Patent EP-0274754-A3 (EP)
IPC: C08J5/04
Filed: 1987-12-30
Abstract: A process to form a fiber-reinforced composite having a 
continuous thermoplastic matrix of poly(arylene sulfide ketone) resins is 
provided. The composite is useful to form shaped articles with high 
temperature resistance. The composite can be prepared by consolidating 
under heating a multi-layer stack of resin sheets and fiber reinforcement 
sheets. The poly(arylene sulfide ketone) resins can be melt-stabilized 
through treatment with a water-soluble salt of an alkaline earth metal. 
The composite has excellent thermal properties such as heat distortion 
temperature.
Patent EP-0250351-A3 (EP)
IPC: C08G18/63
Filed: 1987-06-03
Abstract: A process based on a polymerization reaction of an 
ethylenically unsaturated monomeric compound in a hydrox­
ylated polyester resulting from a polyesterification re­
action of a polycarboxylic acid or a derivative thereof, 
with polyhydroxylated compounds containing from 0.001 to 
0.5 mole % of an unsaturated monomer over the total of 
acid monomers comprising it; the amount of monomeric com­
pounds ranges from 5% to 40% by weight of the reactants.
Patent EP-0275079-A3 (EP)
IPC: H03F3/45
Filed: 1988-01-12
Abstract: A wide-band and high-gain differential amplifier 
adapted to amplify transmitted optical signals of the 
GHz band is constituted by GaAs MESFET's.  
     Two MESFET's (Q1, Q2) are differentially connected 
to each other. Drains of the MESFET's (Q1, Q2) are 
connected to load resistance (R L ) via a source-drain 
path of other MESFET's (Q3, Q4) whose gates are grounded 
in AC-wise.  
     Current by-passing means (4) are connected to the 
sources of the other MESFET's (Q3, Q4). DC bias currents 
of the differential pair of MESFET's (Q1, Q2) are set to 
relatively large values to increase the mutual conduc­
tance gm of the differential pair of MESFET's (Q1, Q2). 
Despite a large DC bias current, the current-by-passing 
means (4) decrease the DC voltage drops across the load 
resistance (R L ), and enable the differential amplifier 
to operate on a low power source voltage.

Title: Continuous process for eliminating unstable components from raw oxymethylene copolymers
IPC: C08G2/28
Filed: 1988-02-04
Abstract: A continuous process for removing unstable components from crude oxymethylene copolymers still containing catalysts, monomeric starting materials and unstable components, by treating the copolymers with deactivators, optionally in the presence of assistants, in a pressure zone and subsequently removing volatile components in a decompression zone, optionally in the presence of stabilisers, where the crude polymers are fully melted in the absence of deactivators and assistants immediately after completion of the polymerisation step, and the deactivators, either alone or together with assistants, are subsequently incorporated into the resultant polymer melt under pressure in at least one pressure zone. 
<??>This process avoids degradation and gives significantly better properties.

Patent EP-0298415-A3 (EP)
IPC: F23N5/20
Filed: 1988-07-05
Abstract: The present invention relates to a method for thermostatic 
control of a temperature modifying apparatus such as a 
heating unit or an air conditioning unit. This method 
involves measuring the ambient temperature, generating an 
error signal based upon the difference between a set point 
temperature and the measured ambient temperature, operating 
the temperature modifying apparatus according to the error 
signal, and adjusting the set point temperature based upon 
the time history of the error signal. In accordance with 
the preferred embodiment of the present invention, the 
temperature modifying apparatus is operated during the next 
cycle interval with a duty cycle proportional to the error 
signal at the start of the cycle interval. In the preferred 
embodiment the set point is adjusted via an adjustment 
quantity which is increased if the new duty cycle factor is 
greater than the previous duty cycle factor, decreased if 
the new duty cycle factor is less than the previous duty 
cycle factor and maintained unchanged if the new duty cycle 
factor equals the previous duty cycle factor, with the 
adjustment quantity maintained within a predetermined band.

