Patent EP-0436047-A1 (EP)
Inventor: RUNGE WOLFRAM
IPC: B41J2/055
Filed: 1990-01-02
Abstract: To increase the degree of efficiency and the working speed of liquid jet printing devices, it is proposed to arrange in each ink duct (12) at least one automatically acting mechanical valve (13,130,14,140) which prevents expansion of the vapour bubble (11) towards the reservoir (16). In this case, the valves are arranged in the form of closure bodies such that they only allow a flow of liquid towards the jet. The actuation of the valves (13,130,14,140), i.e. the movement of the closure bodies, is brought about by the onset of the flow operation and thus requires no external influence. <IMAGE>

Abstract: A circuit breaker comprises a compensator bimetal (2) and a main bimetal (3) which deflect in the same direction when heated. Each bimetal carries an electrical contact (4, 6), which are normally in contact with each other. Upon overload, the contacts open. However, opening of the contacts causes electric current to flow through a heater wire (8) wrapped around the armature bimetal, thereby keeping the main bimetal deflected and keeping the contacts apart.

Abstract: An implant assembly and method is provided, as well as a system and method for exposing an embedded implant after osseointegration has taken place. The implant assembly comprises an implant member for embedding in the jaw and a rest factor member for securing to the implant member, the rest factor member having an upper rest surface just above the tissue level for opposing an overlying portion of a prosthesis anchored elsewhere in the jaw to form a non-­retentive rest or support for accepting down pressure from the prosthesis. The implant member is relatively short and can be installed in distal jaw regions without interference with the mandibular nerve, and has an undersurface having a shape designed for stable integration with the bone while resisting sidesway. The method includes cutting out a bore in the jaw for receiving the implant, inserting the implant and an attached healing screw in the implant, closing the implant site and allowing osseointegration to take place over an extended period, and subsequently uncovering the implant site, removing the healing screw, and securing the rest factor member in the implant.

Title: Multi-layer circuit board that suppresses radio frequency interference from high frequency signals.
Inventor: BARAN JOZEF B
IPC: H05K1/14
Filed: 1990-08-22
Abstract: A multi-layer printed circuit board is constructed to suppress radio frequency interference (RFI) generated by high frequency clock and data signals therein. Suppression is achieved by positioning clock lines carrying the clock signal on a first voltage reference layer proximate to a second voltage reference layer. The two layers shield the clock signal from the signal lines on other layers. Noise may be further reduced by forming bridges in the second voltage reference layer proximate to the clock lines so that the bridges span the width of the clock line. Capacitors are also preferably utilized to further suppress radiated noise. The capacitors provide AC coupling between the first and second voltage reference layers so that a low impedance path is provided for high frequency noise generated by the clock signal. The second voltage reference layer thus operates as an effectively continuous shield between the bridges.
