Abstract: ABSTRACT     A harvester for harvesting only the blade or lamina from a mature kelp plant uses a plurality of harvester mechanisms for movement through a kelp bed adjacent the sea bottom.  Each mechanism has a pair of helically formed spindles parallel to each other for relative counter-rotation, the helices being of opposite hand.  A kelp stipe, encountering the spindles is moved upwardly thereby to bring the attached lamina into a channel forward of the spindles, adjacent which channel a cutter is positioned.  When the lamina starts to engage the spindles they separate slightly and operate a linkage which in turn actuates the cutter to sever the lamina.  The severed laminae are collected in a basket connect to the harvesting mechanisms.  By harvesting only the lamina the plant can regenerate a new lamina and it is possible to have repeated harvests from a single plant.

Abstract: DEVICE FOR CLAMPING CONDUIT            Abstract of the Disclosure A device for clamping conduit which includes a U-shaped body portion having a recess therein located between two legs of the body portion, and a toothed jaw portion positioned at the bottom of the recess for engaging a pipe or conduit.  A clamping portion is hingedly secured to one of the legs of the body portion at the free end thereof by an integral flexible hinge, and is adapted to fold about the hinge to enclose the pipe or conduit in the recess by means of a second toothed jaw portion formed on the clamping portion.  Each of the legs of the body portion carries a protuberant apertured flange with the apertures in the flanges positioned for alignment with corre-sponding apertures in the clamping portion when the clamping portion is pivoted to its recess closing position.  The aligned apertures in the flanges and clamping portions can then be used for receiving fasteners extended through these apertures and into a supporting surface such as a wall or the like.

Abstract: IDLE SPEED CONTROL ACTUATOR     ABSTRACT OF THE DISCLOSURE         An idle speed control actuator is used to maintain a constant vehicle engine idle speed in response to variations of the load on the vehicle engine.  The actuator responds almost immediately to an increase in the load on the engine to prevent the engine from stalling, but reduces idle speed slowly when the load on the engine is reduced during idle conditions or when the throttle control lever is returned to the idle position so that the actuator does not have to "hunt" for the proper engine idle speed.  The actuator includes a control plunger which is engaged by the throttle lever when the latter is returned to its engine idle position, so that the position of the throttle lever, and, accordingly, the opening of the carburetor butterfly valve which sets the engine idle speed, is varied in accordance with the position of the plunger.  The plunger is positioned by a differential pressure responsive diaphragm, which is responsive to the pressure differential between engine manifold vacuum and ambient atmospheric pressure.          Since the engine manifold vacuum varies in accordance with the load on the engine for a given throttle setting, the diaphragm responds accordingly to move the plunger to the proper setting.  Since the throttle lever engages the plunger during the engine idle condition, the proper setting of the plunger will also properly position the throttle lever to establish the correct engine idle speed.

Abstract: (Case No. 7008) ABSTRACT OF THE DISCLOSURE    The primary winding of a saturable transformer is coupled to an alternating current source by a series tuned filter network.  The transformer secondary winding is coupled to a load network by a second series filter tuned to the source frequency to block harmonics generated by the satura-tion limiting action of the transformer, which occurs below the normal voltage level of the source and regulates the output voltage supplied to the load within predetermined limits over the source operating voltage range.  The first filter is tuned at a predetermined level above the source frequency to cooperate with the equivalent inductance of the unsaturated transformer and output network to hold the secon-dary output in phase with the input signal at low levels of the source voltage.  The first filter further cooperates with the reduced equivalent inductance of the saturated transformer and output network to change the effective frequency tuning to shift the phase of the secondary output with respect to the input signal at normal source voltage levels.
