Title: Resistance heating control
IPC: B23K11/24
Filed: 1959-08-19
Abstract: 913,309. Automatic voltage-control systems for resistance welding. ROBOTRON CORPORATION. Aug. 19, 1959 [Aug. 21, 1958], No.28305/59. Class 38 (4). The voltage between the electrodes of a resistance welder is maintained equal to a reference voltage which is high enough to ensure fusion. In one embodiment, the voltage between the electrodes 105, 106 is measured at the peak of each half-cycle of electrode current by charging a capacitor 130 through a switching bridge-circuit 129 from the rectified output of a potential transformer 122 which is across the electrodes 105, 106. The output of a current transformer 145 is rectified and the resulting pulses are differentiated at 152, 153 to provide a waveform which passes through zero when the pulses are at a maximum. This waveform is squared by a bi-stable circuit 156 and again differentiated at 159, 160 to provide a pulse which is applied to the bridge circuit 129 to render it conducting during each current peak. The resultant voltage signal across capacitor 130 is via cathode follower 131 compared with a reference voltage tapped off a potential divider 111 any difference being amplified by a direct coupled amplifier 167, 168, 169, 171 and used to phase-modulate a train of firing pulses generated at 108 and applied to ignitrons 100 which are supplying the welding current. In another embodiment, Fig. 3 (not shown), the average electrode voltage is measured, the peak current sampling being omitted, and the amplified difference between this voltage and the reference voltage controls a phase-shift circuit to control the firing of the ignitrons.

Abstract: 959,731. Machine tool details &c. E. M. TOROSSIAN. July 26, 1962 [April 3, 1962], No. 28818/62. Addition to 955,889. Heading B3B. [Also in Division Fl] The pressure device of the parent Specification for moving the jaw of a vice is modified by arranging for the head 2 of the pneumatic cylinder 1 to be the fixed member of the vice while the hydraulic cylinder 3 enclosing the head serves as the actuating member when pressurized by movement of a pneumaticallyoperated plunger 6 which slides through a movable piston 4 into a bore 5 in the head and thereby compresses the fluid in the hydraulic cylinder 3. The device, which can be fixed on the table of a machine tool at 9, is provided with adjustable springs 12 for restoring the cylinder 3 upon release of the clamping pressure. The device is controlled by a valve which first admits air through the port 13 to cause the piston 4 to force hydraulic fluid into the cylinder 3 and so effect the initial clamping movement of the latter and then admits air through the port 14 while connecting the port 13 with atmosphere so that the piston 7 causes the plunger 6 to isolate and compress the hydraulic fluid in the cylinder to produce the final clamping movement.

Abstract: 364,029. Animal traps. BARNES, A., Market Place, Ulverston, Lancashire. Sept. 26, 1930, No. 28877. [Class 5 (i).] A snare comprises a noose and a two-armed releasable spring device, one end of the noose, which is formed by passing the said end through an eyelet or loop on the other end, being passed through an eyelet at the extremity of the upper arm of the spring device and being made fast to the lower arm. The lower arm 1 of a spring 7 is formed with a kink 6, a loop 2 through which a peg may be driven into the ground, and a vertical portion ending in a catch 5. The upper arm 8 is bent at 13 to grip an eyelet 14 and at 9 to form a hook for engagement with the catch 5. One end of a flex 12, formed of strands of brass wire, passes through an eyelet on the other end to form a running noose and then passes through the eyelet 14 and is attached to the kink 6 on the lower arm. In a modification, Fig. 3, the upper arm 8 is formed with a vertical portion 15 so that the greater part of the arm is near the ground and consequently less visible. Specification 243,872, [Class 5 (i), Farmyard &c. appliances], is referred to.

[Also in Division G4] In an accumulator (see Division G4) a shift register 29 and associated gates employ apertured magnetic cores as shown. An OR gate is as described in Specification 1,018,614 and comprises cores A x , A y , B q , linked by winding 40. An AND gate is as described in Specification 1,018,615 and comprises cores B p , Bq, A y , B n  linked by winding 41. An EXCLUSIVE OR gate is as described in Specification 1,018,617, and comprises cores B q , B n , A 1  linked by winding 28. The shift register comprises two sets A 1  ... A n , B 1  ... B n  of cores which are interconnected as shown, each core being capable of being in a " 0 " state, a " 1 " state, or a " primed 1 " state. If a core A 1  (Fig. 4, not shown) is in the " primed 1 " state, a clearing pulse through winding 10A induces a current in the output winding 9A 1  which is effective to set the core B 1  to the " 1 " state. This core may now be primed by a pulse on winding 8B and subsequently cleared by a pulse on winding 10B. Backward transfer of information in the shift register is prevented by threading each clearing winding through all the smaller apertures in the other set of cores (Fig. 5, not shown).

Abstract: 629,460. Aircraft fuel tanks. ANDERSON, J. R. June 4, 1946, No. 29542/47. Divided out of 612,881. [Class 4] An aircraft of the kind adapted to take off and land in a vertical attitude, in the 'manner of a helicopter, such as described in Specification 568,548, has its fuel tanks so arranged that a sufficient quantity of fuel is always available for landing, a part of the fuel being carried in a tank with its outlet so positioned that, with the aircraft in a substantially horizontal attitude some of the fuel is below the outlet level and cannot be withdrawn, the outlet being at substantially the lowest point of the tank when the aircraft assumes a nose-up attitude. In the form shown the fuel pipe 54 is connected at 55 to a tank 53 at the rear of the fuselage, the point 55 being in the top of the tank and near the rear thereof. To prevent fuel from passing into the pipe 54 when the aircraft is flying at a considerable angle to the horizontal, but not in the vertical landing attitude, a valve 58 may be fitted at the outlet. The valve is operated by a weight 62 on a pivoted arm 61, the latter of which passes a dead-centre position as the aircraft assumes a vertical attitude. The attitude at which the valve opens is controlled by an adjusting screw 65, and a spring detent 66 retains the valve in the closed or open position. The valve may be operated by a solenoid which is energized by the closing of a mercury switch when the aircraft assumes a predetermined attitude, or such a switch may be used to control a pump which draws from a reserve supply. Additional fuel tanks 51, 52 may be mounted in the wings and fuselage respectively, the points of connection 56 with the fuel supply pipe 54 being located as the bases of the tanks.
