Abstract: 646,923. Book-binding. CRABTREE & SONS, Ltd., R. W. April 30, 1947, No. 11645. [Class 16] A book-binding machine performing rounding and backing operations comprises a first pressure device which exerts a light pressure to a group of signatures forming, a filler, a second device to exert a heavier pressure on the filler, continuously-moving endless conveyers having parallel runs providing substantially continuous parallel moving surfaces to receive fillers between them, the conveyer runs passing successively to the first and second pressure devices, and rounding and backing components disposed to vibrate against the fillers whilst they are subject to the light and heavy pressures, respectively. As shown, the signatures S are fed past a pair of rounding rollers 3 and then past a pair of backing rollers 7 by a number of slats 2, carried on two pairs of endless chains 10, 11. The slats 2 are made to bear lightly on the signatures by pressure bars 14, 15 as they pass rounding rollers 3, and to bear with increased pressure as they pass the backing rollers 7, by means of pressure bars 16, 17 and pressure rollers 8, 9 which bear on the fillers adjacent to their spine. The pressure bars 14-17 are adjustable by handwheels 14<SP>1</SP>-17<SP>1</SP> rotatably attached to fixed reaction plates 14<SP>3</SP>-17<SP>3</SP> and which engage threaded studs 14<SP>2</SP>-17<SP>2</SP> secured in the bars. The rollers 8, 9 are similarly adjustable by handwheels 29, 30 rotatably coacting with the fixed reaction plates 163, 173. The rollers 3, 7 are vibrated against the signatures by slides 20, Fig. 5, carrying the rollers 3 and 7 and which are reciprocated by a driven cam 24 engaging a roller 22 resiliently mounted on the slide. The Provisional Specification describes the pressure bars as being formed by opposed pressure tables, one of which can extend the whole width of the machine to form the back support for one chain and the other'forming the backing support for the other chain and which is in two halves so that the light and heavier pressures can be effected.

Title: Improvements in and relating to high vacuum pumps
IPC: F04F9/00
Filed: 1963-03-26
Abstract: 1,008,968. Diffusion pumps. A. R. RANGABE. June 22, 1964 [March 26, 1963], No. 11813/63. Heading F 1 E. In a diffusion pump having an outlet opening 6, Fig. 1, connected to a backing pump, a container 3 connects with a locally-heated nozzle 12 positioned at the level of the operating liquid 4 so that a vapour jet is directed from the nozzle to entrain gas particles from an inlet 7. The base of hood 1 is sealed in an annular sump containing an organic liquid or a metal e.g. bismuth, tin, indium, lead or other alloys, to be vapourised. The sump drains through tube 5 to a nozzle 12 which is heated by a coil 9 fed through leads 10 which pass through terminal seals 11. Cooling fins 8 join hood 1 to chamber 2 and a port 1a provides for the reduction of the pressure difference across hood 1. In modifications tube 5 may be of a refractory material and nozzle 12 may be of Venturi form or have a double wall. The metal may be heated by passing electricity directly through it or by adjusting the electrical resistance of the nozzle wall at a desired position. Metal vapour is discharged from the nozzle 12 upwardly against the hood and entrains gas particles from inlet 7. The vapour condensing on the hood runs back into sump 3. In another embodiment the nozzles of a two-stage pump are arranged as annular troughs 13, 15, Fig. 2, of refractory material e.g. molybdenum or alumina which are heated by coils 18, 22 secured by alumina coating to their sides and bases. Vapour emerges from the first stage hood 1<SP>11</SP> to be entrained by vapour from trough 13. Metal from pump 31. overflows back to sump 3<SP>11</SP> via tube 17. The metal may be heated by induction heating, electron bombardment or by passing a current through the metal or trough. Annular heat localizing shields 27 may be provided. Head shields may be provided on leads 19, 23.

Title: Improvements in gain-control systems of radio receivers
IPC: H03G3/26
Filed: 1943-07-21
Abstract: 564,917. Valve circuits for wireless reception. SMITH, J. WARDLEY-. July 21, 1943, No. 11903. [Class 40 (v)] In a radio receiver having an inter-station noise suppressor circuit associated with a valve of the receiver adapted to amplify a carrier wave modulated by the received signal, said valve is associated with biassing means tending to bias it substantially to or beyond cut-off, a first rectifier is arranged to be energized from an input coupling circuit of said valve to provide a voltage reducing the bias on said valve, and a second rectifier is arranged to be energized from an output coupling circuit of said valve to provide a voltage supplementing the effect of said first rectifier on said valve. An intermediate frequency amplifier V having input and output transformers Tl, T2 respectively, has its cathode connected through resistances R1, R2 to H.T.- and through resistance R3 to H.T. +, thus giving the cathode a considerable positive potential. The grid is connected to H.T.- through the secondary of T1 and resistors R4, R5. Valve V is thus normally biassed to or beyond cut-off. Two diodes D1, D2 fed respectively through C1, C2 from the input and output circuits of valve V, have the positive ends of their load resistances R6, R8 connected through smoothing resistances R7, R9 to the junction of R4, R5. A third diode D3 is connected between the junctions of R1, R2 and R4, R5. In the absence of a signal, valve V is cut off, but when a signal appears at T1, part of it is rectified in D1 and the voltage across R6 is applied across R5 to reduce the bias on the grid of V which then conducts. The consequent output, rectified in D2 gives a voltage across R8 which is applied across R5 to reinforce the effect of D1. The normal bias for V is equal to the voltage drop across R1. When the voltage across R5 exceeds a certain value, D3 conducts and prevents the bias being reduced beyond its normal value.. The lower end of R5 may be connected to a tapping on R2 so as to allow the cut-off point of V to be adjusted.

Abstract: 1,187,943. Semi-rotary-piston I. C. engines. R. JAMES. March 12, 1968 [March 15, 1967], No.12051/68. Heading F1F. A two-stroke I. C. engine has pistons 35, 36, 38 that are integral with one another and oscillate within a housing 12 to effect rotation of a crankshaft 80 connected thereto by a rod 82, the piston 38 serving to pump fuel-air mixture into chambers 31, 32 defined partially by fixed partitions, or heads, 24, 25 and containing the other pistons, respectively, which produce useful power. Compressed mixture in the aforesaid chambers is ignited by spark-plugs 77, 78, grooves 68, 69, 71, 72 being formed in the outer pistons and the heads to provide combustion chambers for the ignited mixture. Fresh mixture is drawn into a chamber 29 containing the central piston through a port 47 controlled by a head 50 on said piston. After compression in the chamber 29 the mixture is transferred to one or other of the adjacent chambers through ports 52, 55, or 57, 59, and ducts (53, 58, Fig. 1, not shown), therebetween, which ports are controlled by the outer pistons. Exhaust gases escape through ports 61, 62. In another embodiment, Fig. 7, transference of the mixture is effected through ports 90, 100 controlled by valve-members 91, 102, which are either pressure actuated or actuated by the central piston. In yet another embodiment, Fig. 8 (not shown), the valve-members 91, 102 are actuated by crankshaft-driven cams (108). In a further embodiment, Fig. 9, transference of the mixture is effected through two sets of ports 125, 127 in one or both of a pair of plates 120 (121, Fig.10, not shown), fixed to the axial ends of the central piston. Transference occurs when one set of ports overlaps one of the heads 24, 25. Ports (129), or 133, may be provided in the end walls of the housing to facilitate transference through the ports 125, 127. The plate (121) may be omitted. Single ports instead of sets thereof may be provided. It is indicated that useful torque may be transmitted through a shaft 40, on which the pistons are mounted, instead of through the crankshaft.
