Title: Improvements in or relating to navigation training apparatus
IPC: G09B9/26
Filed: 1946-04-30
Abstract: 650,757. Course - recording apparatus. DEHMEL, R. C. April 30, 1946, No. 12998. Convention date, March 27, 1945. [Class 97 (ii)] [Also in Group XL (c)] Training apparatus for simulating the navigation of an aircraft with respect to a radio beacon comprises course recording means wherein motors 1 and 6 are caused to rotate at rates corresponding to the N-S, E-W components of the craft's velocity so that the positions of the lead-screws 3, 8 correspond to the position co-ordinates of the craft and the stylus 177 consequently traces the course of the craft on a chart. Fig. 12 illustrates the apparatus for driving the. motors 1 and 6 which may be mounted in a real craft and operated in accordance with the actual motion thereof, or in a grounded trainer and operated in accordance with its simulated motion. A shaft 120 is rotated in accordance with the real or simulated airspeed of the craft so that the output of potentiometer 122 is proportional to airspeed. This is applied to rotary transformer 123, the shaft of which is set, for example by a gyro-horizon, in accordance with the .rate of climb of the craft so that the output therefrom corresponds to the horizontal and vertical components of airspeed. The vertical component actuates a meter 157 and is also applied through an amplifier 171 to motor 172 which rotates shaft 86 in accordance with the altitude of the craft. The horizontal airspeed component is applied to meter 161 and is also applied to rotary transformer 132, the shaft of which is set according to the heading of the craft and which consequently delivers outputs proportional to N-S and E-W components of airspeed. Windspeed corrections are made by manual adjustment of potentiometer 138 and rotary transformer 144 according to the velocity and direction of the wind. The outputs from 144 are compounded with those from 132 in amplifiers 152 and 153, the outputs of which drive the motors 1 and 6. Specification 627,475 is referred to.

Title: Improvements in or relating to electro-magnetic separation or concentration of minerals
IPC: B03C1/253
Filed: 1923-05-17
Abstract: 224,924. Mordey, W. M. May 17, 1923. Magnetic separators.-In a method of effecting the magnetic separation or concentration of minerals of the type described in Specification 165,822, the material in a finely divided condition is caused to move through an elongated field or fields disposed in the direction of flow of the material and produced by a single phase or multiphase alternating-current system, the responsive material being repelled laterally in opposite directions when the field is produced by a single phase system or laterally in opposite directions, and longitudinally by a field produced by a multiphase system and also in each case in a direction at right angles to the face of the poles. The path of the material may be inclined at such an angle that the material will flow by gravity alone or may be horizontal or nearly so when it is caused to move by shocks or vibrations imparted thereto. The ore &c., usually in the form of pulp, is fed from a hopper d to one end of a relatively long and narrow launder c arranged above the magnet pole a wound with a single coil b traversed by a single phase alternating-current. The launder is made slightly concave or with sides sloping upwards in opposite directions, Fig. 4, the upper surface of the core a being formed to correspond therewith. The core a may be formed of inverted T-shaped stampings or of straight strips of iron as in Fig. 4 or of E-shaped stampings to form three elongated poles. In a modification, the core a which is laminated longitudinally is shaped like a long rack having a succession of vertical poles on its upper side each provided with a multi-phase winding. The strength of the fields may be adjusted by varying the air gap between the poles and the launder or by varying the excitation of the poles. The bottom of the launder may be provided with inclined grooves or riffles extending outwardly and rakes &c. may be suspended in the launder, preferably from fixed supports, to stir up the material and facilitate the separation. The launder may be constituted by the horizontal portion of an endless conveyer. In another modification, Fig. 10. the material from the hopper d provided with a rectangular, curved or circular shaped outlet falls in front of a core a constructed as in Fig. 1 or the modifications referred to above, the responsive material e being repelled in opposite directions and also from the face of the core a, and the inert material f being received in a receptacle i and the material e in a receptacle i<1> which extends partly round the receptacle i.
Patent GB-132858-A (GB)
IPC: G02B5/30
Abstract: 132,858. Matout, L. R. June 28, 1918, [Convention date]. Flash signals.-In signalling by light, the light is circularly polarized in the transmitter, either to the right or left at will, and the receiver is provided with an analyser for circularly polarized light which transmits light polarized in one direction but not the other. Flash signals according to Morse or other code may thus be given, the signals being invisible to anyone not provided with a suitable receiver. Light from a lamp a is rectilinearly polarized by reflection from, or transmission through, a pile of glass plates c or by other means. The light is then circularly polarized by transmission through one or other of two quarterwave plates d, e of mica mounted, for protection, between the sheets of glass. The plates d, e polarize the light in opposite directions, and either may be placed in the path of the beam at will. The receiver comprises a quarter-wave plate f and Nicol prism g. The light may be poarized by a Nicol prism and the quarter-wave plates replaced by Fresnel parallelopipeds. The devices may be in water-tight boxes, so that they may be left on a ship's bridge or conning-tower of a submerging submarine. Instead of the plates d, c, a single plate h may be used, rotated through 90 degrees to polarize the light in either direction at will. Colour signals may be given by interposing a coloured glass in the path of the beam, or by adding, in the receiver, a plate of mica or quartz to produce chrcmatic polarization. In a modification, Fig. 4, to ensure greater secrecy, the light is elliptically polarized in the transmitter by a crystalline plate i, and a similar plate j is provided in the receiver. The plates i, j, which may be of quartz, with optical axes crossed, are of the same optical thickness and oriented so that one neutralizes the effect of the other.

