[Also in Division H1]  Curable, sulphur free compositions for covering electric cables comprise a normally solid ethylene/propylene copolymer elastomer and a minor proportion by weight of an organic peroxide, optionally together with an organic dioxime, polyethylene, a vinyl silane and/or carbon black. Preferred peroxides are those in which the peroxy groups are linked to tertiary carbon atoms. The dioxime may be succinaldehyde dioxime, glutaraldehyde dioxime, 2,5- hexanedione dioxime, para-quinone dioxime, para-benzoquinone dioxime, tetrachloro-parabenzoquinone dioxime, 2,5-dichloro-para-benzoquinone dioxime and tautomers such as paradinitrosobenzene and poly-para-dinitrosobenzene.

Abstract: 860,787. Mineral mining machines. MAVOR & COULSON Ltd. March 27, 1958 [April 9, 1957], No. 11458/57. Class 68(1). To enable re-tensioning of an endless cutter chain circulating about a jib to take place as wear occurs there is provided between a jib frame 21 and the support bar 20 therefore a plungercylinder unit 34, 31 that can be expanded and contracted as desired by pumping grease into and releasing grease from the cylinder. To expand the unit 34, 31 grease is pumped through a grease nipple 42 screwed into a non-return valve 41 in a passage 39, 38, 37 extending through the support bar 20. To contract the unit, the valve 41 is removed so that the grease can return from the cylinder 31 as the unit contracts when tension is put on the cutter chain.

Title: Improvements in or relating to the treatment of gaseous mixtures containing acetaldehyde
IPC: C07C47/06
Filed: 1941-09-11
Abstract: Acetaldehyde is absorbed from gaseous mixtures containing it and converted to paraldehyde by means of an inert organic liquid which will dissolve acetaldehyde and paraldehyde in all proportions and which contains an acidic polymerizing agent. Paraldehyde itself is a suitable solvent liquid, but acetic acid and chlorinated hydrocarbons may also be used.  The process may be used for the recovery of acetaldehyde from the exit gas in the oxidation of acetaldehyde to acetic acid or acetic anhydride, and when the solution of acetaldehyde to be oxidized contains a small quantity of polymerization catalyst such as sulphuric acid, a part of the reaction liquor may be withdrawn from the reaction chamber, cooled, and used as scrubbing liquor to recover acetaldehyde from the exit gases as formaldehyde.

Title: Improvements in or relating to track apparatus for actuating signals on trains
IPC: B61L3/10
Filed: 1934-04-20
Abstract: 419,124. Track apparatus for actuating signals on trains. COMPAGNIE DU CHEMIN DE FER METROPOLITAIN DE PARIS, 75, Boulevard Haussmann, Paris. April 20, 1934, No. 11946. Convention date, May 8, 1933. [Class 105.] Different signals are given on a train by track ramps energized with normal or reverse direct current in conjunction with an alternating current of half the voltage. The normal or reverse pulsating or steady currents select different combinations of rectifier-fed relays Ra, Rb, Rc on the locomotive whereby one particular signal relay alpha is operated to release a spring contact v which lights a lamp l and operates a recorder a. The relay Ra is energized by the pulsating ramp current flowing through a transformer T2 the secondary of which is mid-tapped and provided with two rectifiers ro so that both half waves are utilized. The relays Rb, Rc being provided with oppositely arranged rectifiers ro are respectively energized by normal and reverse currents either steady or pulsating. These relays are fed over a rearwardly arranged brush AR. A forward brush AV on encountering a ramp causes a relay Ro to lift its contacts the upper of which opens the line to the relays Ra, Rb, Rc whilst the lower energizes windings B to re-set the spring contacts v in readiness for the rear brush AR to transmit the next particular signal indication. The normal or reverse current is applied to the ramp by a reversing switch B and the alternating current is applied by a switch R1. The direct current for the ramp is provided by a tricklecharged battery A. The signal relays alpha are only energized after a time interval depending on the resistance p and the condensers y ; thus the contacts of the relays Ra, Rb, Rc must be definitely positioned. The apparatus may be arranged so that a further signal is given by applying only the alternating current to the ramp.
