In the production of veneered profiles, the profiles (2) and the veneers (3) are fed separately to the covering machine, where a heated adhesive (4) is applied to the veneer and the profile and veneer are adhesively bonded together by pressure rollers (1). After adhesive bonding, although the adhesive is cooled off, it is still sufficiently hot for the veneer to detach itself again if stresses hav...

A method is indicated for length measurement on precision winding appliances, which is based on a measurement of the bobbin diameter and on determining the rotational speeds of the bobbin. The variable bobbin width and the variable pitch angle of the thread helix during the winding operation can be taken into account or a correction by the introduction of variously designed correcting cycles can b...

A system for detecting missing or superimposed sheets fed to a sheet processing machine uses a measuring device for generating a signal increasing with the number of superimposed sheets and an evaluating device for emitting an electrical signal when irregularities occur. A pulse transmitter is synchronized to the sheet feed mechanism and operates to emit an initial and final pulse timed to the she...

In a transmission of the type which includes a main transmission mechanism equipped with gear trains of a plurality of transmission stages disposed between an input shaft capable of being connected to a crank shaft of an engine and an output shaft parallel to the input shaft and a sub-transmission mechanism transmitting the driving force from the input shaft to a driven gear of the output shaft vi...

A pneumatic tire whose inner wall is provided beneath the crown with a lining which extends at least from one shoulder to the other of the tread and comprises a layer of a sealing mixture capable of flowing into a puncture hole, the layer being covered radially inward by a vulcanized elastomeric partition, is improved due to the fact that the layer of sealing mixture has a base of at least one ela...

A pneumatic tire having, between two vulcanized elastomeric partitions, a layer of a sealing mixture arranged on the inner wall of the cavity of the tire, at least below the crown and from one shoulder to the other, is improved due to the fact that the layer of sealing mixture has a base of at least one vulcanizable elastomer of low molecular weight, preferably less than 30,000, contains at least ...

PURPOSE:To suppress fluctuation of characteristics by bending a piezo-electric polymer thin film so that polarization axes of both side cross orthogonally and laminating them, and slicing one part of electrode into multiple strips at specified interval and forming its lengthwise direction parallel to the bending line. CONSTITUTION:Common electrode 2 is formed on one surface of a piezo-electric pol...

Calculi, stones, calcified tissue and other material are broken down for removal from within a body using laser pulses that are delivered via an optical fiber and have a wavelength, intensity, energy per pulse and pulse duration selected to break down the object into smaller particles without delivering energy sufficient to cause damage to other tissue.

A pair of transfer drums arranged to move to and away from nip-forming relation with a tire building drum on which a tire is being built operate to save building time. Individual strip appliers place two strip components on each transfer drum while the main carcass ply is being wrapped on the building drum. The strip components are together then transferred rapidly and effectively to the tire. The...

A shoulder wedge device for cross-country skis which, in conjunction with a cross-country safety binding, permits release (13) of the foot in a lateral direction. To this end, a rotatably mounted shoulder wedge (4, 40) is provided in conjunction with a plate (2, 3, 12) which is also rotatably mounted and is fixed on the ski (1) in the longitudinal direction of the latter by means of a locking devi...

The invention relates to a safety ski binding with a sole-holder which is held by a spring in its normal position and releases the ski boot by swinging away in the event of overloading. The sole-holder is made of plastic and has inside it an actuating curve, on which a locking part is supported, via which the power of the spring is transmitted to the sole-holder. To permit the uncompromising selec...

Low density foams are prepared from an admixture which comprises an unsaturated polyester resin, a free radical initiator which initiator is activated at temperatures from about 100 DEG to about 400 DEG F, and a compound selected from a t-alkylhydrazinium salt or a carbonylhydrazine. The low density foams have uniform cell structure without cracks or voids and the process is efficient.

A nylon/ethylene vinyl alcohol copolymer (EVOH) blend suitable for extrusion into strong, tough films possessing good oxygen barrier qualities comprises 90 to 20 weight percent of nylon and 10 to 80 weight percent of EVOH; the nylon is compounded with a plasticizing agent which typically lowers the normal extrusion temperature of the nylon (which is in the region of 266 to 282 DEG C) to a temperat...

A granular or powdery resin which is a condensation product of a phenol and formaldehyde, said granular or powdery resin being characterized by (A) containing spherical primary particles and secondary particles resulting from the agglomeration of the primary particles, each of the particles having a particle diameter of 0.1 to 150 microns, (B) having such a size that at least 50% by weight thereof...

A process for the manufacture of a non-asbestos corrugated sheet comprising forming into corrugated form an aqueous slurry of a mixture comprising, on a dry weight basis, 40-60% cement, 30-40% silica and 5-15% cellulose fibres, compressing said corrugated form so produced in a press to reduce its thickness and increase its density, removing said form from said press and submitting said form to aut...

An improved process for the manufacture of vesiculated beads has been developed which can be used for the production of semi-gloss or satin finished paints. The process involves mixing an oil-phase containing a cross-linkable polyester resin in solution with a monomer co-polymerizable with the resin and an aqueous phase containing an emulsifying agent under conditions such that globules of the oil...
