Title: Electric Motor Control System
IPC: H02P7/00
Filed: 1967-03-22
Abstract: 1,168,563. Control of A.C. motors. BORG-WARNER CORP. 22 March, 1967 [8 April, 1966], No. 13538/67. Heading H2J. [Also in Division H3] The speeds of a plurality of motors are controlled by regulating the frequency of respective inverters from which they are supplied by signals derived from a single variable frequency oscillator 13 and divided in a "countdown" circuit which produces one output pulse for a predetermined (and adjustable) number of input pulses. The system is applied to a plurality of motors driving textile machinery; there are a number of channels, each having its own master inverter and countdown circuit, triggered by the common master oscillator, and there may be more than one motor, such as 44, 48, in each channel, each motor supplied from its own slave (power) inverter. The voltage to each motor is varied by a motor operated variable transformer controlled to keep "volts per cycle" constant. The frequency of the master oscillator is varied by a motor driven potentiometer and relay circuits are described (Figs. 2a, 2b, not shown) whereby, at the press of a "start" button the frequency is increased from zero, but the motors are not energized until a predetermined frequency is reached at each master inverter and individual "run" buttons are pressed. At this point the potentiometer motor is stopped and all motors are energized at this minimum frequency. Operation of a master "run" button then advances the oscillator frequency to maximum, when the potentiometer motor is stopped by limit switches. Various interlock contacts are provided, and there is a "jog" button to operate motors 44, 48 before the minimum frequency is reached. In an alternative arrangement the frequency is never reduced to zero, the potentiometer motor being stopped when the minimum frequency is reached during run down, ready for immediate re-start. The frequency detecting circuits are described (Figs. 3 and 4, not shown, see Division H3). The inverters preferably comprise thyristor circuits.

Title: Electro hydraulic transducer
IPC: F15B21/042
Filed: 1971-05-06
Abstract: 1347317 Fluid regulation I J CYPHELLY 6 May 1971 [6 May 1970 30 March 1971] 13541/71 Heading G3H An electro-hydraulic transducer comprises a tube 1 having a terminal lug 4 at its low pressure end and a flange 3 soldered to its high pressure end, the lug being insulated from contacting parts. An electric current input 5 connected to the lug serves to heat the tube through which tube the hydraulic medium flows, the rate of flow of medium being governed by the supplied electric current. Such rate of flow is dependant upon the changes induced in the inherent properties of the medium by the heat supplied to it from the tube. Figs. 3-14, (not shown), depict modified forms of the tube. The transducer may be incorporated in an hydraulic bridge circuit Fig. 15, (not shown), having a trimming restrictor Fig. 16, (not shown). The restrictor takes the form of a pipe (27) arranged helically around a threaded bolt (31) extending from a base (30), the pipe resting on the base (30) and being acted upon by a washer (33) underlying a nut (32) movable along the bolt (31). Electric overloading of the tube is prevented by arranging the tube such that it bends on heating Figs. 17-19, (not shown), and eventually trips either a mechanical switch actuator or interrupts the supply of light to a photo-electric cell arranged in the supply of power to the tube.

Abstract: 439,738. Cutting plastic material. ROSE, A. G., and ROSE BROS. (GAINSBOROUGH), Ltd., Albion Works, Gainsborough, Lincolnshire. May 5, 1934, No. 13605. [Class 87 (ii)] Mechanism for feeding and cutting a bar of toffee &c. stock comprises means for feeding the bar continuously to the cutting position, a knife rotating about an axis parallel to the bar, cam mechanism to reciprocate the knife longitudinally of its axis so as to move in the same direction and at the same speed as the stock during cutting and to return between the cutting operations, and a plunger which moves the cut pieces laterally while they are still moving with the stock. The bar 10 of toffee &c., is fed through a guide channel 11 by friction rollers 14 driven by gearing. The knife-blade 17 is fixed to a boss 18 on a shaft 20 which is driven through gearing 21, 29, the wheel 29 being wide enough to allow longitudinal movement of the shaft 20. The shaft carries a cam groove 23 which engages a roller 24, mounted on a rigid arm 26, to reciprocate the said shaft during the cutting operation. The end 36 of the channel 11 is formed obliquely so as to co-operate with the knife in a shearing action. The severed pieces are pushed by a plunger 33 into the jaws 34 of a mould wheel carrying with them wrapping material 35. The knife may be replaced by an eccentrically mounted cutting disc.

Abstract: 1507485 Digital data processing NATIONAL SEMICONDUCTOR CORP 7 April 1975 [6 June 1974] 14184/75 Heading G4A A digital data processing system uses the operation code portions of macroinstructions read from an external store 10, Fig. 1, to access microinstructions in a control store 22, which may be a read-only memory, the system being adapted to accommodate macroinstructions having variable length operation codes. The operation codes are first transferred to an instruction register 18 and thence to address generation means 20 where they are converted to addresses for the control store, the address generation means 20 including a logic array decoder 30, Fig. 3. Operation code bits fed to inputs 32 of the decoder pass to respective lines 36 and, via respective inverters 34, to further respective lines 38: selected ones of the lines 36, 38 form the inputs to AND gates 40 which have outputs on lines 42, selected ones of the lines 42 forming the inputs of OR gates 44 whose outputs provide the addresses to the control store. The interconnections within the decoder 30 are selected by masking during manufacture, the bit positions of decoder 30 each being programmable as "1", "0" or "don't care", the don't care bits being ignored in the decoding process. In order to reduce the capacity of the decoder 30, the arrangement is such that different inputs to the decoder 30 may produce the same output. In a modification, Fig. 5 (not shown), the instruction register 18 is connected directly to the address portion of the control store 22 instead of via the address generation means 20, the control store 22 incorporatings its own logic array decoder 30; this is stated to reduce execution time. In Fig. 6 (not shown) each of the address generation means 20 and the control store 22 incorporates its own logic array decoder 30, a set of AND gates (52) connected between the instruction register 18 and the control store 22 setting all bit positions in an address register (46) of the control store to zero except for those which represent the operation code.
