PURPOSE:To suppress the formation of basic lead carbonate and improve the life of a battery by assembling a green plate without drying it after active material paste is filled in a grid and is aged and naturally drying it in a battery case. CONSTITUTION:When a green plate is naturally dried in a battery case, since it is hardly affected by carbonic acid gas, the carbonization of an active material...

The apparatus comprises around a nozzle supplying the mixture to be treated, a rotating sealed enclosure wherein an annular partition separates two chambers communicating together via a peripheral passage, containing chiefly the separated heavy phase and light phase and provided with thresholds for the draining thereof. According to the invention, the two chambers are equipped with separate centri...

The invention relates to a device for generating images of an object under examination by means of nuclear magnetic spin resonance, with means (4) for positioning and means (1, 6, 7) for applying magnetic fields to the object under examination, for high-frequency excitation of the nuclear magnetic spin resonance and for position-dependent reading of the nuclear magnetic spin resonance of the objec...

An actuating magnet, in particular a direct-current actuating magnet, for a hydraulic valve has a magnet housing (1 to 4, 12), in the accommodation space (16, 17) of which an armature (15) is accommodated so as to be movable in a reciprocating manner. The armature (15) subdivides the liquid-filled accommodation space into two sections. So that a retarding device connected between the actuating mag...

A practice for applying indicia to the surface of a precious stone wherein a source of laser energy is directed at the stone surface and controlled to inscribe the surface with the desired indicia.

A rotary die cutter for die-cutting blanks one after another has a blank feed unit, a pair of cylinders for die-cutting the blanks, and an endless member running synchronized with the cylinders. The blanks are gripped by grippers mounted at equal spacings on the endless member. The cylinders are adapted to allow the grippers to pass between the cylinders while gripping the blanks.

Mixtures which are used for the production of polyurethane foam and which contain amines having primary or secondary aliphatic hydroxyl groups, and also customary quantities of trichlorotrifluoroethane and/or trichlorofluoromethane as a blowing agent, can be stabilized against the premature reaction of the components by adding 0.05 to 5% by weight of 2,4-diphenyl-4-methylpentene in which the ratio...

Means are provided in the beam path of the infrared laser for interrupting the beam and for polarizing and attenuattng the beam. Beam expanding means are provided in the beam paths. Wave front correction means ar...

This binding of the type comprising a first member mounted on the ski and a second member in the sole of the boot comprises a device which automatically closes the cavity (222) of the heel of the sole (202) of the boot (201) and which encloses the locking and unlocking mechanism comprising the plate (205) fastened onto the ski (203) and the articulated fastening lock (216) mounted in the boot (201...

A toe holder for safety ski bindings having a housing, an axle attached to the housing and perpendicular to the top surface of the ski, a sole engaging unit pivotally mounted to the axle and movable between a skiing and a releasing position, and a spring biasing the sole engaging unit towards its skiing position; the axle having a guide groove for urging the sole engaging unit upwards along its pi...

An electronic ski binding including orthogonal, obliquely mounted transducers for detecting oblique components of skiing forces applied to the binding. The binding may include isolation means for structure the transducers from the effects of ski bending. A means of mechanical compensation for the forces applied to the binding by the leaning of a skier may be included. A pivoted linkage between a s...

The invention simplifies a safety ski binding which is arranged at one end of a ski boot and, for its release, can be pivoted under excessive loading in all directions. For this purpose, a vertical pivot pin is provided, on which a pivot piece is mounted so as to be pivotable about the axis of said pivot pin. This pivot piece bears a holding jaw for engagement with the ski boot and a rocker which ...

The vertical pipe (2) of the garden umbrella is connected by means of a central articulation (4) to a cantilevered transverse support arm (3) on which the umbrella canopy (6) is articulated. The central articulation (4), situated outside the covering region (17) of the umbrella canopy (6), has a single screw (7), on the loosening of which the umbrella canopy (6) can be moved in any desired directi...

Thermoplastic synthetic resin foam articles are described which, in accordance with machine production, are elongated principally in the longitudinal direction and have a cross sectional dimension of at least 6.35 mm and a cross sectional area of at least 51.6 cm<2>, where the cells have a mean cell size in the range from 0.1 to 1.2 mm. These cells contain at least one low-permeability halogenated...

An ignition-retarding adjuvant for rigid or unplasticized polyvinyl chloride comprising a compound capable of assisting kinetic control of the evolution of hydrochloric acid and a catalytic composition of salts of at least one transition metal capable of reducing the conversion to benzene and other aromatic compounds inherent in any pyrolytic degradation of polyvinyl chloride.

Method of producing a phenolated resin which can be used to form heat stable (up to 250 DEG ) products. An aromatic hydrocarbon (e.g. toluene) formaldehyde condensation resin is prepared. The low molecular weight contaminants are removed by a distillation process. The residue contains less than 1% low molecular weight material, and is phenolated to give the final resin. The resin may be cured...
