Title: Rib profile design - for internally ribbed papermaking drying cylinder heated internally by condensing steam
Inventor: BARP BRUNO DIPL ING
IPC: D21F5/02
Filed: 1975-05-30
Abstract: In a drying cylinder for a papermaking machine, designed for heating by condensing steam and having a cylindrical shell on the inside of which are peripherally running annular ribs, in the spaces between which pipes are fitted for the removal of condensate, the rib profile lies within a region bounded (i) externally by a hexagon symmetrical with respect to the rib axis, itself perpendicular to the cylinder axis, and consisting of a rectangular of full rib width (B) but a height (H1) of 0.75 times the full rib height (H), surmounted by a trapezium of width (B1=0.65B) at the full rib height (H), and (ii) internally by a pentagon also symmetrical with respect to the rib axis and having a width at half the rib height (H11) of (B1=0.7B) and zero width i.e. a point at full rib height (H). By making the rib profile conform as nearly as possible to the parabolic isotherm profiles which occur in a rib in a system in which the heat is produced in the interior of the shell and removed on the outside of this, unnecessary rib matl., which does not contribute to heat transfer but only to thermal stresses due to expansion, is eliminated.

Title: Waste water treatment with coagulants - contg. anionic hydrophilic gp. of carboxylic or sulphonic acid, hydroxide and or phosphate ester
Inventor: KANO MASATAKE
IPC: C02F1/52
Filed: 1975-06-20
Abstract: Waste waters are treated by admixing a coagulant, (I), which contains >=1 anionic hydroxide gp. of a carboxylic acid, sulphonic acid, hydroxide and/or phosphoric acid ester. Colloidal-suspended biological oxygen-requiring and chemical oxygen-requiring matls. are adsorbed on coagulant. Coagulant is pptd. by adding >=1 polyvalent metal salt, an acid and/or organic base, which react with coagulant through formation of water-insoluble matls., e.g. water-insoluble salts or chelate cpds. Process can be used to treat municipal and industrial waste waters, e.g. from food-, soap-, paper-, dye-, leather-, wool washing-, oil emulsifying-, and animal or plant oil factories. Waste waters can be treated which contain organic and inorganic hydrophilic matl. having low mol. wt., e.g. phenols, HCN, free NH3, phosphate and metal ions. Process is highly effective for removing biological oxygen requiring matl. Suspended-, biological oxygen requiring- and chemical oxygen-requiring matl., in any concn., can be removed quickly, on a small space. Colloidal particles become coarser. Filtration and water-extn. are improved. In an example, 51. leather factory waste, contg. 3200 p.p.m. biological oxygen-requiring and 2800 p.p.m. suspended matter, was treated with 220 p.p.m. Na glycol cellulose, 140 p.p.m. Al sulphate and 3.5 p.p.m. polyacrylamide. Filtrate contained 96 p.p.m. biological oxygen-requiring matter and 19 p.p.m. suspended matter.

The valve and counter are combined to form a single unit mounted on a support (1) above a base-plate (8) or a belt for the containers. The support is a crossbar carried on two uprights (4) and lowered over the containers from above. The bases of the uprights can be joined to the baseplate. A separate support (9) for the containers, can use a clamp (10) to raise or lower this support on the side uprights.
Patent DE-2538780-A1 (DE)
Title: Tractor gearbox gear coupling - has internally toothed operating collar with inclined friction discs which increase synchronising force
Inventor: DROESCHEL HELMUT
IPC: F16D23/06
Filed: 1975-09-01
Abstract: A tractor gearbox has a gear wheel coupling with an operating collar (14) which is normally held in a neutral position by radially spring loaded pins (16, 17, 18). The collar (14) has internal gear teeth (15) which, after coupling, are in mesh with either one of the neighbouring gear wheels (1, 2). Before the gears are coupled, a synchronising assembly produces equal rotational speed between the gear wheels. A number of friction discs (27) are located in an annular chamber formed by two tapered friction rings (26, 29). When the collar (14) is operated, the axial force moves the friction discs (27) into a true radial plane, thus producing a lever action which increases the operating force. An externally tapered friction ring (19) is then pushed into a matching groove of the selected gear.
Patent DE-2541847-A1 (DE)
Title: Improvided circular saw - incorporates individual saw tooth inserts to reduce noise and saw dust
Inventor: HIRAIWA MOTONORI
IPC: B23Q11/00
Filed: 1975-09-17
Abstract: The saw blade (1) has individual saw tooth inserts (4), positioned on its circumference. The inserts are fastened via their shanks, in notches (3), distributed over the blade circumference at even distances. The inserts may be rectangular, or neighbouring inserts may have tooth sections, sloping in different directions. This arrangement avoids the customary gullets of the saw teeth by mounting directly on the outer circumference of the saw blade. This removes the cause of "Karman" eddy currents arising when the saw teeth cut the air at high speed in the load-free condition. Noise and spread of dust are also reduced.
Patent DE-2542795-A1 (DE)
Title: Optoelectronic sensor with buried layers - produced by second shallow ion implantation reversing conduction of doped layers near surface
Inventor: KNAUER KARL DIPL ING
IPC: H01L27/148
Filed: 1975-09-25
Abstract: An optoelectronic sensor which operates on the charge-injection-device principle consists of an n-doped substrate a buried p-doped collector layer and an n-doped layer over it. Ion implantation produces first by deep action a p-type buried channel. The layers near the surface are converted to the n-types by a second ion implantation with less energy and an n-type dopant. This saves the combination of epitaxial operations with diffusion processes and uses instead standard MOS prodn. procedure.
Patent DE-2545931-A1 (DE)
Title: Injecting foamed plastic insulation into coaxial cables - to obtain controlled expansion and form uniform cell structure, aided by lubricant addition
Inventor: DITSCHEID HANS LEO DIPL ING
IPC: B29C44/32
Filed: 1975-10-14
Abstract: Insulated wires and conductors, esp. for high-frequency coaxial cables with foamed plastics insulation, are produced by immediately after leaving the extrusion head, the plastic insulation enters an expansion chamber at an internal pressure of about 5 Torr, the walls of this chamber being at the same temp. as the extrusion head. The residence time of the insulation in this chamber is sufficient for 95-98% of the theoretical total expansion to be achieved before it reaches the end of the chamber. Before reaching the end of the chamber the insulation is coated with lubricant, and on leaving the chamber it passes through a calibration stage. The vapour pressure of the lubricant, at the temp. of the expansion chamber and insulation, is below the pressure (e.g., 5 Torr) in the expansion chamber; the lubricant is water-soluble. Pref. the insulation passes through the expansion chamber in a trough filled with the lubricant, so that the buoyancy largely balances the self-weight of the insulation. The pref. lubricant is polyethylene glycol. Pref., a pre-calibration orifice plate is mounted inside the expansion chamber. The method enables a high degree of foaming to be achieved in combination with excellent homogeneity of the cellular structure of the insulation, without the use of complicated or costly equipment.
