Title: Linear actuator
IPC: F15B11/12
Filed: 1962-03-22
Abstract: 949,894. Fluid pressure apparatus. EXCELL-O CORPORATION. March 22, 1962 [March 23, 1961], No. 11003/62. Heading F1P. A linear actuator comprises a plurality of substantially concentric cylindrical elements 30, 32, 34, 36, 38 slidably disposed within each other, each of the elements being closed at both ends by end caps having aligned bores 90 slidably receiving a shaft 10, a piston element 11 on the shaft slidable within the innermost of the cylindrical elements, means biasing the cylindrical elements and the shaft in one direction, means 98, 100, 102, 104, 106, 108 limiting the travel of each cylindrical element within the element surrounding-it and the piston element within the innermost cylindrical element, and conduit means selectively introducing pressure fluid into the annular chamber defined by one end cap of any of the elements and the end cap of the element contained therein, whereby the immediately contained element is caused to travel a predetermined distance within the containing element and the shaft to travel the same distance, the total travel of the shaft being the sum of the travels of all the elements actuated. The actuator may be used in a control system to convert a binary number into an analogue equivalent in a data processing, digital computor machine tool or other automation system. The means for limiting travel of the elements consist of shoulders 98, 100, 102, 104, 106, 108 on the end caps, the travel permitted to each element being twice that of the element in which it is contained. The outer element 12 is provided with a plurality of conduits 122,124,126,128,130,132 which are connected to chambers 134, 136, 138, 140, 142, 143, respectively, by grooves and passages in the elements, and fluid pressure supplied to the conduits biases the elements to the right. The conduits are paired respectively to conduits 194, 196, 198, 200, 202, 203 leading to chambers 204, 206, 208, 210, 212, 214 at the opposite ends of the elements and are controlled such that if one conduit, say 122, of one pair is connected to exhaust, the other conduit 194 of the pair is connected to the source of pressure. Selective connection of the conduits 194, 196, 198, 200, 202, 203 to the source of fluid pressure, which may be oil, water, compressed air, gas or steam moves the associated element to the other end of the limit of its travel, the shaft 10 moving a distance equal to the sum of the individual movements. A linkage may convert the linear movement of the shaft to a rotary movement. Springs may be provided to bias the elements to their right-hand positions. U.S.A. Specification 2,911,956 is referred to.

Abstract: 996,896. Knitting-machines. SDRUZENI PODNIKU TEXTILNIHO STROJIRENSTVI. March 21, 1963 [March 24, 1962], No.11187/63. Heading D1L. A four feed circular knitting machine comprises a yarn holding device which includes a suction tube 13 located between the cut off position and the main feed position is a cover element 8. The cover element comprises a plate 8 of relatively large area which extends circumferentially from the cut off position around to the feed rotation furthest removed therefrom. The suction tube 13 is located in the cover element 8 at a position in the immediate vicinity of the cut off position V and is operated during the working periods of the machine. An electrically heated wire 32 serves to sever the main yarn and a second heated wire at VI serves to sever the reinforcing yarn and is movable radially of the needle cylinder. The suction tube clamps the yarn and removes waste ends after severing. When a main yarn 24 is taken out of operation it passes into a space to between the plate 8 and the dial cap 2 and in the space 10 it is guided by pins 11 to the suction tube 13. The introduction of the yarn to the space 10 is facilitated by the provision of toothed segments 12 on the plate 8. The dial cap, cam ring and dial may be replaced by a cone 38 arranged in coaxially the needle cylinder, Fig. 8 (not shown).

Title: Improvements relating to intelligence communication systems
IPC: G08C21/00
Filed: 1959-04-02
Abstract: 858,327. Writing telegraph. MERO, P. G. S. April 2, 1959 [May 19, 1958], No. 11227/59. Class 40 (1). In a writing telegraph system the signal to control the engagement of the receiver stylus with the recording medium is derived from the condition of an oscillator whose frequency determining circuit is inductively coupled to a resonant circuit in the stylus the resonant frequency of which changes when the stylus is moved into contact with the recording medium. Three arrangements of stylus are described. Transmission of copying signal.-As shown in Fig. 2, inductors 25, 28 are adjusted in accordance with the co-ordinate components of movement of the stylus to vary the frequencies of corresponding generators, signals from which control motors to move the receiver stylus. Stylus engagement control.-Fig. 3 shows a stylus engagement control system in which an oscillator 58 has a resonant circuit comprised of coil 56, wound round the writing platen, tuned by condenser 57. The writing stylus comprises a writing element, such as a ball point pen cartridge 61 slidably mounted in stylus barrel 60 and spring biased to an extended position as shown. Writing contact between the stylus and platen, however, moves cartridge 61 into the barrel and closes contacts 63 and 64 which completes a resonant circuit comprising condenser 72 and coil 70. The completion of this circuit, which is tuned to the same frequency as oscillator 58, changes the oscillating conditions of circuit 58, e.g. emitter current of a transistor oscillator, which change can be detected and signalled to the receiver to control the receiver stylus engagement. Stylus operation modifces tuning of the circuit in alternative forms of the device, movement of the writing element tunes the circuit to resonate at the appropriate frequency by moving a high permeability core into the centre of the coil, Fig. 5 (not shown), a further alternative, more suitable for use with a pressure sensitive recording medium, is shown in Fig. 7. In this embodiment coil 115 is wound on a core 113 of material having a permeability which varies substantially with flux density, which material is also used for the marking tip 112. Adjacent to the core is a permanent magnet 114 and when the marking tip is brought into contact with a platen of high permeability material the flux density in the core 113 increases substantially. In this manner the coil 115 may be tuned to bring the resonant circuit, coil 115 and condenser 116 to the oscillator frequency to operate the pen lift control circuits in the manner described above. Specifications 677,177, 678,469, 686,599 and 702,058 are referred to.

Abstract: 183,558. Barraquer y Barraquer, I. April 22, 1921. Eye instruments a n d appliances; pneumatic appliances.-For removing a cataract in its capsule, a rapidlyoperated intermittent or vibratory suction device is applied to it so as to effect a rupture of the fibres of the zonule at positions near the lens without the tension causing the rupture being communicated to the peripheral connections of the fibres. The apparatus described comprises a suction nozzle shown in Fig. 2, with an application cup 1, and an electricallyoperated device having a rapidly-operated piston 31, Fig. 4, which acts as a pump to exhaust air through a conduit 35 connected to the teat 20 of the suction nozzle. The suction device has interconnected valve elements 15, 11, which allow the operator to open or close the passages 7, 8 communicating with the atmosphere or pump device respectively. The amount of the suction in the nozzle may also be adjusted by providing the closure member 18 of the nozzle with a port 22 adapted to be moved into or out of register with a passage 17 communicating with the atmosphere. The rotor 24 of the motor has a flexible spindle 28 connected to a cylindrical rotary member 29 seated in a recess 34 of the casing. Within a cylindrical recess in the member 29 is housed the piston 31, which has a cross slot 32 engaged by an eccentrically-placed pin 33 secured to the bottom of the chamber 34. The ends of the recess in the member 29 are brought into register with the port 35 and with a recess 39 and conduit 37 leading into a well 38 containing oil. As the motor is rapidly rotated, the piston 31 is reciprocated to extract air from the conduit 35 and expel it through the conduit 37.
