Title: Improvements in or relating to apparatus for aeroplane launching
IPC: B64F1/10
Filed: 1937-08-31
Abstract: 490,408. Launching aircraft. COURTNEY, F. T. Aug. 31, 1937, No. 23841. Convention date, Aug. 31, 1936. [Class 4] An aircraft launching-device includes a car for supporting the aircraft, means for accelerating the car up to the take-off speed of the aircraft and an aircraft support pivoted about a substantially vertical axis on the car. In one form, an aeroplane or seaplane 15 is mounted on a truck 13 which is hauled up a ramp onto a track or runway 11. The truck 13 may be provided with propelling means either mounted thereon or on a truck 18 adapted to be coupled to the truck 13. The truck 18 may be propelled by variable-pitch airscrews 20 driven from aero-engines 19 and controlled, e.g. by detachable electric connections by the pilot. The cradle 14 may be tilted about an axis 22 so that the aircraft is held nose-down until the instant of taking-off. The tilting may be effected by operation of the aircraft controls, or by toggle mechanism 23 operated by an electric motor 24 controlled from the pilot's cockpit or automatically by a bellows device 51 operated automatically by air flow through a Venturi tube 52. The aircraft may be locked to the cradle by means adapted to be released when the aircraft is tilted to the correct attitude for take-off. These means may comprise a toggle, actuated by tension in an anchored cord. The toggle may be tripped by electromagnetic means operated by the pilot and connected with a spring-actuated toggle connected to a hook engaging the step in a flying boat hull. The cradle is mounted on a turntable such that the aircraft may be turned into the direction of the relative wind either manually or automatically. Means may be provided for tilting the turntable laterally about a ball joint. Braking means 56 under control of the pilot may be provided on the truck 13.

Title: Improvements in or relating to oscillating drive mechanisms
Inventor: NIGHTINGALE ROBERT ALLEN
IPC: H01Q3/06
Filed: 1950-09-29
Abstract: 701,791. Aerials. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. Aug. 9, 1951 [Sept. 29, 1950], No. 23939/50. Class 40 (7). [Also in Group XXXVIII] A power driven mechanism for oscillating a radar aerial in a sector in azimuth is provided with means for varying the mean position of the sector in discrete steps, both movements being controlled by a single electric motor. As shown in Fig. 1, the mechanism comprises a fixed vertical spigot 7, a horizontal bevel gear 15 and a member 6 both rotatable about the spigot, and a housing 12 which is mounted in bearings in the main housing and is free to rotate about the vertical axis of the spigot. The housing 12 carries the aerial (not shown), the motor 1 and a vertical bevel gear 3 engaging gear 15 which is driven by the motor through a reduction gear 2; an eccentric pin 4 in the bevel gear 3 engages a vertical slot in the link 5 attached to the member 6. The member 6 is normally prevented from rotating by a magnetically controlled dog clutch 8, 9 so that rotation of gear 3 by motor 1 causes the housing 12 to oscillate but when the operating coil 16 of the clutch is energized, member 6 is released, gear 15 is locked and the housing 12 rotates continuously until coil 16 is de-energized. As shown in Fig. 2, the required mean position of the oscillation sector is selected by switches 18 and 24 connected in series with the clutch coil 16 and the power supply + -, switch 18 comprising seven contacts a ... g fixed to the spigot 7 and a brush 17 connected to the member 6, and switch 24 comprising corresponding contacts a ... g and a contact disc with a cut out segment so that when the segment is set opposite a particular contact, e.g. d as shown, coil 16 will be energized and the housing 12 and member 6 will rotate until the brush 17 reaches the corresponding contact d in switch 18 when the coil 16 will be de-energized and the rotation will cease. The contacts on switch 18 are not spaced uniformly since when the housing 12 rotates uniformly the rotation of member band the brush 17 is non-uniform. A toggle-type reversing switch 25 is mechanically interlocked with switch 24 to ensure that the mechanism will rotate in the correct direction determined by the direction of rotation of switch 24 and a reversing switch 21 actuated by the clutch ensures that if the mechanism over-runs the selected position it will oscillate between its extreme positions until the fault is cleared. A toothed cam and roller-lever type interlock 27 is mechanically linked with switch 24 and prevents operation of the switch either when the supply is interrupted or when the brush 17 is positioned between the extreme contacts a and g, the solenoid 26 being energized via slip rings 22 and brushes 23 ganged with switch 18.

Title: Measurement of the thickness of layers
IPC: B29C48/92
Filed: 1971-04-19
Abstract: 1352777 Measuring thickness of layers electrically B ZUMBACH [trading as ZUMBACH ELECTRONIC-AUTOMATIC] 19 April 1971 [11 March 1970] 24082/71 Heading G1N In a contactless measurement of the thickness of a layer on a body e. g. cables, insulated pipes or coatings on sheet material the distance of the measuring head from the layer is controlled by directing a jet of air from a sensing nozzle against the surface of the layer and mechanically controlling the position of the head by a servomotor controlled by the pressure in the sensing nozzle. Cable 2 passes from spraying head 1 between two sensing nozzles 16 around the lower one of which is wound inductive pick up coil 18 of a frequency modulated oscillator. Nozzles 16 are supported on axially movable supports 13 associated with fixtures 11 fixedly mounted on rotatable annular support 9 which is swingably rigidly mounted 4, 5 to frame 3 carrying the spraying head 1. After swinging the nozzles 16 into position as shown astride the cable the jets are moved independently to a predetermined distance from the surface of the cable and maintained there by the servomotor. Thickness of the insulating layer on the cable is determined from the output of the oscillator which varies in accordance with the thickness of the insulating layer. The outer diameter of the cable 2 is measured by means of an inductive differential transducer 24 mounted on the support 13 which measures the distance between the jets 16. After the measurements have been taken the sensing nozzles are disabled and the support 9 rotated by 90 degrees so that the nozzles 16 and coil 18 are horizontal, the measurements being then repeated. Between each set of measurements the device may be zeroed and by rotating the lower nozzle 16 about axis 21 to the position shown in dot-dash calibrated against the layer thickness of standard cable 22. Both nozzles may be mounted on a common carriage rotatable about axis 21. To maintain the measuring head symmetrical with the cable 2 two auxiliary nozzles may be symmetrically arranged with respect to the upper nozzle 16 and connected in a measuring bridge which acts on a servomotor to position the measuring head in the required position. Alternatively two auxiliary measuring coils may be used. In another arrangement Figs. 4 and 5, (not shown) the measuring coil may be wound on a core provided with an elongated air gap and a finely slotted nozzle, the cable being drawn thereacross. With this arrangement the position of the cable in the uniform magnetic field in the air gap is not critical and effects due to sagging of the cable are obviated. A measuring coil may be provided around the upper nozzle in which case the number of measurements required are reduced.
