Title: Improvements in electric organs and like musical instruments
IPC: G10H1/34
Filed: 1945-11-10
Abstract: 599,059. Electrical musical instruments. MORTON, R. Nov. 10, 1945, Nos. 30065/45 and 10292/46. [Class 88 (ii)] [Also in Group XXXVI] In a musical instrument in which notes are produced by alternating electric potentials whose amplitude is not controlled at the source the intensity of the notes produced is made dependent on the speed with which the keys are depressed, the variable electrical elements determining the said intensity being operated through impulse mechanism actuated by the keys. Each key 37 actuates a hammer 42 by an arrangement 41 similar to a grand piano action and the hammer strikes a pivoted lever 8 to throw it upwards against the pressure of a spring 23. This lever 8 forms the moving vane of a differential condenser whose fixed plates 2, 6 are held in a frame 18. The lever 8 rises to a point dependent on the force or speed with which the key is struck and the increased capacity between it and the plate 2 is connected to increase the amplitude of the output accordingly. If a key is held down, the lever 8 is held at the highest point of its resulting movement by engagement of a pawl 25 with a ratchet 29 which is tilted towards it as soon as the stop 36 is raised by the key 37. The plate 6 is electrically connected to a load matched with the amplifying means connected to plate 2 so that the effective loading on the generator, connected to lever 8, is maintained substantially constant. In a modification, Figs. 2, 6, 7 (not shown), differentially connected variable resistances are operated by the lever 8 in place of the condensers. The ratchet 29 may alternatively be operated electromagnetically by a contact actuated by the key and in this case a note may be sustained, following release of a key, by a pedaloperated contact connected in series with the key contacts.

Abstract: 251,888. Danger, H. [Firm of]. Aug. 1, 1925, [Convention date]. Bakers' ovens.-In a gas-heated bakers' oven the walls of the baking-chamber are formed by heating pipes of elongated cross-section arranged contiguously and fed with the heating gases. The pipes may be of serpentine shape, to form a number of superposed baking-chambers; as shown, the pipes a are of S-shape and flattened in cross-section, the central horizontal limbs separating the upper and lower baking-chambers. The lower end of each pipe is expanded to the form of a cylindrical tube c and abuts against a socket d of brick set in the insulating wall e of the oven and containing a burner g.

Title: Blast furnace stock level control
IPC: G05D9/12
Filed: 1960-09-01
Abstract: 894,352. Electric selective signalling systems. REPUBLIC STEEL CORPORATION. Sept. 1, 1960 [Sept. 1, 1959], No. 30144/60. Drawings to Specification. Class 40 (1). [Also in Group XX] The level of stock in a blast furnace is measured by directing a beam of radiant energy, e.g. gamma rays, through ports in the wall of the furnace at opposite ends of a diameter, a radiation detector located at the outer end of one of the ports controlling a relay to operate an indicator, e.g. a neon lamp. In the described embodiment, seven separate radiation sources and co-operating detectors are employed divided into two groups, one of which directs beams of radiation across the furnace at distances of 6, 8, 11, 14 feet from the bottom of the charging bell in one direction (N-S) and the other group directs beams across the furnace at distances of 7, 9¢., 12¢ feet from the bell in another direction (E-W). The detectors, e.g. one or more geiger tubes, have their outputs supplied to respective integrators in turn supplying Schmidt triggers, so that when the level of stock falls below a given level the average pulsing rate of the geiger tube associated with that level rises and the Schmidt trigger changes its state to operate a relay. The upper detectors of each group may operate a flashing light if the stock rises above the associated levels, and relays operated by the radiation detectors may control the output of a voltagedividing resistance chain supplying a recorder. A solenoid actuated from a control station may be provided at each detector location to expose the detector to a small amount of additional radiation from a source carried on the armature of the solenoid so as to provide a check on the operation of the system, for example by observing the reading of a voltmeter connected to the output of the integrator.

Abstract: 1319547 Cathode-ray tube circuits PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 24 June 1970 [27 June 1969] 30683/70 Heading H4T In an arrangement for correction of distortion in a colour television display by modifying the vertical and horizontal deflection fields, each half coil of a pair of scan coils is provided with a tap so that the current in an inner section (adjacent the window of the saddle coil) may be modified in accordance with the spot deflection. By this means it is stated that the varying angles effectively subtended by the coils at the axis reduce certain higher-order effects of astigmatism. As shown in Fig. 4a a modifying current i 2  is passed through the window section of the two coil halves, this current being generated by a control unit receiving the outputs of both line and field scan generators and producing a parabolic current waveform at line frequency with an amplitude increasing with frame deflection. Fig. 4b shows an arrangement in which variable impedances shunt the tapped window portions, these impedances being controlled by deflection signals to produce a like effect. The invention is described in connection with shadow-mask tubes using electrostatic convergence.
