Title: Improvements in dough moulding machines
IPC: A21C9/08
Filed: 1921-08-18
Abstract: 186,779. Thomson, Ltd., D., and Tait, A. Aug. 18, 1921. Rolling-machines; feeding.-In a dough-moulding machine in which the dough is subjected to cross-rolling operations whilst travelling along a straight path, the dough after preliminary rolling passes over a roller and engages at one side a fence or directing-device whereby the dough is turned through a right-angle before passing to the cross-rolling device. Dough is fed into a hopper A on to a band c which carries it beneath a sheeting-roll B, curler h, and priming-board E, the rolled dough passing over a roller G on to a second band H which carries it beneath rollers J, K, a pair of curlers, and a final moulding-band S. The diverting-device F has one side F<1> extending above the roll G to retard one end of the dough roll and cause it to be deposited lengthwise upon the band H. The curlers h are supported by weighted rocking levers D so as to rise above the dough after curling the front edge. In a modification, the curlers are mounted between a pair of discs.

Title: Improvements in or relating to spring-powered starters for internal combustion engines
IPC: F02N5/02
Filed: 1950-09-08
Abstract: 704,074. Turning-gear. KLOCKNERHUMBOLDT-DEUTZ AKT.-GES. Sept. 8, 1950 [Sept. 17, 1949], No. 22229/50. Class 7(5) In a spring-powered starter that is drivingly coupled to the engine crankshaft 2, Fig. 1, so that the latter is turned to a limited extent by hand or separate power source before the starter operates by spring power to turn the crankshaft for starting purposes, the coupling of the starter with the crankshaft is so arranged that the -limited turning of the crankshaft ceases before the loading of the spring 6 commences. Between the engine frame 1, and fly-wheel 3 is arranged the spring casing 15 the inner end 7, Fig. 2, of which engages one member 8 of a unidirectional pawl and ratchet coupling whilst the outer end engages the casing, the periphery of the casing 15 embodying teeth 16 and the casing itself being rotatable on the member 8. Upon operating a hand lever 18 two spring-loaded pawls 23, 24 rotate the casing 15 through the teeth 16 in the engine starting direction so that the spring 6 slowly turns the engine through the unidirectional coupling until a spring- loaded pawl 26 on the fly wheel abuts a pin 27 on the frame 1 after traversing a given angle thereby preventing further rotation of the engine. Continued operation of the handle 18 tensions the spring 6 after which the pawl 26 is moved out of engagement with the pin 27 by a cam 30 on the casing 15 and the engine is then free to rotate as a result of the effort applied by the spring 6. The position of the cam 30 may be varied to effect differing degrees of spring tension. Centrifugal force acts to hold the pawl 26 in the inoperative position, a stop being provided to prevent the pawl swinging too far outwardly. The hand lever may be replaced by an electric motor, for example, the casing pawls being mounted on two eccentrics displaced relatively to each other whilst a reduction gear may be interposed between the electric motor and the tensioning shaft. The angle moved through by the crank before the spring is fully tensioned depends upon the number of cylinders in the engine.

Abstract: 598,206. Automatic control systems for supply circuits; rectifying. STANDARD TELEPHONES & CABLES, Ltd. Aug. 31, 1945, No. 22477. Convention date, Sept. 30, 1944. [Classes 38 (ii) and 38 (iv)] Voltage regulation of an A.C. to D.C. conversion system is achieved by a saturable reactor, the saturating winding of which is supplied with direct current controlled, e.g. by a carbon-pile regulator, so that changes in the D.C. output voltage result in magnified changes in current in the saturation windings. As shown, the A.C. supply 29 is connected to primary winding 10 of transformer 3, the secondary 2 of which is in series with full-wave rectifier 1 and the A.C. winding of saturable reactor 4. The rectifier output is smoothed by choke 6 and condenser 7 in parallel with bleeder resistance 9. Saturating winding 11 is in series with carbon-pile 16 and a D.C. source derived, for example, from a full-wave rectifier 13 energized from secondary 14 of transformer 15. Pressure is applied to the carbon-pile by bell-crank lever 17, subjected to the opposing moments of tension spring 19 and plunger and solenoid 20, 21. The solenoid 21 is energized from the potentiometer 22 connected across the D.C. output. Hunting is reduced by the action of transformer 24, in series with coil 21, the secondary 25 of. which reflects sudden changes of load voltage, across winding 11, which tend to neutralize the inductive effects of coil 11. In a modification, the saturable reactor is connected in series with the primary of transformer 3.

Abstract: 762,868. Transistor pulse delaying; generating single-stable and bi-stable state circuits. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. Nov. 15, 1954 [Aug. 15, 1953], No. 22560/53. Class 40(6) A point contact transistor 20 is arranged to operate with nearly equal emitter and collector currents to feed a load 26, the circuit being triggered by a potential applied to the emitter, the latter being derived from a capacitor 34 charged through a, resistor 35 and discharged through the transistor, A time delay circuit may be formed by triggering to the off state by a pulse applied to the base, the resistorcapacitor combination determining the delay before the circuit is restored to the stable on condition. In the steady state transistor 20 conducts current passing through diode 32 and the emitter-collector path of transistor 20 to the load 26, current also passing through resistor 28 from battery 29. A positive triggering pulse applied at terminal 24 to diode 25 causes the transistor to pass to the non-conducting state, the collector potential and hence that of point X falling to a negative value. The capacitor 34 is charged over resistor 35 until the point X is carried positive with respect to the base, whereupon the transistor conducts, the capacitor 34 discharging rapidly through diode 37 and the emitter-collector path of the transistor. During the off period the base is maintained at the potential of battery 31 due to diode 30 conducting. The resistor 38 ensures adequate current through the transistor when in the on condition. A small resistance may be included in the base lead to improve the resetting sensitivity. A discha,rging transistor may be arranged across the load in the manner described in Specification 762,867. The load may be capacitive and the resistor 38 may be large so that the circuit is unstable in the on condition and then oscillates continuously. A bi-stable state circuit is described, Fig. 2 (not shown) which dispenses with the elements 34...38 and is triggered on by a negative pulse over a diode connected to the base or by a positive pulse applied to the emitter, and reset by a positive pulse applied to terminal 24.
