Abstract: 658,940. Electric battery lamps and cigarette igniters. ELBRIC SOC. ANON. Aug. 31, 1949, No. 22649. Convention date, Aug. 31, 1948. [Classes 39(ii) and 75(iii)] A pocket lamp combined with an igniter for cigarettes and cigars comprises a casing 1 for a battery or accumulator 2, and a transversely disposed metal cylinder 10 which is provided with two spaced peripheral cavities 19, 29, containing contact members 20, 25 respectively, adapted to bear against the battery contacts 3, 4 when the cylinder 10 is rotated about its axis, rotation in one direction acting to switch on the lamp 16 and, in the other direction, to complete the circuit through an igniter filament 23. The metal cylinder 10 is retained in position by a semi-cylindrical cover 5 provided with side extensions with lugs to facilitate attachment to the casing by a screw 9 on one side and a stud within an aperture at the other side, longitudinal movement of the cylinder being prevented by end flanges 11, 13 of the same diameter as the cover 5. The flange 13, which is knurled to facilitate rotation of the metal cylinder 10, is attached to the end of the latter by screws, and serves to retain in position a lens 15 at the end of an insulating bush 14 located axially within the cylinder and enclosing a metal bulb socket. An insulated conductor 20 extends through a longitudinal slot in the bush 14 and connects the bulb holder to the battery terminal 3 when the cylinder 10 is rotated in the requisite direction. The circuit is completed from the centre contact of the bulb through a spring 17 and metal cylinder 10 to battery terminal 4. Rotation of the cylinder 10 in the opposite direction brings the battery terminal 4 into contact with the bottom end of an insulated screw 25, the head of which forms one end terminal of the igniter filament 23, the circuit being completed by the other terminal screw 24 which is screwed into the cylinder 10, the latter then being in contact with battery terminal 3. The igniter filament is mounted on a support of poor heat-conductivity, such as mica, provided with a transverse ridge 30, Fig. 3 (not shown), and located within a recess accessible through an opening 26 in the cover 5. The two extreme positions of the cylinder 10 are limited by an arcuate slot 35 therein which receives a screw 36 in the cover, and the intermediate or " off " position is registered when a spring-pressed ball engages an aperture 34 in the cover.

IPC: B64C25/26
Filed: 1939-08-09
Abstract: 544,543. Fastenings. AIR-EQUIPMENT. Aug. 9, 1939, Nos. 22947 and 22948. Convention dates, Aug. 12, 1938, and July 26, 1939. [Class 44] [Also in Group XXXIII] Relates to means for locking retractable devices for aircraft, such as wheels, skids, floats, and cupolas in operative and inoperative positions, and is described with reference to undercarriage mechanism of the kind having resilient legs 3 and a pair of folding struts comprising members 8, 9 adapted to be rotated one on the other by an electric motor arranged in a casing 6 at the pivotal connection of the members as described in Specification 495,759, [Group XXXIII]. According to the invention, the structure is rendered rigid, or triangulated, in the operative position shown in Fig. 1 by a pair of bars 22 pivoted to the legs 3 and joined at their other ends to an engaging head 23 adapted to be locked automatically by a pair of hooks 31, Fig. 3, when the strut 8, 9 is straightened into its operative position. The bars 22 are held in position for locking by an adjustable spring- controlled strut 25. The hooks 31 are pivoted in a casing 33 resiliently secured to the member 9 and are engaged by spring-pressed devices 35 tending to hold them in the open or closed positions. The hooks are held in the closed position shown by a roller 36 on a spring- actuated'arm 37, in which position, a rod 48 is moved to close a contact to operate an indicator on the pilot's dashboard. When the undercarriage is being retracted, a cam withdraws the roller 36 and allows the engaging head 23 to be withdrawn against the action of the spring- pressed devices 35, which then maintain the hooks in the open position. In a modification, the roller 36 for locking the hooks is operated by an electromagnetic switch device which acts in conjunction with a switch operated by the rod 48 and a press-button switch operated by the pilot for controlling the operation of the electric motor for folding and unfolding the members 8, 9 one on the other. The device for locking the undercarriage in the inoperative position comprises an engaging head 22b, Fig. 10, on the strut member 9, adapted to engage a pair of spring-controlled pivoted hooks 31b.

