Patent GB-1466117-A (GB)
Title: Electronic musical instrument with automatic bass accompaniment
IPC: G10H1/00
Filed: 1974-02-21
Abstract: The electronic musical instrument with keys, e.g. an organ, comprises an automatic bass accompaniment device (5-10), which is cut in by striking a key. The bass accompaniment device (5-10) has inputs (51-55) which are connected to the outputs of a reduction circuit arrangement (1-4). The 2<12>-1 combinations of the signals which are generated by striking the keys are applied to the inputs (11-14, 21-24, 31-34) of said reduction circuit arrangement. The input signal combinations are digitally processed in the reduction circuit arrangement (1-4), converted into 31 different basic chord signals and fed to the bass accompaniment device (5-10). The latter is further provided with inputs (71-73) for inputting signals which control the selection of the bass program stored in a bass program selection element (7), and with an input (61) for clock signals which are produced, e.g. by a rhythm generator. Some of the bass tone switches (9) which form the bass accompaniment device (5-10) are connected via inputs (91-96) to six tone sources, which generate tone signals in accordance with a whole tone scale. Depending on how it is controlled, the bass tone switch (9) connects these inputs (91-96) to the input (101) of an output stage (10) which, after a frequency division effected by appropriate control, passes on the tone signals originated by the tone sources to a sound reproducing device via their output (110). <IMAGE>

Title: Improvements in systems utilising dynamo electric machines for the remote transmission of angular motion and torque
IPC: G08C19/48
Filed: 1946-03-15
Abstract: 609,849. Electric-control systems. BRITISH THOMSON-HOUSTON CO., Ltd., CHOUDHURY, S. A., and CLARKE, L. J. March 15, 1946, No. 8161. [Class 40 (i)] An arrangement for a selsyn system comprises means responsive to currents or voltages in the circuits of, or connecting, the transmitter and receiver, to perform a protective function when a predetermined error voltage exists. In one embodiment, each of the connections a, b, c, Fig. 1, between the secondary windings 2, 4 of the transmitter and receiver respectively includes a relay 5, 6, 7 each having a break contact in series with a circuit breaker 8. Excessive current in any of the three leads causes operation of the circuit breaker, thereby interrupting the main supply. In place of current-operated relays, voltage operated relays may be connected across the leads a, b, c. In a case in which both the transmitter and receiver are driven by the apparatus to be controlled and the receiver has a cylindrical rotor, the winding 3, Fig. 2, on the receiver is connected to a relay 5. The current in this circuit increases with an increasing error voltage and, at a predetermined value, actuates the circuit breaker 8. Modifications of this arrangement, applied to the use of a receiver with a cylindrical rotor having windings in quadrature, Fig. 3 (not shown), and a salient pole rotor, Fig. 4 (not shown), are also described.

Title: Improvements in or relating to discharge nozzles of lubricating devices
IPC: F16N21/04

Abstract: 418,487. Discharge nozzles for lubricators. BRETTELL, F. G., 14, High Holborn, London.-(Lubrication Corporation ; 910, South Michigan Avenue, Chicago, U.S.A.) June 27, 1933, No. 8193/34. Divided out of 417,147. [Class 99 (i).] A lubricator discharge nozzle A having a lubricant conduit 24 is adapted to be connected at one end to a source of lubricant under pressure and is provided at the other end with a discharge orifice 45 which is brought into engagement with the spherical head of a nipple N on the part to be lubricated by a clamping member 37 having internal spherical coacting surfaces 44. The orifice and clamping member are relatively movable on an axis inclined to the axis of the conduit 24, preferably at an angle of 40‹, and the clamping member is so formed that the nipple N is introduced to the nozzle along an axis perpendicular to said conduit axis. The clamping member is screwthreaded to the nozzle A and is secured thereto by a set screw 38, and it is provided with a cylindrical aperture 41 as shown to receive the nipple and also an elongated opening 40 of width slightly greater than the diameter of the neck of the nipple, the surfaces 44 being formed on the inwardly extending portions between said aperture 41 and opening 40. The discharge orifice 45 is formed in a piston 43 which is disposed within the end of the nozzle and the clamping member and is subjected to the combined pressures of a spring 52 and the passing lubricant. The piston may be formed in two parts 47, 48 with an intermediate sealing ring 49, the part 47 being hardened.

