Title: Circular knitting machine - has cylinder cam assembly for needles and dial cam for the sinker platings whereby cams are attached to base by a quick release mechanism
Inventor: SCHNURRER HANS
IPC: D04B15/32
Filed: 1990-04-14
Abstract: A circular knitting machine is provided with a cylinder cam assembly for the needles, and a dial cam for the sinker platines. The knitting cam segments are assembled on a support, which is anchored to the base by a quick release mechanism. - Pref., the cylinder with tricks holding the series of needles in a vertical position. The stem and butt align with the knitting cam. This is held to the segment by means of projecting studs through the face which in turn has an assembly arrangement. In the base, the projecting claw is at an angle, and this meets the linking claw at the corresp. upward angle of the linking claw in the segment. The linking claw is set in a screw tension mechanism. The shape of the claws is with a hook shaped face, which interlock when brough together from opposing directions. The screw and tension mechanism of the linking claw draws this upwards to clamp. The setting of the bolts attached to the claws does not permit them to turn.

Inventor: POLACZEK JERZY DR
IPC: C10B55/00
Filed: 1990-06-16
Abstract: In the prepn. of bituminous coal tar carbon intermediates can be recovered. The prepn. comprises separating the  tars contg. max. 1.5 wt.% quinoline visols. (QI), storing separately and distilling, in which for each H20-contg. light oil fraction, a middle oil fraction boiling at a max. 300 deg.C and a soft pitch are obtd., one with a low and one with a high QI content. The soft pitch is then vacuum distilled producing an anthracene oil boiling at approx. 450 deg.C as well as normal pitch. The anthracene oil opt. with further high boiling aromatic hydrocarbons was added to the solids-deficient crude pitch before distillation. USE/ADVANTAGE - The soft pitch is used for the delayed carbonisation under reduced pressure and the normal pitch for the delayed carbonisation under atmospheric pressure (both claimed).  High value carbon intermediates can be obtd. by reducing the  amts. of disposable residues.

Title: Rain water tank for sepg. light and heavy impurities - restricts outflow flow to raise water level above normal and trap floating impurities, and collects sediment
Inventor: WEBER WERNER DR ING
IPC: B01D21/00
Filed: 1990-08-10
Abstract: Walls of the tank (1) extend above the level of the outlet overflow weir (11) to form a clarification zone (18) above the normal water level (8). A flow restricting device (12,20) in the water outlet (10) reduces outlet flow area below flow area of thte inlet (7). This raises water level above the normal water level during periods when water is entering the tank. The max. water level (14) in the tank is determined by a second weir (25) which may be in or upstream of the tank. A baffle (16) having upper and lower edges (16a,16b) in the clarification zone of the tank prevents rotational flow produced by the non-radial orientation of the inlet pipe. USE/ADVANTAGE - Circular or central-symmetric ground plan with an inlet pipe and an outlet weir above the level of the inlet and determines the normal water level in the tank. Good sepn. and retention properties for (non)-buoyant contaminants in the water.

Patent DE-4136979-A1 (DE)
Inventor: MUELLER MARTIN DIPL ING
IPC: F15B11/028
Filed: 1991-11-11
Abstract: The pressure-relief valve (10) proposed has an obturator (18) which operates in conjuction with a valve seat (17). The obturator element (18) is biased to press against the seat with a certain pressure, the biasing force being exerted by a membrane (21) either directly or through additional spring means. When a given maximum pressure is exceeded, the membrane (21) comes to rest against a stop surface (26). Open mounting of the obturator element (18) enables narrow gaps which are susceptible to fouling to be avoided. The pressure-relief valve is compact, but ensures that the obturator element sits securely in the valve seat.
Patent DE-4138496-A1 (DE)
Inventor: OSTRUP HEINRICH
IPC: A01D41/14
Filed: 1991-11-23
Abstract: The present invention relates to a self-propelled combine harvester with a two-part cutting unit, the troughs of the cutting-unit halves having pivotable sensors (24) which sense the ground contour. So that these sensors (24) are not damaged during road transport, there is provided a linkage (13) which is actuated automatically as a result of the folding together of the two cutting-unit halves, in such a way that the sensors (24) bear against the bottom of the troughs. This prevents the sensors (24) from coming into contact with the road and being damaged or the view of the driver of the combine harvester from being sharply restricted because the cutting-unit halves are raised too high. <IMAGE>
