Title: Improvements in and relating to infinitely variable speed gearing
IPC: F16H3/44
Filed: 1927-10-27
Abstract: 283,094. Wallis, W. Oct. 27, 1927. Variable-speed gearing comprises a long gear A<1> having teeth which taper in the axial direction, so that variations in speed are effected by the axial displacement of this gear. In the arrangement shown, planetary gears M are carried by a drum P which has a one-way clutch connection I with a sleeve C fast on the driven shaft A. The gear A<1> drives and an internal gear L is carried by a loose drum H. In the configuration shown in Fig. 1, the gear train is jammed to drive solid by the thickest parts of which the teeth of the gear A' an end view is shown in Fig. 4. As the gear A<1> is moved to the right by a control slider S, there is slipping of the gear teeth over one another with much friction, with a result that the shaft A is driven at a speed which decreases progressively. On further movement of the gear A<1>. a brake M' is applied to the drum H by suitable means, so that when a point F1* is in the phase of the gear train, the internal friction has ceased, and the planets roll on the fixed gear L driving through clutch I at a definite low speed. When point E1<SP>*> comes into the gear plane, the brake M<1> is released, producing a neutral. Continued movement applies a brake G<1> to the drum P, so that drum H is driven reversely, and through a clutch D which is brought into action, reversed driving is effected.

Title: Improvements in devices relating to winding bobbins, spools and the like of wire, threads and the like
IPC: B65H57/20
Filed: 1932-10-13
Abstract: 401,483. Controlling delivery in wire and like winding-machines. JONES, G. V. WYNNE-, O'SHAUGHNESSY, H. E. P., LISLE, W. G. DE, and SOPER, H. N., (trading as SHAWNDEL TOOL CO.) ; 99, Regent Street, London. Oct. 13, 1932, No. 28572. [Class 120 (ii).] In delivery-controlling devices of the kind comprising a rotary flyer or guide arm and a stationary bobbin for use in winding bobbins, spools, cops, hanks, and balls of yarn, thread, cord, rope, wire and the like, particularly for winding fine wire for electrical purposes, and wherein the flyer is controlled by a brake adapted to be applied when the draw-off tension is relaxed, the flyer is resiliently connected to a brake in such manner that the pull of the flyer places the connection under load prior to the application of the brake and the connection and brake exercise control during winding to impart a working tension. The flyer 3 is carried by a head-piece 13 secured to a spindle 12 mounted in ball bearings in a casing 10, which serves as a brake drum and is mounted in a support 9 provided with a peg 8 fitting tightly into the bobbin support. A light coil spring 16 is secured to the spindle 12 and bears directly or through shoes 17 on the surface 10<a> of the brake drum, so that when starting-up the spring 16 yields and frictional slip occurs after the flyer has gained momentum, and when stopping the flyer will stop at once or, if it continues to rotate, the brake will grip as the speed is reduced and the spring 16 in unwinding will reverse the rotation of the flyer and rewind any slack. The spring is hooked to a shoulder on the base piece 12<a> of the spindle 12 so that it is automatically disengaged upon reverse rotation of the whole device. An auxiliary spring 18 is provided to impose normal pressure on the shoes. The Provisional Specification describes also the application of an air brake to the head-piece when winding fine wire and a friction brake for heavier work.

