Title: Quick connection for fitting a rigid tube in a connector
Inventor: DETABLE PASCAL
IPC: F16L37/084
Filed: 1994-08-23
Granted: 2005-10-18
Abstract: This invention relates to a connector of a quick connection allowing tight connection of a rigid tube provided, at some distance from its free end intended to be fitted in the inlet of the connector, with a bead projecting radially with respect to the outer surface of the tube and presenting a substantially radial side opposite said end. The connector presents a first inner housing comprising an O-ring capable of coming into contact with the outer surface of the tube between its free end and its bead and a second inner housing to receive a locking ring elastically deformable in the radial direction.      The locking ring is formed by a thin metal band presenting a generally oblong profile, the central region of said ring being constituted by substantially cylindrical portions whose diameter in the free state is at the most equal to the diameter of the tube. The zone located at one end of the large diameter of the oblong profile is constituted by a bridge in the form of an upturned U whose base essentially forms a part radially projecting outside the body of the connector.

Granted: 1998-07-14
Abstract: An interdental toothbrush has a hinged locking retainer on the end of an elongated handle for capturing the stem of a twisted wire brush. The locking retainer has a hole which is adapted to receive the stem of a twisted wire brush. A land is formed in the handle adjacent the groove so that the wire brush stem is captured between that land area and a land area on the retainer. A latch on the locking retainer has a top end with a double cam surface thereon. One of the camsurfaces guides the latch into a locking position as the retainer is closed. Theother of the cam surfaces releases the locking retainer when pushed.

Title: Apparatus and method for dispensing electrically conductive coating material including a pneumatic/mechanical control
Inventor: KONIECZYNSKI RONALD D
IPC: B05D1/00
Filed: 1994-05-16
Granted: 2004-09-28
Abstract: An apparatus for transferring electrically conductive coating material comprises a filling station having a first coupling element connected to a source of the coating material and a shuttle carrying a second coupling element which is movable with respect to the filling station between a paint transfer position in which the coupling elements engage and a neutral position physically spaced from the filling station.

Abstract: The input voltage VR is detected by means of a voltage detecting device and the phase .PHI. of the input voltage is detected by means of a phase synchronizing circuit.  The detected phase is input to an AC sine wave reference oscillating circuit in order to obtain an AC sine wave reference signal having the same phase as input voltage.  The output of an amplitude instruction generating circuit is multiplied by an AC sine wave reference signal by means of a multiplier in order to obtain a converter current instruction IA*.  On the other hand, the input current IR detected by means of a current detecting device is differentiated by means of an approximation differentiator and only the resonance frequency component is detected by means of a band-pass filter.  The detected resonance frequency component is multiplied by the gain K by means of a proportion device and the output is subtracted from the converter current instruction IA*  by means of a subtracter.  The current control amplifier and PWM modulating circuit control a converter so as to make the output from the subtracter agree with the converter current IA*  detected by a current detecting device.

The plug can also be secured tightly  in position when  inserted  into  the automobile cigarette  lighter socket and which is easy to manufacture and assemble. The plug comprises a case body having its surface formed with two opposed openings and two opposed elastic pieces positioned symmetrically with respect to the openings; a conducting strip, which is elastic and substantially ring-shaped, with two sides exposing to the outside of the case body through the openings,  respectively; and conducting means,  connected between the conducting strip and the electrical  outlet of the automobile cigarette  lighter socket.  With  the  foregoing arrangement,  when the plug is inserted  into the automobile cigarette lighter socket,  the conductive strip and the elastic pieces on the case body in combination exert a pressure on the inner wall of the automobile cigarette lighter socket so as to secure the plug therein.   The plug therefore can be adaptively inserted into cigarette lighter sockets of various calibers.

Granted: 1999-08-03
Abstract: An apparatus for controlling the spacing between information tracks while recording information on an optical disc that does not have pre-manufactured information tracks. The invention employs a reference scale to precisely determine the position of information tracks to be recorded on an optical disc, wherein spacing of optical tick marks on the reference scale directly correlates to track pitch between information tracks recorded on the optical disc. The invention utilizes a first optical system for reading-from and writing-to an optical disc. A second optical system is used for detecting optical tick marks on the reference scale. The first optical system and the second optical system share common optical components, and are used in cooperation with control means to direct an optical pickup to a desired location of the optical disc for recording an information track thereon.

Abstract: The ergonomically improved hand tools include an improved handle which has a handle grip portion set at an angle to the tool head. The angle at which the handle grip is set to the remainder of the tool handle is a compound angle arranged such that the handle grip portion extends laterally of the remainder of the handle and angles downwards vertically into the hand when being gripped. This compound angle has the benefits of the Bennett handle as well as brings the tool head into alignment with the forearm of the individual using the handle which the Bennett handle fails to do. The improved hand tool handle is adaptable for use with most currently used hand tools and may be employed in any application where its use would be appropriate. The ergonomically improved hand tools provide an ergonomically redesigned hammer having the improved handle which reduces the risk of repetitive strain injuries. An extended fulcrum point is located at the top of the hammer head for improving the nail extracting characteristics of the hammer claw.      The hammer claw has claw members that are angled relative to one another enabling the claw to access nails located in corners, along baseboards and at other locations where two surfaces meet at an angle. The hammer handle as well as the improvements discussed above includes the further improvement of being made from laminated materials which increases the strength of the hammer handle and helps dampen vibration. An improved paint brush and scissors are also provided. Both the paint brush and the scissors include the improved handle arrangement.
