Title: Improvements in or relating to electric discharge tubes provided with two or more electrodes
IPC: H01J19/28
Filed: 1923-04-25
Abstract: 205,784. Naamlooze Vennootschap Philips' Gloeilampenfabrieken. Oct. 21, 1922, [Convention date]. Vacuum tubes; R÷ntgen-ray tubes.-One or more electrodes of thermionic or other discharge tubes are supported by one or more sealed connecting- members of metal or alloy which adheres readily to glass and has a coefficient of expansion substantially the same as that of glass. The connecting-members consist preferably of chrome-iron in which the proportion of chromium depends on the nature of the glass and may vary between 10 and 50 per cent. For fusing into R÷ntgen-ray or potassiumsodium-glass an alloy containing about 17 to 20 per cent of chromium may be used. A small proportion of manganese or silicon may be added. A nickel-iron alloy with or without a thin plantinum layer is suitable for use with lead or R÷ntgen-ray glass, and molybdenum and tungsten for Pyrex glass. As shown in Fig. 1 a connecting-ring 6, carrying nickel or chrome-iron supports 5 for an anode 4, is fused to the end of a glass tube 2 sealed by a stem 7 projecting inwardly as shown or outwardly, and through which the anode leading-in wire 8 is sealed. A grid 11 is mounted in a similar way by means of a ring 9 fused into a glass tube 3 at the other end of the bulb. The filament supports 16 are welded or soldered to two discs 18, 19, Fig. 2 which are connected together by a thin glass layer and are fused at the outer edge to the tube 3. The discs are preferably surrounded by a thin glass layer before fusing into the tube. In another arrangement the discs are in the form of three segments or sectors; or a circular disc surrounded by an annular disc may be used, the discs being connected by an intermediate glass ring. Leading- in wires of nickel should be used for welding to discs of chrome-iron. In the arrangement shown in Fig. 4 the ring 42 supporting the anode 40 is fused to a glass tube 43 surrounding and fused to the tube 36 carrying the grid-supporting ring 37 and the supports for the filament. In another arrangement the anode and grid are each supported on a single tube by an are-shaped ring. In the arrangement shown in Fig. 10 the connecting-member for the anode 85 consists of a flat ring 83 the inner edge of which is fused into a glass tube 80 through which the leading-in wire 82 is sealed; or the outer edge may be fused into the neck of the bulb. In a R÷ntgenray tube a focusing-device for an incandescent filament cathode is supported by a ring in the manner described above.

Title: Improvements in or relating to electric blasting machines
IPC: F42D1/045
Filed: 1958-04-09
Abstract: 834,740. Driving dynamos. SCHAFFLERGLOSSL, H., and SCHAFFLER-GLOSSL, J., [trading as SCHAFFLER & CO.]. April 9, 1958 [April 17, 1957], No. 11252/58. Class 35. In a trip mechanism for preventing the connection of a hand-driven dynamo to a shotfiring circuit unless the generated voltage is adequate, the flux build-up in the generator stator is used to withdraw a restraining latch against spring pressure to enable the contact to be made. The dynamo pinion 25 is driven by a segment gear 4 on manually rotated shaft 2 which also turns a control disc 6 with lostmotion by means of a pin 5 in a recess. A pin 8 on a pivoted insulating disc 9 engages a similar recess in the under-side of the disc 6, and it is biased against one side of this recess by a spring 7. The disc 9 carries a contact member 11 which bridges contacts 13, 14, to close the firing circuit when clockwise rotation of the disc under the influence of spring 7 is permitted by the magnetic withdrawal of latch 15 from the path of arm 10 on the disc. The latch 15 is mounted on a leaf-spring 17 and is adjustably biased by a spring 22 in a hollow pole 21 projecting from the dynamo field core 24. When the dynamo speed is adequate, the self-excited field is sufficient to attract armature 16 to free the disc 9.

Title: Method and apparatus for producing a continuous thread covering on wire
Inventor: FUCHS HANS GEORG ALOIS
IPC: H01B13/08
Filed: 1962-03-23
Abstract: 969,974. Covering cores by winding threads. F. D. SIMS Ltd. March 25, 1963 [March 23, 1962], No. 11301/62. Heading B8G.  Wire 1 is given a first covering of thread by a spinner head 2 and a second covering of thread by a spinner head 3, there being a third spinner head 4 which, if the thread supply from the spinner head 2 or 3 fails due to breakage or exhaustion, automatically comes into operation at the correct instance and so eliminates the necessity for stopping the wire 1 whilst the thread supply from spinner head 2 or 3 is reestablished. The spinner heads are driven from a main shaft 6 via electric clutches 7, 8, 9 and each spinner head is associated with a thread break detector 10, 11, 12 coupled to a common control unit 13. If the thread from spinner head 2 fails the detector 10 causes the control unit 13 to disengage the clutch 7 and initiate engagement of the clutch 9 via a time delay so that a covering of thread is applied to the wire from the spinner head 4 just in front of the break in the covering applied by the spinner head 2. Tripping of the spinner head 2 also causes a warning device to indicate that spinner head 2 requires attention. After the spinner head 2 has been attended to it can be put back into use by manual control of the unit 13 and the spinner head 4 stopped and made ready for re-use. The sequence of operations if the thread supply from spinner head 3 fails is similar, with the exception that the time delay is appropriately shorter. When the spinner head 2 or 3 is restarted the spinner head 4 stops automatically after an appropriate time delay period equal to the time taken for the winding to reach the winding produced by the spinner head 4.

