Patent GB-1020282-A (GB)
Title: Reactive selectively sorptive silica materials and process for producing them
IPC: B01J20/10
Filed: 1962-10-01
Abstract: Organic silicon compounds are obtained by the reaction of primary and secondary alcohols, e.g. butanol, decanol or octadecanol, at 200 -240 DEG  C. under pressure with a silica material consisting of discrete hexagonal phylloidal particles containing by weight 75-92% SiO2, at least 5% H2O and less than 15% other oxides, said particles having a characteristic thickness of 0.003 to 0.020 microns, facial dimensions of 0.1 to 5 microns and a B.E.T. surface area of 300-500 m.2 per gram. at least 60% of their surface area being constituted by porosity in the particles.  The products retain the leaf-like characteristic of the silica while being predominantly, e.g. 90%, esterified.ALSO:Silica material consisting of discrete hexagonal phylloidal particles containing 75-92% SiO2, at least 5% H2O, and less than 15% of other oxides based on dry weight at 105 DEG  C., the particles having a thickness of 0.003-0.020 m , a facial "diameter" of 0.1-5 m , a B.E.T. surface area of 300-500 m.2 per gram and containing at least 60% of their surface area constituted as porosity, is claimed as a new product per se. A process for producing such material comprises forming an aqueous suspension of anhydrous aluminium silicate, the latter being produced by heating finely divided kaolin predominantly of less than 10 m  at a temperature of 500-925 DEG  C., adding to the suspension a strong mineral acid e.g. sulphuric acid which will form a soluble aluminium salt in an amount exceeding 90% of that which is stoichiometric to the alumina content of said silicate and thus bringing the liquid medium to an acid concentration from 20 to 50% by weight, allowing the acidified suspension to boil, digesting the reaction mass at 90-105 DEG  C. at an acid concentration of 15-50% until 80% of the metal oxide content of the suspended particles is extracted, and then separating the reaction liquid from, and washing and drying, the resulting solid particles.  The anhydrous silica material is formed if desired by heating e.g. to 900 DEG  C. The Specification also discloses the use of the silica product in preparing alkali metal, particularly sodium, silicates, alkaline earth metal, particularly calcium barium or magnesium, silicates and zinc or lead silicate from the corresponding metal oxides.
Patent GB-1040595-A (GB)
Title: Decimal-digital limit-value switching arrangement
IPC: G07C3/14
Filed: 1963-09-24
Abstract: 1,040,595. Decimal limit-value detectors. FARBENFABRIKEN BAYER A.G. Sept. 24, 1963 [Sept. 26, 1962], No. 37556/63. Heading G4M. A decimal limit-value detector consists of a ten-position switch for each decade the contacts of each switch being interconnected by diodes and there being two contacts selected for each limit setting, except in the lowest decade, one or the other being operative according to the comparison in the next lower decade. The input value is represented by the positions of the wipers of three selector switches which are connected via diodes D1, D2 and D3, Fig. 1 (not shown), to a negative source. The switch contacts are interconnected by diodes B0-B8 so that current can flow from lower to higher contacts only. Selected output terminals are connected to relays A-F, relays A, B and C relating to the upper limit and relays D, E and F to the lower limit. In the case shown the upper limit is set at 463 and the lower limit at 448. The value entered is 456. The operation of upper limit detection is as follows: Since the unit value 6 is higher than the upper limit unit digit 3 no current can flow to relay C because of the diodes between contacts 6 and 30 so that relay C remains unoperated. The tens value 5 is below the upper limit tens digit 6 so that current can flow through contact 5 and diode D6 to relay B. The hundreds value is 4 and the corresponding upper limit digit are the same so that no current can flow through to relay A from contact 4 to contact 3 (prevented by the interconnecting diode) and via diode D4. But since relay B has operated carry contact b is closed and current flows to relay A through contact 4 and contact b. The final result is that relays A and B are operated and relay C is not. The operation of relay A indicates that the value 456 is below the upper limit. If the hundreds value had been 5 or above the A relay could not operate, indicating that the upper limit had been exceeded. The operation of lower limit detection is similar, relay F being operated by the lower units value 6 and relays E and D both remain unoperated. In a modification the diodes interconnecting the switch contacts may be poled in the opposite direction to pass current from higher to lower contacts. The connections to the relays A, B, D and E are via two way contacts controlled by relays of the lower decades and the diodes D4-D7 are omitted. Relays may be replaced by gating circuits.

