Abstract: A method and an apparatus for applying molten wax to one face of a wafer(W) is disclosed. A container(11) having an upwardly facing opening contains the molten wax. The wafer (W) is held substantially horizontally above the opening of the container (11), with one face of the wafer (W) facing downwardly toward the opening of the container (11). At least one of the container (11) and the wafer (W) is moved toward the other to bring the opening of the container (11) and underside of the wafer (W) into contact with each other to thereby apply a predetermined amount of molten wax within the container (11) to the underside of the wafer (W). Preferably, the container (11) is filled with the molten wax such that the molten wax stands up, under surface tension, above a peripheral edge of the opening of the Container (11). Preferably, the wafer (W) is spinned around its central axis in a high speed so that the molten wax applied at the central portion thereof is spread on the entire surface of the wafer (W) and that the extra wax is scattered off the wafer. Preferably, walls surrounding the spinning wafer (W) are heated at a temperature higher than the melting point of the wax so that the wax spinned off the wafer may not scatter in the air as particles.

Abstract: A liquid crystal display has a matrix of pixels 1 each with a continuously clocked counter 2, used both as the data store and as the mechanism of grey scale generation. The grey level of each pixel 1 is stored as the phase of the counter 2 with respect to a reference count. 
     The data bus 3, load clock 4, counter clock 5 and master phase reference 6 are all lines which transport signals common to a large number of pixels. 
     The shift data line 7 is used to propagate a bit which enables the counter load input. Each pixel circuit instructs the adjacent circuit that it is next to be loaded, by use of a clock delay 8. Thus pixels are loaded in sequence from data on the load bus 3, that data being changed between load clock pulses. The bistable circuit element 9, set from the master timing and reset from the counter, has an output which directly drives a bistable liquid crystal display device 10.

Abstract: A fall-arrest safety apparatus comprising a cable (5) wound onto a drum (2) has a fixed cable guide (25) and a stop (26) which is secured to the cable (5) near its tail end. The guide prevents passage of the stop under pulling forces exerted on the cable in normal use and thereby ensures that a reserve length of cable remains on the drum. The stop is forced through the guide under the larger pulling force exerted if the worker attached to the cable falls when the stop is against or adjacent the guide.

Abstract: A continuous method for preparing silane and a co-product by reacting a metal hydride such as NaAlH₄ with a silicon halide such as SiF₄. The method involves a reactor loop comprising a primary reactor, a secondary reactor and a separation zone. Most of the metal hydride is reacted in the first reactor to which it is added in a substantially constant rate. The remainder of the hydride is reacted in the secondary reactor, in which all or substantially all of the silicon halide is added. The rate of silicon halide addition is governed by feed back from the reaction in the secondary reactor (ΔT) so that stoichiometric or substantially stoichiometric operation is achieved. This conserves resources, provides improved co-product and reduces costs.

Abstract: Photographic waste solution is treated by a method which comprises contacting the waste solution (3) with air (23), in an especially designed treatment vessel (9), at a solution temperature of from about 120°F. to about 140°F. The air thus becomes supersaturated with the liquid in the waste, and the waste solution is thus concentrated to form a waste slurry which is transferred out into a waste storage vessel (33). The supersaturated air which is virtually free from waste is discharged to the atmosphere. The method is carried out in an especially constructed apparatus comprising a uniquely designed treatment vessel.

Abstract: Dual zone reverse phase packing materials for use in liquid chromatographic blood serum analysis are prepared by contacting a porous support, such as porous silica, with a fluorocarbon silane, such as a perfluorobutylsilyl compound, to form a lipophobic phase in the external zone of the porous support, and, then contacting the porous support with a lipophilic silane, such as an octadecylsilyl compound, to form a lipophilic partitioning phase in the internal zone of the porous support. Ketal blocked diol groups, which later may be hydrolyzed to diol groups are also attached to both zones of the packing materials. The dual zone reverse phase packing materials display a reduced degree of serum protein adsorption in the external zone while drug substances are retained and separated by the lipophilic partitioning phase in the internal zone.

Abstract: Die Erfindung betrifft ein Verfahren zur Herstellung von Polyester- und Alkydharzen aus bi- und/oder höherfunktionellen Carbonsäuren und/oder ihren Derivaten und aus bi- und/oder höherfunktionellen Alkoholen. Die Reaktion wird in diskontinuierlich betriebenen, mit Rektifizierkolonnen ausgestatteten Rührkesselreaktoren durchgeführt. Zur Verbesserung des Transports der Kondensationsprodukte wird während der gesamten Reaktion ein Schleppmittel durch eine Fördereinrichtung unter dem Oberflächenniveau gut verteilt in die Reaktionsmischung eingebracht. Außerdem wird die Kondensationsreaktion mindestens bis zum Erreichen der maximalen Reaktionsgeschwindigkeit unter einem Absolutdruck von 1,5 bis 10 bar ausgeführt. Danach wird in einer zweiten Reaktionsphase der Druck mit einem Gradienten von -0,05 bar/h bis -5 bar/h auf Atmosphärendruck abgesenkt. Die Reaktion wird bei Normaldruck fortgeführt, bis das Produkt die gewünschten Eigenschaften aufweist. Die Reaktionstemperatur liegt zwischen 180 und 320°C. Durch dieses Verfahren werden insbesondere die Prozeßzeiten verkürzt und die dementsprechend thermisch geringer beanspruchten Verfahrensprodukte zeichnen sich durch verbesserte Eigenschaften aus.
