Title: Improvements in apparatus for computing and indicating the ratio of dynamic pressure divided by static pressure
IPC: G01P5/175
Filed: 1954-04-12
Abstract: 764,491. Aircraft indicators. MECHANISM, Ltd., and GRANDIDGE, J. E. July 12, 1955 [April 12, 1954], No. 10766/54. Class 4. An aircraft indicator comprises means for computing and indicating from the static pressure, the Mach number corresponding to the critical airspeed (being the indicated air speed which may not be exceeded without causing structural damage due to pressure build-up across the airframe) wherein means is provided to vary the indication given for various critical airspeeds corresponding to individual aircraft. In Fig. 1, a pointer 29 is set in a scale 28, in accordance with the critical air speed of the particular aircraft. This rotates a cam or eccentric 7 raising or lowering bodily a plate 6 on which rests a rod 5 contacting at its upper end a plate 8 secured to a cylinder 9 rotatable on an axle 10. This axle is attached by a link 11 to a toothed quadrant 12, meshing with a gear wheel 13 from which extends a pointer 14 on a Mach number scale 15. Rod 5 slides in a cylinder 4, which is adjustable along the length of plate 8 by a linkage 2, 3, controlled by a static pressure sensitive capsule 1, so that the throw of plate 8 for a given movement of plate 6 is varied in accordance with static pressure, so that the critical airspeed indicated on scale 28 is converted to the corresponding Mach number on scale 15. A capsule 16 sensitive to dynamic head operates a plate 18, rod 19, plate 21, and through a linkage as before, a pointer 26 indicating the flight Mach number on scale 15. In addition, a pointer 49 indicates the indicated air speed on a dial 50 for take-off and landing purposes. A practical embodiment is illustrated in Figs. 2 and 5, where parts corresponding to those of Fig. 1 have the same references. The indicator 28 on scale 29 assumes the form of a window in scale 15 through which the reading of scale 28 can be read. In addition, a pointer 54 adjustable by knob 53 shows a Mach number which may not be exceeded without excessive kinetic heating. The disposal of the parts is shown in Fig. 5. The double capsule 1 controls a cradle 3 to which are attached the cylinders 4 and 20. As before, a rod 19 in cylinder 20 extends between plate 18 and plate 21, the latter being secured to a shaft, the rotation of which actuates quadrant 24 and pointer 26 through shaft 39 and a triple linkage 23. Similarly, a knob 64 adjusts plate 6 through a screw and nut mechanism, this motion being transmitted through the rod 5 in cylinder 4 to plate 8 on shaft 9, and through the triple linkage 11 to the quadrant 12 and pointer 14. Knob 64 also rotates the scale 28. A further capsule 43, Fig. 4 (not shown) operates in conventional manner a pointer 49 working on a scale 50 to show indicated air speed over a range suitable for take off and landing.

Filed: 1953-04-22
Abstract: 724,590. Timed control of electric circuits; road signals for controlling traffic. ALBISWERK ZURICH AKT.-GES. April 22, 1953 [May 31, 1952], No. 11136/53. Class 118 (2) A timing relay circuit arrangement suitable for use in the control of traffic signalling lights comprises relays adapted to apply a potential, after different predetermined intervals of time calculated from a starting signal, to lines allocated to these intervals of time. The starting signal is provided by closing the contacts s which start the impulse emitter relays T1, T2, T3 and F1 to F4. The impulses step forward a chain of metering relays, A, B, C and D, this chain being passed through several times in the case of time intervals longer than the time for one passage through the chain, a chain of auxiliary relays H1 to HS and U being stepped forward after each passage through the metering relay chain. The contacts of the metering and auxiliary relays serve to distribute each potential to the appropriate one of the lines indicated by the reference numerals on the right-hand side of the figure. The closing of contacts s energize relay E1 which, in turn, energizes T2 which energizes T3. Relay T3 breaks the circuit of Tl which is rendered slow-to-release by the resistor Wi1 across one of its two windings; relays T2 and T3 are also slow-to-release. The relays F1 and F2 are controlled by contacts of relay T2 and are arranged such that F2 operates at half the frequency of T2. Relays F3 and F4 similarly divide the frequency by two again. By adjusting resistor Wi1, relay F4 is made to have a period of two seconds (one second operative, one second inoperative) and the reference numerals applied to the controlled lines are indicative of the time in seconds after which earth potential is applied thereto.

Abstract: 663,471. Television. RADIO CORPORATION OF AMERICA. April 28, 1949 [May 28, 1948], No. 11331/49. Drawings to Specification. Class 40 (iii). [Also in Group XL (c)] The blanking and/or synchronizing signals of a conventional television transmission system are modulated by alternative image signals. In the arrangement described the alternative image signals (e.g. news briefs, sport scores, &c.), which are generated by means of a separate camera operated synchronously with the main camera scanning operation, are arranged to amplitude modulate the blanking or synchronizing pulses associated with the main camera scanning operation in opposite polarity to the main image signals and reproduction of the alternative image signals at a receiver is effected by reversing the polarity of the signals fed to a cathode-ray picture reproducing tube so that the main image signals extend into the blacker-than-black region. The means for reversing the polarity of the signals may comprise a switch arrangement which selects either the positive or negative signal output of a diode video detector, Fig. 4 (not shown) or, which selects one of the outputs from two oppositely poled detectors, Fig. 5 (not shown). In each of the latter arrangements the bias on the picture reproducing tube is suitably varied to preserve the black reference level of the alternative image. The alternative image may also be transmitted by modulating the blanking &c. signals in the same polarity as the main image signals reproduction of the former signals in this case being effected by increasing the brilliance of the main image until the alternative image becomes invisible (i.e. is superimposed on the main image), a clipping action which clips all " white " signals alone, a predetermined level being provided if desired. U.S.A. Specifications 2,061,734, 2,227,108 and 2,257,562 are referred to.
