Filed: 1953-10-21
Abstract: A pigment composition comprising at least one water-insoluble polyvalent metal salt of at least one high polymer of an unsaturated carboxylic acid and intimately dispersed therein at least one basic dyestuff is made by adding a water-soluble salt of a polyvalent metal to a solution containing a basic dyestuff and a salt of a monovalent metal, or of a nitrogenous base of the high polymer, and removing the precipitate which may then be dried and ground.  High polymers mentioned are polyacrylic acid, polymethacrylic acid, and copolymers of acrylic acid, methacrylic acid, or maleic acid with styrene, acrylonitrile, vinyl ethers, vinyl chloride, vinyl carbazole, isobutylene, butadiene, chloroprene, or acrylic or methacrylic acid esters.  The polyvalent metal may be aluminium, magnesium, calcium, strontium, zinc, titanium, zirconium, or tin.  The monovalent metal may be sodium and the nitrogenous base ammonia or triethanolamine. The dissolution of the polymer in water may be assisted by the addition of alcohol or acetone.  The dye may fluoresce in the daylight.  Rhodamine B and Rhodamine 6J are the exemplified dyes.

Abstract: 601,638. Spring buffers for railway vehicles. MARSH, J. W. Nov. 2, 1945, Nos. 29211 and 29212. Convention dates, Nov. 9, 1944, and Nov. 25, 1944. [Class 103 (v)] A buffer for railway cars comprises a plunger 13 carrying a head 12 and retained in a housing 1 by radial lugs 5 on the casing which engage lugs 14, 15, 16 on the plunger. The plunger is prevented from rotating (which would permit the lugs 14, 15, 16 to pass between the lugs 5) by a key member 18 which comprises a base portion 19 which engages the end plate 2 of the housing by means preventing rotation of the key member 18, and keys 22, 23 which fit between the lugs 14, 15, 16 on the plunger 13. A spring 24 urges the plunger 13 out of the housing 1 and also presses the base 19 of the key member 18 into engagement with the end plate 2 of the housing. As shown, the base 19 of the key member 18 has an apertured polygonal spigot 17 which is received within a polygonal opening 3 in the end plate 2. In an alternative construction, the base 19 and the end plate 2 are formed with co-operating ridges and depressions so that the pressure of the spring 24 prevents the key member 18 from rotating relatively to the housing. To dis-assemble the buffer shown, the key member 18 is pressed from the rear into the housing 1 and out of engagement with the end plate 2. The plunger 13 and key member 18 may then be rotated together until the lugs 14, 15, 16 will pass between the lugs 5.

Abstract: 1,070,292. Aerials. RHEINMETALL G.m.b.H. July 17, 1964, No. 29271/64. Heading H4A. In an aerial system such as a radio telescope comprising a large dish type reflector, a vertical support shaft 8 is carried on bearings in a casing 9 upon which is mounted an azimuth drive motor connected to the shaft by a pinion and ring wheel gear train. The casing has a spherical seating A, of radius R, in a main housing 10, and may be rotated thereupon for adjustment purposes by two sets of slides 3, 4 at right angles to each other. In this way, the shaft 8 may be brought into a truly vertical position should the housing 10 be tilted by, for example, subsidence of the earth. Rotation of the casing 9 in reaction to the azimuth drive may be prevented by a mechanical linkage to the housing 10 or by a magnetic lock. The actuation of the adjustment slides may be effected automatically under the control of a separate pendulum device or the slides may be dispensed with if the centre of gravity of the system is made sufficiently below the centre of the spherical seating A. In a second'embodiment, Fig..4 (not shown), the spherical seating is inverted and is located at the bottom of the casing, the adjusting slides then being arranged between the upper ends of the casing and the housing. The casing may be provided with flanges (F1) and the housing with flanges (F2) and they may be bolted together after adjustment of the slides, distance pieces (D) being interposed if required. In a third embodiment, Fig. 5 (not shown), an azimuth drive motor (5) is mounted on a fixed support structure on which is also mounted a cup for a spherically seated housing (15). The main shaft (1<SP>1</SP>) of the radio telescope is carried on bearings in the housing (15). A ring gear-wheel (14) surrounding and secured to the shaft (1<SP>1</SP>) meshes with a pinion (13) carried in the housing (15), said pinion being driven by the motor (5) through a universal joint shaft (12). Packing pieces (16) are placed under the motor (5) to ensure that its shaft is parallel with the main shaft (1<SP>1</SP>).

