Title: Electric soldering iron
IPC: B23K3/03
Filed: 1968-10-25
Abstract: 1,208,645. Soldering. ERSA ERNST SACHS K.G. 25 Oct., 1968 [29 Feb., 1968], No. 50872/68. Addition to 1,130,064. Heading B3R. [Also in Divisions H3-H5] The soldering iron of the parent Specification is modified by providing a loop 13 in the end of the connecting wire 11 which passes through tubular former 7, locating the end 11a of the loop 13 in the former 7 so that the loop rests on the axial surfaces of a step formed by cutting away half of the periphery of one end of the former 7, and wrapping the winding 8 around the loop. The wire 11 has oppositely directed corrugations at the loop end which engage the inside of former 7 and retain the loop 13 in position. The heating wire 8 is wound around the loop 13 and hard soldered to it. The helical connecting end 16 is also hard soldered to the interwound heating wire and is housed in a silver solder jacket 17. The free end of the loop 13 projects beyond the end of the former and is filled with silver solder 18 which is embedded in a heat-proof coating 19.

Title: Wire lead forming apparatus and method
IPC: H01R43/027
Filed: 1966-11-15
Abstract: 1,100,696. Making electrical connections. AMP Inc. 15 Nov., 1966 [10 Dec., 1965], No. 51039/66. Heading B3A. Apparatus for forming wire leads comprises a guide member 18 defining a guide path, the guide member having an aperture 42, wire supply and positioning means 54 movable between a first position for tucking a wire into the aperture and a second position remote from the aperture, the means 54 including a tucking member 64, which in the first position tucks a bight of wire into the aperture, and a cutting device 52 at the aperture for cutting the wire at the bight. The means 54 comprises an arm 62 for the tucking member 64 and a wire feed tube 68 fixed on two yokes 56, 70 respectively, which yokes are mounted on a common pivot 60. In operation, the arm 62 is swung downwardly so that the end of a lead 90 is trapped in the aperture 42 and the tube 68 is engaged by a spring clip 92. A latch 82 is rotated counterclockwise and a spring 86 moves the arm 62 upwardly. Handle portions (8), (10) of the apparatus are pressed together, Fig. 1 (not shown), whereby a clip pusher 21 shears a clip 22 from a strip thereof and drives it forward over the guide member or mandrel 18. As the clip moves, it traps the wire between itself and the mandrel, stripping the insulation as it drags the wire along a groove 47. The tool is then positioned with a mandrel portion 40 in alignment with a terminal post A and the handle portions are urged towards the post so that the pusher 21 drives the clip and wire on to the post. The tool is then positioned against a further post with the wire suitably laid between the posts. The tube 68 is then released from the clip 92 and is secured to the arm 62 by the latch 82. The member 54 is then swung downward to form the wire into a bight in the aperture 42 and to sever it on the cutting device 52. The arm 62 and device 64 are withdrawn to allow a further clip to be pushed on to the second terminal post with the wire trapped therebetween.

Title: Apparatus for digitally controlling the magnitude of a machining gap in an edm process
IPC: B23H7/18
Filed: 1972-11-06
Abstract: 1359122 Automatic control of electrodischarge machining CINCINNATI MILACRON Inc 6 Nov 1972 [8 Nov 1971] 51102/72 Heading G3R [Also in Division B3] The gap size in electro-discharge machining apparatus is regulated by incremental movement of the machining tool in response to the detection of a predetermined consecutive number of either supply voltage pulses only or gap current pulses only. As shown, a machining gap 16 receives a pulsed supply from a circuit 10 comprising a D.C. source with series transistors switched by an oscillator, Fig. 2a, (not shown). A detection circuit 18, Fig. 3, (not shown), includes Zener diodes, operational amplifiers and transformercoupled multi-vibrators, and produces sharp pulses on two output lines corresponding respectively to current pulses and voltage pulses exceeding a threshold level. The pulses are fed to a gating and counting circuit 20 including respective voltage pulse and current pulse counters which are stepped by the occurrence of a voltage pulse alone or a current pulse alone respectively, and reset by a current pulse alone or a voltage pulse alone respectively. When one or other counter reaches a pre-set count, a control circuit 22 produces an output which causes a stepping motor 26 to advance or retract the tool 12 by a predetermined number of increments. The requirement for at least a minimum number of consecutive pulses of only one kind prevents gap resetting in response to momentary short or open circuits or delayed current flow. A connection from the circuit 22 to the output of the oscillator in the power supply 10 interrupts the supply when a retract demand signal is produced.

Title: Combination balance analyzer and vibration spectrum analyzer
IPC: H03K5/08
Filed: 1974-11-26
Abstract: 1506856 Measuring rotary unbalance electrically IRD MECHANALYSIS Inc 26 Nov 1974 [30 Nov 1973] 51111/74 Headings G1N and G1U The invention relates to apparatus for measuring the dynamic unbalance of a rotor 50 Fig. 7 using a displacement, velocity or acceleration pickup 54 at a bearing 52 to sense the unbalance vibrations and a pick-up 56 to produce a pulse train from a keyway 53 which is developed into sinusoidal, out-of-phase synchronous signals to be used as phase references for determining the angular position of the unbalance. The system includes active tracking filters whose centre frequency is controlled by ganged switches, and are used to remove unwanted frequency components from the vibration signals. The filters may be cut out for other tests. The pulse train from pick-up 56, fed to terminal 62 Fig. 2, is converted to a synchronous sine wave at 86 and a synchronous cosine wave at 94, both having the same constant amplitude independent of the pulse train frequency. The vibration signals from pick-up 54 are fed to terminal 60 or 61, and integrated if necessary to obtain a displacement signal, which is fed to multiplier 116 together with the reference sine signal at 86, and also fed to multiplier 120 together with the reference cosine signal at 94. The product outputs are fed through active filters 117, 121 to give D.C. signals from amplifiers 118, 122 representing the sine and cosine of the phase angle of the rotor unbalance. These modulate at 119, 223 a carrier frequency developed by generator 125 and the two modulated signals are added at 127 to produce the equivalent of the vibration signal from pick-up 54 but with no noise content. This signal is analyzed for amplitude and phase angle in a standard manner to determine the magnitude and angular position of the rotor dynamic unbalance. The reference sine and cosine signals at 86, 94 may be obtained from a digital sweep oscillator 136 instead of from the pulse train input at 62, whereby the frequency spectrum of the vibrations are analyzed, or from a power line voltage of known frequency at terminal 139, to check the frequency meter 11. A similar power line voltage at 191 enables the amplitude meter 10 and the phase meter 12 to be checked.
