Title: Reinforcement for asphalt coatings - by treating with liquid mix of cement, sand and resin
Inventor: OHSMANN HANS
IPC: E01C7/35
Filed: 1974-04-20
Abstract: The solidity props. and petrol and oil resistance of asphalt coatings are increased by treatment with a mixt. of cement, sand and synthetic resin emulsion to which a liquefying agent has been added to give flowability similar to a liquid, so that the whole asphalt coating is covered with this mixt. The hardened mixt. provides an inner reinforcement and protects the coating against petrol and oil. Pref. the synthetic resin emulsion can be PVA acrylates, propionates, butadiene, styrene or mixts. of these. Due to its fluidity, the mixt. of cement, sand and resin flows into the cavities in the asphalt to provide the inner reinforcement. Machines, vibrators and rollers are not necessary for its application. The work output is increased.
Patent DE-2421740-A1 (DE)
Title: Magnetic cylinder lock - tumblers in inner cylinder not protruding beyond external cylinder surface even in locked position
Inventor: HEIMANN GEORG DR
IPC: E05B47/00
Filed: 1974-05-06
Abstract: The tumblers are not spring-loaded, but fitted with magnets, making more space available in the inner cylinder to accommodate the tumblers. Their locking movement is not a centrifugal one, but each tumbler performs a rotary movement around it's own axis. The outer cylinder is provided with a set of circular grooves, in which the flat heads of the tumblers can slide. At one place the grooves have a gap, where the flat heads can achieve the rotating movement. If the correspondingly magnetised key is slid into the key hole the magnetic force arranges the magnets of the tumblers in such a way that their flat heads all coincide with the grooves and the key with the inner cylinder can be turned for opening. If the key is withdrawn, the magnetic forces act on each other in such a way that the tumbler turn with their flat heads into the locked position.

Title: Decarburising ferrochrome or ferromanganese - by oxygen blowing with the melt superheated
Inventor: BREUER FRITZ DIPL ING DR
IPC: C22C35/00
Filed: 1975-09-10
Abstract: High carbon ferromanganese or ferrochrome is decarburised by refining using gas envelope nozzles, e.g. with double walls, the molten alloy being super heated before blowing in oxygen to a temp. >100 degrees C above that of the fusion zone. The temp. is further heated by the blowing to 1650-1900 degrees C for ferromanganese and 1750-2000 degrees C for ferrochrome so as to produce a phase of manganese oxide or chromic oxide having a high m.pt.; this oxide phase is subsequently reduced by introducing lime and addn. of solid producing agents such as Si, Al or their alloys. The operation can be effected with improved yield at above the temp. of the molten alloy using much larger charges than in prior art.

Title: Stockless anchor with hollow crown and flukes - has compartmentation to control disposition of ballast produced by watertight compartments between concrete walls
Inventor: POPPE HORST
IPC: B63B21/44
Filed: 1975-11-28
Abstract: The stockless anchor has a hollow crown and flukes with the crown and flukes made into 2 separate watertight compartments (K), filled about halfway with pourable material. The pourable material is quick-setting (e.g. concrete) and additional partitions (15) are fitted to the watertight compartments. These restrict the ballasting material (F) to one part of the compartments, leaving the remainder (H) empty or to be filled with a lightweight filler. As a result by varying the position of the partitions, the centre of gravity of the anchor can be positioned below the shank pivot (A) or above it, as may be most appropriate to the purpose of the anchor.

Title: Underfloor heating system for bus - has cylindrical impeller fan set across main air duct to retain vehicle ground clearance
Inventor: SONDERHOLZER ALFONS
IPC: B60H1/00
Filed: 1976-05-05
Abstract: The bus is heated by an underfloor system driven by a cylindrical impeller fan (3) set across the main air duct. This draws air over the heat exchanger (14) and passes it to a distribution manifold and from there to the heating duct leading through the floor. The cylindrical impeller provides an even airflow over the heat exchanger and operates silently as compared to a propeller. It occupies a compact space so that ground clearance is not affected. The air is automatically deflected upwards by the rotation of the impeller thus reducing airflow resistance.
