Title: Coding a video signal using constant and non-constant luminance principles
Inventor: ROBERTS ALAN
IPC: H04N9/79
Filed: 1994-03-21
Abstract: In a television camera, for example, linear colour components R, G, B signals are generated by a colour correction matrix 2 from camera colour component signals r, g, b. The linear colour component signals are passed through a non-linear gamma processor 4 and a coder 6 to form conventional, non-constant-luminance luminance and colour-difference signals Y', U', V'. The colour-difference signals are low-pass filtered by a channel filter 8 for transmission. The linear colour component signals R, G, B are also passed through a coder and a gamma processor 12 to form a non-linear constant-luminance luminance signal YCL'. The non-constant-luminance and constant luminance luminance signals Y' and YCL' are then respectively low-pass and high-pass filtered by filters having complementary gain-frequency characteristics, and added by an adder 18 to form a combined luminance signal for transmission or recarding.   <IMAGE>

Title: Monitoring vertical movement of structures
Inventor: BELLINGHAM PETER JOHN
IPC: G01C15/00
Filed: 1994-12-23
Abstract: Vertical movement of buildings or civil engineering structures (25) is monitored by scanning a laser (11) in the horizontal plane. Retro-reflecting prisms (24) fixed at various locations on the structure reflect the laser beam back onto a vertical photodetector array such as a CCD strip (12) positioned adjacent to the laser. Signals from the array indicate any vertical displacement of a prism relative to the laser. The laser is positioned at a datum point (22) and a drive motor (14) rotates the laser to perform the scan.

Title: A method for multiplying the frequency of a digital signal and a frequency multiplier circuit
Inventor: LAINE SEPPO
IPC: H03K5/00
Filed: 1994-06-15
Abstract: The invention relates to a method for multiplying the frequency of a digital signal by a predetermined multiplier and a frequency multiplier circuit. The method comprises generating from an input signal (CLK1) of a first frequency an output signal (CLK3) of a second frequency, the ratio between said frequencies corresponding to said frequency multiplier. In order that clock frequencies higher than the basic clock might be avoided and that the phase variation of the signal of the multiplied frequency might be controlled, a predetermined number of pulses is generated in the output signal (CLK3) per one transition of the input signal (CLK1), and additional pulses (E) are added to the output signal thus generated at predetermined intervals in such a manner that the additional pulses are generated at predetermined positions in relation to the pulses generated in response to said transitions. <IMAGE>

Title: Framework for e.g. airships
Inventor: HAGENLOCHER KLAUS
IPC: B64B1/08
Filed: 1996-04-04
Abstract: The invention relates to the production of extremely light supports which are, however, capable of being subjected to high load and which are formed as a framework. Areas of application for supports of this type are predominantly found in the field of air travel, but also in other areas of technology where it is intended that framework supports, being large volume components, should have as little weight as possible. For the production of framework supports of this type from thin-walled pipes there are provided sleeve connections which are formed such that the pipes which are to be connected at one framework junction are covered in a form-locking manner by means of sleeve parts of a sleeve connector, which sleeve parts may be adhered in series to the junction, wherein the entire junction, together with all the pipes which open out at this point, is surrounded by parts of the sleeve connector.

Title: Removing iron particles from coolant liquids
Inventor: MAWER DAVID JEFFERSON
IPC: C02F1/52
Filed: 1996-09-12
Abstract: A method of treating a coolant liquid used in rolling mills 2, 3, or for continuous casting and contaminated with particles of scale, comprises passing the contaminated liquid through a primary settling zone 11, retaining the liquid in the zone until all particles of scale having a particle size greater than about 200 ~m have settled out, passing the supernatant liquor through a region 13 of constant magnetic field under streamline flow conditions thereby to coagulate iron-containing particles in the liquor and enhance sedimentation of resulting coagulated particles, and collecting the treated liquor now containing less than about 50 ppm solids by weight for reuse.

Patent GB-2319822-A (GB)
Title: Hydraulic boosting device
Inventor: SHIMADA MASAHIRO
IPC: B60T13/14
Filed: 1997-11-18
Abstract: In a hydraulic boosting device for brakes, when the pressure in an emergency accumulator 9 is less than a set pressure, a stepped piston 70 moves downward to seat throttle valve 72 on seat 71 so as to restrict flow of hydraulic fluid from a pump to inlet path 14 and to develop a fluid pressure in annular path 73 and in paths 69 and 31 leading to the accumulator. When the pressure in the accumulator exceeds the set pressure, it acts on the stepped piston 70 to move the throttle valve 72 away from its seat so that flow to the inlet path is no longer restricted. In normal operation, valve 43 controls admission of fluid pressure to chamber 23 to act on booster piston 24. On pump failure, emergency valve 36 is operated to open communication between the accumulator and the pressure chamber.

At least one ambient temperature of the system is also taken into consideration in determination of the criterion, in that the ambient temperature and/or a magnitude dependent thereon is or are detected and processed in a signal-processing arrangement (36).
Patent GB-2335915-A (GB)
Title: Conveying flowable materials
Inventor: MARKS DAVID ALEX
IPC: G01G13/24
Filed: 1998-04-01
Abstract: An apparatus for supplying fluent materials eg from a hopper 11 includes a primary means eg conduit 13 for supplying flowable materials to a measuring device eg weighing device 14, means for controlling said flow eg control valve 12 from the primary means to the measuring device in response to the measuring device, additional means 21 to divert the flowable materials from the primary supply means to an additional supply means 22, and means 23,24,25 to control flow from the additional means to the measuring device in response to said measuring device. In use, material from a primary supply flows through the primary control valve 12 until a predetermined weight, being less than the target weight, at the weighing device 14 causes a control signal (control 1) to be sent to close said primary valve. During passage of the material from the primary supply to the weighing device some material is diverted via an additional supply conduit 21 to an additional supply store 22. A control signal (control 2) from the measuring device operates a motor 25 to drive an auger 23 thereby allowing material to flow from the additional supply until the target amount to be measured at the weighing device is reached. In this way, high flow rates can be achieved by the combination of coarse control via the primary supply means and fine control via the additional supply means.
