Abstract: A timepiece to be worn on the person which provides a silent mechanism alarm in the form of a tactile stimulus to the wearer when the chosen alarm time is reached. The tactile stimulus is provided by a motor attached to or integral with the timepiece and which may be driven by the same battery. The motor may actuate an element which creates the tactile stimulus in the form of vibrations, oscillations, a thumping sensation or a tightening of the wristband, among others.

Abstract: Internal pipe inspection apparatus and an in-line pipe head are disclosed. The inspection apparatus is insertable into either a four inch or six inch pipeline through a standard service size opening. The apparatus includes a compact pipe head having a viewing assembly for imaging the interior of the pipe. The head is sized to pass through the standard lateral service opening, the opening being substantially less in size than the diameter of the pipe. A flexible steel snake is connected to the head for manually moving and rotating the head within the pipe once the head is positioned therein. The apparatus is intrinsically safe for inspection of a live natural gas main. Various centralizing member embodiments are disclosed for positioning the pipe head viewing assembly substantially concentric with the axis of the pipe.

Abstract: A device intended primarily for use in a shower stall that is adapted to dispense a predetermined total amount of a selected additive into a water stream, with the rate of mixing of the additive and water being controlled as a function of the water pressure. A positive displacement pump is used to dispense the additive from a storage chamber, and the additive is dispensed via a controllable applicator device.

Abstract: An opto-mechanical coupler is described for providing a quick-release mechanical and optical connection between a camera and the eyepiece of an endoscope or other optical instrument. The coupler comprises a hollow body member that is adapted to be screwed into the threaded aperture of a camera and is characterized by a center bore for transmitting images from the endoscope to the camera, and eyepiece clamping means attached to the hollow body member.In one embodiment, the eyepiece clamping means comprises a single clamping member defining a channel for receiving the eyepiece, and means rotatably connecting the clamping means to the hollow body so that rotation of the clamping member in one direction will cause the eyepiece to be clamped to the hollow body and rotation in a second opposite direction will unclamp the eyepiece from the hollow body.

Abstract: An improved surgical fastener having at least one head portion and a filament portion arranged in a T configuration, wherein at least one end of the said at least one head portion is sharply pointed, so that when that head portion is implanted in body tissue, the head portion will attach itself securely to the tissue and will remain there despite the application of a substantial pulling force on the filament portion.

Abstract: A surgical cannula having a first seal member having a substantially conical shape and an opening at the tip thereof, and a second seal member having a substantially conical shape and a slit at the tip thereof, whereby (a) when an instrument is inserted into the cannula, the instrument can pass through the first and second seal members into proximity with a surgical site located beneath the cannula, and fluid entering the cannula from the site will force the first seal member to close around the instrument and form a tight seal therewith so as to prohibit fluid from passing out of the cannula and (b) when no instrument is inserted into the cannula, fluid entering the cannula from the site will force the conical second seal member to close tightly on its slit and thereby form a tight seal so as to prohibit fluid from passing out of the cannula.

Abstract: A pistol design is provided which makes it possible to make a small sized pistol for firing relatively large size cartridges, e.g. a .45 pistol. The pistol is manually cycled for reloading and is characterized by a barrel which must be moved forward to remove a spent case and backward to chamber a new cartridge, and novel means for (a) firing the weapon, (b) preventing accidental discharge of the weapon, and (c) preventing forward movement of the barrel when the trigger is pulled.
