Patent CA-2113845-A1 (CA)
Title: Control system for filling tanks with saturated liquids
Inventor: FARKAS EDWARD J
IPC: F17C5/02
Filed: 1994-01-20
Abstract: The invention described in the patent is an automatic control system which provides monitoring, supervision, and control of the process of filling of a tank or container with a liquid, where at the temperature of operation the vapour pressure of the liquid is at or above atmospheric pressure. The invention provides an improved method of carrying out the process of filling of tanks with liquids such as ammonia, chlorine, propane, liquefied petroleum gas or any other liquid with high vapour pressure at the temperature of operation. The main advantage provided by the apparatus and method of the present invention is that there is offered an improved method for automatically stopping the filling process at the correct point, so as to avoid a possibly hazardous overfilled condition. Some of the methods currently  in use require a mechanical valve which senses liquid level in the tank and is supposed to dose so as to stop flow to the tank when the liquid has reached the maximum allowable level. The mechanical valve may malfunction and allow overfilling of the tank, and the fact that the valve is malfunctioning  may not be readily apparent. The improved apparatus and method of the present invention do not require a mechanical valve of the type described above. Further there is a self-checking and self-monitoring capability so that users of the apparatus and method are warned of any malfunction.

Title: No loss fueling system for natural gas powered vehicles
Inventor: GUSTAFSON KEITH
IPC: F23K5/00
Filed: 1994-03-02
Abstract: The fueling station consists of a vacuum insulated storage vessel for storing a large quantity of LNG at low pressure. The LNG is delivered to one of two relatively small volume fuel conditioning tanks where the pressure and temperature of the LNG can be raised or lowered as dictated by the needs of the system. The pressure and temperature in the fuel conditioning tanks are raised by delivering high pressure natural gas vapor thereto from a high pressure bank. The temperature and pressure can be lowered by venting natural gas from the fuel conditioning tanks and/or delivering LNG thereto. The fuel conditioning tanks are connectable to a vehicle's fuel tank via a fill line to deliver natural gas and LNG to the vehicle and to vent natural gas from the vehicle to the fueling station.

Patent CA-2121916-A1 (CA)
Inventor: ERICKSON JON W
IPC: G01B17/00
Filed: 1994-04-05
Abstract: ABSTRACT OF THE DISCLOSURE     An acoustic sensor, useful as an ultrasonic transducer, microphone or hydrophone, uses an optical lever to amplify the motion of the sensor surface and convert it to an electrical signal for image processing. A beam of light (15) from a laser is directed at an oblique angle onto a reflective surface (13) coupled to a sensor membrane (31). The reflected light (16) strikes a position-sensitive light detector (PSD) (17) generating an electrical signal indicating the position of the light spot on the PSD (17). When an acoustic wave strikes the sensor membrane (31), the small movements of the reflective surface (13) result in large motions of the spot of light on the PSD (17), thereby amplifying the acoustic signal. Also disclosed is a multi-element sensor array suitable for linear array or phased array imaging. Three approaches are disclosed for increasing the sensitivity by optical amplification: 1. the vibrating mirror is (46) part of a cantilever that increases the angular deflection of the incident light beam (15). 2. a stationary mirror (M2) is positioned approximately parallel to the vibrating mirror surface. The reflected light beam is reflected back onto the vibrating mirror (M1), and picks up a another increment of the acoustic signal with each reflection. 3. the effective moment of the optical lever is increased within a small volume by the use of two stationary mirrors (M3, M4) to increase the path length from the vibrating mirror (M1) to the position-sensitive detector (17). Two chopped light beams may be directed at a single vibrating surface (M1), and phase-locked loop circuitry used to reduce the signal-to-noise ratio.

Title: Method of insulating a spa using a flexible insulation blanket
Inventor: LIVINGSTON DAVID R
IPC: E04H4/10
Filed: 1994-04-28
Abstract: ABSTRACT OF THE DISCLOSURE      A portable type spa is insulated by a sequence of steps involving initially the preparation of an insulation blanket having a metal foil heat reflective surface on one side with orthogonal dimensions  of  the  blanket  sized  larger  than  the  orthogonal dimensions of the spa shell.  The spa shell is placed on top of the insulation blanket in a preferred method, with the metal foil heat reflective surface facing the exterior of the spa shell.  The spa shell foot well is leveled by shims placed between the bottom of the spa shell and the underlying support surface such as a floor.          The periphery of the insulation blanket is preferably sandwiched between the underside of a spa rim and a top edge of wood skirt panels surrounding the exterior of the spa shell.  The insulation blanket forms a loose bag about the exterior of the spa shell and about plumbing connections on the exterior of the spa shell including warm water circulating tubing projecting outwardly of the spa shell exterior surface.  The blanket is locally slit in the vicinity of the projecting tubing to permit passage of the tubing through the blanket and the slits are sealed by taping the tubing about  the  projecting  tubing.    Alternatively,  the  loose  bag insulation blanket is fixedly mounted to the interior surface of the wood skirt panels below the top edge of those panels just beneath the connection between the top edge of the skirt panels and the rim of the spa shell.

Abstract: ABSTRACT OF THE DISCLOSURE       An illuminated siphon includes a directional light source attached adjacent the upper end of the siphon tube.  The siphon includes a transmission path for the light source along the siphon inlet tube. with an illumination emission point near the inlet end of the siphon tube, and provides utility for the siphon in darkened and confined areas. such as vehicle fuel tanks.  The light source and transmission path are disposed to one side of the siphon inlet tube, thus allowing a clear sight line for the operator along the opposite side of the tube.  The inlet end of the siphon tubs is inserted into the tank and the light source is activated. whereupon the siphon tube may be maneuvered to observe any water or other contaminates in the tank and to position the inlet end of the tube to withdraw those contaminates from the tank.  The tube or pipe to which the light is attached is preferably relatively inflexible in order to provide for maneuverability of the light and inlet end from the opposite end.  Additional flexible tubes or hoses may be secured to the tube to which the light is attached, and a hand or motor operated siphon pump may be secured to the remainder of the apparatus.  Preferably, the various tubes and hoses are transparent to enable the user to observe any contaminates flowing within, and are also resistant to degradation due to contact with most types of fuels.  Use of the siphon provides a great savings to the operator of the vehicle, especially diesel powered trucks and the like.
