Title: Marking film and method of marking a vulcanisable article
Inventor: GAERTNER HELMUT
IPC: G09F3/00
Filed: 1988-06-13
Abstract: The invention relates to a method of marking a vulcanisable article, and to a marking film. The articles to be marked are, for example, rubber hoses. To permit marking which is durable and adequately resistant mechanically, it is provided according to the invention that a coloured, vulcanisable layer 1 is applied to a backing film 2 and that subsequently the backing film 2 is bonded with an impressible film 3. The marking film thus produced is provided with impressions 5. During the vulcanising operation, the coloured layer 1 bonds with the article to be marked, the impressions 5 being filled by the material of the article. According to the invention, the backing film and the impressible film are subsequently removed from the article. The invention can be used for marking any vulcanisable articles, in particular for marking rubber hoses (Figure 2). <IMAGE>

Title: All-wheel steering system for motor vehicles
Inventor: BUFLER ERNST
IPC: B62D7/15
Filed: 1988-06-22
Abstract: In known all-wheel steering systems, in which the transmission ratio between the rear-wheel deflection and the front-wheel deflection can be continuously varied with the aid of mechanical actuating means, in particular as a function of the vehicle speed, troublesome toe-in changes at the rear axle are associated with the control of the transmission ratio. The new all-wheel steering system is intended to permit continuously variable control of the transmission ratio, likewise by mechanical means, but without affecting the toe-in at the rear axle. For this purpose, the translational or rotary motion of a transmission member leading to the rear axle is transmitted via an intermediate member pivotable about a hinge axis as a function, for example, of the vehicle speed to a steering rod articulated on parts of the rear-axle steering linkage. The point of application of force of the steering rod on the axle with the steering wheel in the straight-ahead position lies precisely on the imaginary extension of the hinge axis of the intermediate member, such that, as the intermediate member is pivoted, the steering rod describes the lateral surface of a cone with the point of application of force on the axle as the tip of the cone. <IMAGE>

Title: Apparatus for the mechanical stimulation of a flowable material in a container by means of ultrasound, with monitoring of the filling level of the material in the container
Inventor: SCHWANK HORST
IPC: B08B3/12
Filed: 1988-08-01
Abstract: Monitoring the filling level of the material in the container which is to be mechanically stimulated by means of ultrasound is to be carried out in such a way that, in the event of undershooting a predetermined filling level in the container, a signal is output which is as far as possible independent of possible disturbing influences and can be reliably defined and, if necessary, the energy supply to the ultrasonic vibrator is interrupted, so that destruction of the ultrasonic vibrator, its becoming unusable or only a reduction of the efficiency because of partial overheating of the ultrasonic vibrator is reliably avoided. In order to carry out the monitoring of the filling level with a low expenditure and as far as possible independently of disturbing influences in such a way that even a small impairment of the functioning of the ultrasonic vibrator used to stimulate the material in the container is reliably avoided, a transmitter-receiver arrangement using ultrasound as the signal carrier is used for the monitoring of the filling level, in which the receiver for ultrasonic signals is positioned at a predetermined height above the floor of the container on the container wall and is connected via an electrical evaluation circuit to means for interrupting the supply of energy to the ultrasonic vibrator and/or to indicating means for the filling level of the material in the container. The apparatus is suitable for the atomisation of a pulverulent or liquid material, for example for the generation of therapeutic ... Original abstract incomplete.

Patent DE-3928569-A1 (DE)
Inventor: KOSKENMAKI DAVID C
IPC: C23C14/14
Filed: 1989-08-29
Abstract: An array of densely packed discrete metal microspheres which may be deformable and electrically conductive are formed on a substrate by a method including the steps of providing a substrate having a depositing surface in the chamber forming a metal vapor in the chamber and depositing the metal vapor on the depositing surface, the depositing surface having a temperature at or above the melting point of the metal. The metal may be Pb, Sn, In, Bi, Zn, Cd, Tl, alloys thereof and mixtures thereof. The microspheres may have an average diameter of 0.1-5 micrometers. For the metal to form microspheres it should be able to condense in the form of discrete liquid droplets and this is achieved by the metal having a vapour pressure at its melting temperature, or throughout its range of melting temperatures, which is less than the effective partial pressure of the atmosphere surrounding the metal droplet after it is deposited on the substrate. The substrate should not be wet by the liquid metal which is used to form the metal microsphere and may be polymeric eg a polyimide aluminium oxide coated aluminium, or aluminium coated polyimide. In a specific embodiment the microspheres may be applied to a continuous web. The coated substrate may be used as a breadboard for testing electric circuits where an electric circuit can be formed in the array by tracing through the microsphere-coated surface with a sharp object; in soldering by placing an array against a circuit and heating the backside of the substrate whereby the individual metal microspheres melt and are transferred as solder to the circuit; or in producing images or patterns by pressing an embossed surface against the array. Tampering of security films obtained by coating such an array with a protective cover film can be observed by detecting regions of deformed spheres.
