Title: Effluent treatment - after removal of coarse solids - for separate treatment
IPC: C02F1/02
Filed: 1970-05-21
Abstract: A purification process for effluents contg. pathogenic agents by treating with chemical disinfectant such as active Cl2, consists of removing from the effluent only a small proportion of the total solids by means of fixed or moving sieves, treating the remaining effluent with disinfectant in excess quantity in an agitating vessel for a short period and, separately from this, treating the sieved solids with disinfectant in excess quantity for a longer period in another agitating vessel. By this method the coarser solids, which require longest treatment, are reduced to a small volume, so that the large volume of remaining effluent requires only shorter treatment.

Patent DE-2114706-A1 (DE)
Title: Combined ceramic compacting and glaze application - - using carrier mounted glaze
IPC: C04B41/81
Filed: 1971-03-22
Abstract: The glaze is applied to the top of a ceramic moulding in its compacting operation by the pressing onto it with the compacting punch a combustible evaporable etc., carried layer of paper, plastic metal etc., which is coated with a layer of glaze facing the compact. On subsequent firing the substrate disappears and the glaze is burnt into the ceramic onto which it has been applied. The method lends itself to mass production on rotary table type presses where a turntable type glaze covered sheet device is used. The method combines two operations into one.

Title: Coupling lines for pusher tug - has pivoted, telescopic arms to secure coupling despite varying heights
Inventor: JANSEN WILHELM
IPC: B63B21/56

Title: Glass ceramic cooking surface - has two layers of different heat radiation permeability
Inventor: SCHEIDLER HERWIG DIPL ING
IPC: H05B3/74
Filed: 1974-08-01
Abstract: The cooking surface has two layers, each with different heat radiation permeabilities for the wave range (0.7-.0.5) cm. The base layer consists of a glass ceramic of high permeability. the second upper layer, on the cooking side, has a low permeability, and a thickness of at most (1/10) of the thickness of the base layer. Both layers form a tightly-connected unit. The second layer consists of enamel, or diffused oxides. The cooking surface may consist of three layers of different heat radiation permeability. The two thin top surface layers subject each cooking plate to tension on all sides, thereby increasing its durability. These surfaces are produced by ionic exchange after crystallization.

Title: Four stroke engine with ignition and strata charge - cylinders have two separate mixture intakes and common combustion chambers
Inventor: LANGE KARL-HEINZ DIPL ING DR
IPC: F02M35/108
Filed: 1974-08-02
Abstract: Each cylinder is provided with two separate air fuel mixture induction pipes (3, 4) controlled by separate inlet valves (7, 8) actuated by cams having approximately the same contours. The one induction pipe (3) feeds a comparatively rich mixture from a carburettor to the inlet valves (7) close to the spark plug electrodes (14). The second induction pipes feeds a comparatively weak air fuel mixture to the second inlet valve (8) from a second carburettor which produces a greater air mixture ratio at part load and a less air mixture ratio at full load than the usual accepted ratio. The resulting toxic exhaust emmission content is reduced thereby to an acceptable level.

The feeder pipes can point down or upwards passing through the floor (1) via floor adaptor flanged pipe which is adjustable to suit any floor thickness. These adaptors give the feeder pipes a strong support and pleasing appearance. Between two sections of feeder tubes there is a shock absorber to guard against knocks and at the end interchangeable supply elements are fitted (i.e. sockets, switches, communication connections etc.). The feeder pipes are made of coloured bakelite covered aluminium or of rigid plastics.
Patent DE-2447554-A1 (DE)
Title: Tube straightening machine with deforming rolls - imposes additional elliptical deformation on tube for increasing rate of straightening
Inventor: KUTZENBERGER KARL-HEINZ DR
IPC: B21D3/05
Filed: 1974-10-02
Abstract: A tube straightening machine subjects a tube in the straightening process continuously to an alternating bending moment. The straightening process, however, does not depend entirely on bending. The plasticity of the material is reached quickly by imposing additionally a double elliptical deformation on tube cross sections. The straightening machine has three bending rollers, and another set of rollers which act also as reaction rollers to them. The major axis of the elliptical cross section is imposed so that it follows a helical path along the tube length.

Patent DE-2452418-A1 (DE)
Title: Afterburner for gases exhausted from processing plants - having compactly arranged double heat recuperation equipment
Inventor: ZENKER KURT DR ING
IPC: F23G5/46
Filed: 1974-11-05
Abstract: In an arrangement comprising a processing plant and an afterburner which destroys contaminants in the air exhausted from the processing plant, all of the heat required for the process and for the afterburner is introduced through the afterburner only. The hot gases leaving the afterburner give up part of their heat content in a heat exchanger which preheats the air exhausted from the process plant. A further portion of the heat in the cleaned gases is returned to the process plant recirculating air flow, either through a heat exchanger or by direct mixing of the hot gas from the afterburner with the process plant air stream. Used in drying, curing, baking and other ovens, distillation equipment, printing machines etc., to destroy solid particles or gaseous contaminants in the exhausted gases. The energy requirement for the plant is reduced by heat recovery; and the insulation requirements of the afterburner chamber are reduced by passing process plant recirculating air over its outer surface.
