Patent EP-0155542-A3 (EP)
IPC: H05K7/10
Filed: 1985-02-23
Abstract: Die Fassung (10), die sich insbesondere für Relais zum 
Schalten von hohen Strömen eignet, weist zum Einstecken in 
eine gedruckte Schaltung aus dem Gehäuse (11) ragende 
Anschlussstifte (19) auf. Alle Anschlusstücke (21), welche der 
Kontaktierung der Kontaktstifte eines Relais oder dergl. 
dienen, sind gleich ausgebildet. Die Anschlussstücke (21), 
welche die z.B. über die Relaiskontakte fliessenden hohen 
Ströme leiten müssen, sind direkt mit den Anschlussklem­
men (29) in Verbindung, so dass diese Ströme nicht über die 
Leiterbahnen der gedruckten Schaltung geführt werden 
müssen. Trotzdem weisen aber auch diese Anschlusstücke 
(21) einen Kontaktstift (19) auf, so dass die Möglichkeit eines 
Anschlusses zu einer Anzeigevorrichtung oder anderen 
Vorrichtungen, z.B. über die Leiterbahnen der gedruckten 
Schaltung, besteht. Die Fassung (10) hat eine längliche Form 
und die Anschlusselemente (33) der Anschlussklemmen (29) 
sind an einer Schmalseite angeordnet, so dass mehrere 
Fassungen (10) auf der gedruckten Schaltung aneinanderge­
reiht werden können.

Abstract: Es wird ein Verfahren zur Herstellung von durchkontak­
tierten elektrischen Leiterplatten beschrieben, bei dem eine 
Platte aus Isolierstoffmaterial mit in rasterartigem Muster 
angeordneten Durchkontaktierungslöchern versehen wird, 
deren Wandungen mit einer Metallschicht überzogen wer­
den und die auf mindestens einer Seite mit einer leitfähigen 
Metallschicht bedeckt wird. Die Metallschicht wird nach 
dem Metallisieren der Löcher bildmässig abgedeckt, und 
die nicht abgedeckten Bereiche der Metallschicht werden 
entweder durch Metallablagerung verstärkt oder durch Ät­
zen entfernt. Zugleich mit der Metallschicht wird ein Teil 
der Löcher in der Weise abgedeckt, dass im fertigen Pro­
dukt nur der gewünschte Anteil aller Löcher als Leitkontakt 
wirksam wird. Das Verfahren erlaubt die Fertigung von vor­
gebohrtem bzw. vorgelochtem und vormetallisiertem Ba­
sismaterial für gedruckte Schaltungen in Grosserie.

Abstract: A split ring clamp having a hard, serrated interior sur­
face is urged against an electrically conductive lead by 
means of a pivoting cam lever. The conductive lead includes

buildup and undesirable resistive heating effects in the 
powering of superconducting electromagnets disposed 
within a cryostat, particularly a cryostat containing liquid 
helium as a cooling fluid.

Patent EP-0174138-A3 (EP)
IPC: B62D5/04
Filed: 1985-08-22
Abstract: An electrical power assisted steering system for a 
vehicle. The system includes a battery (20), having two 
terminals at different voltages and a center tap, and a 
bidirectional electric power assist motor (10) having two 
terminals, one terminal being connected to the centre tap of 
the battery. In an electric vehicle, said battery would be the 
traction battery. A control circuit (28) responds to movement 
of the vehicle's steering wheel (12) to generate a pulse width 
modulated (PWM) signal to drive the motor (10) to assist in 
steering. The pulse widths are directly proportional to the 
driver's rotational displacement of the steering wheel and 
the amount of current flowing through the motor and 
inversely proportional to the speed of the vehicle. The PWM 
signal is applied to a selected one of two driving transistors 
(24,26), the first of which is connected between one of the 
terminals of the battery (20) and the free terminal of the 
motor (10), the other of which is connected between the 
other terminal of the battery (20) and the free terminal of the 
motor (16). Upon receipt of the PWM signal, the selected 
driving transistor (24,26) connects the motor (10) to its 
associated terminal of the battery (20) to cause the motor to 
turn in a desired direction and deliver torque proportional to 
the width of the pulses.  
     Also disclosed are monitoring circuits (74-82) which 
monitor the operation of the control circuit (28) and discon­
nect the motor (10) from the battery (20) when a malfunction 
is detected.
