Filed: 1972-10-12
Abstract: 1430587 Soldering FULMER RESEARCH INSTITUTE Ltd 3 Jan 1974 [12 Oct 1972] 47046/72 Heading B3R  In bonding two parts selected from Ti alloy, Nb, Nb alloy, Ni alloy and stainless steel, an interlayer selected from Mg, Sn, Al/Cu composite and Al is interposed between the parts, the assembly is heated while under pressure to cause the formation of a liquid phase due to melting of the interlayer material or of a eutectic mixture formed between the interlayer material and either of the parts to be bonded, the amount of interlayer material being such that no insoluble intermetallic compound is formed, and the pressure and temperature is maintained until the liquid phase has diffused into the parts. Each part may be of Ti alloy, Nb, Nb alloy or Ni alloy when the interlayer is of Mg, Sn or Al and Cu composite and when both parts are of Nb, Nb alloy or Ni alloy the interlayer may be of Al. A Ti alloy, Nb or Nb alloy part may be joined to a stainless steel part using Mg or an Al and Cu composite. The interlayer may be in the form of a foil or a layer produced by electro or vapour plating or by evaporation and joining, e.g. to form a T joint may take place in an atmosphere of argon or helium or in vacuo. In examples two pieces of Ti-6Al-4V alloy are assembled with (a) Mg and (b) Sn foil and the assembly is pressed and heated for 24 hours in vacuo at 870‹ C. In another example the foil employed is a composite roll bonded Al and Cu foil layer, a greater pressure being employed but for only 1 hour. One of the Ti alloy pieces is replaced by a Nb piece when heating is effected at 900‹ C. for 1 hour and in another example two pieces of Ni- Cr-Co-Ti-Al alloy are assembled with Mg foil and heated under pressure at 900‹ C. for 24 hours.

Abstract: 1,130,369. Valves. DEMCO Inc. 8 Nov., 1965 [23 Aug., 1965], No. 47306/65. Heading F2V. The spindle 6 of a butterfly valve is connected by a hollow pin 17 to a hub 16 carrying a handle 35, the hub and spindle being rotatable by the handle through an arc defined by a pin 33 carried by the hub and; moving in a slot in a fixed plate 15. The valve may be locked in any one of a number of intermediate positions by depressing a lever 74 to cause a pin 21 to enter one of a series of overlapping holes arranged in an arc in plate 15, the lever being connected to the rectangular head of the pin 21 by a pin 61 and having a camming action relative to a surface of the hub and being biased to the locking position by a spring 20. When the lever is depressed, a spring clip (85) may be inserted through aligned holes 80 in the lever and through the hollow pin 17. In the embodiment of Fig. 7, locking is achieved at any intermediate position by rotating a nut 97 to cause an enlarged head 100 of a bolt 95 to bind against the upper surface of an enlargement of an arcuate slot that replaces the series of overlapping holes.

Title: Novel unsaturated aldehydes
IPC: C07C47/20
Filed: 1963-11-13
Abstract: The invention comprises acetalized aldehydes of the formula <FORM:1059675/C2/1> wherein the bond shown as a broken line is optional, n is 0 or 1 and R is a dialkoxymethylene group, the alkoxy groups containing 1-4 carbon atoms.  The diethoxy derivatives of compounds in which n is 0 are made by treating the Grignard derivative of 3-methyl-penten - (2) - yn - (4) - ol - (1) with ethyl orthoformate to give 1,1-diethoxy-4-methyl-hexen-(4)-yn-(2)-ol-(6) which is subsequently oxidized to the aldehyde.  The diethoxy derivatives of compounds in which n is 1 are made by reacting 3 - methyl - penten - (3) - yn - (1) - ol - (5) with methylmalondialdehyde in a Grignard reaction, followed by acid treatment to yield 2,6-dimethyl-8 - hydroxy - octadien - (2,6) - yn - (4) - al - (1), optionally subjecting this acetylenic compound to partial hydrogenation to give the triene, acylating the free hydroxy group, converting the aldehyde group to a 1,1-diethoxy group with ethyl orthoformate, hydrolysing the acyloxy group to the free hydroxy group and oxidizing this 8-hydroxy compound to the required aldehyde. Examples relate to the preparation of 1,1 - diethoxy - 4 - methyl - hexen - (4) - yn - (2) - al - (6); 1,1 - diethoxy - 2,6 - dimethyl - octatrien - (2,4,6) - al - (8); and 1,1 - diethoxy - 2,6 - dimethyl - octadien - (2,6) - yn - (4) - al - (8).  The acetyl derivative of 2,6-dimethyl-8-hydroxy - octatrien - (2,4,6) - al - (1), obtained in the cisas an intermediate in Example 2, is isomerized to the trans-form by treatment with iodine and sodium thiosulphate.

Abstract: 1,017,094. Particle spectrometers. KABUSHIKI KAISHA HITACHI SEISAKUSHO. Dec. 21, 1962 [Dec. 25, 1961], No. 48453/62. Heading H1D. In a charged particle spectrometer, the particles are deflected by a homogeneous magnetic field in accordance with their different momenta and are selectively projected into different detectors the outputs from which are delayed by a mutually different time and introduced selectively into different channels of a multi-channel analyser to be measured. As shown, the field associated with a magnetic pole 1 causes charged particles such as Beta rays from a source 2 to be selectively projected into radiation detectors 4 1 , 4 2 , 4 3 . The output from detector 4 1  is amplified by a pre-amplifier 5 1 , and one portion of the amplified output is applied to a time analyser 11 over a main amplifier 8 and a pulse height selector 10 whilst another portion is applied to the analyser 11 over delay circuits 6 1 , 6 2 , 6 3 , a main amplifier 7 and a pulse height selector 9. The analyser 11 produces a signal corresponding to the time difference between the input pulses received from the elements 9, 10, and this signal is applied to a multi-channel recorder 12 where it is recorded in the channel corresponding to the detector 4 1 . The output from the detector 4 2  is applied to the analyser 11 over the two delay circuits 6 2 , 6 3  and that from detector 5 3  over the delay circuit 6 3  only. The detected time differences in the analyser 11, and consequently the magnitude of the signals generated in response to these time differences, thus differ in correspondence with the detectors 4 1 , 4 2 , 4 3  and are introduced selectively for analysis into different channels of the recorder 12.

Abstract: 1299834 Lasers UNITED STATES ATOMIC ENERGY COMMISSION 25 Oct 1971 [16 Nov 1970] 49491/71 Heading H1C A laser pulse is produced by using a light trigger source to explode ClN 3  in a gaseous mixture including a fluorine compound and molecular hydrogen or a hydrogen compound, the explosion taking place in an optical resonator and causing dissociation of the fluorine compound, followed by a lasing reaction involving the combination of the dissociated fluorine with hydrogen. No chemical contribution is provided by the explosive reaction to the consequential reactions producing stimulated emission. The fluorine compound may be NF 3  or SF 6 , and the hydrogen compound may be HCl, HBr, H 2 S or H 3 N. Preferred examples of suitable gas mixtures are 24 mole/cent ClN 3 , 19 mole/cent SF 6  and 67 mole/cent H 2 , and 25 mole/cent ClN 3 , 25 mole/cent NF 3  and 50 mole/cent H 2 , the former mixture being in a pressure range of 12 to 24 torr and the latter at a pressure of 20 torr.
