Inventor: ALTHAUS WOLFGANG
IPC: C08J7/04
Filed: 1988-05-04
Granted: 1994-05-03
Abstract: Abstract The present invention relates to a process for forming and applying a hydrophilic coating that is extremely slippery when wet to a molded plastic or metal part, in particular a razor or a razor-blade unit, in which a solution that contains a water-soluble polymer, in particular polyvinylpyrrolidon, is applied to the molded part and there hardened, as well as the razor that is of plastic such as polystyrene or ABS or metal, this being provided with a device that increases its gliding ability.  The invention also proposes that the solution that is applied to the molded part consist of the water-soluble polymer, in particular poly-N-vinylpyrrolidon or a copolymer thereof, one or a plurality of radically polymerisable vinyl monomers, and a photoinitiator that decomposes into radicals when irradiated, and wherein the solution that is applied is hardened by exposure to ultraviolet radiation.

Title: Spray pistol using electro-kinetic charging of powder  material
Inventor: BAUCH HELMUT
IPC: B05B5/047
Filed: 1988-10-26
Granted: 1995-07-04
Abstract: A   spray   gun   with   electrokinetic   charging   of powdered material for the purpose   of   electrostatically coating workpieces with a powder coating.   As the  powder flows pneumatically through a channel of insulation material in the   form of an annular gap, the plastic powder to be applied is charged by superimposition   of   triboelectric effects   with   ionization   processes initiated by these effects at a passive ionizer electrode,  and completed by friction  against a semiconductive insert within the annular gap.   Thus, the effective   area   of   the   electrostatic induction ionizer is expanded, the charge  on the powder is increased  and  spark-like sliding discharges  in the  flow channels  as  well  as  dielectric breakdowns of the channel wall are prevented.

Title: Easily upgradable video memory system and method
Inventor: FURLONG THOMAS C
IPC: G06T1/60
Filed: 1989-06-30
Granted: 1993-03-09
Abstract: ABSTRACT            A video memory system is disclosed in which the memory module used to store video data also generates a selection signal that indicates whether the module is a monochrome or color memory module.  Memory control logic generates a pixel clock which governs the rate at which pixels of data are output to a monitor, and a load clock which determines the rate at which data is read from the memory module.  The load clock is generated at a first rate when the selection signal denotes a monochrome memory module, and at a second, faster rate when the  selection  signal  denotes a  color memory module.  A shift register receives video data from the video memory module at the rate of the load clock, and outputs that data at the pixel clock rate.   The shift register outputs a plurality of bits of the video data in parallel to a video signal generator, which converts the received data into a video signal.   To upgrade the video memory system in the preferred embodiment from a monochrome system to a color system,  a monochrome memory module is replaced with a color memory module.   Alternatively,  an upgrade can be effected by adding memory to the memory module  and  changing  the  mode  selection  signal  from monochrome to color mode.