[Class 34 (ii)] In a drying-chamber 1 in which heated air is circulated and in which some moisture-laden air is recirculated without being reheated in a duct 6 separate from the duct 7 through which fresh air enters and passes over a heater 8, this heated fresh air is joined immediately before or upon its entering the chamber at 3 with the recirculated air, some of the recirculated moisture-laden air being discharged at 5 toatmosphere. Deflectors 11, 10 direct air through the duct 6, which may, however, contain a separate fan. The fan 9 may draw air at 5 over a heater, which may be byepassed, into a rotary drum 1 and discharges some of this air, returning part thereof to the drum through the duct 6. In a rectangular chamber A, a fan 9 forces fresh air over a tubular heater 8 into ducts 7, and air is recirculated by fans 13 in ducts 6, these streams joining at the entry ports 3 of the chamber, part of the used air escaping at 5. In Fig. 6, fresh air is drawn at 3 over a heater D into a chamber 1 by a fan 13, which returns part of the used air through a duct A and discharges part of it through a duct C. A vane E is adjusted to vary the proportion of air discharged.

Title: Improvements in or relating to the twisting of yarns
IPC: B65H59/36
Filed: 1936-04-24
Abstract: 473,436. Tensioning yarn during twisting. BRITISH CELANESE, Ltd. April 24, 1936, No. 11768. Convention date, April 24, 1935. [Class 120 (ii)] In twisting yarn by passing it through a device adapted to assist the twisting as it is withdrawn from a rotating supply package, change of tension is opposed by movement of a guide through which the yarn passes towards or from the axial line of the supply package. The invention is applicable to yarns of continuous or short filaments, or of natural fibres or mixtures, but is particularly applicable to yarns of fine denier and/or low tenacity and artificial filaments of organic derivatives of cellulose or of reconstituted cellulose. In the arrangement shown in Fig. 2, the yarn passes from the delivery flyer 4 through an eye in a weighted lever 20 and through a fixed eye 16 to the traverse guide of the winding-apparatus, the lever 20 moving upon any variation in tension to vary the path of the yarn through the guides in compensation. In the arrangement shown in Fig. 3, movement of a weighted lever 31, 33, varies the path of the yarn between guides 39, 40. A steam jacket 43, or any other device for applying lubricants, tints, sizes and the like to the yarn may be provided at a part where the path of the yarn does not change.

Patent GB-118098-A (GB)
IPC: F16H23/10
Abstract: 118,098. Michell, A. G. M. July 19, 1917, [Convention date]. Actuating pumps by fluid-pressure motors; valve-actuating arrangements.-A device for converting reciprocating into rotary motion or vice versa, applicable to air or gas compressors, pumps, &c., comprises an oblique swash plate 1 fixed to a shaft 2 and formed with plane faces engaged on one or both sides by slipper blocks 11, 12 connected by ball joints or other universal joints to reciprocating members, such as pistons 5, 5<A>. If the shaft is intended to rotate in one direction only, each block is jointed at a point behind its centre, as shown in Fig. 5, to allow a wedge-shaped film of lubricant to be formed between the bearing surfaces; for the same purpose the blocks 11, 12 may have relatively weak or flexible portions on one or both sides. The blocks are adjusted to take up wear by means of caps 12 screwing into the ends of the pistons 5 and locked by set-screws. Rotation of the blocks is prevented by projecting rings on the plate 1 in proximity to the inner curved edges of the blocks, or by projections 55, Fig. 5, engaging slots 53 in bars 8 which connect together pairs of pistons 5, 5<A>; a stud 54 fixed to the casing prevents rotation of the pistons. Fig. 4 shows the application to a steam-driven air compressor. Steam is admitted to a series of cylinders 6 by a rotary valve 34 on the shaft 2 and exhausts through openings 40. The steam pistons 5 are connected rigidly by bars 8 to pistons 5<A> in the compressing cylinders 6<A>. which are controlled by a rotary valve 26 on the shaft 2. To reduce clearance space, projections 29 on the pistons extend into valve ports 27. In the case of a single piston with a slipper block engaging one face of the plate 1, the return stroke of the piston may be effected by a spring placed in the cylinders or by pressure of the working fluid or by adhesion of the oil film between the block and the plate. The two faces of the plate need not be parallel, in which case the reciprocating members on the two sides have strokes of different lengths. The shaft 2 may be extended as shown at 2A in order to transmit power.
