Title: Electrical connector and prong receiving terminals therefor
IPC: H01R4/20
Filed: 1963-07-11
Abstract: 1,006,055. Two-part couplings. UNITED-CARR Inc. July 11, 1963 [Dec. 31, 1962], No. 27608/63. Heading H2E. An electrical connector terminal 20, 42 (Fig. 9) comprises a tubular body formed with a prong-receiving bore 26, 52 and a portion 30, 48 to which may be attached a lead wire, the wall of the bore 26 being formed, at longitudinally spaced intervals, with projections 34-38, 54-58, which cause the lateral deflection of an inserted prong. Two such terminals 20, 42, together with a resilient prong 40, form a connector, the male member comprising the terminal 42 with the prong 40 held tightly by the internal projections 54-58, and the female member comprising terminal 20. The prong may be inserted into the bore 26 of the terminal 20, which is of slightly greater diameter than that of the terminal 42, to ensure that on disengagement of the members, the prong is retained by the terminal 42. The prong is located within the terminal 42 by the constriction 50. The terminals may be mounted within apertures 60, 64 in separate insulating bodies 62, 66, and are of minute dimensions (examples are given) and suitable for multiple connectors. The terminals are formed with flared mouths for easy insertion of the prong 40 and the projections are obtained by deforming the tubular body. The prongs may be mounted direct in an insulating body.

IPC: H04Q3/42
Filed: 1954-09-24
Abstract: 815,979. Automatic exchange systems. SIEMENS EDISON SWAN Ltd. Dec. 9, 1955 [Sept. 24, 1954], No. 27712/54. Class 40 (4). The value of a digit is represented by the ratio between two time intervals of which one is a reference interval and is nominally constant, the two intervals being those between three pulses sent at each operation of a dial or other transmitter, so that selection is independent of the speed of operation. The receiving equipment employs as distributers, counters and registers a number of multi-cathode gas-filled cold-cathode tubes in which pulses applied to a pair of guide electrodes such as ge1, ge2 cause the discharge to step along the cathodes, the discharge being normally on cathode O. The dial pulses are applied through gate valves VI, V11 to distributers D1, D11. In positions 1, 4, 7, 10 D1 opens a gate V2 to allow 1150 c/s. pulses to step counter D3 for the measurement of the reference interval of successive digits. D3 acts as a frequency-divider, and each time it passes positions 1 and 6 a pulse is transmitted through V5 to step counter D6. In positions 2, 5, 8, 11 D1 allows 1150 c/s. pulses to step a similar frequency divider D2 for the measurement of the digit interval and this controls a counter D5 similar to D6. Each time D5 passes position 9, however, a pulse is sent through valve V3 to a decade counter D4. The reference interval corresponds to the digit 1 and D3 should take 115 steps and D6 23 steps. To allow for variations of dialling speed it is assumed that the discharge in D6 is on one of cathodes 1 to 5 at the end of the reference interval. The comparison be. tween the digit interval and the reference interval is made by means of five trigger pairs G1 ... G5, and in positions 2, 5, 8, 11 distributer D11 allows input to registers D7 . . .  D10 in succession by opening gates such as V12. Counter D6 in accordance with its setting primes the left-hand tube of one of the trigger pairs, e.g. V8 if D6 is in position 2, and decade counter D4 on reaching position 2 transmits a pulse to all the left-hand tubes causing the primed tube V8 to fire. The rise in cathode potential of V8 primes the right-hand tube V 10, and this fires when the discharge in D5 reaches the cathode connected thereto, transmitting a pulse to the register connected up by D 11. The rise in potential on cathodes 1 ... 9 of counter D5 (which are connected to resistance R11) shifts the discharge to cathode O, and a pulse delivered over cathode 9 steps decade counter D4 to position 3. The fired tubes V8, V10 become extinguished. Counter D5 continues to count in conjunction with decade counter D4, and each time the setting corresponds with the reference interval a further pulse is sent to the register, and counting starts afresh. Finally the digit interval is terminated, and D1 in resting position 3 transmits a pulse through tube V6 to zeroize the counters, after which all the operations are repeated for subsequent digits of the dialled number.

