Abstract: ABSTRACT OF THE DISCLOSURE           A multiple plant  guard  is disclosed for protecting plants against pest attack.  The multiple guard comprises a plurality of plant guards attached together in sequence, each guard comprising a knitted hose-like net structure which is intended to form a casing around the guard.  Connected to the bottom part of the net structure are mutually crossing hanging threads which form the bottom of each guard.  A closure thread is located at the other end of the net structure, this thread when tightened gathering together the upper part of the guard.   The closure thread is knitted integrally with the net structure and comprises a thread of high surface friction, so as to be self-locking when tension is released.   At least one loop formed from the closure thread is attached to the bottom end of an adjacent, corresponding plant guard, such that the closure thread is drawn together when the two plant guards are separated one from the other.

Abstract: ABSTRACT OF THE DISCLOSURE     An improved vehicle suspension system for use on axles of trailers, trucks, and the like.  A pair of wheels are individually rotatably mounted on stub axles attached to a pair of trailing arms which are connected to and extend radially rearwardly from a pair of pivot sleeves.           The sleeves are pivotally mounted on brackets connected to the vehicle frame.  A pair of spaced levers are attached to and extend radially outwardly from each of the pivot sleeves and rotate in unison with the trailing arms   An annular elastomer spring is located between a pair of metal end plates which are pivotally mounted on and located between the spaced levers.  One of the end plates is connected to the lever by a hollow shaft and another shaft is connected to the other end plate and extends through the elastomer spring and into the hollow shaft to maintain the spring in axial alignment.  The elastomer spring, in combination with the dual trailing arm and associated lever mounting arrangement, provides a balanced force on the vehicle tires and trailing arms during vehicle braking and upon the tires encountering road obstructions as well as during static conditions.

Abstract: ABSTRACT           A support column unit for an adjustable-height chair and the like comprises upper and lower telescoping tubular members, a piston-and-cylinder type pneumatic spring located coaxially within the tubular members and having its cylinder member secured to the lower tubular member, and a gravity dependent locking mechanism for locking the piston rod member of the pneumatic spring to the upper tubular mem-ber when the support column is upright and for releasing the piston rod member when the support column is inverted.  The locking mechanism comprises a lock body retained within the upper tubular member and having a bore sized and positioned to permit sliding axial movement of the piston rod member therein.  The lock body has one or more cavities, each one in communication with the bore and containing a locking mem-ber.  The cavities and the locking members are sized and shaped such that when the support column is upright, each locking member falls to a position in which a portion thereof protrudes into the bore, and when the column is inverted, each locking member falls to a position in which it is fully retracted from the bore.  The piston rod member has an annu-lar retaining groove shaped to engage the portions of the locking members that protrude into the bore to achieve lock-ing of the piston rod member to the lock body when the column is upright.

Abstract: ABSTRACT OF THE DISCLOSURE           A system and method for pulse-width modulation of multiple solenoid-operated valves in an electrohydraulic servo  system  employing  a  microprocessor-based  digital controller.    Solenoid-energization  pulse  widths  are identified by comparison of operator command input signals to feedback signals responsive to actual motion at the actuators and loads.  During each modulation period, all solenoids are initially selectively simultaneously energized as a function of binary information stored in an energization control  register,  and  the  shortest  energization  pulse duration is identified.  After a delay corresponding to such shortest duration, during which  the microprocessor may perform other control functions, the solenoids associated with such shortest duration are selectively de-energized as a function of binary information stored in a de-energization control  register.   The  next-shortest  duration  is  then identified, and the process again delays for a time equal to the difference between such next-shortest duration and the previous duration.   The process of identifying pulse durations of  increasing  length and  correspondingly de-energizing the solenoids continues until all pulse durations have been accommodated or  until  the modulation  period terminates,  at which  point  the  entire  control  process rebegins.

Abstract: Abstract of the Disclosure An X-ray radiograph apparatus having a supply maga-zine, a film-removing unit, an X-ray imaging unit, a reference position detector, a suction detector, a dis-tance detector, a discriminator, and a display unit.          The supply magazine contains a stack of unexposed films.          The film-removing unit has a suction unit for holding a film and removing it from the magazine.  The X-ray imag-ing unit forms an X-ray image of a subject on the film fed from the magazine by the film-removing unit. The reference position detector detects that the suction unit is passing a reference position located above the supply magazine.  The suction detector detects that a sheet film has been attracted to the suction unit.  The distance detector detects the distance the suction unit has moved vertically, from the outputs of the reference position detector and suction detector.  This distance is equal to the distance between said reference position and the topmost unexposed film stored in the magazine.          The discriminator determines the number of unexposed films remaining in the supply vessel from the distance detected by the distance detector.  The display unit displays the number of unexposed films, which has been determined by the discriminator.
