Abstract: 147,774. Apple, V. G. Jan. 22, 1917, [Convention date]. Dynamo-electric machines.-Commutator bars are enclosed in a clip having the outlines of a commutator segment and the clips and conductor terminals are welded into segments. Clips 20 are placed over the terminals 13 of each pair of conductors 11, 12, and fitted between rings 14 and 18 of non-welding material. Through the slots 19 of the ring 18, through the spaces 16 between the clips 20, and into the depressions 15 in the ring are placed separators 17 of non-welding material. The spaces 22 are closed by plugs, and the ends 13<1> of the conductors melted, thus welding the clips and terminals into homogeneous commutator sections. The separators 17 and the ring 18 are then removed, and insulating material is substituted. The armature 10 is cooled in a water tank 26, and the terminals 13<1> are welded by means of a carbon pencil 31 connected as shown in Fig. 4.

Title: A process for the preparation of silicon-containing copolymers
IPC: C08G77/00
Filed: 1950-08-10
Abstract: Copolymers are made by reacting a silane of the formula R2SiX2, wherein R is a monocyclic aryl or alkyl radical, e.g. phenyl, tolyl, chlorophenyl, methyl, ethyl, propyl and octadecyl, and X is a chlorine atom or an alkoxy radical, with an equivalent amount of a dihydric alcohol and reacting the resulting product at 100-300 DEG C. with a polycarboxylic acid or anhydride, in amount such that the ratio of the number of acid functional groups to the sum of the number of silane X radicals plus the number of alcoholic hydroxyl radicals is from 0.01 to 1. The alcohols employed are of the general formula HO.R1.OH, where R1 is a divalent organic radical such as alkylene, phenylene or cyclic alkylene, e.g. ethyleneglycol and trimethylene glycol.  Acids specified are succinic, adipic, oxalic, sebacic, fumaric, maleic, phthalic, mellitic and trimellitic acids. In examples, ethylene glycol is reacted with phenylmethyldiethoxy silane and the resulting product is reacted in example (1) with phthalic anhydride, in (2) with maleic anhydride, and in (3) with fumaric acid; (4) phenylethyldichlorosilane is reacted with trimethylene glycol and the resulting product is then reacted with trimellitic acid.  A strong acid such as HCl or H2SO4 may be used to catalyse the reaction.  Where all three components are difunctional, the products are viscous liquids, and where the acid is at least trifunctional the product may be an insoluble gel.  The products find use as plasticizers for siloxane and organic resins, as paint vehicles and as coatings for electrical conductors.  Specification 663,599 is referred to.

Title: Process for the densification of carbonaceous bodies
Inventor: BLANCHARD RENE
IPC: C01B31/00
Filed: 1963-05-20
Abstract: Carbonaceous bodies whose proportion of pores of diameter less than 0.1 micron, and between 1 and 100 microns, is not more than 10%, and at least 50%, respectively are densified by thermal cracking at 800-1000 DEG  C. of a continuous stream of gaseous hydrocarbons passing over the bodies at atmospheric or super-atmospheric pressure. The hydrocarbons may be saturated or unsaturated, cyclic or acyclic, pure, diluted in inert gas, or a natural gas mixture, particularly methane, cleaned natural gas, or uncleaned natural gas; in the latter case the proportion of pores of diameter 100-500 microns should be 15-40%. Carbonaceous bodies of the required pore distribution are prepared from, for example, petroleum or other cokes, graphite or pyrocarbon of appropriate particle size distribution by admixture with a polysaccharide binder such as gum, mucilate, starch, alginate, molasses or methyl cellulose in an amount such that the binder constitutes no more than 10% of the mixture, addition of water sufficient to produce a plastic paste, shaping of the paste at room temperature at less than 100 bars pressure, drying in air at between room temperature and 100 DEG  C. and carbonizing.  The densified bodies may be graphitized at up to 2800 DEG  C.

Class 44 A band clip for securing an object to a panel comprises a band 21, having one side margin 22 for engagement with the panel 24 and end portions separated by a gap 25 bridged by a connector shoe 26 consisting of a central portion 27 in which a threaded bore is disposed parallel to the clamp axis and from which wings 28 extend having formed therein respective diagonal slots 29 diverging towards the margin 22 engaging the panel, an actuator screw 31 passing through an aperture in the panel and engaging the threaded bore, and means 30 on the band end portions to engage the diverging slots 29 and enable the end portions to be drawn together when the screw 31 is rotated to draw the shoe 26 towards the panel. As described, the end portions of the band 21, which is of hollow channel section, are provided with connector buttons 30 to engage the slots 29. The head 32 of the screw 31 bears against the forward face of the panel so that rotation of the screw draws the shoe towards the panel whilst the buttons 30 exert a camming action in the slots 29 thus tightening the clamp. An anchor fitting 33 is secured to the band 21 diametrically opposite the gap 25 and comprises a threaded bore formed in a body portion 27<SP>1</SP>, and ears 28<SP>1</SP> extending therefrom for attachment to the band.

Abstract: 1340762 Coated roadstone F TUNKL 27 Jan 1971 [18 Dec 1970] 20726/71 Heading C3N [Also in Division B1] A process for producing coated roadstone comprises mixing in the presence of heat an aggregate material having a moisture content, e.g. 5-15% by weight, and a solid bituminous binder in particulate or granular form proportioned to provide a composition requisite for a mix of coated roadstone to be produced, the water content being removed by evaporation at the same time as the binder is liquefied and coats the aggregate, and the dusty constituents of the aggregate material being retained until such time as they are bound into the mix by the liquefied binder. The aggregate and binder may be subjected to a preliminary cold mixing operation. In such a pre-mixing operation the aggregate material may be pre-mixed with molten binder whereby the aggregate cools the binder to cause it to solidify.
