Abstract: Abstract                                       C-I-L 642 Primer Assembly A primer assembly is provided for use in vertical boreholes wherein the primer charge is initiated by means of electric blasting caps, the electric caps, in turn, being initiated electromagnetically.  A covered, cup-shaped primer assembly contains a toroid transformer element and connected electric blasting cap in detonating relationship with a primer explosive charge.  The assembly is arranged to receive therethrough a looped wire conductor which conductor passes freely through the toroid transformer.  When an energy source is coupled to the looped conductor, a magnetic flux is induced in the toroid transformer which sets off the cap and primer charge.  The assembly may be passed freely or slid along the looped conductor to any location in the borehole. The assembly permits the use of electric time-delay, deck-charge blasting without the usual hazards associated with normal electric cap blasting.

Abstract: ABSTRACT OF THE DISCLOSURE    A densimeter for measuring the density of liquids is disclosed. The densimeter comprises a substantially vertical shaft having a central axis.  The densimeter further comprises a motor for rotating the shaft about its axis and a vessel mounted on the shaft asymmetrically with respect to the shaft axis.  A counterbalance is provided on the shaft for at least partly compensating for the asymmetry.  The shaft is resiliently mounted with freedom of oscillation transverse to the shaft axis.  A measuring device is provided for measuring the amplitude of the oscillations, this being proportional of the deviation of the specific gravity of the sample from a reference value.  The measuring device comprises a slotted drum carried by the shaft and acting to shutter two light beams as the shaft rotates.  Two waveforms are generated and a device measures the phase shift between the waveforms, this being indicative of the amplitude of the oscillations.  Instead of a discrete sample, a continuous flow of liquid may be measured, the liquid passing to the vessel through one of two concentric tubes forming the shaft and the liquid returning from the vesel via the space between the two tubes.

The charge is fed into the reactor on one side thereof onto the molten bath in a melting zone so as to maintain an oxidation potential which causes metallic lead and slag to be formed.  Reducing agents are introduced into the slag phase on the other side of the reactor in a reducing zone.          To ensure that the bismuth contained in the charge will be collected in the smallest possible quantity of crude lead, such an potential is maintained in the molten bath in the melting zone that the lead phase contains 0.05 to 2 % by weight sulfur, the high-Bi primary lead which becomes available in that zone is separately tapped, and the low-Bi secondary lead which becomes available in the reducing zone is also separately tapped.

Abstract: ABSTRACT      A colour cathode ray tube display apparatus is provided with compensation for errors due to interfering magnetic fields in which a deflection yoke causes the electron beams to raster scan across the tube, a convergence assembly on the neck of the CRT adjusting the beam convergence.  Errors in the waveforms supplied to the radial convergence assembly are due to high frequency magnetic field coupling between the yoke and the convergence assembly via the internal magnetic structure (7) of the CRT.      A compensating coil (11) placed adjacent the affected convergence coil unit (12, 16) supplies compensating current through resistor (20) to the amplifier (15) driving that convergence coil unit, thus avoiding a fringe on the left-hand side of the screen.      Alternatively, compensating current can be derived from the line flyback pulse or the logic signal initiating line flyback.

Abstract: ABSTRACT OF THE DISCLOSURE            The invention relates to SERUM-DERIVED "LEUKORE-CRUITIN", which is A PROTEIN MEDIATOR OF INFLAMMATION          FROM MAMMALIAN SERUM specifically inducing positive leukocytosis reaction and leukocyte recruitment from the bone marrow into the blood of animals and humans without biological side-reactions. The process for the production and isolation of leukorecruitin is characterized in that mammalian serum is subjected to regulated and limited proteolysis by contact activation,  the protein is then separated from other foreign constituents and proteins of serum in the form of a crude serum protein concentrate fraction, and/or the protein is separated from other serum-proteins by chromatography on hydroxy-apatite. Leukorecruitin has very valuable pharma-cological effects and can be used in compositions for specifically influencing the defense state of the animal or human body  and for diagnostic pur-poses in hematogolical disorders.

Abstract: Abstract:  Titania Oxygen Sensor With Chrome Oxide Compensator An oxygen sensor utilizes a chrome oxide compen-sating  resistor  (5)  in  series  with  a  titania  sensing resistor  (3).    The  chrome  oxide  resistor  (5)  not  only compensates for the effects of temperature on the titania sensing  (3)  resistor,  but  since  it  exhibits  (p)  type behavior  while  the  titania  exhibits  (n)  type  behavior in  the  presence  of  gaseous  oxygen,  the  sensitivity  of the  sensor  is  increased.   The  resistors  (3,  5)  can be applied  as  a  film  to  a  substrate  (7)  or  they  can be formed  as  discrete  chips.     Substantial  quantities  of alumina and glass can be added to the chrome oxide without affecting   oxygen   sensitivity   although  the  electrical resistance rises substantially.

Abstract: METHODS AND APPARATUS FOR FABRICATING A         LIGHTGUIDE PREFORM            Abstract Undeposited reactants passing through a glass substrate tube, during the fabrication of a lightguide preform by the Modified Chemical Vapor Deposition (MCVD) process, flow into a reactant exhaust system and are carried therethrough by a uniformly flowing reactant-free gas.  The reactants pass through an exhaust tube, a reactant collection chamber, through a pressure control apparatus and into a gas scrubber.  The pressure within the exhaust system is maintained substantially constant during the MCVD process by continously monitoring the pressure therein and adjusting the pressure control apparatus accordingly.  Additionally, a continous, uniform flow of reactant-free gas is directed into the exhaust system to assist in the removal of the undeposited reactants therefrom.

Abstract: POLARIZATION-INSENSITIVE OPTICAL SWITCH        AND MULTIPLEXING APPARATUS               Abstract of the Disclosure Polarization-insensitive optical switch and dual channel carrier multiplexer includes a polarization beam splitter for receiving an input collimated beam which has arbitrarily polarized components, splitting the beam into the two components.  One of the components is rotated by a 1/2 wave plate so as to yield a polarized beam which is polarized in the same direction as the other beam.

The output of the interferometric multi-mode fiber optic switch and modulator contains two beams, both polarized in the same direction.  One of the beams is rotated ninety degrees by a 1/2 wave plate, and the two mutually perpendicularly polarized beams are then recom-bined by a polarization beam splitter operated in reverse to yield an output beam containing mutually perpendicular components.
