Title: Improvements in the manufacture of certain naphthylamine sulphonic acids
Filed: 1920-05-25
Abstract: 1 :4 :8-Naphthylamine disulphonic acid is separated from the isomeric acids, principally the 1 :3 :8-acid, which accompany its production, by taking advantage of the relative insolubility of the normal barium salt in hot water.  The 1 :3 :8-acid is then separated from the remaining acids by taking advantage of the sparing solubility in hot water of its acid barium salt. According to the process, a solution of a barium salt is added to a concentrated solution of the crude disodium salts of the acids resulting from the process of preparation described in Specification 4625/88, or a solution of the acids themselves is boiled with barium carbonate, oxide or hydroxide, whereby the normal barium salt of the 1 :4 :8-acid is precipitated. The filtrate is acidified, when the acid barium salt of the 1 :3 :8-acid is thrown down.  The resulting barium salts can be converted into other salts by double decomposition.  A preliminary purification of the solution of the crude disodium salts may be effected by adding acid to precipitate the acid sodium salts and then neutralizing these before treatment with the barium salt; or the acid sodium salts may be suspended in water, acid then added, and the solution boiled with barium carbonate for the separation treatment.  The process may be applied to the purification of individual salts of the 1 :4 :8- and 1 :3 :8-acids.

Title: Improvements in or relating to devices for ascertaining the energy delivered or absorbed by a piston engine
IPC: F02B77/08
Filed: 1941-11-05
Abstract: 550,294. Indicating work per stroke of piston engines. PHILIPS LAMPS, Ltd. (Naamlooze Vennootschap Philips' Gloeilampenfabrieken). Nov. 5, 1941, No. 14295. [Class 40 (i)] In a device for indicating the work done by an engine piston at each stroke, a condenser 11 is intermittently charged over a commutator disc 3 driven by the engine, the spacing of the contacts corresponding to equal distances of piston travel and the charging circuit including a valve 9 the impedance of which is varied in accordance with the momentary pressure in the cylinder with the aid of a pressure-sensitive condenser element 7 in the cylinder and an oscillator-rectifier unit 8. The voltage of the condenser 11 is applied to the horizontal deflecting electrodes 24 of a cathode-ray tube. At each end of the stroke, an impulse is given from a second commutator 43 to a generator 45, which thereupon applies a high-frequency voltage to the vertical deflecting plates 48, and shortly afterwards an impulse is given by a third commutator disc 41 to a gas-filled tube 18 to enable the condenser to discharge. By this means a trace such as that illustrated is given, the distances of the vertical marks 52 and 50 from O being proportional to the work done on and by the piston in the working and exhaust strokes respectively. As the speed increases, the readings for a given work per stroke decrease. To make the readings independent of speed, the impedance of 9 may be controlled additionally by a voltage proportional to the speed from an A.C. generator driven by the engine, or the commutator may have tapered segments, the brush being moved towards the wider parts as the speed increases. Power may be indicated by applying a voltage proportional to the speed to two grids of 9. Instead of mechanical commutators, apertured discs cooperating with photo-electric cells may be used. As a supplement to the cathode-ray tube, a voltmeter may be used associated with the condenser via a commutator so that the voltage due to the exhaust stroke is subtracted from that due to the working stroke.

Title: Improvements in superheterodyne radio receivers
IPC: H03D7/06
Filed: 1939-05-15
Abstract: 523,883. Superheterodyne circuits for wireless reception. PHILIPS LAMPS, Ltd. May 15, 1939, No. 14492. Convention date, May 17, 1938. [Class 40 (v)] In a mixing valve circuit negative feedback is applied to the signal input by a cathode load, but not to the oscillator circuit this being connected across grid and cathode, thus avoiding undesired couplings between the oscillator and receiving circuits. In Fig. 1, the cathode load 18 applies the whole of the signal voltage developed across it to the input grid circuit 3 through the condenser 20, the D.C. bias being applied through a high resistance 19 from a tapping on resistance 18. The output 22 of a local oscillator 21 is connected across the oscillator grid 5 and the cathode 2 and is self biasing through condenser 23 and resistance 24, thus avoiding any negative feedback to this circuit. In a modification Fig. 2 (not shown) a triode-hexode valve is used as oscillator and mixer. The cathode load is not limited to a resistance but may be a damped tuned circuit or a circuit sharply tuned to any unwanted frequency, for example a frequency, such as four times the intermediate frequency or the intermediate frequency which produces a heterodyne whistle.

