Filed: 1962-08-02
Abstract: 1,011,153. Impulse transmitters. TELEMAXVENKAUFSGESELLSCHAFT FUR WECHSELSPRECHANLAGEN m.b.H. Aug. 2, 1962 [Feb. 20, 1962], No. 29740/62. Heading H4K. In an impulse transmitter provided with a plurality of cams each of which is contoured so as to be representative of a complete telephone number and each of which is associated with a cam follower, a selection operation comprises moving a selected one of said followers into engagement with its cam and a common locking pawl whereby the cams are caused to rotate, the resultant movement of the follower being transmitted via the pawl to a clutch which controls the operation of a pair of impulsing contacts. Depression of a selection key 14 (Fig. 1) in the direction of arrow 15 causes the associated cam follower 6 to move in the direction of arrow 18 whereby a cam-locking lever 46 is released and a switch 29 is operated in order to connect up the drive to the cams and to operate an electromagnet 30 which locks follower 6 in its operative position. Rotation of the cams causes follower 52 to raise the cam followers 6 which are not involved in the present selection process, while the particular follower 6 which is involved co-operates with projections 4 on the associated cam whereby locking pawl 10 is periodically actuated. Movement of pawl 10 is transmitted via levers 56, 58, 60 to an impulse lever 62 which in turn releases clutch 69 and opens contacts 79. The clutch (Fig. 2) comprises a hollow hub 74 which is spring-urged against a friction disc 72 attached to motordriven shaft 71 and it is released when lever 62 is disengaged from one of the teeth 66 (Fig. 3). An impulse wheel 78 (Fig. 4) is thereby caused to rotate and in so doing it periodically opens and closes contacts 80 which in conjunction with contacts 79 determine the number of impulses and the interdigital pause transmitted to the line. At the end of one revolution of the cams, a lever is moved by a projection on a cam 13 whereby the apparatus is switched-off and follower 6 is released. The cams are held in place by means of the shaped rod shown above driving shaft 1 in Fig. 1 and it is itself retained in either the " locked " position shown or in the " release cams" position by means of an arcuate spring (Fig. 7, not shown). A key is provided for rotating this rod to its " release " position (Fig. 5, not shown) and a keyhole and escutcheon plate are also provided (Fig. 6, not shown) whereby the key may only be inserted and operated when the apparatus is in a specified position. Means may be provided whereby the keys 14 are only operable when the handset of an associated telephone subset has been removed from its rest.

Abstract: 357,385. Force-feed lubricating. BABCOCK & WILCOX, Ltd. and LENNOX, A., Babcock House, Farringdon Street, London. Oct. 6, 1930, No. 29932. [Class 12 (iii).] Apparatus for lubricating the roller axles 3 of a conveyer 2 comprises a lubricant gun 1 mounted centrally in a subsidiary carriage 5 movable at rightangles to the track 4 in a main carriage 8 movable parallel to the track on guide rods 9 on a fixed platform 11. The gun is mounted on the end of an arm 10 pivotally mounted on the platform 11. A trigger 12 pivoted on the carriage 8 is adapted to be entrained by the axles 3 as they pass. The advancing movement of the carriage 8 causes the gun to move forward into engagement with the axle nipple 3b and effects the depression of the gun plunger la, whereby a charge of lubricant is ejected into the axle. The trigger then engages a cam surface 18 whereby it is depressed clear of the axle and the apparatus returns to its original position against rubber buffers 24 under the action of a spring 22. The carriage 8 is fitted with plungers 25, 25a slidable on one of the rods 9 and moving in cylinders 26 so as to form dashpots, the forward cylinder 26 being fitted with a spring to accelerate the return movement of the apparatus. In the form shown in Figs. 1 and 2 the apparatus is arranged to lubricate alternate axles only, a system of levers and links 27 .. 30 being operable by a passing axle to elevate the trigger 12 into a position to engage the next but one axle. The apparatus may be rendered inoperative by displacing the pin 30a into the part 29a of the slot in the link 29. A catch lever 31 is formed with a detent adapted to engage the trigger so as to deaden the recoil on the buffers 24, the trigger being released from the catch as it is raised by the lever 30. In the form shown in Figs. 7 and 9, the apparatus is arranged to lubricate successive axles, a cam 40 being provided to elevate the trigger on the return movement of the carriage 8. This cam may be swung clear of the trigger, so as to render the apparatus inoperative, by means of a lever 41, operable through a bell-crank lever 42. A catch lever 43, acted on by a spring 44, is released through a lever 46 adapted to be raised by the conveyer axle. The levers 43, 46 may be put out of action by means of a wedge 45.

