Patent DE-3724410-A1 (DE)
Title: Electrically heatable fuel filter
Inventor: BAUMANN DIETER DIPL ING
IPC: F02M37/22
Filed: 1987-07-23
Abstract: Known fuel filters which are electrically heatable are constructed in a complicated fashion from a large number of components and/or are very limited in their efficiency. The new fuel filter is intended to be of very simple construction, cost-effective to manufacture and efficient. The new electrically heatable fuel filter is characterised in that a housing section (3) has a heating element (4) with a fuel duct (41) meandering through this and with at least one heating resistor (46) mounted on or inserted in the element (4) in a thermally conductive connection. The fuel is effectively heated inside the relatively long duct since, on the one hand, the fuel retention time in the heating element is relatively long and, on the other, the surface of the heating element transmitting the heat to the fuel is large. The housing section with the heating element can advantageously be manufactured by the die-casting process, which makes it very cost-effective to manufacture. The new electrically heatable fuel filter is especially suitable for motor vehicles with a diesel engine and for other appliances, driven by a diesel engine, which are exposed to low temperatures. <IMAGE>
Patent DE-3731329-A1 (DE)
Title: Metal detector
Inventor: MANNESCHI GIOVANNI
IPC: G01V3/10
Filed: 1987-09-17
Abstract: A detector for metallic masses is proposed, which has transmitter and receiver windings which correct the non-uniform distribution of the electromotive forces (EMF) which are induced upon the passage of a metallic mat through a monitoring batch (lot). The detector is arranged in such a way that it indicates the passage of metallic objects, in particular of weapons. It is characterised by the combination of two pairs of windings composed in each case of a transmitter and a receiver which are arranged opposite one another and on either side of the monitoring batch, transmitter and receiver being arranged on the opposite sides of the monitoring batch, and amplifier blocks which act on the received signals, which are in turn controlled by a logic unit for the purpose of analysis and control. The logic unit for analysis and control is capable of processing at least the signals induced in the receiver windings and, if necessary, of influencing the amplifiers, which subject the signals to a correction with the aid of coefficients proportional to their difference, or of acting in some other way on the received signals in order to render them essentially independent of the distance of the moving metallic mass from the receiver windings.

Patent DE-3740759-A1 (DE)
Title: Chopper with friction roller
IPC: A01F29/02
Filed: 1987-12-02
Abstract: To provide a chopper at a low outlay in terms of construction, along with a low power requirement and a high degree of grain comminution, it is proposed to provide on the circumference of the cutter wheel or cutter drum a rotatable friction roller which projects with a part region through the housing retaining wall and extends near to the circle of rotation of the throwing shovels or beating implements to form a friction gap. The rotation of the friction roller ensures a reduced drive power of the chopper and a self-cleaning of the friction grooves, so that these are always effective and therefore improve the grain comminution.

Title: Throwing-game machine
Inventor: FROSCH HEINZ-THOMAS
IPC: G07F17/32
Filed: 1988-08-04
Abstract: The patent application relates to a machine intended for a throwing game, called a throwing-game machine. The machine consists of two parts which stand one on top of the other in a T-shaped manner. The upper part has three compartments for setting up the knock-down containers which are knocked down by balls. The rear and side walls of the upper part are designed so that the balls and containers fall into the machine as a result of the corresponding inclination. The side slopes adjoin the lower exit of the back slope and the pyramidal setting-up surface. A catching space is formed under the setting-up surface and receives balls arriving underneath the setting-up surface. It opens directly into the lower part. The entire throwing material collects on the stop flap. The latter is retracted during the operation of the pressure shaft, the shaft catching on a toothed ring by means of the shaft teeth. A disc is located on the toothed ring. This disc is rotated by the toothed ring. A pull is attached to the disc and reaches as far as the stop flap. By rotating the disc, the flap is pulled up and the throwing material can fall into the dispensing shaft. Springs pull the pressure shaft back after the pressing operation. Springs likewise pull the stop flap into the closing position.

Patent DE-3901592-A1 (DE)
Title: Interference refractometer
IPC: G01N21/45
Filed: 1989-01-20
Abstract: The definition of the metre of 1983 defines the basic unit of length as the transit time of a frequency in vacuum. For its realisation, the length is measured interferometrically with a known and stable frequency. In order to take into account the influence of the refractive index of the air on the wavelength, this must be measured in an interference refractometer. The refractometer consists of an air chamber and a vacuum chamber as reference, in which the conditions of the definition of the metre can be realised. The length or the change in length of the vacuum chamber can be determined in its position of use with the wavelength in vacuo of the defined frequency, measuring the path or measuring the distance. By this means, systematic errors, which are produced during construction and commissioning of conventional refractometers, are excluded and the accuracy is increased. Figure 2 shows the typical construction of two variants: (4) is a polarisation - optical differential interferometer, to which the vacuum chamber (1) is connected, with the sealing mirror plate (3). For path measurement, the vacuum chamber consists of a bellows and the plate (3) is moved, for the distance measurement it is rigid. <IMAGE>