Title: Improvements in or relating to combination locks for doors or the like
IPC: E05B37/12
Filed: 1930-05-12
Abstract: 355,280. Permutation locks. BISHOP, F. C., 8, Lyons Range, Calcutta, India. May 12, 1930, No. 14583. [Class 44.] Sliding bolts.-A permutation lock comprises a number of discs 3 each rotatably mounted on a sleeve 8 adapted to be rotated by a spindle 4 through a pin and slot connection 5. Each sleeve carries a wheel 10 provided with a pin 11 which passes through one of a series of holes 12 in the discs and engages one of a number of recesses 14 in the wall 2 of the casing 1. The wheel 10 is pressed towards the discs 3 by a spring 7. The spindles 4 have plates 6 to enable the discs to be set to starting position. When the spindles are turned to operate the discs 3 to bring the notches 18 therein into opening position, the pins 11 move over the recesses 14 against the pressure of the springs 7, thus enabling the lock to be operated in the dark by the sense of touch. To free the discs 3 for changing the combination, the sleeves 8 are pushed in against the spring 7 to disengage the pins 11 from the discs. The discs engage in recesses 27 in a jamb plate 20 formed between a flange 21 and projections 26, so that when all the notches 18 register with these recesses, the door can be opened. A bent portion 24 of the front of the casing 1 engages an inclined surface on the plate 20 and masks the discs. To enable the door to be opened without operating the combination, the edge plate 30 of the lock is provided with a bevel 33 engaging a bevel 37 on a floating plate 39, which engages a bevel 32 on an extension of the lock plate 2a. The plate 39 has a series of notches 40 arranged to be entered by the edges of the wheels 3 to lock the plates 39. Bevels 43, 44 on the plate 39 are adapted to engage bevels 45, 46 on a fixed jamb plate 47. The plate 39 has a slot 52 opening into a channel 53 and housing a latch 54 on a spindle 55. When the spindle is turned to cause the latch to project out of the slot 52, it enters a recess in the plate 47, thus locking the plates 39, 47 together. The latch 54 may be locked in position by a sliding bolt 62 which enters a slot 64 in the latch.

Title: An improved closing means for electrical instrument cases

Filed: 1925-06-05
Abstract: 236,188. Soc. Genevoise d'Instruments de Physique. June 28, 1924, [Convention date]. Casings for meters and instruments.-In closures for electrical insbrument cases, and particularly for electricity meter casings, in which an angle plate g co-operates with a screw l to hold the cover b or one part of the case against the other part a, one branch f of the angle-plate is narrower than the other branch h and is inserted from the outside into the part which the angle-plate holds in place so that the screw l is as close as possible to the wall of the case. Distortion of the case by the screw is thus minimized so that part of the instrument mechanism may be mounted on a bracket on the part a. The change in width between the branches f, h is sharp and of equal amount on either side of the angle-plate, the two shoulders so formed bearing against the part b. The branch f is inserted through a rectangular slot in the part b adjacent a flange d on this part enclosing packing c. The pull of the screw is sufficient to keep the angle-plate in place, but the plate may be welded, riveted, or otherwise attached to the part b. The head of the screw may be flush with the part b. The screw engages a tapped hole in an angle-plate carried by the part a or in a U-shaped member k, one leg of which is shorter than the other and hooks under a rim e on the part a and the other leg of which presses against the angle-plate g and acts as a support about which the parts a, b are drawn together. The shorter leg is in line with the wall b.
