Patent DE-2600089-A1 (DE)
Title: Yarn dyeing process - has path deflectors for yarn leaving dye followed by false twisting in a counter airstream
Inventor: BOUS KARL
IPC: D02J1/02
Filed: 1976-01-02
Abstract: A process and apparatus are claimed for dyeing, and other fluid treatments, of yarns and textile yarn material where the yarn is drawn from a bobbin at high speed to pass through the dyestuff. After leaving the dyestuff, the yarn is passed several times through deflections to follow a serpentine path. The yarn then follows a straight path and, at the end, is twisted in a false twisting effect at the same time as a stream of air is directed against the direction of yarn travel. The design gives a small processing unit which allows the yarn to be passed through at high speeds, with all the process stages provided, but which occupies little space.
Patent DE-2602555-A1 (DE)
Title: Razor blade consisting of amorphous alloy - of iron, nickel, chromium, molybdenum, tungsten and metalloids with fluorocarbon polymer coating
Inventor: PELECKIS ANTHONY JOHN
IPC: C22C45/02
Filed: 1976-01-23
Abstract: Cutting instrument, esp. (safety) razor blade, has strip(s) of amorphous alloy (I) of 60-70 (wt)% Fe-4-10% Ni, 10-20 % Cr, Mo and/or W and 5-15% metalloid(s), pref. P,B,C, Al,S,Si,Ga,Ge,As,Se and/or Te. The cutting edge(s) have a (firmly) adhering coating of a solid fluorocarbon polymer (II), pref. PTFE. MFR. is simple and the quality is better, since embrittlement of NiFe alloys on sintering the (II) coating is avoided. The (II) coating is pref. heated to a temp. of min 330 degrees C to a value above its m.pt. In an example blades produced from an alloy of 68% Fe, 4% Ni,4% Cr,2% Co, 12% Mo and 10% metalloids, with coatings of fluorocarbon telomer and PTFE, were heated rapidly, kept 8-30 min at 345-357 degrees C and chilled. Embrittlement occurred after 30 min at 371 degrees C or over but not at 343 degrees C.
Patent DE-2608913-A1 (DE)
Title: Memory unit made from electroferrite ceramic - has etched electrodes to induce remanent magnetism in gaps with low voltage excitation
Inventor: GEISEN KARL ING GRAD
IPC: G11C11/22
Filed: 1976-03-04
Abstract: A ferrite memory is designed to require low write in voltage and to be of small size. The base disc of the memory (1) is produced from a ferro-electrical ceramic material. The memory electrodes (2, 3) are produced as thin layers of conducting material by an etching process. The memory action is generated by remnant magnetism across the gap (4) between the write-in electrodes (3) and a central annular electrode (2). The small gap between the electrodes minimises the write in voltage necessary for entering data. Read out is provided by excitation voltage applied to central electrodes (6) located on the top and bottom surfaces of the plate.

Title: Repetition transport system with lifting magnet - has initial excess current subsequently reduced to transport desired quantity only
Inventor: OERTEL KLAUS DIPL ING
IPC: B66C1/08
Filed: 1976-03-15
Abstract: The system is for the repetition transport of a set number of workpieces of magnetisable material at a time from a bulk store to a discharge point, using a lifting magnet. At the loading point, the magnet is energised by a heavier current than is necessary to lift the set quantity, thus picking up an excess amount, which it then lifts to a setting position above the loading point. The energising current is then reduced to a value corresponding to the set quantity and the excess items drop free until the desired number only remain. The current is then increased again and the magnet with its calibrated load transported to the discharge point, where the current is switched off to dump it.

