Title: Automatic braking systems for aircraft
Inventor: PENDLEBURY JOHN ALLEN
IPC: B64C25/46
Filed: 1953-07-17
Abstract: 737,148. Fluid-pressure brakes. DUNLOP RUBBER CO., Ltd. July 1, 1954 [July 17, 1953], No. 19822/53. Class 103 (1). In aircraft automatic braking systems, particularly for aircraft having undercarriages comprising two or more landing wheels coupled together on a single strut, e.g. a twin-wheel or bogie type undercarriage, an automatic braking apparatus is associated with each wheel, in conjunction with the fluid pressure operated brakes, for governing the braking pressure in accordance with the rate of change of angular velocity of the wheel wherein the apparatus are connected together in such a manner that automatic release of braking pressure from one wheel releases it from the other wheel. In the embodiment shown, the inlet nozzle 30 of an automatic braking apparatus of the rotary inertia type described in Specification 676,708, associated with the port landing wheel 1 of an aircraft is connected to a source of fluid pressure. One outlet nozzle 28a is blanked off and the outlet nozzle 28 is connected to the inlet nozzle 30 of the apparatus associated with the starboard landing wheel 2. One outlet nozzle 28 of the apparatus associated with the starboard wheel 2 is connected to the brake operating mechanisms, supported by torque plate 5, associated with that wheel, whilst the other starboard nozzle 28 is connected to the brake operating mechanisms associated with the port wheel 1. The exhaust nozzles 32 of both port and starboard apparatus are connected to a reservoir. In operation, should one wheel of the pair tend to skid or slide, the braking pressure to both wheels will be relieved simultaneously; thus avoiding any undesirable couple on the undercarriage strut. Specifications 625,726 and 676,708 are referred to.

Abstract: 153,391. Perl, A. H. F. Aug. 12, 1919. Splitting.-A hand-operated machine, stated to be applicable for cutting wood among other uses, consists of two frames hinged together and carrying co-operating shear blades, arranged to rest by rollers on a bench, table, &c. When pressure is put on one of the frames which serves as a table for the material to be cut, the jaws of the blades close up and effect the cut. The line of the cut may be at right-angles or at an acute angle to the plane of the table. Fig. 1 shows the machine for cutting at right-angles. The table 3 having a blade 1 at the end is hinged to the frame 9, 10 which rests by rollers 26, 27 on a bench or table. The frame 5 which carries the co-operating blade 4 is also hinged to the frame 9, 10 and rests by rollers 13, 14 on the bench &c. The table 3 and frame 5 are kept in normal position by springs 7 and 30. Stops 24, 25 limit the upward and downward movements. The machine is brought into action by pressure on the table 3. In Fig. 5 the machine is shown adapted to cut at a bevel. The frame 5 is cranked upwards to carry the knife 4 at an acute angle to the plane of the table 3, the rest of the parts being correspondingly modified. The brackets 18, 19 are slotted to allow adjustment of the angle of the cut.

Title: Apparatus for locking telescoping tubular members
IPC: F16L21/08
Filed: 1976-05-14
Abstract: 1535090 Telescopic pipe couplings HYDROTECH INTERNATIONAL Inc 14 May 1976 [10 June 1975] 20034/76 Heading F2G A pipe coupling for mutually telescoping tubular members 12 and 4 comprises a plurality of serrated gripping elements 8 which are radially movable to grip and bite into the outer surface of tubular member 12 by relative movement of surfaces 14 and 16 on thrust member 18 and cam member 22 respectively. As shown in Fig. 1 gripping elements 8 are retained against surfaces 14 and 16 by means of shear pins 34. On tightening nuts 52 axial movement of thrust member 18 occurs via annular piston 40 and annular sealing rings 54. The axial movement of thrust member 18 and hence surface 14 causes shearing of pins 34 and radially inward movement of cams 6 and hence surface 16. Gripping elements 8 are thus urged radially against pipe 12 by thrust member 18 and cams 6. The outer serrated surface of thrust member 18 bites into the interior surface 38 of tubular member 4. Locking member 62 screwed to annular piston 40 prevents relative movement of tubular members 4 and 12. The part 60 provided enables the fluid tightness of the joint to be tested.

