Title: Dishwasher waste water treatment - has a buffer to flock contained matter for sepd. by a sieve or filter
Inventor: BACHON ULRICH DIPL ING
IPC: C02F1/24
Filed: 1991-09-19
Abstract: The kitchen waste from a dish washer and the like, passes out as ground material with water which is flocked. The flocked matter is separated from the water by a sieve or filter. Pref. a flocking agent at the flocking stage, with a neutralising agent and a selected auxiliary flocking agent according to the need to float or precipitate the flocking. Floating matter is supported by flotation, and the sieve or filter action for the floating and precipitated sludge is without pressure, and both sludges can be filtered or sieved together. The waste water to be flocked is collected in a buffer stage. The emulsion is cracked by cracking chemicals at the buffer stage. The flocking and auxiliary flocking agents are of vegetable origin. Edible calcium is used as the flocking agent. Air is excluded at the sedimentation and the sieve/filter stages. The waste water from a dish washer is treated in a separate flocking and separation stage, in a buffer container. A further chemical treatment is applied after flocking sludge separation, and the separated sludge is sieved/filtered together with the sludge from the first flocking stage. ADVANTAGE - The system recovers matter from the waste water which does not load the sewage disposal, and gives matter which can be recovered such as for fodder.

Patent DE-4134089-A1 (DE)
Inventor: IMHOF ERICH
IPC: F16L21/08
Filed: 1991-10-15
Abstract: The shear-protected plug-in collar connection is intended for mouldings and for socketed pipes (1) which are produced using the centrifugal casting process and in the case of which the tip end (3) of the one pipe can be pushed into the collar end (2) of the other pipe with radial play. Arranged in the collar end are a sealing ring (8) and a clamping ring (14) which is constructed separately therefrom and has a large number of clamping segments (15) which are arranged with a mutual separation in the circumferential direction and have an outer jacket surface (17) of spherical construction and, on their inner surface (18), in each case one tooth system (19) which, when axial forces occur as a result of the interaction of the spherical jacket surface (17) with an inner surface (18) of the pipe collar (which tapers conically to the end), press radially against the tip end (3). An elastomeric retaining part (20), which can be fixed on the collar end and supports it, is integrally formed on the clamping ring (14). A design which ensures correct retention is achieved even in the case of relatively large nominal widths if the annular-disc-shaped section (23) of the retaining part, which comes to rest on the collar end surface (22), comprises in the region of the inner edge of the collar end surface (22) a transition region (26) which is of reinforced construction and has a higher bending strength, and from which the connecting section (24) which leads to the clamping ring (15) originates, and if the collar end surface (22) has, on the inner-edge side, a recess region which is matched to the cross-section of the transition region (26) which is of reinforced construction. In this case, a steel ring (28) which increases the bending strength and can possibly be inserted through an axial insertion gap (29) is allocated to the transition region (26) of the retaining part, which region is of reinforced construction.

Title: Method and device for measuring the air mass of a flowing pulsating medium
Inventor: WILDGEN ANDREAS DR ING
IPC: G01P13/04
Filed: 1993-02-24
Abstract: For the exact determination of the air mass sucked into the induction tract of an internal combustion engine, excluding a reverse flow falsifying the measured value, at least one of a multiplicity of resistor tracks arranged on a substrate transversely to the flow direction is led to an additional contact location. By means of quotient formation from the voltages which can be picked off at the contact locations, it is established whether the quotient deviates from a predetermined value upwards or downwards, from which the flow direction can be established. In the determination of the measured value, only the desired flow direction is taken into account. Applicable to air mass meters in internal combustion engines. <IMAGE>