Title: Ships tank vent pipe head - has full bore outflow element and small dia. inflow pipes with float valves to exclude water
Inventor: LOOKS ARNOLD
IPC: B63J2/10
Filed: 1976-04-10
Abstract: The ship's tank vent pipe head has a annular portion (2) of the same bore as the vent pipe, welded co-axially to its top and a hinged (6) lid (1). A U-shaped stirrup (7) is mounted removably to straddle the lid and prevent it opening so far that it would not drop shut again. One or more pipes (8) of much smaller bore than the vent pipe are led through the sidewall of the head to form goosenecks. Their vertical outside ends carry buoyant-ball type non-return valves (9, 10, 11). Gas or air flow outwards, liable to be rapid and large in quantity, is through the full bore opening. Some can also be through the gooseneck pipes, which along suffice for the much smaller quantity of air flowing inwards.
Patent DE-2618257-A1 (DE)
Title: Folding and notching of large sheets for filling - has folds made to reduce to standard size and cutouts to prevent prong interference
Inventor: BAY OTTO
IPC: B42F13/00
Filed: 1976-04-27
Abstract: The method of applying perforations applies to the strip shaped binding edge of a folding sheet having a larger sheet format than the binder. The sheet size is shortened for binding purposes by one or more folds running transverse to the length direction of the binding edge resulting in a final size corresponding to the edge length of the binder. Apart from the hole perforation on the binding edge to assist in the binding process a cut out is made at each point of the folded section, spanning the area of the holes of the perforations to prevent interference between the filing prongs and the underlying, imperforated sheet edge. A reinforcement layer is applied at least to the area of the intended holes before the perforation process.

The printed side of the carrier layer may be coated with a dried aq. dispersion of vinylidene chloride copolymer. The strip attracts the attention of a dredger driver by its resistance to tearing.
Patent DE-2628218-A1 (DE)
Title: Guidance control for tracked bus - uses limited steering on rear axle to track within front wheel curve defined using guide rollers
Inventor: FOERSTER HANS-JOACHIM PROF DR
IPC: B61F9/00
Filed: 1976-06-23
Abstract: The tracked bus operates as a normal bus in suburban streets and as a tracked vehicle inside the city. Lateral guide rollers (6, 9) monitor the edges of the track and steer the front wheels accordingly. Semi automatic, or fully automatic travel is then possible, with precise timetabling and high density. To prevent the rear wheels from dragging in the curves, reducing efficiency, the rear axles is unlatched to allow a limited angular swing, with lateral guide rollers (10) to provide the correct tracking control. About 7 deg. in each direction is sufficient to enable correct tracking to be achieved. For normal travel the rear axle is locked rigid.

Title: Dyeing and printing fibrous material contg. reactive hydrogen atoms - with azo dyes produced on the fibre
Inventor: ELTZ HANS-ULRICH VON DER DIPL
IPC: D06P3/68
Filed: 1977-03-19
Abstract: In the parent patent, fibrous material contg. reactive H atoms is dyed or printed with azo dyes produced on the fibre, by treating the material with an aq. bath or printing paste contg. a coupling component, the soln. of a diazotisable primary aromatic or heterocyclic water-soluble fibre-reactive amine, alkali and NaNO2, followed by acidification.

Title: Constant infusion rate from two bottles - by suspension on balance beam to keep same liquid level
Inventor: BETZLER HERMANN
IPC: A61M5/14
Filed: 1977-03-25
Abstract: A device for use in the infusion therapy where two fluids have to be infused in a vein at a constant rate ratio uses a balance beam on which the two bottles for the infusion media are suspended. The lever arms, centres of gravity, and masses are so calculated that at the desired ratio of the flow rates, the liq. levels in both bottles always remain in the same horizontal plane. This holds the hydrostatic pressure in both lines constant so that the set drip rate is automatically maintained and the expensive two precision pumps are not needed.

Title: Schaltung mit einer vielzahl nebeneinander angeordneter stromgeneratoren
Inventor: STORCH KLAUS DIPL ING
IPC: H03M1/66
Filed: 1978-06-01
Abstract: 8 Diese Schaltung ist vorzugsweise für Digital-Analog-Wandler bestimmt, wo es darauf ankommt, daß jeder Stromgenerator einen genau gleichen Strom liefert. Im Gegensatz zum Stand der Technik, wo entweder jeder Stromgenerator für sich geregelt oder die Regelgröße des einen als Steuergröße für alle übrigen dient, erfolgt hier eine Regelung derart, daß streng symmetrische Differenzverstärker die Stromdifferenzen benachbarter Stromgeneratoren herabregeln und daß der letzte halbe Differenzverstärker mit dem ersten halben verbunden ist, so daß eine angleichende Beeinflussung aller Stromgeneratoren untereinander erfolgt. Es fließen nur sehr geringe Ströme durch die Differenzverstärker, so daß die damit kleinen Offsetspannungen über die Regelungen in die Genauigkeit der Stromdifferenzen transformiert werden.
