Patent CA-2012693-A1 (CA)
IPC: F04C28/24
Filed: 1990-03-21
Abstract: Abstract An improved valve assembly is disclosed for use in a vacuum system.  The valve assembly is provided with a valve which is movable between a first position and a second position.  In the first position, the vacuum reservoir is isolated from the vacuum pump.  In the second position, the valve permits air to flow from the vacuum reservoir to the vacuum pump only through metering ports.  The valve assembly reduces the horse power requirement for initial start up of the vacuum system by restricting air flow from the vacuum reservoir to the vacuum pump.  Also, an immediate vacuum is created in the valve assembly on start up to return oil from a separator to the pump.

Filed: 1990-09-17
Abstract: CHARACTERIZATION OF THE FULL ELASTIC EFFECT    OF THE NEAR SURFACE ON SEISMIC WAVES            ABSTRACT OF THE INVENTION          A method of seismic exploration uses recordings from  both  surface  receivers  and  buried  sensors  to determine the full elastic effect of the near surface layer on an applied seismic wave.  The surface receivers are arranged relative to the seismic source location so that rotational effects may be detected.  Buried sensors are located so that vertical effects may be detected. This full elastic effect may be used in subsequent seismic data acquisition to reconcile the effect of the near surface so that the response of the underlying rock formations may be known.

Title: Apparatus for peeling sausages
Inventor: HALL MARK R
IPC: A22C11/00
Filed: 1991-05-10
Abstract: ABSTRACT An apparatus for removing the skins or casings from sausage products includes an abrasion means suitably in the form of a pair of counter rotating,  rough surfaced rollers through which the  sausages pass after the casings have been slit longitudinally, to tear the casings off the sausages abrasively. Immediately downstream of the abrading means is a suction means, preferably in the form of a perforated suction roller,  which sucks the casing remnants away from the residual sausages.  The apparatus avoids the need for the use of compressed air to loosen and separate the casings from the sausages, thereby drastically reducing the nose level at which the apparatus operates,  and eliminating the risk of bacterial contamination inherent in the use of jets of compressed air.
