PURPOSE:To uniformalize the thickness of a thin lead sulfate film by allowing an electrode plate filled with paste to vertically pass through between a pair of rollers facing horizontally to each other and having sponge treated to contain diluted sulfuric acid therein by dropping the diluted sulfuric acid onto roller surfaces covered with the acid resistant sponge of a specific thickness. CONSTITU...

PURPOSE:To enable a small-type sealed lead storage battery to be smaller and has a button-like shape by installing pellet-like positive and negative plates composed of a coarsely porous body in a positive and a negative case made of a conductive material respectively, placing the plates facing each other with a separator interposed and joining the cases together with an insulator layer interposed....

PURPOSE:To enable the cost of a small-type sealed lead storage battery to be reduced by bringing a positive and a negative active material into contact with the larger surface and the smaller surface of a deformed lead member having projections which fill the perforations of a plastic plate and is fixed to the peripheries of the perforations. CONSTITUTION:After the projections 4 of a structure 3 m...

A rotor for beater mills equipped with rows of hammers (10) with parallel axes, a plurality of hammers swing-mounted on sleeves (9), the latter being retained in position between rotor disks (2) by means of bolts (8) passing through the sleeves (9) in an axial direction and secured in the outer rotor disks, thus characterized in that the sleeves (9) are mounted in bearing seats (4, 5) provided ...

A front jaw for a safety ski binding includes a support member mounted on a ski having a hold-down cooperable with a ski shoe sole supported for vertical movement, a pair of centering levers cooperable with the sides of the ski shoe sole supported for pivotal movement about vertical axes, and a compensating lever supported for pivotal movement about a substantially horizontal axis. One end of the ...

PURPOSE:To narrow the spaces of each reactor by making the winding direction of the reactor arranged at the center to be the direction reverse to other two in the three-phase air-core reactor disposed onto the same axis through insulating spacers. CONSTITUTION:Each phase reactor winding IU-IW of the three-phase air-core reactor are arranged onto the same axis through the insulating spacers among e...

PURPOSE:To improve insulating performance, and to ameliorate inductance characteristics and loss characteristics by using winding in which the distribution of ampere-turns is formed uniformly and making the thickness of laminating of the magnetic material of a magnetic core the mean diameter or more of the winding. CONSTITUTION:The inside of a reactor with the winding 1, which is formed by winding...

A caliper logging sonde is equipped with a plurality of fingers (54) mounted swivelably with respect to its body member (51). The movement of each finger (54) is transmitted to a respective bar (176) in magnetic material. This bar moves within a longitudinal tube (136) which is mounted in a sealed manner with respect to the sonde body member so that its interior is subjected to the pressure outsid...

1. A sheet of transparent plastics material of high optical quality comprising a layer based on polyurethane having energy-absorbing properties, characterised in that the layer having energy-absorbing properties is formed essentially of a polyurethane obtained by reactive casting on a flat horizontal support of a reaction mixture of an isocyanate component of viscosity less than 5 Pas at 40 degree...

The present invention relates to polystyrylpyridine-type resins having increased toughness, and composite materials containing these resins. The resin of the invention contains a polycondensation product of at least two reactive methylated substituents, the said resin having the following general formula (I): Ux Vy Wz in which: U denotes the grouping V denotes the grouping

Powdered polysaccharide may be made by spray drying an emulsion in a non-aqueous liquid of an aqueous solution of the polysaccharide. Spray dried polysaccharides are novel materials. At least 90% by weight of the particles may be within a size range of not more than 100 microns. The particles may have an average size between 50 and 250 microns or between 10 and 50 microns, and the finer particles ...

The invention relates to furnishing accessories of the lamp type with a wooden structure. It comprises a normal illumination, a secondary illumination - low-voltage halogen type, emitting no significant heat - included in the body of a lamp, which, by diffusing a white or coloured glow through the walls of the uprights through holes, grooves, patterns or combination thereof, brings out the apparat...

A surveillance marker has a semiconductor connected between arms of a dipole antenna, one arm being of non-ferrous conductive material and the other of high permeability low coercivity material such as permalloy. Higher coercivity magnetizable pieces are disposed adjacent the low coercivity arm, and all is sandwiched between paper or other insulating layers. The marker is detected by a combination...