Title: Improvements in or relating to electric circuit-breakers
IPC: H01H33/04
Filed: 1931-10-06
Abstract: 390,226. High-tension switches. REYROLLE & CO., Ltd., A., Hebburn-on- Tyne, and ALLAN, A., Cragside, Ashleigh Grove, Tynemouth. Oct. 6, 1931, No. 27715. [Class 38 (v).] In switches with contacts in. explosion pots one of the contacts is mounted on a piston within the pot so that any arc produced in closing develops a pressure which acts on the underside of the piston to close the switch more firmly. As shown in the Figure, a piston D is arranged within a cylinder A<2> formed integral with the pot A<1> at the upper end of which is a renewable contact stud B<2> screwed into the central conductor stem B. In the closed position shown, the contact B<2> is engaged by the upper of two renewable contact studs E, F mounted in conducting connection with one another in the hollow stem of the piston. To close the switch, the hollow main contact G is raised so as to press apart and pass between the sections J of a clip contact which are mounted on the piston and held by a garter spring J<1>. With further upward movement the contact F is engaged and the piston raised so as to bring the stud E into contact with the fixed contact stud B<2>. If an arc is drawn in closing, the gas pressure developed passes through the channels A<3> to the large underside of the piston and raises it so as to close the switch firmly. In breaking the circuit, an arc is first drawn between the contacts B<2>, E as the intermediate contact-member E, F follows the main contact G downwards under the action of the spring H. This arc, however, develops a pressure which brings the contacts B, E together again, thus accelerating the separation of the contactmember G from the contacts F, J and transferring the arc thereto. This arc produces a blowout stream of oil across the gap and through the hollow contact-member G into the switch tank. The lower orifice of the pot is closed by an insulating ring K having some free lateral movement.

Card feeding hopper 15.-A flanged plate 24 is locatable in the hopper by pins which engage apertures in plate 40 so that 96-column cards can be accommodated between walls 24, 40, 52 and flange 44 in a face-up attitude. The hopper may be modified to take 96-column cards in a facedown attitude by inserting a different flanged plate having a wall which is off-set from wall 40 to allow for the asymmetrical nature of the cards. Card feeding and transport mechanism.- The botom card of a stack is engaged by the front or both of a pair of high friction rollers 62 which are mounted in unidirectional bearings and are driven by a motor through a pulley and belt drive and a 1/3 revolution clutch, Fig. 4 (not shown). Transport to and from the sensing station is effected by drive rollers 112, 110 and idler rollers 118, 116 which are mounted on a yoke 122 supported by spring blades 124, 126 and raisable for access by an over-centre mechanism 130. A nudge roller 132 is driven by a belt from the idler roller shaft to ensure that cards completely enter the stacking hopper 50. Card stacking hopper 16.-Modification to take the 96-column cards is effected by inserting a similar plate 24 to that used in the feeding hopper, the plate being inverted, as shown. A pair of card-receiving platforms 192, 194 are each biased upwards by a spring 206 and a wire looped over pulleys 210, 216. When 96-column cards are being received in hopper 16, platform 192 is lowered under the weight of the cards independently of platform 194. When 80- column cards are received on both platforms 192, 194, projection 222 on platform 194 engages projection 220 on platform 192 through a resilient pad 224 to ensure that both platforms move in unison.

Abstract: 691,490. Loading detonators. IMPERIAL CHEMICAL INDUSTRIES, Ltd. Sept. 24, 1951 [Nov. 15, 1950], No. 27906/50. Class 9(i) A machine for placing empty detonator tubes into a carrying plate as described in Specifications 622,527 and 683,482 is provided with means for conveying a succession of empty carrying plates beneath the delivery tubes, side guides being provided to locate each plate as it approaches the tubes. Preferably each plate is slightly inclined to its direction of motion so that the rear edge of a filled plate leaving the feed tubes is slightly above the level of the leading edge of the next oncoming plate. Fig. 1 shows a chain conveyer 1 with chairs 2 parallel to the direction of motion to support carrying plates 3. The plates pass between guides 6 and are spaced by distance-pieces 8 as they are conveyed beneath delivery tubes 5 to receive the empty detonator tubes 7. The leading edge of each distance-piece is at a lower level than the rear edge, and also at a lower level than the top surfaces of the carrying plates, while the rear edge is above the level of the. top surface of the carrying plates. Thus after a plate is filled the detonator tubes next in the line of feed are supported by the distance-piece 8 until the next succeeding plate comes into position. In an alternative arrangement the carrying plates have extensions to the rear and leading edges taking the place of the distance-pieces. These extensions are so arranged that the maximum space between adjacent plates is not greater than the transverse section of the detonator tubes. The chairs have inclined carrying surfaces so that the rearward extension of any plate is at a higher level than the leading extension of the next succeeding plate, i.e. the rearward extension is nearer to the outlets of the delivery tubes.

