Batteries based on lead chemistry, e.g., lead-acid batteries, are substantially improved through the use of a particular positive material. This material is formed by the electrochemical conversion of tetrabasic lead sulfate (TTB) where this TTB is synthesized at a pH in the range 9.3 to 12 and under reaction conditions that provide a substantial excess of sulfate to the reactive lead. The resulti...

At least one slot blind (10) at the side of the tube, and an optional slot blind (11) at the side of the detector are provided. The slot blinds (10, 11) are individually adjustable in such way, that one or several detector lines are alternati...

The lifting device has a non-stop loader with a supporting grille (6) composed of parallel rods, and an aid device for the grille. The grille lies on a removable rear lifting carrier (3) of the auxiliary stack (4). The rear lifting carrier is on the remote-from-service side of the press, with one end in the lifting device. The other end of the rear lifting carrier on the service side is free. Whe...

A water soluble polymer binder for binding a fibrous substrate comprises from about 25 weight percent to about 85 weight percent of an unsaturated carboxylic acid/unsaturated carboxylic acid ester terpolymer; from about 5 weight percent to about 35 weight percent of a divalent ion inhibitor; and from about 10 weight percent to about 60 weight percent of a hydrophilic crosslinkable polymer. In a pr...

The device is formed of a metallic container which is capable of containing powders of one or more compounds having the general formula TixZryHgz, but is not hermetically sealed, in order to allow the discharge of mercury vapors generated by the decomposition of such compounds. Some possible device geometries are disclosed, as well as some possible arrangements of the same inside lamps. Finally a ...

A combination (5) ottoman, table or desk and a foldable sleeper bed comprises upper (24) and lower (28) wooden frame sections, the lower frame section (28) being configured as an open top box, atop which the upper frame section is located. The two frame sections are interconnected by a pair of opposed four-bar linkages (26, 26') which permit the upper frame section (24) to be moved between a first...

Processes for conducting equilibrium-limited reactions such as esterification and alcoholysis reactions, use two reaction zones. The first reaction zone operates under reaction conditions that retain at least a portion of the product in a liquid phase, and at least a portion of the liquid from the first reaction zone is introduced into a second reaction zone which operates under conditions such th...

Gegenstand der Erfindung ist ein Verfahren zur Herstellung von weichen bis halbharten Polyurethanformkörpern mit verdichteter Randzone mit gegebener Härte und einem deutlich weicheren Zellkern, sogenannten Integralschaumstoffen, bei denen physikalische Treibmittel aus der Reihe der C6-Kohlenwasserstoffe verwendet werden.; The invention relates to a method for producing soft to medium-hard polyuret...

A method and a device for access control, whereby a control unit (13) is operatively connected with a memory (14) for storage of authorized identification numbers for current service or access in a register. The control unit (13) is operatively connected with a telephone unit (12) for reception of an identification number of a calling party by means of a telephone connection made by wireless telep...

The boot fixing (1) has a body (2) which is connected through a mounting base (3) onto an alpine ski. The body has a boot-retaining jaw which is movable in a lateral direction in response to the boot against a return spring (15) housed in the body. A compensator (30) lowers the return force exerted by the spring on the jaw in response to a force exerted on a lever pivoted on the base. A support pl...

The fastening consists of a body (16) carried by a base (17) with a thrust plate extension (30) to support one end of the boot sole. The base is mounted movably on a plate (18) fixed to the ski by means of a horizontal transverse hinge, while a lock (46) holds it in place. A stop (28) which is fixed solidly to the ski limits the upward movement of the base (17), and the lock fixes the base in rela...

By the use of a binder comprising: a) 40 to 70 wt.% of a water-soluble amide material and/or water-soluble amine material and b) 25 to 60 wt.% of a polyamide resin component substantially composed of a polyamide resin material having 10 carbon atoms or more on average between amido groups, a molded article is produced by metal powder injection molding. From such a molded article, the water-soluble...

A method for determining the presence of an analyte in a fluid is described along with an apparatus specifically designed to carry out the method. The method involves taking a reflectance reading from one surface (15) of an inert porous matrix (11) impregnated with a reagent that will interact with the analyte to produce a light-absorbing reaction product when the fluid being analysed is applied t...
