Abstract: ABSTRACT OF THE DISCLOSURE     A laminated pole for an electrical machine with salient poles is disclosed.  The laminated pole includes a pole body having a plurality of first laminae, and a pole end plate having a plurality of second laminae.  The first laminae are layered and pressed one against another.  The second laminae are welded one to another, and may also be welded to a connecting pin.  The connecting pin protrudes from the pole end plate in an axial direction and is used as a bearing or support member for a pole coil of the electrical machine.  The first and second laminae are made from the same sheet material, have the same outside contour, and are punched with the same punching tool.  Laminated pole end plates according to the present invention are cheaper to manufacture and suffer less pulsation losses and eddy current losses than solid pole end plates.

Abstract: Abstract A method for high resolution maskless chemical and electrochemical machining is described. Preferential etching results from exposing those regions where machining is sought to an energy beam.  Such exposures can increase the etching rate in the base of electrochemical machining by a factor of 103 to 104.  Such enhancement is sufficient to make masking unnecessary.

Title: Combined engine cooling system and  waste-heat driven heat pump
Inventor: LOWI ALVIN JR
IPC: F25B29/00

Granted: 1982-06-29
Abstract: COMBINED ENGINE COOLING SYSTEM AND WASTE-HEAT DRIVEN HEAT PUMP     ABSTRACT OF THE DISCLOSURE     An improved engine cooling system is combined with a jet-driven heat pump system for utilizing otherwise wasted heat from an engine to produce refrigeration and heating of cabin, charge air and other media without requiring additional shaft power from the engine. In a closed cycle, vaporized refrigerant fluid is con-veyed via jet ejectors from the engine cooling jacket at a high pressure and temperature and from refrigerant evaporators at low pressures and temperatures to a radiator/condenser at an inter-mediate pressure and temperature.  The greater portion of condensed refrigerant fluid is pumped back to the engine (boiler) and the balance is throttled into the evaporators (heat exchangers) to pro-duce an evaporative cooling effect.  The vapor resulting therefrom is evacuated by the ejectors and returned to the condenser/radiator.          In the cooling mode, the engine jacket constitutes the boiler in a Rankine cycle power circuit providing motive fluid power for the jet vapor compressor in a reverse Rankine cycle refrigeration cir-cuit incorporating the heat exchangers as cooling coils.  In a heating mode the high pressure vapor is conveyed directly from the engine to the heat exchangers which then serve as condensers to provide condensation heating effects, the partially condensed re-frigerant being further condensed in the radiator.

Abstract: CONTINUOUS COATER Abstract of the Disclosure A continuous coater of the type having a conveyor ex-tending through a coating booth where paint or other material is sprayed onto the products as they are conveyed through the booth. The booth has an air flow control vestibule located adjacent the entrance and exit ports. Each vestibule is connect-ed to an air flow exhaust system and is so configured that it is operative to draw air almost exclusively from outside the booth into the exhaust system so that there is a minimum of input air to the exhaust system from within the booth. The incoming air from outside the booth effectively forms a flow barrier to the egress of sprayed material and/or solvent to the atmosphere through the vestibule entrance and exit ports. Preferably, there is located in each vestibule means for creating an air curtain which functions to minimize the egress of paint or solvent from the coater cabinet and to provide a more nearly saturated atmosphere inside the cabinet.

Abstract: ELECTROGRAPHIC APPARATUS WITH CONTROL SYSTEM FOR  FIXING POWDER IMAGES BY HEAT AND CONTRACT                   A B S T R A C T          An electrographic apparatus by which powder images corresponding to electrostatic images can be formed on receiving material and fixed onto the receiving material by heat and contact is provided with a control system which regulates the quantity of receiving material transported to the fixing device per unit of time 80 as to keep the heat content of heated surface elements of the fixing device suited for the heat capacity of the receiving material even when receiving materials of different weights are used.  The control system can also make the formation of either electrostatic or powder images dependent upon the existance of heat content in the fixing device suited for the heat capacity of the receiving material.  In an appa-ratus employing sheets as the receiving material and pro-viding fixed time intervals for consecutive formations of electrostatic or powder images and for transport of sheets to receive the respective powder images, the control sys-tem can respond to a deficiency of heat content in the fixing device by causing one or a certain plurality of the fixed time intervals to lapse without image formation and sheet transport after each occurrence of one or a certain plurality of the time intervals with image formation and sheet transport.

Abstract: Abstract:    A carburetor for an internal combustion engine has apparatus for readjusting the idling speed to compensate for added electical loads.  The apparatus comprises a by-pass passage one end of which communicates with the air suction conduit of the carburetor upstream of the throttle valve while its other end communicates with the same down-stream of the throttle valve.  A fuel passage supplies fuel into the bypass passage to make a fuel-air mixture. A solenoid valve provided in the bypass passage controls the quantity of fuel-air mixture in response to the operation of an electrical load, such as a heater, fan, lights, air conditioner, etc.  While the idling speed tends to be decreased by such operations it is readjusted to bring the speed back to the rated value by supplying the fuel-air mixture to the air suction conduit.
