Abstract: A transmitter for converting a binary digital signal into a pseudo-ternary signal at first and second output nodes (40, 41) to form differential output voltages includes a current source amplifier circuit (10), a first voltage source amplifier circuit (12), and a second voltage source amplifier circuit (14). The current source amplifier circuit (10) is responsive to a reference current for generating a first drive current and a second drive current. The first voltage source amplifier circuit (12) is responsive to a reference voltage, a first digital control signal, a second digital control signal and the first drive current for driving the first output node (40) to the reference voltage when the second digital control signal is at a high logic level and for driving the first output node (40) to a ground potential when the first digital control signal is at a high logic level. The second voltage source amplifier circuit (14) is responsive to the reference voltage, first digital control signal, second digital control signal, and sec and drive current for driving the second output node (41) to the reference voltage when the first digital control signal is at a high logic level and for driving the second output mace (41) to the ground potential when the second digital control signal is at a high logic level. The transmitter has been designed so as to overcome the problem of line clamping during a power-dawn condition, provides a current limiting function, and reduces the ringing problem associated with driving an inductive load with a high impedance source.

Abstract: A stereolithography method and system for producing three-dimensional plastic objects by forming a plurality of thin layers of partially cured plastic material which are thin cross sections of the desired object. A layer of polymerizable resin is applied to a support surface and the excess is struck off, such as with a doctor blade, to form a smoothed layer. The smoothed layer is subjected to radiation in a predetermined pattern to form the cross-sectional layer into the desired shape. A plurality of layers are subsequently applied, leveled, then cured in the same manner to produce the desired three-dimensional object. Apparatus for measuring the level of the surface of a fluid is also provided. Variations in the level of fluid will be detected and may be used to drive a pump, diaphragm, or plunger in order to maintain the level of the fluid.

Title: Wound current transformer
IPC: H01F38/30
Filed: 1989-05-10
Granted: 1993-01-27
Abstract: In a wound current transformer a primary winding which penetrates the iron core is provided with a conductive jacket. In the window of the iron core, there is a ring capacitor which abuts the secondary winding, the coatings of which which form the electrodes and are situated on different sides of the ring capacitor are provided with electrical connection lines. In this current transformer, a change of the division ratio is only possible by connecting in parallel an external capacitor, which is relatively costly. In order to be able to set the division ratio without an additional, external capacitor, there are conductive, cylindrical layers (15, 16) in the wound current transformer between the coatings (14, 19) of the ring capacitor (10), said layers extending, with coaxial alignment, at least over a part of the length of the ring capacitor (10) and being connected to the connection lines (17, 18). The transformer can be used as a combined current and voltage transformer. <IMAGE>

Abstract: Transdominant repressors of viral gene phenotypic expression derived from the rev gene product of HIV-1 or the rex gene product of HTLV-1 and corresponding mutated genes are described', having the capability of repressing the Rev function in HIV-1 and/or the Rex function in HTLV-I and HTLV-II. Transient gene expression analysis of a series of missense and deletion mutants has been used. Some of the mutants found repress both the Rev and the Rex function and are thus active in more than one viral species. Transdominant viral mutants represent a promising new class of anti-viral agents. Cellular expression of these transdominant inhibitors may be used in such therapeutic approaches as intracellular immunization in order to protect cells against the deleterious effects of viral, e.g. HIV-1 infection.

Abstract: A self-drilling plastic anchor installable in a wall (18) by means of a screwdriver, the anchor being adapted to receive a threaded fastener (19) that serves to hold a fixture (20) or other object against the wall. The anchor includes an externally-threaded shank section (14) having an enlarged head (15) that is engageable by the screwdriver and a cavity to receive the fastener. Extending from the lower end of the shank section is a drill section (11) that terminates in a point (P) that lies on the longitudinal axis of the anchor. When the anchor is applied to the wall, the point penetrates its surface, so that the anchor may then be turned by the screwdriver about the point. The drill section is formed by a pair of cutting blades (16A, 16B) on opposite sides of the anchor axis and a pair of guide blades (17A, 17B), each angled relative to a respective cutting blade. When the anchor is turned in, the cutting blades guided by the guide blades proceed to bore a hole in the wall, and when the shank section enters the hole, its bank is tapped by the threading of the shank section until the head thereof engages the surface of the wall to complete the installation. The fastener may then be screwed into the cavity of the shank section. The undersurface of the head has ratchet teeth (T) formed therein which when the head engages the wall surface, the teeth grip this surface to resist turning out of the anchor.

