Patent DE-4203968-A1 (DE)
Title: Checking data line in multiplex system using loop connection - generating control signal from transmitted loop signal and returning loop signal as stop bit of data channel
Inventor: SCHWEIGER LUDWIG DIPL ING
IPC: H04M3/22
Filed: 1992-02-11
Abstract: A loop signal (SS) is transmitted from a transmitter (MXS1) of a first multiplexer (A) to the receiver (MXE2) of a second multiplexer (B). The received signal (SS) is analysed and a first control signal (SS1) is generated. This prompts the transmitter (MXS2) of the second multiplexer (B) to transmit the same loop signal (SS) which is analysed and signalised in the receiver (MXE1) of the first multiplexer (A). The loop formation in the first multiplexer (A) is stopped by a second control signal (SS2) generated by a received loop signal (SS) until the loop command is cancelled and the second control signal (SS2) has disappeared. ADVANTAGE - When computer infrastructure or computer fails data line can be checked easily via loop connection without requiring extra transmission capacity.

Abstract: The invention concerns a bolt lock, in particular one for control-cabinet doors or similar doors or flaps, the lock comprising a flat-bar bolt which is mounted to move parallel to the edge of the door, preferably within the arc of swing of the door, and which has at least one locking section. The lock further comprises a bolt holder, mounted on the doorframe and designed to receive and hold the locking section of the bolt. Also included is a bolt actuator designed to move the bolt longitudinally between an open position and a locked position. The aim of the invention is to provide a more secure lock which cannot become stuck. To this end, the invention calls for the flat-bar bolt (10) to be twisted about its longitudinal axis over at least one part (11) of its length in order to form the locking section, the bolt being twisted in such a way that the bolt surface in the twisted section (11) is at an angle to the orientation of the bolt (10) and so that a lug (16) in the bolt holder (14) extends out over the locking section at the same angle to the bolt (10), thus acting as a locking surface (13).

Patent DE-4239328-A1 (DE)
Inventor: MERKENSCHLAGER HANS-HERMANN DI
IPC: H05K3/42
Filed: 1992-11-23
Abstract: The invention relates to a method for producing printed circuit boards with through-plated holes and very small solder lands, or no solder lands, in accordance with the Tenting method. In the case of the Tenting method there is a risk of the photographic film (5) tearing off and etching medium penetrating into the through-plated holes (3) and damaging the copper layer (2) located on the hole walls. In order to avoid this disadvantage, the invention provides that the printed circuit board is provided with an etching-resistant protective film (4) before being coated with photographic film (5). Once the conductor pattern has been developed, the etching-resistant protective film (4) is removed from the free copper surface (2) by briefly treating in acid, and the conductor pattern structure is then produced using alkaline etching medium. Once the photographic film (5) has been stripped off, the protective film (4) is removed from the walls of the through-plated holes (3) by means of acid. <IMAGE>
