Title: Improvements in soldering apparatus or the like
IPC: B23K3/06
Filed: 1935-11-14
Abstract: 463,141. Soldering irons. WOOD, C. E., and HARPER, T. Nov. 14, 1935, No. 31529. [Class 83 (iv)] A solder-feeding device for soldering-irons comprises one operating-means whereby the solder may be fed forward or moved laterally towards the bit, wherein the lateral movement may be effected without first feeding forward the solder. The shank 11 of the bit 12 may be secured through insulation to a pistol grip 10 carrying the cable 14 for an electric heater. To the grip is pivoted at 15 a pair of arms 16 retracted by a spring 24 against an adjustable stop 25. A block 17 fixed to the upper ends of the arms and to which is secured a curved solder guide tube 21, cooperates with a pair of feed rolls 19, 20 with chamfered and milled edges. The roll 19, which carries an operating knob 23, is mounted in one of the arms and is held in contact with the other roll 20 by a spring 29. The roll 20 is mounted on the shaft 27 of the roll 19 and is pinned at 28 to the roll 19. Short ends of solder are retained in the guide tube by a spring 31. The extremity of the bit has a longitudinal slot, a hole, or grooves in both surfaces meeting at the tip to conduct molten solder to the under surface of the bit. In a modification the feed mechanism serves as an attachment to an existing iron, being mounted in a spring-retracted block pivoted to a member secured to the shank of the bit. The solder for these forms of apparatus may be'in the form of solid or flux cored sticks. In a further modification for heavier gauge solder such as D-section strip, a spring retracted block 41 is pivoted at 40 to a clamp 38 secured to the shank 11. A feed roll 42 with operating knob 23 is mounted in a U-shaped bracket 43 pivoted at 44 to the block 41 and held down by a spring 45. The roll 42 cooperates with an idle roll 46 carried by the block 41. The guide is adjustable and consists of a V-shaped strip 47 surmounted by spring-pressed plate 48. The solder is fed against a projection 50 on the bit and molten solder flows down a channel 52 in the bit. In a further form a spring-retracted block such as 41 provided with a straight guide tube is connected to the top of a pistol grip by a pair of parallel links, a restoring spring being provided. The lateral movement of the solder may also be effected by mounting the feed mechanism on inclined slides. Specification 463,162 is referred to.

Title: Radar target detection installation
IPC: G01S7/292
Filed: 1963-08-14
Abstract: 1,058,823. Pulse radar. TELEFUNKEN PATENTVERWERTUNGS G.m.b.H. Aug. 14, 1963 [Aug. 22, 1962], No. 32109/63. Heading H4D. Relates to a pulse radar incorporating a beam scanning in azimuth, a train of echoes being received from a target according to the pulse repetition frequency, beam width and beam rotational speed, a range gate (2) opening for a period equal to the transmitted pulse duration, and the receiver video output (1) being digitized into negative O pulses corresponding to signal amplitude below a threshold level and positive L pulses for other signal amplitudes. A binary counter (5) is stepped on by L pulses and cleared by O pulses such that when S successive L pulses ensue a logic circuit (7) issues a signal by which target azimuth is determined. If the number of target echo pulses expected per beam width is N, S is made some N/2. The L and O pulses are separated by diodes (3, 4) and when S of successive L pulses ensue a signal is sent to an AND gate (8) which issues a pulse on the arrival thereat of the next O pulse, the counter contents then passing to a set of conductors (11), thereby representing the angular width of the target. The output from the AND gate (8) also interrogates a counter representing instantaneous aerial azimuth relative to north for target bearing determination in conjunction with the measured target angular width. A delay line may be inserted in the zero-setting input to the counter to ensure that the counter can issue its contents before being re-set. Like devices may be provided for different range gates or it can be arranged by storage that one device only is necessary.

