Patent GB-671774-A (GB)
Title: Improvements in or relating to organopolysilanes
IPC: C08G77/00
Filed: 1950-04-26
Abstract: Organopolysilanes, the polymer units of which have the structure R2Si= and in which the units are linked by silicon to silicon bonding, are made by reacting in the liquid phase an alkali metal with a chlorosilane of the formula R2SiCl2, wherein each R is an alkyl radical and at least one R is an alkyl radical containing at least two carbon atoms.  Sodium and potassium are the preferred alkali metals.  The reaction may be effected either by adding the chlorosilane in a solvent, e.g. toluene or xylene, to the finely divided alkali metal or vice versa.  Salt and alkali metal may be separated from the reaction product as by filtering and washing.  The products vary from a grease-like material (diethylpolysilane) to a wax-like material (methyl stearyl-polysilane), and are soluble in warm toluene or xylene but only slightly soluble in the lower alcohols and ketones.  The products may be used for stopcock greases, lubricants, car polishes and shoe polishes.  In examples polymers are made from (1) (C2H5)2SiCl2; (2) (CH3)(C3H7)SiCl2; (3) (n-C4H9)2SiCl2, and (4) (CH3)(C18H37)SiCl2.

Title: Improvements in and relating to brush contact devices for rotatable radio aerials
IPC: H01Q3/04
Filed: 1945-04-26
Abstract: 597,523. Collectors. SJOSTRAND, H. E. April 26, 1945, No. 10545. [A Specification was laid open to inspection under Sect. 91 of the Acts, Oct. 13; 1945.] [Class 38 (i)] The brush of a slip-ring brush contact, suitable for rotatable aerials, is freely mounted so that the angular position of the brush relatively to the slip-ring is wholly determined by the contact surfaces. The brush or slipring is made of a precious metal, e.g, silver, or an alloy of precious metal. In the form shown in Fig. 1, a disc-shaped brush 2 held in a metal holder 3 is mounted universally on the cupshaped end of a spring support 5 which maintains the brush in contact with a plane slip-ring 1. The contact surface of the brush has a central recess so that a steady brush pressure is maintained. In a modification, Fig. 4 (not shown), the brush is of annular shape and the holder has a cup-shaped depression extending into the brush in which the end of the support 5 rests. In a further modification, Fig. 5, the brush 15 is urged into contact with a cylindrical slip-ring 14 by a spring plunger 18 engaging a ball-shaped projection 17 on the brush holder. Alternatively, a rectangular brush may be used which is slidable in a rectangular hole in a stationary support. The brush may be made of soft graphite. Where a graphite brush and metal holder are employed, the two may be joined by a suitable amalgam or the holder may be silvered on the interior and pressed and crimped on to the brush. The brush may be fixed to the holder galvanically.

Title: Improvements in and relating to a device for checking the coining of coins
Filed: 1958-04-02
Abstract: 822,225. Vending machines; coin-testing. SODECO, SOC. DES COMPTEURS DE GENEVE. April 2, 1958 [April 4, 1957], No. 10563/58. Class 27 A device for checking the coining of coins used in automatic vending machines comprises a channel for the coins, two pins 12, 13 between which the coins must pass as they fall in the channel, one of the pins 12 being fixed whilst the other pin 13 is carried at the end of an arm of a lever 7 which, at its opposite end engages a second lever 5, the free end 11 of which is inturned to provide a hook projecting into the channel below the pins 12, 13; the motions of the movable pin and the hooked end of the second lever caused by the passage of a coin through the channel are in opposite .directions and the hooked end of the lever 5 therefore moves inwards to intercept the passage of any coin having a thickness in its central part exceeding a predetermined value. Thin coins 15, which cannot be detected by the device, fall through a narrow slot 16 located at the angle of the channel so that they cannot pass through a branch 17 to actuate the vending machine the lever 7 is mounted so that it rocks in a vertical plane whilst the lever 5 lies in a plane slightly inclined to the vertical axis. The lengths of the lever arms 5 and 7 are so chosen as to multiply by three or four the movement of the pin 13. The passage of a genuine coin is slowed, but not stopped, as the upper portion of line coining contacts the pin 13, the hooked end of the -lever 5 having moved inwards to the face of the coin as the pin 13 contacts the rim. If a forged coin of a thickness equal to the rim thickness of a genuine coin is inserted in the channel, the pin 13 remains in its retracted position and the part 11 remains projected into the slot to prevent the passage of the forged coin. The coin channel may be cleared by outward movement of the wall 1 of the coin shoot about a hinge 18 when a control knob is actuated.
