Title: Pattern mechanism for knitting machines
IPC: D04B15/66
Filed: 1972-01-26
Abstract: A pattern multiplier to reduce the number of plain links of the chain on a circular knitting machine wherein main and auxiliary ratchets intermittently advance the chain sprocket with the main ratchet advancing the chain greater distances when chain controls of the knitting are required and with the auxiliary ratchet advancing the chain lesser distances when no controls of the knitting are required. The angular pitch of the teeth of the main ratchet is twice that of the teeth of the auxiliary ratchet so the former advances the chain twice the distance of the advance by the latter. Cams on the chain, via a flexible cable, act to raise the main pawl out of action thereby permitting the auxiliary pawl and auxiliary ratchet to continue the advance of the chain.

Title: Walking beam furnace
IPC: C21D1/00
Filed: 1972-10-31
Abstract: The improvement in top and bottom-fired walking beam furnaces wherein the lower burners, like the top ones, fire opposite to the direction of travel of the work pieces from the charging to the discharge end of the furnace. This is accomplished by the use of a plurality of parallel walking beam assemblies, each of which has two spaced stationary water-cooled beam sections having a supporting rail along the top. The bottoms of these side pieces are rigidly integrated through a bottom water-cooled beam section. There is an idler beam section supported for longitudinal motion above the bottom beam section, longitudinal travel of which in one direction raises the idler section and in the opposite direction lowers it. There is a longitudinally-movable traversing beam section having a load-traversing rail at its top which is lifted above the support rails on the side beam members when the idler beam raises, but which is normally lower than the support rails. After the traversing beam is raised it is moved longitudinally toward the discharge end of the furnace and when it is lowered it is returned to its normal position. Combined tie rods and spacers at intervals along the assembly connect the upper portions of the side beam sections so that the girder is in effect a box section within which are the walking beam elements. Mechanism outside the furnace at one end moves the idler beam section and at the opposite end moves the traversing beam member, and each holds its beam against endwise travel when the other is moving.

Title: Device for cooling a longitudinally moving elongated product.
IPC: C21D9/573
Filed: 1980-01-18
Abstract: An apparatus for cooling an elongated product during its movement through the apparatus comprises an elongated tube having a cooling fluid inlet at one end and a cooling fluid outlet at the other end so that the cooling fluid will flow from the one to the other end through the tube.

Patent ES-8202426-A1 (ES)
Title: Measuring apparatus for detecting feed strength of bulk material flow
IPC: G01F1/30
Filed: 1980-11-12
Abstract: In the case of a measuring device having a guiding device with an outlet opposite a measuring surface (baffle plate) which deflects a stream of bulk material and detects horizontal force components, the frictional forces on the measuring surface and the impact shock of the stream of bulk material striking the measuring surface need to be kept low. This is achieved in that the guiding device is composed of a guide chute (6) to which the free-falling bulk material (4) can be fed, furthermore that the guide chute (6) is steeply inclined in its upper part and less steeply inclined in its lower part, so that it receives the stream (4) of bulk material with as little impact shock as possible and deflects it obliquely downwards to the measuring surface (1, 9) and that the measuring surface (1, 9) is essentially arranged in a vertical plane, so that the stream (4) of bulk material coming from the guide chute (6) strikes the said measuring surface (1, 9) at an acute angle. An arrangement of this type eliminates friction and impact shocks on the measuring surface to a substantial extent, so that such effects do not influence the measuring result.
