Patent DE-2430490-A1 (DE)
Title: Pusher-type billet heating furnace - billets are transported on ceramic inserts in sliding shoes pushed through the furnace
Inventor: POHL HANS CHRISTOPH DR ING
IPC: F27D3/02
Filed: 1974-06-25
Abstract: Transport device for continuous and discontinuous furnaces with upper and lower heating for raising the charge to the working temp., using a supporting structure of internally cooled tubes of suitable cross-section. The novelty is that on the tubes, or on guide-rails welded to the tubes, is a row of sliding shoes which can be pushed through the furnace and form a continuous row of carriers for ceramic inserts on which the charge rests and which provide thermal insulation. The ceramic inserts pref. have different thermal conductivities and strength and are easily interchangeable; they are pref. shaped like a roof and are used in a pusher-type billet heating furnace. Used for heating e.g. steel slabs to the hot-rolling temp. The bottom surface of the billet is exposed to the heat and the shoes travel with the billet so there are no scratches on the billet surface due to friction; heat transfer from the billet to the supporting tubes is reduced and the sliding surfaces can be lubricated.

Title: Sealing ring in P.T.F.E. for butterfly valve - with internal ring spring, suitable for high temperature
Inventor: NELIMARKKA JUHA ANTTI ELIA
IPC: F16K1/226
Filed: 1974-08-24
Abstract: The PTFE sealing ring is of U-shaped cross section with local thickening at the tips of the legs and fits into a matching groove in the valve body and is retained by the clamping flange. The lower part of the U-section is filled with a coil spring which extends around the circumference of the seal. The coils are wound so that the plane of the coil is oblique to the coil axis. A spacer ring fits between the spring and the valve body. In the sealing position the spring coils are deformed to provide a sealing pressure against the rim of the butterfly plate.

Patent DE-2506193-A1 (DE)
Title: Recovery process for additives in solvent - using distillation followed by water separator
Inventor: ZOCHE MICHAEL
IPC: D06F43/08
Filed: 1975-02-14
Abstract: Process for recovering a solvent used for washing objects e.g., metal, wood, plastic, weaves, textiles etc., where certain additives such as cleaning agents, antistatic agents, bleaches or similar are present in the solvent, consists of a distillation where the additives are carried over with the solvent and returned to the purification process. The distillation must be carried out at a temp. below the decomposition temp. for the solvent. After the distillation the solvent and additives are cooled and returned to the washing operation via a water separator. For use with washing operations to clean finished articles, esp. where chlorinated hydrocarbons are being used as solvent. Additives to improve the cleaning, the handle of fabrics or the knitting properties of yarn etc. are frequently present in the solvent and if a wound distillation is carried out, these form a difficult effluent in the base discharge. By taking them over the top with the solvent, this problem is reduced as well as recovering them for recycling in the process.

Title: Stator of helical screw pump - has spiral straps to compress elastic stator threads to compensate for wear
Inventor: BAUERFEIND HERBERT
IPC: F04C2/107
Filed: 1975-06-18
Abstract: The pump has a bearing assembly driving an overhung helical screw rotor through universal couplings. The rotor turns eccentrically in a stator which has an elastic material with a two start thread held in a steel cylinder. The steel cylinder has two helical slots each of which is bridged by a strong axial bar. Helical steel strips are placed in the slots and have end lugs which are bolted to fixed lugs on the ends of the steel cylinder. When the bolts are tightened the stator cylinder is compressed radially and in turn compresses the elastic inner material of the stator thus taking up excess clearance which has been caused by wear between the rotor and stator.
