Title: Improvements in sliding clasp fasteners and the like
IPC: A44B19/18
Filed: 1933-02-21
Abstract: 406,129. Sliding clasp fastenings. TCHEKHOVITCH, A., 76, Rue de l'Ouest, Paris. Feb. 21, 1933, No. 5294. Convention date, Nov. 30, 1932. [Class 44.] In a fastening of the type comprising a cord or a band 2 with elements 1 fixed thereon at intervals which engage with beadings 4 on the edges of the parts 3 to be fastened, tilting of the elements is avoided by attaching the band to an external face of the elements substantially in the plane of the beading- receiving apertures 8, the elements for this purpose being notched on one face as shown in the cross-section, Fig. 4, and in addition the circular beading -receiving apertures 8 are extended laterally into comparatively long slots 7. Locking of the fastening is effected by a ball, tassel, or the like 10 which pulls a thickened cord 9 into the apertures 8 of the top element 6 whereby this element is jammed on the beadings. Removal of the elements from the beadings is effected by sliding the abutments 17, which are carried by thin plates 16 at the ends of the beadings, to the position shown in Fig. 1 whereupon the slots 7 of the element apertures can pass over the thin end plates 16. In the open position of the fastening the elements 1 rest directly on one another by being cut out on their top and bottom as shown at 23 in Fig. 12 to accommodate the loopings of the band.

Title: Improvements in or relating to the conversion of distillates obtained from coal and the like into products of lower boiling point
IPC: C10G15/00
Filed: 1932-02-23
Abstract: The yield of products of low boiling-point obtained by distilling mixtures of oils and solid carbonaceous materials, e.g. coal, lignite, shale, &c., is increased by passing the vapours and gases evolved through a silent electric discharge, the voltage of which may vary between 8000 and 100,000, and the periodicity between 100 and 35000 cycles.  The whole of the vapours may be passed through the discharge or part of the vapours may be condensed and the remainder passed through the discharge.  Gases such as hydrogen, methane, or the gases produced in the process may be mixed with the vapours. Coal containing 35 per cent volatiles is ground to a fine powder and mixed with its own weight of heavy oil and the mixture is fed to an inclined rotary retort heated to 400 DEG  C.  The vapours and gases evolved are passed through a silent discharge apparatus operating at 100,000 volts and 35000 cycles and maintained at the temperature and pressure of the retort.  Specifications 104,330, 131,105, 290,606, 294,099, [all in Class 1 (i), Chemical processes &c.], 318,270, [Class 32, Distilling &c.], and 363,360 are referred to.

The lateral position and the angular orientation of the bar 11 may be adjusted relative to the arm 17 in order to control the position at which the top hole can be drilled, the adjustment being effected by the insertion of insert members, e.g. 25 or by a link device 27, 29 or by toothed couplings 43, 47 or members 56, 58 (see Figs. 7, 10, 11). The control of the pivoting movement of the arm may be effected by adjusting the distance between the two pivot of the hydraulic unit, by adjusting the length of stroke of the unit or by the incorporation of external stop bars with adjusting nuts, (see Figs. 20-25). The conveying of hydraulic fluid to the drill unit 13 and the pivoting unit 81 for the operation of the arm may be effected by flexible hose reeled up on the end of the bar 11 which permits the feed and retraction of the drill unit 13 along the carrier bar 11 or alternatively the connections to the various units may he by way of inter-connected pipes formed by rotary sealed devices to permit articulation of the pipes during the movements of the arm and drill unit 13. Similar connections may be made within the support column.

Abstract: 807,079. Electrophotographic processes. GENERAL DYNAMICS CORPORATION. Feb. 21, 1957 [March 19, 1956], No. 5921/57. Class 98(2) An image is formed on an electrically insulating surface by supporting it on an electrically conductive backing material and contacting its surface, either directly or through an intervening layer of insulating liquid, with the surface of a photoconductive layer on an electrically conductive support, forming an electrostatic charge pattern of the image to be reproduced on the surface of the photoconductive layer either before or after contact with the insulating layer, connecting the electrically conductive backing layers so that they are both at the same potential, and then separating the photoconductive and insulating layers and developing the image on the insulating layer. The photoconductive material may be given a uniform electrostatic change followed by imagewise exposure before it is contacted with the insulating layer. Alternatively, the insulating layer may be given a uniform electrostatic charge and the layers assembled in contact. The backing layers are then connected to the same potential and the photoconductive layer exposed through its conducting backing, which must of course be transparent. When the layers are contacted through an intervening layer of insulating liquid, the latter may be a silicone oil, and this may be applied to the photoconductive layer prior to charging. The insulating material on which the image is formed may be a polyester terephthalate plastic film, which may be attached to aluminium foil as a backing. Specifications 672,767, 755,486, and U.S.A. Specification 2,693,416 are referred to.

Abstract: 431,081. Fluid -- pressure brakes. LECLAIR, L. J., BRACKENBURY, A. G., and WESTINGHOUSE BRAKE & SAXBY SIGNAL CO., Ltd., 82, York Road, King's Cross, London. Feb. 23, 1934, No. 6028. [Class 103 (i)] A vacuum brake quick application valve adapted to admit atmospheric air to the train pipe and brake cylinder, comprises a diaphragm 5 subject on one hand to the vacuum in a chamber 2 connected by a port 3 to the train pipe 10, and on the other hand to the vacuum in a chamber 4 connected to the lower chamber of the brake cylinder by a passage 6, by a port 8 to a chamber 7, and by a port 9 to the train pipe and to which atmospheric air is adapted to be admitted by a valve 13 operated by the diaphragm 5. Admission of air to the train pipe on brake application raises the diaphragm 5 as air enters the chamber 2 below the diaphragm through the port 3 more quickly than it enters the chamber 4 above the diaphragm through ports 8, 9 and the chamber 7. Air is admitted to the brake cylinder through the port 8 and to the train pipe through the port 9. The pressure finally balances on each side of the diaphragm which falls, closing the valve 13. Air now passes from the train pipe to the brake cylinder by ports 9, 8. In order to give an initial rapid flow through the port 9 this port is replaced by a large and a small port, the large port being eventually closed by a valve operated by the pressure in the conduit 10 opposed to atmospheric pressure, or a valve closing the large port is first opened by atmospheric air admitted to the chamber 7 and subsequently closed when the pressure in the train pipe has risen. The diaphragm 5 may be arranged to engage a depending flange surrounding the port 8 and thus close this port, so that at the head of the train where the rise of pressure in the train pipe is rapid the diaphragm will rise sufficiently to close this port and restrict the flow, and at the rear of the train where the rise of pressure is slower the flow will not be so restricted.
