Granted: 1991-11-05
Abstract: Abstract of the Disclosure A pressure vessel for a backpack agricultrual sprayer is mounted within a container of the sprayer and connected to the sprayer pump so that liquid from the container is forced under pressure into the pressure vessel for a spraying discharge therefrom. Leakage of liquid past the piston of the sprayer pump is contained by a leak proof diaphragm in a diaphragm chamber which is connected by a conduit to the interior of the sprayer container. The diaphragm is connected to the piston to be operated therewith thus providing two separate but simultaneously acting pumps. The first pump is the piston pump for pressurizing the liquid for spraying discharge. The second pump is the diaphragm which forces liquid back and forth between the container and the diaphragm chamber in a high velocity stream which agitates the contents as the stream is projected into the container interior.

Title: Process and apparatus for the processing of prints carriers printed with security-paper prints
Inventor: KUEHFUSS RUNWALT
IPC: B65H39/00
Filed: 1987-06-03
Granted: 1991-07-09
Abstract: ABSTRACT     The print carriers which bear security-paper prints arranged in longitudinal and transverse rows and on which misprints are marked are numbered in such a way that all security-paper prints arranged in succession in a longi-tudinal row, but excluding misprints, receive a consecu-tive numerical sequence.  Each longitudinal row contains security-paper prints of a specific numerical series.  The print carriers are then cut into strips transversely rela-tively to the longitudinal rows.  Approximately every 100 strips are stacked, in the order in which they occur, into a strip stack    , in which all the security-paper prints arranged vertically on top of one another, if appropriate mixed with misprints, have a consecutive numerical sequence of a particular series.  The strip stacks     are cut into security-paper bundles     which are sorted according to numerical series by means of a distributor station and are fed to as many separate buffer stores as there are numerical series.  All the buffer stores are followed by stations              for separating out the misprints, stations                      for forming and banding bundles    , each with 100 security papers, and stations              for packaging each set of 10 bundles into security-paper parcels    , all these stations operating in parallel and independently of one another.

Abstract: DYNAMIC COUPLER USING TWO-MODE OPTICAL WAVEGUIDES Abstract of the Disclosure An optical mode coupling apparatus includes an optical waveguide  that  couples  an  optical  signal  from  one propagation mode of the waveguide to a second propagation mode of the waveguide.  The optical signal propagating in the waveguide has a beat length, and the coupling apparatus includes a source of perturbational light signal that  propagates   in  the  waveguide   in  two  spatial propagation modes having different propagation constants so as to have a perturbational  signal beat length.  The perturbational signal has an intensity distribution in the waveguide  that  causes  periodic  perturbations  in  the refractive indices of the waveguide in accordance with the perturbational   signal  beat   length.     The  periodic perturbations  of the refractive indices  of  the optical waveguide cause cumulative coupling of the optical signal from one propagation mode to another propagation mode. The perturbational light signal can be selectively enabled and disabled to selectively enable and disable coupling of the optical signal between the propagation modes.     UA3-985:bb/cc4

Title: Method for shaping thermoplastic fabrics
Inventor: GOTO FUMIO
IPC: D06C23/04
Filed: 1988-02-22
Granted: 1992-09-29
Abstract: ABSTRACT         A method for shaping thermoplastic fabrics such as those made of polyester or polyamide fibers into desired three dimensional configurations through a simple procedure is disclosed.  Thermoplas-tic fabrics are immersed into hot liquid metallic bath made of eutec tic metals such as lead, tin, cadmium, zinc and bismuth and formula-ted to have the eutectic point at least equal to or higher than the softening point of the thermoplastic fibers and lower than the melt-ing point of the fibers.  This metallic bath may be called "fluidic lower mold."  The thermoplastic fabrics are immersed into the fluidic lower mold by means of an upper mold or core member having desired outer configurations substantially corresponding to those of final products, for example, headrest or seat cushion.  The upper mold pushes down the fabric into the metallic bath.  Immersed fabrics receive high compressive forces and heat from the hot liquid metallic bath, and thus can easily and rapidly be shaped around the upper mold, so to speak, at a single shot.

Granted: 1993-05-25
Abstract: ABSTRACT An improved metal to metal seal packoff system for establishing a high pressure metallic barrier between adjacent surfaces of concentric tubular elements in a well head housing and casing hanger, is provided.  The packoff comprises assemblies of parts including uniquely configured metal seal elements and seal energizers therefor, which cooperate in a novel manner to produce a significantly improved seal with considerably enhanced ability to withstand unusually high fluctuations in well pressures.  The packoffs are relatively easy to assemble and are capable of installation as an assembled unit into a subsea or other remotely located wellhead without complicated procedures or other detrimental problems. The packoff seal is locked in a retracted, unenergized position while it is being run or otherwise placed in proper position in the well head and activated to expand the metal seal lips into energized contact with the opposed surfaces of the wellhead.  Such activation cannot occur until performed by the operator through use of a packoff running tool.
