Title: Improvements in or relating to machines for reeling paper or like webs
IPC: B65H18/20
Filed: 1934-08-10
Abstract: 419,133. Feeding webs. JAGENBERGWERKE AKT.-GES., 107, Himmelgeisterstrasse, D³sseldorf, Germany. Aug. 10, 1934, No. 23158. Convention date, April 5. Addition to 417,769. [Class 100 (i).] The machine for winding paper, cardboard, or like webs described in the parent Specification is modified in that one supporting-roller is mounted for free rotation, preferably in roller bearings, and the other supporting-roller is driven and provided with an elastic coating such as rubber. As shown, each supporting- roller 1, 2 is composed of a hard metal core k and an elastic rubber coating m. The roll 9 to be wound is pressed on the rollers 1, 2 by a roller 11 mounted on a pivoted lever 10. The web 12 unwinds from a reel 13 provided with an adjustable brake 17, passes around a guideroller 14, between slitting-rollers 15, 16, and between the rollers 1, 2 and roll 9. The roller 1 is mounted for free rotation, preferably in roller bearings, and the roller 2 is driven. In a modification, the web is guided by rollers to a point above the roll to be wound, between slitting-rollers, and then around the lower slitting-roller, which acts also as the pressure roller, to the roll to be wound. The first supporting-roller to contact the slit and wound web has a hard smooth surface, and is freely rotatable in roller bearings ; the other supporting-roller is mounted in roller bearings, is driven by a belt and pulley, and has a hard metal core surrounded by a rubber cover. The edges of the slit web will be pressed down and smoothed by the first supporting-roller, so that the rubber coating of the second roller will not be damaged.

Abstract: 615,379. Calculating-apparatus. REYNAL, J. L. C. Aug. 6, 1946, No. 23290. Convention date, March 16, 1944. [Class 106(i)] A calculating instrument is characterised by the combination of a support and rules movable on said support and each provided with scales according to one or more formulµ, with a transparent or perforated rule hinged about a point which is displaceable parallel to one of the edges of the support and to said scales in such a manner that one of the edges of said rule (or a straight line on said rule) can intersect all of the scales by swinging about the said point. As shown in Fig. 1, the invention takes the form of a " nomagraphic " slide rule comprising a body or support 1, two movable rules 2 and 7 and a transparent cursor 3 hinged at 4 to a slider 5 and carrying a reading line t. The scales x, y, z and u representing the variables of the equation or equations to be solved. The slider 5 has a flange 5a which frictionally engages in a groove 6 in the support 1, Fig. 2. In the embodiment shown in Fig. 3, rules 8 and 9 co-operate with rules 7 and 2 respectively and are movable with relation thereto. In this case the cursor 3 is secured to a slider 5a, movable in a groove 6a of the rule 2 and lockable by a nut 12, Fig. 4. If desired, the rule may have a transparent facing cover. The Specification describes an example of the use of the instrument for calculations relating to helical springs.

Title: Process for the hydrogenation of hydrocarbons
IPC: C10G45/32
Filed: 1966-05-25
Abstract: A process for hydrogenating a liquid hydrocarbon stream comprises (a) mixing the hydrocarbon stream at a temperature below 216 DEG  C. with a heated hydrogen-containing gaseous stream under conditions controlled to vaporize substantially instantaneously all the polymerizable components in the fraction, (b) introducing the mixture of step (a) into a reaction zone containing a hydrogenation catalyst, and (c) withdrawing the product from the reaction zone.  The feed stock may be a pyrolysis gasoline or dripolene which has previously been partially hydrogenated.  The dripolene or pyrolysis gasoline may be hydrogenated over platinum or palladium and fractionated; a fraction containing C6 to C8 aromatics is then processed according to the invention using a cobalt-molybdenum oxide catalyst.  The process reduces gum-forming dienes.  Pure aromatic hydrocarbons can be recovered from the C6-C8 fraction, e.g. by azeotropic distillation or liquid liquid extraction.

Filed: 1963-06-13
Abstract: Apparatus for compression-crimping yarn of the type having feed rolls, a compression crimping chamber, and a wheel to convey the plug of crimped yarn through an arcuate setting chamber - i.e. of the type described in Specification 1,051,721 - has means to produce a variably crimped yarn.  These means may comprise variable speed control means which vary periodically and either continuously or intermittently the speed of the feed rolls and/or the wheel and/or the yarn withdrawal means.  Alternatively or in addition the means may be formed by the periphery of the wheel having teeth of varying sizes, gaps of varying sizes between the teeth, or portions alternatively roughened - as by serrations or knurling - and polished, so that the grip of the wheel on the plug of yarn at the exit of the crimping chamber - and thus rate of movement of the plug - varies periodically, to produce a variably crimped yarn.

Abstract: 951,016. Coin-freed television apparatus. BRITISH TELEMETER HOME VIEWING Ltd. June 21, 1962 [June 22, 1961], No. 23910/62. Heading G4V. A subscription television system comprises a transmitter for transmitting programme material over a plurality of separate channels 10,12, 14, 16 to a subscriber receiver 18, means 20 at the receiver for selecting a desired one of the channels and for establishing a price demanded for reception of programme materials on that channel, and means 26 operable on satisfaction of the price demand for enabling reception of the programme material by the subscriber. Each of the channels carries a programme valued at a different price and is connected to respective terminals 20B, 20D, 20F and 20H of the selector switch 20. The arm of the switch is movable to a selected one of the terminals and is connected to a disc 28 rotated with the arm. The disc has a stop 30 engaging a stop 36 on a ratchet wheel which is thereby rotated to a position corresponding with the selected channel. The subscriber then depresses a switch 40 to connect a rectifier and filter unit 22 to a solenoid 46, the armature of which moves against a spring 50 to engage the ratchet wheel and prevent its rotation in a direction other than that necessary to move in a direction corresponding to movement to a channel of lower price value. When coins are put into a collector and sizer unit 52, which omits electrical impulses dependant on the size of the coin, a solenoid 54 is actuated and its armature turn the wheel 34 in the direction of decreasing price until the correct amount has been inserted in the sizes when a switch 26 is closed so that the subscriber can receive the selected programme. At the end of the programme, a pulse is transmitted on the same channel and a detector 62 closes switch contacts 60A, 60B to de-energize the solenoid 46 so that its armature releases the wheel 34 which returns to the position it was in when the programme was selected, the switch 26 opening to render the receiver inoperative. If, while receiving a programme, the subscriber moves the arm of the switch 20 towards another contact connected to one of the other channels, the arm engages one or other of contacts 20C, 20E or 20H to cause the solenoid 46 to be de-energized and the wheel to rotate opening the switch 26. In an alternative embodiment, the programmes are transmitted by different carrier signals carried on a single line, such as a coaxial cable, and a tuner is associated with the switch to select a desired programme.
