Abstract: Abstract of the Disclosure A device for crushing sinter and other material of like consistency is disclosed wherein the flow sinter material is deployed against an impact table which directs the sinter material downward onto a series of vertically disposed discs fixed to a common means of rotation.  The common means of rotation intersects each disc through its central axis.  Adjacent to the discs and parallel to the common means of rotation is positioned a shaft upon which are mounted crusher means arranged to intersect and pass between the discs.   As sinter is directed downward onto the discs, the crusher means rotates and forces the sinter between the discs, thus crushing it.  Heat buildup in the discs is controlled by a means of cooling which impinges on the discs.

Abstract: ABSTRACT OF THE DISCLOSURE           A series voltage regulator for producing a regu-lated direct output voltage from a direct input voltage that is subject to variations such as gradually increasing with time upon application of source voltage, with first and second transistors of opposite polarity where the col-lector emitter path of the first transistor is in series relation between the input and output terminals and the emitter-collector path of the second transistor is in series relation between the input terminal and the base electrode of the first transistor A voltage limiter such as a zener diode is connected between the base of the second transistor and a common input-output terminal. As source voltage increases from zero, the first transistor remains off until it is supplied base drive, which occurs only after the second transistor becomes conductive The second tran-sistor will conduct when the output voltage exceeds the sum of the second transistor's base emitter voltage drop and the voltage drop of the zener diode.  Saturation of the second transistor will cause the regulator to produce a steady out-put equal to the sum of the voltage drops of the zener diode and the base collector junction of the second transistor, minus the voltage drop of the base emitter junction of the first transistor.

Abstract: ABSTRACT            The present invention provides a pressure operated electrical switch and an alarm system using the switch.  The switch is constructed such that a force is applied to a pressure plate in the switch and once the load is reduced below a predetermined value the pressure plate will move under spring influence to close/open a microswitch or electrical contact means.  The invention has particular application as an alarm system for use in hospitals and nursing homes.  The normal force applied to the pressure plate is the load on the leg of a hospital bed when occupied.  If the bed occupant gets out of the bed  the load on the pressure plate is reduced below the predetermined value and the consequent movement of the pressure plate opens/closes the switch means to actuate the alarm.

Abstract: "MOUSE SERUM"     ABRIDGEMENT (ABSTRACT) In the analysis of liquids, particularly biological liquids such as serum or urine, there is used as a reagent mouse serum or a component of mouse serum.  The component has the ability to combine with antibody antigen complexes (but not free antibody or antigen) and to combine with IgG and IgM.  It differs markedly from human Ciq in that it remains active at high pH and in the presence of certain substances known to destroy human Ciq.  It is a very broadly applicable reagent in immunoassays, and particularly useful in techniques involving agglutination at latex particles.

Abstract: WHOLE TREE REDUCING APPARATUS              ABSTRACT OF THE DISCLOSURE             An apparatus for reducing whole trees having attached limbs and branches to chips wherein a power driven disc chipper is mounted on a frame and a tree or brush feeding and conditioning mechanism is driven at a coordinated feeding speed for feeding trees and tree parts into the chipper while folding projecting limbs and branches inwardly toward the trunk.  A pair of power driven feed rolls, mounted for rotation about generally horizontal axes above and below a feed path, are supported for both coordinated generally vertical movement relative to the frame and for relative vertical movement, and power actuated means are provided for selectively varying the vertical spacing between the pair of feed rolls.  The power actuated means are so arranged that when a squeezing action is applied, as to crush vertically projecting limbs, the upward force exerted by the lower roll exceeds the downward force exerted by the upper roll to reduce the frictional force exerted by any obstructing tree parts on the support platform.

Abstract: Abstract of the Disclosure A telephone central office switching network and a basic switching element utilized therein is disclosed herein.  The basic switch element has the capability of reflecting traffic entering any of the inlets thereto back to any other traffic inlet and the capability of connecting any of the inlets thereto to any of the outlets therefrom.  The basic switch is implemented in the network in a quasi-folded configuration in which the outlet from a switching stage is never connected to the same or a lower tier stage but rather is always connected to a higher order switching stage such that the outlets of the switching stages are progressively connected in a multistage configuration from the terminal stage into the folding point in increasing order, thereby enabling the outlets of the highest order stages to be used as reflection ports while simultaneously remaining available for connection to higher order switching stages without the necessity of recabling.  A continuously expandable switching network is thus provided wherein incoming traffic penetrates the network only to the decree necessary to complete the required signal connection and is implementable either in space division configuration, time division configuration or any combination thereof, and utilizing either analog or digital encoding techniques.

Abstract: TUNING APPARATUS                ABSTRACT OF THE DISCLOSURE  .           Tuning apparatus which is tunable to different broadcast frequencies and including a scale provided with indicia correspond-ing to such broadcast frequencies and a pointer movable across the scale to indicate the particular broadcast frequency to which the tuning apparatus is tuned.  The pointer is supported by a movable support which is guided by a guide shaft.  A plurality of markers are slidably guided along at least one guide rail and are individually settable to desired locations adjacent the scale, thereby representing particular broadcast frequencies to which the tuning apparatus is tunable.  A key also is slidable along the guide shaft with the movable support, the Key being selectively operative to engage a desired one of the markers to move the en-gaged marker therewith as the support is moved, whereby the marker is set to a desired position by reason of its engagement with the key.  Tuning circuitry having a controllable oscillator for gen-erating an oscillating signal whose frequency is variable and determinative of the broadcast frequency to which the tuning apparatus is tuned is enabled to produce an output representing received information when the movable support is moved to an aligned position with a respective one of the markers.  Thus, the tuning apparatus can be rapidly tuned to any preset broadcast frequency as represented by the particular marker with which the pointer is aligned.
