Patent CA-2008777-A1 (CA)
IPC: B60T8/58
Filed: 1990-01-29
Abstract: ABS VARIANT NOMINAL HOLD PRESSURE          Abstract of the Disclosure A brake control system is described that maximizes the braking efficiency of an under-damped actuator, such as a motor-driven linear screw.  When an incipient lock condition is detected, the system determines the optimal brake pressure, relieves brake pressure and measures the duration of the pressure release.  When the wheel is approaching recovery, but has not yet substantially recovered, the system holds brake pressure constant at a value calculated to represent the amount of pressure remaining at the wheel brake.  This calculated hold value is based upon the measured optimal pressure and the measured release duration, and allows the wheel to continue to reaccelerate towards recovery while preventing unnecessary pressure relief.  Once the wheel recovers, the system reapplies brake pressure to a substantial fraction of the optimal pressure without over-exciting the actuator and over-shooting the desired pressure.

Title: Facial moisturizing mask
Inventor: BLEWITT RUTH
IPC: A42B1/06
Filed: 1990-02-12
Abstract: ABSTRACT OF THE DISCLOSURE        The present invention provides a facial moisturizing mask comprising a face cover and a head strap for securing the cover in position on one's face.  The cover includes an inner layer to be placed directly over one's face and a backing for the inner layer.  The inner layer has a soft liquid absorbent construction and the backing is liquid impervious to prevent moisturizer applied to and absorbed by the inner layer from escaping outwardly thereby trapping the moisturizer to enhance its action on one's face.

Title: Sealing collar for a resuscitator or respirator
Inventor: LINDLEY JOHN E
IPC: A61H31/02
Filed: 1990-03-14
Abstract: ABSTRACT OF THE DISCLOSURE      A collar for a respirator or resuscitator that provides for a relatively air-tight seal on the neck of the patient but is gentle enough to prevent injury to the skin and subcutaneous  tissue as well as being constructed so as to minimize pressure on the anterior neck  and  anterior  lateral  neck  to  avoid  undue injurious  pressure  on  the  jugular  vein,  carotid arteries, trachea and other delicate structures in this area of the neck.  The collar is of soft foam, closed cell elastic sheet material that has the usual central neck opening therein and a radial slit having overlappable edges.  The lower portion of the collar is located on the head side of the lower part of the two-part collar frame or wall which separates the head and body sides of the machine and which parts have opposed recesses to define an opening to  loosely receive the neck of a patient.   With the two frame parts separated and a patient in place with the neck in the collar opening,  the  collar  is brought up tightly around the back of the neck and the lower collar portion clamped against the head side of the lower frame part by a U-shaped clamp.   The upper portion of the collar then is passed between the two separated parts of the collar frame to the body side thereof.  The wall or frame parts are then closed and the flaps on the body side of the frame defined by the slit in the foam-like sheet or collar are folded and overlapped over the patient's upper torso adjacent the neck.      The body side of the upper frame part movably carries an anterior chest seal block which is moved down on the foam-like collar material, pushing the anterior point of pressure of the collar away from the anterior neck and anterior lateral neck of the patient and onto the bony structure of the anterior chest and anterior-lateral chest, namely the sternum (breast bone) and both clavicles (collar bone). That portion of the foam-like sheet extending on the body side then is folded and pushed up against the anterior chest seal block and the upper wall part and is clamped thereagainst by the two arms of a scissors clamp.

Title: Process for preparing alcoholic beverages including heating step for reducing diacetyl content
Inventor: MURAYAMA HIROSHI
IPC: C12C11/00
Filed: 1990-05-15
Abstract: (57) Abstract A method of producing sake, involving the step of hesting fermented liquor, which comprises adjusting the dissolved oxy-gen concentration or a prefermented liquor to less than 1 mg/l and heating the liquor at a given temperature within the range or 40 to 120°C for a time predetermined according to the required target value of the quantity of residual diacetyl precursor. This procedure serves to not only convert most of the diacetyl precursor contained in the prefermented liquor into diacetyl which can easily be decomposed by yeast, but also reduce the quantity of the diacetyl itself. As a result, it now becomes possible to dispense with a prolonged low-temperature post-fermentation which has hitherto been necessary for reducing the diacetyl content and to greatly shorten the time necessary for producing sake.

Title: Dynamic optimization of a single relation access
Inventor: ANTOSHENKOV GENNADY
IPC: G06F17/30
Filed: 1990-12-28
Abstract: Abstract of the Disclosure Dynamic optimization of a database access.  During execution, based on the actual number of retrieved keys, or on the actual number of fetches (I/O operations) used to retrieve keys, a decision is made between alternative paths for completing the access.  The invention features deciding not to retrieve records using the keys retrieved using a particular index if that retrieval could be expected to take longer than retrieving all records.  A second index scan is begun during the first index scan, and a decision between alternative paths is made based on the number of keys retrieved during the second scan, or on the number of fetches incurred in the second scan.  Scanning of an index is terminated if the number of retrieved keys exceeds a threshold corresponding to the point at which record retrieval using keys is likely to be more costly than full record retrieval.  If all index scans are terminated, a full, sequential retrieval of all records is done.
