Patent GB-1436891-A (GB)
Title: Particle analysing apparatus having non-rectifying clamps
IPC: G01N15/12
Filed: 1973-05-09
Abstract: 1436891 Thresholding pulses COULTER ELECTRONICS Ltd 9 May 1973 [12 May 1972] 22222/73 Heading H3P [Also in Division G1] The pulse processor of a particle analyser having a D.C. level corrector of the type in which the D.C. component is extracted by means of a filter 56, 58 and combined with the signal in opposite sense has a threshold detector 64 to detect the presence of a pulse and to block at 60 the path to the filter during the pulse so that the level correction is not affected thereby. In Fig. 5 (not shown) the filter capacitor is of Miller type and the threshold detector (81) is preceded by an absolute value circuit (51) so that it is effective for both polarities of signal. Where the corrected level is to be different from zero a reference voltage source (S2 in Fig. 8, not shown) may be applied to the integrator amplifier, the thresholder and the absolute value amplifier. In order to remove from the correction path the portion of the end of a signal between the threshold level and the zero level a gate (SW, Fig. 11, not shown) may be controlled by a bi-stable circuit (FF) which is triggered by the leading edge of the signal and restored by a pulse derived from the trailing edge and applied to the bi-stable by a delay. Alternatively, if the maximum duration of the pulse is known the bi-stable circuit may be restored after this duration. The parts of the pulse between the D.C. and threshold levels at the beginning of the pulse is delayed (at D, Fig. 11) before application to the gate. In Fig. 13 the signal is applied to the grid of the first valve 191 of a negative feedback amplifier 191, 192, 193, 194, the latter operating as a load for 193 and providing an output at 213. The signal is passed to a R.C. filter comprising the resistor 224 and Miller capacitor 225 and the resulting D.C. component is fed from the anode of valve 195 to the screen grid of valve 191 to correct the D.C. level. When a signal occurs and the level arises above a threshold value a voltage is applied at 232 which causes diodes 178 to 181 to become conducting and block the path of the filter. The absolute value circuit (Fig. 7) comprises a feedback amplifier 300 supplying rectifiers 305 and 306 directly and through an inverting amplifier 304 respectively. It is followed by a circuit 308 including capactive coupling to prevent lock-out and this is followed by a comparator 81.

Patent GB-317472-A (GB)
Title: Improvements in block printing machines
IPC: B41F1/10
Filed: 1929-07-19
Abstract: 317,472. Armstrong Cork Co., (Assignees of Webster, H. A.). Aug. 17, 1928, [Convention date]. Platen machines. - In block machines for printing designs on linoleum &c., of the kind described in Specifications 304,237 and 312,065, wherein variable designs are printed by a multiple block printing - head composed of sections which are selectively controlled to print as desired, an improved selective control is employed in which the maintenance of the required blocks in printing position is controlled by latches which are preferably operated electromagnetically. Each block section is controlled by a separate latch, and is moved into and out of printing position positively by means of cams, and the electromagnets are energized automatically by electric trip devices. Each printing-head, Fig. 1, is divided transversely into three or more sec. tions 8 carried by a frame 4 which is recipro. cated vertically by a post 5 operated by a cam 7. Each section 8 is attached to a pad 11 carried by four rods 12, Fig. 5, which can slide in a frame 13 attached to the frame 4, and are depressed into printing position against the action of springs 60. A sliding yoke 32 for each section 8 is reciprocated by oscillating cams 31 in the frame 4, and the rods 12 can be secured to the yokes by means of spring-controlled latches 35 which engage under blocks 16 secured by bolts 14 and nuts to the rods 12. The yokes are caused to move downwards relativelv to the frames 4 as the frame is raised out of printing position, and the head 32d of each yoke acts on a block 16 to depress the printing-sections 8, as the frame 4 is lowered. If the section 8 is required to print, an electromagnet 46, Fig. 10, is energized, and a pivoted armature 52 is raised to cause a T-piece 52<c> on it to engage with an oscillating dog 45b which is oscillated by link mechanism from the yoke 32. The armature 52 is moved to the left by the dog, and carries with it a bolt 50 which passes through an aperture in an attachment to a lever 48, and a spring 51 is compressed and tends to move the lever 48 to the left. A latch bar 54, Fig. 15, is moved to the left by the spring 51 when the adjacent block 16 is lowered to permit of this. The block is grooved at the top to receive the latch bar 54. A similar latch bar 54<1> is operated simultaneously to engage the other block 16, and the printing section is thus locked in its lowered or printing position. The catch 35 is simultaneously operated to release the block 16, and the yoke 32 is then raised without carrying the printing-section. This occurs when the frame 4 is in its uppermost position, and it is then lowered slightly to permit of the inking operation. If the electromagnet of a section is not energized, this section remains coupled to the yoke 32, and is not in position to be inked by the inking-roller, nor to be lowered to printing position. After a section has printed it is released from the latch bars 54, 54<1>, by the action of a spring 58, Fig. 10.

Abstract: 1,088,617. Varying compression ratio. W.G. LUNDQUIST. May 26, 1965 [June 30, 1964], No.22473/65. Heading F1B . In an I. C. engine, Fig. 1 (not shown), comprising four radial cylinder blocks, each block including two approximately parallel cylinders, Fig. 5 (not shown), having a common combustion chamber 14, the extent to which a plunger 28 extends into the combustion chamber may be varied to vary the engine compression ratio. Pressurized fluid flows through passages 54, 53 and port 43 to a chamber 39 in which the end of the plunger remote from the combustion chamber is located. This end is formed with a flange 28' which limits inward travel of the plunger. A manually operated valve 59 controls the proportion of pressurized fluid which is returned to the supply via passages 57, 58 and a return pipe (not shown). At starting valve 59 is closed and plunger 1 is forced to its furthest inward position, the supply of pressure fluid being then discontinued. After starting, valve 59 may be partially opened to allow plunger 28 to return to an intermediate portion. Alternatively pressure fluid at a constant pressure controlled by valve (64) Fig. 2 (not shown) may be supplied continuously during normal running, the piston 28 then driven backwards on each compression stroke by an amount adjustable by valve 59.
