Abstract: ABSTRACT OF THE DISCLOSURE    There is disclosed herein an ultrasonic system for detecting internal discontinuities in a body. The system includes: an ultrasonic transducer for directing sonic energy toward a body; a liquid crystal, acousto-optical detector cell for detecting ultrasonic energy passing through said body; and optical system for illuminating said liquid crystal cell; and a liquid medium for coupling the transducer body and cell. The acousto-optical cell includes a pair of substantially rigid covers, a liquid crystal material positioned between said covers and a peripheral spacer and sealing member surrounding said liquid crystal and sealingly engaging said covers. Each of the covers is substantially acoustically transparent and at least one of said covers is optically transparent. The optically transparent cover is a laminate having at least three layers, with each of said layers of said laminate having a thickness much much  less than 1/4 of the wave length of the ultrasonic energy propagating through said layer. The other cover has at least one layer and the thickness of that layer is much much less than 1/4 of the wave length of the ultrasonic energy propagating therethrough. In this construction, it is essential that the acoustical impedence of the cell approximates the acoustical impedence of the coupling medium so as to minimize signal loss and image degradation. Furthermore, the liquid crystal material is usually of the nematic type and is homeotropically aligned.

Abstract: ABSTRACT OF THE DISCLOSURE A phase-locked loop is implemented using strictly digital techniques. The average frequency of the input signal is first sampled by counting the number of  pulses from a  clock source which occur  during a predetermined number  of occurrences  of the  input signal.   Thereafter, the  number of pulses  counted is  divided by  the number of  cycles of  the input signal which occurred during  the counting period to determine  an average number of  pulses  per input  signal  cycle.  The  number  of pulses  which occur between  successive  cycles  of  the input  signal  are  then  counted and compared against the previously determined average.  A count which differs from  the average  indicates a  change in phase  of the  input signal, and after  appropriate  weighting, is  used  to update  the  average to  a new average.  An output  signal is produced when the  number of pulses counted during a  cycle of the  input signal equals  the average number  of pulses determined to occur between successive cycles of the input signal.

Abstract: ABSTRACT OF THE DISCLOSURE A control unit for an inverter having an addressing memory which is loaded with an addressing table by a microprocessor for a respective fre-quency range of the inverter output voltage.  In the addressing table, one column is provided for each addressing combination of the switches of the in-verter, the column containing the addressing combination itself and the number of clock pulses for which the addressing combination will be present.  The columns are interrogated at different speeds depending upon the desired inverter output frequency.  A frequency divider is addressed by a clock generator, the frequency divider receiving a division factor from the memory, the division factor being inversely proportional to the desired inverter output frequency. The output signal of the divider decrements a counter which is loaded with a number of clock pulses associated with the respective addressing combination. Upon achieving a zero count, a new column of the addressing table is provided at the output of the memory.

Title: Single action intermittent dibble planter for  container tree seedlings
Inventor: FLOWERS JOHN F
IPC: A01C11/02
Filed: 1982-06-25
Granted: 1983-03-15
Abstract: ABSTRACT          In a device for mechanically planting forest trees produced in containers, many complicated systems have been devised.  In this invention the planting mechanism receives the seedling by gravity through a loading tube and upon command of the operator a hydraulic jack forces the planting mechanism consisting of dibble, packing wheels and tree ejector, verti-cally into the ground.  As the dibble approached the desired planting depth the packing wheels contact the ground and move upward relative to the dibble until contacting stopper blocks.          In so doing, a mechanical linkage with the packing wheel aims activates an ejector mechanism and the seedling is pushed from the dibble.  At this point sufficient downward pressure is exerted by the packing wheels to fill the planting hole with soil and thus plant the seedling in a vertical position at the desired depth.  Packing is accomplished on both sides of the seedling, rather than one, ensuring perfect soil contact with the roots.  Planting depth can be adjusted by replacing the ejector cradle with one to raise or lower the seedling relative to the packing level.  Another seedling may be placed in the loading tube while planting is in progress and it is released into the dibble when the dibble returns to rest.         The major advantage of this invention is it's simplicity in combining all necessary mechanisms into one unit which requires no special timing for sequential operations.  It relies almost exclusively upon mechanics rather than complicated hydraulic operations which require precise timing for sequential operations.

Abstract: ABSTRACT:         In order to improve the gain of the input dynode of a laminated channel plate electron multiplier an apertured metal sheet is disposed at a small distance (30 um) from the outer surface of the input dynode and is used to provide a small negative field for turning back stray secondary electrons which have sufficient energy to follow trajectories across the input side of the input dynode.  More particularly in order to improve the contrast of an image to be produced the area between the apertures of the input dynode are masked by a material having a secondary electron emission coefficient of less than 2, which material is provided on the outer surface of the apertured metal sheet, the metal sheet being spaced from the input dynode by the insulating material.  A potential of the order of -10 v relative to the input dynode is applied to the apertured metal sheet.  By mask-ing the flat areas of the input dynode, the secondary electrons to be turned back are generally those from the part of the wall of the dynode furthest from the influence of the second dynode.

An  addressable memory  having  memory locations  with addresses corresponding  to those  of the picture  element has stored  in such memory locations  an  address of  a  location in  a  color look-up  memory  for an alphanumeric color, for a graphic color and priority signals.  In the color look-up  memory  at  the  addressed  locations  is  stored  binary  signals representing the color  and intensity of a pixel.   In synchronism with the raster scan of the picture elements of  the cathode ray tube, there is read from the  memory graphic-color addresses,  alphanumeric color addresses and priority signals for each pixel.  One  of the addresses, either the graphic or alphanumeric, is  applied to the color look-up  memory, with the address that  is  applied being  determined  by the  binary priority  signals.  The binary color signals stored at  the addressed color look-up memory location represent varying intensities of a  plurality of predetermined colors.  The color signals  are converted by  a digital to analog  converter into analog signals  which are  applied to  the color cathode  ray tube  to control the color and intensity of each pixel as it is scanned.
