Abstract: 1,240,511. Abhesive coating. IMPERIAL CHEMICAL INDUSTRIES Ltd. 31 July, 1969 [21 Aug., 1968], No. 40019/68. Addition to 1,152,251. Heading B2E. [Also in Divisions C2 and C3] An abhesive coating composition for textiles and paper comprises 100 p.b.w. of a diorganopolysiloxane having at least two hydroxy groups on different Si atoms and a viscosity of at least 3000 cS/25‹C, 1-20 p.b.w. of a monoorgano hydrogen polysilixane of viscosity at most 1000 cS/25‹C, 1-20 p.b.w. of an aminoalkoxy silicon compound and 5-20 p.b.w. of a tin compound YO(R 2 nO) n Y, wherein R is a C 1-20  alkyl group, Y is a hydrocarbyl group or R' R"C=N where R' is H or a hydrocarbyl group and R" is a hydrocarbyl group, and n is 1, 2 or 3, in an organic solvent. It thus differs from Specification No. 1,152,251 in having hydrocarbyloxy or oxime groups on the tin compound, in place of acyloxy groups. In Examples to 66.5 p.b.w. of a 7.5% solution in toluene of a mixture of 100 p.b.w. hydroxyterminated polydimethylsiloxane (10<SP>7</SP> cS/25‹C) and 6 p.b.w. trimethylsilyl-terminated methyl hydrogen polysiloxane is added 0.7 p.b.w. of a poly(aminoethoxy) methyl siloxane (40 cS/ 25‹C) and 0.7-1.4 p.b.w. of toluene solutions of dibutyl dibenzaldoximo tin, tetrabutyl dibenzaldoximo distannoxane, octabutyl dibenzaldoximo tetrastannoxane, dioctyl dibenzaldoximo tin, dibutyl diacetaldoximo tin, dibutyl diacetoximo tin, dibutyl dibenzophenoximo tin, dibutyl diacetophenoximo tin, dibutyl tin diphenoxide, dibutyl tin di-n-butoxide and dibutyl tin di-n-octoxide.

Abstract: 1,201,307. Magnetic pole structure. PERKIN-ELMER Ltd. 7 Dec., 1967 [8 Sept., 1966], No. 40097/66.- Heading H1P. [Also in Division G1] The dimensions of the working gap of a magnet system are controlled by at least one device which changes its geometric shape when electrically energized. A high-permeability pole-tip 3A is attached by an epoxy resin to a carrier 4A and a magnet 2A. The face 5A of the pole-tip is optically flat. The pole-tip 3B is mounted in a similar manner on carrier 4B but is separated from magnet 2B by an air-gap 8. Studs such as 9 are used to restrain the movement of the carriers 4A and 4B whilst a number of piles 13 of lead zirconate-titanate piezo-electric discs 14 are provided between the stud-ends and carrier 4B. The piles of piezo-electric elements can be selectively energized to tilt the carrier plate. The tilt of the carrier plates is adjusted during an NMR test to give the best resolution and hence high field homogeneity. In another embodiment (Fig. 3, not shown) the pile of piezo-electric discs may be mounted directly between the two carrier plates. Quartz discs may be used in the place of lead zirconatetitanate. The flux level in the working gap may be adjusted or modulated by feeding D.C. or A.C. to all the piezo-electric piles. Two airgaps or an air-gap and a non-magnetic spacer may be incorporated in the pole structure.

Abstract: 917,809. Controlling nuclear reactors. GENERAL ELECTRIC CO. Ltd. Nov. 15, 1960 [Nov. 27, 1959], No. 40433/59. Class 39 (4). [Also in Group XXX] A control rod is attached to one end of a flexible driving chain 6, the other end of which is free, the chain passing over a driving sprocket 7 and being maintained rigid by channels 8, 9 in a guide housing 31. The channels 8, 9 are disposed alongside one another, thus reducing the length of the installation. The sprocket 7 is driven by a motor 20 through a sliding key coupling 24 and a worm 22. The coupling 24 is disengageable to enable the motor 20 to be withdrawn for servicing. The reactor is provided with a containment structure which envelops the biological shielding 27 and is formed with a sleeve which not only acts as a location for the motor 20 but also enables the entry into the containment vessel to be sealed by means of a door to which a shielding plug is attached.

Title: Interchangeable viewfinder for a single lens reflex camera

Filed: 1974-09-17
Abstract: 1436830 Interchangeable view-finder arrangements ASAHI KOGAKU KOGYO KK 17 Sept 1974 [20 Sept 1973] 40474/74 Heading G2A  In a reflex camera having an interchangeable pentagonal prism view-finder, the view-finder has electrical contacts which engage with corresponding contacts on the camera body, the said contacts being positioned in front of the third reflecting surface of the prism. As shown, the detachable view-finder 2 is a sliding fit on to the camera body 1. The view-finder housing has a stepped portion 2c in which are mounted a number of connector pins 7, each having soldered to its upper end 7a a lead wire from a circuit element in the view-finder. A number of corresponding connectors 9 are secured to the camera body, these being formed as resilient segments, whose lower ends 9a are soldered to circuit elements in the camera. As the view-finder is fitted on to the camera (i.e. with a sliding movement from right to left as seen in Fig. 1), the pins 7 engage against the upper ends 9b of the connectors 9, and bend them from the Fig. 2 position to the Fig. 1 position, so establishing a good contact. A cover 11 protects the connectors when no view-finder is present, and when this is attached the cover is pushed back. The connectors occupy a space in front of the third reflective surface 4c of the pentaprism 4a which is normally not used, so no increase is caused in the volume of the camera.

Abstract: 1,140,643. Transistors. SIEMENS A.G. 11 Sept., 1967 [12 Sept., 1966], No. 41355/67. Heading H1K. A transistor designed particularly for use in grounded emitter configuration has a surface coating of insulant covering the exposed edges of the emitter and collector junctions and the surface of the base region between them, and the emitter contact extends over this layer from the emitter across the base to terminate above the collector. This extended contact should completely overlie the space charge zone which in use arises adjacent the collector junction, and for this reason it includes a portion in the form of a closed loop following the periphery of the collector junction. The invention, though particularly applicable to planar transistors, is also applicable to other structures, e.g. mesas. It can also be applied to any transistors in an integrated circuit. Fig. 3 shows a plan view of one embodiment in which: lines 9 and 10 indicate the peripheries of the emitter and collector junctions; shaded area 5 is the base contact; and the larger shaded area is the emitter contact which includes a portion 6 breaking through the surface insulant to contact the emitter region and a surrounding portion 7 which overlies the insulant. In Fig. 4 the emitter region 3 is annular and its contact 6 concentrically surrounds the base contact 5. Figs. 2 and 5 (not shown) depict further alternative structures: Fig. 5 is a plan view of a structure similar to that of Fig. 3 except that the generally rectangular shapes are replaced by circular ones; and Fig. 2 is a sectional view of a similar structure to that of Figs. 3 and 5. In any of the structures described the collector contact 8 may be on the opposite side of the wafer to the base and emitter contacts, or on the wafer edge as in Fig. 4, or on the same face as the base and emitter contacts-in which case it may be in the form of a ring contact surrounding the other two contacts.
