Filed: 1963-12-11
Abstract: 1028019 Animal drenches N J PHILLIPS PTY Ltd 11 Dec 1963 [11 Dec 1962] 48863/63 Headings F1A A1A3 A1B8B A1C1 A3F1B1 A4H A4L and A4S5A An animal drenching device comprises a hand pump 1, 2, a projectable oesophageal tube 34, inlet and outlet ports 11, 13 in the pump and a valve 16 having ports 23, 24 arranged to register with the inlet and outlet ports so that, when the oesophageal tube is retracted, only the inlet port is open, and when the oesophageal tube is projected, only the outlet port is open. The pump comprises a cylinder 1 in which a plunger 2 is reciprocable by a spring-retracted lever 5. The inlet port 11 is connected to a liquid reservoir through a union 12 and a flexible pipe (not shown). The outlet port 13 is connected to a radial delivery pipe 14 which extends as far as channel 27 in a quadrant plate 25 which forms the actuating member of the valve 16. The oesophageal tube of flexible transparent plastic is connected to the delivery tube 14 and extends along the channel 27 and through a guide tube 28 secured to the quadrant plate. The valve 16, comprising a disc which has a facing 17 which may be of natural or synthetic resin, is rotatable within the cylinder by rotating the quadrant plate relative to the cylinder and the delivery pipe. As the quadrant plate is moved to open the outlet port 13, the guide tube 28 is withdrawn from the oesophageal tube. Liquid drawn into the cylinder 11 may then be discharged through the oesophageal tube on depressing the plunger. The device may be used with liquids containing an active agent in suspension, the plunger being reciprocated in the cylinder with the inlet port open to agitate the liquid by alternately drawing it from and returning it to the reservoir. A catch is provided to secure the oesophageal tube in retracted position.

Abstract: 1495690 Removing H 2 S TEXACO DEVLOPMENT CORP 29 Nov 1975 49130/75 Heading C1A H 2 S is preferentially removed from a gas mixture containing H 2 S and CO 2  by (a) contacting the gas with an aqueous solution containing HCO<SP>-</SP> 3  in sufficient concentration to prevent solution of CO 2  and (b) oxidizing the dissolved H 2 S to sulphur by reaction with dissolved O 2  in aqueous medium catalysed by transition metal ions. The catalytic oxidation may be carried out simultaneously with the absorption stage (a) or in a separate stage. The oxidation may be effected by bubbling air or O 2  into the solution which contains NiCl 2  or to which NiCl 2  is subsequently added. Alternatively the solution may be sprayed into air. Bicarbonate ions may be provided by dissolving a bicarbonate salt in the aqueous liquid or by reaction of an aqueous carbonate or acid phosphate with CO 2 . This reaction may be effected by passing pure CO 2  into the solution, or by using the CO 2  in the gas mixture to be treated.

Abstract: 1,037,278. Wells; boring earth &c. DEPUTY MINISTER OF MINISTERUL INDUSTRIER PETROLULUI SI CHIMIEI OF RUMANIA. Dec. 24, 1963 [Dec. 28, 1962], No. 50814/63. Heading E1F. Well apparatus for running-in, or pulling, a pipe string comprises: a conveyer 13 for raising a pipe from, or lowering it to, a rack 11 to, or from, a horizontal position midway up the derrick; a trolley 16 at the position for moving one end of the pipe horizontally to, or from, the derrick; an upper lift 2 in the derrick adapted to raise, or lower, the other end of the pipe prior to lowering, or after raising, the string in the well; and a lower lift 7 having make and break mechanism 9 adapted to fix the pipe to, or unfix the pipe from, the string. At the beginning of a cycle for adding a pipe A 2  to a pipe A 3  already in the string which is being run in, both lifts descend and the pipe A 2  is in the midderrick position. While both lifts are descending the weight of the string is taken by slips 10 on the lower lift, an end of the pipe A 2  is gripped by jaws 21 on the trolley, and the conveyer starts to raise a pipe A 1  from the rack. As the upper lift comes to rest opposite the pipe A 2  an elevator 5 on a power swivel 4 carried by the upper lift grips the other end of the pipe A 2 , and the lower lift continues to descend. The upper lift rises rapidly and the lower lift descends, the pipes passing through the positions shown. At the top of the stroke of the upper lift the pipe A 2  is released from the jaws and the now vertical pipe is lowered by the descent of the upper lift on to the pipe A 3 . The lifts descend together and after the make and break device has joined the pipes A 2 , As the weight of the string is transferred to the elevator, swivel and upper lift. The upper lift continues to descend and the lower lift rises rapidly before descending until the top of the pipe A 2  is level with the pipe A 1  which has been raised by the conveyer to the mid-derrick position in readiness for a cycle to attach the pipe A 1  to the string. When the apparatus is used for pulling pipe a transfer unit 22 removes pipe from the horizontal midderrick position and places it on the conveyer. The elevator is replaced by a make-up unit when the rig is used for drilling.

Title: Apparatus and method for using the same to ascertain the angular position of a discontinuity in the medium surrounding a test bore
IPC: G01N23/203
Filed: 1973-11-02
Abstract: 1437244 Testing bores FRIENDS OF THE NEGEV INSTITUTE 2 Nov 1973 [15 Nov 1972] 51106/73 Heading G1A A probe which can be lowered down a bore in a concrete pile to examine the pile for defects has an omnidirectional neutron or gamma ray source and also a detector which responds to backscattered radiation. The field of view of the detector can be limited by a cylindrical sleeve having a longitudinal slit so that by rotating the probe in the bore the angular position of a defect can be found. Fig. 2 shows a pile 10 having a region 13 in which earth 14 is present as a defect. The probe 20 can be lowered down metal or plastic pipes such as 12', 12" cast into the pile, and examines the pile in a region adjacent each pipe. The basic probe is conventional, Fig. 4, and has a tubular housing 25 containing a source, a detector and electronics 28 connected to an electric cable; the source is shielded from the detector. A wire rope 31 supports the probe, though the electric cable can be used for this purpose if it is armoured. To limit the field of view of the detector the sleeve 40 of Fig. 5 may be located around the probe to rest against shoulder 41 (Fig. 4) where it is held by a nut screwed on to part 26. The sleeve is of stainless steel and has a lead lining 43, or is of cadmium depending on whether the source of radiation emits gamma rays or neutrons. The slit 44 defined by the lining may extend over 180. The source is cesium 137 for gamma rays or americium 241 and beryllium for neutrons; neutrons can be detected with a He<SP>3</SP> tube, a fission chamber or a scintillator crystal. To test a pile the probe is first lowered down the bores in turn, without the field limiting sleeve; this allows the depth of a defect to be found. The probe is then raised and a rod is screwed into the top in place of the support rope so that the probe can then be replaced in the bore at the depth of the defect and rotated by the rod. Associated electronics then allow the backscattered radiation to be measured against the direction of view. In another embodiment, Fig. 6 (not shown) the source is concentric with the detector, and emits fast neutrons. The detector responds primarily to the slower backscattered radiation.
