Title: Improvements relating to friction clutches
IPC: F16D43/18
Filed: 1959-04-17
Abstract: 910,707. Friction clutches. STROJIRNY POTRAVINARSKEHO PRUMYSLU, NARODNI PODNIK, HRADEC KRALOVE, SAVOD PRAHA-NOVE MESTO. April 17, 1959 [May 7, 1958], No. 13073/59. Class 80 (2). A centrifugal friction clutch for an electric motor, which engages at a predetermined interval after the driving member has attained its maximum speed, comprises a sleeve 13 which is initially driven by friction drag from a driving member 11 on which it is mounted, until a predetermined speed is attained, whereupon spring-retracted centrifugal segments 15 carried by the sleeve 13 move radially into frictional engagement with a V- groove in the driving member 11 whereafter the increased speed of the sleeve 13 causes centrifugal masses 21 to move outward and press spring bands 19 carrying friction linings 20 into engagement with a driven drum 12. The ends of the bands 19 bear against lugs 18 on the sleeve 13 and the masses 21 act on the bands 19 through pads 23, the circumferential position of which may be adjusted to vary the position and magnitude of the components of centrifugal force acting through the pads. The time interval before engagement may be adjusted by adjusting a spring-pressed drag brake 25 acting on the sleeve 13.

Abstract: 323,701. International Harvester Co. of Great Britain, Ltd., (International Harvester Co.). April 27, 1929. Rakes, horse and traction.-In a rake of the kind in which the rocking of the teeth is effected by the operation of pawls or the like engaging with ratchets associated with the road wheels, an overshot toggle is provided for locking the tooth-carrying frame, and the unlocking of the toggle is effected by the lever which is used to operate the pawls. Toggle members 22, 23 are connected respectively to the draw frame and the tooth carrying frame, and an arm 29, to which the operating pedal 13 is rigidly connected, is arranged to bear on the toggle member 23. On depressing the pedal 13, the toggle is first unlocked by the arm 29 bearing on the member 23; further movement of the pedal causes the pawl 10 to engage with the ratchet 2 on the shaft of the road wheels, through links 11, 12, 14, 15, thereby causing the tooth-carrying frame to be raised for discharge. A double-ended pedal 36, 37 is mounted on the toggle member 22, depression of the pedal 36 unlocking the toggle to enable the teeth to be raised sufficiently for backing &c., while depression of the pedal 37 effects locking of the toggle after use of the pedal 36. Further security of the toggle locking device is ensured by a spring-pressed rod 31 between the toggle-member 22 and the draw-frame member 20.

Title: Improvements in or relating to control devices for adjustable electric components
IPC: H03J5/10
Filed: 1946-05-01
Abstract: 617,098. Adjusting radio apparatus. PHILIPS LAMPS, Ltd. May 1, 1946, No. 13168. Convention date, Jan. 14, 1942. [Class 40 (v)] In a system for setting a circuit element, such as a slidable electrode condenser to a number of predetermined positions, of the type in which a follower coupled to the element co-operates with a number of pre-set screws spaced round the circumference of an adjustable disc, the working end of the follower is given a truncated conical profile while the corresponding part of each screw has a curved profile and the maximum differences in height of successive screws is limited to that of the conical portion of the-follower. Figs. 1 and 2 show an arrangement in which follower 14 of condenser 15 is spring urged into engagement with screws 7, having graduated heights and limited in their travel in threaded and smooth bore holes respectively in discs 23 and 9 by bushes 11, the discs being mounted on adjustable shaft 4, springs 21 are provided to urge the screws into engagement with their threaded holes and thus eliminate axial play. A detent system, in which spring urged roller 18 cooperates with notches 17, is provided. In a modification (Figs. 4 and 5, not shown), the relative movement of screws is limited by an arrangement of interacting flanges mounted on the screws. A roller mounted on a pivoted arm may be interposed between the screws and the follower to prevent the transmission of tangential forces from the former to the latter (as in Figs. 7 and 8, not shown), the screw heads being flattened in this case. If a large number of pre-set positions is required successive screws may be arranged alternately on two circles, the follower having a radially aligned wedge-shape profile (as in Figs. 9, 10 and 11, not shown). In the arrangement of Figs. 1 and 2 rotation through more than 360 degrees has to be prevented owing to the large difference in height between the " first and last " screws. This restriction may be removed (as in Figs. 12-14, not shown), by arranging for a lever to lift follower 14 at the appropriate setting of the discs by means of a further lever co-operating with a suitably profiled cam mounted on the disc 22. The system may be used with a remote control system.

Title: Improvements in and relating to the distant control of bascule barriers or gates
IPC: H02P7/00
Filed: 1937-05-10
Abstract: 500,649. Hydraulic transmission of power. BUINI, A. May 10, 1937, No. 13294. Convention date, May 9, 1936. [Class 69 (ii)] [Also in Group XXV] A level-crossing barrier 13 is positively lowered and raised by a piston and cylinder 9 supplied with hydraulic pressure from a reversible electricallydriven pump 8 which is stopped by .limit switches at the end of each operation, the barrier being retained in the open,position by a lock valve 18 so arranged in the pipe 15 which is under pressure during the opening operation as to prevent escape of liquid from the cylinder 9 until pressure is supplied to the other end of the cylinder to close the barrier, a pipe 31 then supplying liquid under pressure to the actuating piston 33 of the valve 18. An electromagnetic valve 39, normally closed and energized, is arranged so that when the electric supply fails the ends of the cylinder 9 are connected to allow the barrier to close by its own weight. The valve 18 is. actuated by its piston 33 through a lost-motion connection (not shown), so that liquid is not released from the upper end of the cylinder 9 to allow the barrier to descend until some time after the pump has been started, and an electrical warning device, switched on at the same time as the pump motor, sounds during this delay period. Signal lamps are provided indicating the setting of the motor control switch and the completion of the motor circuit. The Specification as open to inspection under Sect. 91 comprises also various modifications of the operating mechanism, usually employing an additional lock valve similar to 18 to hold the barrier closed. In one of these arrangements the piston and cylinder are replaced by a rotary vane device geared to a wheel which actuates a mechanical bell and lifts a counterweight attached to a lever connected to the barrier. In a modification of this arrangement, a piston and cylinder are used, connected to an arm of the barrieroperating lever, the counterweight being dispensed with and the bell wheel being chaindriven from the spindle of the lever. In a further arrangement a double-vane rotary device is arranged directly on the spindle of the barrier and is locked in either position by a mechanical detent which is released by the application of hydraulic pressure to open or close the barrier; during the raising of the barrier liquid is also pumped into a closed reservoir containing air which is compressed to supply power to close the barrier if the' electric supply to the pump fails. This subjectmatter does not appear in the Specification as accepted.
