Patent DE-3214337-A1 (DE)
Inventor: STROETMANN MICHAEL
IPC: A61L27/60
Filed: 1982-04-19
Abstract: A resorptive sheet material for closing and healing wounds substantially consists of a glycoprotein matrix containing substances which cause and, respectively, are conductive to the coagulation of blood including fibrinogen and thrombin. The sheet material is dry and of multi-layered structure, wherein at least one layer is free from thrombin and contains in the glycoprotein matrix thereof the fibrinogen in a substantially homogeneously distributed form, and at least one further layer is free from fibrinogen and contains in the glycoprotein matrix thereof the thrombin in a substantially homogenenously distributed form. The glycoproteins coming into consideration, above all, are non-linked fibrin, fibrin fission products, collagen, globulin, myoglobulin, casein and/or albumin. Preferably, at least one of the layers, especially one or both outer layer(s), contains fibroblast cells present in dry state and/or agents conducive to the growth of the fibroblasts and their spreading-in, especially chondroitin sulphate. For the production, fibrinogen is added to a thrombin-free, predominantly aqueous solution and/or suspension of the glycoprotein and said solution and/or suspension is processed to form a sheet-material layer, and onto the full surface of this layer at least one further layer is applied which, in its turn, has been obtained from a further, fibrinogen-free and thrombin-containing solution and/or suspension of the same or of another glycoprotein. In particular, a solution and/or suspension of one composition is applied onto an inert surface, where it is subjected to deep-freezing, and onto the resultant ice-layer surface, when still in the deep-frozen state, a solution and/or suspension of different composition is applied and subjected to deep-freezing, and, finally, all layers are jointly subjected to lyophilization.

Patent DE-3301421-A1 (DE)
Title: Holding device for firing ceramic moulded parts
Inventor: WITTEKIND HERBERT
IPC: F27D5/00
Filed: 1983-01-18
Abstract: An increase in performance and cost-effectiveness in firing ceramic, preferably flat, moulded parts by means of firing aids which, as holding firing devices, are respectively passed into the kiln chamber in a relatively large number on suitable travelling carts, is effected by holding devices made of temperature-resistant steel profiles with at least 3 vertical supports which are welded to corresponding horizontal radial webs or radial knobs to receive the moulded parts. Thermal deformations of the holding device during the heating and cooling process of the moulded parts and of the holding means carrying them are prevented, especially by a suitable choice of the profile thicknesses, both of the radial webs and of the vertical supports, and also by the tangential weld connection of the radial webs or knobs.

Title: Bearing for wheel set guide rods in axle bearings of a rail power unit
Inventor: MAUTNER FRANZ
IPC: B61F5/32

Title: Turning and adjusting tool for workpieces with a cylindrical circumferential surface, in particular for track rods on motor vehicles
Inventor: BLUME HARALD ING GRAD
IPC: B25B27/00
Filed: 1983-09-20
Abstract: Arranged on a shank (4b) is a head piece (4a) on which a clamping device is arranged which acts on the periphery of the workpiece (5) and is rotatable about the longitudinal axis of the workpiece. The clamping device has two toothed discs (1, 2) which are arranged coaxially to one another, are rotatable towards one another and with one another, are driven at their periphery and are guided on one another and on the head piece. Each toothed disc (1, 2) has a recess (1a, 2a) extending radially like a slot from the outside to the inside beyond the centre of the toothed disc and having a rounded-off inner end. The width of the recess and the radius of the inner end are adapted to the diameter of the workpiece (5). When the toothed discs (1, 2) are rotated towards one another, a workpiece (5) guided by the recesses (1a, 2a) is enclosed after a predetermined angle of rotation and it is clamped in place along its entire periphery. The workpiece is then adjusted by rotating the two toothed discs (1, 2) in the same direction.
Patent DE-3340782-A1 (DE)
Inventor: KLINGLER OTTO DR ING DR
IPC: G01B7/02
Filed: 1983-11-11
Abstract: This device has a measurement value pick-up which consists of a stationary part (1) as scale and a parallel part (2), which can be displaced over its surface at a short distance, as scanning unit. The mutually opposite areas of the scale (1) and of the scanning unit (2) are provided with capacitor foils 5,6,7,8,9. The mechanical quantity to be measured results in a change in area of one capacitor, the resultant change in capacity acting as a variable capacitive reactive impedance in a circuit which changes the phase angle of the electrical signals. If the capacitor area (5,6,7,8,9) is appropriately shaped, a linear function is obtained between the mechanical quantity to be measured and the phase angle of the signals.

Title: Method and device for mechanical milking dry of animals
Inventor: BILLHARDT JOERG
IPC: A01J7/00
Filed: 1983-11-28
Abstract: The invention relates to a method and a device for the mechanical milking dry of animals, in particular cattle, which can be used in all types of suction milking. The object of the invention is, with relatively low outlay on apparatus, to achieve rapid and as complete as possible milking dry with a reduction of the manual work. The aim of the invention is, during milk extraction, to bring about a favourable degree of opening of the transition between udder and teat cistern depending upon the milk flow. The aim is achieved in that, starting from application of the milking cups, there is put into effect on the milking machine, depending upon the milk flow and approximately inversely proportionally to this, a pulling force, the size of which is between 0 and approximately 80 N. The device has, preferably arranged on the milk collecting piece, a pneumatic drive which is provided with a flow control device, acted upon by a milk flow transmitter, for at least one working medium (Fig. 2). <IMAGE>
