Title: Open frame traction system
Inventor: GRANBERG ELOF
IPC: A61H1/02
Filed: 1987-02-03
Granted: 1992-06-16
Abstract: OPEN FRAME TRACTION SYSTEM ABSTRACT OF THE DISCLOSURE A portable traction system includes an open frame for mounting directly on a bed, treatment table, or the floor.  A tension-applying mechanism is mounted on the frame and attached to a cervical tension cord and a pelvic tension cord.  The cervical tension cord is threaded to one end of the frame and extends upward on a vertical post, allowing the patient to undergo cervical traction.  The pelvic traction cord extends to the opposite end of the frame and is connected to a pelvic traction belt which goes around the patient's waist.  The patient wears a counterbelt attached to the first end of the frame, and may use the system to undergo pelvic traction.  Use of the system does not require specialized mounting equipment, and may be utilized by simply placing the frame on a bed, treat-ment table, or other surface.

Abstract: LOCAL AREA NETWORK WITH BIASING ARRANGEMENT  FOR FACILITATING ACCESS CONTENTION BETWEEN  WORK STATIONS CONNECTED TO A COMMON BUS            Abstract A local area data distribution system includes a plurality of data processing stations connected to a common bus. Individual data processing stations contend with each other for access to the bus while the bus is held at a predetermined and controlled but overridable logic state by applying their priority code bit by bit to the bus and comparing the logic state of the bus with the bit they are applying thereto. A biasing arrangement holds the bus at the predetermined and controlled logic state during the contention interval at a signal level that may be easily overridden by an output of any one of the individual data processing stations.

Title: Optically bistable device
Inventor: MILLER ALAN
IPC: G02F1/21
Filed: 1987-09-01
Granted: 1990-12-11
Abstract: ABSTRACT An optically bistable device comprises a Fabry-Perot etalon containing intracavity liquid crystal material. Etalon mirrors of deposited silver are overlaid on indium tin oxide electrodes.    The electrodes provide electrical biassing means for the material, which exhibits both optical nonlinearity and electro-optic tunability of refractive index. The etalon has an interference fringe maximum at a wavelength .lambda.ml. The fringe is tunable to .lambda.m2 by applying a bias voltage across the mirrors. A light beam illuminates the etalon, the beam having a wavelength .lambda.s where .lambda.m2 is between .lambda.s and .lambda.ml. The beam intensity is sufficient to induce bistable etalon switching for a fringe at .lambda.m2 but not for a fringe at .lambda.ml. Tuning the etalon fringe electro-optically from .lambda.ml to .lambda.m2 initiates optical bistability without the prior an requirement of either variable light intensity or an external electrical feedback loop.

Granted: 1997-01-21
Abstract: DNA sequence elements which affect anaerobic induction of genes in plants are identified and characterized.  These sequence  elements,  designated anaerobic  regulatory elements,  confer inducibility by anaerobic condition on downstream plant-expressible promoters and their associated structural  genes.  In  particular,  those  sequences associated with anaerobic induction of the maize alcohol dehydrogenase  and  aldolase  genes  have  been  identified.   These sequence elements can be employed in combination with appropriately positioned plant-expressible genes to product chimeric, anaerobically inducible genes.   Such constructs are useful for the selective expression of structural genes under anaerobic conditions in plants.

Granted: 1993-09-28
Abstract: ABSTRACT         An apparatus especially suitable for cooking, in a cooking fluid, food products which lose a portion of their moisture content as vapor during the cooking cycle is provided.  The apparatus is configured to allow food prod-ucts to be spaced and oriented in the apparatus so that during cooking water vapor is expelled from the food prod-ucts into the vertical convection channels formed by the spacing and orienting of the food products.  The expelled buoyant water vapor augments the upward vertical convection of the cooking fluid through the vertical convection chan-nels, thereby improving heat transfer from the cooking fluid to the food products.  As a result, cooking time and fat uptake is reduced and a more uniform product quality is provided.

Patent CA-1325878-C (CA)
Inventor: GUENKEL ALFRED
IPC: C01B21/44
Filed: 1989-01-26
Granted: 1994-01-11
Abstract: ABSTRACT OF THE DISCLOSURE The invention provides integrated continuous processes for concentrating "weak" nitric acid and concurrently reconcentrating the spent dehydrating agent used to break the nitric acid azeotrope to obtain "strong" nitric acid, the processes involving direct coupling of the nitric acid concentration with the reconcentration of the spent dehydrating agent so that less energy input is required than in equivalent prior art processes.  The major proportion of the feed "weak" nitric acid is vaporized before being fed countercurrently into a column to contact a large volume of the dehydrating agent, this vaporization being one of the two major sources of energy input, the second being through the reboiler at the bottom of the column.  Energy input is balanced by energy rejection through condensation of strong nitric acid vapor and water vapor.  The nitric acid vapor injected into the lower part of the column is subsequently contacted in succession with a mixture of nitric acid and a portion of the dehydrating agent to further increase the strength of the nitric acid vapor, then with a third portion of the dehydrating agent and finally a small reflux of concentrated "strong" nitric acid to remove further water and residual dehydrating agent from the concentrated "strong" nitric acid vapor in the upper part of the column.  The spent dehydrating agent is reconcentrated by flashing under vacuum or alternatively through evaporative cooling with air without further substantial energy input, and is recycled back to the nitric acid concentration column without being cooled, avoiding consequent rejection of energy.  The preferred dehydrating agents are aqueous solutions of sulfuric acid and of magnesium nitrate.
