Patent DE-3213185-A1 (DE)
Title: Saw for cutting trees or the like
Inventor: SCHMIERER HEINZ DIPL ING
IPC: B27B19/09
Filed: 1982-04-08
Abstract: A saw for cutting trees or the like is described, which consists of a telescopic tube with an internal combustion engine arranged on one side and with a saw cutter on the other side which is caused to move to and fro by a transmission, in which the transmission is driven by the motor via a telescopic shaft. The telescopic shaft is supported radially in the outer pipe of the telescopic tube via a bearing which is guided longitudinally displaceably on the tube wall and on the telescopic shaft and is pressed into an axial end position by a pressure spring surrounding the telescopic shaft. This design has the advantage that an intermediate bearing can be provided on the inner telescopic shaft part at a given distance from the lower driven end, if telescopic tube and telescopic shaft are extended to full length. This intermediate bearing does not, however, prevent the pushing-together process which is important for the optional length adjustment of the saw.

Patent DE-3226372-A1 (DE)
Inventor: BARRY JUERGEN
IPC: G01N21/47
Filed: 1982-07-14
Abstract: In known apparatus for taking reflectance readings the accuracy is very highly dependent on the distance between the transmitter and/or receiver area, on the one hand, from the surface whose reflectance is to be measured on the other. In the invention, in the field of measurement, the beam from a transmitter has superimposed on it the beam of at least one further transmitter so that within a wide range of operation readings are made independent of the distance between the said field on the one hand and the transmitter and/or receiver plane on the other and for this reason there is a deep range of measurement, that is to say compensation of depth. Preferably the transmitters are placed axially symmetrically with respect to the axis of the received beam (beam coming from the sample) or planarly symmetrical with respect to a plane containing the axis of the said beam.

Patent DE-3229872-A1 (DE)
Title: Voltage multiplier
Inventor: HAUSER MARKUS
IPC: H02M7/10
Filed: 1982-08-11
Abstract: The invention relates to symmetrical voltage multipliers having rectifiers and capacitors arranged in balanced cascades. Balanced voltage multipliers are known which operate in the centre tapping of transformer windings and inductor coils. However, such known voltage multipliers have the disadvantage that the number of turns on the primary windings of the transformer must be kept twice as great, since the voltage to be multiplied is on the one hand positive and on the other hand negative with respect to the centre tap, that is to say it must be present twice. The invention is based on the object of creating a method of construction or circuit for voltage multipliers, by means of which the material cost for winding copper can be kept small. The object is achieved in that, at the inputs (5) of a two-pulsed cascade (4), there is arranged in each case one feedback rectifier (7) which with its one end forms a common earth point (6), the rectifiers (8) are connected in a crossover circuit in each of the cascade stages (4' to 4<n>) and the voltage with respect to the common earth point (6) can be picked off at the output (15) of the cascade (4). <IMAGE>

Title: Internal combustion engine supercharged by an exhaust gas turbo-charger
Inventor: STIERMANN ERWIN DIPL ING
IPC: F02M26/36
Filed: 1982-12-04
Abstract: In the case of an internal combustion engine supercharged by an exhaust gas turbo-charger, a bypass line is laid between the charge air manifold and the exhaust gas manifold. A combined bypass/blow-off device is proposed for this purpose which incorporates a blow-off valve and a bypass valve. This device comprises an axially displaceable bypass valve connected into a bypass line, to which valve a passage control element is assigned. The latter has a passage duct for bypass charge air and a valve seat for the bypass valve. In addition the said passage control element is designed and arranged in the bypass line in such a way that it can also assume the function of a blow-off valve. The design and arrangement are at the same time so selected that following a shut-off of the passage duct by the bypass valve then lying on its valve seat it can be displaced under the action of the said bypass valve against a return force and is capable of opening a blow-off line by moving off an associated valve seat. This line branches off from the bypass line in the area of the passage control element and is separated off from this by appropriate means which prevent migration of charge air into the blow-off line and migration of exhaust gases from the blow-off line into the closable part of the bypass line.

Patent DE-3329967-A1 (DE)
Title: Screwed or riveted connection
Inventor: WAGNER HANS PETER
IPC: F16B37/00
Filed: 1983-08-19
Abstract: The invention relates to a screwed or riveted connection which connects various components, which rest on one another, to one another along a contact gap. The components are provided with a coating, even in the contact region, which coating prevents corrosion and is softer than the basic material, especially with a varnish. In the contact gap, a washer is placed around the screw or rivet shaft, which washer, on its flat side facing the varnished contact surface, is provided uniformly with blade-like beads which penetrate through the varnish down to the basic material, or with a large number of acute-angled pyramids. The washer material has at least approximately the same hardness as the basic material of the components which are to be connected. Such washers are intended to contribute to reducing the appearances of settlement in dynamically stressed screwed or riveted connections having varnished clamping surfaces. In this case, the washers can be fitted both in the contact gap of the clamping surface as well as under the screw or rivet head and/or under the nut.
