Title: Warning system distinguishing wheel skidding and wheel slipping
Inventor: MAY KENNETH A
IPC: B60R16/02
Filed: 1992-12-07
Abstract: A warning system alerts a driver of a motor vehicle to different types of traction losses. A first sensing circuit (10) detects a loss of wheel adhesion by monitoring a vehicle drive line for a pronounced vibration within a range of between ten and fifteen Hertz. A second sensing circuit (12) monitors a brake light circuit to detect application of a vehicle brake. A logic circuit (28) combines outputs (A and B) from the first and second sensing circuits and outputs command signals (C and D) that distinguish between a loss of wheel adhesion due to wheel skidding and a loss of wheel adhesion due to wheel slipping. A warning device includes two indicators (36 and 38) that receive the respective command signals and produce sensorially distinguishable warning signals for eliciting different responses from the driver.

Patent CA-2129459-A1 (CA)
Inventor: DAS PRALAY K
IPC: E21B47/00
Filed: 1994-08-04
Abstract: A load cell for sensing weight and torque on a drill bit during a drilling operation includes a cylindrical load cell made from a material with minimum residual stress. A plurality of strain gages are arranged symmetrically on each load cell and electrically coupled to form two Wheatstone bridges. The load cells are mounted 180 degrees apart in radial pockets drilled in a drill collar wall. A half Wheatstone bridge from one load cell is electrically coupled with a half Wheatstone bridge from the other load cell to form a Wheatstone bridge for measuring WOB and a similar coupling is made to form another Wheatstone bridge for measuring TOB. Tn another embodiment, additional strain gages in another Wheatstone bridge measure differential pressure. The output of the pressure and weight bridges are electrically combined to provide a weight signal unaffected by differential pressure fluctuations. The load cells are force fit in the radial pockets in the drill collar and a cap is installed on each pocket housing a load cell to protect the load cell from drilling fluid.      The strain gages in each load cell are placed to minimize the effects of bending, hydrostatic pressure, temperature, differential pressure and cross talk between WOB and TOB measurements. The load cells can be replaced easily and drill collar gauging is not required. Since the strain gages are not directly attached to the drill collar, the high residual stress in the drill collar does not cause the strain gages to drift.

Title: Recombinant dna and transformant containing the same
Inventor: MORI TETSUYA
IPC: C07K14/505
Filed: 1994-12-01
Abstract: Insertion of IFN-alpha promoters in recombinant DNAs improves their expression efficiencies for useful polypeptides. Expression of such a recombinant DNA in host cells of mammalian origin is artificially controllable by the presence and absence of  external  stimuli using  IFN-alpha  inducers.   Thus  trans-formants with  such a recombiant  DNA readily  increase  to  a miximized cell density with causing neither damages nor extinc-tion due to polypeptides they produce, and subsequent exposure to IFN-alpha inducers allows the proliferated cells to effi-ciently produce polypeptids with significant glycosylations.
Patent CA-2138685-A1 (CA)
Title: Shade Operator
Inventor: NIJS FREDERIK G J
IPC: E06B9/78
Filed: 1994-12-21
Abstract: An operator for a window or like shade serves to turn a shade roller to a new desired position as the result of a torque applied from a manually operable source, such as a chain operated wheel.  The device includes a helical spring that is seated within a fixed bushing with its outer surface in contact with an inner cylindrical surface of the bushing. When torque is applied from the manually operable source, one overlapping end of the spring is moved away its other end to reduce the spring diameter and hence release any frictional engagement of the spring with the bushing, thus allowing the torque to rotate the spring, which rotation is transmitted to the roller.  However, when no such manually applied torque is present, the spring and the roller remain effectively locked in position.  Any torque applied from the roller due to the weight of a partly lowered shade acts to tend to increase the spring diameter and thus to ensure a binding frictional engagement between the bushing and the spring.

Title: Bypass switching and messaging mechanism for providing intermix data transfer for a fiber optic switch
Inventor: BENNETT DWAYNE R
IPC: H04B10/27
Filed: 1995-07-26
Abstract: A system and method for inserting intermix frames into a continuous stream of class 1 frames.  A bypass bus, in conjunction with a first-in-first-out (FIFO) buffer, are provided within a fiber optic switch element, to route intermix data frame through the switch that is concurrently transmitting class 1 data.  Achannel module, which is disposed between a switch module and a plurality of fiber optic channels, comprises a port intelligence system and a memory interface system. The port intelligence system is responsible for transmitting and receiving data from the fiber optic channels in accordance with a predetermined protocol, preferably Fibre Channel.  The memory interface system comprises a receive memory unit, a transmit memory unit and memory control logic.  When an intermix frame is to be passed through the switch, the intermix frame is passed to a FIFO concurrently while class 1 data transfer occurs via the bypass bus.  After the intermix frame has been completely written into the FIFO, the memory control logic waits to detect a tagindicative of a break in the class 1 data transfer.  The control logic will then switch the MUX and cause the FIFO to commence writing the intermix frame to the port intelligence system for transfer to a predetermined fiber optic channel.
