Abstract: The drilling motor is provided that operates pursuant to the Moineau principle for drilling deep holes or wells in the ground. A helically extending rotor is disposed in a stator having a rigid shell that is provided on the inside with an inwardly helically extending lining of elastomeric material for receiving the rotor. The shell has essentially cylindrical end sections having an inner thread for securement of connection elements of the drilling motor. The portion of the shell disposed between the end sections extends helically in conformity with the lining such that at least the lining has an essentially uniform thickness over the length of this portion, which has an outer diameter that is less than that of the end sections. Between the end sections, the shell has a thickness that is less than that of the end sections.

Title: Raster scan gaussian beam writing strategy and method for pattern generation
Inventor: DEVORE WILLIAM
IPC: H01L21/027
Filed: 1999-09-24
Abstract: A hybrid exposure strategy for pattern generation uses wide field raster scan deflection and a uniformly moving stage to expose long stripes. Periodic analog wide field magnetic scan is augmented by a high speed electrostatic retrograde scan to keep the beam essentially stationary during exposure of rectangular flash fields and/or Gaussian beams. In this manner a staircase deflection trajectory is created for the beam. The position and dose data for each flash is derived from a rasterized data format using a decoder device.

Title: Gaseous fluidization aids
Inventor: JIAO SHI-YUN
IPC: B01J8/18
Filed: 1999-08-13
Abstract: A low-molecular-weight gas is used as a fluidization aid, by adding it to th e fluidizing gas even in fairly low ratios, or in some cases by having it in much higher ratios, including up to 100 %, where it in effect is the fluidizing gas as well as a fluidization aid. The low-molecular-weight gas could be, be example, hydrogen, deuterium, tritium or preferably, helium, or  mixtures of these gases. The low-molecular-weight gas may be used with or without other fluidization aids, as desired. Although particularly useful fo r Geldart Group C particles and to a lesser extend for Geldart Group A particles, improved fluidization is achieved even for some larger particles,  whether the low-molecular-weight gas is added into the fluidization stream o r whether it is used as the sole fluidizing gas.

Title: Cyclonic evaporator
Inventor: WOODLEY PAUL STAIR
IPC: B01D19/00
Filed: 1999-09-30
Abstract: A method and apparatus for separating the components of a feed material prior to or simultaneously with at least partially vaporising one of the components is described. The apparatus comprises at least one inlet (8) for admitting the feed material (10) containing the two components to the apparatus (2) wherein a device for introducing a first movement to the feed material is located, such as, for example, an in-line swirl gen-erator (14), which imparts a swirling movement to the feed material to partially separate the components into two swirling flows. The partially separated material on emerging from the in-line swirl generator (14) is in an evaporation tube (20) in which the more volatile component is vaporised to further assist in separating the two components into a liquid component and a gaseous or vapour component. The liquid component and the vapour phase are discharged from the apparatus in two streams through the same outlet (36). Modifications of the method and apparatus include (i) having multiple evaporation tubes (20), each optionally provided with its own in-line swirl generator to facilitate better distribution and separation of the feed material, and (ii) having a reject nozzle (40) and reject conduit (42) located within the generator for allowing passage of vapour or gas through the in-line swirl generator (14) when there is an intermediate flow formed in the generator (14) and conveyed to the evaporation tube (20). The method and apparatus of this application are used as a pre-treatment in an overall separation plant.
