Patent DE-3438446-A1 (DE)
Title: A process for producing ceramic powders and a device therefor
Inventor: OZAKI YOSHIHARU
IPC: C01F7/30
Filed: 1984-10-19
Abstract: The production of ceramic powder is carried out by atomising and hydrolysing metallic or non-metallic oxides-, hydroxides- or hydrate-forming compounds in the presence of water and by calcination of the metallic or non-metallic oxides, hydroxides or hydrates of the said compounds, which are formed in an atomised state by the above hydrolysis. The ceramic powder is produced in a device having an atomisation/hydrolysis device, in which compounds giving metallic or non-metallic oxides, hydroxides or hydrates are atomised and hydrolysed in the presence of water and in which the metallic or non-metallic oxides, hydroxides or hydrates of the compounds, formed by the said hydrolysis, are calcined as such in the atomised state. The atomised substances are completely hydrolysed, before they are thermally decomposed inside a furnace, and immediately calcined in order to obtain ceramic powder as the end product.

Title: Method of disposing of waste, in particular domestic refuse
Inventor: GRISAR ALEXANDER DIPL ING
IPC: F23G5/02
Filed: 1986-02-22
Abstract: In a method of disposing of waste, in particular domestic refuse, in which the waste is separated into at least two fractions and a fraction thus produced with a high calorific value is incinerated, it is proposed to separate the waste in such a manner that the fraction with a high calorific value assumes a gross calorific value between 2400 and 4300 kcal/kg, in particular between 2600 and 3100 kcal/kg, and this fraction is incinerated at at least 1100 DEG C, preferably at at least 1200 DEG C. As a result the refuse quantity to be incinerated is maximised and an environment-considerate waste incineration of high energy efficiency is achieved. The waste incineration is preferably carried out in free flight or in a rotary furnace.

Title: Machine for producing vibratory concrete pipes
Inventor: RAUSCH ERNST OTTO ING GRAD
IPC: B28B21/76
Filed: 1986-06-21
Abstract: The invention relates to a machine for producing vibratory concrete pipes, with a cylindrical mould through which a core can be advanced and with a lower sleeve sealing at the bottom the annular chamber, to be filled with concrete, between the outer circumferential surface of the core and inner circumferential surface of the mould, and an upper sleeve, sealing at the top, which can be placed on after the concrete is filled in by means of an advance device. The invention is based on the object of improving a machine of the generic type described at the outset such that concrete pipes can be produced with precise pipe length and very small longitudinal tolerances. This object has been achieved according to the invention in that the advance device has an actuable advance-path delimiter and in that the advance-path delimiter has a release means which can be set to predetermined path lengths.
Patent DE-3626039-A1 (DE)
Title: NOx reduction by ammonia in a fluidised-bed furnace
Inventor: HOELTER HEINZ DIPL ING
IPC: F23C9/00
Filed: 1986-08-01
Abstract: It is known in the case of fluidised-bed furnaces to add ammonia to the combustion air, more precisely either in the air distribution box or in the combustion air feed line before its junction with the air distribution box, that is prior to entry into the fluidised-bed furnace. The added ammonia passes with the combustion air through the temperature zone in the fluidised-bed furnace and the majority is burnt here. It follows from this that a very high superstoichiometric amount of ammonia must be employed in order to achieve a sufficiently high reduction of NOx. In order to avoid this disadvantage, according to the invention it is proposed that the ammonia is introduced above the fluidised bed into the boiler together with fresh air and/or recycled flue gas. The flue gas recycling is less than 10% of the total amount of flue gas. The fresh air feed above the fluidised bed is several times that of the ammonia dosage. A fan (8) controls the fresh air feed and a further fan (9) the flue gas recycling. Both lead together into an air-ammonia mixing tube (7). Inside the boiler, a plurality of nozzles are arranged above the fluidised bed (2) as outlet orifices. <IMAGE>

Patent DE-3702176-A1 (DE)
Title: Torsional vibration damper
Inventor: WOLF FRANZ-JOSEF
IPC: F16F15/14
Filed: 1987-01-26
Abstract: Torsional vibration damper consisting of three concentric ring elements, namely a hub ring, a flywheel ring and a spring ring, in which the flywheel ring is provided radially to the inside of the hub ring and of the spring ring, which is arranged between the hub ring and the flywheel ring. The operating frequency of the torsional vibration damper is thereby made speed-dependent, in particular in such a way that the effective operating frequency of the torsional vibration damper is shifted increasingly towards higher values as the speed increases by increased stiffness of the spring coupling between the flywheel ring and the hub ring owing to the action of the centrifugal force.
Patent DE-3704175-A1 (DE)
Title: Process for producing a non-perishable animal feed from silage material
Inventor: LUETH BERND
IPC: A23K30/15
Filed: 1987-02-11
Abstract: Silage material, which has very good keeping quality in the absence of air, spoils on contact with atmospheric oxygen, since aerobic bacteria decompose the silage material. The object is thus to make the silage material keep longer by means of a process. The object is achieved according to the invention in that sorbic acid as a preservative in a suitable concentration is intimately mixed with the silage material in the feeding of herbivorous and omnivorous mammals, in particular horses, cattle and pigs. The use of the preserved silage material is particularly well suited to users who only feed small amounts of silage.

IPC: B23Q3/157
Filed: 1987-08-18
Abstract: In a magazine for placing tools in readiness for NC machine tools to be tooled by hand, it is proposed, in order to avoid errors upon removing the tools (4) or putting them back, to cover on the magazine the receiving slots (3) for the tools (4) with a bell-shaped enclosure (5) and to guide the tool (4) to the removal opening (6) by means of a control piece (7), which is movably guided between two stops (8, 9) and has a carrier (11), and a locking bar (12) and to lock the magazine (1) by means of slots (13). Upon re-inserting the tool (4), by means of a stop (14) the locking bar (12) is unlatched and the control piece (7) is guided with its stop surface (17) in front of the removal opening (6) and thus prevents immediate re-removal of the tool (4). <IMAGE>

Filed: 1988-01-27
Abstract: The invention proposes a connecting device for the releasable coupling of construction parts, in particular laminated components, e.g. walls, panels, claddings, etc. to posts, crossmembers, frames or the like. The connecting device is composed of a retaining cam 5 which can be fixed in a rotationally fixed manner on a construction part, and of a connecting pin 6 which can be inserted rotatably into the other construction part, the connecting pin 6 exhibiting a supporting head or collar 12 which is provided with a tool-engagement means, e.g. a transverse slot, and is adjoined by a shaft 13 which is provided, at or near its free end, with radial anchorage protrusions 14, whereas the retaining cam 5 contains an engagement through-passage with a profile which is adapted to the shaft cross-section and the anchorage protrusions 14 and at whose rear end there are located, as abutments for the anchorage protrusions 14, anchorage shoulders which are offset laterally at an angle. By virtue of the fact that the retaining cam 5 contains, at its front end, run-in ramps 24 which extend in a steeply helical manner and, at its rear end, bracing ramps 25 which extend in a steeply helical manner, it is possible for the connecting pin 6 to be aligned automatically and satisfactorily with the engagement through-passage of the appertaining retaining cam 5. <IMAGE>
