Title: Change-speed airscrew gearing with pressure oil control
IPC: B64D27/00
Filed: 1939-02-23
Abstract: 525,615. Change-speed and reversing gearing ; positive clutches. FAIRBROTHER. H. (Bayerische Motoren Werke Akt.-Ges.). Feb. 23, 1939, No. 6078. [Class 80 (ii)] Planetary or countershaft two-speed airscrewdriving gearing, readily convertible to clockwise or anti-clockwise rotation, is controlled by hydraulically actuated repelling-tooth (i.e. chamfered tooth) dog-clutches 16, 27. synchronized by hydraulically-actuated multi-disc friction clutches 10, 24. Pressure-oil is supplied selectively through passages 6, 7 to either side of a piston 2, integral with the engine crankshaft 1, and engages one or other of the synchronizing clutches 10 or 24 by imparting an appropriate axial movement to a surrounding cylinder 3, connected for rotation with the crankshaft 1 by dogs 8, 9. At the same time, the pressure oil, through passages 12, reaches a chamber 13 or 23 on one or other side of a piston 3a formed on the cylinder 3, and thereby imparts a like axial movement to a second cylinder 14, splined on the first cylinder 3 and carrying the chamfered dogs 16, 27, which are thereby brought first into the repelling portion and, when synchronization is complete, into full engagement. The planetary arrangement, shown in Fig. 1, provides for clutching the crankshaft 1 selectively to either of two loose sun-wheels 11, 25 engaging a stepped planet-wheel 17 on a carrier 22 fast to the shaft 21 of the airscrew. If, as shown, the airscrew is required to rotate in the same direction as the crankshaft 1, reaction is taken by an internally-toothed fixed annulus 19. If reversed rotation is required, the annulus 19 is replaced by a fixed externally-toothed wheel engaging an additional smaller step on the planet-wheel 17. In the countershaft arrangement shown in Fig. 3, six stationary countershafts 32 are grouped about the crankshaft 31 and are each driven therefrom through a wheel 33. Each countershaft carries a double clutch 34 similar to that in Fig. 1, whereby a drive is imparted selectively to either of two wheels 35, 36, gearing with wheels 37 on the airscrew shaft 38. The wheels 37 are internally or externally toothed according to the direction of rotation required.

Abstract: 1,055,692. Photo-electric movement detection. EIDGENOESSICHES MILITAER DEPARTMENT. Feb. 13, 1964 [Feb. 20, 1963], No.6169/64. Heading G1A. In order to detect whether a body is moving or at rest a grid 1 is arranged for movement with the body and during movement intermittently interrupts the light beam from a source to a detector unit 2. The electrical output of the detector unit during movement is an A. C. signal fed through an amplifier to charge a capacitor 4. As long as movement persists the capacitor is charged and a relay controlled by the potential across it held closed. With the body at rest no charging signals are fed to the capacitor which discharges through a resistor and the relay is thus released.

Abstract: 793,035. Gas producers. GAS COUNCIL, and DENT, F. J. April 22, 1954 [March 6, 1953], No. 6338/53. Class 55 (1). A gas-producer has a generator 1 through which air and steam are passed alternately in " blow " and " run " periods, a regenerator 2 and a recuperator 5 both traversed by the blow gases during a " blow " period, air for the blow being preheated by passing through the recuperator and the whole of the steam for the run being preheated in the regenerator. During the blow period air enters by conduit 7, passes through the recuperator 5 in indirect heat exchange with the blow gases, and conduit 10 into the generator 1. Blow gases leave by conduit 3 and pass downwardly through the regenerator 2 and upwardly through the recuperator 5, secondary air being added to the gases at the top of the regenerator through the conduit 13a or partly at the top and partly at the bottom through the conduit 13b. During the run period, valve 4 is shut and valves 12 and 18 in the conduits 11 and 17 are opened. Steam is passed into regenerator 2 through valve 16 and pipe 15 and passes into the generator 1 through conduit 17, water-gas being withdrawn through conduit 11. Sensible heat in the water-gas and in the " blow gases after leaving the recuperator 5 may be utilized in a water-heat boiler. A carburetter and superheater may be provided for carburetting the water-gas if desired. In a modification the blow gases may be passed through the recuperator and then the regenerator or the blow gases may be divided into two streams and passed through the regenerator and recuperator in parallel.

Abstract: 779,462. Electron lenses. PHILIPS ELECTRICAL INDUSTRIES, Ltd. March 8, 1955 [March 11, 1954], No. 6789/55. Class 39(1). Astigmatism due to mechanical errors in symmetry of an electrostatic or magnetic electron lens are corrected by the electric and/or magnetic field produced by two or more tubular inserts surrounding the axis of the lens, the inserts having an axial length which varies around the circumference in such a way that the insert has two mutually perpendicular planes of symmetry. In a magnetic form, the main lens is constituted by pole-pieces 1, 2, Fig. 1, and this is followed by tubular inserts 13, 12 each provided with a waved, serrated or notched top edge the bottom one 12 being rotated 90 degrees relative to the other. By passing suitable currents through windings 14, 15 a correcting astigmatism at any desired angle may be introduced. In an electrostatic form, the main lens comprises earthed outer diaphragms 22, 23, Fig. 2, and high-potential inner diaphragm 26. Correction is by wavy-edged cylinders 29, 30, 31, the two outer ones being connected. The pairs 29, 30 and 30, 31 produce astigmatisms at right angles and these are combined in any desired ratio by adjusting the voltages. By combining electrostatic and magnetic fields, two tubular inserts 38, 39, Fig. 3, may be made to produce two astigmatisms with a single gap, since that due to the electrostatic potential difference is in fact at right angles to that produced by the magnetic field from coils 40 with the same shape of gap edges.
