Title: Specific anti-salmonella monoclonal reagents, and unique serological approach for the detection of different common serotypes of salmonella and the like
Inventor: TSANG RAYMOND
IPC: C07K16/12
Filed: 1992-09-14
Abstract: ABSTRACT OF THE DISCLOSURE    The detection and identification of Salmonella using murine hybridoma monoclonal antibodies is disclosed.   A panel of anti-Vi and anti-O specific monoclonal antibodies has  been  successfully  applied  for  the  serotyping  of Salmonella while  anti-lipopolysaacharide  core  specific monoclonal antibodies have been applied for the detection of different common serotypes of Salmonella.   Using a combination of the anti-O and anti-core specific monoclonal antibodies in a sandwich capture ELISA, it is possible to accomplish  simultaneous  detection  and  serogrouping  of Salmonella.  The immunoassay approach for the detection of Salmonella uses multiple time point assay, which measures a rise in the level of the targeted microorganism or its antigens, thereby allowing better differentiation of true positives from non-specific reactions in the immunoassay. This  assay  approach  is  therefore  most  suitable  for immunoassay  of  infectious  microorganisms  as  long  as specific  antisera  or  antibodies  against  the  targeted microorganisms are available.

Title: Absorption vapor pressure enhancement process and its applications in high level refrigeration and separation processes
Inventor: CHENG CHEN-YEN
IPC: B01D8/00
Filed: 1991-02-26
Abstract: This invention introduces an absorption vapor pressure enhancement operation. In the process, a mass of solvent vapor is absorbed into an absorbing solution under a first pressure and an equivalent amount of second vapor is produced under a second pressure that is substantially higher than the first pressure. The pressure enhancement is accomplished by the dilution of the absorbing solution. A vapor pressure enhancement operation (98, 99) applied to a low pressure vapor is functionally equivalent to compressing a low pressure vapor. By using a multiple stage pressure enhancement operation (98, 99), a very high level of temperature lifting of heat can be accomplished. The process can be adopted in processes in which low pressure vapors are generated. Examples are freeze drying processes and multiple phase transformation processes such as Vacuum Freezing Processes, Eutectic Freezing Processes and Distillative Freezing Processes.
Patent CA-2080187-A1 (CA)
Title: Multi-media computer operating system and method
Inventor: CARMON DONALD E
IPC: G06F9/48
Filed: 1992-10-08
Abstract: An operating system for scheduling execution of a random  set  of  periodically  recurring  hard,  real-time tasks   encountered   in   multi-media   computer   system applications  and  which  is  useful  in  a  multi-tasking computer  operating  environment.  Periodically  recurring computer tasks having relatively short execution periods for which execution results are absolutely required in hard, real-time environments such as multi-media systems, create a significant task scheduling overhead reducing the available processor resource.  Overhead processing at task invocation is eliminated in the invention by placing all  active  recurrent  tasks  in  an  execution  queue, regardless of the task s current state of activity and by reprioritizing the order of execution of the tasks in the queue whenever a given task execution is completed. Measured  by  reduction  in  task  scheduling  overhead consumed by the processor in scheduling the tasks, this achieves   a   50-100%   improvement   over   conventional scheduling and operating systems.

Title: Photochromic polymer membrane
Inventor: WASSERMAN NELSON
IPC: G03C1/005
Filed: 1991-04-17
Abstract: A photochromic material adapted for coating light transmissive materials. The photochromic material contains photosensitive silver halide crystals having dimensions in the range of approximately 50 Angstroms to 800 Angstroms. The silver halide crystals are surface doped with copper ions and another sensitizer selected from mild reducing agents, thioethers, or sulfur-bearing ions and are treated with an agent to accelerate the forward reaction and control the reverse reaction. The accelerants are ions selected from the group consisting of cobalt, chromium, manganese, magnesium, and rare earth metals such as cerium, samarium and europium. The agent for controlling the reverse reaction is one that confers electrical conductivity on the material and while to this end glycerol containing a high concentration of metal ions, methane sulfonic acid and benzyltrimethyl ammonium chloride are useful, the preferred agent is phosphoric acid. The crystals are dispersed in one or more protective polymers that do not irreversibly bind halogen.

Filed: 1993-06-09
Abstract: An apparatus and method for plug-assisted thermoforming of a cup or other hollow article has a concave well or cone region machined into its top with a series of small holes drilled near the deepest part of the well and connected to a port inside the plug which is connected to a specifically sized manifold system. The manifold has a source for positive (pneumatic) and negative (vacuum) pressure air. During the machine cycle, a vacuum is introduced into the plug, which draws the hot plastic sheet into the plug well to stretch it. The vacuum is replaced by compressed air to transfer the pre-stretched sheet into a mold. In a particularly preferred embodiment, the plug is shaped to provide stretching in both the central well and in peripheral regions concentric with the well. Controlled air pressure in the mold may be used to provide the concentric prestretching.

Title: Tundish for molten alloy containing dense, undissolved alloying ingredient
Inventor: PIELET HOWARD M
IPC: B22D11/10
Filed: 1993-11-05
Abstract: ABSTRACT       A tundish has an entry location for receiving a molten alloy, such as steel, and bottom outlet openings for withdrawing the molten alloy.  The tundish bottom comprises a sump located downstream of the inlet location and upstream of the outlet openings.  Undissolved, molten alloying ingredient, denser than the molten alloy as whole, (e.g. lead or bismuth in the case of molten steel) accumulates in the sump.  The sump has a floor and passageways which extend downwardly from the sump floor to a drain in the steel tundish shell underlying the sump.  The passageways are permeable to undissolved, molten alloying ingredient but impermeable to the molten alloy.  There are expedients for maintaining the passageways at a temperature which prevents undissolved alloying ingredient descending through the passageways from cooling to a temperature at which the undissolved alloying ingredient blocks the passageways against further passage by undissolved, molten alloying ingredient.
