Title: Device consisting of a light-conducting plate with elevations
Inventor: FANDRICH HEINZ-JUERGEN
IPC: F21V8/00
Filed: 1987-09-05
Abstract: Light-conducting plates with elevations are light-conductive plastic or glass plates, which have elevations on one of their large surfaces, from which elevations the light present in the plate emerges with a stronger intensity than in the vicinity of the elevations. A luminous element (illuminant) is to be constructed from these plates which has luminous elevations which can be variably inserted on the surface of the light-conducting plates. This is achieved by mutually connecting the elevations and light-conducting plate by means of light-conducting connectors in such a manner that the elevations have a light-receiving plug-in foot and the light-conducting plates have a light-transmitting sink.

Patent DE-3732868-A1 (DE)
Title: Thermal printing method and device
Inventor: KARAALI CIHAT DIPL ING
IPC: B41J2/38
Filed: 1987-09-25
Abstract: In a known thermal printing method, the resistance heating elements, which can be heated up cyclically to a printing temperature by being provided with main current pulses, of a thermal printing head are preheated by preheating currents to a temperature level below the printing temperature. In this process, the actual instantaneous temperature conditions at the resistance heating elements are not taken into account so that reductions in the printing quality can occur. In each actuation cycle, the preheating currents are switched off during the cooling pause following the actuation of the resistance heating elements (R1...Rn) respectively intended for printing, up to a specific time at which the cooling temperatures have dropped below the preheating temperature. The preheating currents are controlled by controllable resistance elements (T1...Tn) which are connected in series with the resistance heating elements (R1...Rn) to a voltage source (V+). The new thermal printing method and the new thermal printing device relate to the preheating of a thermal printing head. <IMAGE>

Filed: 1988-02-03
Abstract: The electrical connections and other supply leads can be connected to a terminal board (1) with built-in connection mounting parts (10) and contact pins (11) from the bottom side. On the upper side, the connection mounting parts (10) each have a plug hole (12) for the control pins (31, 32) of the switching plug (3). In addition, the connection mounting parts (10) are connected via electrical leads to contact pins (11) which likewise project from the upper side of the terminal board (1), onto which contact pins the mountings (20) of the frame element (2) can be plugged. The supply leads of the motor of a pump, for example mains connections, control leads for switch timers and the like, are attached to these mountings without conversion of the plug connections. The rotational speed of the drive motor of the pump, which motor is connected to the terminal board (1), is altered by changing the plug (3). When the drive motor of the pump is disassembled, for example for the purpose of repair work, the frame element (2) is separated together with the windings of the motor which are connected to the contact pins (11), which substantially simplifies the work and reduces the costs. <IMAGE>

Title: Memory space saving method of storing data which must be found quickly
Inventor: LAWEN PETER DIPL ING
IPC: G06F17/30
Filed: 1988-06-29
Abstract: A memory space saving method of storing data blocks which must be found quickly, and to each of which linearly pre-sorted keys are assigned, is given. The keys are arranged in the lowest node level of a t-ary B*-tree. If the maximum number of keys in a node is exceeded, it is not divided as is otherwise usual, but the greatest key is transferred to the adjacent node which contains the next greatest key. If no adjacent node exists, a new node is created. By using the method, creation of only partly occupied nodes is avoided. The B*-tree is densely stored. <IMAGE>

Title: Arrangement for inductive data transmission
Inventor: RIEM ALEXANDER DIPL ING
IPC: B61L3/12
Filed: 1988-11-14
Abstract: A data transmission path for industrial trucks (F) is designed in such a way that the cable sheathing is removed in a four-wire path-side cable (K) on the provided communications points (KE) and the conductors (H1, H2, R1, R2) are formed into short loops for inductive coupling with the antennas (A) of the trucks (F). The cable (K) is connected between the communication points (KE) in such a way that parallel-connected wires are in each case used as forward conductors (H1, H2) and two wires are used as reverse conductors (R1, R2). The planes in each case formed by the two wires are perpendicular to one another. The cable (K) between the short loops is thus unaffected by irradiated electromagnetic interference and is, however, easier to lay than, for example, a twisted pair. <IMAGE>
