Patent DE-3002264-A1 (DE)
Inventor: SCHULTE WOLFGANG
IPC: B29C45/78
Filed: 1980-01-23
Abstract: Apparatus for injection moulding thermoplastic material is disclosed wherein a heavy-duty sprue bush is heated along a substantial portion of its length to keep the thermoplastic material from solidifying during interruptions in the moulding cycle. The apparatus provides for minimal contact between the heated sprue bush and the moulding die to prevent heat transfer between them. This is achieved by maintaining an air gap between the bush and the die except at points where the thermoplastic material passes into the moulding cavity. Sprue runners oriented generally parallel to the mould joint line are aligned with cavity injection openings which are similarly oriented. These injection openings pass through a thin wall of the mould that extends generally perpendicularly to the joint line such that when the moulds are open, the sprue is cleanly severed from the moulded article.

Title: Blood flow measuring device application equipment - has guide ring determining alignment of instrument with standardised skin puncture
Inventor: FEHLAU ROBERT
IPC: A61B5/15
Filed: 1980-06-14
Abstract: A puncture of standardised dimensions (41) is formed in the skin (40), after which a flow vessel (21) for a liquid flushing agent is placed on the wound, the passage (22,23,24) in this vessel being open to the wound for part of its length. Thus the blood emerging is drawn by the flushing medium into a measuring instrument, where the content of blood ingredients is continuously measured. A guide ring (31) is fixed concentrically round where the wound is to be made and the instrument is fitted onto the ring at right angles to the skin surface. It is in an angular position, such that guides (12,32) on it and the ring engage positively together, thus determining the angle of the cutter blade (11) on the instrument. After removal of the blade, the bowl is fitted in place, its guides (26) engaging with those (32) on the ring. Thus the open portion (23) of the bowl passage is brought into line with the wound.
