Patent DE-3401244-A1 (DE)
Title: Magnetic motor
Inventor: KOERNER HELMUT
IPC: H02K53/00
Filed: 1984-01-16
Abstract: The subject matter of the invention is a magnetic motor (magnet motor) having permanent-magnet parts, without any coils, for producing torque, which motor can produce drive work for widespread purposes without it being necessary to supply any electrical power. This motor has this capability as a result of the fact that at least one screen of a specific material and of a specific wall thickness is provided for interacting groups of magnetic parts, which screen is intrinsically located between the pole surfaces of these parts in a movement phase of said parts from their maximum mutual proximity, and screens them from one another while a specific arc angle is passed through. This arc angle is cyclically adjacent to another specific arc angle for opening the magnetic parts with respect to one another through at least one recess in the screen or through a position offset, as a result of which these parts can mutually absorb the magnetic field lines (lines of force) as they approach, to produce torque.

Title: Appliance for pressing a crop
Inventor: BAHLMANN HANS-HERMANN
IPC: A01F15/04
Filed: 1984-03-02
Abstract: In an appliance for pressing a crop into bales having a rectilinearly limited base surface and side surfaces perpendicular to this, a tubular first press channel of rectangular cross-section is provided. In its longitudinal direction, a compression piston acts in the direction of the crop introduced into the press channel. Shaping forces are introduced into the crop from the side walls of the press channel. The compression piston is mounted inside the press channel so as to be displaceable in the longitudinal direction of the press channel. The latter compresses the crop. Fastened to the press channel is a pushing-out device mounted so as to be displaceable transversely relative to the longitudinal direction of the press channel. This pushing-out device stresses the bale standing on its base surface and opens into the first press channel opposite a pushing-out gate, through which the bale is pushed out of the press channel. There is a second press channel, the design of which corresponds essentially to that of the first press channel and which is oriented in the same way as this and is arranged next to the first press channel. The pushing-out device of the second press channel is mounted displaceably in the same directions as the pushing-out device of the first press channel.

Title: Hydraulic gear motor
Inventor: RUSTIGE HAYNO DIPL ING
IPC: F01C19/08
Filed: 1984-08-17
Abstract: The hydraulic gear motor has two gears (14, 15) meshing with one another in outside engagement, on the side faces of which a pressure-actuated sealing plate bears. Actuation is performed by pressure fields (40 to 42) which are built up on the side of the sealing plate (26) remote from the gear side faces. These are two pressure fields lying approximately concentric in relation to one another, one of which (the outer) is actuated first when starting up the hydraulic gear motor, followed by the inner (42) some time later. In this way a phased pressing of the sealing plate onto the gear side faces is obtained, which results in good starting behaviour of the hydraulic gear motor. <IMAGE>

Title: Process for controlling the carbon level in a gas carburisation furnace
Inventor: DENZER ALWIN
IPC: C23C8/22
Filed: 1984-10-03
Abstract: In a process for controlling the carbon level in a gas carburisation furnace, which is fed with a carburisation gas in the form of a carrier gas and an enriching gas in controlled quantities, it is provided that the quantities of carrier gas and enriching gas are initially fed to the carburisation gas at a base setting. Subsequently the carbon level which is established as a function of the size of the surface area of the workpiece which is to be carburised is recorded and adjusted to a set value. If excess carbon is available, the quantity of enriching gas is reduced. In the case of carbon deficiency, the quantities of carrier gas and enriching gas are increased while retaining a fixed ratio.

Title: Double-tube heat exchanger
Inventor: EGELER DIETER
IPC: F28D7/02
Filed: 1984-11-27
Abstract: The double-tube heat exchanger serves, in particular, as a petrol cooler for installation in motor vehicles. The coolant, which is under a relatively high pressure, flows through an inner tube (1), while the medium to be cooled flows through the clearance space between the inner tube (1) and an outer tube (2). The clearance space is in the form of a helical recess (4) on the outside of the inner tube (1), with the result that, to the side of the recess (4), the outer tube rests directly on the inner tube (1). As a result, the outer tube (2) reinforces the strength of the inner tube (1) in relation to pressure loads exerted by the coolant and simultaneously improves the heat transfer between the coolant and the medium to be cooled.
