Title: Cancelling second trace clutter in pulse doppler radar
Inventor: HARTLEY PETER LAMBERT
IPC: G01S13/20
Filed: 1980-07-23
Abstract: A pulse doppler radar has p.r.f. jitter with successive pulse repetition intervals determined by a p.r.i.counter 28 in accordance with a predetermined pseudo-random sequence. At intervals less than the beam dwell time of the radar, the p.r.i. counter 28 produces an extra long p.r.i. During the extra long p.r.i., the received doppler radar signal values for range cells corresponding to record trace retums forthe normal p.r.i.'s are stored in a memory 25. The stored values for respective corresponding second trace range cells are read out during subsequent ordinary p.r.i.'s under the control of a range counter 40, and subtracted from the received signal values for the range cells, so as to cancel second trace clutter.

Title: System condition indicator for burner control system
IPC: F23N5/24
Filed: 1980-08-14
Abstract: A system condition indicator is for monitoring a number of interlock switches and fuel valves to detect what event first occurs to shut down a burner control system. The monitoring circuitry is periodically strobed once each cycle of a power line signal and is only responsive to an abnormal condition of an interlock switch or a fuel valve during the strobe time. The indicator does not respond to an abnormal condition for a predetermined time after burner operation is initiated, to allow the system parameters to go to their operational values. The indicator includes circuitry for monitoring the pilot fuel flow and the main fuel flow and for providing an indication if either flow is abnormally terminated to shut down the burner control system. When the burner control system is shut down in response to an abnormal condition, an indication is provided of the first interlock switch or fuel valve to open or close, allowing a determination to be made of what caused the burner failure, either during start-up or during normal operation.

Title: Erecting an off-shore drilling platform
IPC: E02B17/08
Filed: 1980-11-24
Abstract: A prefabricated. off-shore, well- drilling or other platform 4 having upstanding legs 50 for attachment to the superstructure of a support 2 is elevated by jacking units 190 attached to the platform. The support 2 comprises four buoyant caissons 8, 12 and is towed to the drilling site in a horizontal position. It is then tilted into an upright position by controlled flooding of the caissons. The platform is also buoyant and has four open caisson wells arranged in the same geometric pattern as the caissons of the support. The platform is towed to the drilling site and positioned in alignment with the support. At least one pair of preassembled jacking units 190 is mounted upon the platform at each caisson well. A superstructure 40 is premounted on the upper end of each caisson. A set of self-energizing "fail safe" slips is mounted in the superstructure near each of its ends. Means are provided for positioning each jacking leg 50 so as to positively lock its upper end in the slips in the superstructure after berthing. Each jacking unit also includes a jacking mechanism comprising two slip holders 214, each containing a set of self-energizing, "fail safe" slips 218 surrounding the jacking leg 50. Lifting rods 202 associated with slip holder housings 188, 190 are pivotally connected at their lower end to the platform. Each jacking unit also has a cylinder and piston 262 on opposite sides of the jacking leg. Elastomeric members 272 mounting the piston and cylinder assemblies in the slip holder housings yield to relieve stresses and provide uniform load distribution. The pistons and cylinders are operable to cause the slips to incrementally raise the platform on the suspended jacking legs and to hold it in its raised position. The slips also function automatically to hold the platform on the support in any position to which it is raised by wave action, thereby at all times preventing the platform from dropping back onto the water. <IMAGE>
Patent GB-2065316-A (GB)
Title: Electronic flash circuitry
IPC: G03B15/05
Filed: 1980-12-09
Abstract: Where two electronic flashtubes are to illuminate a scene to be photographed, and the total light reflected from the scene as well as the relationship between the light from each flashtube are to be controlled, it is difficult to monitor the light from each flashtube separately when they are fired simultaneously. To enable the light to be monitored, the flashtubes 12 and 15 are fired sequentially with a delay between the two firings. The delay can be obtained in a flash circuit where the flashtube outputs are quenched by using the quenching signal for the first flashtube as a firing signal for the second flashtube. Alternatively a fixed delay may be used. A typical application is where two flashtubes are used to provide direct and indirect illumination. As shown, operation of a camera synch switch energises bounced flashtube 12. The reflected light is detected by a photosensor 18 which after receipt of sufficient light quenches tube 12 and energises direct illumination tube 15. Sensor 18 continues to detect and, when the total illumination is sufficient, switches off tube 15. If tube 12 has not produced a given amount of light within 40 microns of energisation, (e.g. if used outdoors), it is quenched and tube 15 is energised. <IMAGE>
