Title: Improvement in Blind Flight, Approach and Landing Instruments
Inventor: PRESSIAT ROBERT
IPC: G01S1/02
Filed: 1966-10-13
Abstract: 1,167,012. Aircraft landing instrument. THOMSON CSF. 13 Oct., 1966, No. 45895/66. Heading B7W. [Also in Divisions G2 and G4] An aircraft landing instrument produces an image representing the outline of a runway approached by the aircraft comprising four members 4 . . . 7 defining a trapezium ABCD representing the runway outline from flight information including aircraft altitude, aircraft ground speed, lateral and vertical deviation from an I.L.S. glide path, and aircraft heading, and from the runway length, width and heading and the I.L.S. glide path gradient, the instrument displacing the image laterally as a function of the heading error of the aircraft. The lengths and positions of the sides of the trapezium may be deduced by an analogue computer (see Division G4) the signals from which are fed to servomotors 16, 23, 24, 27, 30 to move the members 4 . . . 7 accordingly. There may be an electromagnet which raises a shield to mask the member 7 after the aircraft has crossed the entry edge of the runway. The runway image is superposed on the pilot's field of view by an optical system (see Division G2) which also superposes lines representing both the actual horizon and the horizon of an infinite horizontal plane, and also points of light to represent where the flight path of the aircraft, if straight, would hit the earth's surface, and also the aircraft positional errors from the ILS glide path.

Title: Apparatus which generates incandescent particles and dust
IPC: A47L9/10
Filed: 1974-10-23
Abstract: 1479180 Preventing fires in filters INDUSTRIAL & MERCHANDISING SERVICES SOC ANON 23 Oct 1974 [25 Oct 1973] 45931/  74 Heading B1T [Also in Division F4] In a shoe repairing machine 1 incorporating an abrasive wheel 3, dust and incandescent particles generated by the wheel 3 are entrained in a stream of air produced by a suction device 6 and conveyed to means for separating the incandescent particles from the dust, the separated incandenscent particles thereafter being extinguished by contact with liquid 10 in a vessel 11. In the embodiment shown in Fig. 1, the mixture of dust and incandescent particles are separated by directing them horizontally through an aperture 8 against the wall of a vertically disposed openended tube 7. The incandescent particles fall downwardly into the liquid 10 and the dust passes upwardly into a filter element 9. The liquid 10 may be water containing a wetting agent such as household detergent. In the alternative embodiment shown in Fig. 3, the dust and incandenscent particles are conveyed by the suction device 6' through a conduit 12 and inlet 15 into a vessel 13 containing liquid 14. A baffle 19, which is located between the inlet 15 and an outlet 16 leading to a dust collector 17 and filter elements 18, ensures that incandescent particles cannot pass directly to the filter elements 18.

[Also in Divisions C2 and C3] A surfactive material is prepared by reacting at least one hydroxy equivalent of a non-ionic surfactant containing at least one hydroxy group, e.g. polyethoxylated (2-50 ethoxy groups) or polypropoxylated C 8-24 monohydric or polyhydric aliphatic or cyclic alcohols, with not more than 4 carboxylic acid equivalents of an unsaturated polycarboxylic acid material or the corresponding sulphonated material obtained by sulphonation across the double bond, the ester thereby obtained being converted to the corresponding sulphonate salt, the said unsaturated polycarboxylic acid material being obtained by a process which comprises pyrolyzing an alkaline earth citrate at a temperature of from 250-400 C. for a period of time until an increase in titrable alkalinity of the reaction mixture is obtained, and converting the unsaturated salt material thereby obtained to the corresponding acid material. The remaining carboxyl groups (if any) are preferably esterified with one or more monohydric or polyhydric alcohols, e.g. C 1-24 monohydric alcohols. If desired some or all of the remaining carboxylic groups may be reacted so that their acid function becomes modified e.g. by conversion to salts (e.g. Na or ammonium), amides or amines. Cleansing compositions containing the surfactive material may be in the form of liquids, gels, emulsions, paste or powders, and may include builders, fillers and optical whiteners. In an example a composition powder comprised 5% of a surfactant according to the invention, 35% Na tripolyphosphate, 20% Na perborate, 7% Na metasilicate, and 15% of Na sulphate; together with trace amounts of optical whitening agents and Na carboxy methyl cellulose. A similar composition contains in addition 2% by weight of a mixture of equal parts of two ethoxylated nonyl phenol. The compositions may contain not more than 10% of a sequestering agent.
Patent GB-477699-A (GB)
Abstract: 477,699. Bomb - dropping sights. OVTSCHINNIKOFF, A. July 9, 1936, No. 19033. Convention date, July 9, 1935. [Classes 9 (ii) and 92 (ii)] A telescope 2, Fig. 1, carries a clock 3 and a mercury level M in a circular channel split on one side into two limbs 10, 11. A contact 5 on the clock is set for a given time determined by speed and altitude. The target is then sighted at a point N and followed by the telescope as it approaches. When the target reaches a point N# giving a certain inclination to the telescope, a contact 13 is closed by the mercury in the level and an electromagnet is energized and starts the clock. After the time for which the clock has been set, the hand 4 of the clock closes the contact 5 when the target is at the point Nalpha and energizes an electromagnet which closes a valve 12 in the limb 10 on one side of the level. This causes the mercury to rise on the other side while the telescope continues to follow the target, ultimately closing a contact 22 to discharge the bomb when the target has reached the correct position N1 or N2 according to altitude. The Specification as open to inspection under Sect. 91 describes also a bomb-dropping device, Fig. 8 (Cancelled), in which a bolt 131 for suspending the bomb is slidable in bearings 132, 132<1> in a bracket 135 supported by a ball-and-socket joint 135<1>. The bracket carries a transverse stem 134 on one side and a rod 137 and sleeve 137<1> on the other side. A barrel 133 fits over the stem 134, and'these several transverse parts are surrounded by an outer cylinder 136 with spacing springs 140, 141. The bolt 131 is attached to the barrel 133. An explosive cartridge 142<1> in the barrel 133 is fired through leads 150 to drop the bomb. The explosion drives the barrel 133 and outer cylinder 136 to the left ; the outer cylinder is first stopped by the sleeve 137<1> ; and the barrel subsequently stopped by a cushioned shoulder 136<1> in the outer cylinder. A hole 144 in the side of the barrel then vents the gases away, and the parts return to the position shown. A side handle is provided to slide the barrel outward for reloading with a fresh cartridge. This subject-matter does not appear in the Specification as accepted.

Abstract: 1,146,067. Photographic silver halide colour development. ILFORD Ltd. Oct. 16, 1967 [Oct.28, 1966], No.48492/66. Heading G2C. Photographic silver halide colour material is colour developed with a colour developer containing alkali-metal sulphite in the presence of a colour coupler and a compound of the formula:- where R 1  is alkyl or 1-6 carbon atoms and R 2  is hydrogen, aminoalkyl, halogen or a sulphonic acid group. Compounds specified are 2-methoxyphenol (i.e. guiacol) and 2-methoxy-4-aminoethyl phenol (i.e. vanillylamine). The coupler and compound may be in the developer or in the emulsion layer or layers of the silver halide material. The compound of the above formula acts as a competing coupler to reduce excessive colour contrast by reacting with oxidized developer to form a dye which is immediately decolourized by the alkalimetal sulphite. The completion of the decolourization is assured by treating the material after development with acid, e.g. with an acid hardening stop bath. The colour material may be a multicolour material having three emulsions sensitized to red, green and blue.
