Title: Torque measuring device
Inventor: SCHUBERT LES
IPC: G01L3/14
Filed: 1985-06-07
Granted: 1988-03-08
Abstract: ABSTRACT OF THE DISCLOSURE A device for measuring the torque of a rotating shaft when the torque exceeds a predetermined level includes adjacent drive and follower hubs on the shaft, the drive hub being connected to the shaft and the follower hub being rotatable on the shaft; a plurality of helical springs extending perpendicular to the longitudinal axis of the hubs interconnecting the hubs; an indicator ring on the side of the drive hub opposite to the follower hub; and a plurality of pins connected at one end to the indicator ring and extending through bushings in the drive hub into engagement with inclined cams in the follower hub.          When the torque on the shaft exceeds the predetermined level, the force of the springs is overcome, and the pins ride up the cams to move the indicator ring away from the drive hub a distance directly proportional to the amount by which the torque exceeds such predetermined level.

Abstract: ABSTRACT                Optical Switching Means A node of an optical transmission network, for example a local area network, has a combined by-pass switch and optical modulator.  The by-pass switch and modulator comprises an optical switching matrix with two non-intersecting waveguides connected by a further waveguide.  The junctions between the non-intersecting waveguides and the further waveguide perform both modulation of an optical carrier signal and re-routeing of the transmission path along the network.

Abstract: PRECIS DE LA DIVULGATION:         Un répéteur pour distribution d'horloge tripli-quée dans lequel chaque horloge délivre un signal d'horloge et de synchronisation ayant un signal d'horloge et un signal de synchronisation.  Le signal de synchronisation est constitué par une impulsion négative et une impulsion positive chacune ayant une durée égale à la période du signal d'horloge, et une horloge est reliée par au moins un répéteur à un récepteur.  Un répéteur comprend un inverseur, un circuit d'inversion, un circuit de test, un circuit de restitution et de décalage et un circuit de régénération.  Le circuit de test effectue un test de la durée des impulsions pour détecter le signal de synchroni-sation et délivrer une impulsion suite à la détection. Le circuit de restitution délivre une impulsion de durée égale à une impulsion du signal de synchronisation, déca-lée de deux périodes du signal d'horloge.  Le circuit d'inversion inverse le front entre les deux impulsions du signal de synchronisation et le circuit de génération d'horloge délivre un signal d'horloge et de synchronisa-tion en sortie du répéteur.

Abstract: ABSTRACT     During the use of a roller paint tray, positioning of the paint tray is restricted to the horizontal le-vel.  In this invention the roller paint tray is en-closed, thereby allowing the tray to contain paint while it is in a vertical or inclined position.  This refinement allows the roller paint tray to hang from an erected ladder, stand inclined on a floor, hang vertically, or lay in the traditional position.                 SPECIFICATION    This invention relates to a manually operable paint tray used for applying paint on a paint roller.   It is common during the use of roller paint trays that the trays are positioned horizontally.  This single position restriction is a direct consequence of the open tray design, and limits the use of roller paint trays to horizontal platforms such as a step ladder or a floor.  Threfore, the horizontal placement criteria practically makes it impossible for a per-son to paint the exterior of house from an inclined ladder, while having convenient acces to a roller paint tray.    This invention overcomes the above disadvanteges by enclosing the bottom section of the tray. This enclosement allows the tray to be used without spilling any paint while it is hanging from a ladder step.

Abstract: Case 1469F     ABSTRACT OF THE DISCLOSURE          Disclosed is a data storage device having a chalcogen data storage medium encapsulated along at least one surface, and preferably both surfaces, by a dielectric barrier layer.  The dielectric may be compositionally graded in oxygen content with respect to the chalcogen data storage medium, a substantially stoichiometric oxide in proximity to the chalcogen data storage medium, and a substantially non-stoichiometric suboxide remote from the chalcogenide data storage medium.  The state changeable chalcogenide layer may have a morphology enhancing component in contact therewith.  The data storage medium may be substantially oxygen free and comprise a chalcogenide, a cross linking magnet, and a switching modulator. The switching modulator is a transition metal, especially from the right hand column of Group VIII, e.g. nickel, palladium, and platinum.  The concentration of the switching modulator in the data storage medium is high enough to suppress grain growth during written storage, to provide random crystallite orientation and to increase the erase velocity, but low enough to permit discrimination between detectable written and erased states of the data storage medium.         Also disclosed is a method and apparatus for depositing material on a substrate by periodically measuring an optical property of a region thereof, thereby obtaining a substantially continuous profile of the property for that region.  The measured value of the property is compared with a predetermined value, and when the two values are substantially equal, deposition is terminated, thereby resulting in correct and reproductible layer thicknesses.   1155d

Abstract: UNI-DIRECTIONAL FIN-AND-TUBE HEAT EXCHANGER      Abstract A fin and-tube heat exchanger designed for one-way airflow, in which louvers, formed from the fin stock, progressively increase in length from the fin leading edge to its trailing edge.  Their end walls channel air into stagnant air spaces behind the tubes.          The tube collars may be offset somewhat toward the fin trailing edge, further reducing the stagnant air zones.  In -those bent heat exchangers in which air flows in from outside the curve, offsetting the collars also lessens the angular convergence of fin trailing edges inside the curve and presents less resistance to airflow.

Abstract: The invention concerns a field sprayer with a spraying bar 1 and a number of hydraulic spraying nozzles 7. The field sprayer can be of the lift-suspended or trailer type. In combination with the spray nozzles 7, the spray bar 1 is provided with a number of downward directed air nozzles 4, which are supplied with blown air from a central blower 3. This is driven by a hydraulic motor 3a, connected to the hydraulic offtake of the tractor. Flexible hoses 5 connect the individual air nozzles to the blower. During the operation of the sprayer in the field, a powerful almost pointlike air flow is directed downward against the crops, while at the same time the spray liquid is brought out in liquefied form through the spray nozzles. The liquid drops mix with the air flow and are carried along with it down onto the crops. The dynamic pressure of the air flow causes the crops to "open up" and a turbulence is produced in the stem and leaf mass of the crops themselves, which contributes to an effective distribution of the spray liquid. The pointlike air flow counteracts wind drift in blustery weather. In a preferred embodiment, the blowing equipment, blower, hoses, nozzles, etc., can be mounted on existing field sprayers. <IMAGE>

Abstract: A method and apparatus for increasing the response sensitivity and the interference resistance in an alarm system such as a fire alarm system which cyclically samples a plurality of alarm units in the system for obtaining a series of measured values from each alarm unit, the measured values being utilized to form a quiescent value which is stored in a quiescent value memory. With each sampling cycle a current comparison value is formed from the alarm measured value, the stored quiescent value, and a comparison value from a previous sampling cycle stored in a comparison value memory. The current comparison value is then written in the comparison value memory as the new comparison value. The current comparison value is compared with a rated limiting value, and if the comparison value is greater than or equal to the rated limiting value, a display unit is activated indicating an alarm. If the comparison value is less than the rated limiting value, a new quiescent value is formed from the measured value and the stored quiescent value and written into the quiescent value memory.
