Patent DE-3230680-A1 (DE)
Title: Sewer cleaner
Inventor: STEINWELLER GERT DIPL ING
IPC: B08B9/04
Filed: 1982-08-18
Abstract: The sewer cleaner has been developed for removing solid deposits in large pipes, operated at low flow rate, for the transport of solids-containing liquid media . This device carries out two operations simultaneously   a) loosening the solids and simultaneously mixing them with the liquid medium present to form a pumpable emulsion by means of vibratory rakes and b) the transport of this emulsion out of the particular pipe section using a suitable pump unit and appropriately dimensioned transport line. The prerequisite for this cleaning operation is that an adequate amount of liquid is present in the pipe section to be cleaned, since the liquid must assume the function of carrying the loosened solids to be transported. The sewer cleaner is designed such that it can be introduced through the narrowest access openings of the large pipes and used with low time consumption. The forward movement of the device in the section to be cleaned is carried out by rope traction. The energy consumption required to operate the device is low in comparison with the cleaning processes hitherto known. e

Title: Internal combustion engine for a motor vehicle
Inventor: GONTSCHAROW WALDEMAR
IPC: F01M5/02
Filed: 1982-09-23
Abstract: Arranged within an oil sump (10) is a cup (16) which is connected via a pipe (14) to an oil pump (12). Arranged in the pipe (14) is a thermostat (26) which acts on a bell-shaped valve (24) which, depending on the oil temperature, opens the space within the cup (16) or the space outside the cup (16) and the corresponding quantities of oil for suction by the oil pump (12). An oil-catching plate (34) arranged above the cup directs the dripping oil always into the cup (16), from which it can overflow into the space outside the cup. When the engine is cold, the lower base (22) of the bell-shaped valve (24) closes the bottom opening (20), with the result that the oil is supplied within a small circuit to the lubrication points. When this small quantity of oil reaches a certain temperature, the thermostat is activated, the bell-shaped valve (24) thus being displaced downwards in order to connect the pipe (14) to the large quantity of oil. <IMAGE>

Patent DE-3249210-A1 (DE)
Title: Device for connecting two pipe ends
IPC: F16L23/04
Filed: 1982-11-11
Abstract: The invention relates to a device for connecting two pipe ends, having a collar part which is allocated to one pipe end and into which an insertion part allocated to the other pipe end can be pushed. The collar part and insertion part are surrounded by a clamp which has inwardly projecting flanges on the sides. In order that the collar part does not have to have excessively strong dimensions in the event of a relatively high operating medium pressure, a support, extending in the radial direction, is intended to be provided according to the invention between the collar part and the clamp, via which support a proportion of the stresses which act on the collar part and are caused by the operating medium pressure can be transmitted to the clamp. In consequence, a correspondingly weaker design of the collar part becomes possible.

Title: Round-bale loading and transport vehicle
Inventor: BILLER BERND
IPC: A01F15/08
Filed: 1983-02-08
Abstract: Round-pressed bales (4), after being produced, pass out of the round-bale presses (1) rearwards or laterally and rest scattered in the fields. Recovery involves a very high outlay, and on slopes the round-pressed bales roll away in an uncontrolled manner, thus making recovery more difficult, whilst the round-pressed bales (4), field fences and the like can be damaged and there is a great danger of accidents to humans and animals. To avoid these disadvantages, there is proposed a round-bale loading and transport vehicle (3), with which either the round-pressed bales (4) passing out of the round-bale presses (1) at the rear are received in limited numbers, for example 2 to 5 items, during production, without interrupting the bale production, and deposited at the field edge or at the storage location by rolling down, or, for picking up round-pressed bales (4) discharged laterally or already lying in the field in a row, the round-bale loading and transport vehicle (3) is suspended on the round-bale press (1) or on a tractor in a manner offset in terms of the track by means of a pivoting drawbar (10) and picks up the round-pressed bales (4) from the ground in a fully automatic mode of operation. <IMAGE>

Patent DE-3328890-A1 (DE)
Inventor: WINCIERZ PETER PROF DR
IPC: F16B19/04
Filed: 1983-08-10
Abstract: Rivets for use in the aircraft industry are made from a wrought aluminum alloy (Material No. 3.1324 in accordance with DIN). As that alloy will precipitation-harden at room temperature, the rivets must be closed immediately after they have been annealed and quenched. The time in which the rivets can be deformed can be extended to as much as one week if the rivets are stored below -17 DEG  C. In order to overcome said disadvantages in the processing of the rivets, 0.002 to 0.3% cadmium is added to the wrought aluminum alloy. The resulting modified material exhibits a delayed precipitation hardening at room temperature and even when it is fully precipitation-hardened has a very high ductility. For this reason the precipitation hardening will not impose restrictions as regards the time in which rivets made of said alloy can be closed.

Patent DE-3408001-A1 (DE)
Title: High-power wind-energy system suitable for high speeds
Inventor: JAECKEL ERNST
IPC: F03D1/06
Filed: 1984-03-03
Abstract: The high-power wind-energy system suitable for high speeds solves the problem of mastering high rotational speeds by excluding any lifting or forward torques of the wind wheel in favour of reliable operation which is smooth and has a correspondingly high power, and of high stability of the system. The high rotational speed is produced by the interaction of the many driving vanes as they absorb all the compressive and suction forces of the wind, which are evenly matched to the circumferential speeds of the wind wheel, which increase from inside and outside, as well as to the fluctuations and peak values of the wind strength and exhibit their best possibilities for exerting influence in a feathering of the outer skin of the driving vanes, all of which results in a high power output.
