Title: A releasing device for a locking mechanism in wire line core drills
IPC: E21B23/02
Filed: 1969-07-02
Abstract: 1,248,863. Boring earth; releasable fastenings. ATLAS COPCO A.B. 2 July, 1969 [2 July, 1968], No. 33365/69. Headings E1F, E2A and E2B..  A wire line core drill has a locking mechanism by which the inner core tube 4 can. be connected to or released from a support on the end of a wire. The tube 4 carries a.latch 1 pivoted at 7 and biassed by a spring 3 so that its bottom hook end 9 engages a recess 10 in the drill pipe 5 to hold the core tube down. The tube is retrieved by dropping down the drill pipe a weight 18 (on a wire) carrying a shaft 23 with a tapered head .2 which engages the upper end 14 of the latch to pivot the latch out of engagement with the recess 10 and also to support the core tube 4 on the face 2a of the shaft head, for retrieval. The head 2 is released from the latch under conditions of excessive tension in the shaft (e.g. when the core tube is irretrievably stuck), by downward movement of a sleeve 12, which is permitted by the release of a catch 8 which is normally retained within an inclined slot 16 (Fig. 2A) in the sleeve 12 by a torsion spring 13. The relative upward movement is made possible by a compression spring (e.g. a stack of spring washers 19). The core tube is lowered down the drill pipe with the catch 8 disconnected, so that when the bottom of the pipe is reached, the support moves downwards relative to the core tube 4 and the flanged end 17 of the sleeve 12 passes the latch end 14 to release it from the head 2. The catch 8 may be replaced (Fig. 5; not shown) by an arrangement in which the sleeve 12 enters a bore in the body of the support, and is retained there, until a predetermined force is applied, by an 0-ring-fitting aligned grooves in the sleeve outer surface and the bore wall.

Title: Friction welding method and apparatus
IPC: B23K20/12
Filed: 1963-08-29
Abstract: 1,057,672. Welding by pressure. GARRETT CORPORATION. Aug. 29, 1963 [Aug. 30, 1962], No. 34258/63. Heading B3R. In friction welding an axial impact is produced between the contacting faces to cause them to weld. A rotary motor (12), Fig. 1 (not shown), e.g. an air turbine, drives a sleeve (24) mounted in a bearing (22) through gearing (18), (26) and a splined shaft (30) slidable in the sleeve and rotatable therewith carries at its righthand end a work holder (40) and is connected at its left-hand end to the piston of a doubleacting hydraulic device (36). An air turbine (14) similarly drives through gearing (20), (46) a sleeve (50) in a bearing (42) and a splined shaft (48) adjustable in the sleeve and rotatable therewith carries on its left-hand end a work holder (52). Air is supplied to the turbines through a solenoid valve (56) operated by a control system (60) and hydraulic fluid is supplied to the device (36) through a solenoid actuated control valve (62). In operation the handle (62a) of the valve (62) is moved to a position in which the device (36) moves the shaft (30) to the left, the parts (P 1 ) and (P 2 ) to be welded e.g. a turbine wheel and shaft respectively are mounted in the work holders, the work holder (52) is adjusted to its correct position and the motors (12), (14) are started by a control (60a) to rotate the parts (P 1 ), (P 2 ) in opposite directicns. When the parts have acquired a relative angular velocity of 14,000-74,000 r.p.m. as sensed by sensors (68) on the motors the control system operates the valve (62) to cause the device (36) to drive the shaft (30) to the right and the part (P 1 ) to impact with the part (P 2 ). The relative rotation continues until the plastic state is reached, the part (P 1 ) is retracted out of contact with part (P 2 ) and is then immediately driven again to impact with the part (P 2 ) which produces welding diffusion of the interfaces. The bond produced tends to stall the motors (12), (14) and the control system cuts off air supply to the motors which stop. In a modification the apparatus of Fig. 1 has an additional impact device (202), Fig. 3 (not shown), which includes a ram (204) for striking an anvil (208) on the shaft (48). In the operation of this apparatus the parts (P 1 ), (P 2 ) are brought up to speed and into initial impact exactly as before and the parts are rotated to bring the interfaces to the plastic state. The ram (204) is then driven into impact with the anvil (208) to produce a bond between the parts which causes the motors to stall and to be stopped as before. The relative angular velocity of the part may be such at initial impact that the impact and frictional heating which occur simultaneously create a bond. Where dissimilar metals are to be joined a welding alloy may be applied to one or both of the interfaces.

Title: Process and apparatus for the production of nitric acid
IPC: C01B21/26
Filed: 1936-12-14
Abstract: <PICT:0481629/III/1> In obtaining nitric acid from gases containing nitrogen oxides and oxygen by oxidising the oxides to the tetroxide stage and absorbing the tetroxide in water and aqueous nitric acid, the gases, after initial oxidation substantially completely to the tetroxide stage, are treated in a series of small chambers, in each of which the gases remain for a maximum period of about 10 seconds, for absorption by nitric acid of progressively decreasing strength whereby the concentration of the tetroxide is progressively diminished until it is completely extracted, and are thereafter passed into a larger chamber for the oxidation of nitric oxide formed during absorption to tetroxide for further complete absorption treatment, so that the gases as they enter the oxidation chambers contain practically no tetroxide.  Gases, containing nitrogen, oxygen and nitrogen tetroxide (say ammonia oxidation gases) pass in succession through a series of small absorption chambers 2-8, an oxidation chamber 9, a second series of small absorption chambers 10-12, an oxidation chamber 22, a third series of small absorption chambers 13-15, an oxidizing chamber 23, and a final series of small absorption chambers 16-18, the spent gases issuing from the plant at 19.  The successive oxidation chambers 9, 22 and 23 are gradually increased in size.  Water or a weak acid solution is admitted at 21 to the final absorption chamber 18 and after circulation by a pump 26 overflows into the absorption chamber 17.  The acid is circulated jointly in the chambers 15 and 17 by a pump 27, overflows into the absorption chamber 14, is circulated jointly in the chambers 14, 16, 12 and 8 by a pump 28, overflows into the absorption chamber 7, is circulated jointly in the absorption chambers 7, 11 and 13 and the oxidation tower 23 by a pump 29, overflows into the absorption chamber 6, is circulated jointly in the absorption chambers 6 and 10 and the oxidation chamber 22 by a pump 30, overflows into the absorption chamber 5, is circulated jointly in the absorption chamber 5 and oxidation chamber 9 by a pump 31, and thereafter the acid passes successively through the absorption chambers 4, 3 and 2 to issue from the plant at its maximum concentration at 20.  According to another modification a battery of seven small absorption chambers is directly succeeded by five large towers of progressively increasing size which serve as combined absorption and oxidation towers.  Water or weak acid enters the last combined tower and passes successively through circulations embodying the fourth combined tower and the seventh small absorption tower, the third combined tower and the sixth small absorption tower, the second combined tower and the fifth small absorption tower and so on, finally issuing from the first absorption tower.
