Title: Improvements in methods of, and apparatus for, joining together stranded wire cables or for anchoring the ends thereof
IPC: H01R4/50
Filed: 1929-10-29
Abstract: 340,081. Highfield, J. S. Oct. 29, 1929. Sleeve couplings.-The inner strands 5, e.g., of steel, of a cable are clamped between an externally conical member 6 and an internally conical member 8, the tension being transmitted from the latter through a distance piece 11 to a split cone 9 that surrounds the outer strands, e.g., of copper or aluminium, and fits within the conical end of the connecting sleeve 3, 4. The strands 5 are bent over the rounded end 7 of the member 6, passed in turn through a slot 13 in the member 8 and then gripped by tightening a nut 12. In a modification, the strands 5 may be divergent, lying between a roughened cone and an outer internally coned member, the cone and member being forced together by a nut. The distance piece 11 may be replaced by a series of loose interfitting conical members 20, 21, Fig. 2, the inner member 20 being split and fitting to the outer strands of the cable, and the outer member 21 being solid and abutting against the inner cone of the adjacent pair. Some of the cones 20 need not be split. For a jumper lead 22 a series of conical members 24, 25 tightened by a nut 26 may be used. The cable ends may be painted with a waterproof composition or the sleeve may be filled with oil. According to one Provisional Specification the various layers of the cable may each be secured by a clamp similar to the clamp 6, 8, the outer members of which abut against shoulders in the sleeve 4 or against one another.

Filed: 1967-07-19
Abstract: 1,181,867. Analog/digital converters. SOLARTRON ELECTRONIC GROUP Ltd. 27 May, 1968 [19 July, 1967], No. 33126/67. Heading G4H. After a first analog/digital converter 12 has been balanced the difference signal from its comparator, which may represent for example the error due to overshoot of amplifier 14, is fed to a second analog/digital converter, a threshold circuit 21 in which enables a pulse generator 22 pulsing a counter 23 until a ramp signal fed back to the first analog/digital converter reduces the error signal substantially to zero. In the embodiment described logic circuitry 16 in the first converter 12 enables a transistor switch 19 so that the error signal after amplification is fed to the threshold circuit 21. The pulse generator 22 additionally controls a pump 24 and capacitor 25 to generate the ramp signal. When the second converter is balanced counter 23 is counted down to zero, the lowest stages of the counter of the first converter being simultaneously counted up to correct the error.

Title: Method of and apparatus for preparing batches of a suspension of powdery substance in liquid
IPC: B01F15/02
Filed: 1961-09-15
Abstract: 939,327. Mixing appliances. H. BORS. Sept. 15, 1961, No. 33227/61. Class 86. In a method of preparing a suspension of a powdery material, e.g. cement in water, the powder is measured by admitting a metered quantity of the liquid to the mixing tank before or simultaneously with the powder, and measuring the quantity of powder indirectly by measuring a property (e.g. volume or flow resistance) of the mix. As shown a known volume of water is supplied through a pipe 35, valve 6 and flowmeter 5 to a circulation pipe 36 and is expelled through a nozzle 17 into the cylindrical tank 1, while cement from the silo 15 is induced into the pipe 36 at 4 by injector action aided by gravity. The mixture in the tank is circulated through pipe 36 by the pump 19. There are low and high level electrode dipsticks 12, 13; the adjustable high level dipstick 13 acts to close the cement inflow valve 7 when the predetermined maximum mix level 23 has been reached. Emptying is initiated manually or by a signal from other apparatus (e.g. an associated concrete mixer to which the mixing apparatus may deliver) by closing the valve 8 and opening the valve 9 (the valves being interconnected), when the mix is discharged by pump 19 through pipe 35 ; the electrode 12 causes the valves 8, 9 to change over again when the minimum level 21 is reached. Instead of the arrangement of dipsticks and liquid levels, cement may be added until the mix reaches a predetermined viscosity as detected by a spring- loaded flap valve in the circulating system. An additional liquid, e.g. plasticizer, may be injected at 28 by a pump 25 and pipe 27 from a container 26 provided with a float and tell-tale rod. The dipstick 13 may have an external scale 22 and the apparatus may be arranged to recycle automatically on emptying to the low level 21. Mixing may be assisted by vibrating the mix by means of a liquid whistle, or baffle rings in the pump. The dipstick electrodes may be replaced by float switches or electronic means. The cement in silo 15 may be fluidized. In another embodiment, see Fig. 2 (not shown), the circulating and emptying pump is external to the apparatus, which is placed above a concrete mixer to which it delivers by simultaneous pump and gravity action. A single dipstick electrode gives a continuous reading on an indicator having limit switches which control the valves.

