Title: Improvements in or relating to electrical control for friction wheel screw-presses
IPC: B30B1/18
Filed: 1936-07-08
Abstract: 462,800. Machinery guards. REISSMANN AKT.-GES., MASCHINENFABRIK UND EISENGIESSEREI, A. July 8, 1936, Nos. 18943 and 18944. Convention dates, July 9, 1935 and June 15, 1936. [Class 80 (iv)] Relates to friction-wheel screw-presses for moulding ceramics and of the kind in which the movement of the screw spindle 1 is controlled electrically, and comprises means whereby the control switches are moved positively into correct position on the starting of the machine, and means for preventing the starting of the machine should the mould-charging hopper lie in the path of the die carried by the screw. The fly-wheel 2 on the screw 1 is driven by friction discs 3, 4 on a shaft movable by a lever 13 under the influence of a spring 30 and a solenoid 14. A disc 5 on the screw engages a slotted head 6 of a rod 8 carrying a contact piece 11 adapted to bridge pairs of contacts a ... d according to the position of the screw. A knob 38, Fig. 3, on a spring-controlled rod 39 for starting the machine is carried by the charging-hopper and is only in position to operate the starting switch E when the hopper is removed from beneath the screw. If the contacts a are bridged, and the switch E is closed, a switch A is operated to energize the solenoid 14 whereby the screw 1 descends while a core of the switch A operates a lever 49 to render a main pressure switch B inoperative. When the contacts b are bridged, the solenoid is de-energized and the screw descends under its momentum to apply the preliminary pressure to the mould. No action takes place when the contacts c are bridged, but when the contacts d are closed, a reverser switch D is operated so that, when the screw 1 rises and the contacts c are again closed, the solenoid is again operated and causes the screw to descend with strong pressure on the mould. On reaching the lowest position, the contacts d are again bridged, the reverser switch is again operated to de-energize the solenoid, and the screw rises under the influence of the friction wheel 3 that is pressed by the action of the spring 30 into contact with the fly-wheel 2.

Abstract: 975,033. Aircraft instruments. ELLIOTT BROS. (LONDON) Ltd. Aug. 15, 1963 [May 17, 1962], No. 19121/62. Heading B7W. [Also in Division G1] A system for indicating the performance of an aircraft engine in which data relating to different variables has to be analysed, comprises a computer 1, 2, 3 whose output signal represents the sum of any departures of the variables from respective predetermined reference values and an indicating- instrument 6 responsive to this signal to indicate whether the sum exceeds a predetermined safe value. The computer comprises a section 1 which receives signals representing each variable and reduces them to a common denominator, e.g. electric current to feed a comparison section 2, also fed from a flight plan unit 4 with signals representing the required performance of the engine, after which any error signals are added in section 3 irrespective of sign. A lamp corresponding to each variable will flash if its error signal is excessive and if a corresponding switch 7 is pressed, the instrument 6 will be fed from that source alone and its translucent dial will be illuminated over the appropriate tolerance band for that signal. The flight plan may be pre-recorded on punched or magnetic tape. Servo-mechanism controlled by the computer may be brought in to correct any excessive error and may shut off the engine if the error is excessive. To monitor the performance of several engines the computer may be switched electronically from one engine to another and should one engine show too great an error signal, the computer may be held on that engine, while a stand by computer takes over for the remaining engines.

