Patent GB-2152687-A (GB)
Title: Video camera shutter
Inventor: SWINEHART STEVE LOUIS
IPC: H04N5/225
Filed: 1984-10-30
Abstract: A focal plane shutter for a video camera has a pair of discs rotated in the same direction about a common axis in synchronism with the raster scan blanking interval, at a nominal rotational rate of 3600 rpm. The discs each have a single opening which overlie one another to define a single light admitting shutter aperture positioned to illuminate the video pickup once per revolution. Stop action or slow motion studies are greatly improved by the increase in shutter speed resulting from this single aperture shutter. The relative angular positions of the discs can be varied while the discs are rotating in use, eg by mechanical linkages or a hydraulic system. Preferably each opening is bounded on first and second sides by lines emanating from a point on the disc which is offset from the disc's axis of rotation preferably by a distance equal to the length of the diagonal of the raster. This enables an even exposure of the video pickup, of equal areas at equal times no matter where the pickup is positioned relative to the disc's axis of rotation. <IMAGE>

Title: Electromagnetic chain gun
Inventor: ADAMS THOMAS PHILIP
IPC: F41B6/00
Filed: 1988-02-15
Abstract: An electromagnetic gun comprising parallel conducting electrodes is used to fire a continuous rubber chain. On firing, links leaving the barrel will have higher velocity than those already ejected and so the chain will tend to become coiled in flight covering a volume in flight which relaxes the firing accuracy requirement for hitting incoming projectiles aimed at ships for example. The chain 40 comprises a series of links 20 with conducting armatures 21 provided at intervals less than the length of the gun barrel 45 for current conduction. A magazine arrangement 41-44 may be provided which feeds the chain to the barrel so as to lessen the impedance to acceleration of the chain on firing. Flying cutters 46 may be provided to cut predetermined lengths of chain for firing. <IMAGE>

Title: Pressure monitoring shut-in tool
Inventor: ZWART KLAAS
IPC: E21B47/06
Filed: 1988-06-03
Abstract: The pressure monitoring shut-in tool 11 has an elongate body 12 closed at the lower end and adapted at its other end for attachment to a locking device for locating into a wire line landing nipple 16 and having in its wall primary communication ports 13 and secondary pressure monitoring ports 14 and a sleeve 15 is slidably moveable within the body between a lower 'open' position in which fluid can flow through the primary ports 13 and an upper 'closed' position in which such flow is blocked. The sleeve provides a flow passage in communication with the pressure monitoring ports 14, and is biased to the lower 'open' position. The sleeve 15 has a latch mechanism for attachment and detachment of a stinger 10 which is connected to pressure sensing means and which lifts the sleeve 15 by a working pull into the closed position. The latch mechanism is biased against the upward working pull. Due to differential pressure acting on the sleeve when it is in the closed position, the sleeve will remain in the closed position during the shut in measuring procedure and even after release of the stinger. However, with the fluid flowing again through the pressure monitoring ports 14 and sleeve 15, pressure will proceed to equalize and the sleeve 15 will return to its lower open position under its bias when the well pressure is nearing a balanced position. <IMAGE>
