Patent DE-3377765-D1 (DE)
Title: Microphone
Inventor: KERN OTMAR DIPL ING
IPC: H04R3/00
Filed: 1983-05-26
Granted: 1988-09-22
Abstract: An electroacoustic transducer system comprises a microphone working into a low-frequency amplifier for the energization of an a-c load such as, for example, a loudspeaker or a volume indicator at a control panel. Biasing voltage for the microphone and operating current for the amplifier are derived from a d-c source, via a phantom circuit including the output leads of the amplifier and through a coupler in cascade with a chopper; the latter includes a transistor conducting intermittently under the control of an adjustable pulse generator whose pulse width is varied by negative feedback from the integrated chopper output. An output transformer with a primary in series with the transistor has several secondaries each connected across a storage capacitor through a diode for the generation of a relatively high biasing voltage for the microphone, a relatively low driving voltage for the amplifier and, possibly, a further voltage used to vary the directional pattern of the microphone. To facilitate the establishment of different voltage levels, the development of the lower voltage is delayed-by the combination of a choke with a Zener diode, or by a thyristor-until the higher voltage has been reached by a transient occurring at the beginning of each cutoff phase.

Abstract: Photochemical reactions are conducted using floating polymer beads on the surface of a moving body of water. The polymer bead is impregnated with a reactant, floated on the water in direct sunlight so as to expose the reactant to solar radiation, collected at a downstream location, treated to remove product from the polymer, and then the bead can be recycled. The process can be used to collect and store solar energy in chemical form, or for conducting photochemical synthesis to produce useful chemical products.

Patent DE-3464518-D1 (DE)
Title: Valve stem packing assembly
Inventor: WILLIAMS PETER CHARLES
IPC: F16K41/02
Filed: 1984-03-21
Granted: 1987-08-06
Abstract: A valve body has a stem passage rotatably receiving a valve stem. A packing surrounds the stem in the passage and a packing nut threaded on the stem applies axial force to radially expand the packing into sealing engagement with the stem and passage wall. Controlled slippage components interposed between the packing and packing nut allow rotation of the stem and packing nut without any rotational sliding movement against an end face of the packing. A packing support ring engages the end face of the packing adjacent the packing nut and includes a chevron surface for radially expanding the packing. A gland engages the support ring and a pair of reversely positioned spring washers are interposed between the gland and packing nut. During rotation of the stem, packing nut and spring washers, the gland rotates against the packing support ring. The chevron surface of the support ring includes notches for gripping the packing to prevent relative sliding movement therebetween. A handle is attached to the stem by a handle nut, and a spring washer interposed between the handle and handle nut prevents loosening of the handle nut.

Granted: 1991-10-02
Abstract: The hub bore on an Al piston is hardened by producing a fibre structure circumferencially around the bore to a depth of at least 0.1mn, pref. 0.2mm. A hub bore is produced of diameter less than the final diameter by drilling. The piston is then rolled at at least 350 deg.C. (pref. over 400 deg.C.) to widen the bore by 0.2-0.5mm. After rolling, the final diameter is produced by removing metal in the deformed area. This also ensures uniform dimensions of the bore cross-section.

Title: Semiconductor device for producing an electron beam
Inventor: VAN DER MAST KAREL DIEDERICK
IPC: H01J1/30
Filed: 1985-01-28
Granted: 1988-08-04
Abstract: In a semiconductor cathode, the electron-emitting part of a pn junction (5) is provided in the tip of a projecting portion (10) of the semiconductor surface (2) which is situated within an opening (8) in an insulating layer (7) on which an acceleration electrode (9) is disposed. Due to the increased electric field near the tip, a reduction of the work function (Schottky effect) is obtained. As a result, cathodes can be realized in which a material (14) reducing the work function, such as caesium, may be either dispensed with or replaced, if required, by another material, which causes lower work function, but is less volatile. The field strength remains so low that no field emission occurs and separate cathodes can be driven individually, which is favourable for applications in electron microscopy and electron lithography.

Abstract: Production of core antigens of the virus HTLV-III and their use in detection of antibodies in sera of AIDS and pre-AIDS patients, and to biochemical and immunological analysis of antigens associated with the virus HTLV-III. The utilization of p24 and p41 core antigens enables a greater specificity of detection. It is shown that antigens associated with the infection of human cells by the virus are specifically recognized by antibodies from AIDS patients. Specifically, HTLV-III isolated from AIDS patients and transformed by occultivation with an HT cell line is specifically detected by antibodies from human sera taken from AIDS patients. The p24 and p41 antigens are used to monitor the precense of HTLV-III in cultured cells and cell-free culture fluids, where virus infection is suspected, and also to monitor antibodies in human sera. The method of detection of antibodies preferred is a radioimmunoassay (RIA), ELISA (an enzyme-linked immuno-sorbent assay) or indirect immunofluorescene assay.
