Title: Line scanners
Inventor: KOETSER ADRIAN HARRY
IPC: H04N3/08
Filed: 1984-09-28
Abstract: Line scanners which employ a rotating reflective polygon 32 to sweep an image of a viewed scene 31 across one or more detector 33 suffer from image distortion towards the edges of the field of view. This problem may be mitigated by arranging firstly that the signal output by the detector be sampled, instant by instant, each sample representing a digitized dot-like portion of the viewed scene, and secondly that the sampling be at such a rate as exactly counteracts the linear distortion, so that as the linear distance on the ground increases - as the angular spacing of the instantly viewed area from some central datum line increases - so the sampling rate increases in correspondence (and thus the number of dot-like portions increases to match the greater extent of the scene). In addition the output of the line scanner may be stabilised against lateral angular movement (roll) of the scanner by sampling each line for a time that is shorter than the time needed to scan the maximum field of view so that the scanner output constitutes a window on to that maximum field of view, the initiation time of the sampling for each line being changed thereby moving the window to counteract any roll of the scanner. <IMAGE>

Title: Convertible cradle
Inventor: CASSIDY JOSEPH GREGORY
IPC: A47D7/00
Filed: 1984-10-18
Abstract: End panels or supports 10 each have linear resting surfaces 16 and convexly-curved rocking surfaces 18 and are connected by longitudinal members 20 which form part of or carry a mattress or bedding carrier 22. When resting on the linear surfaces 16 and with side frames 28 extending upwardly, towards surfaces 18, the structure is a stable (i.e. non-rocking) cradle or cot. When inverted to rest on the surfaces 18 and the side frames 28 again extending upwardly towards surfaces 16, having been swing about the axes of members 20, one has a rockable cot (Fig. 4). When resting on the linear surfaces 16 and with one of the side frames extending upwards and the other extending downwards (Fig. 5) one has a stable seat or bench, and this can be inverted to rest upon the surfaces 18 when one has a rockable seat or bench. <IMAGE>
Patent GB-2167269-A (GB)
Title: Loudspeaker
Inventor: EXTANCE PHILIP
IPC: H04R23/00
Filed: 1984-11-21
Abstract: An optical transducer, e.g. for a loudspeaker, has a large area photocell (7) close to and parallel to a thin metallised diaphragm (6), the diaphragm forming the closure for a hole in a silicon wafer (3). The metallisation is integral, via the sides of the hole, with metallisation (5) underlying the wafer. Below the metallisation there is a thin silicon layer (2) on a glass substrate (1). Light modulated with an acoustic signal is aimed at the underside of the photocell, which thus generates a voltage which by repulsion oscillates the diaphragm. The transducer can be at the small end of an acoustic horn. <IMAGE>

Title: An a amylase assay method and reagent kit
Inventor: BLAIR HENRY E
IPC: C12Q1/40
Filed: 1985-07-26
Abstract: An  alpha -amylase assay method is described together with a reagent kit for use therein. An oligosaccharide substrate for  alpha -amylase is provided. The substrate contains at least 3 glucose units. Its reducing-end glucose unit is bonded, via a bond cleavable by  alpha - or  beta - glucosidase, to a label which exhibits an optically measurable change upon cleavage of the bond. Its terminal glucose unit is bonded to a blocking substituent which inhibits cleavage by exo-enzymes of the bond between the terminal glucose unit and the adjacent glucose unit. A liquid assay sample is contacted with the oligosaccharide substrate and with an exo-enzyme capable of cleaving the bond between the reducing-end glucose unit and the label. The optically measurable change is used as a measure of  alpha -amylase in the sample.

Title: Marking machine
Inventor: LUNN ALAN JOHN
IPC: B44B5/00
Filed: 1985-09-12
Abstract: A marking machine of the kind in which a workpiece is indented with the required mark by means of a die (shown in broken lines), the die being of arcuate or cylindrical form and the operation of marking a workpiece involving two successive movements, a first movement to bring the periphery of the die into engagement with the workpiece and a second movement, being a rotational movement of the die, to bring about the required marking as the die and workpiece move together in engagement. So that the speed of operation can be increased and operator fatigue reduced, both movements are brought about by a single manually operable lever 32 and during successive arcs of movement constituting a single operative stroke of said lever. Preferably a lowering cam 28 is mounted on the shaft 16 of lever 32 which shaft also carries the die. <IMAGE>

Title: Railway monitoring system
Inventor: BARNARD ROBERT EDWARD BLAKE
IPC: B61L1/14
Filed: 1988-10-27
Abstract: A system for monitoring the passage of trains on a rail track by measuring train length, employs track circuits which detect the presence of any part (wheel axle) of a train in any part of the track-circuit. A distance indication of the overlap of train and track-circuit is provided by an axle-driven pulse counter on the locomotive AND-ed (23) with the track-circuit 'presence' output, which is transmitted (15-19) from the trackside. Knowledge of the track-circuit length L1, either stored on the locomotive or in a central control station (31), or supplied at the time by the radio link from the trackside, enables the train length L0 alone to be deduced. This train length count is then compared at successive track circuits terminating block sections to give an indication of any discrepancy and the possibility of a carriage having been left in the section. <IMAGE>

Title: Method of processing seismic data
Inventor: BEASLEY CRAIG J
IPC: G01V1/36
Filed: 1989-02-10
Abstract: A computationally-economical method is disclosed for converting a set of aerially-distributed seismic traces into a new, clearly-resolved, three-dimensional display of a volume of the earth without use of dip-dependent or azimuth-dependent migration velocities. An array 34 of receivers is grouped in cells 42, for either land or marine application, in combination with a seismic source 40. Stacking of the received data is based upon a best estimate of the RMS velocity. Each trace receives normal-moveout correction for the source to receiver distance prior to stacking. The corrected traces are then weighted to compensate for geometric spreading between source to receiver pairs and the resultant traces are altered by a moveout coefficient which is a function of the distance between the plurality of cells into which each trace is to be stacked and the midpoint between the source and receiver for that trace. This alteration and a frequency content limitation are carried out according to particular formulae, which are disclosed. <IMAGE>
