Title: Heat exchanger tube with welded fins - has 0.6 mm thick copper strip pressed onto tube and seam welded
Inventor: ZIEMEK GERHARD DR ING
IPC: F24S10/75
Filed: 1977-10-07
Abstract: Heat exchanger tubes are manufactured from 0.6 mm thick copper strip by feeding it over forming rollers (2) and through the form rings (3). The tube is then completed by seam-welding with the electrode (4) along the abutting edges. The tube then passes under a roller (8) which presses a second copper strip (7) onto the tube. This second strip is then welded by the electrode (9) to form a tube with two symmetrical tangential fins. This method of manufacture produces heat exchanger tubes with much thinner walls and fins than is possible with existing methods.
Patent DE-2746180-A1 (DE)
Title: Composite plastics-insulated pipe - comprises mantle shaped from a strip, particulate insulating material, and coaxial inner pipe
Inventor: OPPERMANN WILLI
IPC: F16L59/04
Filed: 1977-10-14
Abstract: Pipe(s) systems are continuously (plastics-) insulated within a continuously operating pipe-moulding, pipe-welding and pipe-drawing installation. The insulating material is poured cold, in the form of granules or powder onto a cold moving band. Onto the treated band for the mantle pipe, a 2nd inner pipe is placed moving at the same speed. The thickness of the insulating layer equals dia. of mantle pipe minus dia. of inner pipe. The bond is then longitudinally curved to form an almost closed (i.e. narrowly slotted) pipe where additional insulating material is poured in so that a space of about 2mm. is left between insulation and upper inner wall of the pipe after it has been seam-welded. This space is later eliminated when the pipe is reduced in the draw ring of the continuously operating drawing installation, thereby compressing the insulation. This causes the insulation to bear firmly against the inner pipe and prevents formation of voids. Instead of a single inner pipe, several smaller pipes or heating wires or rods may be embedded in the insulating material inside the mantle pipe. The inner pipe is centred inside the mantle pipe by means of centering pins.
Patent DE-2750810-A1 (DE)
Title: Data processor system with high storage capacity and program security - has central processing unit programme store selection protected by gated control signals

Abstract: The data processing system is designed so that with microprocessors and microcomputers with with limited storage capacity, over-written programmes and/or several different programmes can be accommodated. A number of ROM type programme storage modules are provided which are individually selected via the central processor. The selection signals are only operational if certain signals not due to the user, occur in coincidence so that unauthorised reading-out of the data stored in the programme modules is prevented. The selection signals are coupled with different control signals via logic gates. The selection signals from the central processor can be stored in a store change-over unit so that the central processor needs to supply a selection signal only when the user programme is changed.
