Abstract: IMPROVED PROCESS FOR MAKING DIAMOND                AND CUBIC BORON NITRIDE COMPACTS                  ABSTRACT OF THE DISCLOSURE         The high pressure/high temperature (HP/HT) process for making diamond or CBN compacts has been modified by placing partitions within the crystal mass before HP/HT processing.  Pliable metal shapes are placed in a honey-comb pattern within a shield metal sleeve and a shield metal cup.  The abrasive crystals within one set of the tubes and outside another set of the tubes is sintered, and a compact containing the tubes embedded therein results.  This compact can be acid leached to give a plurality of small compacts which need little if any additional shaping.  The partitions can also be left intact as chip arresters.

Abstract: LIQUID COOLING SYSTEM FOR ELECTRICAL APPARATUS          ABSTRACT OF THE DISCLOSURE           A liquid cooling system for electrical apparatus, particular semiconductor stacks, has a reservoir and a lower and an upper header communicating with the reservoir.  A plurality of arms connect the lower and upper header and the arms communicate with the stacks to conduct heat away from the semiconductors.  The lower header slopes upwardly in a direction away from the reservoir and the upper header slopes upwardly in a direction towards the reservoir to reduce the occurrrence of vapour locks. A pump circulates a cooling liquid from the reservoir through the lower header, the arms and the upper header to the reservoir.  A vacuum pump is connected to the upper part of the reservoir above the level of the cooling liquid to place the cooling system under reduced pressure so that any leaks which develop permit entry of air rather than outward leakage of liquid.  An alarm is triggered with abnormal running of the vacuum pump indicating a leak.  An alarm or shut down may also be triggered by a loss of the reduced pressure.

Abstract: B 229 (R) Abstract of the disclosure The invention pertains to coloured aqueous alkalimetal-hypochlorite compositions which are suitable for bleach-ing purposes. By inclusion in such compositions of a halogenated metalphthalocyanine pigment having from 6 to 16 halogen atoms per molecule of phthalocyanine, the colour remains stable much longer than when a metal-phthalocyanine is used having from O to 6 halogen atoms, at an alkalimetalhypochlorite level of 5-15% by weight. Inclusion of a metal complexing agent improves the chemical stability of the coloured composition. A pre-ferred embodiment is a coloured thickened alkalimetal-hypochlorite composition.

Abstract: ABSTRACT            The invention concerns a device for lifting objects, such as logs, from the ground. A substantially L-shaped lever has a shorter leg (2) and a longer leg (3). The end of the shorter leg (2) constitutes a ground support (11), about which the lever is singable at manual actuation of the end (8) of the longer leg (3). Upon such swinging a pivotable hook means (5,6) engages an object (7), which is lifted from the ground. A support (13,14) being extensible in the direction of the longer leg (3,9) is arranged to keep the lever and therewith the object in the raised posi-lion. The support is arrest able relative to the longer leg.

Abstract: HITCH CONTROL SYSTEM                   Abstract of the Disclosure A tractor includes a hitch for pulling a ground-engaging implement.  A hydraulic cylinder is extendable and retractable to lower and raise the implement.  A control system senses operating parameters, including wheel slip, engine speed, draft force and implement or rockshaft position.  Error signals derived from the sensed wheel slip, engine speed and draft force are combined into a composite or combined error signal.  The larger of the combined error signal, or a separately determined position error signal, is selected and converted to a pulsewidth modulated valve control signal which is applied to a control valve which then actuates the cylinder to move the implement to reduce the magnitude of the selected error signal.

Abstract: ABSTRACT OF THE DISCLOSURE     A plug assembly for use in a thermal-medium passage in a unit curtain wall, for example, comprises a circular gasket seat having a central cylinder with an annular elastomeric gasket placed on the gasket seat around the central cylinder, and a sleeve fitted over the central cylinder and fastened thereto by a fastener such as a hexagonal socket head cap screw threaded through a bottom of the sleeve axially into the central cylinder.  When the plug assembly is to be put in the thermal-medium passage, the plug assembly is inserted into the passage with the fastener slightly loosened.  After the plug assembly has been pushed to a desired position in the passage, the fastener is tightened by a tightening tool until the annular elastomeric gasket is resiliently squeezed between the sleeve and the gasket seat radially outwardly against an inner circumferential wall of the passage.  A heat-transporting medium such as hot water can be prevented by the annular elastomeric gasket from flowing through the passage.  The plug assembly is retained in position by a setscrew threaded through a passage wall against the sleeve.

Abstract: Abstract of Disclosure A dividing knife means for a saw machine, consisting of at least one dividing knife     located in the saw machine after the sawing blade    , as viewed in the sawing direction of the log  , keep-ing the saw cut open. The dividing knife     is a flange rotating about its axis     and of which a segment acts as a part spreading the saw cut. Therefore, the rotation of the dividing knife reduces the friction arising by the contact of the log and the dividing knife. It has specifically been a problem in connection with fixed dividing knives of prior art that the dividing knife cannot be made very thick because, acting as a fixed wedge, it impedes the progress of the log through the machine.

Abstract: ABSTRACT OF THE DISCLOSURE         At least two exhaust holes are formed in an atomizing nozzle of an apparatus for spraying the air-water mist for cooling which is used in continuous metal casting equipment.  The respective spraying mist streams from the exhaust holes cross each other before they reach the surface of a cast strand and are diffused forwardly due to the influence of the kinetic energy which serves in the spraying direction after they crossed, so that they suf-ficiently enter the region between the surfaces of guide rollers and cast strand, thereby directly spraying the air-water mist over the almost whole region of the surface of the cast strand.  In addition, a header is disposed in parallel to the guide rollers and a plurality of water branching pipes are attached in a line to the header in the longitudinal direction thereof.  The inner diameter of these water branching pipes are set to be sequentially smaller toward the lower stage.  The back pressures of the atomizing nozzles are reduced by causing the pressure losses in the water branching pipes coupled to the atomizing nozzles, thereby spraying the uniform flow rate of the water from each water branching pipe.

Abstract: ABSTRACT        A wire is wound into a coil form from a wrapping mechanism either onto a conventional reel or onto a core of a reelless coil with one twist per convolution.  Upon the subsequent removal from the reel or reelless coil in an at rest position, by utilizing a wire dispensing apparatus having a flying pick-up arm over the side of the coil, each convolution of the removed wire possesses zero twist.          Because the core of the reelless coil continually supports the coil until it is unwound, snags and tangles are substantially minimized during the removal of the wire and a twist-free substantially snag-free wire product is provided.
