Patent CA-1321891-C (CA)
Title: Differential pressure detector
Inventor: KISHEL JOSEPH F
IPC: G01L9/00
Filed: 1987-12-29
Granted: 1993-09-07
Abstract: ABSTRACT OF THE DISCLOSURE      A  liquid   filled   differential   pressure   detector comprises two pressure sensors.   Each sensor is constructed of one or more capsules, which are pairs of diaphragms sealed at their  peripheries.     The  innermost  diaphragms  are interconnected by a tube which contains a rod assembly.  The interior of  the  sensors  and  interconnection tube  form  a sealed volume filled with a incompressible liquid.  The rod assembly contacts the outermost diaphragm of the sensors and is displaced by expansion and contraction of the capsules caused by a differential pressure change against the outer surface of the sensors.   The motion of the rod assembly is transformed  into  an  electrical  signal  to  indicate  the pressure measurement.  The apparatus is symmetrical about the center point  of the  tube to reduce  error caused by the fluid's  thermal  expansion  by  causing  equal  and  opposite forces  to  cancel,  thereby  preventing  motion  of  the  rod assembly.  An overpressure condition results with one sensor completely  collapsing  with  one diaphragm  bottoming  out against the other, but causes no damage to the capsules due to  complementary  facing  of  the  diaphragm  pairs.    The compliance of the diaphragms is chosen to be small enough to cause any gaseous bubbles to be driven into solution during the  initial  prepressurization  of  the  fluid,  ensuring its incompressibility.  In a second embodiment, the rod assembly is replaced with a core assembly located at the midpoint of the tube, suspended in a magnetic fluid which separates the incompressible fluid into two identical volumes.  The motion of the core assembly, which is due purely to the displacement of  the  incompressible  fluid,   is  transformed  into  an electrical signal to indicate a pressure measurement.

Abstract: ABSTRACT           Manufacture of formable steel strip having a thickness between 0.5 and 1.5 mm, by forming liquid steel in a continuous casting machine into a hot slab having a thickness of less than 100 mm, and hot rolling the hot slab in the austenitic region and below 1100°C, to form strip having a thickness of between 2 and 5 mm.  The strip is cooled to a temperature between 300°C and the temperature Tt at which 75% of the steel is converted to ferrite, and the cooled strip rolled at the above-mentioned temperature between 300°C and Tt with a thickness reduction of at least 25% and at a rolling speed not more than 1000 m/min.  The rolled strip is then coiled.  This process produces a formable thin sheet strip with good mechanical and surface properties and does not require cold rolling.  The properties of the strip can be varied by varying the ferritic rolling temperature.

Abstract: Abstract A filter apparatus is equipped with easily releasable coupling ends (28) of the inlet and outlet connection pieces (27) respectively, and the top wall (11) carrying the inlet and outlet connection pieces is connected un-releasably to the adjoining peripheral wall of the filter housing.  For maintenance or cleaning, the filter appara-tus is exchanged as a self-contained unit.  Since the fil-ter housing itself is not separable in operational terms and there are therefore no sensitive separable seals between housing parts, the housing cross-section can be of any form and therefore especially cuboid for the most effective possible utilization of space (Figure 1).

Abstract: ABSTRACT    A gas power burner having a burner tube closed at one end and a venturi tube disposed within the burner tube with the mouth portion of the venturi tube disposed toward the closed end of the burner tube.  The burner tube is provided with an air aperture in a side thereof at a position along the burner tube intermediate the mouth portion and the burner head portion of the venturi tube.  A blower blows air into the air aperture of the burner tube where the air divides into a first pathway traveling toward the closed end of the burner tube and into the mouth of the venturi tube and also traveling in a second pathway toward the open end of the burner tube.  The air traveling in the primary and secondary pathways provides combustion air for a flame burning at a burner head portion of the venturi located within the outer burner tube.  A gas orifice communicates combustible gas with the mouth portion of the venturi tube and meters and directs gas to the mouth portion for mixing with combustion air from the primary pathway.
