Patent GB-604224-A (GB)
Title: Gyro erection system
IPC: G01C19/44
Filed: 1945-08-20
Abstract: 604,224. Gyroscopes. BENDIX AVIATION CORPORATION. Aug. 20, 1945, No. 21283. Convention date, Sept. 18, 1944. [Class 97 (iii)] In the type of erecting mechanism for gyroscopes having a rotatable frame 22 driven from the gyro rotor provided with a counterweight, such as the ball 31, movable relative to the frame in a restricted arcuate path, there is also provided a second counterweight 43 lighter than the ball and carried, by the frame at a position in which its extremity more remote from the movable counterweight is positioned substantially diametrically opposite the trailing edge of said arcuate path and leads the movable counterweight by an angle of more than 90 degrees but less than 180 degrees. The ball 31 is carried round in the stationary groove 30 between limits formed by the roller 33 and an arm 32 on the frame 22. The frame may be driven by magnetic drag between the magnet 18 and the cup 19 and its speed is maintained substantially constant by an escapement mechanism comprising a starwheel 35 turned by a pinion 41 engaging a fixed gear wheel 42. An escapement lever 40 cooperates with the star-wheel. The second counterweight 43 is rigidly but adjustably fixed to the frame. Alternatively the carriage may be driven by a friction slip-drive from a cylinder on the rotor spindle. The effect of the two counterweights and the pendulosity is to produce an average torque substantially normal to the plane of the axis of rotation of the gyroscope and the dynamic vertical at various angles of tilt giving a substantially linear erection with little or no precession. Specifications 441,439 and 603,158 are referred to.

Title: Improved method of obtaining coal powder by froth flotation
IPC: B03D1/14
Filed: 1936-08-01
Abstract: 460,761. Washing coal. BIESEL, P. Aug. 1, 1936, No. 21327. [Class 82 (ii)] Coal powder with an ash content of less than 1 per cent is obtained from coal already poor in ash, e.g. with an ash content of 2-5 per cent, by froth flotation. The apparatus comprises a unitary structure divided into a plurality of compartments each comprising an agitating cell and a separating cell, or groups of agitating cells and separating cells. Tailings are withdrawn from each agitating cell or group of agitating cells and the coal froth floating in the separating cell or cells in each compartment is passed to the agitating cell or cells of the next compartment. Fresh water is supplied to the agitating cell or cells of each compartment. The apparatus shown includes nine units 1 . . . 9, each being divided into an agitating cell a and a separating cell b, which communicate through an opening c. The units 1 and 2 form a single compartment and the other units are separated from-one another, each constituting a compartment. The coal is introduced at d and the froth forming in the separating cells b of the first compartment passes into a trough f from which it is raised by a conveyer k to a shoot k1 which leads it to the agitating cell a of the unit 3. The treatment is repeated in each compartment, tailings being removed from each cell a by pipes h leading to a collecting pipe h1, and the purified coal being collected at g. To facilitate the removal of the coal froth, the separating cells b may be provided with a horizontal or inclined false bottom m, Fig. 3, the passage of the froth over the member m being assisted by blade wheels o or a rake conveyer o1. The flotation agents preferably comprise an oil such as beach tar oil and an alkali, e.g. ammonia. The purified coal may be used in the manufacture of electrodes, for driving coal-dust motors, for the production of emulsions or suspensions of coal in oil, &c.

Title: Improvements in and relating to air conditioning apparatus
IPC: F24F1/0035
Filed: 1935-07-27
Abstract: 438,784. Conditioning air. BRITISH THOMSON - HOUSTON CO., Ltd., Crown House, Aldwych, London. July 27, 1935, No. 21414. Convention date, July 27, 1934. [Class 137] An air-conditioning unit for heating, or cooling, moistening and filtering air comprises inner and outer casings 10, 30 and fans 12 for circulating air through the casings, and discharging the conditioned air through outlets 19, the air being discharged upwardly when cold, but downwardly when hot due to adjustment of directional louvres 65. The outer casing may be easily removed to expose and allow access to the components in the inner casing. Fresh air enters through a duct 26 and recirculated air through louvres at the side of the unit, and these are mixed in a chamber 30<a>, filters 23, 22 being provided for the incoming air. Fans 12 driven by a motor 13 blow the air through conduit 17<a> and into contact with heating coils 44, a moistening bath 60, and cooling coils 47, the conditioned air escaping through the adjustable louvres 65. When the air is to be cooled, and the coils 44 are not operating, the louvres 65 direct the air upwardly. When heating takes place, a thermostat causes the louvres 65 to be operated so that the warm air is directed downwardly. This thermostat may comprise a bellows, Fig. 4, which, on expansion due to heat, presses upwardly a link 72 pivoted at 75 against the action of a spring 79 until the link engages a stop 88, and the pivot 76 passes over the centre of a spring 83 which snaps a link 73 downwardly against a stop 89, and rotates the louvres about their pivots 66, due to movement of a bar 68 by which they are linked together. A control knob 39, by a shaft 40 and link 41, operates a damper 37 in the fresh air supply, and adjusts the proportion of fresh air to recirculated air. The supply of heating or cooling fluid is controlled by thermostats responsive to the temperature of the room. The height of the inner casing above the floor may be adjusted by turning screw-threaded portions of the legs 11, and that of the outer casing by its being mounted on stacked channel strips 36 to the desired number.

Title: Improvements in and relating to synthetic resins and the process of making same
IPC: C08G8/28
Filed: 1922-08-11
Abstract: Synthetic resins are produced by condensing a phenolic body with carbohydrates, preferably polyoses, and subsequently incorporating a methylene hardening agent, the mixture being subjected to heat or heat and pressure.  Suitable raw materials are wood, sawdust, wood flour, scrap paper, rice and oat hulls, corn cob cellulose, bagasse fibres, cotton linters and waste, gum arabic, cherry gum, dextrine, starch, cane sugar, vegetable ivory nut &c.  The phenolic bodies specified are phenol, cresol, resorcinol, naphthol or their homologues, and suitable methylene hardening agents are formaldehyde, hexamethylenetetramine, furfuramide, methyl furfuramide, hexamethylene triphenol, the aniline hydrochloride condensation product with formaldehyde, and the double compounds of hexamethylenetetramine.  The process may be carried out with the aid of catalysts and the products are potentially reactive or insoluble and infusible according to the degree of treatment.  Examples show the condensation of phenol with sawdust using sulphuric acid as catalyst, with or without the neutralization of the catalyst before the addition of formaldehyde or, if an anhydrous reaction is desired, of hexamethylenetetramine, paraformaldehyde or furfuramide. Hydrochloric acid is also specified as a catalyst.  Fillers, pigments, colours, or lubricants may be incorporated with the resins at any stage of the reactions.  Specifications 102,751 and 171,729 are referred to.
