Title: A continuous wave beacon system
IPC: G01S1/02
Filed: 1955-09-02
Abstract: 774,962. Radio navigation. STANDARD TELEPHONES & CABLES, Ltd. (International Telephone & Telegraph Corporation). Sept. 2, 1955, No. 25286/55. Class 40(7) An omnidirectional radio beacon comprises three radio frequency transmitters generating energy of differing frequencies f 1 , f 2 , and f,. Transmitter 1 feeds aerials at spaced points 4 and 6 to transmit energy over figure-of-eight radiation pattern 7. Energy from transmitter 2 is radiated at 4 and 5 over similar pattern 8 and that from transmitter 3 at 4 and 6 over pattern 9. The patterns are differently orientated, and have no nulls, as shown. They are produced continuously, the frequencies used being of the order of 90 Kc with a small separation between them. Preferably the points 4, 5 and 6 form an equilateral triangle with side lengths of between a quarter and a half of the operating wavelengths, but any suitable aerial arrangement to produce the required arrangement of radiation patterns may be used. As may be seen from inspection of the Figure determination of the relative amplitudes of the three signals from the beacon will give bearing information with a 180 degree ambiguity. The co-operating receiver has an aerial 11 feeding all the signals to a radiofrequency receiver 12 which has a sufficiently wide pass-band to pass the signals to separating filters 13, 14 and 15. Each filter passes the signal of one frequency only and is coupled to one of the stator coils 16, 17 or 18 of resolver 19. The indicator 20 coupled to the rotor indicates the bearing of the receiver relative to the beacon. Specifications 631,172, 641,809 and 763,040 are referred to.

Title: Steam cooker
IPC: A47J27/16
Filed: 1949-10-04
Abstract: 661,453. Steam ovens; sterllizers. DEHN, S. G. (Vendo Co.). Oct. 4, 1949, No. 25508/49. Classes 28 (i) and 81 (i). [Also in Group XIII] A steam cooker comprises a boiler 26 supplying steam to a cooking oven 16 from which condensed steam flows down a conduit and opens a weight closed valve 90 to flow into a small receiving chamber 78, the valve 90 also being manually openable by a coupling from the oven door latching handle 114 so that after cooking, the steam in the oven is first cleared out by allowing it to vent down the same conduit 76 into the chamber 78, before the handle is turned further to open the oven door 112. If a steam pressure arises in the cooking chamber 16 it is released by passing through a filter cup 74 and conduit 76 and moves a lever-weighted valve 90 away from a whistling slit thereby giving an audible warning, so that the operator may adjust the burner 64 by manipulating a valve 68 to lessen the amount of steam passing into the cooking chamber 16. Such steam from 76 thus exhausts into a condensate pan 96. The boiler 26 contains a spaced inner water reservoir 44 of ceramic material with leak openings 52 to the annular intervening space 46 whereby quick evaporation of this limited quantity of water in the space is obtained by the burner 64. The water level in the boiler can be inspected by removing a lid 42 and then viewing the position of a plate 62 supported by a float 58. The hot gases from the burner are confined by the jacket 104 to completely surround the boiler, and also the cooking chamber 16 and then pass through an outlet 108 to a flue 102. In turning the door handle 114 to vent position a cam 125, rod 128, links 134 and 138 and pin 152 moves the valve 90 away from the conduit 76. When the handle 114 is thereafter swung to open position cam 116 and hook 122 are disengaged to permit swing open of the door 112.

Title: Improvements in or relating to metal cleaning
IPC: C25F1/00
Filed: 1928-09-07
Abstract: 324,026. Jones, G. Sept. 7, 1928. Metal polishes consist of a metal electropositive to the metal being cleaned, intimately mixed with a dry moderately strong acid or acid salt which is non-poisonous, non-hygroscopic, and soluble in water, so that on addition of water or application to a wet rag the acid and metal of the mixture react. A water-soluble, non-poisonous, non- hygroscopic neutral salt, an abrasive, and an essential oil or other perfume or substance reacting with any sulphuretted hydrogen liberated may be added. Metals specified are magnesium, zinc, manganese, cadmium, iron, and aluminium. Acid substances specified are citric, tartaric, benzoic, and salicyclic acids, sodium and potassium acid tartrates or citrates, and sodium dihydrogen phosphate. Neutral salts specified are sodium chloride, citrate, tartrate, and sulphate. Infusorial earth or other form of silica is the preferred abrasive. Absorbents of sulphuretted hydrogen are metals or their oxides which form sulphides insoluble in dilute acids, e.g. lead, bismuth, copper, or their oxides. In an example, 100 lb. of sodium acid tartrate is mixed with 13.2 lb. of magnesium and 3.3 lb. of copper oxide, or with 33.3 lb. of zinc and 8.4 lb. of copper oxide. The powders may be packed in substantially air-tight packages. Pastes may be made by addition of a non-aqueous water-soluble vehicle, e.g. glycerine or alcohol. Polishing cloths, papers, or the like may be made by applying to the cloth a mixture of the metal, neutral salt, water, and starch, dextrine, karachi or other water-soluble gum, drying, and then applying a solution of the acidic constituent in alcohol or like solvent.

[Class 97 (i)] Apparatus for reading a straight divided scale comprises an optical system for forming an inverted image of the scale constituting one of two juxtaposed representations of the scale which move in opposite directions when the scale reading changes, the other representation being constituted by the scale itself or by a second scale rigidly connected thereto, or by an erect image of the scale or of a second scale, and a deflector device acting without movement of the scale to bring graduations of the two representations of the scale into coincidence and thereby, by the extent of its movement, to determine the fractional component of the scale reading. In Fig. 1 a movable member A', whose position relatively to a fixed base B is to be measured, is provided with two similar scales A, A<1> on transparent supports A<2>, A<3>. A lens B<1> forms beside the scale A<1> an image with unit magnification of the scale A, and a deviating wedge C, displaceable along the axis of the lens, is inserted in the path of the imaging rays, the wedge having a pointer C<1> moving over a scale C<2> which reads in fractions of the divisions of the scales A, A<1>. The juxtaposed scale representations are observed in a microscope or eyepiece B<3>. Figs. 4 and 5 show a preferred form in which the two observed representations are optical images of a single scale F. The rays forming the two images are separated by an apertured mask G<2> in the focal plane of a field lens G<1>. The images are formed by objectives H, H<1>, the scale lying in the focal plane of the objective H so that the rays are parallel between the objectives. A biprism H<2> and field lens H<3> are disposed in the image plane to form superposed images of the mask apertures G<3>, G<4>.
