Title: Process for removing the residual gases from the metal casings of electric discharge tubes
IPC: H01J9/385
Filed: 1926-08-27
Abstract: 257,620. Siemens - Schuckertwerke Ges. Aug. 28, 1925, [Convention date]. Vacuum tubes.-Residual gas is removed from the metal casing of a discharge tube by surrounding the casing with a gas or liquid, such as an alkali metal, preferably sodium or potassium, which absorbs the residual gas more readily than does the casing. Diffusion of residual gas is increased by cooling the outer surface by circulation of the absorbent gas &c. The absorbent gas mav be maintained at a low pressure to prevent passage into the tube.

Title: Improvements in and relating to machines for delivering a certain weight of finely divided material
IPC: G01G13/18
Filed: 1949-08-16
Abstract: 668,202. Automatic feed weighers. VALLEY PRODUCTS (LYE), Ltd., and TEARNE, W. Aug. 15, 1950 [Aug. 16, 1949], No. 21277/49. Class 143. In an automatic feed weigher of the kind in which material is fed to a weight pan 5 down a vibrating trough 2, cut off is effected by immobilising the vibrator 1 and, simultaneously, closing the end of the trough with a pivoted gate 18. This gate is pivoted to a rigid bracket at 19 and, during feeding is held away from the trough, against the aciton of a spring 21, by an electromagnet 20 which is energised in series with the vibrator 1 when an abutment 12 is in contact with an arm 13 of a two-way switch 17. On the attainment of a predetermined weight of material in the pan 5, the beam 6 tilts and abutment 12 is disengaged from arm 13 so causing switch 17 to effect cut off and simultaneously, so energise a dumping solenoid 33. When energised this solenoid lifts a member 31 so tripping a latch 29 and allowing the flap 22 to open and deposit the charge in a shoot 34 which leads to a packing machine (not shown). After dumping, the flap 22 is automatically closed by a counterweight 24. A switch 27 in series with the vibrator 1 and magnet 20, and operated by the flap 22, is opened during dumping and so delays the restarting of the feed by switch 17, which is re-operated as soon as dumping commences until after the flap 22 has been closed. The beam 6 which has stops 9, 10 and a dashpot 11 to control its movements, has a counterbalance weight supporting cradle 8 and adjustable weights 43, 44 which compensate for the weight of material suspended at cut off. A normally closed manually operated switch is connected in series with the solenoid 33 and allows the discharge of the weigher to be non-automatically controlled by a packer. In a modification (not shown) a second two way switch is connected in series with the switch 17 and serves to connect a normally short circuited resistor in series with the vibrator so effecting a dribble feed from the trough.

Title: Improvements in the heat treatment of metal castings
Filed: 1925-08-27
Abstract: 239,218. Baron, H., (Will, E.). Aug. 27, 1925. Annealing.-Metal castings are self-tempered, immediately after discharging them from their moulds, by placing them in a heat-insulating packing of finely divided kiesulguhr or the like, to which a proportion of about 10 per cent of comminuted calcined alumina has been added. In carrying out the process in the apparatus shown in Fig. 1, the metal from a furnace a is led into moulds b carried by an endless band c, driven bv a motor M. The closed moulds b when in position over boxes d filled with the packing, are opened automatically or by hand, and the castings are discharged into the boxes d in which they cool slowly and are tempered or softened. The moulds b may be constructed as containers in which the castings are cooled slowly during their transport to another room where the actual tempering is to take place.

Abstract: 1291207 Identifying and recording defective yarns MONSANTO CO 19 April 1971 [13 Feb 1970] 21814/71 Headings D1F and DIM [Also in Division G4] Apparatus and method for identifying a defective yarn in a moving warp sheet composed of a plurality of yarns comprises two light sources 26, 30 adapted to produce a beam of light 27, 34 across the warp sheet in the plane of the sheet to impinge on respective photocells 28, 32, the beams 27, 34 being non- parallel and being placed along lines meeting at an acute angle outside the part of the plane occupied by the warp sheet. It is stated that the cells 28, 32 provide output pulses upon variations in the intensity of the light beams occurring owing to the passage of a break or a fluff ball in one of the yarns, a pulse from cell 28 causing enabling of a counter 46 to count pulses over a line 44 derived by an electromechanical transducer 40, 42, the frequency of which pulses being indicative of the linear speed of the warp sheet, and a pulse from cell 32 stopping this count. Since all the yarns travel a different distance between the lines 27, 34, the defective yarn may be identified by the count held in the counter 46. This count may be fed to a recorder 48 and to a control 50 adapted to move a thread repairing unit 52 across the warp sheet to the defective line to repair the defect automatically. In a modification. Fig. 3 (not shown) the warp is split into three warp levels by an apertured plate (54), (56), a detection system being associated with each level, in a further modification, Fig. 4 (not shown), only one source (26) and one cell (28) are used, the light beam being reflected back across the warp by a mirror (58), a bi-stable circuit being used such that a first signal from cell (28) starts the count and a second terminates it. In a third modification, Fig. 5 (not shown), light beams (34), (27) are parallel and an apertured plate (64), (66) placed skew to the direction of movement of the warp sheet is employed between the beams.

Abstract: 781,032. Glass-heating lehrs. BRITISH HARTFORD-FAIRMONT, Ltd., and LAWSON, A. July 28, 1955, No. 21883/55. Class 51 (2). A glass-heating lehr 1, through which glassware coated with ceramic decorative matter in a vaporizable vehicle, e.g. wax, is traversed on an openwork conveyer 3, is heated by upper and lower electric elements 13, and has a preheating zone in which heated air, driven through cooling tubes 22 by a fan, is supplied upwardly into the lehr through two series of slots 25 and 26, being exhausted through valve-controlled chimneys 27 and 29 respectively. The air from the slots 26 carries off vapours driven from the decorative matter initially, any residual carbon being burnt off by the air from the slots 25. The heating elements may be selectively and thermostatically controlled, or the lehr may be oil-fired or heated by gas-fired radiant tubes. In the firing zone, the lehr atmosphere is continuously circulated by fans 14 through ducts 15, down side ducts 16, and upwardly through the ware back to the fan inlets. Final cooling of the ware is by counter-current air supplied by a fan disposed near the outlet end of the lehr, Fig. 1 (not shown), this air being exhausted through a roof vent.

Class 38(3) [Also in Group XXX] The parent Specification is modified in that instead of satisfying the power requirements according to the formula given by using wound-secondary A.C. induction motors having differing numbers of poles, the number of poles in each motor is the same, but the running speeds of the motors are arranged to be different so that by choosing the correct gear ratio between each motor and its driving pulley in relation to the pulley diameter the pulleys receive power in the correct ratio. The modified formula deduced for the simple case shown in Fig. 2 of the drawing of the parent Specification is: where n<SP>5</SP> and n<SP>6</SP> are the speeds at which the motors respectively run, Á is the effective coefficient of friction between each pulley and the belt, and # is the angle of lap of the belt around each pulley (which is the same for both pulleys).
