Title: Method and system for controlling angular accuracy in optical sensing arrays
Inventor: BLAU DAVID
IPC: G01V8/20
Filed: 1994-11-02
Abstract: An optical sensing array and method of operation for controlling the acceptance angle of light beams which are iteratively strobed in side-by-side channels between light transmitters and light receivers. The light beams in at least a pair of channels are directed along axes which are intentionally mispointed or squinted. A control circuit measures the amplitudes of signals produced responsive to light being received by the light receivers and compares the ratio of those amplitudes to the ratio of predetermined high and low amplitude values which provide a threshold window. When the ratio of the signal amplitudes exceeds the ratio of the window threshold values, an output signal is produced indicative of an unsafe operating condition. The control circuit further maintains the gain of the signals from the light receivers to stay within the range of the predetermined window threshold values.

Inventor: FARR SPENCER B
IPC: C12Q1/68
Filed: 1993-07-06
Abstract: This invention provides methods and diagnostic kits for determining the toxicity of a compound. The methods and diagnostic kits of this invention employ a plurality of bacterial hosts, each of which harbors a DNA sequence encoding a different stress promoter fused to a gene which encodes an assayable product. Each of these stress promoters is induced by exposure to a different type of cellular stress. The stress promoters utilized in this invention, in toto, comprise those promoters which respond to redox stress, DNA stress, protein stress, energy stress and pH stress. The methods and diagnostic kits of this invention may be employed to characterize and quantify the toxicity of a compound, as well as to identify the cellular mechanism of its toxic action. Moreover, the methods of this invention yield information concerning the action of a compound on a subcellular level. This information may be utilized to design antitoxins to compounds found to be toxic and in active drug design.

Patent CA-2156846-A1 (CA)
Title: Method of ensiling fodder
Inventor: PIEPER BERND
IPC: A23K30/15
Filed: 1994-02-18
Abstract: The aim of the invention is to provide a method of ensilage  of  fermentable  agricultural  products  intended principally for use as animal feeds,  conservation being mainly due to lactic acid produced by lactic bacteria in the ensilage product. The requirements for adequate lactic-acid formation depend on the survival and reproduction needs of the cold milk bacteria used. These needs include adequate quantities   of   fermentable   carbohydrates,   anaerobic conditions and relatively low temperatures.The fermentable carbohydrates,  atmospheric  oxygen  and  temperature  are closely dependent  on  each other.  The process  by which fermentable carbohydrates are used up by the breathing of aerobic microorganisms and by plant parts which are not yet dead causes an increase in temperature which degrades the living conditions of the cold milk bacteria and enhances those  of  pests,  thus  causing  high  losses.  The  method proposed is designed to avoid these disadvantages. To obtain good ensiled product, it is necessary for adequate quantity of lactic acid to be produced as rapidly as possible and for sufficient lactic acid to remain during the whole period of storage of the ensiled product. Thus solid carbon dioxide is added to a quantity of ensiled product which is large enough for  it  to  be  influenced  only  little  by  the  ambient temperature, in combination with adequate amounts, already present or added, of lactic bacteria, plus adequate amounts, already present or added, of fermentable carbohydrates, the addition   of   solid   carbon   dioxide   controlling   the fermentation process in such a way that sufficient lactic acid is formed and losses of ensiled product are low. The invention  is  of  use  in the production of  high-quality ensiled fodder with low losses, the method exhibiting good compatibility with the environment.

Patent CA-2160414-A1 (CA)
Inventor: TUBERGEN GARY A
IPC: G01M3/06
Filed: 1995-10-12
Abstract: An improvement on locomotive bubble-type fuel level measuring systems test or monitors the integrity of the bubble-type pneumatic system by observing the rate of bubble formation, in addition to gauging fuel level. A bubble-type fuel level detection system bubbles a volume of air through a bubble tube.     As air exits from the bottom of the tube, bubbles form in the fuel. These bubbles cause small variations in back-pressure in the tube as each bubble grows in size and eventually breaks free from the opening in the tube. The frequency these variations is proportional to the airflow or bubble rate at the bottom of the bubble tube such that pneumatic leaks or other problems can be detected by declaring a problem condition if the bubble rate falls below a predetermined threshold.

Title: Hydroprocessing catalyst and its use
Inventor: IYER PRADEEP S
IPC: C10G49/04
Filed: 1994-09-29
Abstract: A catalyst containing an overlayer of a catalytic promoter on a porous refractory support containing an underbedded Group VIII metal-containing component. The catalyst is prepared by sequential incorporation of the Group VIII metal followed by the additional catalytic promoter component, usually a Group VIB metal, with the porous refractory oxide support. Underbedded nickel components on the catalyst are characterized by a unique Raman spectrum exhibiting Raman bands in the region of about 240 cm-1 to about 250 cm-1 and in the region of about 595 cm-1 to about 605 cm-1. The catalyst has a MoO3/NiO  weight ratio less than 6 to 1 and more than 4 weight percent of NiO. The catalyst is prepared by first producing a calcined particulate containing a group VIII metal component and a refractory oxide and, subsequently, adding a promoter, such as a group VIB metal component, and then recalcining the so obtained particulate composition. Preferred promoters are molybdenum and phosphorous compounds. The preferred composition is Ni-P-Mo oxides on alumina.  The catalyst is especially useful for simultaneous hydrodenitrogenation and hydrodesulfurization of a gas oil, particularly when the refractory oxide support has a narrow pore size distribution.

Abstract: A computerized, interactive system to search for and identify possible real property equity exchanges in-volves the establishment of a data field in an electronic data base (54) to enable a user to develop, locate and identify property trade scenarios (50). A computer is utilized to process data from a plurality of sources, each providing specifics of the owner's exchange desires and the current property's characteristics.  The computer re-views trade location desires of the property owner and finds the potential trades from the location of other trad-able properties (56). There need not be a direct match or a reciprocal match between two properties for a possible property exchange to be identified. The system allows identification of exchange scenarios involving many dif-ferent properties, wherein the exchange scenarios can be circular or open ended.
