Patent GB-2076665-A (GB)
Title: Exercising apparatus
IPC: A63B21/008
Filed: 1980-06-02
Abstract: An exercising device comprises a cylinder 1 having a handle 14 fixed to one end, a piston 7 movable in the cylinder and carried at one end of a piston rod 13 extending through a gas-tight seal in the end wall of the cylinder opposite the handle, and a further handle 20 fixed to the other end of the piston rod, the cylinder containing a pressurised gas and the piston having a narrow bore 7A through which the gas can pass during compression and expansion of the device. Since the effective area of the piston on the side opposite the piston rod is greater than that on the other side, the high pressure gas produces a net resilient force on the piston tending to expand the device. The passage of gas through the bore in the piston provides a damping effect which must be overcome when the device is compressed and which slows the expansion of the device when the handles are released. <IMAGE>

Filed: 1980-08-18
Abstract: Shoes 1, 2 can be applied to a rotatable drum 3 by an hydraulic actuation system acting on the leading ends of both shoes for normal service braking so that the brake acts as a "two-leading" show type and by a mechanical actuation system which acts only on the leading end 1L of one shoe 1 with the thrust from that shoe being transmitted to the leading end of the other shoe 2 so that for parking or emergency braking the brake acts as a "duo-servo" type. Several embodiments are disclosed. As shown the system comprises two hydraulic pistons 1p, 2P, first and second abutments 1A, 2A are provided against which the trailing ends 1 T, 2T of the shoes 1, 2 are adapted to rest. The abutment 2A is fixed but the abutment 1A includes an auxiliary hydraulic piston 5 which is adapted to be urged against a fixed stop 7 by hydraulic pressure. The mechanical system comprises an expander 8 acting on end 1L-the drag reaction of shoe 1 being transmitted to shoe 2 via a strut 21. Mechanical actuation may alternatively utilise a spring, or a wedge and roller actuator acting on piston 1P (e.g. Fig. 4). Embodiments are disclosed in which the brake functions as a 'two-leading' shoe type and a 'duo-servo' type for both directions of rotation. Details are given of manual and automatic wear adjustment (Figs. 6, 14). <IMAGE>

Title: Two-pulse Tachycardia Control Pacer
IPC: A61N1/362
Filed: 1981-03-25
Abstract: There is disclosed an externally programmable pacer for controlling tachycardia (rapid beating) by interposing a pair of pulses between heart beats. The first pulse is generated a short time t, known as the "initial delay", after confirmation of tachycardia (detection of four too- rapid heartbeats). The initial delay is scanned" (i.e. decremented in 6 msec steps) from one extreme to the other. The second pulse is generated after a further time T, known as the "coupled interval", following the first pulse, and the coupled interval is scanned as well as the initial delay. Also, the time intervals T, T which are successful in terminating tachycardia are stored so that upon confirmation of another tachycardia event, the previously successful time intervals are the first ones to be tried. The unit also may be programmed to treat normal rhythms as tachycardias, whereupon the stimulating pulses may actually cause tachycardia to be induced, so that the parameters which are programmable can be adjusted by the physician for optimum performance. <IMAGE>
