Title: Antisense gene systems of pollination control for hybrid seed production
Inventor: ARNISON PAUL G
IPC: C12N9/12
Filed: 1989-02-03
Granted: 2002-03-12
Abstract: A process is described for producing hybrid seed using male-sterile plants created by employing molecular techniques to manipulate antisense DNA and other genes that are capable of controlling the production of fertile pollen in plants. Transformation techniques are used to introduce constructs containing antisense DNA and other genes into plants. Said plants are functionally male-sterile and are useful for the production of hybrid seed by the crossing of said male-sterile plants with pollen from male-fertile plants. Hybrid seed production is simplified and improved by this invention and can be extended to plant crop species for which commercially acceptable hybrid seed production methods are not currently available.

Abstract: A "digital" valve comprises a plurality of shutters (46) connected in parallel between an inlet duct (2) and an outlet duct (42) of the digital valve, with each shutter (46) being constituted by an elementary spherical plug valve (50) capable of transmitting an individual flow rate. These shutters are distributed angularly around the axis of the digital valve and each of them is incorporated in a module (24) received in a standard seating (14, 18), thereby making it easy to remove any of the modules. The invention is particularly applicable to rapidly changing over between different flow rates of a liquid or a gas under the control of a digital electronic system (70).

Abstract: A method and system is described for sensing an abnormality in a degassing flow path of a vacuum die casting machine. When a vacuum device is operated to degas a gas in a cavity of a mold, a gas speed flowing through a piping is detected. The gas speed thus detected is compared with the predetermined maximum proper air speed value to determine whether the maximum gas speed value falls into the tolerance limits of the maximum proper air speed value or not. In this comparison, when the detected value departs from the tolerance limits, it is regarded that a clogging has occurred in the degassing system and an alarm is issued.

Title: Sealing enclosures against electromagnetic interference
Inventor: SMITH KEVIN
IPC: E06B5/18

Granted: 1993-05-18
Abstract: ABSTRACT OF THE DISCLOSURE     A sealing arrangement for sealing a door or other closure against leakage of EMI (electromagnetic interference) from an enclosure comprises a flexible strip overlying a peripheral portion of the door.  The flexible strip is attached to the door along its innermost edge.  A magnet strip or the like urges the flexible strip into contact with the enclosure to be sealed. The magnet strip may be mounted on the closure, and trap the flexible strip against the frame, or be mounted upon the frame and pull the flexible strip onto the frame.  Protuberances at intervals along the flexible strip provide reliable electrical contact between the flexible strip and the enclosure.  The closure need not be a door, supported using hinges, but might be a panel supported  solely  by  adhesion  of  the  magnet  strip  to  the enclosure.  A plurality of such panels might be used to clad, and seal, an equipment rack of the open-framework kind. Electrical contact between adjacent panels may be by way of a contact member mounted on the frame, or by direct contact between the panels.

Abstract: ABSTRACT OF THE DISCLOSURE            In  a  gas  laser  exited with pulsed microwave energy, a running gas discharge is generated in a waveguide, this discharge placing the gas in its excited condition, and expiring after migrating through the waveguide.  The microwave energy is supplied at one end of the waveguide, and a short-circuit element is disposed at the other end of the waveguide, with an igniter attached in proximity to the short-circuit element so that the gas discharge, and thus the excitation of the laser gas always begins at the end of the waveguide at which the short-circuit element is disposed.  This structure is especially suited for CO2 lasers.

Abstract: A process for the manufacture of chemi-mechanical pulp from hardwood for wood-containing printing paper, especially wood-containing fine paper, is disclosed.  The wood material in the form of chips is impregnated in one or two steps at a temperature below 80°C with 15 to 40 kg NaOH and 0 to 30 kg Na2SO3 per ton pulp.  Thereafter the chips are refined under pressure, so that the temperature of the chips prior to the refining does not exceed 80°C for a time longer than ten seconds.  The pulp is then bleached with peroxide, at which bleaching at least 15 kg NaOH per ton pulp is charged additionally, so that the total amount of NaOH charged is 30 to 80 kg per ton pulp.  After the bleaching a second refining step is carried out.  The process can be carried out with simple equipment and is characterized by reduced consumption of chemicals and electric energy without deteriorating the pulp quality.

Abstract: The hoist clamp has a coupling eye (7) which has a gimbal-type connection by means of the shafts (5,6) to clamp operating crank (14). When a diagonal pull is exerted, the neck (42) of the coupling eye (7) engages against a bracing point (3,4) which is sufficiently high above the shaft (6) to ensure that the lever action provides extra clamping force between the clamps (11,12). When the coupling eye (7) swings about the shaft (5), the coupling eye engages against the upper edges (1,2) of the casing (8), said edges curving outwards, so that additional clamping force is also obtained when the pull exerted is diagonal. Said additional clamping force is only marginally affected by the load (32) held in the load aperture (37).

Abstract: The invention relates to a prefabricated concrete component system for forming ground-bearing stairways, platforms, terraces and analogous structures of one or more layers. It is the object of the invention to be able to construct, from a few basic components, a durable and safe ground-bearing structure of the desired shape. Such a component system comprises at least three different basic components (1, 2, and 3), which are used together or separately and which are slab components provided with upright supports. The basic components of the component system according to the invention are so designed that one or two adjacent slab components in the same constructional layer form at least two support and fastening surfaces for the next higher slab component. Thus a sturdy and safe structure is obtained. The shape of the components enables them to be cast in a single-part casting mold, from which the component will detach owing to beveled surfaces. The system also includes ramp components, edge components provided with edges, and corner components.

Abstract: A method for assay for an unknown enzyme suspected to be present in a liquid includes signal amplification by use of a second enzyme and a blocked modulator for the second enzyme. Unknown enzyme in the liquid removes a blocking group from the blocked modulator. The resulting modulator activates or inhibits the second enzyme which catalyzes an indicator reaction in which a substrate is converted to a product. The presence or absence of the unknown enzyme in the liquid is indicated by a signal, such as a color change or a rate of color change, associated with the indicator reaction. The concentration of the enzyme in the sample may be determined by the measurement of the signal. The invention includes a kit of materials useful for performing the method of the invention.

Abstract: A recombinant-DNA mediated method for the synthesis of sugar nucleotides is disclosed. This method utilizes portable DNA sequences capable of directing the microbial synthesis of various enzymes that catalyze the synthesis of sugar nucleotides, including UDP-glucose, UDP-glucuronic acid and GDP-mannose. The sugar moieties of these sugar nucleotides may subsequently be incorporated into industrially-useful polysaccharides such as xanthan gum. It has been found that vectors containing the portable DNA sequences described herein are capable both of causing sugar nucleotide production in microorganisms previously incapable of such synthesis and of causing increased sugar nucleotide production in organisms capable of synthesizing small quantities of these compounds. In particular, plasmids pAS7, pAS9 and pTS13 are disclosed. These plasmids are capable of directing sugar nucleotide synthesis in various hosts, including Xanthomonas sp. such as X. campestris and other organisms such as E. coli and various Pseudomonas sp.
