Title: Mfr. of X=ray scattered radiation filter - comprises adhesive bonding strips transported by heated applicator
Inventor: CYROL UDO
IPC: G21K1/10
Filed: 1990-10-20
Abstract: Mfr. of an X-ray scattered radiation filter by adhesive bonding overlying individual strips, each comprising a radiation absorbing layer and a transparent layer, each strip is transported by a (pref. suction) applicator to the application position on the already assembled strips, opt. via other processing stations (e.g. for adhesive application), and the individual strips are heated to the adhesive bonding temp. The applicator is constantly heated at the bonding temp. and has a heat capacity much greater than that of an individual strip. The individual strips are heated to the bonding temp. by heat transfer from the moment of pick-up by the applicator. The major portion of the strip heating period occurs during transport prior to reacting the application position and/or during a preceding process step. The strips may consist of lead foil coated with one or more radiation transparent layers. The strips may be dispensed from a magazine or may be cut from a supply roll and may be pre-coated with adhesive or passed through an adhesive application station during the transport by the applicator. USE/ADVANTAGE - The filter is useful in medical radiography to improve image contrast. The process provides rapid heating of the individual strips to the bonding temp. without overheatin

Title: Procedure and device for boning fish - comprises two guides which pass between the ribs and the fish flesh, ensuring minimum waste
Inventor: BEHNK GUENTER
IPC: A22C25/16
Filed: 1990-11-12
Abstract: In a fish processing system, the fish ribs are freed in the customary way after the severing of the breast bone by cutting the ribs away from the flesh as far back as the back bone, and the back bone is then removed from the fish flesh by withdrawing the severed skeleton. A pair of guide elements is fitted behind the rib cutting tool and these guides are inclined towards each other and pass between the ribs and the fish flesh. A clearance between the sharp edges of these guides allows the passage of the back bone until a blunt sepg. element is reached which closes the gap and separates the back bone from the flesh. USE/ADVANTAGE - This invention comprises a procedure and a corresp. device for boning fish which are being conveyed in a head-foremost direction, by which the fish flesh is sepd. from the bones and fins. The proposed method recovers the fish flesh in its natural state and with the min. waste of usable material.

Patent DE-4100105-A1 (DE)
Inventor: FRIESE KARL-HERMANN DIPL PHYS
IPC: H01M8/1253
Filed: 1991-01-04
Abstract: The proposal is for a solid ceramic electrolyte for electrochemical purposes in which at least two standard commercial ceramic powders with different stabiliser oxide components are used. According to the invention, this provides a solid ceramic electrolyte in a simple production process which unites the advantageous properties of the ceramic powders used, especially the great mechanical strength and resistance to temperature fluctuations of partially stabilised zirconium dioxide ceramic with the good ion conductivity of fully stabilised cubic zirconium dioxide ceramic. The use of the solid ceramic electrolyte of the invention in gas sensors ensures a lower and more durable transition resistance between the solid electrolyte and the electrode.

Title: Integrated patient warning system for power operated implanted unit - maintains communication with carrier of e.g. heart pacemaker by perceptible signal pattern e.g. electrical stimulation pulses
IPC: A61N1/39
Filed: 1992-02-28
Abstract: The power operated implants include implantable defibrillators and injection pumps as well as permanent monitoring units which are suitable for the functional control of physiological and pathological performance in the organism. The integrated patient warning system is designed so that it can exert one or more differentiated warning functions.
