Abstract: ABSTRACT OF THE DISCLOSURE        This invention relates to soldering irons, particularly to soldering irons for soldering wires into a multicore connec-tor.  According to the prior art, each wire is hand soldered into corresponding metal lined channels in the connector.  The wire coverings are stripped individually, and the wires are applied and soldered individually with a conventional soldering iron to a metal liner in the connector.  In another method, solder is applied to the wires and to the metal lines.  The wires are then inserted into the metal liners and each wire is soldered individually to its encompassing liner by melting the previously applied solder with a conventional soldering iron.          Recently, a wire positioning device has been developed which automatically cuts, strips, and positions the wires in their metal liners.  However, each wire must still be individually hand soldered.  The present invention provides a soldering iron in the form of a heat conducting plate having a plurality of projections at one end.  The projections are spaced to corres-pond to the spacing of the metal liners in the connector.  The sides of each projection converge towards its tip and are plated to resist oxidation and to be easily wetted by the solder.  The tips of the projections can be positioned within the channels in the connector with their converging sides contacting respec-tive edges of the metal liner.  In such position, heat can be conducted by the iron to solder wires positioned in the metal liners.

Abstract: ABSTRACT OF THE DISCLOSURE       A friction hoist has two or three friction wheels and each friction wheel carries a rope.  The ropes support a pair of counter balanced conveyances.  In one form of the invention having two friction wheels, one friction wheel is fixed to a common shaft and a motor rotates the common shaft to drive the wheel.  The other friction wheel is an idler wheel mounted adjacent the driven wheel and free to rotate on the common shaft.  Because one wheel is free to rotate it can make adjustments tending to equalize differential winding tension in the ropes.  A braking material is fixed to one of the friction wheels on the facing adjacent rim portions.  A braking assembly has a braking device adjacent each outwardly directed rim face.  A braking control actuates the braking devices causing the devices to engage the outwardly directed rim face of each friction wheel.  This engagement of the braking devices with the outwardly directed rim faces provides a braking action for each friction wheel and also urges the friction wheels towards one another into engagement with the braking material between adjacent facing rim portions tending to lock the two friction wheels together.  If one of the ropes should break, the conveyances are still supported by the other rope and the total braking forces on both the friction wheels are available for the unbroken rope.

Abstract: ABSTRACT OF THE DISCLOSURE         A corner key for securing channel members to from a frame, such as a gate frame which consists of two substantially identical mating members.  Each of the members is in the form of two identical sections joined substantially at right angles to each other.  There is at least one transverse groove on the face of each section which will mate with the other member so that when the mating faces of the identical members of the key are placed face to face apertures are provided in the corner key. These apertures are threaded to receive fastening means which tend to wedge the members apart thus creating a tighter fit in the channel member.  The transverse grooves in mating faces provide threaded apertures due to the fact that one groove of one section has a thread which is one half turn ahead of the thread in the other section so that mating threaded grooves provide the threaded aperture.  Longitudinally extending grooves are also provided in the mating faces so as to form longitudinal bores to receive hinge pins.

Abstract: ABSTRACT OF THE DISCLOSURE         DL-leupeptins have been known to be produced by leupeptins-producing organisms and only L-leupeptins have bioactivity.  This invention provides the processes for production of L-leupeptins in high yield and for its extraction without racemization.          L-leupeptins may be efficiently produced by inoculating a leupeptins-producing strain of Streptomyces into a medium containing nutrient sources and aerobically cultivating under the condition of pH 5.0 to 7Ø  Pro-duction of L-leupeptins is markedly increased by adding to the medium each 0.5 to 1.25% (wt/vol) of L-leueine, L-arginine (as hydrochloride), and glycine, and is further increased by adding to the medium 0.05 to 0.3% (wt/vol) of at least one of the yeast extract, casein hydrolyzate, and ribonucleic acids, in addition to the above amino acids.  Efficient separation of L-leupeptins of acceptable purity from the cultured broth can be effected by use of a nonionic adsorbent resin, wherein the pH is controlled always to be 7.0 or lower.  L-leupeptins thus obtained inhibit plasmin, tripsin, cathepsin B and papain, and the ointment containing L-leupeptins have been confirmed to be effective in treatment of inflammation, ulceration and burn of skin surface, erythemstosis, skin transplantation, etc.
