Title: Gaseous discharge tube circuits
Inventor: O'DELL DOUGLAS THOMAS
IPC: H03K3/55
Filed: 1951-07-18
Abstract: 711,431. Pulse generating circuits. NATIONAL RESEARCH DEVELOPMENT CORPORATION July 18, 1952 [July 18, 1951], No. 17060/51. Class 40 (6) A pulse generator comprises a number of grid controlled gas discharge tubes which have individual discharge networks and are connected to a common load through individual delay networks each of which has a delay at least slightly greater than the duration of the triggering pulse applied to the gas-discharge tube. The Figure shows a circuit for generating a very high voltage pulse across a load R by means of the delayed parallel connection of thyratrons V4-V7. A resonantly charged low-power modulator comprising a thyratron V3, discharge netwrok N3 and input transformer T1 generates a steeply rising triggering pulse simultaneously at the grids of valves V4-V7. The valves fire and discharge networks N4-N7 via delay networks D4-D7 through the load R, the networks N4-N7 having been charged from a high voltage supply via rectifiers and isolating chokes CH2. The simultaneous firing of valves V4-V7 is aided by connecting them to the discharge networks N4-N7 through a balancing transformer unit T2 the windings of which are very tightly coupled, for example by using iron-dust cores so that if the current in one thyratron is lagging the current rise in all the other valves will be slowed up and its rise of current will itself be assisted by all of the other valves. The delay times of the networks D4-D7 are accurately matched and are each at least slightly greater than the duration of the triggering pulse applied from thyratron V3 so that each valve discharges into a delay network of the same and constant impedance so that mismatch is avoided if the firing of any valve is delayed. The current transformers T3-T7 enable the operation of the circuit to be monitored by means of a cathode ray oscilloscope.

Patent GB-1520604-A (GB)
Title: Time-setting and displaying mode control circuit for an electronic timepiece
IPC: G04G5/00
Filed: 1976-04-28
Abstract: 1520604 Electronic timepieces TOKYO SHIBAURA ELECTRIC CO Ltd 28 April 1976 [28 April 1975] 17237/76 Heading G3T An electronic timepiece has a time setting and displaying mode control circuit 7, Fig. 1, which supplies display mode signals to a decoder 8 to display the content of selected counters 2-6, and which to effect time correction supplies setting mode signals SZ, MIS, HS, DS, MOS to a selected one of the counters to correct only that counter. The circuit 7 includes two switches to selectively cause one of the time setting or time display mode signals in accordance with the number of times the switches are each successively operated and in dependence upon whether a switch is maintained closed for two or more seconds. Detection circuits detect operation of respective switches and respective ring counters memorize the state thereof to effect through logic circuits the selected mode. In Figs. 2A, 2B, a detection circuit 10 comprising shift registeres 11-13 and 15,16 detects the state of switch SW1. Likewise a detection circuit 50 comprising shift registers 51- 53 and 55, 56 detects the state of SW2. A pulse is produced from NOR gate 14 each time SW1 is depressed. Similarly a pulse is produced from NOR gate 54 each time SW2 is depressed. A NOR gate 40 produces a pulse when SW1 is maintained closed for two or more seconds; a NOR gate 59 passes a 1HZ signal when SW2 is maintained closed for two or more seconds. A time setting mode circuit 30 includes a ring counter comprising shift registers 31-34 and a NOR gate 35. A time displaying mode circuit 60 includes a ring counter formed by shift registers 61, 62 and a NOR gate 63. Setting Mode Successive depressions of switch SW 1 shifts the content of registers 31-34 so that a logic "1" appears at the output of each register in turn and is supplied as an hour, minute, month or date setting mode signal to respective counters 4, 3, 6, 5. During time setting, the ring counter 61, 62 is reset by the output of NOR gate 35, and, if SW2 is depressed for two or more seconds, a 1HZ pulse train is passed by an AND gate 58 and via NOR gates 59, 43, AND gates 36, 37, 38 or 39 to counter 4, 3, 6 or 5 thereby to advance the respective counter. Display Mode If SW1 is maintained closed for two or more seconds, the shift registers 31-34 will be reset via AND 17 or NOR gate 40, irrespective of the mode pertaining, and the hours/minutes display mode will be established. If SW2 is now depressed, the output from AND gate 42 shifts the content of registers 61, 62 so that a "1" output from 61 is passed via AND gate 65 to decoder 8 to cause a month/date display. If SW2 is depressed again the output from 62 via AND gate 66 causes a seconds display. A further depression of SW2 results in change-over to the hours/minutes display.

