Patent DE-2610761-A1 (DE)
Title: Error simulation circuit in multi module electronic units - employs manual or automatic intermediate logic circuit and programmable microprocessor
Inventor: NEUDATSCHIN NIKOLAUS DIPL ING
IPC: G06F11/26
Filed: 1976-03-15
Abstract: The circuit arrangement comprises a logic circuit (LS) situated between the first and second modules (M1, M2). In normal operation the output of the first module would be conveyed direct to the second modules. The logic circuit is under the control of a separate unit (SE). The control unit is visualised as a microprocessor under either manual or automatic control and is intended to transmit either a binary 'O' or '1' signal between the modules, for teaching or demonstration purposes. The logic circuit (LS) typically contains two AND gates, and OR gate and an inverter, all on one chip. This enables the module output signal (Y) to be related to the input signal (S) by the Boolean algebraic equation Y=E (SN+N ), where N and E are the control input and output signals.

Title: Electrolytic redn. of naphthyl ethers in alcohol soln. - uses solid electrodes, giving enol ethers useful as pharmaceutical intermediates
Inventor: SKALETZ DETLEF HERBERT DR
IPC: C25B3/25
Filed: 1976-04-27
Abstract: Process for dihydrogenating naphthyl ethers (I), having >=1 ether gp., comprises electrolysis under galvanostatic conditions of a soln. of (I) in a 1-3C alcohol solvent, contg. is not >5 vol. % water and opt. a small amt. of a cosolvent. A through-flow cell is used with separate cathode and anode compartments and an R4N+ or R4P+ salt or hydroxide (R is CH3 or C2H5) is added as supporting electrolyte. A solid cathode of a material with H2-overvoltage more negative than that of Cu and a conventional solid anode are used. The temp. is -20 to 120 degrees C and the pH >8. The prods. include enol ethers which can be hydrolysed to beta-tetralones which are starting materials for analgetics and for morphine- or steroid-like cpds. The process is applicable to 1-alkoxy and esp. 2-alkoxynaphthalenes and is economic. In an example, 2-methoxynaphthalene was electrolysed in methanol to a mixt. contg. 56.2% 3,4-dihydro- and 25% 1,2-dihydro-2-methoxynaphthalene.

Title: Cubicle for outdoor switchgear - has shock absorbing plate to prevent material escape following switch explosion
Inventor: HACKENBERG PETER DR ING
IPC: H02B13/025
Filed: 1976-06-05
Abstract: The kiosk (1) comprises a box structure ventilated at the top. One side at least is provided with an access door. The roof has openings to permit the escape of hot gases following a severe trip or explosion in the circuit breaker (S).

Patent DE-2633084-A1 (DE)
Title: Dustbin lifter for collector vehicle - has adaptor with two parallel rods mounting stop plates which retain bin upper flange
IPC: B65F3/04
Filed: 1976-07-22
Abstract: A refuse collector truck has a bin lifting adaptor which can handle two sizes of bins of quadratic cross section. The adaptor has two parallel rods which provide pivot locations for two stop plates. The stop plates retain the top flange on the bin when it is lifted and tilted for emptying. When the smaller size bin is attached to the adaptor, a spring loaded pressure plate moves the pivot rods axially inside guide sleeves. This causes the pivot pins to rotate about 90 deg. so that the flanges on the stop plates reduce the adapter to its minimum width.

Title: Removable operating catch for vehicle roof - has keyway to block removal until roof is in secure position
Inventor: STAIGER HELMUT
IPC: E05B63/12
Filed: 1976-12-29
Abstract: The vehicle roof panel is swung open after securing catches are released with a removable handle (13). The handle fits into the catch via a special keyway which prevents the handle from being removed with the catch in an intermediate position. The edge of the catch has a flange which fits over the profiled key of the handle. The handle can only be removed with the catch in either of its end positions. This ensures that the panel is secured in the open or fully closed setting, and that it does not suddenly fly open after being closed.

Title: Regenerator for pseudo-ternary digital signals - multiplies regenerated carrier with frequency equal to multiple of half bit frequency by received equalised sideband
Inventor: DOEMER JOSEF ING GRAD
IPC: H03M5/16
Filed: 1977-09-30
Abstract: The regenerator, for carrier frequency pseudo-ternary coded digital signals, is simplified by omitting the phase selection circuit normal in such regenerators and is made independent of the coding employed. A carrier wave is derived from the received signal and has a frequency equal to a multiple of half the digital signal's bit repetition frequency at the transmitter. This carrier is then multiplied with the receive, equalised sideband to regenerate the original digital signal.

Title: Controlling melt-viscosity for extrusion foam coating of HF cables - by metering crosslinking agent to plastics foam matrix to give less than thirty per:cent degree of crosslinking
Inventor: STENZEL HANS-DIETER DR ING
IPC: B29C48/295
Filed: 1977-11-11
Abstract: Parent patent describes the mfr. of an envelope of plastics foam for elongated articles by plasticising a plastics in an extruder; introducing a gas into the plasticised melt to thoroughly distribute it in the melt; applying the gas-enriched melt onto the elongated article; and initiating a chemical cross-linking of the plastics immediately before it issues from the extruder. In the addn. the amt. of cross-linking agent added to the plastics is metered so that it suffices for a max. degree of crosslinking of 30%. Used e.g. for plastics-insulating coaxial H.F. cables. It has been found that less than 30% crosslinking is sufficient to achieve an adequate rise of melt viscosity for further processing.
