Inventor: RIEDL REINHOLD DIPL ING
IPC: B60B11/00
Filed: 1988-09-08
Abstract: In order to achieve adaptation of the twin wheels to unevenness in the ground or a certain amount of terrain running of these twin wheel sets even in the case of twin wheel sets of small construction for mobile lifting and setting-down devices for transportable large containers, the twin wheels are mounted by their hubs (28) on a hub carrier (24) which surrounds the wheel axle (19), attached rigidly to a wheel bow (14), with radial play. Furthermore, the hub carrier (24) is connected securely against rotation to the wheel axle (19) in its central region (21) and is arranged so as to be tiltable about a bearing pin (22) arranged transversely to the wheel axle (19). As a result, both twin wheels can in each case remain in ground contact, even in the case of unevenness in the ground or sloping ground, and jointly bear the load on the ground. <IMAGE>

Title: Method of controlling heading machines and apparatus for carrying out the method
Inventor: KETTERER KLAUS DIPL ING
IPC: E21D9/10
Filed: 1988-11-11
Abstract: The high temperatures occurring at the cutting picks and in the cutting tracks during the driving of roadways by means of selective-cut heading machines are prevented by sound bodies being allocated to the individual cutting picks. The sound bodies are in turn connected to frequency meters and a control unit for the motor. In a selective-cut heading machine designed in this way, the cutting-head speed can be adapted quickly and accurately to the respective rock strength. Optimisation of the cutting performance and a simultaneous reduction in the ignition risk are thereby achieved. <IMAGE>

Title: Device for the combustion in stages of a fuel/air mixture
Inventor: KOHLMANN HANS-ALBRECHT
IPC: F23C6/04
Filed: 1989-02-08
Abstract: A device for the combustion in stages of a fuel/air mixture comprises two combustion chambers (6 and 9) arranged in series in the direction of flow of the mixture. Each of these combustion chambers (6 and 9) is assigned a heat exchanger (7 and 10, respectively), the heat exchanger in the first combustion chamber (6) serving primarily to cool the combustion chamber and reduce the combustion temperature and that in the second combustion chamber serving to heat a medium to be heated. The reduction in the temperature of the first combustion process prevents the thermally induced formation of NO. The mixture (11) flowing to the second combustion chamber (9), which is composed of as yet unburnt mixture and the exhaust gases from the first combustion chamber (6), can have additional combustion air (12) added to it in order to fully oxidise this mixture in the second combustion chamber (9) and minimise the proportion of pollutants in the exhaust gases (16) from the second combustion. <IMAGE>

Title: Device for measuring and transmitting pressure and temperature values in the area subject/not subject to explosion hazards
Inventor: STIRNBERG DIETER DR ING
IPC: G08C23/06
Filed: 1989-03-04
Abstract: For transmitting data out of areas which are subject to explosion hazards the required energy is supplied by a battery integrated in the housing so that in the area which is not subject to explosion hazards power-supply units are not required. It is also not necessary to transport the required energy in any way from the area which is not subject to explosion hazards into the area which is subject to explosion hazards. Capacitive sensors or contacts and the evaluation electronics and the parts transmitting the optical pulse sequences are supplied by the battery. They operate discontinuously so that the battery is loaded to a very limited extent. In the evaluation electronics the data are converted into optical pulse sequences and fed per se via the optical transmitter or similarly suitable parts to the receiving device arranged in the area which is not subject to explosion hazards and there converted again into electrical digital data. The assessment can take place by means of a computer which accommodates the receiving device. <IMAGE>

Title: Method for protecting a gate turn-off thyristor against short circuit
Inventor: EGGERT BERNHARD DR ING
IPC: H03K17/082
Filed: 1989-04-06
Abstract: A method for protecting a gate turn-off thyristor (1), which switches a load, against short circuit during its turning-off process is to be specified which protects the GTO thyristor (1) against destruction. For this purpose, it is determined whether the rise (diA/dt) of the anode current (ia) of the GTO thyristor (1) is greater than the greatest possible current rise (diLM/dt) caused by the load during operation. It is also determined whether the rise (digdt) of the negative gate current is negative (ig < 0). When both criteria hold true at the same time, the turn-off process of the GTO thyristor (1) is immediately interrupted and, instead, the GTO thyristor (1) is immediately retriggered by a positive gate current. <IMAGE>

Patent DE-3931589-A1 (DE)
Inventor: MICHEL HARTMUT DIPL ING
IPC: F02P7/03
Filed: 1989-09-22
Abstract: The invention relates to a semiconductor component of a first n<+>-doped layer (1), a second p-doped layer (2), a third n<->-doped layer (3) and a fourth p-doped layer (4). Layer (1) forms a cathode emitter and layer (4) forms an anode with suitable metal coatings (6 and 7). According to the invention, the semiconductor component triggers a flip-flop cycle since two central layers (second layer 2 and third layer 3) are given such a thickness and doping that the space charge region on the application of a voltage to the component extends towards the next pn junction (between the third and fourth layers 3 and 4 and/or the first and second layers (1 and 2) in such a way that the corresponding current amplification alpha (alphapnp and/or alphanpn) increases. Alternatively, the flip-flop cycle may also be triggered when the space charge region reaches the next pn junction. The component of the invention exhibits small variations in the parameters UBO and IH especially if n-doped Si material (rho = 100 ohm.cm or more) is used for the central layer (3). The parameters UBO, IBO and IH may be adjusted largely independently with the component of the invention. With the components it is possible to make series circuits of many components and in particular it is possible to produce component stacks for very high voltages which are especially suitable as fast, passive high-voltage switches to steepen the high-voltage pulses in the secondary circuit of an ignition system.

Title: Variation of tyre tread pattern to suit road conditions
Inventor: LIEBIG WILLI
IPC: B60C11/16
Filed: 1989-12-28
Abstract: A process is described which allows the tyre tread pattern to be varied according to the varying road conditions, esp. wet or icy surfaces. The negative effects of dirt and icing on the tyre are avoided and the changeover time is minimal. The main feature of the process is the ability to distribute the tractive effort over different parts of the tyre tread by using tyre pressure. A tyre can be adapted to icy road conditions by controlling the pressure inside a chamber in the tread area and below an area of special studs. The special chamber can be activated: (1) with the vehicle stationary or moving; (ii) rapidly; (iii) by manual or automatic controls, e.g. via sensors and wireless transmission of sensor pulses, are delivered through receivers and pulse guides to ignite gas cartridges.  An alternative method of activation uses compressed air in containers in the wheel and controlled by valves and lines. Control units facilitate the readaptation to changes in road conditions.
