Patent GB-2161573-A (GB)
Title: Pin-jointed framework
Inventor: DE MORAIS ZOIO LUIS GONZAGA
IPC: E04H15/50
Filed: 1985-07-03
Abstract: The present invention relates to a framework (1) consisting of a suitable number of members (2) which, when jointed with one another by means of several axles or pins (3) form a lazy-tongs linkwork. The members (2) are articulated with one another at the joints and at the ends, showing a permanently curved shape or a flexibility which is sufficient to ensure a certain curving whenever the framework is mounted. The size of the framework depends upon the length and upon the number of the members thereof. The mounting of said framework is achieved by stretching the pin-jointed system until it reaches a pre-established limit. Once dismounted the whole system retracts, occupying a very small space. <IMAGE>

IPC: H01J23/087
Filed: 1986-01-30
Abstract: A coupled cavity TWT comprises a hollow copper tube 1 having a plurality of transverse walls 2 of iron which define cavities 3. The walls 2 each include an aperture 4 on the longitudinal axis of the tube 1 through which an electron beam passes during operation of the TWT.

Title: Remote protection of three phase distribution transformers
Inventor: HAMPSON JOHN THOMAS
IPC: H02H3/44
Filed: 1986-09-30
Abstract: It is desirable to provide remote digital protection of distribution transformers. A protection system is disclosed which is able to detect increases in transient D.C. current flowing in the respective phases of a distribution cable (10) feeding a transformer and also to detect increases in other selected functions of supply parameters for identifying and quantifying a fault current flowing in the distribution cable (10). Increases in these other functions are analysed to identify whether the increases indicate a fault current. Any such fault current can then be quantified and the triggering of a circuit breaker (19) initiated to isolate the supply cable on identifying a fault current. The circuit breaker (19) is not triggered for any increases in the other functions for as long as there is a detected increase in D.C. current in any phase.

Title: Screen
Inventor: RODGER MICHAEL D
IPC: A47K3/30
Filed: 1987-01-17
Abstract: A screen 1 comprises a sheet of flexible fabric material 2 folded over a rigid frame surrounding the sheet. The sheet of material 2 is in the form of a panel. The fold 3 on each edge of the sheet is formed by fastening each edge of the sheet to the body of the sheet e.g. by stitching 4. The frame comprises an elongate tube 5 on each edge. Each elongate tube 5 is rectangular in cross-section, and each tube 5 is of a size which enables the tube 5 to be inserted into a fold 3 to give a snug fit. The tubes 5 are connected together by connecting members inserted into the end of each tube 5, to form the frame. <IMAGE>

Title: Burner control
Inventor: NARUSE SHIGEO
IPC: F23N5/18
Filed: 1987-02-13
Abstract: A control apparatus for a gas burner (5) e.g. of a water heater comprises an electromagnetic proportional control valve (13) in a gas supply passage (11), a fan (6) for supplying combustion air to the burner (5), and a control circuit (14) for controlling the valve (13) and the fan (6) in dependence on the difference between a load temperature of the burner and a set temperature thereof. The circuit (14) directly controls the amount of air supplied for combustion by the fan (6). In response to the sensing of a change in the speed of the fan (6) or a change in the pressure, speed or quantity of air supplied, the valve (13) is correspondingly controlled to maintain the gas/air ratio. If the fan speed is measured by a tachogenerator, the output thereof may directly supply the valve (13). The arrangement avoids incomplete combustion caused by the valve responding before the fan. <IMAGE>

Title: Measurement of the lustre of a yarn
Inventor: WATSON COLIN HOWARD
IPC: G01N21/57
Filed: 1987-04-06
Abstract: A method of measuring the lustre of a moving monofilament or multifilament yarn 1 comprises illuminating the yarn with a beam of laser light 4, such beam being at an angle of 45 DEG  to a plane containing the yarn, and measuring the light which is reflected and scattered from the yarn in that plane over a suitable arc or subtended angle by means of one or more stationary sensitive devices 6. The light may be measured by a self-scanning photodiode array, a computer controlled photodiode array, a series of separate photodiodes or a vidicon-type tube.

IPC: G01N33/00
Filed: 1987-10-22
Abstract: A detector for detecting vapours which decompose on heating comprises a reference sensor 11 sensitive to a decomposition product of the target vapour, but insensitive to the target vapour, a heating element 13 to decompose the target vapour and form a convection current, and a working sensor 12 positioned in use in the convection current and sensitive to the decomposition product. The arrangement operates on a differential basis and requires no provision for sampling since it relies on convection currents. Each sensor comprises a pair of electrodes to measure the electrical conductivity of a chemically sensitive material therebetween which is sensitive to the decomposition product. Preferably the material is lead phthalocyanine, provided as a thin coating on an alumina substrate on which the electrodes are formed as interdigitated thin films. A heater is also provided on each substrate and the temperatures of the chemically sensitive coatings are maintained at predetermined values such that the sensitivity and speed of response of each sensor can be adjusted. The sensors are provided within an inert housing 10. <IMAGE>

Title: Thickness gauge for plastic film
Inventor: BAILIE TOM
IPC: G01B7/06
Filed: 1989-12-08
Abstract: The technical problem to which the invention relates is the economic measurement of thickness of films. The thickness of a plastic film (18) is measured by passing the film between two heads (10, 12) each comprising a first plate (20) and a plurality of second plates (22) which rest above the surface of the film (18), forming a series of capacitors. The individual capacitances of the series of capacitors are measured. A change in the thickness of the film (18) gives a proportional change in measured capacitance. Each capacitor may be included in a separate oscillator circuit and the oscillators energised successively, so as to obtain a scan of film thickness across the film. The plates (20, 22) may be moved out of the path of the film by rotation about an axis.
