Abstract: NARROW PROFILE POWER HANDLE FOR LINE TRIMMER AN     ABSTRACT OF THE DISCLOSURE   A narrow profile power handle (18) uniquely adapted for use as a flexible line trimmer having improved handling and safety features is disclosed. The power handle is also equipped with a quick connect and disconnect coupling and is useful for driving attachments to produce hand held rotary implements and tools such as brush cutters, edgers, cultivators, drills, etc., hand held reciprocating implements and tools such as hedge clippers, saws, etc., as well as portable water pumps, air compressors, generators, etc. The crankshaft (70) of a two-stroke internal combustion engine (22) is disposed along the longitudinal axis of a narrow profile housing (20)which includes a rear handle having a hand grip portion (35) disposed above and projecting rearwardly parallel to the axis of the housing. The cylinder (58) extends upwardly from the crankcase (76), the carburetor (90) is disposed below the crankcase, the flywheel (82), ignition system (80) and starter (50) to the rear, and the gas tank (88) is disposed below the rear handle. The muffler (44) is disposed along the forward face of the housing for discharging products of combustion forwardly of the housing and away from the operator, thereby permitting the assembly to be rotated for various trimming operations without exposing the operator to the risk of burn injury. A recoil starter handle, (52), a choke control (56), throttle control (57) and ignition kill switch (55) are conveniently clustered around and near the hand grip portion (36) of the rear handle which allows the operator to observe and exercise positive control over both the power handle and the cutter head while starting and operating the engine. The power handle includes a quick disconnect coupling for attaching the portable power unit to drive various attachments. As a result of this arrangement, the power handle is generally symmetrical about the longitudinal vertical plane and is of minimum width. The drive shaft (24) of the line trimmer assembly is aligned with the crankshaft (70) of the engine and a forward handle (38) is disposed above the drive shaft ahead of the engine housing. As a result, the center of gravity of the overall line trimmer assembly is below and between the forward and rearward handles, thereby providing improved balance and maneuverability.

Abstract: Abstract of the Disclosure:     In order to reduce bit errors resulting in a space-diversity broad-band digital radio receiver from selective fading, an amplitude dispersion detector detects the amplitude dispersion caused, if any, by the selective fading in each of IF signals produced by the space-diversity reception and produces a detector output having an amplitude variable with the detected amplitude dispersion and used in combining the IF signals.  The detector may comprise three band-pass filters having different narrow passbands in the IF band to produce filter outputs with amplitudes dependent on first-order and second-order dispersion components of the amplitude dispersion.  Alternatively, the detector may comprise a band-pass filter having a narrow passband repeatedly variable throughout the IF band at a lower frequency to produce a filter output with an amplitude variable with the first-order and the second-order dispersion components and, above all, with a notch-shaped dispersion component.

Abstract: ABSTRACT A packer member comprising corrugated rings, particularly for seating the annular clearance between the casing and tubing of an oil well.  The packer is carried upon a collar presented by a member coupled into the tubing, and axial compression of the packer flattens the corrugations, expanding the rings radially so that they make a tight fit with the inner wall of the casing by either penetrating it or distorting against it;  at the same time the axial compression makes a tight fit between the inner edges of the rings and the collar on which they are supported.  The packer may comprise a stack of corrugated rings alternately of harder and softer material, and occasional robust rings may add stability.

The integrating net-work is AC coupled to a bandpass filter which passes signals having frequencies corresponding to changes in capacitance of the object caused by an intruder and these signals are applied to a threshold circuit for activating an alarm when an intrusion occurs.  Tamper alarm circuits are provided to detect unauthorized disconnection of any portion of the protected object (decrease capacitance) or the addition of capacitance in an attempt to de-feat the system.

Abstract: SPRAY ASSEMBLY CONSTRUCTION Abstract of the Disclosure A spray assembly including an improved control valve is disclosed which is designed for heavy industrial usage to enable application of air and/or atomized liquids to be applied to the working surfaces of various types of forming apparatus such as molds and dies for example. The control valve utilized in the spray assembly of the present invention incorporates a piston actuated plunger assembly which is designed for extremely rapid operation whereby substantially maximum liquid fluid flow may be obtained almost instantaneously, Additionally, the spray assembly is designed so as to enable application of either one fluid alone such as blow air or both air and liquid. Also, the plunger is positioned so as to provide substantially unobstructed liquid flow into the air stream for atomization when in a fully open position thereby enabling large volumes of liquid to be applied within relatively short cycling time. An adjustable stop is also provided so as to allow modulation of the liquid flow should this be desired. Only a single moving valve member is required which is controlled by pressurized air so as to provide extremely rapid on/off cycling thereby assuring long dependable operation as well as enabling relatively rapid repair.

Abstract: METHOD FOR ASSEMBLING SLIDE FASTENER STRINGERS          Abstract of the Disclosure Disclosed herein is method for assembling a pair of slide fastener stringers each having spaced sections in continuous rows of scoops and an apparatus for the same.          The leading edge of the scoop row in the leading stringer is detected by a probe inserted into the guide groove of the binder member for the scoop row.  The engagement of the leading edge and the claw of the probe retards the progress of the leading stringer thereby retarding the rotation of the feed roller for the leading stringer while increasing the speed of the rotation of the other feed roller for the trailing stringer, which is connected to the first feed roller through a differ-ential transmission mechanism.  After both of the stringers are brought into right alignment for exact engagement in the binder member, the claws disengage from the leading edges of the scoop row in the stringers and come out of the spaced sections.  In this condition, the spaced sections in the stringers are detected individually by detecting lever means.          Detector means detect the movement of the detecting levers and judge whether the proper interengagement of the stringers is obtained or not so that it produces either a signal to protrude the claw into the same spaced section following insertion of the detecting lever or a signal to stop operating the feed rollers.
