Patent DE-3123033-A1 (DE)
Title: Keyboard
Inventor: MIYANO RYUZO
IPC: H01H13/02
Filed: 1981-06-10
Abstract: Keyboard or control panel having a printed-circuit board, a transparent board and keys, consisting of a key housing, a key head and a contact element made of conductive rubber. An opaque frame grid, with openings corresponding to the viewing windows for the individual keys, is printed onto the transparent board. The remaining frame parts contain openings for holding the switch housings. The switch housings are designed on the underside with legs which project into holes in the printed-circuit board so that, on the one hand, the openings in the printed-circuit board lie precisely under the windows in the opaque impression on the transparent board and a sheet placed under the complete arrangement, made visible with the symbols allocated to the keys, is visible through them, and, on the other hand, the contact electrode sets printed on the printed-circuit board lie precisely under the contact elements of the key units, so that the contact element is in each case pressed down onto the associated electrode set of the printed-circuit board by pressing the associated key head, and this key switch can thus be closed. The legs on the key housings are compressed from below onto the printed-circuit board, so that the complete arrangement is assembled firmly to form an integral arrangement. An easy assembly capability is thus provided, even for large-area keyboards, as well as a representation of the key symbols which is separated from the key operation, without the transparency of the viewing windows suffering as a result of the repeated key operation, the symbols becoming illegible or transparent window caps suffering damage even during production which adversely affects the transparency. <IMAGE>

Patent DE-3215921-A1 (DE)
Title: Roller conveyor
Inventor: KRUSE WERNER DIPL ING
IPC: B65G47/26
Filed: 1982-04-29
Abstract: The roller conveyor contains a plurality of drivable rollers (6, 6', 6") which are supported in a frame (1, 2). Each roller has its own drive in the form of an electric motor (7, 8) which is preferably a short-circuit-resistant asynchronous motor and especially a so-called "rotating field magnet". As a result of the slip between the rotating field of the stator (8) and the rotor (7), each roller may individually have its own speed as a function of the speed at which it is forced to rotate, which may also be zero. The roller conveyor thus acts as a friction roller track. <IMAGE>

Title: Apparatus for converting carbon and/or sulphur in an organic or inorganic sample into a gaseous carbon or sulphur compound
Inventor: GRAF WOLFGANG DR
IPC: G01N31/12
Filed: 1983-02-25
Abstract: Apparatus for rapidly preparing CO2 and SO2 from substances containing organic/inorganic carbon or sulphur in order to determine the stable isotope ratio. An apparatus known in elemental analysis was modified in such a way that it can be used for fairly large sample quantities and consequently for preparing the test gases. The oxidation chamber and reduction chamber were separated by a flow resistance and a gas inlet or gas outlet was fitted between these two zones. The substantially larger oxidation chamber can be completely filled with oxygen before combustion without the contact reduction catalyst being oxidised by flushing the oxidation zone with O2 and simultaneously flushing the reduction zone with helium, the two flushing gases escaping via the additional gas outlet. Furthermore, the contact reduction catalyst can be activated by the additional gas feed resulting from introducing hydrogen. The reaction products are collected in a cold trap which simultaneously serves as a sample loop for the gas chromatographs used to separate the gases.
