Patent DE-3513990-C1 (DE)
Title: Exchanging device
Inventor: BALFANZ KARL-HEINZ
IPC: H01Q1/16
Filed: 1985-04-18
Granted: 1986-11-13
Abstract: The invention relates to an exchanging device for the exchange of at least one portion of a tensile-force-transmitting, multi-membered, linearly aligned structural part (24), in particular a saddle frame in antenna arrays, having at least one clamping device which can be fastened on the structural part (24) in order to bridge the portion to be exchanged. A relatively lightweight structure which is simple in terms of design and easy to mount is achieved in that, on either side of the portion, to be exchanged, on the structural part (24), there are provided mountable fastening elements which are connected to one another by at least one tie rod (30). The tie rod (30) is braced by clamping means. Screw clamping cylinders (33), for example, are suitable for this purpose. <IMAGE>
Patent DE-3621241-C1 (DE)
Inventor: GRAF GUENTER DR-ING
IPC: F16J15/32
Filed: 1986-06-25
Granted: 1987-06-25
Abstract: In a method for manufacturing a sealing ring with a sealing lip, the material forming the sealing lip is fabricated in plastically deformable condition into the shape of a column-like hollow body. Prior to solidification, the column-like hollow body is twisted between axially spaced cross-sectional planes. This forms return elements with hydrodynamic action. Subsequently, the hollow body is solidfied and its diameter is enlarged axially outside the region of the sealing lip and it is then secured in a sealing ring housing.

Title: Method for fitting a coupling element to the end of an electrical cable (line, lead)
IPC: H01R43/24
Filed: 1986-07-16
Granted: 1987-10-01
Abstract: A method is specified for the injection moulding of an electrical coupling element on a cable (1). The conductors (14) of the cores (2) are connected to contact elements (4) which are arranged in holes (6) through a carrier (3). The openings of the through-holes (6) on the cable side are sealed by tubular elements (11) which are seated firmly on the cores (2) and rest tightly against the wall of the through-holes (6). The injection-moulding material of the protective body (5) cannot pass into the through-holes (6) and hence cannot pass onto the contact elements (4). <IMAGE>
Patent DE-3734714-C1 (DE)
Title: Device for the preparation of comminuted bone grafts
Inventor: TESSIER PAUL DR
IPC: A61B90/00
Filed: 1987-10-14
Granted: 1988-12-08
Abstract: The invention proposes a bioosteomicrotome which is seated on the workbench by means of a substantially slip-proof baseplate and whose cutting cylinder is operated by a manual lever which can be pivoted about 180@. A directional locking mechanism provided between the manual lever and the cutting cylinder ensures that the cutting cylinder is only operated on pivoting of the manual lever in the direction of the user and the baseplate, whereas the cutting cylinder remains in its position on movement in the opposite direction. For reception of the comminuted graft there is a reception vessel which can be pushed into the cutting cylinder. Improvements made on the stopper are also intended to improve handling and positional reliability of the device during operation.

Patent DE-4316963-C1 (DE)
Title: Manipulation device for golfers, especially for the insertion of a tee and placement of a golf ball on the tee
Inventor: OECKL OTTO
IPC: A63B57/00
Filed: 1993-05-21
Granted: 1994-12-01
Abstract: The placement of the golf ball on the tee inserted into the ground, the picking-up of the tee which usually lies in front of the driving position, and the picking-up of the ball after putting out often causes difficulties for a number of golfers - mainly older players suffering from back or circulatory problems. Teeing up on hard ground is particularly wearisome. The invention provides protection for a device with the aid of which bending is avoided in all these situations described. The ball can be teed up by means of the controlled clamping jaws, the tee lying on the teeing ground can be picked up by the pincer movement of the jaws, as can the ball after it has been holed. The device can also be used for picking a ball out of water. An important advantage of the invention resides in the fact that the device can be laid down at the same point where it is used, whether on the teeing ground or on the green.
Patent DE-4319988-C1 (DE)
Title: Method for handling electrophoresis gel sheets
Inventor: BENDER BERNHARD
IPC: G01N27/447
Filed: 1993-06-17
Granted: 1994-12-22
Abstract: The method enables large electrophoresis gels to be clamped using a clamping apparatus, so that different types of manipulations, such as for example changes of buffer and staining can be carried out after the electrophoresis. Hitherto, there has been no suitable and reproducible method for rapidly and reversibly mechanically fixing an electrophoresis gel sheet so that methods having various disadvantages have been used, such as e.g. sticking the gel to the support plate or use of cost-intensive support films. A clamping apparatus according to the method comprises a base plate (1) and a frame (2) which is fixed to the base plate using a clamping apparatus (6, 7). An electrophoresis gel (5) lying on a support plate is clamped between base plate (1) and frame (2) after electrophoresis has been carried out. The frame (2) lies on the gel sheet (5) on all sides and forms, with the gel as a base, a chamber (8) only open at the top, into which various liquids can be added and from which they can be removed again. A seal (3) underneath the frame prevents damage to the gel sheet and seals the chamber (8). The method can be used in all specialist areas where large electrophoresis gels are used (biology, medicine etc.) and a method requires manipulations on the gel sheet after electrophoresis has been carried out. <IMAGE>

The wall and/or the means for increasing its surface area are provided with a hydrophilic coating having at least one of the following properties : (a) a strong adhesion to the wall surface ; (b) providing cover for essentially the entire heat exchange surface area ; (c) a maximum thickness of 50 microns ; (d) a thermal resistance which is small in relation to the total thermal resistance in the heat exchange path between the heat exchange surface and the medium flowing along it ; (e) a hydrophilicity sufficient for a film of water to be spread over the coating surface when it comes into contact with moisture, optionally in combination with the formation of a buffer supply of water stored in capillaries in the coating ; (f) a low surface roughness so that the medium flowing over it is subjected only to a negligible flow resistance ; (g) a low susceptibility to thermal or (bio)chemical degradation, erosion, microorganism growth and fouling ; and (h) morphological, chemical and physical homogeneity. The coating is applied via a chemical method in which each heat exchange surface is initially activated using a chemical and/or mechanical treatment and then the coating is formed by a chemical reaction from an aqueous solution.

Granted: 1995-02-27
Abstract: FIELD: ferrous metallurgy. SUBSTANCE: ore portion of charge and cock are fed to hoppers of loading device and cock weight in the feed is changed depending upon change in ore portion density of the charge by a value, specified by expression as follows: ΔK = 0,01·K aver ·(ρ pres -ρ aver )α ,, where K aver  is a value of cock weight in the feed at adopted averaged iron content in ore portion of the charge; ρ pres  - is present density of ore portion of charge; ρ aver  is density of ore portion of the charge at adopted averaged iron content; α is slope tangent of linear function in dependency of iron content in ore portion of the charge on its density. Stabilization of furnace heat state is achieved at the expense of prompt definition of density of ore portion of the charge, and hence, by direct prompt definition of DK in charge hoppers by pycnometry using gas fed to the hopper before charge pouring down. EFFECT: improved smelting by changing cock weight.
