Filed: 1968-08-12
Abstract: 1,240,014. Wells &c. TEXACO DEVELOPMENT CORP. 12 Aug., 1968 [17 Aug., 1967], No. 38553/68. Heading E1F. A 9 spot well pattern (which may be one of a number in a production field) has four additional production wells arranged on a line passing through the central well and one of the surrounding wells. Combustion is initiated at the central well and air is injected into it, the other wells in the line being produced. The wells A, B; Y are also produced. When the combustion front reaches the position # 1 and breaks through at the additional wells adjacent the central wall they are converted to air injection wells. As the wells are overrun by the combustion front they are converted to injection wells. After the wells X have been converted, wells Y are overrun and converted, the process being completed when the wells A, B are overrun. In a modification the wells A, B, Y are not put into production until the additional wells and the wells X are converted. In a further modification in which the wells A, B, Y are not put into production until the additional wells and the wells X are converted, the wells A, B are first put into production and converted when overrun, the process being completed on breakthrough at the wells Y. In another modification the additional wells are arranged on a diagonal of the pattern.

Title: Polarimeter apparatus
IPC: G01J4/04
Filed: 1959-11-16
Abstract: 875,278. Photo-electric polarimeters. BECKMAN INSTRUMENTS Inc. Nov. 16, 1959 [Nov. 17, 1958], No. 38699/59. Class 40(3) [Also in Group XX] The polariser or analyser of a polarimeter is angularly oscillated about the position of minimum transmission. Oscillator 22, Fig. 1, oscillates analyser 17 and the output of photomultiplier 18 is fed via amplifier 19 to a phase detector 20 which gives an output with sign indicating the sense of the displacement of the mean position of analyser 17 from the position of minimum transmission. The output is fed to the oscillator 22 to bias the output thereof and so reduce the displacement. Detector 25 derives from the amplifier 19 a voltage representing the amplitude of the second harmonic of the oscillator frequency, which depends mainly on the intensity of source 11, to control the gain of the amplifier. In a modification a partially reflecting mirror is inserted between tube 16 and analyser 17 to provide a comparison beam which is chopped alternately with the measuring beam and applied to the photomultiplier 18. Alternative manual adjustment of the analyser position is described. The analyser is fixed in a member 26, Fig. 2, supported by flexible arms 27. Current from oscillator 22 passes through coils 29 and interacts with electromagnets 32 to rotate member 26. The mean position of the analyser is measured by the current flowing in the coils 29. Alternatively two of the arms 27 are more flexible than the others and the control, by solenoids or a servo motor, applied by arms contacting the ends thereof, is subject to a mechanical step down. A pointer or recording pen may be connected to one of said contacting arms.

Inside the anode is a reflector rod 6, connected to the anode and having a concave head 7. The anode is surrounded by a glass sheath 8 having a diaphragm between the anode and cathode which prevents unwanted discharges. occurring on the outside of the anode and acts as a lens electrode being negatively charged by secondary electrons. On the occurrence of a disruptive discharge, a tubular plasma is formed in the aperture of the anode diaphragm, covering a sufficiently large area of the target 3, wherein the electrons impinging on the anode and the reflector rod are diffused back and subjected to multiple reflection to increase the probability of ionization, further, the hollow anode and reflector form a high frequency tank circuit which is excited by the voltage variation between anode and cathode and by the interaction of injected electrons. The high frequency alternating field developed in the vicinity of the aperature lengthens the electron path and accelerates slow electrons. To increase the probability of ionization the reflector rod can be made of a permanent-magnet material with a high Curie-point. The neutrons formed are withdrawn from the hollow-anode and accelerated to the target. The metal parts are of hollow construction. The ignition pressure for a deuterium filling is 7 x 10<SP>-2</SP> Torr at an operating voltage of 150 kv. An annular electrode 13, electrically connected to the cathode, assists in preventing surface discharges between the fusion points of the anode and cathode. The power-supply comprises a capacitor 9, consisting of a plurality of lengths of high voltage cable in parallel discharging from an electrode 10 to a terminal cap 11 connected to the anode. In a modification, Fig. 3, not shown, the cathode is everted and the glass sheath is not used.

