Patent NO-168730-B (NO)
Inventor: EIDMANN JUERGEN FRITZ
IPC: F28D9/00
Filed: 1989-08-04
Abstract: The invention concerns a heat-enchanger comprising at least one cross-flow heat-exchanger module (M) having two alternately attached sets of plates (1a, 1b). Each plate (1a, 1b) has internal channels (5a, 5b) for gas circulation which extend longidutinally, parallel and unidirectionally inside the plate (1a, 1b). The channels (5a, 5b) in one set of plates (1a, 1b) are aligned in the same direction and at a predetermined angle to the direction of alignment of the channels (5a, 5b) in the other set of plates (1a, 1b). According to the invention, a certain number of plates (1a, 1b) of said module have at least one opening (E), obtained in particular by cutting, which facilitates heat exchange between the gas streams. The invention is useful in ventilation or air-conditioning installations in enclosed spaces such as offices, cinemas, theatres, conference rooms, indoor stadia, private homes, apartment blocks, factories, etc.

IPC: D21H23/70
Filed: 1990-11-06
Abstract: The appts. to coat a moving paper or cardboard web has a roller spreader as the first coating stage, fitted with fine peripheral grooves packed closely together to give a low volume layer as a dose as the mantle surface of the first roller (1) guiding the web. The applied mass is compressed in the gap between the first roller (1) and a counter roller (2) so that a thin layer of the coating mass remains, particularly the solid pigment portion. The solid content of the coating mass for the first applied coating is a max. of 70%. The pref. solid content of the coating mass in the first stage is 50-60%, and the coating is applied at a rate of 6-40 ml/m2, especially 12-22 ml/m2. A further roller blade, with peripheral grooves, applies a second coating where the web passes round a second guide roller (3) using a coating mass with a solid content of max. 70% and at least an absolute 10% higher than in the first coating mass as a pref. 60-70%. Designed for coating cardboard web, a doctor blade can be used instead of a roller applicator, or a suitable bar.

Patent ZA-825595-B (ZA)
Title: Particulate compositions useful as plant growing media additives
Inventor: BOSLEY JOHN ANTHONY
IPC: C09K17/22
Filed: 1982-08-03
Abstract: Superabsorbent gel compositions useful as plant growing media additives are prepared from a copolymer of acrylamide and acrylic acid salt in a molar ratio of 70:30 to 95:5, cross-linked such that less than 30% by weight of the dry polymer is water-soluble and the gel can absorb releasably at least 15 times its own weight of water. The gel composition is therefore tailored to the needs of an agricultural/horticultural context because it has long-term stability in natural soil, low solubility that would otherwise lead to poor soil properties, and good water absorbency. Preferred gel compositions in foam form are described.

Title: Process for after-treating extraction residues originating from the decontamination of phosphoric acid
Inventor: SCHIMMEL GUENTHER
IPC: C02F1/66
Filed: 1982-09-09
Abstract: The disclosure relates to a process for after-treating extraction residues, termed raffinates, originating from the extractive decontamination of crude phosphoric acid. To this end, the disclosure provides for the raffinates to be converted to two separate solid matter fractions of differant chemical composition by admixing the raffinates with a calcium compound so as to establish a pH-value of 1.2 up to 2.5. Next, the resulting precipitate consisting essentially of gypsum is filtered off as a first solid matter fraction, and washed with water. The resulting filtrate and the wash water are made into a mixture and predetermined proportions of calcium compound are added so as to obtain, after complete reaction, a fully reacted filter cake with a pH-value of 9 up to 12, the resulting suspension being filtered off at a pH-value of 6 to 8. The filter cake consisting essentially of calcium phosphate is separated as the second solid matter fraction, and allowed to react completely.