Title: Salts of disubstituted carbamic acid esters and a method for the production thereof
Filed: 1956-09-14
Abstract: The invention comprises compounds of the formula: <FORM:0801533/IV (b)/1> (wherein R1 is phenyl or benzyl which may contain nuclear alkyl, alkoxy, halogen or nitro substituents, R2 is alkyl or any one of the values of R1, R3 is alkyl or alkenyl containing from 8 to 18 carbon atoms and X- is a pharmaceutically acceptable anion) and their preparation by reacting the appropriate disubstituted carbamic acid ester of 3-pyridinol with a quaternizing agent R3X and, if desired, converting in a known manner the salt so obtained into a salt having a different anion.  The quaternization, which is advantageously performed at between 80 DEG  and 160 DEG  C., may be effected with an ester of an hydrohalic acid, and the replacement of the anion by a different anion may, for example, be effected by conversion into the quaternary base with subsequent neutralization with an acid containing the required anion or by passage of an aqueous solution of the salt through an anion exchange resin.  Examples describe the preparation of the N : N-diphenyl-carbamic acid esters of 1-(n-decyl)-, 1-(n-octyl)-, 1-(n-undecyl)-, 1-(n-dodecyl)-, 1-(n-hexadecyl)-, 1 - (n - octadecyl) - and 1 - [undecen - (11) - yl]-3-hydroxy-pyridinium bromides, the conversion of the first of these compounds to, separately, the corresponding chloride and fluoride by anion exchange methods, and the preparation of the N-methyl-N-(p-chlorophenyl)carbamic acid ester of 1-(n-decyl)-3-hydroxy-pyridinium bromide, of the N : N-di-(p-chlorophenyl)-carbamic acid esters of 1-(n-decyl)-and 1-(n-dodecyl)-3 - hydroxy - pyridinium bromides, of the Nmethyl - N - (p - methoxy - phenyl) - carbamic acid ester of 1 - (n - decyl) - 3 - hydroxy-pyridinium bromide and of the N-ethyl-N-(p-tolyl)-carbamic acid ester of 1-(n-undecyl)-3-hydroxy-pyridinium bromide.  Starting materials.  Compounds of the formula: <FORM:0801533/IV (b)/2> may be prepared by esterification of 3-hydroxy-pyridine with the appropriate carbamic acid halide or by the action of phosgene on 3-hydroxy-pyridine and condensation of the so-formed chloro-formic acid ester with the appropriate secondary amine.

Filed: 1945-10-25
Abstract: 599,661. Grinding and sawing machines. FIELDING, E. C. Oct. 25, 1945, No. 28131. [Glasses 60 and 145 (ii)] In a machine having a rotary grinding or cutting-tool, e.g. a saw, the tool 4 is mounted at one end of a shaft 1, the other end of which is driven by an electric motor 9 supported by a tubular housing 10 which encloses the shaft 1, the housing itself being supported by a transverse shaft 38 which is revoluble by a motor 43 so that the tool 4 may be adjusted in a vertical plane to any desired position. The tool-mounting is also vertically adjustable, by a screw 42 driven by a motor 64, on a pedestal 41 which may be revoluble and lockable in its support 65 to permit the tool to be adjusted in a horizontal plane. The tool 4 is clamped between discs 22, 24, the former being splined on the shaft 1 and secured thereon b nuts 23. The housing 10 is provided with an external bearing, between flanges 32, 33, which is rotatable in a two-part sleeve 34, so that he housing 10 may be turned to an angular position in which the guard 13, which is as described in Specification 599,662, [Group XXIV], exposes the tool 4 in proper relationship to the work. It is locked in this position by the catch 35. The transverse shaft 38, which is coupled with the motor 43 through reduction gearing 44, is journalled in a bracket 39 on a sleeve 40 which is slidable vertically on the pedestal 41. The shaft 38 ends in a forked bracket 46, the arms of which carry adjustable screws 47 which locate compression springs 48, one on each side of a web 49 which extends from the sleeve 34 and ends in a slide 50 movable in dovetail guides 51 on the bracket 46. A shock-absorbing mounting for the tool 4 is thus provided, electric contacts 53, 54 being closed, in the event of an overload on the tool 4, to operate a trip switch in the motor circuit. The sleeve 40 is fitted with a rectangular block 55 which slides in a vertical slot 56 in the wall of the pedestal 41, a screw 57 passing through the block 55 having a reduced end 58 engaging in a recess in a nut 59 on the vertical screw-shaft 42 which is rotated through reduction gearing 63 by the motor 64. Limit switches may be provided to restrict the operation of the motors effecting adjustments of the tool 4, and suitable contacts may be provided to bring the tool to any desired position. A flexible dust-removing pipe may be provided with a mouthpiece adjacent to the tool 4. The guard 13 could be omitted for internal grinding, in which case the provision for adjustment of the housing 10 in the sleeve 34 could be dispensed with. The screw-adjustment 57, 59 could be replaced by a chain-and-sprocket gearing.
