Abstract: PCT No. PCT/SE85/00093 Sec. 371 Date Oct. 25, 1985 Sec. 102(e) Date Oct. 25, 1985 PCT Filed Feb. 27, 1985 PCT Pub. No. WO85/04115 PCT Pub. Date Sep. 26, 1985.A filter comprises a filtering wall (2) which has a front face and a rear face and which is normally permeated by a medium in a direction from the front face towards the rear face such that the pollutants entrained by the medium are separated at the front face of the filtering wall and the purified medium is allowed to pass through the wall and into a space behind the filtering wall, the flow of medium through said wall being reversible, if so desired, in order to remove said separated pollutants from the front face of the filtering wall so as to clean said wall. According to the invention, the front face of the filtering wall is provided with one or more elastic cover elements (9) which are movable relative to the filtering wall and adapted upon reversal of the flow of medium, by elastic deformation under the action of said flow, to be removed wholly or partly from the wall while working said separated, adhering pollutants in order to facilitate the removal thereof.

Abstract: Resonant tubes of a pulse combustor are immersed in a bed of solid particles in a reaction zone to provide indirect heat from the pulsating combustion gases to the solid particles of the bed. The bed is maintained in an agitated state by a gas or vapor flowing through the bed. Reactant materials are introduced into the agitated bed and undergo reaction at enhanced rates resulting from heat transfer coefficients at least about twice as high as those of steady flow combustors and an intense acoustic pressure level propagated from the pulsating combustor into the reaction zone. The apparatus is useful, for example, to steam reform heavy hydrocarbons and to gasify carbonaceous material, including biomass and black liquor to produce combustible gas at relatively low temperatures, with steam being utilized as the bed fluidizing medium. Black liquor gasification, utilizing sodium carbonate as bed solids, results in liquor energy and chemical content recovery without smelt production. <IMAGE>

Abstract: A method of manufacturing a low calorie spread having a relatively high amount of milk fat, in which a protein containing water phase is brought to emulsify in a fat phase comprising butter fat and butter strange oils and/or fats to directly form a water in oil emulsion having a total fat amount 36-40% or more. The preparation of the fat phase is started by cooling cream to a temperature of +3-+15 DEG C and storing the cream at said temperature for a period of between 6 and 24 hours than subjecting the cream to a pressure of such magnitude that the cream emulsion is broken up. The broken cream emulsion is separated on a sieve like plate or drum whereby a fraction of butter particles are collected and a fraction of butter milk is drained. The collected butter particles are heated to a temperature above the melting point of the butter fat and are mixed with the butter strange fats and/or oils and possibly with further fat soluble ingredients, and a water phase comprising a protein concentrate of any known type and prepared in any conventional way is brought to emulsify in said fat phase to provide the water-in-oil emulsion, and finally the emulsion is pasteurized, cooled and packed.

Abstract: A method of manufacturing a polysulphide polymer, in particular for use as a sealant in the construction industry and the like. A liquid polysulphide prepolymer is partially cured with an oxidizing curing agent such as calcium peroxide, by adding a controlled amount of water. As the cure reaches the end of its induction stage, before the viscosity rises substantially, the reaction is stopped by dehydrating with a desiccant. This gives a stable liquid prepolymer which can later be cured without an induction period by exposure to moisture and optionally a further curative.

Title: Method and apparatus for loading and unloading motor vehicles from lightweight sleeves which are carried in standard cargo containers
Inventor: GEARIN PETER
IPC: B61D47/00
Filed: 1989-12-22
Granted: 1994-11-15
Abstract: A method and apparatus are provided for loading motor vehicles into an open-centered, light-weight sleeve which carries a plurality of the vehicles and is inserted into a standard cargo-carrying con-tainer.  A sled, which is arranged to carry at least one vehicle, is movable on tracks which extend from outside of the sleeve across substantially its entire extent.  Thus, vehicles can be driven onto the sled outside of the sleeve and then transported into the sleeve on the sled.  Once in the sleeve a vehicle is raised by gantries which are located outside of the side walls of the sleeve.  The gantries have lifting cylinders which releasably attach to cradle latches which are slidable on and attachable to tension members that are suspended from the sides of the sleeve.  The cradle latches engage the ends of the cradles, which are carried in the sled below the tires of the vehicle. Thus, when the cradles are raised by the cradle latches they engage the vehicle's tires and the vehicle is raised with them.  The sleds are movable by a motor-driven endless chain having a clip which is releasably attachable to the sled.  The sled includes rams which are extendable to positions where they protrude past the side walls of the sleeve.  Thus, the sled can be used to pull a sleeve out of and push a sleeve into a container.

Granted: 1999-10-12
Abstract: The dangerous gap between the moved step (1) and the fixed pedestal plates (10) provided at bath sides of the treadable stair belt is covered by this safety equipment with the aid of an elastic synthetic material lip (6; 7; 8; 9) fastened in the region of the tread surface (1.1) and the riser (1.2) at the side edges of the step (1) of an escalator. The synthetic material lips (6; 7; 8; 9) is a part of a synthetic material insert piece (2; 3; 4; 5), which can be screwed on in corresponding recesses on both sides of the body of the step (1) in the region of the horizontal tread surface (1.1) and in the region of the arcuate riser (1.2). In the case of possible inaccuracies of the pedestal plate (10), it adapts to this and displays a very low co-efficient of friction. The synthetic material lip (6; 7; 8; 9) is so made fast at the step (1) that the clearance for the passage of the step (1) through a comb arranged at the upper and at the lower end of the travel path of the escalator need be enlarged only minimally and it is screwable onto or off from the step (1) at any time together with the insert piece (2; 3; 4; 5) without the step (1) having to be dissassembled from the stair belt.
