Title: Heart pacers
IPC: A61N1/365
Filed: 1973-03-09
Abstract: 1416563 Demand pacemakers AMERICAN OPTICAL CORP 9 March 1973 [9 March 1972] 11620/73 Heading A5R [Also in Division H3] An atrial and ventricular demand heart pacemaker has ventricular pulse generating means T9, 65 for generating a ventricular stimulating pulse at the expiration of a ventricular timing interval, synchronising means T6, T7, T8 responsive to synchronise the ventricular pulse generator to the beating action of the patients' heart, timing means T10, 58, 62 responsive to the operation of the synchronising means for controlling an atrial timing interval, means 62 for adjusting the duration of the atrial timing interval, and means T11, T12 responsive to the expiration of the atrial timing interval for generating at most one atrial stimulating pulse for each ventricular beating action of the patients' heart. The synchronising means and the ventricular stimulating pulse generator are identical to the circuits disclosed in Applications Nos. 88/73 and 1024/75 but the atrial pulse generator comprises an atrial timing circuit controlling conduction of transistor T14 to discharge a capacitor 82 through the primary of transformer 80 to produce an atrial stimulating pulse at electrodes E3, E4. The atrial timing interval is determined by the charging of a capacitor 58 through a resistor 62, adjustable to alter this interval, and is prematurely terminated whenever a spontaneous ventricular beat is detected, or a ventricular stimulating pulse is produced, by discharge of capacitor 58 through transistor T10, the voltage timing circuit is not reset by transistor T10, the voltage on capacitor 58 reaches a level to fire transistors T11, T12 to discharge itself therethrough giving rise to conduction of transistor T14 and production of an atrial stimulating pulse. A variable resistor 95 sets the atrial pulse width. The circuit comprising transistors T15, T16, resistors 92, 94, 95 96, 97 and capacitor 93 act to prevent transistors T11, T12 turning off following discharge of capacitor 58 therethrough until transistor T10 conducts again to discharge capacitor 58 completely. Thus production of multiple atrial stimulations between successive ventricular beats, either or both of which may be spontaneous or stimulated, is prevented even though the atrial timing interval may be adjusted by resistor 62 to be less than half the ventricular timing interval, which is adjustable by resistor 35.

Abstract: 712,245. Turret-lathes. ARON, E., BANNING, A. J., and PULMAN, W. E. R. May 9, 1952 [May 18, 1951], No. 11723/51. Class 83 (3) Mechanism for reciprocating a turret slide and for indexing a turret theron 'in an automatic lathe &c. comprises continuously-actuated means for moving the slide in its working movement, over-riding means for withdrawing the slide away from the work, separate means for indexing the turret after withdrawal and timing means for operating said over-riding means and indexing means consecutively in timed relationship with the operation of said continuously actuated means. Turret indexing is effected from a shaft 14, Fig. 1, and gearing 23, 24 described in Specification 712,243, [Group XXIV]. The shaft 14 is rotated intermittently by Geneva mechanism 21, 22, from a back shaft 11, a sleeve 18 on which is rotated through a one-revolution clutch timed from a cam-shaft 10, Fig. 2, at the front of the machine. A face cam 28, Fig. 1, is rotated intermittently by gearing 19, 27 from the sleeve 18 and engages a follower roll 45, Fig. 2, at the end of a pin 44 carrying a sector 43 for moving the turret-slide 25 through the rack 41. The pivot pin 44 passes through the upper end of a link 49, Fig. 6, the lower part of which is pivotally connected by a pin 50 to a cage 51 for an epicyclic gear train. The end of the link is provided, beyond the connection 50, with a roller 65 engaging a slot 52, Fig. 2, in a fixed part 53. A cross-shaft 12, driven from camshaft 10, rotates a wheel 62 of the epicyclic train which, through a compound wheel 63, 61, and a wheel 68 (not shown in Fig. 2) rotates wheel 64 and a connected cam-disc 48. The latter engages a follower roller 47 on an arm 46 forming a downward extension of the sector 43. The cam 48 rotates continuously and feeds the turret slide whereas the cam 28 over-rides this movement to withdraw the slide rapidly for an indexing movement. A spring 57 and cranked lever 54, Fig. 6, assist the withdrawal. The epicyclic gear ensures that the timing of the feed cam is not affected by the movement of the pivot 44, the cam 48 and follower 47 moving around together to maintain their proper relationship for a part of the cycle of movement. A locking mechanism for the turret is also described.

