Patent GB-2135131-A (GB)
Title: Improvements in or relating to monopulse detection systems
Inventor: HALFORD GORDON JOHN
IPC: G01S13/44
Filed: 1983-05-11
Abstract: A planar array (13) of radar antenna elements (B) used in a monopulse detection systems includes means to apply an appropriate phase by the phase delay (4) on transmission and reception so as to define only two beams. Received signals are added to give a sum beam (22), and for a normal beam perpendicular to the plane of the array appropriately weighted, signals are added in phase in a resistor network F1. A signal difference beam (27) is generated by added receiver outputs in a second resistor network F4 with each output phase delay (23) by a phase angle equal to the angular position of the detector measured from the array centre with respect to the array centre line (14). Then a target position can be defined by taking the ratio of the amplitudes and the relative phases of signals received by the sum and difference beams. Beam steering is done by applying additional phase delays to both beams to tilt the phase planes of the array as desired. <IMAGE>

Title: Reduced data rate signal separation system
Inventor: LEWIS HENRY GARTON
IPC: H04N9/78
Filed: 1984-02-03
Abstract: A system to separate components interleaved in frequency in the video input signal of a TV receiver, e.g. luminance and chrominance, samples the analogue signal at e.g. 4 fsc (i.e. 4xcolour subcarrier frequency). The signal is digitized (e.g. 8 bits) (10) and applied via a digital bandpass filter (12) and sub-sampler to a digital comb filter (20) working at a lower sampling rate (e.g. 2 fsc) to economise in storage locations. The comb filter output provides one component (chrominance) at a reduced sampling rate (2 fsc) and a second (luminance) at 4fsc may be obtained by interpolating (16) the first back to the original sampling rate (4fsc) and subtracting (18) from the original digitized signal. <IMAGE>

Title: Nuclear magnetic logging
Inventor: CLOW HUGH
IPC: G01R33/44
Filed: 1984-05-23
Abstract: An elongated probe suitable for lowering down a borehole for nuclear magnetic logging has a pair of similar cylindrical magnets 1 and 2 separated by a gap in which a solenoid 3 is symmetrically disposed. The solenoid has a core 4 of high permeability ferrimagnetic material and has a length preferably equal to half the length of the gap. The magnets 1 and 2 and solenoid 3 with its core 4 are contained within a hollow cylindrical casing 5 of non-magnetic material. The static & RF(coil) magnetic field distributions are such that after suitable filtering upwards of 95% of the NMR signal arises from points more than 10cm from the probe axis & is hence properly representative of the earth formation. Provision of the core also increases the Q of the coil & the signal to raise ratio of the signal. <IMAGE>

Title: Improvements in and relating to breathing apparatus
Inventor: CONSTANCE-HUGHES TREVOR
IPC: A62B18/10
Filed: 1985-04-15
Abstract: A self-rescue breathing apparatus having a combined cylinder-head and first-stage pressure-reducing valve 2 and a demand valve 5. The pressure- reducing valve 2 has a piston 31 and valve member 24 opposed to one another so that the inlet port 22 is within the valve cylinder 21 and only a single pressure seal 32, round the piston head 31 is needed. The cylinder head valve 2 also has means 14 to 20 for recharging the gas cylinder 1 without removing the gas cylinder from the apparatus or the valve 2 from the gas cylinder. The demand valve 5 is a negative-pressure diaphragm valve with a combined spring and valve lever 63 holding the valve shut against the supply pressure and a second lever 73 engaging the diaphragm 60 and lifting the first lever 63. The two-lever mechanism gives a compact and easily- adjusted valve mechanism. The apparatus also has a CO2 removing oxygen purifier (4, Fig. 3, not shown) and a breathing bag (10, Fig. 5, not shown) folded, rolled up and stored in an end cap (9, Fig. 1, not shown) when not in use. <IMAGE>

Title: A self-pumping hydropneumatic suspension strut with internal height control
Inventor: KUCHHEUSER WERNER
IPC: F16F9/50
Filed: 1985-05-14
Abstract: In a self-pumping hydropneumatic spring suspension strut with internal height control the pump rod is manufactured from two components 19a and 19b which are keyed together by a mechanical interengagement 26, 28, and a throttle 27 is disposed inside the pump rod in the region where the two parts 19a and 19b are joined together. Oscillations of the strut about a contracted position in which levelling port 25 is covered by the piston 2 cause liquid to be pumped from low pressure chamber 10 through the bore in the pump rod and suction valve 22 into the pump chamber 21 and then through exhaust valve 23 and passage 24 into the working chamber 16 which is in communication with the high pressure chamber 11,9. The throttle 27, formed as a notch in a valve seating engaged by a valve disc 31, does not influence the pumping up operation. When the strut extends sufficiently to cause the piston 2 to uncover the levelling port 25 in the pump rod, pumping stops and the working chamber is placed in communication with the low pressure chamber 10 via the port 25, the throttle 27 and the bore in the pump rod. <IMAGE>

Title: An improved optical fibre cutting tool
Inventor: ANDREWS PATRICK VASSAR
IPC: C03B37/16
Filed: 1985-06-13
Abstract: A hand tool for providing an optical fibre with an end face which is flat and lies in a plane radial to the fibre axis comprises four elongate members (1,2,3,4) extending side by side. The first member (1) is of tubular form and surrounds the other three members (2,3,4) and has, mounted near one of its ends, jaws of two pairs of jaws (16,17) transversely spaced on opposite sides of the longitudinal axis of the member (1) and, between the jaws (16,17), a table having a curved surface. The second member (2) is pivotally connected to the first member (1) at its end remote from the table (6) about an axis extending transversely of the members, is urged away from an internal surface of the first member (1) by a leaf spring and carries, near its other end, the other jaws of the transversely spaced pairs of jaws. The jaws of one pair of jaws (16,17) are so resiliently mounted on the first (1) and second (2) members that, when the jaws (16,17) move towards one another to grip an optical fibre between them, the parts of the jaws (16,17) in contact with the fibre will tend to move away from the table (6) and from the other pair of jaws (16,17) to exert a tensile force on the fibre. The third member (3) is pivotally connected to the first member (1) at its end remote from the table about an axis extending transversely of the members, is urged away from the first member by the leaf spring and carries near its other end an elongate cutter. The fourth member (4) is pivotally connected at one of its ends to the first member (1) and is so shaped intermediate of its ends that, when it is caused to pivot towards the third (3) and second (2) members an intermediate part bears against the third member (3) to cause the third (3) and second (2) members to pivot against the action of the leaf spring and so cause the jaws of the pairs of jaws (16,17) to grip an optical fibre positioned between them and to cause the cutting edge of the cutter to contact and move transversely across the tensioned optical fibre to score the fibre to such an extent that the fibre breaks to form end faces of the fibre that are flat and lie in planes radial to the axis of the fibre.
