Patent DE-3912611-A1 (DE)
Inventor: KORBACSICS JANOS
IPC: C08F2/18
Filed: 1989-04-17
Abstract: Highly acidic cation-exchange synthetic resins, such as sulphonated styrene-divinyl benzene copolymers, are usually contaminated by acid formed during sulphonation. The production of waste acid as a by-product of maximum sulphuric acid concentration is achieved when the resin discharged from the sulphonating unit and contaminated with acid is washed with water in at least two washing units of which one is a multi-stage washer while the other is a countercurrent washing column, by taking care to keep the quantity of washing liquor at a minimal level and avoiding the osmotic and heat load on the resin caused by dilution of the acid. The concentration of the sulphuric acid is controlled such that the resin is buoyant in the multistage washing unit but causes the resin to settle out in the counter current column. Part of the heat formed by the dilution of the concentrated sulphuric acid with water is removed during the dilution of the resin-free solutions. <IMAGE>

Title: Pallet loader and unloader for moulding boxes - has gripper head on slide within slide to reduce space and give clearance above loaded pallet
Inventor: BRUDER HARALD R
IPC: B66F9/02
Filed: 1989-07-04
Abstract: The pallet loading and unloading device forms part of a larger system.  Seen in plan, it moves a stack of prepared moulding boxes from a pallet at location (41) to a pallet at location (42) by lifting the boxes with the gripper head (39), moving them horizontally in the direction C and finally lowering them onto the new pallet. Traverse in the direction C is by movement of the slide assembly (19) running in the vertically guided housing (8), and simultaneous parallel movement of a carriage carrying the gripper head and running on guideways within the slide assembly.  The effect of this telescopic movement along the C axis is to leave the loaded pallet clear for further handling in the overall system. ADVANTAGE - Compact design permitting free access to loaded pallet.

Title: Object imaging display for ultrasonic sonic scanning computer tomograph - superimposes echoes of primary radiation into summation image
Inventor: RICHTER KARI DR
IPC: G01S7/52
Filed: 1990-11-22
Abstract: The echoes are formed by a multi-directional primary radiation, such as ultrasound, aimed at the object.

Title: Preventing edge sticking of PET film with coating contg. gelatin - by irreversible deformation of gelatin mol. with hot air, used esp. for photographic film base
Inventor: SCHOENE HANS-JUERGEN
IPC: B05D3/04
Filed: 1991-04-08
Abstract: To prevent the edges of PET films with coatings contg. gelatin sticking together, the novelty is that, after the coating has been dried, the edges are treated with hot air until the gelatin mols. in the coating undergo irreversible deformation. Pref. a blast of 1-2 cu.m/h air at 220-230 deg.C is directed onto both edges of the film, which is moving at 5-15 m/min, on one or both sides, according to whether the film is coated on one or both sides. USE/ADVANTAGE - This treatment prevents loss of film base for PET photographic prods. It inhibits moisture absorption by the gelatin and suppresses adhesion. Simple equipment is used and the continuity of mfr. is maintained. In an example, the edges of coated and dried film travelling at 5m/min were treated with a blast of 1 cu.m/h air at 220 deg.C and 5.0 kPa through 1 mm wide nozzles, 20 mm apart. No sticking occurred during subsequent processing. Using air at 150 deg.C was not effective.