Title: Improvements in the production of porous film
IPC: B29D28/00
Filed: 1966-09-06
Abstract: Porous film is made by perforating a film of polymeric material which has been stretched biaxially to increase its dimensions by 100-600% at a temperature below its softening temperature, and heating the perforated film to shrink it to approximately the initial area. The polymer may be polypropylene, polyethylene which may have been irradiated, polyvinyl chloride or polyvinylidene chloride. Perforation may be performed on individual sheeting or in pads or stacks of sheets, by a uniformly spaced pattern of punches or by flame perforation.  The perforation diameter may be 1.3 mm. and the average maximum dimension of the perforation after shrinking may be 0.2-0.6mm. If the elongation during stretching was the same in both directions, initially round perforations after shrinking will be round; otherwise they will be slits.  The holes may permit passage of liquid water before shrinking but not after; the porous film is, however, permeable to water vapour and oxygen.

Abstract: 1368252 Railway vehicle undercarriages WEGMANN & CO 26 Aug 1971 [27 Aug 1970] 40143/71 Heading B7L A railway vehicle comprises a body 3, Figs. 1 and 2, mounted on a bogie 1 by suspension means including a control linkage consisting of two longitudinal radius rods 4a, 4b each having a spherical joint at each end, one end of each rod being connected to the bogie via a damping coupling at 10, and the other end of each rod being attached to a respective one of two cranks 5a, (5b), which are fast on respective ends of a transverse shaft 7 which is in turn connected to the body 3, said cranks and shaft forming parts of the control linkage. The suspension means are such that on a straight section of railway track the bogie can rotate about its vertical axis only by overcoming an opposing resistance offered by the damping coupling, without at the same time free movement being prevented between the bogie 1 and the vehicle body 3 in the fore and aft, lateral and vertical directions, whereas upon entering a curve the resistance of the damping coupling is overcome. As shown in Figs. 1 and 2, the damping coupling is a multiple disc friction coupling in which friction discs beneath plate 10 are held together by a spring 12 but are separated when rollers 13 ride up inclined parts of a track surface 14 to decompress the discs. Alternatively, as in Figs. 15 and 17, the transverse shaft may be connected to the bogie and the damping coupling interposed between the control linkage and the vehicle body. In Fig. 15, the coupling comprises a roller 71 which engages a depression 73a of a track surface 73 provided on a bolster 70. Fig. 17 shows a fixed centre bogie in which a central pivot pin 91 connects the bogie to the body and is provided with a multiple disc friction coupling 96a, 96b within a bearing member 90, from which longitudinal forces are transmitted to the bogie by a link bolt 97 attached to the bogie at 98 via springs 99. Sprung axle guide means, Figs. 10 and 11 (not shown) may be arranged between the bogie and roller axle bearing housings, comprising spring elements which are arranged at approximately the level of the wheel axles and which include rubber chevrons.

Abstract: 1,248,825. Electron/ion beam tubes. H. WOLLNIK. 12 Aug., 1969 [14 Aug., 1968], No. 40162/69. Heading H1D. [Also in Division G2] A temperature-controlled orifice or slit for optical, ion-optical or electron-optical instruments comprises a plurality of plates having edges defining the orifice or slit mounted on a support having a temperature coefficient of expansion different from that of the plates. In a simple example the plates may be merely screwed to a supporting block having a hole for passage of a beam immediately beneath the centre of the slit. The block may be made of molybdenum and the plates of nickel, copper or aluminium. Both elements are heated from a common source and the combination of materials is chosen to give a required adjustment characteristic. The edges of the plates may overlap and be shaped so as to define a square or rectangular orifice. A number of plates may extend radially inwardly from a circular support and together define a square orifice at the centre after the manner of an adjustable iris. Fig. 6 shows plates 62, 63 defining a slit 65 above hole 69 in support 68. The plates are attached to the support by bimetallic flexural members 66, 67 which determine the width d of the slit. The movement of members 66, 67 may be limited by a pair of stops (118, 119, Fig. 11, not shown) which extend outwardly from the support 68. The slit plates themselves may be formed from a pair of flexural bimetallic laminae (Figs. 9, 10, not shown). In the arrangement of Fig. 3, a pair of plates 32, 33 defining a slit d are attached at A to a further pair 38, 39 of plates which are in turn attached at B to a third pair 36, 37 of plates, these being attached to an apertured support member 31 at C. The pairs of plates and the support are made of two materials which alternate throughout the structure, and which have relatively high and low expansion coefficients. The effect is to multiply the movement of the slit.
