Title: Improvements in or relating to hydrostatic bearing systems
IPC: F16C32/06
Filed: 1958-05-09
Abstract: 876,993. Fluid bearings. ASKANIAWERKE A.G. May 9, 1958 [May 10, 1957], No. 14967/58. Class 12 (1). In a hydrostatic precision bearing system for maintaining a constant clearance between the spherical bearing members 9, 10 of a heavy astronomic reflection telescope and socket supports 13, 14 a pump 24 draws lubricant from a sump 26 and delivers it to the bearings through restrictor assemblies 27, 28 the ratio of the pressures at the input and output ends of each of which is maintained substantially constant, e.g. by adjustment of the weight 41 of a weight loaded valve 40 which forms a by-pass for the pump and regulates the lubricant pressure at the input ends of the restrictors. Each restrictor 27, 28 comprises a fixed capillary passage 27<SP>1</SP>, 28<SP>1</SP> in series with a number of capillary passages 27<SP>11</SP>, 28<SP>11</SP> which can also be varied to produce the required pressure ratio, a surge tank 32 with an air cushion filtering unwanted pressure surges produced by the pump 24. A surge tank may also be introduced into a common line between the two restrictor zones 27, 28 each side of which are arranged pressure gauges 29, 30 and 31. In the system shown in Fig. 3 where 50 represents a bearing zone, 59 the restrictor, and 52 the pump, the restrictor is shunted by a device 55 which detects variations in pressure across the restrictor and automatically makes compensating adjustments to the position of the weight 41 of the valve 40. In a further modification, Fig. 4, compressed air is supplied through a nozzle 62 to a pneumatic sensing unit 60 having an air jet nozzle directed against the top of the bearing sphere 10. The pressure of the air head of the nozzle 61 is transmitted through a line 63 to control a regulator 64 modifying the positions of a by-pass valve 65 across the pump 66.

Title: Improvements in fire alarm systems of the automatic type
IPC: H04M11/04
Filed: 1937-06-01
Abstract: 500,037. Automatic exchange systems. SCOTT, H. D., SMALL, F. M., HAIT, H. L., and TAYLOR, R. June 1, 1937, No. 15230. [Class 40 (iv)] [Also in Group XXXVIII] Apparatus at a telephone subscriber's substation for automatically transmitting a fire alarm comprises a rotary drum set into motion by a thermostat and carrying on its periphery helicallyarranged projections which effect the transmission of the necessary impulses first to select the fire station through an automatic exchange and then to operate an indicator at the fire station to identify the calling substation, the impulses being produced at a pair of contacts advanced by a feed screw in synchronism with the rotation of the drum. In the construction shown, Figs. 2, 3, 7, the closure of contacts 16 by a thermostat operates a magnet 15 which withdraws a detent from a ring 40 to set the spring-driven gear-train in motion and closes contacts 26 to operate a local alarm 33 from the supply mains 28. The impulsing springs 20 are mounted on a lever 42 pivotally supported on a carriage 42b which slides on guide rods 42c, the lever 42 having a threaded portion. 42e engaging a feed screw 42d driven from the gear-train. A spring 42f normally holds the lever 42 and feed screw in engagement but the pivotal connection to the carriage permits the drive to be disconnected and the contacts to be moved out of the path of the projections 44 during the return movement. The drum 35 carries four complete sets of projections, each set providing, for the transmission of the fire-station number followed by the station-identifying digits, the sets being separated by long projections 51 which open the circuit for a sufficient time to effect release at the exchange. At the end of the fourth transmission, a further long projection 52 maintains the circuit open and a catch 41 co-operates with armature extension 24a to stop the drum. At the fire station, Fig. 10, ringing current operates relay 62 to complete a circuit for relay 70 which locks over a restoring button 77 and operates all alarm 110. The station-identifying impulses are then repeated by relay 84 to set a selector 87 which picla out a circuit for operating a relay 98 and an identifying lamp 101 individual to. the calling substation. Relay 98 operates common relay 100 which lights a pilot lamp 104.

Title: Improvements in and relating to wireless telegraphy and telephony
IPC: H04B7/12
Filed: 1926-06-18
Abstract: 253,934. Marconi's Wireless Telegraph Co., Ltd., (Assignees of Peterson, H. 0.). June 19, 1925, [Convention date]. Fading, preventing; atmospherics and undesired signals, eliminating; heterodyne receiving systems.-In order to minimize static, interference, and fading effects, particularly when the latter is due to interference between the "free" and earthbound components of' short-wave radiation, a series of spaced aerials 1, 2, 3 are linked together so as to produce an improved average of signal strength in a common receiver 23. In order to overcome the difficulty of directly combining the received waves, owing to phase-difference and attenuation effects, the received energy is modulated at audio frequency over a common transmission line 13 and separate coupling coils 7, 10 and 8, 11 and 9, 12. The corresponding audio frequencies appear in the output circuits 18, 19, 20, and therefore in the receiver 23, only when the incoming signals affect each individual' aerial, the resultant effect as heard in the phones 23 being independent of the phase-relation of thereceived high-frequency energy. Alternatively as shown in Fig. 3, the received signals are modulated by a sub-modulated high-frequency oscillation derived from an independent valve generator 40 coupled to the valve 38 and fed with an audio frequency through a coil 42. The supersonic frequency from the modulator 38 is amplified at 44, and the audio frequency note detected at 46 and fed to the common output line 47. An arrangement is also described in which a modulated high frequency is generated at a central station and is fed to the individual receiving aerials over a common transmission line, which also serves to return the detected low-frequency note to the receiving instrument at the central station. The receiving aerials are spaced apart by a distance of from one to two wave-lengths, or more, according to local " fading " conditions.

