Title: Intermittent tape feed
Inventor: MASON RALPH ALLEN
IPC: G11B15/56
Filed: 1964-11-06
Abstract: 1,031,238. Apparatus for monitoring continuous length of material. CREED & CO. Ltd. Nov. 6, 1964, No.45305/64. Heading G1M. Apparatus for monitoring a continuous length of material 3 between a supply 1 and a utilization device 2 includes an electromagnetic brake 7-13; operative to arrest release of the tape in the supply thereof to the loop 30; a plurality of loop forming rollers 15-17, one roller being operative through a sensing member 18 to move in one or other of two directions dependent respectively on an increase or decrease in the amount of tape in the loop; and electrical switch means 23 operative by the sensing member 18 in alternating movements thereof in the one direction and the other direction and inhibit application of an energizing current to an electromagnetic brake which thereupon alternately arrests and releases the tape. Tape 3 is fed in from a store 1 through rollers 4, 5 mounted on a frame 6, and through an electromagnetic brake device including jaws 13, 8 actuated by a spring-loaded head 12. The tape then passes over rollers 15, 16, 17 to the tape utilization device 2. Roller 17 is connected through the pivoted sensing means to generate microswitches 20, 23. When the loop is at its maximum, operation of microswitch 23 causes coil 9 to be de-energized whereby the tape is gripped by jaws 8, 13 to cause cessation of the tape. As the utilization device 2 draws tape from the loop, the loop size decreases pivoting a member 18 to release microswitch 23, causing subsequent release of the brake. Thus the infeed of the tape is intermittent. If there is an obstruction in the infeed of the tape, the loop size decreases until microswitch 20 is actuated to stop the motor withdrawing the tape. The device may be used for teleprinting.

Abstract: 1,201,076. Racks. INTERLAKE STEEL CORP. 9 Oct., 1967, No. 46039/67. Heading A4B. In a pallet rack an L-section end plate 4, welded to a beam 2, has two rearwardlyprojecting studs 5 for engagement in keyhole apertures 3a or 3b in an upright to connect the beam to either side of the upright, the studs being spaced at a distance equal to the distance between every third keyhole 3a or 3b and the end plate being reversible. A detachable locking arm 7 consisting of a spring metal strip has a headed pin 8 and a pin 9 which engage, respectively, in narrow portion 6b and enlarged portion 6a of keyhole aperture 6 in the end plate, the pin 9 also engaging in the enlargement of the intermediate aperture 3a or 3b. The locking arm is also reversible but can be assembled properly in only one position relatively to the end plate and when improperly assembled projects due to non-alignment of the pin 9 with the enlargement of a keyhole aperture 3a or 3b so that visual warning is given that the beam is not locked to the upright. In modifications, the upright has a single row of apertures each of which has a wider upper end positioned vertically above a narrower lower end, or the headed studs are spaced from each other at a distance equal to the distance between every fourth keyhole aperture so that the locking arm is reversible and properly lockable in both positions. The beam may be a cantilevertype support secured to an upright at only one end.

Abstract: 1,135,258. Waveguide couplings. LITTON INDUSTRIES Inc. 14 Oct., 1966 [17 Nov., 1965], No. 46184/66. Heading H1W. A coupling arrangement for waveguides, particularly flexible waveguides, comprises means for clamping the edges of the waveguide to a detachable flange. As shown, the corners of a corrugated, rectangular waveguide 10 are cut away at the end of the waveguide and each of the four marginal portions 24 is bent outwardly to lie in a plane forming an acute angle with the axis of the waveguide. These portions are clamped between complementary surfaces 18, 28 respectively on a flange member 13 and a clamping member 14. The waveguide 10 may be provided with a sheath of flexible material (not shown) and the end portion of this sheath may extend either within or around a sleeve 34 integral with the clamping member 14. In the latter case, the sheath is clamped to the sleeve by means of a band clamp (not shown) positioned just beyond a circumferential ridge 36. A sealing ring 44 may be inserted between the flange and the clamping members. The flange may be bolted to the flange of a further waveguide or may be provided with clamping members on both sides (Fig. 4, not shown).

