Abstract: 117,936. Whaley, J. Aug 3, 1917. Four-stroke-cycle engines; driving- gear.-In engines having parallel cylinders connected to and rotating with a central shaft 17, the pistons engage rollers 36 carried by a spider mounted upon a fixed inclined disk 41. The outer plates 31 against which the rollers 36 bear are adjustable to take up wear, and they project into recesses 15 in the cylinders to prevent rotation of the pistons in the cylinders. The spider carries a constraining roller which works in a groove (not ehown). Combustible mixture enters through passages 19, 20, 21 and the burnt gases escape through valves 23 and a passage 24.

Abstract: 759,644. Abrasive tools. MERIT PRODUCTS, Inc. April 21, 1954, .No. 11439/54. Class 60 An abrasive wheel assembly includes an annular pack 12 of juxtaposed flaps and means 19, 20 adhered to said flaps maintaining them circularly disposed around a central circular space, alternate flaps of the pack each having a face coated with an abrasive substance and the intervening flaps each having smooth faces. To form the pack a roll of abrasive cloth one inch wide and a roll of wrapping paper are mounted on parallel spindles from which they are drawn in contacting relation ;by a pair of feed rolls while a mechanically operated knife cuts off pairs of flaps which drop into a receiver. This receiver has an open side portion to enable a fabric strip 19 to be glued to one side of the pack which is then cut into the lengths required. The exposed face of the strip 19 is next coated with an adhesive and assembled to a cylindrical core member 20 of fibreboard or pastboard. Finally, the pack and two annular canvas strips 22, each coated on one face with adhesive. are assembled with the aid of an upstanding cylindrical member which fits within the core 20. The complete pack is clamped on an arber 5 by means of two discs 17 and a nut 27, the arbor having a shank 9 for mounting in a chuck. Specification 759,674 is referred to

Title: Improvements relating to organopolysiloxane elastomers
IPC: C08G77/00
Filed: 1959-04-08
Abstract: The invention comprises siloxane gums in which at least some of the Si-bonded radicals have the formula:  <FORM:0869845/IV (a)/1> where R is an alkylene radical of at least 2C atoms with the S atom being separated from Si by at least 2 C atoms, and R1 is an alkyl or aryl radical, any remaining radicals being monovalent hydrocarbon and/or halogenated hydrocarbon radicals. The preferred gums have the average general formula:  <FORM:0869845/IV (a)/2> wherein a has a value from 0,1 to 2,0 and the sum a+b is from 1,9 to 2,1 inclusive, and R11 is monovalent hydrocarbon or halohydrocarbon radical, and may be homo- or co-polymers.  The sulphone-containing siloxanes may be made by hydrolysing silylthioethers of the formula (R1-S-R)nR112-nSiX2, when n is 1 o 2 and X is an alkoxy radical or halogen atom, with or without conventional difunctional silanes, in water or aqueous acid solution to form lower molecular weight cyclic or linear polymers; the thioether radicals are then oxidized in two stages by a mild oxidizing agent, e.g. H2O2 in glacial acetic acid (HAc), in the first stage 1 mol of H2O2 is added per mol of thioether radicals to form a sulphoxide radical, <FORM:0869845/IV (a)/3> the temperature being kept between 5 DEG  and 30 DEG C., and in the second stage the sulphone is formed by adding further H2O2-HAc solution and heating to 90 DEG -114 DEG C.  The resulting oil is separated, purified and polymerized in known manner to a gum, which can then be compounded with known fillers and curing agents and cured to an elastomer. Examples are given of the above preparation of the sulphone-containing siloxane gums and the curing thereof to elastomers.  Uses: in making gasket material in aircraft fuel lines, shock absorbers, electrical insulation on conductors and in encapsulating electrical apparatus.  The silylthioethers can be made by reacting a mercaptan with a hydrolysable alkenyl silane in the presence of a sodium mercaptide, as disclosed in French Specification 1,118,495, or of ultra-violet light, as disclosed in Specification 869,844 and described in Examples 1 and 4.
