Patent EP-0011413-A1 (EP)
Inventor: AYRES FREDERICK CHARLES
IPC: H01H13/20
Filed: 1979-10-31
Abstract: A push button switch comprises a pair of fixed contact members (2,3; 21,22) which are bridged in the closed condition of the switch by a movable contact member (4; 23) that is biased towards engagement with the fixed contact members (2,3; 21,22) by means of a spring or the like (5; 24). Breaking of the electrical pathway through the switch is achieved by actuation of a plunger (9; 26) which is arranged to bear on the movable contact members (4; 23) so as to pivot it relative to a predetermined one (3; 21) of the fixed contact members at least during the initial travel of the plunger during actuation thereof and so that making and breaking of the electrical pathway through the switch occurs between the other fixed contact member (2; 22) and the movable contact member (4; 23). Only one pair of contacts (6, 8; 29, 30) need be made from fine silver. Forms of switch are illustrated with an essentially planar movable contact member (4) and an asymmetric plunger (9) formed with a nib (13), as well as forms of switch with an L- or 7-shaped movable contact member (23). One of the fixed contact members (21) can have a lip (35).

Abstract: A vehicular air disc brake of the wedge actuator type in which the wedge actuator is secured to the air motor by an annular fastener (42) which is snap locked in place in a blind bore (52) in the free end of the wedge actuator (28b) and which acts to secure the free end of the piston rod (40) of the air motor to the wedge actuator in response to generally linear movement of the piston rod into the fastener. The fastener (42) is split (at 50) to allow insertion into the blind bore (52) in the free end of the wedge actuator, and includes a plurality of finger portions (48) which together define a single helical thread disposed within the blind bore; this single thread allows the threads on the air motor piston rod (40) to ratchet therepast upon insertion of the piston rod. allows the piston rod (40) to be threaded out of the fastener (42) for disassembly purposes. and. in the event of inadvertent backing out rotation of the piston rod. allows the piston rod (40) to reseat in the blind bottom (52f) of the wedge actuator brake in response to the next actuation of the air motor.

Abstract: A multiplex information handling system for a vehicle has number of transmitters (T1, T2) and a number of receivers all interconnected by a common power bus and signal bus (5). Each transmitter is coded and transmits datum bits in a specific serial order. Each receiver contains a R.O.M. to instruct it to respond to a datum bit in a certain position from a certain transmitter. Each transmitter may be provided with means (G1, G3, G2, G4) to abort its own transmission should the waveform transmitted not correspond with the intended waveform and each transmitter and receiver can be connected to the signal bus via fuses such that a faulty transmitter or receiver can be blown off the bus. Means may be provided for detecting and preventing the exclusive occupation of the signal bus by one transmitter. Signal priority establishing means can be provided to control the transmission of signals along the bus representative of the state of control equipment controlled by the system and delay means can delay the implementation of a control signal until a priority remedial signal is received.

Abstract: A logic circuit used, for example, in an electronic computer, comprising an output inverter transistor (Q3) and a switching transistor (Q6) which discharges the base charge stored in the storage capacitance in the base-emitter junction of the output inverter transistor (Q3) when the output inverter transistor (Q3) changes from the turned-on condition to the turned-off condition. A second switching transistor (Q7) is connected between the base electrode of the first switching transistor (Q6) and a node of the logic circuit whose potential rises when the output inverter transistor (Q3) is turned off. 
<??>The second switching transistor (Q7) is turned on temporarily when the output inverter transistor (Q3) is turned off, thereby turning on the first switching transistor (Q6) temporarily. By quickly discharging the base charge, the turn-off-time is minimised, and the transfer characteristic improved. Circuits embodying the invention, such as inverters and NAND gates, use little power, are compact, and may have high input noise thresholds.

Abstract: Es wird eine Eingangsschaltung für einen Feldeffekttransistor (FET)-Speicher beschrieben, die aus einem Bootstrap-Inverter (1 bis 8) besteht, der durch eine dynamisch arbeitende Vorladeschaltung (10 bis 12) zum Vorladen des Bootstrap-Knotens (23) auf die volle Betriebsspannung ergänzt ist und die ohne Zwischenschalten eines aus bipolaren Transistoren aufgebauten Pegelumsetzers direkt mit TTL-Pegeln angesteuert werden kann. Dazu ist die Eingangselektrode des Kondensators (12) der dynamisch arbeitenden Vorladeschaltung an den Ausgang (17) eines auf die Eingangsschaltung folgenden Inverters (16) angeschlossen. Ferner ist ein Entladezweig (13, 14, 15) vorgesehen für den Knoten (20) der dynamisch arbeitenden Vorladeschaltung. Der Entladezweig ist mit seinem anderen Ende zusammen mit dem Gate des Vorlade-Feldeffekttransistors (11) der dynamischen Vorladeschaltung an den Ausgang (19) eines weiteren, auf den ersten folgenden Inverters (18) angeschlossen. Dadurch wird gewährleistet, daß bei dem durch den Bootstrap-Effekt bewirkten Anstieg des Potentials des Bootstrap-Knotens (23) über den Wert VH der Betriebsspannung sich dieser Knoten nicht über den FET 10 zum positiven Pol der Betriebsspannungsquelle entladen kann. Diese würde nämlich dem Potentialanstieg des Bootstrap-Knotens (23) entegegenwirken, so daß das Potential des Ausgangs (8) der Eingangsschaltung nur langsam ansteigen und nicht den vollen Wert VH der Betriebsspannung erreichen würde.
