Abstract: 1358570 Two-part couplings WESTFALISCHE METALL INDUSTRIE KG HUECK & CO 23 Aug 1971 [25 Aug 1970] 39489/71 Heading H2E A plug 2 for use with cylindrical sockets has at least one laterally projecting contact 21 and a body formed to present at least two corner portions 13, 14 such that physical contact with the socket 1 is made in at least three places for stability. One such plug for use with sockets of two different diameters comprises insulating body halves 10a, 10b forming a generally triangular cross-section lower body portion 11 and an upper body portion 12 of a smaller cross-section (which may be circular rather than triangular) from which projects a spring loaded contact pin 9 connected by a spring 7 to nut 27 carried by the screw 8 which holds the body halves together. Integrally formed resilient contact arms 21, 22 are arranged for contacting the inner wall of the respective socket. The contact arms 21, 22 may be formed from a series of juxtaposed thin sheets (20a, 20b, 20c, Fig. 2, not shown). Leads 4, 5 are connected to the contacts by screws 6, 8.

Title: Improvements in bore hole survey devices
IPC: E21B47/06
Filed: 1962-10-19
Abstract: 978, 007. Measuring pressure electrically; pressure gauge. SOC. DE PROSPECTION ELECTRIQUE SCHLUMBERGER. Oct. 19, 1962 [Nov. 24, 1961], No. 39673/62. Headings G1L and G1N. Apparatus for measuring the pressure difference in a liquid at two levels a predetermined distance apart comprises two measuring bellows communicating with a differential bellows, whereby the effects of temperature changes, axial acceleration and impacts are eliminated. As shown, for determining the density of liquid 6 in a borehole 8, a cylindrical probe 4, is provided with three coaxial, cylindrical chambers 12, 14, 16. The first chamber 12, located at the bottom of the probe 4, contains a bellows 22 fixed to the upper face 21, the chamber being in communication with the external liquid 6. The second chamber 14 also contains a bellows 24 fixed to the upper face 23 and is also in communication with the external liquid 6. The upper chamber 16 is in communication via pipe 48 with bellows 22, and contains a third bellows 28 communicating with bellows 24 forming two fluid-tight systems equal in volume, each of which is completely filled with kerosene. Thus any change in temperature in the borehole has equal effect on bellows 22, 24 and only the pressure difference between the bottom of bellows 22, 24 causes expansion or contraction of bellows 28, which may be recorded locally, or measured by a differential transformer 36 whose core is attached via rod 34 to the movable upper part of bellows 28. This pressure difference is proportional to the ratio of the density of the borehole fluid to that of the kerosene at the known ambient temperature. Axial acceleration and shock impacts on the probe produce equal effects on bellows 22, 24 and are therefore cancelled out in bellows 28. All three bellows are constructed of metal.

Abstract: 1,273,799. Optical range finder. EASTMAN KODAK CO. 8 Aug., 1969 [8 Aug., 1968], No. 39785/69. Heading H4D. Specification describes a split image range finder, i.e. one in which the lower half of an observation frame Fig. 4 is occupied by a direct view of a scene and the upper half is occupied by a view of said scene, as seen from a laterally offset position A, Fig. la, and presented at said frame by a hinged mirror M2 and upper half frame mirror Ml, the range being given by the necessary orientation of mirror M2 to obtain alignment of the scenes, Fig. 3, provided with photo-electric means detecting said alignment, said means comprising a plurality of pairs of photodiodes 1, 2, 3-(n-1), n, arranged along the shear axis of the frame, the two diodes of each pair viewing respectively different halves of the frame and producing equal outputs for the infocus condition of Fig. 3, differential connections of said diodes, Fig. 5, enabling preamplifiers 30/36 to give voltages of -0À1 v. and +0À1 v. for infocus and out of focus conditions respectively and sense amplifiers 38/44 to give corresponding 0 and 1 outputs. Logic circuits 46 &c. detect when all of the diode pairs are equally illuminated i.e. all amplifiers 38/44 give 0 outputs and an infocus condition prevails, and causes activation of a focusing lens controlling motor M when a departure from the above condition is detected. NOR gate 46 gives a 1 output when all the amplifier (38/40) outputs are 0 which output is applied to input C and (via inverter 52) as a signal 0, to input 5 of JK flipflop 54. The logic circuitry comprising JK flipflops 54, 56, NOR gate 60, clock generator 62 and inverter amplifier 64 operate such that the out of focus (F= 0) condition energizes relay 68, closing contact 74 and energizing motor M. The in focus condition may be defined by some number, less than all of the diode pairs, giving balanced outputs. A circuit utilizing each a definition is shown in Fig. 6 (not shown).

[Also in Division B5] A rubber sole is vulcanized to an upper on a last 15 by compressing and liquefying the sole mixture in a mould 14 with pressure and heat and then allowing the mixture to expand in dependence upon the gas force P 4  in the mixture to an adjustable predetermined volume. The compression of the sole mixture by a ram 13 is effected by a force P 1  and limited by a nut 22 coming into contact with a stop 20. In addition to the force P 4  the expansion may be effected by a release of the pressure force P 1  and/or by a counter pressure force P 2 . The amount of expansion is determined by an adjustable nut 19 and a spring-loaded stop 16. After the completion of the vulcanizing the ram is returned to the initial position by increasing P 2  and/or decreasing P 1  to overcome the spring force P 3 . Specification 958,152 is referred to.
