Title: Connecting device for coaxial cables
Inventor: MARGREITER HANS
IPC: H01R13/585
Filed: 1987-12-22
Abstract: Particularly in the case of connecting terminals for coaxial cables, the problem exists that the tension forces which are introduced on to an inner conductor lead to the inner conductor being pulled back with respect to the outer conductor, and an existing contact thus being interrupted. In order further to improve a stop element, which is provided for this purpose, in the manner of a locking/spreading element (25) in accordance with the Main Patent Application P 3708493.3-34, it is provided that the at least one latching/locking finger (29), which projects into the through-opening (27) for the inner conductor (17), is constructed at least approximately or to the same extent in the form of a tongue, trapezoid or rectangle. The connecting device is particularly suitable for coaxial cables for broadband (wideband) communications networks. <IMAGE>

Title: Method for characterising optical properties of semiconductor lasers, and device for carrying out the method
Inventor: MOZER ALBRECHT DR RER NAT
IPC: G01R31/26
Filed: 1988-02-01
Abstract: In the production of semiconductor lasers or laser chips, several hundred individual lasers are located on one laser wafer. In order to characterise their optical properties, the wafer must be split and each laser or each laser chip must be optically tested individually. This method is very time consuming. The method represented here and the device for carrying out the method permit the optical properties of lasers or laser chips to be tested directly on the wafer. For this purpose, there are measured at the electric input of the lasers noise spectra from which conclusions are then drawn concerning the optical properties such as, e.g., mode spectrum, threshold current, quantum efficiency, relaxation frequencies and line width. The optical properties of transmit modules can be optimised in the same way. The characterisation based on purely electrical measurements can be used to simplify and automate the production of semiconductor lasers and optical transmit modules. <IMAGE>

Title: Method for the detection of the damping value of axle shock absorbers built into motor vehicles and device for carrying out the method
Inventor: SCHARBRODT PAUL DIPL ING
IPC: G01M17/04
Filed: 1988-08-02
Abstract: The invention relates to a method for the detection of the damping value of axle shock absorbers built into motor vehicles and a device for carrying out the method. According to the invention, axle shock absorbers (12) already built in may be tested in respect of their functionality in a simple and reliable way by biasing the axle springs (11) artificially and measuring the recoil amplitudes of the bodywork (17). The test is carried out axle-by-axle. Since the recoil vibrations are smaller in the case of intact shock absorbers than in the case of defective ones, the recoil distance determinable according to the invention forms a usable and reproducible standard for the efficiency of built in shock absorbers.   Because of its simple and cost-effective construction, the acquisition of this test device is also possible for small workshops. By using the device on a broad basis, account could be taken of the need for intensified monitoring of the roadworthiness of motor vehicles. <IMAGE>

Title: Regeneration and prepn. of extended asphalt - by special bitumen emulsion increases capabilities of cold mix technique
Inventor: MUNTZER EMILE
IPC: E01C7/18
Filed: 1989-06-09
Abstract: This is a method for the regeneration and preparation of extended asphalt with oils and/or acidified bitumen whose basis is the crude-oil distillation of petroleum. The bitumenis in the form of a cation process emulsion developed from an anion parent emulsion. Protein substances are added to the original anion emulsion, and the soap is extracted as an indication of the anion parent emulsion by the addition of precipitating salts such as magnesium sulphate or acids.  A number of features and variants are claimed.  The emulsions used have a binder constituent qualitatively identical to the bitumen used in the hot-mix technique.  The addition to the bitumen and emulsifying water is modified so that a material for mixing, fully equivalent to the hot-mix material, can be prepared, and the emulsion, in its formulation and adapting capabilities, offers wider possibilities to the material to be mixed. USE/ADVANTAGE - The method increases the capabilities of the bituminous cold-mix technique.

Title: Pump for thermoplastic melt - is gearwheel type and feeds polymer by universal coupling drive in bore so that melt provides lubrication and prevents running dry
Inventor: HERTELL SIEGFRIED DIPL ING
IPC: F04C15/00
Filed: 1989-09-22
Abstract: A pump for thermoplastic melts has a shaft which is fixed to a drive shaft through a universal coupling, where the coupling is a piston in the bore of a housing. The charge of fusible polymer is between the coupling and its housing, and the melt is a bearing for the coupling member. The gearwheel pump shown has flat housing plates (1-6), of which (1) and (5) plus (3) are bored for the shafts (7, 8), the latter (8) being hollow. The others (2, 4) are so-called "spectacle" plates and hold meshing pairs of gear-wheels (11, 12 and 9, 10); of these (11) and (9) are spring-loaded on to the pump shaft (7).  Melt flows out from the bores (13, 14), one (13) being through the shaft (8). The housing of the coupling is the bore (18) in the plate (6); it (18) accepts the piston member (16) and the polymer charge (23). The polymer surrounds the member (16) and is on both faces. The length of the polymer charge is thus the axial length of the bore. Hot melt provides lubrication between the fixed housing (6) and member (16). ADVANTAGE - The pump (e.g. for continuous action with melts for spinning) provides independent bearings for its coupling and housing, and prevents running dry.
