Abstract: ABSTRACT OF THE DISCLOSURE      An automatically-defrosting household refrigerator including a user-operable "vacation switch" effective to enable the operation of the refrigerator in a mode appropriate to a condition of zero usage. When the vacation switch is thrown to the vacation position, the user is assured at once that unnecessary energy consumption will be avoided and the likelihood of failure of the refrigerator while unattended will be diminished.  The mode appropriate to a condition of zero usage in-cludes having the interval between successive automatic defrosting operations extended.  Additionally, the vacation switch may be effective to simultaneously disable an automatic icemaker, to increase the tem-perature set point of the thermostatic control means which maintains the temperature within the refrigerator to disable anti-condensation heaters, and to disable butter conditioner heaters.           There is further disclosed a particular means for extending the interval between successive automatic defrosting operations.  A temperature-responsive switch is mounted so as to be responsive to the temperature of a predetermined portion of the refrigeration sys-tem high side.  The switch is closed at ambient temperature and opens at a predetermined temperature which is reached by the predetermined portion of the refrigeration system high side a few minutes into each operating cycle of the refrigerator compressor.  The temperature-responsive switch is arranged to disable the defrost control timer when the sensed temperature exceeds the predetermined value during each operation of the refrigeration system.  During normal operation of the refrigerator, the temperature-responsive switch is bypassed, and the defrost control timer operates normally.

Abstract: ABSTRACT OF THE DISCLOSURE         An apparatus including at least one horizontal feed pipe from which a mixture of liquid and particulate solid material to be transported is discharged into a high-pressure transport pipe by the action of a driving liquid delivered through a vertical pipe connected to the horizontal feed pipe to apply pressure to the mixture in the horizontal feed pipe through an intermediate liquid having a specific gravity lower than that of the mixture and higher than that of the driving liquid.  Prior to initiation of an operation, the horizontal feed pipe and a lower portion of the vertical pipe below a float mounted therein are charged with the intermediate liquid and an upper portion of the vertical pipe above the float is charged with the driving liquid.  Upon the mixture being delivered by a low-pressure mixture pump to the horizontal feed pipe, the intermediate liquid flows into the vertical pipe and raises the level of the float to return the driving liquid from the vertical pipe to its tank.  Then, the driving liquid is delivered by a high-pressure driving liquid pump to the vertical pipe from which the intermediate liquid is forced into the horizontal feed pipe to thereby discharge the mixture from the latter into the high-pressure transport pipe, thereby transporting the particulate solid material to a predetermined destination.  Mixture feed means and intermediate liquid feed means and their modifications are disclosed.

Abstract: ABSTRACT OF THE DISCLOSURE           A thermal energy scavenger assembly including a plurality of temperature-sensitive wires made of material which exhibits shape memory due to a thermoelastic, martensitic phase transformation.  The wires are placed in tension between fixed and movable plates which are, in turn, supported by a pair of wheels which are rotatably supported by a housing for rotation about a central axis,  A pair of upper and lower cams are fixed to the housing and cam followers react with the respective cams. Each cam transmits forces through a pair of hydraulic pistons. One of the pistons is connected to a movable plate to which one end of the wires are connected whereby a stress is applied to the wires to strain the wires during a first phase and whereby the cam responds to the unstraining of the wires during a second phase. A housing defines fluid compartments through which hot and cold fluid passes and flows radially through the wires whereby the wires become unstrained and shorten in length when subjected to the hot fluid for causing a reaction between the cam followers and the cams to effect rotation of the wheels about the central axis of the assembly, which rotation of the wheels is extracted through beveled gearing.  The wires are grouped into a plurality of independent modules with each module having a movable plate, a fixed plate and the associated hydraulic pistons and cam follower.  The hydraulic pistons and cam follower of a module are disposed at ends of the wires opposite from the ends of the wires at which the same components of the next adjacent modules are disposed so that the cam followers of alternate modules react with one of the cams and the remaining cam followers of the remaining modules react with the other cam.  There is also included stress limiting means in the form of coil springs as-sociated with alternate ends of the wires for limiting the stress or strain in the wires.

Abstract: ENERGY CONSERVING PAVING METHOD AND APPARATUS               USING MICROWAVE HEATING OF MATERIALS           Abstract of the Disclosure Asphaltic concrete constituents or the like deposited in a windrow along a surface to be paved are molded into a preliminary narrow layer of greater height than the final layer of pavement to be formed on the surface and are then heated by directing microwave energy into the preliminary layer.  The heated preliminary layer is then spread out to form the final thinner layer of paving material for smoothing and compaction.  Molding means for the prelim-inary layer and microwave heating means may be carried on a vehicle which travels along the windrow.  The vehicle may also carry mixing, spreading and compaction means or some or all of these elements may be on a separate paver vehicle.  The method and apparatus reduces an unproduc-tive dissipation of energy, which can occur if microwave heating is performed with the paving materials spread out in the relatively thin final layer, by avoiding unnecessarily deep penetration of the microwave energy into the underlying surface that is to be paved.  Auxil-iary heating means, preferably using thermal energy recovered from the exhaust of engines which drive the electrical generators that energize the microwave sources may be used to preheat portions of the surface adjoining the portion overlain by the preliminary layer.

Abstract: LOW POLLUTION INCINERATION OF SOLID WASTE          Abstract of the Disclosure An incinerator system and method wherein pieces of solid waste, such as fragments of wood, are conveyed in such fashion as to become disposed within a fluidized bed of an incinerator vessel.  Preferably the solid waste particles are caused to be somewhat homogeneously dispersed within the fluidized bed.  The solid waste particles may be "pre-dried" or moisture may be added to the particles prior to deposition in the fluidized bed for optimum results, depending upon circumstances.  In one embodiment, the fluidized bed is situated above an air delivery chamber at the bottom of the vessel and supports combustion of the solid waste particles in the fine granular material comprising the fluidized bed. The fine granular material is supported by a perforated plate. The air delivery system channels high temperature air into and up through the fluidized bed until operating temperature is reached and 80 channels ambient air thereafter.  Volatile matter given off by combustion of the solid waste particles in the fluidized bed is burned smokelessly in the vapor space immediately above the bed.
