Patent DE-4324144-A1 (DE)
Inventor: MEYER PHILLIPPUS JACOBUS
IPC: B07B1/10
Filed: 1993-07-19
Abstract: A highly efficient dry sorter (1) for continuous operation has a conveyor belt cover (4) with longitudinal grooves, with the corresponding conveyor surface arranged obliquely in such a way that the coarser coal runs off over the grooves while the finest coal or substance remains in them. It is thus possible for the finest coal to be extracted from the top while the coarser granules are removed by the lower longitudinal side. The belt conveyor (2) is given the necessary permanent tilt by the fact that to the underside (16) of the conveyor belt cover (4) are allocated edge supporting strips (17, 19) designed to correspond to supporting rollers (22, 23) arranged at a distance along the bearing frame (3). These supporting rollers (22, 23) are supplemented by pressure rollers permitting the even securing of the edge region on both the upper and the lower longitudinal side (20). Dry fine coal is sorted with a high throughput rate and can be further processed without any drying, thus giving rise to the minimum outsize quantities, as tests have shown.

Title: Domestic water filter assembly piston linear motion moved by a pressure redn. and converted to rotary motion by gear
IPC: B01D29/15
Filed: 1993-12-17
Abstract: A reverse-flush filter for a domestic water supply has a housing around a tube filter insert. The housing has a water inlet and an outlet plus a reverse flush inlet which can rotate relative to the filter insert face, and an outlet to remove back-flushed water. Back-flushed water passes via an outlet passage to an outlet chamber. When pressure falls in the outlet chamber a drive unit drives the relative movement between the suction outlet and the inlet side of the filter insert surface, and a valve controls the fall in pressure in the outlet chamber. The novelty is that the drive unit incorporates a linear-motion piston (140) in the outlet chamber (100) which is moved by a redn. in pressure in a low-pressure chamber (204). Further that a gear assembly 148,150) is coupled to the suction unit (86) to covert linear piston (14) motion into the rotary motion required for the suction unit (86).

Title: Internal combustion engine with at least two inlet or exhaust valves and a valve timing gear assigned to these
Inventor: VOIGT DIETER DIPL ING
IPC: F01L1/26
Filed: 1994-02-24
Abstract: An internal combustion engine with two valves (6, 7) of the same type contains a first swivelling transmission lever (9) for their actuation by means of a single cam (5), which lever permanently actuates a first valve (7) and a transmission lever (10) assigned to the second valve (6), between which a claw coupling containing at least a first pair of claws (11, 12) is arranged. The second transmission lever (10) is axially displaceable between a first position, in which the claws (11, 12) of the first pair of claws are in power-transmitting engagement, that is to say the second valve (6) is also actuated, and a second position, in which the claws (11, 12) of the first pair of claws are disengaged. So that the second valve (6) also performs a slight opening movement when in the deactivated condition, at least one second pair of claws (12, 16) is correspondingly arranged over the circumference, the said pair of claws extending axially to such an extent that, even with the first pair of claws (11, 12) disengaged, a drive connection exists between the two transmission levers (9, 10) in a small crank angle range (Fig. 1). <IMAGE>

Title: Method of manufacturing a mask for producing a pattern on a semiconductor component
Inventor: BAE SANG MAN
IPC: G03F7/20
Filed: 1994-06-10
Abstract: A method is described of manufacturing a mask for producing a pattern on a semiconductor component. Material of high reflectivity is provided between a crystal substrate and a patterned chromium layer. The thickness of the crystal substrate is determined with regard to the effect of the stationary waves such that the energy of the light reflected from the patterned chromium layer and of the light reflected again from the crystal substrate base boundary layer is utilised so as to increase the fraction of direct, non-reflected light during the production of an image on a wafer. The light energy which passes through gaps between adjacent regions of the chromium layer on the mask is increased accordingly during the formation of a micropattern on the wafer. This results in a reduction in the exposure time and an increase in the depth of the focal point. <IMAGE>

Title: Optimisation of aerodynamic effect of aircraft wing
Inventor: GLEINE WOLFGANG DR ING
IPC: B64C13/16
Filed: 1994-06-27
Abstract: Flight data are detected during flight and definite curvature changes detected depending on such data as altitude, flight speed and flying wt. The flow for a flight condition and caused by curvature changes is determined by interrogating flow parameters detected by sensors (9-12). The detected parameters are compared with stored optimal demand values for the flight condition, e.g. pressure distribution and separation positions. Difference values are formed and used to derive control signals. The curvature is altered by motors (8) according to the control signals to minimise the difference values. This is repeated until the difference values are nulled.
