Title: Treatment of cholesterol-free egg yolk prods. - with alpha-amylase in membrane reactor to remove residual beta-cyclodextrin
Inventor: KOHLRAUSCH UTZ DR
IPC: A23L15/00
Filed: 1992-09-09
Abstract: Egg yolk prods. from which cholesterol has been removed using beta-cyclodextrin (BCD), are post-treated with alpha-amylose (AA) in aq. medium for enzymatic degradation of BCD. AA is from aspergillus niger, A. oryzae, Bacillus pancreas. The AA soln. is kept separate from the egg yolk prod. by a membrane during the enzymatic degradation. USE/ADVANTAGE - The process is used for removing potentially toxic residual BCD from egg yolk prods. (e.g. egg yolk or egg yolk plasma) for use in the food industry, after removal of cholesterol or its esters (which cause increased risk of arteriosclerosis and coronary heart disease) by completion with BCD. BCD is rapidly, selectively, selectively and thoroughly, removed (to give a concn. below the detection limit of 50 ppm), without loss of, or residual AA activity in, the egg yolk prod.

Title: Prodn. of metal plate which holds riveted nut - by assembling nut with rivet type underside on plate and applying high pressure to shear metal and force nut through hole formed
Inventor: MUELLER RUDOLF R M
IPC: A43D100/00
Filed: 1992-11-25
Abstract: A metal plate has at least one nut attached by a rivetting type of process, whereby the hole in the nut is closed off by a punched member. The product can be embedded in a plastic material. The figure shows a punching head (1) at the start of operations. It (1) has a ramming unit (12) to press the nut (14) when its rivet part (16) through the metal plate (18). Successive nuts are fed into position. The nut (14) has the inner thread (24) and its riveting part (16) has an internal space (29) coaxial with the thread (24). The assembly is placed in a press and a nut inserted beneath the ramming tool (12). Pressure is applied which shears through the plate and presses a 'button'' out; in turn the nut is forced down through the hole formed. The press is finally opened to release the plate and nut. The process lends itself to several variations. ADVANTAGE - The plate produced is particularly suitable for encapsulating in an injection moulding without allowing the plastic material to enter the thread on the nut.

Title: Supplying current to HF receiver from prim. or sec. cell battery - controlling PLL frequency processing circuit using control signal provided by squelch circuit
Inventor: DRAKE JOCHEN
IPC: H03L7/14
Filed: 1992-12-08
Abstract: The squelch circuit (32) delivers a first control voltage (UR1) when the reception channel is detected as free.

Title: Method of preparing for implantation or transplantation
Inventor: KLIEGIS ULRICH GEORG
IPC: A61B17/00
Filed: 1993-02-16
Abstract: The method is intended to prepare for implantation or transplantation, especially an implantation or transplantation of bones, in which a pathologically changed or injured tissue or bone region is to be removed and replaced by an artificial implant or by a transplant taken from another site or a donor. Strength and/or force transmission properties of the tissue or bone are determined without any surgical intervention in a region that adjoins the pathologically changed or injured tissue or bone region. The properties determined are considered when producing the implant or when selecting the removal site for the transplant. Volume elements of an examination volume in the tissue or bone are fixed. Parameters which are a measure of the strength properties of the tissue or bone in regions between the volume elements and directly or indirectly adjacent volume elements are determined at least for some of the volume elements. The parameters are determined by analysing computed tomograms, magnetic resonance images, ultrasound images, radiographs and/or holograms of the examination volume. At least the computed tomograms, magnetic resonance images and/or ultrasound images form a series of successive images that represent the examination volume in layers ...

Filed: 1993-03-25
Abstract: A device for severing wire windings separated from a series of windings on a winding conveyor of a wire rolling mill severs the wire windings into several sections in a wire rolling mill. The object of the invention is to allow the windings to be severed without having to technologically modify the conveyor for transporting the windings of good quality taken to the collecting shaft. For that purpose, a rolled material feed channel (1) links the winding conveyor to a scrap cutter (I) which severes the wire windings (14). The scrap cutter (I) has a housing bottom part (2') adjacent to the feed channel. The surfaces for transporting the wire windings (14) lie on an upwardly inclined plane. Several pairs of cooperating top and bottom blades (7, 8) are arranged in the bottom part (2') and in a top part (2") of the housing of the scrap cutter (I). These blades severe the wire windings into several sections. The top part (2") of the scrap cutter housing is linked to a linear drive (3) which pivots said top part against the fixed bottom part (2') of the scrap cutter housing.

Title: Manufacture of window and door frames
Inventor: STEGHERR LUDOLF
IPC: B27M1/08
Filed: 1993-04-07
Abstract: A first e.g. vertical frame element of a frame is inserted with one end on the work table (9), with the longitudinal axis at right angles to the drilling axis. The position of the element is established by a detector (13) e.g. a light barrier. Depending on this a stop (16) travels out automatically for the endface of this element. The workpiece is brought into contact with the stop and fixed at the table (9). The drillings are made at the stop side of the workpiece on the long inner side of the frame element. The drilled workpiece is released and turned 180 deg. The stop travels according to the detected position. Drillings are then made at the opposite end of the frame element.A second e.g. a horizontal frame element with its longitudinal axis directed in the direction of the drilling axis, placed against a stop to facilitate the drill passage, is clamped in position and drilled corresp. to the drill image on one of the end faces. The second frame is turned 180 deg. after being released. With the side exchanged the element is pushed against the stop and secured on the working table. The other endface is drilled to correspond. Dowel pins are then inserted in both endfaces of this second frame element.
