Granted: 1993-03-30
Abstract: ABSTRACT OF THE DISCLOSURE     A flexible collapsible container (10) is filled with fluid by connecting a  fluid conduit  (18)  to a tubular port  (20)  which communicates through one of the  walls  (12)  of  the  container  to  the  container interior, and rupturing a sealing diaphragm (24) that closes the bore (34) of the tubular port.  One then passes  fluid  through  the  conduit  to   fill   the container.  Thereafter,  one seals either or both the tubular port and plastic wall which carries it to the other, opposed plastic wall (14) of the container with seal  line  means  to  close  off  flow  communication between the bore of the tubular   port  and  a major portion of the container interior which contains the fluid.   The  effect  of  this   is  to  block flow communication between the bore and the fluid so that the  contents  of  the  container  remain  sealed  on disengagement of the  fluid conduit  from the tubular port.

Title: Elastomer-coated fabric products and process for producing the same
Inventor: DAVIS DELBERT A
IPC: B29C70/22
Filed: 1988-12-15
Granted: 1993-06-01
Abstract: ABSTRACT OF THE DISCLOSURE    Elastomer-coated  fabric  products  having  predetermined potential  extension  in  the  fabric's  machine direction  and processes for producing the same are provided.   The fabric product comprises a knit base fabric and an elastomeric coating layer on the base fabric, the knit base fabric being compressed in the machine direction thereof and maintained in the compressed state by means of the elastomeric coating.   The fabric is compressed in the machine direction (as by overfeeding the fabric to a tenter frame during production) so as to provide a second potential elongation, and is maintained in its compressed state by virtue of the elastomer coating thereon.  The first and second elongation potentials thus collectively establish the total potential elongation for the fabric in the machine direction.          The  cross-machine  yarns,  however,  are  chosen  for  their inextensible properties so that the fabric product will provide lateral support to end use products employing the same as a reinforcing  medium,  e.g.  tires,  power  transmission  belts, conveyor belts, and the like.

IPC: G05D7/06
Filed: 1989-02-15
Granted: 1993-09-07
Abstract: 53,887 ABSTRACT OF THE DISCLOSURE      A method and apparatus for controlling the operation of a normally open bypass valve in a steam turbine air inleakage exhaust vent pipe.  The valve is used to bypass a flowmeter connected in a bypass pipe parallel with the valve.   The flowmeter provides signals indicative of bypassed flow.  The method and apparatus compares the signals from the flowmeter to a reference  signal corresponding to a  first predetermined flow rate and generates a valve closure signal if the flow through the flowmeter is less than the predetermined flow rate.  If the valve is closed, the signals from the flowmeter are used to display the actual air inleakage exhaust rate.  If the flow exceeds a second predetermined value, a signal is generated to open the valve for bypassing the exhaust through the valve around the flowmeter. During the second mode of operation, the flowmeter indicates only approximate inleakage exhaust flow rate.  If the flow drops below the first predetermined value, the valve is again closed and the flow rate is measured by the flowmeter.

Title: High heat flux roll and press utilizing same
Inventor: MILLER RAY R
IPC: D21F3/02
Filed: 1989-03-16
Granted: 1993-04-13
Abstract: ABSTRACT OF THE DISCLOSURE The disclosure describes a drum or roll which may be heated to high operating temperatures and is particularly useful in situations where a high heat flux is required under conditions of high nip and distributed loads on the drum. It consists of a relatively thin rotating shell supported on an axially located stationary inner core. The core has a plurality of shell support bearings. These have close radial clearances with the inner surface of the shell at each location where an external nip roll would be engaged. The spaces between the shell support bearings form pressurizable chambers. These chambers can be filled with a hot pressurized fluid for supporting the shell between the supports located at the nip positions. In one application the roll would be used as the drum in a belt and drum press having light nip loads at several locations and high distributed loads applied by a tensioned belt. The fluid support system for the rotatable shell enables a very thin shell to be used. This permits the desired heat flux while still maintaining the mechanical integrity to support the applied loads. Operating temperatures of the roll could range up to 425°C with multiple nip loads typically being up to 180 - 350 kilograms per linear centimeter and 690 - 6900 kPa unit pressure, and with dis-tributed loads between the nips of up to 340 kPa. High thermal conduc-tivity materials such as copper or aluminum may be used as shell mater-ial to reduce temperature differential and thermal stress.

