Title: Brake test stand for motor vehicles
Inventor: SCHLEGEL WILLI
IPC: B60T17/22
Filed: 1987-01-17
Abstract: A brake test stand for motor vehicles has two roller sets for each axle of the motor vehicle in the axial direction at a distance from but adjacent to one another, which roller sets are mounted in carrier pairs (2, 5) and each consist of three rollers (3, 6, 14). At least one (14) of the rollers (3, 6, 14) of each set can be pressed from below, by being moved relative to at least one of the other rollers by means of a lifting device (10), with adjustable force which is dependent on the other lifting devices against the wheel supported by the rollers (3, 6, 14) and is coupled to a drive device and/or brake device (15, 32). The driven rollers (14), which are appropriately arranged, of the two roller sets which are assigned to the same axis are arranged on a common shaft (11) which connects them so that they are fixed in terms of rotation. All the common shafts (11) are coupled to one another via a transmission (16 17, 18) which forcibly brings about their synchronous running. One of the common shafts (11) and one of the free-wheeling rollers (3, 6) of each roller pair is assigned in each case a speed-of-revolution sensor (21, 23) with a speed-of-revolution display device (22, 24). <IMAGE>

Title: Process for the cultivation of HIV-2 viruses, cell cultures suitable for this purpose, and diagnostic agents for detecting HIV-2 viruses and process for their production
Inventor: KURTH REINHARD PROF DR
IPC: C12N5/02
Filed: 1987-04-11
Abstract: The invention relates to a process for obtaining HIV-2 viruses in which a culture of permanent T-lymphocytes or of lymphocytes from cord blood is mixed with serum or lymphocytes of patients infected with HIV-2. This cocultivation is continued under suitable conditions. When cord blood lymphocytes are used, a mixing with permanently growing T-lymphoma cells is carried out after 14 days. After infection of the infectable cells there is an adequate measurable virus concentration in the culture supernatant so that the viruses can be isolated and investigated in a conventional way. Also described is a process for detecting HIV-2 antibodies in samples, in particular blood samples, in which a cell-free sample is subjected to an antigen-antibody reaction with a viral antigen obtained by the abovementioned process, and the extent of this reaction is determined in a conventional way, as well as agents for carrying out this process which contain an appropriate HIV-2 virus preparation as well as reagents for detecting HIV-2 virus/HIV-2 antibody complexes.

Title: Optical arrangement with radial and axial temperature compensation
Inventor: EBERHARD VOLKER DIPL ING
IPC: G02B7/18
Filed: 1987-05-02
Abstract: The invention relates to an optical arrangement with radial and axial temperature compensation and may be applied in those cases, where optical systems are exposed to high temperature stresses. The object, to allow no relative axial and radial deviation of the optical components under changing temperature influences, and at the same time to fix the positions of low depth-of-focus receivers with low stress, is solved by inserting the optical components into a hollow cylinder arrangement on a construction of struts, whose material constants are so chosen, that length expansions which occur are counter-compensated.

Title: Method and apparatus for the marking of tubes
Inventor: RAASCH HANS
IPC: B65C3/00
Filed: 1987-10-03
Abstract: Run-on bobbins, when removed from bobbin-producing machines, are often provided with markings or labels, so that the material, yarn fineness and production machine can easily be identified. This marking takes place, as a rule, during the removal of the bobbins from the bobbin-producing machine. However, the removal of the bobbins has to be carried out quickly, so as not to detract from the production time of the machine. A new method and apparatus for the marking of tubes are therefore presented. In the method according to the invention, the tubes are assigned unmarked to one of the spinning/winding or winding machines, and marking takes place between extraction from an intermediate magazine and before the feed to individual winding stations. A marking is made on a carrier (4), to be bonded adhesively to the tubes (1), by means of a marking apparatus (100; 200) or directly onto the cavity wall on the inside of the tubes. <IMAGE>

Title: Method and apparatus for joining a metal-ceramic heat shield to a piston, engine valve or the like by a casting technique
Inventor: STIERMANN ERWIN DIPL ING
IPC: F02B3/06
Filed: 1988-02-25
Abstract: The proposal is for a method for the production of a reciprocating component of an internal combustion engine subjected to combustion heat with a thin, metal-ceramic heat shield. In this method the heat shield (1) is, before casting on the component body, placed face downwards on a recess (12) provided in the casting mould (10,11), with sealing contact all the way round at the edges only, then curved slightly into the recess (12) by the action of a force and, in the process, prestressed, and held in this curved shape by an applied suction force. The component body is then cast onto the heat shield (1), the curvature of the heat shield being maintained by the suction force until the material of the component body solidifies. This curvature is maintained during the use of the component, even at the operating temperature, and is preferably just great enough to ensure that the internal stresses in the heat shield caused by the temperature gradient between the front side (2) of the heat shield, subjected to combustion heat, and the cooler rear side (3) of the heat shield and the resulting differences in expansion can be largely relieved. Protection also extends to the apparatus for carrying out the method and to the component produced in this way. <IMAGE>

Title: Vehicle antenna in the form of a rod
Inventor: SCHUSTER HUBERT
IPC: H01Q9/30
Filed: 1988-07-05
Abstract: The radio reception and car-radio antennas which are provided for installation in a motor vehicle have noise levels in the present generation of vehicles, especially medium class or higher class vehicles, which have been found to be unpleasant and are audible in the vehicle passenger compartment, particularly when driving at high speeds. In order to reduce and to suppress this noise, which is produced by the antenna, the invention provides for at least one circumferential helix (7) to be constructed on the antenna (1) and/or on individual antenna sections (1' to 1'''). The helix (7) has a pitch of 1 to 10 times the antenna diameter, a thickness and/or height of 0.05 to 0.5 times the associated antenna diameter. Even when one helix (7) is sufficient, very favourable values result when using three helixes (7) which are circumferential located offset with respect to one another. The antenna in the form of a rod is suitable for radio antennas and directional-radio antennas on motor vehicles. <IMAGE>
