Abstract: A screen cover 1 consists of several long and narrow screen elements and is held against a support element 9 for a screen frame 7 by means of stiffening elements 3 which are part of the screen cover. The stiffening elements can independently serve as a part of a fastening arrangement 3, 8, 10, 13 by being elastically deformed against the support element 9 with a recoil resultant force that is greater than an oppositely directed resultant inertial force acting on the screen fabric during sifting in a dynamic sifting machine. When using the stiffening element 3 of magnetic material, the screen element 1 is held fast or the holding of the screen element against the screen frame 7, 9 is boosted by means of permanent magnets 13, which magnetically attract the stiffening element 3. <IMAGE>

Title: Retreading tyres - edges of rubber to bond cured tread to carcass are additionally heated to prevent cooling
Inventor: GRIPENHOLT N
IPC: B29C35/08
Filed: 1982-05-12
Abstract: Tyres are retreaded by using a pre-vulcanised tread and an uncured layer of rubber between this and the carcass, the rubber being cured by applying high frequency from above the tread. This rubber is also locally heated at or near its edges by extra heating outside the tyre. Specifically the same h/f generator is used to heat both the outermost area of the rubber adhesive between carcass and tread and also the edges area of the rubber. The h/f energy is therefore more efficiently utilised, and the edge application is adjusted so that it at least equals the heat losses from those areas. The whole cure of the adhesive rubber layer is thus made more effective. As an alternative to using high loss factor rubber for h/f heating the edges, e.g. a ring of high loss factor material can be applied to each edge area and thus heat up the rubber edges externally. Method eliminates the usual problem of cooling at the edges when the assembly is cured in an autoclave contg. unheated pressurised air.

Abstract: On both sides of the building opening, this seal has apron-like sealing strips which are designed as air-filled inflated bodies and over which there is located a roof-type, panel-type covering, in front of which there is a transversely running apron which is likewise designed as an inflated body. In order to eliminate heat losses in the case of heated buildings or cold losses in the case of cold stores or the like, the covering is designed as a sandwich panel having, between thin-walled outer layers, an insulating, porous or cellular layer which is a wall thickness which is considerably greater than that of the two outer layers.

Abstract: The Application shows an automatic apparatus for moving sheets from a printing press to a sheet-stitching or binding device, in which no manual handling of the sheets is required at all. The sheets are firstly made into a pile on a stacking device and then passed to a base where a gripping mechanism moves the sheets to a station adjacent to the feed device of a binding device. An automatically operating gripping device then moves the plates from the station to the feed device of the binding device depending on the sheet requirement of the delivery station. A special base and a gripping mechanism are coupled to one another in such a way that the gripping mechanism can engage with the base and receive the base with the sheet pile, and the gripping mechanism can eject the sheet pile from the base at the point of the feed device of the binding device. <IMAGE>

Abstract: In a clutch arrangement for coupling together two members which move rectilinearly or rotate relative to one another, one member (10) is provided with guide means having mutually parallel guide surfaces along which a coupling element (13,14,16) is slidingly guided, with each of two gripping surfaces (15,16a), each abutting a respective guide surface (20,21) when the other of the members acts in one direction upon a lever-forming and power-transmitting part (13) of the coupling element, and is clamped firmly against the guide surfaces when the lever-forming part is acted upon in the opposite direction. The two gripping surfaces (15,16a) of the coupling element may be located on two mutually separated main components (14,16) of the coupling element which are movable relative to one another and which have a common centre of rotation (22) lying close to or in a plane passing through one guide surface (20) of the guide means.

Abstract: The invention relates to a comminution device, in particular for chopping complete trees, tree crowns and felling remnants. The separation of waste materials during the comminution operation is to be improved by an air flow coming into effect against the flight direction of the separated wood particles in order to sift the flow of material. According to the invention this is achieved by the configuration of the drum chopper similar to the type of construction of a radial fan. The air passes from the end faces of the chopping drum into an axially arranged air-feed duct and flows via connecting ducts through the chip pockets in an approximately radial direction to the outside. The air flow is regulated by further devices.

Abstract: One or more components are determined in a sample by bringing said sample, which can be a liquid or a gas, into contact with a medium for adsorbing or taking up the components in question. A light beam (4) is led via an optical cable through the medium (3) containing the adsorbed or taken-up compound sought for, is reflected against a reflector material (5) back through the medium (3), and the emitted light beam (6) is detected. In enzymatic reactions, inter alia, a membrane (7) can be utilized between sample solution and reagent, said membrane enabling the actual component to diffund through the membrane and react with the enzyme, avoiding thereby the measurements to be disturbed by strong coloration and/or a high content of impurities in the sample solution. The membrane thereby serves as a reflector material for the light beam.

Abstract: A multiple effect evaporator system and a process for concentrating a process liquid wherein evaporated process liquid from one effect serves as heating fluid in an adjacent effect. Low energy heating fluid in vapor form is fed to an evaporative surface condenser where it is condensed and collected as clean and foul condensate. Coolant for the evaporative surface condenser is provided in the form of process liquid from one of the effects. Prior to passage into the evaporative surface condenser, the process liquid is cooled. In the cooling circuit of the evaporative surface condenser, the process liquid absorbs the heat of condensation of the heating fluid and subsequently rejects the heat into a counter flowing air stream. The process liquid is thereafter heated and returned to another of the multiple evaporator effects.

Abstract: A method and an apparatus for selectively removing, by liquid absorption, hydrogen sulphide from a gas containing both hydrogen sulphide and carbon dioxide, are disclosed. In a first stage of the method, the gas (3) is in a container (1) contacted, in at least one step, with a carbonate-containing alkaline solution whose pH is adjusted during the absorption by the addition of a hydroxide, such as sodium hydroxide. In a second stage of the method, the gas is combusted in a combustion device (32) for converting the hydrogen sulphide remaining in the gas to sulphur dioxide, which then is absorbed in an alkali-containing solution, such as a sodium hydroxide solution, in a wet cleaner (36). By combining the absorption of hydrogen sulphide in a carbonate-containing solution in a first stage, and the combustion of the remaining hydrogen sulphide to sulphur dioxide and the absorption of the formed sulphur dioxide in an alkaline solution in a second stage, one may attain a total hydrogen-sulphide separation of high selectivity, high degree of separation and good process economy.

Abstract: The system includes a memory block (1) in which there is stored each journey, divided into sections identified by their theoretical absolute position parameters, length and radius and in which the correction curves are stored. At least one recording unit sensitive to travel in a curve and a relative position recorder, send signals to a control unit. The control unit uses these signals to establish the variation profile of the actual correction curves parameters. The control unit undertakes an adjustment based upon achieving the minimum error in the profiles of coordinates obtained using the theoretical parameters and the actual parameters, determining the absolute real position of the vehicle. The recording unit may be a sensor for measuring the turning velocity in a bend of the vehicle and the relative position recorder may supply information to measure the variation of the position of the vehicle and its absolute speed in the direction of travel.
