Title: Method and apparatus for bagless continuous ambulatory peritoneal dialysis
Inventor: KENDELL LAMAR C
IPC: A61M39/22
Filed: 1988-03-14
Granted: 1993-04-13
Abstract: ABSTRACT         A method and apparatus for bagless continuous ambulatory peritoneal dialysis comprising a valve having first, second and third fluid ports. The first and second fluid ports are secured to first and second fluid containers, respectively, through tubing and respective first and second connector assemblies.  The third fluid port is connected through tubing to a catheter implanted in the abdominal wall of a user, also through a connector assembly.  The valve includes an actuator moveable at least between four positions, a first position in which all of the fluid ports are blocked to prevent the flow of fluid through the valve, a second position in which the second and third fluid ports are interconnected, a third position in which the first and second fluid ports are interconnected, and a fourth position in which the first and third fluid ports are interconnected.  The method employs the valve to provide bagless continuous ambulatory peri-torneal dialysis by reversing the fluid containers and the direction of movement of the valve actuator for alternate cycles.

Granted: 1992-02-25
Abstract: Abstract An apparatus and method for forming a fluid-tight seal at an aperture where a rotatable shaft passes through a barrier into a barred fluid.  A mechanical seal is mounted on the rotatable shaft.  A stationary portion of the mechanical seal is elastomerically joined to the barrier by an elastomeric joint to form a substantially fluid-tight chamber bounded by the mechanical seal, the elastomeric joint and the barrier.  The stationary portion of the mechanical seal is sealingly positioned adjacent to the rotatable portion of the mechanical seal.  the elastomeric joint absorbs relative radial and axial motion between the barrier and the mechanical seal.  The chamber is flushed with a flushing fluid.  The stationary portion of the mechanical seal is rigidly anchored to the stationary shaft drive housing.  The rotatable portion of the mechanical seal is attached to the rotatable shaft at such a distance from a stationary drive shaft housing that the resistance of the shaft to radial deflection is substantially maximum.

Abstract: ABSTRACT       A method and apparatus for controlling a bridge circuit for providing current or power to a load.  The bridge comprises two transistors including flywheel diodes and connected in series between positive and negative power supply rails for conducting current to or from the load under control of a control drive circuit.  An LC-circuit is connected between the bridge circuit and the load.  The bridge voltage (E) of the connection between the two transistors and the current (I) through the inductance of the LC-circuit are monitored and a firing pulse is supplied to one of the transistors.  When the current (I) through the inductance exceeds a present value (I'), the transistor is turned OFF, whereupon the current of the inductance continues to flow another way through the flywheel diode of the opposite semiconductor member and consequently the bridge voltage (E) changes polarity a first time to the opposite rail polarity until the magnetic energy of the inductance has been terminated resulting in a second change of polarity of the bridge voltage (E) towards the first rail polarity. The change of the polarity of the bridge voltage (E) towards the first rail polarity is detected and another firing pulse is supplied at or shortly after said change. (Fig. 3)

Title: Automatic flow control valve
Inventor: OKERBLOM CHARLES L
IPC: G05D7/00
Filed: 1988-08-18
Granted: 1992-08-04
Abstract: Abstract An automatic flow control valve according to the instant invention maintains a constant flow rate despite varying fluid pressure, and employs a dual outer and inner cup construction through which a range of flow rates can be accommodated via a change in the orientation between the outer and the inner cup.          Two modes of implementation are disclosed.  In one mode, the adjustment of the orientation between the cups to correspond to a desired flow rate is made prior to assembly and installation.  In the other mode, an external adjustment means is provided for altering the relative orientation between the outer and the inner cup at field and after assembly and installation.   In a third mode, the flow rate can be adjusted on a fully assembled valve at any time other than when said valve in installed in a process line.  Additionally, a means for adjusting the preload of a range spring balancing the cups is also provided.  In a further embodi-ment, a corrosive resistent split ring member is included as a valve component which is firmly held in a inwardly raised section of the pipe housing in which the valve is inserted and which wraps around the outer cup as an intermediate member between the outer cup and the inside surface of the pipe housing.  In this manner, corrosion of the pipe housing will not obstruct motion of the outer and inner cups.

Title: Fuel-air line-charge ordnance neutralizer
Inventor: MURRAY STEPHEN B
IPC: F41H11/14
Filed: 1988-09-23
Granted: 1992-12-15
Abstract: ABSTRACT         The invention provides a system for breaching a lane in a minefield containing pressure sensitive mines.   A mobile carrier mounts fuel,  nitrogen and water tanks,  a hose magazine and a launch rail.   A flexible hose is folded into the magazine for rapid deployment therefrom and carries a detonating cord therein.  A tow vehicle, such as a rocket, is connected to the free end of the hose so that when it is launched it will pull the hose across the minefield.   Thereafter, pressurized nitrogen is used to drive liquid fuel into the hose, followed by a slug of water between the fuel-containing section and the carrier.  Detonation of the cord creates a fuel droplets-in-air-cloud above the hose, which cloud is subsequently detonated to create a pressure wave which, in turn, detonates or neutralizes the mines along the desired lane, allowing vehicles and personnel to travel therealong.  Means are provided to space the detonating cord from the inner wall of the hose so as to prevent the formation of hot spots as the cord detonates, which hot spots could result in premature local deflagration of the fuel droplet-air cloud.

Abstract: An hydropatterning apparatus conveys a sheet of fabric through a patterning station along a machine direction on a conveyor, preferably a drum, having a support surface formed with a pattern of raised or solid areas and lowered or void areas, and has one or more manifolds of hydrojet nozzles disposed above the conveyor for directing a continuous curtain of fluid downwardly to impact on the fabric so that properties of the fabric become altered in correspondence to the pattern of the support surface.  Fabric colored with a non-colorfast dye is hydropatterned by subtractive color removal to obtain a patterned washout effect.  Alternatively, a support surface having raised or embossed areas is used to obtain a fiber displacement, lace-like effect in light fabrics.  The disclosed hydropatterning technique is particularly suitable for producing a color washout effect in indigo dyed denim.

Abstract: ABSTRACT      This invention comprises an activating means for releasing fluid from a pressurized container and a nozzle means for directing the fluid therethrough to a desired location.  The activating means comprises a lever which transmits an applied force to a flange which exerts a downward force to the top of a spout in a valve assembly used to release the contents of a pressurized container.  When force is applied to the lever, the flange rotates about a fulcrum located at a higher elevation than the point at which the flange contacts the spout.   This results in a trigger mechanism with a high degree of leverage.  The nozzle means contains a first joint for rotating a first barrel of the nozzle 360° around a first axis defined by the first barrel of the nozzle and a second joint for rotating a second barrel of the nozzle at least 180° around an axis perpendicular to the first axis. This combination results in a nozzle that can point in virtually any direction without the necessity of moving the source of the fluid directed through the nozzle.