Abstract: 617,985. Roller sheeting machines. FERGUSON & SONS, Ltd., J., and EDE, S. A. July 4, 1946, No. 20053. [Class 87 (ii)] [Also in Group II] The rolls 1, 2 of a mill for forming sheets of plastic material operate at different speeds in opposite directions, and at one end of the nip between them the material is fed from a hopper 4 on to the slower roll 2 and is carried round on the roll 1 until it rides over a stripping knife 7 arranged along the roll 1 and is deflected at the feeding end by a deflector 13 so that it moves laterally from the feeding end to the stripping end, being carried round by the roll 1 and passing repeatedly through the nip. At the opposite end a stripping knife 10, assisted by a wheel cutter 12, removes the material in a band 9a. The stripping knives 7 and 10 are held against the roll 1 by weights (not shown). The hopper may be mounted on a vibratory device 4a. A suitable operating temperature is maintained by steam-heating the roll 2 and watercooling the faster roll 1 to counteract the greater effect on the latter of the friction between the rolls. Mention is made of feeding a powdered phenol formaldehyde resin and filler on the centre of a pair of differentially rotating rolls, by which a sheet is formed which travels towards both ends of the rolls. Combined Intelligence Objectives Sub-committee report is referred to, and mentions a method (items 9 and 20, p. 182) according to which a powdered phenol formaldehyde resin and filler are fed on to the centre of a pair of differentially rotating rolls, whereby a sheet is formed, builds up and travels towards the ends of the faster roll and is cut off continuously by two wheel cutting knives and two stripping knives.

Title: Improvements in or relating to apparatus for supplying liquid fuel to burner units
IPC: F23K5/02
Filed: 1958-06-24
Abstract: 859,969. Regulating liquid levels. WOOD, A. W. June 18, 1959 [June 24, 1958], No. 20220/58. Class 123(1) [Also in Groups XI, XXVIII and XXIX] A constant level 34 is maintained in the oil reservoir 11 of a burner by a float valve 27 which controls the flow of fuel into the reservoir. from a diaphragm pump 19 and which comprises a ball 28 on the end of a spindle 29 provided with a float 33. On the suction stroke of the pump oil is drawn from a storage tank 13 through a non-return valve 21 therein and the ball 28 engages its seat 30 to prevent withdrawal of oil from the reservoir 11. On the pressure stroke of the pump the ball 28 is lifted off its seat 30 and oil enters the reservoir 11. When the oil level in the reservoir 11 is above the level 34 the ball 29 is held above its seat 30 by the float and the suction stroke of the pump therefore withdraws oil from the reservoir. A further seat may be provided above the ball so that the ball when raised prevents the oil from entering the reservoir.

Title: Improvements in and relating to the production of alimentary salt
IPC: C01D3/06
Filed: 1929-07-05
Abstract: 319,203. Woog, P. Sept. 17, 1928, [Convention date]. Table salt preparations. - An elementary salt preparation is obtained by extracting, without substantial chemical alteration, the salts contained in sea water. The sea water, freshly collected and preferably filtered, may be concentrated by heating the material during which the magnesium sulphate reacts with sodium chloride to give magnesium chloride. Concentration, which is carried to the point at which the salts commence, to separate in crystalline form, may also be obtained in the pools of salt marshes or by electric osmosis or by extracting the pure water by freezing. The pulp obtained is further concentrated to a pasty mass or to a dry powder by continuing the evaporation as rapidly as possible by heating to a temperature, not exceeding 105‹ C., just sufficient to maintain evaporation without superheating the mass, agitation being simultaneously employed. The dry material may be ground, producing a homogeneous mixture, and may then be desiccated further. Magnesium oxychloride is formed in the concentration but the process is regulated by employing controlled heating, by carrying out the final evaporation as rapidly as possible, and, if desired, by .employing artificial draught to reduce this decomposition to a minimum. Concentration mav be carried out in a vacuum, and in several stages, the vapour from one stage being used for heating in the succeeding stage. The final desiccation may also be carried out in a vacuum, the material being disposed on shelves in the container. Concentration may also be effected by atomization in a hot atmosphere or by using hot rotating drums which dip into the solution and which have scrapers for removing the pellicle of dry salts. The material may be stoned in closed vessels. In some cases the material may be disposed at ordinary or low temperature in an atmosphere charged with water vapour in order that the salts may be rehydrated to a desired extent. The apparatus for concentration and desiccation may be placed on a boat which may collect pure water in the open sea. The material may be used in place of ordinary salt in human and animal food.
