Patent GB-2123249-A (GB)
Title: Scanning transmission electron microscopes
Inventor: SMITH KENNETH CHARLES ARTHUR
IPC: H01J37/22
Filed: 1983-07-07
Abstract: In a scanning transmission electron microscope 1 the image of the diffraction pattern formed on a phosphor screen 6 as a result of electron beam impingement on a point on the specimen 4 is converted by a camera 7 into a video signal and digitised in an ADC converter 9 and stored in a digital store 10. The stored signal is then modified by a weighting factor representing a notional pattern overlaying screen 6. The weighting factor may have one of two binary values, representing a notional opaque and transparent pattern, or may have a multiplicity of different values. The modified signals are then added together to provide a picture value for the point of impingement. By this means a complete picture is built up point-by-point. To speed up the picture taking operation diffraction images from different points may be displayed on different parts of screen 6 so that several images can be scanned together by camera 7. <IMAGE>

Title: Dibber drill
Inventor: BUFTON LESLEY PHILIP
IPC: A01C7/04
Filed: 1983-08-04
Abstract: A dibber drill 6 comprises a seed wheel 28 from which seeds 27 are taken by the negative pressure dibbers 10 of a contra-rotating placement wheel 8. When the dibbers 10 reach their lowermost (planting) position, an associated cam-operated plunger 14 presses the seed to a predetermined depth into the consolidated soil at the bottom of the hole formed by dibber 10. At the same time, a quantity of water is injected in the hole via a hollow section of plunger 14, this supply being maintained while the plunger is in contact with the soil thereby to prevent or free blockage of the plunger aperture by the soil. In an alternative embodiment (Fig. 3) the plunger of the above arrangement is replaced by a punch having at its end faces a seed-holding aperture. <IMAGE>

Title: Missile guidance system
Inventor: LAWRENCE RICHARD VINCENT
IPC: G05D1/12
Filed: 1984-02-07
Abstract: In a missile guidance system (20) a strap-down target sensor has an asymmetric field of view and yaw, pitch and roll autopilots 26-28 are responsive to yaw, pitch and roll rate demands 21-23 derived from acceleration demands 24, 25 in elevation and azimuth and sight elevation #: in order to keep the target within the restricted field of view the roll rate demand includes a prediction of roll rate, which is preferably derived from achieved pitch rate Wya and scaled inversely with respect to azimuth angle #. The sensor may provide a greater field of view in azimuth than in elevation and may be arranged asymmetrically in azimuth with respect to missile boresight. When a high predicted roll rate demand occurs the yaw motion may be set to zero or the inputs to the autopilots may be temporarily replaced by boresight controls.

Patent GB-2168226-A (GB)
Title: Distribution apparatus
Inventor: SEACOMBE RAYMOND JOHN
IPC: H04N7/173
Filed: 1985-10-29
Abstract: A hybrid cabled T.V. distribution system has features of switched star and "tree and branch" systems. Basic fare subscribers may receive simultaneously a basic group of channels fed at U.H.F. Premium subscribers can additionally control a switch at a star-point to select premium channels. The switches have superheat converters to convert channels supplied at V.H.F. to a predetermined U.H.C. channel, using a programmable local oscillator. The frequency plan has all V.H.F. frequencies and a pilot reference frequency supplied to the switch phase-locked to multiples of the nominal U.H.F. channel spacing. The local oscillator is phase-locked to the pilot so the U.H.F. signals are all synchronised and intermodulation products minimised. In an alternative arrangement, channels supplied at V.H.F. are simultaneously converted to a common I.F. on separate signal paths. A switch matrix controlled by the subscriber selects one of the I.F. signals which is then converted to a predetermined U.H.F. channel for supply to the subscriber.

Title: A method of power generation and it's use in a propulsion device
Inventor: KERSHAW HERBERT ARTHUR
IPC: F02B75/02
Filed: 1986-09-10
Abstract: The method uses a compressed primary fluid (eg gas) to heat and vaporize under pressure a liquid secondary fluid and the use of the resultant vapour/gas/steam or mixed said compressed primary medium and said vapor/gas steam for power generation purposes in for example an expansion device. Various methods of compressing the medium and various uses of the method (eg in gas turbine, i.c. oil, two stroke, four stroke engines) are contemplated. In a propulsion device application, ambient air compressed in cowling 6 transfers heat to a chamber 2 via fins 4 whereby liquid CO2 supplied by injector 1 at an atomiser 3, is vapourised and ejected through jet-pipe 7 via a nozzle 5, thus assisting, by induction, the air flow through the cowling 6. A pump 10 is used during starting, thereafter the injector 1 is stated to be driven by fluid bled through line 9. A three-way valve 8 enables transfer from a liquid CO2 supply to a liquid air supply at high altitudes. The fluids leaving the pipe 7 may be used to drive a turbine driving a fan or an airscrew. <IMAGE>
