Patent EP-0456857-A1 (EP)
Inventor: BRUECKNER ROLAND DIPL-ING
IPC: H04L25/02
Filed: 1990-05-16
Abstract: A digital signal circuit (DS) is formed from a conductor-individual driver circuit (TR, TRN), a gate circuit (G) and a circuit unit (PF), where the circuit unit (PF) is composed of two compensating paths (PF1, PF2). The compensating paths between the conductors (L1, L2) are designed in such a way that an N-channel CMOS switching transistor (SN) and a diode (DN) are disposed in series in a first compensating path (PF1), while a P-channel CMOS switching transistor (SP) and a diode (DP) are disposed in series in a second compensating path (PF2). Due to corresponding operating potential states on the conductors (L1, L2) and the associated control pulse strings for the main drivers (HA1, HA2), one compensating path (PF1, PF2) becomes conductive in each case during the changeover of the complementary conductor potential (VDD, DG) on the conductors (L1, L2) and effects a potential compensation on the conductors. The diodes (DN, DP) connected in each case in series to the switching transistors (SN, SP) in each case prevent a short-circuit between the conductors (L1, L2) connected to different operating potential sources (VDD, DG). <IMAGE>

Abstract: A fuel injection nozzle for internal combustion engines has a valve member slidable in a bore within a nozzle body. A first bore portion (12) in which a first valve member portion is a close sliding fit extends from an end face (8) of the body (1). The first bore portion (12) is connected by an annular recess (13) in the wall of the bore, forming an undercut bore portion, to a second bore portion (15) which surrounds a reduced diameter portion of the valve member, the end of which seats in the closed condition of the nozzle on a valve seat (18) formed in the nozzle body (1). This prevents the access of fuel from the undercut bore portion (13) via the second bore portion (15) to one or more spray holes (20) formed in a tip portion (5) of the nozzle body. A fuel supply passage (24) extends from the end face of the body within the body wall and intersects an eccentric extension (26) extending from the undercut bore portion (12) for the supply of fuel thereto, the intersection including the portion of the eccentric extension closest to the end face (8).

Abstract: The device comprises: main body 1 supporting a pin 2 fitted with a disc 5 having a notch 6. About the pin pivots a non-slip drum 11 rotated by the belt, with the roller 12 forcing it to rub lightly over it. If its speed of rotation is low, the ratchets 7 or 8 fall under the effect of gravity into the notch 6 taking with them the pin 2 which,  as a consequence of the presence of two flats 3, allows the stirrup 14 to drop and, owing to its eccentric point of articulation 27, jams the belt so that it cannot rewind. If the belt is pulled, the stirrup is lifted back, a counterweight restores the pin to its initial position, and the belt can freely rewind. In the event of sudden deceleration, a counterweight frees the belt. <IMAGE>

Title: Rotary dipper stick.
Inventor: WEYER PAUL P
IPC: E02F3/30
Filed: 1990-04-12
Abstract: A vehicle having a fluid-powered rotary dipper stick assembly including a boom attachment head and a bucket attachment head with a body extending therebetween. An axle extends from the boom attachment head into the body and is in sliding engagement with an inward wall of the body to provide lateral support thereto. The axle extends to a midportion of the body. The body is rotatable relative to the axle, and is rigidly connected to the bucket attachment head for rotation together as a unit. A hydraulic motor is operable to produce rotational movement of the body relative to the non-rotating axle. Rotational movement of the body produces rotation of a bucket or other work implement attached thereto about the body longitudinal axis independent of the boom attachment head. The assembly uses a single thrust bearing positioned between the body and the boom attachment head to carry thrust loads in both directions. In one embodiment, fluid passageways in the non-rotating axle and a rotary fluid joint conduct hydraulic fluid between the non-rotating and rotating components.

Abstract: In known filter devices, there is the disadvantage that the pushing-on of a filter bag, its fixture and its release are sometimes very awkward. The new device simplifies these operations and thus the overall handling considerably. This is achieved in that the holder consists of a closed, ovally deformable ring (3), on which the two tensioning segments (5), which are located spaced apart opposite each other, can be moved parallel to one another over the entire length. Due to the possible great reduction in diameter, this design allows a simple pushing-on, e.g. of a paper tea bag, and also its secure fixture and release without problems. <IMAGE>
