Title: Process for the extraction of alkali hydroxides and/or carbonates and of alumina from alkali metal and aluminium silicates
Filed: 1937-06-14
Abstract: In a process for extracting alkali metal hydroxides or carbonates together with alumina from alkali aluminium silicates such as leucite or feldspar by thermal reaction of the silicate with an alkaline-earth metal oxide, hydroxide, or carbonate such as lime or limestone, a fluoride such as fluorspar is added to the charge, whereby reaction occurs below the melting point of the mixture, say at 900 to 930 DEG  C.  The calcined mixture after cooling is powdered and lixiviated with water to extract alkali aluminate, from which in the known manner by the action of carbon dioxide alumina and an alkali carbonate solution may be prepared, the latter being converted to caustic alkali if desired.  The residue from the lixiviation, comprising silicates, silicofluorides, and silicoaluminates of the alkaline-earths, may be used for the production of cement.  The Specification as open to inspection under Sect. 91 comprises also the addition to the residue, before calcining it to form cement, of 3-5 per cent of ferric oxide.  This subject-matter does not appear in the Specification as accepted.ALSO:The residue obtained by lixiviating a sintered mixture of alkali aluminium silicate, an alkaline-earth, and a fluoride, comprising silicates, silicofluorides, and silico-aluminates of the alkaline-earths, is used for the production of cement.

Title: Stabilized polyalkylene oxides and process for preparing them
IPC: C08K5/00
Filed: 1965-04-20
Abstract: Polyalkylene oxides are stabilized by a mixture of the following compounds: (a) a compound of the formula <FORM:1087567/C3/1> (b) a compound of the formula <FORM:1087567/C3/2> and (c) a compound of formula R4SnR5, wher R is alkyl, aryl, or heterocyclic, R1 is alkyl, aralkyl, cycloalkyl, aryl, or heterocyclic, A is S or CH2, R2, R3 are alkyl of 1 to 4 carbon atoms, n is 1 to 4, and R4, R5 are alkyl or -(CH2)m-COOR6, where R6 is an alkyl and m is 1 to 4. Suitable polyalkylene oxides are those obtained by polymerizing saturated alkylene oxides, halo-substituted epoxides, e.g. epichlorohydrin, cycloaliphatic epoxides, or epoxy ethers, e.g. methyl glycidyl ether, or by copolymerizing saturated with unsaturated epoxides e.g. glycidyl acrylate.  Typical examples of compounds (b) are bis(4-hydroxy-2-methyl-5-t.-butyl-phenyl) methane and bis(4-hydroxy-2, 5-di - t. - butyl-phenyl)sulphide.  Typical examples of compounds (c) are di(octadecyl)sulphide, di-(dodecyl) tetrasulphide, and tetrasulphide (diacetic acid octadecyl ester). The stabilizer may be added as a solid or in solution.  The stabilized polymers may be dissolved or caused to swell, and may be cross-linked.  Swelling agents or solvents are dimethyl formamide, tetramethylene sulphone, dioxane, methanol, aromatic hydrocarbons and chlorinated hydrocarbons. Soots, fillers, dyes or pigments, extender oils or lubricants may also be added.  The example describes the stabilization of a methanolic solution of 100 parts of a mixture of propylene oxide-allyl glycidyl ether copolymer, thiourea, silicic acid, zinc oxide, dipentamethylene thiuram-tetrasulphide, 2-mercaptobenzothiazole and titanium dioxide with a mixture of 2 parts of each of three compounds of Formula (a) in which R is methyl and R1 is 3-ethoxybenzothiazole, 1,2,4-triazole, or imidazole, 1/2 part of bis(4 - hydroxy - 5 - t. - butyl - 2 - methylphenyl) sulphide, and 1/2 part of di(octadecyl)-disulphide.

Abstract: 1462227 Radio distance measurement STANDARD TELEPHONES & CABLES Ltd 18 April 1974 16998/74 Heading H4D A distance measuring system includes; in an aircraft, a standard transmitter/receiver assembly 10, the transmission being sinusoidally a.m. modulated (e.g. at 3 kHz) and periodically keyed to give 100 m.sec. bursts; at a ground transponder, a receiver demodulator 20a, a phase locking 3 kHz oscillator 21 producing a C.W. signal, phased with the received modulation and a transmitter 20b replying to the aircraft with a 3 kHz a.m. modulated signal, said signal being received at the aircraft and phase modulated at 13 to give a signal which, after amplitude detection in the receiver 106, is periodically sampled and detected (e.g. every 10 m.sec.) at 14, to give a control signal for a phase shifter 12. This receiver, via ai calibrating phase shifter 17, the 3 kHz modulating signal, to give a phase shifted signal which is further phase reversed every 10 m.sec. in synchronism with the sampling at 14, before being applied as the modulating signal to phase modulator 13. The output of receiver 10b is thus a 3 kHz carrier, phase modulated by a 3 kHz signal, phase reversing every 10 m.sec. If, as desired for the distance between the aircraft and ground, the two 3 kHz signals are in phase quadrature, alternating in their lead/lag relationship, the amplitude of the signal at the output of receiver 10b will remain constant, detector 14 will give zero output and phase shifter 12 will not be adjusted. Otherwise said amplitude will vary with a p.r.p. of 10 m.sec., and phase shifter 12 will be adjusted by the detector's output to produce the phase quadrature relationship. The value of phase shifter 12 is then indicative of the distance. Calibrating phase shifter 17 is used to give a zero distance result when the aircraft is at a nominal zero distance from ground.

Abstract: 1511022 Centrifugal and mixed-flow pumps M STAHLE 24 April 1975 [25 April 1974] 17049/75 Heading F1C A vertical axis centrifugal or mixed-flow pump has means for regulating the delivery comprising a cylindrical tank 3 coaxial with the suction orifice 1a, the tank having an inclined tangential inlet channel 4 for inducing swirl in the tank and an air line 5 in the centre of its base. When the pump operates at maximum water supply, tank 3 is submerged below a feed water level and is filled through its open top, Fig. 1a (not shown). No swirl is therefore induced and the pump works at maximum delivery. Reduction in water supply resulting in the water entering tank 3 exclusively via channel 4, Fig. 2a, gives rise to induced swirl in the rotational direction of rotor 2, thereby forming an air core 6 supplied by line 5. An annular current 7 is thus created producing a reduced delivery.
