Abstract: 534,633. Aliphatic acids and ketones. KODAK, Ltd. Sept. 7, 1939, No. 25335. Convention date, Sept. 7, 1938. Drawings to Specification. [Class 2 (iii)] Primary aliphatic alcohols including glycols, glycerol, and other polyhydric alcohols, are oxidized to acids by introducing the alcohol and an oxidizing gas such as air , or oxygen or ozone continuously into a solution of a metal salt catalyst in an aliphatic acid, and the acid produced is removed continuously. The invention also includes the similar treatment of aliphatic secondary alcohols with the production of ketones. Preferably an aliphatic aldehyde is introduced together with the alcohol to maintain the activity of the catalyst. The catalyst may be a salt of a metal having an atomic number 25-29 or a metal of the 8th group of the Periodic system such as one or more acetates of cobalt, nickel and copper. Preferably the metal has a valency higher than its lowest valency. In examples (1) a column is charged with a solution of cobalt acetate in glacial acetic acid and air and acetaldehyde are admitted until the colour becomes green ; ethyl alcohol, acetaldehyde and air are then supplied, acetic acid being distilled off through a reflux condenser ; (3) acetaldehyde and butyl alcohol are treated, yielding butyric acid and small quantities of butyl acetate and butyl butyrate ; (5) with an increased quantity of alcohol over the quantity used in the preceding examples from. one-fourth to one-half of the product is ester; (6) an ester which may have been produced by the process, is dehydrogenated to yield aldehyde and acid, or a part of the alcohol feed may be dehydrogenated to aldehyde, the aldehyde being supplied to the process ; (7) the ester produced is returned to the oxidation column to diminish the further production of ester, a result which can also be effected by admitting water.

Abstract: 278,355. Corson, M. G. Oct. 4, 1926, [Convention date]. Annealing, tempering, and otherwise modifying physical characters of metals.-In a process for heat-treating copper base alloys containing 3.7 to 6.7 per cent of silicon, the alloy is heated to a temperature of 500‹-800‹ C. to form a solid solution of copper and silicon which will be supersaturated at room temperature and then quenched to preserve such condition of solid solution. The alloy may be hot worked at 500‹ C. after the heat treatment and quenched from a temperature above 500‹ C. In an example, an alloy containing approximately 6.5 per cent of silicon is heated to a temperature of 720‹-820‹ C. worked at a temperature above 720‹ C. and quenched from a temperature of 750‹-800‹ C. The alloy may be cold worked after this treatment and the working may alternate with further annealing at 750‹-800‹ C. followed by quenching. The alloys may contain small amounts of other metals such as tin (up to 2 per cent), zinc (up to 5 per cent), or aluminium (up to 3 per cent).

Filed: 1974-06-07
Abstract: 1429450 Can treating apparatus STOLLE CORP 7 June 1974 [13 July 1973] 25384/74 Heading B8T Apparatus for treating cans prior to filling comprises means for transporting the cans with their open ends facing downward, through a series of treatment zones where they are sprayed with fluid from nozzles. Semi-cylindrical support members 2 on which the cans 1 are carried are secured to an endless line 8, the line being driven over pulleys (not shown) thereby moving the cans through the treatment zones. The cans, which are held loosely by the support members 2, are prevented from falling out by point contact members 14a, 14b. Fluid is sprayed on to the cans from a series of nozzles 6, 6a, 6b, the force exerted by the fluid ejected from the lower nozzle 6a being sufficient to lift each can from its support member until its base abuts a rail 7; this coupled with the transiational motion of the support members causes each can to rotate about its axis thereby exposing the whole of its inner and outer surfaces to the fluid jets. The treatment zones are enclosed in a series of tubes which are connected together to produce a form resembling a helix, Fig. 3 (not shown), different convolutions of the helix being devoted to different stages of the can treatment. The cans may initially be sprayed with a washing medium, then rinsed, after which they may be sprayed with a treatment fluid such as a protective coating and finally dried or cured in a stream of hot air.

Abstract: 1,046,827. Route setting systems. INTERNATIONAL STANDARD ELECTRIC CORPORATION. June 18, 1965 [June 24, 1964], No. 25866/65. Heading B7H. In a route-setting system, in which relay sets for the control of track apparatus, e.g. the points of a crossover are connected in a circuit simulating the track network, each relay set includes route search relays for connecting the relay circuit links in accordance with the required route and route-setting and locking relays connected to the links of the required route for setting and locking the associated track apparatus. The relay set for a crossover includes routesearch relays USF1 and USF2, UST1 and UST2, one in each link simulating an approach track to the crossover and contacts of these relays ensure the transmission of the route search signal to adjacent relay sets in dependance on the required route. The search signal is applied via contacts of locking relays WL, when the points of the crossover are unlocked for both through and crossover lines or via contacts of the setting relays WP when the points are locked for the through lines, when the points are set to normal, or locked for the crossover line, when the points are set to reverse. The setting and locking circuit, Fig. 3 (not shown), includes an auxiliary relay, which if the crossover points are not set to the correct position for a required route, is energized to prevent operation of the locking relays until the points are correctly set. Operation of the relay also applies operating voltage to the setting circuit via an arrangement which reduces the load on the power supply by ensuring that the setting circuit of each relay set is energized in turn.

Abstract: 1,168,477. Channel-shaped laminate. HAY'S INTERNATIONAL SERVICES Ltd. 12 Sept., 1967 [14 June, 1966], No. 26421/66. Heading B5N. A method of forming channel-shaped laminated structures consisting of a layer of wood sandwiched between metal sheets comprises the steps of laying up the sheets of metal with the layer of wood between them, and with an adhesive of the kind which is cured by heat and pressure between the surfaces which are to be secured together, bending the assembly to channel shape so that the internal angle of the bends is somewhat less than the desired final bend angles, and moulding the assembly under heat and pressure between male and female mould members to cure the adhesive. The male mould member 17 has bottom 19 and side surfaces 18 and the female member is split longitudinally and capable of being subjected to pressure in three directions to urge it against the surfaces 18, 19 of the male mould member. The moulding operation comprises inserting the bent assembly between the mould members, bringing the mould members together in the direction of the depth of the channel, separating the mould members by a small distance by relative movement in the opposite direction, applying pressure to the parts 20, 21 of the female mould member to urge them towards each other so as to grip the side walls of the assembly between the male and female members, again bringing the mould members together in the direction of the depth of the channel whilst maintaining said pressure, maintaining pressure on the female mould member to press the assembly against both the bottom and side surfaces of the male mould member, applying heat to cure the adhesive, and opening the mould. As described the wood layer is formed by cutting a block consisting of a plurality of strips of balsa wood across the grain of each strip to form a sheet and sanding the cut surfaces. The metal layers are of degreased aluminium or aluminium alloy, and the adhesive is polyvinyl acetal/phenolic resin adhesive which is applied as a preformed film or of which the phenolic component is applied as a liquid to the two surfaces to be joined and the vinyl component applied as a powder to one of the coated surfaces. The assembled layers are initially bent, whilst supported on a table, by a pair of rollers each movable in an arcuate path. During the moulding step the pressure may be released briefly whilst heating to allow the escape of vapours. The moulded structure may be cooled whilst under pressure. The finished structures may be used as container halves, in which case the outer metal sheet at one longitudinal edge of the channel extends beyond the edges of the other layers.
