Abstract: APPARATUS AND METHOD FOR POSITIONING ONE PART RELATIVE TO ANOTHER PART     ABSTRACT OF THE DISCLOSURE      Disclosed is an aligning apparatus for positioning a first part with respect to a second part, which includes a lower cylindrical guide adapted to be affixed to the first part, the lower guide defining at its upper end a lower helical surface which includes half right hand and half left hand helical sur-faces.  A corresponding upper cylindrical guide is adapted to be affixed to the second part, the upper guide defining at its lower end an upper helical surface substantially identical to the lower helical surface.  The apparatus further includes a cylinder which is adapted to be affixed to the second part and a piston which is slidably mounted within the cylinder to be extendable and retractable by the selective application of fluid pressure to the cylinder.  The piston is further adapted to engage the lower guide when extended and thereby axially align the upper and lower guides.  After the guides have been axially aligned, the piston may be retracted, and the resulting contact between the upper and lower helical surfaces causes a rotational torque which rotationally aligns the first part relative to the second part.  In another embodiment, the appa-ratus is adapted to connect the first part with the second part after positioning the parts.  In the latter embodiment, the upper guide is affixed to and forms a part of the piston, and an axial alignment member is affixed to and projects from the lower guide.  The axial alignment member is adapted to engage the upper guide and thereby axially align the upper and lower guides.  Once the guides are thus axially aligned, the upper and lower helical surfaces are allowed to contact with the pis-ton extended.  The contact between the helical surfaces causes the rotational alignment of the first part with the second part.  The piston is then retracted, thereby causing respective mating elements of the first part and the second part to engage.  The force of gravity is preferably used to bring the helical surfaces together and thereby cause a rotational torque to be applied to the first part relative to the second part.

Abstract: D-21,803 FRAME SEARCH CONTROL FOR DIGITAL TRANSMISSION SYSTEM   by Ralph LeRoy Kline ABSTRACT OF THE DISCLOSURE     A frame search control circuit for a digital trans-mission system includes an eight bit preview store and a four stage counter.  At the beginning of each frame a timing device causes the eight stored bits  to be sequentially read out into a comparator for a comparison with bits from the incoming bit stream. The in-coming bits are stored in the preview store simultaneously with the read out to the comparator.  For an in-frame condition only the first comparison is important and the remaining comparisons are ignored.  Further, a count of eight is loaded into the four stage counter which limits the count to eight allowing only eight bits from the incoming bit stream to be read into the preview store, the framing bit being read in first so as to be available for comparison at the next framing interval.  For an out-of-frame condition, the timing device initiates the sequential comparison beginning with the framing interval and in this case, each comparison is important. further, a count of eight is not loaded into the four stage counter.          The counter begins counting from 1111 and, if a correct comparison occurs during any of the first eight counts, a load function is enabled.  This causes a count of eight, 1000, to be immediately loaded into the counter.  Also, for each count which is less than eight, a control signal is enabled which inhibits the framing clock for one time slot for each such count.  Thus, the position of the frame interval is shifted so as to appear in the proper time slot D-21,803 once an in-frame condition is obtained.  If a correct comparison is not obtained during the first eight counts, the control signal changes state allowing the framing clock to run and the next eight incoming bits are shifted into the preview store.  In succeeding frames the process will be repeated until an in-frame condition is obtained.

Abstract: ABSTRACT OF THE DISCLOSURE The system utilizes a heat engine which provides shaft power and heat such as a conventional diesel engine in which part of the shaft power drive a pump for fluid to be heated; for example, a cryogenic liquid.  The engine heat is used to heat and/or vaporize the cryogenic liquid in a heat exchanger.  The heat available from the engine for transfer to the liquid to be vaporized is proportional to the power level of the engine. The heat required to heat the fluid to a desired temperature is proportional to the flow rate of the cryogenic liquid.  by providing a loading on the engine which is proportional to the fluid flow rate, a sufficient amount of heat is provided to effect complete vaporization of the liquid, the amount of heat being directly propor-tional to the flow rate of the liquid.  The loading of the engine can be accomplished by a power absorbing hydraulic drive connected to the engine shaft with the hydraulic medium used to drive the cryogenic liquid pump.  A pilot valve operates a reversing valve connected to a ram cylinder for providing a reciprocating output to drive the actuating member of the fluid pump.  A surge suppression plate in-terconnecting the valves, ram cylinder, and loading means into a unitary structure.

Abstract: RCA 74,605 Abstract of the Disclosure An automatic kinescope beam current limiter for a television receiver includes a source of derived beam current representative voltage, a keyed sampling circuit for developing an output beam current control voltage on a charge storage capacitor in response to the derived voltage, and an auxiliary current path including an impedance coupled between the output capacitor and the source of derived voltage.  In a normal beam limiting control mode, the control voltage from the sampling circuit serves to modify the television signal in response to the derived voltage in a direction to limit excessive beam current.  In an abnormal control mode such as when the sampling circuit is inoperative due to disrupted keying, current is conducted via the auxiliary current path in response to the derived voltage to modify the control voltage on the capacitor with a sense and at a rate for limiting excessive beam current, to thereby preserve beam limiting capability.
