Patent GB-2043799-A (GB)
Title: Draining oil from bearing
IPC: F16N7/40
Filed: 1979-03-05
Abstract: A bearing chamber is provided with drains on both sides of the bearing thus preventing oil surges spilling oil over the chamber seals. The bearing chamber has three compartments and the chamber is pressurized by air passing through the seals at its ends. A main drainage duct drains the main bearing compartment via a scavenge pump to the oil tank. Passages through the bearings under normal operation drain oil from the end compartments to the central compartment compartment A. When the main drain becomes ineffective due to sudden surges of oil to the ends of the chamber the oil passes via auxiliary drainage ducts back to the tank due to the pressure in the chamber. Baffles are provided between the bearings and the end walls of the chamber to prevent the oil sloshing over the entrances to the auxiliary drainage ducts at excessive speed thereby providing tranquil zones from which the oil passes into the drainage ducts.

Title: Apparatus for indicating the quantity of tape on a reel
IPC: G11B15/02
Filed: 1979-04-26
Abstract: When tape is withdrawn from a reel at a constant speed the angular speed of the reel increases as the quantity of tape on the reel diminishes and this is detected by a control circuit 14 sensing increasing voltages derived from the reel and gated to the control circuit by a switching circuit 13, the increasing voltages illuminate a greater number of lamps 15, and the periodic gating causes the illuminated lamps to flash. Adjacent sections of an interrupted annular ring on the disc 10 (rotating with the reel) are held at increasing potentials, and a wiper 1 wipes each in turn as the disc rotates. The switching circuit 13 opens the line from the wiper to the control circuit for a fixed interval during each rotation of the disc so that as the disc accelerates a greater number of sections are wiped during this interval. In a modification (Fig. 5, not shown) a rotating magnet closes a series of switches in turn to generate a series of pulses of increasing voltage which are gated, as before, to the lamps. <IMAGE>

Title: Compensating for zero-point drift in a measurement process using redox or ion-sensitive electrodes
IPC: G01N27/416
Filed: 1980-05-02
Abstract: To compensate the zero-point drifts in continuous measuring processes using redox or ion-sensitive electrodes, a side stream is branched off from the system to be measured and potentiometric measurement is carried out therein in such a way that, after potentiometric measurement of the momentary concentration of the ions to be determined, the zero point is re-determined after complete removal of this ion type with a suitable reagent. Both measurements are best carried out with the assistance of a timer. The system may for example be applied to the measurement of the cyanide ion content of a solution using hydrogen peroxide as the reagent.
