Title: Improvements in or relating to the processing of plastic materials
IPC: B29C48/03
Filed: 1953-07-10
Abstract: 741,695. Mixing and kneading appliances. AETNA-STANDARD ENGINEERING CO. July 10, 1953 [Jan. 7, 1953], No. 19221/53. Class 86. [Also in Group XXX] A mill for working plastic material consists of a pair of rotating rolls, one of which is a work roll about which the material forms as a sheet, a knife to slit the sheet and means to coil an edge of the sheet upon itself comprising a coiling roller rotatable about an axis extending substantially radially of the work roll and having a working face opposed to the surface of the work mill. In a mill for working rubber or synthetic resins consisting of a lower or feed roll 4, Figs 4 and 15, and an upper or work roll 5, the stock to be milled is supplied at a measured rate to the feed roll 4 at the feed end, at which there may be a plurality of longitudinal grooves 6, and then forms about the work roll 5 as a sheet which moves axially along the roll 5 towards the end remote from the feed end. A plough 32 close to the edge of the roll 5 at the feed end, starts a coiling operation on the edge of the sheet as it moves upwardly from the bight B and the resulting coil is fed between the roll 5 and a coiling roller 35 directly above and slightly spaced from the roll 5, which coiling roller is rotated to cause the sheet to coil upon itself a number of times. From the coiling roller 35 the coil passes to a main coiling roller 36, similar to but larger than the roller 35, and from the coiling roller 36 the coil passes into the bight B. Spaced along the roll 5 are knives 85, Fig. 14, which slit the sheet near the top of the roll 5 to form edges, which are given initial coiling movements by ploughs 98, 99, the resulting coils being fed beneath further main coiling rollers 37-40 and then into the bight B. At the end of the roll 5 remote from the feed end, a plough 42 and coiling roller 41 form the sheet into a coil which is stripped from the roll 5 by a stripping plate 135, and withdrawn, if necessary, by a hugger belt take-off mechanism, (see Group XXX.) Dams or baffles, Fig. 5 (not shown), project into the bight B between each pair of coiling rollers to prevent material from migrating along the bank in the bight B. The coiling rollers, which have a flat central working surface and a bevelled edge portion may be freely rotatable, or may be positively driven so that the speed of the bevelled edge portion is comparable to or slightly faster than the surface speed of the work roll 5, and the coiling rollers may be angularly and axially adjustable and axially yieldable. The feed and work rolls 4 and 5 are cored for the circulation of heating or cooling water.

Title: An improved wheeled gun carriage having trails pivoted to the carriage head
IPC: F41A23/32
Filed: 1921-07-18
Abstract: 169,418. Schneider et Cie. June 11, 1921, [Convention date]. Addition to 167,450. Field carriages.-Relates to field carriages of the kind described in the parent Specification in which bent portions B of the twin trails A are longitudinally pivoted in the carriage head D and cross-connected by linkage so that on uneven ground the lowering of the spade end of one trail automatically produces an equal rise in the corresponding end of the other, the trails being also brought together for transport by rotation on the longitudinal pivots. The present invention comprises various constructions of the linkage for cross-connecting the trails. In the construction shown in Fig. 3, arms H fast with the pivots B bear against projections f on toothed sectors loosely mounted on the pivots and geared to a common pinion G rotatable on the carriage head. When setting up the carriage or when firing on uneven ground, a downward movement of one of the arms H produces an equal rise of the other, but the arms H move away from the projections f when the trails are brought together for transport. In modifications the toothed sectors are replaced by chain-and-sprocket gear or by hydraulic pistons working in a cylinder full of liquid. Fig. 9 shows arms K on the pivots B cross-connected by a link L. The pivots B which engage the arms K by square shanks B<1> are, after raising locking-collars M from grooves B<3>, drawn rearwards to the position shown in Fig. 13 to permit of rotating the trails into the transport position. After rotation of the trails the collars M spring into recesses b<2> and the trails are locked in the transport position by the pins N which secure the collars.
