Title: Improvements in gas filters of the oil bath type
IPC: B01D46/00
Filed: 1956-06-29
Abstract: 797,572. Gas filters. TRIGGS, W. W. (Air- Maze Corporation). June 29, 1956, No. 20177/56. Class 8(2). Trapping of oil blown from the sump 14 through an annular gas inlet duct of a filter of the oil bath type during a reverse flow of gas through an axial outlet duct 13 and surrounding annular filter elements 25, e.g., during the unloading of a compressor is effected by a centrally apertured baffle 50 and prefiltering elements 33, 34 located between said annular inlet duct and an inlet 10 of the apparatus as a whole. During normal filtration dust-laden gas from the inlet 10 passes downwardly through the axiallyspaced prefilters 33, 34 of crimped wire mesh and the central aperture of the baffle 30. The air is then diverted by the imperforate top 16 of the filter elements 25 into the annular inlet formed by a casing wall 12 and an imperforate skirt 16a which dips below the normal oil level 24 and from thence through the elements 25 into the outlet 13. A reverse flow of gas blows oil against a downwardly directed portion of the baffle and oil spray carried through the central aperture is caught by the prefilters 33, 34. Specification 657,724 is referred to.

Title: Improvements in or relating to the production of gold thioitamalic acid and salts thereof
IPC: A61K31/28
Filed: 1948-07-28
Abstract: Gold thioitamalic acid is prepared by reacting thioitamalic acid with a gold chloride or bromide or with an alkali metal gold chloride or bromide.  Also an aqueous solution of the monosodium salt of gold thioitamalic acid is prepared by reacting one mol. of sodium hydroxide with an aqueous solution of an equal molecular quantity of gold thioitamalic acid or by reacting equal molecular proportions of gold thioitamalic acid and the disodium salt of gold thioitamalic acid in an aqueous medium, or further by reacting one mol. of the disodium salt of gold thioitamalic acid with the equivalent weight of an acid stronger than gold thioitamalic acid in aqueous solution. The gold compounds have therapeutic value especially the monosodium salts when suspended in an assimilable oil (see Group III).  In examples: (1) gold thioitamalic acid is obtained by reacting an excess of thioitamalic acid with auric chloride in water.  It is stated that auric bromide or aurous chloride or bromide may also be used; (2) as in (1) except that potassium auric bromide is used; (3) the monosodium salt is obtained by mixing one mol. of the gold acid with one mol. of sodium hydroxide in water; (4) the disodium salt is obtained by adding two mols. of sodium hydroxide to an aqueous solution of one mol. of the gold acid and the monosodium salt may be prepared from the disodium salt by reacting it with the gold acid as above or by adding thereto an acid such as hydrochloric acid.  The Specification as open to inspection under Sect. 91 states that other alkali metal salts as well as alkaline earth metal salts, amine and alkanolamine salts of the acids may be prepared, e.g. those of ammonia, triethanolamine, monoethanolamine and methylglycamine, and both the mono- and di-amine salts are mentioned.  The calcium salt of the acid is also prepared by adding an excess of calcium chloride to an aqueous solution of the monosodium salt of the acid.  This subject-matter does not appear in the Specification as accepted.ALSO:An aqueous solution of the monosodium salt of gold thioitamalic acid (see Group IV(b)) in concentrations up to 20 per cent or a suspension of the salt in an assimiliable oil especially a vegetable oil such as sesame, peanut, olive, rape seed and cotton seed oils are suitable for therapeutic treatment by injection. The aqueous solution or oil suspension of the salt may be sterilized by the conventional methods, e.g. by autoclaving with steam.  The Specification as open to inspection under Sect. 91, states that an oil suspension of the calcium salt of the gold thioitamalic acid (see Group IV(b)) is also suitable for injection.  This subject-matter does not appear in the Specification as accepted.

Patent GB-443758-A (GB)
Title: A process for delustering lustrous fibrous materials
IPC: D06M15/17
Filed: 1935-07-16
Abstract: Lustrous fibrous materials such as artificial silk are delustred by treatment first with a peptized water-insoluble compound of a substance giving rise to surface active cations, which compound has been peptized with an excess of the substance with surface active cations, and then with a solution of an acidic substance, so that a water-insoluble compound is produced within the materials.  The use of substances which give intensely coloured products with iron salts is excluded.  Quaternary ammonium compounds containing high molecular hydrocarbon residues with at least six carbon atoms, analogous quaternary phosphonium, and ternary sulphonium compounds, oleyl-diethyl ethylene diamine, iso-ureas and iso-thioureas substituted by high molecular residues at the oxygen or sulphur atom, addition products of high molecular hydrocarbon halogenides with hexamethylene-tetramine, alkyl and aryl guanidines having high molecular hydrocarbon residues are specified substances which give rise to surface active cations. Acids which form water-insoluble compounds with these substances are resin acids, persulphuric acid, perboric acid, pyro or meta phosphoric acid.  The acid may be used as such or in the form of a soluble salt.  In an example fibrous materials are treated with a warm solution comprising a compound of colophony or like resin with lauryl pyridinium bisulphate peptized with excess of the latter.  The matt effect is deepened by treating the goods in a second bath containing resin soap.  Aluminium or barium salts may be added to the rinsing water to fix excess of resin soap. Artificial silk so treated acquires a silk-like matt lustre and full feel.  In other examples, asymmetric diethylamino-ethyl-oleyl-amine hydrochloride, or lauryl pyridinium bromide is used; sodium pyrophosphate is used instead of resin or resin soap; barium chloride is added to the first bath.  The goods may subsequently be dyed.

