Patent DE-3049343-A1 (DE)
Title: Heated applicator gun for hot fusion adhesives - has PTC resistor in plug-in cartridge parallel to adhesive channel
Inventor: STEINEL HEINRICH WOLFGANG
IPC: C09J5/00
Filed: 1980-12-29
Abstract: The gun has a resistance heater (23,24) comprising an element with a positive temp. coefft. of resistance. This element may be a cartridge comprising an elastic, flexible, heat resistant sheath and a PTC bulk resistor held between two or more pressure pieces. A spring arrangement acts on the cartridge and ensures uniform thermal and electrical contact independently of changes in dimension. The PTC resistor extends over at least 3/5 of the guide channel (14) into which the solid rod of adhesive (16) being melted is inserted. The advantage lies in uniform heating and therefore a uniform viscosity to the outgoing adhesive.

Title: Warm water system for motor vehicles for cleaning the headlights, windscreen and rear window
Inventor: UENALDILAR SOEZERI
IPC: B60S1/48
Filed: 1981-01-09
Abstract: By means of this invention, an additional container made of zinc with a casing thickness of approximately 0.8 to 1 mm is attached to the coolant container in motor vehicles and supplies warm water for the window washing and wiping system. This additional container is installed directly on the side of the existing coolant container so that warm water is always available in the additional container for the washing system through the side wall of the coolant container (heated cooling water) and the windows can be kept clean with warm water. The previously existing cooling system of the passenger car remains unchanged. Even only a short time after the start of the engine, it is thus ensured that both the cooling water and the water supply for the window washing system are heated up so that even a short time after the start of a journey warm water is available for the washing system. Since the additional container with warm water for the window wiping system is attached directly to the existing radiator, the small plastic container in which the water has hitherto been stored for the washing system will in future be dispensed with. Otherwise, the window washing system is preserved in the same form as in the past. The invention provides substantially greater safety for the car driver and road traffic.
Patent DE-3101221-A1 (DE)
Title: "Froth flotation device"
Inventor: SCHWEISS PETER
IPC: B03D1/24
Filed: 1981-01-16
Abstract: Device for froth flotation of suspensions, especially of fibre suspension, in which the suspension, laden with air by means of an injector which has an essentially tubular mixing chamber, is supplied from the mixing chamber to the flotation vessel, characterised in that the outlet orifice(s) of the tubular mixing chamber are directed towards the bottom of the flotation vessel and are located at least approximately in the central axis and near the bottom of the flotation vessel, and in that the latter has an annular discharge cross-section for the discharge of the suspension from the flotation vessel, which is arranged so as to encompass the latter on its outside, seen radially. Owing to the flow conditions in the, if possible, at least approximately circular-cylindrical flotation cell, which result from this arrangement, strong infiltration of the suspension with very fine air bubbles is achieved with little energy input. The main field of application is the paper industry.
Patent DE-3101394-A1 (DE)
Title: Vacuum pump and its arrangement
Inventor: SCHLEIERMACHER HERBERT
IPC: F04B37/14
Filed: 1981-01-17
Abstract: The invention relates to a vacuum pump and its arrangement for the supply of vacuum-operated motor vehicle elements, which is preferably fixed directly on the cylinder head laterally below the cylinder head cover and is driven by the overhead camshaft of the internal combustion engine by means of a tappet arranged in the working direction of the pump. The engine splash oil necessary for lubrication of the pump must be capable of running back into the engine even when the vehicle is in a tilted position. In a vacuum pump in accordance with this invention this is made possible in that an oil return from the cylinder head to the crankcasing is incorporated into the pump, which also undertakes lubrication of the pump.
Patent DE-3102838-A1 (DE)
Title: Compressed air cooling system for internal combustion engines
IPC: F02B75/02
Filed: 1981-01-29
Abstract: The invention relates to a cooling system for use in internal combustion engines, especially diesel engines, using compressed air as cooling medium and utilising the pressure rise in the cooling medium during heating in order to increase the engine power. The invention works on the following principle: the cylinders and cylinder head walls of an internal combustion engine are surrounded by an air-tight housing as cooling jacket. Compressed air is introduced into this as cooling medium. Due to the heating of this air after introduction into the cooling jacket the pressure is further increased. The cooling air under increased pressure is fed, controlled by a crankshaft, into the combustion chamber when the piston is in the end phase of the working stroke. An additional power-increasing force is thereby exerted on the piston. The cooling air may be precompressed either externally (compressor) or by the piston of the combustion chamber before it serves as cooling medium and its pressure is further increased in the process.

