Title: Metal-cutting sawing machine
Inventor: SUGIMOTO TADAHIRO
IPC: B23D53/08
Filed: 1982-10-04
Abstract: A device for producing rocking movements is part of a metal-cutting sawing machine and enables the saw blade to perform rocking movements in a cutting plane in which a workpiece is to be cut through, the rocking movements being controlled in such a way that they are adapted to the length of the cutting line which is determined according to the shape and size of the workpiece. In contrast to known metal-cutting sawing machines, in which the saw blade partly performs idle movements relative to the workpiece, the sawing machine ensures that the saw blade is in each case moved in such a way that such idle movements are avoided.

Title: Glider with a removable auxiliary engine
Inventor: FISCHER THOMAS DIPL ING
IPC: B64C31/024
Filed: 1982-12-06
Abstract: A glider which was not originally designed as a motor-glider can be converted into a motor-glider by fitting an auxiliary engine according to the invention and connecting it to permanently installed control elements. The engine support and propeller of the installation have a variable geometry, and are moved into a low-drag not-in-use position for gliding. No modifications are required to the primary structure of the existing glider. Disturbing moments when the engine is running can be reduced by directing the propeller flow obliquely onto the control surfaces. The necessary energy stores, such as a tank and battery, are housed in the installation which can be fitted. After removal of the auxiliary engine, a pure glider is obtained again.

Title: Method and device for detecting the presence or absence of a substance at a detector or the distance between substance and detector
Inventor: DREHER WOLFRAM
IPC: G01F23/296
Filed: 1983-02-08
Abstract: The detector used in this method is a device (1,2) capable of oscillating, the natural oscillations of which are influenced by the substance. In a calibrating phase, after the device has been excited into oscillation for a short time, measurement values are detected during the period of the natural oscillations and permanently stored as reference values. The reference values in each case refer to a previously accurately determined reference state with respect to the distance between substance and detector or with respect to the presence or absence of the substance at the detector. During later excitations of the device (1,2) into oscillation, measurement values are compared in-phase with the reference values in order to detect the presence or absence of the substance at the detector or the distance between substance and detector via the correspondence or the differences. <IMAGE>

Patent DE-3312421-A1 (DE)
Title: Soldering bit with automatic solder feed
Inventor: ARMONIES GERHARD DIPL ING
IPC: B23K3/03
Filed: 1983-04-07
Abstract: The invention relates to a temperature-controlled soldering bit with automatic solder feed. The solder is conveyed by a motor/pinion counterbearing system into a solder-liquefying chamber. The liquid solder then passes through a bore to the tip of the soldering bit and wets the tip there. By the actuation of the pinion (1) by means of an electric motor (2) and a spring-mounted counterwheel (3) as counterbearing, the solder (4) is conveyed through the polymer guide (5) into the heating chamber (6) by the motor voltage UM being applied to the motor (2). This is done by a transistor circuit which always switches through the transistor (8) when no solder electrically connects the two contacts (9) and (10) to one another. This ensures that the heating chamber (6) up to the contacts (9) and (10) is always filled with the solder (4). The heating chamber (6) is located as a bore in the front part of the tip (11) of the soldering bit. Arranged in the heating chamber (6) is a temperature sensor by means of which the soldering temperature is controlled. A bore (13) of a certain diameter and certain wall roughness is made between the heating chamber (6) and the tip of the soldering bit. The liquid solder passes through this bore (13) by capillary action or the force of gravity to the tip of the soldering bit and is partly distributed at the rounded portion of the tip of the soldering bit by wetting. When the tip of the soldering bit heated to operating temperature is ... Original abstract incomplete. <IMAGE>

Patent DE-3316900-A1 (DE)
Title: Device for the output of pages, sheets and the like
Inventor: KOBAYASHI TETSUJI
IPC: B65H3/04
Filed: 1983-05-09
Abstract: The invention relates to a device for the output of page-like or sheet-like material, such as banknotes, a banknote delivery unit delivering a banknote stored in a banknote storage unit, and a banknote sensing section ascertaining whether the delivered banknote is deliverable (normal) or has been torn, folded or otherwise damaged (abnormal). In this process, a normal banknote is fed to a first holding unit and/or a box, while an abnormal banknote is guided into a second holding unit. When a preset number or a preset sum of banknotes has been stacked in the first holding unit, the bundle of notes comprising normal banknotes is fed to an outlet. If, however, malfunctions occur in connected devices or in connected transmission channels, the normal banknotes are transferred from the first holding unit into a return unit, before or after a preset number of normal banknotes has been stacked. The abnormal banknotes temporarily stored in the second holding unit can be transferred to the return unit after the normal banknotes stored in it have been removed. In this way, the output of banknotes is made substantially easier.

Title: Protection tube for electrical cables
Inventor: SCHOENGEN KARL
IPC: H02G9/06
Filed: 1984-01-24
Abstract: A protection tube (1, 2) for electrical cables which are laid underground is characterised on its two end regions by mutually complementary recesses (3, 4) and residual walls (5, 6) in the region of these recesses, so that the end regions of the protection tubes (1, 2) can be plugged into one another. This tube connection is particularly suitable for an operating procedure in which the protection tubes are laid underground by driving them in in the longitudinal direction, since, in the region of the respective tube connection, there is neither any weakening of the wall thickness nor is the driving in of the protection tubes adversely affected by obstructions projecting from the outer surface of the protection tubes. <IMAGE>
