Abstract: HAYLAGE/SILAGE MOISTURE TESTER            Abstract of the Disclosure A moisture tester is provided for testing a sample of feed of the silage, haylage, and like compressible variety.          The tester includes a chamber for receiving a feed sample.  A compressor piston compresses the feed sample in the chamber to a predetermined density to provide accurate, reliable, reproducible results.  The chamber comprises spaced electrodes constituting a capacitor such that the dielectric constant of the capacitor is modified in accordance with moisture within the feed sample.  A circuit functionally including the capacitor develops a signal in accordance with the moisture content of the sample.  A readout, responsive to the circuit signal, provides a visual indication of the feed sample moisture content.  A circuit trigger is automatically operated by the compression exerted upon the feed sample to start circuit operation and provide the feed sample moisture content readout.

Abstract: ABSTRACT OF THE DISCLOSURE Conventional orthodontic treatment is accomplished with metal bands provided with an attachment made to adapt to the teeth and is fixed to the teeth with cement, and metal wire is made to run through it to move the teeth. However, using this technique, it has been recognized that tremendous amounts of energy and skill as well as long periods of education are needed.  Also, such treatment not only causes discomfort to the patient, but also other problems such as decayed or decalcified teeth or peridontal disease result from food particles adhering to the teeth during the orthodontic treatment, and, moreover, costs rise enormously.  The present invention provides a method and means for manufacturing an orthodontic treating device by which a malocclusion can be treated simply by utilizing the elastic force of silicone resins as a functional force instead of the metal wire presently being employed, and since it is easily detachable, it does not render any discomfort to the patient, making it possible to accomplish the orthodontic treatment when used at bedtime and waking hours as needed.

Abstract: METHOD FOR MANUFACTURING MULTISECTION CABLE CORE WITH INTERMETALLIC COMPOUND-BASED SUPER-CONDUCTING COATING           ABSTRACT OF THE DISCLOSURE According to the invention, a barrier layer is applied onto the ends of each core blank prior to the formation of a superconducting layer.  The formation of the superconduct-ing layer is followed by a removal of the barrier layers from the core sections, whereupon the sections are welded toge-ther along the perimeter.  A superconducting layer is then produces by means of diffusion in the welding zones and the adjoining end portions of the sections stripped from the bar-rier layer, The proposed method makes the strength and super-conductivity of the welded joints equal to those of the core sections.

Both the mounting flange and the end plate have ports that communicate with the interior of the cylinder.  A piston is disposed in the hydraulic cylinder for longitudinal movement therein in response to the introduction through the ports of pressurized fluid.  The stem that carries the turbine meter extends longitudinally through the hydraulic cylinder and is secured to the piston.  First and second guide pins are secured to the upper end of the stem by a yoke and extend parallel to the stem.  The end plate at the second end of the hydraulic cylinder is provided with a flange having guide openings therein through which the guide pins pass.  The apparatus is operable in response to control signals in the form of a pressurized fluid to translate the stem to either insert the turbine meter to the proper location within the pipeline or to retract the turbine meter from the pipeline into the riser.

Abstract: ABSTRACT OF THE DISCLOSURE A method and device for testing tube leakage, more particularly in a moisture-separator reheat superheater, to  determine a tightness of separating walls between two flowing media which are separated from each other is disclosed.  A first medium, e.g. an inert gas, such as helium, is introduced into a first medium whereby a lack of tightness in the separating walls can be quantitatively measured by a mass spectrometer in a sample taken from the second medium.  In the event that the second medium consists of a number of phrases, the nongaseous phases can be separated out by first condensing and, if necessary, by freezing the sample prior to testing.  The test gas may furthermore be supplied to the second medium through a calibrated orifice to permit a determination of the extent of the tube leakage.

Abstract: REFRIGERATION SYSTEM FOR HEAT EXCHANGERS SUCH AS USED IN          ICE RINKS AND THE LIKE            ABSTRACT OF THE DISCLOSURE           Liquid refrigerant is pumped through the heat exchanger in the rink field or the like, on demand, and back to the evaporator.  Any vapor is pumped through the compressor to an externally situated air cooled condenser and back to the evaporator thus maintaining the liquid phase.          When the external condenser is in an ambient temperature, a predetermined amount below the temperature of the heat ex-changer, the compressor shuts off and the liquid refrigerant is circulated by a liquid pump directly through the conden-ser and back to the evaporator to cool down the liquid re-frigerant thus saving considerably on running costs inasmuch as the compressor is not used.
