Abstract: A slicing machine has a blade having an edge, and a carriage adapted to carry a foodstuff to be sliced and displaceable past the blade edge in forward and reverse directions. A reversible drive on the support is connected to the carriage for displacing it in both directions. A sensor on the support generates an output when the foodstuff on the carriage is generally engaged by the blade edge. A controller connected between the sensor and the drive serves, on forward displacement of the carriage and foodstuff thereon, to forwardly displace the carriage and foodstuff thereon by the drive on generation of the output and subsequently, when the sensor means stops generating the output, displaces the carriage and the foodstuff thereon in the reverse direction by the drive.

Abstract: An apparatus for producing spun-bond webs has, beneath the receiving belt, a suction unit having at least two suction zones including a primary suction zone and at least one other suction zone, the primary suction zone receiving most of the filaments from an aerodynamic stretching unit below a spinneret. The suction speeds in the two zones can be adjusted independently of one another. Preferably three such zones are provided in succession in the direction of displacement of the perforated belt.

Abstract: A motor-vehicle bumper assembly has a transverse rigid and U-shaped rail having an inner wall closely juxtaposed in a normal motor-vehicle travel direction with a frame of a motor vehicle, an outer wall spaced farther from the frame than the inner wall, and a horizontal wall extending between the inner and outer walls. Two crush cans spaced transversely apart support the rail on the motor-vehicle frame. Each can has a first U-section element extending in the direction and having an inner end fixed to the frame and an outer end fixed to the inner rail wall and a second U-section element nested with and mostly vertically offset from the respective first element and having an inner end fixed to the frame and an outer end extending past the inner rail wall. An outer mounting plate is fixed to the second-element outer end and to the outer rail wall.

Abstract: The invention relates to a levelling bar for coking ovens, for levelling the cones of discharged coal which form under the filling holes of the oven chamber during the filling process. The levelling bar consists of two cheeks, such as plates (1), which extend essentially over the entire length of the ranged at a distance from each other depending on the width of the oven chamber, and parallel to each other. They are also interconnected and are essentially vertical. The levelling bar also has transversal coal carriers (2) which are arranged in the intermediate space delimited by the cheeks (1) at a mutual distance, one behind the other and which only extend over part of the cross-sectional surface of the levelling bar formed between he cheeks (1). The height (3) of the coal carriers (2), which take up the entire interval between the cheeks, is less than the height (H) of the cheeks (1) and the cheek form a gas channel (6) above the coal carriers (2) which is essentially free of built-in components.

Abstract: A drinking cup has sandwiched between an inner paper liner and an outer paper shell a ridge structure which has its ridges running peripherally, i.e. perpendicular to the axis, e.g. in the form of corrugations, a mesh or a cell network and can be partially filled with a phase-transition material to maintain a maximum temperature at the exterior of the shell for a given hot temperature of the liquid within the cup.

Abstract: A wheel chart having at least one rigid disk formed by a compact disk which, in addition to having a mirrored or reflective layer capable of carrying reproducible information, has legible matter on an obverse side which cooperates with a member such as a transparent rigid disk which can also bear indicia to enable calculations to be made by relative rotation of the disks.

Abstract: The invention relates to a method for tension levelling a cold-rolled strip, whereby the strip passes through a series of break rolls and a series of traction rolls and in the course of its extension is subjected to traction between the two series of rolls. The strip is bent under traction in a series of high-traction rolls, located between the brake roll and the traction roll series, in order to increase the degree of levelling. To achieve this, the series of high-traction rolls between the brake and the traction rolls has at least two traction rolls for generating the strip traction and bending operation.

Abstract: In prior art veneer-slicing machines, the blade is always mounted so that its cutting edge is parallel to the plane of the table, inside of which a wooden beam can be clamped. As a result, it is not possible or only possible with a high degree of complexity, to make adaptations to the shape of the wooden beam, said shape being, for example, conical in some types of wood, or to the course of the grain in order to achieve an optimal sectional image and thus the best possible veneer quality. The inventive veneer-slicing machine should make it possible to make simple adaptations to the shape of the wooden beam or should be able to influence the sectional image. To this end, the tool slide (1) can be placed at an angle (?) that is slanted with regard to the plane of the table (17).

Abstract: The invention concerns a method for producing a metal strip, whereby molten is continuously poured between two casting rolls (1, 2) of a strip casting machine with rolls. Above the molten bath (4) and respectively proximate to the molten bath (5) casting rolls (1, 2) transition surface a rotating magnetic field is produced which generates, in the molten metal, local turbulent flows, so that a surface current is formed in said molten metal, which surface current is directed by the casting rolls (1, 2) towards the central plane (E) of the molten bath (4), that is towards the plane for output of the metal strip (8), thereby enabling to largely prevent supernatant impurities at the surface of the molten bath and oxides located on the surface of the rolls from being deposited, and the molten metal particles from being prematurely solidified.
