Title: Method for monitoring technical systems
Inventor: RUBBEL FRANK-EGBERT DIPL ING
IPC: G01D7/06
Filed: 1981-03-23
Abstract: For monitoring technical systems by using computers, it is known to use display devices in order to display power or mass flows. According to the invention, the measurement values of the currents are displayed in normalised form on scales (1 to 4) which have the same length for a number of measuring locations and extend parallel to one another at a distance. The instantaneous values are then connected by straight lines (7a, 7b, 7c) extending from measurement point to measurement point, which lines extend at right angles to the scales in normal operation whilst a fault case results in an inclined position (7c) which immediately draws attention to itself. <IMAGE>

Title: Pump combination with flow rate control device
Inventor: SCHOPF WALTER
IPC: F04C2/14
Filed: 1981-09-17
Abstract: Pump combination with flow rate control device for the pressure medium supply of hydraulic systems having different rotational drive speeds, preferably for mobile drives. Conventionally, the oil pump design must be able to cope with the lowest operational rotational speeds. In high rotational-speed ranges, however, unnecessarily high deliveries and losses arise, and moreover, in the case of wide delivery ranges, the functional and operating quality of servo devices, control devices and regulating devices suffers. The main purpose and advantages of the present pump combination are an evening-out of the output or appropriate adjustment of the output while saving drive energy, with a number of advantageous functional features tailored to the use in motor vehicles. The main constructional feature and function consists in a plurality of pumps or one pump (pos. 1) being combined with a plurality of pump stages having hydraulic regulating or control devices (3, 5, 7, 53, 54) into one assembly and being connected in such a way that individual pump stages are connected in with, or disconnected from, the useful delivery stream, controlled as a function of the pressure or (usually) the useful output or externally. In the first case they deliver, at low capacity, into a base having a low pressure level (2, 72). An advantage compared to variable-delivery pumps is the possibility of using the low-pressure and low-loss (switched-off) delivery streams economically for lubricating and cooling purposes. <IMAGE>

Patent DE-3203880-A1 (DE)
Title: Tyre pressure indicator
Inventor: AGUGLIA GIANLUIGI
IPC: B60C23/02
Filed: 1982-02-05
Abstract: Tyre pressure indicator for indicating the pressure in a tyre, mounted on a vehicle wheel, irrespective of whether the wheel is stationary or rotating, having a passive resonator which is composed of a first coil, a capacitor which is attached in the tyre and a second coil which is attached in the wheel rim coaxially with respect to the wheel, said components being connected one behind the other, and having a pressure-sensitive element which is attached in the tyre and in the case of pressure changes acts on a ferrite rod in order to displace the latter and thus change the inductance of the first coil. An oscillator is connected to the vehicle frame and has a third coil which is magnetically coupled to the second coil and is set to the same frequency as the passive resonator when the tyre pressure has the expected value. In this state, the passive resonator absorbs energy from the third coil and thus damps the oscillator. In the case of a change in the tyre pressure, thanks to the magnetic coupling the oscillator supplies an output signal which is then amplified and rectified and permits an indication of the pressure. <IMAGE>

Title: Process and device for the positioning of articles and their transfer in an aligned position
Inventor: KOENIG RAINER
IPC: B65G47/248
Filed: 1982-04-20
Abstract: So that articles delivered in succession on a conveyor path can be simply and cost-effectively positioned in a predetermined aligned position and transferred, irrespective of their formation and dimension, quickly and reliably at the highest possible rotational and pivoting speeds, in such a way that the risk of self-damage and self-destruction of sensitive articles is avoided and any arrangement and handling of the articles in space is possible during the entire positioning operation, according to the process the articles are rotated about a pivot axis, parallel to the conveying direction, downstream on the conveyor path from the location of determination of their delivery position, if there is any deviation from their predetermined aligned position. The articles can also be simultaneously rotated about a pivot axis, parallel to the conveying direction and perpendicular to the conveying direction, downstream on the conveyor path from the location of determination of their delivery position over a specific length of the conveyor path, if there is any deviation of their delivery position from their predetermined aligned position in relation to the position of a face of these perpendicular to the conveying direction.

Title: Pan provided with a lid, for cooking and grilling
Inventor: SCHAWALDER ALBERT C
IPC: A47J37/01
Filed: 1982-07-07
Abstract: A pan has a bottom which rises from the outside towards the centre and has in the central region an opening drawn up in the manner of a chimney. The associated lid bears on its inner side a baffle plate, which in the position for use is located above the opening drawn up in the manner of a chimney. This baffle plate has the effect that the air greatly heated between cooking plate and bottom of the pan and flowing into the pan through the opening drawn up in the manner of a chimney is deflected downwards in the direction of the upper side of the item being cooked. The baffle plate is expediently curved and faces the said opening with its concave side. This has the effect of accomplishing a more even heating of the item being cooked or grilled, for example chicken legs, located in the pan. The bottom area has a plurality of beads running around and protruding in the direction of the interior of the pan, on which beads rests the item being grilled, to be warmed, while the fat collects in the outer, lower-lying edge zone.
