Title: Parquet tile, process for the production thereof and means for carrying out the process
Inventor: KISSELOFF PANTELEY DR ING
IPC: B27M3/06
Filed: 1984-04-16
Abstract: The parquet tiles are laid next to one another to form the parquet flooring. The parquet tile comprises a multiplicity of individual lamellae (3, 4). In order to hold these lamellae (3, 4) together for the purpose of handling the parquet tile, wires (5) are used which are clamped in indentations (6) of the lamellae (3, 4). The parquet tile has lamellae (3, 4), arranged at right angles with respect to one another, in order to form a mosaic flooring. The clamping wires (5) and indentations (6) of a parquet tile are parallel to one another and extend over the length of the parquet tile. This results in cost-effective manufacture since a long sheet can be continuously manufactured and individual parquet tiles can be cut therefrom. Small joints are to be present between the lamellae of the finished parquet tile so that it can be somewhat flexible, for easier laying, and so that its lamellae can expand to a certain extent with changing humidity. In order to form the joints between those lamellae (4) which are parallel to the clamping wires (5), the latter are provided with bent-off portions (7). <IMAGE>

Patent DE-3507242-A1 (DE)
Title: Drive system for flat cards or willows
Inventor: STEINBACH CHRISTIAN
IPC: D01G15/36
Filed: 1985-03-01
Abstract: The invention relates to the drive system and the rotational-speed control of the feed roller, the licker-in/drum drive, the doffer and the flat chain. The aim of providing a simple electronic control of the rotational-speed ratios, whilst ensuring a high sliver quality of the flat card or willow, is based on the object of allowing the continuous rotational-speed setting of the drive motors of the feed roller, doffer and flat chain and the changes in rotational speed of the licker-in/drum drive and doffer drive with constant acceleration or deceleration. According to the invention, a frequency converter is arranged respectively in the current leads of the drive motor of the feed roller, of the drive motor of the doffer and of the drive motor of the flat chain. The current leads of the drive motor of the licker-in/drum drive and of the drive motor of the doffer are guided by way of a change-over unit. By means of the change-over unit, a starting or a braking control circuit with invertor can be cut into the current leads of the drive motor of the licker-in/drum drive or of the drive motor of the doffer at the location of its frequency converter and, after the running-up or braking operation, can be cut out or changed over to other flat cards.

Patent DE-3513987-A1 (DE)
Inventor: KALKHOF BERND DIPL ING
IPC: H01L29/74
Filed: 1985-04-18
Abstract: A monolithic, integrated lateral thyristor whose parasitic barrier layer capacity (Dp) and whose parasitic substrate transistor (Tp) are compensated for by simple structural measures. In the transistor's emitter regions (T1) n<+> doping is applied, so that an inverse transistor (T3) is produced, which draws off the minority carrier current from the parasitic transistor (Tp). The capacity diode (Cd) is rendered ineffective by a bleeder resistor (R). Through these measures it is possible, even when there is a rapid increase of voltage on the anode (A), to prevent unintentional igniting of the thyristor.

Patent DE-3524713-A1 (DE)
Inventor: AUER WERNER
IPC: H01H51/14
Filed: 1985-07-11
Abstract: A movement system, in particular for adjusting the rotor of a wave-guide switch in two switching positions. The rotor comprises, for example , a single-pole permanent magnet pair (24). On the stator side, two drive coils (28, 29) are fixed to a coil support (30). By energizing one of these coils (28, 29) the rotor is brought close to one switching position. The switching positions are defined by the mechanical stops (32, 33) on the stator side and by the neck (25) on the rotor side. By means for example of an appropriate permanent magnet part (34, 35), the forces of attraction come into play at the switching positions between the rotor and these parts, which move the rotor into the switching positions. In order to damp the transition behaviour of the rotor into the selected position an eddy current damping system (26, 27) is provided, with braking coils (short-circuit windings) which are in addition fixed to the coils on the stator and come into action in the vicinity of the switching positions.

Title: Apparatus for feeding dust-like material into a pneumatic conveying system
IPC: B65G53/46
Filed: 1985-08-07
Abstract: The apparatus for feeding dust-like material into a pneumatic conveying system comprises a charging chamber 16, in which there are arranged an inlet valve 5 and an outlet valve 3. The said valves are pretensioned in the closed position by a common spring. These valves are optionally opened hydraulically by exerting a load on the pneumatic pistons 2 and 4 which are connected to them and on which the closing spring 12 is also supported. When one valve is opened as a result of loading the corresponding pneumatic piston with compressed air, the spring is compressed further, increasing the closing force on the other valve. As the entire system is pneumatically operated, leaks are of no importance as the leaked air and dust do not escape to the outside, but into the system itself. <IMAGE>

Title: Sliding device, especially alpine ski
Inventor: KUCHLER WALTER
IPC: A63C5/00
Filed: 1985-09-17
Abstract: The sliding device is a further development of the patented sliding device (Patent Application P 3505255.4). An upper and a lower ski body enclose an intermediate space and are connected to one another in a torsion-proof manner in the main loading region, i.e. in the region immediately in front of and behind the binding, in the alpine ski. The ski bodies thereby form a "torsion box" which can absorb the load in a resilient manner. This results in the ability to move in a skate-like manner, making the sliding device very easy to turn and giving it good adhesion and a good tracking ability.

Title: Method and apparatus for comminuting solids
Inventor: KLOECKER MAX DR
IPC: B02C15/00
Filed: 1986-01-31
Abstract: In known bowl mill crushers, only the grinding bowl is driven, the grinding rollers being carried along by the grinding bowl due to the frictional engagement with the latter. This necessitates a drive motor which is designed with particularly large dimensions and a very high power and has a special, very complex and expensive gearing. Also, such large-dimension drive units are not only difficult to fit and remove, but the mill has to be stopped during repairs to the motor and/or to the gearing. Also, in these known bowl mill crushers, the grinding effect is not optimal due to the relatively poor drawing-in of the solids between the grinding bowl and the grinding rollers. All of these disadvantages are, however, eliminated according to the invention by the grinding bowl (10) and at least one of the grinding rollers (11, 12) being driven independently of one another. <IMAGE>