Signal lamps.-In an apparatus for enabling railway-signal lamps to be set in such a position as to ensure that the light from the lamp will be directed so that they can be seen easily by the driver of an approaching train, a sighting-device is mounted so that it is readily attached to, or detachable from, the lamp and fixed so that it is parallel to the central horizontal plane of the lens and the lamp casing. Mounted on the arm c<1> of a post c having a foot c<2> to rest on the base of the lamp casing is a conical cup d provided with a bearing-surface d<1> to fit against the lens and having a tubular ring d<2> of rubber to prevent slipping and scratching of the lens. To adjust the device for different sizes of lamps, a plate h<1> to engage the inner surface of the lamp casing opposite to the lens is mounted on a rod h which screws into the post c and is adjusted in position by wings i<2>. A sighting-tube a is mounted on the top of the post c and comprises a cylindrical casing with an inturned flange a<3> and a central peep-hole a<2>, which may be surrounded by a tubular projection a<6> in which is screwed a tube j closed by a disc j<1> provided with a roughened or milled periphery and a peep-hole j<2>. A plurality of telescoping tubes may be used instead of the tube j<1>, the end tube having a sight-hole. A V-shaped foresight b is mounted on a bar b<1> in the casing a so that the top of the sight is in line with the centre of the peep-hole a<2>. To indicate when the sighting- device is horizontal, and the cap d vertical, a Y-shaped pointer e having an enlarged head e<1> which rests in a bearing f in a slot in the casing a is provided with a pointed end e<3> which moves over a graduated scale g carried by an arm g<1> secured to the post c. The head e<1> is detachable and the slot in which it rests may be enlarged so that it can be withdrawn from the casing. To limit the field of vision, an annular shutter k, Fig. 4, is adjustably mounted in the casing a on a pointer k<3> carried by a screw-threaded rod k<2> operated by a milled or roughened head k<4>. The pointer k<3> moves in a slot in the casing a which is provided with a scale to indicate the angle of vision required. In a modification, the casing a is adjustably mounted in a tube carrying the foresight b. A plurality of telescoping tubes may be inserted between the casing and the tube carrying the foresight.

Title: Improvements relating to the thermal, electrical or other insulation of articles
IPC: H01B3/18
Filed: 1933-05-09
Abstract: An article is insulated electrically, thermally, or against the effects of damp by covering the article with, or by supporting it on, a native or regenerated cellulose which has been esterified beyond the diacyl stage, with retention of its structure, and which is insoluble in organic solvents.  The cellulosic material, which may be in the form of yarn, threads, loose material, fabric, or shaped bodies, may consist of cotton, cellulose pulp, denitrated nitrocellulose, or cellulose obtained by precipitation from viscose or solutions of cellulose in cuprammonium or in quarternary ammonium salts.  Esterification of the cellulosic material may be carried out with acid anhydrides or acid chlorides in the presence, if desired, of acid or alkaline catalysts and diluents, and with or without preliminary swelling of the material.  Suitable esterifying processes are described in Specifications 349,322, 353,978, 379,658, and 380,822.  In examples: (1) electric conductors are insulated by winding on them tapes of cotton or viscose which are propylated beyond the diacyl stage without change of structure; (2) cotton or regenerated cellulose threads are acetylated beyond the diacyl stage, with retention of their structure, and are used as such or in yarn, fabric, or tape form for lagging steam pipes; (3) pipes and cables for underground use are protected against the effects of damp by winding on them cotton bands or regenerated cellulose threads which have been propylated beyond the diacyl stage with retention of their structure.

Title: Improvements in or relating to the treatment of substantially unworn rails
IPC: E01B31/18
Filed: 1934-08-27
Abstract: 437,248. Rails. OXWELD RAILROAD SERVICE CO., 230, North Michigan Boulevard, Chicago, U.S.A.-(Assignees of George, H. S.) Aug. 7, 1934, No. 13552/35. Convention date, Sept. 6, 1933. Divided out of 435,953. [Class 104 (ii)] [See also Group XXII] The tread surfaces at or intermediate the ends of new or substantially uneven rails have surface layers of original metal removed for a length less than three inches and are then built up by deposition thereon of a metal capable of hardening on rapid cooling from an elevated temperature and acquiring a hardness of at least 60 Scleroscope after cold rolling. Large worn areas on rails under service may thus be avoided. The receiving end of a straight track rail joint, on which wear is greatest on the inside edge, has a part 17<1> cut away to a depth of about 0À04- 0À06" and the metal then deposited thereon. The deposit on the inner edge 21<1> may extend for a distance of two inches and on the outer outer edge 23<1> for a distance of half an inch. The rear edge of the deposit is thus diagonal to the rail so that wheels of rolling stock do not abruptly pass from a surface of one hardness to one of a different hardness. The leaving rail 12<1> may have a triangular deposit 18<1> extending half an inch along the inner edge and two inches across the end. For rails which are to be arranged so that more wear occurs from the middle to the outer edges, the shape of the deposits may be reversed. The deposited metal may be an air hardening steel such as an alloy steel containing 0À5 per cent of carbon, 0À9 to 1À1 per cent of manganese 0À9 to 1À1 per cent of chromium, and 0À4 to 0À6 per cent of silicon. The deposition is effected by welding. Rails may also be built up to a greater distance than three inches, in which case the hardness is in consequence reduced. Specification 435,953 is referred to.