Abstract: 1,033,701. Combined dampers and relief valves. THERMO-TECHNICAL DEVELOPMENT Ltd. Aug. 27, 1962 [Sept. 7, 1961], No. 32121/61. Headings F4B and F4W. A flue damper which is normally operated manually or automatically is made of light weight construction and opens automatically by the springing of a toggle mechanism when a predetermined excess gas pressure is reached in the flue inlet. As shown, a lightweight ball valve 2 seats in an apertured plate 1a and is pivoted to parallel links 3, 4 of which the link 4 forms one arm of a bellcrank of which the other arm is connected by a spring 7 to a further bell-crank 6 mounted on the hinge pin 5 of the first bellcrank. A nut 8 on a lead screw 9 driven by an electric motor is mounted in a slot in one arm of the bell-crank 6. Normally, the valve 2 is operated by the motor 10 through the two bell-cranks, but if the flue inlet pressure rises unduly when the valve is closed, the spring 7 moves over the dead centre position and the valve opens. It must then be re-set manually. In a modified toggle arrangement, the bellcranks are replaced by straight lever arms, the ends of which are connected to a link surrounded by a toggle spring.

Filed: 1959-09-22
Abstract: 953,532. Control of A.C. motors; multiwinding motors. LAURENCE, SCOTT & ELECTROMOTORS Ltd., and K. K. SCHWARZ. Dec. 12, 1960 [Sept. 22, 1959], No. 32302/59. Headings H2A and H2J. A polyphase electric motor 1, having two independent primary windings 5, 7 with no mutual inductance between them, is supplied from either of two sources. As shown, each source is an alternator, one 11 being driven by an A.C. motor 15 fed from mains 17 and speed controlled by an induction regulator 19, while the other 29 has a D.C. motor 33, with a variable field 37, on a battery supply 35. The primary windings 5, 7 are permanently connected to their respective alternators, both of which may be running continuously; power will be provided by the alternator whose field switch 25 or 43 is closed. Since there is no mutual inductance between windings 5 and 7 no current will flow in the circuit of the idle alternator. Mutual inductance is prevented by making the number of poles of one winding an even integer of those of the second winding; the poles of the two alternators 11, 29 are in like ratio so that no speed change occurs upon transfer. In an alternative arrangement, the motor winding 5 is supplied directly from the mains 17 and the remaining alternator 29 has compound field windings. One winding is permanently connected to rectifiers supplied from a current transformer in the output of the alternator while the other is automatically energized from the battery supply 35 upon low mains voltage and/or overcurrent in the winding 5, in which case the mains 17 are disconnected. It is stated that the alternator 29 may be driven by a prime mover instead of the motor 33, started automatically, and that the motor 1 may be wound for, and be provided with, more than two alternative supplies. Specification 738,524 is referred to.

Abstract: 637,033. Transformers. REYROLLE & CO., Ltd., A., and SCARROTT, G. G. Dec. 9,1947, No. 32458. [Class 38 (ii)] [Also in Group XXXVII] An electric transformer arrangement comprises a core having two primary windings energized respectively by two alternating currents, a secondary winding and, inductively coupled with the first primary winding, another winding having a half-wave rectifier connected thereacross so that a unidirectional flux is induced in the core according to the magnitude of the first primary alternating current and which is used to control the inductive linking between the second primary and secondary windings. A system or apparatus B is protected by two current transformers A, A<1> connected so that circulating current flows through the restraining winding G by way of the pilot circuit C. A unidirectional flux is induced in the core, representative of the circulating current by reason of the half-wave rectifier H<1> and which divides itself equally between the two magnetic circuits. The other primary winding J, J<1>, arranged to be non- inductively coupled with the winding G, is energized from two normally equipotential points in the circuit C, the excitation of the restraining winding G governing the inductive coupling between this winding and the secondary winding K, K<1> and therefore the operation of a relay E in the coil circuit of circuit breakers D. Thus in a biassed protective system the biassing effect is dependent upon the relative magnitudes of the two alternating currents only and not upon the phase displacement between them. In other embodiments, the core may comprise two simple loops, each winding then comprising two serially-connected parts, or the windings J, Jl, K, K<1> may be combined to form an autotransformer. An adjustable impedance may be connected either in series or parallel with the rectifier to govern the amount of ripple in, and the time taken to establish the unidirectional flux in the core. Specifications 193,434 and 216,254, [both in Class 38 (v)], are referred to.
