Title: Siliceous pigments
IPC: C08K9/02
Filed: 1956-01-14
Abstract: Siliceous pigments comprise finely divided hydrated silica intimately mixed with a finely-divided alkaline earth metal sulphite.  The pigments may be prepared by mixing a solution of a soluble silicate such as sodium or potassium silicate, a solution of a soluble compound of an alkaline earth metal, such as calcium hydroxide or chloride, and a solution of sulphur dioxide or an acid salt of sulphurous acid such as calcium bisulphite.  The solutions may be mixed in any order and at any temperature from room temperature to boiling-point or even higher if high pressures are used.  A centrifugal pump or a T-junction may be used for mixing.  Preferably vigorous agitation is employed and steam may be blown into the reaction mixture.  When calcium silicate or calcium carbonate is added to the reaction mixture to neutralize it, any excess may remain in the final pigment. Variation of reaction temperature, mixing rate and solution concentration provides some control over the ultimate particle size.  A number of examples are given of three procedures: (A) reacting a silicate with an alkaline earth metal compound, adding an acid sulphite solution then neutralizing to precipitate the mixture of silica and alkaline earth sulphite; (B) reacting an alkali silicate with an acid sulphite solution to precipitate silica, then adding an alkaline earth metal compound at a pH such that the alkaline earth sulphite is precipitated; and (C) forming a slurry of alkaline earth metal compound with an acid sulphite solution and adding an alkali silicate at such a pH that silica and alkaline earth sulphite are precipitated.ALSO:Siliceous pigments comprising finely-divided hydrated silica intimately mixed with a finely-divided alkaline earth metal sulphite, prepared by mixing a solution of a soluble silicate such as sodium or potassium silicate, a solution of a soluble compound of an alkaline earth metal, such as calcium hydroxide or chloride, or barium hydroxide or chloride, and a solution of sulphur dioxide or an acid salt of sulphurous acid such as calcium bisulphite, may be dispersed in natural rubber or synthetic rubber such as butadiene-styrene copolymers (GR-S), butadiene-acrylonitrile, neoprene, isobutylene polymers and copolymers of isobutylene with isoprene, polymers of butadiene, isoprene, piperylene, 2 : 3-dimethyl butadiene, or 2-chlorobutadiene alone or with other ethylenic substances such as acrylonitrile, isobutylene, vinyl chloride, vinyl acetate, styrene, methyl methacrylate, methyl alphachloroacrylate and methyl acrylate. Examples are of compositions containing GR-S rubber, vulcanizing agents and accelerators, and the pigment of the invention, which are compared with similar compositions containing calcium silicate.

Title: Improvements in or relating to road traffic control signalling apparatus
IPC: G08G1/095
Filed: 1930-06-17
Abstract: 354,475. Road signals. BOARDMAN, F. V., Telephone House, Hill Street, Singapore. June 17, 1930, No. 18511. [Class 118 (ii).] A signalling standard for cross roads is so constructed that, to enable traffic to turn right, the clear signal for one road may be changed to the " turn right " signal and the clear signal for the oppositely - moving traffic simultaneously changed to " stop." The standard is rotatable through 90‹ to present the set of changeable signals to the other lines of traffic. In the arrangement shown in Figs. 1 and 2 the hollow pillar 12 supports a fixed drum 13 provided with four orange-coloured apertures 14 controlled by a cylindrical apertured shutter 35 rotatable by a handle 33 to obscure or expose cautionary signals simultaneously. The hollow cross arms 20 .. 23 are mounted on the pillar by means of a tubular support 19 turnable by a handle 24 and are provided with signal windows 31 controlled by spring- urged shutters 38, 39 operated by handles 40, 41 through Bowden wires. In use and assuming the North-South route is open, the windows 31 in the arms 20, 22 present green signals while those given by the other arms are red. If it is desired to permit southward-bound traffic to turn right, the handle 40 is depressed to change to red the signal at 31 on arm 20 facing the traffic and to expose on the other side of the same arm 20 another signal 31 indicating to the southward-bound traffic that it may turn right. Similarly if handle 41 is depressed, instead of handle 40, this traffic is stopped and the reversely-moving traffic permitted to proceed and if desired to turn right. If now the East- West traffic is to be released the handle 33 is lowered and turned to expose the cautionary yellow lights at 14, and this movement of the handle liberates the support 19 to allow its quarter rotation by the handle 24 after which the handle 33 may be restored to lock the support and obscure the cautionary signals. A protecting hood 60 and sign-post directing arms 18 may be provided and the signal apertures may be obscured at any time by shutters such as 61. In a modification suitable for confined places the cross arms may be replaced by a box containing side-by-side lights controlled by vertically movable shutters.