Abstract: 533,411. Agricultural tractors. INTERNATIONAL HARVESTER CO. Nov. 6, 1939, No. 29443. Convention date, Nov. 25, 1938. [Classes 79 (i), 79 (iv) and 79 (v)] A tractor in which the front and rear wheels are spaced apart laterally to straddle a row of plants has a frame structure 14 the whole or part of which is offset laterally with respect to the centre line of the tractor so that the driver can see the plant row from his seat 33 at the rear of the tractor. In the construction shown the seat 33 is offset on the off side of the tractor and balances to some extent the engine 10, clutch 13, frame 14 and change speed gearing 18 on the near side. The frame and axles are arranged at a high level as shown and the axles have downward extensions at their ends to the wheel axles. The rear or driving axle comprises a differential gear casing provided with a lateral tubular extension 20, the ends of this axle having vertical extension casings 21, 24 enclosing gearing driving the wheel axles 22. The front axle comprises a main tubular member 41 connected to a steering gear bracket 36 on the frame by a longitudinal pivot 39 to allow the axle to oscillate in a vertical transverse plane. The outer ends 42 of the axle slide in the tube 41 to vary the track width of the front wheels and are secured by clamps 43. Vertical tubular extensions 44 of the axle ends 42 form housings for steering pivots 45 of the wheel stub axles 46. The steering shaft 51 controls the stub axles through an arm 50 on the steering gear 36, transverse adjustable links 49 and arms 48 on the steering spindles 45. The driving wheels 23 have offset hubs so that their track width can be adjusted by reversing them on their axles 22.

Patent GB-603937-A (GB)
Title: Improvements in or relating to light signal apparatus for light buoys and the like
IPC: B63B22/16
Filed: 1945-11-06
Abstract: 603,937. Visible signalling-apparatus. GAS ACCUMULATOR CO. (UNITED KINGDOM), Ltd., and DORTON, E. W. Nov. 6, 1945, No. 29537. [Class 118 (ii)] The invention comprises modifications of group-flashing apparatus of the kind comprising a gas chamber closed by a diaphragm, an outlet valve to a gas burner controlled by a pivoted tongue located within the chamber and actuated by the diaphragm through a connection adapted to provide lost motion of the diaphragm between the opening and closing movements of the tongue and an auxiliary gas inlet valve cyclically operated by means of a coding wheel driven by pawl and ratchet mechanism of which the pawl derives its movement from the said diaphragm. The tongue 7 which is mounted on pivots 8 carries a spindle 21 on which are mounted a ratchet wheel 22 and a code wheel 23 associated with the auxiliary valve 18 providing an additional inlet to the chamber 1 from the supply pipe 15. The operating pawl 26 for the ratchet 22 is carried by an arm 24 pivoted at 25 and provided with a projection 29 located in line with an adjustable pin 5 carried by the diaphragm 2 loaded by the spring 3. A hook 6 secured to the tongue 7 has its lower end opposite the projection 29 and positioned within a loop 4 secured to the diaphragm 2. When gas passes to the chamber 1 through the main inlet which is provided with an adjustable throttle 16, the diaphragm 2 is moved downwardly and the arm 24 follows under the action of a spring 28 until arrested by the stop 31 and moves the pawl 26 idly over one tooth of the ratchet 22. By the continued movement of the diaphragm the top portion of the loop 4 engages the hook 6 and withdraws the tongue 7 from its seat 10 at the bottom of the outlet tube leading. to the burner 12. As the pressure of the gas chamber decreases the diaphragm moves upwardly and the engagment of the pin 5 with the projection 29 moves the arm 24 and pawl upwardly to rotate the ratchet 22 and code wheel 23 through one step bringing, as shown in Fig. 2, a projection 37 beneath the stem of the auxiliary valve 18. During the final portion of the upward movement of the arm 24 the projection 29 engages the bottom of the hook 6 lifting the tongue 7 to a position in which it snaps on to the valve seat 10, for example, by magnetic action and causes the projection 37 on the code wheel 23 to open the auxiliary inlet to shorten the period between flashes. The code wheel may be shaped to provide for groups of flashes in which the interval between the flashes varies from one group to another.

Title: Process for the production of hydrogen peroxide
IPC: C01B15/023
Filed: 1976-07-20
Abstract: In the production of hydrogen peroxide according to the anthraquinone process, the dissolution of the alkylanthrahydroquinones used as starting material is effected by employing a mixture of at least two solvents of different substance types. By virtue of the solvent mixture, a high capacity of the working solution is achieved, and at the same time a distribution coefficient with respect to aqueous hydrogen peroxide obtains which permits entirely safe operation in the oxidation stage. The process enables the production of hydrogen peroxide of high quality combined with high operational safety without problems in the hydrogenation, oxidation and extraction stages.
