[Also in Division F2] A cardiac valve prosthesis is combined with an instrument for fixing it in position in the heart, the prosthesis having needles for penetrating heart tissue and the instrument having claws 9 for engaging recesses 7 in the prosthesis and means for moving the claws and the needles to cause the needles to penetrate heart tissue. The valve comprises an annular valve seat 1 and a valve ball 2 retained by a cage 3. An annulus 5 carrying two circumferential rows of needles is slidable on the valve seat 1, the needles of the inner row being longer than those of the outer row and engaged in curved channels 6 in the seat. The instrument comprises a washer 8 with claws 9, which in use are caused to engage recesses 7 in the needle-carrying annulus 5 on rotation of the washer by pulling a rod 13 out of a handle 12 of the instrument, and a cylindrical holder 11 for the valve seat. On forcing a lever 15 of the instrument towards the handle 12, the washer and holder approach one another. When the valve is placed on the holder 11 and located in the heart the lever 15 is operated to cause the annulus 5 to approach the valve seat 1 so that the larger needles pass through the curved channels 6 which curve them so that they are directed towards the shorter needles as they penetrate heart tissue. The instrument may be operated in reverse for detaching a valve from the heart.

[Also in Division G3] A no-break standby supply arrangement for a load 88, which is normally energized over an inductor 87 and a line 11 from a primary A.C. line 86, comprises an inverter 10 which is connected to the load 88 by way of a voltage regulating system 23, 24, 26 (see Division G3); the inverter 10 derives its input from a charger 90 which is connected to the A.C. line 86 and which also charges a battery 11, a synchronizing unit 92 being provided so that the inverter output voltage is in phase with the output voltage on line 11. Thus, if the primary supply fails the battery 91 supplies the load over the inverter 10; if the voltage on line 11 should fall, the inverter commences to supply energy to the load and aids the primary supply; in addition, if the load voltage becomes too high the inverter operates regeneratively to charge the battery 91 and aids the charger 90. The inductor 87 isolates the load 88 from the effects of a short-circuit on the line 86.

In manufacture (Fig. 7) flat blanks RB0 for the clamping elements are first cut from a steel strip, a residual strip C0 being left, with cut-out C1 for strip feeding. Secondly, the element is partially bent to shape, relief-stamping of spring finger RB8 being undertaken also, in the case of socket contact. Thirdly, the body portions are attached, arms RB4 of the clamping elements being bent around them and fixed in position by riveting of clamping lugs B 1. At this stage the contact assemblies are connected by the residual strip C0, and can be coiled on to a drum for storage. When required, a contact is placed between clamping jaws (V1, V2, Fig. 10, not shown), crimping jaws connect its end to a wire, and simultaneously a blade severs portion C2, thus freeing the contact from the residual strip C0.

Abstract: 1,248,240. Transistor comparator and pulse circuits. WESTINGHOUSE ELECTRIC CORP. 30 Dec., 1968 [2. Jan., 1968], No. 61583/68. Heading H3T. [Also in Division H2] Apparatus for matching two voltages establishes two different values of opposite polarities representing respectively a first voltage minus a second voltage and the second voltage minus the first voltage and from these produces a first output when the first voltage exceeds the second voltage and a second output when the second voltage exceeds the first voltage. The first and second voltages are of a bus-bar and a generator and are connected respectively to the primary windings of. transformers 201, 224. Each transformer has two secondary windings producing voltages which are rectified and subtracted so as to produce two difference voltages at leads 217, 236 which are applied to the bases of transistors 219, 238 respectively. One or other of these transistors is rendered conductive according to whether the generator voltage is less or greater than a predetermined amount. Conduction of transistor 219 or 238 renders transistor 270 or 334 conductive applying one signal to an AND gate connected to the base of transistor 279 or an AND gate connected to the base of transistor 326. A timing device comprising a unijunction transistor 403 and a flipflop device having transistors 291, 292 produces a signal in the form of pulses to both AND circuits simultaneously, the mark space ratio of the pulses being determined by capacitor 357 and resistors 354, 355, 356. When an AND gate receives two inputs simultaneously, the associated output transistor 279 or 326 conducts energizing either relay 89 or 94 so as to apply the requisite correcting signal to bring the generator voltage to within the predetermined amount, set by potentiometer 264, of the bus-bar voltage. When this latter condition applies transistor 255 conducts so rendering transistor 401 conductive, thereby to produce a signal on terminal 371 to enable the synchronization operation of the generator on to the bus-bars.
