Abstract: A recording medium cassette comprises a cassette case cassette case board and a release part. The cassette case board has a plurality of board terminals and also has positioning holes formed in its outer surface so as to expose the plurality of board terminals along with insertion guide channels formed consecutively at the lower ends of the positioning holes so as to reach the lower end of the cassette case. Also, a release part slopes towards the lower end of the insertion guide channel away from the outer surface. The angle of the release part with respect to the height of the cassette case is greater than the angle of an inclined portion, which spans from contact points to free end parts of resilient connector contacts set up at a recording/playback apparatus connector, with respect to the height of the cassette case, and the connector contacts do not come into contact with the release part when the recording medium cassette is installed in the recording/playback apparatus and the contacts are therefore brought together in a reliable manner.

Patent CA-2135305-C (CA)

IPC: C12G3/08
Filed: 1993-05-04
Granted: 2001-07-24
Abstract: Method and apparatus for the treatment of fluids, particularly wine, to remove unwanted substances. The wine is first treated in a reverse osmosis treatment unit, generating a retentate and a raw permeate. The membrane for the reverse osmosis unit is selected to pass in the permeate the unwanted substances, which in the case of wine may be volatile acidity (ethyl acetate and acetic acid). The raw permeate is then subjected to a treatment: column. In the case of volatile acidity, this is an anion exchange column, which removes the acetic acid from the permeate by anion exchange and removes the ethyl acetate by base hydrolysis. This produces a purified permeate, which is depleted in volatile acidity (which is passed through with the raw permeate), but contains other components desirable for the wine. The purified permeate is then recombined with the retentate from the reverse osmosis column, and the result is wine with the volatile acidity and little else removed. This wine may be recirculated through the system to remove yet more of the volatile acidity. The method may also be applied to the removal of acetaldehyde, in which case a distillation column is used instead of the anion exchange column, and the distillation residue constitutes the purified permeate which is recombined with the retentate from the reverse osmosis column. An embodiment utilizing a high-energy distillation column may be used to separate out alcohol and water, and then add either the alcohol or the water back to the reverse osmosis retentate, thus producing either a higher alcohol or a lower alcohol beverage, respectively.

Abstract: A multipoint data collection system uses multiple parallel data buses (A, B, and C) connecting a central controller (10) to addressable sensor interfaces to permit any sensor (14, 15, or 16) to be connected to a central controller (10) over any one of the data buses. Faults on a data bus (A, B or C) may be bypassed, or multiple sensors (14, 15, and 16) monitored simultaneously in real time, through the use of the parallel data buses (A, B and C). Digital address signals and analog data are transmitted on the same data bus, distinguished from one another by restricting the voltage range of the analog data to voltages above the voltage corresponding to a digital zero and below the voltage corresponding to a digital one.

Title: Load measuring device with a load cell and method for introducing a load into the load cell
Inventor: HOPKINS RANDALL K
IPC: G01G5/00
Filed: 1997-03-10
Granted: 2006-08-01
Abstract: A load to be measured is transmitted to a load cell, such as a compression load cell, through a double piston, single cylinder load transmitter that has a pressure chamber between two pistons in the single cylinder. One piston bears against the load. The other piston bears against the load cell to form a floating link between the load and the load cell when a sufficient pressure is introduced into said pressure chamber to prevent unwanted, off--center load application force components from adversely affecting any measured results. Preferably, at least one axially outwardly facing end surface of the piston bearing against the load cell has a curved end surface area. A rocker pin with a pressure controllable variable length may be formed by making both axially outwardly facing end surfaces curved. Several load transmitters may be arranged in parallel to transmit larger loads into a load cell.

Abstract: A viscous heater for heating cooling water for cooling a water cooled engine is disposed in a cooling water circuit, and a front heater core is disposed in the cooling water circuit at a downstream side of the viscous heater with reference to a flow direction of the cooling water.  Only when a heating operation is the maximum heating operation or the maximum heating operation is desired, a viscous clutch is turned on to transmit a driving force of the engine to the viscous heater.  When the maximum heating operation is not desired, the viscous clutch is turned off so that the driving force of the engine is not transmitted to the viscous heater.          Therefore, a load of the engine is reduced, and the cost for running the vehicle can be lowered.
