Abstract: ABSTRACT OF THE DISCLOSURE          A method and an apparatus for catching a partly fibrat-ed mineral bloom which is thrown out from rotating fibrating wheels which are supplied with a mineral bloom.  The catching of the partly fibrated mineral is effected by one or several jets or flows of a liquid medium, especially water, which are directed at the fibres at an angle to the outflow direction of the fibres from the fibrating wheel or wheels.  The liquid flow or flows can be provided in one or several sets completely or partly extending round the periphery of the fibrating wheels.  The liquid flows can be flat or bowformed jets which are provided so as to comple-tely surround the periphery of the fibrating wheels.  By means of the liquid flows the partly fibrated mineral is moved away for further treatment, especially for separating fibres from non-fi-brated particles, so called "pearls".

Abstract: IMPROVED ASYMMETRIC MEMBRANES AND PROCESS THEREFOR     ABSTRACT OF THE DISCLOSURE:         There is disclosed, in one aspect, an improved highly asymmetric  membrane comprising a skin and a porous asymmetric support.  The skin contains pores which have an average pore diameter from about 0.005 to about 3.0 microns and this asymmetric support comprises a reticulated structure which con-tains pores which have pore diameters of from about 10 to about 20,000 times as large as the average pore diameter of the pores of the skin. The membrane has a bulk porosity greater than about 70%.  In another aspect, there is disclosed a process for prepar-ing these membranes.  This process comprises casting a polymer dope while the dope is in an unstable liquid dispersion condition.          The concentration of polymer in the polymer dope should be high enough to produce a coherent membrane yet low enough to form a substantially all-reticulated structure within the asymmetric support.  The membranes are characterized by high flow rates, excellent retention properties, and improved resistance to fouling

Granted: 1984-01-03
Abstract: ABSTRACT OF THE DISCLOSURE A process is provided for producing oxalyl chloride by first photochemically chlorinating ethylene carbonate to form tetrachloroethylene carbonate and hydrogen chloride and then decomposing the tetrachloroethylene carbonate to oxalyl chloride and phosgene.  The chlorination reaction is performed in a reaction vessel having an illuminated side arm conduit of narrow cross-sectional area.  Chlorine is introduced at the base of the conduit and together with the hydrogen chloride evolved in the reaction continuously circulates the ethylene carbonate-chlorine reaction mixture through the narrow reaction zone within the conduit.  The temperature of the ethylene carbonate-chlorine reaction mixture is controlled in the range of 70 to 100°C, preferably in the range of 79 to 81°C.  The tetrachloroethylene carbonate is decomposed by heating same with a catalytic amount of a tertiary amine or amide.

Abstract: A B S T R A C T            The invention relates to a method for detecting and measuring alpha-emitting substances, such as radon and/or daughter products of radon, by registering nuclear tracks on a detector. By contucting away during measuring any electrostatic field which may have built-up on the detector, there is eliminated the risk of erroneous informa-tion being obtained with respect to the dosage of radiation received.          A device in the form of a dosimeter for carrying out the detecting and measuring method is also provided in accordance with the inven-tion. Arranged on or in the immediate vicinity of the registering surface (1) of the detector is an electrically conductive material (2) which at least partially covers the registering surface. In a preferred embodiment, the dosimeter may include at least one ab-sorber (4) arranged between the registering surface and the elec-trically conductive material. The electrically conductive layer suitably has a constant potential and may be connected to the ground or to a source of electric voltage (Fig 4).   The present invention provides advance in the art by avoiding the disadvantage common with the use of nuclear radiation registering detectors such as cellulose nitrate, in personal dosimeters, for registering radon and radon daughters, namely that the dosimeter can give erroneous information concerning the dose obtained by the wearer regardless whether the detector is uncovered or covered.

Abstract: RCA 75,275 ABSTRACT OF THE DISCLOSURE          A side pincushion corrected deflection circuit for a television receiver includes a deflection winding, a trace capacitor and a first switch for generating scanning current in the deflection winding.  A modulator circuit includes a modulator inductor and capacitor and a second switch for generating a sawtooth modulator current in the inductor. The trace and modulator capacitors are charged from a B+ operating voltage source through the primary winding of a flyback transformer.  A transistor stage in the modulator circuit shunts current away from the modulator capacitor to control the modulator and trace capacitor voltages.  A vertical rate bias voltage is applied to the transistor stage and varies the shunt current at a vertical rate in a parabolic manner to provide side pincushion correction. Under fault conditions, such as an open-circuited deflection winding or trace capacitor, the modulator capacitor voltage tends to undesirably increase above the peak voltage developed under normal operating conditions.  To prevent overstressing the modulator transistor stage, a diode clamp is coupled between the modulator capacitor and a source of reference voltage, thereby preventing the modulator capacitor voltage from substantially exceeding the reference voltage level.

Abstract: TITLE OF THE INVENTION          Door-Locking Mechanisms for Security Enclosures ABSTRACT OF THE DISCLOSURE            The locking mechanism for a vault door has a plurality of independently  negatable locks, each one coupled through its bolt to a respective pivoted locking arm. In the locking condition the arms are pivoted to block withdrawal of bars carried by the main boltstraps.            Each lock bolt is connected to its arm by a rotatable control member having a lobe and an eccentric peg which engages in a slot in the respective arm. To negate a lock its bolt is thrown and a lever turned to rotate the respective control member.  This places the lobe next to the lock case and pivots the locking arm into its unblocking position.            If the door is left open with the boltwork withdrawn and unlocked unauthorised negation of a lock cannot take place because there is insufficient space to rotate the respective control member without the latter abutting the lock case.  If the door is left open with the boltwork thrown and locked unauthorised negation might occur if access is gained to the mechanism, but this will be immediately apparent when the bank staff come to close the door at the end of the day as this procedure first involves withdrawing the lock bolts and the bolt of the negated lock will be blocked by the proximity of the control member lobe to the lockcase.
