Patent GB-501253-A (GB)
Title: Improvements in or relating to x-ray tubes
IPC: H01J35/10
Filed: 1938-07-29
Abstract: 501,253. R÷ntgen-ray tubes. NAAMLOOZE VENNOOTSCHAP PHILIPS' GLOEILAMPENFABRIEKEN. July 29, 1938, No. 22626. Convention date, Aug. 2, 1937. [Class 39 (i)] In an X-ray tube in which a heavy anode is journalled on ball-bearings, the mechanical connection between that part of the anode on which the operating heat is developed and the bearing members has so slight a thermal conductivity that substantially no conduction of heat takes place from the heated member to the bearings, and, on the other hand, the bearings are connected to conduct heat to members adapted to be cooled during operation. In the form shown in Fig. 1. a metal block 7 is sealed to the glass 6, and carries in a bore bearing 9, 10, supporting a shaft 11, on the front end of which the anode 14 is supported by a disc 12 and a thin-walled tube 13 of ferrochromium. The anode comprises a tungsten disc 16, and a copper mass 14 with a skirt 15 which acts as the rotor for the electromagnetic drive. A screw 18 protects the cylinder 13 from electron bombardment. The block 7 may be cooled from the outside so that this, together with the low conductivity of the tube 13, keeps the bearings 9, 10 cool, so that they neither give out occluded gas nor does the vacuum grease with which they are lubricated evaporate appreciably. Any grease which is vaporized is condensed in the narrow core passage between the block 7 and skirt 15. The glass 2 is connected to glass 3 by a ferrochromium cylinder 1. On the glass 3 is mounted the cathode assembly, comprising a concentrating cylinder and screen 29, cathode 28, and a partition 22, separating off a space in which is mounted a heater 23 and a getter receptacle, e.g. a copper tube filled with barium. The getter may be vaporized when desired, and, deposited on the walls of the space which communicates with the tube only through a hole 26, is protected from the impact of accelerated ions. The window 30 in the screen 29 is of beryllium and the window 31 of glass. In a modified anode mounting, Fig. 2, a metallic plate 8 is sealed to the glass 6, and carries the bearings 9, 10. In this construction the ferro-chromium tube 17 is directed backwardly from the bearing and secured to the rear end of the anode 14. The plate 8 may be artificially cooled.

Title: Improvements in or relating to telephone systems
IPC: H04Q3/00
Filed: 1929-07-24
Abstract: 337,015. Automatic Telephone Manufacturing Co., Ltd., Gillings, C., and Paulett, W. H. July 24, 1929. Automatic and semi-automatic exchange systems. - A bi-directional rotary connector which is adapted to hunt successively over several levels and is released either rotarily or completely after an unsuccessful search over a level is controlled as regards its vertical movement by an auxiliary switch which receives the last numerical digit and marks successively each level forming part of the wanted group. By this arrangement the levels allotted to any particular group are not necessarily contiguous. Fig. 1 shows a connector having two sets of wipers adapted for simultaneous hunting under control of a shunt-field relay G and a vertical wiper VW engaging a vertical bank VB adapted to be. marked by the auxiliary switch MS. The connection y is employed in place of the connection x when all the levels are required for a single group. It is assumed that the wanted group occupies levels 3-6 and 0. The last numerical digit 3 is repeated by line relay A to the magnet MSR of the switch MS to mark the level 3 in the bank VB. Relav C falls back at the end of the train and connects up relay G, which interacts with the vertical magnet VM until the level 3 is reached, when relay G is held over the marking circuit in series with relay VS, which locks and transfers the stepping circuit to the rotary magnet RM. The windings of relay G are now connected to the test wipers P1, P2 and this relay continues to energize intermittently so long as both wipers encounter busy lines. If all the lines in the level are busy, cam springs S are operated in the eleventh position, disconnecting relay VS and energizing the rotary release magnet RZ. An impulse is sent at contact rz2 to the magnet MSR of the switch MS, and level 4 is now marked for hunting. In position 7 of the switch MS, an overflow meter OF is connected up in place of the rotary release magnet RZ, and is actuated if all the lines of the group are busy, busy tone BT being transmitted. If an idle line is found, relay G fails to energize, and one or other of the switching relays HA, HB pulls up and applies ringing current over ring cut-off relay F in the usual manner. When all the levels accommodate a single group, the last digit serves only to energize relay C, which sends an impulse over the connection y to advance the switch MS one step. In a modification, the ordinary release magnet Z is arranged to operate after an unsuccessful search over a level. Fig. 3 shows the relays and jumpers required to cater for three groups comprising in the first instance levels 1, 2, levels 3, 4 and 5 and level 6, and designated by the final digit 1, 2 or 3. The initial setting of the switch MS causes the operation of one of the relays SA, SB, SC to complete the appropriate 'connections to the vertical bank VB and to the release magnet and overflow meter. Additional levels may be allotted to the groups at a later date by means of the connections shown in dotted lines.

