Abstract: An implant for an intervertebral space with a shaped body. The implant has a top contact surface to be placed on a base plate of a body of the vertebra adjoining the implant from above, a bottom contact surface to be placed on a cover plate of a body of the vertebra adjoining the implant from below, two lateral surfaces, a front lateral and a rear lateral surface as well as a central axis that intersects the two contact surfaces, a longitudinal axis that intersects the front and rear lateral surfaces and a transverse axis that intersects the lateral surfaces. The implant also has a central plane situated between the contact surfaces and at right angles to the central axis of the body. The contact surfaces have a plurality of macroscopic teeth with central axes, where the central axes of the plurality of teeth are inclined relative to the central plane in such a manner, that a rotation of the body of 90° about the longitudinal axis is facilitated in one direction and impeded in the other direction.

Abstract: Novel aqueous coating compositions are formed from acidic resins and a metal-polyamine complexer, optionally with organic acids and cometals. The acidic resin is combined with the complexer in the presence of ammonia to form the coating composition, a coordinate which, upon drying, provides films which are water-resistant and have excellent wet/dry rub resistance. The coating compositions are particularly useful for inks, including gravure and flexographic inks.

Abstract: A flexible printed circuit, located within a digital watch, which provides the interconnection circuitry between the digital watch's electro-optical displays and the electronic components and the batteries and the watch push buttons. The flexible printed circuit consists of a pliable plastic material to which battery contacts, push button contacts, interconnection circuitry (between the batteries, watch push buttons, electronic component, and electro-optical displays), and contacts for the electronic components and displays are affixed.

Abstract: Digital display is retained in upper spacer of watch module by means of screws and a spring having resiliently deflected fingers engaging the upper spacer. Resilient deflection at both the screw attached end and the spring finger end resiliently restrains the display and ensures contact of the display with an elastomeric type connector.

Abstract: Electronic substrate of the electronic watch is the principal carrier of the electronics and electrical interconnections. It carries two alignment notches with top and bottom spacers embracing the substrate and engaging the alignment notches. The visual horological display is located in the top spacer and the batteries are located in the bottom spacer. Springs press onto the substrate and are contactable for input to the watch electronics. All important parts are keyed together for ease of assembly and accuracy of alignment.

Abstract: Electronic substrate of the electronic watch is the principal carrier of the electronics and electrical interconnections. Top and bottom spacers embrace the substrate. Contact springs press onto and clamp on the substrate and contact the circuitry on the substrate. The springs are contactable for input to the watch electronics.

Abstract: A digital watch having an elastomer spacer block which houses the watch batteries, the oscillator crystal, and the substrate with its electronics and optical display elements mounted thereon; all in the same cavity. Said digital watch also has a flexible printed circuit which contacts the batteries and electrically connects them to the watch electronics. The flexible printed circuit is also used to turn on and to set the time by grounding the contact on the printed circuit to the case.
