Title: Tri:chloro-silane continuous prodn. from silicon tetra:chloride - by high temp. reaction with hydrogen, then reaction with silicon at lower temp.
Inventor: GOEPPINGER ALOIS
IPC: C01B33/107
Filed: 1980-06-27
Abstract: In the continuous prodn. of SiHCl3 by reacting SiC14 with H2 and the HCl formed with crude Si, a mixt. of SiCl4 and H2 is exposed to a temp. of 900-1300 deg.C for 200-2 s in a high temp. reactor and the resultant HC1, after cooling is reacted with Si in a sec. reactor for 200-2 s at 280-350 deg.C, forming more SiHCl3. The SiHCl3 from the 2 reactions is condensed and sepd., whilst the unreacted and reformed SiCl4 and H2 are returned to the high temp. reactor. Pref. the sec. reactor is a fluidised bed reactor. The temp. in this bed is pref. adjusted to 280-350 deg.C by cooling with a tube filled with liq. SiCl4 dipping into the bed. The SiCl4 vapour formed on cooling is pref. mixed with H2 and passed to the high temp. reactor. Waste SiCl4 formed in the redn. of SiHCl3 to very pure Si is converted to SiHCl3 as economically as possible.

Title: Process for removal of a specific (predefined) component, which is present in a mixture of a plurality of fat components, from the mixture thereof
Inventor: KAWAI JUN
IPC: B01D9/04
Filed: 1981-01-07
Abstract: A mixture of a plurality of fat components is rapidly cooled using an ultra-low temperature coolant, which converts the mixture into brittle granules composed of fine particles. Each granule has a very low mutual solubility with other components. The granules are warmed to a temperature in the vicinity of the lowest freezing point among those of all the compounds in the mixture and are kept at this temperature, which principally brings about melting of the compound with the lowest freezing point, and it is removed from the multicomponent mixture.

Patent DE-3109576-A1 (DE)
Title: Angle transmitter, particularly for controlling ignition and fuel injection of internal combustion engines
Inventor: HAAS LOTHAR
IPC: F02P5/155
Filed: 1981-03-13
Abstract: This proposed angle transmitter exhibits angle marks (11), which can be scanned by an inductive sensor (12), on a rotating transmitter part (10). The opposite half waves generated by the two edges of such an angle mark (11) in the sensor (12) in each case control a transistor (17 and, respectively, 28). A microcomputer (18) detects the switching position of the transistor (17) at low revolutions and the switching position of the transistor (21) at high revolutions. To ensure a switching of the transistor (17) at very low sensor voltages, these are supplied directly to the transistor (17) whilst the higher transmitter voltages at higher revolutions are supplied to the transistor (21) via an RC section for noise voltage suppression. This makes it possible to evaluate very low sensor voltages and results in an inexpensive and rugged transmitter since only a few numbers of turns with a large wire cross section are needed. In addition, the sensor signal is automatically advanced at higher revolutions. <IMAGE>

Filed: 1981-04-29
Abstract: The mixing unit has a mixing vessel (8) and a mixer shaft (7), which is arranged therein along its longitudinal axis and at least approximately horizontally, and is mounted rotatably. Between the ends of the shaft on the one hand and its longitudinal centre on the other hand there is provided one group (A, B) each having equal numbers of ploughs (1 to 3 and 4 to 6, respectively) of which there are at least three. The ploughs (1 to 6) are each held by an arm (12, 13) projecting from the mixer shaft (7) at equal radial distances from the shaft, the effective direction of the ploughs (1 to 3 and 4 to 6, respectively) of the one group (A) being opposite to that of the other group (B). In order to achieve, at a constant mixing time and independently of the filling level, good accuracy of mixing, it is provided that the ploughs (1 to 6) are arranged about the longitudinal axis of the mixer shaft in such a way that, seen in the direction of the mixer shaft's longitudinal axis, each plough (1 to 6) is situated axially symmetrically in a circular sector whose sector angle ( alpha ) is 360 DEG  divided by the number of the ploughs (1 to 6). The ploughs then are arranged in such a way that, as the mixer shaft (7) rotates, a plane (17) containing the mixer shaft's longitudinal axis alternately has a plough of the one group (A) and then a plough of the other group (B) passing through it. <IMAGE>

