Title: Improvements in or relating to diagnostic compositions and methods for employing same
IPC: G01N33/94
Filed: 1943-04-09
Abstract: A dry solid composition for use in estimating amino-arylsulphonamides comprises citric or tartaric acid, a salt of a p-dialkylaminobenzaldehyde with a non-oxidizing inorganic acid, and a water-soluble blue dyestuff.  The composition, preferably in tablet form, on addition to urine, deproteinized blood, cerebro-spinal fluid, milk or the like containing amino-arylsulphonamides produces a green-colouration, due to the formation of a deep yellow-coloured schiff base by reaction between the dialkylaminobenzaldehyde and the aminoarylsulphonamide, which can be compared with predetermined standard colours.  p-Dimethylaminobenzaldehyde or p-diethylamino-benzaldehyde may be dissolved in sulphuric, hydrochloric or phosphoric acids, the product being titurated with citric or tartaric acid and a water-soluble blue dye such as Methylene blue, Wright's stain, Patent blue, Victoria blue, Indulin, Meldola's blue, New blue, Alizarin saphirole or Indigo Carmine blue in the presence of water and/or alcohol, and dried. The products may be mixed with sodium carbonate and an excipient such as lactose and compressed into tablets.  Ammonium and alkali metal bisulphates and urea sulphate and hydrochloride are also referred to as solvents which react with p-dialkyl-aminobenzaldehydes to produce inorganic salts thereof.

Title: Improvements in the preparation of anhydrous normally-liquid ethers for use more particularly in the production of silicone intermediates
IPC: C07F7/12
Filed: 1946-02-25
Abstract: Anhydrous normally-liquid ethers are prepared from "wet" ethers by adding sufficient silicon tetrachloride to react with the water present.  If the ether is used for preparing Grignard reagents, any precipitate which settles out should be filtered off.  Excess silicon tetrachloride is permissible if the Grignard compound is to be used for preparing alkyl, aryl, or aralkyl silicon halides, e.g. as intermediates for silicone resins. Examples describe the reaction of silicon tetrachloride with wet ether, and the use of the ether in the preparation of ethyl magnesium bromide when the precipitate had been separated, and also when the precipitate was not removed, but did not settle.  A further example describes a failure to prepare ethyl magnesium bromide when ether containing a precipitate which settled was used.

Title: Improvements in and relating to hydraulically operated clutches
IPC: F16D43/284
Filed: 1947-03-04
Abstract: 628,499. Friction clutches. HOBBS TRANSMISSION, Ltd., and HOBBS, H. F. March 4, 1947, No. 6143. [Class 80 (ii)] In a clutch of the kind in which a driven disc 17 is frictionally clamped against a driving flywheel 10 by oil-pressure in a space 22 in the flywheel acting on a presser-plate 18 through a diaphragm 20 (or pistons) and an insulator-plate 19, pressure in the diaphragm-space 22 is controlled by a centrifugally-operated spring-pressed piston exhausting valve 46 sliding in the rotary driving member 10 in a cylinder the outer end 43 of which, in the innermost position of the valve 46, communicates with an oil-duct, such as, e.g. the diaphragm-space 22 through a port 59, which communication is closed in outer positions except for a working pistonclearance or leak-opening through which oil trapped at the end of the piston must leak either to the pressure-space or alternatively to exhaust as the piston 46 moves outwards. The inner end of the piston 46 has ports 48 which, in the inner idling position, exhaust the diaphragm-space 22 at 51 to disengage the clutch, and the slow leak of the trapped oil at the outer end retards valve-movement in both directions giving gradual engagement and disengagement at low speeds without hunting. Oil is supplied to the diaphragm-space 22 by a pump 25 through a manual valve 26 and a second sliding piston-valve 40, which centrifugally balances the mass of oil in a radial duct 32 leading the pump-supply to its outer face, and is forced inwards against spring-pressure by the pump-pressure to shut off a port 34 exhausting the diaphragm-space at 41 and supply the space with pump-pressure. Closure of the valve 26 thus exhausts the diaphragm-space at 41 for manual declutching at any speed, whilst with the manual valve 26 open clutch engagement will not occur below the predetermined speed at which the centrifugal valve 46 opens the exhaust-port 48, preventing the build-up of sufficient engaging pressure by the pump. A modification (Fig. 4, not shown) of the centrifugal valve 46 supplies oil to the trapped outer space 43 through a central duct in the piston leading to its inner end. The friction surfaces operate lubricated. Specification 628,523 is referred to. The Provisional Specification states also that the centrifugal-valve exhaust is so situated in relation to the diaphragmchamber as to maintain the latter full during automatic disengagement, so that subsequent re-engagement is not too sluggish. Specification 596,908 also is referred to in the Provisional Specification.

A spring-winding machine for the manufacture of coil springs with tangential straight ends 8 by means of a winding tool 7 which is brought into the winding position by a rotating cam disc 9 and by a control lever 10 supported on the periphery of such disc and is brought back from such position by spring means 21, under control of the cam disc 9, is characterized in that on the control lever 10 and rotatable around a pivot axis 31 parallel to the axis M of rotation of the cam disc 9, a supporting lever 30 is mounted in such a way that as long as it is supported with its free end on the cam periphery, against a stop 36 arranged on the control lever 10 its contact point on the cam disc 9 lies behind the plane passing through the axis M of rotation of the cam disc and of its own pivot axis 31 by an amount in the direction of rotation of the cam disc 9 only just sufficient to maintain stable contact with that disc. The tool 7 is thus moved, by the spring 21, smartly away from the coiling position when an axle 35 on the lever 30 and bearing on the cam-disc 9 reaches a sharp step 15 on the cam. A tangential spring end 8 is thus properly formed as wire 1 continues to be fed by rollers 2, 3. The lever 10 drops on to a stop 37 with the lever 30 out of contact with the recessed part 13 of the cam 9. The wire 1 is severed from the supply by a cutter 38.
