Title: Shank lasting machine
IPC: A43D21/12
Filed: 1962-12-21
Abstract: 963,514. Shank lasting machines. EUGEN G. HENKEL MASCHINENFABRIK. Dec. 21, 1962 [Jan. 23, 1962; Sept. 11, 1962], No. 48465/62. Heading A3B. A shank lasting machine comprises a plurality of wiper fingers 35, vertically displaceable from rest to a working position and operatively associated with a plurality of vertically displaceable exploring pins 19 adapted to contact the bottom 76 of the last 75, so that the wiper fingers associated with the individual pines are vertically displaceable in accordance with the vertical displacement of the exploring pins to be exactly adjusted in the lasting position. In the operation of the machines after the last carrying the wiper 77 is in position and the heel band 53 is closed, oil is introduced into a cylinder 7 to cause a housing 4 carrying the exploring system 2 to move downwards against tension springs 17, the lateral arms 20 of the exploring member pushing the wiper fingers 34 downward against the action of springs 39, until the exploring fingers 19 contact the centre of the insole 76 mounted on the last. The exploring members are then pushed upwardly in the housing against the action of springs 22, and thus the fingers are adjusted in accordance with the slope of the shank. Shank formers 50 are positioned along the line of slope of the shank by a rearward extension 74 of the front wiper finger pressing a roller 70 connected via an arm 69 with the shaft 65 on which the suport head 78 of the former is disposed. Blade type wipers (not shown) close to last the heel, and oil is admitted to hydraulic cylinders 59, forcing the formers by means of slides 55 against the last 75. The formers are pivoted to enable them to be adapted to the contours of the last. Simultaneously oil is admitted to cylinder 45 so that the packs of wiper fingers are compressed by pressure plates and are locked in their adjusted position. The entire supporting part 27 is then advanced against the last 75, so the fingers 34 last and adhesively secure the margin of the shank over the insole, the exploring system 2 being at the same time retracted to its starting position due to the movement of the wipers opening a valve to release the oil pressure in cylinder 7. The last support is moved upwardly to press the blade wipers and wiper fingers more firmly against the last. Specification 963,513 is referred to.

Title: Method for arc-welding with a non-consumable rod electrode
IPC: B23K9/028
Filed: 1964-11-30
Abstract: 1,088,425. Welding by fusion. APPARATEN-EN KETELFABRIEK DEN HAAG N.V. Nov. 30, 1964 [Dec. 13, 1963], No. 48562/64. Heading B3R. In arc welding two contacting members at the zone of contact, one side of the welding supply is connected to one member, an arc is drawn from the other member to a non- consumable rod electrode connected to the other side of the welding supply, and the electrode is moved so that the end of the arc moves along the other member at a constant spacing from the zone of contact. In this way tubes 2 may be internally welded to a tube plate 1 and if desired an L-sectioned filler ring 7 may be interposed between the tube and the plate. The tube is engaged by a contact 3 and a tungsten electrode 4 connected to the negative pole of the supply 6 is moved at a constant distance from the ring 7. A weld is formed partly by the heat of the arc which is drawn to the side of a bore 10 in the tube plate 1 and partly due to passage of welding current through the plate 1, ring 7 and tube 2 in series. It is stated that the Lorentz force set up by the current pulls the weld metal towards the electrode (i.e. the negative pole) and so the effect of gravity, is counteracted and a weld shaped as shown at A<SP>1</SP> and not as shown at B<SP>1</SP> is obtained. The force on the weld metal may be adjusted in size and direction by connecting an auxiliary supply 5 across the tube 2 and the plate 1 to pass an auxiliary current through the weld to set up the desired force on the weld in the desired direction. In a modification a strip or tube is similarly externally welded to a plate. Gas shielded arc welding with shielding gas also supplied to the inside of the tube may be used.

A fastening device for securing a container to a vehicle comprises a housing having an upper surface, which, in use, consists of a part of a surface of the frame of the vehicle and a head element displaceable through an opening in the upper surface which opening corresponds in plan view to the shape of the element which is angularly displaceable, the head element either projects from the upper surface or is retracted below the surface through the opening upon angular displacement. The housing comprises an upper member 10, a parallel member 14 extending between spaced side walls 12, 13 secured to an upright wall, a stem 15 passing between the side walls and through apertures in the members 10 and 14 and a rod 16 passing through the stem with the head 17 at one end and a handle 18 at the other end. The opening in the member 10 has a similar shape to that of the head 17 in two directions at right angles. In an inoperative position, the head lies within the housing; to extend the head through a part of the opening to an operative position the stem 15 is moved axially and then rotated through 90‹ to free the handle from the lower ends of the walls so that a piece 23 of the stem having the same peripheral shape as the head can be raised and then rotated through 90‹ to align with the head and then lowered to seat the piece 23 on the upper ends of the walls. The handle is turned through a night angle and the head and piece 23 are inserted through a similarly shaped aperture in the container with the head extending above and by rotating the handle through 90‹ to the head is turned to the container retaining position. In a modification, (Fig. 6, not shown) the handle is pivotable for stowing within the housing and is releasable by axially pulling against spring pressure. The rod has, at right angles to the head, a spaced block of similar shape and a rotatable sleeve extends between the head and the block.

