Patent GB-1461682-A (GB)
Title: Rhythm units for  musical instruments
IPC: G10H1/40
Filed: 1974-03-27
Abstract: 1461682 Rhythm generator NORLIN MUSIC Inc 27 March 1974 [17 Aug 1973] 13639/74 Heading G5J An electronic musical instrument has a rhythm generator 26 producing a plurality of different continuous series of discrete, non- overlapping pulses at times related to each other to form different rhythm patterns any one of which can be selected; a tone signal source (not shown) producing a plurality of tones one of which is selected, an amplitude modulator 16 to modulate the selected tone in response to some of the pulses from the rhythm generator, and a control connected to the rhythm generator, modulator and an output terminal to produce in response to certain pulses one output signal and in response to other such pulses another output, both outputs being from a plurality of output signals differing from each other in at least amplitude or wave shape. The result being a rhythmically modulated voiced tone signal. The rhythm generator may consist of a readonly memory with several outputs, one 30 being used to trigger a flip flop 32, the two states of which provide long and short decay times in the modulator 16. Flip flop 32 is reset at the end of the rhythmic cycle by line 34. Other pulses from rhythm generator 26 similarly control one flip flop which selects one of two tone colour filters and another flip flop which selects one of two maximum amplitude levels for the rhythmic sounds. The detailed circuitry is described with reference to Fig. 2 (not shown).

Title: Ventilating fans
IPC: F04D25/14
Filed: 1974-03-27
Abstract: 1471492 Axial-flow fans VENT-AXIA Ltd 21 March 1975 [27 March 1974] 13666/74 Heading F1C [Also in Division F4] An axial-flow ventilating fan has pivoted overlapping shutters 23 for closing an annular air channel 11, and shutter operating means responsive to impeller rotation for moving the shutters to an open position when the impeller is rotating, the operating means comprises bob-weights 29 which move outwards by centrifugal force forcing a cone 33 to engage a ball race 38B on a plate 34, which moves axially against the compression in a spring 28, thereby permitting shuttles 27 to move to the left under the action of springs 27A and rotate shutters 23 to their open position. Plate 34 is freed from shuttles 27 when the latter engage a stop 36, further outward movement of bob-weights 29 causing a vane plate 31 and a race 31b to move to the right against the actions of a spring 31a, the race 31b engaging ball race 38A on a cap 39 which forms the abutment for spring 28 the cap thus being disengaged from stop 36 thereby relieving the motor shaft 15 from the spring thrust. When the impeller slows down, the operating means acts in reverse to close the shutters. To ensure positive movement of the shutters, a toggle mechanism comprising a movable pivot 23b and a leaf-spring 14c is provided.

Title: A new or improved system of mural decoration
IPC: B05D5/06
Filed: 1922-05-16
Abstract: 198,887. Morrow, W. A. J. May 16, 1922. Ornamenting.-Relief effects are produced on walls by means of a paint thick enough to stand out on the wall and of such consistency that it will creep irregularly. The wall is rendered non- absorbent, and covered with a coat of white lead tinted light grey or dark grey, and a coat of white lead and zinc, or either separately, mixed with linseed oil, with or without varnish, and with any required pigment, but without turpentine. Just before this coat is dry, the relief paint is applied consisting of Paris white and oxide of zinc, mixed with strong glue and water to the consistency of putty, and then diluted with water to a workable ccnsistency, pigments being added. This paint is applied by means of a chamois-leather cushion or flap dabbed or flapped against the wall. After twenty four hours the surface is coated with transparent French polish, spotted with colour if desired, and coated with French polish and a mixture of Vandyke brown, varnish, and turpentine. A coat of dry colours and milk may be then applied, and when dry, removed to such an extent as will come off on a damp chamois leather. A final coat of French polish is then applied.

Filed: 1927-05-23
Abstract: 271,871. Aktiebolaget Elektrisk Malmletning. May 26, 1926, [Convention date]. Magnetic tests and measurements.-The position, configuration, and nature of ores, solutions of salts, &c. are determined by the disturbances they produce in a magnetic field, which is determined at various points in respect of strength and phase, the field or the potential or current induced thereby being compensated by means of an auxiliary field adjustable in respect of strength and phase. A primary field is generated by a loop 1 placed on the ground and carrying an alternating current. A search coil 9 is placed at various points to be examined and is connected m series with the secondary windings 7, 8 of two transformers and with an amplifier 10 connected to a telephone 11 or other indicator. The primary winding 2 of one transformer is connected, m series with an inductance 4 and in parallel with a resistance 5, across an alternating current source A, B such as a coil in which an alternating current is induced. The primary winding 3 of the second transformer is connected across the source A, B in series with a resistance 6. The secondary windings 7, 8 are rotatable with respect to their primary windings. The potential generated in the coil 9 is compensated by adjusting the secondary windings 7, 8 until no sound is heard in the receiver 11. From the adjustments of the windings 7, 8 the strength and phase of the magnetic field at the point at which the coil is situated may be determined. The amplifier 10, instead of being connected in series with the coil 9, may be connected in series with a second coil within this coil.
