Title: Magnetic arc blow-out device
Inventor: MAGGI ERNESTO
IPC: H01H9/42
Filed: 1968-09-09
Abstract: 1,235,300. Arc extinguishing in switches. E. MAGGI. 9 Sept., 1968 [9 Sept., 1967], No. 42756/68. Heading H1N. In an arc extinguishing arrangement an arc 141 driven away from separating contacts 121, 130 by permanent magnets 123, 133 is made to run across the surface of a resistor stack 112 thus inserting progressively more resistance in series with the arc. As shown in Fig. 7 a main movable contact 124 is withdrawn in the direction of the arrow (this may be an arcuate path, Fig. 6, not shown). The auxiliary contact 130 initially follows under springs 137 causing a first arc 141 to be struck; this is driven by a first pair of magnets 120 on to the resistor 112 where it is then acted on first by magnets 118, then by magnets 123 moving the other end of the arc on to a second resistor 153. The contact 124 separates from the auxiliary contact 130 to strike a second arc 144 which is driven (in the other direction) along resistor 153 and a runner 115 by pairs of magnets 133, 128. The pairs of magnets 123, 133 have insulated pole pieces 127, 139 which are interleaved so as to provide a labyrinthine path to extend the arc. If the arcs are not cleared in the first half cycle they restrike at the contacts and move in the opposite directions into the unused sections of the chute during the next half cycle. A number of simpler forms of the invention are described: in Figs. 1-3 (not shown) intended for D.C. use only the upper half of the arc-chute is required; the auxiliary contact 130 and the resistor 153 are omitted. In a modification of this (Fig. 4, not shown) the arc runner 115 is replaced by a second resistor (32<SP>1</SP>). In a double chute for A.C. the auxiliary contact 130 and resistors 153 may also be omitted (Fig. 5, not shown) or it is possible to omit the resistors 112 allowing both arcs to run on resistors 153 only (Fig. 9, not shown). The arc-chute may be in open air or immersed in an arc extinguishing gas or liquid in a tank (207) (Fig. 6, not shown). The resistors which may be subdivided by metal plates 113 into sections of different resistivity may be made of high resistivity manganese alloys or of coils of resistance wire or of finely divided carbon or metal in a ceramic base. Non linear resistors may be made of silicon carbide crystals bonded by ceramic.

Title: Grinding machine
IPC: B24B47/20
Filed: 1962-11-13
Abstract: 958,738. Ratchet gear; securing gearwheels on shafts. CINCINNATI MILLING MACHINE CO. Nov. 13, 1962 [March 29, 1962], No. 42825/62. Headings F2Q and F2U. [Also in Division B3] In a grinding machine (see Division B3) a shaft 67 is rotatable in bearings located in a bushing fixed in a portion 48. An overrunning sprag-type clutch engages with a clutch bushing 72 keyed to the shaft 67. The clutch comprises a casing 73 rotatable relative to the portion 48 a limited amount. Inside the casing is a cylindrical sprag pin 74 held in close proximity with the bushing 72 by an adjustable plunger 75. The sprag pin 74 is held in simultaneous contact with the face of the plunger 75 and the bushing 72 by a spring-loaded plunger 76 urging the sprag pin 74 toward a fixed pin 77 attached to a bracket 78 secured to the portion 48. The longitudinal axis of the plunger 75 is slightly offset from the centre of the shaft 67 so that the space between the bushing 72 and plunger 75 is wedge shaped. When the casing 73 is rotated clockwise the sprag pin 74 is wedged and rotates the shaft 67, the amount of clockwise rotation being limited by the clearance between the pin 77 and the end of the cavity in the casing 73. When the casing 73 is rotated counterclockwise, the sprag pin 74 is released and is caused by the spring-loaded plunger 76 to follow back round the bushing 72 until it engages the fixed pin 77 which causes the plunger 76 to shift slightly and allow the pin 74 to stop slightly before the casing 73 is stopped. This moves the sprag pin 74 out of simultaneous contact with the plunger 75 and the bushing 72, so that the bushing 72 and shaft 67 may be freely rotated in either direction. Thus a slight relative rotation between the bushing 72 and casing 73 is required to move the clutch from a released position to an engaging position, the amount of movement being varied by adjusting the plunger 75. A spring 81 in compression between the portion 48 and the casing 73 urges the latter counterclockwise to the released position. A shaft 98 has a flat-sided end 98a loosely received in a sleeve 99 rotatably mounted by bearings in a depending yoke 48a. A gear 102 is integral with the sleeve 99. A roller collar 107 fixed to the end of the sleeve 99 has axles 109, 110, 111. A double ball bearing roller 112 rotatable on journal diameter 109a of axle 109 engages the flat surface of the shaft 98, and single ball bearing rollers 113, 114 rotatable on journal diameters 110a, 111a of the axles 110, 111 engage the cylindrical surface of the shaft 98. The journal diameters 109a, 110a, 111a are round but eccentric to the longitudinal axes of the axles. Rotation of the axles, which are releasably held in the collar by set screws, preloads the rollers 112.

