Title: Templet positioning tool
Inventor: COOPER FREDERICK HENRY EDWARD
IPC: H05K13/00
Filed: 1966-04-29
Abstract: 1,090,369. Holding tools. STANDARD TELEPHONES & CABLES Ltd. April 29, 1966, No. 18856/66. Heading B4W. Adhesive templets in the shape of circular or elliptic washers are transferred to printed circuit boards by a tool comprising a cylindrical stem 8 having at one end a handle 9 and having an axial bore which guides a spring-loaded needle 10 having a point which protrudes-from the other end of the stem 8. A helical compression spring 13 located in a cavity in the hand grip acts upon a collar 12 which is non-adjustably fixed to the upper end of the needle. The spring 13 forces the collar against the wall 14 at the bottom of the cavity so that the needle protrudes from the stem. A number of templets are positioned and held frictionally on the stem 8 and the tool is positioned by means of. the needle point 11 at a desired point on the printed circuit board where the centre of the templet is required to be located. The tool is then pressed against the surface to retract the needle into the stem and the lowest templet is slid down the stem by a pair of tweezers or other suitable means.

Title: Improved Process and Apparatus for the Automatic Regulation of the Supply of Fuel in Multiple Cylinder Internal Combustion Engines.
IPC: F02D39/02
Filed: 1917-12-21
Abstract: 116,073. Naamlooze Vennootschap Appingedammer Bronsmotorenfabriek. May 18, 1917, [Convention date]. Regulating.-The liquid-fuel supply to a multicylinder engine is controlled by thermostats in the exhaust pipes. The thermostats comprise copper or other rods a which slide in tubes on the exhaust pipes and engage the undersides of devers b carrying at their free ends bell-cranks d which regulate the positions of the fuel-admission valves x. The bellcranks are connected together by a transverse rod e, to which motion is transmitted by a governor h through a bell-crank f, carried by the arm b of the central cylinder, and a lever (not shown), the free end of which is engaged by the free end of the bell-crank f. Any variation in the temperature of the gases in the exhaust pipes of one of the end cylinders raises or lowers the bellcrank d and thus controls directly the degree of opening of the corresponding fuel valve. Any variation in the temperature of the gases in the exhaust pipe of the central cylinder alters the position of the corresponding arm b which adjusts the position of the rod e and thus the positions of the bell-cranks d in such a manner that the fuel supply to the central cylinder remains unaltered, the supplies to the two outer cylinders being adjusted to conform to the supply to the central one. The resulting variation in speed brings the governor into action to adjust the fuel supply of all three cylinders simultaneously. The control of the fuel supply to the central cylinder is thus indirect. According to a modified construction, the rods a may engage levers which actuate the arms b.

[Class 40 (iv)] In a hearing-aid device in which a permanent magnet and coils are mounted on a vibratory member adapted to be placed in contact with the mastoid or other bone, a casing which encloses the magnet and coils is secured relatively to the vibratory member by means at one end of the casing which clamp the casing to the vibratory member and means at the opposite end which clamp the vibrating member to the casing. The vibratory member 6, which is shaped to conform to the mastoid bone, is secured to the casing 7 by a screw 10 passing through the member 6 and at the opposite end by a pair of screws 8 which pass through the casing 7 and engage threaded holes in metal blocks 9, Fig. 4, formed integrally with the member 6. The magnet is of laminated form and comprises portions 12 of rectangular form carrying pole pieces 13 of truncated triangular shape with extensions on which are mounted bobbins 14 for the coils. The outer end of each pole piece has a brass block 17 secured to the magnet by screws 16 and to which is secured by a screw 19 a rectangular diaphragm 15 of soft iron, e.g. Swedish iron.

The external leads 24 are inserted into holes near the base of the members 9 and are pierced by grub screws 25 from which connection to the coils is established by screws 23. Spring washers may be incorporated between the diaphragm 15 and the plate 6.

Title: Polythioformaldehydes
IPC: C08G75/10
Filed: 1963-05-14
Abstract: Polythioformaldehydes consisting essentially of -CH2S- units are prepared by heating formaldehyde, in any known form, with H2S and removing the water of reaction as it is formed.  The products have a molecular weight greater than 172 and up to about 360, and a softening point of 70 DEG  to 240 DEG  C. Removal of the water is preferably effected azeotropically with the aid of a suitable auxiliary liquid, e.g. benzene, toluene, xylene, dioxane or 2,6-di-methyl-dioxane-1,4. The H2S may be diluted with an inert gas, e.g. N2 or CO2.  Examples illustrate the preparation of HS-(CH2S)4-H and HS-(CH2S)7-H; these products can be converted to higher molecular weight polymers by heating with catalysts (see Division C3).ALSO:Polythioformaldehydes consisting essentially of -CH2S- units are prepared by heating formaldehyde, in any known form, with H2S and removing the water of reaction as it is formed.

The H2S may be diluted with an inert gas, e.g. N2 or CO2.  To obtain products with molecular weights greater than about 360, the polymer is subjected to supplementary heating, preferably in the presence of a catalyst at 50-100 DEG  C.; suitable catalysts include strong bases such as aqueous NaOH or KOH, and BF3 and its addition compounds optionally together with acetic anhydride. This treatment to increase molecular weight may be carried out as a separate step or may be effected in situ during polymerization. The polymers are suitable for use as rubber vulcanization agents.
