A process of laminating gold foil includes the steps of pressing a gold piece to form an elongated thin gold foil having an even thickness from 0.3 mm to 1 mm; cutting the gold foil to a plurality of gold foil pieces with predetermined size; placing each of the gold foil pieces between two plastic sanding mold sheets having a size larger than the gold foil piece, in which each of the two plastic sanding mold sheets has an interior sanded surface; pressing the two plastic sanding mold sheets onto...

A sealed-in foil lamp comprising a metal base member of molybdenum and a coating applied on at least a portion thereof, the coating containing ruthenium alone or a ruthenium alloy.

Proposed are stamping foils and processes for the production thereof, which make it possible to form on a carrier film patches which are completely separate from each other and which can be transferred on to a substrate using the procedure which is usual when dealing with stamping foils, wherein the transfer operation can be effected in such a way that no flakes which interfere with subsequent overprinting are formed.

A multi-layer packaging foil having a hologram membrane therein, includes a bottom structure made of plastic material and a top structure made of aluminum foil with a hologram membrane sandwiched therebetween. The hologram membrane is composed of a layer of resin and a thin layer of aluminum with a serration defining a hologram formed thereon so that when the packaging foil is viewed from the bottom structure side, a 3-D image is generated by the serration. Also provided herein is a method for m...

The method for joining a metal foil with a synthetic material foil comprises unwinding both materials from a supply roll each, and subjecting the synthetics foil, prior to the application of an adhesive, to a corona discharge on a narrow border region. The metal foil and the synthetic material foil are then pressed together and irradiated by ultraviolet radiation causing polymerization of the adhesive. The composite foil material thus obtained is transferred to a further processing station. Ther...

A foil-type switching element comprises a first carrier foil having a first electrode arrangement applied thereon and a second carrier foil having a second electrode arrangement applied thereon, said first and second carrier foils being arranged at a certain distance by means of a spacer in such a way that said first and second electrodes face each other in an active area of said switching element. At least said second electrode arrangement comprises a resistive layer which faces said first elec...

In order to be able to realize complicated jaw movements in a device for welding of a foil tube, comprising two welding jaws, which can be moved opposingly and clamp the foil tube between one another, whereby a linear motor is provided as the jaw drive, it is suggested that the gearing houses a cam plate connected to a movable part of the linear drive, that the cam plate has two separate curves, and that each one cam connected to a jaw carrier is guided along a curve.

In order to achieve, in a device for welding of a foil tube comprising two welding jaws, which can be moved against one another and clamp the foil tube between one another, a relatively low building height of the device and a high welding force, it is suggested that a gearing has four rods, of which two inner rods are pivotally fastened through a stationary joint, and two outer rods are each connected through one joint to an inner rod and a further joint to a jaw carrier, and that a movable part...

A foil for the headsail of a sailboat for use with a headstay has an aerodynamic shape. It includes a headstay channel for containing the headstay, which may be snapped into place in the channel. The foil has a first and second sidewall, a forward wall, and two or more tabs on the back of the forward wall, which engage the headstay. A forward luff channel is bounded one side by the first side wall and on an other side by a forward channel inner wall. An aft luff channel isbounded on one side by ...

An apparatus for electron multiplication by transmission that is designed with at least one foil having a front side for receiving incident particles and a back side for transmitting secondary electrons that are produced from the incident particles transiting through the foil. The foil thickness enables the incident particles to travel through the foil and continue on to an anode or to a next foil in series with the first foil. The foil, or foils, and anode are contained within a supporting stru...
