Title: Electrical musical instrument
IPC: G10H1/38
Filed: 1941-05-14
Abstract: 549,363. Electrical musical instruments; organs. HAMMOND, L. May 14, 1941, No. 6214. Convention date, July 24, 1940. [Class 38 (ii)] In an electrical musical instrument of the keyoperated type the production of accompaniment tones additional to those tones normally produced by the operation of the keys 10 and selected automatically by the operation of those keys is controlled by a pedal 46 which is spring-returned so that depression of the pedal each time an accompaniment tone is required can control the duration of such tone. As shown in Fig. 1, the accompaniment tones are produced by electrostatic generators CO...BO beyond the range of the manual generators C1....B4, and by the provision of single-pole double-throw switches 36 operated by the keys, the lowest key operated selecting the accompaniment generator to which the energizing potential from a battery 48 will be applied when the pedal is depressed. A battery 20 is connected to the bus-bar 18 for energizing the manual generators through switches 16. In the arrangement shown, two octaves of the manual keys have connections with a single octave of bass accompaniment note generators. To prevent the sounding of unwanted notes the pedal is preferably depressed for each bass note desired. Instead of the accompaniment generators being one or two octaves below the pitches of the selecting manual keys they may be harmonically related to those pitches. In a modified circuit for use with electrostatic generators the battery 48 is connected to ground through a resistance and through a normally closed switch which is adapted to be opened by depression of the spring-returned bass pedal. The electrostatic generators may be of the construction set out in Specifications 501,520 and 529,167. The invention may also be applied to an electrical musical instrument wherein the output of continuously operating electromagnetic gener-' ators of the kind set out in Specification 454,502 is transmitted to the output circuit of the instrument under the control of key-operated switches. Further, instead of giving accompaniment tones one or two octaves below the lowermost of the bass register keys depressed the arrangement may be such that a note higher than the highest depressed key, but harmonically related to it, will be sounded when the pedal is operated.

Title: Improvements in or relating to geophysical survey apparatus
Inventor: SNELLING ERIC CHARLES
IPC: G01V3/165
Filed: 1955-03-04
Abstract: 829,861. Geophysical surveying apparatus. MULLARD RADIO VALVE CO. Ltd. Feb. 27, 1956 [March 4, 1955; Aug. 5, 1955], Nos. 6460/55 and 22612/55. Class 37. Apparatus for geophysical surveying from aircraft comprises a transmitting coil T supplied by a low-frequency generator G, a receiving coil O, a coil S picking up a reference voltage directly from the transmitting coil and an adjustable phase - shifting attenuator V for automatically balancing the reference voltage and the voltage picked up by the receiving coil for long term variations. The difference between the reference and received signals is filtered, amplified and fed to a phasesensitive detector which separates the in-phase and quadrature components of the resultant signal. These components operate separate pen recorders P1, P2 and also, at a certain level, operate motor controlling relays to adjust elements in the attenuator V in the direction of balance between reference and received signals. This action is sluggish and does not normally affect the records during the passage of the aircraft over a body of ore. The phase-shifting attenuator is provided with manual control in addition to automatic control for initial balancing and integrating networks 12, 15 in the circuits to the pen recorders may be switched to have a number of integrating times. The pen recorder amplifiers A2, A5 are A.C. coupled to prevent any steady out-ofbalance current from appearing on the record. The pick-up coil is supported at one wing tip of an aeroplane and the energizing coil at the other wing tip and two sets of apparatus are normally used one operating at a frequency of 214 cycles per second and the other at 320 cycles per second, the coils for one apparatus being arranged vertically and the coils for the other horizontally. The coils are made as iron-cored solenoids the cores being in the form of rods with the windings towards the outer ends. Two rods are arranged in cruciform shape, one rod carrying the coils for one frequency and the 'other carrying the coils for the other frequency. The cruciform assembly may be attached to the aeroplane wing as described in Specification 829,862.
