Title: Cylindrical grinding machine
IPC: B24B5/01
Filed: 1981-01-19
Abstract: A cylindrical grinding machine comprises a grinding wheel arranged to move relative to a worktable in directions parallel and transverse to the axis of rotation of a workpiece. Control means provides for simultaneous movement in each direction, so that the shoulder and diameter of the workpiece may be ground in a single operation. Provision is also made for separate movement in each direction. By this means the rate of feed of the grinding wheel relative to the workpiece, in each direction may be varied infinitely, thereby accommodating varying circumferential surface/shoulder length ratios. The system also facilitates the grinding of contours on the workpiece. Means may also be provided for dressing the grinding wheel, such means comprising a diamond disc or single point cutter. <IMAGE>

Patent GB-2113636-A (GB)
Title: Improved roller reefing systems for sails
Inventor: RUSSELL ROBERT DENNIS
IPC: B63H9/10
Filed: 1982-01-05
Abstract: The invention provides improved roller reefing of sails, by using a reefing spar of varying wrapped circumference, or a sail of controlled thickness, or a specific combination thereof, to control sail shape, thereby eliminating all major sources of inefficiency which develop during reefing with conventional systems. Other options, beneficial to efficiency or safety, may be easily integrated. The sails may be on any device for taking power from the wind, where roller reefing could be used, but sailing boats are a primary application. Many different types of sail can benefit and the system can be applied retrospectively to existing spars. The aerodynamic efficiency of the sail is maintained, and may even be increased during reefing, so the system is compatible with high performance sails, and makes economic and practical reefing available to racing boats for virtually the first time. <IMAGE>

Title: Producing tubular bodies from flat flexible sheet materials
IPC: B31F1/00
Filed: 1982-01-29
Abstract: Equipment for forming tubular bodies from flat flexible sheet materials has a mould 1 against which the sheet material is shaped by compression means 2, 3 and 4. The sheet material enters the equipment at one end and is transported through the machine by conveyor belts 14, to leave the machine at the opposite end. An adhesive applying device 15 associated with the start of the belts 14 applies adhesive to one edge of the sheet material and the edges of the sheet, after forming of the tubular body, are compressed between tubular rollers 19, 20 to bond the edges of the sheet together. The rollers 19, 20 also assist in extracting the sheets from the equipment. <IMAGE>

Title: Surface inspection
Inventor: MULHOLLAND BERNARD EUGENE
IPC: G01M3/00
Filed: 1982-04-13
Abstract: A surface, particularly the inner surface (3) of a pipe (2) is inspected to enable surface interruptions caused by faults or joints or junctions to be detected and located, by means of a wheeled body (1) which is driven along the surface. The wheeled body is a remote controlled electric motor-driven construction having peripheral scanners (9, 10) which examine the surface (3) with infra-red radiation, and transmit data back to an interpretive control system. A number of separate scanners (9, 10) are disposed at different angular orientations around the direction of movement of the body so that information can be obtained as to the orientation of a detected surface interruption. A toothed wheel rotating in synchronism with the motor produces pulses to indicate the distance travelled. A light source 11 and detectors 12 respond to obstructions to stop the body. <IMAGE>

Title: Dual-flush cisterns
Inventor: BARRATT JOHN FRANCIS
IPC: E03D1/14
Filed: 1983-01-05
Abstract: A cistern attachment providing a dual flush facility for the siphon- discharge unit (not shown) of a w.c. cistern comprises a normally-open push-button air valve 3 shown fitted in the spare flush-lever aperture of the cistern wall 2, the valve 3 having an air inlet tube 10 which depends to a predetermined partial-flush level in the cistern. The valve outlet 8 is connected by a flexible pipe to an air- admission fitting inserted in the siphon bell above the full water line. Actuation of the flush lever (not shown) produces a discharge which ceases as soon as the cistern water level falls to the lower end of tube 10 and so admits air to break the siphon. For a full discharge the button 7 must be held depressed to close the valve throughout the flush. <IMAGE>