Title: Improvements in or relating to refrigerating apparatus
IPC: A24C5/58
Filed: 1934-11-19
Abstract: 435,297. Refrigerating. HENNIG, J., 82, Eupenerstrasse, Aachen, Germany. Nov. 19, 1934, No. 33309. Convention date, Nov. 18, 1933. [Class 29] In a differential pressure floatmeter for measuring the output of a refrigerating machine the restricted orifice 1 for producing the differential pressure is placed at the top of the instrument and the entrance 5 to the portion containing the indicating float is placed low down. Bubbles of gas due to insufficient filling of the refrigerating machine cannot thus accumulate in the floatmeter and all pass through the orifice 1 causing an oscillation of the float which gives a warning of insufficient filling of the apparatus. A throttle member 4 actuated by a handle 3 is provided to regulate the aperture 1. In order to prevent the presence of bubbles of refrigerant gas in the liquid the refrigerant is cooled before it enters the instrument. This may be effected by leading a portion of the refrigerant through an expansion valve to a jacket surrounding the conduit carrying the main refrigerant stream.

Filed: 1972-05-06
Abstract: 1433869 Servo-positioning ALFRED HERBERT Ltd 1 May 1973 [6 May 1972] 33654/75 Divided out of 1433868 Heading G3N In a servo-control system, altering the position of a controlled member (tool of machine tool) towards a demanded position, increments of motion during a member acceleration phase are counted twice, those during member motion at constant speed being counted once, deceleration; at a rate equal in magnitude to the acceleration; to the demanded position being initiated when the total counted number of increments equals a stored value equal to the number of increments between an initial, and the demanded, member positions. Control arrangement, Fig. 1. Servo unit 30 operates either in acceleration, or deceleration, modes, of mutually equal magnitude, or in a constant speed mode, AND gate 72 being opened for the acceleration mode, AND gate 74 for the constant speed mode. Upon any change in the demand signal, the error signal immediately after such change is gated in inverted form into counter 60 whose content thus represents in negative form the distance to go to the demanded position. In the acceleration mode of the servo unit 30, in virtue of multiplier 76, counter 60 is counted up at twice the rate per unit increment of actual motion in comparison with the rate for the constant speed mode of the unit 30. When the content of counter 60 reaches zero, the unit 30 is switched to the ramp down mode, at the required distance in advance of the required destination position in view of the equal magnitude of the acceleration and deceleration. For two, or three dimensional member motion, a single counter is set initially with its content representing the sum of the moduli of movement increments for each of the axes, and the position transducer of a servosystem corresponding to each dimension provides signals changing the counter content. All servos switch to the deceleration mode when the counter content reaches zero. Control functions may be exercised by a micro-programmed computer.

Title: Improvements relating to fluid pressure braking apparatus
IPC: B60T15/30
Filed: 1932-11-30
Abstract: 411,118. Fluid - pressure brakes. WESTINGHOUSE BRAKE & SAXBY SIGNAL CO., Ltd., 82, York Road, King's Cross, London.-(Assignees of Nelson, C. A. ; Wilmerding, Pennsylvania, U.S.A.) Nov. 30, 1932, No. 33917. Convention date, Dec. 1, 1931. [Class 103 (i).] The initial movement towards application position of a triple valve in an automatic compressed air brake system effects the venting of the brake pipe to a reservoir which is provided with a leak port whereby the venting continues if the valve does not move to application position; in the application position venting of the brake pipe to the reservoir is stopped, but it is then vented to the brake cylinder until the cylinder pressure reaches a predetermined value. In the release position of the valve shown, air from the brake pipe 46 feeds to the auxiliary reservoir 3 through passage 14, piston groove 33 and valve chamber 7, and the brake cylinder 4 is open to atmosphere through passages 26, 34, 35 and retaining valve 2 which normally allows complete exhaust of the cylinder. A valve 22 operated by a diaphragm 21 and controlling communication between the brake cylinder passage 26 and passage 41, 43 is normally unseated by spring 45, the chamber 23 being open to atmosphere at port 24. Upon a light reduction in brake pipe pressure sufficient to move the auxiliary slide valve 11, the brake pipe is vented to a reservoir 17 through passages 15, 38, 37, 36, 20 and if the main valve 10 then moves to application position, the connection to the reservoir is stopped by the lapping of passages 36, 38. If, however, the valve does not move, the brake pipe continues to vent through a restricted port 18 in the reservoir 17. When the valve 10 is in the application position, the brake cylinder is supplied from the auxiliary reservoir 3 through passages 44, 26 until the passage 44 is lapped by the return of the valve 11 and at the same time, the brake pipe vents to the brake cylinder through passages 15, 40, 41, 43, 26 until the cylinder pressure reaches a value sufficient to close the valve 22. When for replenishing the auxiliary reservoir on a down grade the valves 10, 11 are alternately moved to application and release position, with the pressure-retaining valve 2 in operation, the venting of the brake pipe to the reservoir 17 takes place at each application, but since the cylinder pressure is retained there is no further venting of the brake pipe to the cylinder.
