Title: Process forthe preparation of chromium complex dyestuffs and cobalt complex dyestuffs
IPC: C09B45/01
Filed: 1977-02-09
Abstract: Chromium or cobalt complex dyes are obtained in a rapid reaction, without the need for an excess of metallizing reagent and, if desired, directly in the form of a ready-to-use solution or a liquid concentrate, if a metallizable dye is reacted with an anhydrous chromium or cobalt compound in ethers containing hydroxyl groups. By heating hydrated chromium or cobalt salts in this ether, an anhydrous metallizing reagent is obtained, which is very effective and is a solvato-complex of the salt employed; the metallization can thereafter be carried out advantageously with this reagent.

Title: Improvements in or relating to locks
IPC: E05B13/10
Filed: 1937-02-22
Abstract: 483,874. Door locks. VIRANY, G. Feb. 22, 1937, No. 5312. Convention date, Feb. 21, 1936. Addition to 458,341. [Class 44] A latch handle becomes freely rotatable upon its spindle when turned in a direction opposite to its usual opening movement and can only be recoupled to its spindle by a key. A handle 1 has a sleeve 3 containing a tumbler lock 4 enclosed in a cylinder 5 which is capable of axial movement along the lock. The cylinder 5 is held in place by four lock tumblers in openings 11, and is guided axially by a tongue 8. When the key is inserted, the tumblers are withdrawn thus releasing cylinder 5 which moves axially under the action of spring 9, and tooth 14 engages tooth 13 on the spindle so that movement of the handle will actuate the lock spindle. If the handle is turned in the opposite direction to its usual opening movement, the cylinder 5 is raised by one tooth 13 riding over the other 14, until at the outmost point the tumblers of the lock 4 snap into the corresponding openings 11. The latch cannot be retracted again until the key is reinserted and the cylinder 5 released. A pin 7 and slot 6 are provided to locate the cylinder 5 relative to the lock 4. The slots 15 opposite to slots 11 are so arranged that the lock tumblers may enter them whatever the position of the cylinder 5 so as to allow of their displacement as the key is withdrawn. One of the tumblers may be made conical so that shortly before the extreme point of contact of teeth 13 and 14 is reached, it moves the cylinder 5 still further away from the spindle of the handle. If for any reason it is required to make the movement of the cylinder 5 more than the distance between the tumblers, the latter and their openings are given different cross sections or positions such that the outer tumblers may slide over the openings they must first pass.

Abstract: 1482187 Labelling MONARCH MARKING SYSTEMS Inc 15 July 1974 [5 June 1974] 05432/77 Divided out of 1482186 Heading B8F Apparatus for printing and applying pressure sensitive labels from a supply roll of labels carried on a web of supporting material comprises a printing head and platen, a label delaminator, a web feed device downstream of the delaminator, and a web brake upstream of the delaminator, the brake being moved to an effective position by one of a pair of spaced abutments, and to an ineffective position by the other abutment. Fig. 3 shows a hand held label applicator, in which the label web passes from supply reel R over guide spring 310, past brake 270, round roller 323, over platen 174 and round delaminator edge 175 where a label 207 is released, and then the supporting web passes round rollers 178 and 293, over toothed feed wheel 171 and out of discharge passage Z2. Actuation of a finger lever 222 advances the print head 170 through gear sector 227 meshing with teeth 229 of gear 172 (see Fig. 10), which has further teeth 231 driving a rack on the print head. Return movement of the gears, effected by spring box 225, effects rotation of the feedwheel 171 through shaft 235, pawl mechanism 264, 253 and wheel 252 mounted on a support 246 by one way roller clutch 243 and connected to the feed wheel 171 by splines 258, 251. Gear teeth 227, 229, 231 and the print head rack include mutilated sections preventing incorrect assembly. The print head includes abutments 280, 281, Fig. 14, which at the extreme positions of the head move arm 272 of brake 270 between effective and ineffective positions, in which it is held by over-centre spring mechanism, so that the brake is released to allow web feed when the print head is advanced, and reapplied when the print head has returned. The brake is disposed so that tension in the web applies the brake more firmly. For threading up a new web, a member 288 is pulled manually, which removes roller 293 from the feed wheel, and shifts a brake abutment member 283 to a position spaced from the web path. The web is laid over the end of member 288, as in Fig. 3. The member 288 may then be returned manually to normal position, or be returned by a lost motion connection to pin 298 on the feed wheel, whereby the first few operations of the applicator will return the member. The brake supporting web may pass into a container 460, Fig. 27, in which it may coil up by itself, but positive winding up may be effected by the mechanism shown, comprising a base 466 rotatable about shaft 478 by a friction drive 486 from the supply reel holder, the web end being held by a finger 491 on the base.

Title: A method of preparing fluoride-free uranium dioxide
IPC: C01G43/025
Filed: 1958-02-24
Abstract: Fluoride-containing ammonium diuranate is thermally decomposed at above 400 DEG C. in nickel alloy equipment in a current of steam and hydrogen, which may be produced in situ by decomposition of ammonia, to form fluorine-free U3O8 which is further heated, preferably in an atmosphere of hydrogen, to form fluorine-free uranium dioxide.  One volume of hydrogen may be present per 10 volumes of steam in the first stage.  In the operation of the process, a solution containing UO2F2 and HF may be stirred under an ammonia atmosphere to precipitate ammonium diuranate or uranium hexafluoride may be hydrolysed with ammonia, and the precipitate after removal, but with or without washing, heated in a stream of a hydrogen-steam mixture. The subsequent reduction may be carried out in the same or a separate reactor.  In examples, the ammonium diuranate may first be heated in steam only at 850 DEG C. prior to a steam-hydrogen treatment at 700-850 DEG C.; a reduction with hydrogen at 700-900 DEG C. may be followed by further treatment with hydrogen at 950 DEG C.  The method is useful for the production of fluoride-free UO2 enriched in U235 for use as a reactor fuel.
