Title: Signal processing circuit
IPC: G11B27/10
Filed: 1976-01-27
Abstract: 1494155 Data transmission; blocking circuits NCR CORP 27 Jan 1976 [21 Feb 1975] 3056/76 Heading H4P [Also in Division G4] A signal processing circuit decodes a data signal waveform, e.g. from a magnetic tape, of the kind having interleaved data and clock signals and provides a signal wherever a clock signal is missing from the data signal waveform. The missing clock pulses may be used to indicate the start of a data group. A data signal waveform of the kind having regular clock pulses spaced by a time 4T, the presence and absence of a data pulse midway between two clock pulses indicating binary 1 and 0 respectively, is applied to input 12. Initially flipflop 18 is set to enable gate 24. A clock pulse passes gate 24 to trigger astable 14 which causes flip-flop 18 to reset for a period 3T. Thus any midcell data pulse passes gate 22, enabled by flip-flop 18, and is fed on line 30 to a utilization circuit. An astable 44 has a period of 5T so that it remains set in the presence of successive clock pulses. To indicate the start of a data group a clock pulse is omitted and may be followed by a data pulse. Thus astable 44 resets to provide a missing clock pulse signal on line 46 and the succeeding data pulse passes through gate 24, which is enabled since flip-flop 18 has been set by astable 14 at a time 3T after the last clock pulse, to set astable 44. Several clock pulses may be omitted, each missing clock pulse being followed by a data pulse. To prevent errors, since the data pulses now pass gate 24, one further clock pulse and the possible following data pulse are both omitted so that a further signal is emitted on line 46 and the next pulse to pass gate 24 is a clock pulse. An astable 34 and a flip-flop 36 clocked by the clock signals passing gate 24 are provided to give synchronized and shaped data output pulses. Specification 1,122,342 is referred to in terms of section 9 of the Patents Act 1949. Regerence has been directed by the Comptroller to Specification 1,122,342.

Title: Gas control valve assemblies having an ignition responsive thermo electric safety device
IPC: F24C3/10
Filed: 1972-01-24
Abstract: 1364015 Piezo-electric igniters; rotary control valve assemblies JOH VAILLANT KG 24 Jan 1972 [3 Feb 1971] 3277/72 Headings F4F and F4T [Also in Division F2] A gas-control valve assembly comprises an ignition-responsive thermo-electric safety device including a safety valve 42, Fig. 11; a pilot valve 7; a rotary handle 2 co-operable with said valves and rotatable from a gas-off first position through an ignition stand-by second position to a gas-on third position; a piezo-electric ignition device 27, Fig. 7; and an impact mechanism 23 co-operable with handle 2 and arranged to strike device 27 on a movement of handle 2; said handle 2 being movable axially to a displaced position when in said second position thereby opening safety valve 42 to release an ignition gas flow, the handle being rotatable in the displaced position to operate impact mechanism 23. Pilot valve 7 is opened on rotation of handle 2 to said second position by a stem 8 engaging a cam 6 on a rotary cup 3, Fig. 2, connected to handle 2. A projection 21, Fig. 7, from handle 2, acts on rotation of handle 2, in the depressed state, between said second and third positions to cock an arm 51, carrying a hammer 35, against the action of a spring 24. A cam-follower 13, Fig. 2, on the cup 3 engages a cam-track 16 on a member 14 so that depression of handle 2 acts via member 14, a spindle 15, Fig. 11, lever 88, and a collar 152 on a tappet 39 to open safety valve 42. If ignition occurs, a thermocouple energizes a solenoid 44, of insufficient power to open valve 42 from the closed state, to hold valve 42 open. Depression of handle 2 when in the ignition stand-by second position is permitted, and the handle is retained depressed during rotary movement from said second position through said third position to a full-on fourth position by coaction of projections 20, Fig. 2, with recesses 19 in a flange of cup 3. Axial movement of handle 2 whilst in the fourth rotational position to the undepressed state allows a spring 54 to move tappet 39 to a position allowing a spring 55 to open a main gas valve 40 by means of collars 152, 45 on tappet 39. The interengagement of cam 13, track 16, spindle 15, lever 88 and tappet 39 prevents valve 40 from being opened during the preceding movements of handle 2. A reverse rotatory movement of handle 2 when undepressed results in closure of all of valves 7, 40, 42.

Title: Improvements in or relating to circular knitting machines
Inventor: WAINWRIGHT CARLYLE HERBERT
IPC: D04B15/32
Filed: 1959-02-02
Abstract: 910,773. Knitting-machines. BENTLEY ENGINEERING CO. Ltd. Feb. 2, 1959, No. 3619/59. Class 74 (2). When an abutment movably mounted on a carrier, in turn movably mounted on supporting means for the needle cams of a circular machine and coupled to a needle controlling cam, is brought into the path of a projection or projections detachably mounted in and projecting from a trick or tricks in a needle bed the abutment is engaged and deflected by the projection or projections, during relative rotation between needle bed and needle cams, and moves its carrier, to alter the position of the cam. When a ring 22 is rotated about the top needle cylinder of a superposed cylinder machine, by the main control drum acting through a wire 19 and against the action of a return spring, one end of a gap 22a in the ring rocks a lever 16 and so rocks a lever 15, carried on the same shaft, into an attitude in which its free end is in the path of bits 3 carried in the tricks of a group of, say, sole needles. The lever 15 is swept on further by the bits into a vertical attitude, Fig. 4, in which it is against a stop, and is maintained there by all the bits 3 as they pass. A slide carrying the levers 16, 15 is thereby raised, against the action of a spring 17, and a pin 8 on the slide abuts against a screw 9 in a block 11 carrying the stitch cam 12 and guard cam 13, and so raises these cams to cause the associated needles to draw longer stitches. By adjustment of the screw 9, the degree of stitch lengthening may be varied. A spring 20 interposed between the wire 19 and the ring 22 will yield, if necessary, to prevent damage. In the bottom cylinder. Fig. 5, the bits 3 are carried in tricks in a flange 29 on the cylinder and levers 41, 35, corresponding to the levers 16, 15 are carried on a slide 42 connected by a link 44 to a block 48 carrying the stitch cam. To vary the degree of stitch slackening, the effective length of link 44 is varied by rotating a screw 45 bearing an eccentric pin 46 which locates the lower end of the link, and the relationship between a slot at the upper end of the link and a coacting pin 47 on the cam block is thus varied. In a modification, Fig. 11, when the lever 35 is forced down by the leading one of two bits 3, a projection 62 on the slide 42 moves from under a lever 59 and allows the lever to swing in towards the cylinder, under the influence of a spring 61, over the top of the projection 62. The slide 42 is thus held depressed until the leading one of two bits 64 acts on a nose 63 on the lever 59 to swing the lever outwardly, allowing the slide to rise again under the influence of a spring 57. The purpose of the trailing member of each of the two bit pairs is to resist any tendency for the trick wall to be forced over by the repeated impact on the leading bits. Specification. 876,794 is referred to.
