Title: Making surface defects visible on steel billets or slabs - by impingement with high press water at rel high temp to cause descaling
Inventor: GLOMB KLAUS DIPL ING
IPC: B21B45/00
Filed: 1972-09-20
Abstract: The surface defects in steel blanks such as billets or slabs etc. are made visible by descaling the surface, specifically carrying this out at a temp. below that at which the mterial is worked in subsequent shaping operations, and using high press. water for the descaling operation. Pref. the operation is carried out at 1,100-500 degrees C and the material is subsequently slowly cooled down. The method overcomes the shortcomings of the two conventional methods of descaling in which using metal granules which are impinged on the surface fine cracks tend to be closed up, or in the alternative method of etching the defects are very difficult to see due to the effects of the acid on the surface.
Patent DE-2259075-A1 (DE)

Size of unit is suitable for tapered sprue walls to be drilled out in old tools to convert them to accept this new hot runner module, and eliminate sprus removal operations. Springs can be readily exchanged to suit various melt pressure conditions.

Title: Highly pure organic pigments prepn - by forming suitable dyestuff salts (sulphates), recovering pure dyestuff and comminuting it
Inventor: SPIETSCHKA ERNST DIPL CHEM DR
IPC: C09B67/14
Filed: 1973-12-06
Abstract: Highly pure organic pigments are prepd. by treating organic dyestuffs having differing degrees of purity with suitable acids, which dissolve impurities in the dyestuffs, to form the corresp. dyestuff salts (pref. sulphates) which can be isolated; these salts are sepd. from the acids, and are treated with water so as to recover the dyestuff in pure form, and the dyestuff is then finely divided mechanically in aq., organic or aq. -organic medium. Organic dyestuffs such as highly halogenated (chlorinated) copper phthalocyanines, and dyes of the quinacridone, perylene tetra carboxylic acid, polycyclic quinone, dioxazine, indigo and thio indigo series and also acid-stable azo dyes, may be purified, but the process is esp. suitable for highly halogenated copper phthalocyanines. The procedure obviates the filtration of large volumes of greatly diluted acid (H2SO4) pigment suspension, and the working up of large volumes of dilute acid contg. impurities. The pigment are used for paper, plastics, resins, lacquers, textiles, paints, etc.

Title: Torque overload safety drive for machine tool - has spring-loaded idler gear actuating motor limit switch
Inventor: SCHELL FRIEDRICH
IPC: F16H23/10
Filed: 1974-03-02
Abstract: The drive from the motor shaft is transmitted through an idler gear to the machine tool shaft. The idler pinion runs on a spindle mounted transversely in the shaft, in which a slot large enough to clear the pinion diameter is cut at right angles to the spindle axis. The shoulders abut against washers which in turn press against compression springs. Under overload conditions the spring force is overcome by the tangential load on the idler pinion so that the shaft is lifted against the spring force, and the adjusting screw knob operates a lever of the limit switch. When operating in the reverse direction the lower limit switch is actuated.

Title: Microcard reader with self aligning cassette - has locating tags for holes in micro card and hinged upper and lower panels
Inventor: RINN JUERGEN DIPL ING
IPC: G03B21/11
Filed: 1974-03-23
Abstract: The microcard reader has a special cassette for accurate alignment of the microcard.

Title: Continuous microwave furnace - has extremely high electrical attenuation before open entry and exit
Inventor: FRITZ KARL DR
IPC: H05B6/78
Filed: 1974-06-15
Abstract: The continuously operating oven has six or more tunable trap groups with characteristic impedance approx. equal to that of the heating chamber. They are arranged mirror symmetrically in pairs opposite each other at a distance of half the wavelength along the tunnel. The wavelength, in comparison with the heating chamber cross-section, is so long, that only waveforms H11 and H10 can be generated. In order to reduce field amplitude before the traps, the energy is fed at several points along the chamber, with chamber parts electrically separate from each other by the trap assembly or, in order to correct the polarisation direction, by screens or noncritical waveguides.

Title: Nuclear power station district heating - utilises waste heat from oil hydrogen and water coolers
Inventor: KOREK JOHANNES DIPL ING
IPC: F01K27/02
Filed: 1974-09-19
Abstract: A steam turbine drives a generator with its stator water cooled and the rotor hydrogen cooled. The water and the hydrogen are circulated through coolers, as the turbine lubricating oil in all of which heat is removed by exchange with water. This water is taken from the return of a district heating system and is circulated by a pump through the coolers and into the district heating flow pipe. The flow then continues through a steam heated after heater into the distribution system serving several users for space heating. A small but useful proportion of the power station input energy is regained without any reduction in the electrical output.

Title: Lifting electromagnet with pole face winding - has winding arranged in spiral form to give alternate pole polarity between grooves
Inventor: SARAFANNIKOW ANATOLIJ A
IPC: H01F7/20
Filed: 1974-09-19
Abstract: The windings are embedded in spiral slots in the active pole material to give two branches. Each is a spiral lying within the other, and they are joined at the centre. Current passing from terminal to terminal thus flows in towards the centre and then out again thereby magnetising the pole material to give a successive sequence of alternate poles across the magnet face. The winding may be excited with either direct or alternating current. By employing three branches suitably displaced a three phase excitation may be used. The magnetic field is of approximately equal strength over the whole face of the lifting face.

One coating is connected electrically to the housing and the other coating to a connection body which protrudes through a cover body made of insulating material inserted at the open end of the pot-shaped housing. A sealing ring made of elastic material is inserted between the cover body and the bent over front edge of the pot-shaped housing. Thermoplastic material is particularly suitable for the manufacture of the cover body (6) and ensures a close connection to the cable (9) if the cable sheath (8) is made of polyvinyl chloride.
