Patent EP-0024748-A2 (EP)
Inventor: VAN DEN BERG JOHANNES VINCENTI
IPC: B06B1/18
Filed: 1980-02-08
Abstract: The main object of this invention is the generation of pressures, forces, flows and motion and several methods are given in principle concerning the application of the hydraulic scheme as well as the constructions which are especially suitable for the generation. 
     Characteristic for these hydraulic schemes are the consistent pressure or volume controlled schemes and the flexible adjustment between the motion of the piston and the motion of the hydraulic flow. With this a universal rotating control valve is important; characteristic of it is the adjustability of the relative opening times in different phases. Further a mass motion reactorwhich transforms kinetic energy into pressure. The applications are mainly related to transport under influence of shock, asymmetric vibrations, dynamic effects by asymmetric vibrations and effects on the frictional resistance by vibrations and savings in and simplification of constructions by replacement of static forces which require a frame through dynamic forces where the reaction is supplied by the inertia of a mass, where this is useful for the speed, and the simplicity is the pneumatic drive combined with the hydraulic drive.

Title: Products containing polymer chains, preparation and use thereof
Inventor: TEYSSIE PHILIPPE
IPC: C08F8/42
Filed: 1982-01-18
Abstract: The invention relates to a process for preparing products containing polymer chains in which a linear prepolymer or polymer contains at least one free acid group at each chain and is reacted with an alkoxide of a metal having a valence of more than 2, such as zirconium, titanium or cerium, possibly in the presence of a non polar solvent, the alkoxide of the metal having a valence of more than 2 being used in such a quantity that the alkoxide functions are in excess with respect to the stoichiometric amount of the acid functions carried by said linear prepolymer or polymer, the reaction mixture being stirred in the presence of humidity until a product is obtained wherein the hydrogen atoms of the free acid end groups of the prepolymer or polymer are substituted by an atom of the metal (M) which is itself linked to another atom of said metal by M-O-M linkages. The invention relates also to the products containing a prepolymer or polymer  alpha , omega -diacid in which the hydrogen atoms of the free acid end groups of the prepolymer or polymer are substituted by an atom of the metal (M) which is itself linked to another atom of said metal by M-O-M linkages, said products being in the form of homogeneous gels in a non polar solvent such as toluene.

IPC: B67C3/24
Filed: 1982-11-25
Abstract: An improved liquid filling valve for filling containers with carbonated liquid such as soft drinks is disclosed which features concentric valves for introduction of the counterpressure gas and product into the container. The container is moved into sealing engagement with the valve which movement is continued to open the valve for admission of counterpressure gas. After counterpressurization is completed the valve for admission of product opens automatically allowing product to fill the container. After filling is completed, motion of the container away from the valve automatically closes it. In the bottle filling embodiment, motion of the bottle away from the valve additionally uncovers a snift port. The counterpressure filling and snifting of containers with carbonated liquids is thus accomplished without use of external valve operating cams or the like.

Abstract: A separator-spacer sheet (28) has a microporous mid-portion surface (30) recessed from non-porous side portions (31). Projections on the mid-portion surfaces (30) maintain a spaced compartmental distance between those surfaces and a sheet electrode (29). The electrode (29) has a flat conductive surface (33). An electrochemical cell system contains both the separator-spacer (28) and electrode (29) in close contact, and electrolyte flows through the compartments between the projections. The system can be one or more stacks of such cells, constituting a battery, electrolyser or fuel cell. A leak- and impact-resistant electrochemical construction comprises an inner compartment for a bromine-rich phase, a second chamber for one electrolyte, a third chamber surrounding the other two for a second electrolyte and an outer casing surrounding all three.

Abstract: The closure has a container orifice (1) with an external thread (2) and a screw-cap (3) with an internal thread (4). The screw-cap has a sealing portion (5) which can be brought into sealing engagement with the container orifice. In order to avoid a sealing on the screw thread and thus the risk of the screw-cap jumping off when it is screwed on, spacer cams (7) are arranged on the thread flanks, which spacer cams hold the thread flanks in a relative position to one another in such a way that a venting channel (11) is produced between the flanks. By this means, the internal pressure in the container is reliably reduced via the thread during screwing-on of the screw-cap as long as said thread is still in firm engagement. <IMAGE>

Abstract: @ A series of first parallel printed contacts extends inward from a beveled first end of a card. Conductors extend over the surface on ends of the contact and are electrically connected together and with large contact terminals at the ends of the parallel series of contacts. 
     A second parallel series of contacts extends inward from the beveled first edge on the second side of the card, and conductors are looped around each other and individually terminate in a triangular array of connectors which extend through the card to make electrical contact with the first conductors on the first surface. Large end contact terminals are provided at ends of the second series of contact. Adhesive-backed covers cover the conductors and connectors and inner portions of the contacts and terminals. 
     The first conductors and second conductors are so arranged that large sections of each conductor in one group of conductors do not overlie conductors on the opposite side of the card. Holes can be punched through the card in selected locations to selectively interrupt conductors on one side of the card without interrupting conductors on the opposite side of the card.

Abstract: A ZIF connector for establishing an electrical connection between the I/O pads (110) of an edge-connected printed circuit board (100) and a set of printed conductors (13) may have one row of or two opposing rows of contacts (50), adjacent or both adjacent and opposite ones of the contacts having different lengths. An upper housing (30) has a plurality of cams (40) mounted thereon, each cam having a different cam surface profile (42). The surface profiles of the cams are staggered into two different lengths corresponding to the lengths of the contacts so that when the cams are actuated by imparting a vertical motion to the upper housing, the contacts will simultaneously engage the 1/0 pads in a staggered fashion. Moreover, the surface profiles of the cams are constructed so that after simultaneous engagement, the contacts perform sequential wipe cycles on the pads. The staggered and sequential wipe cycles promote the stability of the board within the connector without sacrificing electrical integrity.

Abstract: © A resin-impregnated substrate for printed circuits is disclosed, which substrate comprises a fabric woven from warp and fill yarns of glass filaments. The yarns have substantial the same number of filaments therein and are substantially elliptical in cross section when woven. The transverse axis (26, Fig. 4) of the warp yarn (24) cross sections has a length that is at least 75 percent of the length of the transverse axis (27) of the fill yarn (25) cross sections. This ensures a thorough impregnation of the fabric by a resin so that voids (16, Fig. 2) are avoided which, when filled with materials other than resin, such as plating solution, ultimately produce circuit failures.
