Title: Improvements in or relating to organs, harmoniums and like musical instruments
IPC: G10B1/00
Filed: 1927-12-23
Abstract: 307,142. Schirm, E. Dec. 23, 1927. Drawings to Specification. Pipe and reed organs; stop and coupler actions. -For the synthetic production of various tone qualities by sounding together as one note pipes or reeds of harmonically related pitch, these are so voiced as to be as free as possible from overtones. Thus flue pipes or spherical resonators may be used on low pressure wind; or reeds may be provided with resonators. The separate registers in such instruments thus differ only in intensity and pitch, the pipes in each register being tuned in equal temperament, while the pitch relations between the registers may be the just intervals, especially the natural thirds, or the tempered intervals. The number of pipes may be further reduced by enclosing individual ranks or groups of ranks in separate swell-boxes, and also by the adoption of the extension system. The synthetic tones thus produced may however be used in conjunction with those of pipes or reeds of ordinary voicing. The system may also be applied to ranks of pipes of which the tone changes from one part to another, as described in Specification 218,252. An action is described and illustrated in which a wind chest has two sets of ducts at right angles, one set connected to the key-valves and the other set connected to the pipe-valves, the ducts being connected by apertures controlled by diagonally-arranged stop-slides so that pipes of harmonically related pitch in each rank may be sounded together in various combinations; the apertures are provided with non-return valves.

Title: Improvements in speed governors for power engines
IPC: G05D13/00
Filed: 1936-12-23
Abstract: 483,863. Fluid-pressure servomotorcontrol systems. FAGELUND, R. Dec. 23, 1936, No. 35267. [Class 135] A fluid-pressureactuated piston 13 for adjusting the throttle valve 3 of an engine is acted upon by pressure fluid, for example steam, through ports 16 and 21 under control of a slide valve (not shown), operated by a governor of the type described for example in Specification 273,927, [Class 57], to actuate the valve 3 through a rod 6 which is connected at 15 to the piston rod 14. Whilst the fluid pressure acts on the full area of the piston 13 to move the throttle valve 3 in the opening direction, the closing movement is effected by the pressure fluid acting upon the annular area 22 so that the closing force is not as great as the opening force. An auxiliary valve member 23 moves with the piston 13 under the action of a spring 29 to close the passages 18 for the admission of pressure fluid to the top side of the piston 13 when the piston has made only part of its stroke, the remaining portion of the stroke being effected by the expansion of the pressure fluid so that the opening movement is effected with gradually decreasing power to prevent shock. The closing movement may also operate in a similar way by providing a pressure-communicating port 33 to the lower side of the piston controlled by a groove 32 in the rod 14 so that the pressure-fluid supply is cut off after a short closing movement, the remaining movement being effected by expansion. The closing movement may be effected by a spring instead of fluid pressure.

Title: Improvements in and relating to atomic spectral lamps
IPC: H01J61/09
Filed: 1960-10-14
Abstract: 896,744. Glow discharge lamps. COMMONWEALTH SCIENTIFIC INDUSTRIAL RESEARCH ORGANIZATION. Oct. 14, 1960 [Oct. 19, 1959], No. 35362/60. Class 39(1). A sealed-off discharge tube comprises a transparent envelope containing at least two hollow electrodes 5, 6 each of which is adapted to function as a cathode capable of providing an atomic spectral light source. The materials of the electrodes are such that no two electrodes provide the same spectrum and the electrodes are arranged so that light from any of the electrodes can be viewed without obstruction by any of the others. For example, seven hollow electrodes may be arranged side by side so that their interiors may be viewed from one end of the envelope, Fig. 3 (not shown). As shown, tungsten or chrome-iron lead wires 7 support two hollow electrodes which may be of Ag, Al, Au, Bi, C, Ca, Cd, Cr, Cu, Fe, Hf, Ir, Mg, Mu, Na, Ni, Pb, Pt, Sb, Ti, V, Zn or Zr. Metals of low mechanical strength such as Pb, Cd, Sb or Bi, may be melted into the bottom of a hollow aluminium cathode or provided as a liner therein. Cathodes of an easily oxidizable metal, e.g. Ca, may be machined under oil. Highly reactive metals, e.g. Na, may be used in the form of a salt in an aluminium or graphite cathode. One electrode may be made of an alloy of various metals, e.g. brass, or of sections of different metals. The envelope 4 may be of C9 or W11 glass with a window 11 of Corning 9741 glass or fused silica, and preferably has an internal volume of at least 150 cm<SP>3</SP>. The tube may be operated with an A.C. or D.C. source of several hundred volts connected across two electrodes. During manufacture of the tube, the envelope is evacuated and internally "torched" with a gas flame several times before being filled with neon at a pressure which is increased until the luminous region of the discharge is confined to the interior of the negative electrode, i.e. about 2 mm. of Hg. The discharge is operated for a period at the highest current which is possible without melting the cathode and then rapidly evacuated, whereupon profuse sputtering occurs, which cleans the cathode surface. This process is repeated about six times after which the anode is conditioned similarly by reversing the potentials. The tube is finally filled with neon at about 2 mm. of Hg. Alternatively, to obtain a longer tubelife, the tube is filled with argon.

