Patent DE-3026224-A1 (DE)
Title: Control method for flight of contour hugging aircraft - using radar scanning and having data store for comparison of profile of land sections
Inventor: FEIL GEORG DIPL ING
IPC: G05D1/06
Filed: 1980-07-10
Abstract: Enemy transmitters are able to 'blind' the receivers of low flying aircraft and force them to increase altitude immediately thus rendering them open to detection. To overcome this, the aircraft radar system which is used to scan the land contours and control the on-board computer can be adapted so that the land profiles are retained in a data store that compares the last immediate measured land profile with the directly preceding one. If the results of the computed comparison show that the contour sections agree with one another, no action is necessary as it can be concluded that the analysis is correct. However, if clear deviations appear in the last measured contour compared with that previously stored, faulty functioning of the radar or external counter measures may be the cause. In this event, the last measured contour is rejected for controlling the aircraft, and the previously stored one taken to represent the real contour. Thus the contours of the land are continuously compared in the data store throughout the flight.

Title: Sorption medium removing contaminant gases from furnace fumes - is circulated to alter grain structure before return
Inventor: HELLMICH FRIEDRICH
IPC: B01D53/50
Filed: 1980-11-07
Abstract: Sorption medium used for extn. of environmentally harmful gases from fumes, esp. from tunnel kilns, has its granular structure altered during transit through a separate circuit, including a grinder, before being returned to the incoming fume conduit before a cyclone mixer, normally in close conjunction with supplies of fresh medium. The appts. includes a blower which sucks sorbent material through an adjustable dip pipe from the body of material accumulated in a base container on falling from the set of upper filter bags when forced away by a compressed flushing air supply. This removed material is returned to the fume conduit, pref. via a grinder mill. The sorption medium is normally particles of lime (slaked or quick). Used for removing SO2, HF, nitrogen oxides and other gases harmful to animal and vegetable life, in the fumes from furnaces fired by coke, coal, oil, tar products in the brick and ceramic industries, glass, aluminium and fertiliser plants etc. Constant resurfacing of the lime etc. particles through grinding makes their utilisation more complete, hence more effective and cheaper.

Title: Synthesiser type tuning voltage generator - uses pulse signal, having width corresponding to frequency, received by voltage converter and low pass filter
Inventor: FUJIMOTO ISAO
IPC: H03J5/24
Filed: 1980-12-11
Abstract: The tuning voltage (e.g. for a variable capacitance tuner) is produced from an input pulse signal having a pulse width corresponding to a frequency to be received by a voltage converter (T411) and a low-pass filter (43). In order to define accurately a limit to the tuning range a reference voltage, applied to the voltage converter (T411) is generated by dividing (R441,R442,R443) a voltage stabilised by a constant voltage diode (444) using resistors. The resistor voltage divider circuit determines the upper limit of the tuning voltage obtained from the low-pass filter. Two kinds of reference voltages having different levels may be generated as a reference voltage and switched associated with band switching. The appts. also comprises a lower limit determining device, for the tuning voltage from the low-pass filter (43).

Patent DE-3110692-A1 (DE)
Title: Arrangement for maintaining distances between track-bound vehicles
Inventor: KRAUS PETER DIPL ING
IPC: B61L23/14
Filed: 1981-03-19
Abstract: The invention relates to an arrangement for automatically maintaining distances between vehicles (1.0, 1.1, 1.2, etc.) which are equipped with transmitters (4) and receivers (5) and which follow one another along a vehicle track which is divided up into route sections (in terms of safety technology). Here, the maintenance (of the vehicle sequence) takes place by means of a travel-enabling signal which is transmitted from one stationary transmitter (8) of the end, lying ahead in the direction travel (3), of the respective route section to the vehicles via a slotted hollow conductor (6) which is coupled to the vehicle transmitters and receivers (4 and 5, respectively) and extends along the vehicle track, in such a way that the signal which propagates counter to the direction of travel and is received by the vehicle (1.0) which is located ahead in each case in the route section is passively suppressed in the wider propagation along the slotted hollow conductor by this vehicle and, at the same time actively regenerated, is fed again into the slotted hollow conductor (6) to be passed on to the respectively following vehicle (1.1). In order to be able to reliably distinguish with this safety system in a single track section all the vehicles which are endangering the maintenance of the vehicle sequence from the other (intact) vehicles, according to the invention the stationary transmitter (8) is assigned a second slotted hollow conductor (9) which has the same degree of damping and is arranged parallel to the first slotted hollow conductor (6), per vehicle (1.0, 1.1, 1.2) there being a coupling to this second slotted hollow conductor (9) produced on the receiver side only; in addition, a device which compares, in an individual vehicle, the received travel-enabling signal with the reference signal received by means of the second slotted hollow conductor (9) triggers braking of the vehicle when there is a difference in size between the two signals. <IMAGE>

Title: Device for the uneven attachment of the blanket to the cylinder of an offset printing machine
Inventor: LIEBERT OSKAR
IPC: B41F27/12
Filed: 1981-04-10
Abstract: The rotatable blanket attachment spindle (1), having clamping devices for fixing the end of the blanket, has a smaller diameter in the central region (A) than at the edge regions (B, C). By means of this concave design of the blanket attachment spindle (1), seen in the axial direction, it is achieved that, when the blanket is attached to the cylinder (2) of an offset printing machine, said blanket is stretched by a greater amount at the edge regions (B, C) than in the central region (A), as a result of which its thickness at these edge regions (B, C) is less than in the centre (A). As a result, compensation of the cylinder deflection is possible, so that the linear pressure between the rubber-covered cylinder (2) and a material to be printed is approximately equal over the entire region.   <IMAGE>
