Title: Method of measurement of pressure in explosion phenomena and device for the practical application of said method
Inventor: BERGER JEAN
IPC: G01L23/00
Filed: 1962-11-26
Abstract: 968, 532. Electric selective signalling. COMMISSARIAT A L'ENERGIE ATOMIQUE. Nov. 26, 1962 [Dec. 6, 1961], No. 44669/62. Heading G4H.  In a pressure-measuring device, the pressure to be measured is transformed into a plurality of different pressures in known ratios to it, each acting on a measuring sample mode of a material having a discontinuity in conductivity at a pre-determined threshold value of pressure. Fig. 4 shows one of a plurality of detector units which are  mounted on one or more reference plates 16 (all of the same material), the pressure being applied from below in Fig. 4. The pressure may be that of a shock wave from an explosion. In each detector unit, the pressure is changed in a given ratio by a pastille 15 (of a different material in each detector unit) and acts on the measuring sample 14 (of the same material, e.g. sulphur or paraffin, in each unit). If the threshold is exceeded, the change in conductivity is detected by electrodes 19, 20 and signalled to an oscillograph. Since the shock wave may displace the pastille 15 relative to sample 14 so that it short-circuits electrodes 19, 20, a contact probe is placed between pastile 15 and sample 14 (via channel 21) and detects (and displays on the oscillograph) the arrival of the shock wave. Thus this short-circuiting cannot be mistaken for exceeding the threshold, there being two signals spaced apart on the oscillograph when the threshold is exceeded and one otherwise. The oscillograph is triggered by a contact probe 22 actuated by movement of plate 16.

Abstract: 1,138,407. Slip ring assemblies. NORTH AMERICAN AVIATION Inc. 3 Oct., 1967 [7 March, 1967], No. 44918/67. Heading H2E. A slip ring assembly comprises a hollow insulating shaft 33 with conductive bands 40, the sole means constraining shaft 33 from radial movement, at least when the axis is not abnormally displaced, being the contact wires 33 to 39 carried by brush blocks 30 to 32 and contacting the shaft tangentially at the conductive bands. As shown the wires are arranged in pairs along the axis of shaft 33. Substantial axial movement is prevented by end caps 45 and 49 on housing 42 which have a clearance of a few thousandths of an inch between them and the ends of shaft 33. To limit radial movement there is a similar clearance between a protruberance 46 on cap 45 and the inside of shaft 33, and between shaft 33 and a circular cut out 50 in end cap 49.

Abstract: 1,015,816. Making waveguides; bending; brazing. VARIAN ASSOCIATES. Nov. 14, 1963 [Dec. 17, 1962], No. 45077/63. Headings B3A, B3E and B3R. [Also in Division H1] In forming a slow wave structure for a travelling-wave tube a strip of molybdenum 23 having a transverse grain structure with respect to its longitudinal axis is passed through a stamping die assembly 24, 25, Fig. 2, to remove preselected portions 26, 27. The resulting structure is bent to U-shape in a forming die assembly 28, 29, Fig. 3, and then to cylindrical shape in a forming die assembly 31, 32, Fig. 4. The cylindrical structure is placed on a mandrel 37 in a firing jig, Fig. 5, comprising halves 36 secured together by screws 38 and fired in a hydrogen furnace to produce a stress relieved structure which is transferred to a brazing jig 39, Fig. 6, and a brazing mixture 40 applied to the portions to be joined, brazing being effected in a hydrogen furnace. Other materials such as copper, stainless steel, titanium or columbium may be used to produce " ring and bar " structures or other slow-wave structures, e.g. contrawound helices or structures of rectangular crosssection. With a material other than molybdenum the stress relieving step may be omitted. Instead of performing the initial operation of removing preselected portions of the strip by stamping or punching, this operation may be performed by discharge treatment or by etching. The cylindrical configuration may alternatively be obtained using a cam die assembly, and the brazing step may be omitted to produce slotted structures.
