Title: Microstrip patch antenna
Inventor: EVANS DAVID HILLARY
IPC: H01Q9/04
Filed: 1990-05-23
Abstract: A microstrip patch antenna comprises a substrate (1) supporting at least one patch element (2). A spatial variation is obtained in the radiation pattern of the patch element (2) by tapering the width (W1 to W2) of the element. This provides a further degree of freedom for adjusting and controlling the radiation pattern from a small array of patch elements (2). In one example, a 2 x 2 array of tapering element shapes is symmetrically arranged on the substance (1) as a feed for a prime aperture such as a lens or a reflector. The ends of the patch element(s) (2) may be laterally displaced to skew the radiation pattern. <IMAGE>

Title: Plural tobacco streams
Inventor: HEITMANN UWE
IPC: A24C5/18
Filed: 1990-06-15
Abstract: A single stream of comminuted tobacco leaves is divided into two discrete streams each of which contains a surplus of tobacco particles. The surpluses are removed by discrete trimming devices and the thus removed surpluses are conveyed into the distributor which forms the single stream in such a way that the surplus which is removed from one of the discrete streams is reused for the making of a next-following portion of the one discrete stream or for the making of a next-following portion of the other discrete stream. The surplus which is removed from the other discrete stream is reused for the making of a next-following portion of the other discrete stream or for the making of a next following portion of the one discrete stream.

Title: Friction depending lubricants,such as automatic transmission and wet brake fluids
Inventor: PAPAY ANDREW GEORGE
IPC: C10N70/00
Filed: 1992-05-21
Abstract: An increase in the dynamic and/or static coefficients of friction of frictional surfaces is obtained by the use of oil-based functional fluid compositions, eg. formulated for use as automatic transmission fluid or fluid for a wet brake system including a minor amount of at least one alcohol or polyol having less than 12 carbon atoms in the molecule. Preferred for this use is a composition formed by heating at least one ashless dispersant containing basic nitrogen and/or at least one hydroxyl group with a combination of at least (i) an inorganic acid of phosphorus, (ii) a boron compound, and (iii) a polyol having less than 12 carbon atoms, so that a liquid composition is formed. The boron compound and the inorganic phosphorus acid are preferably co-present during the heating. However, either such substance can be added and subjected to the heating step after the other provided that the conditions used result in the formation of a clear, liquid composition. The alcohol or polyol is preferably a 1,2- alkanediol, an aminoalcohol or aminoglycol.

Patent GB-2269248-A (GB)
Title: Digital audio synchroniser
Inventor: TRAVIS CHRISTOPHER JULIAN
IPC: H03H17/04
Filed: 1992-07-29
Abstract: A digital audio synchroniser includes one or a pair of FIFO buffer stores 12, 16 in series with a digital interpolating filter 14. A control circuit 18 detects when there is a "slip" between input and output, requiring loss or addition of a sample, and the filter executes a delay adjustment cycle in response thereto. The filter 14 takes the form of a substantially all-pass infinite-impulse-response filter of recursive form using feedback (Figure 4, 5, 6 or 7) which is found to give subjectively good performance although it introduces a frequency-dependent group delay, is also easy to implement, and has low overall delay.

Title: Improvements in or relating to surface ionisation ion sources
Inventor: FREEMAN JAMES HARRY
IPC: H01J49/16
Filed: 1993-06-12
Abstract: A surface ionisation source has a higher ionising efficiency than a conventional triple filament source such as is commonly used in mass spectrometry. The source incorporates a single heated filament 1 to evaporate the material to be ionised and an independently heated coil 2 which acts as the ionising element. The filament is positioned close to one end of the coil so that a major fraction of the evaporated material enters the coil and has a high probability of coming into repeated contact with the internal ionising surface before escaping from the open end. The voltage gradient between the two ends of the coil which arises from its resistance to the direct current used to heat it helps to steer and accelerate any ions which are produced towards the open end where they can then be further accelerated by electrode 3 and extracted as an ion beam. In modifications, the coil may be conical, and an external magnetic field may be provided to cancel or augment that of the coil itself. Apart from mass spectrometry, other uses include ion beam machining and implantation, and ion probes. <IMAGE>

Title: A swinging-sliding door
Inventor: FINK MARTIN
IPC: E05F15/603
Filed: 1993-10-22
Abstract: The invention relates to a swinging-sliding door with at least one door leaf suspended by means of a sliding carriage 3 on a rail so that it is axially displaceable and can swing about the rail, and which is guided by door guides (5, 6, 7, 8 Fig. 2). In order to eliminate the risk of entrapment, the invention provides for the operating mechanism to be electrically actuated and to act on a spindle 12 which operates the door via a nut 21. The end of the spindle remote from the operating mechanism is attached to a seating 22 via a free-wheel 23 which allows the spindle to turn in the direction which corresponds to the closure movement of the door, even when the seating is locked. The latter is mounted to be alternatively rotationally fixed or rotatable by means of a clutch comprising clutch disc 25, clutch linings 26 and counter discs 27, 28. The clutch is released automatically upon door opening or, in an emergency, by manual override. <IMAGE>
