Title: Gas discharge display and/or memory devices
IPC: H01J17/49
Filed: 1974-06-21
Abstract: 1479732 Gas discharge display panels; multigap cold-cathode tubes OWENS-ILLINOIS Inc 21 June 1974 [22 June 1973] 27587/74 Heading H1D A gas discharge display and/or memory device comprises first and second conductors 19- 1a and 19-1b having surfaces lying in a common plane, the conductors being closely spaced and isolated from each other; independent respective electrical connections to said first and second conductors; a third conductor 20-1a juxtaposed and spaced from said first and second conductors and co-operating therewith to form first and second discharge sub-sites 18 between said third conductor and each of said first and second conductors respectively, the spacing of said first and second discharge sub-sites being such that a discharge in one of said sub-sites while said sub-sites are subjected to a sustaining voltage causes a discharge in the other subsite; an insulating dielectric layer on the face of at least one of said conductors; and a volume of ionizable gas confined between said conductors, with the dielectric layer bounding the volume of ionizable gas. In the arrangement shown each cell 21 comprises four sub-sites 18 conditions at any one of which influences conditions at the other three sub-sites. It is possible by applying suitable manipulating and sustaining pulses to perform logic and decoding operations inside the panel itself, thus reducing the amount of external circuitry required. Control by inversion logic by interchanging the sustaining voltages imposed on the opposed conductor arrays is also referred to. In one practical construction (Fig. 2, not shown) arrays of pairs of conductors are deposited on two support members and covered by dielectric layers bounding a gas-filled discharge space. In an alternative construction, Fig. 7, a first array of paired conductors 44 is formed on a support member 43 and covered by a dielectric layer 45 on which is formed a second array of paired conductors 49 separated by troughs 47 and covered by a dielectric layer 51 spaced from a glass plate 53 bounding the discharge space. The troughs 47 define the principal discharge region of each cell. In a further alternative embodiment (Figs. 9 and 10, not shown) the troughs 47 are replaced by a cavity at the centre of each cell formed by two crossed pairs of conductors.

Title: Method of producing foundry moulding compositions
IPC: B22C1/20
Filed: 1964-07-06
Abstract: A method of making a water-stable foundry moulding composition comprises a primary stage of converting by acid hydrolysis a silicic ester to silicic acid, a secondary stage of adding an additional ester, which is more readily hydrolysable than the first, to the silicic acid obtained in the primary stage, water in the primary silicic acid serving to hydrolyse the additional ester to form high molecular complex substantially water-insoluble silicic acid, and mixing the said complex silicic acid with a refractory moulding material.  In examples the first ester is ethyl silicate and the second methyl silicate titanic acid ester or orthy-ethyl silicate. Ethyl, butyl isopropyl, or propyl alcohol are added at the primary stage.  Refractories used are zirconium silicate, sillimanite or mulltite.

Abstract: The single-step process of making soap from sperm oil according to the parent Specification which comprises heating a mixture of sperm oil and anhydrous alkali to a temperature of approximately p  270-280 DEG  C. so as simultaneously to saponify the fatty acid esters and to transform the fatty alcohols into fatty acid soap, with agitation in vacuo and continuing the heating under the pressure generated by the liberated gas during the ensuing reaction, is modified in that pre-heated sperm oil and molten anhydrous alkali are used and are continuously supplied to the reaction vessel, the air being removed therefrom by steam pressure.  The heat generated in saponifying the fatty acid esters is used to transform the fatty alcohols into fatty acid soap which is continuously withdrawn from the vessel.  The temperature of the oil entering the reaction vessel is preferably 175 DEG  C. and that of the alkali, between 320 DEG -350 DEG  C.  Raw or refined or partially hydrogenated sperm oil may be used, but substantially completely hydrogenated sperm oil is excluded.

In another arrangement, the plate supports may be secured to the screen and mounted on springs upon the framework 10 ; if desired, the framework may be connected to, and driven by, the frames containing the bars I, II. As shown in Fig. 6, each bar I, II may be provided with an insert 14 of elastic material ; the projections 15 provided on each side of the bar are arranged to gyrate around the projections on adjacent bars. For cleaning purposes, the upper edge of each bar may be of corrugated or serrated form or provided with a brushing device.
