Title: Environment-endangering waste destruction - uses incinerator burning fuel-containing waste using flue gas-preheated air for temp. boosts
Inventor: WILCK KLAUS
IPC: F23G7/00
Filed: 1979-12-29
Abstract: The installation contains a rotary furnace in which limestone, dolomite cement flour or similar material are being heat treated. The furnace is connected to an incinerator by the cooling system of the rotary furnace. The material to be treated is introduced into the installation through the upper part of the rotary furnace. Due to the rotation the material wanders towards the combustion zone of the furnace from where it is conveyed to the cooler assembly. The clinker is cooled by air and the heated air is used for boosting the firing system of the incinerator. The incinerator is fired with solid, paste, or fluid waste material while slag-producing materials, such as oil laden soil are added. The combustion air consists partly of primary air and to the greater part of air heated up in the process of cooling the clinker contained in cooler. The residue from the incinerator is removed and granulated in water.

Title: Vertical deformation measurement on flat rotating information carriers - uses measurement and processing of laser light reflection angles
Inventor: AHRENS HARALD DR RER NAT
IPC: G11B7/095
Filed: 1980-01-25
Abstract: The contactless arrangement uses an optical transducer and pick-up measures vertical deformations in flat rotating information carriers with recording tracks. The deformations are measured, evaluated and displayed in a suitable form to enable exact quantification. The light (G) from the source is deflected by a semi-reflecting mirror (Sp) in the direction of the vertical axis (Y) to the surface of the information carrier (I). Light reflected from the carrier surface passes through the semi-reflective mirror to the optical receiver (N). The receiver outputs signals on two pairs of contacts (A1,A2; A3,A4) corresp. to reflection angles in the horizontal axis directions (X,Z). These signals are connected via dividers (Div1,Div2) with a central receiver connection (M) as reference to evaluation and display devices (AD1,AD2). A laser light source and a position diode receiver are used.
Patent DE-3004889-A1 (DE)
Inventor: MAESTRANI BRENNO
IPC: F16K24/04
Filed: 1980-02-09
Abstract: This device comprises a venting conduit (1) situated close to the waste pipe (19) and joined thereto, a valve (17) which controls the ingress of air for re-establishing pressures between the external atmosphere and the waste conduit (19), a relief valve for excess pressure (22) and a pipe (20) for discharging condensate. The plug of the valve (17) opens, as a result of a fall in pressure in the waste pipe (19) caused by the discharge itself, to induce an ingress of air in order to re-establish the pressure equilibrium between the waste pipe (19) and the external atmosphere, and closes when the pressures have been re-established. It prevents the escape of harmful and malodorous gases which are generated in the vent fittings, but without obstructing the air ingress necessary for re-establishing the external pressure so that the discharge pipe can function correctly. This offers an obvious advantage, in terms of both efficiency and cost, compared with the manhole-mounted conduits or pipes of the prior art. It can be used in particular in plumbing systems, septic tanks, sewerage systems and waste pipes for liquid materials or sewage in general. <IMAGE>

Patent DE-3024716-A1 (DE)
Inventor: SCHWEFEL ERNST DIPL PHYS
IPC: G01D3/02
Filed: 1980-06-30
Abstract: An improved method of interval interpolation, i.e., subdivision of a signal period, is disclosed. Generally, at least one scanning signal (S1, S2) generated by a scanning unit (G) scanning a scale (M) is converted into digital form and input to a computer (R) for the computation of interpolation values. In the case of a high subdivision factor, before the execution of the interpolation algorithm, the scanning signals input to the computer (R) are corrected for amplitude inequality, incorrect phase differential and the direct voltage component of the scanning signals (S1, S2). The correction values are automatically determined by direct voltage detectors (GT1, GT2), amplitude detectors (AT1, AT2) and a phase comparator (PV) during at least one pass of the measuring system (G, M) over its measuring interval. The correction values are stored in the computer (R) and are automatically utilized thereby in interpolation during measurement.

