Patent DE-3141340-A1 (DE)
Title: Arrangement for stabilising the rotation speed of externally-controlled converter motors
Inventor: LOESEKANN WOLFGANG DIPL ING
IPC: H02P25/024
Filed: 1981-10-17
Abstract: The application relates to an arrangement for rotation speed stabilisation of externally-controlled converter synchronous motors, especially in cases when these motors are connected to "soft" networks or imbalances are possible in the tacho-machine or disturbances on the measuring line. In order to prevent these sources of error, according to the invention a deviation in rotation speed, which is determined by a nominal-actual value comparison, is passed directly to the triggering unit of the network converter, and the nominal value is passed to the triggering unit of the machine converter. This allows the voltage in the DC intermediate circuit to be influenced. <IMAGE>
Patent DE-3143810-A1 (DE)
Title: X-Ray intensifier film
Inventor: DEGENHARDT HEINZ DR RER NAT
IPC: G03C5/17
Filed: 1981-11-04
Abstract: The invention relates to X-ray intensifier films, in which especially known rare earth phosphors are used as intensifying agents, i.e. for converting the X-rays into visible light which readily blackens exposure materials such as photographic film. In these intensifier films, a reduction of the image graininess has proved to be desirable, during which the intensifying action is not reduced. According to the invention, only a very slight loss of intensification, as compared with the known use of other pigments, for example black pigments, has to be accepted, if a pigment (5), which has the highest possible reflection in the range from 440 to 450  mu m and, below 400  mu m, an at least approximately 100% absorption of the light emanating from the phosphor layer (2), is added to the latter. X-Ray intensifier films improved according to the invention are applicable especially for exposures in medical X-ray diagnostics. <IMAGE>

Title: Built-in kitchen cabinets with an integrated household appliance, such as dishwashing machine or the like
Inventor: ROHDE REINHARD
IPC: A47B77/08
Filed: 1982-01-16
Abstract: In built-in kitchen cabinets with an integrated household appliance, a lower terminating strip marking the plinth height of the built-in cabinets is provided as a gap-free sight screen which is attached in the region of the set-back portion of the plinth and is constructed as a removable piece of the strip on the insertion opening for the household appliance. As a result, the household appliance can readily be moved for servicing purposes or the like. Due to the gap-free joining of the terminating strip to the removable piece of the strip, the observer furthermore gains the impression of a continuous, one-piece lower termination of the flaps and doors of the built-in kitchen cabinets.

Patent DE-3206556-A1 (DE)
Title: Method and roll stand for rolling out strip material of different widths
Inventor: FELDMANN HUGO DR
IPC: B21B13/14
Filed: 1982-02-24
Abstract: When rolling out strip-material cross-sections of different widths, the rolling campaign is begun with the largest cross-sectional width encountered and concluded with the smallest cross-sectional width encountered. To achieve an optimum strip profile in the direction of the cross-sectional width, the defined supporting length for the work-roll barrels is set at least approximately to the respective width of the strip-material cross-section. For this purpose, the diameter of the barrels of the work rolls is reduced by removal of material in the longitudinal regions in which they project beyond the respective cross-sectional width and, as a result, they are relieved relative to one another at the circumference of the barrel and relative to the barrel surfaces of the back-up rolls.

Title: Material feed device on presses, stamping machines or similar machines
Inventor: HARSCH ERICH
IPC: B21D43/09
Filed: 1982-07-17
Abstract: The invention relates to a material feed device on presses, stamping machines or similar machines. Different feed apparatuses have hitherto been provided when processing bands of material, strips and sheet bar i.e. when the type of material was changed, one apparatus had in each case to be removed and another apparatus attached to the press in its place. In order to reduce the expenditure required for this, the invention proposes a material feed device which is characterised by the combination of a band feed apparatus (A) with an apparatus (B) for feeding strips and blanks. The two apparatuses form a single unit which is arranged in vertically adjustable manner in front of the press (1). The particular apparatus desired can be adjusted to the working plane by corresponding adjustment.

Title: Device for generating, detecting, processing and displaying written symbols
Inventor: HAGEMEYER FRIEDRICH DR PHIL
IPC: G06V30/224
Filed: 1982-08-03
Abstract: The invention relates to a "device for generating, detecting, processing and displaying written symbols" such as letters, numbers, mathematical symbols, musical notes and other graphical symbols and is preferably constructed as a writing pen which contains a writing system which consists of a writing point with or without emission of a writing substance, a holder for the writing point and/or sensors, and which, controlled by the writing process during the hand-written writing of a symbol, generates particular physical state sequences typical of this symbol, which are converted into suitable signals in a converter and to which a particular symbol from a finite symbol set is allocated in a symbol analyzer. The symbols detected by the symbol analyzer can be processed in a process, and the symbols detected and/or processing results can be temporarily stored and displayed by means of a display and/or tone generator. The device can contain additional devices such as, for example, an electronic clock or a communication unit which, like the processor, can be controlled in their functions via the symbols written down and detected. <IMAGE>

Title: Plug-in connector for optical waveguides
Inventor: HERSE KLAUS ING GRAD
IPC: G02B6/38
Filed: 1982-09-23
Abstract: In a plug-in connector which consists of two identical connectors (1) that can be screwed to an attached protective cap (5) in each case, the plug-in openings are covered by a rotary disc when the connection is undone in order to protect against the intrusion of foreign bodies. Said rotary disc is mounted between a cover plate (24) which is rigidly connected to a plunger part. 
<??>In its position of rest, the rotary disc blocks the withdrawal of the plunger part, which is accommodated in an axially displaceable fashion in the connector housing (2), until the cover plates (24), provided with projecting attachments, of two connectors engage reciprocally in complementary recesses on the rotary disc when being joined, and cancel the blocking function thereof by mutual rotation of the connectors (1). In this process, the plug-in openings are simultaneously released. When the connector housings (2), which are provided with connecting claws, are subsequently pushed into one another, the plunger parts withdraw, and the end faces of the fibre end ferrules, which plug into receptor ferrules that are guided in through bores of the plunger parts, come to bear against one another. 
<??>The mutually engaging connectors are finally fixed by means of cap nuts (3), which are seated on their housings (2) and are screwed onto the connecting claws, which are provided with an external thread, of the respective other connector.
