Title: Thermoplastic molding compositions
Inventor: GEYER EUGEN J
IPC: C08L23/02
Filed: 1991-08-29
Abstract: 354-2229(8CW-5144) ABSTRACT OF THE DISCLOSURE Compositions    comprising    polyetherester    resins, polyetherimide ester resins alone or combined with polyester resins, and mixtures of any of them or of polyester resins alone with copolymers of alpha-olefins and vinyl esters of aliphatic  monocarboxylic  acids  have  improved  elastomeric character.  For example, addition of 50 and 30 parts by weight of a vinyl acetate-ethylene copolymer having a high content of units derived from vinyl acetate to a polyetherimide ester copolymer considerably improves compressibility, elasticity, low temperature impact strength,  UV light resistance and chemical resistance.  Articles shaped from such compositions show  desirably  lower  hardness,  improved  dynamic  fatigue properties,   paintability,   extrudability   and injection moldability.

Title: Single-scan time delay and integration color imaging system
Inventor: SCHLIG EUGENE S
IPC: H04N9/04
Filed: 1991-10-31
Abstract: Abstract of the Disclosure An electronic imaging system develops red, green and blue  images  of  a  document  in  a  single  pass  of  the document  through the  system.   The  system  includes  an image sensor which has three time delay and integration (TDI) sensor arrays.  Each sensor array is configured to have two optically masked rows of charge coupled devices (CCD's) for every row of CCD's that is used for imaging. The sensor arrays are arranged so that the first row of imaging CCD's on any two successive arrays are separated by a distance of an integer,  K,  times three times the height of a picture element (pel) of the image of the document that is projected onto the image sensor, plus or minus one pel height.   The  spectral  component of the image of the document that is projected onto the image sensor is changed in sequence from red,  to green,  to blue.  As the spectral component projected onto the image sensor is changed, the image of the document is scanned down the image sensor by a distance of one pel height. By this scheme,  each line of pels in the document is imaged in each of the sensor arrays in a respectively different spectral component.  A document may be imaged in all three colors in a single pass through the system without having dedicated filters for each of the separate sensor arrays.

Title: Starting aid for an electrodeless high intensity discharge lamp
Inventor: DAKIN JAMES T
IPC: F21S2/00
Filed: 1991-11-28
Abstract: LD10,087 ABSTRACT    This  electrodeless  high  intensity  discharge  lamp comprises a light-transmissive arc tube having spaced wall portions of dielectric material and a first gaseous fill within the arc tube.   An excitation coil about the arc tube is energizable with RF current effective to develop a toroidal arc discharge in the first gaseous fill upon a dielectric breakdown of the fill.  A starting container is joined to the arc tube and has an end wall constituted by one of said arc-tube wall portions.  A second gaseous fill within the starting container has a dielectric strength lower than that of the first gaseous fill.  For initiating said  toroidal  arc  discharge,  we  provide  means  for producing  a  dielectric  breakdown  of  the  gaseous  fill within  the  starting  container  that  develops  into  an, electric discharge that changes the potential at said end wall in such a manner as to cause a dielectric breakdown of said first gaseous fill.

Abstract: ABSTRACT OF THE DISCLOSURE          A pressure washer for delivering a liquid under high pressure has an inlet conduit connected to a liquid supply and an outlet conduit connected to a spray nozzle which can be operated to control the delivery of liquid through the nozzle.  A bypass conduit enables recirculation of the liquid from the outlet conduit to the inlet conduit.

The shuttle includes an axial passage from its inlet to its outlet side which passage has a narrowed jet outlet such that, when the liquid flows through the spray nozzle and the outlet conduit, the pressure drop across the shuttle moves the shuttle to the first position, while when the flow out the spray nozzle is stopped or significantly blocked, pressure on the side of the shuttle facing the spray nozzle rises to the level at the inlet side of the shuttle, which moves the shuttle to unblock the bypass conduit.  A spring aids the return motion of the shuttle to the second position.            #5544
