Abstract: The invention refers to an electronic length measuring device by which elongated articles as for example planks (5) can be easily measured and the total cost of which can be easily calculated. The invention substantially comprises a measuring tape which can be pulled out from the gauging station (1), and at the free end of which an operating device (3) is arranged. The measuring tape (2) is provided with a number of detectable elements (11) arranged along the measuring tape (2) at equal distances from each other. The detectable elements (11) are detected by a detector (8) arranged in the gauging station (1), the signals of which are supplied to an electronic unit. The operating device (3) is furthermore provided with at least one switch (15) by means of which the operator is able to initiate the electronic unit (14) to accumulate measured length values to a memory (22). This memory (22) would be updated each time the switch (15) is manually activated and the value accumulated in the memory (22) is shown on a sum display (20). The electric signals thus generated in the operating device (3) are transmitted by nhe transmission elements (12,13) which for example can consist of electric conductors to the gauging station (1) and the electronic unit (14), said electric conductors being arranged in the measuring tape (2).

Abstract: Abstract of the Disclosure A hardware assembly for luggage and the like includes a latch pivotally supported on a luggage case and held in a closed position by engagement between catch elements on the latch and cooperating catch elements on a control member supported for movement along the case, the control member being biased in a direction to engage the catch elements.  A pivoted manual actuator associated with the latch engages the control member and is capable of moving the control member in a direction to disengage the catch elements to allow the latch to be opened, when the manual actuator is operated.  The catch elements serve as a safety catch to prevent the latch from being opened until the catch elements are disengaged.  The hardware assembly may further include a latching slide member coupled to the latch by a link member for movement with the latch, and for engaging a cooperable latch element on a second part of the case when the latch is in the closed position.  A combination lock may also be included for blocking movement of the control member necessary to open the latch.

Abstract: CHAIN SAW WITH CHAIN GUARD MEMBER          Abstract:     The present invention relates to a chain saw.          The saw includes a housing, a guide bar projecting from the housing, a cutting chain mounted to run on the guide bar in a closed loop and a motive unit carried by the housing coupled to the cutting chain.  The housing includes a portion forming a channel through which the cutting chain travels as it is propelled around the guide bar.  The housing also includes a chain guard member which is com-prised of a pin mounted on the housing portion.  The pin includes a shank portion which projects into the channel and is disposed between opposite ends of the loop and beneath the lower run of the loop of the cutting chain.          The pin projects transversely with respect to the plane of the loop through the probable trajectory followed by the cutting chain when the chain becomes disengaged from the guide bar during operation.  The chain guard member serves to catch or intercept the cutting chain and retard its movement to prevent it from striking an operator of the saw.

Abstract: ELECTRICAL CONNECTOR ASSEMBLY AND METHOD OF MANUFACTURE            ABSTRACT OF THE DISCLOSURE An electrical connector. assembly is presented wherein a cord attachment such as a plug or strain relief is mechanically anchored to an electrical cord. The anchoring is effected by a series of bridges integral with and connecting opposing sides of molded cord fitting, the bridges passing through and interlocking with the walls defining the series of holes formed in the cord.  The series of holes is punched or otherwise formed in the webbing of the electrical cord. As the fitting is molded over the perforated portion of. the cord, molding material fills the holes forming the bridges which constitute a positive mechanical bond for the electrical connector assembly.

Abstract: ABSTRACT OF THE DISCLOSURE    A method of treating salt water-in-oil dispersions comprises mixing with the dispersion a latex of a rubber having a high wet gel strength.  The incorporation of the latex into the dispersion causes exudation of water from the dispersion with resulting thickening.  If sufficient latex is used the dispersion may be transformed into a solid.  Suitable rubbers include natural rubber, polychloroprene rubber, butadiene acrylonitrile rubber, styrene butadiene rubber and poly (methyl methacrylate) graft natural rubber.     The tackiness of solids formed using for example a natural rubber latex can be reduced by using in addition to the natural rubber latex, a latex of a low or zero wet gel strength polymer e.g. PVC, poly (vinyl acetate) or polystyrene.  The effectiveness of the method of treatment may be improved by the use of a suitable compatible solvent e.g. toluene or a filler such as a clay filler.

Abstract: ABSTRACT OF THE DISCLOSURE Disclosed is a method of altering the zirconium 91  isotopic content of zirconium by raising a zirconium chelate ligand from a ground state to an activated state in the presence  of  a scavenger which  reacts with  the activated state but not with the ground state,  and per-mitting about 25 to about 75% of the zirconium chelate to react with the scavenger.  The reaction may be performed in a solution of the zirconium chelate ligand using water as a solvent.  Activation of the zirconium chelate may be accomplished by using light and having a wavelength of about 220 to about 350 nm or by heating to about 80 to about 100°C.

Abstract: ABSTRACT OF THE DISCLOSURE A deflection generator of a television receiver includes a trace switch that during normal mode of operation is switched at a deflection rate to generate scanning current in a deflection winding.  The deflection generator includes a retrace capacitance for forming a retrace resonant circuit with the deflection winding to produce a retrace pulse voltage.  A load circuit is coupled to the deflection generator and is energized by the retrace pulse voltage during normal operation.  A remote control circuit develops a remote ON-OFF command signal. A standby circuit is series coupled with the deflection generator and is responsive to a remote ON-OFF command signal for producing a substantially short circuited trace switch upon receipt of the OFF-state of the command signal. The retrace pulse voltage collapses and places the load circuit in a standby mode of operation.

Abstract: METHOD AND APPARATUS FOR LIQUID METAL COLLECTION FROM VAPOR USING MOLTEN POOL OF COLLECTING METAL            ABSTRACT OF THE DISCLOSURE       A metal vapor, such as can be produced by sublimation of crudely smelted lumps of the metal at high temperature, is led, at a high enough temperature and a low enough pressure for the condensation of the vapor not to take place, into the upstream end of a convergent-divergent nozzle, and then squirts out from this nozzle, being cooled down rapidly by adiabatic expansion in the nozzle to a low enough temperature for the condensation of the vapor to take place. The jet flow emitted from the downstream end of the convergent-divergent nozzle, which has been thus cooled, is led to the surface of a pool of molten collecting metal, either directly or via a jet flow decelerating device. The collecting metal in this collecting metal pool is the same kind of metal as the metal vapor which is to be collected. Thus the condensed metal vapor in the jet flow is entrained into the collecting metal pool in the liquid state. Apparatuses are also disclosed for performing these various methods.
