Title: A roller blind drive, more particularly for shade producing means
Inventor: SCHANZ HANS
IPC: E06B9/174
Filed: 1997-04-25
Abstract: A roller blind drive comprising a roller blind member running along an oblique area to be shaded and a motor-driven and rotatably mounted winding shaft onto and from which the roller blind member may be wound and unwound.  The winding shaft is mounted in a sliding manner at each end in respective guide tracks, which in the assembled state extend obliquely downward.  The displacement of the winding shaft due to gravity in a downward direction is limited by a guide shoe element arrangement, the roller blind member unwound from the winding shaft being guided along such guide shoe element arrangement toward the oblique area.  Owing to the gravity-related displacement of the winding shaft same will at all times have the respectively wound up coil of the roller blind member in engagement with the said guide shoe element arrangement so that during unwinding the roller blind member will be unwound along such guide shoe element arrangement and thrust outward, high thrusts being able to be produced, which render possible extremely small angles of slope of down to essentially 5°.  The roller blind drive is consequently particularly well suited for shading purposes

Patent CA-2216973-A1 (CA)
Title: Wire mesh filter
Inventor: VOLL BENN ARILD
IPC: B01D29/15
Filed: 1996-03-25
Abstract: A filter is provided which combines a woven wire mesh (14) over a supporting body. The supporting body is typically a metal perforated tube which provides fluid communication between the well bore and the production equipment string. The woven wire mesh (14) acts as a filter to prevent the influx of sand particles (30), provides openings oriented at various angles relative to its surface, so that some area is available for fluid entry even when particulate matter is lodged on the surface above an opening, provides interior channels that allow fluid to travel from one location on the mesh surface to another location over an opening into the supporting body, and does not provide "straight-through" openings, thus forcing the fluid to make multiple turns (28) to pass through the mesh, thereby dissipating the fluid's energy and increases the mesh's erosion resistance. When particulate matter accumulates on the mesh's surface, the resulting particle cake remains porous, heightening the filter's resistance to plugging.

IPC: A61K8/00
Filed: 1998-03-04
Abstract: A method is provided for obtaining a customized skin foundation productto cover human skin imperfections. The steps include spectrophometrically measuring a customer's normal skin to obtain normal skin coloration values of lightness, redness and yellowness respectively denoted as L, a and b units. Thereafter the normal skin coloration values are converted through calculation to a modified value determined by a set program correcting L, a and b values. Based on the modified value the next step is formulating a facial foundation having color pursuant to the modified value. Adjustments are provided for redness and yellowness according to a set of schedules determined by the b/a ratio. Normally the measurement and skin imperfection determination are performed by a licensed dermatologist. Formulation and adjustment is conducted at a site remote from the dermatologist office or place where the customer is measured and evaluated. Most preferred is the use of a formulation machine at the remote location to convert instructions received about a customer's modified formulation to dose and blend a series of cosmetic chemical compositions containing various monochromatic colors and skin benefit agents. The optimal formula dosed from the machine is packaged and then shipped to the customer.

Patent CA-2233529-A1 (CA)
Inventor: CAVAGNA CARLO
IPC: F17C13/02
Filed: 1998-03-30
Abstract: A mechanical device for checking the level to which cylinders and the like are filled with liquid gases, comprising a feeder pipe anchored to the cutoff valve unit of the cylinder. At the lower end of the pipe there are provided openings which are connected to the inside of the cylinder and in a front region there is provided a closure membrane made of flexible material and centrally provided with at least one through hole. The membrane is peripherally locked between the rim of the end of the tubular element and a hollow body which is anchored coaxially to the feeder and is provided, in an upward region, with a cavity which allows the membrane to deform correspondingly in order to directly connect the free end of the tubular feeder body to the lateral openings thereof. The hollow body has a cavity which is coaxial to the hole of the membrane and leads into a chamber in which there is provided a shutter body movable axially by means of a cam which is associated with a floating device. In this way, during the filling of the cylinder, the membrane is allowed to deform under the pressure of the gas being fed, making it flow out into the cylinder and, in small amounts, through the holes of the membrane and of the cavity of the hollow body. In the same way, once the level has been reached, the floater is allowed to arrange the cam so that the shutter can close the end of the hollow body, so as to allow the membrane to move to a stable closure position on the end of the feed pipe by means of the counterpressure generated by the gas that acts on different areas of the two opposite sides of the membrane.

Title: Adjustable slit and method for varying line width
Inventor: MCCULLOUGH ANDREW W
IPC: H01L21/027
Filed: 1998-03-30
Abstract: Blades pivotally attached together linked to push rods and inserted into an illumination energy or flux. The blades extend longitudinally along the length of a rectangular illumination field or slit used to image a reticle onto a photosensitive substrate. The push rods are coupled to a flexure or link pivotally connected to each end of a substantially rectangular blade. The corners of the rectangular blades have a radius providing a smooth transition between blades. A frame holds the push rods in place as the blades are moved into and out of the illumination energy or flux. The push rods may be adjusted by a screw or other equivalent devices or methods. The lateral or sideways forces resulting from the movement of the blades is compensated for by the flexures or links resulting in less stress being placed on the blades. Slots placed at pivot points in the blades may also be used to facilitate movement of the blades.          The illumination energy of the rectangular illumination field or slot is adjusted to provide a uniform illumination energy. Also included is a method of adjusting the device to provide a predetermined exposure dose along the length of the illumination field as a function of line width. Different feature types may be imaged separately to optimize control over line width variation.     This is particularly advantageous in a scanning lithography system used in the manufacture of semiconductors.
