Title: Selecting contact lenses for visual correction using photokeratogram
Inventor: KIVAEV ANATOLY ALEXANDROVICH
IPC: A61B3/04
Filed: 1982-11-06
Abstract: A method of selecting the contact lens using a set of trial lenses is disclosed, each of said lenses being characterized by the central radius of the optical zone, asphericity and toricity. Selection of the lens is founded upon the use of a photokeratogram to determine parameters of three rings (the three ovals shown being the images of these three rings on a cornea) pertaining to its adjusting mark, the thus obtained parameters providing for a choice of the appropriate contact lens with a high degree of accuracy, while reducing the number of repeated fittings in the patient's eye and simplifying the computation procedure. <IMAGE>
Patent GB-2110583-A (GB)
Title: Flame-cutting machine
Inventor: SCHMUNCK KARLHEINZ
IPC: B22D11/126
Filed: 1982-11-16
Abstract: During the cross-wise division of slabs (18) in continuous-casting installations, it is necessary to synchronise the speeds of the slabs (18) and the flame-cutting machine (10). This is achieved, even in the case of slabs with a small cross-section, by placing the burner-carriage running track (42) on the slab (18) only partially in terms of its load, specifically via an adjustable amount. The track 42 is suspended from spring assemblies 28. Motor-driven pinions 34 drive, via racks 36, blocks 26 fixed to the track to raise and lower it. The spring assemblies 28, acting between the racks 36 and guides 22 on the machine 10, are compressed by upward movement of the racks 36 caused by continued rotation of the pinions after a portion 40 of the track 42 has contacted the slab 18. The degree of compression and thus the load applied is varied by the setting of a switch 46 which turns off the motor driving the pinions. <IMAGE>

Title: Breathing device having irreversible moisture indicator
Inventor: MCKEE ELMER S
IPC: A62B9/00
Filed: 1983-04-05
Abstract: An emergency breathing device comprises an oxygen-emittive moisture-reactive chemical substance contained within a canister (40), a retractable mouthpiece assembly (36), and a breathing bag (38). In use, moisture exhaled by the user of the device reacts with the oxygen- emittive substance to produce oxygen. The device has an indicator which irreversibly and visually indicates whether moisture has at any time infiltrated into the interior of the breathing device to detrimentally affect the oxygen-emittive capacity of the chemical substance. Potassium superoxide is disclosed as both a preferred oxygen-emittive chemical substance and as a preferred moisture-indicator medium. <IMAGE>
Patent GB-2138193-A (GB)
Title: Token-operated apparatus
Inventor: ROBERTS JOHN ARTHUR
IPC: G07F7/00
Filed: 1983-04-16
Abstract: The apparatus causes a meter, e.g. a gas meter, to allow a predetermined quantity of a commodity to be delivered. A key token (21) is inserted into a keyway, so that its tip engages a lever (9). Rotation of the key token then carries lever (9) around, together with pin (11), which urges a driving tooth (39) into engagement with a quantity wheel (30). Further rotation of the key token results in the tip snapping off at weakened section (40), and the key shank is then removed. Rotation of manual handle (20) now drives the quantity wheel through tooth (39) around a predetermined arc, the quantity wheel in turn driving a meter credit mechanism (not shown). Return of the handle to the initial position frees the key tip and this disengages the tooth (39) from the quantity wheel. Previous coin-operated mechanisms can be replaced by this token-operated apparatus avoiding problems associated with the collection of money. <IMAGE>

Patent GB-2134062-A (GB)
Title: Link belts
Inventor: LORD RICHARD THOMAS GEOFFREY
IPC: D21F1/00
Filed: 1984-01-18
Abstract: The invention proposes the use, in the manufacture of link belts, of helical coils wound from elongate synthetic plastics material of non-circular, and preferably generally rectangular, transverse cross-section, the major dimension of the said cross-section extending widthwise of the link belt. By using, for example, flat monofilament yarns of a given cross- section in the production of an oval coil of a related major dimension it is possible to increase the cross-section of the wire receiving tunnel formed by two interdigitated coils without prejudice to the capability of interdigitated coils to remain in mutual engagement, and thus facilitate the introduction of hinge wires by mechanical means.

Title: New bleachable dyes for use in photographic assemblies
Inventor: POSTLE STEPHEN RODERICK
IPC: C09B23/06
Filed: 1984-03-29
Abstract: Bleachable dyes are described of the general formula I:-      (DYE<m+>)n      (PUS<n->)m  of the general formula:-      (DYEG)n      (PUSG)m wherein (DYE<m+>) or (DYE<m->) is the cation or anion of a water-soluble ionic dye (preferably of the heterocyclic methine type) which is bleachable in a photographic processing solution and (PUS<n->) or (PUS<n+>) is the counterion of the dye and is a photographically useful species, and m is the anionic valency of the dye and n is the ionic valency of the counterion, the size of the counterion being sufficient to render the dye water-insoluble. By "photographically useful species" is meant either a compound which when the compound of formula I or II being present in a photographic assembly is bleached during photographic processing to release the PUS component and form a PUS compound, the PUS compound acting beneficially on the photographic assembly. Alternatively the PUS compound may be another dye which serves to render the water-soluble dye insoluble and also to alter its absorption characteristics in a way which is beneficial to the photographic assembly.

Abstract: Thin walled containers, preferably beakers of plastics material, intended to be fitted together into rod-like stacks and which, in the stacks, form between the bottoms of adjacent containers, respective chambers to accommodate filling, for example powdered coffee, are provided in the peripheral wall with a stacking ring 15 and a holding ring 16. The holding ring 16 is constructed with two superposed annular parts 16a, 16b of which, in the stack, one annular part 16a of a container is opposite the other annular part 16b of the adjacent container. Constructed in the annular parts 16a and 16b are peripheral rows of cap-shaped projections of which the projections 19 of one peripheral row protrude towards the interior of the container and the projections 20 of the other peripheral row project towards the outside of the container. When the containers are fitted together in the stack, the projections 19 and 20 which are in an oppositely disposed relationship are impressed partially and resiliently into one another so creating a reliable grip which can be reliably and smoothly overcome by the application of limited axial force when the containers are to be moved apart in an axial direction. <IMAGE>
