Patent GB-105636-A (GB)
IPC: D03C1/06
Abstract: 105,636. Barker, A. F. April 29, 1916. Dobbies: jacquards.-Double-action dobbies and jacquards are adapted to produce centre-shedding by causing both knives or equivalents to act in succession and the pattern surface to indicate for every pick, one knife &c. raising all the healds to the centre-shed position for the beat-up and the other knife &c. then raisine all the healds to be raised to the top-shed position. In a balk-lever dobby, each head A. Fig. 1, is connected by an L-lever B to the balk C, and one knife F first draws all the hooks D to raise the healds to the centre-shed position, us shown. The beat-up and the pattern indication by the lag barrel H then take place, and, it a heald is to be raised, the hook D<1> and a faller G remain lowered, so that the knife F<1> draws the hook D' and a catch on the hook D is engaged by the faller to retain the hook D in the position shown, the balk being thereby moved into a vertical position and the heald being raised to the top-shed position. If the faller G and hook D<1> are raised, the hook D returns with the knife F, the hook D<1> is not drawn, and the heald is lowered to the bottomshed position. If pegs on the lag barrel indicate for raising the healds, the faller G, Fig. 5, is hook-shaped and the indicator needle I acts as shown. If a to-and-fro motion is not given to the barrel H, a give-way device is interposed between the barrel and the faller and comprises a wire J, Fig. 5<a>, having fixed and loose washers K, M with a spring L between them, the washer M acting on the faller G through another loose washer 0 and a wire N. Instead of the balk C, a disk or bowl may be used having a shallow groove engaging a cord &c. connecting the hooks and so mounted that it may be rotated and moved bodily by the hooks to give the desired motion to the heald; a projection on the lower hook co-operates with a stop. on the framework to prevent backward movement of this hook as the heald is moved to the centre-shed position. Crank-disks E, E<1>, Fig. 6, may be employed instead of knives and hooks with a balk C or with the grooved disk. both the crank-disks being actuated at each pick by any of the standard methods such as that employed in the Dobcross dobby. In a jacquard, the hooked uprights D, D', Fig. 9, and knives F. F<1> are actuated as in the dobby, and the dwelling- up device comprises a hook P on the upright D and a bar or knife G<1> which is moved outwards at the required times to allow the hook P to pass it without friction. If the harness neck-band R is attached to the centre of a bowl S, each knife must lift the full depth of the shed, but, if the arrangement shown in Fig. 10 is employed, each knife need lift only half the depth of the shed. Specifications 1790/89 and 11762/89 are referred to.

Title: Cardiac pacers
IPC: A61B5/042
Filed: 1972-03-11
Abstract: 1424355 Synchronous heart pacers KENT CAMBRIDGE MEDICAL Ltd 8 March 1973 [11 March 1972] 11501/72 Heading A5R [Also in Division H3] A synchronous heart pacer has electrodes 7 for sensing P-waves, electrodes 5, 6 for sensing QRS signals, gating means 12 which responds to the signals from electrodes 5, 6, 7 by blocking any similar simultaneously occurring signals so that only a pure P-wave signal without a QRS component passes to an output connection from gate 12 to electrodes 5, 6 and controls stimulation of the heart via electrodes 5, 6, and delay means 15 which introduces an A-V delay between sensing of the P-wave and stimulation of the heart via electrodes 5, 6. The electrodes may be disposed on a catheter 1 for insertion via a vein into the heart so that a tip electrode 5 and electrode 6, 1 cm. therefrom, lie in the right ventricle and electrodes 7, 1cm. apart and 12 cm. from the tip, lie in the atrium. More than two electrodes may be provided for each of the atrium and ventricle, or only one for each with a common indifferent return electrode. Atrial electrode signals pass via a variable gain amplifier 8 to give rise to corresponding pulses at the output of a generator 9. Similarly a generator 11 gives rise to output pulses corresponding to QRS complex signals and these output pulses block in the circuit 12, any output of circuit 9 occurring during a QRS complex. The unblocked pulses from circuit 9 act via control circuits, including the A-V delay circuit 15, on a pulse generator 16 to synchronise ventricular stimulating pulses produced thereby to the natural heart rate. The output pulses of generator 16 pass to an output amplifier 19, having a variable gain giving 20 mA. maximum amplitude pulses, via an inhibiter 18 which inhibits ventricular stimulating pulse generation for a period, e.g. 360 m.sec., after each detected QRS signal, which period extends over the T-wave. If the natural P-wave rate rises above an upper rate limit, the pacemaker reverts to a mode in which stimulating pulses are normally produced at said upper rate. If the natural P-wave rate falls below a lower rate limit, the pacemaker produces stimulating pulses at said lower rate. In a modification. Fig. 4 (not shown), a circuit may be selectively switched to a mode in which, when the pacer operates at the upper rate limit mode, the circuit omits a generated stimulating pulse each time this pulse falls behind the corresponding preceding P-wave by more than a predetermined amount to re-synchronise the circuit to the natural heart beat. Amplifier 19 includes an optical link for electrical isolation purposes. The timing of the various pulse lengths and spacings may be effected by use of multivibrator circuits or by using digital circuits with clock counters. A direct connection (not shown in Fig. 1) between circuit 11 and generator 16 produces a demand-mode of operation.
