Patent GB-1030380-A (GB)
Title: Cardiac pacer
Inventor: KELLER JOHN WALTER
IPC: A61N1/368
Filed: 1964-11-24
Abstract: 1,030,380. Electromedical apparatus. CORDIS CORPORATION. Nov. 24, 1964, No. 47726/64. Heading A5R. An electrical cardiac pacer circuit comprises an input responsive to a P-wave signal generated by the heart on contraction of the atrium to produce a trigger signal, which is delayed by a time corresponding to the normal interval between the auricular and ventricular systoles, and an output for producing a stimulation signal, the input and output being connected by means including an oscillator for causing the output signal to be synchronized with the delayed trigger signal. The heart is connected by a sensing electrode so that the P- wave signal is transmitted through amplifiers 10, 20 to a one-cycle multivibrator delay circuit 30. The transistor T 3  of the multivibrator is normally conducting and reception of the amplified signal causes the multivibrator to reverse slates so that the transistor T 4  conductor for a period determined by a capacitor C 5  and a resistor R 5 . During this period the multivibrator is insensitive to further signals from the heart. While the transistor T 4  conducts, a signal is transmitted to the blocking oscillator 40, the positive initial pulse being blocked by a diode D 2  and the negative pulse at the end of the conduction period of the transistor T 4  passing to the oscillator 40 as a delayed trigger signal. The oscillator 40 comprises a free-running multivibrator in which transistors T 5 , T 6  normally alternately conduct to provide stimulating impulses of a desired frequency. During normal operation, the blocking oscillator 40 receives the trigger impulse when transistor T 6  is conducting to render the delay circuit 30 inoperative for a predetermined period. However, reception of the trigger impulse when transistor T 5  conducts causes transistor T 6  to conduct, thus reducing to a desired new value the period of the oscillator 40. The stimulating impulse is transmitted via a pulse generator 50, comprising normally cut off transistors T 7 , T 8  arranged in a common feedback loop, and an amplifier 60 to the ventricle. The shunt transistor T 10  prevents a signal derived from the stimulating impulse received by the ventricle from influencing the operation of the circuit. If the P-wave signals or the input circuits 10, 20, 30 fail, the oscillator 40 provides stimulating impulses at its natural frequency, e.g. 60 pulses per minute. The circuit and batteries B 1  to B 5  are enclosed in a casing implanted in the patient's body, the casing being conductive to provide a local ground connection 61. The batteries are associated with a charging circuit (Fig.3 not shown) including a full-wave diode rectifier and an inductance, in which a rectified changing current may be produced by applying an alternating magnetic field to the outside of the body.

Abstract: 1,249,651. Rotary positive-displacement pumps. ABEX CORP. Oct.14, 1968 [Nov. 27, 1967], No.48630/68. Heading F1F. In a hydraulic-pump of the outwardly-sliding radial-vane type, to sustain contact between a fixed cam-ring 14, Fig. 3, and the vanes 32 of a rotor 28 pressure is exerted on a piston 76 associated with each vane and a portion of the radially-inner-most edge of the latter in register with a bore 77, Fig. 1, in said piston communicating with an annular chamber 71 to which a proportion of the working fluid e.g. oil, is admitted through said bore whenever the respective piston is retracted by the pressure in the end 48 of a slot for the corresponding vane exceeding that in the chamber as a consequence of a groove 67 in the vane coming into register with V-grooves 90, 91 in a checkplate 10 while the vane approaches either of two outlet, or pressure, ports 51, 52. The grooves 90, 91 restrict the flow of fluid therethrough and render the pressure in each space or pocket 40 between the vanes approaching the ports 51, 52 substantial by constant, the grooves 90 being preferably connected hydraulically to outlet passageways 54, 55, Fig. 2, between inlet passageways 47 by flow-restricting passageways 88. The pump shown can be reversed by rotation of the cam ring through 90 degrees relative to the checkplate 10 and a further check-plate 19 defining further inlet passageways 47. If the pump is rendered irreversible the grooves 90, 91 are furnished only on the leading side of each of the outlet ports, the grooves being otherwise provided on either side of each port, as shown. To effect pressure balancing dummy V-grooves (93), Fig. 11 (not shown), may be formed in the check-plate 19, which contains inlet, or suction, ports 45, 46 in axial alignment with similar ports 43. Additional inlet ports 50 are provided in each of the check-plates to permit fluid to enter the ends 48 of the slots when the vanes move outwardly. Recesses 59, 60 in the cam-ring overlap the outlet ports and facilitate reversal of the pump. The trailing side of each vane may contain a groove 82 to effect communication between the end 48 of the respective slot and the associated pocket when the vane projects farthest from the rotor, Fig. 5 (not shown). In a second embodiment, Fig. 14 (not shown), the pistons 76 are dispensed with, pressure being exerted on the radially-innermost edges of the vanes (101) by fluid in annular channels (104) at opposite ends of the rotor intersecting the aforementioned ends of the slots for the vanes. The channels (104) are connected to the grooves 90, 91 and the ports 51, 52 by passages (107) containing non-return valves (108) and orifices equivalent in effect to the passageways 88.
