Patent DE-4012905-A1 (DE)
Inventor: KOWALEWSKI JOERN DIPL ING
IPC: H04N1/46
Filed: 1990-04-23
Abstract: In the process proposed, colour values are obtained by scanning an original copy. The full-colour values of the three printing colours plus white are measured. Then guider colours are determined which bear a relationship to the printing colours which is as close as possible to linear. This is achieved by positioning the chromaticity region of the printing scale in such a way that each of the primary stimulus values of the guider colours on the chromaticity diagram lies on a straight line from the scale-colour curves through the white point, the triangle lying between the primary stimulus values enclosing the chromaticity region of the printing scale. The scale distribution of the primary stimulus values is matched to the printing colours by a third root. The number of areas to be scanned is determined using the measured values of the space diagonals. The printing table is then generated by cubic spline interpolation.

Title: Treating water used for cleaning food smoking equipment - by reducing pH of water by acid, mixing with bentonite, sedimenting and passing over carbon filter bed
Inventor: HELBACH MAX DR RER NAT
IPC: C02F1/66
Filed: 1990-04-25
Abstract: In treating waste water from smoked food prodn. units, acid is added to the water to bring its pH value to 1 to 2, it is then mixed with silicate flour and undergoes a sedimentation process, from which the remaining liq. is taken to a C filter. Sodium bisulphate is the pref. acid, and the silicate flour is pref. in the form of bentonite. Granular lignite coke is used in the carbon filter, and the water remains in contact with it for 0.5-1.0 hrs.. The filter is regenerated by repeated flushing with clean water. The treated water may be recirculated for further use in cleaning the smoking equipment and chambers, as may be the water used for regenerating the carbon filters. USE/ADVANTAGE - This invention applies to the treatment of water which has been used for cleaning equipment used for producing smoked fish etc., and which is therefore very alkaline and is contaminated with smoke and with food particles. The chemical oxygen deficiency of the waste water is reduced to an acceptable level using an economical procedure.

Patent DE-4020658-A1 (DE)
Inventor: ALBRECHT SEPP
IPC: G01N21/89
Filed: 1990-06-29
Abstract: A scanner (22) is assigned a reflected-light line (32) above a target-disc transport path and a transmitted-light transmission line (28) below this transport path. When a shot hole comes into the detection range of the scanner (22), the disc band is sensed by this in lines and a plurality of hole edge points are determined, these being combined arithmetically to form a polygon from which the shot- hole centre is calculated. Simultaneously with the entry of the hole- edge points, the same scanner (22) detects a number of points of the target-disc ring adjacent to the shot hole. An arc segment of the disc ring is calculated arithmetically from these ring points and its centre point is determined. The shot result is calculated from the distance between the shot-hole centre and the disc centre. <IMAGE>

Title: Thickness meter for blown film tubing - is mounted on ring round tubing and above extruder nozzle, and is rotated independently of speed of rotating or reversing extruder head
Inventor: VOSS KLAUS-PETER DIPL ING
IPC: B29C48/10
Filed: 1990-11-19
Abstract: Equipment measures the thickness of blown thermoplastic film tubing from a rotating or reversing annular nozzle and drawn through lay-flat rollers, using a measuring head to test round the circumference of the film tubing. The head is mounted on a ring round the blown tubing; the overall outer framework of the machine is driven to rotate about an axis which is also that of the tubing; the ring is driven round at a speed which differs by a set amt from the angular speed of the extruding nozzle. - Rotating nozzle has a fixed frame (1) with top traction rollers (2) to lay-flat the tubing (4) from its extruder (3). A ring (6) is welded on above the rotating extruder head (5) and it (6) carries an inner rotating ring (7) with toothed rim (8) engaged by a drive (10). The thickness meter head (11) is attached to this ring (7). The circumferential speed of this head (11) is thus independent of that of extruder head (5). The signals generated from the meter (11) are transmitted to suitable controls.

Title: Synchronising circuit for video recorder luminance and colour signals - uses trigger pulse derived from colour signal to clock luminance signal into charge coupled device serial register
IPC: H04N9/893
Filed: 1991-06-06
Abstract: Luminance and colour signals from separate tracks (S1, S2) of a magnetic tape (1) are read by separate recording heads (K1, K2) and passed to a pulse extractor (4) and a charge coupled device delay unit (8). The pulse extractor extracts a synchronising pulse (c) and passes it via an edge detector to a monostable (10) and an integrator (6). The monostable controls a switch (9) that passes the delay unit output (3) to a differentiator (14) that produces a trigger pulse (f) for a sample and hold unit (7). The latter holds the integrator valve at the level present when the trigger pulse is applied and uses it to drive the voltage controlled oscillator (11) that supplies clock signals to the delay unit, thus forming a feedback loop that synchronises the two tracks. USE/ADVANTAGE - Simple video synchronising circuit capable of being constructed from existing electronic components.

Filed: 1991-06-10
Abstract: A slide valve has a housing (1) with a guide bore (6) and at least one pressure-medium inlet (P) and a plurality of pressure-medium lines (7, 8) extending laterally through the housing into the guide bore. A valve member (3) is axially displaceable in the guide bore and is connected to a piston (4) at one end. At least the valve member (3) is of an elastically deformable material and the valve member has a blind hole (5) which extends in the axial direction from the other end thereof. The pressure medium line (P) extends into the guide bore (6) in such a manner that there is a sealed connection to the blind hole (5) in all positions of the valve member (3). Preferably the piston and valve member are formed as one member. The blind bore may have an oval cross-section with the minor axis aligned with the pressure-medium lines (7, 8) to give increased sealing around these lines. The design is particularly suitable for small valves, but can be used in larger valves in which case the valve member may be provided with reinforcing elements at least in the region of the depth of the blind hole. The pressure-medium inlets may be designed as bushes. The valve may be used as a rotary slide valve or the valve member may be restricted from rotating. The valve member may have a triangular shape. <IMAGE>

Title: Granulation of powdered bleach activators - by spraying with binder soln. in fluidised bed
Inventor: VOIGT DIETRICH DR
IPC: C11D3/39
Filed: 1991-09-02
Abstract: Granulation of powdered N-acetylated bleach activators is effected by fluidising the powder with air and spraying it with an aq. granulating liq. contg. a binder and opt. a surfactant. The powder is injected into the fluidisation chamber at a rate of 200-700 kg/m2.hr., together with up to 120% of this amt. of recycled undersized material ('cyclone dust'), along a path parallel to the median line of the circular chamber but displaced from it by 0.3-0.6 R, where R is the radius. The granulating liq. has a solids content of 15-40% and is injected vertically downwards from a point above the quadrant in which the powder inlet is located, in the form a spray cone whose perimeter is 0.0025-0.1 R from the chamber wall at the level of the fluidised bed. The air flow rate is at least 2000 m3/m2.hr. and is such that the relative humidity of the outlet air does not exceed 95%. The amt. of powder (x) and the amt. of solids supplied by the granulating liq. are such that y = a/x + 0.04, where a = 35-45. USE/ADVANTAGE - The process may be used to granulate bleach activators such as 1,5-diacetyl-2,4-dioxo-hexahydro-1,3,5 -triazine, tetraacetyl-ethylenediamine or tetraacetylglycouril. The process is energy-efficient, allows precise control of the active content of the granules, and gives uniform-sized granules with good storage stability, esp. as components of detergent compsns
