Title: Improvements in or relating to dynamic braking of electrically driven machines
IPC: H02P5/46
Filed: 1946-08-15
Abstract: 615,946. Control of A.C. and D.C. motors. HARVEY, V. P., POWELL, G. F. W., and MOLINS MACHINE CO., Ltd. Aug. 15, 1946, No. 24324/46 and 10387/47. [Class 38 (iii)] Travelling to predetermined limits.-In a control system for an electric motor 20 driving a machine 21, 25, means TS are provided which move in timed relationship with the driven parts 23 of the machine which means are adapted to initiate dynamic braking of the motor when a predetermined position is reached by the parts 23 only after the motor has ceased to drive the machine. An A.C. motor may have arrangements for starting under reduced torque. Inching means may be provided. Closure of the switch MS, Fig. 1 (Prov.), energizes relay A/2 over the lines BL1, BL2 which are connected to correspond to the phase of the lines L1, L2. Movement of the control rod 10, to operate the switches LS, RS .simultaneously, from position 1 to position 2 energizes contactor D/4 to excite the twin stator windings W1, W2 and the transformer T to supply rectified current at the star points of these windings and the motor starts with reduced torque. Movement of the switches LS, RS, to position 3 energizes relay C/1 to remove the rectified current from the windings W1, W2 and the motor operates with full torque. To stop the machine the rod 10 is returned to its original position which removes the alternating current from the windings W1, W2 but the condenser K2 holds the relay C/1 operated and the machine runs by momentum. When the predetermined position has been reached the means TS connects a condenser K1, charged through a back contact of contactor D/4, to a relay B/2, whereby rectified current is applied to the windings W1, W2 to effect dynamic braking. Inching may be accomplished by oscillating the switches LS, RS between positions 1 and 2. Fig. 1 (Comp.) shows the system adapted to control a direct current motor A, the controls in this case being the push-buttons PB1, PB2. Fig. 2 (Comp.) shows that, by arranging that the pitch of the pieces on the conveyer is equal to the pitch circle diameter of the conveyer driving wheel and that means TS1 makes three revolutions and means TS2 one revolution, while the conveyer is moving one cycle, the system may be employed with machines having either an acyclic or a cyclic function. Specification 599,100 is referred to.

Title: Improvements in machines for winding yarn
IPC: B65H54/32
Filed: 1921-09-14
Abstract: 187,422. Boyd, T, A., Boyd, H. A., and Boyd, Ltd. J. & T. Sept. 14, 1921. Winding-machines; thread-guides; stop-apparatus, non-automatic.-In a cheese-winding machine, a traverse lever with an unvarying reciprocation is pivoted on the framing and combined with a thread guide, so that as the diameter of the cheese increases the delivery point of the guide is moved nearer to the pivot of the lever, thereby reducing the length of traverse of the yarn, and forming bevelled ends on the cheese. The lever 12 is engaged bv a stud 14 on the traverse bar 13, and the thread guide 15 is pivoted at the lower end of the lever and rests on the cheese. A doublejawed cheese-holder 6 is formed with bearings 6<2> to carry a spindle 7 and a wooden tube 8 which is pressed against the face of a drum 4. As the cheese grows, the curl 15<1> of the guide is raised, and thereby brought nearer to the pivot stud 11. In a modification, applied to a vertical spindle machine, a lever 37, Figs. 4 & 5, is mounted on a traverse shaft 36 in front of each spindle 33, and a thread guide 38 is pivoted to the inner end of the lever. A guide-wire 40 is mounted between the thread guide and a wooden tube 35 on the spindle, and during winding is pressed against the yarn by a spring 38<4> acting on the thread guide. As the cheese grows, the distance of the yarn-delivery point from the shaft 36 is gradually reduced. The thread guide, has a slotted end with bevelled edges 38<2> so that the thread as it rests on the guide-wire will pass into the slot when winding commences. A pivoted brake-lever 43 carries at its upper end a band-tightening pulley 45 which is held in position by a slide-rod 46. When the rod is withdrawn, a spring 44 at the lower end of the lever presses a brake-leather 43<5> against the spindle wharve 33<1>.

Title: Improvements in or relating to the preparation of thermoplastic sheets
IPC: C08L61/10
Filed: 1928-08-28
Abstract: 314,937. Wade, H., (Bakelite Corporation). Aug. 28, 1928. [A Specification was laid open to inspection under Sect. 91 of the Acts, July 6, 1929]. Fabrics composed of fibrous material agglutinated by adhesives.-Thermoplastic sheet material is made by preparing a pulp composed of fibre and a reactive plastic resin in subdivided state suspended .in water or other liquid, continuously forming a sheet therefrom by laying the pulp, draining off excess liquid, and then drying out the residual liquid under conditions which preclude the reaction of the resin to an infusible state and lessening of the plasticity of the resin. Drying may be effected by subjecting the moist sheet to a current of dehydrated air or other gas, the latter being first passed over chemical agents such as concentrated sulphuric acid or calcium chloride. or over cooled pipes in a refrigerating apparatus, and then heated by passage through steam coils. The gas is preferably blown against both surfaces of the paper in the middle thereof. The temperature of the current is regulated according to the progress, of the drying and the nature of the resin, and the actual temperature of the sheet is kept below the fusion point of the resin. An alternative method of drying the sheet, after removing the excess liquid by suction, by shaking, by felt rollers or other means, consists in passing it through a chamber in which it is subjected to reduced pressure and heated by means of heated rollers. Both methods of drying may be used in succession. The process is applicable to sheets containing synthetic resins of all types, but is particularly intended for use with resins of the phenol aldehyde and cresol aldehyde types.
