Abstract: Abstract of the Disclosure This invention is directed to a process for removing oils and petroleum hydrocarbons from the surface of the sea, particularly from shoals.  These oils or petroleum hydrocarbons are those that are left behind after the majority of the oil floating on the water has been pumped away or otherwise removed.          The processes is characterised in that metabolites of microorgan-isms which reduce the surface and interface tension of the oil or petroleum hydrocarbon/aqueous phase system are applied to the layer of oil remaining on the surface of the water, and the oil caking together is removed therefrom.

Abstract: ABSTRACT OF THE DISCLOSURE     Apparatus for separating a comixture of light and heavy materials includes a drum divided into two sections.          In the first section, the material is introduced with a fluid, and separated from the fluid such that the fluid flows substantially the length of the first section along a "counter flow" path to wash against the material to be separated before overflowing the first section.  The material to be separated separates into floating and sink-ing fractions, the floating fraction overflowing the first section together with the fluids.  The sinking fraction is carried by a scroll along the wall of the first section to be lifted into the second section.  In the second section, the sinking fraction is reduced in size by a charge of grinding balls and lifted and removed from the second section.

Abstract: Abstract of the Disclosure This invention is a revolving examination table apparatus to be used by, for example, optometrists during an eye examination to place a desired instrument between the patient and the doctor.  More particularly, the table apparatus includes 1) a main, circular support base assembly; 2) a revolving table top assembly rotatably mounted on the support base assembly; and 3) an electrical control and drive assembly operable to control rotation to the revolving table top assembly.  A central portion of the support base assembly and the revolving table top assembly is cut out to receive a chair and person (optometrist) therein while the patient sets opposite therefrom with the table apparatus therebetween.  The electrical control and drive assembly operates to 1) rotate the table top assembly to one of seven stations and stop automatically; 2) supply electrical power to each station when in the usage position to an electrical receptacle to power an instrument at that station; 3) control direction of table top assembly rotation; 4) control speed of subject rotation; and 5) provide an override switch to by-pass a station, if so desired.

Abstract: HIGH PRESSURE CUTTING NOZZLE    WITH ON-OFF CAPABILITY       Abstract An ultra high pressure water jet cutting nozzle is disclosed which comprises a lightweight poppet valve assembly coupled by a lost motion connection to a valve actuator.  The poppet valve assembly seals directly to the jet-forming element of the nozzle insuring continuous high pressure fluid in the system at all times.  The maintenance of constant high fluid pressure in the system protects the supply tubing of the system against damage due to pressure waves generated by repeated opening and closing of the valve assembly.  The maintenance of continuous high fluid pressure also prevents dislodgement of the jet-forming element of the nozzle.

Abstract: III.  ABSTRACT             Apparatus for monitoring and storing heart activity signals is disclosed as including a data processor illustra-tively in the form of a digital microprocessor.  The monitoring and storing apparatus comprises a memory comprising first and second pluralities of storage locations, a circuit operating in a real time frame for sampling at a regular rate the patient's heart activity and for storing such sample signals in corre-sponding locations of said first plurality, and the data pro-cessor for processing the signals stored in the first plurality and for storing the processed signals in selected locations of said second plurality.  The storage of the signals in the second plurality is performed in a second computer time frame and at a rate faster than the real time sampling rate.  A sam-pling clock provides a sampling clock signal to the sampling circuit whereby the samples of the patient's heart activity are taken.  A second computer clock provides computer clock signals to at least a portion of the data processor whereby the processing of the heart activity is effected in the rela-tively fast computer time frame.  The data processor comprises a first portion or means that operates in response to the sample clock signal for evaluating the heart activity signals to determine the existence of a valid heartbeat and a second portion operating in the computer time frame for processing the detected heartbeat and in particular for determining the interval therebetween, which is evaluated to determine whether the heartbeat is occurring with a regular rhythm or not.

Abstract: Abstract A document distribution terminal is organized with two supervisory processing units, one to control the data entry and data printing and the other to control the terminal.  Each of these processing units only performs control functions.   All of the data processing is performed by various specialized devices preparing the document data for transmission or for printing.  Further, the terminal is organized with two interfaces and an adapter coupling the two interfaces.  The terminal-controlling processing unit supervises one interface that interconnects all of the specialized devices.  The other processing unit, that controls the data entry and data printing devices, supervises the second interface.  Once the supervisory processing units have set up a job in the terminal, the data transfer across the two interfaces is substantially under the control of logic in the adapter.
