Title: Filter element for fluids and process for producing a filter element
Inventor: HOFFMANN JUERGEN DR
IPC: B01D63/08
Filed: 1987-04-15
Abstract: In a filter element (8), which can be enclosed in a filter housing having feed and discharge connections for fluids, each two filter sections (9) lying one above the other having a support layer (10, 11) are joined by an annular closed leak-proof joint (17), within a surrounding relatively large peripheral filter surface, by welding or adhesion. The inner annular surface enclosed by this has a passage (16) for conducting fluid at right angles to the filter surface. To form a layer and joint geometry in the manner of a Chinese lantern, each of the mutually adjacent filter sections (9) of adjacent filter section pairs are likewise joined together in a leak-proof manner by welding or adhesion at their peripheral edges (17'), one side (outer Chinese lantern side) of all joined filter sections (9) having support layers (10, 11) opening out into the housing chamber and the other side (inner Chinese lantern side) of all joined filter sections (9) having support layers (10, 11) opening out into the other housing chamber via the passages (16). <IMAGE>

Inventor: TEMELLI SEDAT DIPL ING
IPC: F23J7/00
Filed: 1987-05-14
Abstract: The invention relates to a method of burning in particular refuse, and a combustion boiler (1) in particular for the refuse combustion, materials to be burned being fed into a furnace body (2) and burned on a furnace grate (3) in the furnace body (2), the resulting flue gases being drawn off from the furnace body (2) and swirled by the addition of secondary air, and post-combustion of the flue gases taking place. In this connection, the secondary air is injected into the post- combustion zone over the entire flow cross-section of the flue gases, before the entry of the flue gases, in such a manner that the flue gases are braked, i.e. retained in a uniform temperature zone of the furnace body (2) in the exhaust direction before the injection region.

Title: Process and apparatus for mixing a gas with a liquid
Inventor: WEBER WERNER DR
IPC: B29B7/76
Filed: 1987-06-25
Abstract: To mix a gas with a liquid, in particular with a reaction component for the production of foams based on polyurethane, an eddying motion is generated in the liquid by the rotary motion of a central stirring tool (2) guided into the vessel (1) from the top and gas situated on the surface of the liquid is introduced into the liquid. The liquid-gas mixture is exposed to local pressure variations by means of a dispersion element (3) which is eccentrically arranged in relation to the vessel axis and rotates at a frequency of 1000 to 7000 min to the power -1. In this manner, a particularly homogeneous liquid-gas mixture can be produced with high gas contents. <IMAGE>

Patent DE-3741151-A1 (DE)
Title: Method for determining errors in a digital transmission system
Inventor: FRENZ GERHARD
IPC: H04B17/40
Filed: 1987-12-04
Abstract: In the method described for determining errors in a digital transmission system with repeater stations, it is assumed that a testing terminating exchange sends out a fault locating signal instead of the useful signal. The fault locating signal contains a test pulse pattern and information on the address of a repeater station to be located. The address is recognised in the repeater stations either digitally by means of counters or by analogue means with filters. The filters respond to frequencies which are contained as fundamental frequency in the pulse density fluctuations of the fault locating signal. To obtain as large a set of addresses as possible, by means of which both repeater stations with analogue and with digital address recognition can be located, it is provided to build up the fault locating signals on two bit patterns. The first bit pattern consists of a first bit sequence which is followed by the totality of all inverted bits of the sequence and the second bit pattern consists of a second bit sequence which is only followed by some of the inverted bits of the sequence. The number of inverted bits of each second bit pattern should be smaller than the smallest number of the inverted bits of all first bit patterns. The fault locating signals consist either of the periodic repetition of the first bit pattern or of the period repetition of the second bit pattern.

Patent DE-3806837-A1 (DE)
Title: Motor vehicle
Inventor: BEHLES FRANZ DR
IPC: B60G99/00
Filed: 1988-03-03
Abstract: The motor vehicle has a vehicle body (1) enclosing the passenger compartment. In order to be able particularly well to insulate the vibrations and noises caused by the drive assemblies but also transmitted via the running gear, relative to the vehicle body (1), the front section (2) and/or the rear section (3) of the motor vehicle is designed as a chassis sub-frame. The front section (2) or the rear section (3) is, to this end, connected flexibly to the vehicle body (1) via rubber elements (7, 8, 9, 10 or 23, 24, 25, 26). The engine-gearbox unit (4) is supported on the front section (2) via the rubber bearings (11, 12, 13). The rear-axle assembly (6) is likewise flexibly connected to the rear section (3) via the rubber bearings (27). Since the front section (2) and the rear section (3) each have a substantially higher mass than the previously known chassis sub-frames or auxiliary supports, particularly good insulation against vibrations and noises can be achieved without more constructional space or a substantially higher additional weight being required for this purpose. <IMAGE>

Title: Method for measuring a coil with losses and inductive distance sensor constructed in accordance with this method
Inventor: BECKER WOLF-JUERGEN PROF DR
IPC: G01B7/02
Filed: 1988-04-27
Abstract: The invention relates to a method and a device for measuring the losses, present in an electrical magnetic radio-frequency field, of a coil with losses by inserting an attenuator, for example a control tab of electrically or magnetically conductive or ferromagnetic material, so that the dependence of the coil Q on temperature is no longer included in the measurement of the attenuation. For this purpose, the resistance of the field loss impedance due to this attenuation is measured independently of the winding loss resistance and independently of the reactance of the coil. The simplest possibility is measuring the active power in this field loss impedance. The use of such a measuring method is particularly advantageous in inductive proximity and distance sensors.

Inventor: PRICE DAVID JOHN
IPC: G01S13/24
Filed: 1988-04-27
Abstract: A radar for deriving the range profile of a complex target has a voltage controlled oscillator 1 frequency stepped by a control circuit 2, the output being fed via a circulator 4 to PIN diode switch 5, open during transmission periods, allowing the VCO output to reach the pulsed amplifier 6, with controlled pulse width and repetition frequency. The output pulses are fed via the duplexer 7 to the antenna 8, received returns from target 20 being fed via the duplexer 7 to the mixer 9 and thence to the IF amplifiers 10 where they are frequency analyzed by FFT 15. During the reception period, the VCO is frequency switched and provides the local oscillator frequency offset from the received returns. After integration of the digitised returns from several pulses at each transmission frequency, they are stored for Fourier transform processing and measurement with, and without, external scatterer 21 present. <IMAGE>

Title: Aqueous adhesive mixture for gluing cigarette-paper seams
Inventor: BRECHTEL GERHARD DIPL CHEM
IPC: C09J103/04
Filed: 1989-05-03
Abstract: The invention relates to an aqueous adhesive mixture and to a process for its preparation, based on chemically modified starch, for application to cigarette paper to glue cigarette-paper seams. The aim of the invention is to utilise fully the capacity of cigarette machines by improving the gluing of the cigarette-paper seams. The object of the invention consists in providing a starch-based adhesive mixture which is soluble in cold water and has a high adhesive capacity and a shorter setting time. According to the invention this is achieved in that said mixture comprises 15-30 % by mass of a carboxymethyl ether of potato starch having a degree of substitution of 0.1-0.25, some of the carboxyl groups of the compound being linked in the manner of esters to the hydroxyl groups of neighbouring molecules, and the free carboxyl groups being in the form of the sodium salt. This modified, pulverulent carboxymethyl starch is mixed intensively, in accordance with one process feature of the invention, with the total quantity of water to give a homogeneous, gelatinous mass and, after a swelling time of 1-24 hours, is transferred to the appropriate glue-holding container of the gluing apparatus.
