Inventor: GEORGE HENRI
IPC: H01J13/00
Filed: 1919-03-28
Abstract: 130,960. George, H. Aug. 8, 1918, [Convention date]. Metallic-vapour apparatus; arc lamps.-In a lamp containing inert gas at a high pressure of the order of atmospheric, the gas is driven by the mercury vapour, when the lamp is working, into a reservoir 8, the mercury having a continuous circulation from the anode chamber 3 through a tube 9 of at least 4 mm. internal diameter and the reservoir 8 back to the anode. On making the circuit, a tungsten wire 12 forming thei connexion to the anode heats the gas, causing mercury to be forced from the lighting tube 1 through a constriction 13 into a vessel 7 ; the arc is struck as soon as the meniscus is broken by the bridge of the tube 1. When the circuit is broken the mercury returns to the level 14. The vessels 7, 8 are mounted on a common tube 6 connected to the anode chamber 3. The wire 12 is enclosed within a tube 10 having an aperture 11. The gas may be nitrogen or argon, but is preferably neon at a pressure of about 70 cms. of mercury.
Patent GB-410299-A (GB)
Title: Improvements in gramophones and the like
IPC: G11B3/08
Filed: 1933-03-15
Abstract: 410,299. Gramophones. BLYTH, L. D., 5, Wellington Street, and JUBY, L. B., 6, Wellington Street, King's Lynn, Norfolk. March 15, 1933, No. 7904. [Class 40 (ii).] The tone-arm or pick-up arm of a gramophone is combined with actuating mechanism to form a self-contained attachment, the mechanism being driven frictionally by the turntable of the gramophone so that the tone-arm may be raised, traversed and lowered to repeat indefinitely any predetermined passage of the record, or may be returned to a predetermined starting position and the driving motor stopped. The tone-arm 13 is adjustably connected by a screw 32 to an arm 29 which is pivoted in a housing 12 mounted on ball bearings 11 and journalled in a cover 31 secured to the base 1. A friction disc 2, Fig. 1, adapted to engage the turntable 52, is mounted in arms 3, which are pivoted at 5, reduction gearing being provided to transmit motion from the turntable to a gear 9 having an eccentric inner wall 14 constituting a cam track to raise and lower the tone-arm by contact with a roller 30 on the arm 29. During playing, a pawl 17 retains the disc 2 out of action until a wedge-shaped projection 21 on the tone-arm housing engages an adjustable stop 19 and trips the pawl 17 thereby allowing the spring 20 to force the disc into engagement with the turntable thus initiating drive of the wheel 9 with consequent lifting of the reproducer from the record. At the end of this lifting movement, a stop 25<a> carried by the wheel 9 has advanced in an anti-clockwise direction into engagement with a spring-pressed stop 27 mounted on the tone-arm housing and rotates the housing to return the lifted tone-arm across the record until the projection 21 engages an adjustable stop 26 to arrest the housing, the spring stop 27 automatically disengaging from the stop 25<a> on continued rotation of the wheel 9. A leaf spring 25 carried by the stop 25<a> now wipes past a fixed stop 33 which flexes the spring until the end of the spring moves clear of the stop and returns to normal shape thus engaging a projection 15 on the arm 3 to move the disc 2 clear of the turntable and allow the pawl 17 to re-engage. The wheel 9 has meanwhile lowered the reproducer on to the record, thus commencing a fresh cycle of operations. A stop 24 on the wheel 9 may actuate two levers 24<a> which respectively switch off current to the driving motor and apply a brake to the disc 2. In a modification, the arm 3 is held by a pivoted adjustable stop 41, whose pointed end is moved by a stop 43 on the housing 12 to release the arm and allow the friction disc 2 to engage the turntable to initiate movement of the tonearm lifting cam. A spring-held stop 49 may be set to given position in a peripheral slot in the cover 31, this stop being engaged by a stop 48 on the housing 12 to arrest the traverse of the tone-arm at a predetermined position.

Filed: 1919-04-01
Abstract: 140,220. British Thomson - Houston Co., (General Electric Co.). April 1, 1919. Systems for continuous-current motors only.- The excitation of a traction motor 1, which runs regeneratively for braking, is made to vary inversely with the variations in speed, by means of a generator 4 the field 5 of which rotates with the main motor, its armature 6 being being independently driven. The field of the auxiliary machine consists of a main winding 14 connected between the line 12 and earth, and a winding 16 in series with the main machine; during motoring, these windings are additive, but when the machine 1 acts regeneratively, they are in opposition. A switch 18 is used to connect the armature 6 across the main field 3. With the main machine motoring, as its speed increases the speed of the armature 6 relative to its field 5 decreases, and consequently the added excitation of the main series field 3 decreases. Conversely. with the main machine working regeneratively, as its speed decreases the auxiliary machine generates at higher rate, and the excitation of the main field 3 is maintained.
