Title: A method of producing an antenna system having main and auxiliary reflecting surfaces
IPC: H01Q15/14
Filed: 1989-06-07
Abstract: To produce a dual reflector antenna system capable of 
passing radiation to or from a shaped coverage area by means of 
a single feed (1), a three dimensional main reflector surface (3) 
and a three dimensional sub-reflector surface (2), a method is 
employed which includes defining desired levels and/or 
characteristics of radiation incident upon or received from 
selected regions of said coverage area, and optimising actual 
radiation levels and/or characteristics for said regions by 
modifying both said reflector surfaces (2,3) simultaneously.  
     The optimisation is achieved by iteratively determining 
levels and/or characteristics of radiation incident upon or 
received from each of said regions and obtaining the least 
favourable value of level and/or characteristic and modifying said 
reflector surfaces (2,3) simultaneously to obtain an improved 
least favourable value of level and/or characteristic.

Title: Partial oxidation of low heating value hazardous waste petroleum products
IPC: C10J3/46
Filed: 1989-10-10
Abstract: Low heating value liquid hydrocarbonaceous and/or solid 
carbonaceous hazardous waste materials from the production, 
refining and marketing of petroleum products are destroyed 
without contaminating the environment while simultaneously 
gaseous mixtures comprising H₂ + CO i.e. synthesis gas, 
reducing gas, or fuel gas are produced. From about 0.3 to 
2.0 wt. % of an anionic surface active dispersant and water 
(if needed) are mixed with the hazardous waste material to 
produce a first aqueous mixture. A comminuted solid 
carbonaceous fuel i.e. coal, petroleum coke is mixed with 
water and from about 0.02 to 1.00 wt. % of the dispersant to 
produce a second stable pumpable aqueous slurry. The first 
and second aqueous slurries are mixed together to produce a 
stable pumpable final blend aqueous slurry which is reacted 
in a partial oxidation gas generator as the feedstock. It 
was unexpectedly found that to achieve slurries with 
satisfactory rheological properties from mixtures of 
hazardous waste material and coal or coke slurries, it was 
necessary to add the dispersant to the coal/coke slurry as 
well as to the slurry of hazardous waste material before 
combining the two aqueous mixtures together.

Abstract: Die Erfindung bezieht sich auf ein Verfahren und eine Vorrichtung 
zum Ziehen von Rohrkörpern 3, insbesondere von rechteckigen Rohr­
körpern 3 mit bogenförmiger Achse 11, wie sie als Kokille zum 
Stranggießen von Stahl Verwendung finden. Bei der genannten sowie 
bei weiteren Anwendungen ist die Einhaltung vorgegebener Maße für 
die Wandstärke des Rohrkörpers 3 von großer Bedeutung. Der 
gradlinige Antrieb in Richtung auf eine Ziehform in Gestalt eines 
Druckringes 6 führt infolge der Krümmung des Rohrkörpers 3 zu einer 
exzentrischen Lage beim Durchgang durch den Druckring 6, so daß die 
Wandstärke normalerweise unterschiedlich ausfällt. Die Erfindung 
behebt dies dadurch, daß der Druckring 6 in Abhängigkeit seines Ab­
stand vom hinteren Dornende in eine Schrägstellung gesteuert wird, 
bei welcher er zentriert durch den Druckring 6 geführt ist, so daß 
die Wandstärke trotz unterschiedlicher Krafteinwirkung auf den 
Druckring 6 gleich gehalten werden kann. Eine Steuerfunktion kann 
für die Lage des Druckringes auf Grund empirischer Messungen des 
Abstandes des Dorns 2 während seiner Einschubbewegung vom Innenrand 
des Druckrings 6 ermittelt werden.

Title: Device for obtaining a load signal from a mechanically sprung and driven axle of running gear comprising a lift-axle
IPC: B62D61/12
Filed: 1990-04-30
Abstract: 2.1 The axle load of the mechanically sprung drive axle of running gear comprising a lift-axle can be described by the spring deflection of the suspension spring and the pressure of the lifting bellows. A previously described device has a signal body which can be displaced axially by the pressure and rotated by the spring deflection. A three-dimensional characteristic diagram is arranged on the signal body and determines for each constellation of rotational position and axial position the position of the one end of ram representing the axle load signal to be obtained. 2.2 In order to simplify the previously described device, the invention proposes the replacement of the three-dimensional characteristic by a two-dimensional contour (20, 21) and the arrangement in the slide (22, 24, 26) of a cylinder unit (24) which can be subjected to the pressure of lift bellows (1), which unit adjusts the slide length in a pressure-dependent manner. As a result, an adjustment of the position as a function of the slide length is superimposed on the adjustment of the position of the end (26) or the ram (22, 24, 26) by the contour (20,21). 2.3 The preferred area of application is vehicle technology. <IMAGE>

Patent EP-0547320-A3 (EP)
Title: Equipment for driving magnetic heads designed for recording data on a magnetic medium
IPC: G11B19/02
Filed: 1992-10-12
Abstract: The equipment comprises a power driver (PWR) which 
supplies the head (T), which in turn is supplied at a 
voltage (V) made proportional to the nominal voltage of 
the said head and which is provided with a sensor (Rs) 
which detects the magnetisation current of the head. This 
sensor is in turn connected to a control circuit (CNT) 
which drives the power stage (PWR) and which receives 
activation commands from the outside, these commands 
corresponding to the direction of flow of the current in 
the head. When the said sensor (Rs) detects that the 
magnetisation current of the head has reached the nominal 
value, it signals this event to the control unit (CNT) 
which proceeds to divide the flow of the said current by 
the opening and reclosing at suitable frequency of the 
switch or switches which in the power stage (PWR) cause 
the said current to flow in the direction determined by 
the external command in the said control unit, in such a 
way that the said current is kept at a substantially 
constant value. The cancellation of the magnetisation 
current, when its direction has to be changed, is very 
rapid as a result of the known design of the equipment of 
the bridge type with recirculation diodes.