Patent GB-383327-A (GB)
Title: A hard metal and method of producing the same
IPC: C22C1/05
Filed: 1931-08-18
Abstract: A hard alloy consists of 50 per cent or more by weight of titanium carbide and an auxiliary metal, for example iron, cobalt, nickel or their alloys or alloys of cobalt, chromium, and tungsten with or without carbon.  The titanium carbide may be supplemented by about 10-20 per cent of other carbides such as tungsten, molybdenum or tantalum carbides.  The pulverized carbide is mixed with the powdered auxiliary metal, pressed to form the final body and then heated to a high temperature preferably in hydrogen, or an inert atmosphere or in vacuo.  The bodies may also be heated first to a moderate temperature to render them easily workable and then finished by heating to the high consolidation temperature. Chemical compounds of the auxiliary metals, for example, oxides or oxalates may be pulverized or brought into solution, then mixed with the titanium carbide and heated in a reducing atmosphere to obtain a finer distribution of the auxiliary metal in the carbide, the mixture being then consolidated at the higher temperature. In another method the bodies are pressed out from the titanium carbide with or without a small addition of the auxiliary metal and sintered at a high temperature.  The porous sintered body is brought into contact with the auxiliary metal and heated so that the molten metal is absorbed by the sintered body. Reference has been directed by the Comptroller to Specification 361,363.

Title: Extraction of polypeptide-containing anorexigenic substance and polypeptide-containing fat-mobilizing substance from animal urine
IPC: A61K35/22
Filed: 1965-06-01
Abstract: A polypeptide-containing fat-mobilising substance, FMS-1A, and a polypeptide-containing anorexigenic substance, FMS-1B, are prepared from the urine of fasting or cold-acclimatised animals by addition, at an acidic pH, of an alkanol to give a precipitate, FMS-1, comprising the mixed crude substances, and extracting the precipitate firstly with water to give a solution of FMS-1A and then with dilute aqueous alkali to give a solution of FMS-1B.  The word "anorexigenic" is said to mean capable of causing loss of appetite.  The animals, preferably rats, or horses, goats, sheep, dogs, cows, or rabbits, may be fasted by first feeding on a high fat diet for several days, followed by removal of all food, with urine collection over the next 24 hours; the cold acclimatisation is effected by transfer of the animal kept at room temperature, to an environment at 5 DEG C. for 24 hours to 3 days, with concomitant urine collection.  FMS-1 is precipitated with, e.g. methanol, ethanol or propanol, from the urine acidified to pH 5.3 with benzoic, acetic, hydrochloric or sulphuric acid.  The alkali may be aqueous alkali-metal or alkaline earth metal hydroxide or carbonate.  The two substances FMS-1A and 1B may be purified and obtained in solid form by re-precipitation from the solutions with acidified alcohol, with subsequent dissolution of the precipitate in water or dilute alkali (whichever is appropriate), and lyophilisation.  Also described is the preparation of a similar polypeptide, "Hypox FMS", by the same process but from urine from fasted hypophysectomised rats.  This substance has anorexigenic activity, but no effect upon fat metabolism.  FMS-1A and 1B are also said to cause hypoglycemia.  The invention includes injectable compositions of FMS-1A and 1B with an inert carrier.

Title: Improvements relating to thoria sols
Inventor: BARRETT WAYNE THOMAS
IPC: G21C3/48
Filed: 1960-07-05
Abstract: A hydrothermally stable sol comprises an aqueous dispersion of spheroidal theria particles of colloidal size having surface layers of silica in amount at least sufficient to impart to them a negative charge as measured electrophoretically, the sol containing sufficient base (e.g. sodium hydroxide) to give a solution pH of 7,0 to 11,0, the dispersion otherwise being electrolyte-free.  The particles have a weight median diameter of 30 to 200 mmu.  The sol is prepared by rapidly mixing a thoria sol containing 5 to 10% by weight thoria, with a freshly prepared silica sol containing 1 to 2% by weight silica.  The weight ratio of thoria to silica is from 1 : 1 to 10 : 1.  The initial thoria sol is prepared by removing anions from a solution of a thorium salt of a strong monobasic acid (e.g. thorium nitrate, thorium chloride or thorium perchlorate) by dialysis or electrodialysis using an anion-permeable membrane, by ion exchange using a resin in hydroxide form, by decomposition of the salt of a volatile acid, or by electrolysis of a thorium salt the anion of which is oxidized to a volatile compound.  The silica sol has a micelle size of less than 5 mm , and is prepared by passing a solution of sodium silicate through a cation exchange resin.  After mixing the two sols the sol of silicaclad thoria is stabilized by adding the base to bring the pH to between 7 and 11.  It may be purified by heating under non-evaporative conditions, cooling and contacting with a deionizer, followed by the addition of more base to restore the pH between 7 and 11.  The sol may be concentrated by evaporation to a solids content of up to 60% by weight.  The sol may be used in a nuclear power reactor of the breeder type to surround a source of neutrons, e.g. a uranyl sulphate solution. Examples are given.  Specification 905,919 is referred to.
