Title: Method and apparatus for forming piles in the earth
IPC: E02D15/04
Filed: 1961-05-18
Abstract: 954,842. Boring earth and concrete piling. RAYMOND INTERNATIONAL Inc. May 18, 1961 [Dec. 23, 1960], No. 18090/61. Headings E1F and E1H. Apparatus for forming piles includes an auger type drill 21 turned to drill a hole in the earth by an hydraulic motor 68 in a crown assembly 22, the drill having spiral flights and a hollow stem 69 (Figs. 13, 14) with a central tube 70 for conducting cementitious mixture or grout from a hopper 109 and pump 107 via conduit 90 and crown 22 to the drill tip and an outer tube 71 for conduiting drill mud or water from a conduit 84 out through a valve 140 to the lower end of the drill, the crown 22 being mounted in rails 24 for vertical movement on the mast 23 by means of a cable 92b forming part of the drill hoist assembly which comprises a cable drum 42 driven by an hydraulic motor 43 actuated from a pump 44 driven by an I.C. engine 55, the cavity formed during the withdrawal of the drill from the hole in the earth being filled with the cementitious mixture or grout delivered by the pump 107, the pressure thereof being sensed by an element 170 at the region of the lower end of the drill connected to a pressure comparator device 169 having an audible signal member 176, there being provided means for controlling the hoist to regulate the rate of drill withdrawal, means to control the pump 107 to regulate the rate of inflow of grout into the cavity, and means for adjusting one or both of such control means. A throttle lever 111 controls the speed of the engine 108 which drives the pump 107 through a clutch 112 actuated by a lever 115. The hoist motor is controlled by a lever 130. A depth-volume integrator indicator 134 is provided by means of which it is possible to correlate the movement of the drill 21 with the volume of the grout delivered by the pump 107, the interconnection between the drill and the indicator being via the hoist jack shaft 49 and an input 192 of the indicator, and that between the pump and the indicator being via a system 198, 201 to an input 191. The auger torque during drilling is recorded by a stylus on a moving strip 205. As shown in Fig. 13, during drilling the grout conduit 70 is closed by a valve plate 145 which is axially movable with respect to the drill stem 69 by virtue of a plurality of posts 146 passing through aligned passages 147 in the helix of the auger and communicating torque to the cutter head 148 secured to the plate 145. In Fig. 14 the auger is being hoisted, grout under pressure within tube 70 has opened valve 145 and is filling the cavity. A reinforcing bar or bars may be installed concurrently with the injection of the cementitious material, by employing an expendable cutter head, e.g. the auger of Fig. 19 has a cutting head 148a separable from the valve plate 145, a central reinforcing rod 153a which entends to any desired height up into the tube 70, and radially spaced reinforcing bars 153c located in guide tubes 153b extending along the sides of the stem 69.

Title: Improvements in or relating to fire detecting devices and apparatus embodying such devices
IPC: G08B17/06

Abstract: 653,864. Powdered and granular resistances ; temperature variable resistances ; wire and ribbon resistances ; resistance measurement ; cables. POOLE, R., TREADWELL, R. J., and WOOSNAM, M. S. July 6, 1948, No. 18140. [Classes 36 and 37] [Also in Group XXI] A fire-detecting element in the form of a flexible cable and constituting an electrical resistance comprises a flexible conductive shell or sheath, for example a flexible tube 10; Fig. 1, separated from a flexible conductive core 11 by a filling 12 consisting wholly or mainly of one or more metallic oxides whose resistance /temperature characteristic is negative, for example barium oxide or manganese oxide or nickel oxide or a mixture of two or more of these oxides. Spacers 13, Fig. 2, of suitable insulating material such as glass, ceramic or magnesium oxide may be positioned at intervals along the core 11 which may be a rod, wire, strip or helix made for example of copper or copper-nickel alloy. In the manufacturing method illustrated in Fig. 3 the powdered oxide filling 12 is introduced loosely into the outer tube 10 and metallic magnesium spacers 14 are threaded on and spaced along the inner conductive core 11. The assembly is then drawn through a die or passed between rollers 15 which reduce the diameter of the tube 10 to the finished size and compact the filling 12 and the spacers. The latter in compacted form indicated at 13 are then converted to magnesium oxide by heat treatment. In use, Fig. 4, if a fire occurs in the vicinity of the cable 16 the resistance of the oxide filling will rapidly fall and the current which then flows from the D.C. supply 18 will operate relay 19 and consequently the fire alarm or extinguishing apparatus 17. If a high resistance core 11 is used the position of the occurrence of a fire in relation to the length of the cable can be determined by measuring the resistance between the tube 10 and one end of the core 11.

The drive of the elevator and conveyer may be reversed. Bottom dump gates 90, are provided formed from pairs of doors 92, 94 upwardly hingeable together and powered by a double-acting cylinder and piston arrangement which also allows a spreader device 146 to be lowered when the doors are opened to the dumping position. A material detecting device 40 is mounted on the top rear of the bowl to indicate when the bowl is full.
