Abstract: 1284062 Feeding cards or tape to a punching machine SOC INDUSTRIELLE HONEYWELL BULL 27 Jan 1970 [29 Jan 1969] 3993/70 Heading B4B [Also in Division F2]  Cards or tape 1 are fed stepwise to punches (not shown) by a roller 3 on a shaft 4 to which at least one ratchet wheel, e.g. 5 is fixed, the ratchet wheel being indexed by a pawl 11A pivotably mounted on a lever 7 which can pivot about the axis of the shaft 4. The pawl 11A is moved on the lever by a cam 14, rotated with a shaft 15 and engaging a follower 13 on an arm 12 fixed to the pawl 11A, the pawl being retracted from engagement with the teeth of the ratchet wheel by an electromagnet 24. The follower 13 is urged against the cam by a spring 16 which also urges a freely revolvable friction roller 20 against a second cam 21, rotated by the shaft 15. The cam 21 imparts a rocking motion to the lever 7 causing the pawl 11A to index the ratchet wheel 5. When the electromagnet 24 is energized, it attracts the pawl 11A on to a self-lubricating non-magnetic support 26, the polepieces 22, 23 and support having part cylindrical surfaces concentric with the shaft 4 to allow the retracted pawl to rock when out of engagement with the ratchet teeth. Two ratchet wheels 5, 6 having corresponding pawls 11A, 11B may be provided, the pawls being rocked by identical cams 11A, 11B set 90 degrees out of phase.

Title: Improvements in means for indicating a condition in a filter for fluids
Inventor: WORTH THOMAS CLAUD
IPC: B01D35/143
Filed: 1957-02-06
Abstract: 835,286. Filters. BRITISH FILTERS Ltd. Jan. 31, 1958 [Feb. 6, 1957], No. 4046/57. Class 46. [Also in Groups XXVIII and XXIX] Hydraulic fluid is pumped at 1 from an inlet 2 along line 8 to auxiliary inlets 9 located near the inlet ends of filters 3 (which communicate at 4 and 5 with the hydraulic circuit of an aircraft) and emerges from auxiliary outlets 10 which, however, communicate with the inlet spaces outside the filter media in the filter casings. Initially, when the fluid temperature is low, the fluid is too viscous to pass through the filter media, so that pressure is low at the main filter outlets 5 and in consequence the pressure of the fluid emerging at 10 and acting through a conduit 16 on a piston 13 in a valve 12 is able to overcome the pressure of a spring 14 and the main outlet pressure applied therewith (along conduit 11). Fluid therefore passes out through a port 17, through an auxiliary filter 18, and back along conduit 19 to the pump inlet. Eventually the fluid, heated by compression, is able to pass through the filter media of the filters 3, whence it flows along a conduit 6 past a non-return valve 7 to the main hydraulic circuit and back to the filters at 4. Flow in the main circuit is restricted so that the main outlet pressure rises sufficiently to close the valve 12 and flow along conduit 19 ceases. This pressure (the operating pressure) is indicated on a gauge 20. If the filters are clogged they will not permit hydraulic fluid to pass even when the casings are warm, so that valve 13 remains open and pressure in line 11 (and therefore line 8) does not rise, and the fact is indicated by gauge 20. The piston valve may be replaced by a bellows valve. The auxiliary filter 18 retains large particles detached from the elements in filters 3 by the preliminary circulation of fluid past them.

Title: Process for the cyclic production of hydrogen peroxide
IPC: C01B15/023
Filed: 1958-02-10
Abstract: In the production of hydrogen peroxide by a process involving alternate reduction and reoxidation of a starting material comprising an alkyl anthraquinone, the starting material comprises a mixture of 2-amyl anthraquinones prepared from fusel oil (see Group IV(b)).  The process comprises catalytic reduction with hydrogen of the anthraquinones in a solvent medium, oxidation with air or oxygen of the reduced solution after removal of the catalyst, thereby regenerating the anthraquinones and simultaneously producing hydrogen peroxide, and recycling of the oxidised solution to the reduction stage after extraction of the hydrogen peroxide with water.  The tetrahydro nuclear derivatives accumulate in the solution on repeated recycling.  The catalyst may be palladium or Raney nickel.  The solvent medium may be (a) a -methyl-naphthalene, alone or in admixture with di-isobutyl carbinol, (b) butyl benzoate, (c) octyl alcohol, or (d) a mixture of equal parts of di-isobutyl carbinol and xylene.  A table, and an example specifying solvent, concentration, and extent of hydrogenation, are given.  Specification 465,070 is referred to.ALSO:A mixture of 2-amyl anthraquinones for use in the production of hydrogen peroxide (see Group III) is prepared by the successive steps of (a) dehydrating fusel oil at a temperature of 340 DEG C.-360 DEG C. in the presence of alumina as catalyst, (b) reacting the resulting mixed amylenes with benzene at a temperature of 20 DEG C. in the presence of aluminium chloride as catalyst, (c) reacting the resulting mixed amyl benzenes with phthalic anhydride in chlorobenzene at a temperature of 35 DEG C.-40 DEG C. in the presence of aluminium chloride as catalyst and (d) dehydrating the resulting mixed 2-(4-amyl-benzoyl) benzoic acid with fuming sulphuric acid at a temperature of 95 DEG C.

Filed: 1928-02-10
Abstract: 304,054. Levy, S. I., and Gray, G. W. Feb. 10, 1928. Lead and chlorine, obtaining.-Lead is obtained from solutions containing high concentrations of ferrous chloride by electrolysis using an iron anode and an E.M.F. less than that required to decompose the ferrous chloride. The process is applicable to the solutions obtained by treating with hydrochloric acid the product derived from iron pyrites by treating in the absence of air or by treatment with chlorine. An E.M.F. of ¢-1 volt is used. A metal plate is used as cathode on which the lead is deposited in spongy form. By using a higher E.M.F. and a hot solution the lead may be deposited in sheet form. In a modification the lead is separated by means of an iron copper couple obtained by immersing iron filings in copper sulphate solution for a few moments. The weight of filings theoretically necessary is added to a solution of iron and lead chlorides at 50-60‹ C. or other temperature up to boiling point. The deposited lead together with the excess of iron and the small amount of copper remaining is filtered off, washed, pressed and refined. Specifications 307,188, [Class 1 (iii), Oxides &c.

Abstract: 691,765. Mowing machines. WALLEY & CO., Ltd., E. S., and WALLEY. F. G. Feb. 21, 1952 [Feb. 22, 1951], No. 4312/51. Class 6(ii) Relates to machines for simultaneously mowing and picking up grass and like crops comprising ganged mowing units 1 which project the mowings on to a transversely-moving conveyer 2 that carries the mowings away from the units. According to the invention, the mowing units are driven from the power take-off shaft 11 of the tractor to which the machine is hitched at 7. A cutting speed for mowing independent of the travelling speed can thus be provided for. The invention is shown applied to a machine as described in Specification 676,380 in which the power takeoff shaft 11 drives a conveyer having one part travelling transversely to receive the mowings and another part travelling upwards for raising them and depositing them on a second conveyer (not shown) leading to receiving vehicle. In the present invention, the shaft 11 also drives the mowing units through chain gear 13, shaft 16, gear box 17, chain drive sprockets, 27, 26, and universal shaft couplings 29; 30. The machine is supported on three castor wheels 6, and a folding tow-bar 8 permits of hitching the tractor to one side for trailing the machine compactly when transporting.
