Patent GB-303372-A (GB)
Title: An automatic control device, particularly for preventing liquids from boiling over
IPC: A47J27/62
Filed: 1928-12-31
Abstract: 303,372. Rusche, T. W. A. Dec. 31, 1928. [A Specification was laid open to inspection under Sect. 91 of the Acts, Jan. 1, 1929]. Signals.-A device for initiating an operation comprises a small float which is raised to actuate a balanced train of levers by means of a pawl adapted to engage the longer arm of a check lever having arms of unequal length, the movement of the shorter arm thereof releasing a spring- controlled member to bring about the desired movement. As applied to prevent a liquid such as milk from boiling over, the raising of a float 2 secured to a rod 1 displaces a balanced arm 3 to the spindle of which a flat lever 5 is rigidly secured. A pawl 7 at the end of the lever 5 is thereby disengaged from the longer arm of a lever 6 pivoted at 34 and itself supporting by its shorter arm the longer arm of a second lever 9, pivoted at 36, which is thus freed. The lever 9 which normally supports a lever 10 pivoted at 37, releases that lever and a stop face 13 thereon ceases to arrest a pawl 39 connected to a drawbar 16 adapted to be actuated by a spring 12 held under compression when the face 13 engages the pawl 39. The draw-bar 16 actuates a gas tap or electric switch through a Bowden wire 17. To re-set the device, a slotted bar 25 is pulled to engage first a lever 31 which engages an arm 30 fixed to the spindle of the lever 10 to re-set that lever and then arms 29, 28 secured to the spindles of the levers 9, 6, the balance lever 3 is set by a lever 24 and finally the draw-bar 16 is pulled to its tensioned position by a hook 26. The device may be positioned above a milk vessel on a bracket 27. The Specification as open to inspection under Sect. 91 (3) (a) comprises a tension spring 12 restrained by engagement of the pawl 39 with the opposite side of the member presenting the face 13. This subject-matter does not appear in the Specification as accepted.

Abstract: 839,081. Coating by vapour deposition. ' WESTINGHOUSE ELECTRIC CORPORATION. Dec. 13, 1957, No. 38775/57. Class 82(2) [Also in Group XXXVI] In a process of evaporating the metal of a metal body to deposit a coating thereof on a member disposed below the metal body, the temperature of the body is raised to the evaporation point so as to effect the evaporation of volatile impurities and metal, the impurities and metal flowing toward the member are collected for an initial time period to prevent them reaching the member, and pure metal is allowed to deposit on the member only after the impurities volatilizable at the evaporation temperature have been driven off. The process is applicable to the deposition of doping material upon a semiconductor such as Ge or Si to provide a P-N junction therein. As shown, Ge wafers 14 are heated by graphite heater 15 and coated with Al by evaporation from body 28, impurities from said body being intercepted during the initial stage of the evaporation by shield 30 which is swung aside when all the impurities have been dissipated. Other metals which may be evaporated are In, As, Sb, Ga and Ag. Pure Al for making a transistor junction may be produced by evaporating Al on to a glass plate and then stripping off the resulting film.

Title: Improvements in and relating to the production of ethers
Inventor: CLARK Duncan
IPC: C07C43/16
Filed: 1963-10-14
Abstract: Alkyl alkenyl ethers are prepared by contacting a terminal olefine with a substantially anhydrous solution of a salt or co-ordination compound of palladium, said solution containing an alcohol, and removing the alkyl alkenyl ether from the reaction zone immediately upon formation.  Up to 10% by weight of water may be tolerated in the reaction mixture.  Specified olefines are ethylene, propylene and butene-1; specified alcohols are methanol, ethanol, isopropanol and t-butanol.  The palladium compound may be palladous chloride or acetate, lithium or sodium chloropalladite, dichloro bis-(benzonitrile) palladium (II) or allyl palladous chloride.  The co-ordination compounds of palladium may be formed in situ.  The palladium compound may be dissolved in an excess of olefine, if this is liquid, or in a polar or nonpolar solvent, e.g. benzene, acetic acid, dimethylacetamide, benzonitrile and acetonitrile. It is preferred to maintain the concentration of the alcohol in the reaction solution at a low level, e.g. less than 2 mols./litre reaction solution. The reaction may be effected at temperatures and pressures up to 300 DEG  C. and 100 atmospheres.  The ether may be removed from the reaction zone by distillation, optionally with the aid of entrainment in a stream of the olefin, if this is gaseous. Examples relate to the preparation of methyl vinyl ether; some acetal is obtained as a by-product.
