Title: Apparatus and method for a combination valve
Inventor: PETERSON GERALD H
IPC: A61M39/00
Filed: 1991-12-12
Granted: 1994-11-01
Abstract: A combination valve in a side port adapter prevents back flow through the side port and through a main channel has an adapter with a main channel along an axis thereof. The adapter has a side port that intersects with the main channel for flow therethrough.  A resilient member with a passage therethrough has therein a check  valve  located normal  to the  axis  and across  the passage.   The check valve opens with flow along the axis in a direction and closes to flow in an opposite direction.   The resilient member normally closes the intersection until the member deflects when fluid pressure within the side port exceeds its  resiliency.   The check  valve  is  a  web  across  the passage with  a  slit that  is normally closed.   The web shape is a duck bill.  The main channel has an inlet and an outlet positioned along the axis.   The outlet can be connected for fluid tight communication to a catheter or other  fluid  line.   The  inlet  is  in fluid communication with a fluid supply  to  provide  flow  through  the main channel to the outlet.  The resilient member and the main channel have  a  cylindrical  shape  of  a  circular  cross section.  The resilient member has an edge at a distal end thereof.  The adapter has an annular shoulder within the main channel  distal  along the axis and relative to the side port to locate the edge.  A method has the steps of providing an adapter with a main channel and a side port, placing a resilient member having a passage therethrough in the main channel to prevent flow from the main channel to the side port and providing a duck bill check valve in the passage to permit flow through the main channel in one direction and prevent flow in the opposite direction.  The valve and adapter are packed and sterilized.

Title: Fibre-optic sagnac interferometer with digital phase modulation for measuring a rate of rotation
Inventor: SPAHLINGER GUENTER
IPC: G01P3/68
Filed: 1992-01-08
Granted: 2001-01-02
Abstract: The subject of the invention is a fibre-optic rate of rotation sensor in open loop configuration, in which sensor bias errors which arise on account of coupling in of disturbing signals into the input of a demodulator (SYNCD) are suppressed by the use of a demodulation signal which is statistically independent of all signal sources which may be considered as a cause of           ~ disturbing signals. To this end, a modulation signal generator (MG) is provided, which includes a random number generator from which two signals (b0, b1) are derived on the one hand for a statiscally alternating bias for the activation of optimal working points with positive or negative gradient on the interferometer characteristic and an appropriately matched demodulation signal (d) is derived on the other hand, which demodulation signal, after transit time correction (T0), acts upon the synchronous input of the synchronous demodulator (SYNCD).

Title: Bidirectional gasket
Inventor: WESTHOFF JAMES A
IPC: E04D13/147
Filed: 1992-02-06
Granted: 2003-07-08
Abstract: A mouldable gasket is provided herein for resiliently supporting a conduit in an opening within a wall and watertightly sealing the space between the wall and the conduit, the gasket having a central axis which intersects a symmetry centreline. The gasket includes an outer annular anchoring portion, so that a symmetry centreline passes through the anchoring portion which is symmetrical about the centreline. The centreline is substantially-perpendicular to the central axis of the gasket. The gasket further includes an annular joining portion having a tapered cross-section extending radially-inwardly from, and integral with, the anchoring portion so that its longitudinal axis is aligned with, and is symmetrical about, the symmetry centreline. The end of the taper is joined to the anchoring portion and has a dimension which is less than that of an end of the taper which is closer to the central axis of the gasket. The gasket further includes an annular skirt portion having an outer end joined to, and integral with, the tapered joining portion, the annular skirt portion having an outer annular portion which is symmetrical to the centreline and having a second inner portion which is aligned diagonally relative to the centreline.  The annular skirt portion is provided with an anti-balloon portion, which is configured to limit the expansion of the gasket due to water pressure which may be applied thereto while at the same time facilitating the flexibility of the skirt. The skirt portion terminates in an enlarged annular-shaped O-ring portion defining an annular central opening in the gasket for receiving the conduit therethrough. Prior to insertion of the conduit, the length of the skirt measured between the tapered portion and the O-ring portion is greater than the distance between the O-ring portion and the tapered portion measured along the symmetry centreline. This enables the skirt to assume either one of two "over-centre"  positions on opposite sides of the symmetry centreline. The O-ring portion is of a size which is configured to embrace and engage an outer periphery of the conduit extending therethrough. This enables the gasket to be moved to either of the two "over-centre" positions by movement of the conduit which is embraced, and engaged, by the O-ring portion.

Granted: 1999-01-05
Abstract: An arrangement and method for processing signals from infrared microwave and/or ultrasonic intrusion detectors is disclosed which allows the signal to be processed at different amplitude levels to recognize different signal characteristics.  This capability to analyse the signal at different values allows further customizing of the system for particular applications and provides information useful in recognizing and dealing with unwanted signal changes typical of the environment which can effect the reliability of the alarm criteria and/or a trouble condition criteria.  An assessment of the environment in a preferred aspect allows customizing of the alarm criteria to take into account the operating environment of the particular sensor or sensors.  The system also accommodates increasing the effect on certain portions of the signal when considering the net overall effect of the signal.  This results in more signal information being available to assess possible conditions which could lead or contribute to the generation of false alarms.

Abstract: A method of forming an elongated box shape tubular frame member from a round tube includes the steps of:  providing a lower die member having a cavity submerged substantially below the top surface of the lower die and having a cavity width equal to the width of the desired box shape frame member and less than the diameter of the tube.  The lower die has an entry opening which opens to the top surface of the die and is defined by angularly disposed funnel walls which converge to intersect with the cavity.  The round tubular blank is placed onto the lower die so that the blank rests on the angularly disposed funnel walls above the cavity.  The upper die is lowered onto the lower die and has a lid wall which forces the tubular blank downwardly into the cavity while the angularly disposed funnel walls guide the blank to collapse in a manner preventing pinching of the blank between the upper and lower dies.  The application of internal hydraulic pressure then expands the collapsed tube outwardly to the shape defined by the cavity of the lower die and the lid wall of the upper die.  The lower die preferably includes rounded corners at the intersection of side walls and a bottom wall to provide rounded corners on the box shape tubular frame member.  However, the edge surfaces of the lid wall of the upper die are rounded in the reverse direction away from the side walls of the lower cavity for ease of die manufacture, so that the rounded corners of the box shape tubular frame member are provided by controlling the magnitude of internal hydraulic pressure to a level sufficient to properly expand the tube against the side walls, the bottom wall, the lid wall, and the lower corners, while not so great as to force the upper corners fully into the reverse rounded upper corners of the die cavity.

Abstract: Ideal household cleaning compositions should form a relatively stable foam on application to a surface and rapidly defoam when rinsed from the surface. The present invention subsists in an aqueous cleaning composition comprising: (a) a surfactant system comprising an anionic surfactant other than an alkali metal salt of a fatty acid, (b) C10-C18 monocarboxylic fatty acid, (c) a semi-polar solvent, (d) a polycarboxylic acid, and (e) a base, said composition having a pH of less than 6. It is believed that the C10-18 fatty acids have a foam boosting effect which improves 'cling' of the foam to sloping or vertical surfaces. When the compositions are diluted during rinsing the fatty acid and the solvent form an antifoam system which defoams the composition.
