Patent FI-973736-A (FI)
Inventor: HAUTALA JOUKO
IPC: D21B1/32
Filed: 1997-09-19
Abstract: An apparatus for cleaning a fiber mass suspension, the apparatus comprising a receptacle and an inlet channel and an outlet channel for feeding the suspension into and for discharging it from the receptacle. In addition, the apparatus comprises air feed means for feeding air into the lower portion of the receptacle. The apparatus comprises at least one partition wall dividing the receptacle into spaces in such a way that the suspension may flow between the spaces at the lower portion and the upper portion of the partition wall, respectively. The air feeding means are positioned to feed air into one aeration space, whereby the air separates impurities from the suspension and makes the suspension flow on different sides of the partition wall upwards and downwards, respectively, so that a spiral flow is created around the partition wall from the inlet channel into the outlet channel.

Abstract: 876,160. Planographic printing surfaces. RITZERFELD, W., and RITZERFELD, G. Jan. 12, 1959 [Jan. 24, 1958; April 26, 1958], No. 1004/59. Class 100(2) A method of making a lithographic printing master sheet having a metallic printing surface comprises the steps of applying an inscription with a fat-containing or fat-accepting material to a smoothly rolled non-roughened metallic surface of a lined or unlined metal foil and treating the inscribed surface with a suspension of calcium hydroxide and a solution of a synthetic or natural organic colloid. Prior to providing the inscription the surface may be treated with a solution of phosphoric acid. The organic colloid is preferably gum-arabic. The metal foil 1 may be aluminium or aluminium alloy or zinc or zinc alloy and is preferably cemented by a layer 2 to a supporting base of paper 3 of a weight between 50 and 80 grams per square metre. The foil is between 0À01 and 0À04 mm. thickness. The organic colloid solution may be applied together with or after the suspension of calcium hydroxide. In an example, the metallic surface was treated with a solution of 20 grams of gum-arabic, 80 grams water, and 50 grams 10% calcium hydroxide suspension in water. The amount of calcium hydroxide may be varied between 2 and 15 grams relatively to the remaining components and the amount of gum-arabic between 10 and 30 grams.

Abstract: 553,013. Controlling lift gates. POLLARD & CO., Ltd., E., and HAMMOND, E. N. Jan. 29, 1942, No. 1231. [Class 78 (iii)] The car gate of an electric lift is made selfclosing, except when one of the landing gates is open, by spring or weight-operated means controlled by an electrically operated brake. Fig. 1 shows a weight 10 attached by a chain 11 to a point 13 on the car gate 7 and tending to bring the gate to closed position. Attached also to the point 13 is a chain 25 which passes round a pulley 26 and over a sprocket-wheel 19 loose on a shaft 16 which carries a brake drum 17. A weight 27 guided in a tube 28 maintains the chain 25 taut. A pawl 20 on the drum 17 engages a ratchet wheel 18 integral with the sprocket 19 so that when the drum is held by a brake shoe 21, the gate can readily be opened by hand but is prevented from automatically closing. The shoe 21 is mounted on a pivoted rocker 22 spring-pressed at 23 to apply the brake and influenced by an electromagnet 24 to release same. The magnet 24 is controlled by the gate switch 34 or, if such is fitted, with a floor switch operated by the load. Double contacts may be provided at 34 to cut off current from the magnet 24 as soon as the gate closes. When a floating-floor is fitted the gate must be closed by hand when a load is being carried.

Patent GB-816253-A (GB)
Title: Improvements relating to the production of benzaldehyde from toluene
Inventor: HARRIS ROBERT W
IPC: C07C17/14
Filed: 1957-01-15
Abstract: A process for the production of benzaldehyde comprises reacting toluene at elevated temperatures in the liquid phase with chlorine until no more than about 35 per cent of the toluene has been converted to benzal chloride, distilling the reaction mass to separate the benzal chloride and hydrolysing the benzal chloride to benzaldehyde.  The toluene should be dry and substantially pure, e.g. nitration grade toluene.  The chlorination may be effected by bubbling chlorine into toluene or refluxing toluene in the presence of gaseous chlorine.  The chlorination may take place in the presence of ultra-violet light or phosphorus trichloride. Plastic or glass reaction vessels should be used; the use of metal-containing catalysts or equipment being avoided.  The hydrolysis may be effected with aqueous sulphuric acid, steam and compounds of zinc or water. In examples: toluene is chlorinated under reflux whilst exposed to ultra-violet light, until the specific gravity rises to 1-16 at room temperature.  The chlorinated product is fractionated and the benzal chloride fraction is hydrolysed with steam to obtain benzaldehyde (1), and in a similar process the chlorination is discontinued when the specific gravity rises to 1.02 at room temperature (2).  Other fractions obtained contain benzyl chloride and mixtures of benzyl and benzal chlorides.  The benzyl chloride may be returned to the chlorination process.

Abstract: 713,975. Laying dust in mines. SCHLOCHON, E. A. C., and ROHE, J. Jan. 22, 1952, No. 1790/52. Class 85 To reduce fire risks due to dust in mine workings, the dust is made innocuous by a damped salt which absorbs the dust when it settles thereon. The salt, such as sodium chloride or a hygroscopic salt, is spread in a dry state over the floor of the mine and is subsequently damped. A supplementary salt crust may also cover the timbering, this crust either being formed of damp salt which is held on the timbering, if necessary, by an adhesive substance, such as a sulphite obtaine from the residues resulting from the manufacture of cellulose, or by spraying the timbering with an aqueous solution having a high salt concentration. The salt surfaces so formed in the mine are continuously or intermittently moistened, either by direct spraying or by absorption from moistened ventilating air. At places where there are dust concentrations, the air may be drawn through a filter impregnated with salt.
