Title: Optical window
Inventor: AMON MAX
IPC: G02B6/00
Filed: 1985-06-14
Abstract: A window, for receiving a modulated beam of light, restricts the field of view of an optical system by total internal reflection. The window rejects the entry of unwanted radiation, such as noise, and comprises first and second triangularly shaped wedges 16, 20 of optical material. An entry face 36 of the first wedge 16 is perpendicular to a base plane 21, and its rear face 38 is at an acute angle to the entry face 36. An entry face 40 of the second wedge 20 is at the same angle to the base plane 21 as the rear face 38 of the first wedge 16, and the two wedges 16, 20 are separated by an air gap. Preferably, the rear face 38 of the first wedge 16 is contoured to reject incoming radiation from below the base plane 21, with comparable contouring of the adjacent faces of the first and second wedges 16, 20 permitting the entry of skew rays, to increase the directions in which desired radiation is admitted to the optical system.

Title: Liquid level monitor
Inventor: WILLIAMS ROY
IPC: G01F23/292
Filed: 1986-12-02
Abstract: A liquid level monitor includes at least one probe which is suspended in a casing to indicate when the level of a liquid 1 within the casing reaches the level of the probe 7. A flexible membrane 16 having a specific gravity higher than that of the liquid 1 contains a second liquid 17. As the level of the liquid 1 rises membrane 16 collapses and forces the liquid 17 into contact with the probe 7 to cause a switching action. The probe may be optical, electrical e.g. capacitative or resistive, or electromechanical e.g. a flat switch. The membrane contains a number of probes 7, is located within a tube 5 and can be reset by blowing air into it. The monitor is used to sense oil levels in engines and gear boxes and avoids false reading due to oil getting dirty and e.g. leaving a film on a probe. <IMAGE>
