Title: Ballastless permanent way for railway vehicles - has prefabricated concrete supports which rest after alignment on hardenable filling
Inventor: LEIENDECKER JOSEF
IPC: E01B3/40
Filed: 1973-11-02
Abstract: The ballastless railway track support structure is built up from prefabricated concrete components, all aligned by a simple process before final fixing. The building process can be automatic. The foundation consists of lightweight concrete with added foamed polystyrene. The prefabricated slab is placed on this substrate and aligned. The gap formed is filled by injection with a hardenable compound and the aligned slab is hence stable. Slabs are connected with dowels to form a continuous support. The rail is held on a saddle and this saddle forms a mould for plastics container mortar layer used for aligning rail. The rail rests on damping pads and it is clamped by bolts to the slab.

Title: High velocity reaction process - using various means to create purely kinetic or thermal energy
Inventor: SCHWEIGER LUDWIG
IPC: H05H1/24
Filed: 1974-04-16
Abstract: Chemical, technical and physical process for raising the velocity of reactions is applicable to all types of reaction-solids, liqs. and gases, and allows controlled reactions in the required direction. It permits a relatively small initiator by using special surfaces to be used for explosive charges and this can be used in simple weapons. The energy thus generated can be used as propellant (kinetic energy) or as purely thermal energy, or as a desired balance of the two. The process can be used to alter the properties of solids and gases, e.g. decay time. It can be used to obt. previously unobtainable temps. and to create high temp. plasma. It can be used for nuclear fusion. By detonation, a desired spatial direction can be achieved. These processes can be achieved by ultrasonic, high frequency, induction, magnetic fields and lasers instead of current effects. Purely kinetic energy can be balanced.

Title: Abrasion-resistant moulded coke prodn. from brown coal briquettes - with addn. of steam to the gas for drying and preheating
Inventor: LORENZ KURT DR
IPC: C10B53/08
Filed: 1975-08-21
Abstract: Brown coal briquettes are pre-heated, dried and coked in >=3 stages, by circulation, in each stage of hot gas consisting mainly of burnt lean gas from the coking process as in the parent specification. Steam is new added to the hot gas in the preheated and/or drying stages. The preheating and drying rates can be controlled by the addn of steam, and a more gentle transition achieved between expansion of the briquettes during preheating and shrinkage during drying. This reduces crack formation at the surface.
