Title: Manufacture of vat dyestuffs
IPC: C09B5/40
Filed: 1945-09-24
Abstract: (1) 5 - Amino - 1 - (Bz.1 - benzanthronyl) amino-anthraquinone or (2) its alkaline condensation product is heated with an acylating agent which introduces the residue of an o-halogen-benzene monocarboxylic acid, and the product of (1) is then treated with an alkaline condensing agent which contains no hydroxyl group or only a small quantity of admixtures containing hydroxyl groups in order to prevent saponification of the acylamino groups.  The products may be halogenated.  The acylating agents may be anhydrides or chlorides of o-halogenbenzene monocarboxylic acids, e.g. 2-chloro and 2-bromo-benzoyl chloride and 24-dichlorobenzoyl chloride.  A solvent such as nitrobenzene, naphthalene, or dichlorobenzene may be employed.  The products dye or print wool, silk, cotton, linen, regenerated cellulose and nylon olive shades.  Examples describe: (1) the acylation of the alkaline condensation product with 2-chlorbenzoyl chloride, and also the chlorination of the product with sulphuryl chloride and its bromination in glacial acetic acid; (2) the acylation of the alkaline condensation product with 2.4-dichlorobenzoyl chloride; (3) the acylation of 5-amino-5 - amino - 1 - (Bz.1 - benzanthronyl) - 1 - aminoanthraquinone with 2-chlorbenzoyl chloride, followed by condensation with sodium alcoholate in p  aniline.

Abstract: 697,707. Actuation of switches. AMERICAN STEEL FOUNDRIES. Oct. 23, 1951 [Dec. 21, 1950], No. 24775/51. Class 38 (v) [Also in Group XIX] A switch 30 is actuated by a fluid-pressure responsive device comprising a spiral spring 22 which has its inner surface sealed by resilient material flowable under pressure and sealing members 10, 18 connected at opposite ends to form a closed chamber with a passage 13 for the application of pressure fluid. The lower sealing member 10 is fixed in a frame member 6 and the upper sealing member 18 is rotatable and has an upwardly-extending portion 24 which operates the switchactuating member 28 as the spring 22 uncoils on the application of pressure to the device. The resilient material may be a rubber tube 14 with its ends fitted within annular flanges 12, 16 of the members 10, 18, the spring 22 being secured to the flanges by hose clamps 41. Alternatively, the spring 22 and the sealing members 10, 18 may be moulded into rubber to form a unitary assembly. A thrust race 20 is provided between the member 18 and a frame member 4.

Title: Improvements in or relating to windscreen cleaning devices
IPC: B60S1/48
Filed: 1963-06-21
Abstract: 962,524. Windscreen cleaners. FORD MOTOR CO. June 21, 1963 [June 25, 1962], No. 24853/63. Heading A4F. A windscreen cleaning system comprises a wiper with a driving motor and coupling means, a switch periodically operated by said coupling means, a pump with fluid chamber a n d outlet, a spray nozzle, an electrical actuating means in circuit with said switch to actuate a piston means connected operatively to said fluid chamber, and to a reservoir, to force fluid from said chamber, through said outlet to said nozzle, when operated by said actuating means, and to permit flow from said reservoir to said chamber when said actuating means is inoperative. The switch is operated by the coupling means periodically to synchronize the washer action with that of the wiper blades. As the shaft 12, connected to the wiper blades, turns due to the action of the wiper motor, the segments 14 of the rotor 11 make and break alternately with the stator 19. When the driver operated switch 5 is closed, a circuit is completed by the contacts 14, 19 to energize the solenoid coil 29 which then draws down the armature or piston 36, through the fluid chamber 30 to expel fluid through the outlet 34 to the spray nozzles. The ingress of more fluid from the reservoir 40, is prevented by the check valve 38. As the shaft 12 turns further, the circuit is broken, solenoid 29 is de-energized and armature 36 returns to the top of float chamber 38 due to the action of spring 6. Whilst this is happening fluid may flow past valve 38 into float chamber 30, ready to be expelled by the next stroke of piston 36. An alternative embodiment is described in which the reservoir is not integral with the pump, whilst the fluid chamber incorporates a relief device to prevent damage due to the fluid freezing.

Abstract: 830,184. Substation equipment. AUTOMATIC TELEPHONE & ELECTRIC CO. Ltd. July 21, 1958 [Aug. 8, 1957], No. 24977/57. Class 40 (4). In a substation arrangement for substituting (or providing in addition) a more melodious bell or chime, a rectifier arrangement MR is arranged to receive incoming ringing current and charge a condenser C4 and to operate a relay RL. When the relay operates the condenser C4 discharges over an early operating contact rl1 through the winding BC of a D.C.- operated bell or chime. Contact rl2 releases late to ensure full operation of the relay whereupon parallel condenser C3 discharges slowly through relay RL to delay its release. On release the cycle is repeated. The arrangement may be connected directly across the line, or across terminals W and G, a strap being put across the magneto bell MB. In this case condenser C5 may be dispensed with. The bell or chime may be of the gravity-restored plunger type.
