Title: Paper-making double fourdrinier section
Inventor: SOLLINGER HANS-PETER
IPC: D21F1/48
Filed: 1992-04-15
Abstract: The twin fourdrinier section of a paper-making or cardboard mfg. machine has a fourdrinier support surface within the closed loop of at least one fourdrinier, only at the start of the section where the rigid bars face the bars with a pliable support.     The support surface is only within the fourdrinier loop acting with the bars with pliable supports, or only within the fourdrinier loop with the rigid bars. The facing bars form at least part of the fourdrinier support surface to give a sandwich zone, where the length of the support surface is 10-60% of the sandwich zone. The support surface is partially within and partially outside the sandwich zone, or is wholly within the sandwich zone. The location of the support surface can be adjusted, parallel to the direction of fourdrinier travel. The fourdrinier support surface is a plate or box-shaped component on pliable supports such as springs, pneumatic cushions and the like, to bear against its fourdrinier with a selected pressure force. The leading edge of the support surface is supported by a linkage. The fourdriniers travel horizontally through the double fourdrinier zone, where one is the upper fourdrinier and the other is the lower level.

Patent DE-4226680-A1 (DE)
Inventor: ULLRICH MANFRED
IPC: B24C3/06
Filed: 1992-08-12
Abstract: The proposal is for a mobile centrifugal blasting machine which can be moved in a working direction over areas (4) to be sprayed. It has two spinners (7, 8) arranged side-by-side transversely to the working direction which, during operation, generate a jet of particles (43, 44) directed towards an area (4) to be sprayed. This produces in the impact region (33) of the area (4) a central jet region (49) sprayed by the peripheral jet regions (47, 47') of both particle jets (43, 44) directed towards each other, thus giving a very uniform spray pattern over the area (4).

Title: Polyamide-imide block copolymers - is obtd. by stepwise reaction of di-acid(s), di-amine(s) and tetra:carboxylic acid di-anhydride(s) in sulphone solvent, esp. di-phenyl-sulphone
Inventor: PFAENDNER RUDOLF DR
IPC: C08G73/14
Filed: 1993-09-22
Abstract: A stepwise process is claimed for the prodn. of polyamide-imide block copolymers or copolymers (PAI) with reduced viscosity (RV; 1% soln. in NMP) 0.1-2.0 dl/g which are soluble in polar aprotic solvents. PAI are prepd. from (cyclo)aliphatic or aromatic diacids, diamines and tetracarboxylic acid dianhydrides by (i) producing a polyamide, (ii) condensing this with a polyamide-acid to form a polyamide-polyamide acid block copolymer and (iii) cyclising to PAI, or by (ia) producing a polyamide-acid, (iia) condensing this with diacid and diamine to give a polyamide-polyamide-acid copolymer and (iiia) cyclising to PAI. The separate stages are carried out in diphenylsulphone (opt. substd. with Ph or 1-12C alkyl) or in a solvent of formula (I); A, A1 = H, Ph or 1-12C alkyl; A2 = direct bond, O, S, SO, SO2, CO, NH, N(1-12C alkyl), NPh, =P(O)-(1-12C alkyl) or =P(O)Ph. USE/ADVANTAGE - Use of the above solvents enables the prodn. of high-mol. wt. PAI from the relatively less reactive free diacids, esp. aromatic diacids, with shorter reaction times compared with diacid halide starting materials. The PAI obtd. can be stored in soln. and processed as films or used for coating Cu, brass, Al, steel, glass fibre materials, polyesters, polyamides etc. The PAI have good solubility and very high thermal stability and are free from halide impurities etc.; they are therefore esp. useful for electronics applications.
