In an air intake duct for a gas turbine engine, the bottom of the air intake duct at the upstream end thereof extends or is extensible forwardly of the top thereof so that the plane of the inlet of the air intake duct is, or may be rendered, oblique to the engine axis, the air intake duct having a movable part which is movable into and out of an operative position in which the said plane is rendered oblique, or in which its obliquity is increased. In a first embodiment Fig.1, the air intake duct 12 has its inlet plane 15 disposed normal to the engine axis. A part-cylindrical axially slidable member 13 having an oblique forward edge 14 is associated with the lower part of the air intake duct 12. The retracted non- operative position of the member 13 is indicated in full lines so that the plane of the air intake is the normal plane 15. In the extended or operative position of the member 13 indicated in chaindotted lines, the effective plane of the air intake is the oblique plane indicated by broken line 16. In this operative position the intake is effective in reducing noise so far as a person situated below the engine is concerned. In a second embodiment Fig.2 2 (not shown), the air intake comprises a forward cylindrical portion 20 which is pivotally mounted at 21 to the main duct portion 22, the forward portion being swung forwardly to the position indicated in broken lines so that the plane of the inlet is then the oblique plane indicated at 16 when noise suppression is to be effective. In the normal position the plane of the inlet is the normal plane indicated at 15. A part-cylindrical shield member 23 is provided to close the gap between the part 20 when in the operative position and the fixed part 22. In Fig. 3 (not shown), the plane 16 of the intake duct is oblique to the engine axis. The intake duct however comprises a partcylindrical portion 24 which is pivotally mounted at 25 to the remaining fixed part 26. When noise suppression is required to be effective, the portion 24 is swung to the operative position indicated in broken lines so that the effective plane of the air intake is now that indicated at 27 the obliquity of which is greater than that of the plane 16.

Title: Self energising double disc brake
IPC: F16D55/14
Filed: 1962-05-15
Abstract: 1,019,982. Disc brakes; fluid pressure control of brakes. G. E. SETTLE. Aug. 1, 1963 [May 15, 1962], No. 18614/62. Headings F2E and F2F. A disc brake having self-energizing properties comprises a pair of coaxial spaced discs between which is located a first expander which applies pads to the inner disc faces, the first expander being pivoted to a fixed support for movement as a result of the drag forces acting on the pads, such movement being adapted to apply an amplified operating force to a second expander applying pads to the same or another pair of coaxial discs. In one embodiment, Fig. 2, a pair of discs 10 is formed integrally with a hub 11 and the inner faces are engaged by pairs of pads 15 associated with cylinders 13, 14 of which the former is pivotally mounted and supplied with hydraulic pressure by a master cylinder. The resulting drag forces on the pads causes pivotal movement of the cylinder to operate a second master cylinder for supplying pressure to the other cylinder 14. In Fig. 5 two such pairs of discs 27 are shown each having first and second cylinders 26, 30, respectively. First master cylinder 25 operated by pedal 23 supplies fluid to cylinders 26 which on pivotal movement operate separate master cylinders 29 which are interconnected by a pipe 31 leading via a balancing chamber 33 to a pipe 32 connected to the cylinders 30. A pipe 34 leads to other brakes on the vehicle while an additional control pressure is fed into the system via pipe 35, this being supplied by an oil pump driven from the transmission shaft, an inertia flywheel device, or a centrifugal governor, so that the pressure supplied to the cylinders 30 is dependent upon speed or/and deceleration of the vehicle. In a second embodiment (Fig. 4, not shown), a pair of discs 16 are joined by a peripheral annulus 17, the space between the discs which accommodates first and second cylinders 18, 19, being cooled by circulation of air through central opening 21 and peripheral ventilating tubes 22.

Title: Improvements in or relating to a magnetic storage matrix system
IPC: H03K17/81
Filed: 1956-06-15
Abstract: 839,457. Magnetic matrix stores. SPERRY RAND CORPORATION. June 15, 1956 [June 16, 1955], No. 18628/56. Class 40 (9). [Also in Group XIX] The columns and the rows of a matrix of magnetic storage devices M1-Mn to M1<11>-Mn<SP>11> are controlled by saturable reactors 10 to 12 and 13 to 15. The reactors are controlled by setting-leads 1 to n, A to X and the matrix is driven by trains of pulses from sources I1 and E4 in alternate set and drive periods S, D (see Fig. 2). The reactors are periodically driven into a state of positive saturation by the positive pulses from I1 and E4 but there is no substantial output in windings 23, 24 or 31, 32 of a reactor if the reactor is already positively saturated. If a reactor is set in a state of negative saturation, a drive pulse produces a substantial output. In reactors 13 to 15, the output produced by a drive pulse from E4 tends to make rectifiers D4, D5 non-conductive and thereby to prevent energization of the corresponding row of storage devices. A storage device M1 is marked by setting the column reactor 10 and setting all the row reactors but 13. Drive pulses from source I1, produce an output from reactor 10 to energize storage device M1, the rectifiers D4, D5 of reactor 13 being conductive. The polarity of the magnetomotive force applied to M1 is determined by pulses from sources E1, E2 which allow only one of the rectifiers D1, D2 to conduct. Negative pulses from a source E3 stop circulating current in the windings 31, 32 during the setting intervals. Winding 35 and a clamping rectifier 36 limit the voltages induced in the windings of core 30. In a modification, the pulse source E4 and the windings 33, 35, are eliminated. An unset core 30 offers little impedance to a pulse of one polarity energizing M1<11> and a set core offers a high impedance. The pulse sources E1, E2 provide the pulses to energize M1<11>. In another modification, the pulse sources E4, I1 and the windings 33, 35, 21 are eliminated, and the matrix is driven by pulses from source E1, E2, E3, as shown in Fig. 3. A storage element 66 may be set by means of an amplifier 67, Fig. 6, comprising output windings 62, 63, a setting winding 64 and a driving winding 65. Rectifiers 60, 61 are connected in series with the output windings and the direction of current flow through the storage device 66 is controlled by pulse sources E7, E8.
