Patent CA-2170183-A1 (CA)
Inventor: BARR JOHN D
IPC: E21B47/18
Filed: 1996-02-23
Abstract: A system for controlling the rotation of a roll stabilisable control unit in a steerable rotary drilling assembly comprises an instrument carrier rotatably mounted on a support connected to the drill string. A first rotatable impeller is mounted for rotation by a flow of drilling fluid over the impeller and is coupled to the instrument carrier so as to transmit a torque to it. Sensors carried by the instrument carrier sense the rotational orientation of the instrument carrier and produce a control signal indicative of its rotational orientation, and the torque applied to the instrument carrier by the impeller is controlled, at least partly in response to said signal, so that the instrument carrier can, for example, be roll stabilised if required. A second rotatable impeller is coupled to the instrument carrier for transmitting to it a second torque, which may also be controlled, in the opposite direction to the torque transmitted by the first impeller The provision of two opposed impellers allows the rotation of the control unit to be controlled over a greater range than is possible with a single impeller.

Title: Human limb load sensing device
Inventor: STASIUK TWAIN
IPC: A61B5/22
Filed: 1996-09-06
Abstract: An apparatus is used for sensing the amount of weight applied to the limb of a patient. The apparatus includes a sensor for attachment under the foot, a control unit for receiving and processing an output signal from the sensor, and an audio output for producing feedback signals to user. The apparatus generates audio feedback to the patient indicating the amount of load being applied to the limb. The audio feedback volume and frequency decrease as load increases and is attenuated to zero when the load on the sensor reaches a selectable threshold load. The apparatus also provides an audio overload alarm signal when a load exceeding the sum of the threshold load value and a selectable overload value is being applied to the limb. The apparatus is automatically calibrated to the maximum load that can be applied to the sensor, thus eliminating the need for manual calibration. The threshold load value, the overload alarm value, and the audio output volume are selectively adjustable.

Patent CA-2189264-A1 (CA)
Inventor: WEISSER FRANK J JR
IPC: H04M3/00
Filed: 1995-03-21
Abstract: A method of mediation of traffic across a particular interface between the Advanced Intelligent Network operated by a local exchange carrier and an outside service provider is disclosed. The particular interface is defined between an application by a non-local exchange carrier service provider for some form of enhanced telephone service requiring use of the Advanced Intelligent Network and a shared execution environment interpreter on the other side of the interface. Mediation is conducted by the shared execution interpreter that is run on a local exchange carrier operated service control point. The shared execution interpreter enforces sufficient rules so that the local exchange carrier does not require knowledge of the details of implementation of the service provider's application. The methodology defines a unique transaction identifier that is defined and known on the local exchange carrier side of the interface. A table is created carrying the unique transaction identifiers with service process identifiers generated by various service provider applications. In this way, the shared execution environment interpreter can pass messages and instructions across the interface to the service provider's application that only reference the application's internally generated service process identifier. This isolates the service provider application from unnecessary information about the operation of the network and the operation of other service providers services. Mediation rules include testing of tables to determine whether a directory number referenced in a message request from a service provider application is a customer of the service provider, whether trunk group routing requests are valid for the service providers and whether any access to, or particular levels of access to, certain network elements are authorised for the service provider requesting same.

Title: Hydrogenation of substrate and products manufactured according to the process
Inventor: HARROED MAGNUS
IPC: C11C3/12
Filed: 1995-07-03
Abstract: A typical traditional reactor for hydrogenation consists of a tank filled with a liquid and a gas and a small particle catalyst. The reaction is carried out at high pressures and high temperatures. Lack of gas on the catalyst surface limits the velocity of reaction. Much work has been done to increase the quantity of gas on the catalyst. It has not been possible to solve this problem effectively with the techniques of today. According to the invention an extra solvent is added to the reaction mixture. By bringing the whole mixture (solvent, substrate; hydrogen and reaction products) to super-critical or near-critical state, a substantially homogeneous mixture can be obtained. By this method it is possible to control the concentration of gas on the catalyst to the desired level. The velocity of reaction is thereby increased considerably. The hydrogenation reactions principally involved comprise hydrogenation of carbon-carbon double bonds (C = C) in lipids; hydrogenation of COOR to C-OH and HO-R to produce fatty alcohols; and direct hydrogenation of oxygen to hydrogen peroxide.
