  • Patent number: 4343418
    Abstract: Device for dispensing liquids wherein a discardable tip of a dispenser is instantaneously automatically ejected upon application of slightly excessive thumb pressure to a member of the dispenser which, when normal thumb pressures are applied thereto, causes the liquid to be controllably dispensed through said tip onto a target such as a dentition surface.

  • Patent number: 4321472
    Abstract: Panoramic dental X-ray machine wherein the camera assembly is physically detached from the tubehead assembly to prevent their rotation as an integral unit around the patient's head. Essentially, the detached camera assembly, modified in accordance with one aspect of the invention, is positioned above the head of the patient and its semi-cylindrical film carrier carries X-ray film therewith. The film carrier is cupped about the patient's face with an inner drum or mask configured similarly to the film carrier interposed between the film carrier and patient's face. The film carrier and film are then rotated at slow non-linear speeds by the film drive mechanism of the camera assembly in accordance with the type radiograph desired, i.e., continuous or discontinuous. The many advantages of the disclosed panoramic X-ray machine are cited.

  • Patent number: 4228760
    Abstract: Boat's engine speed and direction of rotation of the engine's propeller shaft are remotely controlled at the helm. Movement of hand control knobs through a semicircular area controls the full range of speed of the engine as well as its forward-neutral-reverse actuator. The knobs rotate a pulley structure which steps up rotation to flexible shafts. The stepped-up rotation of the flexible shafts is converted to linear motion by ball screw cylinders having output members connected to the engine's speed and propeller shaft actuators.

  • Patent number: 4194121
    Abstract: Two different areas of a focal trough of a dental arch structure are simultaneously displayed on a radiograph when tubehead-camera assembly of an X-ray machine panoramically scans the dental arch structure. The different areas of the focal trough are obtained when a pair of parallel disposed film holding devices within the camera are caused to travel in proximate relationship to each other at different speeds. The X-rays activate and pass through one film before activating the other immediately therebehind.

  • Patent number: 4185473
    Abstract: Remote control flexible shaft having a balanced torsion deflection in either direction of rotation when subjected to torsional loads. Balanced torsional deflection provides the same "feel" of the control element, whether a wheel, valve, knob, or the like, and the same "lag" period before response of the controlled element, regardless of direction of rotation of the control element. The shaft employs interconnected equal lengths of conventional flexible shafting of identical construction except for the opposite lay of the wires comprising each respective layer of each length. Specific torsional deflection characteristics may be obtained by varying lengths and/or construction of the two flexible shaft lengths, or more than two lengths of shafting may be employed.

  • Patent number: 4185474
    Abstract: A device for coupling power from a high speed rotating flexible shaft to a spindle of a portable worktool. The flexible shaft is contained within a casing. The casing is crimped within a ferrule which is threaded into a handpiece which an operator holds in one hand to guide the worktool. Upon movement of the worktool on the workpiece by the operator, the casing becomes twisted to encourage loosening of the threaded connection between the ferrule and handpiece, thus endangering the operator. In lieu of the prior art threaded connection between the ferrule and handpiece, a retaining member engages both to prevent their dangerous separation by virtue of the handpiece and retaining member being free to slowly rotate about the ferrule in a direction to automatically relieve twisting stresses introduced into the casing caused by movement of the worktool by said handpiece on or about a workpiece.

  • Patent number: 4031172
    Abstract: An improved process for producing colloidal nitrocellulose having a high vimetric loading density by a shock gel type process is provided. Process improvements result in part from the use of 13.35%N as the source of nitrocellulose and from the use of diethylene glycol monomethyl ether as the shock gel solvent. Gravimetric loading densities of at least 0.95 gm./ml. are achieved through this process.
