The present invention is concerned with the problem of preventing dust-formation on electrode plates of lead. The problem is solved by applying a coating of water-insoluble plastics material on the surface or surfaces of the electrode plate. Examples of suitable materials are polyacrylates, polystyrene, polyvinylacetate and polyvinylchloride. Copolymers may also be used.

A pneumatic yarn splicing device comprises a bracket, a yarn splicing member mounted on the bracket and having a pair of side faces and a yarn splicing hole extending transversely between the side faces, the yarn splicing member including an air ejection nozzle for ejecting a compressed air flow into the yarn splicing hole, and a pair of yarn presser levers pivotably mounted with respect to the br...

There is disclosed a thermosetting phenolic resin composition, suitable for use in injection molding, which resin composition contains a molding grade phenolic resin and an effective amount of a reactive compound (e.g., para-t-butylphenol) that is capable of reducing the viscosity of molding compositions containing said phenolic resin composition to a processable viscosity at a temperature at whic...

A method for repairing perfluorocarbon copolymer cation exchange membranes involves partially solvating a quantity of a perfluorocarbon copolymer having a desired pendant cation-exchange functional group, using a solvating dispersion medium. The composition is applied to areas of the membrane to be repaired and the dispersion medium is then removed.

An easily pumpable, liquid alkali metal, e.g., sodium silicate composition of controlled gelling characteristics contains water, an alkali metal silicate, glyoxal, optionally a Group I-III metal salt, e.g., calcium chloride, and from 0.005 to 0.10 weight/volume percent of sodium bisulfite/sodium metabisulfite, per liter of composition. This composition is easily applied at elevated temperatures, e...

The invention relates to a bed mattress which consists of a fixed or separate uniting member 2, for example a case, a band or a frame, which holds together a system of insert modules 1 in which at least one module unit 6 or 7 is of another type than the other insert module units 8. The uniting member can be formed from foamed plastic or foam rubber in one or more parts with and without a bottom, a...

A load pallet, comprising a deck component and four legs. The aim is to provide a load pallet, attachable with ease to a packing case and which requires little space when stored. Load pallets known in the art are heavily built, difficult to stack and, when stacked, particularly spaceconsuming, and awkward to handle. As taught by the invention, the legs (2) of the load pallet are open in shape and ...

PURPOSE:To constitute a seat position control system as a whole within a single vehicle seat, by arranging an electronic control unit for the vehicle seat in the seat-back thereof so that the electrical wiring between the seat and the vehicle side is reduced. CONSTITUTION:A driver's seat 10 having a seat base 11 and a seat-back 12, is incorporated therein with seat position setting mechanisms such...

A stabilized cream emulsion of tretinoin, capable of being stored without refrigeration for long periods of time without losing therapeutic effectiveness and while maintaining the uniformity and stability of the cream, contains xanthan gum as the stabilizer.

PURPOSE:To reduce the heat from outside and prevent the entering of insects and the like by providing a window screen to be opened and closed independently from a window glass at an opening part. CONSTITUTION:When a fixed hook 12a is pulled upward, a winding roller 12c turns clockwise and a screen net 12b wound up is extended. At this stage, when the fixed hook 12a is hooked at a ditch 11a on a do...

The invention relates to the distribution on a receiving device of fibers carried by a gas current. To improve the distribution, the gas current carrying the fibers is subjected to the action of a gas layer which envelopes the current and of which the direction of flow in a plane tangent to the gas current differs from that of the gas current. The action of the gas layer results in an expansion of...

PURPOSE:To reduce the heating energy of a heating means for sludge in a primary digesting cell, in the system for digesting sewage sludge or the like, by recovering heat by heat exchange between withdrawn sludge and charged sludge. CONSTITUTION:Charged sludge is heat-exchanged with withdrawn sludge by a heat exchanger 13 provided on the way of a pipe line 4 for charged sludge, further heated by a ...

PURPOSE:To reduce the heating energy of a heating means for sludge in a primary digesting cell, in the system for digesting sewage sludge or the like, by recovering heat by heat-exchange between sludge from the primary digesting cell to the second digesting cell and charged sludge. CONSTITUTION:Raw sludge is passed through a pipe line 4 for charged sludge, heated by the second heat exchanger 13, f...