Patent GB-635059-A (GB)
Title: Improvements in control systems for dynamo electric machines of the flywheel equaliser kind
IPC: B60L50/30
Filed: 1946-09-26
Abstract: 635,059. Automatic current control systems. PESTARINI, G. M. Sept. 26, 1946, No. 28746. [Classes 35 and 38 (iv)] The current in the primary circuit of a metadyne transformer 1 driving a fly-wheel and consequently the line current in supply lines L1, L2, is maintained constant under varying load conditions on a motor 2 by control of the acceleration or deceleration of the metadyne 1. As shown, the speed of the metadyne 1 is controlled by a regulator dynamo 8 and a saturated exciter 13 so as to produce in the primary winding 10 a voltage equal to the difference between the voltages of the armatures 8 and 13. The machines 1, 8, 13 are mechanically coupled together. The speed of the metadyne is maintained at the critical speed of the dynamo 8, since if the speed of the metadyne rises the dynamo 8 operates to retard the metadyne, and if the speed falls the exciter 13 tends to accelerate the metadyne. The critical speed of the dynamo 8 is determined by a rheostat 15 in series with the winding 9 of the dynamo 8 and controlled by a reversible motor 16 having opposed field windings 21, 22. The winding 21 is under constant energization from conductors 6, 7 whilst 22 is energized in accordance with the primary current a, c of the metadyne. The arrangement is such that during acceleration of the metadyne 1 to store energy in the fly-wheel upon a change of load on the motor 2 to a light load, the acceleration is controlled so as to maintain the primary current a, c constant. This action is brought about by the windings 21, 22 which cause adjustment of the rheostat 15 in one direction or the other to effect critical speed control of the dynamo 8 and metadyne 1. By means of a switch 20 which may be operated automatically, the connections of the windings 21, 22 may be reversed so that the system may operate in a similar manner when the metadyne 1 is driven as a generator by the fly-wheel to supply the motor 2 when the latter is subjected to heavy loads. A manual controller 5 comprising rheostats 19, 23, 4 is provided for setting the initial running conditions, whilst limit switches are provided on the rheostat 15 for ensuring that the metadyne speed will not fall below a predetermined minimum or rise above a predetermined maximum. The Provisional Specification refers to an alternative arrangement wherein the auxiliary motor 16 operates at constant speed when the primary current has the correct value, this speed being varied, however, to effect compensation when the current departs from its correct value. Specifications 635,062, [Group XXXVII], and 635,063 are referred to.

Abstract: 1400792 Photographic process giving imagewise distribution of a reagent POLAROID CORP 20 June 1972 [21 June 1971] 28797/72 Heading G2C A photo-sensitive element comprising an exposed silver halide emulsion is developed with an aqueous alkaline processing composition to form in the undeveloped areas an imagewise distribution of soluble silver complex which is contacted with a compound capable of being cleaved in the presence of the complex to liberate a reagent and thereby form an imagewise distribution of the reagent, the reagent being a gelatine hardener, a development restrainer, a toning agent, an antifoggant, an aldehyde, a ketone or a silver halide solvent. The photo-sensitive element may have a sheet, which may comprise an image-receiving layer, attached to its support and overlying or capable of overlying the silver halide emulsion. The material may comprise a processing composition or the components thereof capable of being spread as a layer between the silver halide emulsion and the sheet. The processing composition may be an aqueous alkaline solution of silver halide solvent and developing agent. The compound may be in a layer between the support of the photo-sensitive element and the sheet when it overlies the emulsion or in the processing composition. One of the compound and liberated reagent may be diffusible and the other non-diffusible. Cleavage of the compound may result in the formation of one of the reagents and also a different compound that is a colour providing moiety or it may result in the formation of a colour providing moiety that is also one of the reagents. The process may involve diffusion of a soluble silver complex imagewise and liberation of a diffusible colour providing moiety e.g. a dye and a development restrainer or anti-foggant, the colour providing moiety diffusing to a receiving layer (see Fig. 1 not shown and Example 3). Alternatively, the imagewise distribution of soluble silver complex may diffuse to a material comprising a colour providing material and liberate (i) a diffusible colour providing moiety e.g. a dye thereby leaving in the material a dye image (see Fig. 2 not shown) or (ii) an aldehyde which is also a colour providing moiety which couples with a methylene coupler e.g. malononitrile to give a dye image (see Example 4). The compound may contain the group and may be a thiazolidine or benzothiazoline. The formulae of 36 dyes having cleavable thiazolidine or benzothiazoline nuclei are disclosed.
