Title: Improvements in or relating to selectors comprising wipers adapted to be moved to fixed contacts in a contact position of the selector
IPC: H01H67/06
Filed: 1955-11-03
Abstract: 776,731. Electric selectors. PHILIPS ELECTRIC INDUSTRIES, Ltd. Nov. 3,1955 [Nov. 6, 1954], No. 31477/55. Class 40 (4). A wiper carriage of a selector carries a movable wiper urged towards fixed contacts by a spring and engaging the contacts only when the carriage is stationary, means being provided to lock the wiper when it is disengaged from the contacts and the carriage being provided with an inertia member biased by a spring and capable of being displaced by its inertia against the spring to unlock the wiper when the carriage is stopped. The embodiments show arcuate banks of contacts with wipers rotatable about a shaft, and in Fig. 1 a locking arrangement is shown with two masses 24 and 29 such that when the carriage is halted the mass 29, pivoted at 30, deflects a spring-loaded latch arm 36 which is pivoted at 35. The latch releases an arm on the wiper 26 which pivots about 23 and is moved by a spring 28 to engage a fixed contact. When the carriage starts in the direction of arrow P both masses move about their pivots between stops 21, 22 and 31, 32, to automatically re-engage the latch. Figs. 2 and 3 show a selector in which a contact bank comprises a pile of semi-circular ethoxylin resin moulds in which contact wires or plates are embedded; the moulds being secured together by hardened ethoxylin resin. Moulds 50 support semicircular metal plates 51 and adjacent moulds 52 support inwardly projecting flattened contacts 53. Radially symmetrical pairs of wipers 65, 66, supported between insulating cylinders 64 on a shaft 61, establish a direct connection between each plate 51 and an associated contact 53. Moulds 54 and 56, respectively, support a continuous semi-circular wire 55 and separate contacts 57 with rounded heads. Movable wipers 73 and 74 with shovel-headed ends make a direct connection between each continuous wire contact 55 and an associated contact 57 when the carriage supporting the wipers on spindles 69 is brought to rest. The spindles 69, carry a wiper mounting block 72, Fig. 2, and extend between a plate 68 and a stop-wheel 62 on the carriage. The bottom mould 58 carries an inwardly projecting toothed semi-circle, the teeth of which are engaged by an arm 76 mounted on the bottom of the wiper mounting- block 71. A spring 80 secured to the arm 76 biases the wipers 73, 74 towards the contacts, but, as shown, in Fig. 2, a bifurcated end 78, 79 of arm 76 engages a mass 81 which is pivoted about a spindle 70 and held against arm 76 by a spring 82. When the carriage is halted from rotation in the direction of arrow R, the mass 81 is thrown round to release arm 76 and engage the wipers. On release, arm 76 engages between two teeth of semi-circle 59 and when the carriage starts up the arm is thrown out from between the teeth to effect disengagement of the wipers and latching of the arm with the mass 81.
Patent GB-740868-A (GB)
Title: Improvements in or relating to the separation of niobium and tantalum
IPC: C01G33/00
Filed: 1953-11-13
Abstract: Niobium and tantalum are separated at least partially by reducing a mixture of the pentoxides to a stage in which a niobium-enriched tetroxide phase is present, dissolving said phase in hot sulphuric or phosphoric acid, to the former of which selenium oxychloride may, if desired be added, and separating the dissolved tetroxide phase.  In the example, a mixture of oxides is reduced with hydrogen containing water vapour at a partial pressure of 0.04 mm. and the product treated with 80 per cent by weight sulphuric acid at 200 DEG C.  The mixture is filtered and acids of niobium and tantalum are precipitated, e.g. with ammonia. When using hydrogen, a low water content favours a pentoxide phase poor in niobium and a tetroxide phase rich in tantalum and a high water content favours the reverse. Carbon monoxide, if desired in admixture with carbon dioxide may alternatively be used as reducing agent.  More intense reduction leads to a pentoxide phase poor in niobium and less intense reduction to a phase poor in tantalum.

Title: Improvements in or relating to bleaching of cellulose fibres
IPC: D06L4/70
Filed: 1945-11-30
Abstract: Cellulose fibres are bleached by treating the fibres with active chlorine in aqueous solution followed by optional rising and centrifuging, and then subjecting them to the action of a calcium and magnesium sequestering agent, whereupon the fibres are again treated with chlorine, e.g. in a bath containing less active chlorine than the first.  A "calcium and magnesium sequestering agent" is defined as an agent which gives rise to formation of complex negative ions including those metals so as to prevent precipitation of their salts from baths containing compounds which otherwise would insolubilise the alkaline earth metals present, e.g. alkali hexametaphosphates or sulphamates.  The fibres may be bleached by treating them with active chlorine at a pH under 3, then with aqueous alkali hexametaphosphate or sulphamate to which sodium carbonate is added to bring the pH between 10.5 and 11.5, followed by aqueous active chlorine at a pH under 3, and are finally declorinated with aqueous sodium bisulphite at a pH of 8.5.  The preferred temperature range at which all steps may be carried out is 15 DEG  to 25 DEG  C.

Title: Process for preparing a meat analogue
IPC: A23J3/00
Filed: 1976-08-04
Abstract: 1498395 Meat analogue GENERAL FOODS CORP 4 Aug 1976 [6 Aug 1975] 32525/76 Heading A2B A meat analogue is prepared by forming strips of coagulated protein dough by compressing, elongating and heating the aqueous dough and then releasing the compression so that the expansion is less than 20% by volume, soaking the strips in an egg albumenbased binder, assembling the strips with fibres aligned and with substantial absence of voids, and heat-setting the binder. The fibres may be formed in a screw extruder in which a compression chamber is formed between a heated wall and the screw, and which provides a volume reduction of 2-10 times from feed to discharge. The wall may be at 250F or above. The pressure drop on release of compression is preferably such as to limit puffing in the product to 5% volume increase or less. The strips are preferably 0.25 inch thick or less and may be mechanically fibrillated by rolling, which also reduces the thickness if necessary. The strips may be dehydrated to 6% H 2 O content or less if they are to be stored, but in any case are preferably hydrated to about 65% F 2 O by soaking in hot water before further processing. The hot water and binder baths may contain various additives, as may the initial dough. The strips may be soaked in binder for 1-3 hours and then assembled and moulded to shape using only such pressure as is necessary to prevent void formation. The binder may be set by oven or microwave heating. The protein dough may initially contain 20-65% H 2 O. Suitable proteins sources are soy bean meal, peanut meal, cotton seed, oil-extraction vegetable by-products, animal and fish meat, soy isolate, wheat gluten, albumen, dry milk powder, whey, wheat flour, poultry paste, and defatted soy flour. The exemplified dough comprises wheat gluten, ground soy grits. wheat flour, ammonium carbonate and salt.
