Abstract: ABSTRACT OF THE DISCLOSURE      A method for producing metal by electrolysis in a molten salt bath containing superimposed electrodes, at least one of which is a bipolar electrode.  The arrangement of the elec-trodes creates interelectrode spaces between them.  Bath is swept through these interelectrode spaces.  This method is improved by providing circulation of the bath from one interelectrode space to the next at a location inwards of the peripheries of the electrodes.  This can be accomplished e.g. by boring holes through the electrodes.  It can also be accomplished by breaking the electrodes into individual, mutually separated stacks of electrodes, the circulation of the improvement then occurring e.g. in the space between the stacks.

Abstract: Abstract of the disclosure:      New glycoprotein which can be found in the blood serum and in the extract of human placentas and which can be isolated therefrom and which has the following properties:      a protein proportion essentially consisting of 89 ? 4 % of .alpha.-amino-acids, a carbohydrate proportion of 11.1 ? 2.2%, among it 5.3 ??.1% of hexoses, 2.8 ? 0.5 of N-acetylated hexoseamine, 2.9 ? 0.6% of N-acetylated neuraminic acid;      a sedimentation coefficient S20x of 3.2 ? 0.3 S; a molecular weight of 32 000 ? 6 000; an iso-electric point at pH 4.3 ? 0.3; an extinction coefficient E?cm (280 nm) of 13.8 ? 1.0; an electrophoretic mobility in the range of between that of albumine and .alpha.1-globulins ;      a specific immunologic reaction with an antibody specifically directed against the protein, and a proteolytic activity, as well as a process for isolating it.  In view of its, normally, very low concentration in the human serum, it can be considered as trace protein.  It is suitable for the preparation of anti-serums which themselves may be used as diagnostic agents.  Further-more, it has proteolytic and fibrinolytic properties and a thrombolytic action.

Abstract: BLOWER ASSEMBLY                   Abstract of the Disclosure A blower assembly includes an electric ventilated motor having a through output shaft with a blower wheel attached at each end.  The motor, encircled by a pair of rubber O-rings with the blower wheels attached, is inserted in a blower housing assembly which is split along a horizontal line parallel to the motor output shaft which divides the housing assembly into an upper and lower housings.  The housing assembly contains a central cavity for enclosing the motor and a cavity to either side of the central cavity for enclosing the blower wheels.  The motor proxi-mate and distal walls of the blower wheel cavities contain inlets to allow air to be drawn in by the blower wheels and the blower wheel cavities in the lower housing contain air outlets for the air to be blown out.  The lower housing further contains air passages from the air outlets, to one end of the motor cavity to provide pressurized air to the motor.  With the O-rings blocking passage of air between the motor and the housing, air is forced through the ventilated motor to cool the motor and exits through a motor exhaust in the upper housing proximate one of the inlets to the blower wheel cavity.

Abstract: ABSTRACT OF THE DISCLOSURE A continuous process for the recovery of chemicals in saline water including the steps of converting the sulfates in the saline water feed to sodium sulfate; separating and recovering in the oxide forms essentially all of the magnesium and calcium from the saline water feed; then preparing a sodium chloride fortified solution by mixing the feed with recycled sodium chloride; crystallizing and re-crystallizing and then separating sodium chloride crystals, preferably in two evaporative crystallization processes; stripping bromine from the sodium chloride depleted solution; crystallizing and then separating sodium chloride and sodium sulfate crystals from each other and then from solution; recycling the separated sodium chloride to the first sodium chloride crystallization step; separating residual sulfates from the solution; crystallizing and then separating sodium chloride crystals; recycling the separated sodium chloride to the first sodium chloride crystallization step; crystallizing and then separating potassium chloride from the solution; and recycling the resulting solution to the last sodium chloride crystallization step. Substantial quantities of potable water are produced by the process.   In a preferred embodiment, sodium chloride is electrolytically converted to sodium hydroxide, chlorine and hydrogen.  Part of the sodium hydroxide is used in the process, the remainder is concen-trated and flaked.  Part of the chlorine is liquified, the remainder is combined with a portion of the hydrogen to form hydrochloric acid.  Finally, the steam boiler flue gas may be combined with sodium hydroxide to produce the sodium carbonate used in the process.

Abstract: ABSTRACT OF THE DISCLOSURE:      .     A continuous casting installation has a generally vertical open-ended mold supported on a casting platform, a flexible dummy bar for sealing the lower end of the mold prior to the start of a cast, a curved guide below the casting platform for the strand formed in the mold and a mechanism for handling the dummy bar.  This mechanism includes a carriage which is provided with a semi-circular, downwardly concave roller bed having a length at least equal to that of the dummy bar.  The carriage is located on the casting platform and is movable between the mold and a location above that at which the dummy bar emerges from the strand guide.  A rotatably driven, telescopic arm on the carriage pivots on the axis of the semi-circular roller bed.  The arm is capable of engaging the dummy bar.  In operation, the carriage is positioned above the location at which the dummy bar emerges from the strand guide.  The leading end of the dummy bar is engaged by a hoist as it emerges from the strand guide and is lifted to the level of the casting platform.  The arm on the carriage is extended and engages the leading end of the dummy bar.  Thereafter, the arm is rotated thereby pulling the entire dummy bar onto the semi-circular roller bed.  The dummy bar is then clamped on the roller bed and the arm is disconnected from the leading end of the dummy bar and rotated back to engage the trailing end of the dummy bar.  The carriage is moved to a position adjacent the mold.  Subsequently, the clamping force on the dummy bar is released and the arm is rotated towards the mold thereby lowering the dummy bar into the strand guide via the top of the mold and positioning the dummy bar to seal the lower end of the mold in readiness for another cast.

The pl??e member is precon-ditioned to bow downwardly, away from the casing top, when the ends of the plate member are subjected to inwardly directed forces, as when a pressure buildup occurs within the casing.           The conductors are adapted to break when the relative distance between the terminal and plate exceeds a preselected value.

Abstract: ABSTRACT OF THE DISCLOSURE           An operating device for an electric circuit breaker includes a closing spring and a rotatable spring-controller mounted for rotation between first and second dead center positions with respect to the spring.  The spring is charged by transmitting rotational forces to the spring-controller.  One end of a connecting link is pivotally connected to a point on the spring-controller which is eccentric with respect to the center of rotation of the spring-controller.  Another end of the connecting link is connected to an operating mechanism of the circuit breaker.  Circuit breaker closing is effected by allowing the spring to quickly discharge after a charging operation. Damping means is provided for imposing a damping load on the spring-controller substantially only after it has performed its useful work and is undergoing subsequent oscillations.  The damping means causes the duration of the oscillations to be substantially reduced so that the spring-controller is rapidly brought to rest.  In one embodiment, the damping means comprises a braking member coupled to the connecting link.  In this embodiment, the braking member includes a L-shaped brake support member a portion of which is connected to the spring-controller at the pivot end of the connecting link.  Another portion of the brake support member includes a brake shoe  mounted thereon.  The damping load is automatically exerted by the brake shoe near the end of the spring discharging stroke without the need to transmit forces to any stationary support structure.
