As described, the main bolt is spring- urged 8 to the locking position and is retracted against the spring by a follower 13 operated by a hand lever 14. A lever 25 is pivoted vertically and urged by a spring 29 to engage a projection 27 on the follower 13 and thereby hold the bolt 5 in the unlocking position until a lug 28, which is formed on the lever 25 and extends through the pLate 1, is depressed by contact with a door-frame. The locking unit 15 is of known pivoted lever type, the bolt 19 being spring urged to the extended position shown in Fig. 1, and locked only in that position. A hook lever 23 is sprung to engage a notch 24 in the bolt 19 and thus avoid shock to the bolt stump 20 and levers 21 when the bolt 19 moves to the extended position. The key used for withdrawing the bolt 19, or another key, may be adapted to align the levers 21 and disengage the hook lever 23 thus permitting the bolt 19 to extend to an extreme low position where it is again locked by the levers 21. A sprung lever 35 abuts the tail of the bolt 19 and thereby causes a disc 31 on the face-plate 1 to indicate the position of the bolt 19. The main bolt 5 is secured in the extended position by the entry of the bolt 19 into the aperture 10; the main bolt may be secured however, although not fully extended, by provision of a step 22 thereon which engages the bolt 19. The locking-unit 15 is mounted by screws 16 within the lock casing so as to be easily removed and replaced. In another embodiment, Figs. 10, 11 (not shown) the lug 28 on the lever 25 is replaced by a camming block projecting through the fore-end 2 and engaged by the edge of a door-frame.

Title: Improvements in or relating to the production of cellulose
Inventor: BATE STANLEY CHARLES
IPC: D21C3/00
Filed: 1949-05-27
Abstract: Cellulose is obtained from ligno-cellulose material by heating the material with a substantially anhydrous liquid mixture of a chlorinated lower fatty acid (i.e. one containing not more than 4 carbon atoms in the molecule) and an organic diluent which does not react with it.  Mono-, di-, or tri-chloracetic acid, or a mono- or di-chlorpropionic acid may be used.  The diluent may be chloroform, acetone, a hydrocarbon, particularly an aromatic hydrocarbon containing 8 carbon atoms, a normally liquid nitro- or halogenated aromatic hydrocarbon, a fatty acid containing 2-4 carbon atoms, or a fatty acid ester, e.g. ethyl acetate.  A diluent having a boiling-point above 110 DEG  C. is preferred.  It may be a xylene, ethyl benzene, nitrobenzene, chlorobenzene, acetic acid, propionic acid, ethyl valerate or isovalerate, or ethyl chloracetate.  A mixture containing 45-85 per cent by weight of chloracetic acid may be used at 120-150 DEG  C. for the treatment of wood.  At the end of the treatment the cellulose is freed from the treating liquid, e.g. by washing with an appropriate liquid.  It may then be subjected to a treatment with caustic alkali, sodium chlorite, or sodium hypochlorite. Chloracetic acid and diluent may be recovered from the used treating liquid and the first wash liquors by diluting with a large quantity of alcohol or water so as to precipitate the lignin and, after removal of the lignin, reconcentrating, e.g. by a solvent extraction method.  Alternatively the reagents may be recovered from the used liquids by a distillation method.  The treatment may be applied to spruce, larch, fir, poplar, beech, eucalyptus, and other woods, and to cereal straws and the residues of other annual plants. Specifications 640,490 and 679,832 are referred to.
