Title: Co-axial cable stripping tool
Inventor: LIVERSIDGE BARRY PETER
IPC: H02G1/12
Filed: 1986-10-13
Abstract: A tool 10 for preparing the end portion of a coaxial cable has a blade 37 which may pivot between two limiting positions, in one of which the cutting edge 38 of the blade lies across a cable-receiving opening 22 to a greater extent than in the other of which positions. On inserting the co-axial cable through the opening 22 and rotating the tool 10 around the cable in one sense, the blade is caused to move to one limiting position so effecting one depth of cut, but on rotating the tool in the other sense around the cable, the blade is caused to move to the other limiting position so effecting a different depth of cut. In this way the different layers of the cable may be severed and removed. <IMAGE>

Patent GB-2184202-A (GB)
Title: Universal joints for a cardan shaft
Inventor: LINDENTHAL HANS
IPC: F16D3/38
Filed: 1986-12-04
Abstract: In order to increase the transmittable torque of universal joints on cardan shafts, tube-shaped joint halves (2, 3) of annular cross-section are used instead of the conventional yokes, the bearings (4) for the journal cross (6) being arranged near the end faces of the halves. The journals (7, 8) of the cross are not located in one plane but are arranged on the core piece (9) in two different planes which are axially spaced. Due to the kinematic inequality resulting from this, such joints should preferably be used only for applications where the joint operates mainly in straight position or at small angles of deflection and speeds. The advantages, however, are higher strength of form and torsional rigidity of the coupling halves which, unlike yoke-shaped halves, are not subjected to high shear and bending forces. For a given journal cross size, the joint can have smaller external dimensions making it a component of optimum strength throughout. <IMAGE>

Patent GB-2214651-A (GB)
Title: Colour Holograms
Inventor: ANDREASSEN JON
IPC: G03H1/26
Filed: 1988-01-21
Abstract: Colour holograms are manufactured by a method using red, green and blue (R, G, B) light for a true colour hologram. A reference beam (4) and an object beam (3) are formed for each colour from a respective source (S1, S2, S3) generating object and reference beams through optical fibres. For each colour in turn the object beam (3) illuminates the object (9) and then intersects with the respective reference beam (4) and is incident on areas of a holographic recording medium (12) which are predetermined by an apertured mask (10) for a predetermined exposure time. The mask (10) is moved between exposure so that no area of the recording medium (12) is exposed twice. Thus an array of mini holograms is produced (Fig. 1). To reconstruct a true colour image from the hologram (Fig. 3) it is illuminated with reconstruction beams which correspond to the reference beams, a stationary apertured mask being employed to ensure that light from any one reconstruction beam is only incident on those mini holograms recorded at that wavelength. By exposing successive frames (11) of holographic recording material a holographic motion picture film can be obtained. <IMAGE>

Patent GB-2268030-A (GB)
Title: Signal discrimination
Inventor: SEARLE JEFFREY GRAHAM
IPC: H01Q3/26
Filed: 1988-05-07
Abstract: An adaptive antenna array has means 10 for scanning the selectively combined outputs of the array. An adaptive filter 11, (Fig. 3) is arranged to discriminate predetermined criteria of the wanted signal (5 Fig. 1). When the adaptive filter output exceeds a level set in a threshold circuit 12 indicating a significant presence of the wanted signal S, a control circuit 13 halts the scan and sets selector switch 14 to select the array output at which the scan is halted. At intervals the control circuit repeats the scan and the selector switch is reset accordingly. Thus the array operates to discriminate in favour of the wanted signal (S) and against the jamming signals (I1, I2, I3). The selectively combined outputs fed to the means 10 have differing degrees of complexity. <IMAGE>

Title: Driver circuit
Inventor: CHOE MYUNG JUN
IPC: H03K19/08
Filed: 1990-10-15
Abstract: The present invention provides a driver circuit in which switching speed of transistors 06, 08 is improved and power consumption reduced by the prevention of oversaturation of switching transistors Q7, Q8 and by controlled current leakage. Controlled current leakage is obtained by the provisions of a switchable current path, preferably in the form of a MOS transistor N2, N3 and oversaturation prevention is preferably achieved by an arrangement involving level dropping diodes D1, D2 and an inverter including a pair of complementary MOS transistors P1, N1 interposed between input Vin and driver transistor Q7. The controllable current path N2, N3 prevents unnecessary current leakage during ON state of associated transistor Q6, Q8 and thus reduces power consumption. Charges stored at the base of the main switching transistors Q6, Q8 are discharged rapidly at turn-off via respective MOS transistors N2, N3 thereby improving the switching speed of the circuit. The switching ON or OFF of Q6, Q8 is controlled by Q7 and also by I1 and P2. <IMAGE>
