Abstract: The invention relates to the formation of a uniform layer on a travelling substrate by spraying with a liquid composition. The process consists in spraying the liquid composition onto the travelling substrate by means of a sprayer adapted to move transversely to the substrate at a relative speed in relation to the substrate which has a nil axial component. Using this process, a succession of traces which are parallel to each other and perpendicular to the direction of travel of the substrate is obtained on the substrate. <IMAGE>

Abstract: A process for preparing 15-oxygenated sterols, such as 3β-hydroxy-5α-cholest-8(14)-ene-15 one, comprising converting 7-dehydrocholesterol to 3β-benzoyloxycholesta-5,7-diene, converting the 3β-benzoyloxycholesta-5,7-diene to a 3β-benzoyloxy-5-cholesta-7,14-diene, converting the 3β-benzoyloxy-5-cholesta-7,14-diene to a 3β-benzoyloxy-14α, 15α-epoxy-5-cholest-7-ene and converting the 3β-benzoyloxy-14α, 15α-epoxy-5-cholest-7-ene to a 15-oxygenated sterol. Preferably, the 3β-benzoyloxy-cholesta-5,7-diene is converted to a 3β-benzoyloxy-5-cholesta-7,14-diene by (i) contacting 3β-benzoyloxy-cholesta-5,7-diene, in a solvent at a temperature of at most about -55°C, with HCl at a concentration of at least about 2.0 M for a time sufficient to convert the 3β-benzoyl-­oxycholesta-5,7-diene to a 3β-benzoyloxy-5-cholesta-7,14-diene; (ii) neutralizing the resultant reaction mixture with a base to prevent formation of a significant amount of 3β-benzoyloxy-5-cholesta-8,14-diene; and (iii) recovering the 3β-benzoyloxy-5-cholesta-7,14-diene.

Abstract: In the case of a fuel injection apparatus with an injection nozzle (3) opening at predetermined pressure, to which fuel can be fed under pressure, the injection nozzle chamber (2) is connected to a fuel feed line (8) by way of an outward closing non-return valve (9), the pressure in the fuel feed line (8) being lower than the opening pressure of the injection nozzle. In addition, the injection nozzle chamber (2) is connected to a working chamber (14) of a spring-loaded working piston (12), the displacement movement of which is brought about by the action of the spring force in order to increase the pressure in the nozzle chamber (2) in excess of the opening pressure of the injection nozzle (1) by relieving a separate working chamber (20) of the spring-loaded working piston (12).

Abstract: The present invention uses a scavengeless development system in which toner detachment from a donor (42) and the concomitant generation of a controlled toner powder cloud, is obtained by AC electric fields supplied by self-spaced electrode structures (48) positioned within the development nip. The electrode structure is placed in close proximity to the toned donor within the gap between the toned donor and image receiver, self-spacing being effected  via  the toner on the donor. Such spacing enables the creation of relatively large electrostatic fields without risk of air breakdown.

Abstract: A closure device 14 for a container 12 includes a closure body adapted to fit onto the container thereby to close off an access opening in the container. A dispensing opening is provided in the closure body, and a closure member 35 is slidable along a guide path on the closure body, from a first position in which it closes off the dispensing opening, to a second position in which the dispensing opening is uncovered. A displaceable stop 24 is provided on the closure body so that, when the closure member is in its first position, it is held by the stop against being moved to its second position. The stop hence has to be displaced to permit movement of the closure member from its first to its second position.

Abstract: The present invention involves an optical fiber splicer which is made of a unistructural mass (21c) of inherent shaped memory polymer material. The uni­structural mass has a longitudinal dimension with opposite ends which includes a first bore (25c) at one end and a second bore (29c) at the other end wherein the bores go into the mass and to each other. In a preferred embodiment, the first bore and the second bore are merely a single continuous oriface. The unistruc­tural mass has a first shape and a second shape and the first shape is a unique, recoverable, pre­determined inherent shape wherein the first bore and second bore each have a preset diameter to accommodate and tightly hold end segments of denuded optical fibers (31,35) of predetermined diameter in spliced, butted alignment with one another. The second shape is a deformed shape caused by solvent swelling and partial shrinking of the inherent memory polymer material such that the first bore and second bore each have swollen predetermined diameters which are greater than the diameters of the end segments of the denuded optical fibers so as to loosely and freely receive the end segments of the denuded optical fibers. Thus, the unistructural mass of inherent shape memory polymer material is initially formed in the first shape, also known as the inherent shape, and is then swollen and partially shrunk to its second or deformed shape and is capable of being returned to its first shape by application of a non-mechanical stimulus thereto, such as heat (Fig. 6). The invention is also directed to the method of preparing the optical splicer as well as the method of using the optical splicer to obtain a butt-to-butt splicing of end segments of optical fibers.

Abstract: A transformer coupled amplifier drive circuit (40,60) and method especially suited for providing a saw-tooth current waveform to an inductive load (32) for horizontal deflection applications in CRT monitors and the like are described. 
     When the input switch (44) is closed, the input of the amplifier (26) is energized by a current (45,65) through the series connected primary (48) and energy is stored in the transformer (46) magnetizing field and in the amplifier (26). Conduction in the transformer (46) secondary (50) is blocked by the diode (56). 
     When the input switch (44) is opened, the input charging current (45, 65) stops and the collapsing primary (48) magnetizing field produces an oppositely directed current (47,67) which flows through the secondary winding (50), the diode (56), the series connected inductor (52) and the input to the amplifier (26). The demagnetization energy stored in the transformer (48) cancels the energy stored in the amplifier (26), thereby reducing total dissipation, and the inductor (52) controls the fall time independent of the rise time.

Abstract: The invention provides a static inverter-type TTL/CMOS level translator including transistors (Q2 & Q5) to suppress hot electron effects. The transistors limit maximum VDS to VCC-VTN at the first and second gain stages. Resistors (R1 & R2) serve as a virtual VCC modulator to minimize voltage variations, stabilizing the VIL/VIH trip point. The resistors (R1 & R2) also minimize standby current so that the translator can be used in a low standby current environment. The translator provides faster speed, wider process margins, better reliability and lower standby current than prior art translators.