Title: Method for suppressing noise echoes in radar installations and arrangement to carry out the method
Inventor: HEUN REINER DIPL ING
IPC: G01S7/292
Filed: 1981-07-09
Abstract: In a method for suppressing noise echoes in radar installations, in particular for monitoring maritime areas, it is proposed to average recursively the newly arriving amplitude values for the individual radar cells with amplitude values from previous rotations prior to the threshold value verification and furthermore to process them as target signals only if a threshold value has also been exceeded in this radar cell in at least the previous rotation. The amplitude values for the individual radar cells are stored for this purpose in a rotation memory.
Patent DE-3130577-A1 (DE)
Title: Cleaning device
Inventor: HOEFFLINGER WERNER DR
IPC: A01F12/44
Filed: 1981-08-01
Abstract: The invention relates to a cleaning device of a harvesting machine, for example of a combine harvester. Cleaning devices used hitherto, especially flat-screen cleaning devices, are subjected to uneven load, especially during harvesting on slopes, with the result that losses occur during the separation of the grains. Thus, the cleaning device has been the limiting factor in the use of axial-flow, threshing and separating units independent of slope. The object of the invention is to provide a cleaning device which is subjected to approximately uniform load and which is independent of slope. The cleaning device is therefore designed in such a way that the crop is carried over the length of the cleaning device in the vertical direction, and the crop stream is loaded transversely with cleaning air. The cleaning device has a first mechanical separation stage loaded transversely with cleaning air and formed from a screen bottom and from agitating and conveying elements arranged above the latter in the longitudinal direction. A rising separator for discharging the undesirable constituents is arranged laterally relative to the first separation stage. To increase the cleaning effect, the first cleaning stage is followed by a second cleaning stage of similar design which is likewise loaded transversely by a blower.

Filed: 1981-09-16
Abstract: In the case of a caravan, in particular a recreational trailer, with a chassis which has two longitudinal members (2) and an axle construction secured thereto, the overall height can be reduced and the centre of gravity of the vehicle can be placed lower by virtue of the fact that a flat floorboard (5), which can be walked upon, is attached by its lower side to the longitudinal members (2). A front and a rear floorboard (5, 6) can also be attached in this manner, these boards preferably being inclined towards one another in such a manner that they rise at the front and rear. The longitudinal members (2) can extend within the caravan fittings or along the caravan side walls, in the latter case projecting in the region of the wheel arches towards the centre of the vehicle. Short bearing and/or spring constructions for the wheel rockers can be connected to one another by a flat cross-tie extending parallel to the floorboard, in order also to obtain standing height between the wheel arches. <IMAGE>

Title: Oelfilmlager
Inventor: STACHULETZ MANFRED ING
IPC: B21B31/07
Filed: 1981-12-19
Abstract: Walzwerkswalzen werden mit ihren konischen Zapfen in Ölfilmlagern aufgenommen, wobei auf den Zapfen eine konische, mit der Walzwerkswalze rotierende Buchse aufgesetzt ist, die ihrerseits von einer in ein Walzen-Einbaustück eingesetzten stationären Lagerbuchse aufgenommen wird. Zwischen dem Zapfen und der rotierenden Buchse treten geringe Relativbewegungen auf. Zur Vermeidung von Haftreibung zwischen den aufeinander angepaßten konischen Flächen, die zu schweren Beschädigungen führen kann, ist unbedingt eine ausreichende Schmierung auch dieser Bereiche erforderlich. Es sind deshalb Schmiernuten schrägliegend in die Buchse eingearbeitet, welche mit im dicken Teil der konischen Buchse angeordneten Zuführnuten in Verbindung stehen. Während des Betriebes wird von dem ständig zwischen die Buchsen eingebrachten Öl in der Lastaufnahmezone des Ölfilmlagers auf hydrodynamische Weise ein Hochdruckölfilm erzeugt und über die Zuführnuten eine Teilmenge davon den Schmiernuten zugeführt. Die Walzendrehung ruft Zentrifugalkräfte hervor, die das Öl aus den Schmiernuten in Richtung der Mantellinien austreten läßt und für eine umfassende Ölverteilung sorgt.
