Patent GB-2230623-A (GB)
Title: Fuel rate control for heating appliance
Inventor: HOLLINS HUMPHREY BOLTON
IPC: G05D23/20
Filed: 1990-03-19
Abstract: The temperature of fluid supplied to a circulating fluid heating system by a fuel burning heating appliance is monitored, and the rate of change of the monitored temperature is measured. The rate of fuel supply is adjusted in dependence upon a comparison of the measured rate of change with a predetermined rate of change such that the rate of fuel supply decreases with increasing measured rates of change thus reducing cycling. The rate of change may be calculated over different sampling periods. The predetermined rate of change may be a function of the measured temperature, and perhaps of the outside temperature. The rate of fuel supply may also be reduced progressively in stages as the temperature of the fluid supplied to the system or the temperature of a room heated by the system passes preset thresholds. <IMAGE>

Title: DATV coding of high definition television signals
Inventor: THOMAS GRAHAM ALEXANDER
IPC: G06T9/40
Filed: 1990-11-05
Abstract: In a DAVT HD-MAC system using 80ms, 40ms and 20ms coding branches, in the 80ms branch, instead of taking one quarter of the samples from each of four fields or all the samples from one field in four, half the samples are taken from half the fields, considered in pairs. The information is described as derived from a sequential image co-timed with one field and is transmitted in two adjacent fields. A "spot-wobble" technique due to estimated motion vectors may be employed. The new signal is compatible with first-generation DATV receivers while providing an improved picture on second-generation DATV receivers. <IMAGE>

Title: Trailer hitch lock
Inventor: STEELE DUNCAN ANDREW
IPC: B60D1/60
Filed: 1992-07-10
Abstract: A trailer hitch lock 1 has a square section solid steel obstruction bar 2 housed in a square section steel sleeve 3. The sleeve is bolted with frangible head bolts 5 to lie along the underside of a trailer drawbar 6. The draw bar carries a conventional ball hitch 7. The obstruction bar 2 and the sleeve 3 are provided with through bores 8, into which can be engaged the pin of a padlock 9, to lock the position of the obstruction bar 2 longitudinally of the drawbar 6. In use, the obstruction bar is locked in a position such that its front end 10 extends close beneath the socket 11 of the hitch. The bar thus obstructs the socket and prevents a ball from being introduced into it. The trailer then cannot be connected to a towing vehicle and towed away without authorisation. <IMAGE>

Title: Nuclear fuel pellets
Inventor: MOORE FREDERICK JOHN
IPC: B01J2/22
Filed: 1992-12-18
Abstract: A method and apparatus for producing nuclear fuel pellets in which nuclear fuel material is compacted to form pellets that are subsequently sintered.

Title: Multi-passband,dielectric filter construction
Inventor: AGAHI-KESHEH DARIOUSH
IPC: H01P1/213
Filed: 1993-04-19
Abstract: A filter duplexer (280), such as a filter duplexer for a radio transceiver, of minimum dimensions is disclosed. A first filter portion (304, 308, 312, 316) of the duplexer filter includes resonators of at least a first geometric configuration, and a second filter circuit portion (320, 324, 328, 332, 336) of the duplexer filter comprises resonators of a second geometric configuration. The geometric configuration of the two filter circuit portions are dissimilar, and the relative characteristic admittances of the resonators of the respective filter circuit portions are dissimilar. Because the resonators of the two filter circuit portions are of dissimilar electrical characteristics, a desired frequency response of the duplexer filter may be obtained with similar loading capacitances. <IMAGE>

Patent GB-2292187-A (GB)
Title: Propulsive mechanism
Inventor: RAYNER JOHN PETER
IPC: B63H7/00
Filed: 1994-08-11
Abstract: A centrifugal propeller 10 or 11 within a specially shaped housing, 12, is rotated by a fuel-powered motor connected to spindle 15, and thus generates an airflow. The generation of this airflow produces a reactive force on the propeller and its housing. This force will be transmitted to any object, such as a vehicle, boat, or aircraft, to which the propeller is fixed. The direction of the reactive force, and therefore of the transmitted force, is determined by the direction of the airflow, which may be varied (eg by means of vanes or a rotatable housing) during use. The strength of the transmitted force may be varied during use by control of the speed and volume (or mass) of the airflow. <IMAGE>

Title: Adjusting the rate of application of printing energy in response to change of resolution of a thermal stencil cutter.
Inventor: YOKOYAMA YASUMITU
IPC: B41J2/355
Filed: 1995-03-01
Abstract: A thermal imaging arrangement of the kind in which a line-print-head spans the width of a sheet or web to be imaged so as to record a whole line of image points at a time, and in which the sheet or web is indexed past the print head so that the pitch from line to line is determined by the substrate movement between successive point imaging operations, characterised in that:-   (1) the arrangement is adapted to print with at least two different selectable line pitch resolutions by use of respective different substrate feeding rates, (2) the heating elements, as measured in the direction of indexing of the substrate, are shorter than the minimum selectable line pitch (greatest selectable resolution), (3) the rate of application of printing energy (controlled either by reducing the printing energy per point imaged, or by increasing the interval between successive point imaging operations) is reduced in response to an increase in line pitch resolution (reduction of interline spacing).   The pitch of image points along a line is dependent upon the print head construction, and remains unchanged. The smallness of the printing elements w.r.t the line pitch ensures that discrete ink conducting holes are formed in a mimeograph stencil. The variation of print energy application rate with resolution tailors the size of the holes to ensure high print density printing under all available resolutions (e.g. from 300 to 400 dpi in the stencil transporting direction as shown in Figs 18A and 18B) without the ink conducting holes coalescing together when the highest resolution is selected. The printing energy may also be adjusted in response to accumulated heat in the print head (as measured by a sensor associated with the head); the nature (e.g. fluidity) of the ink, and the temperature of the ink (as measured by a sensor in the ink reservoir). The heating energy per point imaged may be adjusted by altering the current, or the width of the printing pulses, or by the incorporation (or elimination) of subsidiary pulses subsequent to each main pulse. <IMAGE>
