Abstract: ABSTRACT         This invention is a fluid flow meter with pulse output proportional to the fluid flow rate. The pulse is transduced by means of a pick-off sensor from the by-passing of a ball which travels in a toroidal passageway at speed close to that of the velocity of the fluid. The fluid flowing into the device follows a loop-shaped circular passageway while the ball travels in a closed circular passageway. Fluid flow propels the ball to revolve continu-ally at a rate directly proportional to the flow rate of the fluid.

Abstract: ABSTRACT OF THE DISCLOSURE    This headset includes a capsule intended for mount-ing over either ear of the wearer,  The surface of the headset capsule adjacent to the ear is contoured to fit snugly behind either ear.  A microphone is mounted on a boom projecting from the front end of the capsule.  The boom is tiltable and rotatable so that the position of the microphone may be adjusted relative to the mouth.  The rotatability of the boom on the capsule permits adaptation of the headset for wear over either the right or left ear. The boom is curved to keep it out of contact with the face of the wearer.  An ear tube extends from the lower end of the capsule at the central plane thereof and is flexible so that it may engage either the right or left ear, depend-ing on the location of the headset.   The bottom of the capsule is provided with an ear clip for the purpose of maintaining the position of the capsule and microphone during motion of the head.  This ear clip assembly captures the ear lobe and is adjustable to encompass a wide range of ear sizes. The ear clip assembly is removable and reversible so that it may grip the lobe of either the right or left ear of the wearer.

Abstract: ABSTRACT OF THE DISCLOSURE         An improved caged disc valve in a metering container is disclosed.  A cage contains a resilient floatable disc member adjacent an outlet passage at the bottom of the container.  The cage is generally circular with a flat top wall and side walls, there being one or more openings in the side wall.  The interior surfaces of the side and top walls have a number of inwardly projecting ribs which function to prevent the disc from adhering to either the top or the side walls as liquid is dispensed from the container.  This assures that the disc will reliably operate to close the outlet passage and prevent air from going beyond this passage when the level of the liquid reaches the outlet passage.

Abstract: TRIGGER OPERATED TOOL HANDLE SWITCH          ABSTRACT OF THE DISCLOSURE         An electrical switch having spaced stationary con-tacts and a contact carrier carrying a bridging contact in linear reciprocation relative to the stationary contacts, with the bridging contact biased toward the stationary contacts.  The bridging contact has spaced opposite contacting ends forming a leading contact end and a trailing contact end for sliding move-ment between a bridging position where the contacting ends con-tact their respective stationary contacts, and a non bridging position where the leading contact end is out of engagement with its stationary contact.  The bridging contact is rotatably hinged to the contact carrier and a projection is disposed be-tween the stationary contacts for engagement with the leading contact end for pivoting and lifting the leading contact end from its stationary contact in coaction with the hinged connec-tion with a quick break action during movement of the contact carrier to the non-bridging position.         Each conductor wire connected to the switch is releas-ably secured therein by a spring-like retainer blade biased diagonally against the wire.  Each retainer blade has a release arm for deactivating the retainer blade thus permitting easy withdrawal of the conductor wire.  The release arm has a later-ally extending handle lug on its exteriorly exposed free end to provide a handle and also to provide for engagement with the switch housing to limit inward movement of the release arm.          The inner end of the release arm is beveled to provide a plane-to-plane contact with the retainer blade for a positive contact therewith.

Abstract: ABSTRACT OF THE DISCLOSURE          A process for economically converting carbo-metallic oils to lighter products includes providing a converter feed containing 650°F+ material, the 650°F+ material being characterized by a carbon residue on pyrolysis of at least about 1 and by containing at least about 4 parts per million of Nickel Equivalents of heavy metal(s).        The converter feed is brought together with a cracking catalyst to form a stream comprising a suspension of the catalyst in the feed, and the resultant stream is caused to flow through a progressive flow type reactor having an elongated reaction chamber which is at least in part vertical or inclined for a pre-determined vapor riser residence time in the range of about 0.5 to about 10 seconds at a temperature of about 900 to about 1400°F and under a pressure of about 10 to about 50 pounds per square inch absolute sufficient for causing a conversion per pass in the range of about 50% to about 90% while producing coke in amounts in the range of about 6 to about 14% by weight based on fresh feed, and laying down coke on the catalyst in amounts in the range of about 0.3 to about 3% by weight.        The catalyst is ballistically separated from the stream of hydrocarbons formed by vaporized feed and resultant cracking products in the reaction chamber by projecting catalyst particles in a direction established by the elongated reaction chamber or an extension thereof, the products being caused to make an abrupt change of direction relative to the direction in which the catalyst particles are projected.        Adsorbed hydrocarbons are stripped from the separated catalyst, which is then  regenerated with oxygen-containing combustion-supporting gas under conditions of time, temperature and atmosphere sufficient to reduce the carbon on the catalyst to about 0.25% by weight or less, while forming gaseous combustion product gases comprising CO and/or CO2.     The regenerated catalyst is recycled to the reactor for contact with fresh feed.

Abstract: ABSTRACT A method and composition for non-destructive testing of magnetizable workpieces such as steel billets. A dry dispersion of ferromagnetic particles in combination with a fluorescent pigment and a water-soluble carrier are deposited on the workpiece which is simultaneously or thereafter magnetized.  The magnetizable particles are attracted to surface imperfections by the action of the magnetic field and become clustered therein to form indications.  The indications are fixed more firmly to the piece by applying an aqueous spray, consisting either of a water mist or steam which activates the water-soluble carrier so that upon drying, the indications remain firmly attached to the workpiece.  Subsequent examination of the workpiece under ultraviolet irradiation enables the inspector to determine the extent and the locations of the flaws.

Abstract: TITLE OF THE INVENTION "PERIODIC PULSE FORMING CIRCUIT"     ABSTRACT OF THE DISCLOSURE       A periodic pulse forming circuit, e.g. for distinguishing valid horizontal sync signals from noise signals in the separated horizontal sync signal train from a reproduced video signal in a VTR uses a saw-tooth generator 14 and a sample and hold circuit 15 to produce a signal representing the interval between successive pulses.  Each sample from the sample and hold 15 is compared by a window comparator 17 with a signal representing the  average interval between pulses to establish whether the interval between successive pulses is within a predetermined range.  If it is, the second pulse is passed by a gate 18 but if it is not, the pulse is blocked.  The noise pulse signals are thus removed.          The circuit enables the reliable elimination of noise pulses even where the tape replay rate is varied for fast and slow motion reproduction.
