Abstract: BIOLOGICAL FLUID ASSAY SYSTEM AND METHOD    ABSTRACT       A biological fluid assay system and method for the determination of immunoreactive characteristics of bio-logical specimen and more particularly for the qualitative determination of immunological reactions.  The apparatus includes a centrifuge rotor, a disposable belt mountable on the centrifuge rotor, and a plurality of light trans-missive chambers as components of the removable belt, each of the chambers having a vertical apex and a horizontal radial apex for accepting a sample comprising a specimen and an appropriate reagent.  An illumination system projects an image of the sample while a linear photosensi-tive array detects the image of the sample for measuring the vertical dimension of the sample and a microprocessor analyzes the vertical dimension of the sample.  A sample is radially accelerated to compress the particulate portion of the sample or reagent into a compact mass in the extreme radial portion of the transparent chamber. The centrifugal force on the sample is balanced with the gravitational force acting on the compact mass by decel-erating the rotor.  The vertical dimension of the compact mass is measured while the sample is rotating.  The vertical dimension of the compact mass is again measured after a delay to determine the presence of vertical streaming.  The difference between the vertical dimension of the compact mass before streaming and the vertical dimension of the mass after streaming is completed, due to gravitational attraction, is determined.

Abstract: X-ray Tube Filament Energization Method and Apparatus Abstract An X-ray tube filament energization method and apparatus with a filament energizing transformer mounted inside an X-ray tube housing while a high voltage gener-ating transformer remains outside that housing.  This arrangement allows a single high magnitude negative polarity input to be routed through the tube housing and coupled to the tube cathode.     In one embodiment of the invention two cathode filaments are each energized when in use by an assoc-iated one of two filament transformers inside the housing. Selective energization of one or the other transformers determines which filament is to be energized.  In an alternate embodiment a frequency sensing electronic switch chooses which filament to energize depending on the energization frequency input to a single filament transformer.

Abstract: ABSTRACT         A process for the recovery of cyanide from thiocyanate.  An aqueous solution containing thiocyanate is introduced into an electrochemical reactor.  The reactor is activated for an appropriate time period while the pH of the solution is maintained in the range of 1 to 4.  The cyanide formed can be recovered, in various ways including recovery as hydrocyanic acid.          Where desired, the thiocyanate can be oxidized in the reactor for a longer period while the pH of the solution is maintained in the range of 10 to 12, to produce relatively harmless products, for example cyanate, ammonia, carbon dioxide and nitrogen.       The process is particularly useful to process thiocyanate containing wastes produced in the processing of gold and silver ores and concentrates, unit operations related to base metal processing, coking operations and petroleum refining.

Abstract: ABSTRACT OF THE DISCLOSURE     Electrically  powered  trolley  vehicles  in headings of  mines  are  provided  with a current  collector pick-up unit having contact-sensing means, current collectors, position  sensors  and  guide  wheels.   The  power  supply for the  pick-up unit  comprises  an  array of elongated guide rails and at least two conductor bars.  The connect-in method comprises running the vehicle slowly forwards, by means of its own energy source,  in the direction of the elongated conductor bars and vertically raising the pick-up unit by means of an arm mounted on the vehicle so that a contact-sensing frame for sensing contact  in a  vertical  direction  is  brought  into  engagement  with one or both of the guide rails.  During a continued verti-cal movement,  the  contact-sensing frame is turned down towards the rest of the pick-up unit and when the contact-sensing frame reaches its lower end limit position, this is  indicated by a position  sensor.   The pick-up unit is then turned in the lateral direction until contact-sensing  bars  for  horizontal  sensing  are  brought  into engagement with the nearest guide rail.  When the position sensors indicate this, the frame is lowered and the pick-up  unit  with  its  current  collectors  and  guide wheels is raised towards the conductor array, whereby the current collectors are brought  into contact with the conductor bars and the guide wheels are brought into contact with the guide rails.

Abstract: ABSTRACT OF THE DISCLOSURE             An adjustable conical atomizer comprises a body part having an end or discharge face with a conical recess and a conical plug having a complementarily conically-formed surface which is adjustably positioned in the conical recess. The size of the cavity formed between the plug and the body is varied by changing the relative positions of the plug and the body, for example,by using an indexing bolt which connects the body part and the plug parts. The body or a connection to the body is provided with channels or passages for the passage of two or more fluid streams into the space between the plug and the body part for intimate mixing therein. The fluid stream includes a liquid which is accelerated in this zone between the body and the plug. The plug and the body form an annular discharge therebetween which diverges in an outward direction.

Abstract: ABSTRACT               METHOD AND APPARATUS FOR   ECG RHYHM ANALYSIS       A method and apparatus for automatic rhythm analysis of digitized ECG signals.  Candidate heartbeats are detected and the noise of the ECG signal portion containing the candidate is evaluated to determine whether the candidate is a valid nominal or noisy beat or an invalid noisy saturated signal.  The timing of detected heartbeats, both noisy and nominal, are determined relative to prior validated heartbeats.  Features of the detected heartbeats are automatically extracted including onset, offset and R wave locations; QRS complex width; R-R interval based on the onset points; instantaneous and averaged heartrates; and others.  A 16 point template of the heartbeat starting at the onset is also determined. Beats are then classified in a two step process; first, by template -comparison with a previously determined dominant template, and second, by a finite state machine process based on the results of the template comparison and relative timing of the beat.  As a result of the two step classification beats are classified as belonging to a plurality of beat types including both single and sequence beat types.  A class record for each beat type is created and stored, any portion of which is accessible for display upon demand.
