Title: Improvements relating to pulse generating circuits
Inventor: GRAFF-BAKER WILLIAM SEBASTIAN
IPC: H02M1/02
Filed: 1952-05-21
Abstract: 738,002. Pulse-generating circuits. BRITISH THOMSON-HOUSTON CO., Ltd. May 20, 1953 [May 21, 1952], No. 12864/52. Class 40 (6). In a pulse generator of the type in which energy is stored in a pulse-forming network and is periodically discharged into a load a saturable reactor which has a very small inductance when the core is saturated is connected in series with the discharge circuit thus preventing a rise of reverse voltage across the switching device or delaying such a rise until the discharge device has de-ionized. Fig. 2 shows a pulse generator in which the pulse-forming network a is charged from a voltage source and is periodically discharged through the primary of transformer d when the gas-discharge tube c is fired, the transformer d serving to match the load to the pulseforming network a. The saturable reactor b is in its unsaturated state when network a has been charged so that when tube c is fired the reactor b presents a high impedance until the current flowing through it causes it to saturate and present a very small impedance. At the end of the generated pulse if there is a residual reverse voltage in transformer d or network a the current flow in reactor b rapidly brings it to its high-impedance state so that the reverse voltage is dropped across reactor b instead of across tube c until after a time delay the reactor again saturates. The reactor may be connected in the anode circuit of the tube c. In a modification shown in Fig. 3 a pulse is generated to fire an ignitron e the output current being limited mainly by the saturable reactor band in which the network b, g reduces the rate of rise of the reverse voltage appearing across the discharge tube c at low pulse recurrence fre. quencies. In a further modification, the Figure (not shown), the saturable reactor has an additional winding which is fed through a choke with polarizing current from a D.C. supply so that when the discharge tube is triggered the reactor is already in its saturated condition and the network immediately discharges into the load. The rate of change of flow which can be controlled by the polarizing voltage supply can be made relatively small with small eddy current losses in the core. Specification 585,359 is referred to.

Title: Means for the spray painting of textile bobbins and the like
IPC: B05B13/02
Filed: 1951-06-02
Abstract: <PICT:0718426/III/1> <PICT:0718426/III/2> In a means for spray painting textile bobbins and the like, the bobbins are placed on a travelling conveyer, by which they are fed through a spraying zone and subsequently through a drying zone, and, whilst passing through the spraying zone, being rotated by contact with a driving belt passing round a displaceable pulley, so as to cause their whole circumferential surface to pass before a spraying device, such contact also causing diplacement of the pulley and in consequence opening a control valve for the spraying device, the return movement of the pulley allowing the control valve to close.  A flat-link chain 1 passes round three sprockets 4, 5, and 6 and is driven by sprocket 4, Fig. 1. Alternate links of the chain 1 carry upstanding pins 3 over which bobbins are placed as the pins move up the inclined portion C.  As the bobbins move along the horizontal portion A they pass a spray device 9 and under a fume extractor 8, and then on to an infra-red drying unit 10.  At the end of the horizontal run the bobbins fall off pins 3 into a receptacle.  At the spraying zone 9 are two pulleys 13 and 14 on spindles 11 and 16, Fig. 6, spindle 11 being carried in the outer end of a radius arm 12 pivoted about spindle 16.  An endless belt 15 encircles the two pulleys 13 and 14 and is driven by pulley 14.  Normally the belt 15 is inclined to the conveyer chain 1 and has one portion lying in the path of the bobbins, spring means (not shown) holding the arm 12 in this position, and allowing these parts to be displaced by contact with an advancing bobbin, and causing their return to the normal position after each bobbin has passed.  A control valve 19 in an air-supply to the spray is inoperative when the belt 15 is over-lying the conveyer, but the air-valve 19 is opened when arm 12 is displaced by a passing bobbin to cause the spray to come into action.  As the bobbins contact the moving belt 15 they are rotated about their fins 15 while being sprayed.

Title: Improvements in or relating to strip feeding and severing apparatus
IPC: B65H35/10
Filed: 1944-07-10
Abstract: 581,465. Feeding webs. WILLIAMS, W. P. (Standard Register Co.). July ]0, 1944, No. 13183. [Class 100 (ii)] [Also in Group VIII] A device which is especially applicable for severing printed strips 4 provided with weakened lines into sheets which are delivered on to an inclined table 7 is constructed with a pin-wheel feed roller 8, Fig. 6 or friction feed rollers which are driven intermittently to advance the strip, and the severing is effected by clamping the strip intermittently by means of clamping bars 13, 14, normally separated by springs 15, and moved into contact by an oscillating beam 27 operated by a cam 26 on a roller 16. While each strip is held clamped it is severed along the line of weakness by the action of pads 18 on rollers 16, 17 which pull on the strip. The rollers 16, 17 normally permit the strip to pass freely through them. If desired only one pad 18 may be used. The feed rollers are driven from a motor which by a belt-and-pulley drives a gear 24 geared to a large wheel 25, Fig. 5, on the shaft of roller 16. The wheel 25, drives the roller 8 by a change-speed gearing, so that sheets of different lengths may be cut, and this gear train comprises a driving-gear 29, Fig. 4 (not shown), which drives a shaft 30 of the gear train by a friction clutch which permits slipping of the clutch when a pawl 45 operated by a cam 47 on the shaft of the roller 16 engages a notch 33 in a disc 32 secured to the driven shaft 30 of the gear train.

Title: Improvements in or relating to apparatus for periodically interrupting one or more electric signals
IPC: H04M19/02
Filed: 1952-05-26
Abstract: 722,550. Automatic exchange systems. GENERAL ELECTRIC CO., Ltd., FORBES, W. A., and BURBIDGE, T. W. March 10, 1953 [May 26, 1962], No. 13299/52. Class 40 (4). In a small exchange the usual ringing machine is replaced by a chain of relays, one or more of the relays releasing more than once in a cycle of operations. When busy tone, ringing current or tone, or a time pulse is required contact MS closes to operate a chain of relays A, B, C, D, all of which are slugged to operate slowly. Operation of C applies busy tone to lead BT and energizes RR to apply ringing current and ringing tone respectively to leads R1, RT1, when A falls back to release RR and disconnect supply to leads R1, RT1. Release of A restores B slowly to reoperate RR to supply leads R1, RT1 again until B restores C, when busy tone is removed from BT. C re-operates A so that A, B, C, D re-energize before D can fall back to energize E which locks up and change over the ringing current and tone supplies from RT1, R1 to RT2, R2. The half-cycle then repeates with a pulse on lead TP, the relays A-E releasing slowly in turn.
