Title: Fabric for airbag
Inventor: SWOBODA PETER
IPC: D03D1/02
Filed: 1992-04-14
Abstract: There is described a synthetic yarn fabric for the gas-releasing part of an airbag. The synthetic yarn is a syn-thetic high-tenacity multifilament yarn having a filament linear density of less than 4 dtex and a yarn count within the range from 250 to 550 dtex. The fabric itself is in a crepe or modified huckaback weave. In contradistinction to the conventional polyamide fabrics, it is uncoated and is preferably woven from unsized yarns. The fabric need not be calendered. It has been found that this fabric of fine-filament, high-tenacity polyester yarn, although uncoated, does meet the airbag fabric requirements such as readily preselectable air permeability, low fabric weight and low fabric thickness and also high fabric strength.

Title: Method for manufacturing a correction mask for an image intensifier tube of the proximity-focus type having an oblong cathode and anode, and also a method for correcting an image intensifier tube
Inventor: VLASBLOEM HUGO
IPC: H01J29/89
Filed: 1990-09-26
Abstract: A method is described for manufacturing a correction mask for an image intensifier tube of the proximity-focus type having an oblong cathode and anode. Such image intensifiers tend to have a non-uniform light output at the anode in response to a uniform input image at the cathode. A measurement is made of the light output distribution along at least one line at the anode under uniform illumination of the cathode, which measurement is used to manufacture a transparency for attachment on the output window of the image intensifier tube. The transparency is provided with a light absorbing line, which line absorbs more light at those positions along the length of the output window where the light output was higher. The absorbence of the light absorbing line is made proportional to the difference between the actual light output and required value light output, whereby the light output of the image intensifier tube is equalized to a required level.

Title: Interactive patient assistance and medication delivery systems that sense the physical environment
Inventor: KAUFMAN STEPHEN B
IPC: G06F19/00
Filed: 1990-09-28
Abstract: A medication delivery device measures a preselected physical parameter of a patient (step 1B) as well measures at least one preselected parameter in the patient's immediate environment that relates to the physical parameter (step 33). A control element compares the preselected physical parameter measured with the preselected environmental parameter measured. A first command signal is generated when a predetermined correlation exists between the two parameters, while a second command signal is generated when it does not. The command signal can be used to base a decision to dispense medication to the patient (step 77), or to change the patient's immediate environment (step 73).

Title: Method of Inspecting Limited Slip Differential for Vehicle
Inventor: SHIBAYAMA TAKAO
IPC: G01M13/02
Filed: 1992-09-17
Abstract: A limited slip differential which is incorporated into a differential gear for driving one wheel and the other wheel of a vehicle is inspected as follows.  One wheel and the other wheel are mounted on one roll and on another roll, respectively.  Acceleration of the vehicle is performed while the aforementioned one roll on which the aforementioned one wheel is mounted is being subjected to a force of restraining the rotation of the aforementioned one roll.  A difference in rotational speed between the aforementioned one roll and the aforementioned another roll on which the other wheel is mounted is measured during the accelerating operation.  A torque which operates on the aforementioned one roll is measured.  A limited slip differential torque which is generated by the limited slip differential is measured from the measured torque.  That standard value of the limited slip differential torque which is generated at the measured difference in rotational speed and the obtained limited slip differential torque are compared to judge whether the limited slip differential is acceptable or not.

Title: Blasting apparatus
Inventor: KIRSCHNER LAWRENCE
IPC: B24C7/00
Filed: 1991-04-04
Abstract: Conventional industrial pressure blasting apparatus (8) is modified to allow a controlled pressure on the blast pot that is greater than the pressure on the line where the media and air are mixed for conveying the mixture to the nozzle and then to the workpiece. A media control device (18), with a fixed but readily variable area, is placed between the blast pot (10) and the media/air mixing line (20) to meter the media flow and maintain the pressure differential between the blast pot and the line. This allows control of the media flow when low flow rates, below about 10 pounds per minute, are required.

IPC: C08L23/04
Filed: 1991-06-19
Abstract: Novel, unstretched synthetic papers being virtually free of mechanically produced microvoids and having a porous surface for writing and printing thereon are disclosed. The unstretched synthetic papers of the instant invention are formed typically by extruding from pellets a film or sheet material formed with a continuous olefin resin matrix containing an effective amount of a particulate filler having microvoids inherent thereto, such as a diatamaceous earth. The microvoid particulate filler is dispersed somewhat uniformely yet randomly throughout the continuous olefin resin matrix of the unstretched synthetic papers to provide non-mechanically produced microvoids in with the surfaces porous for imparting writeability and printability thereto. The novel, unstretched synthetic papers of the present invention have good receptivity and retentivity for common writing materials, such as ink, pencil lead, and paint, even though they are not mechanically stretched to form mechanically produced microvoids .
