The invention concerns a method and a device for threading the end of a web (P) from a jumbo roll (30) or equivalent through the winder along a path determined by the members guiding the web (P). In the method the end of the web (P) is passed from the jumbo roll (30) through the winder as of full width by grasping the end of the web (P) placed on the jumbo roll by means of a fetching and grasping ...

The invention relates to a regulating arrangement in particular on packing machines for the feed of weblike packing material in register with decorations or folding indications, so-called crease lines, present on the web. In accordance with the invention the desired control is obtained by regulating the tension of the web with the help of a guide roller over which the web is passed. The speed of t...

This invention relates to a solenoid device for a flow rate control valve and a displacement sensor. In a conventional solenoid device, it is not possible to obtain the characteristics permitting ease-of-control of the voltage applied to an electromagnetic coil and the stroke of a plunger, or the stroke of the plunger and the oscillation frequency of the coil. Thus, it is difficult to carry out a ...

Blood bag having affixed thereto a label, portions of which are adapted to permit enhanced gas transmissibility between the interior and exterior of the bag. In preferred embodiments the affixed label has an outwardly facing surface adapted to provide useful information about the bag or bag contents and an inwardly facing surface having raised portions and depressed portions with the label general...

The invention relates to a safety ski binding, in particular a heel-holder, with a sole-holder 4 which is pivotable about a transverse spindle 3 on a bearing block 2 and is held in travelling position by a catch rocker 7 which is under the influence of a release spring 10. In this connection, the sole-holder 4 is acted on by an opening spring which tends to pivot it into open position. The catch r...

A tooth belt drive has tooth pulleys (5) with evenly distributed interruptions (22) in its teeth to temporarily interrupt the force excitation from the pulleys and to reduce the oscillation amplitude of the free parts of the belt between the pulleys.

A telemetry sub 1 for a drill string 2, 3 comprises upper and lower portions 6 and 7 electrically insulated from one another by an insulator 8. The sub 1 incorporates a transformer 12 having its secondary connected between the upper portion 6 and the lower portion 7. In operation a measurement data signal in the form of pulses is supplied to the primary of the transformer 12 by suitable electronic...

A method of producing polyamide foils by extrusion wherein a dispersion of a solid inorganic nucleating agent is added to the polyamide.

An improved process for the production of cross-linked polyolefin foams by mixing polyolefins with conventional foaming agents and cross-linking agents known for polyolefin foam production, shaping the mixture into a plate or into a continuous sheet, substantially without cross-linking and foaming, the improvement comprises mixing said mixture with up to 50% by weight of an alpha , beta -unsatura...

Polyester resin is expanded and cured using mono-substituted sulfonyl hydrozide blowing agent, organic peroxide curative and certain metal promoters.

In a dry shaver 1 intended for connecting to an a.c. power supply and having at least one cutting blade 13 which can be driven in a reciprocating manner and a self-starting single- phase synchronous motor 19 provided for driving the cutting blade 13, a mechanism 59 coupling the rotor 24 of the motor to the cutting blade is designed as a double cam mechanism which both converts the rotating movemen...

A method for forming a vehicle window assembly includes applying a band of an opaque ceramic enamel material to a predetermined peripheral portion of a sheet of relatively flat glass, and heating the glass to a prefire temperature to fuse the opaque material to the glass. An electrically conductive material is applied to the band in a predetermined pattern to form a pair of bus bars typically alon...

An electrode assembly for polarographic assay of glucose in solution having a laminated membrane, the outer membrane being from l to 20 m thick and having a pore size of 10 to 125 A, the inner membrane having a thickness of 2 to 4 m, and bonded to the outer membrane with immobilized glucose oxidase. Rapid assays are carried out by measuring the current difference before equilibrium is attained and...

An improved bone cement is comprised of a particulate biocompatible calcium phosphate ceramic and particulate resorbable calcium salt dispersed in a cross-linked biodegradable polyester matrix. The polymer/salt-particle composite exhibits good biomechanical strength/modulus characteristics with surgically acceptable cure times. When used for sustained release of biologically active agents in a phy...

In a dry shaver with at least one roll-type cover (4), slidable on the apparatus housing (3) and serving to cover or free a screen shaving foil as desired, the wall face (14) of the roll-type cover facing the apparatus housing extends at a distance from the apparatus housing, at least one slideway (15; 16) being active between the roll- type cover and the apparatus housing, producing a contact pat...

A water purifying method, particularly a sewage purification method, for eliminating nitrogen therefrom, in which (a) the water is subjected to a preprecipitation process with the aid of trivalent and/or multivalent metal salts for prereduction of incoming contaminants; (b) the NO3 present is reduced to nitrogen gas by anaerobic fermentation, in which readily decomposed organic material serves as ...
