Patent EP-0185649-A3 (EP)
IPC: C10J3/82
Filed: 1985-12-13
Abstract: Die Erfindung betrifft ein Verfahren zur Erzeugung von 
überhitztem Vergasungsrohgas. Durch den Stand der Tech­
nik ist bekannt, daß durch Überhitzung von durch Gegen­
stromvergasung in Festbettvergasungsreaktoren erzeugtem 
Vergasungsrohgas eine Kondensation im Gas enthaltener 
flüssiger Bestandteile, insbesondere Teer und andere flüs­
sige Kohlenwasserstoffe, vermieden und damit ein abpro­
duktfreier Transport oder eine trockene Entstaubung des 
Vergasungsrohgases gesichert werden kann, wobei zur 
Überhitzung des Rohgases ein Zusatzbrennstoff oder die 
Verbrennung eines Teilstromes des erzeugten Vergasung­
srohgases verwendet wird.  
     Erfindungsgemäß wird das verhindert, indem ein Teil­
strom über eine Umgehungseitung (2) des in der Hochtem­
peraturzone (4) der Vergasungszone entstehenden Verga­
sungsgases nicht zur Schwelung des Brennstoffes in der 
Schwelzone (3) eingesetzt sondern ohne bedeutende Wär­
meabgabe durch oder um die Schwelzone (3) des Verga­
sungsprozesses gefahren und dem aus der Brennstoffschüt­
tung über der Schwel- und Trockenzone austretenden 
Gemisch aus Schwel- und Vergasungsgas zugemischt wird.

Title: Drill coulter for a seed drill
IPC: A01C5/06
Filed: 1986-10-01
Abstract: The drill coulter for a seed drill has a proportioning device which precedes the coulter and by means of which seed can be fed from a seed stock to a seed guide channel passing through the coulter from the top downwards. A coulter housing contains the seed guide channel and is fastened to the seed drill by means of a holding arm. From its lower end portion projects an essentially plate-shaped furrow-cutting body extending in the longitudinal vertical plane of symmetry and penetrating into the soil during sowing. The furrow-cutting body is designed as a cutting blade with relatively small essentially constant thickness (es) the front cutting edge of which is at an angle (o) to the horizontal. At least on one side of the cutting blade projects a lifting coulter which extends perpendicularly to the respective side of the cutting blade and the rear end portion of which is higher than its front end portion. <IMAGE>

Title: Magnetic tape cassette
IPC: G11B23/087
Filed: 1987-10-16
Abstract: A magnetic tape cassette has an improved reel 
spring (16), slack limiter and tape guide. The reel spring (16) has a 
generally rectangular shape with first and second parallel 
edges extending substantially along its entire length. A 
flat, central base portion of the spring is bounded by a pair

Title: Apparatus for rotatingly conveying preforms through a heating station to a stretch blow-moulding machine
IPC: B29C49/68
Filed: 1988-07-14
Abstract: An apparatus is provided for the conveyance of preforms through a heating station to a stretching and blowing machine during the production of hollow articles from thermoplastic plastics materials, means of which preforms having different neck diameters can be heated satisfactorily and extremely uniformly without major modification of the apparatus.

The preforms are collected and retained in position by the pick-up means as they pass through the heating station. The mutual spacing of the belts and, hence, of the pick-up means from one another and from the heating devices is adjustable. A further pair of endless drive belts are provided which rotate the preforms at desired circumferential speed about their own axes as they pass through the heating device so as to promote an even distribution of the heat in the preforms.
Patent EP-0304970-A3 (EP)
Title: Heat exchanger apparatus for cooling an object
IPC: A61B5/00
Filed: 1984-03-27
Abstract: A heat exchanger (31) cools at a programmed rate a prede­
termined area of skin. The rate at which the area of skin 
changes in response to temperature change of the heat 
exchanger and the rate the skin temperature returns to normal 
are then measured and compared to standard rates over a number 
of cycles. Impaired peripheral blood flow is evident espe­
cially on subsequent cycles as vascular disease slows the rate 
of return to normal temperature of the skin. The heat 
exchanger has a cooling chamber (110) with one side of the 
chamber being a cooling surface (111) adjacent the skin. An 
injector (130) is connected to a source of fluid (75) having a 
boiling point at ambient pressure less than the temperature to 
which the skin is to be cooled. The injector injects fluid 
into the chamber and onto the side of the cooling surface 
opposite the skin to boil the fluid on the surface to cool the 
surface and the skin.

through the lubricant fitting to be discharged from the 
adjuster housing, when a predetermined system lubricant 
pressure is attained. A compressible device (143) is 
contained within the actuator housing (54) to 
compensate for effective volume variations and 
precluding the exhaust of lubricant and the 
introduction of air during such changes.

Title: Method of fabricating sheet metal parts and the like
IPC: B23Q41/08
Filed: 1989-07-26
Abstract: A method and apparatus for fabricating sheet metal parts 
using workpiece manipulators to transfer a workpiece from 
one work station to another and position the workpiece for 
each operation to be performed. The invention eliminates 
the need of individual operators and can be managed under 
microprocessor control using known positions along 
selected X and Y axes about which programming is 
performed. A unified design and manufacturing system 
includes a computer-aided design (CAD) system and a 
microprocessor-controlled fabrication system consisting of 
a plurality of manufacturing stations which perform 
manufacturing and transporting operations upon a 
workpiece. Design information for a part is entered 
through the CAD system and includes a reference point. 
The design information is combined with manufacturing 
process planning information to produce a part definition 
data file which is used by the microprocessor-controlled 
fabrication system to perform machine operations upon a 
workpiece to produce the part according to the design 
information. In the microprocessor-controlled fabrication 
system, the reference point, as entered in the CAD system, 
is associated with a specific point upon the workpiece. 
During all times, the manufacturing stations maintain a 
known orientation between the specified location on the 
workpiece and axes of the microprocessor-controlled 
fabrication system.
Patent EP-0364699-A3 (EP)
Title: Method for sealed dosing, and boring arrangement
IPC: F16L55/128
Filed: 1989-08-24
Abstract: A method for sealing holes, involves fitting an essentially bushing- and/or tube-shaped plug into a hole and then the wall of the plug is expanded radially along at least one axial segment. In this method, the plug is positively anchored axially in the hole. By this method of producing an axially positive anchoring of the plug in the hole, not only is a tight fit of the plug in the hole achieved, but a mechanical movement of the plug relative to the hole is reliably prevented. A hole arrangement is tightly sealed with an essentially bushing- or tube-shaped plug in the hole having a radially spread axial part fitting tightly in the hole. Between the hole and the plug a locking arrangement with axially positive effect is provided. In a hole arrangement of this kind, not only is tightness ensured, but also piston-like displacement of the plug in the hole is prevented. The hole arrangement can preferably be so designed that the sealing and locking parts are provided axially at different points.
