Abstract: MIRROR-TYPE BEAM STEERER HAVING A VIRTUAL PIVOT           ABSTRACT OF THE DISCLOSURE         A mirror-type beam steering apparatus employs at least one flexible mirror support member having, generally, the shape of the Greek letter lambda.  Each such member has a pair of flexible leg sections that slant toward one another and are truncated into an interconnecting section.  The diverging ends of the leg sections are fixed and an optical beam steering mirror is mounted to the interconnecting sec-tion.  With this arrangement, a "virtual pivot" occurs at the intersection of the leg section axis (although the legs themselves do not intersect), and torque components applied to deflect the mirror result in rotation of the mirror about the virtual pivot axis.  In preferred forms of the invention, the mirror's center of gravity is located on the virtual pivot axis, thereby reducing the inertial resistance to rotation and improving steerer performance.

Abstract: ABSTRACT OF THE DISCLOSURE           The present specification discloses a system for stock rotation of liquids, such as soft drink syrups, contained in collapsible bag-type reservoirs or replaceable packages.  More specifically, it relates to an automatic change-over device for automatically switching between a primary supply reservoir and a secondary supply reservoir in response to an empty con-dition of the primary reservoir.  The specification provides a device whereby two separate systems of single or multiple packages may be rotated automatically as they are empty, allow-ing for package changes to be made when time is available.  It discloses such an automatic change-over device having the necessary sensitivity for dispensing viscous liquids such as syrup, and for dispensing liquids disposed in flexible bag reservoirs.  The objects of the present invention are fulfilled in part by virtue of the inventor's discovery that flexible bag packages, when connected in circuit with a positive dis-placement dispensing pump, deflate when empty and create a pressure drop or vacuum in the dispensing circuit.  The change-over device consists of two internal check valves and a bypass valve.  Each check valve is connected by passages to separate bag package systems.  The bypass valve may be oriented to bypass the check valve connected to either of the bag systems and corresponding liquid circuits.  A bag circuit whose check valve is bypassed is considered to be the "primary" circuit since the pump will draw liquid from this circuit first.  The bag circuit which must flow through the check valve is known as the "secondary" circuit since the other circuit must be empty before the secondary circuit can be used.

Abstract: ABSTRACT :              In an X-ray examining device comprising a television chain and a (disc) image recording memory, the deflection signals Or the television pick-up tube and a drive of the recording memory are synchronized via the power supply mains, When the high voltage gene-rator is switched on, inductive loading of the power supply mains occurs. Consequently, the resultant phase shifts cause errors in the synchronization. This gives rise to the appea-rance of artefacts in a monitor image formed from the recording via the memory. Uncoupling of the synchronization from the power supply mains between an instant some time before and an instant some time after the switching on respectively off of the high voltage generator prevents the undesired recording errors.                             - i1 -

Abstract: DISC BRAKE AND MOUNTING THEREFOR  ABSTRACT OF THE DISCLOSURE         A disc brake includes a frame which carries a pair of friction elements on opposite sides of a rotor.  Support means fixedly secured to an axle housing cooperates with the frame to permit sliding axial movement and pivoting of the frame relative to the support means.  A pair of recesses on the support means receive flange portions of the frame and form clearances at the connection between the frame and support means.  Edges on the frame define guides for slidingly carrying the pair of friction elements and recesses on the friction elements fit over the guide for mounting the elements thereon.  Moreover, a clearance at the connection between the elements and frame permits the elements to easily slide relative to the frame and pivot relative thereto.  A spring member disposed between the support means and frame biases the frame to pivot relative to the support means to engage the friction elements with the rotor.  Adjustment means between the frame and one of the friction elements rotate relative to the frame to limit retraction of the friction elements away from the rotor. The spring member includes a portion releasably engaging the adjustment means to fix the position of the friction elements relative to the rotor.

Abstract: ABSTRACT OF THE DISCLOSURE   Process for pyrolysis of polymeric organic compounds to remove or retrieve them from objects or materials that are substantially unaffected by the applied heat. The steps include heating in a first vacuum chamber to render flowable such polymers as are fusible at a temperature below that at which appreciable degrad-ation is initiated. The fused polymer drops by free fall from the first chamber to a second vacuum chamber in space communicating relation therewith but maintained at a substantially lower temp-erature, where the polymer resolidifies. Upon further heating, polymer remaining in the first chamber is volatilized and withdrawn from the chamber to a water mist scrubber where it is largely trapped.  Remaining vapors in the scrubber are drawn through a vapor separator to a vent stack.  After the combustible volatiles are removed from the first chamber, air is admitted into the chamber to oxidize any residual carbon ash, leaving only the inorganic residue which is easily removable from the objects or materials that were not affected by the pyrolysis action.
