Patent CA-1103574-A (CA)
Inventor: REED ROBERT D
IPC: F23L7/00

Granted: 1981-06-23
Abstract: ABSTRACT OF THE DISCLOSURE      Apparatus for burning combustible gases at very low pressure, in combination with a combustion chamber having an opening through one wall.  The burner system comprises a burner tube for supplying the low pressure gas, comprising a tube of selected diameter and length, with an annular flange extending inwardly at the end inserted into the opening in the wall.  A steam tube of smaller diameter than the burner tube, is mounted axially inside of the burner tube, and has a closed end in the plane of the inwardly extending flange.  A plurality of orifices are drilled through the closed end of the steam tube at a selected angle to the axis, whereby when steam is supplied to the steam tube, at 5# gauge or more, high velocity jets of steam will flow outwardly through the orifices along the surface of a cone, and will aspirate into the steam streams the low pressure gas, which will be mixed with the steam, and will flow as a conical wall of steam and gas.  This high velocity flow will aspirate air into the steam-gas streams for provision of air for burning the gas fuel completely.

Abstract: ABSTRACT OF THE DISCLOSURE         A plurality of  thermocouples are connected to reading circuit conductors at an isothermal junction block, for selec-tive connection to the input of an operational amplifier.  The resulting output signals from the operational amplifier are moni-tored and stored in a computer.  A reference thermocouple is se-lectively connected to the operational amplifier through a refer-ence junction compensator -- the reference junction compensator provides a compensated connection of the reference thermocouple with the reading circuit conductors.  The signal at the output of the operational amplifier when the reference thermocouple is connected at the input is also monitored by the computer and stored for processing.  In the computer, the signal sensed and stored when the reference thermocouple is connected to the oper-ational amplifier is subtracted from the sensed, stored signals generated when the other thermocouples are connected to the oper-ational amplifier.  This subtraction nullifies the offset error of the operational amplifier (and the offset error of other read-ing circuit electronics such as the multiplexer selectively con-necting the thermocouples to the operational amplifier), and it corrects the temperature indications of the thermocouples by eliminating the error of the cold junction at the isothermal junction block.  These corrections are inherent, and are main-tained without any surveillance or periodic adjustment.

Abstract: ABSTRACT OF THE DISCLOSURE           The specification describes a measuring transformer for capacitative measuring of liquid levels consisting of two electrodes electrically insulated from each other, where an electrode band is embedded in an enamel layer on a steel body serving as opposite electrode, and where the partial capacity between this electrode and the steel body, being a function of the filling level, is determined by the share of field lines passing through a liquid on their path from the electrode to the steel body on the side facing away from the steel body.  A metallic screening band which is wider than the electrode band and which screens the electrode band along part of its length is embedded in the enamel layer between the electrode band and the enamel surface.

Abstract: ABSTRACT OF THE DISCLOSURE:         Process for stacking strips of fixings, each fixing having a head and a shank,the fixings being connected together parallel to each other by  at least one retaining strip, comprising the steps of: forming a transportation slot by means of two opposite support elements, holding the fixings in the transportation slot freely suspended by their heads, moving alternately each of the support elements away from the other so that at any time one support element remains in its supporting position and the other support element releases the heads of the fixings in such a way that the strips of fixings carry out a rotating movement around an axis parallel to their length as they fall down under the influence of gravity, and are collected after rotating through 90°.  The alternate moving of each said support elements provides the falling down of fixings with their heads pointing in opposite directions.

Abstract: FILTER UNIT                ABSTRACT OF THE DISCLOSURE               The arrangement of the disclosure comprises a filter unit having an upper, inlet chamber and a lower, out-let chamber.  A hydrophilic filter separates the upper chamber from the lower chamber and a lower placed hydrophobic filter or membrane separates the lower chamber and the upper chamber.  A liquid reservoir is provided in the first chamber between the filter and membrane, and a gas reservoir is provided in the second chamber between the filter and membrane.             A liquid admitted to the upper, inlet chamber with a forward differential pressure, that is with the pres-sure in the upper chamber larger than that in the lower chamber, will flow through the upper hydrophilic filter into the lower chamber.  If any gas accumulates it cannot accumulate above the level of the lower hydrophobic membrane.  Accordingly no gas flows out of the lower, outlet chamber in the for-ward direction.  If there is a reverse differential pressure, reverse liquid flow is prevented by the hydrophobic mem-brane and by air trapped above the lower hydrophobic filter against the upper, wet hydrophilic filter.  If liquid supply to the upper chamber fails and a forward pressure differen-tial exists between chambers, forward gas flow is prevented by the wet upper hydrophilic filter and the liquid trapped above the hydrophobic filter.  Therefore the unit filters the liquid flow, vents gas in the outlet chamber to the inlet chamber, prevents forward gas flow, and prevents reverse liquid flow.

Abstract: TRANSFER UNIT AND METHOD OF MOVING    STACKED LUMBER AND THE LIKE                 Abstract of the Disclosure A method of moving and transferring a stack of lumber or the like from a side by side row of stacks wherein the stacks are supported on ground placed chocks positioned at the ends of the stack.  The method involves engaging with the tines of a forklift truck a transfer unit provided with a ground engaging support means at its forward end, and lifting the transfer unit with the lift truck tines so that the transfer unit is at least partially maneuverable by movement of the lift truck.  The transfer unit is then forwardly and progressively moved under the selected stack by forward movement of the lift truck so that the transfer unit engages the stack and pushes the near chock forwardly and beyond the center of the stack so that the weight of the stack is trans-ferred from the chocks to the transfer unit.  The transfer unit supported stack is then withdrawn from the row of stacks by backing the lift truck away from the row.  The lift truck tines are then lowered to a point where the transfer unit is fully ground supported, and the lift truck repositioned to where the tines can engage the transfer unit supported stack from the side, and lift and transport it to a storage location away from the row of stacks.
