Patent DE-3990711-C1 (DE)
IPC: B22D11/12
Filed: 1989-06-24
Granted: 1993-03-25
Abstract: The invention concerns a process and an installation for manufacturing a metal strip with a fine-grained or uniform structure and having a thickness less than or equal to 10 mm. Immediately after casting, the strip undergoes a second treatment, namely adjustment of the treatment temperature and plastic deformation of the strip, virtually without any reduction in thickness, and possible subsequent annealing and cooling in function of the nature of the strip material. This continuous production of a metal strip which has the desired final dimensions and contains no structure undesirable for subsequent use is obtained by simple means and without expensive rolling.

Title: Thermal spray coating of metallic surfaces - by spraying powdered mixt. of ceramic, metallic or carbide-like material in gas stream via jets onto pre-blasted surfaces
IPC: C23C4/12
Filed: 1992-10-31
Granted: 1993-12-23
Abstract: Metallic surfaces receive a ceramic, metallic, or carbide-like coating using a thermal spray process in which powder particles are heated and accelerated in a stream of gas and then sprayed via a jet onto the surface, which has been subjected to blasting as a pretreatment, the novelty of the process being that: at least a portion of the powder particles emanating from the jet are heated to below their m.pt., and the surface is pretreated by blasting. The powder mixt. introduced via the jet contains 10-90 vol.% spraying additive of fine particle size, and 90-10 vol.% blast additive of distinctly coarser particle size and high m.pt., i.e. higher than the gas temp. in the jet. The spraying and blast additives, of either similar or different type, are introduced separately into the jet, where they are mixed before use. One partic. advantageous modification involves maintaining jet gas temp. below the spraying additive m.pt. during surface pretreatment and then elevating it above spraying additive m.pt. during coating, said temp. changes being achieved by regulating introduction of combustible gases, oxidising agents, coolant gases and/or powder carrier gases. ADVANTAGE - A less time consuming process with decreased appts. requirements compared to prior art processes is achieved by simple means and with low energy requirements.

Abstract: FIELD: materials-handling machines. SUBSTANCE: prior to brinding gripper to load, applied to permanent magnet control coil is current pulse to automatically bring it to magnet built-in load-lifting means, and load is transported. Magnets in load- carrying means are located symmetrically to its vertical axis. Gripper 1 is suspended from flexible suspension to lifting means. Current pulse is passed through control coil 3 to impact magnetic properties to gripper 1. Using load-lifting means, gripper 1 is brought to load 8 to approach load carrying means 6. Processes of approaching, bringing and centering of gripper relative to load are automated and speeded up due to interaction of magnetic fields of gripper and load-carrying means. Further automatic approaching of gripper and load-carrying means results in their joining and griping of load. Then, load is transported and released by sending pulse of reversed polarity. EFFECT: higher efficiency in application (in extreme North regions in unloading containers from ships directly on nonequipped coasts); in this case, gripper is suspended from helicopter which in flight executes slinging of spreader installed on container. 4 cl, 4 dwg
