The process for producing the complex comprises treating the epithalamo-epiphyseal tissue with an organic solvent, disintegrating the tissue, extracting the complex with 1 to 10 percent aqueous acetic acid in the presence of zinc chioride, separating the precipitate and the supernatant, the complex of polypeptides is then precipitated from said supernantant with an organic solvent. This precipitate is washed with an organic solvent and dried, the complex is water-extracted from the dried precipitate, the thus obtained solution is then separated from the precipitate, filtration-sterilized and lyophilized. The complex affects the neuro-endocrime system, acts as an immunostimulant and as an inhibitor of hormone-dependent tumours.

Patent DE-3828629-A1 (DE)
Inventor: RAMM KARL-HEINZ
IPC: H01F41/08
Filed: 1988-08-19
Abstract: The invention concerns a device for winding wire onto annular core in layers between layers of tape. The annular core is mounted so as to rotate about its annular axis. A wire-winding head winds wire onto the rotating core. The inner diameter of the annular core is just large enough to admit the wire-winding head. At the same time, a bandaging head (2) arranged along the annular core at an angle of 90 DEG  to 120 DEG  in the direction of rotation, starting from the wire-winding head (1), winds tape onto the core (3). In this way, wire and tape can be wound by machine onto the core from beginning to end.

Title: Mounting rack for flameproof switching installations
Inventor: BERGER MATTHIAS DR ING
IPC: H02B1/28
Filed: 1988-10-13
Abstract: In the previously known flameproof switching installations, the switching devices are arranged in individual withdrawable inserts which are connected, inside the pressure-resistant housing, to the external connections via costly cabling which occupies a large amount of space. In the case of the new mounting rack, the installation cost and the space requirement for the cabling within the housing and on the mounting rack are intended to be reduced. The mounting rack is designed to accommodate a plurality of switching devices and additional devices, the connections of the switching devices on the outlet side being passed to a load bus which is integrated in the baseplate of the mounting rack in an electrically insulated manner. The mounting rack can be installed especially in pressure-resistant housings since only external cables still need to be connected to the unit. <IMAGE>

Title: Coil former for dynamic loudspeakers for reducing eddy current influences
Inventor: KUEPER MARTIN DIPL ING
IPC: H04R9/04
Filed: 1989-02-14
Abstract: The invention relates to a loudspeaker voice coil former for dynamic loudspeaker systems of metal, which is divided into narrow strips in the axial direction in the area of the voice coil winding, in which arrangement the resultant intermediate spaces can be kept very narrow and are slightly longer than the height of the coil winding. Laying out such a coil former results in a shape which is similar to a cone, that is to say the intermediate spaces between the strips are open at the bottom end. The width of the metal strips determines the remaining damping effect of the coil former. If the strips are sufficiently narrow, the eddy current formation can be reduced in such a manner that the rise time of a loudspeaker is no longer determined by the damping of the coil former but only by the time constant inherent in the coil, disregarding other effects. This means that the coil former behaves like a nonmetallic coil former with respect to the damping, while simultaneously retaining all advantages of a metallic coil former with respect to heat dissipation. In addition, the coil former neck can be constructed as a closed cylinder if the laminations are made sufficiently narrow and long, as a result of which a strong eddy current brake is produced in the form of a short circuit ring which protects the loudspeaker against bottoming in the case of mechanical overloading (Figure 2). <IMAGE>

Patent DE-3919199-A1 (DE)
Inventor: HENGERER FRANK DR
IPC: C21D9/40
Filed: 1989-06-13
Abstract: A rolling-bearing race member 1, 2 comprises a supporting member 6 of low-alloy steel and at least one race ring 5 of through-hardening rolling-bearing steel. The supporting member is rigidly connected to the race ring or rings by pressing on and/or shaping to form a one-piece race member. This race member is subsequently heated to a hardening temperature, held at this temperature for the austenizing of the rolling-bearing steel of the race ring or rings, and finally quenched in oil, salt or water to achieve a martensitic structure of the rolling-bearing steel with a hardness of 58 to 64 HRC. In order that the finished race member may have little residual stress in the transition region, a steel having a carbon content of 0.15 to 0.40% is used for the supporting member, which steel is likewise austenized when the race member is held at the hardening temperature and is likewise converted into a martensitic structure when the race member is quenched. Hollow bearing rollers can be made by a similar method. <IMAGE>

Title: Preform chemical vapour deposition process - for optical fibres by specified planetary gear drive
Inventor: MOETTER ADOLF
IPC: C03B37/018
Filed: 1989-08-05
Abstract: When a glass tube, used as the preform of an optical fibre, is to be coated internally with core and sheath layers, a furnace is moved downwards for the deposition cycle slowly and upward fast for the return. This is carried out by a motor with a planetary gear and a clutch at the gear input and gear output. One of them blocks a sun pinion for the slow speed and the second blocks a sun pinion for the fast speed. Pref.  planetary gear has a motor (10) with a clutch for the sun pinion (12) at the input. A clutch (17) acts on output sun pinion (13) which is joined by planet wheels (14,15) to the input sun pinion. For a fast travel, the two clutches (11,17) are actuated to drive the shaft (18) by the gears (14,15,16). For the slow travel, they are controlled to fix the input sun pinion for the gears (14,15) to revolve around it and to drive the shaft (18) by the pinion in the reverse direction and slowly. ADVANTAGE - Provides a uniform and easy motion with a uniform high torque.
