Abstract: ABSTRACT OF THE DISCLOSURE       A pneumatic tyre and wheel rim assembly comprises a one-piece wheel rim having a well and a well filler, the well being in a position in which the well filler is required to serve as at least a part of the bead seat.  The well filler includes a band of resilient polymeric material in the base of the well and an overlying segmental filler comprising a plurality of segments of rigid material linked together or held together by an encircling band.  Contact between the segmental filler and the resilient band at the interface between them is rendered discontinuous by means of contouring of at least one of the contacting surfaces to allow for distortion to compensate for irregularities in the dimensions of the wheel rim.

Abstract: ABSTRACT OF THE DISCLOSURE            An intravenous infusion system combined with a venous pressure measuring instrument whereby the system is selectively capable of supplying fluid into the vein of a patient or of measuring his venous pressure without, however, exposing fluid in the system to the atmosphere and possible contamination.          The instrument includes a transparent chamber interposed be-tween an upstream line extending to the infusion fluid supply and a downstream line leading to the patient.  A collapsible bulb disposed within the chamber is vented to the atmosphere, the bulb collapsing only when its internal pressure is less than external fluid pressure.  In the infusion mode, supply fluid passing through the chamber is fed to the patient, the resultant fluid pressure in the chamber causing the normally-erect bulb to collapse.  In the venous pressure mode, the up-stream line is clamped to interrupt flow, the fluid pressure then exerted on the bulb being a function both of venous pres-sure and the height of the chamber relative to the heart, the higher the chamber the lower the pressure.  By elevating or lowering the chamber to a point at which fluid pressure therein is equal to atmospheric pressure, a balance or reference pressure level is established, this level being indicated by the sudden erection or collapse of the bulb, depending on whether the bulb is moving upward or downward.  Venous pressure is then deter-mined by measuring the height of the chamber at this level along a scale formed on the downstream line.

Abstract: Abstract of the Disclosure The invention relates to a method and apparatus for reclaiming particulate used activated carbon.  A vertical hollow column is provided with at least two horizontal, ver-tically separated electrodes, each being in the shape of a grille having holes large enough to allow the passage of the used active carbon particles therethrough.  The particles are continuously introduced into the top of the columns above the upper electrode so that the particles flow down through the electrodes.  A voltage is applied between the electrodes so that a current flows through the carbon particle mass located between the electrodes and the heating resulting therefrom causes desorption of adsorbed materials from the carbon particles. By making the current flow in the same direction as the particles in this manner, many of the disadvantages of the prior apparatus, in which the current and particles flow at right angles, are avoided.

Abstract: ABSTRACT OF THE DISCLOSURE Single sheets coated front and back with chemicals capable of reacting with one another to produce a colored mark are used to construct business forms such as envelopes and manifold sets.  The sheet has two fold lines allowing one end panel to be folded over the middle panel and allowing the other end panel, which may be a detachable receipt section to be folded over the first end panel.  The first end panel and the middle panel may constitute an envelope.  Upon application of pressure to the receipt section or to the top part of a manifold set the contacting coated back of the receipt section is forced into reactive contact with the coated front of the underlying panel to produce the colored  mark.  Thus, information applied to the outside receipt section can be duplicated on the underlying mating panel.

Abstract: TITLE PLATE MARKING APPARATUS              ABSTRACT OF THE DISCLOSURE            A vertical member is supported by a frame adjacent  a plurality of driven horizontally positioned rollers that support a plate to be marked.  A carriage is mounted for reciprocal movement on the vertical member. An extensible piston rod of a cylinder assembly is secured to the carriage, and the assembly is secured to the verti-cal member.  A driven shaft is rotatably supported by the carriage.  A marking wheel having marking elements is secured to the end of the shaft above the surface of the plate to be marked.  An electric motor on the carriage is connected by a belt drive to a single revolution clutch of the driven shaft.  Rotation of the shaft urges the marking elements into marking engagement with the surface of the plate to mark the plate.  After each actuation of the clutch the driven shaft is rotated to return the marking wheel to a position to permit the plate to pass unob-structed beneath the marking wheel.  During the plate marking operation the cylinder assembly exerts a downward force upon the carriage to maintain the marking wheel in marking position.  A second cylinder assembly is operable to laterally pivot the carriage to facilitate a change of marking elements on the marking wheel or marking wheels on the shaft.

Abstract: Abstract of the Disclosure Pulses from a reference oscillator are counted in a counter to provide a count output as a changeable digital value.          A ramp generator generates a saw-tooth wave which changes in synchronism with the count output.  A comparison voltage generator, which may typically comprise a variable resistor, is also pro-vided.  A load enable signal generator compares the saw-tooth wave and the comparison voltage set in the comparison voltage generator and provides a load enable signal whenever the compared signals coincide with one another. A digital memory is provided to be  responsive to the load enable signal to store the instan-taneously occurring count output.  The load enable signal can be inhibited except upon actuation of a touch switch associated with the comparison voltage generator, and can be controlled to occur only with predetermined counts of the counter.  The apparatus is of particular use in a frequency synthesizer radio receiver.