Title: Improvements in or relating to detector mechanism for sheet feed mechanisms
IPC: B41F33/00
Filed: 1922-07-26
Abstract: 204,452. Anglo-American Inventions Syndicate, Ltd., (Harris Automatic Press Co.). July 26, 1922. Tripping-arrangements.-A sheet-detector mechanism for tripping printing- machines, comprises a plurality of detectors, preferably arranged normally in advance of the front stops for the sheet-feed, each detector being capable of tripping the printing-cylinders if the sheet does not act on it to move it positively from its normal position. The machine is thus tripped if a sheet is not fed, or if not registered accurately, or if it is torn or folded back at the edges. The detector-mechanism is adjustable for dealing with different kinds of stock. As applied to a machine in' which the sheets are registered against rising and falling front stops 20, Fig. 2, individually adjustable on an oscillating shaft 21, and are fed by rollers 13, 15 to the grippers of an impression cylinder 9, a plurality of detectors 25 are carried by levers 27 mounted on brackets 29 on the arms of the stops 20. The detectors are adjustably connected to the levers 27, and normally are maintained in a vertical position in front of the stops by means of springs 32, the detectors passing through slots in the feed plate 17. Each detector controls the position of a lever 35 formed with a thrust-block 41 which is moved between two jaws 50, 51, of levers 45, 49, if the detector corresponding to any of the levers 35 is not acted upon by the sheet. The block 41 causes the rocking lever 45 to act upon the lever 49, and a latch 53 is released, thereby permitting a shaft 56 to be rotated by a spring and thus by a crank-mechanism to rotate eccentric bushes in which the cylinder 9 is mounted, and thus trip the cylinder. In a modified form, shown in Fig. 7, the latch 53 is operated by levermechanism from a shaft 69, which is rotated by an oscillating bracket 68, when a pawl 73 thereon engages a shoulder 74 of an arm 75 fixed to the shaft 69. The pawls are integral with detectors 66 arranged in front of the stops 20. The bracket 68 is freely mounted on shaft 69, and is oscillated bv a cam 80 on the shaft of the upper feed roll. A pawl 73 engages the shoulder 74 when the sheet is not fed correctly to the corresponding stop 20, but normally this engagement is prevented by the positive movement of the detectors 66 by the sheet.

Title: Improvements in or relating to apparatus for loading wheeled vehicles with fragmentary material
IPC: B65G67/00
Filed: 1943-12-10
Abstract: 575,288. Endless-belt conveyers; loading vehicles. MITCHELL, J. F. R., and AYTON, S. Dec. 10, 1943, No. 20728. [Classes 78 (i) and 78 (iv)] In means for loading wheeled vehicles with coal, sand, gravel or other fragmentary material, the rate of movement of a succession of vehicles away from and after filling at a loading station is determined by the rate of supply of material from a conveyer to filling means arranged to deliver the material into the vehicles. The vehicles 10, Fig. 1, are propelled by lugs 34 on an endless chain 28 below the outlet 24 of a curved shoot 22 which is fed by an endless belt conveyer 20, Fig. 2. A rotary member 64 having apertures 68 in its periphery is placed between the shoot and the vehicles. The chain 28 is driven by a motor 36 through a change speed gear and chain-and-sprocket reduction gearing, but the change speed gear may be omitted if the motor is a variable speed one. The operator stands on the platform 63 and adjusts the speed of the chain 28 to the 'rate at which material is being delivered by the conveyer 20. The member 64 is rotated intermittently by the engagement of the tubs with members 70 pivoted to it. In a modification (not shown) the shoot and rotary member are dispensed with and the conveyer discharges directly into the vehicles. Spillage is prevented by transverse members connecting a pair of parallel endless chains which are interposed between the end of the conveyer and the vehicles. According to the Provisional Specification a short length of the conveyer 20 may be supported on knife edges and connected by levers to an arm which in turn is connected to the pattern lever of the variable-speed gear box.
