Patent GB-226830-A (GB)
Abstract: 226,830. Compagnie Internationale des Freins Automatiques Soc. Anon., (Assignees of Pieper, H.). Dec. 29, 1923, [Convention date]. Preventing stopping of engine when actuating auxiliary suction apparatus.- In direct-acting fluidpressure brakes, or brakes a p p 1 i e d mechanically, as by weights, wherein the actuating - mea.ns is restored, in the one case to its original pressure, and in the other to its initial position each time the brakes are released, release is effected by means of a partial vacuum. An arrangement utilizing the suction of an internal-combustion engine for the purpose is shown in Fig. 1. When the valve 34 is opened by the brake lever 36 pressure fluid from the chamber 35 enters the cylinder 6 and drives out the piston 5 to apply the brakes Release is effected by rotating the lever to connect the chamber 3 through the valve 37 to the induction pipe 1 of the engine, the partial vacuum thereby created causing the diaphragm 4 to rise, whereby the fluid in the cylinder 6 is returned to its reservoir, the valve 34 being free to rise. On the completion of the release movement, the engagement of the diaphragm disc 41 with a rod 42 raises a valve 43 to cut off the chamber 3 from the pipe 1 and connect it to atmosphere at 44, so that no delay will occur in a subsequent brake application. By using a valve 37 adapted to connect the chamber 3 either to the pipe 1 or to atmosphere, the valve 43 may be dispensed with. A supplementary fuel-supply nozzle 39 is provided on the pipe 2, in order that the composition of the combustible mixture may not be altered during exhaustion of the chamber 3.

Abstract: 720,085. Coin-freed apparatus. COXE, A. D. H. Sept. 12, 1951, [Sept. 18, 1950], No. 22907/50. Class 27. [Also in Group XV] A peep show comprises at least two pictures only one of which is normally visible to a viewer, the pictures being arranged for viewing according to the Pepper's Ghost illusion, and means within the peep show box for actuating the Pepper's Ghost mechanism, which means is operable by air under pressure supplied by the viewer, whereby the viewer selects an alternative picture to be seen. A coin-freed peep show comprises three pictures 15, 17, 19 of which 17 and 19 are selected in turn by the user blowing into a passage 5. Inward movement of a coin slide 22 actuates a time clock 24 which cuts in current supply to lamps 14. The picture 15 is thus illuminated, reflected from plate glass screen 20 and seen through plate glass screen 21. Withdrawing the slide 22 to normal position causes a pawl and ratchet 25, 26 to actuate a sound reproducer 27 which after a predetermined interval instructs the viewer to blow. A shutter 6 is thus pivoted upwardly, and through gearing 8, 9, causes a switch 10 to switch off lamps 14 and to switch on lamps 16, picture 17 thus being seen. The shutter, after the viewer has ceased to blow, is allowed to return to normal position through the provision of a slipping clutch arrangement. For changing the picture seen from 17 to 19 shutter 6 is again actuated and after a further interval, the time clock finally cuts out all illumination and the machine is ready for a further operation. The shutter may also release compressed air which bubbles through a transparent water tank viewed in conjunction with the pictures and a number of shutters may be embodied to produce a gradual change from one scene to another. A hand controlled mechanism may produce the air draught to operate the shutter. According to the Provisional Specification, the sound mechanism may supply music.

Abstract: 1,126,849. Microporous olefin polymers. W. R. GRACE & CO. 19 May, 1967 [19 May, 1966], No. 23338/67. Addition to 1,051,320. Headings C3C and C3P. A process for making shaped articles of microporous cross-linked olefin polymers comprises forming a homogeneous mixture of a solid polyethylene, polypropylene or ethylene/vinyl copolymer and 20-400% (on the weight of polymer) of a pore-forming solid of particle diameter 0À1-10 microns, shaping the mixture at a temperature between the m.pt. of the polymer and the gelling pt. of the mixture, cross-linking the olefin polymer, removing the pore-forming solid and, necessarily when the polymer is ethylene, optionally when it is polypropylene or an ethylene/vinyl copolymer, orienting the shaped article. The cross-linking may be achieved by either generating freeradicals in situ, e.g. by heating 1,4-bis-(t-butylperoxyisopropyl) benzene, or by submitting the article to ionizing radiation. The orientation may be uniaxial or, preferably, biaxial and may be achieved by stretching the material at a temperature not more than 10‹ C. below the m.pt. of the polymer and under reduced pressure. The pore-forming solids preferred are sodium chloride, sodium carbonate, sodium benzoate, sodium acetate, silica gel, starch, benzoic acid, hydroquinone, dimethylterephthalate, anthracene, but cane-sugar is the most preferable. In the examples articles of polyethylene, polypropylene, ethylene-propylene, ethylene-vinyl acetate and ethylene-ethyl acrylate copolymers are produced.
