Abstract: 768,625. Multiple fastenings. ERISMANN, P. April 22, 1955 [April 23, 1954], No. 11762/55. Class 44. In a chest-of-drawers or the like having a plurality of slidably arranged drawers 11, each of the drawers is provided with a swingable locking hook 14 adapted to engage a locking member 20 which is common to the plurality of drawers in order to lock the drawer in its closed position by such engagement, the common locking member being rotatable about such an axis that on its rotation into its unlocking position its locking surface 38 adapted to cooperate with the noses 16 of the locking hooks passes from a position at right angles to the sliding direction of the drawers to a position at such an angle to said direction that the locking surface 38 is lifted off the co-operating surfaces 39 of the hook noses and causes the looking hook of each drawer to slide from the locking surface 38 when the drawer is drawn to open it. As shown, the locking member is square in cross-section and from its locking position it is rotated anticlockwise through an angle of 45 degrees to its unlocking position so that only the tip of each hook 14 is in engagement with the locking surface 38. Each hook 14 is loaded by a spring 18 to its locking position and has an extension 17 which can abut against the rear face of the drawer 11 to limit rotation of the hook in its locking direction. The rear face 19 of each hook is tapered so that when the drawer is closed the hook is rotated against the pressure of its spring 18 by the engagement of the face 19 with the locking member so that in the fully closed position of the drawer it can snap behind the locking member. The movement of the hook takes place whether the locking member is in its locking or unlocking position. The locking member is rotated from the front of the chestof-drawers or the like by linkage and it is mounted on a pair of pins attached to the top and bottom of the chest or the like. The top pin is longer than the bottom pin and the arrangement is such that the locking member can be engaged with the top pin first and then by moving it downwardly with the bottom pin. It is retained in position by a cotter-pin fitting in a cross-bore in the top pin.

Title: Improvements in the manufacture of highly polymeric polymethylene terephthalates
Inventor: FLETCHER NORMAN
IPC: C08G63/86
Filed: 1953-04-30
Abstract: In the preparation of highly polymeric polymethylene terephthalates a bis(omega-hydroxy-n-alkyl)terephthalate is polycondensed in presense of manganous acetate as a catalyst. The bis(omega hydroxy-n-alkyl) terephthalate may be formed from a glycol and a di-alkyl terephthalate by ester interchange, using manganous acetate also as catalyst in the initial step.  Other catalysts may be used with the manganous acetate in the ester interchange or polycondensation steps. Suitable auxiliary polycondensation catalysts are antimony compounds, e.g. antimony salts especially the acetate, double salts such as potassium antimonyl tartrate, or salts of antimony acids, e.g. potassium pyrantimonate.  Antimony oxide may also be used.  Examples describe the preparation of polymers from ethylene glycol and dimethyl terephthalates using as catalysts (1) and (2) manganous acetate, (3) and (4) manganous acetate and antimony trioxide. Titanium dioxide is added during the polycondensation step in example (3).

Title: Improvements in or relating to granulation processes
Inventor: GARRETT KEITH HENRY
IPC: B01J2/12
Filed: 1962-03-28
Abstract: 992,237. Granulation process. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. March 22, 1963 [March 28, 1962; Nov. 8, 1962], Nos. 11975/62 and 42231/62. Heading B5A. A process for converting powder into high density spheroidal granules comprises forming a powder into a plurality of salt agglomerates of paste consistency and rolling the agglomerates on the interior walls of a drum of circular crosssection while simultaneously pressing the agglomerates against the walls by centrifugal forces greater than gravity. In the embodiment shown in Fig. 3, the drum 1 is of cylindrical shape and has its interior shaped into seven shallow troughs 2A-2G, each trough being crossed by raised spiral bands 3A-3G. Preformed agglomerates of irregular shape and dry powder are fed into the drum from feed tubes 40, 36, respectively. The drum is held tightly by metal bands 17, 24 which are rigidly attached to arms (not shown) extending outwardly from the plane of the paper, which are pivotally connected to links which are themselves pivoted to frame 31. The drum then executes a slight oscillatory motion with respect to the pivotal connection to the links. Journals 25, 26 are rotatably mounted on a shaft 50 connected by cranks 27, 28 to shafts 29, 30 rotatably mounted on the frame 31. Rubber belts 21, 21<SP>1</SP> transmit drive from an electric motor to wheels 6, 6<SP>1</SP>. The formed granules are then removed from the drum via tube 41. In a bath process (Fig. 2, not shown) a pot-shaped drum is used which is rotated and is connected to a rod which slides in a head pivotally mounted on the base outside the area enclosed by the locus of the moving centre of the drum. Suitable materials include metals, metal oxides, metal carbides and ceramic materials in general. The pasty agglomerates are formed by mixing the powder with 4-12% by weight of a binder, preferably an alcohol having more than 6 atoms. As binder is squeezed out, more powder is added to prevent the granules sticking together. Granules of UO 2 -PuO 2  having density 6.8 gm./c.c. and sizes 300-700 microns may be produced which are suitable for use as nuclear fuel.

Title: Improvements in or relating to filling machines
IPC: B65B1/36
Filed: 1940-09-06
Abstract: 605,856. Packeting; delivering means and quantities. RAYMER, M. M. Sept. 6, 1940, No. 12396/42. Convention date. March 6, 1940. Divided out of 605,855. [Class 94(i)] [Also in Group XXX] Relates to a machine for filling containers with fluent material such as the machine described in Specification 605,855, in which the material is delivered to the container from a hopper by a compartmented member rotating step-bystep. According to the invention, the member is rotated by a Geneva mechanism to prevent shock in starting and stopping. The hopper consists of a cylindrical drum 130, Fig. 1, divided transversely by a partition and terminating in two spouts 16. Within the drum is a four-bladed paddle wheel 134 forming a compartmented structure which is rotated by a sprocket wheel 136 driven by a Geneva wheel 142, Figs. 1 and 2. The wheel is provided on one face with four raised portions 144 between which are radial slots 145. A radial arm 157, mounted on a driving shaft 6, is provided with a roller 158 which, during the rotation, engages one of the slots 145 and turns the wheel 142 through a right angle. During the period when the wheel 142 is stationary, it is locked against rotation by a pivoted dog 154 which engages a slot 146 in the edge of the wheel. A cam 149 on the shaft 6 moves the dog out of engagement with the wheel 142 before the wheel commences to turn, and allows it to engage a slot 146 when rotation of the wheel ceases.
