Title: Improvements in or relating to burners for lamps in which liquid fuel is employed
IPC: F23D3/00
Filed: 1925-06-23
Abstract: 239,490. Rostaing, P. Sept. 4, 1924, [Convention date]. Wick burners, flat-flame, flame regulating in.- The wicks of a multiple wick burner are raised and lowered simultaneously by rotating a spindle 9, Fig. 1, operating through pinion and rack gearing 8, 7 a plate 11 carrying flexible strips 12 formed with teeth 13. The wick-tubes 4 are slidable with considerable friction in the burner head 1 and are connected together near their upper ends by a plate 5 and near their lower ends by welding together tongue members 6 bent outwardly from the tubes. In the normal position of the wick-tubes the flexible strips 12 slide in grooves formed by raised parts 14 in the wicktubes and the teeth 13 engage with the wicks, but when the wick-tubes are in their uppermost position and the plate 11 is moved to its lowest position the members 6 allow the strips 12 to move inwardly, thereby disengaging the teeth 13 from the wicks and allowing the wicks to be slid out of the wick-tubes for replacement. The flame may also be varied by adjusting the height of the wick-tubes in respect to a ring 16 provided in the chimney 15. In another construction of burner shown in Fig. 8, the flexible strips 12 are carried by a plate 11<1> operated by a screw 17 which is rotated by a worm-wheel driven by an endless screw 19 on the spindle 9. The plate 11<1> is prevented from rotating by supports 20 secured to the burner head 1. The supports 20 are formed with projections 23 for limiting the movement of the plate 11<1>. Removal of the plate 11' is permitted on the supports being bent outwardly. The endless screw may alternatively be arranged to engage radial teeth 18' on the upper surface of the wheel 18.

Title: Improvements in the manufacture of photoelectric cells
IPC: H01J40/06
Filed: 1929-05-27
Abstract: 332,002. General Electric Co., Ltd., and Campbell, N. R. May 27, 1929. Vacuum tubes. - Photo-electric cathodes consisting of a thin film of caesium or rubidium on a support of another metal oxidized before the deposition of the caesium are sensitized, particularly to white light and to light at or beyond the red end of the spectrum, by a glow discharge through a rare gas. A silver support is oxidized and caesium is introduced in such quantities that there is more caesium than is required to form the compound Cs2O with the oxygen in the support. The cell is then baked to 200‹ C., some caesium appearing in the pumping tube, and helium is introduced at a pressure of 1 mm. and a glow discharge is passed. The helium may be left in the cell so that the sensitivitv of the cathode, liable to decrease during the early life of the cell, may be restored subsequently by a glow discharge or automatically if the cell operates with considerable ionization. The oxidized silver may be replaced by oxidized copper and the helium by argon or neon. Specifications 306,996 and 309,224 are referred to. The Provisional Specification describes also a sensitization process using a Townsend light-controlled discharge and using rare gas containing hydrogen, for example, helium purified by charcoal cooled in liquid air.

Abstract: 1,163,990. Control of motors. OWENSCORNING FIBERGLAS CORP. 10 April, 1967 [18 April, 1966], No. 16354/67. Heading H2J. [Also in Divisions D1 and G3] An electric motor control circuit as shown in Fig. 9 is used to control the feed roll motor and winding motor 18 of a glass filament packaging machine (see heading D1J). On momentary closure the starting switch 218 relays CR1 and M are operated to close their contacts CR1, and M2 respectively thus energizing the two motors. This also energizes the holding relay M-1. When the package is fully wound yardage counter 224 opens switch 220 thus de-energizing the two motors via their relays M and CR1; relay contact CR1-CR3 is also closed to operate the motor brakes 132 and 158. As the size of the wound package increases the increasing number of windings cause the speed of the winding motor 18 to be decreased by potentiometer 176. As the tension of the running glass filaments varies the speed of the winding motor 18 is increased or decreased to keep the tension at a constant value by potentiometer 178. The arm of this latter potentiometer is moved by a pivoting arm carrying a roller over which the glass filament pass (see also Fig. 4, not shown). The two potentiometers control the winding motor current in conjunction with thyratron 244. On breakage of a glass filament during winding a drop wire 108 falls to energize the relay CR2-and open contact CR2-1 thus deenergizing the two motors via relays CR1 and M.

Fluid in a return line 9 from a control valve, not shown, passes through an opening 7 obturated by a member 5 upstanding from a piston 1, the larger side of which is open via a pipe 11 to the fluid in the return line downstream of the opening, whilst the smaller side of the piston is connected to an accumulator 13, also supplied with fluid from the return line downstream of the pipe 11. Upon a surge occurring at the opening 7 the pressure in the pipe 11 rises quickly whilst the accumulator pressure increases slowly, so that the piston moves upwards to cause the member 5 to further obturate, the opening 7. The converse occurs when there is a pressure drop in the line 9. The ratio of the piston areas is such that in a steady state condition the piston is balanced, obturating the opening by a fixed amount.