Title: Electrically operated fluid valve
IPC: F16F9/46
Filed: 1988-07-25
Abstract: A piloted valve especially for manually switching 
hydraulic vehicle suspension units between hard and soft 
modes, and providing a third mode for very bumpy terrain.  
     A volume 8 (which may extend around the armature 9, 
10), gradually fills up through a low-flow path 7A, to exert 
a downward pressure on a first flap 6.  
     A pilot channel 16 is opened by energising coil 12, 
whereon an armature in two parts 9 and 10 closes up, lifting 
conical needle 8. The first flap 6 then rises through fluid 
pressure acting from below, because the downward pressure is 
released through the pilot channel 16. This is the soft 
suspension mode, because import port 3 from the unit connects 
with output port 21 and a reservoir, via the now uncovered 
seat 18. The hard suspension mode exists when the valve is 
effectively closed.  
     The ultra-soft or emergency mode is set up by the 
vehicle wheel hitting bumps, or other high pressure shocks, 
when the soft suspension mode is already in existence. 
Sudden shocks or high pressure P1 at the input port 3 then 
increases pressure P3 directly via uncovered seat 18, and 
this pushes down final flap 22 against an initial high bias 
exerted by six radial springs 25 against an inclined annular 
surface 27.  
     A bypass path through 23 is then opened. 
The final flap has a hole 29 by which fluid passes in 
the soft suspension mode. But bypass path 23 is even faster, 
and the "shock" moade is therefore very soft.

Abstract: Insbesondere bei Kraftfahrzeugen werden Schalter mit 
einem Metallgehäuse und einem Sockel aus Kunststoff als 
Rückfahrschalter, Getriebeschalter, Temperaturschalter 
oder dergleichen eingesetzt. Der Zink-Druckguß, aus dem 
das Schaltergehäuse üblicherweise besteht, gibt jedoch

eine endseitige Umfangslippe in dem Druckgußgehäuse ge­
sicherte glatte zylindrische Kunststoffsockel sich aus 
seiner Befestigung an dem Druckgußgehäuse lösen kann. 
Dies wird gemäß der Erfindung in besonders einfacher 
Weise dadurch vermieden, daß der Sockel (2) des Schalters 
(1) einen nach außen hervorstehenden Halteflansch (7) 
aufweist, daß die Umfangslippe (6) an einer vom Sockel 
(2) nach außen gerichteten schrägen Fläche (10) des

Abstract: In order to be able to forge round and sharp-edged bars down to very small dimensions without a tool change on a longitudinal forging machine, pivotable guide levers 18 for guiding rams 9 bearing tools 10 to 13 are provided with additional tools 14 to 17 which can be actuated in common with the tools 10 to 13 on the rams when the guide levers 18 are freely movable and the rams 9 are positively locked within the guide levers. When the guide levers 18 are fixed on the machine frame 6 and the rams 9 are guided in a straight line, previously round rough-forged material can be given sharp edges in a finish-forging operation, the mutually opposite pairs of tools 10, 12 and 11, 13 on the rams acting like two hammer-forging presses arranged in different vertical planes.

Title: Method and apparatus for controlling a wax-moulding plant
IPC: B29C67/24
Filed: 1989-10-11
Abstract: In a wax-moulding plant with a vacuum wax injector, the operating parameters (wax-moulding pressure, wax- moulding duration, contact pressure) are set by these operating parameters being provided on the rubber mould in the form of defined reliefs which either remain free or can be closed off by a suitable insert. A certain number of such (closed or open) reliefs form a coding field in the form of a binary number, which is sensed by the sensing members of the pressing plate of the wax-moulding plant. As a result, the predetermined operating parameters are taken over by the wax-moulding plant and the corresponding setting and controlling members are actuated. By this automatic setting, once a combination of operating parameters, and thus the wax-moulding result, has been predetermined, it can be reproduced with high accuracy. In addition, more than one person can work on a wax-moulding plant, which increases productivity.

generated by an electromagnetic force generation circuit 
(11) including an electric current inducing component. 
These circuits (10, 11) are connected through and 
regulated by a relay circuit (12). Thus the synthetic 
products of fine structure are obtained.
