Abstract: Abstract An electric water heater of the "instantaneous" type heats the water immediately before use as the water flows through a closed small volume container having a water inlet and a water outlet.  An electric high wattage immersion heating element in the container is in circuit with a protective thermal cut-out device mounted on the exterior surface of the container.  The heating element has a helically coiled portion with a generally U-shaped portion extending therefrom into thermal contact with a portion of the interior wall of the container directly confront-ing the thermal cut-out device.  The helically coiled portion is positioned between the water inlet and the confronting wall portion and the water inlet is so positioned that the water moves in an unbaffled manner within the helically coiled portion toward the confronting wall portion thereby preventing "nuisance tripping" of the thermal cut-out.

Abstract: ABSTRACT A keyless, mechanical lock is described in which a correctly operated sequence of push buttons causes unlocking.  Unlike known devices of this type the required force exerted on the push buttons does not increase as the operator goes through the correct sequence so that the code cannot be deduced by feeling this increased force.  The device involves the use of two position inserts having cutouts  and in functional connection, respectively, with the push buttons. These inserts in the coded arrangement block the shifting of a rack when in a neutral position.  The inserts allow the shifting of the rack in the cutouts in the position displaced by a pushbutton.  The inserts in non-coded arrangement allow shifting of the rack in the cutouts when in neutral position and they block the shifting in the position displaced by the corresponding button.

Abstract: METHOD AND APPARATUS FOR MEASURING IN   SITU DENSITY AND FABRIC OF SOILS          ABSTRACT OF THE DISCLOSURE         A method and implementing apparatus for measuring in situ the electrical capacitance and resistance of soils and determining therefrom the density and fabric thereof. The apparatus includes a self-contained probe adapted to be driven into the soil to be measured  The probe has a soil sensor element and a measuring circuit such as a capacitance and resistance bridge.  The measuring circuit employs radio-frequency current to enable direct measurement at the probe of the resistance and capacitance of the soil sample and of the pore liquid.  A remote indicator and control unit in communi-cation with the probe is provided with indicators such as meters or displays which provide direct readout of measured resistance and capacitance, and which may also enable the bridge in the probe to become balanced.  Alternatively, the probe may include a computer for automatically balancing the bridge and calculating critical soil properties.  The apparatus can automatically register such engineering properties as density, porosity, friction angle, elastic and secant modulus, coefficient of dynamic settlement, stress ratio required to cause lique-faction, and permeability coefficient.  The probe and measuring equipment can, alternatively, be manually balanced and the engineering properties and related properties can be hand calculated.  The concept outlined and apparatus can be extended or modified for a wide variety of other uses also.

Abstract: APPARATUS AND METHOD FOR CONTINUOUS CASTING OF METALLIC STRANDS AT EXCEPTIONALLY HIGH SPEEDS          USING OSCILLATING MOLD ASSEMBLY Abstract of the Disclosure An oscillating cooled mold assembly for the continuous, high-speed casting of metallic strands, especially upcasting strands of copper alloys such as brass, has a hollow die in fluid communication with a melt typically held in a casting furnace.  A coolerbody surrounds the die in a tight-fitting relationship to form a solidification front in the melt as it advances through the casting zone of the die.  During assembly, the die is preferably slip fit in the coolerbody.  A shoulder on the die engages a lower face of the coolerbody and, together with a small irregularity on the upper coolerbody wall, prevents any axial movement of the die before it thermally expands against the coolerbody.  An insulating member located between the die and the coolerbody and below the solidification front fixes the location of the front within a dimensionally uniform area of the die. The insulating member is preferably a ring of a material such as cast silica that has a low coefficient of thermal expansion, a low porosity, and is highly resistant to thermal shock.  The insulating member also preferably creates a steep longitudinal temperature gradient at its upper end to promote a high cooling rate over a relatively short casting zone.  An insulating hat encloses the coolerbody, allowing it to be immersed in the melt and preferably deeply immersed to a level above the casting zone.          The strand or rod formed from the solidified melt is pulled through the die while the mold oscillates in a direction sub-stantially parallel to the direction of travel of the rod.

Abstract: Abstract of the Disclosure A valve for use under severe throttling conditions, includes a housing with fluid inlet and outlet passages communicating with a chamber inside the housing.  An abrasive-resistant throttling tube in fluid communication with the inlet passage projects into the chamber.  Also, an abrasive resistant  throttling plug is movably positioned inside the housing so that is  can be moved between a first position wherein is end is spaced from the mouth of the throttling tube and a second position wherein is obstructs the mouth of the throttling tube.  As mating surfaces of the plug and tube are eroded away by fluid flowing through the valve, the plug is advanced further and further toward the throttling tube so that unabraded surfaces of the plug and tube are presented to one another whereby maximum fluid throttling is achieved despite such wear.
