Title: Plasticising and injection moulding unit has hydraulic thrust drive - optionally with proportional or servo control system with components common to both
Inventor: HEHL KARL
IPC: B29C45/50
Filed: 1980-04-05
Abstract: Unit comprises a piston-cylinder unit (I) sliding on guide bars for the axial injection stroke a screw is pushed by its support bridge which also constitutes the cylinder of the unit. The piston has a hollow piston-rod passing through the cylinder head and attached to the support bridge for the injection barrel whereas the guide bar passes through the hollow piston rod and the rear end cylinder head. The control of the fluid pressure and flow in the piston cylinder unit (I) is provided optionally in one of two ways (according to the purchaser's wishes): either by proportional valves or by a servo valve; with proportional valve control the piston is actively loaded on one side in the chamber towards the piston-rod end. With servo control the piston is of a different form, is double- acting (loaded both sides) and passes through the rear end of the cylinder with a piston dia. exceeding that of the hollow rod. For exacting requirements the servo control can be used; while for less exacting requirements proportional (preset) control is adequate. At the same time, only one basic model is required.

Title: Current and voltage controller - has series voltage controller cascaded with parallel voltage controller to give constant output voltage
Inventor: DETHOLOFF ROLF
IPC: G05F1/618
Filed: 1980-05-13
Abstract: The controller produces a constant output voltage from a constant input current where the input and output voltages are almost identical. A series and a parallel voltage controller are connected one after the other. The parallel controller produces a constant output voltage defined by a voltage divider Current and by the slightly higher constant voltage from the series controller. It is intended for telephone systems current supplies and implemented using integrated precision regulates. A resistor lies between the series controller output and the parallel controller input. This resistor along with the constant output voltages from the controllers ensures a constant input current that is larger than the max. load current taken from the parallel controller.
Patent DE-3020111-A1 (DE)
Title: Series connected circuit breaker discrimination - prevents complete tripping of all series connected switches on supply side of switch closest to fault
Inventor: HILD KARL-HEINZ
IPC: H02H7/30
Filed: 1980-05-27
Abstract: For a fault (K2) at the load (L1), the nearest switch (S3) contacts part in response to the instantaneous overcurrent release. After a set time a blocking signal is sent to the series connected switches (S2,S1) to prevent the main trips from operating. The closest switch (S3) continues its fault clearing action and the main trip operates. When the contacts are fully open the blocking signal is cancelled. There is a brief time delay between the onset of blocking and the main trip operation to prevent complete opening due to transient faults. The contacts of the series connected switches begin to open due to the high speed release action. The main trip action is however blocked, and on cancellation of the block, and clearing of the fault current by the close up switch (S3), their contacts again close.

Title: Nitroso di:phenyl amine prodn. by nitrosation in aq. alcohol - to give high yield and purity, useful as vulcanisation retarder
Inventor: GROTKOPP DETLEF DIPL CHEM DR
Filed: 1980-08-06
Abstract: Prodn. of N-nitroso-diphenylamine (I) from diphenylamine (II) is carried out by reacting (II) with a mixt. of water and a lower alcohol (III), followed by nitrosation in conventional manner at 5-54 (15-30) deg.C. (III) is pref. EtOH, n-PrOH and/or i-PrOH, esp. i-PrOH. The water/(III) wt. ratio is 1:99 to 70:30 (4:96 to 65:35), esp. 60:40 for n- and/or i-PrOH and 30:70 for EtOH. In an example 1080 g coarsely ground (II) were added to a soln. of 1296 ml water and 864 ml i-PrOH at room temp., then 360 g conc. H2SO4 were added and the mixt. was cooled to 20 deg.C. 1780 ml 25 wt.% NaNO3 were added dropwise, the temp. being allowed to rise to 30 deg.C. Cooling was no longer necessary and addn. of nitrite was complete after 3 h. After stirring for 1 h longer, the mixt. was filtered and the (I) obtd. was washed and dried in vacuo at 40 deg.C. The (I) yield was 1256 g, corresp. to 99.3% of the theory; purity 99.97%; m.pt. 66.4-67 deg.C. An almost quantitative yield of highly pure (I), practically free from organic and inorganic impurities, esp. the toxic 4-amino-diphenyl, is obtd. (III) can be recovered from the aq. phase with little loss by azeotropic distn., without costly fractionation. (I) is useful as a vulcanisation retarder.
