Patent SE-0601738-L (SE)
Inventor: SALOVAARA KIM
Filed: 2006-08-25
Abstract: An improved device for over-voltage protection is disclosed. A triggerable three electrode GDT (Gas Discharge Tube) is in the device used for discharging voltage. The GDT is connected between an input of the device and ground, and has its trigger electrode connected to a secondary side of a transformer. The transformer is arranged for producing a trigger signal in response to a voltage on the input for triggering said GDT into a conducting state. According to the present invention, a primary side of the transformer is connected to the input via a capacitor and a resistance, wherein a current flowing from the input through said resistance charges said capacitor when the voltage on the input increases. A thyristor is connected to ground, from a point between the resistance and the capacitor. The thyristor is arranged to start conducting when the input voltage reaches a predetermined level, thereby discharging the capacitor through the thyristor to ground and creating a pulse on the primary side of the transformer. This pulse is then transformed into the trigger signal by the transformer.

Abstract: Single crystal silicon structures are bonded to a dielectrically isolated single crystal silicon substrate for high temperature applications where junction isolation is ineffective. One or both single crystal silicon structures are provided with a thin silicon dioxide insulating layer and a thicker deposited boric oxide-silicon dioxide glass bonding layer. Bonding at an elevated temperature under pressure is at a sufficiently low temperature that there is no effect on silica or the previously fabricated components. The process is suitable for other semiconductors and glass compositions.

Abstract: In a sliding caliper disc brake actuator, an actuating shaft 39 is rotatable to rotate a helical cam element 23 that in turn axially displaces a non- rotating cam element 22. The elements 22 and 23 are located in a bore 21 in a caliper leg 16 with an automatic adjusting mechanism 18. A helical return spring 58 acts via a washer 59 to bias the cam elements together and a push rod 53 of mechanism 18 is held against rotation by washer 59. A nut 48 of mechanism 18 is threaded onto the rod 53 and engaged by the cam element 22 to transmit axial force to the push rod 53 and relative extension of the push rod from the elements 22, 23 is accomplished by a one-way spring brake 72 acting on the nut 48 and a disc clutch drive 63 to 69 between the cam element 23 and the nut 48. Lost motion is provided at the clutch drive or the spring brake to prevent rotation of the nut 48 on the rod 53 during normal clearance, and rotation of the nut on the push-rod occurs when excessive clearance occurs. <IMAGE>

Abstract: A massive piston, which might be called a "ram", except that it does not strike anything during operation, reciprocates with bouncing action up and down within a cylinder. An annular pressurized gas storage chamber encircles the piston and travels up and down with it. Pressurized gas is continuously supplied into this movable chamber to be temporarily stored therein. As the piston descends toward the lower end of the cylinder, pressurized gas from this travelling chamber is automatically suddenly allowed to bypass the lower portion of the piston, thereby injecting the pressurized gas into a bounce chamber between the descending piston and a bottom assembly. When this pressurized gas rushes through the bypass, it forces an exhaust valve closed. The bypass includes two vertically spaced sets of gas feed ports communicating into the cylinder, and as the piston continues descending closer to the bottom assembly, the injected pressurized gas is suddenly trapped becoming further compressed as a cushion with great pressure multiplication below the descending piston, thereby producing a powerful driving thrust while bouncing the piston upwardly in a powerful bouncing action. As the piston ascends, additional pressurized gas automatically bypasses from the storage chamber into the cylinder, and its expansion aids in propelling the piston up relatively high. The ascending piston allows gas expansion, until pressure has dropped approximately to atmospheric, thereby allowing the exhaust valve to open. When this valve opens, the piston is near the top of its stroke, and the cycle repeats.

Abstract: A printing mechanism, particularly for a counter device which records distances, is formed with a pair of sets of print wheels with a housing defining a slot through which a voucher may be passed to have imprinted thereon information contained on the print wheels. Platens are arranged to press the voucher against the print wheels and platen carriers which are rotatably mounted have the platens eccentrically mounted thereon. Overcenter springs engage the platen carriers, and after the carriers have been rotated through a predetermined angle, the overcenter springs drive the carriers through a further angle of rotation during which the platens are pressed against the print wheels during the printing process. The angle through which the platen carrier is initially rotated to load the overcenter spring is less than the angle through which the platen carrier is driven by the loaded overcenter spring.
