Title: Process and apparatus for generating a vacuum
Inventor: ANSORGE JOACHIM
IPC: F04F5/20
Filed: 1992-12-08
Abstract: A process for the generation of a vacuum in a vessel comprises generating a vapour by heating a reservoir of a paraffin wax, discharging the vapour through an inlet into a gas entrainment zone connected to the vessel, thereby generating a vapour jet in the entrainment zone, allowing gas from the vessel to enter the vapour jet, allowing the vapour jet containing the gas to pass to a condensation zone, condensing vapour from the vapour jet in the condensation zone and separately recovering the condensed wax and the uncondensed material. Apparatus for the generation of a vacuum comprises a reservoir of a paraffin wax, heating means to generate a vapour from the paraffin wax, a vapour conduit providing a passage for the vapour, a pump vessel, which vessel comprises a gas entrainment zone, a vapour inlet connected to the vapour conduit and of a form whereby vapour entering the pump vessel is formed into a vapour jet extending into the gas entrainment zone, a gas inlet whereby gas entering the pump vessel is caused to contact the vapour jet, a vapour condensation zone arranged to receive the gas and vapour jet leaving the entrainment zone, cooling means to condense vapour in the vapour condensation zone and means to recover separately from the condensation zone the condensed vapour and tha gas. The paraffin wax is preferably a synthetic wax, in particular a wax prepared by a Fischer-Tropsch synthesis.

Title: Automatic backup battery connection
Inventor: ST JOHN PAMELA M
IPC: H05K1/11
Filed: 1993-02-19
Abstract: A method and apparatus are described for selectively activating a secondary power source, such as a backup battery, for an electronic device, such as dynamic RAM.  A connector is described in conjunction with a circuit board including a first contact coupled to the backup battery, and a second contact coupled to the corresponding input for backup power associated with an electronic device.  In this state, an open circuit is presented such that the battery is isolated from the electronic device.  A socket is described for cooperating with the connector, which includes mating contacts corresponding to the first and second contacts previously described, and means for establishing electrical continuity between these mating contacts.  In this manner, a completed circuit is established between the battery and the electronic circuit device when the socket is attached.  A bypass connection is also described for maintaining connection between the battery and the electronic device independent of the socket, so that the circuit board may later be removed without threatening loss of accumulated memory contents.
Patent CA-2092585-A1 (CA)
Inventor: MORAND MICHEL
IPC: B65D25/52
Filed: 1993-03-26
Abstract: A dispenser for dispensing a sheet of perforated paper towelling off a roll of paper towelling.  The dispenser has a casing with roll mounting means in its upper portion and an outlet at the bottom.  The outlet is substantially narrower  than  the  width  of  the  towelling.   A  roller  is mounted in the casing for guiding the towelling from the roll mounting means  to  the  outlet.   The  roller  maintains  the towelling  at  its  full width.   The  towelling  is  gathered inwardly in passing from the roller to the outlet.   Upon pulling the towelling out of the dispenser,  the towelling begins to tear inwardly from its edges along the first line of perforations as the first line of perforations passes over the roller to separate a sheet from the remainder of the towelling.   The tearing operation is completed outside the casing leaving a tail end of towelling to be grasped during the next dispensing operation.

Title: Inductively coupled plasma spectrometers and radio-frequency power supply therefor
Inventor: FARRELL REGIS C
IPC: G01N21/73
Filed: 1993-04-15
Abstract: Abstract of the invention The invention provides methods and apparatus for atomic emission spectroscopy and for mass spectrometry which make use of an inductively coupled radio-frequency plasma torch.  A radio-frequency power supply supplies energy to a plasma induction coil via reflectometer means and a matching network. A signal indicative of reflected power generated by the reflectometer is used to set the frequency of the power supply to the resonant frequency of the matching network and plasma induction coil, thereby ensuring the maximum efficiency of power transfer irrespective of the state of the plasma. Preferably a solid state power amplifier is employed in conjunction with a lower power variable frequency oscillator. Means for ensuring proper ignition of the plasma while maintaining the frequency of the power generator within a governmentally specified frequency band are also provided.

Title: On-stream time for ebullating bed reactor
Inventor: HOOKHAM DAVID E
IPC: C10G49/12
Filed: 1993-04-30
Abstract: ABSTRACT OF THE DISCLOSURE    A downcomer for use  in ebullating bed reactors that  is perforated  along  its  length  within  the  reactor.    These perforations are sized slightly smaller that the solid catalyst particles used in the reactor in order to screen out these solid particles and prevent their flow or movement into the downcomer from the reactor.  As a result of the perforated downcomer, any liquid separated from the fluidized medium and collected in the downcomer will flow back through these perforations and into the reactor when the ebullating bed is operating at its normal level; however, when the ebullating bed is operating at an upset level condition, the liquid in this fluidized medium will flow in the opposite direction and will pass through these perforations into the  downcomer  in  order  to  maintain  a  minimum  flow  to  the ebullating pumps.

The neck is disposed in the frame and connected to the back of the head of the frame on the opposite side of the head from the arms of the frame. Adjacent to the tongue, the neck runs horizontal in length away from the head of the frame.  A body is disposed within the frame and is connected to the neck of the frame.  The body runs horizontal in length from the end of the neck.  The Body and the neck of the frame are not flexible.  The body and the neck of the frame form a handle to keep your hands at a safe distance away from the heat of the oven rack when the oven rack bars are position inside the axial housing of the clasp created by the arms and tongue of the frame.
