Title: Improvements in Disc Brakes
IPC: F16D55/224
Filed: 1966-08-01
Abstract: 1,190,762. Feeding webs. MASSON SCOTT THRISSELL ENG. Ltd., and G. A. B. BYRT. 31 July, 1967 [1 Aug., 1966], No. 34499/66. Heading B8R. [Also in Division F2] In a disc brake of the type having a pair of pads 5, 6 mounted one on each of a pair of pivoted brake arms 7, 8 a brake pad 5 is adjustable in position along its brake arm 7 to be engageable with the disc 1 at different positions to vary the ratio of the displacement of the pad from the axis of pivoting of its brake arm to that from the axis of rotation of the shaft 2 of the disc so as to vary the braking torque applied to the shaft. The disc brake may control the braking of a reel 4 containing a thread, a web or sheet, such as paper for supplying a printing machine. The pads 5, 6 are held out of engagement with the disc 1 by a spring 11 and the braking force may be halved by adjusting a screw 15 against a stop 17 so that the brake arm 8 cannot move the pad 6 into engagement with the disc 1. Screws 18 enable the position of the pad 5 to be adjusted radially within a slot 19. The braking arms 7, 8 are moved by air-actuated diaphragm cylinders 12 and 13 the air supply to which may be controlled by a dance roll around which, the web thread or paper passes so that the dance roll is responsive to the speed and amount of material remaining on the reel 4. The cylinder 12 may be arranged to provide a small predetermined braking torque to the shaft 2 and when it is required to stop the reel 4 the air supply is also switched to the reserve cylinder 13 the air supplied being responsive to the dance roll.

Filed: 1974-08-06
Abstract: 1478639 Hydrocyclones GEORG FISCHER AG 6 Aug 1974 [7 Aug 1973] 34675/74 Heading B2P [Also in Divisions B3 and F4] Molten metal on its way to a continuous casting mould is forced to undergo a vortical flow in a stationary swirl chamber 4 so that contaminants of comparatively low specific gravity are separated and discharged from the chamber and the contaminant-free metal is conveyed to the mould. As shown in Fig. 2, a swirl chamber 4 is incorporated at the inlet end of a tundish 8. In other embodiments it is incorporated either in a dam dividing the tundish into two basins or at the outlet, which is controlled by a gate valve. The inlet 3 is tangential to the chamber 4, which may be of corundum for wear-resistance; there is a bottom radial outlet 5 for the metal and thus the tundish slag layer is undisturbed. The contaminants are allowed to run away by way of a weir 6, e.g. to a tundish overflow 7. In Fig. 7, the swirl chamber 4 is located in the flow path between the tundish and the mould 17, the tundish outlet forming the inlet 3 to the chamber and having a gate valve 12. The contaminants connect at the chamber top and run over unhindered.  There may be a number of swirl chambers in series or parallel.

