Inventor: ELLIOTT LEONARD GODFREY
IPC: B01J4/02
Filed: 1981-04-17
Abstract: Liquid additives can be supplied to a fermenter vessel from a reservoir by a dispensing device which comprises a central discharge chamber connected in series between an upper escape chamber and a lower inlet chamber. These chambers are arranged to provide a smooth passage for liquid and do not have any steps or recesses therein. An escape port leading from the upper end of the escape chamber to the reservoir is controlled by a valve member. An inlet port leads into the lower end of the inlet chamber from the reservoir and is controlled by a valve member. A discharge port leads from the bottom end of the discharge chamber and is controlled by a valve member. A pressure equalizing port leads to the top end of the discharge chamber and is controlled by a valve member. The discharge and pressure equalizing ports are connected to the upper portion of the fermenter vessel. The escape chamber is capable of retaining liquid therein by interfacial tension while liquid is discharged from the discharge chamber. If desired, the discharge chamber may be divided into a plurality of sub-chambers.

Abstract: 1. A differential tripping device in which the tripping energy, supplied to a polarized tripping relay (20) is generated by the secondary winding (18, 36) of a differential transformer (10) by a differential fault appearing in primary windings (14, 16) of the differential transformer (10), the winding (26) of the polarized relay (20) being connected to said secondary winding (18, 36) by a full-wave rectifier (19, 34) with diodes (D1, D2) characterized in that said winding (26) of the polarized relay, having an inductance and a time constant allowing, when a pulsating fault current occurs, a successive accumulation of energy at each pulse for a tripping control for a predetermined threshold and a quasi-instantaneous tripping control, when a continuous fault having a higher value than the threshold, suddenly occurs.

Patent FR-2501316-A1 (FR)
Inventor: DOSTAL JAN
IPC: F16D57/04
Filed: 1982-03-03
Abstract: The invention relates to a hydrodynamic brake which is intended to produce a reduced braking torque in the disengaged operating condition. For this purpose, a groove is formed in a fixed blade wheel, the said groove opening into the working space. Arranged in this groove is a coaxially displaceable orifice which is firmly connected to a piston which is supported in a cut-out in the fixed blade wheel and has an inner and an outer sealing ring. Supported against the end wall of the piston are springs which, in the disengaged condition, push the orifice into the working space and form an obstacle to the flow of the air and oil mist in order thereby the reduce the braking torque. In the engaged condition, the pressure fluid forces the orifice out of the working cavity into the groove such that it does not hinder the flow of the fluid in the working cavity.

Title: Electronic voltage regulator fault indicator for motor vehicles - uses integrated circuit with comparators to detect alternator or regulator failure and to give different signals for respective faults
Inventor: CONSTANTINESCU GHEORGHE
IPC: H02J7/14
Filed: 1982-03-03
Abstract: The unit comprises four comparators (1,2,3,4) integrated on the same base. The first (1) is used to control the power amplifier (6) which drives the alternator excitor coil, and the other three (2,3,4) drive, through a medium power stage (16) the three comparator outputs. These outputs control a impulse generator (9) to produce the various fault indications (8). The three warning indications are distinguished by the associated warning blinking at either one frequency, or twice that frequency and thirdly remaining lit continuously. The arrangement provides an indication of overvoltage, undervoltage and zero output from the alternator, as may result from the breaking of the drive belt.

Inventor: SEILLY ALEC HARRY
IPC: H03K17/04
Filed: 1982-03-12
Abstract: A control circuit for controlling the operation of an electromagnetic device consisting of a solenoid (12) and an armature comprises a transistor switch (13) which is connected in series with the solenoid (12) and DC supply terminals (10, 11), a Zener diode (16) which is connected in parallel with the transistor switch (13), and a solid-state switching device (14, 15) which is provided in parallel with the solenoid (12). The operation of the solid-state switching device (14, 15) and of the transistor switch (13) is controlled by a control circuit (17). The transistor switch (13) is opened and the switching device (14, 15) is closed in order to maintain the current flow in the solenoid (12), the transistor switch (17) being pulsed in order to maintain a mean current flow. When it is intended to deenergise the solenoid (12), the transistor switch (13) and the switching device (14, 15) are both opened and the Zener diode (16) conducts in order to protect the transistor switch (13) against a high voltage which is induced in the solenoid (12), and in order to consume the stored energy of the magnetic circuit of the solenoid (12).

Filed: 1982-07-05
Abstract: In a process for producing encapsulation tubes for nuclear reactor fuel rods, a zirconium-base alloy is extruded at a temperature below 680 DEG C and the extruded material (product) is cold-rolled. Between the individual cold rollings, intermediate annealings are carried out, at least one of which takes place at a temperature which exceeds 650 DEG C in the  alpha -phase range. The final cold rolling is followed by a final annealing. According to the invention, the extruded product is cooled after every intermediate annealing exceeding 650 DEG C at a rate which is at least 5 DEG C/minute in the temperature range from the annealing temperature down to 650 DEG C before it is subjected to the next cold rolling. Annealings which take place after the final intermediate annealing at a temperature above 600 DEG C in the  alpha -phase range are carried out at a temperature of not more than 600 DEG C. The encapsulation tubes produced in accordance with the invention have not only a high corrosion resistance but also good mechanical properties.
