Title: Improvements in and relating to Attitude Error Correction Systems for use with a Fuel Gauge
IPC: G01F23/26
Filed: 1967-08-02
Abstract: 1,190,024. Tank gauges. SIMMONDS PRECISION PRODUCTS Inc. 2 Aug., 1967 [26 Oct., 1966], No. 35406/67. Heading G4H. [Also in Division G1] In an aircraft capacitor tank gauge using an automatically rebalanced bridge arrangement, the measurement is corrected for the effects of pitch and roll of the aircraft on the fuel level by supplying one of a preset number of signals to the rebalancing motor dependent on the valve of the pitch, roll and volume of fuel. As shown, the capacitor 9 sensitive to liquid level in tank 9 is connected in a bridge circuit 10 including the secondary winding of transformer 28, capacitors 26, 29, 30 and balancing potentiometer 27 whose order is positioned by motor 32 connected to the output of the bridge via amplifier 31. The capacitor 9 is also common to a second bridge circuit 4, energized with a different frequency whose output is indicative of the volume of liquid and which is connected to an AND/OR matrix 3 to which the digital outputs of pitch and roll sensors are fed via lines 1, 2. Dependent on the combination of signals present one of a number of solid state switches 13-18 will be actuated by the output from the matrix 3, to connect one of a number of capacitors 19-24, connected to the input of amplifiers 31, to transformer 25, to thereby apply a correction to the output from the bridge 10.

Title: Narrow fabrics
IPC: A43C1/00
Filed: 1972-07-29
Abstract: 1430241 Knitting PAREMA LTD 25 July 1973 [29 July 1972] 35599/72 Headings D1C and D1K A narrow warp knitted fabric for use as a tape or shoe-lace includes an elastomer yarn interconnecting spaced wales and knitted under tension so as to bring two parts of the fabric together. In one example, Figure 2A, the ground fabric comprises yarns F2-F6 lapped between adjacent wales and an inlaid weft F8. The elastomer yarn F9 pulls the edge wales W1, W6 together. A core yarn F10 may be included. In a further example (Fig. 4A, not shown), the central yarns have more components than the outer so that the bulk of the wales varies progressively. In the embodiment of Figure 5A, wefts F11, F12 are laid into two halves of the fabric. The yarn F5 joining the two halves may be thinner than the remaining yarns. The elastomer yarn F10 joining wales W2, W7 folds the two halves of the fabric together so as to form a flat fabric. Inlaid warps F13-F18 may be included. A warp machine for knitting the above fabrics include a guide bar 23 for ground yarns and a bar 22 for the elastomer yarn supplied under tension. Guide inserts 26, 27 are mounted on bars 24, 25. Bar 25 is held stationary to feed warp yarns, while 24 is traversed to lay-in wefts. Several fabrics are knit side-byside and taken-up on separate rollers. The fabrics assume their rounded or flattened shape automatically as the elastomer yarn relaxes, as the fabrics leave the needles.

Preferably the cooling rate of the wire after austenitizing does not exceed 3‹C. /sec. in the absence of Cr, Mo, Ti, Nb or V, or 1À5‹C. /sec. in the presence of any of these, to avoid martensite formation.

Abstract: 1,271,838. Smoking machine. IMPERIAL TOBACCO GROUP Ltd. July 6, 1970 [July 18, 1969], No.36256/69. Heading G1B. A smoking machine for testing a cigar 12 or the like comprises a duct 10 connected to a suction device and provided with a smoke detector 20, the smoke detector 20 being arranged to actuate a counter for indicating the number of puffs taken on the cigar 12 when smoke is detected in the duct 10. The detector 20 may comprise a lamp 16 and photo-diode 15 arranged on opposite sides of the duct 10 which itself may be arranged between two pipes 21, 23 having valves 22, 24 which can be actuated to allow a further suction device to clear the duct 10 of smoke between puffs caused by the first mentioned suction device. A radiation sensing device 30 in the form of a further photo-diode may be arranged to indicate when a predetermined portion of the cigar has been burnt away. In use, the detectors 20, 30 are arranged in an electric circuit comprising an AND gate (32), Fig.2 (not shown), the counter (40), a machine control (31), a selector switch (36) and visual or aural warning devices 45, 47 and 50. With the switch (36) inter-connecting the 'length of butt' detector 30 to the AND gate (32) signals are only passed from the AND gate (32) to the counter (40) when smoke is sensed by the detector 20 at each puff of the cigar and while the cigar is long enough for the detector 30 not to be actuated whereby the number of puffs of the cigar 12 before it extinguishes or before the detector 30 is actuated can be determined. With the switch (36) connecting the counter to the AND gate (32) it can be determined whether a cigar under test can be subjected to a predetermined number of puffs as selected on the counter (40).

