Patent DE-1817399-A1 (DE)
Title: Introducing chemicals with liquids especially - used for water purification
Inventor: KAEMPER FRIEDRICH
IPC: C02F1/68
Filed: 1968-12-30
Abstract: chemicals are introduced into liquids in predetermined amounts by passing a stream of the liquid through a granular bed of a substance, which dissolves in the liquid to the desired concentration. In order to avoid excessive dissolution, when the flow of the liquid is stopped, the apparatus is constructed in such a manner that the air enclosed therein expels the liquid from the granular bed when the flow is stopped. The liquid is introduced from the bottom of the apparatus through a pipe which nearly reaches the top of the apparatus; the overflowing liquid flows down through a bed of granular chemicals, and then through a filter. The apparatus is especially suitable for treatment of drinking water with e.g. phosphates (5mg./1.).

Patent DE-2063305-A1 (DE)
Title: Acetylated cardiotonic glucosides
IPC: C07D309/00
Filed: 1970-12-23
Abstract: Acetylated cardiotonic glucosides are produced by reacting the glucoside with an alkyl orthoacetate and submitting the resulting cyclic orthoacetate to partial saponification. The intermediate cyclic orthoacetate may be isolated and/or other free OH gps. acetylated if desired. This process enables acetyl gps. to be introduced into desired positions on the pyrannoside radical of the glocoside. Preferred products are alpha-digoxin, alpha-digitoxin, and 2'-acetyl-proscillaridin. The products are of value in the treatment of cardiac insufficiency. They are more readily absorbed than the parent glucosides.

Title: Lime recovery from (sugar ind) waste slurry - by heat treatment in suspension in rising hot air stream
Inventor: SCHOPPE FRITZ DR ING
IPC: C01F11/02
Filed: 1972-11-23
Abstract: The process comprises introducing the preheated slurry and a calculated amt. of added fuel into a hot combustion air stream (III), which is directed upwards, and mixing intimately with this, the velocity of (III) being high enough to keep the solid particles up to a certain size in suspension for a certain time. The stay time for larger particles is greater than that of small ones, so the large particles fall and are collected and discharge. Temp. of air stream and throughput are regulated so that the particles are heated at over 400 degrees C/s and remain in the combustion and reaction zone for 1 s, whilst the air ratio in the combustion reaction is >1.20 (1.40-1.60). The calcined particles are sepd. from (III) at a temp. below which the lime reacts with the CO2 contained in (III). The CaO prod. is suitable for re-use in sugar mfr.

Title: Glass pipes to replace iron in ammonia soda process - reduced iron content in soda with less corrosion and better heat transfer
Inventor: SCHNEIDER HORST
IPC: C01D7/18
Filed: 1973-04-12
Abstract: In sodium bicarbonate prodn. by the Ammonia-Soda process, the cooling of the sodium bicarbonate suspension at the bottom of the carbonation columns is achieved using glass tubes. The distilled gases, the calcination-gases and the saturated liquid are pref. cooled by the same principle. Filter-clear lye can be used as a cooling medium. The insertion of the tubes in the tank ends is achieved with rubber rings, caulking with soft metal or with an adhesive. The use of glass instead of centrifugal castings or steel improves the heat-transfer and increases the running-time between tube-cleaning operations. The iron content of the soda is reduced by 5 g/t. The mother liquor can be preheated: sodium sulphide is saved; and the cost of replacing tubes is reduced.

Patent DE-2364214-A1 (DE)
Title: Continuous automatic adjuster for braking system - has worm gear adjuster to eliminate free play via friction drive to avoid overload
Inventor: HAGIU FAUST
IPC: F16D65/60
Filed: 1973-12-22
Abstract: Adjustment of a brake element is effected by rotation of a pinion gear driven by a worm gear. The worm gear relies on a friction clutch formed by a conical surface on the adjuster shaft. The worm is pre loaded against the taper by a coil spring. One end of the adjuster shaft has an inner sleeve that is threaded onto the shaft. An outer sleeve locates on a tapered outer surface of the inner sleeve and has an external thread profile that mates with a similar profile in the adjuster housing. A spring eliminates any back lash in the arrangement. Any play in the braking system results in rotational motion of the sleeve that is transmitted to the shaft. The worm gear rotates via the friction drive and the pinion moves to eliminate the play. When correctly adjusted the friction drive slips to prevent further loading.
Patent DE-2400801-A1 (DE)
Title: Flashing light generator circuit for motor vehicles - has a stable saw tooth oscillator and transistor monitor to indicate circuit failure
Inventor: SEITTER WOLF
IPC: B60Q1/38
Filed: 1974-01-09
Abstract: The oscillator has a single transistor with a switching relay in the collector circuit. This controls the winker circuit via a current resistor. There is also a transistor monitoring device for the resistor. If the voltage across the resistor falls due to a fault in the flasher circuit, a timed circuit is switched into the switching relay producing higher frequency flashing. This is achieved by the base layer of the switching transistor having a contact with a condenser via a voltage divider. This is controlled by the monitoring transistor. The connection of the base layer of the condenser is either via a resistor to the base layer of the switching relay or via another resistor to the flasher output. The monitor transistor is designed as a two stage amplifier to increase the frequency.
