Title: Process for the production of wine without the addition of sulphur products
Inventor: HIESINGER EDWIN
IPC: C12G1/02
Filed: 1990-10-15
Abstract: ABSTRACT            In a process for making wine without the addition of sulphur products, must is extracted in the usual way from pressed grapes; this must is then de-slimed or clarified as required, and fermentation is initiated, if necessary by warming the must and/or by adding yeast and/or by mixing a must that is already fermenting into the new must, when the fermented product is then processed further without the ingress of air.  In place of sulphur products, products that contain starch, such as products from grape pips, preferably grape-pip meal, and elements of the grapes that protect against oxidation, preferably anthocyaninines and/or anthocyanogenes, are added before, during, or after fermentation in order to prevent browning or oxidation.

Title: Casting system for the introduction of a melt
Inventor: SCHNEIDER RALF
IPC: B22D41/08
Filed: 1991-07-24
Abstract: ABSTRACT OF THE DISCLOSURE   The invention relates to a casting system for the introduction of a melt from a first vessel to a second vessel, for example from a tundish into a continuous casting mold, or from a ladle into a tundish. The casting system is simple, compact and suitable for small mold cross sections, particularly with billet formats of about 90 x 90 mm2, in which casting can be effected with the exclusion of air. The casting system has a first vessel which is a ladle or a tundish having a discharge opening, located on the bottom of the vessel, in a closure plane, a second vessel which is a tundish or a mold, an immersion tube, having an end surface, a passage opening on the end surface and a longitudinal axis substantially perpendicular to the end surface, with the passage opening located eccentric to the longitudinal axis of the immersion tube. The immersion tube is arranged below the discharge opening of the first vessel, with the end surface of the immersion tube engaging the discharge opening of the first vessel in the closure plane. The immersion tube extends into the second vessel below the melt level. The immersion tube is fastened, rotatable around its longitudinal axis with respect to the first vessel, so that the end surface of the immersion tube, which adjoins the discharge opening, blocks the flow of melt when the discharge opening and the passage opening are not aligned, and allows a flow of melt when the discharge opening and the passage opening are substantially aligned.

Title: Method of making polarization retaining fiber
Inventor: BERKEY GEORGE E
IPC: C03B37/018
Filed: 1991-11-04
Abstract: Disclosed is a method of making a polarization retaining single-mode optical fiber. Longitudinal grooves are formed on opposite sides of a cylindrically-shaped core preform having a glass core surrounded by cladding glass.       The core preform is inserted into a glass tube, the tube is shrunk onto the core preform, and the interface between the core preform and the tube is fused to form a solid preform having longitudinal apertures on opposite sides of the core. An etchant gas is flowed through the apertures to enlarge the apertures into holes having a substantially round cross-section. Inserted into each aperture is a stress rod formed of glass having a coefficient of expansion different from that of the cladding glass. The resultant draw blank is drawn to form a single-mode optical fiber having a core that is subjected to a stress-induced birefringence.

IPC: H01Q21/24
Filed: 1992-03-04
Abstract: ABSTRACT    A  broadband,   circular  polarization  antenna   is disclosed for use on a satellite.   In one embodiment, signals  are  fed  to,  or  received  by,  an  array  of electromagnetically  coupled  patch  pairs  arranged  in sequential rotation by an interconnect network which is coplanar with the coupling patches of the patch pairs.  The interconnect  network  includes  phase  transmission  line means, the lengths of which are preselected to provide the desired phase shifting among the coupling patches.   The complexity of the array and the space required are thus reduced.  In the described embodiment, two such arrays are employed, each having four patch pairs.  The two arrays are arranged in sequential rotation to provide normalization of the circularly polarized transmitted or received beam.

Title: Fire protection system for rural unheated structures
Inventor: WILSON STEVEN P
IPC: A62C35/00
Filed: 1992-08-06
Abstract: ABSTRACT An economical fire protection system specifically designed for rural unheated buildings. The system features a direct burial water storage vessel that is pressurized by a non-combustible gas. Unlike conventional sprinkler systems, the expense of providing heat to the structure or the use of large quantities of anti-freeze or heavy electrical requirements are eliminated. Burying the water storage vessel below the frost line protects the fire-fighting water from freezing. The use of a check valve interposed between the water storage vessel and the piping connecting the sprinkler heads enables the remaining part of the system to be dry in the readied state. In an alternative embodiment, this piping can be filled with a non-freezable liquid to prevent freezing. Due to the small volume, the amount of anti-freeze required is minimal. The system also features a comprehensive alarm system to warn of system failure or to announce a fire.

Title: Video camera and camera system
Inventor: ISHII SATOSHI
IPC: H04N9/73
Filed: 1992-08-25
Abstract: ABSTRACT OF THE DISCLOSURE      Techniques of a video camera or the like which comprises light emission means  like a strobe illuminating a foreground object, are disclosed. By controlling an amount of strobe light emission means in accordance with a control signal to an AGC amplifier, an image picked-up signal from the AGC amplifier is regulated at a constant level.  A window pattern corresponding to an intended foreground object to be picked up is selected by pattern  selecting means  or automatically selected by colour temperature  information.  Accordingly,  the level of the image picked-up signal of the foreground object is detected so that the strobe is controlled to effect light emission in accordance with illumination intensity on the foreground object. In strobe mode: when a condition for strobe light emission is ready, the aperture of an iris is reduced and the gain of an AGC amplifier is fixed at a predetermined value.  Accordingly,  a dark image representing the condition ready for strobe light emission is displayed  on  an  electronic  viewfinder,  and  in  addition saturation  of charge accumulation  is prevented.  Since white balance of an image picked-up signal of foreground object being picked  up  with  light  emission  of  light  emission  means  is controlled in accordance with colour temperature information, the  effect  of  other  sources  of  light  besides   the  light emission means is taken into consideration.
