Patent GB-794416-A (GB)
Abstract: 794,416. γ-Dihydroionone. FIRMENICH, A., FIRMENICH, R., FIRMENICH, G., and FIRMENICH, R., [trading as FIRMENICH & CO., SUCCESSEURS DE LA SOC. ANON. M. NAEF & CIE]. April 4, 1955 [April 12, 1954], No. 9722/55. Class 2 (3). γ-Dihydroionone is prepared by a process which comprises heating the hydrochloride of α-dihydroionol acetate with an alkali metal salt of one or more organic carboxylic acids containing 1 to 20 per cent by weight of the carboxylic acids in the free state or with an alkali metal alcoholate in an inert solvent, hydrolysing the thus obtained acetates of the isomeric dihydroionols at ordinary temperature and then oxidizing the thus formed mixture of isomeric dihydroionols at a temperature below +7‹ C. with a cooled solution of chromic acid in a mixture of acetic acid, water and benzene so as to obtain a mixture of γ- and α- and perhaps also #-dihydroionones from which the γ-isomer may be obtained. In a modification of the process the removal of hydrogen chloride may be effected by means of a dry alkalimetal salt of an organic carboxylic acid with more than 2 carbon atoms in an inert solvent. In the example, α-dihydroionol is heated with acetic anhydride and potassium acetate, the α-dihydroionol acetate obtained is dissolved in acetic acid and converted with gaseous hydrogen chloride to 3-chloro-tetrahydroionol acetate which is heated with potassium laurate and dry xylene to obtain a mixture containing α- and γ-ionols, the latter is dissolved in acetic acid, benzene, water and potassium bisulphate and treated with an aqueous acetic acid solution of chromic acid. Alternative reagents for the removal of the hydrogen chloride specified include alkali metal salts of undecylenic, abietic, stearic, benzoic and phthalic acids, sodium or potassium alcoholates with less than six carbon atoms, dry sodium or potassium methylate or tertiary butylate mixed with an aliphatic carboxylic having more than two carbon atoms. The crude mixture of dihydroionones obtained by the chromic acid oxidation is treated with semicarbazide acetate and the γ-isomer is separated by fractional crystallization the semicarbazone is hydrolysed by steam distillation in the presence of tartaric acid or by boiling with chloroform and aqueous phthalic anhydride and the product is treated with Girard's reagent T or P or Viscontini's N,N- dimethyl - glycine - hydrazide hydrochloride to obtain pure γ-dihydroionone. Non-oxidized ionols may also be separated from the γ- ketone by heating with a boric ester and distilling off the ketonic fraction. Specification 794,417 is referred to.

Title: Water purification by ion exchange
IPC: B01J47/04
Filed: 1980-11-05
Abstract: A condensate polishing or other water purification process for purifying low solids content water is conducted by passing the water downflow through cation and anion exchange resins in one or more primary beds 4, 5 and finally through a final bed 6 of cation exchange resin and the cation exchange resin of the final bed is regenerated as part of a combined bed 12 containing cation exchange resin from the primary bed(s), and after regeneration the cation exchange resin from the least contaminated part 12a of the combined bed only is used as the resin in the final bed 6.

Title: Electronic wrist watch and process for casing such watch
IPC: G04C3/00
Filed: 1980-06-19
Abstract: PCT No. PCT/CH80/00072 Sec. 371 Date Mar. 16, 1981 Sec. 102(e) Date Mar. 3, 1981 PCT Filed Jun. 19, 1980 PCT Pub. No. WO81/00311 PCT Pub. Date Feb. 5, 1981.At the time of the casing of a watch in the back of which a diaphragm (19) is placed, an insulating and inert transparent liquid is caused to penetrate into the interior of the case by placing the whole in an enclosure under negative pressure. The air is exhausted, and the liquid in question comes to occupy the space included between the module (1) and the walls of the case. A small quantity of air contained under the diaphragm (19) expands under the effect of the negative pressure and causes this diaphragm to swell, which gives a compensating volume allowing thereafter the thermal expansion of the liquid within the case and without subjecting the walls of the latter to stresses.

Title: Flame-failure devices for gas- burning appliances
IPC: F23N5/06
Filed: 1981-04-29
Abstract: A flame-failure device for a gas- burning appliance includes a hollow, sealed body containing water or other aqueous liquid, the body consisting of a capillary tube (31), a phial (32) at one end of the tube (31) and an expansion unit (26) at the other end thereof. In use the phial is heated by a pilot flame. When the liquid in the body boils, the unit (26) expands and an abutment (27) on it engages a plate (22) at one end of a rod (21). The resulting movement of the rod opens a gas valve (15, 16, 17) in the supply line to a main burner. A heavy compression spring (23) acts on the plate (22) to resist expansion of the unit (26). Only when the temperature in the phial exceeds about 200 DEG C does the liquid boil sufficiently to open the gas valve. If the pilot flame fails, the phial cools and the expansion unit contracts thus allowing the gas valve to close. <IMAGE>

Filed: 1980-10-28
Abstract: A connector assembly, for use in connecting a wiper arm and a wiper blade for pivotal movement of the blade in relation to the arm about a common axis which in use is substantially perpendicular to the surface to be wiped, comprises two basic parts, namely a first part (11) for attachment to the wiper arm and a second part (12) for attachment directly or indirectly to the wiper blade, the parts being pivotally connected together for relative angular movement about the common axis (13). The assembly includes a discrete element (33) arranged for rotation about the common axis in relation to one of the parts (11) and there are two first abutment faces (31, 32) on that part (11), and two second abutment faces (36, 37) on the discrete element (33), the second faces (36, 37) being arranged to co-operate with the respective first aces (31, 32) to limit the range of relative angular movement of the two parts (11, 12) about the common axis (13). A coil spring (38) acts between the two parts (11, 12), and a tail (40) of the spring (38) couples the element (33) to the other part (12).
Patent GB-2084283-A (GB)
Title: Welding to structural members
IPC: E04G1/12
Filed: 1981-08-20
Abstract: The heat of welding substantially impairs the strength of aluminum structural members. This problem is overcome by welding to one or more sacrificial flanges 22, 24 integrally formed with such a member. With the welding restricted to the flange(s) the weakening effect of the welding operation is thereby isolated from the load-bearing portion of the structural member. Load-bearing shoring frames made from aluminum tubing are used to illustrate this invention. The frame legs are each preferably extruded with a pair of spaced parallel sacrificial flanges. The horizontal bracing extending between the legs are welded to the respective pairs of sacrificial flanges on each respective leg. The welding is sufficiently distant from the load-bearing portion of the leg so that the heat of welding dissipates sufficiently before the leg proper is affected thereby. <IMAGE>

Title: Method of producing an alloy or a mixture of elements in the surface of a substrate
Inventor: SORENSEN GUNNAR
IPC: H05K3/18
Filed: 1982-03-15
Abstract: The effect of energetic ions on films of a chemical metal component on the surface of a substrate can change physical and chemical properties of said surface. By choosing the energy of the ions in relation to the thickness of the film, reactive mixing processes will occur at room temperature, when some of the ions penetrate the film and into the substrate. When the method is applied to a porous surface, metal may be embedded in the pores. The method can be performed in a selective way and applied on metal compounds, when the metal can act as a catalyst in electroless metal deposition, the method can be used to produce printer circuitry by a completely additive process within micro-electronics.
