Abstract: This invention relates to a film winding and rewinding machine characterized by a single unidirectional motor being used in cooperation with a pair of electrically-actuated clutch/brake units and a suitable power train to actuate the take-up reel in either direction. It also encompasses an automatic mechanism responsive to the tail end of the film leaving the hub of the supply reel to shut off power to the motor and stop the take-up reel in both the FORWARD and REVERSE modes. It further envisions using the drag of the friction brake in whichever of the clutch/brake units is actuated into its clutch mode to apply a variable tension to the film coming off of the reel functioning in the capacity of the supply reel.

Abstract: This invention relates to a multiple ply assembly form that is especially adapted for use with a computer printer and which enables the user to simultaneously generate an original and at least two copies of an invoice and the customer's itinerary with the latter appearing on the upturned face of the bottom ply which folds to produce a ticket jacket having both a ticket pocket on the inside and a boarding pass-receiving slit on the outside.

Abstract: This invention relates to a cable anchoring device in the form of a stamped metal blade-like part having a generally straight lower section and a slightly curved upper section terminating at its upper end in a point. The curved section of the blade contains an elongate tool-receiving aperture, the lower end of which is shaped to accept a slotted driving tool while its upper end engages the shank of the tool and maintains the latter in substantial axial alignment with the straight section. An integrally-formed dimple with a cable-receiving hole in it is located on the outside of the blade just underneath the lower edge of its tool-receiving aperture through which the anchor cable passes onto the inside thereof. Immediately underneath the dimple, but on the inside of the blade is an integrally-formed downturned ear beneath which the cable is passed preparatory to being crimped in place.

Abstract: This invention relates to an improvement upon the film winding and rewinding apparatus forming the subject matter of my copending application Ser. No. 666,187 filed Oct. 29, 1984, by a replacement of its former manually-shifted electrochemical reversing system for changing from a so-called "A-wind" to a "B-wind" with an electromagnetic one employing a pair of electromagnetic clutches on parallel counterrotating output shafts operatively linked together with a belt and pulley power transfer mechanism which cooperates with the clutches to impose a drag upon the supply reel regardless of which direction it is being turned by the power supplied to the take-up reel. The invention also encompasses an electromechanical circuit in which an idler spool responsive to the tension in the film passing between the supply and take-up reels actuates a potentiometer which, in turn, lessens the drag on the supply reel as the tension increases.

Abstract: This invention relates to a rifle cartridge magazine for carrying and automatically feeding a plurality of rifle cartridges one at a time sequentially into the breech of a rifle characterized by a housing open at the top containing an arcuately-curved cartridge compartment therein sized and shaped to define a track effective to engage the front and rear ends of each cartridge and guide same into the breech, a pair of ribs depending from one face of the housing and extending into the cartridge compartment in spaced parallel relation to one another defining rails paralleling the front and rear ends of the track located in between the latter, a follower provided with spaced parallel slots extending transversely thereof on one side for riding the rails, the aforementioned slots and rails cooperating with one another to maintain the follower in substantially perpendicular relation to the track ends, and at least one constant force coiled clock spring having one end pivotally secured adjacent the open upper end of

Abstract: This invention relates to an improved apparatus for directly detecting and monitoring uterine bio-electrical activity "in vivo" characterized by an electrode carrier in the form of a cup shaped to conform to the patient's cervix and hold the electrodes contained therein in such intimate contact with the cervical tissue that an impedance match therebetween is established and maintained at a level of less than 10,000 ohms without the aid of suction. The invention is also characterized by non-invasive, broad-headed, low profile solderless electrodes. The invention is further characterized by the use of a multiple-electrode pattern containing at least three electrodes arranged such that separate and distinct current paths exist between each electrode and the others whereby discrete signals can be detected, monitored and charged.

Abstract: This invention relates to an improved hub for diamond-edged concrete saws and, more particularly, to a hub or mandrel of the so-called "flush" type which mounts the saw blade such that the latter can make a cut while lying flush against a planar surface like, for example, a floor or wall. The hub is characterized by an rearwardly-opening donut-shaped annular groove bordering its hollow central core area which receives cooling water delivered thereto from a stationary source in the form of an inlet pipe and then disperses same centrifugally onto the remote surface of the blade mounted thereon by means of passages leading out of the groove and passing through the hub onto the aforementioned remote surface of the blade closely adjacent the central opening therein.

Abstract: This invention relates to an improved pitot tube type flow measuring instrument for use in pipes and other conduits characterized by a generally diamond-shaped sensor portion constituting a bluff body for splitting the flow that includes at least a large-radiused leading edge in which three or more impact ports are located, a pair of planar portions diverging rearwardly from the leading edge to a transversely-spaced pair of much shorter-radiused side edges that cooperate therewith and the downstream-facing portion of the bluff body to define flow separation zones capable of stabilizing the flow coefficient over a broad range of flow conditions provided that the distance separating them is at least five times either of their radii.

Abstract: A pair of rotating flywheels which engage a ram for moving a tool which impacts a part, such as a nail to be driven, are rotated in opposite directions from a single motor or other rotating means, through a pair of substantially identical gears, one of which drives one flywheel and the other of which drives the other flywheel. The drive connection between the respective gears and each of the flywheels may include a belt and pulley arrangement, so that each flywheel may be driven directly by the respective belt but the flywheels are pivoted toward and away from the ram so that when the flywheel moves toward the corresponding side of the ram, the connection between the belt and the corresponding pulley will tend to slacken. A special flywheel pulley has an inner V-shaped groove and parallel side walls for guiding the belt into the groove when full tension occurs.

Abstract: This invention relates to an improved apparatus for one person to use in effecting an escape from a tall building or the like under emergency conditions, such apparatus including a novel load-lowering device in the form of a small cylindrical drum having generally teardrop-shaped apertured endplates on both ends thereof and an eye projecting therebeneath for attachment of a load-carrying sling. The elongate portions of the teardrop-shaped endplates are vertically aligned and project beyond the surface of the drum, such projections containing the apertures. A rope is threaded onto the load-lowering device by first being passed up and in through the aperture in the lower endplate, then wrapped three or four turns around the drum before finally being passed up and out through the aperture in the upper one or vice versa.
