Abstract: ABSTRACT OF THE DISCLOSURE            The kite comprises two right-angled triangular frame-works symmetric with respect to a common side which forms a right angle with another side of each triangle.  The triangular frames are pivotably interconnected through that common side, and a bi-lateral symmetric wind-bearing surface is carried by the frame-works.  An arcuate resilient member connects the free ends of the other sides of the triangles to each other and has a spring con-stant greater than five times the weight of the kite divided by a distance between a point of attachement of a line to the kite and a point of attachement of the resilient member to one of the triangular frameworks and less than one half a tensile strength of a kite string attached to the kite.

Abstract: ABSTRACT OF THE DISCLOSURE       Apparatus for use with a pair of thermo-plastic strips of the type illustrated in Abildgaard Laboratories United States Patent No. 3,608,117 dated September 28, 1971 wherein one strip is formed with studs longitudinally spaced at intervals and a second strip apertured and counterbored at the same intervals is used to bind sheets apertured at the same intervals at locations spaced inward from one marginal edge is described.  A pressure bar is first manually moved to operative position and a handle compresses the strips together by exerting a controlled force on the pressure bar.  The handle then initiates movement of a sup-port for a knife consisting of a length of metallic ribbon material having spaced horizontal stretches in horizontal align-ment with excess stud lengths of the first strip projecting through the second strip, the ribbon being under tension to hold such stretches taut.  As the support moves toward the studs a current is passed through the ribbon, heating it so that the ribbon functions to cut off the excess stud length slightly below the second strip.  The current then is terminated as the support moves upward forcing heads on the stud stubs filling the counter-bores in the second strip.  By this time, the ribbon has cooled and functions to cool and harden the heads.  Retraction of the handle returns the support to initial position and releases the pressure bar.  The handle also actuates a punch for the apertures in the sheets, the punch being located at a different station in the machine from the binding mechanisms.

Abstract: ABSTRACT OF THE DISCLOSURE         Artificial ice surface plants contained within an enclosure, utilize a ceiling cold air duct system operatively connected to a refrigeration unit so that the entire air content of the building housing the ice surface is maintained at approximately 26°F to 28°F which is quite comfortable for normal winter activities such as curling, ice hockey or ice skating.          The warmer air from the building is withdrawn, cooled and hence de-humidified, and then discharged back near the ceiling area so that any turbulence takes place well above the activity area and the cooler air gradually settles towards the ice surface.  Heat ge-nerated by the refrigeration unit may be passed through a heat exchanger to heat other areas of the building or may be discharged externally.  If the out-side ambient temperature drops below approximately 14°F, then outside air may be drawn into the system.          All of these alternatives assist in conservation of energy and are automatic in function and are control-led by a single automatic thermostat control within the buildings.

Abstract: IMPLANTABLE DIGITAL CARDIAC PACER HAVING EXTERNALLY SELECTIBLE OPERATING PARAMETERS ABSTRACT OF THE DISCLOSURE An implantable cardiac pacer is instructible to vary the stimulation pulse interval, the stimulation pulse width, the stimulation pulse amplitude, the pacer sensitivity, the refractory period, and the mode (demand or asynchronous). A master parameter control circuit is provided to vary selected parameters of the heart pacer in accordance with an externally applied control signal. An external control unit produces two sequential series of pulses, the first series being an access code comprising at least one digital "0" state which must be detected by an access code detecting circuit within the master parameter control before the following parameter code will be accepted to vary the pacer parameters. The parameter code, generated subsequently to the access code, determines the selected set of pacer parameters, and can be selected from external controls upon the external control unit. The master parameter control circuit includes means for -1-recognizing the access code to enable the master parameter control circuit to only thereafter accept the selected parameter code. The entire parameter code must then be entirely received prior to changing the pacer parameters. -2-

Abstract: LOCKING DEVICE FOR MINING MACHINE         TRIM CHAIN TAKE-UP     Abstract of the Invention.  An improved locking device for a trim chain take-up for mining machines in which the trim chain extends around the auger and the auger support arms and is driven by the auger to cut clearance for the support arm.          The take, up is slidably mounted behind the auger support arm in guide means affixed to the machine frame.  When the take-up is moved away from the support arm to increase the tension on the chain, the locking device moves into the space developed between the take-up and support arm to prevent the take-up from backing off and reducing the chain tension.  The locking device comprises a plurality of thin spacers pivotably retained in a side-by-side stacked relationship on a rod mounted to the support arm.  The spacers are further disposed such that they are held in an inoperative position resting on the take-up until the take-up has moved past their respective positions whereupon they pivot about the rod into the operative position between the take-up and support arm.                             -1a-

Abstract: ABSTRACT OF THE DISCLOSURE A chemical oxygen generator using a chemical which generates oxygen by thermal reaction and an ignition device for the chemical is made by forming a continuous depression in a first plate, filling the plate depression with the chemical so as to completely fill the depression or to slightly overflow it, locating the ignition device in the depression adjacent one end thereof and covering the first plate with a second flat plate and pressing the two plates together to compact the chemical and deform the depression of the first plate.  The plates are subsequently secured together with a gas-tight connec-tion around the depression.  The generator advantageously comprises a continu-ous serpentine-like depression in one plate and has a closed end located in the plate and an open end extending to the edge of the plate which may be sealed by a foil when the two plates are pressed together.  The ignition de-vice is located adjacent the open end and it may be activated to cause the production of the oxygen from the open end successively to the closed end.

Abstract: ABSTRACT   A self-closing hinge assembly comprises first and second pivotally connected leaves, the second leaf having a hollow-cylindrical part mounted upon a hinge pin secured to the first leaf, and the hollow cylindrical part being mounted for limited axial and rotational movement relative to the hinge pin. A series of arcuate slots respectively engages with a series of projections, such projections extending either outwardly from the hinge pin or inwardly from the inner surface of the hollow cylindrical part. The slots are complementarily provided in the surface of the hinge pin or in the hollow cylindrical part, at least a part of each slot being helically formed to provide a camming action upon the projection associated there-with, in order to simultaneously axially move the second leaf member relative to the first leaf member upon relative rotational motion between the leaf members over the distance of travel of the projections along the helically formed portions of the slots.  Thus, the invention avoids the dis-advantages inherent in spring-loaded and hydraulically operated door closers, which tend to be either too light for many doors or too stiff and heavy.
