Patent BE-892404-A (BE)
Title: Rigid coupling for helical-rotor volumetric pump - uses flexible conical rod allowing axial and radial connection without rotation and has endless thread at extremity
IPC: F04C15/00
Filed: 1982-03-08
Abstract: The rotor rotates eccentrically w.r.t. the longitudinal axis of the external stator which is of synthetic rubber with a threaded internal surface. A flexible coupling rod connects the rotor to the drive shaft with a baffle ring and washer. Each end of the coupling rod is of conical shape with an external thread and a shoulder to distribute the coupling stresses near the end of the thread. A tapered axial recess in the end of the drive shaft accepts the threaded end of the rod and is provided with a cylindrical threaded collar. A connecting piece is double-bored with two internal threads which correspond to those of the rod and collar, and may be protected by a dust-excluding ring.

Abstract: POWER CIRCUITS FOR OBTAINING A              HIGH POWER FACTOR ELECTRONICALLY                  Abstract of the Disclosure Solid state chopper circuits for alternating-current or direct-current loads use only high frequency filtering and electronically shape the line current to obtain a high power factor.  The control circuit generates a reference signal which is shaped according to a selected control function and also determines the input power.  By comparing a sensed instantaneous power current with the reference signal, as by using a comparator with hysteresis, a solid state switch in the chopper circuit is operated at a high frequency chopping rate to shape the power current and therefore the line current. An application is a ballast for a gaseous discharge lamp.  The preferred circuit is a signal phase transistor or gate turn-off thyristor d-c chopper fed by rectified unfiltered line voltage with a force load current wave-shape for high power factor and good regulation.

Abstract: ABSTRACT OF THE DISCLOSURE        A ghost signal erasing system for television receivers in which a variable delay element utilizing the propagation of an elastic surface wave is used as a delay circuit.  The variable delay element includes a piezoelectric substrate, a plurality of first interdigitated electrode pairs formed on the substrate and a plurality of second interdiginated electrode pairs also formed on the substrate.  An elastic surface wave produced by applying a video i-f signal to the first interdiginated electrode pairs is propagated along the surface of the piezoelectric substrate and taken up at the second interdigitated electrode pairs as a delayed a-c signal.  By switching the first and second interdigitated electrode pairs to change the combination thereof, various delay times are obtained.

Abstract: AN IMPROVED BLOOD OXYGENATOR     ABSTRACT OF THE DISCLOSURE     There is disclosed a blood oxygenating device having an oxygenating chamber and a heat exchange chamber The oxygenating chamber consists of a bubbler chamber and a mixing chamber.  Oxygen is introduced into the bubbler chamber through a porous diffusion means situated near the inlet of the bubbler chamber.  Bubbles pass from the bubbler chamber into a mixing chamber which is provided with a plu-rality of secondary flow-producing deflectors to promote secondary flow of blood bubbles passing therethrough.  The secondary flow results in a highly efficient oxygen-carbon dioxide transfer. The blood bubbles are then passed through a heat exchange chamber and a defoaming means prior to exit-ing the oxygenating device.

Abstract: ALTERNATING CURRENT LIQUID LEVEL INDICATOR            Abstract of the Disclosure An oscillator has its output coupled to a control element of a switch as well as to a probe.  When the probe is in contact with liquid in a container, it is essentially grounded so that the switch is turned off. When, however, the liquid level falls below the probe, the oscillator output signal turns on the switch, which in turn illuminates an indicator lamp.  A pair of latching circuits are connected from a point between the lamp and the switch to the oscillator and to the switch contact element and serve to bias the switch on and turn the oscillator off once the lamp has been illuminated.
