Title: Improvements relating to the stroboscopic observation of shafts and like rotating members
IPC: G01P3/66
Filed: 1945-10-08
Abstract: 600,980. Electric indicating systems. BRITISH THOMSON-HOUSTON CO., Ltd., and CASTELLAIN, A. P. Oct. 8, 1945, No. 26170. [Class 40 (i)] The speed or other characteristic of a rotating body is measured by inducing a voltage in a coil at each revolution of the body and applying this transient voltage to a cathode ray oscillograph arranged to indicate the speed or other characteristic. Two or more pick-up coils may be used, e.g. for indicating the torque transmitted by a shaft one of the pick ups being used to trigger the line scan of the C.R.O. As shown, the shaft 4, Fig. 4, whose speed is required, carries a disc 3 having a magnetic inset 2 which co-operates with fixed magnetic elements 1a, 1b (the inset 2 or the elements 1a, 1b being permanently magnetised) to induce transient voltages in pick-up coils 10a, 10b mounted on the elements. These voltages are fed to a C.R.O. 13, the voltage from pick-up 10a triggering the line scan and the voltage from 10b producing a blip in the line at a position corresponding to the shaft speed. Alternatively, the speed may be indicated by the adjustment of the line scan sweep speed control necessary to bring the blip to a standard position. The pick-up coil 10a may be dispensed with in which case the line scan control is derived from a separate source. In the Fig. 5 arrangement, a third pick-up coil 10c is provided co-operating with a magnetic inset 2a in a collar 15 secured to a sleeve 16 fixed to the shaft 4 at a remote point 17. As before the output from coil 10a is used to trigger off the line scan and the outputs from coils 10b, 10c used to produce blips on this line the displacement between which is a measure of the torque transmitted by the shaft. Alternatively the torque may be indicated by the adjustment of the line scan sweep speed control necessary to main the blips at a standard spacing corresponding to, e.g. zero torque. In a modification, Fig. 6 (not shown) the disc 3 has two circumferentially spaced magnetic insets for providing improved indications on the C.R.O. According to the Provisional Specification the apparatus may be used for determining the angular displacement between two shafts and hence the slip in a magnetic coupling or belt drive.

Title: Small micro-programme data processing system employing multi- syllable micro instructions
IPC: G06F9/22
Filed: 1973-06-05
Abstract: 1426748 Micro-programmed data processor BURROUGHS CORP 5 June 1973 26716/73 Heading G4A High level language program instructions are executed by microinstructions including multisyllable microinstructions the syllables of which are read from memory in sequence. Program instructions and data and microinstruction syllables are stored in different parts of a read/ write memory or in separate memories, e.g. a read only microprogram memory may be used. Microinstructions are implemented by control words in a control memory 37. The operator field of a program instruction is processed to obtain a start address. Each microinstruction has an operator syllable and may have one or more further syllables representing literal values to be used as address parameters, the syllables being read in sequence from the microprogram memory to a buffer 24 which, when holding an operator syllable, acts as an address register for control memory 37. Each control word read from memory 37 specifies the combination of registers to be employed and the function to be performed. Transfers take place through an arithmetic and logic unit 20 via input buses A, B and output bus F having the same width as a microinstruction syllable, e.g. an 8-bit byte. The control words also select one of two memory address registers 25, 26 in increment or decrement mode, specify the number of clock times required for microinstruction execution, provide for conditional exit from microinstructon execution and include a literal value. A microinstruction fetch operation is overlapped with microinstruction execution using a first in last out push down stack 36 for microprogram memory addresses. The overlap between microinstruction address incrementing and microinstruction execution is dependent on the current machine state and the type of the current and next (in buffer 24) microinstruction. The number of clock times required for microinstruction execution is determined by a counter in control block 39 which is loaded from a control word, the block 39 indicating eight machine states (including two delay states) which determine when microinstruction syllables are fetched. An auxiliary counter 40 can specify up to 256 data transfers for one microinstruction e.g. for use in searching for a particular value in a string of data segments.  Provisions for conditional jumps, subroutine jumps and interrupt are described.

Abstract: 1364371 False twisting process and apparatus friction twisting HEBERLEIN & CO AG 8 June 1972 [8 June 1971] 26831/72 Headings DID and D1F In a process for false twisting a yarn, the yarn 1 is moved in contact with at least one moving friction member 2, and tensioned such that a force component is exerted normal to the friction surface in contact with the yarn, the yarn tension being controlled whereby reductions in the degree of twist imparted to the yarn result in an increase in yarn tension thereby increasing the frictional force between the friction surface and the yarn and a compensating increase in the degree of twist imparted to the yarn. The friction member is preferably a roller which may be barrel-shaped or be in the form of a disc with a rounded edge. In an alternative embodiment several discs are arranged one above the other with the edges partially overlapping. Alternatively the friction surface could be on the inner circumference of a tube provided with flared entrance and exit apertures.  In the preferred embodiment of friction member the external surface of a disc 2 is provided with raised friction tracks 4 which in use are at an angle to the direction of yarn movement. In the event of slippage occurring between the yarn and the surface, the tracks cause a frictional force component to act on the yarn in the direction opposite to that of yarn movement which thereby increases the yarn tension P 2  and thus the force normal to the friction surface. In a further embodiment, a raised strip contiguous with the tracks extends around the member 2 at the maximum diameter thereof. The yarn is heated during the false twisting process.
