Title: Improvements relating to gramophones having record changing mechanism
IPC: G11B17/02
Filed: 1950-01-17
Abstract: 682,092. Automatic gramophones. FORTUNE, H. J., and GARRARD ENGINEERING & MANUFACTURING CO., Ltd. Dec. 11, 1950 [Jan. 17, 1950], No. 642/50. Class 40, (ii). A marginal record supporting platform 16, Fig. 1 is movable from one position for supporting 12" records to another for 10" records, and when in the latter position, a platform 32 may be swung about a pivot 33 for supporting 7" records. The platform 16 is pivotally mounted at 17, Fig. 2, in a support which has a spindle 7 pivotally mounted in slots 8 in a bracket on the motor board. To move the support from the 12" to the 10" position, a selecting lever 10, connected to a pick-up selector arm of the kind described in Specification 632,828, is moved manually by a knob at its upper end to cause it to rotate about a pivot 11 and causes a cam 9 on the lever to move the spindle 7 across the slots 8. The lever is held in position by a roller 12 engaging a spring urged index arm 13. The support is returned by a spring 14. The cam has a concentric part 15 to allow the lever 10 to move into the 7" position, without moving the spindle 7. As the support moves, a bell crank lever 18, 19 having a slot 22 to take the spindle 7 causes the platform 16, to move its record supporting part to the correct level. At its forward end the platform is slotted at 23, Fig. 1, for a feeding tooth 24 on a plate which is pivoted to the top of a lever 26, Fig. 2, pivoted on the spindle 7. The feeding tooth is actuated through the lever 26 by a cam-operated by a control element as described in Specifications 606,458 and 632,828. When the 7" platform 32 is in use a hole 36, Fig. 1, in its feeding tooth 35 engages the main feed tooth 24. A pivoted steadying arm 30a with cushions 31 is provided for 10" and 12" records. The platform 32 overlies the arm 30a and if the platform 16 is moved from the 10" to the 12" position, the arm 30a lifts the platform 32 to disengage the tooth 24 from the tooth 35. The gramophone may be provided with a supporting device such as that described in Specification 676,021 for large centre hole 7" records.

Title: Improvements in or relating to means for protection against overloads, short-circuits, and backfirings in mercury vapour rectifiers
IPC: H02H7/127
Filed: 1934-01-08
Abstract: 416,822. Converting. AKT.-GES., BROWN, BOVERI, ET CIE, Baden, Switzerland. Jan. 8, 1934, No. 690. Convention date, Jan. 7, 1933. [Class 38 (ii).] A grid controlled rectifier is protected against overload, short circuit or back-ignition by means of a grid controlled valve which becomes conductive to apply a negative bias to the grids of the rectifier upon the occurrence of an overload &c. The valve 7, which controls the application of negative bias 6 to grids of the rectifier 4, has applied to its grid a potential consisting of a negative D.C. bias upon which is superimposed an A.C. potential proportional to the current flowing in the A.C. circuit. During normal operation the maximum amplitude of this A.C. potential is less than the D.C. bias so that the grid of valve 7 remains negative. When overload &c. occurs the amplitude of the A.C. potential becomes sufficiently large to cause the valve 7 to become conductive and apply a negative bias to the grids of the device 4. If the valve 7 is vapour or gas filled it will be necessary to break its anodes circuit to effect removal of the negative bias. This may be done automatically when the circuit breakers 1, 3 open. Specification 401,894 is referred to.
