Title: Improvements in or relating to the manufacture of sliding clasp fasteners
IPC: A44B19/46
Filed: 1933-05-01
Abstract: 418,901. Sliding clasp fastenings. CHAPPUIS, J. A., 4, Rue de la Gare, Peseux Neuchatel, Switzerland, and LIGHTNING FASTENERS, Ltd., Imperial Chemical House, Millbank, London. May 1, 1933, No. 12691. [Class 44.] For clamping the elements of a sliding- clasp fastener on a stringer tape a series of elements are arranged in close pack formation so that they are in face contact with each other with the interlocking projection of one element entering the recess of the adjacent element and while thus rigidly held the first or a number of alternate elements are clamped on the tape ; in the latter case the intermediate elements are subsequently removed by flexing the stringer. The pack of elements 16 is pressed against a pair of stop members 8, 9 and after the legs of one or more elements have been bent on the stringer tape 12 by the clamping tools 10, 11 the tape is fed forward by the gripper arms 14, 15. During the clamping action the stops 8, 9 slightly close so as to grip the previously clamped element and thus the tape is firmly held. A stationary guide (not shown) is placed above the pack to ensure the seating of the elements on the tape. Specifications 418,904 and 418,905 are referred to.

Abstract: 680,157. Preventing condensation on windows. DAIMLER-BENZ AKT.-GES. May 22, 1950 [May 20, 1949], No. 12698/50. Class 20(iii) The side windows, and preferably also the front and rear windows, of a vehicle are defrosted by directing onto them air which has preferably been warmed and drawn from the exterior of the vehicle. Air, which may be heated electrically, or by the vehicle radiator, enters a duct 4, which may be a branch of the car heating system, and is distributed by pipes 6, 8, and 10 to nozzles 7, 9, and 11 to supply air to the front, side, and rear windows of the vehicle respectively. Stop-cocks 12, 13, and 14, or a common valve system located in a distributor box 5, control the supply of air to each nozzle. Each nozzle 9, provided with vanes 17 for equal distribution of air from an opening along its side, is fixed on a corner post, or on the dash-board, at each side of the vehicle, a nozzle 11 having a horizontal opening being fixed beneath the rear window pane. A nozzle 11 may be used in the side pane position when sufficient room is available to mount it with its opening extending parallel to the side of the respective side pane at the front of the vehicle.

Title: Method of controlling the electromagnetically-driven engraving element of an engraving machine
Inventor: VOS FERDINAND ALLARD DE
IPC: B44B1/00
Filed: 1969-03-11
Abstract: 1278122 Engraving WERKSPOOR-AMSTERDAM NV 11 March 1969 [26 March 1968] 12831/69 Heading H4F  The depth of penetration of an electromagnetically driven engraving element into the engraving material is determined by generating an alternating current and also a direct current and controlling the electromagnetic driving system therewith, the amplitude of the alternating current and the magnitude of the direct current both being determined in dependence on the measured grey value of an original which is being copied. Preferably the sum of the magnitude of the D.C. and the amplitude of the A.C. is constant as the grey value varies and is such that the driving system is substantially saturated. Thus in Fig. 1, the mechanical zero position of the element at rest is at 2, below the surface 1 of the engraving material. For a black tone, the current is mainly A.C. and the element moves about line 2 in a sine curve 3, while for a white tone the current is mainly D.C. and the element follows line 6. For a grey tone a sine curve 4 about a line 5 is followed. The maximum amplitude of the A.C. gives a displacement substantially equal to the distance between line 2 and surface 1. Preferably the frequency of the A.C. is greater than the resonant frequency f 0  of the engraving element, and equal to where # is the damping factor of the vibrating system. Since there is a 180 degree phase difference between the A.C. and the displacement of the engraving element when operated above resonance, current pulses are supplied at required times to provide the required discontinuity in current e.g. when going from black to white and vice versa, Fig. 4 (not shown).

