Title: Method and apparatus for treating an ophthalmic lens mold
Inventor: ADAMS JONATHAN PATRICK
IPC: B29C39/22
Filed: 1993-12-20
Abstract: An apparatus and method for directing accelerated electrons to at least part of one surface of one ophthalmic mold piece prior to filling with monomer and lens polymerization. In particular it has been found that generation of the ionized oxygen by means of a corona treatment electrode sufficiently increases the adherence of the polymer to the mold piece so treated. In the preferred embodiment, the flange around the convex, male piece of the lens mold is corona treated so that when the mold pieces are separated after lens polymerization, the flashing of excess polymerized material surrounding the lens cavity adheres to that male, convex piece flange while the lens is removed with the female, concave piece. <IMAGE>

Title: Door closer
Inventor: LASSON REX H
IPC: E05F15/20
Filed: 2000-04-20
Granted: 2002-10-23
Abstract: A door closer has a low melting point e.g. plastics, plug (48) in an aperture in the top of the closer body. In the event of a fire, as the door heats up, the closer body also heats up. When the temperature of the closer reaches approximately 250{ F (120{ C), the hydraulic fluid within the closer will begin to emerge from the plastics plug area and spills over and collects in the top of the closer body casting which forms an open-surfaced, fluid-retaining reservoir. The contained fluid smokes and evaporates from the heat. No fluid escapes down to the door and the floor. This reduces the chance of causing a fire on the non-fire side of the door and frame.

Title: Self sealing water trap
Inventor: JASSELL SURINDERJIT KUMAR
IPC: B01D45/02
Filed: 2002-12-06
Granted: 2005-04-20
Abstract: A water trap suitable for use in a mechanical ventilation circuit comprising a cap with an inlet and an outlet, a fluid collection vessel engageable with the cap, and a rotatable closure with at least one aperture interposed between the cap and the vessel. The vessel is operably linked to the closure such that engagement or disengagement of the vessel from the cap causes the closure to be rotated. The cap is formed with an internal partition extending into abutment with the closure to define a chamber via which the inlet and outlet are in fluid communication and the closure forming a base of the chamber. When the vessel is engaged with the cap, the closure has a first orientation in which the at least one aperture is located within the periphery of the skirt in the base of the chamber and the vessel is in communication with the chamber via the at least one aperture. When the vessel is removed from the cap the closure is rotated to a second orientation in which the at least one aperture is located externally of the periphery of the skirt and the base of the chamber.

Patent GB-2451664-B (GB)
Title: Injection device
Inventor: JENNINGS DOUGLAS IVAN
IPC: A61M5/20
Filed: 2007-08-08
Granted: 2012-06-20
Abstract: An injection device has a locking mechanism that in an engaged position prevents removal of a protective cap 111 and in a disengaged position prevents forward motion of a syringe 114 and its carrier 127 but permits removal of the cap from the injector housing (112, figure 1a). This assists in preventing damage to the syringe prior to actuation of the injection device. Two buttons 171 located on the front end of the injection device are depressed to move locking arms 173 out of engagement with the cap. The same motion brings abutment surfaces 179a on the arms into engagement with the syringe carrier to prevent it from moving forwards. The arms may extend through and so secure a sliding sleeve (119, figure 2a) and thereby prevent triggering of the injection mechanism whilst the cap is being removed.

Title: Improvements in electric cables and installations
Inventor: BALL EDMUND HUGH
IPC: H01B9/02
Filed: 1982-07-20
Granted: 1985-07-31
Abstract: A single-core electrical power cable for use at 400 kV for example has a relatively high-resistance inner shield located between and insulated from the central core of the cable and its low resistance metallic outer sheath. The inner shield is kept continuous throughout the cable run of installations where, for avoidance of currents circulating in the cable sheath, the sheath continuity is broken at spaced-apart locations. By virtue of such continuity, the inner shield provides a continuous path for surges developed in the cable as the result of lightning strikes or switching operations thereby preventing the development of corresponding high transient overvoltages at the outer cable sheath and particularly at the discontinuities therein. It is thus possible to dispense with the surge voltage limiters previously required to be coupled to the outer cable sheath at intermediate positions of cross-bonded systems.
