Title: Eectrical musical instruments
IPC: G10H1/38
Filed: 1963-07-04
Abstract: 1,044,665. Electrical musical instruments. JOH MUSTAD A.B. July 4, 1963 [July 4, 1962], No. 26595/63. Heading G5J. An electrical musical instrument, in which the transmission of electrical signals corresponding to tones which are fed to sound-reproducing means of the instrument are controlled by switches operated by buttons or keys, comprises a chord button system in which each button operates two or more of the switches for transmitting two or more tones in the form of a chord and chord-modifying means which modify the cord obtained by operating a chord button when this button and the chordmodifying means are operated simultaneously. Three rows of self-returning buttons, Fig. 1, are provided to operate contacts in the manner shown in Fig. 2. The lowest row of buttons forms minor chords and the intermediate row major chords, the basic tone of the chord being indicated on the respective buttons, there being one button for each basic chord in the chromatic scale, each chord consisting of three tones. The chord-modifying means consist of a row of buttons 1-12, each button upon actuation transmitting one tone, the semi-tone above that tone being automatically eliminated from the resulting chord if it should be contained in the chord corresponding to a chord button actuated simultaneously with the chord-modifying button. The tones obtained by actuating the chord-modifying buttons are indicated under the buttons and those eliminated are indicated in brackets above the buttons. Fig. 2 shows the circuit diagram in which twelve tone frequencies C-H of the chromatic scale are connected to conductors L, through resistances R1 and R2, which can be connected to conductors M by means of contacts K operable by the buttons, conductors M being permanently connected to the output terminal O. The chord-modifying buttons, e.g. 6 and 7, operate switches K6, K7 which are connected to ground and to the position P (connection not shown) between the resistances R1 and R2. Examples of the chords produced are given in the Specification. In a further embodiment, Figs. 3 and 4 (not shown), the chord-modifying means consist of two bars situated near the chord buttons and pivotally mounted around a longitudinal axis such that when pressure is applied to a longitudinal edge the bar pivots and modifies the chord. The electrical signals may be produced by vibrating tongues or strings, with electric or magnetic transducing means detecting the tone frequency spectrum, or by electronic oscillators coupled to frequency dividers.

Title: A heavy fuel burner
IPC: F23D11/00
Filed: 1957-08-29
Abstract: 833,087. Spray and pulverulent fuel burners. PETRO-CHEM PROCESS CO. Inc Aug. 29, 1957 [Oct. 4, 1956], No. 27217/57. Class 75(1) A heavy liquid fuel or pulverulent fuel burner with an atomizer nozzle 12 discharging a spray into a venturi passage, normally discharging at the throat 15 thereof, and with air entering at the remote end of the venturi passage and the combustible air/fuel mixture burning at the discharge end has a portion of the nascent combustion products leaving at such discharge end recirculated to a region just below the venturi throat e.g. through enclosed channels 40 at the exterior of the heat resistant refractory or stainless steel block 13 in which the venturi passage is provided. and thence through ducts 41. The recirculated products heat the incoming air and revaporize any liquid drops that may have formed. The nozzle is carried on a fuel pipe 11 which is axially adjustable to vary the position of the nozzle, and so of the flame, for different fuels; thus for light vaporizing fuel the nozzle may be raised to such an extent that none of the combustion products is recirculated. The refractory block 13 with its recirculating passages 40 is surrounded by a heat resistant cylinder 42 with a frusto-conical cowl 43 overlying the radially inner side of the recirculation passages whereby a portion of the nascent combustion products is deflected for recirculation. The burner is mounted from the floor 49 of the furnace by a construction comprising steel cylindrical rings 53, 54 apertured for hit-andmiss regulation of primary air to the venturi passage and steel rings 24, 58 for similar regulation of secondary air. A muffle cylinder 48 surrounds the burner. Steam may be used for the atomization. A modification (Fig. 3, not shown) has only one air admission and angularly set vanes impart a whirl to the entering air.

Title: Improvements in road traffic signalling installations
IPC: G08G1/081
Filed: 1952-10-29
Abstract: 719,121. Road signals for controlling traffic. SIEMENS & HALSKE AKT.-GES. Oct. 29, 1952 [Oct. 31, 1951], No. 27236/52. Class 118 (2). Centralized supervision and control of traffic signals is obtained without the disadvantage of a multiplicity of cables by providing group control apparatus in the neighbourhood of sets of signals automatically controlled thereby, and connecting all the group control stations in common to a central control station with individual lines from group stations to the central station whereby any selected group station may be switched onto the common cabling circuits for supervision and control of that particular group station. Each group station GS comprises an automatic programme selector P to regulate several sets of signalling apparatus S (only one set being shown in the Fig.) in respect of total phase time and the phase time ratio. The programme selector is stepped forward by an electromagnet PW on each closure of a time switch z driven by a clock mechanism. Two contact banks b3 and b4 of the programme selector P are connected by common cabling to the central control station Z through contacts of a relay AN which is controlled over an individual line a1 from the control station Z. If switch n is operated the relay AN is energised and potentials from contact banks b3 and b4 are fed to non-polarised relays N1, N2 and to polarised relays P1, P2 at the central station Z whereby the potentials are analysed to indicate the condition of selector P from the nine possible permutations of no potential, positive, or negative potential on the two lines a3, a4. Control of the group station is obtained by additionally closing switch y which energises a relay U at the group station and disconnects electromagnet PW from time switch z and connects it to line a5, whereupon the switch t may be operated to step the programme selector P until the desired condition is established as indicated by the relays P1, P2, N1, and N2. To return the group station to its normal programme the switch y is released after sufficient operations of t to bring the selector P into its position corresponding to the instant of reconnection. The line a2 may be utilised to listen to operation of the group station selector by means of contacts i operated thereby to apply alternating current via condensers C1 and C2 to a telephone receiver T. A relay R operates at the group station in the event of a fault and its contact r energises relay St over line a1 to sound an alarm at the central station Z. Signalling apparatus S may also be associated with road-pads K.

Title: Improvements relating to automatic winding and checking devices
IPC: B66D5/34
Filed: 1920-09-28
Abstract: 169,625. Blockx, R. Sept. 28, 1920. Self-sustaining gear.-Comprises a construction of self-sustaining and braked lowering-gear of the type in which two eccentric members, disposed round a shaft, are adapted to be jammed inside a ratchet ring during hoisting and released to any desired extent when the controlling-handle is moved positively in the lowering direction. In the present construction the eccentric members are formed as hubs mounted side by side on the same shaft within a common ratchet ring, the hubs being jammed when eccentric to one another and free when concentric. In the illustrated form the hand chain-wheel 2 rotates the shaft 1 in the direction for hoisting, until the pin 9 thereon is moved from end to end of a slot in the driven pinion 8. This provides sufficient lost motion for the one eccentric hub 6 of a member fixed on the shaft, to be jammed in the selfsustaining ratchet-ring 7. This movement also jams the other eccentric hub 14 of the driven pinion in the ring 7 to aid in transmitting the drive. On the hoisting effort ceasing, the ratchetwheel is held by a pawl in the usual manner, the parts remaining in the jammed position. To lower, the hand chain-wheel is reversed so as to bring the pin 9 back to its original position in the slot, thus disengaging both hubs sufficiently to permit slip. Overrunning of the load during this operation causes the pin to re-traverse the slot and re-lock the eccentric mechanism. In cases where a non-rotating shaft 1 is employed, the eccentric hub 6 would be connected directly to the hand chain-wheel and have a pin-and-slot connection with the pinion 8. Specification 169,626 is referred to.