Title: Spark generating systems for internal combustion engines
IPC: F02P7/03
Filed: 1970-10-20
Abstract: 1371042 Ignition systems PLESSEY CO Ltd 30 Sept 1971 [20 Oct 1970 (2)] 49695/70 Heading F1B An ignition system for an internal-combustion engine comprises a transformer 5, 6, 7 or 8 suitable for mounting on a spark plug of the engine and for providing an E.H.T. voltage for spark production purposes and a storage capacitor arranged to be charged to an HT voltage and discharged through a winding of the transformer consequent upon the operation of switch means to supply spark intensifying energy. The power supply comprises an oscillator including a transistor 26 and a transformer having windings 27, 28, 29. The winding 29 is coupled to feed the storage capacitor 9 through a rectifier 30. Control pulses are supplied to the terminals 22, 23, 24 and 25 of the silicon controlled rectifiers 14, 15, 16 and 17. When a control signal is applied to the terminal 22 the silicon controlled rectifier 14 is switched into its conductive condition and a current pulse passes from the storage capacitor 9 through the primary winding 5a of the autotransformer 5 to charge the relatively small capacitor 10. An induced secondary voltage results which causes breakdown of the spark gap of the sparking plug 1. A large spark maintenance current is passed through the secondary winding from the storage capacitor 9 to fully develop the spark in the plug 1. The diode 18 permits discharge of the capacitors 10 through the winding 5 producing a current which helps to intensify the spark. The system may be associated with a conventional mechanical contact breaker/distributor arrangement or with an electronic distributor as described in Specification 1366859. Transformers which are mounted on top of the plugs may be wound on ferrite material.

Abstract: 1463019 Automatic brightness control G D SEARLE & CO 19 Nov 1974 [23 Nov 1973] 49988/74 Heading G3R The brightness of a CRT display in a scintillation camera is controlled by adjusting the intensity of the CRT beam in response to a comparison of an electrical signal representing the sensed light output from a raster generated over a portion of the tube and a reference signal.  As shown in Fig. 1, a tube 14 is driven in response to a scintillation detector 10 or, when a contact 44 is closed, a calibrating generator arrangement 38, 40, 42. The generator produces a scanning raster, Fig. 2, the size and position of which are determined by X and Y deflection circuits 40, 42, and the raster lines are broken up into series of dots by a blanking circuit 38. The brightness of the raster area is detected by a photodiode 28 which provides a signal through integrating amplifiers 30, 32 to each of a pair of comparators 54, 56 which also receive reference voltages from a switch and potentiometer network connected to a reference supply 48. The comparators 54, 56 effectively define a window, and if the measured brightness signal lies outside the window one or other of a pair of light emitting diodes 58, 60 is illuminated. A resistor 16, controlling the CRT beam intensity, is adjusted either manually or by an automatic electrical response, until the tube brightness is returned to a value within the desired range. In a modification, Fig. 3 (not shown), the effects of external light background and electrical noise are minimized by using a sampling technique together with A.C. amplifier coupling and integrators between the photodiode 28 and the comparators 54, 56.

Abstract: 1,089,277. Magnetic storage devices. INTERNATIONAL BUSINESS MACHINES CORPORATION. Jan. 20, 1966 [Dec. 12, 1964], No. 50679/64. Heading HIT. [Also in Division H3] In a transfluxor type magnetic information storage device suitable for use in a word organized memory matrix the core is blocked to produce a " 0 " state by the aiding effect at control hole C (Fig. 4) of a positive pulse (R+, Fig. 5, not shown) from write-read driver 28 and a long positive pulse from write driver 32. The effect of the positive pulse at read hole R is cancelled by a coincident pulse from bias driver 31. A " 1 " is written by a negative write pulse from 32 aided by a negative (R - ) pulse from word driver 28. These together tend to reverse the magnetization of the whole core but the R - pulse in the control hole R (there being no bias pulse to neutralize it) secures a circular flux around R. A modification comprises a two-core per bit device having two cores (34) (35) (Fig. 6, not shown) which are similarly wound except that the bias driver winding (40) passes through both control holes C as well as through both read holes R. In this arrangement when a " 0 " is stored a first core is blocked and the second core is unblocked, read out giving a negative pulse followed by a positive pulse. For a " 1 " the first core is unblocked and the second core blocked so that in the read-out the positive pulse occurs first. Instead of a common read-out winding linking the control hole the bias winding may be used. Constant voltage, instead of constant current, sources may be used.
