Title: Depth gage for boring machine
IPC: B23Q17/09
Filed: 1957-10-29
Abstract: 870,377. Indicating-apparatus. LEBLOND MACHINE TOOL CO., R. K. Oct. 29, 1957 [April 17, 1957], No. 33645/57. Class 106 (4). [Also in Group XXII] A boring-machine having a slide 22, carrying a boring-bar 24 and means 40 for indicating the depth of the bore, comprises an indicating means which indicates the movement of the slide in each direction, a unidirectional means which indicates only the depth of feed, and means for coupling the two means together if a predetermined depth of feed is reached. Movements of the slide 22 are conveyed to the indicating means 40 by a cable 42, which is wound on a drum 64 by a spring 70, thus rotating gears 60, 58 and a shaft 56. The shaft 56 carries a conical member 74, which can be clutched to a plate 80 by tightening a screw 90, and a pointer ring 86. The plate 80 is biased by a spiral spring 94 and carries an arm 96 to actuate a switch LSI at the end of a return movement of the boring slide. When the ring 86, Fig. 5, rotates, a projection 112 thereon engages a pin 110 on a frictionally-mounted pointer ring 100, 102, thus carrying the two rings round in unison. If the rotation of the ring 86 is reversed, the ring 100, 102 remains in its advanced position. However, when the boring-slide approaches its full depth feed position a fixed pin 118 pushes down a spring hook 114 on the ring 100, 102 to engage a pin 116 on the element 86 so that, on reversal, both rings return to the initial position. The ring 100, 102, carries a projection 120 to actuate a switch LS-2 just before boring is complete. A stationary calibrated dial 54 indicates at any moment the length yet to be bored in the workpiece.

Title: Improvements in and relating to halogenated hydrocarbon compounds
IPC: C08F114/00
Filed: 1934-11-26
Abstract: Compounds suitable for use as dielectrics are manufactured by heating halogenated olefines, e.g. trichlorethylene, di- or tetrahalogenated ethylene, or halogenated propylene or butylene, with aluminium chloride at a temperature sufficiently high to cause polymerization to occur.  The products, alone or mixed with other insulating products, particularly other halogenated compounds, e.g. chlorinated diphenyl, chlorinated diphenyl oxide, chlorinated diphenyl ketone or chlorinated diphenylmethane, may be used as dielectric materials in transformers, capacitors, switches, cables and electric bushings.  In an example, trichlorethylene is heated with aluminium chloride at about 85 DEG  C. to produce a liquid polymerization product.  By heating for a longer time, preferably with a larger proportion of aluminium chloride, there is formed a resinous product which may be used as a dielectric material alone, or mixed with trichlorbenzene, trichlorethylene or the liquid polymerization product of the latter. Specification 394,776, [Group XXXV], is referred to.

Title: Improvements in or relating to the production of cellulose ethers
IPC: C08B11/193
Filed: 1936-12-17
Abstract: Mixed ethers of cellulose are obtained by reacting a partially alkylated cellulose, containing at least 0,5 molecular proportions of an alkyl group having less than 3 carbon atoms for each glucose unit of the cellulose, with an alkyl halide containing from 8 to 18 carbon atoms in the presence of an alkali. Cellulose may be subjected to partial etherification by reaction with ethyl or methyl chloride or sulphate, the cellulose being preferably in the form of alkali cellulose.  Mixtures of alkyl halides corresponding to mixtures of alcohols produced from coconut oil by catalytic hydrogenation including the mixture of alcohols known under the Registered Trade Mark " Lorol," or mixtures of alkyl halides corresponding to the alcohols obtained by reduction of sperm oil acids, including the mixture of alcohols known as Stenol, may be employed as etherifying agent for the second stage.  The reaction with higher aliphatic alkylating agent may be carried out at elevated temperatures.  In an example alkali cellulose prepared in presence of a wetting agent is heated in two temperature stages with a mixture of ethyl chloride and "Lorol" chloride until a partially ethylated cellulose is produced. The reaction mass is then further heated at a higher temperature in order to effect reaction with the "Lorol" chloride.  The product is precipitated and washed with acetone.  In another example, alkali cellulose is heated with a mixture of ethyl chloride, octyl chloride, and kerosene in two stages.  In other examples, the higher aliphatic chloride is added to the reaction mass after formation of methyl or ethyl cellulose, or the ethyl cellulose is isolated from the reaction mass and then treated with the higher aliphatic chloride and caustic soda. Bromides or iodides may be used instead of chlorides.  Besides the alkyl halides from hydrogenated coconut oil or hydrogenated sperm oil, mixed alkyl halides corresponding to the alcohols obtained by reduction of the mixed acids resulting from the hydrolysis of other oils and fats may be used.  The products are soluble in kerosene, hot paraffin, toluene, methanol, dioxane, or other solvent, depending on the proportion of higher and lower alkyl groups present.  They may be used in the production of lacquers, and plastics.
