A machine for applying a configuration of reinforcement/stiffening or decorative material in powder form to a receiving surface (20), for subsequent fusing, cooling and pressing to a substrate such as shoe upper. The machine comprises a deposition station (12), a heating station (14) and a press station (16). A tensioned receiving belt (20) receives the configuration of powder through a cut-out (4...

Method of and apparatus for splicing fibrous formations, particularly yarns. Mutually closely arranged parallel and overlapping ends of the fibrous formations to be spliced are disposed inside the pressure channel of a splicing chamber. The thus disposed fibrous formations are subjected to the whirling action of pressure air and at least at one of the mouth of said pressure channel they are subjec...

Method of and apparatus for preparing and splicing the ends of fibrous formations, particularly in the pressure channel of a pneumatic splicing chamber provided with a displaceable lid. Excess lengths of ends of fibrous formations to be spliced are placed within the pressure channel in overlapping substantially parallel relationship and are then cut to a desired length by cutting means such as sci...

A ski binding having a portion which holds the ski boot and moves relative to a ski over a predetermined distance and in predetermined directions, which may be perpendicular to each other, relative to the ski. The binding employs a mechanical or electromechanical transducer for sensing the skier's movement which triggers a relative movement of the binding. Guides are provided to direct and limit t...

A gas cleaning installation, such as might be used to filter particulate material from exhaust gases of a power generating boiler or the like, which comprises a pair of gas cleaning chambers each containing filtration means for a gas stream passing through the installation. The chambers are spaced apart to define between them a gas inlet passage or passages into the underside of each chamber and, ...

Selectively light transmitting or electrically conductive film having a heat shrinking property and preformed self-supporting flexible laminar structure including said film, which are suitable for a safety glass-type construction use with a good appearance.

A method of grinding metallic ingots into small chips or powder, which comprises the steps of providing a cut ting element including a plurality of teeth, providing a plurality of ingots, each comprising a main body having a lower surface, a front end and a rear end, the rear end having an outwardly extending projection and the front end having a corresponding recess at least partially defined by ...

LAWN UMBRELLA A lawn umbrella having a shade of a rectangular configuration supported by four ribs, the free end of each rib being received in a pouch at a respective corner of the shade. The other ends or two of the ribs are pivotably connected to a collar slidable on the mast, the collar being lockable in operative position by a thumb screw. The other ends of the other ribs are pivotably connect...

An automatic transmission for a city bus and other highway vehicles comprises an engine-mounted gearbox with a laterally offset drive output to the rear wheels through a propeller shaft and differential drive unit. The gear box has four layshafts grouped round the drive input shaft. Multiplate pneumatic clutches, one on each layshaft, select transmission ratios under the control of a driver's sele...

Inspection of micromask patterns occurs by both moving an inspecting laser beam relative to a micromask and varying the intensity of said beam in the same manner that occurs during pattern generation. The pattern modulates the inspecting laser beam by one of reflecting or transmitting a modulated laser beam therefrom. The modulated beam then is sensed and used to produce a modulation signal. The m...

A high water content soft soil, for example from the sea or river bed, may be improved in strength by incorporating thereinto a finely divided, quenched iron blast furnace slag treated with sulfuric acid, and a Portland cement. The sulfuric acid-treated slag is a product obtained by reacting a finely divided, quenched iron blast furnace slag, such as a water-granulated iron blast furnace slag, wit...

In repairing articles of natural rubber or elastomer predominantly of natural rubber with cured polymer or prepolymer (polyurethane/polyurea), adhering advantages are obtained especially at elevated temperatures when the damaged area is treated with halogen-containing oxidant dissolved in 1,2-dichloroethane instead of other solvents.

The invention deals with a method of bonding a poly(vinylidene fluoride) solid to a variety of solid substrates, in an application typically using the piezoelectric properties of the material. The bonding method entails surface preparation of the poly(vinylidene fluoride) by a variety of steps including activation of the surface by plasma etching to cause the surface to wet the adhesive used in th...

Thermally coalescible acrylic resin plastisol or organosol dispersions of reduced viscosity and thixotropy result when 0.2 to 40% by volume of the total volume of the dispersion of a volatile solvent is incorporated in compositions comprising particles of single-phase, random acrylic polymers or copolymers dispersed in nonvolatile plasticizers. Incorporation of a nonvolatile photopolymerizable com...

A PROCESS FOR THE TREATMENT OF FIBRE MATERIALS Articles having improved resistance to water can be obtained from fibre materials by using carboxylated rubber latices having particle diameters of less than 200 nm which have been produced by one-step polymerization at pH-values below 7 in the presence of mono-nuclear-alkylaryl sulfonates and oilsoluble initiators.
