CONSTITUTION:Bipolar plates 8 united with frames 4 are stacked with separators 9 impregnated with electrolyte interposed respectively, and the frames 4 are melt-bonded at edges 7. End bipolar plates 81, 82 have positive active material 51 and negative active material 61 ...

A method for making an article containing and adhesively bonded joint by first placing the surfaces (30) to be bonded in the path of an intense energy beam (34), such as a laser beam, for a short duration to modify the surfaces (30). Then an adhesive is applied to the modified surfaces (30) and the joint is completed. The inventive method results in stronger and more durable bonds relative to untr...

A negative electrode for lead accumulators has the shape of a rectangular planar grid plate (11) consisting of expanded copper metal which serves as a carrier for the active mass and for the supply and extraction of current. The grid plate (11) consists of two side regions of expanded copper metal (14) and a copper strip (12) which is arranged between them in one piece therewith, and which project...

In a method of manufacturing accumulator plate sets separator sheets (15) consisting of glass fleece are cut to size and are adhesively bonded to form pockets after being folded around a positive grid plate laid thereon. A predetermined compressive stress is maintained in the plate set (18) by bands (21) placed around it, whereupon the plate sets are then inserted into an accumulator housing (20).

A fastening arrangement for connecting a knife to a cutter shaft, having a movable connecting member between the cutter shaft and the knife, it being possible for the cutter to be demounted from the connecting member and mounted on the connecting member without using tools. In order to considerably simplify the known fastening arrangements whilst reducing the components and simultaneously having a...

Two parallel-inserted thread ends are introduced into a thread end preparation device via an air gap located above a preparation tube. The thread ends are cut by shears and thereafter an air flow produced in an air intake tube blows the thread ends into the preparation tube. The prepared thread ends are brought by retracting levers into the vicinity of the splicing chamber. The splicing chamber is...

An installation having at least one beating mill (1) has a separating device (13) which is separate from this beating mill (1) and to which an ejection channel (8) leads which leads tangentially out of the grinding chamber (4). The particles of ground material are therefore thrown into the ejection channel (8) by means of the rotor (3) of the beating mill (1) and thus brought directly into the sep...

The invention relates to a roving-bobbin transport trolley, especially for taking over roving bobbins from the flyer and for transferring these to the ring-spinning machine. This bobbin transport trolley is used in spinning mills. By means of this invention, bobbin transport between the flyer and ring-spinning machine is further simplified. An exact extraction and feed of roving bobbins is guarant...

A process for augmenting production of a specific antibody from a patient including the steps of administering a specific antigen to the patient to cause production of the specific antibody, or choosing a subject containing an antigen, e.g., cancer, or one already immunized or making antibodies to an endogenous or exogenous antigen, performing a thoracic duct fistula on the patient, raising the ce...

A sample yarn-collecting apparatus for preparing a continuous yarn knotted in an end-to-end manner, in which sample yarns having a certain length are collected from a plurality of yarn packages, each of them are connected in succession in an end-to-end manner to obtain one continuous yarn, and the continuous yarn is wound temporarily and thereafter continuously unwound to be fed to testing means w...

An improved method and apparatus for a winder for anchoring an indefinite length of thread supplied from a supply source onto an anchoring disc in said winder. The method comprises the steps of offsetting the thread to a position facing the anchoring disc, spanning the thread vertically, arresting the spanned thread, protruding the thread outwardly from the disc, and displacing the thread slantly ...

PURPOSE:To control an applied voltage to improve the contrast by providing a temperature detecting semiconductor element on an area other than display picture element parts on a substrate in a liquid crystal display device having a semiconductor substrate of thin film transistors (TFT). CONSTITUTION:A gate electrode 11a, an insulating layer 12a, a semiconductor layer 13a, a source electrode 14a, a...

In a safety ski binding, the control surface for the safety release is designed on a front sole projection (50) of the ski boot (30). A spring-loaded locking pin (70d) of the front jaw (70) bears on the control surface (50b) and the bearing surface (50a). In the heel region, the ski boot (30) likewise has a sole projection (40) which engages into a recess (60f) of the heel support (60) and is held...

A pleated media filter element is disclosed which includes pleat spacers which are an integral structural part of the pleated media. The construction of the pleat spacers is accomplished by scoring on the unfolded media a continuous line pattern upon the portion of the media which, when folded, forms a pleat tip of the element. When the scored media is folded into pleats the patterns each define a...
