A method is provided for producing a molded part that is deep drawn from a thermoplastic foil. An outer surface of the thermoplastic foil is provided with a positive depth structure, under the effect of heat and pressure, by means of a stamping or embossing roller that has a negative depth structure. In at least one extent of a surface of the embossing roller, the negative depth structure of the roller is compressed in such surface regions thereof that effect a stretching of the foil during deep drawing. Subsequently, at least a portion of the foil is deep drawn.

A method is provided for converting feedwater to fresh water utilizing existing water pressures and high flow rates. At least one reverse osmosis unit is disposed in a feedwater supply conduit. Feedwater is conveyed through the supply conduit and the reverse osmosis unit at a pressure that exceeds the osmotic pressure for solids dissolved in the feedwater. A first stream of fresh water is withdrawn from the reverse osmosis unit as permeate, and a second stream is withdrawn therefrom as effluent. The effluent is returned to, or continues to flow in, the supply conduit downstream of the reverse osmosis unit.

A tool head of a trimmer is provided, and has a gear mechanism housing and a rotatably drivable tool shaft that is mounted in the housing. Held upon the tool shaft is a hub portion that rotates with the tool shaft. On that side that faces the hub portion, the tool head is provided with at least one stripping edge, which has a radial component that extends from the inside to the outside, and which projects beyond the contour of the hub portion.

A securement arrangement for a seat belt closure of a three-point seat belt system in a vehicle comprises an anchor piece secured to the vehicle, a closure body, and a generally U-shaped closure body retaining assembly for mounting the closure body on the anchor piece. A spring disposed between a pair of U-forming legs of the closure body retaining assembly biases the closure body into its home position. A contact element emits a signal to be processed by an onboard signal processing unit when the closure body, due to the application thereto of a load imposed by the seat belt, is displaced so as to overcome the biasing force of the spring. The contact element correspondingly moves out of contact and emits a signal in response to its movement out of contact.

A method is provided for producing a cylinder in a two-cycle engine. The cylinder bore is first machined as a preparation for the provision of a coating. The thereby resulting window edges that surround an inlet window are then at least partially chamfered. The cylinder bore is consequently provided with the coating, which at least partially overlaps the chamfered window edge. There thereby results in the region of the window edge a location of least spacing relative to the axis of the transfer channel. The piston liner or gliding surface is finally machined to a finished dimension such that in the region of the chamfered and coated window edge or corner there is formed a coating edge having a wall spacing relative to the location of least spacing, which such wall spacing having a maximum value of 0.7 mm.

In order to achieve temperature distribution, in particular a homogeneous temperature distribution in, for example, a substrate during a thermal treatment process of said substrate, a method is disclosed for the thermal treatment of substrates, in particular semi-conductor wafers, in a process chamber comprising at least one temperature distribution influencing element located in the process chamber. During thermal treatment, the spatial arrangement of the element is altered relative to the substrate and/or to the process chamber. A device for the thermal treatment of substrates in a process chamber is also disclosed, comprising at least one temperature distribution influencing element located in a process chamber wherein a device is provided in order to alter the spatial arrangement of the element relative to the substrate and/or to the process chamber during the thermal treatment process.

A series of fabricated products for electrically rotatably driven machines, especially alternating current motors for attachment on drives, for alternating current motors having various pole configurations and operable in differing performance classes, voltage classes, and frequency classes, includes a plurality of trunk motors each having a motor housing, a motor terminal box for the provision of electrical current to stator windings mounted in a rotationally symmetrical manner in the motor housing, and a rotor. The rotor has a shaft supported on a bearing bracket. The trunk motor also includes a drive side, a non-drive side, and a shaft end extending outwardly from the non-drive side adapted for the securement thereto of a plurality of differing attachment shafts.

A two-cycle engine is provided and has a cylinder with a combustion chamber delimited by a reciprocating piston. The engine has an inlet for fuel/air mixture, an outlet out of the combustion chamber for exhaust gas, and four transfer channels that open into the cylinder via inlet windows, and fluidically connect the crankcase with the combustion chamber as a function of the piston position. The transfer channels have a connecting portion to the crankcase, an ascending portion substantially parallel to the longitudinal axis of the cylinder, and an opening-out portion into the combustion chamber. The planes defined by that side wall of the transfer channel close to the outlet that is remote from the outlet, and by the side wall of the transfer channel remote from the outlet that is close to the outlet, intersect in a line extending on the side of the mirror plane facing the transfer channels.
