Patent CA-2078385-A1 (CA)
Inventor: NITZ LARRY THEODORE
IPC: F16H61/02
Filed: 1992-09-16
Abstract: An improved torque converter clutch (TCC) engagement control method utilizing a combination of pressure control and flow control methodologies to ensure consistently smooth and timely TCC engagement. The engagement is initiated with a pressure control methodology in which the duty cycle of a PWM actuator is selected to produce a desired pressure differential across the TCC clutch plate.  However, if the flow conditions are such that the pressure control methodology fails to promptly initiate engagement of the TCC, as detected in relation to the speed difference across the torque converter, a flow control methodology is substituted for the pressure control to initiate clutch engagement.  In this case, the duty cycle of the actuator is adjusted to a value which provides full or near-full fluid flow.  This control is maintained for a predetermined period, or until the speed difference across the torque converter indicates initiation of TCC engagement.  At such point, the pressure control methodology is resumed to complete the TCC engagement.

Patent CA-2092815-A1 (CA)
Title: Process for purifying magnesium
Inventor: MIKUCKI BARRY A
IPC: C22B26/22
Filed: 1992-07-24
Abstract: Hydrogen is essentially removed from molten magnesium by the use of a degassing step, thereby substantially avoiding the formation of zirconium hydride when zirconium and silicon are added to the molten magnesium, after the degassing, in order to precipitate iron contamination in the magnesium as an intermetallic compound comprising Fe, Zr and Si; the ratio of the three metals in the intermetallic compound can vary over a wide range. By essentially avoiding the formation of slow-settling insoluble ZrH2, the iron removal is more efficient and the settling of the insolubles is expedited. Also, the Fe and Si are more effectively and consistently precipitated.
Patent CA-2094549-A1 (CA)
Title: Segregation method of dynamic channel allocation in a mobile radio system
Inventor: ERIKSSON HAKAN O
IPC: H04B7/005
Filed: 1993-04-21
Abstract: ABSTRACT    A method for adaptively allocating channels for connections between base station and mobiles is disclosed.  The channels accessible to the base stations for establishing connections with mobiles are ranked in at least one priority list based on transmission loss intervals.  Each channel is ranked in the priority list according to their success at previous connections.  The amount of power required for a channel allocated from a list associated with a low transmission loss can be set lower thereby reducing the interference associated with the channel and increasing system capacity.  A self planned system evolves where channels are allocated for connections based on their past connection history.          Thus, the selection of channels which may interfere with calls in neighboring cells or which may suffer substantial interference from a neighboring base is avoided.

Title: Viscometer for measuring a single sample successively at a plurality of temperatures
Inventor: FORBES DAVID W
IPC: G01N11/04
Filed: 1993-10-07
Abstract: ABSTRACT OF THE DISCLOSURE      A viscometer is described for measuring a single sample successively at a plurality of temperatures.   At least two tubular bodies are vertically spaced, such that a single sample of liquid flows by force of gravity between the tubular bodies. Each of the tubular bodies has a first end, a second end, and a flow channel extending between the first end and the second end.  A heating coil is provided for heating liquid passing through the flow channel. A temperature sensor is provided for sensing a temperature of liquid passing through the flow channel.  Two meniscus sensors are provided.  A time sequence initiating meniscus sensor senses the passage of a meniscus of liquid within the flow channel.  A time sequence terminating meniscus sensor is spaced a known axial distance along the flow channel from the first meniscus sensor, and senses the passage of the meniscus of liquid within the flow channel.  The heating coils  of  the  two  tubular  bodies  are  set  for  different temperatures.  A back pressure relief vent is provided between the tubular bodies thereby preventing back pressure  from adversely affecting the flow of liquid by force of gravity between the tubular bodies. A computer controller is connected to the meniscus sensors of each of the tubular bodies and a timer. As liquid flows successively through the tubular bodies the computer activates the timer when a first signal  is received from the time initiating meniscus sensor indicating the passage of a meniscus of liquid.  The computer stops the timer  when  a  second  signal  is  received  from  the  time terminating meniscus sensor indicating the passage of the meniscus of liquid.   The computer performs calculations of viscosity based upon the timed duration of flow over the known distance between the first signal and the second signal.  The computer   receives   signals   and   performs   calculations successively as the single sample of liquid successively passes through the tubular bodies.

Title: Nitroglycerine plaster and process for making it
Inventor: KLEIN ROBERT PETER
IPC: A61P9/10
Filed: 1992-05-25
Abstract: The invention relates to a dermal plaster for the transdermal provision of nitroglycerine consisting of a carrier film and a removable protective film and a special adhesive mass containing nitroglycerine on the basis of a cross-linked acrylatevinyl acetate copolymer in which the monomer mix used for polymerisation contains 21 to 40% wt. vinyl acetate, 55 to 70% wt. of an acrylic acid-C2-8-alkyl ester and 3 to 10% wt. of an acrylic acid-C2-4-hydroxyalkyl ester and which is cross-linked by heating and the removal of any solvents present after the addition of a customary cross-linking agent and the nitroglycerine.  The special adhesive mass of the invention has not only a high absorption capacity but also a high and controllable capacity for giving off nitroglycerine so that the delivery area of the plaster can be kept small for the necessary quantity to be delivered daily and hence the cost of the plaster is very low.  At the same time, the manufacturing process is simplified by the simple adhesive compound, there is not need for the addition of further substances to improve the transepidermal conveyance of substances and the cost of the plaster can thus be kept down and the risk of skin irritation is avoided.