Abstract: 819,923. Textile spinning machines. T.M.M. (RESEARCH) Ltd. May 22. 1957 [June 4, 1956], No. 17240/56. Class 120(2) A single-sided ring spinning machine with means for assisting delivery of slivers from containers at floor level by an overhead path to drafting machanism is provided with a double row of staggered spindles. Slivers are fed from cans 10, 11 behind the machine and pass over rollers 13 driven by chains from the shaft of the bottom back roller 17 of the drafting apparatus, which may be as disclosed in Specification 734,978. From the front drafting rollers, yarns pass through eyelets in wire feeler members 36 of a stop motion. Should a yarn break, the corresponding member 36 will fall to contact an electrical conductor 40 to stop the machine. When starting the machine, the travellers are temporarily retarded by manually pivoting upstanding brushes 43, Fig. 5, into the paths of the travellers. To prevent the yarns lashing against each other, the spindles of the front row are each surrounded by a cylindrical shield 29 provided with a door 29 giving access to the interior of the shield. Between the spindles of the rear row, upstanding plates 31 are arranged and above these spindles are balloon control rings 32. Drive to the spindles is by a belt 22 that has two runs extending throughout the length of the spindle rail and is guided by pulleys 25 intermediately of the spindles. The belt passes over the driving pulley of an electric motor at one end of the spindle rail and over an adjustable tensioning pulley at the other end. According to the Provisional Specification, the spindles are driven through individual belts from intergeared parallel shafts extending longitudinally of the machine.
Patent GB-735345-A (GB)
Title: Extrusion process
Inventor: LIDDELL WILLIAM
IPC: D01D4/06
Filed: 1952-07-09
Abstract: In melt-spinning or extrusion apparatus in which molten material is passed through a filter pack, the plate supporting the pack has a number of grooves, preferably intersecting on the surface facing the pack, which lead to one or more apertures in the supporting plate through which molten material passes to the spinneret or extrusion die.  The molten material may be a linear condensation polymer such as polyethylene terephthalate or nylon. The plate may be provided with heating means and may also have grooves on the side facing the spinneret or die.  A coarse wire gauze may be located between a fine wire gauze supporting the filter pack and the plate.  The grooves on the surface of the plate facing the filter pack may be arranged at right angles, concentrically or radially.  In the example polyethylene terephthalate yarn is melt-spun using an apparatus in which a plate provided with grooves 1/16 inch wide, 1/16 inch deep and 1/8 inch apart is located below the sand pack assembly so that the grooved face of the plate directly supports the bottom 50-mesh gauze of the sand-retaining gauze assembly. The intersections of the grooves each lead to an aperture drilled through the entire thickness of the plate, and these apertures communicate with the holes in the spinneret.  The rate of pressure-rise with time is one-fifth of that found when an ungrooved plate is used.

