Title: Stringed musical instrument with elecgronic time-division multiplexing circuitry
IPC: G10H1/18
Filed: 1975-05-03
Abstract: 1478722 Stringed musical instruments W L AVANT 3 May 1975 18600/75 Heading G5J A stringed musical instrument (an electrical guitar as shown) comprises a set of electrically conductive strings 10 and electrically conductive fingerpads 20 on a fingerboard 7 coupled to circuitry giving a cyclical time-division multiplex digitally encoded output indicating sequentially the fingerpad with which each string is in contact. In the embodiment shown a guitar 5 comprises pick-up elements 30 for generating a contol signal in response to the vibration of each string, a connector 37 for connecting the strings and fingerpads to the circuity, and pick-up elements 33 and a connector 35 for connection to a conventional guitar amplifier and speaker (not shown). Switching pulses sb-1 to sb-6 are applied sequentially to the strings 10-1 to 10-6 to activate the fingerpad (if any) on to which the string is depressed, the pulses sb-1 to sb-6 being produced by the circuit of Fig. 3A (not shown) which comprises a clock (50), a cyclical counter (52) and decoders (55-1 to 55-6) and is represented in Fig. 2 as a commutator 45. The fingerpads are connected via respective diode gating arrangements 27-1 to 27-21 to inverters 64-1 to 64-5 such that the outputs 65-1 to 65-5 of the inverters represent the binary digits of the number of the currently activated fingerpad, these outputs constituting a cyclical time-division multiplex parallel-by-bit digitally encoded signal EDI indicating sequentially which pad is connected to each string in turn.  The signal EDI is connected to a harmony computer 70 which comprises logic gates (103 to 106, Fig. 6, not shown), an adder (100) and a decoder (105) which identify which of the twleve notes of an octave is being played, twelve single pole three-position switches (110-1 to 110-12) which can be set to sharpen or flatten each note by a semi-tone or leave it unchanged, and switches (41, 42) which sharpen each note by three or five semi-tones respectively when closed the output 73 of the harmony computer comprising a parallel by bit digital signal ED2 similar in form to the input ED1. The output signal ED2 is applied to a decommutator comprising six memory cells 75-1 to 75-6, the output of each memory cell 75-i a five-digit binary output related to the note played on the corresponding string 10-i, as modified by the harmony computer. The output of the memory cells is applied to a decoding gating arrangement 80 connected to an output bus 90 having a separate wire for each possible note, a logical "1" on a wire indicating that the note is being played. A memory switch 40 is provided which, if closed, causes an output to be obtained on the output bus 90 whenever a string is pressed into contact with a fingerpad, whether or not the string is vibrating. The output 90 can be used to effect remote playing of another instrument.

Title: Improvements in or relating to the manufacture of aliphatic anhydrides
IPC: C07C51/573
Filed: 1927-07-14
Abstract: 298,667. British Celanese, Ltd., Dreyfus, H., and Haney, C. I. July 14, 1927. Grant of Patent opposed. Acetic and other aliphatic acid anhydrides are produced by heating the vapours of the acids, which may be dilute, and the anhydrides are condensed and separated from the water by passing the vapours under the surface of a cooled " extraction liquid " such as benzene, chloroform, or mixtures of ether or chloroform with one or more light hydrocarbons, such as petroleum ether, gasoline, or benzene or its homologues. The anhydrides dissolve in the extraction liquid " while the water condenses to form a separate layer. The extracting liquid or the water or both mav be continuously withdrawn. The invention is described with reference to acetic anhydride. Acetic acid is converted into anhvdride in a tube 1 which may be of copper, fireclay, or the material sold under the Registered Trade Mark Vitreosil, heated to 400-1200‹ C., and the vapours pass to a vessel 3 in which vapour of the extraction liquid is added by a pipe 4. The mixed vapours pass by a pipe 5 into the extraction liquid 6 in a vessel 7 having a cooling-jacket 9 and a stirrer 10. The pipe 5 dips below the surface of .the extraction liquid; if the extraction liquid is heavier than water, the pipe should be only a little below the surface, while if the liquid is lighter than water the pipe should dip deeply into the liquid so as to allow the water layer to be out of the way of the incoming vapours. The extraction liquid may be continuously withdrawn by an overflow 12, 13, the anhydride being finally separated by distillation. The water may be continuously withdrawn by a pipe 11, 11<a> to a vessel 15, and meets a stream of extraction liquid coming from a tank 16 by way of a pipe 17 and rose 18. The extraction liquid passes upwards through the pipe 11<a>, 11 into the vessel 7.

Title: Terminal shield for submarine cable
IPC: H01B11/10

Abstract: 357,229. Preventing inductive disturbance. STANDARD TELEPHONES & CABLES, Ltd., Columbia House, Aldwych, and BLUMLEIN, A. D., 20, Lyncroft Gardens, Hampstead, both in London. June 19,1930, No. 18701. Drawings to Specification. [Class 40 (iv).] A metallic shield located between the armour and conductors of a submarine cable at the shore end for preventing inductive disturbance is connected to the armour at the deep sea end and connected to the armour or earth through an impedance at the shore end. The impedance minimizes the detrimental effects of shield-armour capacity on the efficiency of the shield. A number of such shields may be interposed between the armour and conductors and may be of different lengths and materials, each shield at the shore end being connected by an impedance to the next outer shield or earth. The conductivity (thickness) of the shield increases, and the insulation thickness between armour, shield, and conductors decreases towards the deep sea end, the rate of variation depending on the rate of descent of the cable. The conductors may be reduced in size at the shore end. The shield may be made up of laminations of the same or different metals, for example, copper or a layer of nickel-iron alloy between layers of copper. The impedance between the shore end of the shield and earth may be an inductance resonating with the capacity but, in order to increase the frequency range of its effectiveness, it may be a network of inductance, positive and negative resistance, equivalent to a positive reactance which decreases with frequency. The two windings of the repeating coil at the cable terminal may be separately screened, the screen on the land side being earthed and that on the cable side being connected to the cable shield.

Filed: 1917-12-21
Abstract: 120,816. Davies, W. Langdon-, and Soames, A. Dec. 21, 1917. Electro-magnets; dynamos, driving. - In an electro-magnetic friction clutch, the strength of the exciting current of which may be varied from the lower end of the scale to the top and thence back again to the bottom, any change in the exciting strength always takes place in the same direction in the cycle of operations, in order that the magnetic flux produced by a given adjustment of the switch controlling the current may be invariable. The clutch exciting coil A is connected to the ends of pointers C, C<1> secured to a ratchet wheel D allowed by a pawl D<1> to move only in one direction. The pointers C, C<1> traverse a continuous resistance E, to opposite sides of which are connected the terminals of a battery F. The current in the coil A may be varied between positive and negative maxima by suitable adjustment of the pointers C, C<1>. In the diagram, exciting strengths are measured along the co-ordinate B, B and fluxes along the co-ordinate H, H, opposite excitation being required to overcome the residual magnetism of the coil after either positive or negative excitation. To obtain any required attraction in the coil, the switch must necessarily be moved so that the excitation follows the course of the arrows in the diagram. In the device shown in Fig. 2, the main clutch coil A<1> is actuated from the mains F<1> by a switch C<2> of the kind described, an opposing coil A<2> on the driven shaft K<1> being excited from a small dynamo L on the driven shaft through the intermediary of a second switch C<3>, the pointers of the two switches being preferably coupled to move together. When slip occurs in the clutch, the strength of the dynamo current falls and the clutch is automatically tightened to prevent excessive slip.