Abstract: 810,598. Automatic gramophones. BIRMINGHAM SOUND REPRODUCERS Ltd. June 5, 1957 [April 20, 1956], No. 12193/56. Class 40 (2). In an automatic gramophone wherein the setting-down position of a pick-up is controlled by a movable stop which is operated by a detent member tripped by a record falling to the turntable and is abutted by a locator member connected to the pick-up arm, the need to unclutch the locator member from the pick-up arm (to allow the latter to swing further inwards during record playing) is avoided by provision of means to space the stop clear of the locator member after the pick-up has been located. As applied to the apparatus described in Specification 766,048, the resetting lever 42 of that Specification is replaced by a lever 52, Fig. 4, moved outwards against its spring 55 by a cam pin 54 on the usual one-revolution gapped control gear 9 as soon as the pick-up has been set down, whereby a spring extension 56, overriding the spring 41, Fig. 10, moves the stop lever 38 to the position of Figs. 10 and 17 clear of all abutments 25 ... 27 of the locator member 24, which is permanently fixed on the vertical pick-up arm spindle (the Provisional Specification refers to a pin-and-slot connection here). The detent 42 is stepped as in Specification 810,599. General operation.-A cam 10 on the onerevolution gear 9 reciprocates a plate 8 by engagement with lugs 11; during record-playing the lever 52 and cam pin 54 hold the gear 9 in its inoperative position with the plate 8 at its right-hand extremity. As soon as the gear 9 is engaged with its drive, the edge 16 of a slot in the plate 8 is withdrawn from the upper arm of an L-shaped lever 13 whereby a spring 14 lifts its lower arm 17 to lift the pick-up arm by means of a push-rod 23; the stop 38 is released by the lever 52 and assumes its innermost position as in the earlier Specification; the edge 35 of a slot 29 in the plate 8, engaging a pin 28 on the locator member 24, swings the pick-up arm outwards; and a friction bar 31, pressed against the plate 8 by a leaf-spring on the ends of guide pins 32 slidable along a slot in the plate 8, is held by a fixed bracket 12 so that it moves to the right-hand end of the slot. The stop 38 is then set as before by the falling record, and as the plate 8 moves to the right, the friction bar 31 pushes the pin 28 until stopped by the appropriate abutment 25 ... 27 meeting the stop 38, whereafter the plate 8 slides over the bar 31. Finally, as the edge 16 contacts the lever 13 to lower the pickup on to the record, the cam pin 54 engages the lever 52 to retract the stop 38.

Abstract: 991,737. Tyre repairs. FIRESTONE TIRE & RUBBER CO. March 28, 1963 [April 9, 1962], No. 12296/63. Heading B7C. A tyre sealing plug comprises a rubbery laminate spirally wound upon itself and forming a convoluted member (Figs. 9, 11). The laminate may comprise a layer of vulcanized rubber sandwiched between two layers of only partially vulcanized rubber; its outer surfaces are thus vulcanizable. The plug is wound when required from a triangular piece of laminate (Fig. 8, not shown) and shaped to produce a tapered plug. A film of self-vulcanizing liquid is applied either to the laminate before rolling or to the finished plug. The film initiates vulcanization of the laminates at room temperature and is itself vulcanized by migration of the necessary ingredient from the laminate. The plug is drawn into an outwardly tapering hole Fig. 2) in a tyre 1, and is trimmed (Fig. 4). A heated clamp is applied (Fig. 5, not shown) causing the plug to seat in the hole, and the convex face 16 is buffed to smooth off the plug around the inner edge of the hole, to leave no laterally extending " head " on the plug (Fig. 6, not shown). Finally a pre-vulcanized patch 19, incorporating fabric reinforcement, is applied, and with the tyre inflated (Fig. 7) the convex inner end of the plug is flattened. The tyre may be retreaded over such a repair. Fig. 12, not shown, illustrates a plug of oval cross-section. Specification 991,738 is referred to.
