Title: Method of automatically starting a continuous casting apparatus
Inventor: EGOSHI KAZUFUMI
IPC: B22D11/16
Filed: 1989-11-02
Abstract: ABSTRACT OF THE DISCLOSURE   A method of automatically starting a continuous casting apparatus having a mold, a tundish for temporarily storing therein molten steel for subsequent transfer of the molten steel to the mold, a device for transferring the molten steel from the tundish to the mold, a level measuring device for measuring the surface level of the molten steel in the mold and a device for controlling the quantity of the molten steel to be transferred from the tundish to the mold on the basis of a level value measured by the level measuring device, which comprises stopping the transfer of molten steel from the tundish to the mold once the surface of the molten steel in the mold reaches a predetermined level after the transfer is commenced, allowing the molten steel in the mold to stand as it is for a predetermined period of time thereby to stabilize the surface of the molten steel in the mold, subsequently starting the drawing of a slab formed by means of the mold, and simulataneously resuming the transfer of molten steel from the tundish to the mold to bring the surface of the molten steel in the mold to a steady control level.  According to this method, it is possible to easily carry out automatic starting of the continuous casting apparatus.

Abstract: ABSTRACT OF THE DISCLOSURE A method for testing for glycol contamination in oil, comprising the following steps.  Prepare a water base mixture consisting of 10 milliliters of distilled water, .25 grams of potassium periodate and .25 grams of ammonium chloride.  Add to the water base mixture at room temperature 3 milliliters of well mixed oil.  Agitate the combined oil and water base mixture for a minimum of 15 seconds; the potassium periodate and ammonium chloride act to breakdown glycol present in the oil and water base mixture to form formaldehyde.  Invert the oil and water base mixture and let it stand for a minimum of 5 seconds; it separates into a water layer and an oil layer. Drain the water layer.  Add to the water layer .01 grams of an  indicator  chemical  for  the  detection of  formaldehyde. Agitate the water layer and indicator chemical.  Add to the water  layer 3 milliliters of  .2 molar solution of sodium hydroxide  to  form  an  alkaline  solution  conducive  to  a colourmetric reaction by the indicator chemical.   Let stand for  approximately  1  minute  and  observe  for  colourmetric reaction.

Abstract: Un coffrage préfabriqué et isolant pour fondation de béton comporte des parois interne et externe en matériau rigide et isolant, par exemple formées chacune de panneaux de polystyrène expansé. Une succession de montants espacés les uns des autres sont disposés entre ces deux parois. La paroi interne est fixée sur une première surface des montants tandis que la paroi externe est fixée sur une autre surface de ces mêmes montants, opposée à la première. Un espace vide est donc défini entre les parois interne et externe et chaque paire de montants successifs, chacun de ces espaces ayant une extrémité supérieure ouverte de sorte que l'on puisse y verser du béton. Des tiges d'acier traversent les montants pour passer d'un espace vide à l'autre et ainsi former une armature qui transforme le béton versé en une structure rigide.

Title: Card saver
Inventor: PACEY DONALD G
IPC: A45C1/06
Filed: 1990-08-22
Abstract: ABSTRACT     Magnetic theory states that if something is to be shielded from a magnetic source then it should be surrounded on all four sides. This is consistent with magnetic theory, since it states that magnetic flux will flow around objects in space. It however makes for a very bulky and awkward device that would protect the credit card from demagnetization. In this invention the end of an envelope is open with a notch cut into it for the easy withdrawal of the credit card from the Card Shield. Current magnetic theory states that magnetic flux should find this opening and flow into the envelope, thus destroying the magnetic information inside. However protection is provided for the section of the credit card's magnetic strip that information isencoded upon. The magnetic flux that does reach the open end of the envelope is absorbed by the magnetic shielding material, thus saving the information. This advance in utility helps reduce the size of the shielding device while increasing the usability of the device. By using the plastic spacer in the device, it limits the Card Saver to one unit per card, thus ensuring that scratching of the card's magnetic strip does not occur.          Don Pacey THE CARD SAVER

Abstract: The machine of the present invention measures and records in terms of the orientation planes of motion the presence of, the location, of and the severity of the postural distortion-stress effects of C-1 subluxations on the human body, making possible thereby   statistical   analyses  between  C-1  misalignments (determined by X-ray analysis)  and such postural distortion-stress effects on the skeletal framework as directly result from the misalignment interferences of C-1 on the nervous system and its  normal  functioning.   This machine  can demonstrate the postural distortion-stress effects of C-1 subluxation on the spine by checking the malpositional  relationships of upper thoracic vertebral segments and pelbis prior to and subsequent to C-1 correction, indicating thereby the corrections obtainable throughout the spine and thus reducing the need for repeated applications of X-radiation to the patient.   The machine has movable elements which provide indications of corrections or displacement and has a pair of weight sensitive platforms with horizontally adjustable pads (foot guides).  The platforms are coupled to force transducers which indicate a means for measuring the portion of total body weight that is supported by each of the patient's feet.   The pads are individually or simultaneously adjustable toward and away from each other to properly spaced the feet relative to the ilii.

Title: Method and apparatus for evaluating color image signals
Inventor: AOKI HIROYUKI
IPC: G06T7/40
Filed: 1990-11-27
Abstract: ABSTRACT OF THE DISCLOSURE      In a color image signal evaluating apparatus and method, a color image signal corresponding to each pixel position on a display screen is converted by a color signal converter to an I signal and a Q signal, which are stored, as pixel data, in first and second image memories, each at an address corresponding to the pixel position.  The I signal and Q signal read out of the first and second image memories are differentiated by first and second differentiators, respectively, with respect to the directions of pixel arrays to thereby obtain an I-signal differentiated value and a Q-signal differentiated value at each pixel position.  A vector-composed value of the I-signal differentiated value and the Q-signal differentiated value at each pixel position is calculated and is stored in a third image memory.  An evaluation part represents, as a factor of the degree of a color reproduction error, the magnitude of a change in the differentiated vector-composed value stored in the third image memory and compares the factor with a fixed value, thereby determining whether or not the color reproduction error is within a given limit range.

Title: Modular procedure used with a engineered dna implant for physical mapping/overlapping chromosomes with ready for gene isolation/ ready for sequencing contigs
Inventor: PREDDIE RICK E
IPC: C07H21/04
Filed: 1990-11-27
Abstract: Abstract:          In overlapping chromosome fragments to physical map chromosomes it is  most  desirable  to  have  a  single  method  which combines, simplicity, precision, speed and reproducibility,and produces long contiguous stretches of ordered DNA. Until now there was no method available that meets these criteria. In this invention a,  "3rd generation mapping method",  which uses a strategy based on a modular contig building procedure and a  "vector-cloning site-implant", all the above desirable criteria are met. In this method unique "fragment ends" copied by the polymerase chain reaction (PCR) using two pairs of primers, from uniformily sized fragments produced by complete digestion of chromosomes with selected 6-base blunt cutting restriction enzymes, are used to completely overlap and orientate vectors carrying chromosome fragments. The method is applicable to all types of vectors and all sizes of fragments. Vectors carrying implants are called RSCC vectors. Overlapping is fast,   precise,   efficient   (little  or  no  redundancy)   and reproducible. In addition, the ends used to overlap fragments in one  library  are  portable  to  any  other  library  of  the  same chromosome, where they can be used to group clones in the library into "contigs members" before they are mapped.
