Title: Device for the transmission of acoustic waves in water
Inventor: CHOLET JACQUES
IPC: B63B45/08
Filed: 1965-12-17
Abstract: 1,120,023. Seismic prospecting. INSTITUT FRANCAIS DU PETROLE DES CARBURANTS ET LUBRIFIANTS. 17 Dec., 1965 [18 Dec., 1964], No. 53673/65. Heading H4D. [Also in Division F3] Small explosive charges 7, for underwater seismic prospecting, are dispensed from a magazine (16), Figs. 2 and 3 (not shown), which is advanced in time with the oscillations of a rotary device (8, 12). In one position the charge passes through this device into a tube 3 which ends in an apertured metal sphere 1 wherein the charge is exploded. In another position the device is connected with a water pump 5 for flushing the charge down the tube 3. This tube is lined with an electrically insulating sleeve (41), Fig. 5 (not shown), and terminates at the sphere in a conductive crown (47) which is connected through leads (40) to a position in the boat 4. Crown (47) abuts an insulating crown (48) carried by the sphere. The cartridge consists of a charge (27), Fig. 4 (not shown), carried in an insulating sleeve (24). This sleeve has a belled-end (25) which seats on the insulating crown (48) so as substantially to seal the water passage (50) when the cartridge has reached the firing position. Sphere 1 is also electrically connected, e.g. through tube armouring, to a point in the boat. An electric detonator (28) in the charge (27) has loose leads (29, 30) extending from opposite ends so that in firing position one lead (29) contacts the water in tube 3 whilst the other lead (30) contacts the water in sphere 1. Tests of the resistance path between the crown (47) and the sphere determine whether the cartridge is properly seated in firing position, Fig. 7 (not shown). A firing pulse maybe transmitted through the same circuit, the tube armouring being an earth return, or this return may be made through the water and a submerged conductor. In modifications, Figs. 6, 6A, 6B (not shown), a renewable adaptor 54, Fig. 6, may connect the tube with the sphere. This adaptor has a conducting ring (60) connected to a ring (59) which contacts a complementary ring (55) in the tube end. In Fig. 6A, the ring (59) is connected directly to a conductor cable (63) outside the tube. In Fig. 6B, compressed air at slight excess pressure is supplied through passages (72, 76) after the cartridge is seated and a few seconds before firing so that the air flows upstream and downstream from the seating, in order to reduce the explosion shock on the parts and provide an insulating curtain of air bubbles over the surface of a metal insert seat ring (75) in the crown 48.

Abstract: 1375715 Dispensing measured quantities of fluent solids WOODMAN CO Inc 22 Nov 1971 [17 Feb 1971] 54062/71 Heading B8N Apparatus for dispensing measured quantities of fluent solid material comprises a removable unit mounted for rotation in a stationary unit. The removable unit comprises a hopper 12 having a bottom wall 41 provided with openings therein through which material in the hopper can flow into chambers 16, the chambers each having an adjustable, slanting bottom wall 51 and its radially outer side open, and the stationary unit comprises a substantially cylindrical, stationary wall 13 which closes the chamber openings until the latter register with a discharge tube 20. The removable unit also comprises a depending hollow hub 38 which has slots into which extend keys 35, 36 secured to a rotatable toothed wheel 33 driven intermittently by a motor (not shown) via a toothed belt C. A collar 56 which is slidable axially of the hub, within limits imposed by slots 58, by means of rotation of crank W, includes radial arms each of which supports a respective chamber bottom 51. A sweeper arm 120 secured to wheel 33 sweeps any material falling from the chambers to a discharge conduit 123. A baffle 70 secured to the wall 13 is positioned within the hopper 12 so as to prevent material entering a chamber which is being discharged. Removal of the baffle which may include a brush (78) (Fig. 4, not shown), and pivoting of a vibratory feed shoot 21 to an inoperative position allows an operator to remove the removable unit by grasping and lifting the handle 114. The bearing 39 is removed with the removable unit. The feed of material to the hopper via the vibratory feed shoot 21 is controlled by a sensing arm 86 secured to a shaft 87 carrying two cams for actuating respective microswitches (91, 92) (Figs. 5 and 6, not shown). If insufficient material is in the hopper the shoot 21 will be vibrated at a fast rate. If too much material is present in the hopper the vibration of the shoot will cease, and if sufficient material is present in the hopper the shoot will be vibrated at a slower rate.

Abstract: 1314357 Device for securing hot top tiles to chill moulds HILTI AG 18 Nov 1970 [15 Dec 1969] 54733/70 Heading B4C A device for securing hot top tiles to a wall of a chill mould comprises an explosively-actuated fastener-driving tool 1 having a support arm 10, an arm 16 pivotally connected to a clamp 15 and including a stop tongue 17, and means fo r  supporting a tile 21 prior to securing the tile to the chill mould wall 4b. The support means comprises a U-shaped member 3 having telescopic legs 3a, 7 and 3b, 8, the portions 7, 8 of the legs being biased by a spring 9, and an arm 20 pivotally mounted on a clamp 19 and biased by a torsion spring 22. In use a tile is supported on the legs of the U-shaped member and is retained by the arm 20. The arm 16 is then rested on the upper edge of the chill mould wall (4b) (Fig. 3, not shown). An operator stands on the arm 16 and pivots the support arm 10 about pivot 25 to bring the support means into engagement with the mould wall. Continued movement causes the legs and the arm 20 to release the tile which is held in place by the point of a nail 24 extending into the tile and by pressure of the tool 1 thereagainst. Depression of button 12 effects driving of the nail into the mould wall. The tool 1 cannot be fired unless pressed against the tile. The clamps 15, 19 are adjustable along the support arm 10.

Abstract: 1329317 Lubricating I.C. engines H LIST 25 Nov 1971 [ 7 Jan 1971] 54751/71 Heading F1B In an I. C. engine for oil testing, separate lubricant circuits are provided for the test oil and the ordinary lubricating oil, the oil-wetted engine interior being divided into separate oil zones sealed off from each other, each oil zone being associated with one of the two lubricating circuits. The main bearings 13, 14, Fig.2 are sealed from the crank-case 6 by seals 16. The annular space between bearing 13 and the adjacent seal 16 communicates with the housing for the gears driving the fuel pump 45 and the balance shaft 8 through ducts 17. The housing 11 is drained into chamber 7 through a closable port 39. A similar annular space is drained through duct 17a chambers 20 and 22 to chamber 7. The test oil flows through passage 24 to bearing 25 and piston 26. Oil from the valve gear drains through a hole 27, Fig. 1 into the cam-shaft housing and thence via hole 30 to chamber 6. The test oil drains into sump 31 and passes via an oil filter and cooler (not shown) to the circulating system. The oil in sump 37 returns to a separate circulating system. The two lubricant circuits arranged thus permit the test oil to be applied to those parts having heavy mechanical and thermal stresses. In another testing mode the test oil is allowed to impinge on the balancing shafts 8 by removing plate 9. In another embodiment joints 16 are omitted and a seal is arranged between the drive wheel.cover and the main bearings 13 so that the latter is included in the test oil circuit. In another embodiment only the pistons are included in the test oil circuit by arranging a spacer 50 Fig. 5 between the cylinder and crank-case, the piston being connected to a crosshead 51 by a rod 54 which passes through a stuffing-box 55. The test oil is delivered through a spray nozzle 57 and drained via duct 58. (For Figures see next page)
