Title: Improved construction of apparatus for indicating when a liquid is boiling or has been boiling a required length of time
IPC: A47J27/00
Filed: 1923-03-17
Abstract: 209,991. Heath, A. E. March 17, 1923. Signals.-An open-bottomed base 1 which will stand in a saucepan &c. carries a tube 4 with a whistle &c. at the top and, in the modified form illustrated, is provided, in addition, with means for delaying the sounding of the whistle until the water has been boiling for a predetermined time. This latter device comprises a condenser which, as shown, is formed by a partition 5 through which passes a steam coil 8, but may be merely a box-like steam chamber. The initial steam is thus condensed in heating the water in the condenser, thereby delaying the action of the whistle for a time depending on the amount of water inserted in the condenser. The device, is suitable for use when cooking eggs.

Abstract: 1400387 Measuring leaks electrically BRITISH OXYGEN CO Ltd [trading as EDWARDS HIGH VACUUM INTERNATIONAL] 23 June 1972 [24 March 1971] 7744/71 Heading G1N In an arrangement by which leaks in the welds of a tank may be detected by filling the tank with a pressured search gas, e.g. helium or hydrogen, and positioning a probe near the weld so that leaking gas may be caused to flow along a duct 4 and cool a heated element, a detecting device comprises two heated resistances 12 disposed in cavities 8, 10 in association with the duct 4. An extractor 24 draws gas through the probe tube 2 and also through a reference tube 20 not receiving the search gas. The two resistors are differentially cooled, the difference being indicative of leakage, and measurement is made using a bridge circuit. To promote convection each cavity communicates with the duct through at least two passages or contains an inner chamber enclosing the element and having at least two openings, Figs.2 and 3 (not shown). The search gas may alternatively be chloroform, carbon disulphide, benzene and methyl chloride.

Title: Process for the preparation of synthetic, thermoplastic, expandable substances and for obtaining from these substances porous shaped bodies
IPC: C08J9/18
Filed: 1964-02-25
Abstract: Expandable particles of thermoplastic polymers include as an expanding agent a chlorofluoro derivative of a hydrocarbon, or a mixture of such derivatives, which is a solvent for the synthetic plastic.  Suitable expanding agents, which preferably boil at less than 15 DEG  C. at atmospheric pressure, are chlorofluoro-substituted derivatives of aliphatic hydrocarbons with up to 4 carbon atoms and may be used in quantities from 2 to 40% by weight with respect to the weight of synthetic plastic.  The synthetic thermoplastic substance used can be polystyrene or a styrene copolymer, containing at least 50% of styrene units by weight, such as with a -methyl styrene, an acrylate, a methacrylate or butadiene.  The expanding agent can be introduced into an aqueous suspension of the thermoplastic synthetic polymer particles to form the expandable particles.  The aqueous suspension can be a suspension obtained by aqueous suspension polymerization or by grinding a mass of synthetic plastic into small particles and suspending these in water.  The expanding agent may be introduced at a temperature from 5 DEG  to 40 DEG  C. higher than the softening temperature of the synthetic plastic, into the stirred suspension over a period of 30 minutes to 3 hours.  The particles can be made into shaped porous bodies by first expanding the particles and then moulding the expanded particles with sintering.

Title: Improvements in wringers
IPC: D06F45/18
Filed: 1938-03-16
Abstract: 497,820. Wringers ; machinery guards. LOVELL MANUFACTURING CO. March 16, 1938, No. 8120. Convention date, March 17, 1937. [Class 138 (ii)] [Also in Group XXIV] The top bar 11 of a wringer is pivoted at 12 to the gear casing 13 at a point remote from the side stiles whereby on actuation of the pressure release mechanism complete separation of the rollers at both ends occurs. The top bar also forms a cover for the gear casing. The pressure is released by depressing either member 25 of two pairs of arms, one pair being provided on each face of the wringer, whereby a rock-shaft 23 is rotated to move a catch 20 counterclockwise against a spring 22 and so release a nose 19 on the lower end of a lever 14. The lever 14 is pivoted at 15 to the top bar and at 17 to a link 16 which is pivoted at 18 to the side stile 2, the pivots not being quite in a straight line when the lever 14 is held by the catch 20 in pressureapplying position. The handle 46, Fig. 8, of the clutch-actuating lever 42 is slidably mounted thereon and carries a cross-head 52 having hooks 51 of which one engages a hook 40 at the end of the slot 49 in the top bar 11 in which the lever rocks. On actuation of the pressure release arm, upward movement of the top bar frees the hooks 50, 51 and allows one of a pair of springs 44 to shift the lever 42 to neutral, shifting the clutch 39 from its forward or reverse drive position. The lever 42 can be actuated to stop the drive independently of the operation of the pressure release mechanism. Transverse rods 56, Fig. 2, extend under the upper roller shaft 8 and are carried by members 55 pivoted in the top bar whereby the roller is raised as the top bar rises.

Title: Aluminizing of ferrous metal base
Inventor: BERNICK LESLIE MYRON
IPC: C23C2/12
Filed: 1962-03-05
Abstract: In a continuous process of aluminising a ferrous base, the base is first coated with a liquid containing molybdenum trioxide, tungsten trioxide or compounds decomposable to these oxides, the coating is reduced at a temperature of at least 1850 DEG  F. to yield at least 0.3 gms. per square foot of surface of tungsten or molybdenum which is completely diffused into the base to form a diffused layer containing not more than 18% of tungsten or molybdenum, and the aluminium is then applied preferably by hot dipping.  The liquid coating may be applied as a dispersion in water containing starch or as a dispersion in oil or glycerine and the decomposable compounds may be molybdic acid, tungstic acid, ammonium molybdate or tungstate or sodium tungstate.  Reduction and diffusion is effected in hydrogen at 1850 DEG  F. to 2100 DEG  F. the difiused layer containing 0.3 to 1 gm. per square foot of diffused metal.  The aluminium coating is formed by hot dipping in molten p  aluminium at 1200 DEG  F. to 1300 DEG  F.  The ferrous strip, sheet, strand or wire may be electrolytically cleaned prior to coating and also anodically or chemically cleaned after the first coating to remove any free tungsten or molybdenum which has not diffused into the ferrous base.

[Also in Division G3] In an arrangement for maintaining the focal point of an optical lens 2, Fig, 1, on the surface of a moving optical recording carrier 3 moving transversely of the light beam and capable of varying in distance from the lens 2, the intensity of light reflected from the surface and directed through a beam-splitter 4 and a fixed aperture 6 on to a photo-cell 7 produces a signal to control a device influencing the focal distance. The signal may be compared with that from a second detector 9 which receives the entire beam reflected by a second beam-splitter 8 and serves as a source intensity reference. The source may be a laser for burning the record into a metallic coating and the fixed aperture 6 may be rectangular with its major dimension parallel to the axis of lens 2 and equal to the expected maximum diameter of unfocused recording spot. Correction may be achieved by moving the tape carrier base or by making lens 10 of electrically variable focal length.
