Title: Sound radiating apparatus and systems
IPC: H04R3/12
Filed: 1975-02-13
Abstract: 1456790 Column loudspeakers P H TAYLOR 13 Feb 1975 6217/75 Headings H4J and H4X A column sound radiator comprises an even number of sound radiator units A (Fig. 1) spaced apart by substantially equal intervals d along a substantially straight line defining the column, and an additional sound radiator unit C located at the centre of the line. Preferably two further sound radiator units E are located on the line at opposite ends of the column and are spaced a distance d/2 from the adjacent unit C. In a modification at least one of the sound radiator units (e.g. unit C, the two adjacent units A, the units E) is replaced by a group of two or more sound radiator units spaced along a straight line at right angles to the line of the column and disposed symmetrically. An input signal is fed in opposite phase to the equally spaced units A above and below unit C. This may be effected by a transformer 1, or alternatively by simply interconnecting the 180 degrees feed pair of wires in opposite polarity. The signals are fed to respective units A through alternators R 1 , R 2 , R 3 , R 4  so that the relative amplitudes of the sounds from the units A in each half of the column from the units nearest to the centre decrease progressively in each half of the column in the series of ratios 1, <SP>1</SP>/ 3 , <SP>1</SP>/ 5  ... etc. The 0 degrees phase signal is fed to a 90 degree wide band phase shifter 2. The + 90 degree phase shift output is fed through an amplifier 3 to central unit C to produce a signal output in positive phase quadrature with respect to units A in the lower half of the line and produces a sound output which is substantially #/2 greater than the excitation of either of the units A adjacent to it. The - 90 degree phase shift output from the phase shifter 2 is fed through an amplifier 4 to the end units E so that they operate at equal amplitudes at a value which will minimize any residual side lobes. The arrangement is such that sound is substantially equally distributed over the whole vertical quadrant beneath the normal plane through the centre of the column while radiation in the vertical quadrant above the normal plane is minimized. An another arrangement (Fig. 6) conventional loudspeaker units are in a vertical stack facing downwards. The spacing of the units is as shown in Fig. 1 and they are fastened together by rods 5. The backs of the units are closed to inhibit sound radiation upwards. A dummy cover 6 is fitted below the bottom units E. Amplitude and phase of radiated sound is as in Fig. 1. Such a stack centrally located over a listening area pro - vides the same sound coverage in all horizontal directions beneath the stack.

Title: Improvements in or relating to steam generators
IPC: F22G5/00
Filed: 1957-02-25
Abstract: 815,406. Forced-flow steam boilers. SIEMENS - SCHUCKERTWERKE A. G. Feb. 25, 1957 [Feb. 23, 1956], No. 6277/57. Classes 123(2) and 123(3) In a forced-flow, once-through steam generator operating at or above critical pressure and having first and second stage reheaters disposed in a hot flue gas zone, the reheaters are protected against overheating during the starting-up period by passing steam from the generator through the first stage reheater, separating water from the steam discharging from the reheater and passing the steam through the second stage reheater to the plant condenser. Under normal operating conditions, steam from the boiler 11 is superheated at 10 and flows via a stop valve 5 through the turbine stages 17 18, 19, between which it is reheated in reheaters I, II, the turbine exhaust passing to a condenser 16 from which condensate flows to a feedwater tank 15. During starting, the valve 5 is closed and the reheaters isolated from the turbine by closing valves 6...9. Steam flows directly from the superheater through a line containing a valve 1 set to maintain the maximum operating pressure in the superheater to and through the reheater I from which a steam-water mixture flows through a valve 2, set to maintain the maximum operating pressure in the reheater I, into a separator 12 in which a constant level of condensate 13 is maintained by a level regulator 14. The steam liberated in the separator flows through and cools the reheater II and passes therefrom through a spring-loaded valve 4, set to maintain a pressure of about 12 atm. in the reheater II, into the condenser 16. In a modified starting method the generator is started at minimum pressure by fully opening the valves 1, 2, the valves 5...9 being closed, the loading of the valve 4 determining the starting-up pressure. In both methods, when the superheated steam temperature is reached the valves 1, 2 are closed and the turbine started by opening valves 5...9.

Title: Improvements in means for mounting rotating bodies upon driving shafts
IPC: F16D3/76
Filed: 1930-02-27
Abstract: 334,160. Suhner, O. Feb. 27, 1929, [Convention date]. Universal joints.-A rotating body such as a grinding-wheel is mounted on a driving-shaft with the interposition of an indiarubber ring clamped between two pressure cones on the shaft and two clamping-flanges screwed together to establish driving-connection between the ring and body, the ring being free between cones and flanges to allow the rotating body to centre itself. The full width of the wheel is thereby used, vibration is reduced, and danger of the wheel flying off is eliminated. Between a grinding-disc 2 and shaft 1 is placed an indiarubber ring 6 clamped to the shaft by coned bushes 3, 4, abutting under pressure of a nut 16 against a shoulder 15 on the shaft. The disc is clamped to the ring by clamping-flanges 10, 11 having sleeves screwed together. A metallic sleeve 13 is interposed between the outer sleeve and the grinding-disc. The clamps have holes 14 for engagement with a key, and between the rotating clamp 11 and the disc is a loose bearing-member 12. The shaft 1 is connected to a flexible shaft passing through a handle part 17. According to a modification, the clamping-flanges are connected only by bolts which pass through semicylindrical recesses in the rubber and in a white metal sleeve between the rubber and disc, thereby acting as keys. The bolts are surrounded by bushes throughout their length to reduce friction when tightening, and the bolt-heads are covered bv annular ribs on the flanges. The bolts may pass through the rubber ring, and the bushes 3, 4 may have ribs to engage grooves in the rubber. The device may be applied to existing stationary grinding-plant, provided it is mounted on a rigid shaft and that the workpiece is pressed against the working disc and not vice-versa.

