Patent FI-97796-C (FI)
Inventor: BRENNER RICHARD
IPC: B66B1/20
Filed: 1988-12-30
Granted: 1997-02-25
Abstract: In this process for managing passenger traffic at the main stop (HAUPTHALT) of a lift group with n lift cages, sensors (SENSOR. A; SENSOR. B ... SENSOR. N) monitor entering passenger traffic and sensors (SENSOR. 1; SENSOR. 2 ... SENSOR. N) monitor exiting, building-filling passenger traffic. The higher-order algorithm (REGLER) implemented in the processor (RECHNER) determines the traffic volume and the actual departure load of the lift group from the sensor data. Depending on the traffic volume, the actual departure load and constants imported from the input/output unit (TERMINAL), the higher- order algorithm calculates the carrying capacity of the lift group according to a control algorithm. The carrying capacity of the lift group is assigned to the lower-order algorithms (REGLER. 1; REGLER. 2 ... REGLER. n) according to the number of lift cages and the nominal load of the relevant lift cage. The lower-order algorithm of the relevant lift cage calculates the optimum departure load on the basis of the assigned carrying capacity and the circulation time of the relevant lift cage. Depending on the optimum departure load and the actual departure load of the relevant lift cage, the lower-order algorithm determines, according to a control algorithm, the adjusted departure load which is to be imposed on the relevant lift cage.

Abstract: This cylinder (1) is covered by a combination of two metal sleeves (3, 4) forming two superposed cylindrical layers and chosen from materials such that the inner sleeve (3) has a coefficient of expansion greater than that of the outer sleeve (4) in contact with the molten metal; the differential thermal expansion experienced by the two sleeves (3, 4) during casting of the molten metal prevents the cylinder (1) from bulging and, consequently, guarantees the production of cast products having a satisfactory thickness profile. Application to the continuous casting of molten steel. <IMAGE>

Filed: 1990-04-03
Granted: 1995-09-12
Abstract: A magnetron is powered via an output transformer TR whose primary winding (a) is connected in series with a resonant converter oscillator circuit comprising an inductor (L) and a capacitor (C3) and switching transistors (T1, T2) which are connected to positive and negative power supply terminals and are switched by respective current transformers (CT1, CT2).  The switching points of the switching transistors are varied so as to vary the output of the circuit by varying the positive and negative flux excursions in the cores of the transformers (CT1, CT2) such that the net flux excursions are sufficient to saturate the transformers and switch off the switching transistors at a predetermined point in each half cycle.  The relative positive and negative flux excursions in the transformer cores are controlled by providing additional winings (g) which are connected to a control circuit which rectifies the output of these windings and controls the rectified DC voltage appearing across them.

Abstract: An insulating roller cover is now disclosed that provides a highly desirable combination of features. The cover is free from asbestos and is therefore of more desirable construction for handling and use. For the roller cover, at least substantially ceramic fiber is highly compressed, providing a dense and refractory, elevated temperature resistant insulating cover.  The cover may itself serve as a load bearing surface; or may provide a foundation or protective media for annular discs or 10 sleeve members made of various, load bearing materials.  These load bearing materials may be unable to resist direct contact with the shaft due to thermal shock or the differences in their respective expansion and contraction rates.  Where impregnant is utilized with the highly compressed fiber, such will often comprise a colloidal substituent.

Abstract: Electrical heating systems for mineral wells, particularly oil wells, in which the reservoir or "pay zone" is heat stimulated or some well components (e.g., the tubing) are heated, or both, by electrical power supplied to a multi-perforate electrode have the operating efficiency enhanced by effectively  terminating the heating electrode, at both its top and bottom, at a distance inwardly of the pay zone equal to at least three times the diameter of the well casing.  In some systems the electrical power connection to the main heating electrode is made through a section of the production tubing of the well, with an electrical contactor interconnecting the tubing and the electrode in the level of the pay zone; these systems also provide electrical isolation, within critical height limits, for the production tubing and the pump rod.  Delivery of electrical power downhole of the well may be accomplished through an electrical cable, which may or may not be appropriately armored.  Specific electrode constructions combine conductive and insulating materials to counteract galvanic corrosion while maintaining mechanical strength.
