Title: Eddy current flaw detector
Inventor: COPLEY DAVID CHARLES
IPC: G01N27/90
Filed: 1983-06-08
Abstract: Eddy current probe 3 is caused to scan a region 4 of a turbine engine blade containing a crack 9 and the probe output data after processing (21) and amplification (26) is plotted on a record at positions corresponding to positions on the blade scanned. The record may be produced by energising electrode pen (30) which produces heat to cause a burn mark on paper record (35). Probe (3) is located on one end of lever arm 40 to the other end of which is fastened pen (30). Since lever arm portion (40A) is greater than portion (40B) movement of pen (30) is greater than probe (3) to form a magnified mapping of the inductance changes of the probe. <IMAGE>

Patent GB-2155228-A (GB)
Title: Parking meter with advertisement carrier
Inventor: HENNIGES RUTH
IPC: G09F23/00
Filed: 1984-08-01
Abstract: The parking meter is provided with an advertisement carrier 20 comprising a frame 21 made from a resilient-elastic material (eg polyurethane elastomer or rubber), which has an advertisement carrier plate 25, 125 and a self-adapting profile corresponding to the shape of the upper parking meter casing wall. It also carries holding tongues 26, 27 laterally overlapping the parking meter casing 11 and which are connected to the parking meter casing side walls by means of adhesive-bonded joints. Due to the resilient-elastic construction of the advertisement carrier, the latter is protected against damage by bending, snapping off, etc. The pressure on impact action of the advertisement carrier follows the pressure or impact movement and then returns to its initial position when the pressure or impact action is removed. Thus, the full advertising effect is always retained and the parking meter casing is not destroyed. <IMAGE>

Patent GB-2160743-A (GB)
Title: Implantable tissue-stimulating prosthesis
Inventor: DALY CHRISTOPHER N
IPC: H04R25/00
Filed: 1985-05-23
Abstract: An implantable tissue-stimulating prosthesis, such as a cochlear prosthesis, which can be implemented in single-chip form, and permits great flexibility in stimulation strategy and data transmission format. Only sixteen electrodes are required for stimulating fifteen different sites. Each site is stimulated by a biphasic pulse under control of two adjacent electrodes whose polarities are reversed in the middle of the site stimulation cycle. Although the transmission scheme requires a pulse-width modulation format, the precise form of the format can be varied in order to accommodate widely different stimulation strategies. For example, only a single site may be stimulated during each transmission frame or multiple sites may be stimulated during the same frame. Although only one site can be stimulated at any instant of time, the system cycling is for fast that "simulataneous" site stimulations are perceived. The system is designed for minimum power usage, and its operation is fail-safe in that no site may be stimulated for longer than a pre-set time interval.

Patent GB-2177877-A (GB)
Title: Packet systems
Inventor: HARLAND GEOFFREY
IPC: H04L12/64
Filed: 1985-07-13
Abstract: In a packet switching system, e.g. a local area network, in which synchronous data such as voice or video traffic is handled, it is essential that measures be taken to deal with variable delays in transmission which could lead to loss of bytes which suffer excessive delay. In the present system, the reconstruction of a bit stream from received packets is controlled by time tagging of packets which taggings are noted at the receiving end, or by the use of a fixed or adaptive delay. Excessive packet delays, which cause loss of bytes, results in the lost bytes being substituted by the repetition of the previous byte, a zero byte, or one representing half the value of the previous byte.

Abstract: A lathe cuts the concave surface of the contact lens with a circular inner region having a part-spherical curvature for engagement with the eyeball, and an outer annular region having a part-spherical curvature with a larger radius of curvature than the inner region, to provide a degree of relief around the periphery of the contact lens. The lathe has a lower turntable (12) rotatably mounted about a central vertical axis (14) perpendicular to but intersecting the axis of rotation of the lens workpiece, a lower carriage (16) horizontally slidable on the lower turntable, an upper turntable (20) rotatably mounted on the lower carriage (16) about an eccentric vertical axis (22) and an upper cartridge (24) horizontally slidable on the upper turntable and supporting a cutting tool (30). The outer annular region is cut as the upper turntable rotates with respect to the lower carriage about the eccentric axis, and the inner region is cut as the lower turntable, the lower carriage, the upper turntable, and the upper carriage rotate about the central axis. The transition between the inner and outer regions is tangential. <IMAGE>

Title: Method and apparatus for non- destructively testing for discontinuities between a coating and a substrate
Inventor: STEVENSON GILBERT MCIVER
IPC: G01N25/72
Filed: 1985-12-18
Abstract: Discontinuities in adhesion between a substrate and a coating are detected by applying a temperature gradient across the substrate and coating 7, monitoring e.g. by infrared camera 9, the temperature over the surface of the coating 7, and dispaying the differences in the temperature over the surface of the coating 7 on a T.V monitor 10 or a film to indicate localised differences in the cooling rate of the coating 7 and hence the presence of air spaces associated with such discontinuities in adhesion. The coating may be formed by a heat shrink sleeve used to protect a pipe joint or it may be a magnesium, aluminium, zinc alloy cast around a steel substrate to form a sacrifical anode. In an alternative for testing a heat shrink sleeve coating a pipe, an elongate two part cylindrical casing hinged peripherally about a longitudinal axis has a plurality of spaced heat sensors e.g. thermistors which engage the sleeve and monitor its temperature. <IMAGE>

Patent GB-2181261-A (GB)
Title: Load indicating washer
Inventor: SINCLAIR ALASTAIR AITKEN
IPC: F16B31/02
Filed: 1986-09-29
Abstract: A washer device 3 is provided the elastic deformation of which under load causes a machined gap 6 between two circular projecting flanges 7 to reduce by a suitable degree. Between these machined surfaces and interposed in the gap, a shaped ring 8 can be freely rotated. Upon approaching the pre-determined load for which the device has been previously set the flanges 7 contact and bear upon the shaped ring 8 preventing its free rotation by hand. This serves as an indicator that a bolt 1 has reached its design load and that further tightening is not required. If a subsequent reduction in the clamping force takes place, this can be immediately detected as the ring 8 may again be freely rotated. The ring 8 may be adjusted by a set screw 12. <IMAGE>

Title: Laser angular rate sensor
Inventor: MARTIN GRAHAM J
IPC: H01S3/083
Filed: 1986-12-30
Abstract: A laser angular rate sensor has four mirrors (18 to 21) appropriately arranged at the corners of a square to reflect two oppositely directed laser beams around a closed path 17. Vibrators (22,23) interconnected with two adjacent mirrors (18,19) for effecting oscillation perpendicular to the mirror major surface are arranged to operate at 180 degree phasing. A vibrator drive circuit is controlled by actual mirror displacement to tune and maintain dither amplitude at a predetermined value which preferably is 0.271 of the laser radiation wavelength corresponding to the modulation index of the zeroth order Bessel function, Jo. The vibrator drive circuit incorporates the capability for dithering when the angular rate of input to the gyro is close to zero, but switches off for higher values. <IMAGE>
