Title: Improvements in or relating to portable washing apparatus, vacuum cleaners and immersion heaters
IPC: D06F17/00
Filed: 1927-03-22
Abstract: 293,081. Vize, D. N., and Woolley, J. E. March 22, 1927. No Patent granted (Scaling fee not paid). Motors, gearing for.-A circulating device for washing liquid is made in two parts adapted to be detachably secured together. The lower part k houses a rotary pump o, the upper end of the pump shaft p being bifurcated and a forked coupling member r pivoted therein which is engaged by the projecting end of a motor shaft e. The motor is housed in the removable upper part of the circulating device, which is detachable secured to the lower part by clamps i. After removal from the circulating device the upper part may be clamped to a vacuum cleaner having an air suction pump. Alternatively the air suction pump may be incorporated in the upper part, in which case, when this part is to be used with a vacuum cleaner, the projecting part of the motor shaft is covered with a screw cap, Fig. 7.

Title: Improvements in or relating to means for determining the altitude of an aircraft
IPC: G01S11/02
Filed: 1947-03-21
Abstract: 636,204. Current and voltage measurements. COMPAGNIE GENERALE DE TELEGRAPHIE, SANS FIL. March 21, 1947, No. 7850. Convention date, April 6. 1946. [Class 37] [Also in Group XL (c)] A radio altimeter comprises means for transmitting short waves (of the order of 3 cm.) towards the ground and receiving the energy reflected back therefrom to obtain standing waves in the wave-guide feeding the radiator, means for imparting a reciprocating movement to a probe so that it intersects the standing waves and means to measure the amplitude of the low-frequency component of the voltages induced in the probe. The amplitude of the standing waves is dependent on the coefficient of reflection of the ground, the wavelength, and the height, and thus the height may be determined from the amplitude of the low. frequency induced in the probe. The probe 4 may be associated with a detector 2 and its circuit enclosed in a case 1, the whole being reciprocated along a slot in the feed waveguide 3 by motor 7 and crank 6. The continuous current, due to the high frequency detected, is eliminated and the low frequency due to the motion of the probe is fed through condenser 11 and flexible leads 8 and 9 to amplifier 10 and rectifier 13. The coefficient of reflection of the ground is stated to be normally about 80 per cent for a wavelength of 3 cm. and thus a milliameter in the rectifier circuit may be calibrated directly in height.

Abstract: 1,247,482. Debromination of brines. IMPERIAL CHEMICAL INDUSTRIES Ltd. 28 Jan., 1970 [13 Feb., 1969], No. 7887/69. Heading C1A. Brines are debrominated by acidifying the brine, chlorinating it, and removing the liberated bromine by passing a stream of air containing chlorine through the chlorinated acidified brine. The brines may comprise one or more salts other than bromide (normally chlorides) of alkali metals, alkaline earth metals and magnesium. Chlorination may be effected by chlorine alone but preferably with part of the chlorine in the air stream. Temperatures of 15-70‹ C. are suitable. The bromine in the issuing air stream may be recovered, e.g. by scrubbing. Chlorine content of the air is preferably in the range 0À0001 to 5%.

Title: Flexible conduit
IPC: B29D23/18
Filed: 1956-03-20
Abstract: 813,700. Flexible conduits. DAYTON RUBBER CO. March 20, 9156 [March 24, 1955], No. 8594/56. Class 99(2) In a flexible, radially non-collapsible, conduit having circumferential reinforcing means with axially spaced turns and a yieldable, deformable surface layer, the reinforcing means, formed by a helix 12, is surrounded by a plastic and deformable tube 14 having corrugations formed therein, which corrugations depend between the turns of the helix so as to straddle the turns and extend to the plane of the innermost surface portion of the helix. The inner surfaces at the crests of the corrugations are bonded to the peripheries of the turns of the helix over a portion only of the embraced areas of the turns whereby on the application of tension, as by bending or stretching, the portion of the tube normally embracing but not bonded to the turns of the helix will pull away therefrom and return to embracing position on release of that tension. As shown, the reinforcing helix 12 is of synthetic plastic or of wire coated with synthetic plastic and has a flat, inner surface 11a. The inner peripheries of the corrugations may be flat. The coating is deposited on the wire by immersion in, spraying on or extrusion of the plastic. The tube 14 may be of natural rubber or synthetic rubber-like composition such as the polychloroprenes known as Neoprene the butadiene-styrene copolymers known as Buna-S or GR-S (Registered Trade Mark), the butadiene-acrylic nitrile copolymers known as Buna-N or GR-A, the polysulphides known under the Registered Trade Mark "Thiokol", butyl rubber, vinyl copolymers, cellulose acetate, cellulose acetate butyrate and polyethylene. In making the conduit, a preformed tube 14 is distended by the application of air pressure and passed over the helix which has previously been positioned on a hollow, perforated mandrel, the convolutions of the helix being spaced apart and placed under tension to bear against the surface of the mandrel. The latter together with the hose assembly is then placed in a pressurized vulcaniser or oven and a differential pressure is applied between the exterior of the tube and the interior of the mandrel so that the tube becomes corrugated and embraces the convolutions of the coil. The softened condition of the plastic material used for the tube and coating of the coil is such as to cause fusion or coalescence; alternatively, bonding between these parts is effected by a solvent or adhesive.
