Abstract: WATER DISTRIBUTING SOIL SUPPORT FOR PLANT CONTAINERS  Abstract of the Disclosure A soil support for a plant container having a water reservoir below the support in which water-absorbent fabric in the support carries water to the soil base from the reservoir.  To provide uniform watering to the soil, the fabric is provided with pathways to distribute water as evenly as possible throughout the fabric.  These pathways are defined by regions of-non-absorbent fabric which channel the water along the absorbent pathways.  In a practical con-struction, interstices in the fabric are blocked, as with injection moulded plastics, to make the non-absorbent regions.  Also, a main absorbent pathway, which is separated from the soil, is provided along longitudinal edges of the fabric to encourage water flow along the whole length of fabric before the water is brought into soil contact.

Abstract: ABSTRACT A control memory containing both a PLA (Programmable Logic Array) type structure and a ROM type structure for storage of control words.  The ROM type structure is accessed by address inputs from the next address field on the control words stored in the memory.  The PLA section of the memory is accessed by the same address inputs plus inputs from the computer's instruction register making the accessed control word a function of the current computer instruction.  The selection between the PLA type structure or the ROM type structure is made by decoding certain bits of the address input.

Title: Process of reducing density of fast surface states in  mos devices
Inventor: RISCH LOTHAR
IPC: H01L29/76
Filed: 1980-08-08
Granted: 1983-08-16
Abstract: ABSTRACT OF THE DISCLOSURE Fast surface states in MOS devices, such as SCCDs, are reduced by depositing a relatively thin amorphous layer containing silicon and hydrogen onto the SiO2 surface of such devices and annealing the resultant device in a non-oxidizing atmosphere for brief periods of time at a temperature in excess of the deposition temperature for the amorphous layer but below about 500°C so that free valences at the Si-SiO2 interface region are saturated with hydrogen.  Surface state densities of about 4 x 108 cm-2 eV-1 and SCCDs having .epsilon. = 1.10-5 can be achieved via this process.  The process is useful in producing SCCDs with low surface state densities and other MOS devices having low surface generated dark currents.

Abstract: Abstract of the Disclosure A multi-vane windmill rotating in a horizontal plane on a vertical shaft includes frame supported fabric type vanes with the frame hingedly attached at one end to support arms to swing closed and catch the wind in one position and to swing open under centrifugal and wind forces in another position when coming into the wind to reduce air resistance.  Vanes are releasably attached in part to the frame for support in operating position and other-wise slidably secured thereto so as to release and collapse on the frame under extreme wind pressures when the frame is closed and thus spill the wind.  Stops on the support arms provide a limit of movement of the vane frames.  A second embodiment of the vanes includes two overlapping sections normally held in overlapped or closed position by yielding means that permit the sections to separate under high winds to provide an air passage-way through the vane.

Abstract: 1955-70a ABSTRACT                  A calender roll wherein a stationary shaft is spacedly surrounded by a cylindrical shell and carries a row of bearing elements which are movable by pairs of cylinder and piston units and have convex surfaces formed with pairs of fluid-filled pockets adjacent to the internal surface of the shell.  Each pocket receives pressurized hydraulic fluid from the cylinder chamber of a different unit, and the cylinder and piston units for each bearing element are adjacent to each other, as considered in the circumferential direction of the shell.  Those portions of the pockets which are remotest from a symmetry plane including the axis of the shell and extending between the pockets of each pair are bounded by arcuate lands.  The lands which extend circumferentially of the shell are parallel to each other, and the pockets of each pair are separated from each other by a land which is halved by the symmetry plane.  The bearing elements are separated from each other by narrow gaps extending circumferentially of the shell and bounded by parallel side faces of the respective bearing elements. The magnitude of forces acting upon the internal surface of the shell is substantial in the regions of the gaps and increases gradually toward the central portions of the bearing elements, as considered in the axial direction of the shell.
