Title: Improvements in or relating to an apparatus for supervising the action of the heart
IPC: A61B5/0245
Filed: 1959-12-11
Abstract: 911,078. Heart-testing apparatus. SIEMENSREINIGER WERKE A.G. Dec. 11, 1959 [Dec. 12, 1958], No. 42284/59. Class 81 (2). An apparatus for checking the action of the heart has means for receiving heat impulses and, after each impulse, preparing a circuit for a period during which the following pulse is anticipated. If this subsequent pulse occurs before or after the expected period, a circuit is completed to give an audible warning. Heart impulses are received through the usual electrodes and then passed through suitable shaping networks. Relays A, C are energized by these impulses and contact a is closed for the duration of each pulse while contact c is opened by the pulse and remains open until the end of the period during which the subsequent pulse should be received. A relay B is energized to close its contact b from the receipt of one impulse until the anticipated commencement of the subsequent impulse. If pulses are received with correct timing contact c will remain continually open and b will be open when each pulse is received. If, however, a pulse arrives early it will close a before b has opened, so completing a circuit to the warning device 21. On the other hand, if it arrives late, contact c will have closed and completed a parallel circuit to the device 21.

Abstract: 1,095,693. Self-sustaining gear-chain hoists. C. H. HEWITT. Oct. 15, 1965, No. 43796/65. Heading B8B. A manually operated chain hoist supported from overhead by a ring 16 comprises a chain engaging sprocket within the casing 10 and connected through reduction gearing to an operating handle 14 which includes a selective pawl and ratchet mechanism for driving the chain sprocket in either direction, the sprocket being prevented from rotating in the hoist lowering direction, due to a load on the hoist, by a freewheel device 48, 55. The latter device comprises a ratchet wheel intermediate two friction discs all freely mounted on the drive shaft (46) Fig. 3 (not shown), driven by the handle (14). The said shaft threadedly receives a nut 51 on which the handle 14 is mounted and when the nut is threaded onto the shaft by movement of the handle 14 in the load raising direction, the nut clamps the friction discs and ratchet wheel against a drive disc integral with the said shaft whereupon the ratchet 48 is driven in its free-wheeling direction past pawls 55. For lowering a load the handle ratchet device is reversed and handle operation unscrews nut 51 whereupon ratchet wheel 48 is frictionally released from the drive shaft until the shaft has turned sufficiently to screw the nut 51 up into engagement with the discs and ratchet wheel. The pawls 55 are spaced such that they each engage teeth on wheel 48 at half tooth pitch intervals. Each pawl is tipped with a resilient material 61 to reduce engagement noise when free wheeling.
