Title: Running track demountable boundary components - comprise interconnected plastic battens with blocks and lugs for drainage gutter recesses
Inventor: HOFFMANN HELMUT
IPC: E01C13/02
Filed: 1976-12-11
Abstract: The system for bordering the running track on a sports field involves a boundary made up from demountable pieces, and is designed to be elastic, easily removed and impervious to rainwater when sited between field and track at the same level, and with no protruding fixed anchor elements. Each piece(1) comprises an elastic plastic batten(2) rounded off at the top, with plastic bearing blocks(5) at set interval underneath. Two of these, at least, have a downward protruding insertion lug(6) for insertion into recesses in a peripheral drainage gutter. An open end of the batten can be horizontally connected to the preceding one on a bearing block, and form-locked downwards. The blocks and lugs may be more elastic than the battens.

Title: Tunnel kiln for sintering ferrite(s) - using conveyors consisting of heat insulating plates fitted with skids gliding along rails
Inventor: BAUMANN HELMUT
IPC: F27B9/00
Filed: 1976-12-16
Abstract: Tunnel kiln for sintering ferrites in a protective gas atmos. has preheating-, high temp.-, and cooling- zones; and conveyor elements which glide through the furnace. Each conveyor element consists of a plate made of a material with high thermal insulation and located in a metal frame fitted with metal skids which glide on metal rails located longitudinally on the kiln base. The heating equipment is located only above the plates inside the tunnel. Each plate may contain a middle layer of material acting as a heat barrier to prevent heat travelling downwards through the plates. The speed of the conveyor elements travelling through the kiln can be substantially increased, increasing productivity, without the need to increase the length of the kiln.

Title: Helical multi-coil heat exchanger for nuclear power installations - has support plates, each plate taking two coils but with neighbouring plates offset to relieve thermal expansion
Inventor: ECKER HANS
IPC: F28D7/02
Filed: 1977-07-28
Abstract: Heat exhanger bundle consists of concentric helical coils. They are mounted by means of support plates which extend the full length of the coil. Each plate takes two coils and an outer plate which takes only one coil is attached to the exchanger shell. The plates are mounted in various radical positions and adjoining plates are offset w.r.t. their neighbours by one tube. Thus if the coils are numbered 1, 2, 3 etc. one row of plates would take coils (1, 2) (3, 4) etc. while the next row round radially would talke (1), (2, 3) (4, 5) etc. The innermost row of single plates would anchor the coils to the inner core. For use in systems where ther is a higher temp. difference between the two fluids in the heat transfer system. Problem of differential thermal expansion is overcome by allowing movement of the coils.

Title: Lead foil mfr. by rolling lead, sheet with tin coating - which increases redn. in thickness obtainable in single pass rolling
IPC: B21B3/00
Filed: 1977-08-17
Abstract: Prior to rolling, the Pb sheet (a) is clad on both sides with a laminated prod. (b), which is itself made by rolling down to the required thickness. Prod. (b) is Pb (b1) coated with a layer (b2) of tin or tin alloy. Layer (b1) is next to Pb (a), so both surfaces of the clad sheet (bab) consist of Sn or Sn alloy (b2). The clad sheet nbab) is rolled into foil in a single pass, using a high tension, i.e. back-pull, on the sheet (bab) on the inlet side of the rolling mill. By coating the initial Pb sheet (a) with a layer of Sn or Sn alloy, a much larger redn. in the thickness of the sheet can be obtd. in single pass rolling. For example, a clad sheet 1 mm. thick can be rolled down to 50-10 mu m in a single pass, which is redn. of over 90%, as compared with only 50% in conventional processes.
