Title: Improvements relating to indicating the presence or level of liquid and solid materials
IPC: G01F23/296
Filed: 1936-05-21
Abstract: 475,274. Indicating excess or deficiency of feed material. McLELLAN, W. May 21, 1936, No. 14403. [Class 59] [Also in Groups XVIII and XXX] The presence or level of liquid or solid materials, e.g., in a hopper, is indicated by means of a member 1 vibrated by means of an electromagnet 3 acting on an armature 6 carried by a spring blade 13. The member 1 depends into the hopper 12 to the level to which it is to be filled, so that its movement is damped or stopped when the material reaches it. A lamp 8 in the circuit flickers regularly when the member 1 is vibrated, and the presence of material up to the predetermined level is indicated by a reduction in frequency or cessation of flicker. The apparatus may be enclosed in a housing 31 through which the member 1 passes between spring blades 11 to avoid an open aperture. In an alternative, the vibration of the member 1 may be produced by intermittent electric heating of a bimetallic strip, the curving of which makes and breaks the circuit. The indicating circuit may also be used for controlling the supply of material.

Abstract: 1,085,727. Moulding P.T.F.E.; laminates. RICHARD KLINGER Ltd. Feb. 23, 1966 [April 6, 1965], No. 14536/65. Headings B5A and B5N. An article of sintered P.T.F.E. is made by forming a layer of granular P.T.F.E. and a layer of refractory particles bound with an inorganic binder which carbonizes below 385‹ C. The two layers are pressed together whilst cold to form a physically adherent bond therebetween and the whole is then sintered at an elevated temperature below 385‹ C. to form the required article. The refractory particles may be non-metallic oxidic material or siliceous material, e.g. silica, sand or asbestos, or a refractory metal or metal alloy, e.g. iron, steel, copper, tin, zinc, bronze or brass, and the sintered article may be bonded on to a substrate of, e.g. glass or metal using a suitable adhesive, e.g. " Araldite " (Trade Mark). In the given example a " Duralumin " (Trade Mark) plate was coated with a film of " Castrol " (Trade Mark) and sand or iron filings sprayed thereon, the excess then being removed. The plate was then placed sand downwards on to a mould filled with P.T.F.E. particles and pressure applied to the plate. The composite article thus formed was removed from the mould and the plate and was heated for 36 hours at 380‹ C. The sintered article could be bonded to a plate of glass.

Title: Improvements in or relating to the manufacture and use of expanded rubber material
IPC: C08L21/00
Filed: 1930-05-14
Abstract: In the manufacture of expanded rubber by heating dough under high gas pressure, the expansion and vulcanization is effected in stages.  In an example, for producing a rigid rubber froth, a mix consisting of 60 per cent rubber, 25 per cent sulphur, 6 per cent hydrocarbon, 3 per cent magnesia, 1 per cent ceresine wax, and 5 per cent colouring matter, is placed in a container in an autoclave, and heated to a steam pressure of 8 lbs., which is reached in 30 min.  Inert gas at a pressure of about 180 atmospheres is admitted to the autoclave, and the pressure and temperature are maintained for 400 min.  The apparatus is allowed to cool for 60 min., the pressure is released, the container is removed and opened, whereupon the rubber expands to about six times its original volume.  This rubber is placed in a second mould and heated up to 85 lbs. steam pressure in 15 min., and maintained thereat for 45 min.  The rubber expands to about 13 1/2 times its original volume, and vulcanization is complete.  The product of the first stage may be formed into strips from which articles may be built and welded together in the second stage, when the surfaces of the strips unite and form solid diaphragms which stiffen the article.  Soft rubber articles can be made similarly. Long strips may be made by rolling up a strip of dough on a calico &c. backing treated to prevent sticking, binding the roll with canvas or thin metal, carrying out the first stage, unwinding to allow the rubber to expand, rolling up again and carrying out the second stage. An outer covering of linen, canvas, metal, or the like, may be attached at the second stage, and articles having a hard core and soft exterior may be made by uniting suitable first stage products in the second stage.  The material is suitable for the manufacture of buoyant blocks for lifeboats &c., mats, heat and sound insulators.

Title: Improvements in or relating to methods of shaping leather
IPC: C14B1/00
Filed: 1937-05-29
Abstract: A method of imparting a desired shape to leather consists in operating on the leather while it is in a limp condition as a result of exposure to the vapour of a suitable organic liquid more volatile than water.  The liquid which preferably should have a boiling point less than 80 DEG  C. in order not to injure the leather and is applied with a pressure up to 10 lb. gauge, may consist of the following substances used alone, viz.: propylene oxide, acetone, methyl acetate, methyl alcohol, ethyl acetate, or ethyl alcohol. Certain mixtures with constant boiling points are also suitable, examples of which are (a) ethyl alcohol mixed with one of the following substances, namely <PICT:0496389/IV/1> n-propyl chloride, chloroform, carbon tetrachloride, (b) methyl alcohol mixed with one of the following substances, namely n-hexane, n-heptane, ethyl formate, ethyl acetate, ethylene chloride, chloroform, methyl acetate, carbon tetrachloride, acetone, benzene, or (c) acetone mixed with methyl acetate or isobutyl chloride.  Suitable vapours may also be produced from certain mixtures containing water, e.g. (a) water and ethyl alcohol mixed with one of the following substances, namely ethyl acetate, trans - dichloracetylene, cis - dichloracetylene, isobutyl chloride, carbon tetrachloride, benzene, trichlorethylene, ethylene chloride, or (b) water and ethyl acetate, or (c) water and acetone.  The last mentioned is an example of a mixture without a constant boiling point.  In use, the liquids are preferably fed into a vaporizing chamber continuously in the desired proportions in order that the resultant vapour may be maintained of constant composition. The leather preferably should contain from 3 per cent to 18 per cent of moisture.  An apparatus for applying the treatment comprises a chamber 4 in which the work is placed and to which vapour is supplied from an evaporator 2 preferably electrically-heated by an element 6 and supplied with liquid from a reservoir 16 by means of a pump 20. Gauges 8, 10 indicate the vapour-pressure.  After the operation, the vapour may be allowed to pass through a condenser 12 and air separator 14 back to the reservoir 16.  The work-piece or shoe is maintained in the shaped condition until the vapour has been dissipated therefrom.
