Abstract: ABSTRACT OF THE DISCLOSURE:           This invention is concerned with a sliding nozzle device for applying a predetermined sealing pressure between a stationary refractory plate and a sliding refractory plate of the sliding nozzle for achieving the complete regulation of pouring of molten metal from a ladle vessel.  A desired press means, which can be replaceable mounted on the sliding nozzle if desired, is provided for urgingly pressing the sliding plate toward the stationary plate without necessitating conventional manual force.  The sliding nozzle is advanta-geously shaped so as to allow mounting of the above press means thereon and to maintain the sealing pressure between the refractory plates during the operation of the sliding nozzle.

Abstract: LIQUID ABSORBING ASSEMBLY Abstract of the Disclosure An ink absorbing assembly has a first porous material disposed close to a paper against which ink jet droplets impact to print.  Ink from an ink mist, which is produced from the droplets striking the paper, is absorbed by the first porous material and then transferred to a second porous material, which is in contact with the first porous material and of a different porosity than the first porous material.  This enables the surface of the first porous material adjacent the paper in the print area to be relatively dry so as to not allow airborne particles to cling to this surface.  By making the porous material of smaller porosity relatively thick in comparison with the other porous material, a relatively large quantity of ink can be absorbed by the porous material of smaller porosity without the surface of the porous material adjacent the paper in the print area becoming wet before replacement is necessary.

Abstract: ABSTRACT OF THE DISCLOSURE     A system for providing a signal suitable for transmission by telephone equipment to indicate the duration of pulses produced by a heart pacer is disclosed.  The system includes a pickup for detecting pacer pulses and a switched circuit responsive to pulse duration for applying charge to a first capacitor.  During the inter-pulse period a second or reference capacitor is charged to a level corresponding to that of the first capacitor through a timed switching circuit, after which another timed switching circuit discharges the first capacitor to prepare it for receiving a sub_ sequent charge.  The potential accumulated upon the second capacitor is then used to operate an output stage pulse generator which controls the duration of an audio-frequency tone burst   The duration of this tone, or more precisely, the period of interruption of this tone provides a telephonically transmittable analog of pacer pulse width.

Abstract: Abstract of the Disclosure First and second windmill wheels are mounted on and non-rotatably connected by shaft means, which define a vertical axis.  Each of said windmill wheels has rigidly interconnected vanes, which are adapted to return opposite to the direction of the wind.  Said two windmill wheels define axially outermost flight circle planes which intersect at an acute angle.  The vanes of each of said windmill wheels are adapted to describe an orbital line, which is tangent to a corresponding orbital line described by the vanes of the other windmill wheel at an apex, which is disposed between said flight circle planes.  Control means are operable to move said windmill wheels relative to each thus to vary said angle when measured in a vertical plane that is at right angles to the direction of the wind.  Said vanes of each of said windmill wheels interdigitate with those of the other windmill wheel adjacent to said apex so that said vanes shelter each other from the wind as they return when said apex lies in said vertical plane.

Abstract: #4964                        .     METHOD AND APPARATUS FOR PROCESSING DROSS           ABSTRACT OF THE DISCLOSURE    The invention relates to the recovering of free metal en-trained in dross or skimmings obtained from melts of aluminum and aluminum based alloys wherein the dross has been partially prepared by prior art preparation processes.  The invention is directed to the cleaning and preparation of the dross by the more effective removal of substantial portions of the oxide coatings on the dross.  This results in the recovery of a sig-nificantly higher proportion of the free metal contained in the dross than is recovered using prior art cleaning and recovery processes.  The dross, as partially processed by prior art methods, is sequentially fed through selected mechanical rolling and milling stages so as to separate aluminum oxide dust and aluminum concentrates from one another.   The aluminum con-centrates may be utilized in conventional furnace recovery methods to produce aluminum ingot or may be further processed through selected stages to produce high quality aluminum pellets.

Abstract: DIGIAL OPERATE/RELEASE TIMER            Abstract of the Disclosure Operate/release timing circuits are employed to generate time delayed pulse signals employed, for example, in telecommunications signaling systems.  Pulse position and pulse width errors and other problems are resolved by employing a single digital counter and associated control logic elements.  Input signal pulse break, gap and the like immunity is achieved by controlling the counter to count up for a predetermined interval regardless of the presence or absence of the input pulse signal.  Once a valid input pulse has been detected and is terminated, a timer output change of state is delayed for a so-called release delay interval.  Once the pulse signal has terminated for a predetermined integrated interval, the counter is controlled to continue counting down until the initial condition is reached regardless of the presence or absence of the input pulse signal.
