Abstract: ABSTRACT OF THE DISCLOSURE          Heterostructures having a large  lattice mismatch between an upper epilayer and a substrate and a method of forming such structures having a thin intermediate layer are disclosed.  The strain due to a lattice mismatch between the intermediate layer and the substrate is partially relieved by the formation of edge type dislocations which are localized and photoelectrically inactive.  Growth of the intermediate layer is interrupted before it reaches the thickness at which the left over strain is relieved by 60 degree type threading dislocations.   The  upper  epilayer  is  then  grown  in  an unstrained and defect-free condition upon the intermediate layer where the unstrained lattice constant of the epilayer is about the same as the partially relieved strain lattice constant   of   the   intermediate   layer.    An   unstrained defect-free epilayer of  InGaAs has been grown on a GaAs substrate with an intermediate layer 3-10 nm in thickness of InAs.  Other large mismatch systems are disclosed, including, GaAs on Si with an intermediate layer of GaInAs.

Abstract: ABSTRACT OF THE DISCLOSURE   An approach is shown for eliminating the expense of a plurality of linear accelerators as used in a multiple electron beam free electron laser system.  A single linear accelerator is used to simultaneously accelerate a plurality of electron beams by using an electron beam deflection means such as a bending magnet to cause multiple beams to converge to a single stream of electrons for acceleration by the linear accelerator and then using a similar beam deflection means to re-define the accelerated beams in accordance with their respective energy levels into a similar plurality of output beams.

Abstract: "HIGH SPEED HALF DUPLEX MODEM WITH FAST           TURNAROUND PROTOCOL"             ABSTRACT OF THE INVENTION           A  phase  locked  loop  circuit  which eliminates   the  phase  difference  between  an incoming reference signal and a sampling signal by sampling the incoming reference signal to produce a sampled signal.  The sign of the sampled signal at two sample points is compared to determine in which quadrant a predetermined one of these sample points is located.   The phase adjustment to the sampling signal is dependent upon the quadrant in which  this  sample  point  is  located  and  the magnitude of this sample point.   A large phase difference produces a large phase adjustment so that this sample point is quickly locked onto the zero-crossing  points  of  the  incoming  reference signal.  A small phase difference produces a small phase adjustment and prevents jitter.   The lock onto  the  zero-crossing  point  of  the  incoming reference signal minimizes the data error rate of the modem.

Abstract: ABSTRACT     The invention is an improved bale handling and wrapping apparatus adapted to be fitted on the front-end loader or three-point hitch of a power source.  The round bale handler of the present invention is capable of handling, stacking, transporting, wrapping and dispensing bales of hay.  A spindle probe adapted to engage the bale of hay is mounted for lateral movement on a transverse frame.  The frame extends outwardly to one side of the power source beyond the line of travel.  A removable wrapping arm is fitted on the frame.  The spindle probe can be moved laterally across the frame to accommodate bales of varying diameters, such that the wrapping arm is positioned adjacent the outer most portion of the bale.  Thereafter the spindle is rotated and the wrapping material applied to the bale.          Furthermore, when a bale of hay requires to be dispensed into a hay bunk, the spindle probe is moved laterally to the remote side of the extended frame and rotated in a counter-clockwise direction while the vehicle is driven alongside of the bunk thereby depositing hay beside the vehicle as the machine moves forwardly.

Abstract: ABSTRACT      A ladder stabilizer assembly for stabilizing a ladder is provided.  The stabilizer assembly comprises a telescoping stabilizer polo which is attached at its upper end to the upper portion of the ladder side frame.  The lower end of the stabilizer pole can be pivoted in two ways: away from the ladder side frame and within a pane which is parallel to the plane of the ladder side frame.  The stabilizer pole has an inner member which slides within an outer member so that the stabilizer pole can be extended outwardly in telescope fashion.  The inner member has a cam mechanism at the end which is within the outer pole member.  The cam mechanism consists of a first rubber plug rigidly attached at the end of the inner member and a second rubbed plug swivilably attached on an axis which is parallel to but not coincident with the longitudinal axis of the two plugs. The cam mechanism allows the inner member to be locked relative to the outer pole member by rotating the lower-most stabilizer pole member by about 90°.
