Title: Improvements in and relating to shock absorbers
IPC: F16F9/36
Filed: 1952-12-10
Abstract: 727,517. Hydraulic shock-absorbers. BOURCIER DE CARBON, C. M. L. L. Dec. 10, 1952 [Dec. 10, 1951], No. 31312/52. Class 108 (3). A pneumatic shock-absorber comprises a piston P movable in a cylinder C, the pneumatic pressure in which (when the device is 140 stationary) is greater than S atmospheres (S being the crosssectional area of the cylinder in square centimetres). The piston has a passage G which may be controlled by a valve, the opening of which is proportional to the pressure difference between opposite piston faces. This passage may be supplemented by a further open passage or passages. Instead of passages through the piston there may be an annular passage afforded between the piston and cylinder walls. An oil seal M<SP>1</SP> is disposed between spaced glands E<SP>1</SP>, E<SP>2</SP>. The upper gland may be dispensed with (Fig. 2, not shown).
Patent GB-314498-A (GB)
Abstract: 314,498. Palmeri, C. June 28, 1928, [Convention date]. Alkaloids.-In a continuous process for extracting alkaloids, in the form of their salts, from plant materials which contain them, such materials are macerated in a vessel 1 in a concentrated solution of a salt, such as sodium or calcium chloride, which is a strong electrolyte, preferably made alkaline 'by the addition of a base such as calcium, sodium, potassium, or ammonium hydroxide. In this treatment the alkaloids are transferred to the solution, organic acids, chiefly pectic acid, and colloidal substances being precipitated. The extract is then forced by means of a pump 4 to the top of a tower 2, which contains, above the level a a, an organic solvent, such as a high-boiling petroleum oil which is lighter than water and immiscible with the solution. As the solution descends through the solvent, suitable means being employed to ensure a large contact surface between the two liquids, the alkaloids are partly transferred to the latter. The cock 6 controlling the pipe 5 being normally open, the spent solution at the base of the tower, below a a, is returned to the vessel 1 by the pressure of the liquid column above it. The solvent saturated with alkaloids is conveyed by means of a pump 7 to the base of a tower 3 containing a solution of a suitable acid, such as sulphuric, formic, or oxalic acid, the alkaloid salts of which are thus formed as the solvent ascends through it, the regenerated solvent being returned to the tower 2 through the tube 8.

[Class 34 (ii).] A retort for distilling and drying bituminous and other similar materials, as shown in the Figure, comprises a vertical chamber divided into two compartments 26, 27, the upper for drying and the lower for distillation. The material under treatment passes from a hopper 28, located above and to one side of the retort and provided with an adjustable discharge opening 29 extending the full depth of the retort, on to a plurality of horizontally disposed drying grates 31 arranged in a zig-zag manner, the drying gases, for example, flue gas, superheated steam, producer gas or mixtures thereof passing up through the grates. Means are provided for feeding the material from grate to grate and for agitating the same. Preferably this is effected by constructing the grates in the manner that each grate is formed of a plurality of independent bars in two or more lengths, means 56 being provided whereby the bars are pulled back one by one, and returned simultaneously. Removable connecting-rods 57 pass through water-cooled covers 58, the lower portions of which constitute dust collectors. The drying gases enter the chamber by pipe 38 and are exhausted by fan 42. Material passing through the grate bars is removed through door 40. After drying, the material passes to the distilling chamber 27. Inspection windows 72 may be provided.

Title: New curing catalyst for aminoplast resin compositions
IPC: C08L67/00
Filed: 1957-10-11
Abstract: A curing catalyst for an alkylated aminoplast is the mono-salt of maleic acid with triethylamine.  The preferred aminoplasts are from urea or an aminotriazine, e.g. melamine or acetoguanamine and they are preferably alkylated with an alcohol having 3 to 6 carbon atoms, e.g. a butyl alcohol, 2-ethylbutanol, n-hexanol or cyclohexyl alcohol.  The aminoplast may be mixed with an alkyd, especially a long-oil alkyd.  The salt may be formed in a solution in isopropyl or n-butyl alcohol and may be used as such.  The compositions may include other solvents, e.g. ethyl acetate, ethoxy- or butoxy-ethyl acetate, acetone, butanone, methyl ethyl ketone, dioxane, dimethylformamide, dimethylacetamide, nitroparaffins, acetonitrile, aromatic hydrocarbons or chlorinated hydrocarbons.  The compositions may also include fillers, pigments, extenders or delustrants. Examples describe the following compositions:-(1) and (4) A composition containing Ti O2, an oil modified alkyd from phthalic anhydride glycerol and coconut oil acids, a butylated urea-formaldehyde condensate, xylol, butanol, and the maleic acid mono-salt of triethylamine is coated on steel panels, dried and cured.  Results are compared with those obtained using the same composition but with other acid catalysts.  Example 2 is similar using a butylated melamine-formaldehyde condensate while Example 3 uses a butylated acetoguanamine-formaldehyde condensate.  Examples (5) and (6) use an iso-propyl alcohol solution of the monomaleate of triethylamine to cure a film made from a solution of n-butylated urea-formaldehyde condensate in xylol/butanol.

Abstract: 1,198,801. Laminating process. UNITED GLASS Ltd. 19 July, 1967 [19 July, 1966], No. 32399/66. Heading B5N. A laminate is produced by pressing a metal layer into contact with a layer of thermoplastic material, the metal layer being heated by means of an induced radio frequency current to a temperature sufficient to cause either the thermoplastic material to soften and thus adhere to the metal or a coating of thermoplastic material on the metal layer to soften and thus adhere to the thermoplastic layer. The two layers may be pressed together between two pressure rollers, within one of which, e.g. that adjacent the thermoplastic layer, an induction coil, for inducing the R.F. current, may be located. Alternatively, both layers or just the metal layer may be passed through the field of an induction coil before being pressed between the rollers. The surface of the thermoplastic layer may be activated, e.g. by heat, high frequency corona discharge, or the action of a gas which causes the surface to become polar, before the layers are pressed together. The metal layer may be of tin, aluminium or tin-antimony alloys. The thermoplastic layer may be of polyethylene, polyproplylene, P.V.C., cellulose acetate, polycarbonates, phenoxyresins, polystyrene or styrene co-polymers such as A.B.S. The thermoplastic layer may have bonded to its surface remote from the metal a layer of woven or non-woven material, paper, cardboard, or foamed polyurethane or foamed P.V.C.