Patent DE-3119068-A1 (DE)
Title: Turbine rotor (wheel) and its method
Inventor: KELLER JOHANNES
IPC: F01D1/02
Filed: 1981-05-11
Abstract: A method proposed as a converter of the energy of flowing particles of a medium is to use tangential jets to direct the medium, led from a compressor into pressure-equalising chambers and converted into flow (stream) energy, onto the turbine rim rotor and guide it into the turbine rotor so as to produce pressure channels and reaction channels. A pressure channel (half wave) curved forwards in elongated fashion from the circumference merges into a smaller diameter than that with which the flow guide (stator) blade ends. This blade is consequently superimposed with respect to the circumference, the start of a further curved channel, with the result that continuous channels are produced. The external channel wall, curved with respect to the circumference, produces a (triangular) flow entrance chamber relative to the blade with a superimposed channel inlet. The flow simultaneously enters the pressure channel and, moving backwards through the guide blade, the reaction channel. The channels are divergent. This process can be performed by guiding the outlet over a plurality of stages. A windward forward channel arranged in the rotor rim, which acts also on a reverse surface leading to the reaction nozzle channel. Both methods can be accommodated in a rotor circular surface. Flow-guiding surfaces can be provided in an integrated fashion instead of jet (thrust) nozzles.

Title: Flexible shaft coupling
Inventor: FICKELSCHER KURT G
IPC: F16D3/12
Filed: 1981-06-10
Abstract: In a flexible shaft coupling, two opposite coupling halves (12, 14) are provided, each of which has flat oblique surfaces (16, 18, 20, 24, 26, 28) aligned transversely to the direction of power transmission. The oblique surfaces (16 and 24, 18 and 26, 20 and 28) of each coupling half (12, 14) face one another and each delimit an interspace (34) which widens radially in a wedge shape. Arranged in each interspace (34) is a sliding body (42, 44, 46) which has flat sliding surfaces (52, 54, 56, 58, 60, 62) which rest flat against the oblique surfaces (16, 24, 18, 26, 20, 28). The sliding bodies (42, 44, 46) are surrounded by an elastic and resiliently deformable retaining ring (98) which presses the sliding bodies (42, 44, 46) into the interspaces (34) in such a way that associated surfaces remain permanently in surface contact with one another. When subjected to a torque, the coupling halves (12, 14) rotate relative to one another, the interspaces (34) narrow and push the sliding bodies (42, 44, 46) outwards against the resilient resistance of the retaining ring (98), which, due to its elasticity, deforms eccentrically. Because the opening angle between the oblique surfaces (16, 24, 18, 26, 20, 28) changes during the narrowing of the interspaces (34), these oblique surfaces and/or, if required, the sliding surfaces (52, 54, 56, 58, 60, 62) are arranged on hemispherical compensating bodies (74, 76, 78, 82, 84, 86) which are mounted with the ability to pivot in all directions in bearing sockets (96) in the coupling halves (12, 14) and/or, if required, in the sliding bodies (42, 44, 46). <IMAGE>

Title: Plug-in coupling, in particular for hydraulic high-pressure lines and extreme-pressure lines
Inventor: WEIRICH WALTER
IPC: F16L37/14
Filed: 1981-07-04
Abstract: The invention relates to a plug-in coupling for hydraulic high-pressure lines and extreme-pressure lines, comprising a plug-in stud, with O-ring seal, and a plug-in sleeve which is provided with transverse bores for a U-shaped plug-in fork, the fork legs of which, in the coupling state, engage through an annular groove of the plug-in stud in the manner of a chord of a circle. In order to avoid excessive surface pressures and damaging deformations of the coupling parts under high loads, the external diameter (D) of the bearing shoulders (17) of the annular groove (16) is at least approximately equal to the external width (B) of the plugged-in fork (12). At the same time, the arrangement is such that the intended axes of the transverse bores (20) of the plug-in sleeve (11) pass through the annular groove (16) approximately at half the depth (T) thereof. As a result, the plug-in fork legs (12', 12'') bear on the bearing shoulders (17) of the annular groove (16) over a large surface area (bearing surfaces F). <IMAGE>
