Abstract: 913,155. Electric holding devices. WARING, R. W., and KENNY, J. E. April 1, 1959 [April 9, 1958], No. 11127/59. Class 35. [Also in Group XXXVI] A method of making a semi-conducting body comprises impregnating a porous insulating body with a carbon-rich material dissolved in a solvent, the boiling point of which is substantially above the decomposition temperature of the carbon-rich material, heating said impregnated body to a temperature sufficient to decompose said material but substantially below the boiling point of the solvent and subsequently heating the body to a temperature sufbcient to evaporate the solvent and to form from the carbon-rich material a conductive material within the pores of the body. The porous body is preferably of aluminium silicate having a resistivity greater than 10<SP>10</SP> ohm centimetres. The carbon-rich material is preferably a specified solution of sucrose in glycerol. The impregnation is preferably done at an elevated pressure and temperature, the pressure being reduced during part of the process to release entrapped air. The impregnated body is heated in an atmosphere of nitrogen, or helium. The high-conductivity outer surface is then ground off. The resistivity may be controlled by further heating. The finished semi-conductive body may be vacuum impregnated with synthetic resin, polymerized in situ. Two such bodies may be cemented together with epoxy resin. The finished body is suitable for use in electrostatic apparatus for producing mechanical force between the body and a conducting or another semi-conducting body.

Title: Improvements in indicating devices for photographic cameras comprising exposure-regulating means
IPC: G03B17/20
Filed: 1964-03-18
Abstract: 1,019,404. Camera exposure control systems; indicating means. BERTRAM, E. AND BERTRAM, W.; [trading as ERNST UND WILHELM BERTRAM, FABRIK PHOTOTECHNISCHER MESSGER€TE]. March 18, 1964 [March 18, 1963], No. 11364/64. Heading G2A. A camera with an automatic photo-electric exposure control system has an indicating device by which colour signs appear in the viewfinder to show the possibility of picture taking often the automatic setting of one exposure factor and the manual preselection of the remaining factors by rotation of the galvanometer 2 of the photoelectric device. A translucent plate 5 is secured to the galvanometer pointer 3 behind a light entry 6 and is marked with diaphragm scales 9,10,11, 12 in sectors of different radii, one side 13 being coloured red and the other side having a further red area 15 which partly covers the scales, the scales themselves being green. A mirror 7 reflects part of the illumined scale into the viewfinder and dependent on the film sensitivity and exposure time, is adjustable radially of the galvanometer axis 14, so that all sectors may be selectively covered. The opposite end of pointer 3 cooperates with stepped cylinder 18 pivoted at 17 and a pointer brake (not shown) for the automatic control of the diaphragm lever 20. Rotation of the galvanometer causes radial movement of mirror 7 through the interaction of control cam 23, fast with the galvanometer, and pin 24 on a-swinging arm 25 pivoted at 26 and engaging at the other end in slot 28 of the mirror-carrying plate 29. Plate 29 is carried on rod 30 which is spring-loaded and is held in frame 31 pivoted at 32. The galvanometer 2 is coupled through a differential setting device to controls for manually setting film sensitivity and shutter speed before the diaphragm is automatically set. If the lighting is inadequate part of the red area is seen and is optionally allowed for by the manual alteration of the shutter speed and hence the mirror position.

