Patent GB-934999-A (GB)
Title: An audiometer circuit, more particularly for an electronic transistorized metronome
IPC: G04F5/10
Filed: 1962-02-22
Abstract: 934,999. Metronomes. M. E. BERNSTEIN. Feb. 22, 1962, No. 7012/62. Class 139. [Also in Groups XV and XL (c)] In a speech training device the level of the speaker's voice is indicated on a meter 100 (Fig. 1), and to enable the speaker to maintain a desired rhythm, a loud-speaker 24 and/or a lamp 40 produce audible and/or visible (flashes) signals (metronome signals), the repetition frequency of which may be raised by respective controls 28, 46. Additionally, a clockwork timer 102 of the elapsed-time bell-signalling type including visual indication of remaining time is provided. For the indication of speech level the output of microphone 60 is supplied via a transformer 64 (Fig. 4) and level control potentiometer 66 to a two-stage transformer coupled amplifier including transistors 78, 86 and thence via transformer 90 to an integrating transistor stage 96, the collector current of which is indicated on the meter 100 which preferably comprises a D.C. mincroammeter. For producing the audible metronome signals a transformer coupled transistor blocking oscillator the R.C. constant of which may be varied by the control 28 and having a loud-speaker connected to the transformer is employed (Fig. 2, not shown), and for the production of the visible flashing signals a neon lamp circuit the R.C. constant of which may be varied by control 46 is employed (Fig. 3, not shown). A circuit producing both the audible and the visible signals (metronome signals) is shown in Fig. 5, and comprises a blocking-oscillator circuit including a transistor 110, transformer 112, capacitor 114 and adjustable resistor 115. A second transistor 122 is connected in series with the battery 118 and transistor 110 and is so biased by resistor 124 that the level of current flow from a battery 126 is insufficient to light a series-connected incandescent lamp 128 except on the occurrence of a blocking oscillator pulse. Ganged switches SW1, SW2 allow the production of the audible signals only or the visible signals only or the production of both signals simultaneously. When one signal only is selected, changes in the discharge circuit of capacitor 114 are prevented by switching in an equivalent resistance to replace the element not in use. When visible signals only are produced the loud-speaker is replaced by a resistor 132 and when audible signals only are produced the lamp 128 is replaced by an equivalent reistor (not shown).

Title: Improvements in weighing apparatus
IPC: G01G23/20
Filed: 1946-03-06
Abstract: 613,455. Weighing - apparatus. HOLDING DE PESAGE AUTOMATIQUE. March 6, 1946, No. 7051. Convention date, Jan. 14, 1939. [Class 143] Indicating mechanism for a weighing- machine comprises a series of number plates for each digit in the weight, the appropriate number plate in each digit is displayed under the control of a selector member and the several selector members are connected to corresponding feelers which are engageable with an apertured control disc rotated by the weighing mechanism. The control disc allows each feeler and its selector to move an amount dependent on the magnitude of its digit in the weight, so that each selector causes the appropriate numeral to be displayed. In the mechanism shown, a control disc 1 has four concentric groups of holes corresponding to four digits in the weight and is engaged by feelers at the forward ends of slides 2 connected to arms 4 of a set of multi-armed levers 7 rockable about the axis of a shaft 27d. Each feeler comprises a set of needles of graduated length, and its extent of movement is determined by one of the needles impinging on an unapertured part of the disc. A selector arm 28 is connected to each lever 7 so as to rock with it, the connection comprising the shaft 27d or a concentric sleeve 27a-c, an arm 26 rigid with the shaft or sleeve and a pin 25 engaging in a fork of an arm 6 of the respective lever 7. Opposite the path of movement of a pin 29 on each selector arm 28 are the tails of a series of pivoted pawls 37, each arranged to hold in an upper position, and out of view a number bearing plate 35, there being for each digit a series of these plates arranged one behind the other in vertical guides 36. The levers 7 are spring-loaded to urge their feelers 2 towards the disc 1, but a cam 9 on an operating shaft 11 normally holds them back with their feelers clear of the disc. A second cam 32 on the operating shaft normally holds the selector arms 28 with their connected parts 26 and 27a-d against the action of a spring 34 tending to move them as a unit axially to the right. In operation, the disc 1 is first allowed to come to rest and the shaft 11 is then turned by a handle 12. This first causes cam 9 to release the levers 7 which thereupon rock forwardly until the feelers are arrested by the disc 1. The selector arms 28 move with the levers 7, and their pins 29 are thus brought opposite the pawls 37 of the appropriate number plates as determined by the position of the disc 1 and the weight. Finally cam 32 releases the selector arms for axial movement by spring 34, each arm rocking a pawl 37 to release its number plate. The four released number plates fall to the lower part of their guides and into view to indicate the weight. The number plates are restored by lifting fingers 39 on a slide 40, operable by a handle 42 or by the final movement of the shaft 11. Printed records, apparatus for giving:- The weight is printed on a strip 17 by type heads 16 on arms 5 of the rocking levers 7 when a platen 18 is lifted up to them by a further cam 20 on the operating shaft 11.

Title: Aircraft control systems
Inventor: DOVE FRANK
IPC: B64C13/24
Filed: 1956-03-07
Abstract: 820,862. Automatic control systems for aircraft. SPERRY GYROSCOPE CO. Ltd. June 7, 1957 [March 7, 1956], No. 7242/56. Class 38 (4). [Also in Group XXXIII] Aircraft control apparatus includes two electric motors 221, 222 connected to drive a trimadjusting member slowly towards a position corresponding to the position of an appropriate control surface, and means deriving an electrical control signal dependent in magnitude and sense on the lack of correspondence between the member and the control surface and applying the signal to energize each motor, so that both motors normally act to drive the member in the same direction. The Figure shows a manual controller 201 and an elevator 202 generating electrical signals on potentiometers 206, 207, which are fed to a differential 218. During manual operation, a switch 233 feeds the output of the differential over contact 231 to a servomotor 210 driving the elevator 202 into correspondence with the controller 201. During automatic operation, the servomotor 205 is energized by switch 234 over contact 232 from an automatic controller 205 responsive to flight parameters or received signals, and the output of differential 218 is fed by switch 233 over contact 230 to two parallel control channels comprising similar amplifiers 223 and 224, and slowresponse motors 221 and 222. The motors control the position of a double-acting spring box 216b comprising a piston 216a the rod of which is pivoted to the manual controller. During automatic operation of the elevator, therefore, the neutral position of the manual controller is driven to a position corresponding to the long-term average position of the elevator, whereby manual control can be smoothly engaged at any time, and the " feel " will be suitably trimmed. Alternatively, the motors 221, 222 may drive an elevator trim tab to relieve long-term deflection of the elevator under automatic control, whereby manual control can be resumed equally smoothly. The amplifiers 223, 224 are arranged to be saturated by a low input voltage, whereby if a fault develops in one control channel, resulting in a maximum output from that channel, a small deviation in trim will result in an opposite maximum output from the other channel, and the trim error is held to a minimum. Specification 803,574 is referred to.