Patent GB-380316-A (GB)
Title: Improvements in or relating to keying arrangements for wireless telegraphic transmitting apparatus
IPC: H04L27/04
Filed: 1931-12-15
Abstract: 380,316. Wireless transmitting systems. LORENZ AKT.-GES., C., 1, Lorenzweg, Tempelhof, Berlin. Dec. 15, 1931, No. 34741. Convention date, March 31. [Class 40 (v).] In a radio transmitter employing an oscillator and an amplifier, and wherein means are provided for preventing sudden changes in the radiated carrier when keying, the oscillator is arranged to be brought into action slightly before, and to be quenched slightly after, the emission of each signal. Fig. 1 shows an oscillator valve S coupled to an amplifier H, the local oscillator being started and quenched by closing and opening its grid circuit at r2 or r12, and the amplifier controlled by opening and closing a short circuit r13 across the grid bias source. The signal shape is rounded by interposing a network D between the bias source and the amplifier grid circuit. When the signal key T is closed, a relay R1 closes first the contact r13 to bring the amplifier gradually into action. Contact r11 also closes to energize a second relay R2 and to close its contact r2. When the key is opened, contacts r11, r12, r13 open at once, the contact r13 gradually quenching the amplifier H. Contact r12 is ineffective because it is shunted by contact r2, and contact r11 de-energizes the relay R2 slowly on account of the shunting condenser C. Contact r2 then opens, and the oscillator is quenched. Fig. 2 shows a system employing a reversing key T which, when pressed, energizes a relay R1 and when released energizes a relay R2. These relays control respectively a contact r1 in the amplifier bias circuit and a contact r2 in the oscillator grid circuit. On account of the time taken in moving the key, the oscillator starts up slightly before, and continues in operation slightly after the beginning and end of the radiated impulse. The retarding network D may be arranged in the plate circuit, instead of the grid circuit, of the amplifier H. The rounded form of the signals tends to prevent interference with adjacent receivers, and the absence of continued oscillations in the oscillator facilitates duplex operation.
Patent GB-429949-A (GB)
Title: Improvements in or relating to the production of unsaturated ethers of cellulose
IPC: C08B11/04
Filed: 1933-12-11
Abstract: Unsaturated ethers of cellulose of low inflammability are prepared by reacting a cellulosic material in the presence of a base and at an elevated temperature preferably between 70 and 160 DEG  C. with a halogenated olefine containing at least 3 and preferably not more than 9 carbon atoms in the molecule and in which at least one halogen atom is attached to a double bonded carbon atom, and at least one other halogen atom is attached to a fully saturated carbon atom, and in particular to a carbon atom immediately adjacent to a double bonded carbon atom.  The halogen substituents attached to the double bonded carbon atom are unreactive and remain unattached throughout the etherification, whereas the other halogen atom is highly reactive.  The cellulosic material treated may comprise cotton linters or wood pulp, or a pre-treated cellulose such as hydro cellulose or oxidized cellulose, or partially substituted cellulose such as a low methyl cellulose, or esters such as formates.  The etherified cellulose is preferred to the esterified cellulose.  The cellulosic material may be converted to an alkali cellulose before the reaction either by forming the alkali cellulose in situ or more usually by steeping in a large volume of caustic alkali and pressing out the excess.  This treatment increases reactivity and produces cellulose derivatives of low viscosity.  Suitable halogenated olefines are 1-3-dibromo-2-butene, 1-bromo - 2 - chloro - 3 - butene, 1 - 2 - 3 - trichloro - 1 - propene, 1 - 3 - dichloro - 3 - phenyl - 2 - propene, 1 - 3 - 4 - tribromo - 2 - butene. Mixed ethers may be prepared by using mixed reagents, e.g. a mixture of ethyl chloride and 1-3-dichloro-2-butene.  The Specification as open to inspection under Sect. 91 comprises also the reaction of a cellulosic material with a halogenated olefine containing at least three carbon atoms and at least one other negative substituent.  Substituents mentioned in addition to halogen are phenyl, naphthyl, nitrile, carboxyl and carbethoxyl.  This subject-matter does not appear in the Specification as accepted.

Data storage.-A simple cell is shown in Fig. 1 in which two spaced electrodes 10 and 13 are placed in contact with a powdered electrophoretic material 16 suspended in a liquid. In response to the application of a field across the electrodes, e.g by means of a battery 17, the material 16 is deposited on one or other of the electrodes depending on the polarity of the voltage which may be determined by switch 18. The presence of the material 16 on an electrode causes the cell to exhibit rectification properties which may be detected. When the voltage is removed the material remains undisturbed and a second voltage is applied across the electrodes, e.g. by battery 19, to detect the rectification effect, the second voltage being of a magnitude insufficient to disperse the deposited material. In a practical embodiment each electrode plate consists of a plurality of parallel strips orthogonal to the strips on the other electrode so that by selecting one electrode strip on each plate an elementary storage location is provided in accordance with conventional matrix addressing techniques Display.-It is stated that by including at least one transparent electrode and by utilizing differently coloured liquid and powder or by using several different coloured powders each responsive to different voltage polarities a visible display may be produced. In an example a mixture of olive oil, benzene, polyoxyethylene sorbitan trioleate and TiO 2  powder is used.

Title: Method of and apparatus for comparing an object with a reference specimen
IPC: G06V10/88
Filed: 1977-08-25
Abstract: When monitoring the shape of workpieces, which are produced in series and cannot be positioned in a simple way, with reference to a pattern with the aid of a holographic correlator, either the workpiece or the holographic filter has to be rotated in order to obtain agreement between the orientation relative to the filter of the workpiece to be tested and that of the pattern relative to the filter. The invention provides for the workpieces (10) to be continuously guided through the test beam in a position which is arbitrary within certain limits. The spatial frequency spectra of the pattern are recorded on the holographic filter (12) for different positions relative to the filter. When the workpiece passes through the beam, the latter is deflected in such a way that its spatial frequency spectrum is successively compared with all the spectra on the filter. The centre of the correlation pattern is photoelectrically measured through a slit diaphragm (15). As a result, there is a substantial reduction in the requirement to position the workpieces accurately, and the testing rate is increased. <IMAGE>
