Title: Improvements in jettisoning petrol from aircraft
IPC: B64D37/26
Filed: 1940-01-04
Abstract: 535,841. Jettisoning petrol from aircraft. HALL, F. H. Jan. 4, 1940, No. 215. [Class 21] [Also in Groups XXVIII and XXXIII] Petrol is jettisoned from an aircraft, e.g. during a bad climb due to overloading by opening a valve 6 by the combustion gases of a cartridge exploded in a chamber 13, a delivery tube 36 being meanwhile released from its storage position by withdrawing the catch 39 of a trap-door 38 by a piston 41 actuated by the combustion gases. An air valve 26 consisting of two perforated cylinders separated by a cork disc and rotatable to bring the apertures into register is also actuated by the combustion gases through a spring-controlled piston similar to piston 41. After the tank is empty the combustion gases may be released through a valve and a valve 45 may be closed so that the tank may act as a float. As in Specification 488,105, a reserve supply petrol tank may be interposed in the main delivery pipe leading to the carburetter. The tube 36 may be a swinging tube and may be telescopic. Other types of valve may be employed. The trigger mechanism and cartridge chamber are shown at 20, 15, Fig. 3, and a fine metal gauze flame filter at 25. This cartridge chamber may be as in Specification 433,198, [Group XXXI].

Abstract: 287,701. Carter, B. C. Jan. 3, 1925. Radial-flow type; working-fluid supply.-Air introduced at ports 10, passes between radia blades 7 and is driven by centrifugal action through passages 12, 13 between radial blades 8 Fuel is introduced into passages 13 from pipes 14, the passages 12 being closed in the neighbourhood of the pipes 14 by bridge pieces 17. The mixture is ignited by plugs 15, not electrodes or catalytic devices, and the products of combustion mix with the air from the passages 12 and pass out of the rotor through rearwardly directed nozzles 9. The blades 7, 8 and the balls of the nozzles 9 overlap radially. The nozzles 9 may open on the sides of the rotor. Screw blades 19 may be fitted in the air ports 10. The air may be supplied under pressure to the ports by a pair of centrifugal compressors. The flow through the rotor may be made intermittent by means of a cylindrical stationary grating. The rotor may be used without any casing, or the casing may be arranged as a second rotor with exhaust nozzles. When compressors are used, air may be used to cool the casing. Specification 227,151 is referred to.
Patent GB-1452032-A (GB)
Title: Locks
IPC: E05B47/06
Filed: 1974-01-04
Abstract: 1452032 Locks GOAL CO Ltd 4 Jan 1974 00396/74 Heading E2A A lock comprises a cylinder lock 17, a lock case 11 to which a knob for use inside a door is mounted so as to be capable of being turned and a knob 13 for use outside the door is rigidly fixed and wherein a latch bolt 16 is released either by turning the inside knob or by operating the cylinder lock 17 incorporated in the outside knob and a solenoid 20 which controls the movement of a locking member 25 for the purpose of preventing the latch bolt from being released by the operation of the cylinder lock. The cylinder lock 17 is connected by a rod 18 to an actuator 19 with a terminal hook for actuating the bolt 16. The internal handle 12 is connected to a spindle 14 with a terminal hook for actuating the bolt. The locking member 25 projects from one end of a plunger 23 and is urged by a spring 24 to engage in a slot 19' of the actuator 19 and is prevented from turning by engaging in a groove 26' of the lock case. The locking member thereby obstructs turning of the actuator to release the bolt 16, when the solenoid 20 is actuated plunger 23 is withdrawn to withdraw the locking member 25 from the slot 19' to allow rotation of the actuator 19 and withdrawal of the bolt when the lock 17 is actuated. The locking member may be retained in locking and unlocking positions intermittently by a device 30 actuated by the current flowing intermittently. The device comprises a rotor 33 rotatably connected to one end of the plunger 23 and rotatable within two interconnected rings 31, 32. The ring 31 has internal protrusions 31A, and the ring 32 has a deep slot 32A and a shallow slot 32B. The rotor has a tooth 34 which engages slot 32A when the locking member is operative when the solenoid is actuated the tooth strikes a tapered surface 31 and causing the rotator to turn through the pitch of one tooth and engage slot 32B when the current is switched off, thus holding the locking member in the inoperative position. When the solenoid is again actuated the operation is repeated and the pin 34 engages the next deep slot 32A. Thus locking is effected intermittently to prevent the coil being burnt out. Locking may also be effected intermittently by using a solenoid with a ferromagnetic core 22 which is alternately magnetised and demagnetised by changing the direction of current which flows in the exiting coil 21. The solenoids of a number of locks may be controlled from a caretakers' room though any room can be left by operating the inside handle. The solenoids may be in circuit with two micro switches operated by the locking members and by opening and closing the doors respectively connected to a lamps L and a buzzers B this permits continuous surveillance of a number of locks. The solenoid may be actuated by a card reader which is used on another door such as a porch door, whereby the lock may be actuated only by a person who has a key and a card reader.

Title: Device for scanning a record carrier and control circuit for use in such a device
Inventor: BIERHOFF MARTINUS PETRUS MARIA
IPC: G11B7/09
Filed: 1996-03-14
Abstract: A device is disclosed for scanning a record carrier (1) provided with substantially parallel tracks, which device comprises a closed-loop position control system with position and velocity feedback for controlling the scanning point (P) towards the centre of a specific track. For this purpose the position control system comprises a positioning system (15) for moving the scanning point in a direction transverse to the tracks, a measuring system (4, 6, 9, 10, 11, 12, 13) for generating a velocity signal (RS) which is indicative of the velocity with which the scanning point (P) is moved across the tracks, and for generating a first error signal (RE) whose magnitude, within a predetermined limited range to either side of said specific track, is proportional to the deviation between track centre and the scanning point (P). The position control system further comprises a control circuit (3) for controlling the positioning system depending on the first error signal (RE) and the velocity signal (RS). The control circuit (3) comprises means for generating at least one substitute error signal (PE min , UC min ) which within a second range, outside the first range, has a sign which is indicative of the direction of the deviation, the control circuit (3) being adapted to control the positioning system (15) in response to the first error signal (RE) or a substitute error signal (UC min , PE min ) depending on whether the deviation is situated in the first range or the second range respectively, in such a way that the error signal employed for position feedback depends on the magnitude of the deviation, and the velocity signal (RS) used for velocity feedback is independent of the magnitude of the deviation.
