Abstract: A removable cover plate to be used in a threshing module of an agricultural machine, e.g., a grain harvester. The removable cover plate provides a uniform and homogeneous distribution of grains onto a cleaning and harvesting system of the machine. The removable cover plate is designed to be applied to at least one part of a concave of the cleaning and harvesting system of the machine. The cleaning and harvesting system includes at least one rotor and a least one concave mounted around the rotor, to which is attached and installed a removable structure that has a material retention surface, in which there are provided openings to limit grains and/or MOG passage.

Abstract: In a two chamber cartridge with chambers arranged axially one after the other, wherein the front chamber in a front part of the cartridge interior is divided by a double wall insert into an outer partial chamber and an inner partial chamber which are both closed at the rear ends by pistons and the rear chamber is formed by a beaker which is inserted into the rear of the cartridge and has a beaker bottom with a pin extending from the beaker bottom through an annular piston closing the beaker, the rear end of the double wall insert abuts the annular piston closing the beaker and the annular piston includes passages leading to gap between the two spaced walls of the double wall insert and the two front partial chambers and the intermediate space are in communication with a mouthpiece space at the front end of the cartridge.

Abstract: System for producing diffusion-inhibiting epitaxial semiconductor layers, by means of which thin diffusion-inhibiting, epitaxial semiconductor layers can be produced on large semiconductor substrates at a high throughput. The surfaces of the semiconductor substrates to be coated are first cleaned, and the substrates are then heated in a low pressure batch reactor to a first temperature (prebake temperature). The surfaces to be coated are next subjected to a hydrogen prebake operation at a first reactor pressure. In the next step the semiconductor substrates are heated in a low pressure hot or warm wall batch reactor to a second temperature (deposition temperature) lower than the first temperature, and after a condition of thermodynamic equilibrium is reached the diffusion-inhibiting semiconductor layers are deposited on the surfaces to be coated in a chemical gaseous deposition process (CVD) at a second reactor pressure higher than, equal to or lower than the first reactor pressure.

Abstract: In a cartridge closure with opening and closing means comprising a mouth piece with an open end and a closure part having a sleeve portion axially movably supported on the mouthpiece, a transverse wall is supported by support webs in axially spaced relationship from the open end of the mouthpiece and the closure part includes a neck portion of a smaller diameter than the sleeve portion with a transition area between the neck portion and the sleeve portion which includes a conical seal surface area which, in the closing position of the sleeve portion, sealingly engages a circumferential edge of the transverse wall.

Abstract: In a plastic injection anchoring sleeve having an essentially cylindrical sleeve body with a closed front end and an open opposite end for the insertion of an anchoring bolt, the sleeve wall has a plurality of openings closed by flaps which are formed integrally with the sleeve and pivotally supported thereby at their front ends, the flaps being provided with axially extending ribs projecting radially inwardly and having inclined front and rear end portions forming ramps for lifting the flaps outwardly and out of the openings when the sleeve body is removed axially from a molding core after injection molding, or when an anchor bolt is inserted into the sleeve body.

Abstract: A feeder is acted upon by opposing hydraulic drives and a spindle drive limits the advance. Hydraulic buffers are interposed either between the spindles and the feeder or between a carriage carrying the spindle drive and the machine bed. The buffer biasing force exceeds the force exerted by the feeder advance upon the feeder. The rate of buffer response is tracked separately.

Abstract: A hold down device is disclosed suitable for an edge planing machine for working sheet metal. The hold down device has a plurality of hold down elements arranged in the direction of movement of the sheet metal and in a laterally overlapping relation. A plurality of piston cylinder units are provided and a single hydraulic cylinder is associated with and connected to each element for pressing it down against the sheet metal to be worked. The lateral surfaces of the elements facing the plate edge are in alignment with each other. The piston rod of the hydraulic drives are connected to the middle of each element for swivel action. The individual elements may either have an essentially rhomboidal or Z-shaped plan view. A further improvement adds spring forces and guidance to the hold down action.
