Title: Coherent optical processing apparatus
Inventor: STEELE ROBERT JOHN
IPC: G06E3/00
Filed: 1988-04-28
Abstract: Two input images are formed from arrays (Figs 2, 3) of pixels by arrays of electro-optical transducers (12) such as SLM's illuminated by a laser (10) and collimator (11), each array of pixels comprising sub-arrays corresponding to different bit weights. The sub-arrays of one array are time-domain modulated in sequence by an array of shutters (13). The sub-arrays of the other array are amplitude modulated, again in accordance with bit weights, by an array of attenuators. A filtering operation is implemented by a filter (16) in the Fourier plane between two lenses (15, 17) and the filtered image is reconstituted by arrays of detectors (19), e.g. CCD's and an output processor (25) which sums the weighted bits pixel by pixel. After each shutter (13) has been opened a Fourier plane image has moreover been written into a non-linear device (21) with memory, via another lens 20. This image is read out by another laser (27) of different wavelength, collimator (28) and lens (22) to form convolution and cross-correlation functions at an output plane. An array of detectors (23) at this plane detects the cross-correlations, between the sub-array selected by the shutter (13) and the sub-arrays of the said other array. The detectors (23) e.g. CCD's integrate the cross-correlations over the sub-arrays of the said one array and an output processor sums the weighted bits pixel by pixel to produce an image representing the correlation between the two input images. <IMAGE>

Patent GB-2219474-A (GB)
Title: Gold leaching
Inventor: MOBBS DAVID BARRY
IPC: C22B11/08
Filed: 1989-05-05
Abstract: Leaching of gold-bearing solids, such as crushed lean ores or material recovered from very old waste tips can be carried out with a dilute aqueous alkali cyanide solution, but the extent and/or rate of recovery of gold is impaired by the anaerobic or reducing conditions that can exist in such heaps, and especially towards their base and or by poor supply of oxygen in agitation leaching. The rate and/or extent of gold recovery in heap leaching can be increased and the supply of oxygen simply controlled by slow release in agitation leaching, using otherwise identical conditions by employing an effective amount of a slow dissolving poorly soluble solid metal peroxide, either by incorporating it within the heap or in the mixture of gold-bearing solids and lixiviant. The peroxide is advantageously calcium peroxide because it is not only very effective but also is environmentally suitable. The amount employed is preferably from 1 to 10 parts w/w per 1000 parts of gold-bearing solids for the low grade material, usually containing from 1 to 10 g gold per tonne solids.

Title: Travelling bread ovens
Inventor: JAMES CHRISTOPHER DAVID
IPC: A21B1/42
Filed: 1989-05-05
Abstract: A method of baking bread in an oven comprising applying a relatively high initial heat flux e.g. 375 DEG C to the dough in a first or front section of the oven while the surface of the dough is moist and then reducing the heat flux e.g. below 200 DEG C to a level insufficient to burn the surface of the dough, but sufficient to maintain heat transfer to the dough, the heat flux after the first section should still be sufficient to maintain the rate of temperature increase at the centre of the loaf. It has been found that this rate can be maintained even though the heat flux applied to the loaf is substantially reduced.

Title: A method and device for cutting a glass tube into pieces
Inventor: BORGI LUIGI
IPC: C03B33/06
Filed: 1989-07-31
Abstract: The method and device are of the type in which a continuous glass tube (T) moves along its own axis (X) at a given constant linear velocity (Vs) and a rotary cutting tool (60) is used to effect the cutting and is provided with a cutter (62) which travels along a circular orbit (O) lying in a plane (P) inclined to the axis (X) of the tube (T). In one segment of its orbit, the cutter (62) intersects the outer surface of the tube (T) which is cut upon each rotation of the tool (60) whilst the tool is driven at such an angular velocity ( omega s), termed the synchronism velocity that its cutter (62) has a linear component (Vs) of the velocity of the tube (T). The tool (60) is rotated by its own variable-speed motor. The motor imparts the synchronism velocity ( omega s) to the tool (60) for a minor fraction (I) of each revolution, which includes the said segment (S) of the orbit of the cutter (62). For the remaining, major fraction (II-III) of each revolution, however, the motor imparts to the tool (60) an angular velocity ( omega ) such that, during its next revolution, the cutter (52) reaches the said orbit segment (S) when the tube (T) has travelled the predetermined distance (Lt) from the incision made in the preceding revolution. The operating cycle of the variable-speed motor is preferably controlled by a numerical control device on which the predetermined length (Lt) of the pieces is set manually. <IMAGE>

Abstract: PCT No. PCT/GB88/00324 Sec. 371 Date Oct. 23, 1989 Sec. 102(e) Date Oct. 23, 1989 PCT Filed Apr. 27, 1988 PCT Pub. No. WO88/08290 PCT Pub. Date Nov. 3, 1988.A physiotherapy device for treating spinal disorders comprises a body (6) housing actuating rams operating on pistons (14) which carry feet (15). The pistons (14) are caused to reciprocate so that while one diagonal pair is raised, the other will be lowered and vice versa. The device is applied so that the feet (15) rest on the lateral ends of transverse processes to either side of a pair of adjacent vertebrae. The reciprocating motion of the feet (15) then causes a counter-rotational movement between the pair of vertebrae being treated. This can be used to help to relieve a loss of mobility between the joints of the spine. In an alternative use blows are delivered rapidly by the feet (15) so as to trigger natural stretch reflexes which will cause the vertebrae to be brought back into normal alignment from an abnormal displaced condition.

Title: Magnetic reproducing apparatus
Inventor: TAKEDA MUNEHISA
IPC: G11B5/588
Filed: 1990-09-28
Abstract: Magnetic reproducing apparatus of the helical scanning type is provided such as in a videotape recorder and a DAT (Digital Audio Tape) Recorder, in which a magnetic head (5) is controlled so as to move perpendicularly to its scanning direction to fit the undulation of a recorded track. For this controlled movement, the apparatus includes a reference signal storage for storing a head displacement signal, which is produced by a head-moving signal operating unit (22), as a reference signal during the next operating cycle. With this arrangement of controlling the movement of the magnetic head (5) for every recording track, it is possible to correct displacement about a position of a magnetic head based on the reference signal and an accumulation of displacement signals from previous scanning cycles, thus giving convergence of displacement and so improving the quality of signal output from the apparatus. <IMAGE>
