Abstract: 1,009,730. Electric retroactive control. ENGLISH ELECTRIC CO. Ltd. July 23,1954 [July 28, 1953], No. 20963/53. Heading G3R. [Also in Division H4] The signals received from a target by a radar antenna are employed to effect automatic alignment of the antenna on the target. The error signal corresponding to the misalignment of the target and antenna cams alignment of the axis of a gyroscope, universally mounted on the antenna system, with the target direction. The error signal corresponding to the misalignment of the gyroscope and the antenna system causes movement of the antenna into alignment with the gyroscope axis and hence into line with the target. As shown, the target signal received at the antenna 43 cause energization of electromagnets 28, 29, 30, 31, of torque motor 21, which exert a torque on the coil former 26 mounted on the gyroscope 16, universally supported on the antenna dish. The gyroscope is moved until the spin axis is aligned with the target axis 40. The angular displacement between the axis of 16 and the dish axis is detected at 23 and the resulting signal applied to motors 14, 15, which move the dish until the two axes are aligned. In a further embodiment, not shown, the antenna dish is supported in a gimal system of the type described in Specification 735,359. Specifications 694,867, 735,359 and 928,410 also are referred to.

Title: Improvements in the lubrication of motor vehicles and fluid pressure engines
IPC: B60R17/00
Filed: 1926-08-27
Abstract: 266,614. Rowell, H. S. Aug. 27, 1926. Starting; turning-gear.-A device for supplying lubricant is so arranged in relation to some part of a fluid-pressure engine which must be operated in order to start the engine that the said part cannot, be operated until the device has supplied a charge of lubricant to the engine or to the vehicle on which 'it is mounted. As applied to an internal-combustion engine, the plunger 6, Fig. 2, of an auxiliary lubricant pump 2 is adapted to be operated by a hand lever 3, and a rod 12, connected to the lever, is adapted to operate the ignition switch 8 just before the plunger 6 has completed its stroke. The rod 12 may be carried by the plunger 6. The stem 13 of the switch may be arranged to project from the switch casing 7 after operation, so that it may be pushed in to switch off the ignition, or a loose button 14 having a pin-and-slot connection 15 with the casing 7 may be used for this purpose. A stirrup 17 may be carried on the rod 12 and have a stem 18 adapted to operate the switch 16 of an electric starter subsequently to the operation of the switch 8. In the arrangement shown in Fig. 3, engagement of a starting handle 21 with the engine shaft is prevented by a collar 23 engaged by a lever 25 connected by a rod 27 to an arm 28 through which the rod 29 of a lubricant pump 2 passes, the arm 28 being acted on by a spring 30. When, however, the pump 2 is discharged, a collar 31 engages the arm 28, thus freeing the handle 21. Alternatively, the pump may be actuated by the engaging movement of the handle 21. In an engine having an electric starter 32, Fig. 4, having a driving pinion 33 which, by the action of the starter, is moved axially into engagement with a gear wheel on the engine, this axial movement is used to operate a lever 34 actuating the pump 2. In another arrangement, the operation of the pump may serve to uncover a normally-concealed part, which must be operated to start the engine, or it may serve to release a locking device which normally prevents movement of a switch. In an engine having a foot-operated plunger actuating an electric or other starter, this plunger may be modified to constitute the ram of an auxiliary lubricant pump.
