Title: Case-less ammunition for rifles or light machine guns - has nozzle-shaped rear end of propellant charge carrier
Inventor: KALTMANN HANS-JOACHIM
IPC: F42B5/18
Filed: 1973-12-17
Abstract: Case-less ammunition, partic. for infantry rifles or light machine guns, of the known type having a propellant charge carrier (I) connected to a projectile core in the manner of a projectile case extending backwards over the core, but in which the rear end of (I) is nozzle-shaped and the propellant charge in (I) is so dimensioned that it imparts to the projectile an acceleration not only derived from the gas pressure in the barrel but also due to the reaction of the gases flowing from the nozzle. Eliminates the loss of kinetic energy due to excessive friction, e.g. caused by an over-calibre propellant charge-carrier, as well as the danger of tearing this away from the projectile.

Title: Hydrophobised pyrogenic silicic acid - prepd by spraying with a silazane-water mixt.
Inventor: DORN LUDWIG DR
IPC: C09C3/12
Filed: 1974-01-26
Abstract: Hydrophobised pyrogenic silicic acid with a C content of 10 (pref. 7-10) wt. % is produced by (a) spraying pyrogenic silicic acid, while subjecting it to whirling motion, with a mixt. of a liq. silazane which reacts only slowly with H2O, and an amt. of H2O ca. 50% greater than the amt. of silazane, at 0-100 degrees C. (pref. room temp.), and (b) heating the prod. to 130-170 degrees C. to remove volatiles. The prod. is useful as an additive for increasing the strength of polysiloxane elastomers. The presence of H2O increases the liq. volume and thus facilitates the rapid and uniform distribution of the silazane over the silicic acid surface, giving very high surface coverages (cf. a max. C content of ca. 4.5 wt. % when pure silazane is used; DT 2043629). The silazane is pref. hexamethyldisilazane (HMDS). The silicic acid pref. has a BET specific surface of 100-500 m.2/g.

Title: Vehicle epicyclic-hydrodynamic transmission - with ratchet brake to engage reverse gear and operate parking brake in further setting
Inventor: DOERPMUND HEINZ DIPL ING DR
IPC: F16H63/48
Filed: 1974-02-09
Abstract: The transmission comprises a hydraulic torque converter which is coupled directly to an epicyclic gear train. The gear train is operated by a set of brakes, with the first gear operated against spring pressure. This ensures that if the engine and hydraulic system fail, the gear ratio is automatically set into first gear to slow the car. The reverse gear is operated by a mechanical ratchet brake which also serves as the parking brake if it is moved past the reverse setting, to the end of its travel. A simple control system with fail-safe operation is thus obtained.

Title: Scrap pneumatic tyre carbonisation - with volatile products cracked in chamber oven before adding to coal stream products
Inventor: KARWAT ERNST DR ING
IPC: C10B57/04
Filed: 1975-02-15
Abstract: The coke is produced separately for coal and for scrap pneumatic tyres, either in horizontal chamber ovens or in rotary or vertical retorts. The volatile products of the carbonisation are processed jointly. Before the volatile prods. of the tyre carbonisation are added to those produced from the coal, they are passed through a chamber with a program control of the temp. and residence time. This causes them to become cracked and to be matched to the volatile prods. of the coal stream. The volatile prods. from both streams can now be mixed in any desired quantitative ratios without detrimentally affecting the tar processing or the benzole prodn.

Title: Mixed cellulose fibres from timber and annual plants - by mixing long and short fibre material processed together
Inventor: REITTER FRANZ J
IPC: D21B1/00
Filed: 1975-06-14
Abstract: A mixed semi- or full cellulosic material is produced from wood and annual plants, for paper, carton, cellulose and viscose mfr. by reducing the annular plant matter into small particles before boiling, by chopping, cutting or crushing. The wood is reduced to chips as uniform as possible, with a thickness of 0.1 to 3 mm. These are mixed with the disintegrated annual plant matter. The two components are then boiled with the usual chemical additives to form cellulose. The process makes it unnecessary to handle the different types of fibre separately in distinct vessels. Small quantities of long fibred material can be mixed in with the short fibres from annual plants.
