Abstract: IMPROVED GEAR PUMP WITH FORCED  LUBRICATION OF SHAFT BEARINGS                  Abstract of the Disclosure An improved gear pump includes seal plates having lubrication channels communicating between the low pressure side of the zone where the gear teeth intermesh and the shaft bearings.  Lubricant flow is directed first through one bearing on one side of the pump and then back through the other bearing on that side to the pump inlet chamber, Placement of the lubrication channels on the low pressure side of the pump where the volume between intermeshing teeth is increasing ensures that flow reversals in the bearings and lubricant aeration are avoided; and renders bearing flow rate less sensitive to pressure so that relatively large flow channels may be used in the wear plate.

Abstract: ABSTRACT OF THE DISCLOSURE:           Apparatus for adding emulsifier to a fluid comprises a conduit for carrying the flow of fluid, with a nozzle portion or restriction in the conduit, and a tube extending into the region of the restriction, to supply emulsifier into the restriction region.  A valve is disposed in the conduit so as to be responsive to the flow of fluid, displacement of the valve member resulting in displacing the tube thereby to render the displacement of the tube dependent on the flow rate of the fluid through the conduit.  The conicity and diameter of the nozzle are adapted to the flow rate of the fluid in the conduit.

Abstract: Abstract A method and means are disclosed for use in a press whereby a sole and an upwardly projecting portion thereof, for instance, such as is used in many athletic type shoes, are attached adhesively to a shoe. An elastically deformable pad mounted in a relatively rigid support is recessed closely to fit the sole therein and has a wall overlying the projecting portion of the sole, the pad also having walls sloping toward the tread surface of the sole and inwardly of the pad. Sloping surfaces of the support engage external walls of the pad positioned thereon so that, when the support and pad are assembled in the press and the latter operated to cause the shoe to deform the pad, the heightwise projecting portion of the sole will be pressed against the upper of the shoe.

Abstract: ABSTRACT:            Colour television display tube of the shadow mask type with phosphor lines. In connection with the unequal centre distances between the central electron spot and the two outermost electron spots of a triplet as a result of the properties of the deflection coils, the width of the phosphor lines is chosen to be so that the electron spots in the case of mislanding simultaneously cross the edge of the phosphor lines. As a result of this the "white-remains-white" effect is obtained. The intermediate spaces between the phosphor lines of a triplet are preferably equal, which facilitates the inspection of the screens during the manufacture.

Abstract: Abstract of the Disclosure A metal test piece is disposed in a cell filled with a test solution.  The metal test piece is electri-cally charged instantaneously through a counter electrode so as to have a few millivolts polarization potential ?t.  The charge consumed by the corrosion reaction of the test piece is measured by a potential recorder in the form of a variation of the polarization potential ?t with respect to time t.  The measured (?t-t) relation is analyzed to obtain the polarization resistance Rp of the metal test piece.  After the poten-tial of the metal test piece returns to its natural potential Ecorr, the test piece is charged again until its polarization potential ?t rises to 50 millivolts or more, and the (?t-t) relation is measured in the same way as mentioned above. Based on this relation, the Tafel slop .beta.a of the anodic reaction is obtained.  After the potential of the metal test piece-has returned to its natural potential Ecorr, the test piece is so charged fro the third time as to have its polarization potential ?t lowered to -50 millivolts or less, and the (?t-t) relation is measured.  This relation is analyzed to obtain the Tafel slope .beta.c of the cathodic reaction.          Based on the polarization resistance Rp, Tafel slopes .beta.a and .beta.c, the corrosion current density Icorr is obtained, from which the density corrosion rate V is calculated.

Abstract: Form 233 TAMPERPROOF CLOSURE MEMBER     ABSTRACT OF THE DISCLOSURE             A tamperproof closure member adapted for press-on or snap-fit assembly over the neck of a container and carrying a tamper-indicating sleeve which must be irreparably separated therefrom in order to accommodate manual removal of the closure member from the neck of the container. The closure member comprises an endwall carrying downwardly depending retaining means adapted for snug-fitting, press-on, removable assembly of the closure member on the container neck.  In order to manually remove the closure member from the container neck, the endwall is structured to extend laterally outward beyond the retaining means and to provide an overhang presenting a bearing surface against which axially directed manual force for removal of the closure member necessarily must be exerted.  Manual accessibility to the bearing surface is, however, restricted by a tamper-indicating sleeve depending from the outer reaches of the endwall overhang and enclosing the bearing surface within the interior confines thereof to thereby isolate the bearing surface from manual accessibility required for removal of the closure member from the container.  The tamper-indicating sleeve is preferably interconnected to the endwall by means of a selectively weakened web section along which the sleeve is adapted to be irreparably torn or severed from the endwall as a necessary prerequisite to access to the bearing surface for removal of the closure member from the container neck.  To facilitate manual grasping and tearing of the tamper-indicating sleeve preparatory to removal of the closure member at least one tear groove or slit is provided which leads between the lower extremity of the sleeve and the selectively weakened web section. Press-on assembly of the closure member on the container neck is preferably attained by a snap-fit provided by the retaining means.     Form 233 To this end an inwardly directed retaining bead is provided which is adapted to engage the container neck in snug, snap-fit relationship.  The closure member is structured in such manner that the press-on and tamperproof features may be optionally incorporated into either a one-piece member, such as a snap cap, or a two-piece lid and ring assembly.

Abstract: Abstract of the Invention An improved fast-recovery circuit for ECG amplifiers and the like.  The fast-recovery circuit includes threshold responsive circuitry connected in parallel with part of the resistance associated with the intergrator in a feedback circuit of the amplifier.  The threshold responsive circuitry operates to increase feedback frequency response of the integrator when the normally low frequency output signal of the amplifier exceeds a certain threshold.  The improved circuit prevents the threshold circuitry from responding to pulses or excursions in the output signal of a relatively higher frequency content and which exceed the amplitude threshold for less than a predetermined interval, as for instance caused by pacer spikes, large QRS complexes and the like.  Preferably, the improved threshold responsive means comprises transistor means connected across the integrator's resistance and having capacitance means across the base-omitter circuit thereof for inhibiting response to certain short duration signals.

Abstract: Abstract of the Disclosure A noise reduction system for improving the S/N ratio of a color television video signal is described.  A frame portion of the video signal is stored in a memory and a fraction of this frame portion is added to a fraction of an immediately following second frame portion.  The signal level difference between the first and second frames determines the fractions to be added.  The outcome is that with higher level signals less noise reduc-tion is attempted than with lower level signals.  The system also has a frequency dependent equalizer for attenuating the high frequency components of a difference signal representing the difference between two frame portion signals.  The effect of this is to affect the high frequency components more than lower frequencies and this is beneficial because noise tends to be high frequency.
