Patent DE-3735172-A1 (DE)
Title: A digital spirit level with integrated distance meter with fully electronic measuring mechanism and LCD display for craftsmen and DIY enthusiasts
IPC: G01C9/06
Filed: 1987-10-14
Abstract: The advantages of the digital spirit level consist in particular in that craftsmen and hobbyists have available an exceptional precision as well as measurement accuracy. Thus, one person can measure and survey a room entirely by himself in order, for example, to make rough calculations for material needs or can exactly measure gradients of the most varied levels to one-tenth of a degree. The measurement accuracy exceeds by a long way all previous tools such as "spirit levels" and "foot-rules", especially that of measuring tapes, if these sag. The housing and the technology inside the digital spirit level are shock-proof and almost indestructibly mounted. The balance pendulum is mounted in special oil and damped against shocks but can be readjusted at any time, particularly after inexpertly rough handling, if the viewing lens shows a red signal and requests calibration. The digital spirit level can be produced in any length and with different operating possibilities, in order to be right for the most different users.
Patent DE-3744456-A1 (DE)
Title: Cardboard cutter
Inventor: REHM HELMUT
IPC: B26B5/00
Filed: 1987-12-29
Abstract: In known cardboard cutters, the knife blade is fastened to a slide which is mounted in the handle casing in a longitudinally displaceable manner. To prevent accidents, a restoring spring is provided which automatically retracts the slide into its protected position in the casing. This has the disadvantage of making it necessary for the slide to be manually advanced and held for cutting, which quickly leads to tiredness. In order to achieve automatic advancing of the knife blade (16) at the start of the cutting process, a friction disc (22) is provided which is rotatably mounted in the casing (10) and projects from it. On the friction disc (22) there engages a carrying element, for example a transmission wire (28) which, in the event of rotation of the friction disc (22), advances the slide (12) with the knife blade (16) against the force of the restoring element (18) into the cutting position. <IMAGE>

Patent DE-3809265-A1 (DE)
Title: Gas generator for steam/coal gasification
Inventor: HOHN HANS DIPL ING
IPC: C10J3/56
Filed: 1988-03-19
Abstract: The heating of a gas generator for steam/coal gasification is effected via heat exchanger bundles which are arranged in a pyrolysis zone 3 and a gasification zone 4. The heat exchanger bundles consist of pipe coil packs (14, 19) which are in turn formed from a multiplicity of pipe helices (15). From a number of pipe helices (15) in each case, large cylindrical cages of different diameter are assembled which are arranged coaxially in one another. This results in uniform internals which not only have a light weight and can easily be dismounted and reassembled, but also in low pressure drops in the pipe helices (15). The latter do not have to rely on a narrow bending radius, so that, in particular, simple repeated checks by means of a probe which can be passed through the pipe helices (15) are also possible. <IMAGE>

Patent DE-3813276-A1 (DE)
Title: Circuit arrangement for transferring CVBS signals from at least two different picture signal sources selectively or jointly to a single picture signal sink
Inventor: RAUBUCH MARTIN DIPL ING
IPC: H04N9/896
Filed: 1988-04-20
Abstract: For the joint reproduction of two picture signals on one common screen (picture-in-picture), the two picture signals must be synchronised to one another in their synchronisation frame. If the time base of one picture signal still fluctuates, as is the case in a replay from tape, additional problems occur in the synchronisation. According to the invention, the timing error of the unstable picture signal is corrected which is also of advantage when it is replayed by itself. For this timing error correction, a commercially available field buffer, for example two chips of the SN4700 type is provided into which the unstable picture signal is written with the synchronisation frame of a stable time base, with interposition of a buffer memory, and is read out again. This stable time base can be generated either by a free-running crystal-controlled time base circuit (without "picture-in-picture" representation) or, in the case of a "picture-in-picture" representation, achieved by synchronising the then no longer free-running time base circuit with the synchronisation frame of the other time-stable picture signal. Both picture signals are split into their Y, U and V component signals and multiplexed in this component form (after stabilisation of one picture signal) for the "picture-in-picture" representation. The buffer memory compensates for the asynchronism between the unstable time base of the picture signal to be corrected and the stable time base of the free-running ... Original abstract incomplete.

Abstract: A display arrangement for parallelepipedal bodies (7) (containers with picture and sound carriers) possesses a plurality of insertion holders (6), having first pivoting-bearing parts (9). By means of these, the bodies are mounted in a row one behind the other between two mutually parallel profiled bodies (1), each having one row of second pivoting-bearing parts (5). The first and the second pivoting-bearing parts (9 and 5, respectively) form mutually complementary pivoting-bearing arrangements, by means of which the insertion holders (6) can be turned over between two sloping positions. To provide a conversion possibility and a limited pivoting about a defined axis (AS), the first (9) and the second pivoting-bearing parts (5) have mutually coaxial outer and inner partial-cylinder faces (10 and 14, respectively), from each of which lead two flank faces (11 and 15, respectively) which lie on both sides of the pivoting axis. In this arrangement, the flank faces (15) leading from the outer partial-cylinder face (14) and the flank faces (11) leading from the inner partial-cylinder face (10) touch one another in pairs at each end of the pivoting region on one side of the pivoting axis. On the respectively opposite side, however, they are at an angular distance from one another, defined by the pivoting region. <IMAGE>
