Patent CA-2040575-A1 (CA)
Title: Apparatus for applying a back pressure to a pump drive shaft seal
Inventor: THOMPSON PETER
IPC: F16J15/40
Filed: 1991-04-16
Abstract: An arrangement for applying a back pressure to a shaft seal of a mechanism such as a pump comprises a piston slidable in a cylinder one end of which communicates with the fluid being pumped and the other end of which contains oil communicating with a sealed chamber on that side of the seal remote from the fluid. Hitherto, the piston has created a preponderance of the back pressure over the pressure of the fluid by virtue of its weight. This preponderance has been very small, and the rolling diaphragm seal needed on the piston has been easily ruptured if the oil has been lost, thereby allowing possibly hazardous fluids to escape. A greater preponderance of the back pressure, allowing the use of a stronger type of piston seal, is provided by urging the piston towards the other end of the cylinder by a spring as well as by the pressure of the fluid. A magnet on the piston remotely actuates a series of flaps hinged along the exterior of the cylinder to give a visual indication of the position of the piston and also effects automatic replenishingof the oil if necessary or operates a remote warning signal when replenishing is needed.

Title: Paint spray gun
Inventor: BURNS MARVIN D
IPC: B05B7/02
Filed: 1991-12-04
Abstract: PAINT SPRAY GUN    Abstract An improved high volume low pressure air (HVLP) operated paint spray gun of the type having adjustable fan air and suitable for operation from a high pressure air source.  The high pressure air passes from a high pressure chamber through first or second parallel calibrated orifices to supply both low pressure atomization air and low pressure fan air for controlling the shape of the spray pattern.  In one embodiment, both orifices supply air to a low pressure chamber which in turn supplies both atomization air and fan air.  A fan air control ring adjusts the flow of low pressure air to fan jet orifices.  Rotating the fan air control ring controls both air flow through the second orifice to the low pressure chamber and air flow from the low pressure chamber to the fan jet orifices.  In a second embodiment, one orifice supplies only low pressure atomization air and the other orifice supplies only low pressure fan air.  A valve adjusts the flow of fan air.

Title: Muscle contraction control by intramuscular pressure monitoring
Inventor: GRANDJEAN PIERRE-ANDRE
IPC: A61M60/839
Filed: 1990-12-04
Abstract: A technique for monitoring the performance of a skeletal muscle (22) used in a cardiac assist system. The skeletal muscle is surgically wrapped about the heart (100), the descending aorta (102), or a chamber connected in series with or parallel to the descending aorta (102) to provide direct assistance when electrically stimulated to correspond with naturally or artificially paced heart contractions. The skeletal muscle (22) must be conditioned to perform constant contraction/relaxation within the range of normal heart rates. This conditioning occurs over a length of time which is too long to be directly managed by medical personnel in a sterile environment except experimentally. The present invention provides apparatus and techniques for managing the conditioning process automatically. In the preferred mode a pressure transducer (106) is implanted within the skeletal muscle (22), producing electrical signals enabling a pulse generator (36) to measure the timing and extent of contraction and relaxation of the skeletal muscle (22).
