Title: Improvements in molten metal handling vessels
Inventor: BROMS GUNNAR
IPC: B22D1/00
Filed: 1993-03-22
Abstract: The invention provides a means of introducing gas into the outlet to remove an obstruction. Accordingly, the invention provides an apparatus to open and close an outlet in a molten metal handling vessel which includes a valve (6) communicating with the outlet (5a) and having relatively movable valve parts (7, 8), the valve parts having openings (10, 12) which are displaced from one another to close the valve and, hence, the outlet (5a) and which are in communication with each other and with the outlet (5a) to open the outlet, whereby the molten metal can flow out of the vessel, characterised in that there is provided a frangible tube (13) through which gas can be passed, the tube (13) being of sufficient length to extend through both valve parts (7, 8) and into the outlet (5a) of the vessel, whereby gas can be passed into the outlet and then opening of the valve (6) by relative movement of the valve parts (7, 8) breaks the tube (13) so that it does not obstruct opening.

Title: Integrating rules into object-oriented programming systems
Inventor: CRAWFORD JAMES MELTON JR
IPC: G06F9/44
Filed: 1995-10-02
Abstract: Techniques for integrating rules into imperative object-oriented languages such as C++. C++ is extended to permit definition of rules as members of classes. When arule is defined as a member of a class, a preprocessor receives the declaration of the rule's class and of any other class involved in the rule and generates additional data members and member functions for the classes. The additional members of the classes permit a complete implementation of the rule. No additional rule interpreter or decision network is required. The rule definition defines collections of objects linked by interobject pointers to which the rule applies. A rule is evaluated only if there is a change in a value mentioned in the rule in an object belonging to a collection of objects for the rule. The rule's condition is a sequence of bindings and tests. The bindings define a path through a collections of objects to which the rule applies, and the path is followed during evaluation. The rules thus implement access-limited logic.

Title: Multi energy system for x-ray imaging applications
Inventor: RUDICH IRWIN
IPC: G01V5/00
Filed: 1995-03-17
Abstract: In an all electronic multi energy system at least two levels of x-ray energy are produced sequentially and rapidly at independently controllable and different power or flux levels. In the system there are a triode x-ray tube (1) which selects the operating current of the system and a series connected temperature limited diode (2) or triode which controls the voltage across the first x-ray tube. This system provides improved performance in x-ray imaging applications at low cost, for example, in baggage inspection or measurements of bone densities and medical fluoroscopy. The objective of the system is to produce a maximum amount of useful information with a minimum amount of exposure for the patient or object to be illuminated by x-ray flux. With human patients this is desirable for health safety reasons; for baggage inspection, to reduce exposure to photographic films.

Abstract: Known fan controls have a temperature sensor and a humidity sensor that trigger operation of the fan. In the present invention the outputs of the sensors are supplied to a processor that switches on the fan when certain temperature and humidity conditions are met. The processor turns on the fan in response to an increase in temperature and humidity, a larger increase in humidity being required for a smaller increase in temperature. The fan is also turned on when humidity rises above a certain threshold value, which is lower for higher temperatures.

Title: Hydroxyl ions as unique therapeutic agents and compounds that modulate these ions, compositions employing these agents, therapeutic methods for using such agents and processes forpreparing them
Inventor: CARRELL DELTON R
IPC: C07C53/122
Filed: 1994-10-05
Abstract: The invention concerns the discovery of the surprising and unexpected therapeutic effects of hydroxyl ions. The observed medicinal properties of these ions are both novel and broad in scope. The acute corrosive effects and toxicity of hydroxyl ions on living tissue has previously overwhelmed their therapeutic attributes. Unique hydroxyl ion modulating compounds have been discovered and are within the scope of the invention. When used appropriately as companions with hydroxyl ions, these modulating compounds obviate and attenuate the harmful effects of hydroxyl ions,unmasking and revealing their previously unknown and undemonstratable therapeutic properties. These hydroxyl ion modulating compounds do not significantly interfere with the surprising and unexpected therapeutic benefits of the hydroxyl ions. The novel hydroxyl ion modulating compounds are generally characterized as N,N-disubstituted-aminoacetate salts and substituted N,N-substituted-aminoacetate salts. The invention includes compositions and methods of treatment using hydroxyl ions and the companion hydroxyl ion modulating compounds. These compositions and methods of treatment provide a wide variety of therapeutic effects including dermal effects (such as wound healing), ocular effects, oral therapeutic effects, ear, nose and throat therapeutic effects and internal therapeutic effects. Processes for preparing the present hydroxyl ion modulating components are also disclosed and are within the scope of the present invention.

Title: Transmitter and receiver for orthogonal frequency division multiplexing signal
Inventor: SUGITA TAKEHIRO
IPC: H04L27/26
Filed: 1996-05-28
Abstract: In a communication system, the energy of each bit of the inputted information bit string is diffused over the whole frequency band of the orthogonal carriers, and the energy of the plural bits is multiplexed onto each orthogonal carrier, as a result, even though frequency selective fading has occurred attenuation value of the energy of each bit is little, and remarkable degrading of the error rate can be alleviated, and changing of the data rate can be easily accommodated by modifying the number of the code multiplexing. In this way, a communication system can be realized which is able to alleviate the performance deterioration due to frequency selective fading, and to easily cope with a modification of the data rate.
Patent CA-2182075-A1 (CA)
Inventor: GIAN MICHAEL
IPC: G01F11/00
Filed: 1996-07-25
Abstract: A system for applying accurately metered, minute quantities of concentrated additives from bulk sources of supply to successive masses of material presented for treatment includes a pass-through chamber within which separate streams of a liquid carrier and the additive substance are merged together.  As the liquid carrier passes through the chamber, the additive, in either dry or liquid form,  is likewise directed into the chamber in a metered flow to incrementally combine with the liquid stream and form the combined product.  A suction pump at the downstream end of the chamber draws the prepared product out of the chamber and advances it toward an ultimate delivery site.  The carrier liquid is prevented from accumulating  into a pool within the chamber by the suction pump that cooperates with the upright orientation of the chamber to cause the carrier liquid to swirl smoothly through the chamber.  A suction vortex may be created as the product exits the chamber, within which vortex the additive may be directed so as to complete its entrainment with the carrier without causing turbulence.  The system can be easily flushed with the liquid carrier after each batch and then dried with an optional air blower.
