Title: Improvements in or relating to electrical safety switching devices for vehicles
IPC: H01H29/22
Filed: 1933-04-22
Abstract: 418,232. Mercury switches. HOWARD, G. W. R., Bassett, Pyrford, Woking, Surrey, and DUNN, P. W., 78, Cornwall Road, Bayswater, London. April 22, 1933, Nos. 11814/33 and 7583/34. [Class 38 (v).] A safety switch for vehicles or aircraft operable on collision or overturning comprises a cup-shaped receptacle 10 containing mercury which normally bridges contacts 12 in the electrical system. Surrounding the cup is a member 15 forming an outer receptacle which is fitted with a cover 18 having a deflector part 21 projecting into the cup 10 and leaving an annular passage from the cup to the outer receptacle. The cover is formed with a chamber 19 which communicates with the outer receptacle by means of a duct 20. Shoulders 14 prevent the mercury from splashing out of the cup but, on overturning or collision, the mercury passes into the outer receptacle 18 and into the chamber 19. A shoulder 16 prevents automatic resetting when the vehicle is righted. Resetting is accomplished by unscrewing the members 15 and 18 together and pouring the mercury through the duct 20 into the chamber 19. The cover is then removed and the mercury poured back into the cup 10. A third contact 22 in the cup 10 may be used as an earth connection. The switch may be pivotally mounted on a bracket by means of the terminals 12. In a modification a manually operated valve is provided between the chamber 19 and cup 10 to facilitate resetting without unscrewing the cover.

Title: Improvements in and relating to the stretching of plastic net for molecular orientation of the mesh strands
Inventor: MERCER FRANK BRIAN
IPC: B29C48/05
Filed: 1960-04-04
Abstract: 905,252. Finishing fabrics; netted fabrics. PLASTIC TEXTILE ACCESSORIES Ltd. March 21, 1961 [April 4, 1960], No. 11835/60. Classes 42 (1) and 74 (1). The net strands of an extruded plastic net are molecularly orientated but the net intersections left substantially unstretched by stretching the net in a direction transverse to the lengthwise extent of the net as considered in its direction of extrusion. The net is stretched by the machine shown in Fig. 1 after the plastic has been fixed or set. The margins of a longitudinally slit tubular net fed from a reel 1 are gripped by stenter clips on endless chains 2, 3 which extend parallel to each other in a zone A, preferably a pre-heating zone, and diverge in a zone B. At the end of zone B fixed or rotary knives 9 sever the margins engaged by the clips, the severed edges being deposited as waste on opening of the clips before they re-enter the zone A. The net passes to driven, pressure rolls 7, preferably warmed to flatten the net intersections i, Fig. 2. If the net to be stretched has diamond-shaped meshes with diagonal lying longitudinally of the net, the stretching elongates the meshes in the direction of the other diagonal so that the strands s lie generally parallel to each other, perpendicular to the net length and linked by thicker intersections at rightangles thereto. A flattened, unslit tubular net may be stretched by the machine of Fig. 1. Specification 836,555 is referred to.

Patent GB-712300-A (GB)
Title: Improvements in or relating to the preparation of alcohols
Filed: 1952-05-15
Abstract: Alcohols are obtained by reduction of the corresponding esters with sodium or potassium borohydride mixed with an equivalent quantity of a lithium salt, especially the chloride, in an inert solvent. Unsaturated linkages in the esters are sometimes hydrogenated at the same time.  In examples, benzyl alcohol, n-octadecanol, propyl-b -(a -tetrahydrofuryl) alcohol, undecylenic alcohol, and p-nitrobenzyl alcohol are obtained by reducing the ethyl esters of the corresponding acids with potassium borohydride and lithium chloride, in various solvents; ethyl cinnamate gives a large quantity of hydrocinnamic alcohol under the same conditions.  Other lithium compounds which may be used are the bromide, iodide, sulphate and nitrate; other lithium salts are less active.

Title: Improvements in or relating to electric wave guides
IPC: H01P1/06
Filed: 1942-09-01
Abstract: 595,352. Wave-guides. CORK, E. C., and MANIFOLD, M. BOWMAN-. Sept. 1, 1942, No. 12349. [Class 40(v)] Leakage at a gap in a wave-guide where two sections are mounted for relative rotational movement is prevented by providing flanges or overlapping surfaces at the gap of such dimensions as to provide a short circuit for waves travelling along the guide, but to form a blocking circuit for waves emerging through the gap. As shown in Fig. 1, the fixed guide 7 and the rotary guide 6 are each provided with a flange 8, 9, the radial length of which is a quarter wavelength, the flanges being slightly spaced from each other. The flanges may be an odd number of quarter-waves in radial length, and the gap between them may be widened for the intermediate quarter wavelengths so as to produce reflections by their different characteristic impedances and so reduce the leakage still further (Fig. 3, not shown). The gap may be of labyrinth form, Fig. 2, the sections X having a larger gap width than the sections Y. Instead of flanging the guides, one may be enlarged in diameter for a quarter-wave of its length and may enclose the other so that the gap is of cylindrical form. The rotatable portion 12, Fig. 5, of the guide may have a wave-radiating slot 13 situated at the focus of a parabolic reflector 14 which rotates with the guide. A second reflector 17 and slotted wave-guide 15 may be rotated jointly with the first and may transfer received energy to a stationary wave-guide 19 leading to the receiver.
