Abstract: 1,229,834. Switchgear structures. DELLE ALSTHOM. 20 May, 1968 [18 May, 1967; 11 Sept., 1967], No. 24003/68. Heading H1N. A switchgear cubicle contains a multipole circuit breaker 7 with isolating devices 3, 4, each pole of the switchgear including at least one insulating bushing extending between a pair of isolating contacts, the bushings carrying auxiliary devices such as current transformers, 12 and the circuit breaking and isolating contacts and the bushings of each pole being disposed in straight lines and aligned one behind the other in the cubicle. The terminals 53, 60 of the circuit breakers form the fixed contacts of load and line isolators 3, 4 operable conjointly. When the isolators are off, the circuit breaker assembly can be withdrawn on rollers 63. Each circuit breaker comprises a two-part earthed metal gas filled cylindrical case 43, 44 and a pair of insulator bushings 46, 47 respectively housing a tripping mechanism 51 and a puffer 55 for extinguishing the arc. The bushings also carry current transformers 12, voltage transformers 61 and fuses 62. In modifications (Figs. 6, 7, not shown) one or both sets of isolators may be omitted, the terminals of the circuit breakers being staggered vertically or angularly to allow removal of the breakers. When both isolators are omitted isolation is by withdrawal or rotation (Figs. 10, 11 respectively, not shown) of the circuit breaker unit. In Figs. 1-3 (not shown) the cables are located at the bottom of the cubicle and the bus-bars 1 at the top; cable earthing switches (13) are fitted; the cables and fixed contacts of the cable isolators may be in a unit from which the remainder of the cubicle can be detached (Fig. 3, not shown). To prevent access to live terminals the front wall of the cubicle may be formed to fit closely about the circuit breakers when partially withdrawn (Figs. 8, 9, not shown), the opening being closed by a front plate (86) of the withdrawable unit when fully inserted and by a blind or rigid shutters when fully withdrawn, the shutters being coupled to close automatically. Current transformers may be mounted inside the pivoted bushings of the isolators (Figs. 12-15, not shown) and metal screens between the bus-bar, circuit breaker and cable chambers may conform to the outline of the pivoted bushings so that the latter serve as shutters. In alternative circuit breaker units (Figs. 18, 19, not shown) the insulator 46 contains respectively a disconnecting switch, allowing the poles to be used individually while others are earthed, and a cartridge fuse of the kind having a tripping pin for automatically opening the circuit breaker contacts.

IPC: H04L27/227
Filed: 1959-07-15
Abstract: 931,402. Automatic phase control systems; phase shift radio signalling. ROBERTSHAWFULTON CONTROLS CO. July 15, 1959 [Aug. 14, 1958], No. 24372/59. Drawings to Specification. Class 40 (5). Two phases only, differing by 120 degrees, and each producing a zero or positive output respectively from the receiver phase detector are used in FSK signalling. A negative output indicates faulty synchronization of the receiver reference oscillation obtained as in Specification 920,772 by squaring the received phaseshifted carrier, differentiating it to obtain pulses which shock excite a resonant circuit tuned to the third harmonic of the carrier and energizing a counter-type frequency divider with output of one-third the received carrier frequency and of constant phase. The negative output of the phase detector indicating an incorrect discrete phase of the frequency divider output is used for triggering a Schmidt or other pulse generator to step round one transition of a ring counter employing three thyratrons, the pulses being applied simultaneously to each of the control grids. The cathode potentials are applied to open one of three pairs of diode switches connected normally to short-circuit three outputs differing in phase by 120 degrees from three reactive or resistance networks shunting the output of the frequency divider and applying thus one selected reference phase to the receiver phase detector, the ring counter operating once or twice until no negative output is obtained from the phase detector and synchronizing is correct.

Filed: 1971-04-19
Abstract: 1278398 Grinding LITTON INDUSTRIES Inc 19 April 1971 [25 March 1970] 24460/71 Heading B3D  A machine tool for operating on a workpiece, such as a machine for grinding crank-pins 21, 30, comprises a pair of crank-heads 19, a pair of spindles 24 rotatably mounted by respective one of the crank-heads, and a pair of fixtures 26 secured to respective one of the spindles, each fixture having an assembly including a clamping arm 12 which is pivotally mounted to its fixture for holding a workpiece 16, and a latching arrangement 10 which, in a first position, blocks the clamping arms against movement to a workpiece-removal position and releases the fixtures for rotation with respect to the crankheads, and which, in a second position, releases the clamping arms for pivoting motion with respect to the fixtures to a workpiece removal position and blocks the fixtures against rotation with respect to the crank-heads. The crankheads are of similar construction and mounted on a carriage 71 for longitudinal movement to position the crank-pins for grinding by a wheel 22. Each outer bearing pin 16 of the crank-shaft is held in a block 27 on a fixture 26 by movement of the arm 12 about a pivot 94 by fluid pressure supplied to a cylinder 13 moving a piston 89 connected to the arm against a spring 93. An adjustable stop 28 is mounted in the arm and, with a latching element 11 in a forward position permits only slight releasing movement of the arm 12 so that the pin 16 is unclamped and the crank-shaft can be indexed but will not permit the crank-shaft to be unloaded. The latching element is formed on a piston 33 which is movable by fluid pressure in a cylinder 32 against one or more springs 37, 38 to an unlatched position to allow the arm 12 to move to an unloading position. However, such movement is only possible when the fixtures are in the correct angular position which is determined by a reduced end 44 of a plunger 42 connected by a pin 51 to the piston 33 for movement therewith engaging a bore 61 in the crank-head 19. A member 63 is movable by the end 44 of the plunger when it enters the bore to operate a switch 5LS which produces a signal indicating that the fixture is held against rotation. The arm 12 is then moved by spring 93 to its inoperable position by blocking fluid pressure supplied to cylinder 13 to permit automatic loading and unloading of the workpiece. When the new workpiece is loaded, the machine is automatically operated, grinding being effected under the control of a size gauge at a rapid, slow and fine feed rate.

