Title: Improvements in or connected with machines for cutting coal and like minerals
IPC: E21C27/08
Filed: 1942-08-05
Abstract: 559,177. Coal &c. cutting machines ; ratchet gearing. LOGAN, W. A. - Aug. 5, 1942, Nos. 10908 and 15589. [Class 68 (i)] [Also in Group XXIV] A machine for cutting coal and like minerals into a series of slabs as it advances along the coal &c. face comprises' overcutting, under-cutting and shearing elements, all of the cutter chain type, and a severing cutter which is adapted at intervals to swing into the coal &c. in a substantially vertical plane at right angles to the coal &c. face, the severing cutter, while making this cut, remaining stationary as far as longitudinal advance is concerned. The machine comprises a base A carrying a motor and gear housing B, a shearing cutter C, an undercutter D, an overcutter F adjustably carried by a turret E, and a severing cutter H, the undercutting and shearing chains being driven by sprockets 2, 1, respectively, and the overcutting and severing chains being driven through the undercutting chain. The severing cutter H is carried by a gear box K slidable along its drive shaft M in guides L. In use, the machine is inserted into a recess in the coal &c. face and is then advanced along the face by a haulage cable wound, on a drum J. When a severing cut is to be made, the gear box K is held stationary by a clip engaging the haiilage cable and the cutter H is swung down into the coal ; the cutter H is then returned to the vertical, the clip is released from the haulage rope, and a divided nut is engaged with a screw 18 driven from the machine, whereby the gear box K and cutter H are advanced along the base E at high speed, after which the divided nut is released, and the clip re-engaged with the haulage cable, this being effected automatically by cam action. The swinging of the cutter H is effected through gearing 14, 11, Figs. 4 and 5, driving an eccentric 12 which oscillates two pawls 13 engaging opposed ratchet wheels 10 driving a. worm 9 meshing with a worm wheel 8 carrying the cutter ; one pawl is held out of action by a shroud, stops 16 on the worm wheel 8 acting at the end of each stroke to move the shroud and put the previously inoperative pawl in action, the return stroke then taking place. As the coal is cut away, it is propelled laterally on to a face conveyer N by means of curved guide P and scraper conveyer Q. In another form, the severing cutter is fixed against longitudinal movement relatively to the base A, advance of the machine being stopped while the severing cut is made. Specification 411,256 is referred to. The first Provisional Specification describes a form of apparatus in which the cutter H is replaced by a rotary cutter bar moved up and down as the machine advances so as to produce a sinuous cut.

Abstract: 1,013,645. Making electric components; soldering. RADIO CORPORATION OF AMERICA. March 19, 1963 [April 9, 1962], No. 10918/63. Headings B3A and B3R. [Also in Division H1] In a method of making an electrical module, connector wires 32 are arranged in parallel in a jig 30 to form a cage-like structure, circuit wafers 10 having metallized terminals 16 on their peripheries are stacked with interposed soluble spacers 40 in the structure, the wires 32 are soldered to the terminals 16 and the spacers 40 are dissolved out. The module is subsequently encapsulated and may form an amplifier, flip-flop circuit or a detector. The circuit wafers 10 consist of sheets 12 of insulating material, e.g. alumina, having metallized notches 14 forming the terminals 16. The wafers have printed circuits, e.g. resistors 18, 20 or connections 24 to components, e.g. transistors, attached to the sheets 12. A spacing block 38 is located next to the jig 30 and the stacked wafers 10 and spacers 40 are held under light pressure by hooked ends 32h of some of the wires 32. Each face of the stack is brushed with flux and soldered by dipping in a bath 42 filled with solder 44 until a meniscus is formed. The spacers 40, e.g. of alumina or zircon, in water glass or a resin or of aspirin, are dissolved out by agitation in alcohol or water.

Abstract: 538,332. Excavators. PRIESTMAN BROS., Ltd., and PIPER, C. W. June 28, 1940, No. 11030. [Class 68 (i)] [Also in Group XXX]  In a mechanical excavator comprising a boom that can be raised and lowered, and a scoop movable on the boom and actuated by a rope or chain, a stop or baffle depends from the boom at or near the end of the operative stroke of the scoop so that its lower edge is on or near the ground when the boom is in position for the scooping operation. The stop may comprise a plate with a straight lower edge, or a number of prongs. In Fig. 1, the scoop 14 moves on a boom 10 towards a stop 22 on the end of the boom ; the stop may resemble a grab jaw, and may be arranged near the pivot 12 if the filling stroke of the scoop is towards the pivot. In Fig. 3, the scoop 14 is carried by an arm 32 pivoted to the boom and controlled by ropes 34, 36, the scoop co-operating with a stop 22. For dealing with lumpy material, the stop 22 may be heartshaped as in Fig. 5, and smaller than the entrance to the scoop; laterallyinclined plates 42 are connected by angle members 44 to the boom, and prevent spreading of escaping material. In Fig. 7, the stop 22 is of U-section, is pivoted at 50 between sides of the boom, and is connected through links 58 to the hoisting rope 20, a stop 54 limiting its movement.

Filed: 1942-08-14
Abstract: 593,787. Bomb projectors. CAMPBELL, H. Aug. 14, 1942, No. 11412. [Class 92 (ii)] The hinged breech-block D of a bomb thrower is fitted with a self-centring sealing disc O adapted to engage with co-operating sealing means, such as a bevelled lip, encircling the breech end of the barrel bore. The sealing disc shown is secured by a screw Q to a member S having a curved annular bearing surface engaging with a corresponding surface in the breech-block. The member S houses the firing pin H and the latter carries at its rear end a knob G. The breech-block is swung about its pivot B by a handle A which is pivoted at X to the front face of the block about an axis parallel to the barrel Mb. When the breech is closed, the handle is swung upwards into locking engagement with a pillar F extending rearwardly from the breech ring R. When the handle is swung downwards to the unlocking position, a projection A<1>, formed on a cranked arm integral with the handle, engages behind the knob G and thereby locks the firing pin. The handle is locked in this lowered position by a spring-controlled lever E which engages in a notch of the handle, locking taking place only when the breech-block is swung downwards about pivot B. When the breech is closed, the lever E engages an inclined surface on pillar F and is thus disengaged from the notch. A spring-controlled lever e pivoted to a lug on the breech ring R is formed with a chamfered edge, whereby the lever is urged radially outwards by the bomb on loading and is then moved by its spring behind the bomb to hold the latter in position. The bomb thrower is provided with the range-controlling mechanism described in Specification 593,790.
