Patent DE-2452425-A1 (DE)
Title: Applying a plastics, esp upholstered, covering onto a support - by HF welding foils of different colours and surface characteristics together
Inventor: BREITLING ROLF DIPL ING
IPC: B29C63/00
Filed: 1974-11-05
Abstract: Applying plastics covering(s), esp. upholstered covering, to a support, comprises HF welding together, with the use of electrodes, plastics foils which differ from one another in colour and/or surface characteristics. A foil to be applied to another one is roughly trimmed, placed onto the other foil and the excess margin is then mechanically trimmed off during the welding-together step. The "excess margin" is defined as the edge of the foil to be applied that protrudes over the electrode. No need for time-consuming positioning of an accurately dimensioned section of foil. The final trimming during the welding step is easy because the foil is then in a plastic, severable state. The resulting edge is, after cooling and solidification, clean and true to the desired contour.

Title: Digital telecommunications system prevents wrong connection - when two-wire analog cct. is coupled to four wire digital cct.
Inventor: DIETZE WOLFGANG
IPC: H04L25/00
Filed: 1975-06-18
Abstract: The digital telecommunications system is designed to prevent wrong connection by two-wire analog circuits being connected to four-wire digital circuits, and also operates correctly when the coupler passes dc signals as well as the pilot signal. The pilot signal receiver operates a switch when a pilot signal is detected. This switch a return-signalling generator to the return channel. A second switch is operated by a return-signalling receiver coupled to the forward-channel when the return-signalling signal has been detected. The second switch remains operated for as long as the first switch. The return signal has its frequency and level chosen, so that it is blocked when an analog two-wire circuit is connected to the other side the coupling matrix.

Title: Switching circuit for DC and AC - has mechanical and semiconductor switches giving both fast make and fast break actions (SW260476)
Inventor: UDVARDI-LAKOS JANOS DIPL ING
IPC: H01H9/54
Filed: 1975-07-21
Abstract: The switching circuits may be used for DC and AC currents. It consists of a series-coupled mechanical disconnector and a semiconductor switch and has both a rapid break and a rapid make action. The mechanical disconnector contacts are opened by a switch-off command that also turns off the semiconductor switch. The semiconductor switch (2) turns off automatically when the current is broken; no special circuits are needed. With the switching circuit 'open' the mechanical contacts are the first to close when a 'close' command is received. This switches the supply on quickly. The semiconductor then follows after a given delay or depending on the signal being switched.

Title: Derivation of quasi-synchronous bit cycle from binary signal - using receiver clock pulse generator disconnected when synchronisation word is recognised and reconnecting at following time
Inventor: HERZIG WOLFGANG
IPC: H04L7/04
Filed: 1976-05-14
Abstract: The circuit derives a quasi-synchronous bit cycle from a binary signal. The signal is divided in equal time intervals (frames) whose beginning is marked by a fixed bit pattern (synchronisation word). A synchronisation word followed by time marking is used at the sender side. When the synchronisation word is recognised at the receiving end a clork pulse generator is switched off. It is switched on again with a fixed specified phase at the following time mark. By using two, alternately switched pulse generator, it is possible to start at exactly defined stipulated time points at high bit pulse frequencies of fixed predetermined phase.

Title: Distributed security alarm network - detects several infringements separately and triggers appropriate timed alarm signal for each case
Inventor: HAEGELE GEB TRAEGER INGRID
IPC: G08B29/16
Filed: 1976-05-19
Abstract: The distributed security alarm network is designed partic. for burglar alarm systems, in which a security infringement produces a timed alarm signal but leaves the rest of the network operational to detect any further infringements. The alarm network (1) contains a number of parallel circuits (2) each serving a number of local detection elements (9) arranged on pair of supply lines (8). These elements (9) essentially change impedance when a disturbance occurs, and this produces an imbalance voltage in a resistance bridge (11) in the evaluation circuit concerned. Each evaluation circuit also contains an amplifier (13) and logic array containing an inhibit flip flop (19) and all these circuits supply a logic unit (4), together these release an alarm (5, 6) when appropriate, and inhibit the relevant evaluation circuit by setting its flip flp (19), but leave the remaining circuits operational. An adjustable timer (7) allows the alarm signal duration to be set.

Title: Roll crusher drive - with independent drive for each roll in the pairs of each grinding stage
Inventor: NITSCHKE GERHARD
IPC: B02C4/42
Filed: 1976-07-22
Abstract: A roll crusher plant for crushing, breaking and grinding granular material such as coffee or cereals consists of several stages, each with a pair of contrarotating rolls. Each roll in each pair is arranged so that it can be rotated independent of the other, pref. each roll of each pair having its own drive motor. Compared with conventional designs where the movable roll is driven by coupling gears from the driven roll, downtimes to remove remnants between the roll gap at every start have been saved. Drives need not be chosen larger than necessary in order to overcome blockages by remnants on starting. The action is now one of grinding and not of squashing which produces material of better quality.
