Patent DE-2817860-A1 (DE)
Title: Rotary disc filter for coal and anthracite slurries - having overflow feed distributor into filter trough with distributor baffles to give uniform cake formation
Inventor: KLOTSMAN VLADIMIR LEONIDOVITSC
IPC: B01D33/00
Filed: 1978-04-24
Abstract: Disc vacuum filter has a trough with weirs for the slurry feed in. The discs are attached to a rotating shaft and dip into the slurry in this trough. Passages inside the shaft and disc connect it to a vacuum source. The slurry is fed into the troughs via inclined weirs. There are also a number of protruding baffles from the wall of the trough to distribute the slurry and prevent sedimentation of the slurry to the base of the trough. Used esp. for filtering polydispersions such as arise during the purification of coal and anthracite. The system ensures that a uniform cake forms on the discs and that a thicker cake does not form near the periphery.

Title: Chimney pipe made by extruding clay and chamotte - contg. basalt grains which create pores during extrusion so pipe has high resistance to thermal shock
Inventor: SCHIEMENZ FRIEDRICH DIPL ING
IPC: C04B38/00
Filed: 1978-07-01
Abstract: The internal structure or texture of the pipe includes numerous pores with longitudinal axes which are pref. parallel with the walls of the pipe; and a grain of stone is pref. located at one end of each pore. The pipe pref. has 10-25% porosity, and a thermal shock resistance of 15-40 cycles when tested to DIN 51068, Sheet 1. The pref. grains are 2-6 mm in size and possess a Freshen hardness >180 N/mm2, these grains being esp. basalt, althrough they may alternatively be granulated slag. The pipes are pref. cut from an extrudate made from a mixt. of chamotte, water and grains, which form tail-shaped pores in the extrudate; the cut pipes are baked. The tail-shaped pores in the pipe texture provide high resistance to thermal shock, thus reducing the tendency of chimney pipes to crack and leak gas and smoke.

Title: Measuring thermal consumption of hot water heating systems - using throughput meter, in each heater regulating valve, with peripheral holes in chamber wheel
Inventor: QUISBROK ROLF
IPC: G01K17/06
Filed: 1980-02-01
Abstract: An arrangement for measurement of thermal consumption in hot water circulation heating systems with a regulating valve at each heat load point in the closed pipe system is immune from external influences. It provides basic data from which exact heating costs can be calculated. A water throughput meter is built into each regulating valve.

IPC: F16B15/06
Filed: 1980-03-01
Abstract: A building panel or sheet for surface heating, i.e. underfloor, wall or ceiling heating systems, comprises insulating material and an anchorage layer through which pipe fixings pass for attaching the heating pipes. This anchorage layer is formed of a continuous plastics sheet (I) possessing high impact strength and toughness. Pref. (I) has a large number of indentations formed in it, more specifically by deep-drawing or embossing, and these indentations are in a regular pattern. (I) is pref. bonded to the panel, which itself is of plastics foam, pref. foamed into the facing sheet.
