Abstract: DENSITY METER                     ABSTRACT OF THE DISCLOSURE      A device for taking air gap backscatter radiation measurements at a pair of predetermined distances from the surface of a material is disclosed.  The ratio of the first and second measurements are a function of the density of the material when one of the distances is sufficiently large that the measurement is dependent on the chemical content of the material but is independent of surface irregularities and density and when the second distance is greater than the average surface irregularity but sufficiently proximate to the material so that the measurement is independent of surface irregularties but is dependent on the density and the chemical content of the material.  The device includes a housing slidably supported between a pair of end plates, a carrying handle for the device and a source within the housing.  When the handle is in a first position, the source is disposed in a storage or "safe" position.  Rotation of the handle to a second position moves the source to a first "use" position, and rotation of the handle to a third pre-determined position also places the source in the use position and raises the housing with respect to the end plates.        Differential backscatter radiation measurements are taken while the device is in its two use positions.

Abstract: HOLD CONTROL FOR A KEY TELEPHONE SYSTEM     Abstract of the Disclosure To convert a multiple line, multiple telephone set installation into a key telephone system, a control unit is provided at each telephone set. The control unit includes a regulated power supply, a control circuit, pushbutton line select and hold switches, and indicator lights packaged in a compact assembly which can be readily attached to the base of a standard telephone set or mounted separately. Electrically controlled switching devices within each control circuit respond to the pushbutton line select switches to couple the telephone set to a selected one of the lines and automatically disconnect the set from the line when the call has been completed. An incoming ringing signal on any one of the telephone lines is detected by the control circuit and the ringing signal is automatically applied to the bell of the telephone set. A line on which a call is in progress may be placed in a hold condition by operating the hold select button which thereafter enables the telephone set to be coupled to another line, if desired, for receiving or placing another call. A conference call can be established by simultaneously operating the two or more line select switches which in turn cause the selected lines to be jointly connected to the telephone set. The indicator lights on each control unit respond to standard central office supervisory signals which appear on the telephone lines and which represent on-hook (idle), ringing and off-hook (busy) line conditions, and also respond to a special hold indicating signal which is applied to the line by the control unit during the hold condition. The control units of the various telephone sets operate solely in conjunction with the standard telephone lines that extend from the central office and no additional interphone wiring is required and no central control unit is needed.

Abstract: ABSTRACT OF THE DISCLOSURE       A metal disc saw has a frame carrying a slide upon which a saw blade is rotatably mounted.  The frame is pivotable and securable relative to a fixed workpiece stop.  The slide is horizontally movable away from a starting position to effect a cut on a workpiece.  In the starting position, the saw blade is on the opposite side of the workpiece stop to the workpiece.  The axis of the saw blade is above the workpiece and the direction of rotation of the saw blade is opposite to the direction of movement of the slide so that during cutting, the workpiece is urged against the stop.  This reduces vibration and wedging between the workpiece and the saw blade because the workpiece stop is rigidly secured to the workshop floor via a pillar relative to which the machine frame is pivotable.
