Title: Electronic tube with secondary emission
IPC: H01J43/16
Filed: 1936-10-08
Abstract: 486,657. Cathode-ray tubes; electron multipliers. RADIOAKT.-GES. D. S. LOEWE. Oct. 8, 1936, No. 27319. Convention date, Oct. 16, 1935. [Class 39 (i)] In an electron-discharge device in which an electron-optically concentrated ray is focused onto a secondary emission target, this target is electrically heated by a separate source in order to increase the secondary emission. The effect may be observed in the tube shown in Fig. 1, in which a cathode 1, anode 2 and lens 4, 5 produce an electron beam focused on a screen 6 which may be directly heated by a battery 8 and adjustable resistance 9. Secondary electrons from 6 are collected by a positive grid 7, 7a and registered by the galvanometer 10. With a nickel target coated with an emissive oxide such as barium oxide and adjusted to give thermionic emission of only one division, a primary beam of 3 divisions gave a secondary emission of about 100 divisions. In the television transmitting tube shown in Fig. 2, a primary photo-electric screen 31 emits an electron image of the object 16, the image being focused magnetically by coil 18, or electrostatically by electrodes 17, 17a, and deflected by magnetic field 20 onto a mosaic electrode 19, which is heated by the filament 36 or by electron bombardment. The electrode 19 is a finely divided nickel surface deposited on a mica support 19a backed by a signal electrode 19b. The mosaic, charged positively by secondary emission, is scanned by an electron beam, generated and deflected in the normal way, (deflecting plate 30 shown), the resulting impulses being conveyed by the signal plate 19b to the valve amplifier 32. The scanning beam may be modulated with a carrier frequency. The Specification as open to inspection under Sect. 91 includes the subject-matter of Specifications 486,750 and 486,915, and describes also a photo-electric cell, Fig. 3 (Cancelled), in which a heated filamentary secondary emitter 6 is surrounded by a collecting anode 7 and amplifies the current from the ,primary cathode 12. The secondary emitter may be a series of hairpins, as shown, or a single filament surrounded by a cylindrical anode. It is stated that the target may be heated by induction. This subject-matter does not appear in the Specification as accepted.

Title: Process for the manufacture in continuous lengths of bodies which are hollow or contain gaseous bubbles or have a tubular structure from solutions or pseudo-solutions of cellulose esters or ethers
IPC: B29C48/05
Filed: 1929-09-10
Abstract: 318,970. Soc. des Usines Chimiques Rhone-Poulenc. Sept. 13, 1928, [Convention date]. Yarns and threads.- Bodies which are hollow or contain gaseous bubbles or have a tubular structure, are obtained by the evaporation of solutions of cellulose esters or ethers applied as a film or coating to a thread or a number of threads, and then causing a development of gas to take place while the material is on the support by raising the whole to a temperature suffidently high to cause ebullition of the solvent. For example, a solution of cellulose acetate in acetone may be applied to a silk thread by extruding the solution from a die through which the thread passes, to give a product which on heating to 110 C. assumes the section shown in Fig. 1, or a ribbon with tubular edges may be formed similarly between two threads as shown in Fig. 2, and this may be extended to the simple tubular form illustrated in Fig. 3, by causing a more active vaporization of the solvent as by heating to 150 C.; alternatively, the form shown in Fig. 4 may be obtained by the use of three thread supports. The thread &c. constituting the support may be allowed to remain in the finished article or it may be separated either mechanically or by solution; alternatively, the support may be of the same nature as the material constituting the basis of the solution. Colouring matters, softening agents &c. may be added to the solution, of the cellulose ester &c. Specifications 302,115 ; and 318,250, [Class 2 (ii), Cellulose &c.], are referred to. The Specification as open to inspection under Sect. 91 (3) (a) refers to the application of the process to solutions of gelatine, colloidal cellulose, indiarubber and of plastic materials; and it refers also to the obtaining of the hollow form by a reduction of pressure. This subject-matter does not appear in the Specification as accepted.

Title: Method and apparatus for the continuous curvilinear pleating of thermoplastic films or foils
IPC: B29C53/04
Filed: 1958-09-01
Abstract: <PICT:0856492/IV(a)/1> A method for the continuous curvilinear pleating of thermoplastic films comprises first subjecting the film to an operation producing rectilinear pleating transverse to the longitudinal direction of the film, and then advancing the rectilinearly pleated film while it rests loosely on a smooth support, the shape of which changes gradually from a level part to a part having a form corresponding to the desired curvature of the pleats, the film being heated during its advance to soften it so that the pleats curve to take the shape of the support owing to their own weight, whereafter the curvilinear pleating so produced is stabilized by cooling during the further advance of the material while it still rests loosely on the support.  Apparatus as shown comprises an unrolling mechanism 2, 3, a heater 4 and rectilinear pleating mechanism 5, and a support having a level portion 6 just beyond the pleating mechanism and then gradually curving to a form corresponding to the generatrix desired for the curvilinear pleats 10, heaters 8, 9 being provided above and below the support at its zone of change of curvature and means preferably being provided beyond the heaters for promoting or delaying the cooling of the film to stabilize the curvilinear pleats (e.g. means for adjusting the support into various inclined positions so as to promote or retard the advance of the film).  The support may be fixed, or an endless steel band may be used, made to curve in the same manner as a fixed support by suitably placed rollers.  The rollers may be movably mounted so that the curvatures can be altered.  The support may also consist of a series of parallel threads which are stationarily stretched, or endless, passing over rollers.

Filed: 1973-06-15
Abstract: 1446777 Tyre building apparatus NATIONAL-STANDARD CO Ltd 14 June 1974 [15 June 1973] 28522/73 Heading B7C A tyre building apparatus including a radially expansible and contractible former 4 further includes end assemblies 5, 6 for engaging the tyre beads 152, and for tensioning the tyre components by axial movement of the end assemblies relative to the former when the beads are engaged. The end assemblies are axially movable symmetrically relative to the mid-plane 25 of the former 4 by means of two racks 162, each connected to a respective end assembly, meshing with a pinion 164. The former 4 comprises a plurality of segments 8 of interleaved circumferentially extending members 62, 63. In operation, a preformed carcass (e.g. of radial type) is placed over the former 4, and air is introduced into spaces 126 to pivot the fingers 146 to their bead gripping positions (such positions being determined by adjustable stop collars 166 abutting flanges 116). Air is then introduced into spaces 94 to move tubes 80 and members 84, 132, and 102 connected thereto and the fingers 146 axially outwardly until member 84 of end assembly 6 engages an adjustable stop 171. Thus the carcass is tensioned to a desired extent. The relative axial positions of members 132, 84 are adjustable by means of collars 138. Rotation of shaft 57 causes expansion of the former 4 by means of axially inward movement of nuts 30 and pivoting of segment support arms 17. Simultaneously tubes 90 secured to the nuts 30 are moved axially inwards, and interconnected members 102, 132, 84, tubes 80 and fingers 146 are also moved axially inwards due to expansion of the former. The air pressure in space 94 thus retains the carcass in tension during shaping. In an alternative embodiment (Fig. 8, not shown) turn-up of the carcass ply about each of two axially spaced, bead cores is effected by a respective bladder (172) carried by the fingers 146a) of an end assembly.
