Title: Continuous controlled mixing of chips and - binder
Inventor: ENGELS K
Filed: 1970-12-23
Abstract: Continuous control of mixing of chips or fibres with binding agent is effected by volumetrically dosing the solids and binding agent into a mixer and subsequently checking final mixture by weighing. Dosing quantities are preferably small, e.g. 1/500 to 1/1000 of hourly production, so that vibrations in ascertained weight of chips or fibres dosed by volume, can be used as basis for adjusting dosing rates.

Abstract: A B S T R A C T     A process for the production of electroplated aluminium stock, such as strip or wire, comprises passing the stock continuously through a bath having a high dissolving power for aluminium oxide, such as strong aqueous sulphuric acid and phosphoric acid and subsequently through an electroplating bath, the first bath having a cathode electrode and the electroplating bath having an anode electrode so that the stock is anodic in the first bath.  The stock may pass through one or more intermediate non-electrolytic treatment stages, such as immersion tinning or zinoating.   It may also pass through one or more electrolytic pretreatment stages during its passage between the first bath and the electroplating bath.  In such pretreatment stages, such as the appli-cation of a bronze strike, there may be an anode electrode at the same potential as the anode in the electroplating bath.

Abstract: ABSTRACT OF DISCLOSURE           This invention relates to a method and apparatus for reproduc-ing operating conditions in induced flow devices, such as carbure-tors and the like, and more particularly to a system for reproduc-ing such operating conditions which may be used in testing systems designed to test induced flow devices.           In operation in such a test system, the apparatus of the present invention would cause a given air flow to flow through an induced flow device such as a carburetor, and then would cause the throttle plate of the carburetor to be rotated until the desired manifold vacuum in the carburetor is obtained, at which time the test of the carburetor could take place.  By providing a throttle drive controller to move the carburetor throttle at a speed which is proportional to the difference in the manifold vacuum actually present in the carburetor, and the desired manifold vacuum, a very rapid movement of the throttle plate between test points can be had, but at the same time ?=slow approach to the actual test point, to prevent overshoot, is accomplished.           A continuous monitoring of the difference between the manifold vacuum in the carburetor, and the desired manifold vacuum, is accom-plished by a continuous reading and comparing of electrical signals, in either a manual or computer controlled system, in which the two signals are first compared to determine which way the carburetor throttle must be moved to approach the desired test point, and then the actual difference between the two signals is computed to deter-mine how many additional pulses must be supplied to the stepping motor forming part of the carburetor throttle drive controller to control the drive as described above.           The operations reproducing system of the present invention works equally as well computer or manually controlled, or with sonic or subsonic air flow measuring devices.

Abstract: TENNIS RACKET                      Abstract of the Disclosure The tennis racket has a strung surface which is larger than the strung surface of a conventional racket, par-ticularly in regard to its dimension in a longitudinal direction from the frame tip toward the handle shaft of the racket.  The conventional length, weight, and balance which have proven nec-essary for good playing characteristics for all tennis rackets of the past have been maintained.  The racket has unexpectedly achieved increased strength and a combination of advantages in playing characteristics without resort to weights, springs, or other complications previously proposed.  The racket has a zone of high coefficient of restitution, much larger than that of conventional rackets, extending in a longitudinal direction from the region of the center of percussion to a point 1-1/4" from the throat of the racket, thereby taking maximum advantage of the location of the center of percussion of the racket.  The zone of high coefficient of restitution is also wider with respect to the corresponding zone on conventional rackets.

Abstract: Abstract of the Disclosure A cage unit for mounting a metal diaphragm in a nuclear valve.  Similar nuclear valves utilizing metal diaphragms to restrict leakage of fluid passing through the valve to atmos-phere have utilized welding of a metal diaphragm directly to the bonnet of the valve.  Welding of the metal diaphragm directly to the bonnet adversely affects the properties of the diaphragm, as well as rendering replacement of the diaphragm in the field upon breakage thereof quite difficult.  Further, welding of a diaphragm unit consisting of 8 to 12 very thin (.006-.008") discs requires special welding procedures, whereas welding of the cage unit to the bonnet can be performed in the field without requiring any special skills.  By utilizing a cage unit supporting the metal diaphragm, the cage unit itself is welded to the bonnet, the cage unit being replaceable in the field.  The cage unit comprises a pair of annular metal members situated on either side of the metal diaphragm which is squeezed therebetween.  An outer periphery of the metal diaphragm is welded to the pair of annular metal members to prevent leakage to atmosphere of liquids passing through the valve.