Title: Improvements in or relating to electronic devices
Inventor: WILLIAMS OWEN GRIFFITH
IPC: H04Q11/04
Filed: 1947-11-11
Abstract: 668,521. Automatic exchange systems. STANDARD TELEPHONES & CABLES, Ltd. Nov, 5, 1948 [Nov. 11, 1947], No. 29986/47. Class 40 (iv). [Also in Group XL (c)] The position of an output pulse in a recurring cycle of timing periods is changed in dependence upon the duration of an incoming signal. The Figure shows the application of such a circuit in an automatic telecommunication system in which each pulse in a sequence of timing pulses corresponds to a given line and in which in response to pulses controlled by dialling the timing pulse corresponding to the particular line required may be selected. A sequence of equally spaced timing pulses, each corresponding to a given line are applied at terminal LTP to the anode A of a gas-filled sequence tube. If say ten pulses are applied at LTP a discharge takes place between the anode and the first cathode point and then spreads along the tube with each subsequent pulse until at the tenth pulse cathode C fires. If now the tube is extinguished locally the sequence will be repeated. To ensure that the discharge always takes place initially across the same gap a priming gap P is used which is normally continually discharging. Alternatively one gap may be made of shorter length so that this gap will always strike first as described in Specification 639,827, [Group XL (c)]. If a negative going dialling pulse is applied at X to the normally discharging secondary gap G the gap is prevented from discharging for the duration of the dialling pulse and thus a line corresponding to the duration of the dialling pulse is selected at the output cathode C. A simpler sequence tube may be used comprising a priming gap, a secondary gap and two normal discharge gaps and the tube associated with a delay line to give a step-by-step operation. Thus, if ten timing pulses appear in sequence at LTP and the secondary gap is discharging the first pulse of the sequence causes both ordinary gaps to fire and the remaining nine pulses are absorbed in the delay line. If a negative dialling pulse is now applied to the secondary gap to extinguish'it, two timing pulses are required to strike the two ordinary gaps, nine are absorbed in the delay line, and the output is stepped forward by one pulse. In a further modification a tube having only a priming gap and two normal gaps is used associated with a delay line to retain step by step operation. A positive going dialling pulse applied to the normally discharging priming gap raises the level of ionization so that one timing pulse strikes both ordinary gaps and thus advances the sequence one step.

Abstract: 276,541. Tomlinson, A. V., (Westing- house Air Brake Co.). Nov. 30, 1926. Heat of compression, absorbing.-In a reciprocating compressor the outlet valve casing is connected to the cylinder through a relatively narrow neck of material of relatively low heat conductivity such as cast iron. The cylinder casing 3, Fig. 1, includes bearing surfaces 4, 5 for a sleeve 6 which controls the admission of fluid and forms a bearing for the piston 7. During the suction stroke, the sleeve flange 16 bears on its seating 17 and fluid is admitted through the annular passage 18, during the compression stroke, the sleeve is slid upwards by the piston to rest against a seating 34 in the cylinder head and the compressed fluid is delivered by the discharge passage 15 past the discharge valve 21 to the delivery pipe 27. The neck 30 of this pipe is made as thin as possible and of a material of low heat conductivity, and the passage 18 is of conical shape and is entered by an extension 29 on the piston head to ensure the complete discharge of compressed fluid from the cylinder. In a modification, the cylinder head is cooled by a water hopper and in another form the valve casing is insulated from the cylinder head by material such as mica. The compressor may also be combined with devices for allowing the admission of cooling fluid to the cylinder under the control of a thermostat. The fluid to be compressed flows through a screen 19 in an annular duct 34 past a spring loaded valve 49 to a channel 40 leading to the top of the cylinder 32. A supply of atomized cooling- fluid flows from a supply pipe 56 past a needle valve 57 controlled through linkwork 61 by a thermostat 65 interposed in the discharge pipe 27.