Granted: 1993-12-28
Abstract: ABSTRACT OF THE DISCLOSURE   The invention refers to a lifeline which is designed to lower persons down from a burning building, after evacuation through a window, distinguished by the lifeline having a length which corresponds to the mounting height of the equipment, sliding over a friction pulley with a keyway which will cause braking to occur under the weight of persons being lowered.  The friction pulley has a centred over-dimensioned axle wheel and runs between two bolts attached to the sideplates of a housing, which is fastened with a bracket to a window sill.  Under loading, the line locks the friction pulley fast against the bolts so that the line runs in the friction pulley's keyway and the line passes between two pins placed in the lower end of the two sideplates to hold the line in the keyway circumference.  At the shortest line end, when the lifeline is coiled up, a safety harness is fastened made of a suitable soft material.  The lifeline is stored in a cassette fitted with a sliding lid with line release.  By pressing the lid down a little the cassette is freed which can be thrown out of the window with the longest end of the line.  The lifeline which runs round the friction pulley can easily be hauled up to the exit position when the unloaded friction pulley runs freely back.

Title: Floatation cover
Inventor: ROBERTSON WILLIAM L
IPC: B65D88/34
Filed: 1989-04-07
Granted: 1992-09-29
Abstract: ABSTRACT OF THE DISCLOSURE           Flotation covers for large bodies of liquid, e.g. reservoirs usually consist of large sheets or panels adapted to float on the surface of the liquid.  Such covers are adapted to follow changes in liquid level.  However, in general, the problem of covering the surface of the liquid around the periphery of the cover is not addressed.  A solution to this problem involves a panel covering all but the peripheral edges of the liquid surface, cables connected to the edges of the panel and to counterweights for maintaining the panel centered on the surface, and floats for supporting the edges of the panel and the bottom edge of a skirt, which extends upwardly to the wall of the reservoir, the skirt being connected to the cables by slip rings, so that the skirt folds and unfolds as the liquid level rises and falls.

Granted: 1993-03-23
Abstract: A COST-FUNCTION DIRECTED SEARCH METHOD FOR GENERATING TESTS FOR SEQUENTIAL LOGIC CIRCUITS Abstract A method for developing a test sequence and for testing manufactured digital circuits. Test vectors are developed based on a simulation-based, directed-search approach. Specifically, front a given test vector, a next test vector is developed by altering the given test vector and determining the utility of the altered trial vector in propagating circuit fits to the primary outputs, based on a simulation of the circuit and a preselected cost function. The vector set is created through an iterative process of altering an accepted test vector to develop a next trial vector. The vector set is efficiently developed by employing one phase that treats the entire set of circuit faults as the target, followed by another phase that targets specific faults that have not been detected in the previous phase.

Title: Tamperproof, single use, disposable tattoo equipment
Inventor: PIPERATO RICHARD A
IPC: A61M37/00
Filed: 1989-06-20
Granted: 1992-05-26
Abstract: ABSTRACT OF THE DISCLOSURE A tattoo needle bar holder and needle bar assembly is fash-ioned so as to be economical to manufacture and therefore readily disposable in order to promote sanitary conditions in the tattoo industry. The needle bar holder is preferably formed from a plastic material in order to render it incapable of withstanding sterilization processes involving very high pressures and temper-atures, which would render the holder incapable of further use. The material is preferably also stained by the inks normally used in the industry, thereby serving to alert persons of any prior use. The caps which seal the assembly prior to use are prefera-bly formed to require the breakage of a frangible portion upon removal in order to prevent the reinstallation of the caps. The needle bar assembly is composed of several relatively simple components for ease of manufacture, and contains an eye and plastic or elastomer grommet at the upper end of the needle bar for precise attachment to the tattooing mechanism. The grommet is also of a material which would be damaged under conditions of extreme pressure and/or temperature, thereby rendering the needle bar assembly to which it is attached incapable of further use if sterilization is attempted.
