Abstract: 501,274. Washer boxes. HIRST, A.A., and SIMON-CARVES, Ltd. Aug. 18, 1937, No. 22638. [Class 82 (ii)] A jig-washer comprises a baffle spaced in position from the outlet and disposed transversely to the flow of coal or other material through the washer box so that one grade of material passes over the baffle and the other grade passes under. In the form shown in Fig. 2, the baffle plate 18 is arranged in the flow of liquid and is supported by rods 19 from a horizontal bar 20 rigidly fixed to the box. A further plate 23,is attached to the baffle 18 so that the effective area of the baffle can be altered. By means of the counterweight 26 the baffle may be inclined at an angle or the baffle may swing freely. An adjust-. able flap 27 is arranged to dip in the water in front of the baffle. The flap and baffle may be perforated. In the arrangement shown in Fig. 4, several baffles 18 are suspended from a frame 33 itself suspended by rods 34 and the whole weight counterbalanced by the weights 40. The rods 35, 36 are con. nected by rods (not shown) to the bar 42 on the shaft 43 so that the cam 44 causes the baffles 18 to oscillate in unison. The oscillations may synchronize with the pulsations of the water. These oscillations may be such that the baffles are lowered as the water rises. Rollers and guides may be provided at the side of the box for the oscillating structure and each baffle may oscillate independently or one or more may remain stationary.

Title: Polymerisation of unsaturated compounds
IPC: C08F2/00
Filed: 1964-06-04
Abstract: Non-gaseous monomers having the formula <FORM:1000688/C3/1> in which R1 is hydrogen or an organic radical and R2 is an organic or inorganic radical are polymerized by subjecting a mixture of said monomer together with a catalytic amount of an aluminium alkyl compound <FORM:1000688/C3/2> where R is alkyl, R1 is H, Cl or alkyl and R11 is H or alkyl, provided that when R1 is Cl, R11 is alkyl, to initiation of the polymerization by exposing the mixture to oxygen, but before the polymerization is complete excluding oxygen from the mixture and allowing the polymerization to proceed to completion in the absence of oxygen.  The oxygen barrier may be gaseous, e.g. nitrogen, carbon dioxide or a noble gas may be used, or it may be liquid, e.g. any hydrocarbon which evaporates slowly at normal atmospheric conditions of temperature and pressure and does not react with the aluminium alkyl compound may be used, or it may be solid, e.g. mica, wax or any fine powder which does not react with the aluminium alkyl compound may be used.  The oxygen barrier may be formed in situ or added subsequent to the initiation of the polymerization reaction.  The aluminium alkyl compound is preferably complexed with saturated or unsaturated esters of monocarboxylic acids having 1 to 20 carbon atoms.  The storage life of the monomer mixture may be increased by adding maleic or substituted maleic anhydrides. To increase the polymer yield, acrylic acid may be added. In the examples, ethyl acrylate, n-butyl acrylate and t-butyl acrylate were polymerized in the presence of acrylic acid and maleic anhydride using as catalyst diisobutylaluminium hydride complexed with butylacrylate, the oxygen barriers being paraffin wax, mica powder, n-heptane and nitrogen.

[Class 40 (iv)] In a system in which a routiner controls the advance of a selector switch, such as of the type described in Specification 447,767, to a special test position by marking in the ordinary test bank and also prevents the switch stopping on idle lines by connecting a busy potential to its test wiper, this potential is connected over a front contact of a high-speed relay TA, such as of the type described in Specification 405,436, [Group XXXVII]. The marking potential is applied over a de-energizing winding of the relay TA so that when the test position is reached the relay removes the busy potential from the test wiper and modifies the marking potential in time for the test relay HB of the switch to fall back and stop it. With TA energized, the marking potential is sufficiently close to earth to busy the test position to other switches. The potential divider from which the marking and busy potentials are derived includes a rectifier MRB, to prevent the busy potential from short-circuiting the booster battery if any lines encountered are in the act of metering, and a rectifier MRA, to prevent any slowing of the release of relay HB by the shunt effect of the potential divider.
