Patent CA-1041775-A (CA)

Abstract: ABSTRACT OF THE DISCLOSURE   A closed cylinder contains a thermally driven free piston oscillating between hot and cold ends of the cylinder which ends are respectively connected to a thermal lag heating chamber and a turbine/cooling chamber. A thermal regenerator is provided within a cylinder bypass which bypasses a portion of the cylinder between hot and cold rebound chambers which include, respectively, the hot and cold ends of the cylinder. The hot rebound chamber also includes the thermal lag heating chamber. The heating chamber has sufficient thermal lag properties for substantially heating gas therein as the piston is rebounding away from the hot end of the cylinder, thereby sustaining piston oscillation. The cyclical heating and cooling of the working gas in the heating and cooling chambers and in the regenerator as the displacer piston coasts up and down within the bypass region of the cylinder between the rebound chambers produces a modulated pressure for driving the turbine via a nozzle-like conduit interposed between the cylinder and the turbine. The modulated pressure is augmented by orienting the hot end of the bypass and an inlet port of the thermal lag heating chamber so that, while the piston is coasting toward the cold end of the cylinder, gas flowing into the hot end of the cylinder via the bypass is directed into the cylinder in a stream which passes into the heating chamber inlet port and thence into the heating chamber for further heating therein while the piston is still coasting toward the cold end of the cylinder. The overall cycle of this heat engine is regenerative and may loosely be referred to as a modified Stirling cycle. The turbine or motor may drive a generator or alternator to produce electrical power. The turbine may be replaced by a different rotary motor or other fluid driven load.

Abstract: S P E C I F I C A T I O N                 ELECTRONIC AIR CLEANER          ABSTRACT OF THE DISCLOSURE     An electronic air cleaner, in which an air inlet, a mechanical prefilter, an electrifying cell, an electrostatic collector cell, a chemical filter and an air outlet are ar-ranged in the order in a casing of insulating material. The electrifying cell comprises a grounded conductive pro-tection net located behind the mechanical prefilter, a plura-lity of thin-wire electrodes and a plurality of grounded con-ductive plates.  The thin-wire electrodes are less than 50 microns in diameter and arranged in appropriate intervals at substantial rectangles with an air path from the air inlet to the air outlet.  Each of the grounded conductive plates has one end attached to the protection net and backwardly ex-tending between adjacent two of the thin-wire electrodes along the air path.  The electrostatic collector cell comprises the entending parts of the grounded conductive plates and a plu-rality of negative high voltage conductive plates respectively connected to the thin-wire electrodes and laid between the grounded conductive plates.  A direct current voltage less than 4.2 kilo-volts is applied to the negative high voltage conductive plates.  An electric fan causes a flow of air from the inlet to the outlet to perform highly effective air clean-ing under preventing the ozone development.

Abstract: IMPROVED BACONWEIGHER            ABSTRACT OF THE DISCLOSURE              A combination bacon slicing, segregating and weighing machine is provided.  The slicing machine has a slicing blade and controls for determining the rate of feed of the bacon belly to-wards the slicing blade and, consequently, the slice thickness.          Receiving and conveying structure is associated with the weigh-ing machine and receives the sliced product coming from the slicing machine.  Control apparatus is designed for inter-ruption of the operation of the feeding mechanism by appropriate controls when the slices are at a weight less than the prescribed draft weight.  The apparatus then provides for weighing and registering the weight of the accumulated light weight group of sliced product and for counting the number of slices in the lighter group.  The apparatus calculates by subtracting the weight of the group from a heavier draft target weight and multiplying the weight difference by the ratio of the slices in the lighter group to the weight of the lighter group to determine the number of slices to be added to produce the target weight without changing the slice thickness.  The number of slices required for the target weight rounded out to the nearest whole integer is then calculated.  Thereafter, the error produced by rounding off to the nearest whole integer is corrected by multiplying the first feed rate by the ratio of the number of slices calculated to produce the target weight by the number of slices rounded off to the nearest integer to provide a new feed rite which will produce a number of whole slices at the right thickness in making up the added weight to produce the draft target weight.

Abstract: CYCLONE SEPARATOR GAS TUBE HEAT DISSIPATOR          Abstract:  A cyclone separator having heat dissipating and structural re-enforcing means.  The cyclone separator has a gas outlet tube passing through the top of the separator shell and extending into the cyclone body.  In order to prevent high temperature build-up the connection of the outlet gas tube with the shell is specially designed in order that heat contact be with only one side of the outlet gas tube wall.  The gas outlet tube has a lower portion extending into the top portion of the separator shell and is connected to an inverted frusto-conical upwardly diverging wall.  This wall is also connected to the top wall of the cyclone separator.  This structure provides an annular space to dissipate hear from high temperature gases which would otherwise in conventional structures contact both sides of the wall of the gas outlet tube and break down or liquify the metallic structure.  Radial heat transfer fins are preferably employed within the annular spase connecting the exterior gas outlet tube to the diverging wall and the top of the cyclone separator for additional heat transfer and dissipation to the outside atmosphere and also as a strenghtening means.  The inter-ior walls are insulated with conventional ceramic or refractory material to minimize heat losses.