Title: Isonicotinic acid derivatives and process for the manufacture of same
IPC: C07D213/86
Filed: 1952-03-14
Abstract: The invention comprises 2-alkyl-, 2-alky-lidene-, 2-cycloalkyl-, 2-cycloalkylidene-, 2-furfuryl-, 2-furfurylidene-, 2-hydropyrimidyl-and 2 - hydropyridylidene - 1 - isonicotinylhydrazines, and the manufacture thereof by condensing isonicotinylhydrazine with a carbonyl compound of the formula R=O (where R represents an alkylidene, cycloalkylidene, furfurylidene or hydropyrimidylidene radical), and, if desired, hydrogenating the 1-isonicotinyl-2-R-hydrazine so formed.  The condensation is advantageously effected in the presence of a diluent (e.g. methanol, ethanol, or, when the compound R=O is a lower aliphatic ketone, excess of this substance), and the hydrogenation catalytically (e.g. in the presence of platinum black).  Examples describe the condensation of isonicotinylhydrazine with acetaldehyde, acetone, propionaldehyde, butyraldehyde, isobutyraldehyde, heptaldehyde, methyl hexyl ketone, hexaldehyde, cyclohexanone, furfural, alloxan and 2-ethylhexaldehyde, and the hydrogenation of the products except in the last four cases.  In a further example, condensation with cyclohexanone and hydrogenation are effected simultaneously.  The products are useful as chemotherapeutic agents, especially the field of tuberculosis.

Title: Improvements in and relating to electric motor control systems
IPC: H02P7/34
Filed: 1941-05-24
Abstract: 547,613. Electric motor control systems. BRITISH THOMSON-HOUSTON CO., Ltd. May 24, 1941, No. 6681. Convention date, May 25, 1940. [Class 38 (iii)] In a Ward-Leonard system for rolling mill drives, the field winding 12a of the generator 12 which supplies the motor armature 10 is energized by an armature reaction-excited dynamo 15. The latter has a control field winding 15c energized through forward or reverse contactors 18, 19 in response to movement of a washer controller 11 and is adapted to force the excitation of the generator 12. This forcing is opposed by a second control winding 15d on the exciter field energized by the voltage of the generator 12. This excitation of the latter is caused to build up rapidly to a value determined by the cutting out of resistances 20 from the circuit of the winding 15c by contactors 44 ... 46 under control of the master controller 11. The winding 15d also operates to reduce residual magnetism in the generator field to zero and thus prevents creeping of the motor when the controller is in the off position. A further winding 15h is provided on the exciter and operates to maintain excitation for a period after the master controller is returned to the off position so as to limit pump-back current. This winding is excited by the difference (when of appropriate polarity as determined by rectifiers 23-24) between the voltage across a potentiomer 27 and an amplifying generator 22 excited in accordance with the current in the commutating winding 12b of the generator 12. An anti-hunting winding 15g excited through a transformer 21 also is provided on the exciter 15 in addition to series and shunt windings 15e, 15f. The field winding 10a of the motor 10 is supplied from an armature reaction-excited dynamo 28 having an initial field control winding 28c in which regulation is effected by resistances 29 controlled by the master controller 11. The machine 28 has a second control winding 28f energized in accordance with the load on the motor 10 and operating to strengthen the field of latter and thus increase its torque under heavy load. The winding 28f is excited by the difference (when of appropriate polarity as determined by a rectifier 48) between the voltage across a potentiometer 43 and an amplifying generator 32 having a field winding 32a excited through forward and reverse contactors 34, 35 in accordance with the current in the commutating winding 10b of the motor 10. An additional winding 32b connected in parallel with the field winding 10a, of the motor is provided on the generator 32 to alter the calibration of the load current limiting means in accordance with the field setting of the motor 10 by the resistances 29. The machine 28 also has an anti-hunting winding 28e and series and shunt windings 28h and 28g.

Title: Improvements in or relating to electrical systems for converting direct current into alternating current
IPC: H02M7/62
Filed: 1942-05-20
Abstract: 553,227. Converting. STEVENS, A. H. (Electronic Laboratories, Inc.). May 20, 1942, No. 6874. [Class 38 (ii)] In a system for converting D.C. from a source 19, 20 into A.C. in a load circuit 18 by means of a self-interrupter 21 with opposed contacts 22, 23 through which the source 19, 20 is alternately connected to the two halves of a centrallytapped primary of a transformer 10, the secondary of which supplies the load current, a capacitor 28 is connected across the contacts 22, 23 and the transformer core has an air gap 53, the arrangement being such as to prevent sparking at the contacts 22, 23. The capacitance 28 is charged one way when the contact 21 engages the contact 22 and the opposite way when the contact 23 is engaged. The condition for no sparking at 22, 23 is that the capacitance circuit should have such a period of oscillation that the capacitor changes from maximum charge one way to maximum charge the other way while the contact 21 is moving from one contact to the other. This is achieved by suitable choice of values of inductance and capacity for the circuit. The air gap in the transformer core ensures that the magnetizing current varies substantially linearly with respect to the voltage.
