Abstract: PLANT GROWING APPARATUS     ABSTRACT OF THE DISCLOSURE   A plant growing apparatus for growing plants having a tube for a rooting medium and openings in the tube for plants grown in the rooting medium to pass therethrough. First and second end members cooperate with open ends of the tube and have openings therein communicating with the rooting medium. One end member has a reservoir to contain water at an essentially constant level, and a support member extends between the two end members to locate them relative to each other. A flexible web extending from the tube is secured to the support member and restrains the tube against excessive relative movement. A wick extends between the end members and is disposed generally adjacent a side of the tube which is adjacent the web and the support member. In one embodiment, the plants pass generally radially outwardly through openings spaced along a side wall of the tube. In another embodiment, the tube can be partially cut in approximately diametrical planes, the cuts avoiding severing the wick so that adjacent portions of the tube can be swung laterally relative to each other to provide faces to receive the plants which can then pass generally axially from the adjacent portions of the tube. In this latter arrangement the plants also can be watered using conventional spraying, and thus the wick can be omitted.

Abstract: ABSTRACT OF THE DISCLOSURE         A  tractor  draft  load  monitoring  system responsive  to tractor and associated implement  load changes.   The  system is particularly adapted  for  a tractor  having  an  engine/transmission  power  unit coupled to its drive shaft.  The power unit is mounted on the frame by resilient mounts that permit measurable angular displacement of the power unit relative to the frame about the drive shaft axis in reaction to changes in the drive shaft torque.  The working depth of the implement, which may be tractor mounted, semi-mounted or a pull type implement,  is raised or lowered by a hydraulic lift system that is controlled by a control valve assembly connected to a source of fluid under pressure.   Interposed between the power unit and the control valve assembly is a transmission cable (Bowden wire  type)  and  lever  system  that  is  operative  to transmit angular displacement of the power unit to an actuating member of the control valve assembly to cause hydraulic actuation of the hydraulic lift device to change the working depth of the implement to compensate for  changes  in  its  draft  load.   Fluid  pressure differential is sensed and fluid flow interrupted to effect incremental changes in implement position until angular displacement of the power unit does not occur.

Abstract: ELECTRONIC CONTROL FOR A DOMESTIC APPLIANCE                 ABSTRACT OF THE DISCLOSURE         An automatic control for various domestic appliances has a ferrite core which surrounds the run winding for the drive motor of the appliance.  The run winding represents the primary winding for the ferrite core, which has a second-ary winding at which a brief output voltage is generated whenever the run winding current changes direction.  This sensor in combination with a voltage zero detector circuit and post-connected logic circuitry generates a voltage pulse and a phase pulse which are respectively related to the voltage level of the drive motor and the motor output torque which is required to operate a movable member in the appliance.  A microcomputer is utilized to generate a representative digital phase number which corresponds to the torque expended in the appliance.  The phase number is utilized in various programs of the microcomputer for auto-matically controlling various functions of the appliance as well as other events in an operational sequence upon the attainment of selected torque levels.

Abstract: ABSTRACT                A modulator terminal employs a CPU module connected via a bus to at least one slave module.  An error condition is detected if a slave module fails to respond to a command by generating an operation acknowledge signal within a predetermined period of time associated with the time requir-ed for the slave module to execute the command. A memory mapping device is utilized to decode CPU address signals and generate related signals on a greater number of output lines coupled to the system bus thereby increasing the number of addressable locations otherwise accessible by the CPU.  Im-proved prioritized bus communication is provided by way of a vectored inter-rupt scheme in which a priority line is coupled in a daisy chain fashion to other slave modules in the system.  In the preferred embodiment the system employs distributed CPU modules employing an interprocessor interrupt tech-nique utilizing a pair of commonly accessible storage devices.  One of the processors may be used as an emulator and a programmable logic array is advantageously utilized in the emulator processor.

Abstract: ABSTRACT OF THE DISCLOSURE         A holddown bar for a hatch cover of a railroad car or the like and method of making the same as well as a railroad car utilizing such a holddown bar are provided herein.  The holddown bar has opposed ends, one of which is adapted to be pivotally mounted to the car, and the other of which is adapted to be releasably latched to the car. A medial portion thereof intermediate the opposed ends is adapted to extend across the hatch cover and carries a sealing gasket in a channel thereof that is adapted to engage against the hatch cover.  The channel is defined by a surface of the holddown bar.  The gasket is secured to the surface by adhesive disposed between the surface and the gasket.  An interlocking member is carried by the holddown bar and has a first part thereof mechanically interlocked to the holddown bar and a second part thereof mechanically interlocked to the adhesive, thereby mechanically to inter-lock the adhesive to the holddown bar.  Thus, the interlocking member can be carried by the holddown bar to interlock the adhesive means in the channel means thereof to the holddown bar.  This overcomes the problem of bonding the adhesive means to the surface means of the holddown bar as the adhesive means will only readily bond to the gasket means.  The gasket means will remain secured in the channel means of the holddown bar of aspects of this invention.

Abstract: ABSTRACT            The stability of heat storage compositions comprising tetrasodium pyrophosphate is increased by raising the pH of the composition to at least 10.6.  The increase in pH is preferably achieved by adding sodium hydroxide or more preferably an alkali metal orthophosphate to the composition.  The preferred additive is trisodium orthophosphate.  The preferred  pyrophosphates are those which comprise less than 1% by weight of tripolyphosphates.          These compositions are novel and may conveniently be produced by calcination of a mixture comprising disodium hydrogen orthophosphate and trisodium orthophosphate.
