Inventor: SIDWELL HERBERT R
IPC: G05D16/20

Abstract: Fluid pressure above a predetermined limit in a fluid pressure system is reduced by operating a relief valve, having its inlet port connected with the system, in a throttling action. A normally seated valve member is maintained in relief valve closed position by pneumatic pressure on a piston in a chamber of the relief valve. A fluid pressure sensor communi-cating with the inlet port generates a signal in response to fluid pressure above a predetermined limit received by a sensor signal processor energized by a source of electrical energy which releases pneumatic pressure in the chamber for a predetermined time interval allowing system fluid pressure to unseat the valve member and exhaust fluid pressure through the relief valve outlet port.

Patent CA-2182099-A1 (CA)
Inventor: WALTERS GLENN J
IPC: A23L5/10
Filed: 1995-01-23
Abstract: A   conductive  structure for use in microwave  food  packaging  which adapts itself to heat food articles in a safer, more uniform  manner is disclosed.  The structure includes a conductive  layer (103) disposed on a non-conductive  substrate (101).  Provision in the structure's conductive layer (103) of fuse links (109) and base areas  (107) causes  microwave induced currents to be  channeled  through the fuse links (109), resulting in a controlled heating. When   over-exposed   to   microwave   energy, fuses break more readily than  the  conductive base areas (107) resulting in less absorption of microwave   energy in the area of fuse breaks than in other regions where fuses do not break. In this way the fused  microwave conductive structure compensates  for the uneven microwave field within a microwave  oven and at the same time provides a safer  conductive  structure less likely to overheat.  In addition, by varying the dimensions of the fuse links and base areas it is possible to design and fabricate different fused microwave  conductive structures having a wide range of heating characteristics.  Thus, a fused microwave conductive  structure permits food heating temperatures to be tuned for food type.

Patent CA-2206213-A1 (CA)
Title: Pressure exchanger
Inventor: HAUGE LEIF J
IPC: F02B33/42
Filed: 1995-11-28
Abstract: A pressure exchanger for transfer of pressure energy from one fluid flow to another with direct mounting of a rotor (10) in a housing (2). The rotor (10) has a central supply manifold (22) for lubricating fluid and step-shaped bearing surfaces with reduced gap clearance towards each rotor end. The lubricating medium flows towards a manifold (11) at each end and from there to the low pressure side via the axial gap clearance. During axial movement of the rotor the manifold pressure increases when the gap clearance decreases at one end while the opposite occurs at the other end, resulting in an axially centering force in the gap surfaces. In the same way steps in the radial bearing surfaces (23) generate a centering force, since a radial movement will cause an increased pressure gradient when there is a reduction of the gap clearance and a decreased pressure gradient when there is an increase in the gap clearance. The end pieces (1, 21) also have a curved countersink (17) at each low pressure port which increases the drainage from the manifold (11). The rotor's ducts are preferably equipped with curved pressure partition walls (24). The end pieces (1, 21) have a pressure duct (14) with direct connection to the high pressure port (15) which pressurizes a limited segment of the pressure plate (13) in order to balance deformations. The end pieces' inlet passages (5, 6, 7, 8) are designed to as great an extent as possible with perpendicular flow cross sections in the form of segments of a circle.