Title: Improvements in or relating to control apparatus using magnetically recorded programmes
Inventor: JACKSON JOHN ALFRED
IPC: G05B19/16
Filed: 1962-11-22
Abstract: 992,520. Cutting machines. E. K. COLE Ltd. Nov. 14, 1963 [Nov.22, 19621, No. 44109/62. Heading B4B. [Also in Divisions G3 and G5] A control apparatus for use with a magnetic track with a programme of signals recorded thereon, is provided with means whereby the output of a pick-up head operable by the track is clipped to reduce noise in the output, the level at which clipping is effected being varied in dependence on the relative speed between the track and the head, so that as the speed increases the clipping level is increased, thus opposing an increase of noise in the output. The apparatus may be used to control a paper cutting machine in which the paper and a magnetic tape or wire are advanced step by step in synchronism. A mark on the tape is received first by a " slow " head L1 and causes a high-speed clutch E to be disengaged and a low-speed clutch D to be engaged to cause slowing down of the paper and tape. After an interval the mark is received by the " stop " head L2 which causes the paper to be stopped so that a cutting operation may be carried out. The outputs from the heads pass to clipper transistors TR1 and TR2 which are biased by resistances R3 and by capacitors C1 with variable resistors R4. When the tape is moving at high speed, capacitors C1 are charged to a voltage proportional to the - 24 volts in the clutch circuit; the transistors are thus biased to a relatively high voltage, and R4 is adjusted so that clipping is carried out at a level just above the noise level. When the tape is moving slowly switch S1 is closed and capacitors C1 discharge leaving the biases to be determined by R3 at a lower level sufficient to clip at the noise level at the lower speed. In order that the clipping level may be maintained just above the noise level as the speed of the tape decreases, the rate at which the bias decreases is suitably selected. The variable bias may. alternatively be derived from a tachogenerator.

Abstract: 958,238. Control of A.C. motors. SQUARE D CO. Dec. 30, 1960 [Dec. 30, 1959], No. 44875/60. Heading H2J. Relates to an induction motor 10 which is controlled by means of saturable reactors, having main windings HX1, HX2, LX1, LX2 and BX, in the manner described in Specification 956,287. When a load is hoisted into a limit switch 70, contacts LS1, LS2 are closed and contacts LS3, LS4 are opened. This connects stator terminal T2 directly to line L2, impedance 71 being shunted across terminals T1, T3. Terminal T1 is effectively disconnected from line Ll due to the impedance of winding LX1, the terminal T3 being disconnected from line L3. At this time, and even though master controller 30 provides a hoist control signal, the motor is de-energized and the brake 60 is set. If the master controller is operated to provide lowering operation, the impedance of winding LX1 is reduced so that lines L1, L2 are now connected to terminals T1, T2 and the brake is released. The motor will rotate in the downward direction and the limit switch will normally be re-set. However, if the limit switch fails to re-set, the load becomes overhauling and rectifier units 34, 35 respond to the combination of the reference signal from controller 30 and feed-back signal from tachometer generator 31 to control the downward movement. When the feed-back signal overcomes the reference signal, the motor is de-energized and the brake is applied to stop the load, whereupon, the reference signal again overcomes the feed-back signal and the cycle is repeated until the load reaches a safe resting position. In another arrangement, the reversing reactors are replaced by contactors, Fig. 2 (not shown).

Abstract: 1360400 Digital transmission: multi-station operation HONEYWELL INFORMATION SYSTEMS Inc 30 Sept 1971 [30 Sept 1970] 45654/71 Heading H4 A general purpose digital computer connectible to a number of remote terminals, e.g. teleprinters operable at different speeds and formats is programmed to detect and identify incoming address characters or a portion thereof and to establish communication between terminal and computer. The computer may be time shared among the terminals through a common data set which determines the pulse repetition rate and provides synchronization. Terminals 1-5 are connected to data sets 6-10 and a telephone switching network to a remote computer which embraces a data set 12 and line adapter 15 which comprises a control unit 16, character sync. unit 17 and the code unit 18. Communication between a terminal, e.g. 3 is established by an operator to data set 12 which changes line 19 to "1" which places a "1" on line 20 indicating that a call is being received, also on line 21; when communication has been established line 22 also changes to "1", The reply signal to a terminal energizes an indicator. The teleprinter carriage is then returned and an answer back key operated causing a series of identifying characters to be transmitted which are temporarily buffered in unit 17 for examination by unit 18 which switches unit 17 to the appropriate pattern relative to the data format. The identifying character is also sampled at a rate equal to the highest transmission rate and the bit patterns thus generated are analysed. Due to different speeds, identifying characters will take different lengths of time to transmit hence are divided into first, second character portions &c. the part relative to high speed being received in the first portion, but as this relative to the other speeds may contain two indeterminate bits, sampling procedure is carried out in the second portion. A number is developed for the first character portion and a second number which may be the same or different for the second character portion which numbers uniquely identify the particular character speed. Arrangements for performing these functions are described in the specification. If an operator should press an incorrect key this would be identified in a third character portion which resets the system. A timer may be incorporated to limit the number of improper identification characters also the length of time that a character may be transmitted. D is connection of a terminal performed by the operator. The programme may be in the form of punched cards or magnetic tape. In the embodiments described the identification character is preferably "carriage return" as this function must be performed by an operator; the speed relations from the various terminals should preferably be so arranged to avoid an ambiguous change of state during signal sampling periods which may eliminate a second test during the second portion.
