Title: Improvements in process of simultaneous assembling and insulating of the parts of electric outfits
IPC: H01R43/24
Filed: 1921-08-24
Abstract: 168,325. Robinot de la Richardais, D. M. G. Aug. 25, 1920, [Convention date]. Void [Published under Sect. 91 of the Act]. Moulding electric lamp sockets &c.-A process for simultaneously assembling and insulating the metal parts of electric devices consists in assembling the constituent parts so as to conform to the required shape of the article, filling in the apertures necessary for the working of the device with a wax of low melting-point, and surrounding the assembled parts in a mould with insulating paste, the paste being then heated at first gently to melt the wax and coagulate the paste, and finally to a higher temperature to complete the solidification of the paste. The process is described with reference to the connecting devices of electric lamp sockets, described in Specifications 145,774 and 150,726, [both in Class 39 (ii), Electric lamps, Incandescent], which are mounted in pairs in the middle of three superposed discs 6, 7, 8 forming a mould, of which the lower has apertures for insertion of the uninsulated plungers 2, while the upper has parallel bars and slots 10, 11. The bars are formed of the cross-section shown to allow escape of the melted paraffin, The insulating paste is driven into the mould placed in a recess under the piston of a hydraulic press through the slots 11, and the mould is then heated in a water bath to 100‹ C. to melt the paraffin and coagulate the albuminoids of the paste, and finally to 250‹ C. to bake the paste, which preferably consists of a mixture of blood fibrin, dextrine, calcium carbonate, with vegetable waste matter as a binder.

Title: Improvements in electrically controlled counters
IPC: H04B1/08
Filed: 1936-08-14
Abstract: 475,753. Counting-apparatus. ETABLISSEMENTS E. JAEGER. Aug. 14, 1936, No. 22482. Convention date, June 27. [Class 106 (i)] In counting-apparatus in which the counterdriving shaft is driven through a frictional connection by a power shaft and is controlled by an escapement electrically actuated in accordance with the movements to be counted, total and trip counters are provided, the latter being operated by the counter-driving shaft through a manually-settable clutch. The invention is described as applied to counting the rotations of a distant shaft. The shaft carries contacts which cause the alternate energization of electromagnets 20, 21 which rock an escapement lever 15 about its pivot 16, the escapement lever allowing the step-by-step movement of a counter-driving shaft 7 which is constantly urged to rotate by a continuouslydriven power shaft 4, Fig. 4, connected to the shaft 7 through a friction coupling 11. The shaft 7 is connected by gearing to a pinion 28 on the shaft 29 of a total counter 30. A pinion 38 is freely mounted on a shaft 39 and is kept in position on the shaft by springs 45, 48. The pinion 38 engages the pinion 28 and also a similar pinion 37 of a trip counter 36. The shaft 39 can be moved axially to the right to disengage the pinions 28, 38 and thus to break the drive to the trip counter by turning a cam 52 which rocks a lever 49 bearing on the end of the shaft 39. The cam is mounted on a shaft 53 having a setting knob 72. The springs 45, 48 prevent injury occurring to the teeth of the pinions if these teeth are not in meshing positions at the beginning of the movement of the shaft 39. The end of the shaft 7 projects through the case and carries a pointer 65 which shows whether the shaft is rotating. Zeroizing.-The cam 52 can be turned still further clockwise until its point 52c rocks the lever 49 to move the shaft 39 to the right until the pinion 38 engages a gear 55 driven from the continuously rotating shaft 4 through gearing 57. The pinion 38 remains in engagement with the pinion 37 and the gear 55 moves in such a direction that the trip counter 36 is rotated backwards to zero. The cam 52 must be held by means of the knob 72 during this zeroizing action. Specification 275,217, [Class 106 (i)], is referred to.

IPC: H01F29/14
Filed: 1951-09-27
Abstract: 712,124. Transformers and inductors. POSTMASTER GENERAL. Nov. 18, 1952 [Sept. 27, 1951], No. 22620/51. Class 38(2) A transformer or inductor whose loss over a given frequency band or attenuation-frequency characteristic can be varied, comprises a core having one or more limbs 1 carrying the main windings 6, 9, a limb 3 carrying a winding 12 which forms or supplies a subsidiary load, and a saturable limb 2 which shorts limb 3. Direct current is passed through a main or other winding on limb 1, producing a flux in limb' 2 which saturates to a controlled extent, and the main flux is proportionately diverted to limb 3, where it induces voltage in windings 12. Thus the loss in the transformer is varied by changes in the D.C. and each value of D.C. gives a corresponding attenuation - frequency characteristic. The D.C. may be replaced by a permanent magnet. A transformer according to the invention may be used in a telephone system as described in Specification 712,123, [Group XXXIX].

Title: Variable speed pulley and belt driving mechanism
IPC: F16H9/06
Filed: 1955-08-12
Abstract: 782,395. Driving mechanism for typewriters. ROYAL McBEE CORPORATION. Aug. 12, 1955 [Sept. 30, 1954], No. 23341/55. Clas 100(4) [Also in Group XXIV] An electric typewriter is driven from an electric motor B through belt and pulley gearing and a clutch, driving a stepped pulley 51 connected by a flexible positive drive belt 52 to a second stepped pulley 53 fast with a toothed snatch roller C. The flexible belt 52 is moved from step to step on the pulleys 51, 53 to change the ratio, and hence the speed at which the snatch roller C is driven, by pivoted belt shifters 58, 60 actuated from a lever (not shown) positioned by a detent movable in such a way that the prongs 58a, 60a of the belt shifters are moved to take up any space between themselves and the belt 52 before the actual belt shifting motion takes place (see Group XXIV]. Power is transmitted from the snatch roller C to a type bar 1 by mechanism including a pawl carrier 7 pivoted at 8 to a link 9 pivoted at 10 on a base A, and connected through a further link 9a to the type bar. A pawl 11 is pivoted at 12 on the carrier 7 and is biased in a clockwise direction by a spring 13. The end of the pawl 11 is normally engaged by a trigger 15 pivoted at 16 on the carrier 7 and biased by a spring 18. To operate the type bar 1, a key controlled lever 19 is rocked downwards so that a flipper 20 turns the trigger 15 and releases the pawl 11, which is biased by its spring 13 to engage a tooth on the snatch roller C. The whole mechanism on the carrier 7 is then thrown forward, and the type bar 1 thereby turned clockwise about its pivot point 2 into its typing position. When the momentum of the carrier 7 and associated parts throws the nose of the pawl 11 clear of the snatch roller C, the carrier 7 is raised and swung .clockwise about its pivot 8 by spring mechanism (not shown), to restore the parts to their original positions. The flipper 20 is pivoted at 21 and biased by a spring 23 so that the trigger 15 can be returned to its original position even if the lever 19 is inadvertently held in the operated position, instead of being released. The extent to which each individual actuator 7 is driven by the snatch roller, and consequently the force of the typing impact, may be changed by varying the extent to which the nose of the pawl 11 moves downwardly into toothed engagement with the snatch roller. The carrier 7 is formed with a stop finger 26, and the pawl 11 is formed with a finger 27 which can engage the finger 26 when the trigger 15 has been operated to release the pawl. Engagement of the finger 27 with the stop finger 26 limits the depth to which the nose of a pawl 11 can move downwardly towards the snatch roller C. By bending one of the fingers 26, 27, or otherwise varying the proximity of one to the other when the parts are in their normal position, the limiting effect of the stop finger 26 on the rocking of the pawl 11 may be adjusted.