Title: Improvements in or relating to blade ring assemblies for axial flow compressors or turbines
IPC: F01D5/18
Filed: 1952-07-10
Abstract: 749,577. Axial flow turbines and compressors. DE HAVILLAND ENGINE CO., Ltd., HALFORD, F. B., and CLARKE, G. F. Sept. 21, 1953 [July 10, 1952], No. 17416/52. Classes 110(1) and 110(3) A blade ring assembly for an axial flow compressor or turbine comprises concentric outer and inner blade supporting rings to which the blades are pivotally connected at both ends in such a manner that the straight lines through the axes of the pivots in the plane of the blade ring are tangential to a circle concentric with the outer and inner blade supporting rings. Variations in the relative diameters of the supporting rings or the lengths of the blades or both due to thermal expansion or contraction is thus accommodated by limited relative rotation of the supporting rings about their common axis. The blade ring shown comprises an outer supporting ring C, which may be formed integral or separate from the turbine casing C<SP>1</SP>, and an inner supporting ring formed of two parts D, D<SP>1</SP> secured together by a series of bolts F'. A series of blades E, having an outer end portion E<SP>1</SP> formed with a pair of widely spaced lugs E<SP>2</SP> and an inner end portion E' in the form of a single lug are pivoted by bolts F, F<SP>1</SP> to the rings C, D, D'. The bolts F' pass through an eccentric bore in the bushing F<SP>2</SP> which makes a free but close fit in a bore in the lug E<SP>2</SP>. When the bolts F<SP>1</SP> are tightened the bushes F' are clamped between the parts D, D' and prevented from rotation. This arrangement allows for small inaccuracies in manufacture to be accommodated. The inner supporting rings D, D<SP>1</SP> is provided with parts D<SP>2</SP>, D<SP>3</SP> and D<SP>4</SP> which form guides for the gas flow between adjacent blade rows and between adjacent blades of the blade ring. Similarly shrouds C<SP>2</SP> may be associated with the outer supporting ring C. In a modification, the blades E are made hollow and the parts E<SP>1</SP> and E<SP>3</SP> are formed as separate members attached to the ends of the blades E. The parts E<SP>1</SP>, E' have passages through which cooling air is supplied to and withdrawn from the blades. In this arrangement, a sealing member is carried by the inner supporting ring which co-operates with a surface on the rotor. Specification 749,578 is referred to.

Title: Improvements in or relating to the projection of televised images
IPC: H04N5/74
Filed: 1954-06-14
Abstract: 786,553. Television; light modulating. SOC. GENERALE D'ELECTRONIQUE. June 14, 1954 [June 15, 1953 ; May 26, 1954], No. 17452/54. Class 40 (3). An arrangement for reproducing television pictures employs a light modulating device comprising a deformable reflecting metallic sheet F supported at a short distance from an insulating support I (consisting of the end wall of a cathode-ray tube T) by means of a plurality of spaced elements H, the arrangement being such that when the sheet is scanned by an electron beam modulated by the television signals, the resulting deformations produced by electrostatic attraction between the sheet and the support I modulate, in co-operation with the grids G1, G2 of a Toeplar optical system, light from a local source S and thereby project an image corresponding to the modulating signals on to screen E. The sheet F may be either flat (Fig. 2), or undulating, as shown in Fig. 6 (the elements H being castellated in this case) in the absence of scanning the electron beam being modulated by signals having maximum intensity representative of picture white in the former and representative of picture black in the latter case. In alternative constructions, the sheet F may be formed with alternate thick and thin strip portions (Fig. 3, not shown) ; the spacing elements H may each be formed from two members, one being transparent and the other opaque and reflecting (Fig. 5, not shown), and the whole device may be made spherical instead of plane so that it acts as a concave mirror which directly produces an image of the grid G1 on the grid G2, thus enabling the lens 01 to be dispensed with (Fig. 7, not shown). Specifications 684,706, 701,543 and 776,665, [Group XL (a)], are referred to.

Abstract: 409,151. Conductors. McKAY, R. F., Fort Dunlop, Birmingham.-(Inter. national Latex Processes, Ltd. ; 10, Lefebvre Street, St. Peter's Port, Guernsey.) June 20, 1933, No. 17513. [Class 36.] To improve the insulating and waterproof properties of the rubber insulation of a conductor of the kind insulated by treatment with aqueous dispersions of rubber, insoluble matter is incorporated in the rubber insulation, such matter being formed by rendering insoluble water-soluble ingredients, such as soaps, which are normally present in, or which have been added to, the aqueous dispersion. The aqueous dispersions may include natural latex, artificial dispersion or purified latex and may contain fillers as well as compounding and vulcanizing ingredients. The dispersion may be used in a prevulcanized form. In one embodiment, a conductor covered with fibrous material, such as paper, is passed through an aqueous dispersion of rubber and then through a 4 per cent solution of sodium or ammonium oleate and after drying is passed through a solution containing a soluble metal salt which is adapted to render insoluble the water-soluble ingredients of the coated conductor. The soluble metallic salt may be an acetate of, for instance, magnesium or cadmium. In another embodiment, a fibre covered conductor is passed through a solution of a water-soluble metal salt capable of forming insoluble soaps with creamed or centrifuged latex through which the conductor is then passed. A thick insulation is obtained by repeated passages of the conductor through the metallic salt solution and latex. Specifications 464/63, [Class 70], and 411,685 are referred to.
