Title: Polysiloxane compositions
Filed: 1951-03-06
Abstract: Elastomeric polysiloxanes are made from a readily deformable or organic solvent-soluble acid polymer of at least 2000 cs. viscosity at 25 DEG  C. and composed of a polysiloxane having 1.9 to 2.1 alkyl or alkyl and phenyl radicals per silicon atom, at least 50 per cent of the radicals being alkyl radicals, and phosphorus pentoxide, sulphuric acid, metaphosphoric acid, pyrophosphoric acid, orthophosphoric acid or an ester of an acid of pentavalent phosphorus which contains at least one acidic hydrogen, e.g. ethyl and diethyl phosphates, in amount such that the atomic ratio of P to Si or S to Si is from 1 : 50 to 1 : 50,000, by compounding the polymer with a filler in amount of 5 to 300 parts by weight per 100 parts of polymer and reacting the compounded material at 25 DEG  to 300 DEG  C. with an alkoxy silane of the general formula RnSi(OR1)4-n or a liquid partial hydrolysate thereof, where R is a monovalent hydrocarbon radical free from aliphatic unsaturation, R1 is an alkyl radical of less than 9 carbon atoms and n is 0 or 1, the alkoxy silane or hydrolysate thereof being used in amount such that there is at least one molecule of silane or hydrolysate thereof per two P or S atoms. The acid polymers may be made either by polymerizing organopolysiloxanes with the acidic compounds until the desired viscosity is obtained, or by effecting polymerization with an alkaline catalyst or a metal salt until the desired viscosity has been reached and reacting the resulting polymer with the acidic compound.  Polymers specified are dimethyl-, phenylmethyl-, diethyl- and di-isopropyl-polysiloxanes and copolymers thereof, and they may contain RSiO 3/2 and R3SiO 1/2 units. Fillers specified are cork, cotton linters, wood flour, silica aerogels, fume silicas, asbestos, TiO2, ZnO, Fe2O3, Cr2O3, clay, diatomaceous earth and carbon black. Alkoxy silanes specified are ethyl-, methyl-, propyl- and octyl-orthosilicates and methyltriethoxy-, phenyltrimethoxy-, propyltributoxy-, octyltriethoxy- and tolyltributoxy-silanes and mixtures thereof.  Partial hydrolysates specified are (R1O)3Si.OSi(OR1)3, <FORM:0687759/IV (a)/1> <FORM:0687759/IV (a)/2> <FORM:0687759/IV (a)/3> <FORM:0687759/IV (a)/4> and <FORM:0687759/IV (a)/5> A solvent such as a nitrile, hydrocarbon, ether or alcohol may be added together with the silane to the compounded material. Examples are given.  The resulting materials may be used for making gaskets and electrical insulation.

Title: Improvements in or relating to processes for the manufacture of shells for needle roller bearings
IPC: B21D53/12

Abstract: 876,596. Making roller bearing shells. SCHAEFFLER, W., and SCHAEFFLER, G., [trading as INDUSTRIEWERK SCHAEFFLER O. H. G.]. Feb. 20, 1958 [Feb. 20, 1957], No. 5624/58. Classes 83 (2). In a process of making a shell for a needle roller bearing, the shell having axial openings with a width over the middle portion smaller than the diameter of the needles and a width over the end portions greater than the diameter of the needles, the middle portion of a tubular element having a wall thickness about half the diameter of the needles is radially inwardly offset e.g. by rolling, Fig. 2 (not shown), so that the outer surface coincides with the pitch circle of the needles, openings with a middle portion of reduced width are stamped out, Figs. 3 and 4 (not shown), and the lateral surfaces of the remaining webs are bevelled as at 10, Fig. 5, by externally acting punch means e.g. a punch 9 so that when assembled the needles will be located on the pitch circle. In a modification the openings having a constant width greater than the diameter of the needles are stamped out from a tubular element, Fig. 6 (not shown), and then either simultaneously or separately the middle portion of the remaining webs are radially inwardly offset as before and the lateral surfaces of the webs are bevelled by means of externally acting punch means to provide a seating for the needles as before. When the offsetting and bevelling are done simultaneously the width of the punch is greater than the width of the opening. In another modification, Fig. 7, shell openings 13 are stamped out of a tube with a width equal to the needle diameter throughout the length of the opening, the end portions being calibrated by a punch 14 which tapers over its whole length, Fig. 8 (not shown), and which simultaneously forms the inclined surface 15. The openings may be stamped in the tube before or after the middle portion of the shell is offset. If the openings are stamped out before offsetting, the offsetting and bevelling of the webs may be carried out simultaneously, the punch having a width greater than the width of the openings. In this case a mandrel 17, Fig. 9, coacts with the punch 14.

[Also in Group XXXV] In a vehicle lighting system clockworkoperated mechanism is arranged to switch on the parking lights at a preset time, the clockwork-operated switch being arranged in parallel with the normal parking light switch. In an unattended vehicle the time at which the parking lights are to be switched on is preset by movement of an indicating hand 29 of an alarm clock mechanism. Rotation of a gearwheel 12 associated therewith causes the gearwheel 12 to move laterally along its shaft 14, such movement causing a lever 22 to pivot about a fulcrum 24 thereby to close contacts 16, 20 arranged in the parking light circuit, these contacts being in parallel with the normal parking light switch. Contacts 16, 20 are maintained closed by means of a trigger mechanism 31 which overrides the end 22a of the lever 22 under the influence of a spring 34. The trigger mechanism 31 and hence the contacts 16, 20, are reset by means of a manuallyoperable release 36. Any play between the lever 22, gear-wheel 12 and the switch assembly is taken up by a screw 26 arranged at an end of the lever 22.
