Abstract: 44.273 TOTALIZER APPARATUS FOR RECORDING TWO DATA INPUTS ON A SINGLE CHANNEL                      Abstract A totalizer receives the output signals from two different sources, each generating signals repres-entative of a measured event, such as the consumption (or transmission) of electrical power.  The totalizer generates a train of recording pulses at a predetermined "offset" repetition rate.  The totalizer increases the repetition rate of the recording pulses above the offset rate in response to an increase in the repetition rate of signals received from one of the sources; and it decreases the repetition rate of the recording pulses below the offset rate in response to an increase in the repetition rate of signals received from the other source.  Thus the totalizer provides a bidirectional capacity in that it records events from two sources on a single data channel.

Abstract: "HOMOGENIZER/SUBSAMPLER FOR TAR SAND PROCESS STREAMS"             ABSTRACT OF THE DISCLOSURE           An apparatus and process are described for homogenizing and subsampling process streams such as those present in the hot water extraction process for recovery of bitumen from tar, sand.  Such streams contain widely variable proportions of heavy oil, water, and solids.  To obtain a representative analysis-size subsample from such a stream, a bulk sample is taken into a cylindrical open-topped vessel containing a coaxial cylindrical draft tube spaced from the internal wall of the vessel.  A head element closes and seals. the top of the vessel.  An impellor extending into the draft tube through the head element is actuated to circulate the bulk sample along an elliptical flow path within the vessel.  The vessel contents are maintained in a pressurized condition by the introduction of inert gas.  A subsample is taken by mechanically opening and closing a sample port extending through the side wall of the vessel and communi-cating with the flow path; the subsample is thus taken while the bulk sample is in motion and the components of the mixture are in a homogenized condition.

Abstract: ABSTRACT A resilient plastic web exhibiting a fiber-like appearance and tactile impression and method and apparatus for its manufacture.  In a preferred embodiment, the web exhibits a three-dimensional microstructure comprising a regulated continuum of debossed areas of non-uniform cross-section along their length.  In a particularly preferred embodiment, the debossed areas comprise capillary networks interconnecting the first and second surfaces of the web, said networks being of decreasing size in the direction of said second surface to promote fluid transport from the first surface of the web to the second surface and inhibit the flow of fluid in the reverse direction.  Forming surfaces utilized to produce said webs are constructed by laminating a multiplicity of thin plates having dissimilar patterns of apertures therein to form an integral structure exhibiting properties and characteristics unachievable by prior art machining and weaving techniques.  In a particularly preferred embodiment, the individual laminae from which the laminate forming structure is comprised are produced utilizing photoetching techniques, thus making it feasible to produce nearly any desired level of intricacy in the resultant laminate structure. Preferred means for interconnecting said laminate structures with one another without disrupting the three-dimensional pattern in the area of joinder are also disclosed.

Abstract: ELECTRIC CONNECTOR ASSEMBLY               ABSTRACT The invention relates to a connector assembly consisting of an elastomeric insert member held within a rigid shell by a retaining ring which engages both the shell and the insert.  The assembly in-cludes a passageway between the insert member and the shell permitting access to the retaining ring to allow ready disengagement of the ring and insert from the shell.  Presently available connectors having mounting elements non-integral with the elastomeric insert occasion-ally come apart under mechanical abuse, but are usually difficult to disassemble for service, and are sometimes difficult to mate. Significant advantages over prior elastomeric molded connector mounting systems are achieved by the present connector assembly in which an elastomeric molded connector insert is locked within a rigid shell.  The rigid shell which protects the insert from mechan-ical abuse and environmental conditions is adapted for mounting to panels or to other supporting surfaces.  Engagement of the ring with the shell is accomplished by radially movable retention means.  The retaining ring produces a tight, tamper proof interengagement between the shell and the insert which nevertheless may be readily released with a simple tool which is inserted through a passageway provided in the connector assembly.

Abstract: ABSTRACT               RCA 74,394 In a remote controlled television receiver, the regulator circuit of the main television receiver power supply is made responsive to a remote on/off command signal in order to turn the receiver on and off.  A deflection flyback transformer provides operating voltages to the ultor supply and other auxiliary supplies which power such load circuits as audio and vertical deflection.  A horizontal output transistor is coupled to a B+ operating voltage terminal of the main power supply through a flyback trans-former primary winding.  After initiation of the on-state of the command signal, the regulator circuit rapidly develops a B+ operating voltage.  The initially uncharged filter capacitors of the auxiliary supplies act as a low impedance shunt across the flyback transformer primary winding during the start-up interval.  To limit the horizontal output transistor collector current and power dissipated during start-up, the horizontal driver stage holds the forward base current supplied to the horizontal output transistor each deflection cycle during start-up below the steady-state value.
