Patent DE-4007534-C1 (DE)
IPC: B22F9/04
Filed: 1990-03-09
Granted: 1991-08-29
Abstract: A process is disclosed for producing SE permanent magnets. The ground constituents of the basic alloy are wet-ground in solvents, the wet-ground laitance is dryed, aligned in a magnetic field and pressed into blanks, the blanks are sintered into raw magnets and the permanent magnets produced from the raw magnets are magnetized. In order to improve this production process, the laitance is pressed in a wet press into blanks, while being aligned in the magnetic field, the pressure required being half the pressure required for dry-pressing and the aligning magnetic field being 50 to 60 % of the magnetic field used to align dry pressed blanks. The wet-pressed and aligned blanks are sintered into raw magnets.

Patent DE-4321236-C1 (DE)
Title: Multiphase electrical machine having a winding made of flat moulded conductors
Inventor: HILL WOLFGANG
IPC: H02K3/12
Filed: 1993-06-25
Granted: 1994-08-25
Abstract: Known bar windings and moulded coils are bent from conductor bars having a constant cross-section and therefore utilise the winding overhang space only inadequately. Furthermore, long connecting paths result in comparison with the step width because of the bending radii which have to be taken into account - particularly in the case of machines having a large number of poles, as a result of which the weight and losses are increased. Moulded conductors according to the invention are produced integrally, without any bending radii, in accordance with their final shape. They vary their cross-section in the winding overhang and thus achieve good space utilisation and short connecting paths. Successive moulded conductors are arranged in different layers, as a result of which braided multiphase double layers are produced. The length of a conductor strand formed by the series connection of the moulded conductors is independent of the slot depth, and all the phase strands in a braided double layer are structurally identical. Enlarged connecting points which are all accessible on the end surfaces of the winding overhangs all the time are achieved in that moulded conductors which are joined together in pairs before installation have asymmetrical ends. Motors and generators which are equipped with moulded conductors according to the invention are distinguished by high efficiencies and power densities.
Patent DE-4405278-C1 (DE)
Title: Process and apparatus for polishing or matting glass surfaces in an acid bath
Inventor: KAPPLER GERHARD
IPC: C03C15/02
Filed: 1994-02-19
Granted: 1995-05-04
Abstract: A process for polishing or matting glass surfaces in an acid bath (polishing bath) using hydrofluoric acid as active component uses a comparison pattern whose properties correspond to the glass in the polishing bath. The comparison pattern here is a glass plate on which the hydrofluoric acid currently acting in the polishing bath acts for a predetermined time, after which the material-removal action of the hydrofluoric acid is measured by determining the thickness of the glass plate at the beginning and end of the period of exposure. The material-removal action determined in this way for the comparison pattern is consequently representative of the material-removal action of the polishing bath on the glass surfaces to be polished or matted in the polishing bath. With the aid of the material-removing action measured in this way, the acid concentration in the polishing bath can be regulated in order to ensure the desired action of the polishing bath. A simple way of measuring thickness comprises radiometric measurement, in which, for example, a  gamma -radiation source shines through the glass plate serving as comparison pattern and the change in thickness of the glass plate owing to the material-removal action of the acid is determined from the change in count rate at the beginning and end of the exposure period. This process and the suitable apparatus for this purpose enable automatic determination and regulation of the acid concentration with the aid of a simple thickness measurement without radioactive waste and the associated disposal problems.

Title: Adjustment of distribution of brake force between tractor and trailer
Inventor: MAYR-FROEHLICH MATHIAS
IPC: B60T8/00
Filed: 1994-04-11
Granted: 1995-08-10
Abstract: The process involves measurements of road speed (v) and braking pressure (p) by components of an antilock braking system (2), and of engine output torque (Md) by a dynamometer (9) in an electronic diesel engine control system (1) at three successive times.

Title: Glass fiber cutting technique produces fibers short to very long or m ix of them and involves open and closed production systems
Inventor: NEUT JOHANNES JACOBUS VAN DER
IPC: B05B7/14
Filed: 2007-01-23
Granted: 2008-02-26
Abstract: The glass fiber cutting technique produces fibers short to very long or a mix of them and involves open and closed production systems. In general, the required fiber material, e.g. glass fiber mats, or preformed fiber packets, all alike (known as preforms) conform to the product to be produced, so that the production process is well reproducible. With local alteration of the length of the cutting surface of the involved blades, the fiber bundle at the location of a non-present cutting surface (3) is not cut. By relative displacement of the cutting surfaces or their alteration, fibers are cut of different lengths (12). The fiber bundle is fed through a guide opening so that they clamp between a pressure roller (5) and a cutting roller (4). A drive roller (2) activates the cutting roller (4) and the fiber bundle (11) is fed between the pressure and cutting rollers to the cutting point of the blades (3). Through the pressure of the blades on the rubber-type surface, the fiber bundle is cut.
