Title: Hooked tension rod for sawmill blade - has hinge or slot allowing flexure after saw blade has been removed
Inventor: FELDE JOERG
IPC: B27B3/30
Filed: 1975-11-11
Abstract: The saw balde is hooked to the tension rod, and then tightened in its frame by driving a wedge between a stop on the rod and a fixed part of the frame. When the blade is removed, the rod is free to move. To prevent it from sliding back and catching in the frame, and getting bent and twisted, the rod is made flexible at a hinge positioned between the hook that takes the saw blade and the tightening wedge. The rod can be made in two parts, one held by a pin in the forked end of the other. Alternatively, the requisite play is given by pin sliding in a slot.

Title: Kallikrein-trypsin inhibitor purification - by treating with non-specific proteases to remove ballast proteins and polypeptides
Inventor: SCHUTT HERMANN DR
IPC: C12N11/02
Filed: 1976-04-09
Abstract: In a new process for removing inactive ballast proteins and ballast polypeptides from solutions of kallikrein-trypsin inhibitor (KTI) of different degrees of purity, the solutions are treated with non-specific proteases (which may be in immobilized form) which do not inhibit KTI, and the resulting peptides and amino acids are subsequently separated from the KTI by conventional physical methods. Highly concentrated infusion solutions of KTI are used in the treatment of pancratitis and states of shock. Such solutions should be as free as possible from inactive proteins. The process is technically simple to carry out, and gives purified KTI in quantitative yield. In an example, crude KTI (193.3 kallikrein inactivator unit/mg protein) was incubated at 40 degrees C with proteinase K immobilized on an oxirane-acrylamide gel. KTI with an activity of 201.3 kallikrein inactivator units/mg protein was obtained (enrichment factor 1.04), When starchimmobilized subtilisin was used as the protease and enrichment factor of 3.2 was obtd.

Title: Seal suitable for oil pumps - in which one sealing ring is scored to create pumping action which prevents leakage
Inventor: NYLYKKE HANS PETER GLUD
IPC: F16J15/34
Filed: 1976-06-12
Abstract: Sealing ring for a gliding seal, esp. for oil pumps, uses a thrust ring and a rotating ring, one being made of metal the other of carbon. The novelty is that in the working surface of the metal thrust ring inclined radial scores are used to create a pumping effect acting against the liq. pressure along the surface of the gliding seal, the free cross section of the scores being so small that no leakage occurs when the pump is stationary. The scores are pref. ground in to give a roughness of 1-2 mu m and the surface is coated with phosphate 2-5 mu m thick. The scores may be uniformly curved or straight. Seal effectively prevents leakage of an oil pump, e.g. in oil heating installations in a room where leakage cannot be tolerated. The seal is easy to make.

The small end of the case extends around the part of the hose adjacent the coupling part. The conical shape of the case ensures that the coupling part can slide over obstructions without difficulties due to sharp edges of the coupling part (2). The case may be a separate plastics component assembled on the coupling part, or it may be integral with the coupling part.

Abstract: Appts. comprises a straight tubular, unperforated housing with an inlet at one end and an outlet at the other. In the housing is a separator which is a series of parallel rods with centres on a circle centred on the house axis. The rods are inside a circle smaller than the housing dia. They run parallel to the axis. The distance between the centres of adjacent rods is constant. An annular space is thus formed between the rods and the housing. The feed enters inside the separator, and the outlet also connects inside the separators. The side stream is taken from the side of the housing and comes from the annulus. Used in the analysis of liquids contg. solids of varying size, esp. effluent, where large solids would, block the equipment for treatment or analysis. Separator is self cleaning and functions for months without supervision.