Title: Organo-silicon compounds
Inventor: POLLOCK JOHN MACLELLAND
IPC: C08G77/00
Filed: 1959-04-03
Abstract: Organosilicon polymers containing the repeating unit <FORM:0888938/IV (a)/1> where R represents the hydrocarbon radical of an organic di- or tri-isocyanate and R1 is a tertiary butoxy or a phenyl radical, may be made by reacting a di- or tri-isocyanate with ditertiary butoxy silane diol or with diphenylsilane diol or with a siloxane derived from the butoxy-diol and having terminal Si-bonded OH groups, separating the product of reaction and, if desired, heating it to effect further polymerization.  In Examples (1) a benzene solution of di-t-butoxysilane diol and ethanol (as chain terminator) was slowly dripped into a hot benzene solution of hexamethylene diisocyanate and the mixture was then refluxed for 6 hours with subsequent removal of solvent to yield a faint green coloured viscous liquid which cured at 120 DEG C. to a tough, flexible, transparent film; (2) diphenylsilane diol was reacted with hexamethylene diisocyanate in the presence of dibutyltin diacetate; and (3) di-t-butoxy silane diol was polymerized by refluxing in benzene and the resulting polymer was then reacted with hexamethylene diisocyanate, as above.  Other isocyanates are specified and aminosilanes are mentioned as reactants.

Filed: 1932-04-21
Abstract: 393,059. Window regulators. HOBSON, Ltd., H. M. and GREENHALGH, F.,47, The Vale, Acton, London. April 21, 1932, No. 11461. [Class 20 (iii).] Relates to vehicle-window regulators of the kind in which pivoted parallel links a, b, Fig. 1, control the vertical path of the window f and prevent it from tilting: According to the invention, the link a carries a sliding locking member a<5>, Figs. 3 and 5, which is unlocked by the initial movement of the operating handle a<10> and effects the rotation of the links upon a continued movement of the handle. In the form shown, the links are pivoted at one end to a fixed bracket c and at the other end are connected to a bracket d carrying bowls d<3>, d<4> which run in a horizontal guide e attached to the window. The member a<5> is connected to the link a by a pin-and-slot connection a<3>, a4, and is formed at its lower end with teeth a<6> which engage with a segmental rack c<1> on the bracket c. The handle a<10> is rotatably mounted on a pin all and is formed integrally with a boss a<9> and cam a<8>, which latter engages in a D-shaped recess in the member a<5>. Initial movement of the arm a<10> in either direction releases the teeth a<6> from the rack c<1> and further movement effects the raising or lowering of the window. Locking is automatically effected, when the arm is released, by a spring g which is connected to the member a<5> and to the bracket c. This spring also serves to counterbalance the weight of the window. Specification 384,491 is referred to.

Title: Improvements in and relating to the welding of metal and alloy studs, tubes and the like to metal and alloy plates and the like
IPC: B23K9/20
Filed: 1944-09-14
Abstract: 613,981. Electric welding. MARTIN, B. Sept. 14, 1944, No. 11492/48. Divided out of 613,907. [Class 83 (iv)] [Also in Group XXXV] In an apparatus for electric arc welding metal or alloy studs, tubes &c. to metal or alloy plates or other bodies by moving a chuck carrying the stud &c. towards and from the plate &c., the duration of the arc formed between the stud &c. and the plate &c. is controlled by the rate of functioning of an electric condenser included in a control circuit, whereby the movement or movements of the chuck during welding may be automatically controlled. The stud may be first contacted with the plate as described in Specification 156,836, [Class 83 (iv)], or may be first set spaced from the plate. The stud 84 is carried by a chuck 8 which may be withdrawn from the plate 90 against the action of a spring 58 to strike the arc when the coil 24 of an electromagnet is energized by closing auxiliary contacts 74 when the main welding contactor 72 is closed by completing the circuit containing the coil 71 by a push button 70. The circuit of coil 71 contains a safety switch 63, 68 for causing opening of the welding circuit after the coil 24 is de-energized. The duration of the arc is timed by a condenser charging and discharging device. By closure of the contacts 74 current passes through a regulating potentiometer 75, time adjusting variable resistance 76 to coil 78 and also charges condenser 79. When the condenser is charged, coil 78 is energized to lift the plunger 80 to open contacts 81, 82 to deenergize coil 24 and discharge the condenser with the arc still maintained. Forward motion of the stud &c. by the spring 58 opens the switch 63, 68 and cuts off the welding current. The stud may be alternatively moved pneumatically. Specification 613,907 also is referred to.