Title: Position compensating arrangement for numerical control systems
IPC: G05D3/12
Filed: 1968-05-23
Abstract: 1,209,330. Programmed control of machine tools. KEARNEY & TRECKER CORP. May 23, 1968 [May 24, 1967], No. 24588/ 68. Heading G3N. A machine tool having an incremental position control system, incorporating a position transducer comprising an elongated scale changing in length with machine tool operating temperature and a positioned sensing head, is provided with a signal modifier adding or subtracting pulses to the positioning system at predetermined increments throughout the range of relative movement of head and scale. As shown, a work-table of a machine tool carries a sensing head 34 co-operating with a scale 30 mounted on the frame and comprising a plurality of magnetic cylindrical pins 38 retained by a clamp 37. The scale is subject to thermal expansion which causes a cumulative error in positioning the work-table; this error is compensated by injection of signals into the numerical control system of the machine tool. The control system is conventional and comprises a data input system 76 providing velocity commands and position commands to a control 98 and register 95 respectively. The existing position of the work-table is set in a position register 55 in dependence on feed rate, from velocity control 98, through a count control 105 responsive to the output of a comparator 114 determining the direction of movement necessary to cause the existing work-table position to attain the commanded position. The count control actuates normal and double count steering gates 122, 130 to modify the count in a command phase counter 74 and generate appropriate quadrature signals in a phase generator 78. The quadrature signals are fed to a bridge circuit 43 which is connected to the windings 41, 42 of the sensing head 43. A phase dependent signal from the circuit 43 is fed through a pre-amplifier and filter 89 and a squarewave shaper 71 to a discriminator 67 providing an error signal 68 to a servo drive 26 for a lead-screw 24 maintaining the work-table at the position held in register 55. Thermal compensation is provided by feeding the count direction commands, on lines 137, 148, from the control 105, and existing position values, on lines 134, 145, to respective right or left travel compensation decoders 135, 147. The right decoder 135, at fixed position intervals, through a compensation control 57, enables the double count steering gates 130 whereby an additional pulse is fed to the phase counter 74. In a similar manner the left decoder 147, at the fixed position intervals, through the compensation control 57, inhibits the normal steering gates 122 whereby a pulse is prevented from reaching the counter 74.

Abstract: 367,765. Refrigerating. RICE, E., 5301, York Road, Philadelphia, U.S.A. Aug. 18, 1930, No. 24667. [Class 29.] Heat is transmitted from a space to be cooled to a solid refrigerant, e.g. carbon dioxide ice or frozen brine, through a heat-conducting surface between which and the refrigerant is placed a sheet of heat-insulating material to control the flow of heat. Fig. 1 shows the upper part of a refrigerator cabinet cooled by carbon dioxide ice supported upon a metal plate 26 having fins 28, a heat-insulating plate 31 being interposed between the plate 26 and the refrigerant which is enclosed by heatinsulation 32. In a modification, the ice is replaced by prismatic containers filled with frozen brine. In a combined cold-storage chamber and water cooler, the ice is stored in a chamber enclosed in an open-topped metal box 55, Fig. 6, which constitutes the conductor, and the water is cooled in a tank 57. The ice and the storage chamber 60 are separated from the conductor by heat-insulating plates. Fig. 7 shows an ice cream cabinet cooled by ice separated by a heat-insulator 65 from a conducting plate 63 having cream containers 62 formed integrally therewith. A refrigerated box comprises a metal storage chamber 101, Fig. 16, separated by a heat-insulator 108 from the ice which rests upon a shelf 106 supported upon legs over which the box sinks as the ice evaporates. A portable refrigerator having covers in its top comprises storage spaces 140, Fig. 23, separated by pervious screens 162 and insulated partitions 148 from the ice container 144, the spaces between the partitions forming air circulation ducts accommodating the fins of the conductor plate 146. The circulation of air through the ducts is controlled by thermostatically-operated valves 150. The ice container is compartmented and heat insulators are placed between the ice and the plate 146 in all or some of the compartments according to the temperature required in the spaces 140. Figs. 27, 28 show a modified form of refrigerator in which the spaces between the ice container and the partitions communicate with the storage spaces through ducts 164a. This latter arrangement is also applicable to railway cars. In another form of refrigerator, an ice-making chamber 166, Fig. 35, is arranged between the conductor plate 146 and the heatinsulator 144a. Fig. 36 shows an apparatus for freezing meat, fish, &c. between plates 204, 208 separated by heat-insulators 207, 211 from the ice. A refrigerator unit suitable for use in chambers to be cooled comprises a metal ice container 269, Fig. 39, the walls of which are provided with fins 256 to which are secured plates 257 to form air flues between the fins.
