Abstract: LEAK DETECTION SYSTEM FOR  SUBTERRANEAN PIPELINES        ABSTRACT OF THE DISCLOSURE          A pipeline leakage detection and location system for detecting product leakage from, and the location of, a leak in a pipeline which comprises a retainer sleeve surrounding and pro-tecting said pipeline.  Collars are mounted in spaced positions along the pipeline forming, with the sleeve, a plurality of dis-crete segments from which leakage may be detected.  A spigot is connected to each segment including a reservoir.  A first hollow arm communicates with the interior of a segment and provides an inlet to the spigot.  A second hollow arm connects to a surface test point, and a third hollow arm is connected to a gathering pipe which is adapted to collect overflow of the leaking product from a plurality of spigots.  Leaking product drains into a sensor reservoir in which will be detected the presence of the leaked pro-duct by signalling that a leak exists, the location of the leak and that there is leaked product in the spigot reservoir.

Abstract: ABSTRACT OF THE DISCLOSURE A TV signal scrambling method employs level compression of selected horizontal flyback sections to prevent synchronization at the receiver. Key signals are transmitted along with the TV signal to be used in descrambling the picture, and are generally superposed on the horizontal synchronizing signal portion. The key signal is encoded before transmission so as to prevent unauthorized tapping which might otherwise occur if the key signal was separated and analyzed.

Abstract: CONTROLLED FLOW RATE INTRAVENOUS APPARATUS EMPLOYING SHAPE-MEMORY FLOW-CONTROL ELEMENT             ABSTRACT A unitary disposable conduit extends from the intravenous reservoir along a gravity-flow path to the patient, and incorporates a valve block contain-ing an externally controlled flow-control valve.  An electronic controller monitors the drop rate in a drop chamber which is an integral part of the disposable conduit, compares this rate with an operator-selected rate, and controls the valve by varying the current in a shape-memory actuator element whose movements, caused by the resultant Joule heating, are coupled to the valve to propor-tionally vary the flow rate in the conduit.  The valve block is securely received within a recess in the controller, and is automatically coupled to the controller when inserted within this recess.  The shape-memory actuator element may be incorporated within the disposable valve block, or may form a part of the controller, with a simple mechanical coupling to transmit its movements to the valve.  The valve may be automatically or manually closed when the valve block is removed from the controller, or if power failure occurs.

The shear chamber contains a shearing device for shearing the skeleton into small pieces and for moving the pieces of the skeleton into a compaction chamber which is located adjacent to the  shear chamber.  The compaction chamber contains a compaction cylinder for compacting the pieces of the skeleton introduced thereinto.  A storage canister is located below the compaction chamber such that when the slide of the compaction chamber is opened, the compacted pieces of the skeleton may be pushed into  the  storage canister.  When the storage canister is filled, it may be remotely removed and replaced with an empty canister.

Abstract: Balanced Armature Type Relay ABSTRACT OF THE DISCLOSURE: __________________________ A balanced armature type relay includes a coil assembly(2)with a coil(20)and an ion core(21)extending through the coil (20), an armature assembly with a pair of frame-shaped upper and lower armatures(3, 4)disposed parallel to each other and so as to surround the coil(20), and a pair of contact units(6, 8) operated by the armature assembly. The coil(20) is covered with a molded portion(23) which has a pair of lateral studs(24)integrally formed with it, the studs(24)defining a horizontal axis about which the armature assembly is pivotal. High accuracy in the positional relation between the pole faces formed by extending ends of the iron core(21)and the respective ends of the armatures(3, 4)cooperating with the pole faces is achieved by the fact that both the pole faces provided on the iron core (21)and the studs(24)form part of the coil assembly which is formed as one common block.          At the same time, a very thin relay is obtained since the overall vertical dimension of the relay may be restricted to the height of the coil.

Abstract: Process for the preparation of a sweet wort from a cereal, in which previously mashed cereal flour is mixed with a hydrolyzing substance introducing enzymes to undergo a saccharification treatment. Before mashing, the cereal flour is subjected to a cooking-extrusion at a temperature above 100 DEG  C., by passage continuously in a screw-extrusion machine provided with heating means. The amount of water can be limited to that necessary for the bursting of the starch grain. The extruded cereal is then mashed and mixed with the hydrolyzing substance to undergo saccharification, and the latter can then be effected by infusion. The invention is especially applicable to the preparation of beer or of alcoholic beverages by fermentation of the sweet wort obtained.

Abstract: PRUVISION OF PLASTIC INSULATION UPON AN ELECTRICAL CONDUCTOR     Abstract of the Disclosure Providing plastic insulation on an electrical conductor in which the conductor, enclosed in an oversize tube, is passed through a fluid and through an annular crystal of a piezoelectric material immersed in the fluid.  During passage of tube and conductor, the crystal is subjected to electric current to cause alternating expansion and contraction of the crystal.  Pressure shockwaves are produced by this expansion and contraction and the shockwaves are focussed upon the pass line of the tube and conductor to cause localized inward deformations of the tube into engagement with the conductor to form spaced annular depressions in the tube.  In preferred arrangements, apparatus has an extruder immediately upstream of the crystal so that the plastic tube is in a heated and softened condition during its deformation. A focussing means is required in the apparatus for focussing shockwaves on the pass line.  In a practical arrangement, the focussing is provided by an annulus of wave transmitting material which has a concave inner surface facing the pass line.     - i -

Abstract: ABSTRACT OF THE DISCLOSURE   A distributor having electrodes made of a sintered body composed of a composite material such that the distributor can suppress radio noises to thereby prevent electric interference. The material for the electrodes, the sintered body, is composed of 45-90 mol% of zinc oxide and 55-10 mol% of ferrite, which can suppress radio noises generated between the electrodes due to spark discharging.  At the same time, the energy loss within such composite material is small and consumption of electrode can be restrained. Electrode durability is further improved by including bismuth oxide, man-ganese oxide and cobalt oxide in the electrode material.  An ignition plug and electric discharge machine can also advantageously use the electrodes composed of such materials.
