Title: Free flow prevention system for infusion pump
Inventor: DODGE LARRY H
IPC: A61M5/168
Filed: 1990-09-17
Granted: 2002-11-12
Abstract: A free flow prevention system for preventing free flow of fluid through IV tubing (12) when the tubing (12) is disconnected from an infusion pump (10). A flexible clamp (20, 20A) is provided having a pair of clamping arms (24, 24A), which define a variable width slot (26, 26A) for receiving the IV tubing (12). The IV tubing (12) may be moved along the slot (26, 26A) between a first position (28) (Figure 4) wherein the width of the slot (26, 26A) is sufficient to permit the clamp (20, 20A) to be positioned longitudinally along the IV tubing (12), and a second position (30) wherein the width of the slot (26, 26A) is normally less than the width of the slot (26, 26A) at the first position (28). The clamping arms (24, 24A) are resiliently biased to a closed position (Figure 2) wherein the IV tubing (12) is squeezed when in its second position (30) to close the lumen of the tubing (12) to prevent fluid flow. A clamp-receiving passageway (18, 188) and clamp-opening wedge (22) are provided on the infusion pump (10). The clamp-opening wedge (22) is movable relative to a clamp (20, 20A) received in the passageway (18, 18B) to an operating position (Figure 3), wherein the wedge (22) moves the arms (24, 24A) of the flexible clamp (20, 20A) against their bias to an open position (Figure 3) wherein the lumen of the IV tubing (12) is allowed to open to permit fluid flow during operation of the pump (10). 4:1.22

Title: Load weighing apparatus
Inventor: TREMBLAY REMY
IPC: G01G19/12
Filed: 1992-04-14
Granted: 1995-10-24
Abstract: A weighing apparatus is put forward for weighing a load carried by a load support provided with front and rear wheel assemblies each having at least one member which deforms as a result of the load. The apparatus comprises a plurality of strain  transducers  to  be  affixed  respectively  to  the members.  Each of the transducers includes a pair of spaced apart brackets to be fixedly secured to the corresponding member such that their upper ends come closer to one another when the corresponding member is deformed, and an elongated load cell having opposite ends attached respectively to the upper ends of the brackets. The load cell is provided with strain sensing elements for producing an electrical strain signal indicative of a strain variation substantially along a longitudinal axis of the load cell.  The apparatus also comprises a processing unit having inputs for receiving the strain signals of each of the strain sensing elements, a microcontroller for processing signals  derived from the strain signals and determining thereof the load and parts of the load supported by each of the wheel assemblies, and a display unit connected to the microcontroller for displaying the determined load measures.   Each of the load cells is initially subjected to a predetermined longitudinal strain when the load support is empty. When the load support is loaded, the members deform as a result of the load, bringing closer the upper ends of the pairs of brackets to one another, thereby reducing the longitudinal strain in the corresponding load cells such that the processing unit can determine and display the load and the parts of the load supported by each of the wheel assemblies.

Title: Multiple component spray gun
Inventor: MARTIN OLIN H
IPC: B05B7/04
Filed: 1992-12-08
Granted: 1999-07-27
Abstract: A multiple component spray gun for spraying plural components is claimed useful in applications involving polyurethane foams, elastomeric coatings, paints, thermosetting resin formulations, and the like.  The ejected components are atomized under high or low pressure via a novel multiple mixing action.  The gun design allows for an exchange of the mixing chamber components without the need to dismantle the gun body.  The concept of the spray gun involves a gun body and a nozzle, a rotatable ball passage valve including a ball with internal porting in a general Y-configuration with two opposing inlet passages and a cylindrical outlet bore with the ball positioned in a totally enclosed resilient resinous packing material.  The preferred packing material if formed from polytetrafluoroethylene commonly referred to under the trademark Teflon.  The A and B components are communicated across the passages of the Y-configuration prior  to the novel multiple mixing action and material back flow is virtually eliminated.  An air purge flow through the ball and nozzle is provided when spraying is completed.  The ball valve is rotated by means of a double acting pneumatic cylinder and both the air cylinder and ball reciprocate and rotate through an appropriate linkage;

Abstract: ABSTRACT OF THE DISCLOSURE         A sensor-activated, battery-powered toilet room flush valve has a body with an inlet and an outlet. There is a valve seat in the body and a diaphragm which closes upon the seat to control flow between the inlet and the outlet.  A cover mounted on the body defines a pressure chamber with the diaphragm and there are a sensor, solenoid and battery mounted on the cover and connected for operation of the flush valve.  There is a passage in the cover connecting the pressure chamber and the outlet.       Operation of the solenoid opens the passage to relieve pressure in the chamber to the outlet whereby the diaphragm moves off its seat to open communication between the inlet and outlet.  A stop is positioned within the chamber and attached to the diaphragm to limit its movement toward the cover, which in turn controls the volume of water passing through the flush valve prior to closure of the diaphragm upon its valve seat.  The stop is adjustable from the outlet side of the valve.

Granted: 1998-06-23
Abstract: This invention describes the design and method of installation of wild animal highway warning reflectors. The reflector consists of a transparent plate having a flat light entrance surface and a backside reflection surface from which the reflected light is dispersed. The rear surface is comprised of many reflecting toric surfaces arranged vertically and horizontally side-by-side. The new design of the toric surfaces and the unique method of installing the reflectors provide complete reflected light coverage for all variations of roadside terrain to warn wild animals that wish to cross a highway at night. To an animal each reflector glitters with colored light. As a vehicle passes, animals see an unnatural, sequence of lights coming from a plurality of reflectors located along both sides of the highway. Installation of these warning reflectors adjacent to highways where wild animals frequently cross has led to a considerable reduction of the number of accidents.

Abstract: A rider roll system for exerting an even nip load force along the surface of a roll of paper (24, 324) being wound from a continuous on-coming web (W) in a winder comprises a plurality of rider roll wheel elements (30a, 30b, 30c,... 330), each of which is connected to a common source (76, 376) of hydraulic pressure to provide the same rolling nip force against the wound paper roll (24, 324). The rider roll wheel elements (30a, 30b, 30c,... 330) are mounted to a beam (22, 322) which is translationally movable above the wound paper roll (24, 324). The beam (22, 322) and individual rider roll wheel elements (30a, 30b, 30c,... 330) are moved upwardly as a function of the increase in the diameter of the wound paper roll (24, 324). The relationship of the beam (22, 322) movement relative to the diameter of the wound paper roll (24, 324) is controlled by a programmable logic controller (84, 384). The individual wheel elements (30a, 30b, 30c,... 330 ) are loaded against a counter-balance force (52a, 52b, 52c,... 352) so as to provide equal, but cushioned, nip force against the surface of the wound paper roll (24, 324) at short intervals along its length. The magnitude of the evenly applied nip load force i s also controlled as a function of the wound paper roll (24, 324) diameter.

Granted: 1998-02-24
Abstract: If an access code specifying an interexchange carrier (IXC) (30) is entered by a caller (11, 12), the switch of the LEC (21, 22) routing such a call to the specified IXC (30) is arranged to transmit to the IXC (30) an indication that an access code was entered. The indication may be transmitted as a signaling system 7 (SS7) message, or a portion thereof. The LEC (20) may also provide an indication  that the carrier whose access code was entered was not the IXC carrier (30) to which the calling telephone line was PIC'd. Advantageously, using the transmitted indication, an IXC (30) can determine the number of instances in a predetermined time period that calls were placed using its access code, thereby verifying the effectiveness of its advertisements for use of the access code.
