Abstract: ABSTRACT OF THE DISCLOSURE:         A marine riser system for offshore well installations having a plurality of satellite subsea wells wherein production flow is conducted to a composite manifold structure on the sea floor, is raised to a floating platform for processing and processed production fluid is then returned to the manifold for transfer to storage or other facility.  A riser pipe system which extends between the manifold structure at the sea floor and a floating platform wherein unprocessed production fluid is trans-ported under high pressure in the riser system by a plurality of satellite or perimeter riser pipes which are arranged in a circle about a central riser pipe and which are separately and independently supported and maintained.  Processed production fluid is conducted under low pressure through the central riser pipe at the center of the arrangement of satellite pipes, the central riser pipe providing a main structural member for the riser system.  A marine riser pipe system having an upper riser pipe portion including central and satellite riser sections supported and carried by the floating platform and a lower riser pipe portion and buoyant structure associated therewith which include corresponding riser sections and which is capable of independently supporting itself in water when separated from the upper riser portion.  A guiding and connecting assembly provides quick connecting and disconnecting of the upper riser portion to the buoyand structure, the lower riser portion with the buoyant structure being capable of standing vertically by itself.  The manifold includes a releasable manifold section for maintenance and repair.  A control system is provided at the manifold structure for actuation and monitoring of equipment installed on the manifold structure and on satellite wells.          The control system is remotely controlled from the platform or vessel.

Abstract: ABSTRACT     A terminal applicator for crimping closed barrel terminals in strip form onto wires has a reciprocable ram assembly, crimping dies on the ram assembly an anvil for supporting a terminal during crimping, and terminal strip feeding and severing means, the feeding means being for feeding the terminal strip towards the crimping site.  The anvil is normally in a retracted position and the strip is fed to position the leading terminal of the strip on the anvil when the anvil is in its retracted position.  Thereafter, the leading terminal is severed from the strip and the anvil is moved to an extended position in which it is at the crimping site.          During such movement, a wire held at the crimping site is located in the terminal and upon movement of the dies towards the anvil, the terminal is crimped onto the wire.

Abstract: METALLIZED FILM CAPACITORS            Abstract of the Disclosure The present invention provides a product which has all of the many advantages of pleated, wound, electrical capacitors and also has the added advantage that it may be manufactured with commercially available metallized die-lectric materials.  A further advantage of the present invention is that the same basic starting materials may be used to manufacture capacitors that have a number of different pleating combinations.  Thus, the invention provides for an electrical capacitor segment which comprises a dielectric layer having a center line, a first metallized electrode layer applied to one side of the dielectric layer so that an unmetallized margin ex-tends along each edge of a pair of parallel edges of the di-electric layer, and a second metallized electrode layer applied to the other side of the dielectric layer so that an unmetallized area is located adjacent the second metallized electrode layer.          The dielectric layer is pleated once along the unmetallized areas off of the center line so that one edge of the margin containing edges extends beyond the other of the edges along the same end of the capacitor segment and metallized spray material in contact with the second electrode layer.

Abstract: ABSTRACT OF THE DISCLOSURE         Method and apparatus for detection of acoustic signals whereby errors due to "noise", "waveform stretch" and "cycle skipping" may be minimized.  Detection of corresponding sequential half-cycle arrivals of each acoustic signal wave from transmitter at two spaced receivers activates zero crossing detectors to provide times of zero crossings A' and A in first half-cycles of waves from respective receivers and of corresponding zero crossings B' and B of succeeding half-cycles of waves from respective receivers.  Difference of A'-A is used as most accurate indication of travel time if proved valid by tests such as evaluation against a predetermined reference time.  Otherwise difference of B'-B may be used instead.  Alternatively, B'-B may be subjected to similar tests for validity before using and, if found invalid, discarded in favor of the last previously used or recorded valid time difference.

Water color painting paper, when wet, is place over the flat too surfaced structure and extended beyond the perimeter grooves. Thereafter the perimeter wedges are pressed into the perimeter grooves carrying the wet water color paper edges into the grooves, thereby snugly fitting the water color paper to the flat surface of the artists' water color paper stretcher and holder. Other features of the overall structure of the artists' water color paper stretcher and holder include, in various embodiments: a selectively reinforcing ribbed bottom with the ribs formed to provide a storage space for painting supplies having a cover; in addition a rearwardly projecting portion of the board such as the rim forms a water tray for soaking the watercolor paper prior to stretching; and after a picture is completed a picture frame is attached by inserting projec-tions on the frame into slots in the wedges and thereafter the artists' water color paper stretcher and holder continues on in service as a display structure.

Abstract: ABSTRACT      A method for the improved reproduction of edges associated with sharp changes in tone density during the engraving of screened printing forms with an engraving tool.  The engraving tool is controlled by an engraving signal obtained from superposition of an image signal and a screening signal.  The image signal is derived from scanning an original with a resolution which is twice as large in the scanning direction as that of the printing screen.  Based on the higher resolution the image signal is digitalized into principal image values and additional intermediate image values.  If a sharp change in the density defined as an edge occurs in the original a principal image value and the associated intermediate image values are combined into one memory word after the image values have been recoded into values of shorter word lengths and intermediately stored.  If no edge is present in the original only the principal image values are intermediately stored as memory words.  The combined memory words are separated into the principal image values and the intermediate image values when read out of the memory.  The principal image values are superimposed onto the screening signal at the instants of periodically recurrent amplitude values of the screening signal, when the engraving tool cuts the cups and the associated intermediate image values are superimposed before said instants.  Thus, the engraving information for each cup consists of two image values, whereby the cups for a sharp change in tone density are shifted relatively to the printing screen toward a higher density level so as to accomplish improved reproduction of the edges.  Storing the image values as described allows the capacity of the memory to remain constant although a bigger number of image values are processed.

Abstract: A B S T R A C T      Apparatus and process for isotopically selective multi-step photoionization in which the final or ionizing step is tuned to produce a specific transition to an excited state above ionization for which the ionization cross-section is substantially greater than for ionization transitions in general.  The autoionization transition to an ionized state is typically made from a highly excited bound state which is reached in one or two isotopically selective energy jumps from the ground state or other low-lying levels.  The isotope shift for the ionization transition is typically small compared to the bandwidth of the ionization transition and relatively broad band photoionization radiation covering the entire absorption line can be employed.  Broad band radiation is more economic and is preferable for use whereever possible. A technique is also shown for identifying the ionization transitions of augmented cross-section.
