Patent GB-808283-A (GB)
Title: An axial extruding machine
IPC: B29C48/06
Filed: 1955-09-30
Abstract: 808,283. Coating wires &c. by extrusion. BUZULUK KOMAROV NARODNI PODNIK, and NOVAK, V. Sept. 30, 1955 [Oct. 25, 1954], No. 27861/55. Class 87(2). A hollow screw conveyer 1 is mounted on a tube 3, both rotatable together, and a double thread 12 on the surface of the supporting tube 3 provides a channel for cooling the screw by liquid which enters from a chamber 17 through a port 18 and passes along a groove 13 and leaves along a groove 14 and through a chamber 19. The screw 1 fits in the liner 11 of a cylinder 10 from which a nozzle 9 is supported through a member 21, being held agains the pressure of the material by a screw cap 22. The inside of the nozzle 9 and member 21 together form continous converging internal conical surfaces. A guide tube 5 within the tube 3 narrows to a discharge opening 24 coaxial with the orifice 23 of the nozzle 9. The guide tube 5 can move axially within limits but is prevented from rotation. The discharge ends of the supporting tube 3 and of the guide tube 5 are enlarged and shaped so that together they form external conical surfaces stepped to receive a ring 8, supported by webs 25, which centre the end of the tube 5 and is also shaped to form part of an external conical surface. Coating material, e.g. insulation, is impelled by the screw 1 and guided to the orifice 23 between the internal and external conical surfaces. Elongated material to be coated, e.g. wire, is caused, in known manner, to pass through the guide tube 5 and its opening 24, and the wire leaves the orifice 23 provided with a uniform coating. The cone parts 2 and 4 at the ends of the tubes 3 and 5 are formed with opposite transverse bearing faces and the back pressure of the material behind the orifice forces the faces together, the tube 5 shifting axially, and seals against escape of material. When the back pressure is insufficient the faces are kept in contact by a spring 7 which presses on a flange 26 on the end of the tube 5, through which also bolts 6 pass to prevent rotation.

Patent GB-602426-A (GB)
Title: Manufacture of aromatic acyl-sulphonamides
Filed: 1945-10-24
Abstract: Acyl-sulphonamides are made by reacting naphthyl-, anthryl-, or phenanthryl-sulphonamides, which may contain non-saltforming groups in the nucleus, with aliphatic, cycloaliphatic, araliphatic, heterocyclic, substituted aromatic, or aromatic condensed ring carboxylic acids or their functional derivatives. In a modification, the naphthyl-, anthryl-, or phenanthryl-sulphohalides, which may be substituted by non-saltforming groups, are reacted with salts of amides of aliphatic, cycloaliphatic, araliphatic, heterocyclic substituted aromatic, or aromatic condensed ring carboxylic acids. In examples: (1) N - (b 1 - naphthoyl) - b  - naphthalene sulphonamide is made by heating b -naphthalene sulphonamide with b -naphthalene carboxylic acid chloride in pyridine-in a similar reaction the a -naphthalene carboxylic acid chloride may be used instead of the b -naphthalene carboxylic acid chloride; (2) N-cinnamoyl-a -naphthalene sulphonamide is made by heating a -naphthalene sulphonamide with cinnamic acid chloide; (3) N-(g g g -trichlorocrotonyl) - a  - naphthalene sulphonamide is made by heating a -naphthalene sulphonamide and g g g -trichlorocrotonic acid chloride with aluminium chloride or copper powder in nitrobenzene; (4) N - (a  - phenyl - isovaleryl) - 4 - chloronaphthalene-2-sulphonamide is made by heating 4 - chloronaphthalene sulphochloride with the sodium salt of a -phenyl-isovaleric acid amide in xylene; (5) N-(a -naphthalenesulphonyl) - 1 - (p - chlorophenyl) - cyclopropane - 1 - carboxylic acid amide is made by heating a -naphthalene sulphonamide and 1-(p-chlorophenyl) - cyclopropane - 1 - carboxylic acid with phosphorus pentoxide in chlorobenzene- and in an analogous manner, N-(a -naphthalene - sulphonyl) - 1 - (31,41 - dimethylphenyl) - cyclopentane - 1 - carboxylic acid amide may be produced, and (6) N - (b 1-propylcinnamoyl) - b  - naphthalene-sulphonamide is made by heating b -naphthalene-sulphonamide and b -propyl-cinnamic acid with phosphorus pentachloride in nitrobenzene-and in an analogous manner N-(2,5-dichlorobenzoyl)-b -naphthalene sulphonamide may be produced.

