Title: Improvements in and relating to pressure butt welding apparatus
Inventor: BURTON JOHN EDWARD
IPC: B23K11/04
Filed: 1950-09-01
Abstract: 706,406. Welding. NATIONAL RESEARCH DEVELOPMENT CORPORATION. Dec. 3, 1951 [Sept. 1, 1950], No. 21581/50. Class 83 (4) In a pressure butt welding apparatus comprising a hydraulic press wherein the application of pressure to the work is automatically controlled by the thermal expansion and subsequent shortening of the work, one set of elements attached to the work remote from the joint or to a part movable to follow dimensional change of the work and another set attached to a relatively fixed part of the apparatus control hydraulic means to apply after a low initial pressure, firstly a higher intermediate pressure to overcome thermal expansion and secondly a final high pressure to make the weld. In one embodiment two short tubes 4, 4 are placed between a fixed part of a frame and a hydraulic ram 3. An electric motor driven constant delivery pump 1 supplies oil to the ram 3. An adjustable relief valve 2 and normally open solenoid operated valves 6, 6A are supplied from the supply line to the ram 3, the discharge from the valves 6, 6A being controlled by bleed valves 8, 8A to a tank 9 which keeps the pump 1 free. A water cooled oxyacetylene burner 10 which may be oscillated about the tubes 4, 4 is moved with the ram 3 by means of a rack 20 attached to the ram 3 and acting on a pinion 19 secured to the burner 10 and the burner, 10 is supplied with fuel from a solenoid operated valve 11. Micro switches 7A, 7, 12 and 25 on a fixed part of the frame which operate the valves 6A, 6, 11 and the motor of the pump 1 respectively are actuated by contact with abutments 28A, 27, 27 and 28 attached to the ram 3. In operation with valves 6, 6A open and thus low pressure applied to the ram 3, heating of the tubes 4, 4 causes expansion thereof causing actuation of switch 7A and closing of valve 6A to apply intermediate pressure to the ram 3. On returning to the original position the switch 7 is actuated to close valve 6 and thus apply final high pressure determined by relief valve 2. Then operation of switches 12, 25 causes closing of oxyacetylene valve 11 and stopping of the pump 1. In a modification an apparatus for welding long pipes comprises three hydraulic pressure units comprising rams fixed to an end plate and cylinders attached to a further end plate slidable on the rams. The tubes are held in the end plates. Movement of the burner and operation of the controlling switches is in a manner similar to that in the first embodiment A solenoid operated gas valve and mixer for the oxygen and acetylene is described.

Title: Extraction of metal values from aqueous media
Inventor: FLETCHER ARCHIBALD WILLIAM
IPC: C01G1/00
Filed: 1961-06-16
Abstract: Mercury, silver, lead, cadmium and tin values are extracted from aqueous media, and copper values are extracted from aqueous media containing copper and zinc values, by contacting the media with a solution of naphthenic acid in an inert solvent, immiscible with the aqueous medium, the aqueous medium being at a pH value not more than 0.5 of a pH unit below the pH value required to precipitate the metal to be extracted, and stripping the extracting medium of the extracted values.  The naphthenic acid may be dissolved in benzene, toluene, or xylene or mixtures of aliphatic hydrocarbons such as white spirit or kerosene.  The extraction of the metal values may be selective by adjustment of the pH, and the metal values are stripped by contacting with dilute mineral acids.  Alternatively all the metal ions are extracted and the stripping stage is made selective by adjustment of the pH.  Examples describe the extraction of mercury from aqueous mercuric chloride, silver from aqueous silver nitrate, lead from aqueous lead nitrate, cadmium from aqueous cadmium chloride, tin from stannous chloride and of copper from a solution of zinc and copper sulphate.  Specification 915,428 is referred to.ALSO:Metal naphthenates are used in a process for the extraction of mercury, silver, lead, cadmium and tin values from aqueous media and for extracting copper values from aqueous media containing copper and zinc values.

Title: Improvements in band receiving systems for wireless telephony and the like
IPC: H03H7/01
Filed: 1928-07-28
Abstract: 294,939. Vreeland Corporation, (Assignees of Vreeland, F. K.). Aug. 1, 1927, [Convention date]. Coupling aerial and detector circuits; thermionic amplifiers and detectors; filter circuits.-A wireless receiving-circuit is given a flattopped characteristic, enabling it to respond equally to the carrier wave and its side-bands, by the use of a filter circuit, Fig. 1, comprising two similar series-tuned sections X1, X2 forming a closed circuit with a low reactance X3 connected across the junctions a, b of the two sections. The circuit has two resonant frequencies, one F1 corresponding to the natural frequency of each branch X1, X2 and the other F2 differing from F1 by an amount depending on the value of the reactance X3. This difference varies in sign according as the reactance X3 is a capacity (C3) or an inductance (L3); and the frequency difference bears the same ratio to the natural frequency F1 as C1 bears to (C3) in the one case, or as (L3) bears to L1 in the other case. The combined effect is to produce a flat-topped characteristic with steep sides as shown in Fig. 3. The filter circuit may be interposed between an aerial circuit and all untuned circuit feeding a detector valve. Alternatively, as shown in Fig. 5, it may be placed between an aerial A and a multistage high-frequency amplifier A1 - - A3. The condensers C1, C2 of the filter circuit and the tuning - condensers of the amplifiers may be simultaneously controlled; and the tuning at the several stages of the amplifier may differ slightly in order to pass the complete band. The aerial A is fixedly coupled by a coil P of few turns to the input coil L1 of the filter, and the output coil L2 of the filter has a variable coupling with the coil S. A suitable form of the latter coupling is shown in Fig. 4a, the coil S being operated by a linkwork in such a way that it is withdrawn from the coil L2,in an axial direction, and is then swung into a position with its axis perpendicular to that of the coil L2. The tendency of the aerial capacity to unbalance the two sections of the filter is compensated by adding condensers Cc, Cx in parallel with the filter condensers C1, C2 and by adjusting one of them until the balance is restored. In Fig. 6, one of the filter inductances is represented by a loop aerial L1 with a small adjustable coil Lc in series. Filter circuits of the same type are employed as inter-valve couplings between and after the high-frequency amplifying valves. All the filter condensers are linked together for simultaneous adjustment.

Title: Automatic feed for rock drills
IPC: E21B44/08
Filed: 1935-08-02
Abstract: 440,625. Percussive drills. CHICAGO PNEUMATIC TOOL CO., 6, East 44th Street, New York, U.S.A. Aug. 2, 1935, No. 21988. Convention date, Sept. 1, 1934. [Class 124] A feed for a rock drill is of the reaction type, so arranged that a rearward blow of the piston produces a forward feed. The feed mechanism is contained in a casing 32, 33 and 34 mounted on the end of the feed screw 28. When the steel is free from the rock face the forward blow produces forward movement but opposite rotation of the feed screw is prevented by the pawls 48a acting on the ring 40. When the steel engages the work it prevents forward blows on the drill body, and backward blows therefore produce backward movement of the screw 28 compressing the spring 70 and rotating the ring 80 splined to engage the helical flutes 76. The end of a spring 85 enters a notch in the ring 80 and allows this to rotate in one direction but opposite rotation is prevented by the spring expanding against the casing 82. Hence when the spring 70 expands the screw 28 is rotated to feed the drill forward. A shaft 57 has three angular positions, to engage pawls 48a for forward feed, to engage pawls 48b and release casing 82 for backward feed, and to release all these for hand positioning. The cam handle 100 adjusts the pressure between the brake surface 109 and the ring 40 to adjust the rate of feed.
