Title: Improvements in or relating to apparatus for automatically controlling aircraft
IPC: G05D1/08
Filed: 1941-06-19
Abstract: 596,358. Fluid-pressure servomotor-control systems. HORSTMANN, B. G. June 19, 1941, Nos. 7751, 7752, 7753, 7806 and 7807. [Class 135] Automatic flight control apparatus for aircraft is provided with means operable by the manual controller of the aircraft for imparting to an air or electrical pick-off a displacement corresponding to that of the manual controller. Said means may be thrown out of action at will. The form shown in Fig. 1 comprises a pick-off member 4, an air relay 5 having needle valves 5a for controlling an oil valve 6, a servomotor 7 with pistons 7b ported to coact with needle valves 7a and a manual controller 17 acting through mechanism 12, 13, 14 for setting the member 4, the mechanism 12 being such that the controller 17 can simultaneously operate the member 4 and control surface 9, whereas the control surface can operate the controller but not the member 4. As shown in Fig. 2, a differential 16 is connected to the mechanism 12 and to the followback drive 15, and means such as described in Specification 455,673 may be provided to allow manual operation of the control surface 9. One form of mechanism 12 has a shaft D, Fig. 3, connected to the servomotor and control surface, a plate A and shaft B connected to the manual controller, and a member K connected to the pick-off member and capable of being clutched to a fixture H. Balls F fit with a nlight clearance in wedge-shaped pockets in the shaft D and plate A between which is a positive clutch C with small play, balls Q are disposed between the member K and plate A, a spring G acts on the plate A and pins P, N carried by the member K and plate A respectively are gripped between jaws on plates I, J pulled together by a spring O. In a modified form of the mechanism 12, the member K may be clutched to an auxiliary member U, Fig. 5, included in the follow-back train, the balls F are arranged between the fixture H and a plate S and a clutch plate T<1> is arranged between the plate S and a member R. A clutch which transmits motion from shaft B to the member R and thence to the member K comprises a pair of toggle members G<1> pivoted on the Mange B<1> of the shaft and coacting with the inner cylindrical surface of the member R. When motion originates in the shaft D, a striker E<1> carried by the shaft disengages one or other of the toggles, and the members R, K are not driven. In both forms of the mechanism 12, the member K can be locked in position to prevent the manual control from operating the pick-off member.

Title: Improvements in and relating to electronic triggered relay devices
Inventor: ADAMSON COLIN
IPC: H03K3/288
Filed: 1958-03-11
Abstract: 903,001. Transistor relay circuits. ENGLISH ELECTRIC CO. Ltd. March 6, 1959 [March 11, 1958], No. 7790/58. Class 40 (6). Fig. 1 shows a trigger circuit for controlling the operation of a relay 10 in dependence upon the presence of a negative-going control signal applied at input terminal 12. Initially the reciprocally-coupled transistors 11a, 11b are in the stable state in which transistor 11b is conductive and 11a cut-off, and in which transistor 13 connected in the H.T. supply between terminals 14a and 14b is also normally non-conducting. When a negative control pulse is applied at terminal 12 the bi-stable transistor circuit 11a, 11b changes to its second stable state in which transistor 11a is conductive and transistor 11b non-conductive, so that relay 10 is operated, provided that transistor 13 is also rendered conductive by the negative pulse at 12. In the modification shown in Fig. 2, for use in connection with a carrier current phase comparison relay system such as described in Specification 902,998, the transistor 13 in the H.T. supply has an independent control signal applied to it at terminal 16 in addition to the input signal applied at terminal 12 to trigger the bi-stable circuit 11. A negative inter-tripping signal applied at terminal 19 to render transistor 18 conductive enables relay 10 to be energized independently of the trigger circuit 11 if so required.

Title: Improvements in or relating to starting internal combustion engines
IPC: F02B71/00
Filed: 1944-04-27
Abstract: 570,831. Engine starters. WUHRMANN, K. April 27, 1944, No. 7938. [Class 7(v)] The barring apparatus for a free-piston internal-combustion engine 1, controlled by a barring member 16 in a casing 17, consists of barring pistons 14 working in a barring cylinder 12 and connected by a rack 13, a train of gearwheels 6, 7 and 8, of which the pinion 7 is mounted on the shaft of one of the couplings 5, a pinion 11 and a coupling 10. A liquid or gaseous pressure medium is supplied at low pressure to the coupling 10 by a pipe 22 and to the casing 17 by a pipe 23, and at a higher pressure through a pipe 24 to the barring cylinder 12. By moving the barring member 16 into any one of feed positions, it is possible to control the operation of the barring mechanism in such a manner as to bring the free pistons 4 into their starting position. In certain positions, the pin 34 engages the slot 31 and thus prevents a ratchet disc 29, and a starting shaft 27 to which it is attached, from moving into the starting position A. The safety device 33 prevents starting until the jaws 36 of a piston 35 in the coupling 10 are withdrawn from the recesses 37 in the pinion 6 which is then able to rotate independently of pinion 11.

Filed: 1943-05-20
Abstract: 577,242. Directive wireless signalling. LINK AVIATION DEVICES, Inc. May 20, 1943, No. 8029. Convention date, April 29, 1942. Drawings to Specification. [Class 40 (v)] Apparatus for instructing and training pilots in flying with the aid of radio signals comprises a " trainer " (a manoeuvrable dummy or model aircraft controlled by the student, such as described in Specifications 370,128, 481,375 and 484,243, [all in Group XXXIII]), having a radio receiver, and means, controlled by the instructor, for transmitting, by radio, signals such as would be received by a pilot in real flight, particularly those received from equi-signal beacons and inner, outer, and Z-markers. The instructor has a microphone which can be either used to modulate the wireless transmitter or connected direct to the interphone of the pupil for direct instruction by telephone. A switch, under control of the pupil, permits the carrier to be modulated by the microphone and/or signals simulating the beacon or marker signals. In order to produce marker signals having different carrier as well as different note frequencies, a ganged switch may be arranged to select a source of note signals and simultaneously tune the carrier amplifier to the desired carrier. Atmospherics and undesired signals may be imitated by connecting selected noise generators to the modulating amplifier. To train pupils in direction-finding and determining a " fix ", the instructor can transmit signals such as would be obtained in direction-finding and the pupil has a directive loop mounted in his trainer. - The instructor's apparatus has various volume controls whereby he can vary the relative strengths of the overlapping beam signals, or can simulate fading &c. The instructor can simulate signals from two radio beacons on different frequencies, and can transmit station-identifying signals corresponding to the different beacons on the assumed route, these station calls and the A-N or like signals being determined by rotary cams controlling the modulating frequency. The " trainer " is connected to a recorder at the instructor's desk, so that the instructor can follow the " flight " of the pupil and transmit signals such as he would receive in actual flight.

Abstract: 952,711. Voice-frequency signalling. STANDARD TELEPHONES & CABLES Ltd. March 2, 1962 [March 8, 1961], No. 8162/62. Drawings to Specification. Heading H4K. In a V.F. signalling system in which digits are represented by combinations of frequencies, e.g. 2 out of 6, and in which a signal continues until acknowledged by a signal from the receiving end, a separating signal is interposed between successive digit signals, so that in the event of a break in the transmission channel the resumed digit signal shall not be misinterpreted. The receipt of the separating signal initiates a backward signal which in turn starts the sending of the next digit signal. The separating signal and backward signal must comprise different frequency combinations if the same channel is used for signalling in both directions.
