Title: Arc source macroparticle filter
Inventor: MARTIN PHILIP J
IPC: H01J37/32
Filed: 1992-03-25
Abstract: An arc source macroparticle filter (1) includes a circular cathode (2) for emitting particles and an extended cylindrical anode (3) adjacent to and co-axial with the cathode for accelerating the emitted particles. Torroids (4) generate a magnetic field to define a continuous non-linear plasma duct (5) for directing charged particles and separating therefrom undesirable larger particles.  The duct is minimally non-linear to permit high rates of charged particle transmission. Arc source filter (1) allows heating and/or the deposition of a variety of surface coatings to a workpiece (8). Also claimed is a method of producing vanadium dioxide.

Title: Process for compressing video images
Inventor: LUHN ACHIM
IPC: H04N19/90
Filed: 1992-03-10
Abstract: Abstract of the disclosure Images are approximated by invariant densities of stochastic processes,  e.g. by so-called fractals. The parameters of those stochastic processes whose invariant densities approximate the images to be compressed in the sense of a quality criterion to an optimal extent give a compressed representation of this image. These optimal stochastic processes are found with the aid of a sto-chastic optimization process, preferably with the aid of a genetic optimization process. The genetic optimization process makes use, in this case, inter alia of mutation, crossover and exchange of genes for the alteration of the genetic  information.  With  the  aid  of  the  process, extremely  high  data  compression  factors,  typically between 1000 and 10000, are attainable. The process is suitable both for the data compression of still images and also for the compression of images derived from moving image sequences.

Title: Collimated deposition apparatus
Inventor: ACTOR GERI M
IPC: H01L21/31
Filed: 1993-12-15
Abstract: COLLIMATED DEPOSITION APPARATUS               ABSTRACT OF THE DISCLOSURE Sputtering apparatus using a collimating filter to limit the angles at which sputtered particles will reach the surface of the substrate or workpiece being processed  is shown.  The sputtering apparatus relies on a combination of a planar sputter source larger in size than the workpiece and having highly uniform emission characteristics across the much of its surface, including its center; a collimating filter; and low operating pressure to avoid scattering of sputtered atoms after they have passed through the collimation filter.  In the preferred embodiment, the collimation filter is made from a material which has substantially the same thermal coefficient of expansion as the film which is deposited on the substrate.  In one specific embodiment, a titanium collimation filter is used when the sputtering system is used to deposit filmy of titanium, titanium nitride or titanium/tungston alloy.

Title: Sterile filling system
Inventor: KRUGER ROBERT J
IPC: A61J1/20
Filed: 1994-07-18
Abstract: ABSTRACT OF THE INVENTION          The present invention is directed to a method for the on-line sterile filling of a container with a sterile solution from a filling nozzle in a filling head. A container having an open end and a hollow body portion for receiving the sterile solution is provided. The container also includes an access passageway tube having first and second ends and a pierceable septum sealing the passageway at an intermediate position within the tube. The first open end of the access passageway tube is sealed in the open end of the container so as to close the hollow body portion of the container, which is then sterilized. Later, before on line filling, the second end of the access passageway tube is isolated from the surrounding environment by axially advancing and sealably seating the filling head at the second end of the access passageway tube. The isolated end of the access passageway tube is then sterilized for a time period sufficient to reduce the viable micro-organism population present to a predetermined level. Then a filling nozzle is advanced from the filling head through the isolated and sterilized end of the passageway tube and pierces the septum of the tube. After the sterilized hollow body portion is filled with the sterile solution, the access passageway is sealed between the hollow body portion and the filling nozzle.
