Title: Improvements in or relating to electric discharge tubes with focused beams
IPC: H01J21/02
Filed: 1946-09-27
Abstract: 669,383. Electric discharge tubes. PHILIPS LAMPS, Ltd. Sept. 27, 1946 [May 7, 1943], No. 28913/46. Class 39 (i). An electric discharge tube in which an astigmatic beam of electrons is focused by means of a cylindrical or prismatic electron mirror so that it converges upon an anode, collecting electrode or fluorescent screen, its point of incidence thereon being controlled by means of a variable electric field, is characterized in that the focal length of the mirror increases progressively from one end of the mirror to the other and that foci of the mirror lie both behind and in front of the anode, collecting electrode or fluorescent screen. The progressive increase in focal length may be continuous or discontinuous, the mirror comprising a series of component curved surfaces whose curvature is constant in each component surface. The mirror may comprise a series of flat portions tangential to a curved surface having the requisite progressively increasing curvature. In the construction shown in Fig. 5 the deflection is varied by varying the potential of the electron mirror 1. In the construction shown in Fig. 6 two anodes 5, 6 are provided and control deflection of the beam is produced by the electrodes 7. In the construction shown in Fig. 7 electrons emitted by the cathode 8 are formed into a beam directed on to a fluorescent screen 10 by the mirror 9. Deflecting electrodes 11 cause the beam to sweep to and fro over the screen 10, a sharp boundary between light and dark on the screen being produced owing to the curvature of the mirror 9.

Title: Alkylate having improved sulfonated characteristics
IPC: C07C2/70
Filed: 1955-10-11
Abstract: Alkylbenzenes having improved sulphonating characteristics, are produced by alkylating benzene with olefin polymer fractions containing 8-18 carbon atoms per polymer molecule, forming an intimate mixture of the alkylate with substantially anhydrous hydrofluoric acid and benzene, settling the resultant mixture to separate a predominantly hydrocarbon layer and an acid layer, and fractionally distilling the hydrocarbon layer to separate hydrofluoric acid and benzene from the treated alkylate.  In an example, benzene was alkylated with a propylene polymer having a B.P. of 359-434 DEG  F. and then vigorously mixed with anhydrous hydrofluoric acid and benzene at 70 DEG  F. for 10 minutes. Subsequently it was stirred for 15 minutes to separate an upper hydrocarbon layer and a lower acid layer, the former being removed, washed, distilled and finally steam stripped to remove the major part of the benzene.  The alkylate was sulphonated by passing a stream of air and SO3 containing 5 to 10 per cent SO3 through the alkylate at 50 DEG  C. until sulphonation was complete.

Abstract: 1305234 Cathode-ray tube circuits INTERNATIONAL STANDARD ELECTRIC CORP 16 June 1970 [23 June 1969] 29015/70 Heading H4T In an arrangement for dynamic (horizontal and/or vertical) convergence of the beams of a plural beam colour-television picture tube, a parabolic wave derived by integration of the H and/or V deflecting waveform is divided into two portions corresponding to respective halves of the deflecting waveforms and the divided portions are fed to the appropriate convergence coils via individual amplitude control means. Fig. 1 shows an embodiment for horizontal convergence in which the parabolic waveform 32 (Fig. 2)-which may be derived from the S- correction capacitor-is fed to terminal 1 and divided into symmetrical halves by means of switching diodes 5, 6 and 8, 9 supplied with switching waveforms 33, 34 (Fig. 2) via terminals 2 and 3 respectively.

Classes 120(2) and 120(3) Air drawn through nozzles of a suction system in a spinning or like machine is blown without prior filtering through a duct or ducts having porous walls so that air may pass out while broken threads, dust and fly are carried to that end of each duct remote 'from the fan. It is stated that the air should preferably enter each duct at a velocity of at least 6 meters per second. In one form, a fan 7 draws air through a central collecting passage 6 with which thread suction nozzles communicate and passes it to a duct 9 extending over the length of the machine creel. The wall of the duct may be of woven or braided material, such as smooth metal, wires or single threads of synthetic fibre, e.g. nylon. Alternatively, the duct wall may be made of perforated foil. The air stream is introduced to the duct at such high velocity that the entrained material is carried to the end 10 of the duct while the air passes through the wall. An elbow on the end 10 may lead the entrained material into a removable container. In another embodiment, the fan is mounted at the end of the duct 9. In addition to the duct above the creel, ducts may - be located beneath the drafting rollers and near to the spindles. Specification 751,043 is referred to.

Abstract: 1,110,912. Control systems for discharge lamps. GESELLSCHAFT FR MULTIBLITZGERATE DR. ING. D.A. MANNESMANN m.b.H. 12 July, 1965 [16 July, 1964], No. 29410/65. Heading H2H. [Also in Division G2] The light source in a photographic reproduction apparatus such as an enlarger comprises a tubular discharge lamp 7, coiled into a helix so as to reduce its size. It is supported by a hollow lamp socket 12 in a housing 15, through which cooling air can be blown on to the electrode seals 8 and through the helix itself. The lamp is operated under stroboscopic conditions, that is, to give a rapid sequence of short flashes within the normal exposure time. This is effected by the circuit of Fig. 4. The lamp is connected to two low capacity capacitors 17, 18, respectively of 0-1 pF and 1 pF. These are charged with 3200 volts via a fullwave rectifier 21 from a mains transformer 22, 22<SP>1</SP>. The lamp ignition electrode 9 is connected via an ignition transformer 24 to a capacitor 25 which is charged with 500 volts from a transformer 28 and rectifier 27, which is also supplied to the anode of a thyratron 26. The first grid 26<SP>1</SP> of the thyratron acts as a control grid, and the second grid 2611 as a blocking grid. When switch 30 is closed, pulses applied to the ignition electrode 9 cause a pre-ionization of the discharge gap without a discharge actually striking, since contact 23 remains open. A time-delay relay 32 then comes into operation to close contact 23, and so initiate the striking of the discharge in lamp 7. As long as switch 30 remains closed, the discharge takes place with double the mains frequency, producing very short intensive flashes of light. The lamp 7 is disposed within a reflector 5, the light passing through a frosted glass sheet 6 and a condenser lens 4, and down on to a worktable 2.
