Abstract: 802,886. Turf piercing machines, lawn mowers. LOUIS, R. G. July 25, 1957 [July 30, 1956], No. 23612/57. Classes 6(1) and 6(2). A machine for spiking lawns for attachment to a vehicle such as a lawn mower comprises a plurality of upright elements 15 slidably arranged in a frame structure 10 and adjustably attached to a cross-bar 17 movable in slots 16 in the frame 10 and reciprocated by means of crank pins 24 and connecting rods 18. The crank pins 24 are mounted on discs 25 driven by chain gearing 29 from a roller 4 of the lawnmower. The elements 15 may be provided with ends 31 of inverted conical shape or of chisel shape. The ends may be ragged to lift soil and roots. The frame 10 is fitted with slides 19 which engage guide bars 20 fixed to the mower, tension springs 21 being fixed between the slides 19 and bars 20 to draw the slides towards stops 23. When the elements are engaged in the ground the frame is moved rearwardly against the springs 21 until the elements are withdrawn from the ground. A cutter may be attached across the lower ends of the elements to cut clods. In a modification the frame may be pivoted about a horizontal axis, instead of being slidable in guide rods 20, spring means being provided to retain the frame in a vertical position but permitting rearward tilting of the lower end of the frame.

Abstract: 1,016,083. Duplicating machines. ZEPHON Ltd., and E. V. BYERS. July 13, 1964 [June 18, 1963], No. 24123/63. Heading B6C. [Also in Division F2] A duplicating machine comprises a smoothsurfaced roller 1 and a flexible roller 6 of smaller diameter, disposed beneath the roller 1, the roller 6 being pressed towards the roller 1 by a number of spaced members 7 urged upwardly by a spring or springs. A master sheet, copy sheet and flat flexible platen are traversed between the rollers 1, 6 by rotating the roller 1 by means of a handle. As described, two strip springs 9 are employed, each engaging shoulders at the sides of the members 7 and resting on intermediate supports 10 which cause them to assume a sinuous shape. The members 7 are of anti-friction material such as acetal resin and their bearing surfaces are substantially semicircular. Upward movement of the members 7 and therefore of the roller 6 may be limited so that there may be a small gap between the rollers 1, 6, and for this purpose the upper edges of a trough 5 enclosing the devices may be bent inwardly to form stops, or the members 7 may pass through the bottom of the trough and have side extensions engaging the outside of the trough bottom. Flexible connections 12 prevent the members 7 from moving laterally. The roller 6 may be made of nylon.

Abstract: 1,260,901. Measuring the duration of a light pulse. COMPAGNIE GENERALE D'ELECTRICITE May 13, 1969 [May 31, 1968], No.24443/69. Heading G1A. In an arrangement for measuring the duration of a very short light pulse the pulse 305 is split into two pulses 306, 307 each is applied to an optical delay line 308, 309 to produce a series of pulses of different repetition frequency, and the pulses of the two series are combined and supplied to a detector 313, the detector output signal being a function of the varying pulse overlap and thus an indication of the pulse width. Pairs of optical delay lines in which the delay in one is adjustable are described with reference to Figs.4-8 (not shown) and each delay line may comprise a reflecting mirror and a parallel halfsilvered mirror into which a light pulse is introduced at a slight angle to the normal to produce a chain of pulses, and in the adjustable line, the distance between the two mirrors may be adjusted in steps by for example a micrometer, steps being necessary to prevent the development of fringes. Other arrangements for achieving different delay times may be chambers filled with gases at different pressures or a low-loss birofringent crystal the outside of which is lightly silvered.

Patent GB-882768-A (GB)
Title: Novel vitamin-a esters and a process for the manufacture thereof
IPC: C07C403/00
Filed: 1960-07-15
Abstract: The invention comprises substituted-benzoic acid esters of Vitamin-A in which the substitution consists of one or two amino groups which may be alkylated or acylated.  Specified compounds are Vitamin-A p-amino-benzoate, and the corresponding m-amino, o-amino, 3,5-diamino, p-dimethylamino, and p acetamino-derivatives.  These compounds may be made by esterifying Vitamin-A or a derivative such as Vitamin-A alcohol or Vitamin A-acetate with a benzoic acid, or a reactive functional derivative thereof, carrying one or two amino groups, which may be alkylated or acylated, or one or two radicals which may be transformed into amino groups, transforming the said radicals (if present) into amino groups and, if desired, acylating any amino group or groups present.  In the case of alkylated and acylated amino-benzoic acid compounds the substituents on the amino groups are preferably lower alkyl radicals such as methyl or ethyl radicals, and acyl radicals derived from lower alkanoic acids such as acetyl radicals, or aromatic carboxylic acid radicals such as benzoyl. In a typical Example (No. 1), Vitamin A alcohol was added to a solution of p-nitro-benzoyl chloride in absolute pyridine in an atmosphere of nitrogen and allowed to stand to produce Vitamin-A p-nitro-benzoate which was subsequently dissolved in alcohol and toluene and reduced in the presence of hydrogen and nickel to produce Vitamin-A p-amino benzoate.

Title: Improvements in or relating to the purification of naphthalene
Inventor: GOLDING WILLIAM ERNEST
IPC: C07C7/00
Filed: 1950-10-10
Abstract: Naphthalene is purified by contacting with an aqueous liquid containing a wetting agent to remove non-aqueous liquid contaminant. It may first be contacted with a solvent for the liquid contaminant, e.g. a petroleum fraction such as kerosene, gas oil or white oil for removing creosote oil.  The washing operations may be effected by passing the washing liquid through a layer of the naphthalene, by stirring the naphthalene in the liquid, by blowing air through the mixture or by spraying the naphthalene while being whizzed. Preferably, violent agitation is avoided to prevent emulsification so that the solution of wetting agent can be reused.  The wetting agent may be a salt of a higher alkyl sulphate, e.g. "Teepol" or "Comprox," or of the polyethylene glycol type, e.g. "Lissapol" N, all being Registered Trade Marks.  In examples, 0.5 per cent aqueous solutions of wetting agent are used, with or without prior treatment with kerosene.  The naphthalene may then be water-washed, drained and dried.

Abstract: 371,269. Spiral springs. BROEK, J. A. VAN DEN, 715, South Forest, Ann Arbor, Michigan, U.S.A. Sept. 7, 1931, No. 25036. [Class 108 (iii).] A flat spiral spring is coiled in such a way as to avoid the tendency of the coils to make contact at one side, the outer end being guided so that it is always tangential or at right-angles to a radius to the centre and is also free to adjust itself in the direction of the radius. In the construction shown in Fig. 4, the outer end A is fixed to a bar B which bears upon pins C, D and is free to move endwise. When this spring is tensioned by rotating its inner end, the outer end may move closer to the centre but cannot move in any other way. The outer ends of the two opposed springs shown in Fig. 2 are rigidly connected to a bar B. When the springs are wound up at their centres, the bar moves parallel to itself towards the centre. In a modification two springs with coaxial centres have their outer ends connected.
