Title: Apparatus for detecting structural faults in materials
Inventor: JORDAN BARRY JOHN
IPC: G08B21/18
Filed: 1984-06-12
Abstract: The apparatus comprises a body (10) pivotally mounting therein a bell crank lever (38). The latter mounts at one end an external foot (48) for engaging with the material and at its other end presents an optical window (44, 46) normally disposed in a gap between aligned ends within the body (10) of fibre optic cables (24, 30).

Title: Method and apparatus for separating cast or extruded support blocks from workpieces
Inventor: WENDT ULRICH
IPC: B24B41/06
Filed: 1984-08-01
Abstract: Blocks of cast or extruded zinc, lead, antimony or tin alloys which surround portions of a workpiece, e.g. turbine blade blanks for convenient manipulation and support in a grinding machine are removed by cooling, e.g. by introduction into a liquid nitrogen bath. The material of the blocks is chosen to shrink at a higher rate and to extract a higher brittleness than that of the blades at the low temperature in the nitrogen bath. If the resulting internal stresses in the blocks do not suffice to effect their separation from the workpieces, the blocks are struck or scratched by a hammer or another suitable tool, either in or upon removal from the nitrogen bath. This initiates a disintegration of blocks without deformation or contamination of the workpieces. <IMAGE>

Title: A recirculating rolling ball transmission
Inventor: GREEN PAUL CLIFFORD
IPC: F16H1/16
Filed: 1984-09-18
Abstract: Power is transmitted from a drive shaft (1) to a driven shaft (2) by recirculating loose spherical balls (4) rolling in a spiral raceway formed between the shafts by spiral tracks provided in the circumference of gear members integral with the shafts. As shown, when the drive shaft 1 rotates it causes the loose spherical balls 4 to roll along the spiral track 1C in the outside of the drive shaft gear member and through the raceway formed by this track and a similar spiral track in circumference of the driven shaft gear member, and therefore, as the spherical balls progress along the spiral raceway the driven shaft is forced to rotate. To loose spherical balls are recirculated via passageway means 8, 9, 1D. <IMAGE>

Patent GB-2177863-A (GB)
Title: Impedance preserving amplifier
Inventor: MARSHALL CHRISTOPHER BRIAN
IPC: H03F3/191
Filed: 1985-07-08
Abstract: An amplifier has the characteristics that the impedance presented by the amplifier at its input is proportional to the impedance seen by its output and that the impedance presented by the amplifier at its output is proportional in inverse proportion to the impedance seen at its input. Thus from an impedance point of view the amplifier is transparent when inserted into a circuit such as a filter circuit as used in radio receivers. The amplifier can be implemented by two cascaded stages, each stage comprising a transconductor 32 connected in a closed loop with a second similar transconductor. <IMAGE>

Title: Facsimile pick-up device
Inventor: BERGQUIST FOLKE
IPC: H04N1/38
Filed: 1986-09-10
Abstract: A facsimile pick-up device comprises a linear array of photo-sensitive elements; when a limited region of a picture is scanned, only photosensitive elements corresponding to the region are used. In order to facilitate subsequent signal processing the number of photosensitive elements used should be equal to a power of 2. This is ensured by skipping some of the photosensitive elements evenly distributed along the length of array used-during scanning of the image. Figure 4 shows the effect obtained by skipping every third photosensitive element, whilst figure 3 shows the reproduction image which would be obtained if every photosensitive element were used. Distortion is avoided by reducing the number of lines scanned in the same ratio as the number of photosensitive elements skipped. <IMAGE>