Patent DE-3103051-A1 (DE)
Title: Electro-thermal flowmeter
Inventor: BAIER PAUL WALTER PROF DR
IPC: G01F1/696
Filed: 1981-01-30
Abstract: If a PTC thermistor probe, which is supplied using an electrical voltage source, is located in a tube through which a medium flows at constant temperature, the supply current to the probe is a measure of the flow rate. If the medium temperature is not constant, this fact must be taken into account when determining the flow rate from the supply current. The object of the invention is to reduce the circuit complexity required for temperature compensation in comparison with a known method. The achievement of the object according to the invention is explained with reference to a drawing. A signal corresponding to the difference between the current in the PTC thermistor heating probe (1) and the current in an additional PTC thermistor (6) (which is supplied from the same voltage source as the PTC thermistor heating probe (1) and is in a region of the medium which is not flowing) is supplied to the counter input (21-22) of a divider (18) which displays a quotient. The denominator input (19-20) of the divider (18) receives a signal corresponding to the current in the additional PTC thermistor. The quotient displayed by the divider (18) is then a measure of the flow rate, which measure is independent of the medium temperature. <IMAGE>
Patent DE-3104265-A1 (DE)
Title: Electric cooker having a warning indication and an indication of residual heat in the cooking surfaces
Inventor: MCWILLIAMS JOSEPH ANTHONY
IPC: H05B3/74
Filed: 1981-02-07
Abstract: The subject of the invention is an electric cooker with respective optical indication when cooking surfaces exceed a temperature of 50 to 60 DEG C, the pilot or warning lamp being extinguished only when, in the cooling phase, the cooking surface or cooking surfaces have cooled to the said temperature. This is achieved in that the individual heating units are arranged on the underside of the top plate of the cooker in such a way that there is formed between the actual heating elements and the underside of the top plate a closed cavity having an orifice for connection to the environment of the heating unit, hot air escaping through the said connecting orifice when the unit is in operation. Mounted in the orifice or in its immediate vicinity is a thermal sensor which responds to the escaping hot air and which switches on an associated pilot lamp. The size and responsiveness of the temperature sensor and its placement are selected so that, when a temperature of 50 to 60 DEG C is reached on the surface of the top plate, the pilot lamp lights up in the region of the cooking zone and thus indicates that specific regions of the cooker have an increased temperature and constitute a source of danger.
Patent DE-3112750-A1 (DE)
Title: Sheeting plate for supporting trench walls
Inventor: CONRADS FRIEDRICH
IPC: E02D17/08
Filed: 1981-03-31
Abstract: Sheeting plate (1) for supporting trench walls, in which two welded plates of wedge-shaped design on the sides facing the trench bottom in each case are provided at a distance from one another and have on the surface facing the trench in each case at least one torsion-resistant cross piece (2) running perpendicularly to the trench wall. To support the plates against one another, in each case at least one bearing piece (8) connected to a spindle (7) is arranged on the cross piece (2). The cross pieces (2) are connected to the sheeting plates (1) in alignment in such a way that they have the same cross-section in the perpendicular direction as the hollow sections (3, 5) forming the sheeting plate (1). In the longitudinal direction of the trench, the cross pieces have a considerably smaller extent than the sheeting plate (1). Either the two perpendicular side faces of the plates are connected to one cross piece (2) each or one cross piece is inserted concentrically to the sheeting plate. This design ensures that a cross piece does not protrude into the trench interior, and the width of the trench to be excavated can thus be correspondingly reduced despite all requirements for adequate stability. <IMAGE>

Title: Arrangement for avoiding measurement errors in the frequency-selective measurement of signal levels
Inventor: SCHERENZEL HELMUT ING GRAD
IPC: G01R19/00
Filed: 1981-06-12
Abstract: The invention avoids line-dependent measurement errors in the frequency-selective level measurement at test outputs of carrier-frequency devices over long connecting lines between test output (1) and test instrument (6) (for example at the central carrier-frequency measuring station). The signal to be measured (Sfm) is modulated by a modulator (3) with the converter signal (Sfu) generated by an oscillator (64) of the test instrument (6) at the location of the test output (1) and converted into a constant-frequency intermediate-frequency signal (Sfz). The frequency of this intermediate-frequency signal (Sfz) is equal to the passband frequency of the intermediate-frequency amplifiers (61, 62) of the test instrument (6). Frequency-selective elements (4, 7 and 65) enable the converter signal (Sfu) and the intermediate-frequency signal (Sfz) to be transmitted on one and the same connecting line (5). The attenuation of the connecting line (5) only needs to be taken into consideration for this fixed intermediate frequency and, as a result, remains constant at all measuring frequencies. When coaxial selection switches are used for selecting different connecting lines, the switch only needs to exhibit the required characteristic impedance at the intermediate frequency and can thus be of relatively simple construction. <IMAGE>

Title: Handle with clamping device for tube-like sheath
Inventor: HOLLAND-LETZ HORST
IPC: B25G3/20
Filed: 1981-12-15
Abstract: The invention relates to the connection between a tube-like sheath and an inserted handle, preferably made of plastic. Similar known connections have a thread, or an O-ring on the inserted handle which serves as an adhesive friction element. These connections are relatively expensive, the threaded connection can become loose during work. The object is to provide an inexpensive but functionally reliable connection. This object is achieved in that the handle has, on the end face, axially parallel incisions, through which resilient, tongue-shaped segments are formed, which carry elevations on the circumferential surface. On inserting the handle into the tube-like sheath, the tongue-shaped segments are radially compressed via the elevations and act as clamping elements. In the drawing, Figure 1 and 2 show the handle (1) with the tongue-shaped segments (2) and the elevations (3) situated thereon, and also the end-face slots (4). <IMAGE>

Title: Process for the preparation of crosslinked polymers containing isocyanuric acid and oxazolidone rings
Inventor: ROTH WERNER DR RER NAT
IPC: H01B3/30
Filed: 1982-02-11
Abstract: The invention relates to a process for the preparation of crosslinked polymers which contain isocyanuric acid and oxazolidone rings and have high thermal stability and flame resistance and, in addition to the usual areas of application of plastics, can be employed as engineering materials and electroinsulating materials in electrical engineering. The processing of reaction-curable resin compositions comprising polyisocyanates, polyepoxides, tertiary amines and optionally additives and having very high reactivity at room temperature by conventional technologies with shaping and warming becomes possible through the addition, in order to inhibit the reaction at low temperatures, of organic electron acceptors which are stable under the processing and use conditions and do not impair the electrical properties of the polymers. This enables the use of the reaction-curable resin compositions based on polyisocyanate and polyepoxide in casting technology for the production of castings, for the impregnation of woven fabrics for the production of prepregs and laminates, as an impregnating resin in the construction of electrical machinery, as an adhesive resin, etc., it being possible to employ the products anywhere in electrical engineering, in particular where high demands are made of the thermal stability.
