Title: Improved means for actuating the brake and other mechanisms of talking machines fromthe tone arm or other member moving in conjunction therewith
IPC: G11B17/02
Filed: 1925-12-24
Abstract: 249,452. Gramophone Co., Ltd., (Victor Talking Machine Co.). Dec. 24, 1925. Brakes, disposition of; sound-boxes, raising, lowering, and returning to starting position; multiple machines.-In gramophones wherein the movement of the tone-arm or other member moved by the stylus actuates mechanism for controlling the brake or repeater mechanism, or the means for changing records and raising lowering and positioning the sound-box, &c., the tonearm or other stylus-moved member has a projection engaging between spring-pressed jaws on the controlling mechanism to ensure steady engagement without chattering. As shown, a base plate 3 supports a pivoted member 1 carrying the brake pad 4 and a pivoted pawl 13 which is normally engaged by a trip lever 6 mounted by pivot 7 on the plate 3 and formed with a serrated extension 21. A projection 18 on the stylusmoved member is lightly gripped between pivoted and spring-pressed jaws 22, 23 one of which is mounted by pivot 17 on the base 3 and extended at 16 to carry a spring-controlled pawl 19. As the stylus tracks the record, the pawl 19 rides along the serrated extension 21, and on completion of playing the stylus is caused to make a small reverse movement whereby the projection 18 acts through the pawls 22. 16, 19 to rock the lever 21, 6 clear of the pawl 13 so that the spring 15 turns the member 1 to apply the brake. If it is desired that a further inward movement ininstead of a reverse movement shall release the brake, the jaw 23 is made integral with the part 16.

Abstract: 744,143. Thermocouples. WILD-BARFIELD ELECTRIC FURNACES, Ltd. Dec. 18, 1953 [Dec. 29, 1952], No. 32897/52. Class 53. A thermocouple 1 forming a part of a temperature measuring apparatus is housed in a tube 2 which passes through one or more walls of the furnace and is open to the atmosphere at both ends. One end of the tube is at a lower level than the other so that when the tube is hot air passes through it and removes any gases which may have diffused through the walls of the tube. Fig. 1 shows a construction in which the tube is bent so that it passes through only one wall of the furnace. Fig. 2 shows the tube passing through opposite walls. In other constructions the tube passes through the top wall only of the furnace, and through a side wall and the bottom and through the top and bottom walls. The air flow through the tube may be regulated by a screw 7.

Abstract: 889,805. Knitting-machines. COURTAULDS Ltd. Oct. 22, 1958 [Oct. 23, 1957], No. 33042/57. Class 74 (2). [Also in Group XXXVII] A switch, for controlling the speed of rotation of a warp beam in a knitting-machine in dependence upon the tension of the warp thread, comprises a lever 1 pivoted at 2 and movable in either direction from the mean position shown under the control of the tension. Movement of the lever 1 closes contact pair 3 or 4 and, eventually, contacts 13, 13a or 12, 12a, contacts 12, 13 being mounted on a plate 8 also pivoted at 2 but having its movement damped by friction pads 9 . . . 11. After these latter contacts are closed, the lever 1 engages a stop 6 or 7 and carries plate 8 with it. The contact pairs 3 and 13, 13a and 4 and 12, 12a are connected respectively in series with means for restoring the tension to normal, and when the lever 1 accordingly commences to return to the mean position, the plate 8 remains stationary, and the contacts 12, 12a or 13, 13a open to de-energize the control means before lever 1 returns to the mean position, thus preventing over-correction.

Filed: 1968-07-11
Abstract: 1,205,877. Sheet casting. IMPERIAL CHEMICAL INDUSTRIES Ltd. 25 June, 1969 [11 July, 1968], No. 33110/68. Divided out of 1,014,022. Heading B5A. A casting band for use in the formation of plastics sheet material is made by casting a layer of an organopolysiloxane gum composition on a master pattern, allowing the composition to cure to an elastomeric sheet, removing the cured sheet from the pattern and abrading that surface of the cured sheet which was in contact with the pattern. With such a casting band, slippage of the cast plastics sheet and the band during operations performed on the plastics sheet whilst it is still on the band is prevented without diminishing the ease with which the cast sheet may be finally peeled from the band. The abrading may be applied only to certain discrete areas of the band and may be effected by chemical means or mechanical means such as moving the band under tension over an abrasive surface, for example, a fabric mounted upon a support, treating the band with an abrasive powder, sand blasting the band or applying rotating brushes to it.

[Class 102 (i).] In a means for varying the time of injection of a fuel injection pump relatively to the speed of the engine, a centrifugal governor is driven from the camshaft C of the pump and comprises balls A guided in radial grooves in a cup A1 and engaging a disc D loaded by a spring D2. The disc D is connected by a bell-crank E, E2 to the control valve F of a fluid relay. The control valve F is housed in a bore in the power piston G1 and has ports F3, F4 which in the inoperative position of the fluid relay are covered by the piston G1. These ports F3, F4 are connected by an axial bore to an exhaust port F5. Fluid pressure is admitted by a pipe H and port G3 to an annular space G2 and admission to either end of the cylinder G is controlled by grooves F1, F2. The camshaft C is driven proportionally to the speed of the engine crankshaft by a member L and the piston G1 is connected by a bell-crank J to a collar K, axial movement of which causes relative rotation between the parts L, C. The variation of the timing may be effected instead by adjustment of a valve member in the pump.

[Class 68 (ii).] Breakwaters, jetties, and like works are built with the aid of a bridge one end of which rests on the end of the breakwater and the other end on a support which is floated into position and anchored or secured as necessary. Fig. 1 shows a lattice bridge A supported at one end on a breakwater B, and at the other end on a pontoon C. Filled wagons D are run from an up line on to the bridge, emptied, as at G, and run back to a traverser J, turntables H, and the down line. When the breakwater has been extended, say from L to M, the shore end of the bridge is advanced on the bogie N, which runs beneath or at the level of the top of the breakwater B, the pontoon C being advanced or moved laterally. The pontoon may be replaced by a caisson secured to the sea &c. bed by spikes, or by piles. In a modification, the use of a traverser and turntable is avoided by adapting a turn-out switch connecting the up and down lines. In another modification, separate bridges are used for the up and down lines or each bridge may be used independently.