Abstract: 907,822. Friction clutches; clutch control. FRANCAISE DU FERODO S.A. Nov. 21, 1958 [Nov. 23, 1957; July 9, 1958], No. 37631/58. Class 80 (2). In a motor vehicle centrifugal clutch of the Gravina type (Specification 586,910) wherein at least one driven friction plate 13 is clamped against an engine flywheel 12 by a presser plate 14 acted on, against separating springs 9, through pre-stressed transfer springs 15, transfer plate 16, thrust bearing 17 and a cam-plate 18, by rollers 19 of centrifugal masses 20 pivoted on an axially-fixed carrier 22 which is held stationary for clutch disengagement by energizing a stationary electromagnet 28 to hold a clutch-brake disc 26 resiliently connected to the mass carrier 22, and clutched to the flywheel, for centrifugal clutch engagement, by deenergizing the magnet 28 to permit springs 26<SP>1</SP> to clutch the disc 26 to the flywheel at 27, the masses are divided into two groups: one in which centrifugal displacement of the masses is retarded by prestressed torsion springs 29, and the other in which the masses are freely pivoted, the freely pivoted masses acting alone to effect initial clutch engagement when the flywheel reaches a picking-up speed. The transfer springs 15 limit the load on the friction elements and are not deformed during the slip period. The flywheel cover 24, the carrier 22 and the transfer plate 16 may be constructed to have a predetermined resiliency. The driven plate may be rigid as shown or of the axially compressible type. The energization of the electromagnet 28 may be dependent on the gear-changing operations. Continuous drag means to take up play may comprise a spring-pressed cone 33 (as shown) or thrust washer (Fig. 4, not shown). The Specification includes graphs in respect of torque/speed and clutch load/cam axial movement. Details are also provided in respect of the stiffness and pro-stressing of springs; lining wear; the resilience of the cover 24, the carrier 22, and the transfer plate 16; and the geometrical characteristics of the masses 20, the carrier 22 and the cam 18.

Abstract: 914,195. Storing liquefied gases. SOHDA, Y., and SOHDA, Y. Nov. 4, 1960 [Nov. 4, 1959; Dec. 3, 1959], No. 38076/60. Class 8(2). In a container vessel assembly for the storage and transportation of liquefied gases the vessel is provided with injection means for injecting into the interior thereof both gaseous nitrogen pre-cooled to a temperature between.-17.0 ‹0. and-180‹C. and liquefied nitrogen, in the form of finely dispersed bubbles and liquid particles, whereby both the gaseous and liquefied nitrogen are brought into intimate heat exchange with a body of liquefied gas contained in the vessel for effective cooling thereof. As described with reference to Fig. 1 a container vessel 1 is substantially filled with liquefied natural gas a, the vessel having a pipe 2 for inlet and outlet of the gas. Liquefied nitrogen and gaseous nitrogen from reservoirs 9 and 7, respectively, are injected into the vessel through pipes 8 and 6 and parallel spiral coils 5 and 4, the latter having orifices therein arranged so as to inject the nitrogen gas and liquid towards each other, and towards the wall of the vessel. A fractionating chamber 13 is provided at the top of the vessel to which is connected the suction pipe 14 of a multistage refrigerant compressor 15 having a delivery pipe 18 connected to the liquefied nitrogen reservoir 9 and a delivery pipe 19 through which gaseous nitrogen is tapped from an intermediate stage of the compressor and led to the reservoir 7. The pipe 19 may be provided with a cooler and an expansion valve. Liquefied nitrogen may be supplied from the reservoir 9 through a pipe 21 to the reservoir 7 and through a pipe 23 to the fractionating chamber 13. Any natural gas reliquefied in the compressor 15 is returned to the vessel 1 through a pipe 24. The fractionating chamber 13 may be dispensed with. The spiral coils 5 and 4 may have a diminishing diameter or a course pitch as they approach the centre of the vessel; they may be replaced by a plurality of concentric coil elements or the coil for the liquefied nitrogen may be disposed within the coil for the gaseous nitrogen, the coils having concentric injecting nozzles, Figs 4 to 8 (not shown). A plurality of coil assemblies may be spaced one above the other in the vessel, Figs. 9 and 12 (not shown). The return pipe 24 may be connected to a separate vessel instead of to the vessel 1. Nets may be provided above the orifices or nozzles on the coils so as to finely disperse the nitrogen and a further net may be disposed just below the surface of the liquefied natural gas a to collect any solidified flakes of the latter so as to bring them into heat exchange contact with the rest of the natural gas. The container vessel may have a double bottom, gaseous nitrogen being supplied to the space between the bottoms for heat insulation; the inner bottom may have a plurality of fine openings preferably along its periphery so that the gaseous nitrogen can pass into the interior of the vessel.