Title: Improvements in or relating to stepping motors
IPC: H02K16/00
Filed: 1961-04-28
Abstract: 979,172. Counters. K. EHRAT. April 28, 1961 [May 2, 1960], No. 15515/61. Heading G4D. [Also in Division H2] A step by step motor for driving a counter comprises a transversely magnetized rotor with the magnetic axis of section 1a at right angles to that of 1b each co-operating with its own wound stator J 1 , J 2  and driving counter 7 through gearing 4, 5. Pulses, which may be derived from an electronic ring counter Fig. 9 (not shown) or other means, are applied alternately to each stator winding and cause the rotor to rotate through 90 degrees for each pulse. Other modifications involving change s in the shape of both the stator and rotor, Figs. 6, 7,11,12 (not shown) are described and include the case when the rotor sections are joined by gearing or each rotor section drives a common counter shaft through gearing, Figs. 15, 16 (not shown). Also described are modifications where the rotor is rotated through 120 degrees and 180 degrees for each pulse i.e. 3-pulse and 2-pulse systems. A two pulse system is obtained by having a single magnet yoke with bifurcated polepieces each co-operating with one section of the rotor, one polepiece having a shading winding on it, Fig. 17 (not shown), or by having two stator windings on each yoke and supplying them from a bi - stable trigger circuit, Fig. 21 (not shown). If 3-pulse operation is required the rotor magnetic axes are displaced by 120 degrees from each other in each section and the stator may comprise a three limbed E-shaped yoke, Fig. 29 (not shown). In a practical application only one half of the stator yoke need be wound and the rotor sections, although transversely magnetized along different axes, may form a continuous uniform rod Fig. 33 (not shown).

Title: Improvements in or relating to electric switches with arc extinction by self-generated vapour
IPC: F16L21/02
Filed: 1930-05-21
Abstract: 354,866. High-tension switches. SIEMENS-SCHUCKERTWERKE AKT.- GES., Siemensstadt, Berlin. May 21, 1930, No. 15678. Convention date, July 16,1929. [Class 38 (v).] In an " expansion " switch as described in Specification 354,890, with a vapour chamber having an upwardly - directed conduit 3 for the movable switch pin 4, the diameter of the conduit is at least 4 mm. greater than the diameter of the switch line. In the construction shown, the hollow cylindrical contact 5 in the explosion chamber 1 which contains liquid (for example, water) communicates through the pipe 7 with an auxiliary air vessel 6 which relieves the pressure in the chamber 1. This vessel is furnished with a valve 8 held down by a spring 9. If small powers are being dealt with by the switch the pressure produced does not raise the valve. For high powers, when the pressure necessary to cause effective arc-extinction (on expansion) has been reached by the action of the arc drawn between the contacts 4, 5, the valve is opened and excess pressure relieved. Both chambers contain liquid and the flow between them passes over the arc-foot and assists to extinguish the arc. After the break, the liquid levels adjust themselves by means of the small passages 10, 11. Any loss is made up for by the inverted bottle device 12.

Abstract: 1,134,582. Purification of sulpholane-type solvents. SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ N.V. 6 April, 1967, No. 15801/67. Heading C2C. Sulpholane-type solvents containing corrosive contaminants are purified by contact with an aqueous solution containing an alkaline compound and with an alkali-resistant liquid, which is sparingly soluble in water and which dissolves the sulpholane-type solvent more readily than water, separating a solvent phase containing alkali-resistant liquid from the aqueous phase and subsequently recovering the sulpholane-type solvent from the solvent phase. The preferred alkali-resistant liquids are hydrocarbons, e.g. benzene. The aqueous alkaline solution is suitably provided by dilute aqueous solution of an alkali or alkaline earth metal salt, e.g. NaOH. The aqueous alkaline solution preferably also contains a neutral salt, e.g. NaC1, to counteract the formation of emulsions and facilitate gravity separation of the aqueous and solvent phases. It is preferred to separate the sulpholane from the solvent phase by distillation. The process is illustrated by reference to schematic flow diagrams (not shown).

Title: Improvements in Submarine Destroying Bombs.
Inventor: STEINMETZ JOSEPH ALLISON
IPC: F42B21/00
Filed: 1917-11-01
Abstract: 119,136. Steinmetz, J. A. Nov. 1, 1917. Mines, marine.-Relates to bombs connected by a line to a float to explode the bomb when it sinks to a given depth under water for the destruction of submarine vessels. According to the invention, the line is arranged so that its length can be quickly varied, and means are added to explode the bomb by contact with the submarine vessel. As shown, the line H is connected to a spring- striker J on the bomb, so that the striker is cocked by the pull of the float I until a slip-lock joint K in the striker is withdrawn from its socket, when the striker is released and fires the bomb A. Lengths B, C, D, E of line are coiled around the bomb, and any of these may be added to the line H to vary the depth at which explosion shall take place. Devices D distinguishable by the eye or the hand are provided. on these lengths of line to indicate the corresponding depths. If the bomb strikes the submarine vessel before the appointed depth, explosion is caused by a pin P which is driven against a detonator Q by contact with the submarine vessel, the bomb being weighted at the end 0 where the pin P is, in order to ensure that the bomb shall sink with this end downwards. The pin P is normally protected by a screw cap T which is removed before the bomb is dropped. The float is normally slipped on the other end of the bomb and comes off when the bomb is dropped into the water.