Title: Means for counting documents
IPC: G06M9/00
Filed: 1952-11-07
Abstract: 717,467. Counting-apparatus. ATELIERS DE CONSTRUCTIONS ELECTRIQUES DE CHARLEROI. Nov. 7, 1952 [Nov. 10, 1951], No. 28085/52. Class 106 (1) Apparatus for counting bank-notes or other documents by means of a feeler 3 engaged with the stepped edges 2 of a stack of the documents, comprises a transducer 5 which regulates the value of an electric variable in correspondence . with the position of the feeler, an electronic impulse-generator 15 generating an impulse for each change in value of the variable and of amplitude proportional to the change, an electric selector device 16 which converts each impulse received into one or more impulses of constant amplitude according to the amplitude of the impulse received, and an electric totalizer 17 which registers the number of these latter impulses, this number being equal to the number of documents counted by the feeler. The apparatus correctly counts two- or more documents adhering and forming a single step since, in such event, the impulse transmitted by the generator 15 to the selector 16 is of correspondingly greater amplitude, and the selector 16 then transmits an appropriate number of separate impulses to the totalizer 17. The transducer 5 may be a potentiometer resistance whose wiper is mechanically linked with the fee'er 3 and adapted to apply a variable potential to the impulse generator. Alternatively, the transducer may be a variable capacitor of an oscillation generator. Mention is made of known resistance-capacity differentiating circuits as suitable for the impulse generator, and of electronic or other relay assemblies, regulated to respond at predetermined amplitudes, for the selector.

Title: Improvements in or relating to fuel systems for internal combustion engines and gas turbines
Inventor: BOOTH DOUGLAS GERHARD
IPC: F02C7/236
Filed: 1953-10-13
Abstract: 760,703. Fuel supply systems. PLESSEY CO., Ltd. Oct. 13, 1954 [Oct. 13, 1953], No. 28114/53. Class 7 (3). [Also in Groups XXVI and XXIX] In a fuel supply system having two or more pumps 26 .... 28 in parallel supplying fuel in excess of engine requirements and a by-pass 34 for returning excess fuel to the supply side 22, all the pumps except one are provided with a branch passage 36, 37 leading from the delivery side to the supply side 22 and having a servo-operated valve 38, 39, therein controlled by a flow-responsive valve 35 in the by-pass 34. Fuel is drawn from a tank 21 by three gear pumps 26 .... 28 in parallel which deliver through non-return valves 29 .... 31, to a metering device 32 from which excess fuel is returned to the low pressure side of the pumps through the by-pass 34 containing a spring- loaded flow responsive valve 35 having a flow restriction 12a therein. The branches 36, 37 are normally closed by valves 38, 39, actuated by spring-loaded pistons in cylinders 40, 41, connected to the pipe 34 through passages 44, 45 containing restrictions 46, 47. When the engine fuel requirements are high, e.g. at low altitude, the valve 35 is moved towards the right to open passages 43, 42 to prevent pressure build up in the cylinders 40, 41 whereby the valves 38, 39, are moved to the left to close the by-passes 36, 37. As the engine fuel requirements decrease, e.g. at increasing altitude, the increased flow through the by-pass 34 moves the valve 35 to the left until the passage 42 is blocked, whereupon pressure builds up in the cylinder 40 and the valve 38 is opened to by-pass the delivery of the pump 27 back to the supply side of the system. On further decrease in engine fuel requirements the valve 35 moves further to the left to block the passage 43 causing the valve 39 to open and by-pass the delivery of pump 28. If there is a further decrease, the valve 35 opens a by-pass 11a. A fuel system containing only two gear pumps in parallel is also described.