Abstract: 574,670. Rotary filing - machines. DUNLOP RUBBER CO., Ltd., WILLSHAW, H., and GOODHALL, S. N. Sept. 28, 1944, No. 18575. [Class 83 (iii)] In a machine for removing the tread from a tyre by a rotary rasp prior to re-treading, the tyre is mounted on a freely rotatable rim or expanding chuck 5 carried by a cradle 2 suspended by trunnions 3 on a base 1. The rim 5 is mounted on a pin 9 on a slide 4 adjustable transversely to the axis C-C of the trunnions by a screw hand-operated at 7 through bevel gears 11, the inclination of the axis C-C being such that contact of the tyre with a rasp 6 rotated on a stationary horizontal axis by a motor causes the tyre to be rotated about its axis A-A during cutting. Simultaneously, the cradle 2 is swung about its trunnions by a hand wheel 8 and irreversible gearing 10 so that the rasp may operate on one half of the work periphery, after completion of which the work is reversed on its support 5 for operation on the other half. The slide 4 is adjusted so that the circle whose diameter is the mean diameter of the tyre and which lies in the central plane thereof is tangential to the axis C-C. The slide 4 is arranged as close to the floor as possible, to facilitate loading and unloading the work.

Title: Instrument for testing flexible sheet material
IPC: G01N3/20
Filed: 1953-07-03
Abstract: 729,106. Measuring flexibility electrically. JOHNSON & JOHNSON. July 3, 1953 [July 3, 1952], No. 18584/53. Class 40 (1). The flexibility or softness of sheet material, e.g. paper or gauze, is tested by spanning a sheet of the material across an aperture in a base member and measuring the force that must be applied to a second member to push the material through the aperture to form a loop. Machine construction, Figs. 2, 3. The sheet material under test is carried on a table 26 and adapted to be pressed through a slot 25 in the table by a blade 23-24 carried at the end of a rocking beam 18. The beam, adjustably counterweighted at 28, is pivoted at 16 to a U-shaped yoke 14 itself coaxially pivoted at 13, 15 in frame members 11. The yoke carries a plate 29 on which is mounted a resistor-type strain gauge 30 comprising four resistor elements arranged to be strained differentially in pairs through a stem 31 extending through and secured to the beam 18 by a nut 33. The yoke also has an arm 35 weighted at 62 so as to bear on an eccentric 36 rotated by an electric motor 37 through one revolution at each measuring operation. The anticlockwise movement of the beam due to the weight 62 varies the strain on the stem 31 in accordance with the force required to press the sheet to form a loop in the table aperture 25. Measuring and calibration, Fig. 5. The four resistors of the strain gauge 30 are connected to form a bridge circuit 49 fed through a rectifier 54. The bridge is balanced with a mass 59 of say 40 gms. removably mounted on the blade 23, by adjustment of the counterweight 28. The mass 59 is now removed and the rheostat 53 adjusted until the microammeter 50 reads 40 microamps. The mass 59 is now replaced and the meter is now calibrated to read in microamps the force in gms. exerted on the blade 23 by the sheet. In operation, with switch 43-44 closed, a switch 40 is momentarily closed to energize the motor, which mechanically closes a spring-biased switch 41 to maintain the motor circuit until the eccentric 36 has completed one revolution. The meter deflection is then indicative of the softness or flexibility of the material under test.

Title: Benzo(a)quinolizine derivatives and their preparation
Inventor: OPENSHAW HARRY TACON
IPC: C07D455/06
Filed: 1960-05-27
Abstract: An optically active enantiomer of 3-ethyl-1,2,3,4,6,7 - hexahydro - 9,10 - dimethoxy - 2 -oxo - 11bH - benzo(a)quinolizine is racemized by heating with an acid in a solvent, thereby causing a simultaneous epimerization at both C3 and C11b.  The process is applicable for the preparation of salts of an optically active enantiomer with an optically active camphor-10-sulphonic acid.  Thus (+) - 3 - ethyl - 1,2,3,4,6,7 - hexahydro - 9,10 - dimethoxy - 2 - oxo-11bH-benzoquinolizine is racemized by heating it with (-)-camphor-10-sulphonic acid substantially equivalent to the total amount of ketone present in a solvent in which the (-) - camphor - 10 - sulphonate of the (-)-enantiomer is the least soluble component and separates from it, while the salt of the (+)-exantiomer remains in solution and undergoes racemization. The process is similarly applicable to the (-)-enantiomer of the benzo(a)-quinolizine by use of (+)-camphor-10-sulphonic acid.  The preferred solvent is ethyl acetate, and the free bases may be isolated from the optically active salts by treatment with aqueous ammonia.  Specifications 999,091, 999,092 and 999,096 are referred to.