Abstract: 1,042,017. Valves. ENGLISH ELECTRIC CO. Ltd. Dec. 28, 1962 [Dec. 28, 1961], No. 46398/61. Heading F2V. [Also in Division G6] Apparatus for removing spent fuel elements from a nuclear reactor containing reactor coolant gas under pressure comprises a duct 73 (Fig. 5, not shown), provided with independently operable valves 71, 72, into which the fuel element is lowered with valve 72 closed and from which it is subsequently removed on to a vertical conveyer 75 after closing valve 71 and blowing out the gas to the effluent system of the reactor. Two portions 10, 11 of the gas duct are valved by a port 24 in a plate 22 bolted to a ring 18 which is rotatable upon ball bearings 19 within a valve housing chamber 15 which is defined by circular plates 12 and 13 bolted together and mounted eccentrically with respect to the gas duct. The ring 18 is rotated from pinion 25, engaging teeth 18a around its inner periphery, which is driven from motor 29 through gear-box 28 and friction clutch 27 and which may also be rotated by an emergency hand wheel (not shown). The valve plate 22 is halted against fixed stops 30, 31 upon plate 13 (Fig. 2, not shown) and, in these positions, actuates micro-switches 36 or 35 for indicating or motor controlling means. Sealing is effected around the periphery of the plates 13, 12 and around the duct between the plates and flanges 10a, 11a by natural or synthetic rubber rings 38. Greased rubber or synthetic rubber rings 39 of circular section retained within dovetail groove 40 effect sealing between one or both of the fixed plates 12 and 13 and the moving plates 22. Each pair of sealing rings 38 and 39 is connected by ducts 41 which detect and transmit pressure differences across an orifice 42 which arise from gas leakage to operate a differential pressure warning switch 43. In an alternative embodiment, the sealing action is obtained by linear displacement of a similarly sealed plate actuated by rack and pinion.

Filed: 1963-12-11
Abstract: A dihydroperoxide is produced in the form of its solution in aqueous alkali by oxidizing a dialkyl aromatic hydrocarbon of the general formula <FORM:0982515/C2/1> in which Ar is an arylene group and R1, R2, R3 and R4 are alkyl groups with molecular oxygen and with addition of alkali, subjecting the oxidate to treatment for the removal of alkali metal salts contained therein until the oxidate contains salts in an amount less than the equivalent of 0.1 gram of alkali metal per kilogram of oxidate, extracting the treated oxidate with aqueous alkali solution to recover the dihydroperoxide, separating the resulting aqueous phase containing the dihydroperoxide from the organic phase, and recycling the organic phase to the oxidation.  The preferred starting material is m-diisopropylbenzene. The oxidation may be effected with air, at a pH within the range of 3 to 7.  The removal of alkali metal salt from the oxidate may be carried out by mechanical separation, such as filtration or in a centrifuge, or by washing with water. The mechanical separation may be combined with a water wash. After removal of the salts, the oxidate is contacted with an aqueous solution of an alkali, preferably containing from 1% to 12% of alkali, e.g. sodium hydroxide, to extract the dihydroperoxide. The aqueous phase may be separated from the organic phase using a centrifuge and the organic phase is recycled to the oxidation reactor.  A detailed example is given.

In the colour television tube of Fig. 2, the back panel and set of vanes 30 constitute a source of electron sheet beams, the back panel being of metal or conductively coated glass, and being further coated with MgO or BeO, which emit electrons when impacted by ions resulting from the ionization of the residual gas in the device. Emitted electrons are multiplied by dynodes 40 formed on the vanes 30, the device being initially primed by the incidence of stray, e.g. cosmic, radiation, and thereafter being self-sustaining for as long as suitable potentials are impressed upon the dynodes. The number of multiplier vanes 30, which may be spaced 0À76 mm. apart, is related to the number of scan lines employed in the television system, the vanes 32 bearing accelerating, focusing, and modulating electrodes 36, to which latter the video signal is applied to control incidence of the beam electrons on the colour phosphor strips 24, 26, and 28.
