Abstract: A controlled atmosphere broiler has a horizontal tunnel mounted on a frame and enclosing one run of a continuous, open-work conveyor traveling from an inlet end toward an outlet end. An air fan near the inlet end supplies air through a supply air duct to nozzles near the outlet end and discharging into the tunnel, both from above and from below, toward the conveyor. The supply air duct air is heated and provided with hot water vapor. The air is further heated by infrared heaters in the tunnel above and below the conveyor. Infrared radiation is reflected toward the conveyor by a reflector, preferably a common wall between the tunnel and the supply air duct. Air from the tunnel is aspirated through a return air duct by the fan. There is a damper control vent from the tunnel to the atmosphere, and air flow in the supply air duct is also controlled by a damper. The conveyor is supported by water-cooled cross tubes, and there is a drain pan below the conveyor.

A spring-loaded mass of distributing elements is arranged in a distribution space opposite the spraying means.

Abstract: Air intake for trash removal apparatus of a cane harvester. The air intake forms the lower portion of the housing of the trash removal apparatus and also serves to guide cane billets into the hopper of a pivotally-mounted billet discharge conveyor. The air intake is formed as a deflectible air permeable curtain of perforated rubber sheeting which avoids both damage to the air intake and jamming of the conveyor during use.

The carton, as envisioned, comprises first and second interior and diagonally arranged retaining walls. Each of the retaining walls is connected to and folded with respect to corresponding ones of the remote sidewalls. Each of the retaining walls may be formed with at least one article receiving compartment, such that whenever in a locked and assembled position each of the diagonal retaining walls is in opposed relation with respect to the other, and whenever in an unlocked position are enabled to automatically move apart from each other to thereby expose articles received within the compartments.

Abstract: A butt splicer for butt-joining a fresh web to an expiring web, which comprises two relatively displaceable clamping members and one intermediate clamping member, which determine for the two webs common and separate clamping paths. The two webs are cut simultaneously while being on their common paths, one web is cut while being on a separate path, and the two webs are taped together after the strip of said one web comprised between the two cuts has been removed. Butt control means preferably cause a slight separation of the corresponding web end edges before the web ends are taped together.

Abstract: Screening apparatus, particularly vibratory screening apparatus, includes a screening surface formed of one or more plates of flexible non-metallic material having apertures therethrough, with a plurality of attachment bars projecting from the underface of the or each plate at intervals along the length thereof. Each attachment bar extends across the width of the plate, and the plate or plates are supported by a support structure which includes a plurality of spaced support bars provided at intervals along their length corresponding to the intervals of the attachment bars with apertures of a shape to receive the attachment bars of the plate or plates.

Abstract: A sensing rod and two parallel guide rods project from the housing of a thread tension gage dimensioned to be carried in one hand and operated by pressure of one finger on a push-button which causes the threat-engaging end portions of the guide rods to advance into a common plane with the corresponding portion of the sensing rod. Further push-button movement causes the guide rods to wrap the tested thread over a portion of the sensing rod circumference, and the force of the tensioned thread deflects the sensing rod which is mounted on a torsion spring. The deflection of the sensing rod can be read from a scale calibrated in units of the thread tension.

Abstract: Mirrors with a variable focal distance composed of a disc of revolution about an axis having a reflecting surface. Said disc has a variable thickness and is bent elastically by applying thereto a distributed load or an axial load and by balancing this load by a central or peripheral bearing pressure. The deformation obtained is parobolic provided that the variable thickness of the disc varies as a function of the radius from the axis.One application of the present invention is the manufacture of mirrors with a variable focal distance.

Abstract: In a method of measuring a pressure of a suspension, for example, slush, wing through a suspension conduit, in which the pressure is transferred through a water-filled sensing duct, whose nozzle opening out in the suspension conduit is rinsed with water, to a pressure pick-up whose output signal is fed to recording and/or display apparatus, the sensing duct and/or the nozzle may become clogged, for example, by the deposition of algae of the rinsing water or the deposition of solid substance from the suspension.In order to render the measurements more reliable the pressure is detected in a sensing zone withdrawn out of the suspension stream, where the risk of deposition of solid substances is limited, while the pressure is detected in consecutive measuring cycles, each including a rinsing phase and a pick-up phase of longer duration than the rinsing phase.

Abstract: A cutter mechanism for use in a tufting machine or the like featuring a stationary blade having openings through which yarn strands project, the stationary blade being positioned in the path of travel of yarn strands from yarn creels to bit-applying elements with the cutter mechanism further featuring a series of reciprocable blades which are biased against the stationary blade whereupon reciprocation the reciprocable blades will pass over the openings and because of their biasing effect, penetrate the plane of the stationary blade passing into the openings thereby severing the yarn strands.

Abstract: A method and apparatus suited for forming radiographs wherein distribution patterns of penetrating radiation representing radiographic information to be recorded are recorded in terms of electrostatic charge patterns on successive charge-receiving areas distributed along a carrier, by bringing such areas successively into a chamber in which each such area is exposed to an ionizable fluid while this is exposed in an electric field to a pattern of penetrating radiation thus producing in such fluid positive and negative charge carriers and forming with the positive or negative charge carriers a corresponding electrostatic charge pattern on such area, the latter being brought by subsequent movement of the carrier to a position outside such chamber where such electrostatic charge pattern is transferable or developable to form a transferable visible record.
