Title: Laser system
Inventor: HOLLINS RICHARD C
IPC: H01S3/225
Filed: 1987-12-21
Granted: 1991-03-12
Abstract: ABSTRACT          A laser system comprises a XeF excimer laser and a dye laser with a common laser cavity mirror.   The excimer laser generates an ultraviolet pulse which pumps the dye laser.  The dye laser responds by producing a blue/green laser pulse which is weakly coupled via the laser mirror to the XeF excimer laser.  The blue/green pulse then effects injection control over build up of blue/green radiation in the XeF excimer laser.  The XeF laser accordingly produces a blue/green output having inter alia a wavelength determined by the dye laser properties.  Unlike prior art devices,  the invention does not require two lasers independently pumped in synchronism.

Title: Shaving cartridge retaining casings and storage tray therefor
Inventor: APPRILLE DOMENIC V JR
IPC: A45D27/24
Filed: 1988-03-07
Granted: 1992-02-04
Abstract: ABSTRACT OF THE DISCLOSURE The present disclosure is directed to a plurality of individual protective safety razor head unit open top casings and a tray for storing the plurality of casings in side-by-side relationships.  Each of the casings are adapted to retain a single safety razor cartridge unit therein, each of which have at least one blade and a head cartridge member to which the blade is permanently secured and which also provides a guard surface.  The head unit is detachably engageable with a safety razor handle.  Each casing defines a single chamber in which a single shaving head unit is retained. The structure in each casing retains the head unit therein against accidental removal in such a manner that the cutting edge of the blade is protected against damage and wherein the head unit is engageable by the handle while the head unit is still within the casing.  Each head unit when engaged with the handle is withdrawable from its casing by means of rocking the handle. The tray comprises slide means securing structure to secure each individual casing in the tray in a side-by-side relationship, and the tray and slide means are so configured as to permit each of the casings to be slid endwise out of the tray by the handle engaged with the razor head such that with the handle engaged with the head an operator may remove the blade unit from the casing or may alternatively slidably remove the blade unit and casing from the tray.

Granted: 1993-05-18
Abstract: ABSTRACT           A connection for connecting lengths of pipe in end-to-end relation includes a cylindrical coupling element, threaded at each end to receive a threaded coupling member.  Internally, the coupling element has a frustoconical surface engageable by a corresponding surface on an annular coupling ring. Internally the coupling ring has a plurality of sharp-edged annular ribs for gripping the external surface of a pipe   The clamping ring has a central helical slot extending therethrough,  for about four turns, and a flat end surface facing a flat locating surface on the coupling member.  The slot winds in the opposite direction to that of the threads between the coupling element and the coupling member.  As the coupling member is tightened into the coupling element it will engage the coupling ring to force it into sealing engagement, via the mating conical surfaces, with the pipe, and also to twist the body of the coupling ring, due to the helical slot, to improve sealing and to improve the resistance of the connection to separation.