Title: Improvements in or relating to sliding clasp fasteners
IPC: A44B19/28
Filed: 1953-03-25
Abstract: 736,622. Sliding-clasp fasteners. DESHAW, Z. Feb. 25, 1954 [March 25, 1953], No. 8319/53. Class 44. A slider for a sliding-clasp fastener comprises two opposed slider shields, joined to allow spreading apart for separating the stringers, one side of the slider having extended side walls which engage behind the fastener elements of one of the stringers and prevent separation of the slider from it when the shields are spread apart. The opposed shields 1 and 12 Fig. 3 are hinged about pins 20 in the slot 15 which are located in the bearing 6 in the rising portion 9. Shield 1 is U-shaped and the open ends form jaws 18 that are forced apart elastically, when the shields are pivoted apart, by the wedge 8 and produce a snap action. The open ends of pull tab 22 are bridged by pivot pin 24 located in the bearing 7 and have surfaces 25 substantially cylindrical with pin 24 as axis and ending in the radial recesses 26 (see Fig. 4). One or each wall of the bearings 6 and 7 are peened over the pivot pins. The position of the pivot bearings is such that the surfaces 25 normally engage the shoulders 19 of shield 12 and prevent the shields spreading apart. When the pull tab is rotated to position 221, Fig. 4, the shoulders 19 can enter the recesses 26 of surfaces 25 and the shields are free to spread apart. One stringer is retained in the slider by the extended side flanges 311 and 1411 and to prevent the ends of the shields nipping the stringers, either or both shields are levelled as at 50, Fig. 3. A recess 52 in the riser element 5 receives the stringer elements and reduces the overall width of the slider. Instead of being hinged together, the shields may be joined together by a spring opposing the spreading apart of the shields. The pull tab 22 has a triangular locking pin 25. Specification 736,327 is referred to.

Abstract: A liquid organosilicon copolymer containing 50 to 95 mol. per cent of the units <FORM:0688799/IV (a)/1> and 5 to 50 mol. per cent of the units <FORM:0688799/IV (a)/2> may be made by reacting a mixture of 50 to 95 mol. per cent of XCH2.Si.R2X and 5 to 50 mol. per cent of (XCH2)2SiRX, in which X is a halogen atom and each R is the same or different alkyl or monocyclic aryl radical, with an alkali metal, e.g. sodium, potassium, calcium, rubidium, lithium or sodium-potassium eutectic.  The reaction with the alkali metal, preferably in finely-divided form, is effected by contacting the alkali metal with the organosilicon mixture in the liquid phase. The reaction may be effected at room temperature or above and under reflux, the heat of reaction being dissipated by cooling of the refluxing solvent or by indirect heat exchange.  The alkali metal salt formed by the reaction may be removed by filtration and the filtrate distilled.  The resulting oily products have viscosities from 300 cs. to more than 15,000 cs., and find use as lubricants, hydraulic fluids, damping fluids, waterproofing liquids, electrical insulating liquids, and for prevention of foaming in aqueous and non-aqueous systems.  Examples are given in which X and R in the above formul  are chlorine and bromine and methyl and/or phenyl radicals respectively.  Specification 629,719, [Group IV(b)], is referred to.ALSO:A liquid organosilicon co-polymer containing 50 to 95 mol per cent of the units <FORM:0688799/III/1> and 5 to 50 mol per cent of the units <FORM:0688799/III/2> wherein each R is the same or different alkyl or monocyclic aryl radical and in which the units are bonded together by linkage of the free carbon bonds to the free silicon bonds of the units, (see Group IV(a)), may be used for the prevention of foaming in aqueous and non-aqueous systems.