Title: Process for drying sludge
Inventor: GREEB HERBERT
IPC: C02F11/13
Filed: 1991-05-17
Granted: 1994-08-10
Abstract: Process and apparatus are described for drying sludge, in which process the sludge in a vessel (1) is conducted from top to bottom by means of a loading device (2, 6, 8) and by means of a discharge device (3, 11) in the form of a sludge column with stable layers and is dried in the course of this in countercurrent by means of drying air entering at the bottom of the vessel through a ventilating base (16) furnished with orifices and leaving from the top of the vessel. The heat contained in latent and sensible form in the drying air conducted away from the vessel is transferred via a heat exchanger (13) to the drying air supplied from outside, so that the heat liberated during the drying on account of the remaining putrefaction process is sufficient to maintain the sludge in the vessel at elevated temperature. Part of the dried sludge removed from the bottom of the vessel (1) is mixed with the externally (2) supplied sludge by means of a mixing device (7), in order to adjust the initial consistency and moisture content. According to a particular embodiment of the invention, a second vessel of essentially the same type is provided, to the bottom of which can be supplied drying air withdrawn from the top of the first container and mixed as required with drying air directly supplied from the surroundings. The sludge to be dried can be initially fed to the first or the second of the two vessels and there subjected to a predrying and then transferred from the bottom of this to the top of the other vessel in each case and there subjected to a final drying. <IMAGE>

Abstract: Rotary impact drilling devices possess, as main components, an impact mechanism and a rotary mechanism, which can be operated individually or jointly as a function of the working conditions. To prevent unnecessary wear in particular on the impact piston and its sealing elements during purely rotary operation, the use of a stop element (31) is proposed, by means of which the impact piston (3) can be lifted off from the tool-insertion end (12) after the impact mechanism (1) has been switched off. The stop element (31) displaceable in the longitudinal direction of the impact piston is constructed and controlled in such a way that it assumes, as a function of the influenceable pressurisation, either an impact-operating position which is displaced in the direction of the impact-piston tip (3a) and in which the impact piston (3) can act on the tool-insertion end (12), or is displaceable, when subjected merely to a control pressure, in the direction of the return-stroke movement (arrow 21) of the impact piston (3) to such an extent into a rotary-operating position that the impact piston is gripped, carried along and thereby freed from the tool-insertion end (12). <IMAGE>

Abstract: Methods for treating surfaces with lipase to provide an enzyme-surface complex and surfaces so treated facilitate oil removal. One such treated surface is a fabric with lipase sorbed onto the surface. A preferred sorbed lipase is isolatable from a Pseudomonas organism or clone. Treated fabrics have substantial hydrolysis activity for oil stains and perhydrolytic activity for oil stains, have altered surface wettability, and retard oil and hydrolysis by-produce redisposition in the presence of aqueous solutions. The sorbed lipase is resistant to removal during fabric laundering and retains substantial hydrolytic activity even with exposure to drying at elevated temperature. The hydrolytic activity of the lipase-fabric complex persists during storage or wear. Hydrolysis by-products are removable during laundering at basic pH or in the presence of surfactant.

Abstract: An automated interrupt driven system which employs a circular buffer is used to sort materials based on differing electromagnetic radiation absorption and penetration characteristics. The system has a conveyor and a source of electromagnetic radiation which radiates materials travelling along the conveyor. A controller samples detector outputs at various times to evaluate the absorption and penetration characteristics of the materials to be sorted, based on a plurality of samples. Portions of the materials are ignored to obtain accurate readings from the detectors. Based on the detected penetration and absorption characteristics, the controller activates ejection mechanisms causing materials of different compositions to be deposited into different bins. The controller executes interrupts to cause detection, ejection, testing, and system history maintenance at required times. The circular buffer contains indices which point to various locations which are programmed in memory to trigger and perform specific events. The location of the indices in the circular buffer is used to control event timing, such as activating and deactivating the ejection mechanisms. This configuration allows several events to be executed simultaneously by moving to the next location in the circular buffer while the event indicated by the index in the previous location continues in progress.
