Title: Liquid flow control system
Inventor: SIMMEL THOMAS L
IPC: B65B39/04
Filed: 1991-04-30
Granted: 2002-04-02
Abstract: By employing two independent, separate and distinct flow paths which are controllably sequentially opened during use in a single actuation operation, an error-free, spill-free flame and explosion proof liquid delivery/filling system is achieved. In the preferred embodiment, both flow paths are normally maintained in a closed, sealed configura-tion, requiring an actuation force to controllably, sequentially open the flow paths. In addition, by providing a cooperating, mating liquid transfer assembly, the container on which the liquid delivery/filling system is mounted can be refilled with safety and ease, completely eliminating spillage of the liquid. In this way, a fully integrated, cooperating, liquid flow controlling system is realized.

Title: Transgenic animals, cells and cell lines therefrom, and their use
Inventor: JAT PARMJIT S
IPC: A01K67/027
Filed: 1991-02-20
Granted: 2006-11-28
Abstract: The provision of cell lines from virtually any cell type of the animal body is greatly facilitated by transgenic non-human eukaryotic animals of the invention in which at least some cells have (i) a differentiation inhibiting sequence chromosomally incorporated under the control of a non-constitutive promotor and/or (ii) a differentiation inhibiting sequence which is itself conditionally active. Said genes are chromosomally incorporated under the control of a promotor such that expression of said sequence is normally held below an effective level, thus allowing normal cell development. However, cells taken from said animal may be prevented from completing differentiation to a non-dividing state in tissue culture by activating expression of said sequence.

Title: A detection system for use in an aircraft
Inventor: PRATA ALFREDO JOSE
IPC: B64D45/00
Filed: 1991-04-09
Granted: 2001-06-05
Abstract: A detection system for use in an aircraft which is able to monitor atmospheric conditions ahead of the aircraft, generate an alarm signal if adverse atmospheric conditions exist ahead of the aircraft and generate information which indicates the posi-tion of the adverse conditions so the adverse conditions can be avoided. The system is able to detect the presence of volcanic ash cloud ahead of the aircraft and, if desired, can also be used to detect a high density of sulphur dioxide gas and/or clear air turbulence ahead of the aircraft. The system monitors infrared radiation received by the aircraft, generates intensity signals re-presentative of at least one predetermined wavelength of the ra-diation and compares intensity signals with reference signals or intensity signals of another infrared wavelength. If the results of the comparison which indicate the adverse conditions are pres-ent, an adverse condition warning signal is generated and the de-vice is also able to generate video display signals for producing a video display which indicates the position of the adverse condi-tions relative to the aircraft.

Title: Vital railway signal link with photo-emission means
Inventor: MOKKAPATI CHINNARAO
IPC: G08C23/06
Filed: 1993-04-16
Granted: 1997-03-04
Abstract: A vital railway signal link for passing DC signals between a first terminal location and a second terminal location.  A transmitter at the first terminal location receives a DC input signal and responsively produces a light signal modulated at a preselected frequency.  The light signal is conducted through an optical fiber to the second terminal location.  There, a receiver detects the light signal and produces a DC output signal.  The receiver contains discriminator circuitry preferably including a bandpass filter to prevent light signals other than those modulated at the preselected frequency from giving an output signal.

Abstract: Method and apparatus for densifying an article wherein the article is disposed in a first molten salt pressure transmission medium in a container.  The first medium is heated to a first elevated densifying temperature.  The container is disposed in a second molten salt pressure transmission medium at a second temperature lower than the first temperature. The first medium and the second medium are communicated so that pressure applied to the second medium is transmitted to the first medium.  Pressure is applied to the lower temperature second medium sufficient to densify the article disposed in the first higher temperature medium. Following densification of the article, the container is removed from the second medium.  The method and apparatus are especially useful for closing internal porosity of metallic and intermetallic castings.

Abstract: A method of destroying organic waste in a bath of molten metal and slag contained in a vessel (3) is disclosed. The method comprises injecting organic waste into the bath to form a primary reaction zone (13) in which the organic waste is thermally cracked and the products of the thermal cracking which are not absorbed into the bath are released into the space above the surface of the bath. The method further comprises injecting an oxygen-containing gas towards the surface of the bath to form a secondary reaction zone ( 17) in the space above the surface of the bath in which the oxidizable materials in the products from the primary reaction zone (13) are completely oxidized and the heat released by such oxidation is transferred to the bath. In order to facilitate efficient heat transfer from the secondary reaction zone (13) to the bath, the method further comprises injecting an inert or other suitable gas into the bath to cause molten metal and slag to be ejected upwardly from the bath into the secondary reaction zone (17).
