Title: Improvements in and relating to electric luminous devices
IPC: H01J61/96
Filed: 1920-11-05
Abstract: 175,032. British Thomson - Houston Co., Ltd., (General Electric Co.). Nov. 5, 1920. Low-pressure metallic-vapour apparatus.-In a lamp or rectifier, a glow discharge takes place from a heated cathode in the vapour of an alkali metal at such a low pressure that it has a positive characteristic as distinguished from the negative characteristic of an arc discharge, i.e. below about 0.05 mm. of mercury and within a range of vapour pressure corresponding to temperatures between 200 and 300 C. Under these conditions it is stated that the cathode does not disintegrate at voltages of the order of 100 and currents of over 100 milliamperes, and the current remains constant throughout a considerable range of voltage. The ionized vapour neutralizes the space charge and thereby greatly increases the currentcarrying capacity of the lamp. In the apparatus shown in Fig. 2, applicable as a lamp or rectifier, the cathode 6 consists of a coiled filament of tungsten or other refractory material. The anode 9 also may be of tungsten. The envelope 5 is of a substance not acted on bv the filling-material, for example the refractory boro-silicate known as " Pyrex " glass. The envelope is thoroughly exhausted, during which process the glass is heated almost to its softening-point to remove water vapour. Preferably a small amount of sodium is introduced into the dried and exhausted bulb, and the bulb is heated to expel the sodium vapour. This process may be repeated. Finally a quantity of purified and redistilled sodium is introduced and allowed to remain in the bulb. The bulb may, if necessary during working, be heated or cooled externally to, maintain the temperature between 200 and 300 C. The cathode temperature should correspond to an efficiency of about one watt per candle. In the lamp shown in Fig. 1, a looped tungsten or other refractory filament 14 is supported by hooks 18 embedded in porcelain or glass buttons 16, 17 carried by a stem 15. The stem 15 and hooks 18 are of tungsten, nichrome, or other material more refractory than glass. The leading-in wires 19, 20 are of tungsten, molybdenum, &c. and extend from the seal to the opposite end of the framework. When operated on either direct or alternating current, a glow discharge takes place between portions of the filament at different notentials, and may emit several times the candle-power of the filament. The conductors adjacent to the leading- in conductors are of stout wire to avoid overheating. The envelope may be double-walled, the space between the walls being evacuated.

Abstract: 539,777. Cleansing metal articles ; recovering volatile liquids. ZUCKER, J. Dec. 4, 1939, No. 31442. [Classes 32 and 91] In apparatus for removing oil and grease from metal articles, of the type in which the articles are placed in containers which are moved by endless chains successively through chambers containing solvent and through a drying zone, a closable opening is provided for the introduction and removal of the containers, the arrangement being such that when the opening is opened the space behind it is shut off automatically from the chambers containing the solvent. In the apparatus shown the main casing 1 is provided with steam-heated compartments I, II, III containing the solvent above which are arranged lower cooling coils 4 and upper cooling coils 18, the latter carried by a plate 17. The containers 9 are in the form of open wire baskets each suspended from a rod 8, these rods being evenly spaced along and connecting endless conveyer chains 7 engaging sprocket wheels 6 of which the central pair is mounted on a shaft 10 driven from a motor M. The containers 9 are introduced and removed through an opening 12 fitted with a closure flap 11 pivoted along the lower edge of the opening and provided with an extension 11a which, when the flap is open, supports the adjacent container 9. A second flap 19 is operated from the flap 11 and, when the latter is opened, the two flaps serve in conjunction with the plate 17 to shut off the opening 12 from the space above the solvent. The flap 11 is opened, whereby the motor M is stopped automatically, when one of the containers 9 reaches the discharge position. The other containers are then stationary, one in each of the compartments I, II, III and one in the drying zone B where it is tilted by a roller 20 and caused to oscillate to facilitate the dripping off of the solvent. The motor M is started automatically by the closing of the flap 11. Alternatively the containers may be closed wire baskets each fitted with a toothed wheel engaging a rack to impart a rotary movement to the basket during its immersion in the solvent. Solvent condensed on the cooling coil 4 collects in a gutter 5 from which it may be removed or returned to the compartment III. Solvent vapours are removed by a suction fan V.

Title: Improvements in and relating to windows
IPC: E06B3/50
Filed: 1959-09-16
Abstract: 903,461. Windows. BIERLICH, J. H. Sept. 16, 1959 [Sept. 16, 1958], No. 31529/59. Class 20 (3). [Also in Group XXV] The sliding pivots 10, 11, Fig. 3, of a sash 2 sliding downwards in slideways 12, 13, Fig. 2, on the fixed frame 1 on opening the window about a horizontal axis parallel to the top rail, are locked in the closed position from turning about the horizontal axis while the sash can then be turned about pivots 25, 27, Fig. 2, and 30, Fig. 3, 58, Fig. 2, on a vertical axis intermediate the sides of the sash. The slideways 12, 13 have inverted L-grooves for the pivot pins 10, 11 and anticlockwise movement of the sash, as seen in Fig. 3, about the vertical axis from the closed position, is prevented by the end of a pin 23, Figs. 3 and 4, operated by the handle 9 and rack and pinion driven rod 45, 46, 33, Fig. 4, and an eccentric disc 34, projecting beyond a block 24 on the frame 1 and clockwise movement is prevented by the slideways 12, 13. The sash is retained in its open position when swung about its horizontal axis by braces 17, 16, Fig. 2, the lower ends of which pivot about pin 20 on the brace 17 and pin 19 on the main frame side member which pins are located in notches 37 at the ends of corresponding horizontal grooves 21 in the frame member 22 and in the brace 16. The window is fastened as regards movement about a horizontal axis when in its open position about the vertical axis by an inclined part 32, Fig. 4, on the operating rod 33 passing through the pivot pin 30 to move the pin 30 into the bore 58, Fig. 2, in the main frame lower rail. Continued movement of the rod 33 releases the horizontal locking by pin 23 and enables a notch 39 on the rod 33 to ride on an arcuate rail 40 concentric with the pin 30, to effect horizontal locking. A weather frame, whole or in two hinged parts is provided with at least a sealing packing 47, Fig. 5, which is forced into the joints between the sash and frame. Two or more seals may be provided forming air pockets. As an alternative to the notches 37, a rod 50, Fig. 14, forming a parallelogram linkage with the brace operates a locking pawl 56 on rotation of the sash about its horizontal axis to co-operate with a notch in the member 22 to lock or release the brace from the main frame.

[Class 69 (ii).] The apparatus described in the parent Specification is provided with means for rendering the damping or retarding device ineffective except near the end of a delivery operation. In one form, a cock 111, Fig. 1, in a byepass 110 connecting the spaces on opposite sides of the piston 102, is operatively connected to a cock 112 in the supply pipe 1 ; lost motion is provided so that the cock 112 is closed after the cock 111. Fig. 2 shows another form with the parts in the positions occupied at the start of a delivery operation, a cock in the delivery pipe 134 being closed. Initiation of supply causes pressure increase in the delivery pipe, which acts through a piston 130 to cause a member 126 to disengage a catch 121 from a stop 122. A spring 120 then moves a lever 116 until the catch 121 engages a stop 127 on the member 126. The subsequent fall in pressure caused by opening the delivery pipe cock allows return of the member 126 and the catch 121 engages a stop 123. When the delivery cock is again throttled or temporarily closed, the pressure disengages the catch and allows the spring 120 to close the byepass cock 111.
