Patent DE-2631622-A1 (DE)
Title: Continuous, simultaneous feeding of powder and liq. - into inlets to processing machines, e.g. mills, extruders, etc.
Inventor: DUERR HERBERT DIPL ING
IPC: B29C48/03
Filed: 1976-07-14
Abstract: In a process for continuously and simultaneously feeding powdered solids and liqs. into a processing machine, the liq. is formed into a hollow cylindrical jacket, into whose centre the solid material is introduced. The liq. is introduced through a ring manifold having a continuous, vertically downwards orientated slot, or a series of small, outwardly inclined holes, the jets from which combine to form a continuous curtain of liq. on the inner surface of the machine inlet. The powder flows downwardly from an inlet pipe enclosed by the liq. ring manifold. Process is used for feeding e.g. mixers, paddle mills, screw extruders, etc. Agglomeration and encrustation in the machine inlet are prevented.

Title: Foundry moulds and dies - contg. elements which heat the empty die and them provide cooling for directional solidification of a casting
Inventor: KAHN FRIEDHELM PROF DR ING
IPC: B22D27/04
Filed: 1976-10-13
Abstract: The rate of heat extn. from foundry moulds or dies is controlled during casting, where the mould contains combined heating and cooling elements (a) which are first used to heat the empty mould to the required working temp. After pouring, elements (a) are used in a desired time sequence to control the rate and direction of heat extn. so the feeder head is the last part of the melt to solidify. During this sequence, each element (a) is cooled to a temp. where solidification is completed in the vicinity of that element. Cooland is pref. sprayed periodically in small amts. and in a desired sequence into a row of elements (a); and the moulds are pref. made of segments with different thermal conductivity (TC), esp. using dies into which elements (a) are cast and are in direct contact with the molten metal. Elements (a) maybe partly surrounded by thermal insulation and contain a coolant feed pipe with low TC. The invention combines chill casting with directional solidification to obtain a fine-grained casting free from piping, segregation, cracks and stresses.

Title: Viewing appts. for electric arc heating process - has electromagnet to divert arc during observation of work zone
Inventor: LUEBBERT ULRICH DIPL ING
IPC: B23K9/08
Filed: 1976-11-13
Abstract: Inspection appts. for mfg. processes employing electric arcs has an electromagnet to divert the arc during the period of examination so that the excessive light output from the arc does not interfere with the photographic or TV camera employed. An arc (3) is struck between an electrode (1) and the workpiece (2). The objective (14) of a TV camera (15) is focussed on the heated zone which is observed through a viewing aperture (11) and an aperture disc (13). A control circuit (17) which drives a motor (16) is coupled to the aperture disc switches on an electromagnet (18) to divert the arc whilst observations of the work zone take place.

Title: Sewage clarification using active carbon regenerated in situ - with active carbon forming anode of electrolytic cell
Inventor: HALMOE TERJE MARTIN DIPL ING
IPC: C01B31/08
Filed: 1976-11-17
Abstract: A method of clarifying waste waters, esp. from sanatoria, and industrial effluents, uses active carbon which is oxidised during the process. Oxidn. is effected by nascent O2 generated by laying an electrical current on to the active carbon, as against the cathode, so as to bring about an electro-chemical reaction in the effluent. Organic matter absorbed by the active carbon is oxidised with the carbon acting as a catalyst, whilst the H2 produced at the cathode is wasted. Method can be used generally for the clarification of effluents. The plant works efficiently and keeps the cost of regenerating the active carbon to a min.

IPC: G07F7/08
Filed: 1976-12-30
Abstract: The card comprises two interconnected plastic layers (1'a, 1'b) which enclose a series of flat, reflecting interface areas (R, R1, R2...). The interface areas are combined in groups to form reflex zones (RZ), the individual zones being separated by non-reflecting or only diffusely reflecting separating zones (TZ). The angular position of the interface areas in relation to the card plane and the position of the interface areas in the card plane represent the information stored on the card. The angular positions of the interface areas are discrete and are read out by means of photoreceivers (P1-P4) aligned according to the discrete angular positions (@1-@4). <IMAGE>

Title: Safe spacing indicator for vehicle - has stop watch to measure time interval between vehicles with coloured scale divided into distinct regions
Inventor: LEYK KLAUS
IPC: G04F7/06
Filed: 1977-01-07
Abstract: The safe distance between vehicles is measured as being equal to half the speed so that the time interval between the vehicles is a fixed value. A simple measuring device monitors the time interval between the two vehicles passing the same point on the road and displays the value on a coloured scale divided into safe and dangerous settings. The indication can be either a simple stopwatch movement or an electronic display such as an LED. The safe time interval is about 1.8 secs so that the spacing is automatically increased or increasing speed.

Title: Solar collector incorporating heat exchanger and transparent cover - made by encasing components in foam plastic in mould
Inventor: JUNG ANTON L DIPL ING
IPC: F24J2/04
Filed: 1977-01-13
Abstract: The solar collector consists of a heat exchanger, covered by a transparent material. Such exchangers are made of metal or plastic materials conditioned to have a strong absorption in the infra-red or visible regions of the spectrum. For this, varnish or soot may be applied as a layer, or a material can be mixed in. The transparent layer should prevent cooling of the collector by convection. It consists of a plate of glass or plastic material with a high transmission coefft. for wave-lengths 3 mu m and strong reflection for wave-lengths >3 mu m. The transparent material, the heat exchanger and distance pieces are inserted in a compact body formed of plastic foam. The collector is made by placing the transparent material, the exchanger, the distance pieces and a frame in a mould, closing the mould and filling it with foam. Cf. existing collectors, the collector is very efficient, is light and can be made easily and at low costs.

Title: Inspecting rolled prods. for surface defects - where prods. are coated with indicator soln. and subjected to high frequency induction heating which reveals the defects
Inventor: GAVRILIN EVGENY FEDOROVITSCH
IPC: G01N21/91
Filed: 1978-04-25
Abstract: The surface of the rolled prod. is coated with a substance (A) forming a background for a second substance (B) which changes colour when heated. High frequency heating is then used so that defects on or near the surface of the prod. cause a thermochemical change in substance (B) altering its colour so the defects are clearly visible. When substance (B) is used as a soln., drying is pref. used for coating (B) at a temp. below that causing its colour to change. Substances (A,B) may alternatively be combined in an aq. colloidal suspension, contg. 30-160 g/l KOH in soln. and 5-20 g/l soluble potato starch. Used for inspection of ingots and slabs which still have a scaled surface due to hot rolling, or for examining profiles, e.g. rails or girders. The invention can be used without prior surface treatment of the rolled prods.
