Patent CA-2018637-A1 (CA)
Title: Countercurrent separation process and apparatus
Inventor: SHINNAR REUEL
IPC: B01D11/04
Filed: 1990-06-08
Abstract: Abstract of the Disclosure A multistage countercurrent separation apparatus and method is described.  Each stage includes a mixer zone and a settler zone, both of which have temperature control means to achieve a first temperature and a second temperature, respectively, in the mixer and settler zones.  Solvents used in the process are selected so that they have at least one immiscibility transition temperature such that they form a single homogeneous phase at said first temperature and two heterogeneous phases at said second temperature. By carrying out the process, a solute or solutes introduced into the system may appropriately be efficiently concentrated or separated with minimal agitation.  Furthermore, because emulsification by rapid agitation is avoided, the homogeneous phase quickly coalesces upon passing into the heterogeneous phase, thereby increasing the throughput which may be achieved by the extraction process.

Title: Movement detection system
Inventor: BILSBOROUGH ROY
IPC: G21C17/003
Filed: 1990-06-29
Abstract: ABSTRACT OF THE DISCLOSURE              In order to detect abnormal movement of a body, such as a boiler unit in a nuclear reactor a fluid is fed into a passage, and movement of the body causes variation in the resistance of the passage to flow of the fluid.   This variation is detected by measuring a change in flow rate or a change in fluid pressure.   The detector preferably comprises a sleeve valve comprising a pipe section which is attached to a central one of three adjacent boiler units and a sleeve which is normally positioned over a port in the pipe section and which is coupled to both of the outer boiler units, so that abnormal movement of any of the three units causes opening of the port.   The coupling comprises an arrangement of levers and linkages which compensates for normal movements of the boiler units caused by temperature rise.

Title: Spring-applied, hydraulically released brake actuator having positive clearance slack adjuster mechanism
Inventor: TA CUONG M
IPC: F16D65/56
Filed: 1991-07-26
Abstract: A spring-applied, hydraulic pressure released brake actuator having a modular slack adjuster assembly in which a friction ring is arranged to limit axial movement of a nut member to which a brake shoe is connected, thereby establishing a predetermined brake shoe clearance with a vehicle wheel or brake disc. A spindle that is threadedly engaged with the nut member is connected to the actuator piston by means of a cone clutch that is disengaged during a brake release in the event the return stroke of the piston exceeds the predetermined brake shoe clearance due to brake shoe wear during the preceding brake application.      This disengagement of the clutch causes the spindle to be rotated relative to the nut member under the influence of a slack adjuster spring in order to compensate the piston overtravel.
