Abstract: 700,138. Folding paper; delivery apparatus. CHAMBON, Ltd. (Machines Chambon). Nov. 21, 1951, No. 27359/51. Class 100 (1) Interfolding sheets.-A machine for interleaving sheets of paper comprises co-operating rotatable discs 1, 3, having V-shaped recesses 9 for holding the sheets 5, 5' and interleaving them, the interleaved sheets being held in contact with the disc 1 while their movement is changed to a horizontal direction for delivery on a table 27. The disc 1 is rotated on an axis 2 the sheets being held in the recesses 9 by means of suction applied to the bases 10 of the recesses through channels communicating with principal channels 12 communicating with a manifold 13 attached to a suction device. The sheets are retained on the wheel 3 by similar devices including a manifold 13 which extends to a position corresponding to the sheet interleaving position. At the point a blowing manifold 16 communicates with the channels 12 so that the sheets 5 are forced off the wheel 3 onto the wheel 1 where they are held by means of suction channels extending to the points 8 of the recesses 9. A guide 19 is also provided. When the sheets are in a position at the bottom of the wheel 1 they are released by co-operation of the channels 12 with a blowing manifold 15 and are engaged by worms 21, 22 and cooperating worms 23, 24. The worms 21, 22 are of triangular thread and progressively reduced pitch, and worms 23, 24 are of an exactly similar pitch, but shaped so that at one end the base of the thread is above the base 10 of the wheel 1 and at the other is at a distance equal to the height of one folded sheet from the base of the thread of the worms 21 and 22. The sheets are then compressed before being deposited on the table 27 and forwarded by a slow moving belt 26. A reciprocating pusher 25 is provided for aligning the edges of the sheets. Delivering in rounted batches.- For delivering the sheets in counted batches each batch is first formed by the regular interruption of the positioning of sheets on the points of the wheel 1. Several chains 29 passing over drums 30, 32 are provided carrying fingers 33 adapted to be inserted between extreme sheets of successive batches discharged by the machine. When the fingers are in position between the sheets they push the batch against an abutment 37 for removal by a pusher member 35.

Resins specified are colophony, coumarone resin, coumarone-indene and coumarone-styrene resins, phenol formaldehyde resins, maleic acid resins and pentaerythritol resins. Solvents specified are kerosene and tetrahydronaphthalene, and other such oils which do not boil above about 350 DEG C are suitable.  If solutions with a high content of active substance are require, solvents rich in aromatics, e.g. Edeleanu extracts, should preferably be used.  Other solvents which may be employed are hydrocarbon derivatives, such as halogenated hydrocarbons, alcohols, ketones, ethers and esters.  Other insecticides such as 2:2-bis-(p-chlorophenyl)-1:1:1-trichlorethane, hexa-chlorocyclohexane, chlorinated camphene and 1:2:4:5:6:7:8:8-octachloro-4:7-methano-3a:4:7:7a-tetrahydronidane, alkyl thiocyanates, pyrethrum and rotenone may also be present.

EKTNO-KONSTRUKTOR I TEKHNOL INST ELEKTROSVAROCH OBURUDOVANIYA 20 June 1974 27468/74 Heading B3R [Also in Division H2] Plasma arc welding or cutting apparatus comprises an electrode 16 surrounded by a nozzle 12 interconnected by a high voltage, high frequency oscillator 14 operation of which causes a high frequency arc to be produced between the nozzle 12 and electrode 16 which ionizes the gas fed into the nozzle so permitting a pilot arc to be developed between the electrode 16 and nozzle 12, the pilot arc being fed from a thyristor type power supply 15 by way of an RC circuit, the pilot arc being instrumental in the striking of the main arc between the electrode 16 and a workpiece 13 the supply 15 also supplying the main arc by way of an inductor L. With the pilot arc only alight the pilot arc current is determined by the RC combination but when the main arc is struck the capacitor C becomes fully charged whereupon the pilot arc current is reduced and is determined only by the resistor R. The resistor R may be variable and controlled so as to have a minimum value when the pilot arc only is alight and to have a maximum value when the main arc is burning. A switch may be placed in series with the resistor R which is opened when the main arc is struck thereby terminating the pilot arc current flame. A similar mode of operation is obtained by placing a diode in series with the resistor.

Abstract: Hydroperoxides are obtained by the aerial oxidation of hydrocarbons, for example sulphur-and aromatic-free kerosine, paraffin wax, white oils, white spirits and paraffin-enriched fractions obtained from paraffin-containing materials by solid adduct formation with urea or thiourea.  The peroxide-containing material may be concentrated by extraction with a selective solvent In one example 2 kilograms of kerosine are charged into a glass vessel, with 1 cc. of tertiary butyl hydroperoxide as oxidation initiator, and air-blown at 240 DEG C. for three hours. The product is neutralized with sodium or potassium hydroxide and the oily layer washed with water, dried with anhydrous sodium sulphate and the oil then extracted with anhydrous methanol. Methanol is removed under partial vacuum from the concentrated hydroperoxide solution.  The Provisional Specification refers also to organic peroxides in general.ALSO:Mineral oil fractions containing sulphur compounds are purified by reacting at, for example, 50-180 DEG  C. with an organic hydroperoxide under conditions such that oxidation products of the sulphur compounds are formed.  A specified hydroperoxide is tertiary butyl hydroperoxide. Mixtures of hydroperoxides may also be used; these may be obtained by aerial oxidation of hydrocarbons, for example, sulphur- and aromatic-free kerosine, paraffin wax, white oils, white spirits and paraffin-enriched fractions obtained from paraffin-containing materials by solid adduct formation with urea or thiourea.  The peroxide-containing material may be concentrated by extraction with a selective solvent such as methanol.  Removal of sulphur compounds from the treated oil may be effected by adsorption, distillation or by extraction with methanol, aqueous methanol, aqueous acetone, sulphuric acid or caustic soda solution.  The treatment of gas oil is described in the examples.  The Provisional Specification refers also to organic peroxides in general.
