Abstract: An easy openable closure device for a packaging container, comprising an outer layer (11), for instance injection moulded of plastics, and an inner layer possibly comprising several sublayers and such that it gives the closure device a specific characteristics as to for instance welding possibilities, gas barrier and light barrier. 
     A first tearing denotation (20) is arranged in the outer layer and merges into a second tearing denotation (15) under a tan­gentially acute angle, said second denotation extending circum­ferentially around the closure device. 
     At both sides of the circumferential tearing denotation (15), the inner layer (12) is sealed to or connected to the outer layer (11). 
     In the outer layer there is arranged an element (17) having a portion (18) for penetrating the first tearing denotation (20) in the outer layer inside the said sealing region (16, 16′). 
     The strength of the second tearing denotation (15) is lower than the sealing strength between the layers and the latter strength is higher than the tearing strength of the inner layer.

Abstract: In an ignition map-based control of an internal-combustion engine, knocking should be avoided even in the case of a sudden change of the load or rotational speed. For this purpose, a correction value in the "retarded" direction is superimposed on the ignition timing determined from the ignition map, the amount of said correction value being dependent both on the intake air temperature and on the engine speed. After the retardation has been performed, the correction value is adjusted in the "advanced" direction within a selectable time until the instantaneously valid ignition timing from the ignition map is reached again.

Abstract: A communication channel is established between a master station (2) and one of plural remote stations (1A,...1H) in a multichannel access (MCA) cordless telephone system. Access data is transmitted from the master station (2) to all of the remote stations (1A,...1H), at the same time, to designate a selected remote station as a representative station. The access data also includes calling data which seeks a response from that representative station. In the absence of a response to the calling data from the previously designated represen­tative station, the station identifying data is changed to designate a new remote station as the representative station. The foregoing process is repeated until a representative station responds to the calling data, whereupon the remote stations (1A,...1H) are polled, in sequence; and a communi­cation channel is established between the master station (2) and the particular polled station which replies to the polling operation.

Abstract: In a navigation system and method for guide-wire-less guidance of driverless floor conveyors of any wheel configuration, navigation interpolation points (P) are arranged in a linear formation chain along a reference track (19), the regular and/or irregular intervals of which points are a multiple of the vehicle wheelbase (22). The navigation interpolation points (P) are constructed as active and/or passive data carriers of an identification system and are embedded in the roadway surface (3). Nominal path curves and coordinates of the navigation interpolation points (P) are stored inside the vehicle as a geometry data set in a spatially fixed coordinate system (x,y, gamma ) and the absolute angular position  gamma  of the floor conveyor (1) is measured by means of vehicle-internal magnetostrictive sensors (2) using a distance measurement between the longitudinal axis of the floor conveyor and the centrepoints of two successive navigation interpolation points (Pi) and (Pi + 1). From the deviation (di), correction paths are determined by vehicle-internal transformation of the geometry data set, from which correction paths vehicle-related axis setpoints (Snorm) and ( alpha norm) are formed for driving the steering motor(s) and/or driving motor(s) (10). The steering motor(s) and/or driving motor(s) (10) can be corrected in the space coordinate system by feedback in the space control loop with transformation of the actual axis values (Sact) and ( alpha act) into space coordinates (x,y, gamma ). Each navigation interpolation point (P) is associated with a safety distance (smax) after which an emergency stop of the floor conveyor (1) is triggered as a result of the deviation (di) being too great.

Abstract: Simulated stone products are prepared by spraying a mortar material, in a blast of compressed air, into a mould by means of a gun 10, 14, 16, to which the mortar material is fed via a lateral inlet 12 by a peristaltic pump. Com­pressed air is supplied to an axially extending pipe 18 within the body 10 of the gun, the pipe 18 terminating, within the body 10, just short of a nozzle 16 from which the mortar spray is ejected. The mortar is effectively "atomised" in the spray, so that individual aggregate particles, such as sand grains, coated with cement, are hurled at high speed, in the spray, against the mould surface or against the previously deposited particle to form a densely packed aggregate layer which, in curing, de-moulding and surface etching or abrasion, closely simulates the appearance of natural stone. The apparatus and method disclosed allow,  inter alia , products which are relatively thin and light, and are yet strong, to be produced economically.
