Title: Image run length coding and decoding
Inventor: MASON BRIAN R
IPC: G06T9/00
Filed: 1984-12-21
Abstract: A digitised video signal is compressed by a form of run-length coding which provides high definition edges and allows run-lengths to be at any video level. Portions of video at constant level are coded as a run-length code (at times t0, t2, t4) which is an 8 bit number with the most significant bit 1 and the remaining bits denoting the number of pixels in the run (up to t1, t3, etc). A special run-length code, all ones, denotes a run length to the end of the current line. At the end of a run, a pixel mode code (at t1, t3 etc) has most significant bit zero and the remaining bits denoting the number of ensuing pixel codes, such as codes 1 2 3 4 and 5 following t1. The pixel codes are any of the 8 bit numbers. The coded data is decoded by responding to a run-length code to maintain the digital values at the value established by the most recent pixel code for as many pixels as specified by the run-length code. On the other hand, when a pixel mode code is received the specified number of pixels are read out sequentially from the memory storing the compressed data. <IMAGE>

Patent GB-2192955-A (GB)
Title: Sealing glands
Inventor: SEWARD GAVIN JOHN
IPC: F16J15/54
Filed: 1986-07-25
Abstract: Sealing glands, such as those used for mounting and sealing the propellor shaft of boats powered by inboard motors, are conventionally either a single rigid tubular piece, or, and preferably, a three-part unit wherein a rigid gland both seals and supports the shaft, a rigid mount supports the gland, and a resiliently flexible pipe connects the gland and the mount together, making what is in effect a flexible unit. Both these units have their problems, which the invention seeks to overcome by proposing a one-piece, integral unit 17 that is fashioned out of a material that is intrinsically pretty rigid (i.e. cannot easily be deformed by applied forces) and yet which can be employed to make a shaped article the shape and dimensions of which allow that article to be, in a minor way, slightly resiliently flexible, and by then so shaping each end of the unit that each is rigid, and so shaping the middle of the unit (the part joining the two ends) that it has the desired limited resilient flexibility. Specifically, the invention suggests forming the middle of the tube, joining and integral with the two end sections 20, 21, as a thin-walled section 22 that is resiliently flexible by virtue of its thin walls, whereby the axes of the two end sections (the mount and gland) may be mutually displaced to a limited degree. <IMAGE>

Patent GB-870071-A (GB)
Abstract: 870,071. Electric measuring systems. VYZKUMNY A ZKUSEBNI LETECKY USTAV. March 6, 1959 [March 7, 1958], No. 7852/59. Class 40 (1). [Also in Groups XXXVI and XXXIX] Apparatus for measuring a voltage comprises a group of four toroidal coils wound as for a magnetic amplifier, associated with a cylindrical magnetic cover, a single-turn winding on the assembly producing an A.C. flux in the cylinder when one set of toroidal windings is energized, the interconnections between the windings being such that the test voltage applied to another set of windings upsets an initial electrical balance condition, energizing a motor which applies a torque to the cylindrical cover, thereby inducing a voltage in a solenoid winding by magnetostriction, which is used to rebalance the system. Construction (Figs. 1, 2). Four coaxial toroidal cores 11-14, each wound with five windings 21-51 &c., are arranged inside a magnetic cylinder 86 which is extended to form a narrow portion on which is wound a solenoid coil 10. The ends of the cylinder 86 are covered by plates 80, 82 interconnected by a rod 81 passing through the centre of the assembly. End-plate 80 is attached to a base-plate 8, and end-plate 82 carries a horizontal rail 84 on which a carriage 90 is located, movable by a motor 71 via a cable 6, the carriage carrying a pen 95 for recording its movement on a chart 99. Electrical circuit (Fig. 4).-Windings 21-24 are fed with A.C. to produce an alternating magnetic flux in each core 11-14, on which is superposed a unidirectional magnetic flux by windings 31-34. The end-plates 80, 82, the central rod 81 and the cylinder 86 form a single turn coupling with all the toroidal cores, and produces a cylindrical flux in the cylinder 86. When a D.C. voltage to be measured is applied to windings 51-54 it increases the flux in two cores, e.g. 11, 12, and decreases the flux in the other two cores, whereby the impedance of coils 21, 22 is decreased, and that of coils 23, 24 is increased, the unbalance between the pairs causing a current to flow through winding 710 of motor 71, which drives the carriage 90 and associated weights 93 to produce a torque on cylinder 86. Due to the magnetostrictive effect on the cylinder, a voltage is induced in pick-up coil 10 which is rectified at 220, 230 and flows through windings 41-44 to rebalance the circuit, the rebalancing being enhanced by the current in windings 61-64. Thus the distance travelled by carriage 90 is proportional to the voltage applied to windings 51-54, and is recorded on the chart 99. The apparatus may be used to measure a force applied to the rail at a fixed distance from the point of suspension, and automatically rebalancing as above by moving the carriage 90.

Title: Heat-sensitive microcapsular recording material
Inventor: FUJITA YUTAKA
IPC: B41M5/30
Filed: 1987-03-17
Abstract: Heat-sensitive recording material has, on a support (e.g. paper) a recording layer (or 2 layers) containing in a binder microcapsules separately containing a solution of a color former (preferably a diazonium salt), and a color developer component, and, outside of the microcapsules, particles of a color development accelerator (which may also be the color developer), (e.g. a hydroxy, carbamate, aromatic methoxy, organic sulfonamide, aliphatic amide or arylamide compound) which particles are covered with a wax or acrylic resin which does not lower the glass transition temperature of the microcapsule wall to 80 DEG C or less and has a melting or softening point of 50 to 150 DEG C. Color formation occurs by local heating of the material which allows permeation through the microcapsule walls; covering of the accelerator particles reduces fogging during storage, by keeping the accelerator from water in the layer.

Title: Level detector
Inventor: HAWKES HENRY WILLIAM
IPC: H03K5/1532
Filed: 1987-09-22
Abstract: This circuit detects when a rapidly time-varying waveform, minus any linearly superimposed DC component or similar relatively slow AC component, reaches a level corresponding to any selected fraction of its peak amplitude lying between its positive and negative peaks and including zero. A normaliser circuit 1 delivers a version of the input signal having an amplitude proportional to that of a reference signal r. After amplification, if necessary, in an amplifier 2, the signal is fed to first clipping circuit D1, R1, D2, R2, 3 arranged to produce a signal having cusps at the level to be detected. After further amplification, if necessary, in an amplifier 4, the cuspoid signal is fed to a further clipping circuit D3, R3 whose clipping level is dependent on the level of the reference signal r. The resulting output may be then shaped to produce rectangular pulses at the required points. <IMAGE>