Abstract: 574,086. Signalling by visible signals. BRITISH THOMSON-HOUSTON CO., Ltd., and LUCAS, G. S. C. Dec. 6, 1938, No. 35585. [Class 118 (ii)] [Also in Group XX] A device for operating the shutter of a signalling lamp comprises means for producing compression and rarefaction in a stream of air, and a valve for applying the compression or rarefaction alternately to opposite sides of the shutter mechanism. The lamp 1, Fig. 1, preferably an electric discharge lamp, is housed in a cylindrical casing 4 and is surrounded by coaxial cylindrical glass walls 6, 9. A shutter member 13 slides-in the space between the lamp and the cylinder 6, while another member 13<1> slides in the space between the cylinders 6, 9. Flanged sleeves 14 limit the movement of the shutter members which is produced by means of a flow of air in conduits 16, 17 in the cylindrical casing 4. The conduits terminate on opposite sides of a cylindrical valve chest 18, Fig. 2, connected at its opposite ends to outlet and inlet conduits 20, 21, respectively, in which a flow of air is produced by a centrifugal fan 22 driven by a motor 23. A butterfly valve 19a is fitted in the valve chest 18, and oscillation of the valve reverses the flow of air in the conduits 16, 17 and thus operates the shutter members. The valve may be operated by hand or by a solenoid 25. In another construction, a single shutter member is used. According to the Provisional Specification, the device may be used to operate the shutter of a cinematograph projector, or to oscillate a polarising screen for stereoscopic projection.

Title: Electrical systems for the automatic control of speed
Inventor: BANCROFT NORMAN ROY
IPC: H02P29/00
Filed: 1959-10-21
Abstract: 929,622. Automatic speed control systems. PYE Ltd. Oct. 18, 1960 [Oct. 21, 1959 ; June 13, 1960], Nos. 35685/59 and 20674/60. Class 38 (4). The cutting-speed of a lathe is maintained constant by coupling potentiometer P3 with the cross-slide, this potentiometer being connected in a bridge circuit comprising resistors R2, R3. The output of the bridge controls pentode V4 in series with the control windings of transductors 10, 11. As the potentiometer P3 is moved away from a null position, the control current for the transductors is increased to increase the output voltage from transformer T3. This voltage is rectified in voltage doubler circuit 12 and applied across resistor R4 in the grid circuit of thyratrons V1, V2. The headstock is driven through an induction coupling having coil 2 in circuit with the thyratrons, a tachometer generator 3 being also driven by the output shaft of the coupling. Thus, as the tool-rest is moved towards the centre, the spindle speed rises to conform with the decreasing radius of the workpiece, thereby maintaining the cutting- speed constant. A D.C. bias winding for each transductor is energized through resistor R5 which is adjusted to position the control working point at the required level and to allow compensation for tolerances in the transductors and valve V4. A potentiometer P1 is provided for manual speed control whilst potentiometer P2 can be set to provide a predetermined speed of the headstock, these potentiometers being connectible to the grids of thyratrons V1, V2, through a selector switch. The potentiometer P3 may be wound in a non-linear manner. In another arrangement, the output of the potentiometer P3 is an alternating voltage applied to the input of a transistor amplifier incorporating negative feedback and whose output is rectified to produce a variable D.C. bias to control the excitation of the coupling. The input signal to the amplifier may be adjusted in accordance with the gear ratio of the drive for the headstock.
