Title: Fettling and machining of cast parts - where casts are in automated finishing line with fettling and precision machining stations
Inventor: MUELLER JOHANN DIPL ING
IPC: B22D31/00
Filed: 1992-11-02
Abstract: In the fettling and machining of cast parts by fettling (removing risers, grinding seams, flash removal, etc.) pref. with one-tenth mm. precision and then machining (milling, drilling, sinking, turning and then deburring) pref. with micron precision, the improvement is that the cast parts are processed, in an automated finishing line in the foundry, by (i) conveying to one or more parallel operating fettling stations, transferring to transport holders and fettling pref. using several fettling tools at several locations; (ii) immediately conveying the cast parts from the last fettling location to a directly adjacent machining stationl and (iii) holding the cast parts in a precision clamping device and carrying out machining with precision tool arrangements which are precisely aligned relative to the clamping device. Also claimed is a plant for carrying out the above process. ADVANTAGE - The process provides rapid, reliable and flexible, automated and mechanised, complete processing of metal castings (sand, permanent mould and pressure die castings) of various sizes and shapes and in various quantities, at reduced finishing costs and fixed and variable overhead costs.

Title: Intrusion alarm system, e.g. for mounting on window
Inventor: SIEGWARTH MARTIN DIPL ING
IPC: G08B13/04
Filed: 1993-01-08
Abstract: The alarm system includes an alarm sensor (1) as part of an oscillator circuit (4). The alarm sensor changes the resonance frequency of the oscillator to cause an alarm signal to be emitted. The oscillator on the sensor side is connected to a transmitter-side oscillator (5) and excites the latter. When there is no alarm, the two oscillators have the same resonance frequency. When there is an alarm, the load on the transmitter side oscillator is changed. The alarm-side oscillator includes a capacitor (3) and induction coil (2) connected in series.

Title: Irreversible thermo-acoustic engine
Inventor: CHRISTOV MARIN ANDREEV
IPC: F25B9/14
Filed: 1993-02-03
Abstract: An irreversible thermo-acoustic engine has a sound source (1) at one end of a resonator pipe (3) and another (2) at the other end.

Patent DE-4303838-A1 (DE)
Inventor: DUMMERSDORF HANS-ULRICH DIPL I
IPC: B01J19/30
Filed: 1993-02-10
Abstract: In mass transfer columns, in particular in distillation and extraction columns, fluidized-bed contacting elements (solids) are frequently used to improve the mass transfer. A considerable increase in the mass transfer rate can be achieved if asymmetrically shaped fluidized-bed contacting elements (E) are used which are characterised in that their geometric centre (M) does not coincide with the centre of gravity (S), the geometric centre (M) being defined as the intersection of the body diagonals of the smallest possible parallelepiped (Q) completely enclosing the fluid element. Typical examples of such shapes are egg-shaped or drop-shaped bodies. By means of such fluidized-bed contacting elements, in addition to improving the mass transfer, a reduction of the specific pressure drop can also be achieved. <IMAGE>

Patent DE-4327835-A1 (DE)
Title: Electrical machine, in particular an electric motor for driving fuel pumps
Inventor: REISNER KARL-HEINZ
IPC: H01R39/27
Filed: 1993-08-19
Abstract: In the case of electric motors which are immersed in an electrolytically acting medium, corrosion easily occurs in the components, particularly if these parts contain copper or copper alloys and interact with a steel part. Such material pairing also occurs in the case of the brush springs and the sliding brushes. In order to prevent corrosion in the case of these parts, according to the invention, at least one of the contact surfaces has an insulation layer (21), which is resistant to fuel and alcohol, between the brush spring (9) and that end surface (19) of the sliding brush (5) which faces away from the commutator (1). <IMAGE>
Patent DE-4332138-A1 (DE)
Title: Method for extending the life of chemical sensors
Inventor: MORITZ WERNER DR SC NAT
IPC: G01N27/38
Filed: 1993-09-17
Abstract: The method is described for extending the life of chemical sensors for determining individual components in the gas phase, the contact between fluoride-ion conductor and metal electrode being heated once or repeatedly under the conditions of the gas to be measured briefly to temperatures between 300 and 600 DEG C. Heating may be carried out by electrical resistance heating, the metal electrode being itself used as the heating resistor. With the method according to the invention, simple activation of the sensor under measuring conditions is made possible. By repeated activation, a significant increase in the life is achieved. The extremely short time of the reactivation has the effect that only the sensitive boundary surface is heated, whereas the sensor overall is heated only slightly, so that it is again at the measuring temperature directly after activation. The field of application is chemical analysis, for example environmental protection or process control.

Title: Process for the partial colour coating of articles
Inventor: ALBAT BERNHARD
IPC: B05B12/24
Filed: 1993-10-07
Abstract: The invention relates to a process for the partial colour coating of articles made from materials having ferromagnetic properties, in which parts of the surface of the articles or orifices to spaces in the articles which are not to be provided with a colour coat, or not in the intended coating operation, are covered or closed before the coating operation. What is to be provided is a process by which a covering of faces or a closing of spaces to articles having ferromagnetic properties can be achieved at a reduced outlay in terms of labour and production. This object is achieved, according to the invention, in that permanent-magnetic foils are preformed according to the form of the faces or orifices to be covered, are subsequently laid onto the faces or orifices and are attracted by a magnetic force so as to cover the surface sealingly.

Title: Recognition of crank-shaft phase relation in IC engine
Inventor: DENZ HELMUT DIPL ING
IPC: F02D41/34
Filed: 1994-05-27
Abstract: The crankshaft of an IC engine has a segmented disc with a sensor measuring its angular position. An evaluator deduces the speed from the sensor signals and releases firing and/or fuel injection pulses depending on the angular position. Recognition of the crankshaft "phase" position is given by comparison of segment times, inside which the crankshaft rotates by a given angle. The angles when injection occurs are chosen according to certain conditions so that speed changes occur, allowing clear recognition of the phase. The phase recognition takes place at the end of a thrust phase and the sequential fuel injection takes place by stepped resubstitutions.

Patent DE-4428564-A1 (DE)
Title: Method for manufacturing bent hollow parts
Inventor: BONNY PIERRE DIPL ING
IPC: B21D26/02
Filed: 1994-08-12
Abstract: The method uses internal high pressure deformation (IHD) process where a straight pipe is roughly preformed in a two-part IHD tool and then finished formed by applying high internal pressure to both ends of the blank after the tool is closed. Bending occurs pref. in a plane parallel to the movement of the IHD tool and the pressure connectors (15), swivelling indirectly about pivots (11). The bending machine comprises a two-part IHD tool (4) fitted in a press and internally contoured to the shape of the finished part and axially movable plunge connectors for the ends of the pipe blanks which are carried in swivelling hydraulic cylinders (9) which supply the high pressure fluid for the IHD process. The blank is lightly pressurised before the preforming operation, the final pressure being in the plastic range of the material. The bending occurs in the plane of the hydraulic connectors (15), which swivel to accommodate the movement of the ends of the pipe. No forces act on the workpiece other than the weight of the connectors and forces arising from the inertia of the hydraulic cylinders (9). The cylinders (9) swivel about pivots (11) and are rotated to a drive (17), a hydraulic cylinder, to follow the movement of the connectors independently. The drive (17) also acts as a counterbalance between cylinder (9) and connector (15) at the start of the work cycle.