Title: Improvements in on-off recorders
IPC: B41J3/00
Filed: 1955-10-03
Abstract: 798,092. Recording-apparatus. ROBINSON & PARTNERS, Ltd., F. C., and ROBINSON, F. C. Dec. 18, 1956 [Oct. 3, 1955], No. 28134/55. Class 106 (4). [Also in Group XV] An on-off recorder for a machine in which a pen 15 is supported in contact with the metal coating of a chart 14 traversed therepast has a switch 26 controlled by the machine to apply voltage between the pen 15 and metal coating over periods determined by the operation of the machine. The recorder of Specification 729,663 is modified to use as its heat-sensitive chart, a backing material coated with a metal which will be removed by volatilization upon the application of a voltage of the order of 10-50 volts, e.g. cadmium or aluminium, the coating having a thickness of the order of 10-150 millimicrons. The chart is drawn from a supply roll 16 by a motor-driven roller 18 passing under a contact roller 27 receiving current through a brush 23 from a rectifier 22 fed from the secondary of a mains transformer 21. A series of pens 15 are arranged transversely of the chart and when a switch 26 under the control of a machine to be monitored is closed the associated pen will produce on the chart a trace e.g. <SP>1</SP>/ 16  inch wide. Screws are provided for varying the spring pressure of each pen against the chart and the pens may take the form of flat metal strips, brushes formed of a number of fine wires or preferably wheels which reduce the tendency for metal oxide to accumulate. During recording the metal is burnt away in advance of the pen which thus intermittently encounters non- conducting spots. At these times a capacitor 29 charges and serves to reduce the current required and also reduces electrical interference with radio equipment.

Abstract: 990,729. Transmission systems; stereophonic systems. ELECTRIC & MUSICAL INDUSTRIES Ltd. Aug. 9, 1961 [Aug. 16, 1960], No. 28265/60. Heading H4R. A signal transmission system comprises a first signal path and a second signal path for the transmission respectively of first and second signals occupying, at least in part, a common band of frequencies, a variable attenuator or other gain control device having bi-directional properties and common to said paths so as to operate on the first and second signals simultaneously, the gain control device being coupled into the paths by hybrid means whereby the first and second signals are fed through the gain control device in opposite directions, the hybrid means being arranged to minimize cross talk between the first and second signal paths, and the arrangement being such that the transfer in the first and second signal paths is varied in a similar manner in response to variation of the gain control device. A stereophonic system has two signal paths L, R (Fig. 1). Lefthand signals are fed into the input of amplifier 1 and right-hand signals are fed out from amplifier 2. These amplifiers 1, 2 are coupled to a hybrid type network comprising a tightly coupled centre tapped autotransformer 3 and a balancing resistor 4, the network in turn being connected to a balanced constant impedance attenuator 5, preferably of balanced T-type. Input amplifier 7 and output amplifier 6 are connected through a similar hybrid type network 8, 9 to the attenuator 5. Attenuator 5 imparts an equal degree of attenuation to signals passing in each direction therethrough. In a second embodiment (Fig. 2) one terminal of each of the amplifiers 1, 2, 6, 7 and one terminal of the attenuator 5, which is of the unbalanced T-type, are connected together and may be earthed. The hydrid means may be resistive networks 10, 11, 12 and 13, 14, 15 (Fig. 3), in which event the attenuator is preferably of the balanced T-type. Attenuation equalizers and other components required in both paths may also be included in the common path provided they are of the constant impedance type. The system may use sum and difference signals.
