Abstract: Chitin, a widely occurring natural material, is converted into a polymeric substance of amphoteric nature and useful as an adsorbent material, in for example, the separation of sugars and proteins or of mixtures of proteins, by successive cross-linking, carboxyalkylation and deacetylation reactions. The resulting cross-linked polymeric substance has a degree of cross-linking of 0.01 to 0.3, a degree of carboxyalkylating substitution of 0.1 to 0.9, and a degree of deacetylation of 0.1 to 1.

Abstract: Air conditioning apparatus (3) has a compressor (6), a condensor (7), an evaporator (8), an expansion valve (9), a blower (10) and a pump (11). 
     Cooling water from outdoor cooling tower 4 is passed to the condensor (7). Air circulating in computer room (1) passes evaporator (8) of the air conditioning apparatus (3) to be cooled. 
     A cold water switching valve (12) is provided for diverting cooling water supplied by tower (4) from condensor (7) to a cold water coil (13). 
     When the outside temperature is low enough to give sufficiently cold cooling water, valve (12) is operated to divert cooling water from the condensor (7) to the cold water coil (13), the compressor (6) is switched off and air circulating in the computer room (1) is cooled by cold water coil (13), instead of evaporator (8).

Abstract: 1. Sliding gate valve, consisting of a shutter plate (2) moving in translation between two fixed side plates (1) which form the body of the valve and which each have an opening (11) capable of being masked or uncovered by the plate (2), the said shutter plate (2) being mounted so that it slides between the side plates, and being guided by its lateral edges within slides (5) which are integral with the side walls, members (3) being interposed between the slides (5) and the moveable plate (2) filling all the space within the said slide in order to prevent the product passing through the valve and penetrating into the slides and accumulating there, the valve being characterised by the fact that the said shutter plate (2) is fixed between two members (3), in the form of elongated strips which are firmly connected to it and which have a length greater than that of the plate, this length being such that the said members (3) still extend beyond the opening (11) when the valve is in the open position, and by the fact that the internal edge (13) of the active part of the plate (2) is semi-circular, so that when the valve is in the closed position, this edge (13) comes into contact with a fixed stop (4) clamped between the side plates (1), the upper edge of which (14) is also semi-circular in shape, complementing that of the edge (13) of the plate, the latter coinciding with the edge of the opening (11), so that at the edge of this opening the side wall (1) and stop (4) assembly does not form any channel or transition.

Title: Work piece powder coating installation including a cabin to temporary receive the work piece.
Inventor: VOHRINGER GERHARD FRIEDRICH
IPC: B05B14/48
Filed: 1980-11-27
Abstract: A booth forming a spraying chamber for workpieces to be coated with powder particles has a substantially fully open front side, giving access to an electrostatic spray gun, and a substantially fully open rear side adjoining a housing of a detachable powder-collecting unit which is open toward the chamber while being separated therefrom by an apertured screen. Tubular filter elements in the housing of the powder-collecting unit, having air-permeable peripheral surfaces, communicate with the suction end of a blower in an overlying clean-air unit, thereby giving rise to an air stream which passes generally horizontally through the chamber from its front side to its rear side and entrains particles discharged by the spray gun. Particles bypassing the workpiece to be coated may traverse the apertured screen and cling to the surfaces of the filter elements from which they may be intermittently dislodged by an air blast directed into these elements from the clean-air unit. The dislodged particles fall into a recovery compartment of the housing which lies below the level of the chamber bottom, this bottom sloping down toward the recovery compartment whereby particles dropping to the chamber floor can slide directly into that compartment underneath the apertured screen. A flexible conduit connects the recovery compartment with the spray gun for recirculation of the particles which, after passing through a strainer, are reconditioned by a fluidized bed in the recovery compartment. Cutouts in the sidewalls and a slot in the roof of the booth enable the introduction and withdrawal of workpieces suspended from above.

Abstract: Zum Angleichen der unterschiedlichen Signalverzögerungszeiten der Logik-Gatter verschiedener Halbleiterchips ist auf jedem Halbleiterchip eine Regelschaltung (4) für die Signalverzögerung vorgesehen. Ihr wird als Bezugssignal ein externer, allen Halbleiterchips gemeinsamer Taktimpuls zugeführt. Die Regelschaltung vergleicht dessen Phasenlage mit der eines Impulszuges, der von einem zur Regelschaltung gehörenden spannungsgesteuerten Oszillator geliefert wird. Die als Vergleichsergebnis erhaltene und verstärkte Spannung beeinflußt den spannungsgesteuerten Oszillator, bis die beiden Impulszüge synchronisiert sind. Die verstärkte Spannung wird auch den Logik-Gattern zugeführt. Sie verändert deren Aufnahme von elektrischer Leistung so, daß die gewünschte Signalverzögerung, die eine Funktion der elektrischen Leistung ist, erreicht wird.