Title: Improvements in or relating to the chlorination of polymerised olefins
IPC: C08F8/20
Filed: 1940-08-14
Abstract: 559,294. Chlorinated polypropylene. STANDARD OIL DEVELOPMENT CO. Aug. 14, 1940, No. 12995. Convention date, Oct. 7, 1939. [Class 2 (iii)] Solid, thermoplastic products are obtained by chlorinating polypropylene, or propylene-. containing polymers derived from a refinery C3 cut, dissolved in a chlorine-resistant solvent, e.g. carbon tetrachloride. Uniformly chlorinated products are obtained by maintaining the solution at a predetermined temperature and introducing chlorine at a predetermined pressure until substantially no further chlorine is absorbed. The polymer may be chlorinated in admixture with natural rubber or polyisobutylene or other olefinic polymers. The chlorinated product is soluble in aromatic hydrocarbons, varnish and lacquer oils and solvents, and is compatible with chlorinated polyisobutylene, rubber, chlorinated rubber and chlorinated hydrogenated rubber. In an example, a propylene polymer, dissolved in carbon tetrachloride, is treated with chlorine for 2¢ hours at atmospheric pressure and at a temperature of 50-60 C. to yield a product having a chlorine content of 59 per cent. Specifications 511,418 and 539,416 are referred to.

Title: Improvements in and relating to the conversion of hydrocarbon oils into lighter oils
Filed: 1927-09-22
Abstract: 299,683. Arnold, C., (Standard Development Co.). Sept. 22, 1927. Divided on 302,415. Right to Patent relinquished. Hydrocarbons, cracking.-In liquid phase cracking processes of the tube and digestion drum type in which pairs of digestion drums are employed so that one may be used while another is being cleaned, the drum which has just been cleaned is filled with heated oil before diverting the stream of oil passing to the drum still in use. The plant comprises duplicate cracking coils 2, 2<a> from which the oil flows either to digestion drums 7, 11 or to duplicate drums 7<a>. 11<a>. Normally oil is passed from both sets of coils 2, 2<a> to one set of drums. If the drums 7, 11 are in use, the cleaned drums 7<a>, 11<a> are preheated and partially filled with oil by gradually closing valve 18 and opening valve 35<a>. The drums 7<a>, 11<a> are thus partially filled with some of the oil from the coil 2<a> and are then filled completely by injecting high pressure steam into drum 11 through a line 37 thus forcing the oil in the drums 7, 11 through the manifold 5 into the drums 7<a>, 11<a>. Alternatively the drums 7<a>, 11<a> can be completely filled from the coil 2<a>, the contents of the drums 7, 11 being discharged through tar lines 29a, 30<a>. The cracked products pass through a reducing valve R to a dephlegmator 17 the temperature of which is controlled by the crude oil passing through a coiled pipe 21. Specification 286,917 is referred to.

Abstract: 131,667. Schermuly, A. W. L. July 24, 1918. Hooks, slip, for suspending and releasing ships' boats and for analogous purposes are so arranged as to remain in position without the aid of catches. The end of the boat is provided with a fixed hook A, and the after end with a lever hook c pivoted at b between two plates B. The suspending tackle ends D are connected by a tierope E, and are attached to the hooks A, c by links d<2>.

Actuated or applied by running wheel or axle and driving-mechanism disengagers; periodic.-In means for stopping machines with the parts in a predetermined position, the release of a latch 29 preferably by the clutch-disengaging means causes a spring acting through a link 24 tu engage a strut or link 21 with the inclined surface 22 of a resilient member 11 fixed to the bed-plate 12 at 14, thereby tending to raise an arm 19 fast on a rock shaft into contact with a cam member 4 fast on the driving-shaft 2, such contact being prevented except at a predetermined point in the revolution by the engagement of a pin 31 on an arm 30 fast on the rock shaft 8 with the edge of a cylindrical member 32 fast on the shaft 2. When, however, a recess 34 in the member 32 comes opposite the pin 31, the upward movement of arm 19 is completed, and it is then depressed by the cam surface 23, thereby applying the brake 7 to the drum 6 through the strut 21, member 11, link 9, and spring 16. The pin 31 is a spring pin and is forced inwards into its socket by the inclined wall of the recess 34 after it has entered this recess so as to permit the further rotation of the parts.
