Title: Improvements relating to the control of electric motors
IPC: B66B1/42
Filed: 1953-11-27
Abstract: 747,205. Control of two motors. FURSE, H. J. Nov. 1, 1954 [Nov. 27, 1953], No. 32943/53. Class 38(3) Relates to a lift-levelling system comprising a main driving motor F coupled to a low-speed pilot motor G which takes over the drive during starting and stopping operation of the lift-car. Closure of a switch H energizes a contactor C for starting the pilot-motor, and a time-delay relay is also energized so that, after a set period, contacts E are closed for energizing contactor A and connecting the main motor to the supply. The main motor now drives the lift-car and the pilot motor at high speed so that a centrifugal switch L, which is coupled to the shaft of the pilot motor, opens contacts U, N1, to disconnect the pilot motor, and closes contacts U, N. As the car approaches the desired landing, a limit switch I is opened to deenergize contactor A and energize contactor B which introduces reversed braking-current for the main motor. When the speed of the main motor drops to a given value, the centrifugal switch L changesover its contacts to de-energizing the contactor B and energizing the contactor C to re-start the pilot motor. The motor G now drives the lift with the main motor idling until a limit switch J opens to bring the car to rest level with the landing. The Provisional Specification refers to a directcurrent drive utilizing an armature brake for the main motor.

Abstract: 1,177,440. Microcapsules. NATIONAL CASH REGISTER CO. 15 July, 1968 [21 Aug., 1967], No. 33566/68. Heading B8C. Microcapsules are made by dissolving a filmforming polymeric material in a first liquid, bringing this liquid together with a second liquid which is a non-solvent for the polymeric material in such a way that a dispersion of the solid or of one of the liquids in the other liquid is formed and the polymeric material is precipitated at the interface, thereby to encapsulate the dispersed phase. Alternatively, a particulate solid which is soluble in the first liquid or which has been treated with a liquid miscible with the first liquid is dispersed in the polymer solution, whereby precipitation of the polymer on the particles is effected. Thereafter, the microcapsules may be removed from the residual liquid and dried. Suitable liquid pairs are water and acetone, ethanol, dimethylformamide tetrahydrofuran or dimethylacetamide and acetone and heptane or cyclohexane. Specified wallforming polymeric materials are polyethyleneimine, poly-(vinyl methyl ether-co.maleic anhydride), polyvinylpyrrolidone, poly-(styrene-co-maleic anhydride), polyacrylic acid copolymers and polyvinylchloride copolymers. Examples are given in which the polymer is in the dispersed or continuous phase, in both phases and in a continuous phase in which is dispersed silica gel particles containing absorbed acetic acid.
