Patent DE-3523178-A1 (DE)
Title: Contact tube with wire cleaner
Inventor: PACHE NORBERT
IPC: B23K9/12
Filed: 1985-06-28
Abstract: In order to reduce the dirt which collects in the contact tube, results in poor current transfer and blocks the contact tube hole, so that further transportation of the welding wire is prevented, an elastic, heat-resistant material is installed in the wire-inlet opening of the contact tube. The welding wire is pushed through this material during insertion into the contact tube. In this case, the elastic material loops around the welding wire over its entire circumference. The dirt which is located on the wire surface is stripped off. No dirt can penetrate into the contact tube. This results in a constant (contact tube/welding wire) current transfer and reliable transportation of the welding wire.
Patent DE-3525117-A1 (DE)
Title: Propulsion drive for aircraft and ships
IPC: B63H11/08
Filed: 1985-07-13
Abstract: Time is money, especially for shipping companies. In order to accelerate ships and aircraft, the driving media air and water are to be combined for driving in a rolling motion. For this purpose the propeller in ships is to be replaced by a threaded tube, which tapers rearwards like a funnel. Due to its rotation the masses of water are to be forced to flow much faster through the end of the tube than they flow in, since water is incompressible and the inlet orifice of the threaded tube rotating at high speed is, by virtue of its funnel shape, much greater than its outlet orifice. Instead of nozzles, aircraft are to have a propeller motor with the axis directed rearwards and in this way air is to be compressed in the threaded tube rotating at high speed in order thereby to release much more propelling force and to generate more thrust than with conventional propellers.
Patent DE-3528621-A1 (DE)
Inventor: SCHREIBER HANS DR DR
IPC: A61C19/05
Filed: 1985-08-09
Abstract: Recording device for determining the position of the lower jaw in relation to the upper jaw during central occlusion. Three parallel-arranged sleeves (Fig. 2.1) each provided with a thread are polymerized on the individually-produced imprint spoon (Fig. 1.1) and equipped with screws, the length of which can be adjusted by modifying the screwing-in depth. With the additional aid of a correspondingly-shaped bite-fork it is possible to fix with these screws a recording indicator plate (Fig. 7) in the occlusion plane of the patient. The recording indicator plate is equiped with an extension to receive a transfer base (Fig. 7.6). The functional spoon for making the imprint of the lower jaw is provided with three or four parallel-arranged pins (Fig. 4.2) allowing the acceptance of a plate that carries a recording stylus (Fig. 3.1) which, depending on the operating pressure in the lower jaw, is varied in height in such a way that, after contact has been made by the recording stylus on the upper jaw recording indicator plate, the patient exhibits a jaw separation of 2-3 mm under the suspension position at rest, and in such a way that depending on the colour-mmarking of the upper jaw recording indicator plate, it is possible to record the arrow angle in a typical manner. To code the recording, use is made of a modified pen plate which ensures that the pen can reproduce the acquired arrow angle (Fig. 7.1) at the same height and same position. A wedged-shape accessory (Fig. 7.2) ensures, after fixing on the recording plate by linear application on the modified recording stylus plate in combination with locking of the stylus, reliable three-point support and coding of the recording.

Title: Protective support for ornamental plates
IPC: A47G1/16
Filed: 1985-08-16
Abstract: To protect ornamental plates of fragile material an ornamental plate is firmly enclosed in a protective frame which corresponds to the edge shape and the edge diameter or only to the edge diameter and is made of shock-absorbing material. The plate is supported such that it cannot move, in the first case, in a groove which is formed between the frame and a front plate-edge holding plate, or in the second case, from the rear by a blocking plate against a fold on the inner edge of the frame. By the latter means plates of different depth can be accommodated in the same protective support. The protective support can be used both for hanging up and for standing up the plate and at the same time serves as a decorative frame for the ornamental plate.

Title: Back-edged saw chain
Inventor: LINKE WILFRIED
IPC: B27B33/14
Filed: 1987-12-19
Abstract: In back-edged saw chains, to avoid kick-back effects safety links which run ahead of the cutting tooth and are supported on the cutting base by a nose-shaped elevation are provided. Even in the case of chains constructed in this way, in practice kick-back effects still occur, putting the operator and persons standing nearby at considerable risk. According to the invention, provision is made for the safety link to be equipped with a nose extending opposite the running direction to the cutting tooth and overlapping the depth limiter of the cutting-tooth link. The nose has a portion which slopes counter to the running direction and moves onto the cutting circle in the deflecting region. The invention can be used for saw chains of motorised chain saws.
