Title: Column bubble tray having edge seal of plastics or rubber - located in groove of upstanding removable flange at tray perimeter
Inventor: RIEMER KARL ING
IPC: B01D3/32
Filed: 1980-12-18
Abstract: A column tray, esp. sieve tray, bubble tray and/or valve tray has an upstanding rim or flange adjacent to the inner wall of the column shell. This flange is sealed to the column shell by a sealing cord of circular, oval or annular cross-section in its undeformed state. The cord is made from an elastically and/or plastically deformable material, esp. rubber, silicone, rubber or plastics, more esp. polyalkylene, polyethylene or polytetrafluoroethylene the cord fits into a beading or groove in the upstanding flange of the tray. This flange is a separate component from the horizontal portion of the tray and is pref. so designed that it can be used to exert a radial outward pressure and thus compress the sealing ring. Used for a heat exchange or mass exchange column. The arrangement enables the seal to be easily replaced and eliminates the requirement for packing or tamping operations at each column tray when a new seal is installed. Particles or pieces of fibre are not washed out of the seal to pollute the column contents. The material does not tend to become soaked in the material processed in the column, requiring thorough flushing out when a change in prod. is required.

Title: Process for spray coating industrial articles, in particular electrical equipment, and coating aid for carrying out this process
Inventor: STEUP WALTER
IPC: B05B14/00
Filed: 1981-02-12
Abstract: The invention relates to a process for spray coating industrial articles, such as tape, disc, video and audio reproduction and recording equipment, and a coating aid for carrying out this process. The process consists, when coating surfaces as far as edges, the second surface terminating at the edge not to be coated or to be coated in a different colour, in the paint mist being kept away from the uncoated or differently coated surface by suction. A coating aid which generates suction in the vicinity of the edge acting as coating boundary, which suction extracts the paint mist, serves for keeping away the stray paint mist.

Title: Injection-moulding process for producing curtain hooks
Inventor: JUNG ARTUR
IPC: B29C45/00
Filed: 1981-08-28
Abstract: The invention relates to a process for producing curtain hooks, with the aid of which the assembly costs can be saved. The roller and support body are produced during one cycle in the injection-moulding process. The screening-off of the two parts during the injection-moulding operation is carried out by means of four sleeve fragments, the circumference of which in each case represents a 90 DEG section and which are joined to the main mould plates (A). By sliding the sleeve fragments together in pairs, a 360 DEG screening-off results. Recesses at the ends of the sleeve fragments make possible mould-filling of the axle and wheels. The separation of the support body is carried out by means of two slides (C) which have to be withdrawn before the mould plates (A) are opened. <IMAGE>

Title: Drive device for the drawing unit or pair of calender rollers of a card
Inventor: BARTH GERHARD
IPC: D01G15/36
Filed: 1981-10-16
Abstract: The invention relates to a drive device for the drawing unit or pair of calender rollers of a card, having a roller draw-off or comb following the doffer and having a pair of drawing-unit rollers or pair of calender rollers which follows the roller draw-off or comb and which is connected in driving terms to the doffer via a gear. The purpose of the invention to prevent running faults, occurring at high capacities and at the high doffer speeds necessary for these, as a result of the catching and tearing of the fleece between the doffer and drawing unit is served by the object of adapting the tensioned drawing of the fleece between the roller draw-off and the entry rollers of the drawing unit or calender rollers to the creeping or operating speed (slow speed or high speed) of the doffer of the card. According to the invention, the drive is arranged between the roller draw-off or comb and the drawing unit or calender rollers as a shiftable two-stage gear with a slow speed for the creeping mode and a high speed for the normal operation of the card. <IMAGE>
Patent DE-3141549-A1 (DE)
Title: Device for drying especially fine-grained solid particles in a stream of carrier gas and drying gas
Inventor: HULTSCH GUENTHER
IPC: F26B7/00
Filed: 1981-10-20
Abstract: In such a device, the solid particles are subjected to a rotary and centrifugal motion and held in a fluidised bed, and dried, by a stream of carrier gas and drying gas entering radially inwards through a perforated drum shell. Due to the centrifugal force of the solid particles, the velocity of the gas stream can be kept greater than in a normal fluidised bed, whereby the drying effect is improved and even fine-grained materials can be dried in the fluidised bed. This requires a defined length of the transport path of the solid particles. There is then a risk that the gas stream causes turbulence which interferes with the fluidised bed. This disadvantage is overcome by discharging a part of the stream of carrier gas and drying gas already before the end of the perforated drum, and, in the case of a short perforated drum, the drying path of the solid particles is perpendicular to the axis and, in the case of a longer perforated drum, the gas velocity can be held within tolerable limits.

Title: Process for obtaining purines by fermentation
Inventor: DERKOS-SOJAK VLASTA
IPC: C12P17/18
Filed: 1982-04-02
Abstract: The present invention relates to the obtaining of purines by fermentation using mutants of the microorganisms Streptomyces coelicolor A3 (2), deposited on 1.4.1982 at the Deutsche Sammlung von Mikroorganismen (DSM), Gesellschaft für Biotechnologische Forschung m.b.H., Griesebachstrasse 8, 3400 Göttingen, under Nos. DSM 2336 and DSM 2348, which have not hitherto been known as generators of compounds of this type. The abovementioned Streptomyces coelicolor A3 (2) mutants underwent submerged cultivation and excreted into the substrate xanthine, hypoxanthine, adenine and uric acid. Xanthine, hypoxanthine and adenine are purine bases which arise in the biosynthetic pathway of purine nucleotides, which in turn are derivatives for nucleic acids, while the purine uric acid occurs on further metabolism of xanthine by the enzyme xanthine oxidase.

Title: Variable ferromagnetic substrate for maps
Inventor: DOBBERTHIEN UWE DIPL ING
IPC: G09B29/10
Filed: 1982-06-22
Abstract: The invention is a ferromagnetic mat for placing behind map sheets and serves as an adhesion substrate for a magnetic pointer which is already known. It is adaptable and adjustable. As desired, it can be used either as a flexible mat in road atlases (Fig. 2) or - with the aid of the associated clamping rail - as a stable board for folding maps (Fig. 4). Allowance is made for the generally conventional cartographic works, the substrate being universally adaptable to all common types and formats. Special prints are not required. With the invention, motorists travelling alone are in particular able to follow the stretch of road continuously while driving and without stopping, and to mark their current location. They can find their bearings more quickly in unknown areas and immediately determine the right direction to take at critical moments. <IMAGE>

Title: Process for manufacturing green building blocks
IPC: B28B1/44
Filed: 1982-07-15
Abstract: A process is described for the batch manufacture of green building blocks, especially green building bricks, having cavities open at at least one side and penetrating the green block. The green compound is first plasticised with water and then a granular, water-absorbing pore-forming agent is added. It is then filled into a mould corresponding to the size of the block to be manufactured and the cavities are formed in the compound with the aid of so-called swords, the expansion of the compound being restricted with the aid of head plates. In order to deform the compound more easily, especially to be able to manufacture thinner webs, the green compound is overplasticised with the addition of a sufficient quantity of water and the green compound is subjected to overpressure after the penetration of the swords. The plasticising water is then partly absorbed by the pore-forming agent and the compound thereby obtains the higher stiffness necessary for demoulding.