Patent GB-1465470-A (GB)
Title: Music teaching aids
IPC: G09B15/00
Filed: 1974-05-06
Abstract: 1465470 Music teaching aids J B COLESHAW W R C DAWSON and E L JONES 6 May 1974 [7 Feb 1973(2)] 58920/72 and 768/73 Heading G5X A music teaching aid comprises means for producing an electrical reference signal indicative of the pitch of a reference note, means for producing an electrical pupil signal indicative of a note produced by a pupil, means for comparing the two signals and producing an output which denotes if the pitch ratio of the two notes lies within a predetermined range of pitch tolerance or not, and a visual indicator controlled by said output. The means for comparing may include timing and frequency comparison. As described a pupil note derived from an electrical keyboard unit (A, Fig. 1, not shown), is converted to a signal P of the same frequency and input to a corresponding circuit 51a of the comparator 12. The number of P oscillations in a test period T is registered by a counter 49a, T itself being the time for m oscillations of the reference electrical signal Q selected by switch 13 from alternative sources such as another electrical keyboard instrument. Suitable gating arrangements to the latch 50a ensure that the pupil lamp (21a) operates if either the pupil note pitch or timing is outside specified limits. A further lamp 74a may be incorporated in the comparator 12. Pitch errors.-Master counter 40 counts m + 2 oscillations of Q repetitively. After one oscillation a pulse is output along line 47 to reset pupil counter 49a which counts P signal oscillations to a maximum of m + 3. Counter 49a only gives an output when it registers outside the range mŒ2. Counter 40 outputs a pulse on line 48 after m+ 1 oscillations of signal Q and the lamp is thus operated at this time if 49a registers a count outside the allowed range. About 0À1 sec. delay before the lamp operation is introduced through unit 68a by the coincidence detector 44a. Timing errors.-Lack of simultaneity between P and Q signals results in zero output from detector 44a causing the inverter 67a to feed a signal to S of latch 50a, triggering the lamp circuit and also causing a longer delay of about 0À4 sec. in conjunction with unit 68a before the lamp 74a operates. A modification (not shown) suggests incorporating additional latches and lamps in each circuit 51a to indicate if a pupil's note is sharp or flat. In a further embodiment (Fig. 4, not shown) one cycle of the P signal is used to define time T in which oscillations of 90 times the Q frequency are counted. A modification (not shown) uses v cycles of P signal to define T in which time u times the frequency are counted. The pupil signals can be made audible through speaker 63, and if a pupil plays more than one note on a keyboard at a given time either the highest or lowest note can be arranged to function as the pupil note.

Title: Process of manufacturing phosphorus or oxygen compounds thereof and gaseous mixtures
IPC: C01B25/12
Filed: 1930-01-09
Abstract: Phosphorus or phosphoric acid, and a gaseous mixture containing nitrogen, hydrogen and, if desired, carbon monoxide are obtained by reducing tricalcium phosphate with carbonaceous materials and materials such as silica or alumina in a blast furnace with a blast rich in oxygen, removing the phosphorus or its compounds from the gaseous mixture obtained, and reacting the carbon monoxide with steam to obtain hydrogen and carbon dioxide, which latter, together with the impurities, is removed, the hydrogen then being combined synthetically, wholly or in part and in one or more successive operations, with one or more of the other constituents of the gas mixture.  The oxygen content of the blast can be adjusted to give a final mixture of nitrogen and hydrogen in the proportions for ammonia synthesis.  Part only of the carbon monoxide may be converted with steam, and a mixture obtained in which the volume of hydrogen equals twice that of the carbon monoxide plus three times that of the nitrogen, which mixture can be used in succession for the syntheses of methanol and ammonia.  The residual gases may be used again in a cycle. The conversion with steam and the previous separation of phosphorus may be effected under pressure.ALSO:A gaseous mixture containing nitrogen, hydrogen and carbon monoxide is obtained by reducing tricalcium phosphate with carbonaceous material, and materials such as silica or alumina in a blast furnace, with a blast rich in oxygen, removing the phosphorus or its compounds from the gaseous mixture obtained, and reacting the carbon monoxide with steam to obtain hydrogen and carbon dioxide, which latter, together with the impurities, is removed.  The oxygen content of the blast can be adjusted so that after conversion of part of the carbon monoxide with steam, a mixture is obtained in which the volume of hydrogen equals twice that of the carbon monoxide plus three times that of the nitrogen, which mixture can be used for the synthesis of methanol.
