Abstract: 646,813. Sashes balanced by springs. GENERAL BRONZE CORPORATION. Nov. 18, 1947, No. 30565. Convention date, May 20. [Class 20(iii)] In windows of the type wherein a vertically sliding sash is balanced by tension springs secured to the lower corners of the sash and to the frame header, the sash carries friction shoes adapted to engage with and slide on an adjacent surface of the frame to exert a frictional force thereon which equalizes the balancing effect of the springs, said shoes also co-operating with devices adapted yieldably to lock the sash at predetermined positions. The figures show the invention applied to a window having double-hung, vertically sliding metal sashes. A plate 35 is secured to the web 21 at each lower corner of each sash and has a resilient flange 37 to which is attached the balancer spring 34. A shoe 38, of self-lubricating material, is mounted on flange 37, which presses the shoe resiliently against the adjacent flange of the window frame thus providing a force which, in all positions of the sash, equalizes the effect of the springs 34 or the weight of the sash, so that the sash will remain in any desired position. To provide a more positive but yieldable locking of the sashes in their open or closed positions, the shoe 38 has a pair of cam faces 39 and 40 which co-operate with cams 41 placed at appropriate positions on the frame. The Specification as open to inspection under Sect. 91 also describes and illustrates an equalizer which does not incorporate the cam device but which can be adjusted for pressure by screw means.

Abstract: 651,118. Control of several motors. TESCHER WYSS, Ltd. Dec. 1, 1948, No. 31136. Convention date, Dec. 8, 1947. [Class 38(iii)] [Also in Group XXXVIII] A control member, e.g. a servo-motor control valve p for adjusting the pitch of a marine propeller may be actuated from any one of a plurality of identical service stations such as I, II, III each of which includes two identical shunt wound motors M, M' and shunt resistances N, N', the motors driving respectively through gearing s and clutches k the sun wheels of a differential D the planet member a of which drives through gearing e, t and a friction clutch r wiper arms of the associated resistances N, N<SP>1</SP>. Assuming, e.g. that the control member H at any station, e.g. station I is moved in one or other direction, a push button switch c associated therewith and actuated simultaneously energizes a relay m which sets the associated time switch Z into operation and energizes over a contact v of the time switch the station relay R which energizes a contactor X to connect the D.C. power lines E over auxiliary lines E<SP>1</SP> to the motors M, M' at stations II and III only. The resistance N at each service station controls the excitation of motor M at the same station but the resistance N<SP>1</SP> controls the excitation of the motor M<SP>1</SP> at the next station in the cycle I, II, III, I. Thus in the example quoted, the movement of the control member H at station I varies the resistance N<SP>1</SP> to vary the excitation of motor M<SP>1</SP> in station II where the motors M, M<SP>1</SP> now run at different speeds and through the differential D adjust the control arm H and resistance N until they correspond in position to that of the control member H at station I when the two motors run at the same speed. The adjustment at station II also sets the associated resistance N' to vary the excitation of motor M<SP>1</SP> in station III where the control arm H and resistors N, N<SP>1</SP> are, similarly set into correspondence with those of stations I, II. The valve p is shown as set by the shaft of control arm H at station III but it may be set from any of the stations.
