Title: Improvements in or relating to trimming machines suitable for use in the manufactureof shoes
IPC: A43D27/00
Filed: 1947-03-07
Abstract: 622,056. Sole-edge trimming-machines. BRITISH UNITED SHOE MACHINERY CO., Ltd. (United Shoe Machinery Corporation). March 7, 1947, No. 6454. [Class 17 (ii)] The chopping knives of a jointing machine for trimming the edges of a shoe sole in the waist between where the usual edge trimming operation ceases and the heel breast are normally stationary and retracted from their operating positions, until actuating means therefor for imparting one or more chopping strokes are operated by contact with the heel breast, on one side or the other, during the feed of the shoe in the machine. An illustrative form. of machine has an oscillatory trimming knife 12 with two curved cutting edges 13, 14 mounted and operated from a power driven shaft 18 as described in Specification 181,099, [Class 17 (i)], and two independently operated chopping units each comprising a knife 22 or 24 adjustably held in a carrier 23 or 25. The cutting edges of the knives 22, 24 are in the outer faces of the knives but extend in directions lying forwardly and rearwardly of the machine so that they are contacted by one or other of the edges 30, 31 respectively of the heel breast according to the direction of feed of the shoe in the machine. The carriers 23, 25 are pivoted on pins 34 carried by arms 35, 36, independently mounted on a central pin 37 fixed to the machine frame above the knife 12, and tension springs 39 normally lift the chopping blades and their carriers until the arms 35, 36 contact adjustable stop screws 40 on the machine frame, the knives 22,. 24 being swung thereby outwardly from one another. During feed of the shoe on one side it may advance for a short distance after the heel breast strikes the chopping knife at that side to move it until its carrier is arrested by a stop member 45 secured to the frame and which supports a guard and guide 50 which is intended to run in the shoe creaser. A plate 51, fixed to the forward end of a sleeve 10 by which the knife 12 is continuously oscillated, has extensions 54, 55 on opposite side to depress one or other of the carriers 23, 25 respectively by engagement with outwardly and rearwardly directed lugs 56, 57 respectively on the carriers, when one of the carriers is swung sideways about its pivot by the heel breast striking against it, to cause the chopping knife on that carrier to be thrust against and sever the shaving raised by the knife 12.

Title: Flash gun using flash bulbs
IPC: H05B41/32
Filed: 1969-02-07
Abstract: 1,203,536. Photographic flash-gun. PRONTOR-WERK ALFRED GAUTHIER G. m. b. H. Feb. 7, 1969 [March 14, 1968], No.6680/69. Heading G2A. A photographic flash-gun for use with expendable flash-bulbs has, in front of a bulb in the firing position a shutter 7', 8" which is electronically closed to prevent further illumination of the subject when the latter has been sufficiently illuminated for a correct photographic exposure as determined by a photo-resistor (R<SP>4</SP>"), Fig,2 (not shown). In use, the connector 3" of the flashgun is plugged into a camera and the shutter opened by depressing a button 22" to the position shown, this movement bringing an armature 41 carried by a shutter drive lever 13" into abutment with a holding electro-magnet 40. The lever 13" is held in positiion by springs 16", 17". When the camera is actuated, the flash-bulb (6") is ignited, thereby causing a current surge in the secondary coil of a transformer (45), the primary coil of which is in the flash-bulb ignition circuit. The current surge fires a thyristor (Ty), thereby energizing a tractor electromagnet 19", resulting in movement of an armature 20" to free the lever 13" from the springs 16", 17". However, the lever 13" remains in the position shown since the electromagnet 40" is energized as a result of the current surge, thereby retaining the armature 41 against the electromagnet 40. The current surge also energizes an electronic timing circuit (46) which functions via the photo-resistor (R<SP>4</SP>") and a changing capacitor (C<SP>5</SP>"). The circuit 46 trips in response to light on the photo-resistor (R<SP>4</SP>") and the electromagnet (40) is de-energized releasing the lever 13" to close the shutter. Means are provided to de-energize the electromagnet 40 after <SP>1</SP> 30  sec if not previously de-energized.

The cutter may comprise (as shown), a blade 44<SP>1</SP> combined with an eccentric material-crushing cam 58 and centring flanges 60 or (Fig. 1, not shown), a bit with a conical cutting surface. Broken-up particles enter the stem through apertures 48<SP>1</SP>. The cutter may be secured directly to the lower end of a Kelly 40. Alternatively one or more drill string sections 46 may be interposed between the Kelly and the cutter. Connections between adjacent drill string parts are by way of frustoconical screw threads. The Kelly is rotatably driven by a pneumatic or electric motor (Fig. 1, not shown), through chain or belt 24, wheel 22, rotatable bushing 20 and Kelly bushing 38. Co-operating slots and projections 34, 36 permit lifting of bushing 38 from bushing 20 when the drill string is raised to alter the number of sections 46. A generally U-shaped frame (Figs. 4-6, not shown), is engageable with the top of drive unit casing 16 and a flange 46b on a particular section 46 to lock the string angularly relative to the casing 16 and to prevent the string from falling back into pipe 10. The screw-threaded connection between the particular section 46 and the section immediately above same may then be undone to add or remove sections 46. Instead of gravity, a hydraulic or pneumatic ram (not shown), may provide the axial thrust at the cutter.

Filed: 1943-05-11
Abstract: 566,120. Casting concrete structures in situ. ROBERTSON, A. M. May 11, 1943, No. 7502. [Class 20 (ii)] Buildings of two or more storeys are constructed by first preparing a foundation, or foundation blocks, erecting columns thereon and supporting horizontal shuttering at or near the top thereof, concrete then being poured on the shuttering to form a reinforcedconcrete roof, after which the shuttering is lowered as a unit for the moulding of each of the reinforced-concrete floors in turn. The walls, doors, windows and partitions are finally erected between the floors and between the top floor and roof. The foundations a carry vertical columns b which may be lattice steel box columns for high buildings, but may be of hollow square reinforced concrete for two-storeyed buildings. Prefabricated horizontal shuttering c assembled in sections and slidable vertically on the columns by winches carried thereby, is secured to the top of the columns for the casting of the roof, stiffened channel sections being secured round the columns to key with the roof. The shuttering is then lowered as a unit to the top floor position, secured, and concrete similarly poured to form the top floor, this process being repeated until the ground floor is moulded, after which the shuttering is dismantled. The columns may be employed as conduits for various services, e.g. hot and cold water, gas, electricity, air ducts, heating pipes, telephone cables, bell wires, flues from coal fires and from centralheating plants, sewers and sewer vents, drainage pipes, overflows from w.c.'s &c., laundry shoots, coal lifts and vacuum service cleaning pipes. During construction, pipe-lines for delivering the concrete may be led through the columns. Some or all of the steel columns may be removed after the erection of the building, where strength considerations permit.
