Title: Sub-conscious eye exerciser
Inventor: SHYU JIA-MING
IPC: H05B39/08
Filed: 1993-04-14
Abstract: The luminosity Lb of a light source B eg bulb, VDU is modulated by varying the power supplied Va to the light source B cyclically in such a way that the muscles of the eye are exercised without the change in brightness being perceptible. Input means (figure 8) permit the amplitude and period of the variation and the average value of power supplied to the light source to be input by the user. Feedback means can be incorporated to automatically adjust the amplitude and period of the variation of power supplied to the light source according to the detected luminosity and the basic luminosity can be gradually increased to produce a natural waking effect (figure 10). <IMAGE>

Patent GB-2274344-A (GB)
Title: A fluid discharge valve
Inventor: FROST DOUGLAS ROBERT DAVID
IPC: E03D1/34
Filed: 1992-09-04
Abstract: A fluid discharge device, primarily for w.c. cisterns, has a housing (4, 9) with an outlet (5) through the base of the cistern (1). A main valve assembly (20) with a seal (21) normally blocks this outlet (5). A substantially closed variable volume chamber (26) is formed in the housing (4, 9), the main valve assembly (20) providing its base. A pilot valve (12, 30, 36), controllable externally of the cistern, can open this chamber (26) to the outlet, and there is a restricted passage (10, 49, 58, 88) between the chamber (26) and the interior of the cistern (1). On opening the pilot valve, water (and sometimes air under pressure) escaping the chamber (26) alters the pressure balance and the main valve assembly (2) lifts to generate the full discharge. The flow of water can help keep this valve assembly (20) lifted, and a low pressure zone in the discharge passage can be used to keep the chamber (26) scavenged. The valves close when the discharge is completed, and replenishment water penetrates the chamber (26) via the restricted passage (10, 49, 58, 88). <IMAGE>

Title: Diamond coated polymer devices for biomedical applications
Inventor: FRANKS DR JOSEPH
IPC: A61L29/10
Filed: 1995-03-15
Abstract: Improved polymer devices for biomedical applications such as catheters and other tubular inserts, breast implants and other biomedical devices are rendered biocompatible, smooth and easy to insert, non-irritant, less liable to encrustation, and less permeable by being coated with a DLC - diamond-like carbon - film, being chemically and/or physically bonded to the external surfaces of the devices by plasma assisted chemical vapour deposition system in which the DLC is deposited on to the polymer substrate in a vacuum reaction chamber using an RF supply typically at a frequency of 13.56 MHz. Alternatively the coating may be applied by sputtering a carbon target with energetic ions including argon ions by a dual ion beam or magnetron or ion enhanced deposition system; or by use of a hydrocarbon ionising beam source system. The substrate may be formed from polyurethane, latex, or silicone rubber. The DLC coating may be rendered conducting to allow an electrical potential to be applied to the coating to prevent bacterial colonisation on the catheter or other device surface, by incorporating a metal in the DLC coating by introducing a metal into the plasma from an evaporation source, sputtering source or other suitable metal source. Alternatively, a conducting film may be deposited on the polymer surface which is subsequently coated with DLC. Apparatus for coating a polymer with DLC is also disclosed and this comprises a housing 3 containing at least one cathode 2, a support means for the substrate near to the cathode, an electrical source connectable to the cathode, means for introducing into the housing a plasma including carbon ions 4, and control means for controlling the voltage applied to the cathode(s). <IMAGE>
