Title: Appts for treating flowing media - with tubular part, and slotted partts dividing tubular part into spiral channels
Inventor: CLASEN HEINRICH
IPC: B01J19/24
Filed: 1974-07-19
Abstract: Appts. for treating flowing media has a tubular part and parts (I) that divide the tubular part into spiral channels arranged around the lengthwise axis of the tube, and have long edges extending to the tube wall, and end edges forming an angle with the adjoining part (I). The parts I have slots running in the lengthwise direction of the tubes on their ends, and channels are formed by combining the parts of I in the region of the slits. The slits are spirally shaped to correspond to the spiral shaped configuration of the parts I in the combination. Heat exchange, mixing, drying, emulsifying, dispersing, gasification, gas washing, extraction, melting, absorption, dissolving, and chemical reactions, e.g. polycondensation, polymsn., oxidn., and neutralisation. Provides a quasi-plug flow in the laminar region. This prevents decomposition of heat sensitive media, e.g. spinning solns., and gives better quality prods. The shear action can be varied in accordance with the viscosity of the media, and the degree of homogenisation reqd.

Title: Single or multistage gas-solid contacting - by solids injection into cyclone for pollutant removal from exhaust gases
Inventor: HUENLICH HANS-WERNER DIPL ING
IPC: B01D53/34
Filed: 1974-08-06
Abstract: Exhaust gases contg. toxic or malodorus pollutants which can be gases or aerosols are treated with solid additives to absorb or adsorb the pollutants. The exhaust gas is passed into a cyclone into which a stream of particulate or powdered material is injected by means of a pneumatic conveying system, through an annular formed dip pipe which sprays the solids around the gas outlet; the solids being deflected outwards into the cylindrical part of the cyclone. A medium or heavy phase conveying system is used so that the total gas flow is not significantly effected by the conveying gas flow. Two separate contractors may be used for removal of e.g. SO3 with HCl; and optimum mass transfer is achieved.

Title: Recovery of cellulose from knotter pulp - residue responds to second digestion treatment
Inventor: HOYE JOHN
IPC: D21C3/22
Filed: 1974-08-19
Abstract: The mfr. of cellulose with a high degree of whiteness from knotter pulp. the novelty being that the residue from a digestion treatment is given a second treatment with bisulphite- or sulphite-lye, after which the cellulose materials obtd. are bleached in a known way. It is pref. to remove the fibres and mill the residue and then add it to a normal batch of chips for digestion. The advantage is the recovery of 1-2% or more of material which was formerly waste or solid at a very low price. Knotter pulp responds easily to a second digestion treatment and up to 5% can be added back to the digestion cycle or treated on its own with e.g. ammonium bisulphite lye; the product obtd. is easy to bleach.

The Scheelite crude ore slurry is treated with 0.1-0.2% NaOH (as solids) referred to the solids of the slurry, in such a manner that at beginning of flotation the pH value is adjusted to 10-11.5. After the slurry has been treated with caustic soda, it is further treated for 2-30 min with Na water glass (d. l. 37) in an amt. of 0.05-0.3% referred to the solids of the slurry. As collecting agent is used satd. or unsatd. fatty acids or their alkali salts with 5-20C atoms, and/or alkyl sulphates with 10-20C atmos.

Title: Protection circuit for idling TV camera - is for facsimile transmission systems and has switch in lines that supply HV generator
Inventor: HEISTER HEINZ
IPC: H04N3/20
Filed: 1974-12-18
Abstract: The protection circuit, for idling television cameras in facsimile transmission systems or similar, protects the camera tube against energetic ions during its idling period -- i.e. when the viewing area is blank (no video signals) but the tube is switched on. A switching signal is derived from the video signal or the synchronisation signal and used to control a switch that alters the potential on at least one of the tube electrodes to prevent energetic ions reaching the cathode. This switch (SCH) lies in the supply lines to the high voltage generating circuitry (HSP).

Title: Automatic brake wear adjuster - turns nut on application of brake but prevents turning on release of brake
Inventor: GEHR KASPAR DIPL ING
IPC: F16D65/56
Filed: 1975-06-12
Abstract: An automatic brake wear adjuster has a nut loaded by the brake return spring against the flanks one side of the thread of a screw. On application of the brake, the actuating piston urges the nut against the opposite flanks and thereby causes the nut to return and take up wear. To prevent turning the nut when, on release of the brake, the piston urges the nut against the flanks one side the latter have a self-locking flank angle. The screw is connected to one end wall of th actuating cylinder and slides axially for manual application of the brake.
Patent DE-2526514-A1 (DE)
Title: Water penetration prevention behind building structure seal - using plastic compound treatment of seal carrier, with capillary and pore restriction
Inventor: SCHAEFER HERBERT
IPC: C04B41/48
Filed: 1975-06-13
Abstract: The purpose of the process is to prevent water from penetrating behind, or trickling down, where a sealing material has been applied on an absorbent bearing unit, in buildings and where the effect normally is that the sealing ultimately becomes dislodged. This involves preliminary treatment of the sealing bearing unit with an alkali-resistant plastic compound containing a solvent. The capillaries and pores are restricted, to prevent any further water penetration, producing a water barrier zone on the surface; this is, however, moisture permeable. The foil sheets or lengths of sealing material can then be applied without any further treatment.

Title: Dyeing textile by passage around roll with transfer sheet - and applying vacuum so dye transfers to textile from transfer sheet
Inventor: LOPATA KARL PETER
IPC: B41F16/02
Filed: 1975-09-17

Title: Adjustable pressure step up of reduction valve - has membrane piston operating double valve which governs controlled pressure
Inventor: RAUSCHER WOLFGANG DIPL ING
IPC: F15B3/00
Filed: 1975-11-20
Abstract: The ratio between control pressure and controlled pressure in the step-1p or reduction valve is formed by the surface ratio of the piston faces acted upon by the appropriate pressure. The face of a membrane piston is acted upon by the controlled pressure increased or reduced according to position. This membrane piston operates a double valve which controls the controlled pressure and has a moveably supported valve seat in the valve housing. Specifically, the membrane piston (12) acts with the axially moveable outlet seat (28) at the double valve, whose inlet valve body (24) is rigidly coupled with the outlet seat (28).
