Title: Grid for casting of paving stone blocks - has wear resistant edges applied by electric welding gun
IPC: B23K9/04
Filed: 1977-12-09
Abstract: The mfg. process for grid elements is particularly for those subjected to a large edge wear and comprises applying a plating on one face of a plate, the plating taking the desired shape of the mesh and constituted of a first wear resistance material, such as a high alloy steel, and then on the other face the plate is cut by means of a burner so that the mesh remains behind with the plating only on one side. The grid can be used in the casting of reinforced concrete blocks and has a harder wear resistance than conventional grid moulds. The machine to carry out the process can be fixed to a tool-holder of a cutting machine and can move an electric welding gun(1) having an electric motor(2) which can apply on a plate(3) a plating comprising weld ribbons(4) of variable width(b). The necessary design can be laid out via the gun. The welding rod comprises a wear resistant alloy which is applied in a protective gas atmosphere. The plate(3) can be of a normal steel. After laying down the ribbons(4) the plate(3) is cut by means of a burner so that the grid compartments(16) remain i.e. those formed between the individual moulds(17) provided to fabricate the composite blocks.

Title: Water pump operated by solar energy - having boiler operated by solar panel driving pump submerged in ground water source to pump water to storage tank
Inventor: BRUESTLE ROLAND ING GRAD
IPC: F03G6/06
Filed: 1977-12-19
Abstract: Solar energy is collected in collector (1) in which the sun's rays are focussed onto the collector pipe. This heats oil which circulates through a coil in boiler (2). Steam is generated and this flows down line (4) via valves (41) and (42). The steam pressure pulses down piston (31), displacing water past non-return valve (51). The water flows up line (5) to tank (7). When the piston has completed its stroke, valve (42) closes and valve (61) opens. This vents the steam to tank (7) where it condenses on plates (72) cooled by the water. When the pressure in (2) is sufficient, steam again flows when valve (42) is reopened. The pump unit (3) is submerged in a ground water source.

Patent DE-2854976-A1 (DE)
Title: Correction process for ROM content - using modified addresses to locate corrected information stored in unused locations
Inventor: KLETT ROLF DIPL ING
IPC: G06F9/26
Filed: 1978-12-20
Abstract: A sequence of instructions held in a r.o.m. is subjected to an address modification process to allow correction of errors in the stored information. Since the information is stored by firing diodes at each point in the memory matrix, a correction of an error may only be made by modifying the address to access a location containing a corrected value. If an error is contained in a specific line, the corrected line is burned into the memory of an earlier location. The address of the previous line is modified to correspond to the location of the corrected value. In operation, the instructions are accessed until the modified address is reached at which point a jump occurs to obtain the corrected value.

Title: Radioactive waste melting and proportioning - in furnace and vacuum transfer to portioning container
Inventor: GATTYS FRANZ JOSEF
IPC: G21F9/30
Filed: 1979-04-14
Abstract: Precisely proportional amounts of fused radioactive waste are transferred from a furnace to a portioning container to which a vacuum is applied. The precise amount of the transferred melt is governed by a large dia. tube and a narrow tube, joining the furnace to the container. Their depth of immersion and entry in the container are so dimensioned that the narrow tube becomes exposed and breaks the vacuum when the portion has been transferred. Products of corrosion are collected in a tray at the furnace base. A precise amount of melt is thus processed to glass beads and identical conditions for the heat dissipation prevents the destruction of the glass structure.
