Title: Improvements in or relating to devices for determining the radio-activity of solid material dissolved or suspended in a liquid
IPC: G01T7/04
Filed: 1958-11-11
Abstract: 844,733. Measuring radio-activity. PHILIPS ELECTRICAL INDUSTRIES Ltd. Nov. 11, 1958 [Nov. 14, 1957], No. 36222/58. Class 40(3). In a device for measuring the radio-activity of solid material dissolved or suspended in a liquid by evaporating it on a heated layer and detecting the radiation from the residue, the liquid is fed in drops to a heated porous layer which is partly or wholly bounded by a member which limits the area of evaporation. In Fig. 1 the liquid drops on to a tape 1 of inorganic material such as asbestos or filter paper which is heated from below by a device 5. The liquid penetrates the tape and forms a vapour-filled cavity between the tape and heater, spread of this being prevented by a metal ring 8. The latter is heated to a temperature above the boiling point of the liquid by conduction from 5 or by a separate heater. The liquid drops leave residues 6 whose radio-activity is measured by the detector 7. The device 5 can be replaced by a source of radiant heat above or below the tape. If the tape is to be moved continuously the metal ring is replaced by a member which provides a retaining wall only at the sides of the tape.

Abstract: 759,249. Sewing machines. SINGER MANUFACTURING CO. Dec. 24, 1954 [Jan. 15, 1954], No. 37313/54. Class 112. In a four-motion feed mechanism the feed dog is connected to the feed-lift shaft by disengageable means which comprise a first member operated by the feed-lift shaft, a second member connected to the feed dog, a movable device carried by one of said members and movable into engagement with the other member, a spring engaging one end of the movable device, and means for compressing the spring and thereby connecting the movable device with said other member. The feed lift shaft 44 carries a crank arm 68 adapted to be releasably connected to a lever 53 which is journalled on shaft 44 and is coupled to a feed bar carrying the feed dog. When the lever s disconnected from the crank arm, a spring 57 rotates the lever to lower the feed dog into an inoperative position. A rod 201 is screwed at one end into the crank arm and passes through a flared hole 66 in the lever, the other end of the rod having a cylindrical head 205 carrying a radial pin 207 which engages in a spiral cam slot 212 formed in a sleeve 208 mounted on head 205. A sleeve 216 having a domed head 217 is slidably mounted on rod 201 and is interposed between a strong spring 214 and a weak spring 222. Rotation of sleeve 208 in one direction, by means of a handle 209, serves to compress spring 214 and thereby urge head 217 into hole 66 for connecting the lever to the crank arm. Rotation of sleeve 208 in the opposite direction releases spring 214 to allow spring 222 to expel head 217 from hole 66. Specification 721,003 is referred to.

Abstract: 996,449. Moulding electrical components. UNITED AIRCRAFT CORPORATION. Sept. 30, 1963 [Oct. 9, 1962], No. 38371/63. Heading B5A. [Also in Divisions H1 and H2] A method of interconnecting micro-electrical or wafer components or other parts of an electrical assembly comprises linking the parts by elements, encasing the linked parts in a block of insulating material, removing the elements to form tunnels in the block and disposing electrically conductive material in the tunnels. In order to interconnect the components 10, 18, 24, the leads of the components are passed through rods or tubes 30, 32, 34 made, for examples, of polyvinyl alcohol, which is soluble in water, or wax. The assembly is coated with a resin to hold it rigidly during encasement in a block 36 of hydro-carbon resin which is not attacked by solvents of the rods or tubes. The rods are removed from the block by either immersing the block in water if the rods are made of polyvinyl alcohol or heating the block if the rods are made of wax. The tunnels so formed are flushed with a solvent and a conductive material, such as dicumen chromium or nickel carbonyl, is vapour-plated on to the walls of the tunnels by, for example, connecting one end of each of the tunnels to a low-pressure source and vaporizing the conductive material at the other ends of the tunnels, the tunnels afterwards being flushed to remove any residue. Molecular circuits or wafer components may be interconnected in this manner, Figs. 8 and 9 (not shown), and in the former case the circuits are first encapsulated in glass tubes.

Abstract: Articles are made from subdivided horn which has been so dried as to expel the superficial moisture but not so as to remove any water present as part of the horn structure, i.e. natural organic hydration, and then subjected in a closed mould to pressure and subsequently heated under pressure to 130 to 150 DEG  C.  If the horn has been subjected to too great dehydration, it may, prior to drying, be treated with hot water.

Patent GB-1013379-A (GB)
Title: Recovery of acrolein and methacrolein
IPC: C07C47/22
Filed: 1962-10-18
Abstract: Acrolein and methacrolein contained in the gaseous product of the catalytic oxidation of propylene and isobutylene respectively, are recovered by a process which comprises removing the greater part of the water from the product, scrubbing the residue at a temperature below room temperature with an aliphatic ketone containing from 1 to 14 carbon atoms in the molecule, preferably a saturated ketone, and separating the absorbed unsaturated aldehyde from the ketone by flash distillation. The scrubbing is preferably carried out at a temperature for example between 0 DEG  and -50 DEG  C., the flash distillation being preferably carried out in a column at a temperature from 60 DEG  to 125 DEG  C. and the flash distillate is distilled either continuously or batchwise, the scrubbing liquid obtained as a residue in the flash distillation being recycled direct to the scrubbing stage which without purification for drying.  Of the numerous ketones named as methyl amyl ketone, ethyl amyl ketone and diisobutyl ketone are the most preferred. The example describes the oxidation of propylene in the presence of air saturated with water vapour using a catalyst containing molybdenum oxide, bismuth oxide and silica at a reaction temperature of 380 DEG  C., the water from the product being eliminated by passing first through an air condenser and then through a water condenser followed by two refrigerated coolers and finally through a packed scrubbing unit wherein the gas was scrubbed with ethyl amyl ketone at about -25 DEG C., the scrubbing liquid being also pre-cooled to -25 DEG  C.  The ketone loaded with reaction products was continuously withdrawn from the base of the scrubbing unit and fed to a flash column to free the ketone from acrolein. Diisobutyl ketone, methyl amyl ketone and mesityl oxide were also used as scrubbing liquids in the experiments. The ketone freed from reaction products was continuously withdrawn from the base of the flashing column and thereafter recycled to the scrubbing unit without further treatment.  In continuous runs conducted over extended periods of time it was found advisable to add hydroquinone as a stabilizer to the ketone.

Title: Improvements in or relating to the extraction of aluminium
IPC: C22B21/06
Filed: 1960-11-17
Abstract: Aluminium is extracted from aluminium-aluminium carbide mixtures by using a flux containing at least one alkali metal halide and/ or at least one alkaline earth metal halide in a proportion by weight less than that of the mixture to form two phases which are separable. One phase comprises liquid aluminium, the other a slurry of the flux and aluminium carbide which becomes progressively more viscous as the carbide concentration increases until it finally congeals.  The proportion by weight of the flux is preferably equal to that of the carbide in the Al-Al4C3 mixture.  The flux may contain AlCl3 to lower the surface tension thereof and is preferably heated to a temperature of 100  DEG C. or more above its melting point in the pure state, e.g. 850-1000  DEG C. The temperature of the flux may be lowered during the course of the process to get a better separation of the aluminium and a small quantity of an inert substance (Al4C3 or Al2O3) may be added near the end of the process for better separation. Specifications 865,861 and 893,345 are referred to.
