Title: Process and device for the manufacture of gloves and new industrial product obtainedthereby
IPC: B29C41/14
Filed: 1937-07-07
Abstract: 474,594. Moulding gloves by dipping. INTERNATIONAL LATEX PROCESSES, Ltd. July 7, 1937, No. 18850. Convention date, July 7, 1936. [Class 87 (ii)] Relates to surgeons' rubber gloves of the Chaput type that it has been proposed to make on special flat formers provided at one end with four flattened fingers arranged in the manner of the slats of a Venetian blind. According to the invention, a glove 1 of the Chaput type is made by dipping a glove former of the usual type in an aqueous dispersion of rubber, drying partially the glove, flattening it between plane surfaces 2, 3, further altering the configuration of the glove by moving the plane surfaces relatively to each other, in the direction of the arrow, Fig. 2, and then vulcanizing the glove while in the altered configuration. The fingers of the former may be conical and have a finger length less than that adopted for the same size of glove former of the usual type. The gloves may have a shagreened or wrinkled surface produced by a former having a roughened surface, the finished glove being turned inside out. In some cases, the shagreening is produced by spraying or by treating the surface of the glove with solvents and coagulants.

Title: Improvements in and relating to liquid level gauges

Abstract: 904,848. Magnetic switches. BAYHAM Ltd. May 1, 1961 [May 30, 1960], No. 19090/60. Class 38 (5). [Also in Group XVIII] A liquid level gauge comprises a pointer moved directly or indirectly by a float, a permanent magnet moved proportionately to the movement of the float and a snap action switch connected in an alarm circuit actuated by another magnet mounted for free angular movement through a limited angle by mutual repulsion between said magnets. In the form shown in Fig. 1, a magnet b secured to the spindle a of a float holds a magnet e in register through a non-magnetic wall d. The magnet e and a similar magnet g which controls a magnetic pointer j are secured to a spindle f. A magnet k secured to a plate carrying a mercury switch m is mounted on the spindle f for free rotation between two stops. In operation, the magnet k is normally held against one of the stops by magnetic repulsion, and when the level falls to the preset minimum the magnet e moves over the dead point of repulsion and the magnet k snaps over to the other stop operating the mercury switch. In a modification, Figs. 6, 9 and 10, the float spindle is geared to the spindle a so that the magnet b moves through 300 degrees between " Full " and " Empty." To prevent actuation of the switch m by magnetic attraction, the spindle r of the magnet k to which is secured a bracket s carrying the switch moves between three stops t, u, v, Figs. 9 and 10. When the magnet k is repulsed the assembly is free to rotate between the stops t, v so that the switch can operate. When it is attracted the assembly moves forward axially so that the bracket end is locked between the stops v, u and the switch cannot operate. Specification 578,786 is referred to.

Title: Improvements in the manufacture of hard alloys
IPC: C22C1/05
Filed: 1923-07-30
Abstract: Hard alloys or materials suitable for tools, particularly dies, containing 3-4.5 per cent of carbon and 95.5-97 per cent of tungsten, and having a homogeneous micro-crystalline structure are obtained by melting in an electric arc followed by rapid cooling, for example by stopping the arc or by pouring the product into a mould.  Similar materials may be made in which part or all of the tungsten is replaced by molybdenum or chromium, and part or all of the carbon by boron, or silicon.  The materials may be made by heating a substance rich in carbon in an arc in a carbon-free atmosphere or under reduced pressure, or by melting a low-carbon or carbon-free material in a carbonaceous gas such as coal gas, methane, or carbon monoxide; in the case of materials containing silicon or boron, the operation is carried out in a neutral gas or under reduced pressure.  In some cases the starting material may be de-gassed by strongly heating under reduced pressure in argon or hydrogen.  Specifications 157,054, [Class 82 (i), Metals, Extracting &c.], 157,747, and 157,774, [Class 82 (i), Metals, Extracting &c.], are referred to.

Title: Improved casting process
Inventor: PARRISS WALTER HENRY
IPC: B29C39/02
Filed: 1957-07-21
Abstract: To obtain from a master pattern a casting in material, e.g epoxy resin, subject to an undesirable degree of shrinkage, a secondary pattern of smaller overall size than the master pattern is produced, a basic casting in the material is produced from the secondary pattern and introduced into a primary mould the cavity of which reproduces accurately the shape of the master pattern, and a layer of the material is cast around the basic casting so that it adheres thereto, whereby the shrinkage is limited to this layer.  The secondary pattern may be produced directly from the master pattern or indirectly from a casting obtained from the master pattern in either case by machining away a skin of material which may have a thickness as low as 3/32 inch.  The basic casting is formed from the secondary pattern by an intermediate step involving a mould obtained, as may be the primary mould, by depositing electrolytically a layer of metal on to the respective pattern, investing the coated pattern in a moulding material, and then removing the pattern to leave the metal coating as a lining to the mould.  Specification 749,600 is referred to.

Title: Improved method of and apparatus for separating gases from a mixture thereof
IPC: B01D53/22
Filed: 1922-07-19
Abstract: 196,560. Naamlooze Vennootschap Philips' Gloeilampenfabrieken. April 19, 1922, [Convention date]. Gases, sepaating mixtures of; diffusion apparatus for gases.-A gaseous mixture is separated into its components by causing it to diffuse into or against an auxiliary stream of gas or vapour, and by withdrawing portions of the auxiliary stream in which, on account of the different diffusibilities of the components of the mixture, the concentration of one or other of the components is relatively high. The auxiliary stream flows at a regulable rate and is readily separable frorn the admixed component. The invention is illustrated by reference to the separation of helium and neon from a mixture of the two. The temperature of the jacketed vessels W, D, C, which contain water, is so arranged that the temperature in W is higher than that in D or C, so that a stream of water vapour flows from W through the narrow space g at a rate depending on this difference in temperature. The gas mixture enters through the tube h at a pressure not greater than that in the vessel W, and the velocity of the water vapour stream is so adjusted that only the more diffusible component, helium, can diffuse against it into the vessel C, the other component, neon, being led away from the vessel D by a suitable outlet tube (not shown) and freed from water vapour by condensation. The helium is withdrawn into the vessel V where water vapour is removed in the same way. Each of the fractions so separated may be subjected again to the process, for example by means of a series of apparatus. The diffusion may be arranged to take place in other ways than directly against the vapour stream, and in place of water vapour any other suitable gas or vapour may be employed.

[Class 39 (i)] Mercury is introduced into a discharge tube by connecting the tube to an arm of an ovacuation system, the mercury being moved in a container along the arm during the evacuation process to a position from which it can be passed into the discharge tube in liquid or vapour form. In the form shown, each stroke of the valve piston 39 enables a definite quantity of mercury from the container 35c to flow down the passage 46 to the cup 16c on rod 13c raised into the tube 11 to which the discharge tube is connected by means of the coil 22c co-operating with the magnetic end portion 14c of the rod 13c, the coil 22c being raised and lowered by bell-crank lever 47 moving in synchronism with the valve piston 39. The cup 16c raises the mercury until it is just below the discharge tube into which it can be passed by vaporization. Simpler apparatus is described for use when a single cupful of. mercury is sufficient, and this can be introduced in vapour form or in liquid form either by inverting the apparatus when the cup is in the raised position or by injecting the mercury upwards by suddenly stopping the rapid upward movement of the reciprocating rod carrying the cup.