Title: Process for separating azeotropic mixtures of esters of aliphatic carboxylic acids and alcohols
IPC: C07C29/86
Filed: 1964-05-08
Abstract: An ester of an aliphatic, saturated or unsaturated, carboxylic acid and a lower aliphatic alcohol, which forms an azeotrope with the corresponding free alcohol, is separated from admixture with the free alcohol by distilling the mixture in the presence of a halogen derivative of a hydrocarbon, which forms an azeotrope with the alcohol boiling at least 5 DEG  C., but no more than 40 DEG  C., below the boiling-point of the ester/alcohol azeotrope, and passing the vapours through a fractionating column whereby a mixture of the alcohol and the halohydrocarbon distils over from the top of the column.  Water is added to the distillate; and the halohydrocarbon, which separates out, is returned to the distillation zone.  The process may be carried out during an alcoholysis reaction.  In an example, butyl acrylate is produced by boiling methyl acrylate with butanol in the presence of trans-1,2-dichloroethylene.  The reaction mixture also contains p-toluenesulphonic acid and phenothiazine. Another example relates to the preparation of 2-ethylhexyl acrylate by reacting methyl acrylate with 2-ethylhexanol.  A further example relates to the hydrolysis of methyl acetate by means of water in the presence of a cation exchange resin; and the separation of methanol from non-hydrolysed ester using dichloromethane as auxiliary.ALSO:An ester of an aliphatic, saturated or unsaturated carboxylic acid and a lower aliphatic alcohol, which forms an azeotrope with the corresponding free alcohol, is separated from admixture with the free alcohol by distilling the mixture in the presence of a halogen derivative of a hydrocarbon, which forms an axeotrope with the alcohol boiling at least 5 DEG C., but no more than 40 DEG C., below the boiling-point of the ester-alcohol azeotrope, and passing the vapours through a fractionating column whereby a mixture of the alcohol and the halohydrocarbon distils over from the top of the column.  Water is added to the distillate, and the halohydrocarbon, which separates out, is returned to the distillation zone.  In an example methanol is separated from methyl propionate using 2-bromopropane as auxiliary liquid. Trichlorotrifluoroethane may also be used as auxiliary liquid. For the separation of ethanol from ethyl acetate, either trichloroethane or trans-1-bromo-2-chlorethylene may be used as auxiliary liquid.  The process may be carried out during an alcoholysis or a hydrolysis reaction (see Division C2).

Title: Process for forming suspension emulsion interpolymers
IPC: C08F265/04
Filed: 1975-05-08
Abstract: 1460139 Acrylic elastomers STAUFFER CHEMICAL CO 8 May 1975 [1 July 1974] 19394/75 Heading C3P A method of making acrylic elastomer containing interpolymer particles by the emulsion polymerization of a monomer charge containing at least one monomer capable of forming a cross-linked acrylic rubber having a glass transition temperature of less than 25 C. and a monomer having at least two ethylenically unsaturated bonds as a cross-linking agent to form an aqueous emulsion which contains cross-linked acrylic elastomer particles and by thereafter suspension polymerizing a monomer charge comprising vinyl chloride in the presence of the acrylic elastomer particles is characterized in that a sulphonated salt of an ethoxylated alkyl phenol is used as the emulsifier in the emulsion polymerization step. Numerous examples of the monomer that form acrylic elastomers, and of optimal monomers which together with the vinyl chloride are thereafter polymerized in the presence of the acrylic elastomer are specified. The preferred crosslinking agent is butylene glycol diacrylate. A coagulant may be added to the suspension batch either prior to, during, or after the suspension polymerization is run in order to facilitate complete precipitation of the elastomer latex particles. Suitable coagulants are calcium chloride, ferric chloride, barium chloride, magnesium chloride, aluminium chloride, aluminium chloride hexahydrate, aluminium sulphate, calcium sulphate and polyvinylpyridinium butyl chloride. Suspending agents such as methyl cellulose, hydroxyethyl cellulose, hydroxypropyl cellulose, carboxymethyl cellulose, talc, clay, polyvinyl alcohol and gelatin are present in the aqueous emulsion of the rubber polymer particles. Polymerization may then be initiated by reacting the vinyl chloride in the presence of the acrylic elastomer particles at 45-75 C. for 2-12 hours. Preferred products contain 30-55% by weight of the cross-linked acrylic elastomer emulsion polymer and 45-70% by weight of the vinyl chloride suspension polymer surrounding and/or homogeneously dispersed throughout the mass of the said elastomer emulsion polymer. In the specific Example (1) a blend of n-butyl acrylate, 2-ethylhexyl acrylate and butylene glycol diacrylate is emulsion polymerized in the presence of the sodium salt of an alkyl aryl polyether sulphonate emulsifier to form an aqueous emulsion containing cross-linked acrylic elastomer particles to which is added vinyl chloride and calcium chloride, as coagulant. The comparative example uses the same monomers and conditions except that sodium lauryl sulphate is used in the emulsion polymerization step. Reference has been directed by the Comptroller to Specification 1,362,277.
