Patent GB-1118049-A (GB)
Title: Hydropneumatic cable tensioner
Inventor: PRUD HOMME JOHN WORSELY
IPC: B66D3/18
Filed: 1967-02-07
Abstract: 1,118,049. Dashpots. RUCKER CO. 7 Feb., No. 5882/67. Heading F2S. [Also in Division B8] A hydropneumatic cable tensioner comprises a piston 16 having a piston rod 17 carrying a sheave block and slidable in a cylinder 12 carrying a sheave block, the cable being reeved around the sheaves of the two blocks such that as the piston moves outwardly from the cylinder, the cable is tensioned. Pressurized air is supplied to the cylinder at the end 31 and maintains the cable under tension. Oil is supplied from a reservoir 38 to the cylinder at the end from which the piston rod extends. The oil in the reservoir is maintained under pressure by feeding pressurized air from the cylinder at 51 to the reservoir via a pressure-reducing valve 53. Oil enters the cylinder 12 through two ports 73, 48, one of which is closed by the piston passing over it during extension and one of which is always open, the latter port 48 being fed via a non-return valve 62 around which a variable-flow valve 64 is shunted. During normal operation, the cable is tensioned by the air in the cylinder. With a sudden release of load in the cable e.g. cable breakage, the piston tends to extend rapidly and the oil damps down this motion. A conical-shaped surface 72 of the piston passing the first said oil port 73 gradually restricts the outflow of oil therethrough and the variable flow valve 64 restricts the oil flow out of the second said port 48. A sensing mechanism coupled to the piston and cylinder indicates their relative positions. In the embodiment of Fig. 6 (not shown) the oil reservoir is coaxially mounted around the cylinder.

Abstract: 271,942. Marks, E. C. R., (Du Pont de Nemours & Co., E. 1.). March 2, 1926. Anthraquinonehydroazines. - Indanthrone is produced by the action of fused caustic alkali or a mixture of alkalies upon 2-aminoanthraquinone in the presence of an oxidizing agent and an organic alcoholate or phenolate, the latter being in less amount than the free caustic alkali present. According to examples, 2-aminoanthraquinone is fused with caustic potash, sodium chlorate, and sodium ethylate or butylate. Sodium methylate, phenolate, and cresolate are also specified for use in place of sodium ethylate and potassium nitrate as oxidizing agent in place of potassium chlorate.

Abstract: 1301923 Timing apparatus NORTH AMERICAN PHILIPS CORP 9 Feb 1970 [14 Feb 1969] 6037/70 Headings G4A and G4H An electrical timing apparatus comprises a first counter comprising a cascaded set of bistables 33-43 in which a count is set by gating the output of oscillator 11 to the counter for a period of time equal to a standard interval, a second cascaded chain of bi-stables 17-27 to which the output of the oscillator 11 is connected for the period of time being measured, a comparison circuit comprising a number of individual comparators 46-56 connected between corresponding bi-stables in the two chains and operative to generate a first signal when the counts in the two chains are equal and a second signal at the end of the period of time being measured, and a discrepancy circuit connected to the bi-stables 33-43 for measuring the difference if any between the standard interval and the time being measured as a percentage of the standard interval.  Two embodiments are described. In the first (Fig. 1) the discrepancy circuit consists of a number of transistors 88-98 and associated capacitors 77-87, the capacitance of each of which is equal to twice that of its predecessor. Each transistor is connected to a corresponding bi-stable in the chain 33-43 so that the time constant of the circuit formed by the connected capacitors is proportional to the standard interval. When the standard or measured interval ends (whichever is first) the capacitors are charged to generate a ramp waveform. A threshold circuit may be provided to respond to a given voltage on the ramp to indicate that the discrepancy between the standard and measured interval is in excess of, say, 10% of the standard interval. An indicator circuit may be provided with three lamps indicating that the measured interval is smaller than, longer than or the same as the standard interval. In the second embodiment, Fig. 5 (not shown), a third counter consisting of a cascaded chain of bi-stables is connected to the chain 33-43 through a number of comparators similar to the comparators 46-56. Pulses, from a highfrequency generator, having a repetition rate N times that of pulses from the generator 11 are gated to this third counter during the discrepancy interval. The device may be used for example to compare the time taken by a piston in an injection moulding machine to complete one cycle, i.e. to push a quantity of material into a die and return to the starting point for fresh material. The standard interval stored in the first counter, bi-stables 33-43, may be modified or left constant as desired after each comparison. The Specification describes in some detail the circuit arrangements giving the voltage levels corresponding to the various stages in the operation of the device.

Abstract: 439,165. Heels for boots and shoes. HEELITE PROPRIETARY, Ltd., 193, High Street, Prahran, Victoria, Australia. Feb. 27, 1934, No. 6334. Convention date, Oct. 9, 1933. [A Specification was laid open to inspection under Sect. 91 of the Acts, Sept. 8, 1934.] [Class 17 (ii)] Hollow moulded heels are attached by a substantially central threaded member or rivet which ties the heel to the shoe shank, a number of guide pins being formed integral with or attached to the heel around the seat to engage holes in the shoe shank to locate the heel in position. The heel may be of a phenolic resin compound or synthetic resin or glass, and is coloured to harmonize with the shoe upper. A metal plate may be provided in the shank of the shoe to receive the head of the central member and the guide pins, or such member may be formed integral with the plate. Alternatively, the insole may be thickened or a thick strip of soft material may be placed under the insole over the central member. As shown, the central member 35 which ties the heel 33 to the shank 28 of the shoe is located in position by guide pins 34 on the heel which register with and engage holes in the shank and insole. These holes may be reinforced by means of eyelets. The member 35 is screwed into a nut 49 in a recess 36 in a central pillar 35a in the heel, and this same nut is engaged by one of the screws 38 which attaches the heel lift. Other screws 32<a> may hold the lift against rotation. The lift may be stepped as shown at 30<a> to provide a greater thickness of material where the wear occurs. In other constructions, the central member screws at its lower end into a nut recessed into the heel near the lower end, or into the internally threaded end of a tubular member which extends upwards from a recess in the lower end of the heel. Alternatively, the member may be passed upwards into an internally screwed sleeve projecting from a metal plate in the heel end of the shoe, or it may be in bifurcated rivet form and turned over at its upper or its lower end. The heel tread may be secured by nails &c. to a plug inserted as by screwing in a cavity in the lower end of the heel. The Specification as open to inspection under Sect. 91 comprises also hollow heels of moulded material secured by a series of screws engaging nuts in recesses in the heel or in threaded apertures in the heel or a pillar therein, or alternatively a series of pins or bifurcated rivets may be moulded with the heel around the periphery of its upper face for securing the heel to the shoe. This subjectmatter does not appear in the Specification as accepted.

[Classes 39 (i) and 40 (v)] An electronic distributer comprises a cathode surrounded by a number of anodes and the electrons are concentrated into a beam and focused on the anodes in succession by a rotating magnetic field; the beam may be suppressed on one side of the cathode by an electrostatic field rotating in synchronism with the magnetic field. The anodes 22 surrounding the cathode 19 are separated by screens 26 which may serve as electrodes for concentrating the beam on to one side of the cathode as before mentioned. The rotating field may be produced by a rotating magnet or by two-phase or polyphase currents in windings like those of an induction motor ; a single-phase source may be used with phase-splitting capacities. The current may be modulated by a grid surrounding the cathode. Fig. 12 shows the invention applied to multiplex telegraphy. The distributers are furnished with slotted accelerator electrodes 41. The beam in the sending distributer is modulated by slotted electrodes 43 opposite to the anodes 22 and connected to the input sources.
