Abstract: STONE GUARD FOR HARVESTERS                  ABSTRACT OF THE DISCLOSURE           A stone guard for use with a harvester or combine of the type having a rotatable threshing cylinder and a concave lying contiguous and radially outwardly of the threshing cylinder whereby grain is threshed from a crop fed by a feeder means to the interspace between the threshing cylinder and the concave.  A stone guard door is interposed in the crop flow path between the feeder means and the interspace between the threshing cylinder and the concave.  The stone guard door comprises a main body portion which is pivotally connected to stationary combine structure contiguous the discharge end of the feeder means, and a lip portion hingedly connected to the main body portion.  A detent means carried by the stone guard door normally maintains the lip portion rigid with respect to the main body portion.  The lip portion normally rests on the forward edge of the concave when the detent means is engaged, whereby to maintain the stone guard door in a closed position.  The detent means is adapted to be released by the force or impact of a stone or the like on the stone guard door.  Release of the detent means permits the lip portion to pivotally move about its hinged connec-tion to the main body portion, causing the lip portion to drop off the edge of the concave.  This permits the stone guard door to drop by gravity about the pivotal connection of the main body portion to the combine structure, to thereby discharge the stone or the like before it reaches the interspace between the threshing cylinder and the con-cave.  The main body portion of the stone guard door is pivotally mounted on a rotatable shaft, and means are pro-vided interconnecting the rotatable shaft and the stone guard door whereby rotation of the shaft either manually or by power means causes reclosing and relatching of the stone guard door.  An auxiliary detent means is provided and is operatively related to the lip portion of the stone guard door to maintain the lip portion in fully open unlatched position after the stone guard door has moved to open position, in order to insure that during the relatching operation the stone guard door can move upwardly beyond and in clearing relation to the forward edge of the concave.

Abstract: ABSTRACT In a high pressure spray cleaning apparatus and method there is provided separate pressurized flow circuits to separate inlets of a spray head.  A chemical flow circuit delivers a cleaning chemical fluid under pres-sure and a carrier flow circuit delivers a heated carrier fluid, preferably water and or soap, under a relatively high pressure.  The pressurized clean-ing chemical fluid and heated water are intimately mixed and distributed by a novel spray head.  A power-driven air compressor is coupled to a chemical storage tank containing a cleaning chemical in the chemical flow circuit.  A power-driven positive displacement pump associated with a by-pass unloader valve regulates the pressure of the water from a water tank delivered to a heating coil in which the water is heated in the carrier flow circuit.  When the heated water is not being sprayed at the spray head, it is automatically returned by the operation of the by-pass unloader valve at a reduced pressure to the water tank.  An electric control circuit controlling a heating unit selectively heats the heating coil during certain operating conditions and automatically stops the heating of the coil under other conditions.  The spray head is carried on the end of a hand held wand with control valves to separately regulate flow through each circuit, the spray head having a nozzle that sprays the heated water in a fan-like pattern against a deflecting edge and cleaning chemicals are forced through an aperture into the fan-like pat-tern prior to its striking the deflecting edge to be intimately mixed with the heated water to produce a mixture that strikes the deflecting edge and is deflected therefrom in a highly concentrated form at a high velocity.

Abstract: 23                48,058 ABSTRACT OF THE DISCLOSURE      A tube guide-expander for guiding heat exchanger tubes through tube sheet apertures from a secondary to a primary side thereof and expanding those tubes into contact with  the  apertures'  walls.   The  guide-expander  includes relatively axially displaceable first and second compres-sion  structures  and  elastomeric  O-rings  which  radially expand  into  contact with  the  tube's inner surface when axially compressed between the compression structures.  The first compression structure is abuttable with the tube's end  and has  an axial  opening  therethrough.   The second compression  structure  constitutes  an  elongated element which extends through the opening and has a ram element connected to the end inside the tube and a driving element connected to the end outside the tube.  The ram and elon-gated elements are preferably threadably engaged so as to permit relative axial displacement therebetween when they are relatively rotated.   Such relative axial displacement maintains  selected  degrees  of  axial  compression on  the radially expansible O-rings and provides releasable reten-tion of the guide-expanders in the tubes during guidance of the tubes through the tube sheet apertures.

Abstract: ABSTRACT     A hot-gas engine the power output of which is regulat-able comprises a cylinder defining variable-volume primary and secondary chambers separated by a piston moving in the cylinder, the movement of which piston is transmitted to an external system extracting the mechanical work produced by the engine. The engine has a heater communi-cating with the primary chamber, a regenerator communi-cating with the heater and a cooler containing a supply of working gas at the maximum gas pressure occurring during the work cycle. The engine is provided with valves controlled to pass the working gas to, from and between the primary and secondary chambers in sequential steps. The regulation of the output is accomplished in that during a work-cycle period of increasing primary chamber volume the pressure in the primary chamber is maintained at a high and constant level during a variable fraction of this period, which fraction extends over the work-cycle interval in which a reduction of the power output is obtained for increasing injection time at high and constant pressure. Simultaneously with a reduction of the power output, there is a reduction of the ratio of the maximum and minimum pressures over the work cycle.

Abstract: "DETECTOR FOR MULTIFREQUENCY SIGNALS"            Abstract:   Multifrequency signals, as used in telephone communications systems for example, are detected by filtering an incoming signal in a plurality of filters having passbands corresponding to the possible frequencies in the signal.  The filter outputs are each compared by comparators, with a threshold level dependent on the true RMS value of the incoming signal.  Relative gains are adjusted such that the peak amplitude of a single frequency incoming signal, midway between the center frequencies of two adjacent filters, just corresponds to the threshold.  The pulsed output of the comparators is evaluated to determine whether two and only two tones are present and whether the pulses are present for a sufficient portion of a sampling interval and for at least a minimum number of intervals.

The processors share a common data bus over which data is trans-ferred serially.  The system processor accepts weight and status data transmitted from the scale subsystem processor over the serial data bus.  The system processor operates on this data and keyboard entry data to calculate required postage as a function of parcel origin, parcel destination, class of service and selected special fees.  Printer  setting data is transferred to the postage printing subsystem processor over the serial data bus.  Peripheral devices, such as a document printer or a parcel identification number counter, are controlled by data sent to the peripherals subsystem processor over the serial data bus.  Communications are con-trolled by the system processor which initiates any inter-processor data transfer by means of a control signal which is interpreted by the addressed subsystem processor as a demand for information.

Abstract: 9D-HL-14726-Stone ABSTRACT OF THE DISCLOSURE    A washing machine transmission is disclosed for alternately producing either oscillating agitator drive or basket spin upon rotation of the drive motor in reverse directions.  The transmission includes an input shaft rotated by the drive motor and extending parallel to a concentric spin tube and agitator drive shaft.  An agitator drive ele-ment is oscillated by an oscillation mechanism and in a first direction of rotation of the input shaft is connected to an agitator drive shaft to oscillate the agitator, while in the reverse direction a spin input gear is clutched to the input shaft and drives a spin gear drivingly connected to the spin tube for rotating the basket.  A spring-applied friction brake acts on the spin gear to brake the spin tube, but is released upon rotation of the spin tube for spinning the basket by mating cam surfaces acting between the spin gear and the tube to axially retract the spin gear and release the brake.  A spin neutral is achieved by a solenoid-operated shifter delaying clutching action between the spin input gear and the input shaft, allowing pump-down of the water prior to initiation of the basket spin.
