Title: Improvements in or relating to mining machine cutter chains
IPC: E21C25/34
Filed: 1931-12-15
Abstract: 391,901. Mining-machine cutter chains. DOLPHIN, J. R. V. and HOY, A. Y., Bush House, Aldwych, London. Dec. 15, 1931, No. 34749. [Class 68 (i).] In a cutter chain in which each cutter-carrying block comprises two side plates which are joined by a bridge member and form between them a sprocket tooth throat, each block is formed with two pick sockets extending diagonally through the block so that the picks can project into the throat. Connector blocks, which may be rigid or may be articulated. about an axis perpendicular to the connecting rivets, are pivotally mounted between the side-plates of the cutter blocks. In the preferred form the block is formed from two identical drop forgings each comprising a side-plate 3 and half the bridge member 4, the member 4 being displaced longitudinally from the centre of the side-plate by a distance preferably equal to one half of the width of a pick socket. The members 4 are preferably formed approximately in the shape of hexagonal prisms and the sections are joined by a weld 2. An inclined pick socket 6 is machined in each of the members 4, preferably before the sections are welded together, the socket being continued to provide a recess 8 in the opposite side-plate 3. An aperture 9 is formed in each side-plate to facilitate removal of the picks. The picks are held in position by screws working in threaded bores 10 which may extend from one or both sides of the block. The side-plates are grooved externally at 15, 16 and are provided with upper strengthening ribs 17 and guide ribs 14. Rivet holes 11 are provided for connecting the cutter blocks with the connector blocks, the rivets being preferably provided with sleeves which extend between the side-plates and are secured against rotation by projections fitting into grooves 18. The top corners 13 of the sideplates are square cut to form shoulders against which abut corresponding shoulders on the connector blocks. Pick holders carrying short, e.g. reversible, picks may be used with the block in which case the sockets may be formed in the same transverse plane, the holders being made sufficiently short not to interfere with one another in the sprocket tooth throat. Specification 361,499 is referred to.

Title: Improvements in or relating to weighing apparatus
IPC: G01G13/00
Filed: 1960-10-13
Abstract: 889,896. Weighing apparatus. KONINKLIJKE INDUSTRIEELE MAATSCHAPPIJ VOORHEEN NOURY & VAN DER LANDE N.V. Oct. 13, 1960 [Nov. 20, 1959], No. 35131/60. Class 143. In an automatic feed weigher which delivers powdered or like material to a receptacle on a weigh beam, the final stage of the feed comprises the alternate operation, under the control of the weigh beam, of a dribble feed valve and a device for withdrawing excess material. As shown a screw feeder 12 delivers the material to a feed spout with two outlets respectively controlled by electrically operated slides comprising a bulk feed valve 13 and a dribble feed valve 14. The receptacle 1 is guided by leaf spring 2 and acts, through linkage 3, on a weigh beam 4 which operates switches 7 and 8 controlling the actuators 15, 16 of valves 13, 14 respectively to provide the conventional two-stage feed. When the weigh beam tilts a switch 9 actuates a valve 19 to admit pneumatic pressure to a tube 17 and expel material through an outlet pipe 18 until the beam rebalances. The thus constituted feed-off device operates in alternation with the dribble feed until balance is achieved. Discharge is by electrically controlled operation, which may be automatic, of the pivoted gate 10.

Filed: 1972-07-27
Abstract: 1397976 Live bait tackle T W HICKS 27 July 1972 [6 Aug 1971] 35206/72 Heading A1A A live bait holder comprises a flexible shell 11 which is shaped to receive the front part of a fish, e.g. a minnow, and has a rear opening 25 for the tail, a slot 26 to receive the dorsal fin, apertures for the lower pelvic fins 21 and a front opening 30 through which water passes to enable the fiish to breath. The slot 26 extends forwardly from the rear opening 25 and permits the fish to be inserted into the shell by compressing the top and bottom towards each other. Upon release, the shell reverts to its natural shape to confine the fish and the inner surfaces of the slot 26, which have corrugations 28, engage the dorsal fin. The inner rear surface of the shell 11 also has barbs to impale the scales of the fish if it moves rearwardly. Grooves 39 and 40 are formed along the length of the shell in the top and bottom and receive the shanks of fish hooks e.g. 41, which are attached thereto. A buoyancy means e.g. an air tank, may be provided on the rear outer wall to cause the bait to float on its side at an inclined altitude so that the consequent movement of the fish trying to return to a normal swimming position will attract the game fish. The shell is preferably made from transparent thermoplastics material and the forward part, which forms a hood for the fish's head, has opaque patches located to cover the fish's eyes.