Filed: 1973-07-31
Abstract: 1420851 Luffing-arm apparatus TOYO UMPANKI CO Ltd 31 July 1973 36470/73 Heading B8H [Also in Divisions F2 and E1] Loading equipment comprises a loading tool 2, such as a fork or shovel, mounted on a lift arm 1 which is pivotally mounted by means of a shaft 11 to the main body 4 of the loading equipment, the arm 1 being capable of being raised and lowered by means of a cam 5, the loading equipment further comprising means for maintaining the loading tool 2 at a desired tilt during raising and lowering of the arm 1. This latter means consists of a piston-rod-cylinder arrangement 63, 6 pivotally connected between the lift arm 1 and main body 4 for sensing the attitude of the lift arm 1, and a second piston-rod-cylinder arrangement 35, 3 for controlling the tilt of the loading tool 2. The piston of the cylinder 6 divides the cylinder into front and rear chambers 62, 61 while the cylinder 3 includes two pistons which divide the cylinder 3 into a front 33, intermediate 32 and rear chamber 31. Both the front chambers 33 and 62 are in fluid communication by means of a conduit 7 while both the rear chambers 31 and 61 are in communication by means of a conduit 8. When the lift arm 1 is raised by means of the ram 5 the piston-rod 63 is caused to retract into its cylinder 6 thereby causing oil to be pushed through conduit 8 into the rear chamber 31 of the cylinder 3 thereby causing a piston 200 and its piston-rod 34 to move forward and mechanically push the second piston of the cylinder 3 and its piston-rod 35 forward, the rod 25 causing the anti-clockwise rotation of the loading tool 2. Conversely, lowering of the arm 1 causes the extension of the rod 63 and thus the transfer of oil through the conduit 7 from the chamber 62 to the chamber 33 thereby causing the retraction of the rod 35 and thus the clockwise rotation of the loading tool 2. Both of the front chambers 33, 62 are in communication with one part A of an oil pressure change-over valve assembly 10 which is in communication with an oil reservoir T. When the valve assembly 10 is shifted to the left in Fig. 6 then pressure oil is supplied through conduit 7 to the chamber 33 causing retraction of the piston-rod 35 and thus the tilting of the tool 2, independently of the operation of the ram 5, the oil in the intermediate chamber 32 of the cylinder 3 being returned via a conduit 9 to the reservoir T, while if the valve assembly is shifted to the right oil is supplied to the intermediate chamber 32 to move the piston-rod 35 forward. The piston 200 includes, at C, an oil leakage compensating mechanism which is shown in detail in Fig. 7 (not shown). The lift arm 1 of Fig. 1 is formed of a single piece, but it may also comprise a first arm member (1a) pivoted to the body (4) and a second arm member (1b) on which the loading tool (2) is mounted, the second arm member (1b) being slidable longitudinally relative to the first arm member (1a), Fig. 2 (not shown).

' With either of these catalysts may be employed substances, such as benzene hydrocarbons and gaseous halogen acids, which facilitate the reaction. The reaction is preferably effected in an inert solvent, such as petroleum ether, benzine, paraffin oil, and com.. pletely-hydrogenated hydrocarbons, e.g. hexahydrobenzene, hexabydrotoluene and decahydronaphthalene. The olefines may be present in the form of oil gas or gaseous mixtures resulting from oil-cracking processes. The temperature of the reaction is 50-200‹ C. and the pressure may be ordinary or super-atmospheric. The products comprise mono- or poly-alkylcarbazoles or their condensation products of an oily or resinous nature. Examples are given of the condensation of carbazole with propylene, butylene and cyclohexene, and of N-ethylcarbazole with propylene. Hexylene is also mentioned as an olefinic reactant.
