets, and core material of foamed plastics such as phenol-, urea- or melamine-aldehyde resins, polyvinyl chloride, or epoxy or polyurethane resins, are made by extruding the foam material between the outer layers, from a nozzle or nozzles occupying substantially the whole space between the layers, and moving the layers relative to the extrusion nozzle or nozzles. In Fig. 4 (not shown) the layers 34, 35 are enclosed in and secured, as by clamps or vacuum cups, to a rectangular mould box 37, 38, 41, and the nozzle 17 is moved backwards by the pressure of the extruded foam. The nozzle comprises a flared portion 14, a wire grid or perforated plate 17 and rubber sealing blocks 18, 19. For sealing corrugated or internally undulated layers during treatment a nozzle is used comprising upper and lower movable layers spaced apart by a spring and connected by gusseted side walls. Two or more nozzles may be used in parallel. In Fig. 9 (not shown) layers 60, 61 are fed continuously between endless belts 66, 68 closed at the sides by blocks 71, and the delivery pipes 20 of nozzles 17 carry pistons 47 in cylinders 45 to either end of which compressed air may be admitted, or air released via cocks 52, 53, to regulate the movement of the nozzles.

Title: Input circuit for an automatic telephone answering device
IPC: H04M11/00
Filed: 1972-02-25
Abstract: 1370196 Telephone answering machines PIONEER ELECTRONIC CORP 25 Feb 1972 [27 Feb 1971] 8924/72 Heading H4K In a circuit for an automatic telephone answering device a calling signal detector causes a contactless switch in series with the line to be closed, thereby looping the line. The circuit comprises a starting circuit A 1  connected across the wires L 3 , L 4  of the telephone line via D.C. blocking capacitors C 2 , C 3 . When ringing current is received over the line a potential is applied to the base of transistor Tr 3  to switch it on and loop the line between 3 to 10 seconds after the commencement of ringing. The starting circuit also sets the answering device into operation. After a predetermined time, e.g. 50-60 sees. transistor Tr 3  is switched off and the answering sequence is terminated. Diode bridge D 2 -D 5  renders the transistor immune to polarity reversals on the line and choke AFC prevents A.C. signals from being applied across the transistor. Transformer T 1  and capacitor C 1  are used to A.C. couple the speech input and output circuits of the answering device to the line. Tr 3  may be a field effect transistor or any suitable contactless switch.

[Also in Division B3] Recesses 2, 2 for the half-cores 3; and 4 for an inter-head shield (not shown) are provided in the half housing 1 of a binaural half-head assembly, the cores 3 being advanced into contact with a dummy shield member 6 and cemented with a polymerizing non-solvent adhesive which fails to adhere to the member 6 which is preferably of a fluorinated thermoplastic or of pregreased metal. The dummy 6 is removed before or after grinding the shaded core faces and pairs of half-heads assembled about a single shielding plate and secured by encapsulation. The running face is then finished by machining to the line 8. When the half-cores are made of metal laminations, these are forced against a transverse wall 9 and the dummy 6 to ensure compaction at the transducing region. As an alternative, the cores 3 and dummy 6 may be held in a jig and the member 1 moulded about them, the dummy being removed to reveal the recess 4 for the shielding plate as above.

