Patent CA-2194960-A1 (CA)
Inventor: SCANLON KEVIN J
IPC: A61K38/00
Filed: 1995-07-12
Abstract: The steroid enzyme 5.alpha.-reductase is responsible for the conversion of testosterone to the more-potent androgen dihydrotestosterone (DHT). The catalytic cleavage of nucleic acid encoding 5.alpha.-reductase by a ribozyme which selectively recognizes such nucleic acid reduces the level of expression of 5.alpha.-reductase by mammalian cells including human cells treated with such ribozyme. The reduction of nucleic acid (e.g. mRNA) levels leads to a corresponding reduction of enzyme levels and dihydrotestosterone levels in surrounding tissues, thus providing a therapeutic effect. The transformation of 5.alpha.-reductase producing cells with an expression vector containing a structural gene for a ribozyme is shown to decrease 5.alpha.-reductase expression. Pharmaceutical compositions and methods useful for topically administering effective amounts of such a ribozyme to hair follicle cells also are exemplified.

Inventor: GIRARD ALFRED L
IPC: B31B50/62
Filed: 1997-04-08
Abstract: A method and apparatus for detecting the presence or absence of white glue on a white background of a box blank being processed on a box blank folding machine using a laser scanner.   The laser scanner directs a continuous beam of light at approximately a 20 degree angle of incidence from the horizontal to a white glue bead, and reflection of the light beam from the glue bead is detected by a receiver.          The receiver generates a signal which is processed by a pulse processor.   If no glue is present on the white surface, then there is no reflected light detected.   The same method and apparatus is also used to detect embossing on box blanks.

Title: X-ray bone densitometry using a vertically scanning gantry
Inventor: STEIN JAY A
IPC: A61B6/00
Filed: 1997-05-15
Abstract: The present invention provides a system that reduces the complexity of existing dual energy x-ray equipment which typically requires more complicated mechanisms to measure bone density, to a system with a single axis of mechanical motion and with a patient providing repositioning motions. This configuration allows for a much more compact design and smaller equipment "footprint," thus taking up less floor space in examination rooms and allowing for multiple uses of one room. The system of the present invention eliminates the need for a patient support table which can affect x-ray transmission because of the thickness and construction of the table which are dictated by the weight of the patient. The system includes a main cabinet or gantry enclosure which contains an x-ray source and ancillary support electronics and mechanisms. An extension arm positions a detector assembly on a side of the patient opposite to the source assembly and fixes the distance between the source and detector assemblies. The source and detector assemblies are capable of making dual energy bone measurements. The source assembly, detector assembly and extension arm form a gantry and the source assembly and detector assembly are confined to move in unison in a vertical scanning motion. A drive mechanism in conjunction with a precision guide rail provides a stable, smooth vertical scanning motion of the gantry. A counter balance system is provided to reduce the forces required to move the gantry. In addition, the extension arm may either fold or retract into the main cabinet to reduce the system volume when not in use.

Patent CA-2218321-A1 (CA)
Inventor: GU YONGHAI
IPC: H04L7/04
Filed: 1997-10-10
Abstract: The timing of an access burst received in a base station of a wireless communications system is determined by detecting one or more zero bit fields, constituting predetermined sequences of identical consecutive symbols in the access burst. For each possible timing of the access burst, whether a predetermined sequence is present in the respective position in the access burst is detected by predicting a sample of the received signal in the current symbol period from a sample of the received signal in the preceding symbol period assuming identity of symbols in the current and preceding symbol periods, producing a squared distance between predicted and received samples for the current symbol period, producing a threshold in dependence upon a power of the received signal for the preceding symbol period to accommodate fading, and comparing the squared distance with the threshold, continuing for successive current symbol periods until the end of the sequence or until the respective threshold is exceeded. The squared distances are accumulated for each possible timing, the least accumulated squared distance determining which of the possible timings for which the predetermined sequences are detected, if there is more than one, is the access burst timing.

Title: Elevator stopping device
Inventor: KOSHAK JOHN W
IPC: B66B5/18
Filed: 1996-10-04
Abstract: A safety brake device (1) for hydraulic elevators acts by arresting the axial movement of the elevator ram (3) with respect to the main hydraulic cylinder (5) of the elevator. The safety brake (1) utilizes two lever acting brake arms (27) lined with an accretable metal (31), for example annealed copper, as the friction material. When actuated, the brake arms (27) contact the ram (3) circumferentially to slow and stop the falling ram. The lining material (31) is machined inside the brake arms (27) to a diameter slightly less than the diameter of the ram (3), and when actuated, the accretable material (31) on the brake arms (27) contacts the ram (3) with sufficient frictional force to stop the downward motion of the ram (3).      The safety brake (1) may be actuated by loss of hydraulic pressure, by an electronic signal from a hydraulic pressure detector, by down overspeed or by an uncontrolled down motion detector. In the case of the hydraulic pressure loss, reapplication of normal pressure in the hydraulic cylinder (5) will automatically reset the brake (1). The safety brake device (1) can also be configured for use as a safety brake on other hydraulic or pneumatic cylinders or for use as a safety brake on cable-actuated traction elevators.
