Title: Recording and reconstructing digital data
Inventor: ARUGA MASAHIRO
IPC: G11B20/10
Filed: 1984-03-05
Abstract: A digital encoded signal (T) is filtered by a filter (11 Fig. 2a) to generate a series of pulses (V) from edges of said encoded signal. The pulses are recorded on a magnetic record carrier. The reproduced signal (W) has relatively low zero level shift making possible its reconstruction by a simple Schmitt trigger (14 Fig. 2a).   <IMAGE>

Title: Ultrasonic cleansing
Inventor: D ARCY DESMOND JOSEPH
IPC: B08B3/12
Filed: 1984-10-04
Abstract: A method of cleaning a surface of an underwater structure, in which focussed beams of acoustic energy are directed at a surface to be cleaned with an energy level sufficient to cause cavitation of the water adjacent the surface and/or direct mechanical disruption at the surface, thereby dislodging matter to be removed. In one embodiment a part-spherical array (1) of acoustic transducers (2) is arranged to direct the beams to a common focus (4). In an alternative embodiment, separate focussing means may be used with a flat array. An array may be hand held or mounted to an underwater vehicle. Part-cylindrical or parabolic arrays may also be used. The method is useful for cleaning subsea structures, e.g. oil rigs, at below 15 metres depth. <IMAGE>

Title: Metal vapour deposition drum construction
Inventor: HODDINOTT DR DUDLEY STUART
IPC: C23C14/50
Filed: 1984-10-05
Abstract: A rotary drum 30 used for the production of a layer 60 of a metallic material by deposition from the vapour phase onto an exposed surface 43 thereof, comprises a hollow cylindrical outer member 42, a coaxial hub 44, and a plurality of spokes 46 pivotally connected to the outer member 42 and to the hub 44, all the spokes 46 being aligned at the same oblique angle to the radius at the respective connections to the hub 44. Thermal expansion of the outer member 42 relative to the spokes 46 is accommodated by rotation of the outer member 42 relative to the hub 44 and a consequent change in the oblique angle, so minimizing thermally induced stresses in the spokes 46. The exposed surface 43 may be maintained at a desired temperature by passing a heat transfer liquid through ducts 94 within the rotary drum 30 and controlling the temperature of the liquid in accordance with the thickness of the deposited layer 60. <IMAGE>

Patent GB-2153014-A (GB)
Title: Automatically shuttered ventilator
Inventor: YOO BYUNG EUN
IPC: F24F7/013
Filed: 1984-11-30
Abstract: An air ventilator for ventilating indoor air to the environment is constructed so that when the motor 3 is operating, the centrifugal weight members 15 cause the rotatable circular plate (6), to displace angularly, the displacement being transmitted to the fan blades (10) for ventilating the inside air to the environment.

Title: Indirect ophthalmoscope
Inventor: BURROWS CLIVE HAROLD THOMAS
IPC: A61B3/135
Filed: 1986-09-29
Abstract: An indirect ophthalmoscope has an illuminating reflector, and means for adjusting the position and/or angle of incidence of the illuminating light beam (4) on the reflector. The adjusting means may operate to move laterally the lamp (7), or any illuminating stop (10), relative to the light path. Preferably, the adjustment operates to change simultaneously the position and size of the stop aperture. Additionally, the reflector may be pivotable about an axis parallel to its plane and perpendicular to the light path, for fine adjustment. These adjustments enable the operator to move the illuminating light beam incident on the eye of a patient, towards and away from the viewing optical path, providing a range of angles of divergence and a range of lateral separations between the illuminating a and viewing paths. <IMAGE>

Title: Transmitting digitally assisted television data signals
Inventor: PULLEN R IAN RICHARD
IPC: H04N7/015
Filed: 1987-12-08
Abstract: A method of transmitting a digitally assisted television (DATV) signal is described in which a received DATV signal is compatible with non-DATV receivers. The number of pulses in the field synchronising sequence may be reduced in conjunction with a reduction in the lengths of the line synchronising pulses, thus providing a free data channel. A DATV data signal is combined with the video waveform such that the DATV data signal occupies at least part of the free data channel. The resultant combined signal is then transmitted. Alternatively the free data channel can be provided by reducing the lengths of the colour bursts. This reduction in length of the colour bursts may necessitate an increase in their amplitude so as to maintain compatibility with non-DATV receivers.

Filed: 1989-07-04
Abstract: A fin-stabilised projectile (1) forming a weapon for attacking a tank (2) from above wherein at the final phase of the flight to the target a force acting on the tip of the projectile causes descent. Due to a rotation of a control unit (4) which carries a target-detecting sensor a gyroscopic precession causes the projectile to oscillate and to be deflected from the required path. To overcome the yawing angle and lateral deviation caused means are provided in the projectile between control unit (4) and warhead body (3) for imparting to the body (3) a rotary impulse equal to that of the control unit (4) but in the opposite direction. The means is so constructed to be suitable also as driving means for the rotation of the control unit (4). The opposite rotation of the two parts of the projectile may be effected by combined jet-nozzles (7) and turbine means (9) (Fig. 3) or, by oppositely directed nozzles (10) and (11), Figs 5 and 6, on the respective parts, or, by a spiral spring (12), Fig. 8, mounted between the oppositely rotating parts, or, by screw-threaded means 5.9 Fig. 9. <IMAGE>