Abstract: 809,002. Crimping yarns; twist tubes. DUBINI & CO. S. A. G. March 28, 1955 [March 27, 1954], No. 9039/55. Classes 120(2) and 120(3) In a process for treating threads of synthetic fibre, each thread F, Fig. 1, is continuously fed between entrance and exit points 3 and 4 whereat it is held against rotation about its axis i.e. the points form twist stops and passes through a falsetwister 5 the twist imported by which is set by heat-treatment effected by passing all the threads simultaneously through a single heating chamber, as at 8. Each false-twister 5 may comprise a tubular body 5<SP>1</SP> through which passes a thread after it has been inserted in one of the hooks as at 6, on one side of the end flanges 7. In the apparatus shown in Fig. 2, threads F drawn from spools 1 supported on a loading floor 9 pass through two lines 10 of guides, adjustable tensioning bars 11, 12, to a feed roller 13 co-acting with individual rollers 14 to form the twist stop 3. All the threads are heated in a chamber 8 constituted by a doublewalled insulated box fitted with tubular guides 16, 16<SP>1</SP>, forming flared yarn inlet and outlet funnels, and accommodating heating means 17 e.g. an electric heating element (which may be screened, as at 18), which maintains a constant predetermined temperature within the chamber. The threads pass through false-twisters each mounted on a pivoted support which is spring-urged to maintain the twister resiliently in contact with a driving belt 19. The twisters are arranged in parallel rows and the belt 19 passing therebetween bears tangentially on alternate twisters so as to impart opposite rotation thereto. The threads then pass through guides 25, over a driven roller 26 co-acting with idle rollers 27 to form the twist stop 4 and is wound on a bobbin 2. The rolls 26 may have a peripheral speed higher or lower than that of roller 13 to effect stretch or allow contraction of the threads during treatment.

Filed: 1941-07-18
Abstract: 548,445. Electromagnetic relays. LANDIS & GYR SOC. ANON. July 18, 1941, No. 9118. Convention date, July 20, 1940. [Class 38 (v)] Relays of the plate armature or other type which are responsive to special frequencies of AC. superposed on a network and are connected to the network through a rectifier are made so that they " release" at a voltage comparatively little below that at which they attract by the use of resistances. In the form shown in the Figure, the relay R responds to current in the tuned circuit 5 and in addition to operating main contacts r<SP>1</SP> moves a switch r<SP>2</SP> so that a resistance 9 is substituted for a rectifier 8. Thus the amount of D.C. current traversing the relay is reduced. In modifications the relay has two coils and operates to switch a resistance in parallel with a rectifier, or it may remove a short-circuit from the resistance. The Specification as open to inspection under Sect. 91 also describes other modifications, in which a reverse winding is energized upon Operation of the relay, or is permanently connected to the network. This subject-matter does not appear in the Specification as accepted.

Title: Counter circuit
IPC: H03K3/287
Filed: 1966-03-03
Abstract: 1,091,754. Transistor frequency divider circuits. RADIO CORPORATION OF AMERICA. March 3, 1966 [March 19, 1965], No. 9329/66. Heading H3T. A frequency divider or counter comprises a pair of transistors 20, 40, reciprocally coupled so as to form a bi-stable multi-vibrator, a further transistor 60 and capacitor 66 being included in the coupling between transistors 20 and 40 so as to form a ramp generator which inhibits the circuit against triggering for a predetermined number of input pulses. The circuit can thus divide the frequency of input pulses at A by factors greater than 2, e.g. 5, 7 or 13. Assuming transistors 20 and 80 to be on and transistors 40 and 60 to be off, the next pulse at A is differentiated at 31, giving a negative pulse which is passed by a steering diode 33 to turn off transistor 20 and hence turn on transistors 40, 60. Capacitor 66 discharges, turning off transistor 80 and blocking steering diode 33. The discharge of capacitor 66 is terminated by the next pulse at A which after differentiation at 11, is passed by diode 13 to turn on transistors 40, 60 and turn off transistor 20. Diode 33 now blocks a predetermined number of succeeding input pulses until capacitor 66 has re-charged sufficiently to turn on transistor 80 and diode 33, restoring the circuit to its original state. In a synchronizing pulse generator for a colour television system, three circuits as shown may be connected in cascade providing respective division ratios of 7, 5 and 13 so as to reduce a frequency of approximately 3À5 Mc./s. to approximately 7À8 kc./s. The division ratio is maintained despite wide variations in input frequency since the extent of discharge of capacitor 66 is determined by the inter-pulse period of the input wave.
