Title: Improvements in or relating to aircraft navigational aid apparatus
Inventor: SEDGFIELD HUGH BROUGHAM
IPC: B64D45/00
Filed: 1953-04-24
Abstract: 745,389. Electric control systems. SPERRY GYROSCOPE CO.. Ltd. March 1, 1954 [April 24, 1953], No. 11343/53. Class 40(1) To enable an aircraft pilot to execute a desired rate of climb or dive, a knob 10 is set manually to the desired rate to produce an electric signal corresponding thereto, from which a signal is derived proportional to the difference between the actual aircraft altitude and a continuously changing set altitude. This signal is combined with a pitch deviation signal and fed to a central zero indicator, the pilot merely operating his pitch controls to keep the instrument reading at zero. As shown,- a potentiometer P1 is set by the knob 10 to produce a D.C. voltage of magnitude and polarity corresponding to the desired rate of climb or dive. This voltage is integrated by a motor 11 which through a cam 12 continuously moves the upper end of a barometric capsule 13 in accordance with a set altitude continuously changing in dependence on the setting of knob 10. The capsule responds to the actual altitude so that the pick-off 14 operated thereby gives an output proportional to the difference of the actual and set altitudes. The pick-off output is combined differentially with the pitch signal from the gyro-vertical G1 the resultant being amplified at Al and fed through a phase sensitive rectifier 18 to the coil 19 of the horizontal pointer 21 of a cross-pointer instrument 20, the vertical pointer of which is irrelevant to the invention. The pilot operates his rate of climb controls to keep the pointer 21 reading at zero when the pitch signal from the gyro vertical equals the pick-off output. When the rate of climb is set to zero, the motor 11 is stationary, and the meter responds to variations in altitude as in Specification 690,985 [Group XXXIII]. The cam 12 may have a non- linear law to compensate for non-linearity in the capsule characteristic and the motor may drive a potentiometer (not shown), which modifies the pick-off output to vary the sensitivity of the system at different altitudes. The D.C. rate-of-climb signal from the potentiometer P1 may be also connected through a modulator M1 and resistor R1 so that the pointer 21 is deflected immediately the knob 10 is set to a value (other than zero), the signal via M1 - R1 acting as a coarse control and the pick-off signal 14 as a fine control. In a modification, (Fig. 2 not shown) the integrating motor drives a potentiometer in lieu of the cam 12, the potentiometer output representing the set altitude being added algebraically to the pick-off output to give the altitude difference signal.

Abstract: 309,557. Marconi's Wireless Telegraph Co., Ltd., (Assignees of Hansell, C. W.). April 12, 1928, [Convention date.]. Thermionic modulating systems. - In a modulating-system a sum or a difference frequency alone is obtained by producing each of the energies in three-phase form, modulating corresponding phases, and combining the outputs. The Figure shows modulator valves 10, 20, 30, to which a source of three-phase highfrequency energy 40, is applied through blocking condensers 46. The signal energy source 50, is connected to a phase-multiplier 60, which supplies three-phase energy to the modulating- valves through chokes 48. The outputs of the modulating valves are combined and applied to a high-frequency amplifier 86. By modulating each phase of the energy-source with a corresponding phase of the other source, to which equivalent phase rotation in like direction is applied, a difference frequency is obtained, and by associating phases in opposite rotation a sum frequency is obtained. The Specification as open to inspection under Sect. 91 (3) (a) comprises also the use of the energies in other polyphase form. The subject-matter does not appear in the Specification as accepted.

Abstract: 576,364. Helicopters. UNITED AIRCRAFT CORPORATION. July 21, 1943, No. 11878. Convention date, Dec. 28, 1942. [Class 4] A helicopter provided with manually-controlled mechanism for effecting cyclical and simultaneous pitch adjustment of the blade also comprises automatic means interconnected therewith for reducing the blade pitch in the event of the coning angle of the blades reaching a predetermined value and at the same time varying the setting of the manual control. Cyclical pitch variation is effected by means of a tiltable ring 28 actuated by a control lever 22. through crank arms 24, 25, simultaneous pitch adjustment being obtained by translational movement of the ring 28 through a second hand lever 54. The movements of the ring 28 are transmitted to the blades 18, 20 by means of levers 32, which operate cross-shafts 34 and levers 35, 36, 37, to rotate the blades about drag links 52. A second ring 38 pivoted at 60 to the rotor driving shaft carries arms 39, to the ends of which are attached cables 40 joined to the pitch-changing levers 37. In the event of the coning angle of the blades exceeding a predetermined value, the cables are drawn taut to decrease the pitch angle in proportion to the increase in coning angle and automatically vary the setting of the manual control mechanism. This ensures autorotation of the blades in the event of failure or partial failure of the engine. A torque compensating propeller 62 is provided at the tail of the machine.

Title: Timer
IPC: G04C23/16
Filed: 1953-05-01
Abstract: 728,105. Timed control of electric circuits. VEEDER-ROOT, Inc. May 1, 1953 [May 1, 1952], No. 12084/53. Class 118 (2). A process timer comprises two setting means and a clock mechanism arranged so that the occurrence of a first actuating movement can be set to take place at a selected time relative to clock time and the occurrence of a second actuating movement can be set to take place at a selected time interval after the first actuating movement. A first setting means is displaced an amount proportional to the time interval and is driven back when engaged by the clock mechanism acting through a differential coupled with a second setting means which thereby determines the clock time at which the drive engages. The embodiment described comprises a timer for electric cookers whereby a preset cooking period may be completed at a predetermined finish time. The cooking period is set on the scale 80 by pushing in knob 61 to free the disc 62 from detents 63 and 64 and then rotating the knob. On release of the knob 61 the detent 64 abuts one of the teeth 70 and maintains the shaft 50 against action of the spring 60. In this position the cam 51 opens the switch contacts 41<SP>1</SP>, 421 as in Fig. 8 (not shown). An electric clock movement 16 drives a disc 90 through a friction clutch 20 and gearing including a differential 100 having a second input from knob 121. Time-indicating hands 23 and 30 are also driven by the movement 16. The disc 90 is loosely mounted on shaft 50 and carries an arm 92 which, after a period dependent upon the setting of knob 121 in relation to clock time, engages a pin 91 carried by disc 62 and commences to return the disc 62 to its initial or "off" position. The first rotary movement of disc 62 allows detent 64 to enter a slot between teeth 70 and hence permits some axial movement of shaft 50 to the position where disc 62 bears against detent 63 which is shorter than detent 64 in the axial direction but extends further inwards radially; in this position of shaft 50 the cam 51 allows contacts 41<SP>1</SP> and 421 to close. The disc 62 then continues to rotate under the clock-drive (the detent 64 being pivoted to ride over teeth 70) until a deep elongated notch 71 arrives at detent 63 (as in Fig. 7) and disc 62 with shaft 50 moves to its most forward position wherein cam 51 opens contacts 41<SP>1</SP> and 42<SP>1</SP> and pin 91 is out of the path of arm 92. The arrangement of the gearing between the clock, movement 16, second setting means 121 and disc 90 is such that this final switching off movement of shaft 50 occurs when the clock time synchronizes with the time set on scale 130 by means of knob 121. The elongated notch 71 permits knob 61 to be rotated in the opposite direction to that for setting a cooking period, to a position designated " manual " wherein a cut-away 52 on cam 51 allows contacts 41<SP>1</SP> and 42<SP>1</SP> to close for non- automatic operation of the cooker; a nose 53 on cam 51 operates a switch 40 to light an indicator lamp when in this position.
