Patent CA-2151447-A1 (CA)
Title: Security paper
Inventor: HARRIS COLIN AUSTIN
IPC: D21H27/02
Filed: 1995-06-09
Abstract: Security paper carries an intricate tactile surface profile pattern which has been imparted to the paper during its manufacture,  at  a  stage  after  initial de-watering but before final drying, by passing the paper through a nip between a forming surface corresponding to the desired pattern and a backing surface.   The tactile pattern is of excellent durability,  and  its  intricacy offers  a high degree of security.   The tactile pattern is visible when viewed   under   low   angle   light,   which   facilitates verification or authentication of security documents made using the patterned paper.
Patent CA-2151772-A1 (CA)
Title: Method and Apparatus for Throttle Valve Control of a Calender Roll Actuator
Inventor: REED GORDON KENNETH
IPC: D21G1/02
Filed: 1995-06-14
Abstract: A throttle valve is provided in each actuator of a calender roll controller with the throttle valve controlling an internal air orifice within each actuator to provide a substantially uniform air mass flow of either hot or cold air.  Each throttle valve is controlled in response to the temperature of the air being delivered by the actuator such that a smaller orifice is provided for hot air than for cold air to provide substantially uniform air mass flow from each of the actuators and therefore substantially uniform air velocity to better control the temperatures of the longitudinal zones of a calender roll and better maintain boundaries between the zones.  In addition to throttle valve control of the actuators, an air scoop concentric with a calender roll being controlled and spaced from the calender roll is provided to channel air from the actuators over the calender roll.  The scoop comprises heat insulating material to prevent heat loss out the back of the scoop.  In addition, a plurality of arcuate zone strips are provided on the concave inner surface of the scoop and in substantial alignment with the plurality of actuators for channeling air from the actuators. The arcuate zone strips are spaced apart from one another for thermal separation such that thermal diffusion among longitudinal zones of a calender roll within the scoop are substantially eliminated.

Inventor: SARTHY APARNA V
IPC: C12N9/04
Filed: 1993-12-22
Abstract: An isolated DNA segment is disclosed which is derived from a Saccharomyces cerevisiae sorbitol dehydrogenase gene and which functions to increase expression of an associated foreign polypeptide when the DNA segment and the gene coding for the foreign polypeptide are operably linked in a vector in such a manner that the vector is replicated and carried by a host yeast cell. The functionally active portion of the segment is under the control: (i) a transcriptional regulatory sequence of the sorbitol dehydrogenase of Saccharomyces cerevisiae, (ii) a translation initiation regulatory sequence of the sorbitol dehydrogenase gene of Saccharomyces cerevisiae, and (iii) a termination regulatory sequence of the sorbitol dehydrogenase gene of Saccharomyces cerevisiae. Yeast cells containing these regulatory sequences linked to a foreign DNA sequence are grown in medium containing sorbitol under conditions permitting a foreign polypeptide to be expressed.

Title: Downhole depth correlation and computation apparatus and methods for combining multiple borehole measurements
Inventor: MEYER WALLACE HAROLD JR
IPC: G01V11/00
Filed: 1995-10-19
Abstract: The current invention is directed toward the use of a downhole computer and downhole storage within a measurement-while-drilling (MWD) downhole subassembly to process data from the response of a plurality of sensors of different classes or one or more sensors of the same class which exhibit different measure points and vertical resolutions. Classes or types of sensors applicable to the invention include, but are not limited to, electromagnetic, acoustic, and nuclear. Sensor measurements are made essentially simultaneously. In combining downhole responses from one or more sensors to obtain parameters of interest, a critical prerequisite is downhole depth correlation and vertical resolution matching of all sensor responses prior to combination. Methods and apparatus are disclosed for performing these critical functions within the limits of telemetry and downhole storage capacities of current MWD systems, Alternate embodiments of the invention include wireline operations in which telemetry band width is limited by components such as single conductor logging cables employed in logging wells under high pressure.

Title: A method of metering a flowable lubricant of a chain drive
Inventor: GRAF WALTER
IPC: F16N29/02
Filed: 1996-02-06
Abstract: The chain to be lubricated has at least one chain wheel. The method for lubricating the chain uses an appts. for dispensing in pulses a lubricating fluid. This appts. includes a pulse dispensing system with a control device. The lubricating fluid is dispensed in the rotating direction of the chain wheel in front of it, and/or in the area where the chain is wound on the wheel. The number of rotations of the chain drive per second is measured and fed to a computer. This acts on the control unit for the pulse dispensing system. The computer releases the dispensing system at a predetermined number of rotations. The computer blocks the system when a value Fz calculated by the computer from the number of rotations of the chain wheel per second exceeds an upper threshold. The number of rotations per second is programmable and the threshold is selected such that the chain wheel operates without spin with respect to the dispensed lubricant.

IPC: A61M5/31
Filed: 1996-05-01
Abstract: The present invention provides in part an improved drug injection system, comprising novel self-aspirating syringes, drug cartridge and and novel needle assemblies. It is primarily intended for administering of local anesthetic by dentists, but it can be used equally well in medical and veterinary applications. In one aspect, the novel syringe is made lightweight, comfortable to hold and corrosion resistant. In another aspect, some novel changes in the design of the syringe reduce the possibility of transmitting an infection from the blood of one patient into the blood of another. Additionally, innovation in the design of needle assembly makes the syringe safe to use even without prior sterilization and at the same time eliminating the possibility of transmitting infection as the result of human error.
