Abstract: A bread molder for working dough between convergent runs of driven endless roller-mounted upper and lower belts has the lower belt carried by an adjustment frame which can be moved to vary the spacing between the two belts. A pair of side shaping arms can be inserted closely between the two belts to limit the lateral expansion of the dough being worked. A delivery plate on the belt adjustment frame extends below the upper belt to receive and deliver a dough piece worked between the two belts, and a series of spaced parallel splitter blades are mounted for simultaneous advance between divisions in the delivery plate for dividing the worked dough into sections.

Abstract: A plurality of fluent substances are combined in a distributor (11, 37) and caused to flow in a continuous, pressurized stream through a mixing zone (13, 13', 57) wherein the substances are intimately mixed by turbulent dispersion effected by a series of conically shaped surfaces (24, 27; 62, 64) and alternate restrictions (25, 63) and expansion chambers (28, 65). While various fluent substances may be advantageously mixed, a typical utility is for effecting a thorough air binding of ink particles to attain efficient foaming (29) in the deinking of reconstituted printed paper slurry.

Abstract: A clamp for long-handle floor-washing wipers or scrub-brushes, which comprise an elongated head for a wiper blade or brush carried at the end of a broomstick, the clamp being adapted to releasably hold a rag and prevent its slipping-off the head during use. The clamp is comprised of two springy arms, spaced from each other and extending in alignment in a common plane, and a frame holding the arms by the respective extreme, outer ends thereof. The distance between the inner, free ends of the arms is slightly less than the diameter of the stick. When the clamp is mounted, with the stick squeezed between the free ends of the arms, the arms become flexed, thereby displacing the frame into either an engaging or a disengaging position with respect to the wiper head.

Abstract: The intake space of a centrifuge drum is divided into a vestibule with ribs and an intake chamber without ribs. The vestibule communicates with the intake chamber through an annular gap between the outside diameter of a disk secured to an intake pipe and the inside diameter of the intake space. The intake chamber communicates with a set of disks through channels. The diameter D.sub.K of the intake chamber at the level of the channels is longer than the diameter D.sub.F that must be maintained at the upper surface of the centrifugate in a skimming chamber during operation. Since the incoming centrifugate does not rotate in the intake chamber and since no rotational pressure is accordingly generated, the intake pressure in the intake pipe is transmitted when the intake chamber is full to the centrifugate in the intake chamber, until the requisite level of centrifugate in the skimming chamber is attained.

Abstract: An apparatus for selectively feeding tape having label patterns printed on it at one of two different speeds to maintain alignment of the label patterns with a downstream device such as a cutter for severing the tape between label patterns. Marks on the tape associated with the individual label patterns are monitored by a sensor to detect misalignment of the tape. The tape is fed between a driven feed drum and a spring biased pressure drum. The feed drum is mounted on a main shaft. A drive shaft extends parallel to the main shaft. A pair of gears are mounted on each of the shafts and each gear meshes with one of the gears on the other shaft to form two separate power transmission paths. The sizes of the gears are selected so that the gear ratios of the two power transmission paths are different. The gears on the main shaft are selectively fixed to the main shaft for rotation with it by electromagnetic clutches controlled by the sensor.

Abstract: A centrifuge apparatus having an adjustable weir surface for adjusting the depth of an annular pool of a light and heavy phase material mixture therein. A first annular plate is positioned over a discharge outlet and includes a plurality of notches, each defining a generally arcuate opening and in the periphery thereof. A second annular plate is positioned in coaxial parallel juxtaposition with said first annular plate and also includes an identical amount of notches, each defining a generally arcuate opening. The annular plates are angularly positioned with respect to each other such that the generally arcuate openings are placed in overlapping relationship. Therefore, depending upon the relative angular position of the annular plates with respect to each other, the weir length can be increased and decreased.
