Title: Multiple beam cathode ray tube arrangements
IPC: H04N9/28
Filed: 1970-07-22
Abstract: 1323903 Cathode-ray tube circuits LICENTIA PATENT - VERWALTUNGS - GmbH 22 July 1970 [28 July 1969] 35409/70 Heading H4T In an arrangement for correcting corner convergence errors in a multiple beam cathode-ray tube the line scanning coils, comprising two similar portions symmetrically positioned about the tube neck, are connected in parallel and supplied with a convergence correction current in such manner that it is superimposed additively on the scanning current in one portion and subtractively on the scanning current in the other coil. Fig. 3 shows an embodiment in which the scanning coil portions 5, 6 are (effectively) connected in parallel across the windings 7 on the line scan transformer 8 via the centre-tapped secondary winding 9 of a transformer 10. The convergence correction current, comprises a 3 kHz component which is amplitude modulated at frame frequency and effective during line trace periods and a 40 kHz component effective during line fly-back periods and is produced by respective oscillatory circuits which have the primary winding 13 of transformer in common. During line trace periods the inductance of winding 13 is loaded by capacitors 14, 23 and 25, 26 and a resonant circuit (3 kHz) is formed between tapping 15 on winding 16 (also on the line transformer 8) to which a frame frequency sawtooth wave is supplied via amplifier 17 from the frame scan generator 18 and during line fly-back periods the fly-back pulses 21, 22 cutoff diodes 19, 20 thereby removing the capacitors 25, 26 from the resonant circuit which now oscillates at 40 kHz. Because the convergence errors increase from the centre towards the ends of the line scans close coupled windings 27, 28 resonant at 18-20 kHz are connected in series with the coils 5, 6 to "distribute" the correction effect appropriately.

Title: Improvements in processes and apparatuses for the conversion of hydrocarbon oils
IPC: C10G9/00
Filed: 1920-12-22
Abstract: 168,573. Emerson, V. L. May 6, 1920, [Convention date]. Hydrocarbons, c r a c k - ing.-Heavy hydrocarbon oils are converted into lighter hydrocarbons by concussive impact. The vapours from a cracking- still 1 are passed by a pipe 2 to a chamber 3, in which opposing jets of the vapours are brought into violent impact. The vapours are then passed by a pipe 7 and perforated nozzle 9 into a bath 8 into which oil to be treated is fed by a pipe 49, and from which the, heated oil is withdrawn by a pump 61 and supplied to the still 1. The impact may be produced by injection of the vapours through a jet against a baffle. The jets are preferably connected by a pipe 11 to the bath 8 so that the jets will entrain liquid which will be subjected to impact with the vapours. The vapours from the bath 8 pass through a series of condensers 16, 17, 18 in which cold water is passed through the condenser 18, and, after being heated therein, is passed into condenser 17, in which steam in generated, the steam being passed through the condenser 16. A series of trays 30, 31, 32 with bubbling-hoods arranged at the base of the condenser 16, and trays 39, 40 between the condensers 16, 17, are provided with pipe connections to cause the condensates to flow down the trays and return to the bath 8, or to withdraw them. The lower end of the condenser 18 has a water trap 53 and a connection 57 to a final condenser 58. The still 1 is provided with devices to promote circulation of the oil, and to shut off the draught if oil leaks into the firechamber or if the temperature of the flue gasesbecomes excessive, of the kind described in Specification 163,277. The impact apparatus described in Specification 163,277 in which the opposing jets are arranged in a chamber over the oil bath, and in which the vapours pass into the oil bath through a perforated bell-shaped mouth, may also be used.

Title: Improvements in or relating to buffer devices for arresting the movement of rolled stock
IPC: B21C47/24
Filed: 1967-08-07
Abstract: 1,200,073. Buffers; dashpots. VEREINIGTE OSTERREICHISCHE EISEN-UND STAHLWERKE A.G. 7 Aug., 1967 [31 Aug., 1966], No. 36224/67. Heading F2S. A buffer for stopping an item of rolled stock, such as a coil 2 formed of rolled metal strip, at the end of a conveying path 1 consists of a stop member 7 connected, e.g. by a lever system 6, to a spring assembly which resiliently absorbs the inpact and is in turn connected to a dashpot which allows substantially undamped inward movement of the springs but which damps the return stroke. The degree of damping is adjustable, the desirable setting being such that the energy stored in the spring during the inward stroke is just absorbed by the dashpot in the return stroke so that the stop returns to its initial position without overshoot. The spring assembly consists of two units 9 as in Fig. 1, each comprising a coil spring 15 mounted in a telescopic housing. These two units, as depicted in Fig. 3 (not shown), are mounted on opposite sides of a median plane of the apparatus (parallel to the plane of Fig. 1) with the dashpot between them. Dashpot Construction (Fig. 4).-A main piston 24 operated in a cylinder 28 which, through a duct 29 communicates with a second cylinder 34 having a spring-loaded piston 41. Liquid fills the space above pistons 41 and 24 as well as the communicating passages between them, both cylinders 34 and 25 being open to the atmosphere by way of ports 48 on the side of their respective pistons remote from the liquid-filled volume. When the springs, and hence the piston-rod 23 of the dashpot, move inwardly the pressure on the liquid between the pistons falls and this opens a valve 35 which normally obstructs the flow from the duct 29 by way of a duct 30 to cylinder 34. This allows the spring 43 associated with piston 41 to force fluid into the space vacated by the piston 24 as it moves inwardly. This inward movement is substantially undamped, but on the return stroke of the piston 24 valve 35 closes and fluid flow is restricted to the path via port 32 controlled by adjustable needle valve 40 and passageway 33 to cylinder 34. The cylinders are initially supplied with an appropriate quantity of liquid by way of a filler passage 46 and any subsequent change in the volume of liquid in the system affects the extent of projection of a rod 42 associated with piston 41. This rod carries a switchoperating member 50 which, in the event of excessive loss of liquid, operates a switch (not shown) to signal that refilling is necessary. To prevent creation of vacuum in the liquid filled part of the system in consequence of a sudden inward displacement of piston 24, a reservoir (not visible in Fig. 4) may be connected to duct 29. Such reservoir may consist of a liquid filled balloon or (Fig. 5, not shown) a cylinder fitted with a spring loaded piston, so that whenever an overpressure exists in the liquid the reservoir is filled with liquid and in the event of an under pressure arising this liquid is discharged into the dashpot space.
