Abstract: TITLE OF THE INVENTION       METHOD OF FABRICATING A WET-ROTOR CIRCULATOR      AND CIRCULATOR PRODUCED THEREBY     ABSTRACT OF THE DISCLOSURE A wet-rotor circulator in accordance with the present invention includes a drive motor coupled to the impeller of a fluid pump.  The drive motor includes a rotor assembly enclosed within a fluid impermeable jacket and a stator assembly for driving the rotor.  The rotor is coaxially supported within the jacket by bearings which are permanently secured in place by circumferentially crimping sections of the jacket radially inwardly to shape-lock the bearings to the jacket.  The crimping takes place during an assembly step in which an applied magnetic field causes substantially instantaneous deformation of the jacket without disturbing the coaxial relationship between the rotor shaft and its support bearings.

Abstract: Abstract In a heating installation comprising a boiler and heat pump of which the liquefier is disposed in the return line of the hot water circuit, a multi-stage compressor of the heat pump and the boiler are subjected to a temperature regulating device. The regulator (28) is subjected only to an outside temperature sensor (22) and a return temperature sensor (21) disposed directly behind the liquefier in the return line.  The regulator contains an integrator (30) and, between the outside temperature sensor and the regulator, there is a desired temperature converter (31) as well as a limiter (32) therebehind which limits the desired temperature signal to the upper limit (55°C) of the compressor (20) of the heat pump.  The output signal (y) of the regulator (28) is fed with different response threshold values to the threshold value operating switches (33-36) associated with the compressor stages (I, II, III) and the boiler (11), the boiler operating switch (363 having the highest response threshold value.  The supply water can be fed to the return line (15) only by way of the radiator or radiators (13).

Abstract: ABSTRACT A sheet feeding apparatus with a sheet support tray, a rear vacuum plenum chamber adapted to acquire the rear portion of a sheet, a front vacuum plenum chamber positioned over the front of the sheet and adapted to acquire the front portion of a sheet, sheet transport means associated with the front vacuum plenum to transport a sheet acquired in a forward direction and an air knife positioned at the rear of the stack of sheets to inject air between the trailing edge of the top sheet in a stack and the remainder of the stack. In a specific embodiment the trail edge of a sheet in a stack is separated by the air knife, acquired by the rear vacuum plenum then acquired by the front vacuum plenum and transported in a forward direction. As the trailing edge clears the rear vacuum, the rear vacuum which together with the air knife is continuously activated, acquires the next sheet in the stack. In this way the speed of the sheet feeder can be very high since sheets are separated and acquired by the feeder simultaneously with transporting them off the stack. Preferably the air knife includes preacquisition fluffer jets to initially loosen the top few sheets in the stack and lateral converging air streams to facilitate separation of the topmost sheet in the stack.

Abstract: ABSTRACT OF THE DISCLOSURE     Engine timing apparatus includes a timing light, cylinder clock signal circuitry, a cylinder counter, a cylinder comparator, first, second and third timers, a trigger pulse generator, operator control buttons, and a computer.  The first timer measures a first time period between firing of the No. 1 cylinder, and the second timer measures a second time period between firing of the cylinder preceding No. 1 and the firing of the No. 1 cylinder.  The computer derives from the first and second time periods a first digital value which represents the angular degrees from firing of the cylinder preceding No. 1 to firing of the No. 1 cylinder.  Each time the comparator output signal is produced, the third timer initiates an adjustable time period, and the trigger pulse generator triggers the timing light at the end of the adjustable time period.  The operator control buttons include buttons which cause a second digital value to be increased or decreased.  The computer uses the first and second digital values and the measured first time period to control the adjustable time period of the third timer.  When the operator has varied the second digital value so that the flashing of the timing light corresponds to top dead center of the No. 1 cylinder, the computer causes an angular value to be displayed which represents the angular relationship between firing of the igniter and top dead center of the No. 1 cylinder.

Abstract: Method and Apparatus for Abrasively Machining a Workpiece Abstract of the Disclosure A method and apparatus for abrasively machining a workpiece includes the establishment of an eddy-current in the workpiece at an area where an abrasive tool contacts the workpiece.         Heretofore it has not been possible to adaptively control an abrasive machining operation as a function of changes occurring in the microstructure of the workpiece during the machining operation.  In particular, it has not been possible to detect non-visible grinder burn on the surface of a workpiece during a grinding operation.         The present invention solves the above problem by providing an abrasive machining apparatus having a means for establishing an eddy-current in a workpiece at an area where a tool contacts the workpiece and sensing any change in the eddy-current in response to change in the microstructure of the workpiece resulting from the abrasive machining operation.         The method and apparatus of the present invention is particularly useful for grinding hardened ferrous metal workpieces without incurring grinder burn defects.