Title: Improvements relating to the manufacture of films, celluloid-like masses, blocks andother products or articles
IPC: C08L1/26
Filed: 1920-08-04
Abstract: Films, sheets, celluloid-like masses, blocks, rods, tubes, threads, filaments, and other articles are made from ethyl, methyl, benzyl, and other ethers of cellulose by running, casting, pressing, moulding, extruding, or otherwise working the ethers when in a melted condition; the temperature at which the mass attains the necessary fluidity depends on the nature and quality of the ether and in the presence of admixtures, but in no case is it below 100 DEG C. The reduction to the melted condition may take place before casting, moulding, extruding, etc.; or the ethers or mixtures containing them may be pressed into heated moulds or may be extruded from heated containers. The ethers may be mixed with nitrocellulose, cellulose acetate, and other esters of cellulose, and with the mass may be incorporated plastifying-agents, filling and colouring materials and in some cases a limited proportion of volatile solvent; the latter, in the case of blocks, facilitates the subsequent cutting into sheets, &c.

Title: Oil additives
IPC: C10M151/02
Filed: 1965-05-31
Abstract: A lubricating oil has dissolved therein a dispersing agent comprising a graft polymer, prepared in the presence of a free radical catalyst, of (1) a preformed oil-soluble homo- or copolymer of acrylic or methacrylic acid esters, and (2) an ethylenically unsaturated monomer containing a tertiary nitrogen atom, the graft polymer containing 2 to 30% by weight, based on the weight of polymer (1), of the monomer (2).  In examples (1) is a copolymer of methyl methacrylate and methacrylic acid esters of fatty alcohols and (2) is N-vinyl pyrrolidone.ALSO:A preformed oil-soluble homo- or copolymer of acrylic or methacrylic acid esters is subjected to graft polymerization with an ethylenically-unsaturated monomer containing a tertiary nitrogen atom in the presence of a free-radical catalyst, whereby a graft polymer is formed containing 2 to 30% (based on the weight of preformed polymer) of the said monomer. The preformed polymer may be prepared in bulk or emulsion, followed by dispersion in the N-containing monomer, or prepared in solution e.g. in oil and said monomer added thereto. Specified base polymers are homopolymers of acrylic and methacrylic acid esters of alcohols containing at least 8 carbon atoms and copolymers of these monomers with esters of fumaric or itaconic acid and alcohols containing 8 to 18 carbon atoms, with vinyl acetate, or with compounds of which the homopolymers are oil-insoluble e.g. acrylic and methacrylic acid esters of alcohols with 1 to 4 carbon atoms, or with aminoalkyl esters e.g. dimethyl aminoethyl methacrylate, di-n-butylaminoethyl acrylate, dimethylaminobutyl acrylate and n-butylaminoethyl methacrylate.  The tertiary nitrogen-containing monomer is e.g. an N-vinyl lactam such as N-vinyl-2-pyrrolidone, N-vinyl-caprolactam, N - vinyl - 3 - methyl pyrrolidone, N-vinyl - 5 - piperidone and N - vinyl - 4 - n-butyl caprolactam or the corresponding thiolactams. Cyclic N-vinyl imides e.g. N-vinyl succinimide, N-vinyl-a -methyl succinimide and N-vinyl phthalimide may be used as can N-vinyl oxazolidones and N-vinyl carboxylic acid amides e.g. N-vinyl-N-ethylacetamide and N-vinyl-N-methyl benzamide.  The free radical catalyst is e.g. azodiisobutyronitrile, tertiary butyl perbenzoate or tertiary butyl hydroperoxide. The aminoalkyl esters specified above may be grafted on to the preformed polymer along with the tertiary nitrogen containing monomer. In the examples, the monomer used is N-vinyl pyrrolidone, together with N-dimethylaminoethyl methacrylate in Example 3. The base polymer is a copolymer of methyl methacrylate and a mixture of methacrylic acid esters of fatty alcohols and the catalyst is tertiary butyl perbenzoate.

Abstract: 1,006,973. Drawing mandrels. AVESTA JERNVERKS A.B. June 15, 1962 [June 30, 1961], No. 23202/62. Heading B3P. A drawing mandrel of hard metal is provided with a steel extension which remains in the tube when the mandrel is pulled out at the end of the drawing operation, and prevents rapid lateral movements of the mandrel. The mandrel 10 is fitted on to the pull rod 12 and is retained by a hardened steel nut 15. The free end of the nut is formed to a ball 15 of slightly smaller diameter than the mandrel. The tube 16 is drawn over the mandrel and through a die 17. A tube guide 18 is positioned opposite the ball 15, and has a diameter equal to or slightly larger than the outside diameter of the tube. The mandrel 10 may be a push fit or a force fit on the pull rod 12 and there is a soldered joint 14 between the nut 13 and the mandrel. At the end of the drawing operation, when due to the elastic contraction of the tube and pull-rod the mandrel suddenly leaves the end of the tube, the ball 15 remains within the tube. In a modification the ball 15 is slightly larger than the bore of the tube and is slit to form a plurality of resilient segments. In a second modification the guide 18 is used as a second drawing die, and the end of the nut is made parallel and acts as a second drawing mandrel. The strength of the soldered joint 14 may be increased by making the mating faces conical in form. The mandrel 10 may be formed with a sharp leading edge to remove weld or burrs from the inside of the tube.
