Abstract: ABSTRACT    A miniature, low-wattage, discharge lamp operable on direct current employs substantially parallel electrodes sealed in a single press seal.  The electrodes are configured to provide an arc which is substantially parallel to the longitudinal axis of the lamp with the cathode being substantially longer than the anode.  Heat generated at the anode is dissipated through the seal to the cathode allowing the cathode to operate hot enough to be stable.  The chemical fill for the lamp employs a mol ratio of thorium to cesium to permit good light output and good color rendition.

Abstract: ABSTRACT         A circuit assembly and method of making the same involves locating a flat flexible circuit member with an electrically conducting region defined thereon between a pair of opposed, relatively rigid wafers with a pin conductor inserted through the member and the wafers.  Each wafer includes an aperture extending through the wafer, the aperture of one wafer aligned with the aperture of the other wafer and arranged to abut with the conducting region at the point of desired termination.  The pin conductor is forced into and is retained within each aperture in each wafer, piercing the conducting region on the flat flexible circuit member in the process and making electrical contact with the conducting region. A portion of the pin conductor extends outwardly of one of the wafers for electrical connection to a female connector.

Abstract: ABSTRACT OF THE DISCLOSURE Disclosed are an improved process for preparing com-pressed yeast and the product of that process. Prior to filter-ing yeast, it is conventional to contact the yeast with salt or other osmotically-active material to extract a portion of the intracellular water. Some solids are also withdrawn from the yeast cells; and, unless these are washed away prior to filtration, they tend to clog the filter medium. Our improve-ment concerns washing the yeast prior to filtration and results in increased filtration rates, increased filter medium life, and yeast of improved quality. The product yeast has improved color and plasticity and a lower salt content.

Abstract: ABSTRACT OF THE DISCLOSURE         A resilient closure to be received on a container for a liquid.  The closure has a raised periphery defining a channel to engage on the container to form a seal around the container.  There is a flap in the surface of the closure adjacent the periphery and movable between a closed and an open position but tending to remain closed in the absence of an external force.  A lever is formed integrally with the closure and raised above the surface.  The lever ends generally adjacent the flap.  Downward pressure applied to the lever opens the flap to allow liquids to pass from the container but release of the lever allows the flap to return to the closed position.

Abstract: ABSTRACT OF THE INVENTION         A  unique  design  and  method  of  construction  is presented  for  a  spacer  and  support  suitable  for  use  in maintaining  one  or  more  electrical conductors  at  a  fixed distance from one another while permitting dielectric fluid to flow therebetween.  The spacer is formed from two major parts: a  foraminous  container  and  a  void  filling  means.    The foraminous container defines a plurality of flow apertures around its perphery, and at either end, into which dielectric fluid is free to flow.  The container is filled with a void filling  means   formed  from  a  plurality  of   generally incompressible  filler  elements  or  nodules.    The  filler elements are packed into the container so as to maintain the correct  spacing.     The  nodules  or  filler  elements  are sufficiently  large  that  they  remain  confined  within  the container.   Dielectric  fluid  fills  the  interstices between the void filling means and the container walls.

Abstract: METHOD OF TREATING CARBON-DIOXIDE-CONTAINING NATURAL  GAS            Abstract of the Disclosure A cryogenic separation process for rejecting carbon dioxide from a carbon-dioxide-containing natural gas mixture.  The invention is specifically designed for treating a natural gas mixture recovered from a petroleum well employing the enhanced recovery technique of carbon dioxide flooding.  The carbon-dioxide-containing natural gas mixture is treated using a particular arrangement of fractional condensation, partial vaporization and rectification unit operations to produce an enriched-methane gas stream and carbon dioxide product streams at various pressures.  The invention is well suited for the bulk separation of large quantities of carbon dioxide from carbon-dioxide-containing natural gas mixtures, as a preparatory step for the subsequent purification of the enriched-methane product by conventional absorption techniques.

Abstract: ABSTRACT OF THE DISCLOSURE          Ferric chloride leaching at temperatures in the range 47-74°C is found to remove up to 97% of the uranium from ores occurring in the Elliot Lake area of Canada, but radium removal was found to be poor due to the formation of sulphates from the sulphides present in the ore.  In processes of the invention the sulphides are initially removed by flotation, when aqueous acidic ferric chloride of relatively low concentration, e.g. 0.1 M can extract as much as 92% of the radium, giving tailings which are effectively sulphide-free and with radium levels approaching a desired maximum of 24 pCi/g.  Radium may be removed by adsorption on manganese dioxide and uranium may be removed by liquid extraction with D2EHPA (DAPEX process).  The ferric chloride may be recirculated for further leaching, with reduction before the uranium extraction and reoxidation afterwards.  Because of the recycle, it is possible to keep chloride ion levels in the effluent below the prescribed level in Ontario, Canada of 750 ppm.

Abstract: THERMAL CRACKING OF HEAVY HYDROCARBON OILS   Abstract of the Disclosure A heavy hydrocarbon feed stock is, after being heat-treated in a first cracking zone, introduced into a second thermal cracking zone for obtaining a thermally cracked product and a pitch product.  The second cracking zone has a plurality of cracking reactors which are connected in series, through which is successively passed the treated feed stock and to each of which is supplied a gaseous heat transfer medium to maintain the liquid phase therein at a temperature sufficient for effecting the thermal cracking and to strip the resulting distillable, cracked components from the liquid phase.  The thermal cracking temperature in one reactor is so controlled as to become higher than that in its adjacent upstream-side reactor.  The distillable, cracked components in respective reactors are removed overhead therefrom and separated into a heavy fraction and a light fraction, while the liquid phase in the downstream-end reactor is discharged therefrom for recovery as the pitch product.  The light fraction is recovered as a light product oil, while the heavy fraction is fed to a third thermal cracking zone for obtaining a tar-containing product which is recycled to at least one of the reactors of the second thermal cracking zone.

The digital multi-customer interface utilizes a main processor, control circuit, and multi-customer protocol controller to implement the protocol functions for the communication of packets and control information over individual serial transmission paths.  The multi-customer protocol controller comprises a control processor and a formatter circuit for synchronously communicating packets for a plurality of customer terminals via customer line units and customer lines.  The control processor performs byte-to-packet and packet-to-byte functions between the main processor and the formatter circuit.  The formatter circuit is shared in common by all of the customer lines and performs the functions of assembling and disassembling data bytes from and to individual data bit signals, performing error cyclic redundancy checks and generations, performing flag recognition and generations, and performing bit stuffing and unstuffing.  The control circuit handles communication of all control and status information between the main processor and the customer line units.  The control buffer periodically transmits the control information received from the main processor to all of the customer units and receives back from them status information which is stored for later use by the main processor.
