Patent DE-2505905-A1 (DE)
Title: Reinforced, laminated, transmission, especially cone, belt - whose parallel coplanar filamentous reinforcement do not touch one another
Inventor: MEISSNER HORST
IPC: B29D29/10
Filed: 1975-02-13
Abstract: Mfr. of power transmission belts, esp. "V"-belts, of rubber or rubbery plastics, with several superposed layers of parallel filamentous reinforcements extending side of side in co-planar relationship, without touching one another, is claimed. Two or more laminae of reinforcing layers, prepd. with vulcanisable rubber or plastics, are laminated together, between rollers, so as to form a coherent web or band, and are then applied onto a (opt. partly) built-up belt blank. The claimed process replaces the prior-art method of multiple winding of the reinforcing layers in a separate preparatory operation, using a calendar or roller mill. The laminating together of as many reinforcing layers (as allowed for in the present invention) allows belts of any thickness to be built up. The prod. is characterised by uniform consistency throughout its structure.

Title: Rust inhibiting coatings for steel - comprising cement and water with added plastic dried in air before setting, then set and hardened under water
Inventor: KRENKLER KARL PROF DR
IPC: C04B40/02
Filed: 1975-03-13
Abstract: Rust inhibiting coatings for steel surfaces which in service come into contact with moisture or are immersed in water, esp. drinking water pipes, are prepd. by use of a paste, applicable by spraying, centrifuging etc. the coating consisting of cement, water and opt. sand, by a process in which immediately after applicn. of the coating the process of hydration and hardening is interrupted by air drying, esp. with warm air and only continued when the duct is full of water and completed progressively in its normal term. A plastic matl. is mixed in with the cement to prevent the cement particles from being washed away by the flowing water after introducing the steel pipe into the pipeline. When used for a drinking water supply pipe a burst pipe must be fixed quickly, so that a pipe coated according to the invention can be installed and the water set flowing again quickly without washing away the unset cement.

Title: Containment for molten reactive cladding process prods - by enclosing the cladding area with an annulus of sand
Inventor: ADAMS RICHARD CONRAD
IPC: C23C26/02
Filed: 1975-10-01
Abstract: An exothermic reduction-deposited metal cload coating is produced on a planar surface of a metal substrate by supporting the substrate on a bed of insulating refractory material, forming a metal deposition zones by enclosing the substrate with a solid refractory wall, surrounding the zones with a second insulating material to provide a sealing medium to contain any fluid cladding reaction products escaping from the solid wall, and igniting a particulate exothermic cladding material on the substrate surface to be clad. Used for cladding using the aluminothermic reduction process for steel substrates. The migration of any molten reaction product is immediately halted. The containment apparatus for the cladding process is easily installed, removed and does not require an exact fit. It is also reusable, Carbon picking by low C steels is prevented during the cladding process.

Title: Marine log and echo sounder adapter - has impeller providing distance measurement and adjusts sounder registration period for display
Inventor: HOFER ANTON
IPC: G01C13/00
Filed: 1976-01-15
Abstract: The marine log and echo-sounder adapter consists of an impeller wheel attached to a vessel, the revolutions of the wheel being proportional to the distance covered by the vessel. Indication can be via a flexible drive or by means of electronic pulse counting systems. The impeller may be of metal, plastic or wood. The log may be coupled to an echo-sounder by means of a flexible drive and reduction gearing or through electronic control of drive motors e.g. thyristor switching of electric motor armature and stator currents, to control the registration speed of the echo-sounder. By a suitable reduction ratio between the log and the shift mechanism of the echo sounder, a registration rate is obtained which is proportional to ship's speed thus providing a representation of the seabed profile.
