Title: Current pulsing circuit which is sensitive to current changes
Inventor: IRELAND REGINALD ERNEST
IPC: H01H51/34
Filed: 1959-05-22
Abstract: 936,274. Road traffic signals. W. E. O'SHEI. Jan. 8, 1960 [May 22, 1959], No. 17442/59. Class 118. In a turn indicating system for flashing lamps R1, R2 or L1, L2 in combination with pilot lamp PR or PL, respectively, the flasher unit comprises a relay A having a low resistance starting winding 2 and a high resistance delay winding 1 which is connected in series with a condenser 3, the winding 1 and condenser 3 being normally short-circuited by the relay contacts A1. Upon operation of the selector switch S to the right, say, a heavy current flows and the lamps R1, R2 and PR are illuminated, the relay operates immediately and the opening of contacts Al douses the lamps. Condenser 3 then charges in series with the relay windings and the lamps, the latter remaining unlighted, and the charging current through the delay winding 1 keeps the relay A energized until the condenser 3 is nearly charged. At this point the current falls below the holding value and the relay A releases. Closure of contacts A1 completes the starting circuit again thus re-lighting the lamps. Simultaneously, the condenser 3 discharges through the delay winding 1, thus producing a field in opposition to that produced by the battery current flowing in the starting winding 2 and delaying the closure of the contacts A1 until the condenser 3 has discharged sufficiently to allow the starting winding field to attract the relay armature. The contacts A1 then open and the cycle is repeated. If the load is increased or decreased, the frequency of the pulsing will change accordingly, and if the load current falls below a predetermined value the starting winding field will be insufficient to operate the relay. The circuit is so designed that this predetermined value of load current is greater than that taken by either R1 and PR or R2 and PR, but less than that taken by R1, R2 and PR, so that if a lamp R1 or R2 burns out the pulsing circuit will not start when switch S is thrown to the right, and pilot lamp PR will remain continuously alight to indicate the fault condition. A resistor may be switched into circuit under control of the side light switch (not shown), in series with the lamps so as to dim them during the hours of darkness.

Title: Improvements in or relating to prime mover-alternator sets and control systems therefor
IPC: F01D17/26
Filed: 1944-09-14
Abstract: 599,432. Fluid-actuated servomotorcontrol systems. WESTINGHOUSE ELECTRIC INTERNATIONAL CO. Sept. 14, 1944, No. 17593. Convention date, Sept. 15, 1943. [Class 135] [Also in Groups XXVI and XXXV] A governor system for a turbo-alternator or other prime mover-alternator set comprises in addition to the usual speed responsive means for controlling the operating fluid admission valve of the prime mover, means which control the valve in accordance with the phase difference between the alternator voltage (or a representative pilot voltage) and a reference voltage. As shown in Fig. 2, phase control of the admission valve 31 of a turbine ST driving an alternator AL and pilot voltage generator PG is effected by a solenoid 7 acting on the spring of a speedresponsive governor (not shown) and energized in series with a variable resistance 24 from a source 26. The mechanism for actuating the admission valve in dependence upon engine speed and current in solenoid 7 may comprise (1) an engine driven governor 90, Fig. 8, the spring loading on the fly weights 91, 92 of which is controlled by a link 96 operated by the solenoid ; (2) a fluid pressure servomotor 52, 53 having, rod 55 connected to the admission valve and through linkage 6, 54, 58 to a followup member 76 ; (3) a pilot valve 63 for the servomotor, and (4) a governor-controlled adjustable relief valve 81, 84 in the fluid system of the servomotor. Fluid enters the mechanism by a port 65 and leaves by a duct 69. When the set is running at correct speed and phase the pilot valve assumes under the combined effects of springs 74, 75 and the fluid pressure within space 71, the position shown so as to maintain the ports 61, 62 of the servomotor closed. If, however, either the governor speed, or its loading due to solenoid 7, changes, the relief valve modifies the pressure in the system and causes the pilot valve to move in such a direction as to open the appropriate port 61 or 62 and cause the servomotor to apply a correction to the admission valve setting, the follow-up mechanism restoring the pilot valve to its initial position as correction is effected. In a modified arrangement, the phase responsive control of the servomotor is effected by a torque motor operating through a fluid pressure transformer on the follow-up mechanism, the motor torque being proportional to the phase difference between the reference and pilot voltages and controlling the fluid pressure. The response of the control system may be speeded by the accelerationresponsive anticipatory systems described in Specification 599,433.

Patent GB-1113516-A (GB)
Title: Contacting fiber bonding
Inventor: GREEN HENRY CORY
IPC: D06C29/00
Filed: 1966-04-22
Abstract: Contacting fibres of thermoplastic material are bonded by exposing the point of contact of the fibres or yarns to a light pulse, preferably of between a few hundred microseconds and a few milliseconds duration, from a high energy light pulse source spaced therefrom.  The term "fibre" includes monofilaments multifilaments, threads and yarns.  Preferably, the light pulse source is a photoflash lamp comprising a transparent tube (14), Fig. V (not shown), e.g.a quartz tube of coiled or helical configuration, containing a rare gas (16), e.g. xenon or argon, sealed therewithin and having electrodes (15) sealed through the ends therof.  The tube may be surrounded by a jacket containing a material, e.g. a liquid, having light filtering characteristics.  The light may be focussed on the material to be bonded by mirrors or reflecting surfaces, e.g. a helical tube may be surrounded by a polished aluminium reflector to concentrate most of the available light along the axis of the lamp helix, the material to be bonded being placed inside the cylinder formed by the lamp.  Alternatively, a moving sheet of fabric may be continuously illuminated by light pulses. Nylon stockings mounted on boarding forms are treated by helical lamps positioned around the forms.  An electrical actuating circuit for the photoflash lamp is described, Fig. VI (not shown). In a modification, the light pulse is produced by conventional photoflash bulbs.  The fibres may be pretreated with a light absorbing material, e.g. carbon black, benzyl alcohol, colloidal silica, certain metal oxides or sulphides, or a resin coating, at the point of contact thereof to increase the absorption of light energy over the normal absorption by the untreated fibre or yarn surface.  Alternatively, the fibres may be treated with water or steam to increase the light absorption.  In Examples, a nylon stocking knitted fabric is first tensioned or placed between glass microscope slides to ensure that the intersecting filaments are in contact.  Each intersection may be bonded, Fig. III (not shown), or only random intersections are bonded, Fig. IV (not shown).  Specified fibres are glass, metal, e.g. aluminium, iron and copper, and organic fibres, e.g. vinyl, expoxy, acrylic, urethane, polyester and nylon resins.  The invention is also applicable to butt joining or splicing fibres in an angular or scarfed manner and with or without pretreatment, or to forming a non-woven fabric, e.g. by bonding overlapping rows of intersecting fibres.
