Title: Pressure plate for extrusion pressing of metal - space between pressure plate and adaptor in press punch for wear ring which deforms under pressure reducing play against barrel
Inventor: KOEDDERMANN HANS OTTO
IPC: B21C26/00
Filed: 1990-01-20
Abstract: Pressure plate is for the punch of a metal extrusion press. The plate is smaller than the press punch or the adaptor in which the plate is held. Between the pressure plate and the adaptor is a wear ring whose outer edge has a thickened section which moves with the pressure plate and also enlarges the working surface of the latter. The wear ring has a tapered surface on the side facing the adaptor which creates a free space for deformation of the wear ring. In operation within a barrel the dia. of the pressure plate increases and eliminates play between the wear ring and the barrel wall. USE/ADVANTAGE - Used in the punch of a metal extrusion press and reduces the gap between punch and barrel wall to eliminate back flow and permit higher pressure operation.

Title: Pore-building in cement - using gas producing material coated with inactive layer to delay gas formation when components are initially mixed
Inventor: MANSFELD LOTHAR
IPC: C04B22/04
Filed: 1990-03-28
Abstract: Porosity formation in cement is carried out using a powder material which chemically reacts with a component of the cement to produce a gas. In order to stop the reaction taking place immediately upon mixing, the powder material is provided with an inactive coating which is removed in a controlled fashion during the prodn. process. The gas-forming material is a metal or Si which is easily oxidised in an oxidising atmosphere at high temp. or in an irradiated oxidising atmosphere. The concn. and/or working time of the oxidising agent is chosen depending on the required inactive period of the powder. Alternatively the powder may be coated with a saponifiable fat, oil, resin or wax. The treated powder is stored by packing under a protective or vacuum atmos. The pref. pore-forming agent is a silicide, esp. ferrosilicon. ADVANTAGE - The mixed cement does not have to be quickly used and thereby can have a wide range of enployment.

Patent DE-4120358-A1 (DE)
Inventor: SAALBACH KURT DIPL ING
IPC: F16J3/04
Filed: 1991-06-20
Abstract: The invention relates to a load-dependent twin braking power regulator, the switchover pressure of which is determined by a lever (24) via a rocker component (17).

Title: Immuno-sensor for sensitive detection of low mol. wt. antigen - uses displacement of enzyme conjugate, reaction with substrate and prod. amplification on bio-sensor, used esp. for drugs, herbicides and explosives
Inventor: SCHELLER FRIEDER PROF DR
IPC: G01N33/543
Filed: 1991-08-13
Abstract: Immunosensor device for detecting antigens (Ag) of mol. wt. below 2000 comprises 1 or 2 enzyme-immunoreactors (IR) and a biosensor coated with at least one biocatalyst. The measurement soln., which contains a substrate S for the enzyme conjugate used in IR and opt. co-substrates for biocatalyst, flows from the IR to the biosensor. Also new is a method using this device. The sample is added to IR contg. an immobilised Ag-specific antibody (Ab) which, before measurement, is satd. with an enzyme-configurate (EC) of Ag. Ag in the sample displaces EC and opt. this is bound in a second IR or by Ab on the biosensor surface. After leaving the first IR, the sample is mixed with S and the resulting product amplifies by the biosensor. USE/ADVANTAGE - The method is used to detect drugs, herbicides and explosives. Coupling of IR with a biosensor amplifies the detection signal and so increases sensitivity. The method is used e.g. to detect traces of Ag in the air. The increase in sensitivity is 10-20 times using one enzyme or 100-1000 times using two enzymes, so incubation time can also be reduced
