Title: Process for the preparation of a plastic vulcanisable material from rubber, gutta-percha, balata, and the like
IPC: C08L7/00
Filed: 1933-11-20
Abstract: A process for the preparation of a plastic vulcanizable material from non-adhesive powder of non-vulcanized rubber, guttapercha, balata or the like obtained by spray-drying latex with a substance which protects the dried particles against agglomeration, e.g. as described in Specification 388,341, consists either in adding compounding ingredients, such as fillers, vulcanizing agents and accelerators, in the dry state to the dry powder and in rendering the mixture plastic by slight mechanical action, such as by rolling, kneading or pressing, or in mixing the compounding ingredients with the powder dispersed or dissolved in a swelling agent for the rubber, e.g. benzene, petroleum or other mineral oils, the mixture being rendered plastic merely by the swelling action on the rubber, or by a combined swelling and slight mechanical action.  The resulting paste may be spread, plastered or sprayed to the desired shape and vulcanized. The compounding ingredients may be first emulsified or dispersed in a swelling liquid, and this emulsion or dispersion mixed with the powder, e.g. by rolling or spraying.  Latex like suspensions may be made by adding water or other liquid.  The swelling agent may be a normally solid material which melts at or below the vulcanizing temperature.  Preferably a substance which when molten dissolves sulphur is used, e.g. naphthalene. Specification 316,006, [Class 70], also is referred to.

[Also in Groups XVIII and XXIX] A high and low-level alarm for a steam boiler comprises a container 1 connected by pipes 2 to the water and steam spaces of the boiler and housing a float 3 to which is attached a rod 7. The rod is slotted at 6 to engage a pivot-pin on which hinge two arms 5 the arms being pivotally secured to respective links 9 carried on fixed pivots 10. Pivoted links 12 connect the links 9 to bell-cranks 14 which engage a pin 16 carried by a pusher rod 17 extending upwardly through a steam exhaust pipe 18 and into the lower end of a guide tube 20 held within a tube 23 threaded on to the pipe 18. The upper end of the guide tube is formed as a seating for a conical valve 21 which is normally held closed by a spring 22. The tube 23 extends above the valve and contains a throttling orifice 30 gauged to pass just sufficient steam to sound an alarm whistle 26 which is connected to the upper end of the tube 23 by a pipe 25. In operation, with the float at either the lowest or highest permissible level, respectively shown in full and dotted line on the drawing, the links 9 are drawn inwardly by the arms 5 and the pusher rod 17 is forced upwards to open the valve 21 so that the alarm is given. At normal level, however, the arms 5 open, forcing the links 9 apart to retract the pusher rod and allow the spring 22 to close the valve. To prevent crushing of the float by the boiler pressure a predetermined amount of distilled water 31 is introduced into the float, the water evaporating under working conditions to generate an internal pressure which substantially balances the external pressure on the float. In a modification a second steamfeeding pipe is provided through which steam flows when the " low " level is reached to actuate a valve to cut-off the feed of fuel to the boiler fire-box.

Abstract: 1,001,154. Semi-conductor devices. RADIO CORPORATION OF AMERICA. Sept. 12, 1961 [Sept. 27, 1960], No, 32774/61. Heading H1K. A rectifying junction is formed in a semiconductor body of one conductivity type by coating the body and/or a pellet of activator material characteristic of the opposite conductivity type with a material containing at least one compound selected from the siloxanes and compounds of general formula R 1 R 2 SiO, where R 1  and R 2  are aryl or alkyl groups, and subsequently alloying the pellet to the body. Suitable siloxanes are tetraethoxysilane and aryl, ethyl, phenyl and vinyl triethoxysilanes and those of general formula H 3 Si(OSiH 2 ) n OSiH 3  and are conveniently applied as solutions in xylene, benzene, toluene, acetone and propanol. A transistor may be made by first immersing two different sized pellets of indium of spherical, disc or ring form in a solution of dimethyldiethoxysilane in xylene, drying the coated pellets, placing them coaxially on opposed faces of an N-type germanium wafer, and heating the assembly for 10-20 minutes at 550 C. in a non-oxidizing atmosphere. Alternatively the solution may be sprayed on the pelletwafer assembly. Junctions may be formed in a similar way on wafers of N or P-type germanium, silicon and germanium-silicon alloys using boron, aluminium, gallium and indium as acceptors and phosphorus, arsenic and antimony as donors, or on wafers of indium phosphide and gallium arsenside using selenium and tellurium as donors and zinc and cadmium as acceptors. During the alloying processes the applied materials decompose to form a skin of silicon oxide on the pellets which prevents uncontrolled spread of the pellet material over the wafer.

Abstract: 466,500. Railway signalling systems. WESTINGHOUSE BRAKE & SIGNAL CO., Ltd. Nov. 28, 1935, No. 32999. Convention date, July 25. [Class 105] In railway signalling systems with code impulses of current applied to the rails a low resistance shunt path is automatically applied across the rails between the impulses. Any current which may be " stored " in the rails is thus prevented from causing a hold-up of the track relay and interfering with its following the code. A track section 1T is energized whenever a coding relay C closes its front contact 5 to apply a battery 1B to the rails. The track relay 1TR follows the code and repeats the code in a section 2T by applying a battery 2B to the rails of the section 2T ; the battery 2B is applied over a back contact 6 of the track relay 1TR. During the "off" periods of the coding relay C its back contact 5 effects a short circuit across the rails of the section 1T to prevent the track relay 1TR from remaining up. Similarly during the " off " periods of the code current in the section 2T a short circuit is applied to the rails of such section 2T by the front contact 6 of the codefollowing track relay 1TR.
