A musical instrument of the type in which the sound is produced by singing or humming into it has one or more vibrator elements consisting of a material which is substantially unaffected by the humidity of the breath. Thin metal (e.g. tin or aluminium) foil, thin sheeting of polythene, rubber or latex and paper which is waxed or moisture or grease proofed are specified. A member made of fine wire gauze or perforated metal or rigid plastic may be placed next to the vibrator element to obtain the required tautness or assist in obtaining the desired sounds. Alternatively, the rigid member may be embedded in or covered with the material of the element. A horn or trumpet may be removably secured to the instrument.

Abstract: 324,868. Stephens, A. J., (Excelsiorwerk Metallwarenfabrik Akt.-Ges.). April 23, 1929. No Patent granted (Sealing fee not paid). Casings and frames; driving-arrangements. - In a construction to give a motor of small dimensions, for example a gramophone motor, the body which carries the bearings for the armature shaft is secured to the field magnets at one end only and has extensions passing between the pole shoes to the bearing, at the other end of the magnets. The bearing body is also made as a composite solid of revolution to ensure concentricity of the armature in the pole bore after its withdrawal and reassembly. Figs. 3 and 4 are respectively plan and crosssectional views on the line A, A of a machine in which the bearing body d is shown separately in longitudinal section in Fig. 5. The body d is cylindrical and is secured to the magnets a by bolts v and a flange c at one end, at which end is one of the bearings f in the form of a circular plate held in the mouth of the body d by screws. The second bearing e is formed integrally at the other end of the body, the two end portions of which are united by connecting-bars o passing between the pole shoes. A conical extension piece k, secured on the member d by a clamping screw r or other means, terminates in a support l for a centre-point to take the end thrust of the armature shaft. This sleeve k is slotted at n so that the worm wheel or other transmission member can mesh with a corresponding member on the shaft. Slots p in the body d accommodate the brush-holders q.

Title: Process and apparatus for the purification of sulphur
IPC: C01B17/02
Filed: 1937-05-04
Abstract: <PICT:0478230/III/1> <PICT:0478230/III/2> Sulphur is purified by subjecting it in the molten state to a high voltage unidirectional electrical field whereby suspended impurities collect near the surface of one electrode and the part of the sulphur containing the impurities is removed.  The sulphur is preferably passed through a tank 1 having the cross-section shown in Fig. 2 and maintained at a suitable temperature, preferably that giving minimum viscosity of the sulphur e.g. about 150 DEG  C., by steam coils 7.  A plate 11 forms the collecting electrode and the other electrodes consist of a series of wires 5 arranged on frames 4 and suspended from insulators 6.  The tank is preferably divided by a plate 12 having an opening 13, and the upper frames 4 of the electrode are preferably level with the surfaces of the bath.  The impurities collected on electrode 11 fall into the trough at the bottom of the tank and are periodically removed through ports 14, which are heated to maintain the sulphur liquid.  The impure sulphur is fed in through opening 8, being deflected below the level of the molten sulphur by baffle 16, and pure sulphur leaves by pipe 9. For example, the electrodes may be spaced 6 inches apart and a voltage drop of 60,000 volts maintained between them.

Abstract: 1327569 Stamping L SCHULER GmbH 20 March 1972 [25 March 1971] 12923/72 Heading B3Q [Also in Division B5] The stopping distance a of a press ram 15, e.g. of a car body press, after application of a brake is sensed by a mechanical sensor 13 the movement of which is transmitted to elements for recording the stopping time. The sensor 13 may be mounted on a rack 7 meshing with a pinion 6 which drives a generator or alternator 5 connected to an electronic tune clock 21. A bracket 3 supports the device on a stand 1, 2 and is adjustable so that at position A of the ram, when the driving crankshaft is at 90 degrees from dead centre, a scale 8 on the rack is at zero with reference to the top of the bracket. Contacts 18, 19, which are closed, are connected in the emergency stopping circuit of the press. The sensor 13 is withdrawn and re-inserted during the next down stroke of the ram. An emergency stop is effected when the contacts 18, 19 are opened, the stopping distance a being measured at 8 and timed at 21. Instead of a rotary generator, an induction coil (22), Fig. 2 (not shown), may be used through which passes the sensor rod, part of which is non-magnetic. The stopping time may be read at the control desk of a press.

Title: Improvements in or relating to electrical installations for the regulation of physical magnitudes
IPC: G05B1/02
Filed: 1943-08-11
Abstract: 579,928. Electric control systems. LANDIS & GYR SOC. ANON. Aug. 11, 1943, No. 13003. Convention date, Aug. 13, 1942. [Class, 40 (i)] [Also in Groups XXXV and XXXVII] A physical magnitude such as temperature, fluid pressure, mechanical force, or moisture is automatically controlled in dependence on another magnitude by the aid of a Ferraris instrument responsive differentially to the two. magnitudes and co-operating with a periodically operating auxiliary member causing selective operation of contactors according to the sense of the differential response. The invention is described as applied to a system controlling the temperature of a building in accordance with the relation between the temperature outside and the temperature of a heating fluid. The disc 20 of the Ferraris instrument is driven by the voltage coil 1 and a coil 2 the current in which varies between positive and negative values according to the condition of balance of a Wheatstone bridge comprising resistance elements responsive to out-door temperature and to the temperature of the floor pipe of a heating boiler; this bridge may also include a resistance to modify the wiring for night conditions. The disc carries a pin 21 which is adapted, on displacement of the disc by unbalance, to engage a contact member 13 or 14 whereby its further movement is prevented. A roller 23 on an arm 22 carried by a slowly rotating shaft periodically engages the pin 21 whereby a circuit is closed at contact 13 or opened at contact 14 according to the position of pin 21. The circuit of a motor operating temperature regulating means, such as a boiler damper, includes the normally closed contacts 16 of a relay which is energized to stop the motor when contact is made at 13. The reiay circuit includes a maintaining contact 17 and the contact 14; when contact 14 is opened the relay is de-energized and the motor again operates. In a modification the coil 2 is in two opposed parts one of which is in series with a fixed resistance and the other in series with the temperature response resistances. The Specification as open to inspection under Sect. 91 describes also an arrangement, Fig. 4 (cancelled), in which pins 27 circumferentially arranged on a Ferraris disc 25 successively engage a leaf spring 26 carried by a weighted lever 28 and normally engaging an abutment 29 carried by the lever, so that in one direction of movement the spring is lifted from the abutment without moving the lever as each pin is driven past it but in the other direction the lever is actuated to lift the lever. The lever normally impinges upon a spring contact arm 32 to hold open a circuit which is closed when the lever is lifted. This subject matter does not appear in the Specification as accepted.
