Title: Alignment of an ophthalmologic instrument
Inventor: IIJIMA HIROSHI
IPC: A61B3/14
Filed: 1995-10-25
Abstract: An ophthalmologic instrument such as a tonometer has alignment detection and correction by viewing an image of a subject's eye and an index image on a display. Illumination light is projected onto an anterior segment of the eye (E) from IR LEDs (21), and alignment light from another IR LED (31) guided to a cornea (C) through an optical system (30). Light reflected by the subject's eye (E) is imaged on a CCD camera (26) through an optical system (20) and an index image (SP) and anterior segment image (E') are displayed on a screen. The index image (SP) is also received by a sensor (45) connected to a comparator which detects information about alignment of the eye (E) with the instrument body. According to the comparator output, the display is changed to indicate when a desired state of alignment is nearing. Pressure in the eye is measured using a puff of air from a nozzle (18) and detecting the resulting deformation of the cornea with optical sensing system (50). A visible target light is projected onto the eye by optical system (10). <IMAGE>

Title: Hermetic seal for an optic fibre
Inventor: PLEYDELL MARK EDWARD
IPC: G02B6/42
Filed: 1996-01-23
Abstract: A hermetic seal for a fibre optic 12 mounted onto a component 11 with an aperture 11a has a sealant 14 which acts as a boundary between two media 15,16. The sealant 14 may be made from silver chloride or silver bromide or a mixture of both. The optic fibre 12 may be bare or have a jacket 12b and may have a thin metallic layer 13 between the fibre and the sealant 14. The metallic layer 13 may be silver or nickel. The sealant 14 may have a low viscosity in the liquid state allowing good seals with small clearances between the fibre 12 and component 11. The sealant 14 may have a low vapour pressure so that the seal does not offer an inherent source of contamination to a vacuum or other gaseous environment. The sealant 14 may have a degree of plasticity such that small changes in the dimensions between the parts due to thermal expansion can be accommodated without compromising the seal.

Title: Forming cylinder bores
Inventor: MIDDLETON IAN COROON
IPC: F02F1/18
Filed: 1996-03-02
Abstract: Cold distortion of an engine cylinder bore 2 is caused by the tightening of bolts 4 which secure the cylinder head and/or the crankcase to the engine block 10. Hot distortion is caused by uneven heating of the bore when the engine heats up to its normal running temperature. A method of forming an engine cylinder bore which is circular 8 in cross section when the engine is running at its normal operating temperature comprises machining the bore at ambient temperature to have a non-circular cross section so that hot and cold distortion cause the bore to become more nearly perfectly circular in cross section.

Patent GB-2305134-A (GB)
Title: Process and apparatus for removing hydroxide sludge from electrolyte liquid
Inventor: FREMBGEN FRITZ-HERBERT
IPC: C25F7/02
Filed: 1996-09-06
Abstract: The treatment of an electrolyte volume arriving from an electrochemical machining process and contaminated with hydroxide sludge is performed in a treatment basin (18) such that the contaminated electrolyte volume is supplied virtually horizontally to the surface of the clear electrolyte storage volume (30) contained in said treatment basin (18), and from this surface (28) electrolyte liquid is pumped away via one or several extraction points (32) for supply to a chamber filter press or centrifuge from whence the cleaned electrolyte is fed back into the treatment basin (18). The extraction of cleaned electrolyte from the treatment basin (18) takes place at a clearance distance from the bottom of said treatment basin (18), in the lower half of the basin or in the centre third of the basin (18) height and is pumped from the extraction point there to the electrochemical machining device (10). The electrolyte volume extracted from the liquid surface (28) of the electrolyte storage volume (30) contained in the treatment basin (18) is more heavily enriched with hydroxide sludge than would be the case following mixing with said electrolyte storage volume (30). In order to remove the hydroxide sludge, it is sufficient to extract a relatively small volume of electrolyte liquid per unit time. The chamber filter press or the centrifuge can thus be of smaller dimensions. The electrolyte (30) in the treatment basin (18) can be kept effectively clear. The treatment basin itself is of particularly simple construction.
