Title: Fluid-borne vehicles
IPC: B64C27/12
Filed: 1972-12-19
Abstract: 1424006 Aircraft K EICKMANN 19 Dec 1972 58672/72 Headings B7G and B7W A fluid borne vehicle, particularly a helicopter, comprises two positive displacement fluid motors 6, 12, connected in series with fluid flow producing means 2 by conduits 4, 10, 14 and having shafts 7, 16 bearing rotating propulsive members such as rotors 8, 17, the motor 6 being nearer the leading end of the vehicle and having a volumetric displacement capacity 0À5 to 15% greater than that of the motor 12 so that fluid from the means 2 causes the motors to rotate at speeds dependent on the capacities of the motors. Thus the rear rotor will rotate faster and the vehicle will incline at an angle # to the horizontal, and the thrust of the rotors will have a horizontal component for translation. There may be a controlled conduit 24 by-passing the motor 12 to equalize the speeds of the rotors for purely vertical movement. There may be four fluid motors (40)-(43), Fig. 3 (not shown), the forward motors being of greater capacity than the rear, with diagonally opposite pairs connected in series. Specification 1,085,541 is referred to. Reference has been directed by the Comptroller to Specification 1,085,541.

Title: Earth borehole tool
IPC: E21B33/128
Filed: 1970-12-16
Abstract: 1,261,490. Boring earth &c. GENERAL OIL TOOLS Inc. 16 Dec., 1970 [12 Jan., 1970], No. 49674/70. Heading E1F. Borehole drilling apparatus comprises a mandrel 23 connected to a drill string 22, a packer 25 connected at one end to the mandrel and having the other end slidable along the mandrel from a drilling position in which the packer is disengaged from the borehole wall to a packing position in which the packer engages the wall, and means 61, 62 to latch the packer in the disengaged position. The other end of the packer is fixed to a retractor 60 having latches 61 mounted on spring fingers 67 and cooperating with grooves 62, 65 in the mandrel and a sleeve 27 respectively, the sleeve carrying the bit (not shown). The interior of the sleeve has bars 29 engaging mandrel grooves 30, 34 in the drilling and packing positions respectively. The apparatus is lowered into the borehole with the packer held disengaged from the wall by the latches engaging the groove 62, the sleeve being supported by its bars engaging between teeth 51 on the mandrel (as shown). When the bit reaches the hole bottom further lowering of the mandrel forces cams 54 to direct the blocks into the grooves 30 so that rotation and pressure on the string causes the bit to extend the borehole. The apparatus is set in the packing position by raising and lowering the mandrel so that the blocks enter the grooves 34 and the packer is compressed to engage the wall. As the mandrel is lowered to compress the packer a projection 64 on the sleeve transfers the latches from the groove 62 to the groove 65 to provide means to move the retractor when the sleeve and mandrel return to the drilling position. When the packer is engaged with the wall holes 85 in the sleeve communicate with holes 88 in the mandrel so that formation fluids may be sampled or the formation may be treated. The packer may set to act as a down-hole blowout preventer. A rotary stabilizer 78 is fitted on the top of the sleeve, a second stabilizer may be fitted above the packer, and drill collars may be fitted between the bit and the lower end of the sleeve. During fishing operations teeth 83 are engaged to prevent relative rotation between the top of the sleeve and the packer and teeth 82, 84 are engaged to prevent the stabilizer rotating on the sleeve.

Patent GB-2307808-A (GB)
Title: Surveillance apparatus
Inventor: GUPPY JOHN REGINALD
IPC: G01S3/781
Filed: 1979-04-27
Abstract: A surveillance apparatus comprises a main memory (1) in which is stored a separate value for each elemental area of the scene being surveyed. A detector scanning the scene provides azimuth and elevation co-ordinates for any elemental area from which radiation exceeding a given level is detected. Be co-ordinates are used to address the main memory (1), the contents of the addressed memory location being incremented or otherwise modified by applying them as an address to a first look-up table (6), which supplies a modified value for entry into the same location of the memory (1). In addition, a control logic unit (5) includes a memory scanner which scans each address in turn of the memory (1), uses the contents of each scanned memory location as an address for a further look-up table (7) and re-enters the value derived from the further look-up table in the scanned memory location. Thus, the contents of a location in the main memory may be incremented by a predetermined amount in response to detected radiation from the corresponding elemental area of the surveyed scene, and the contents of all memory locations, if non-zero, may be decremented in each scan by the look-up table (7). A display (8) provides data relating to the scanned area and derived from the memory (1) and may, for example, indicate fresh signals with a flashing light. A microprocessor (2) is used to load the look-up tables and to control the display.
