Filed: 1985-01-28
Abstract: Apparatus for training in the rapid and accurate reaction to a situation confronting a trainee 12, a room 11, has one wall formed by a screen 14 onto which an image is back-projected by projector 16. Each gun 22 has emitter 24 responsive to its firing to simulate the projectile impact point by spot 26.

Patent GB-2175769-A (GB)
Title: Processing image data
Inventor: DOI TETSUO
IPC: H04N1/417
Filed: 1986-04-24
Abstract: The apparatus comprises: a data input/output circuit receiving and outputting binary image data and compressed code data; an encoding circuit 12 including (i) a first detecting circuit detecting transition points where the value of an input binary image data changes from one to another, (ii) an up-counter generating addresses of the transition points, and (iii) a second detecting circuit detecting if the value of the input binary image data does not change during a predetermined period whereupon the up-counter counts up faster than normal speed. The input image data is encoded into the output compressed code data by using line to line correlation, using the addresses of the transition points. The apparatus further comprises a decoding circuit 11 (Fig. 7) including a down-counter (31) presetting a run length of the input compressed code data and a third detecting circuit detecting if the run length exceeds a norm whereupon the down-counter counts down faster than normal, whereby the input compressed code data is decoded into the output binary image data. Data memories 7a,7b are controlled such that while one is in a write status, the other is in a read status, the write and read statuses being alternately changed for every line to read out or write the addresses of the transition points of a preceding line from or into one of the data memories and the addresses of the transition points of an encoding or decoding line from or into the other memory. A microprocessor, including program memories, selectively causes the encoding and decoding so that the data input/output circuit selectively receives or outputs binary image data and the compressed code data.

Title: Valve coupling
Inventor: IPSEN BERNT
IPC: F16L37/113
Filed: 1987-06-18
Abstract: A valve coupling for securing a valve in a pressure container, such as a keg of beer, comprises a neck ring (1) welded to the container, a valve (2) received in an opening in said neck ring, locking means (6) for securing the valve in the neck ring, and at least one gasket (9) to form a pressure- and fluid-tight connection between the valve and the neck ring. When the valve is dismantled, it is moved out of the neck ring in at least two steps. During the first one of these it is just allowed an axial movement which is smaller than the height of the neck ring, but sufficiently large for relief of the pressure in the container. This is by virtue of two axial grooves (14, 15) in separate parts of the valve which are engaged by circumferentially-spaced projections (16, 17) on the neck ring. <IMAGE>

Title: Sorting diamond bearing ore
Inventor: STEWART ANDREW DAVID GARRY
IPC: G01N21/87
Filed: 1989-05-05
Abstract: In order to sort diamond-bearing ore particles 2 conveyed on a wide belt 1, exciting radiation strikes the belt along an extended line. Diamonds are detected by passing the emitted radiation through a narrow band pass filter 9 and sensing the Raman radiation with a photo-multiplier tube 14. Only nearby axial-parallel rays passing through the filter reach the photo-multiplier tube. An array of side-by-side rectangular converging lenses 15 can be used, the ore particles being in the plane of the foci of the lenses. To stop rays having an angle of incidence greater than the maximum permitted, to avoid identifying non-diamond material as diamond, a further converging lens 10 is used to focus the rays at the plane of a telecentric stop 11. The position of the diamond can be detected for instance by a CCD array or by a time domain technique. The calibration of the apparatus can be monitored by detecting when the radiation from reference stones and holes on either side of the belt differs from predetermined values. <IMAGE>
