Patent DE-3135344-A1 (DE)
Inventor: HOFFMAN RICHARD A
IPC: C23C30/00
Filed: 1981-09-07
Abstract: The surface of a metal article which is exposed to the atmosphere and abrasion during normal use of the article is protected from scratches and/or corrosion during such use by a thin transparent abrasion-resistant film of an inert non-metallic material such as SiO2, SiC, Si3N4, TiO2, MgO, Al2O3, Ta2O5, Nb2O5, GeO2, spinel and selected colorless glass compositions. The protective film is preferably deposited by RF-sputtering techniques and undesirable coloration of the article by optical interference effects from incident light rays is avoided by properly correlating the film thickness with the refractive index of the particular material used to form the film. The invention permits the use of thinner gold plating on such items as articles of expensive jewelry and bracelets and cases for fine wristwatches without detracting from the quality, durability or appearance of the merchandise. Alternative embodiments in which several films of various selected non-metallic inert materials are combined to form composite protective coatings that provide additional cost and manufacturing advantages are also disclosed along with methods for sputter-depositing the protective films in the proper thicknesses to avoid optical discoloration effects, either on articles that have been previously plated with gold or which have been provided with a sputter-deposited layer of gold by sequentially operating the sputtering apparatus.

Title: Method and arrangement for testing the magnetic properties of a material
Inventor: GUERIN YVES
IPC: G01R33/12
Filed: 1982-02-15
Abstract: A method for testing a sample (1) of soft-magnetic material, which consists in that the sample is mounted on a holder (2) for forming a magnetic circuit which is premagnetised to a first predetermined value of remanent magnetisation (Br) with the aid of an electric pulse (6a) generated by a generator (5), which is connected to the terminals of an exciter coil with N turns on the magnetic circuit. A first electric measuring pulse (6b) is applied to the coil (3) by means of the generator (5) and a resistor (4) is used for measuring the current which is generated thereby and the measured analog value of the current is converted into a numeric value by means of a convertor (8). The change of this current as a function of time is stored in a memory (9). After that, the sample material is premagnetised to a predetermined value (-Br) with the aid of a pulse (7a) and a second measuring pulse (7b) is applied to the coil. The resultant current is measured and its numerical values are stored in the memory (9). After that, the information contained in this memory is processed further in a central unit (10) in such a manner that the permeance (A') of the magnetic circuit corresponding to the first measuring pulse, the permeance (A') corresponding to the second measuring pulse and the mean permeance (A) as a function of the magnetomotive force (Ni), generated in the coil when a current (i) flows through it, are obtained. <IMAGE>

Inventor: BERZ GERHARD
IPC: B65G57/18
Filed: 1983-05-07
Abstract: In order to avoid shaped rods P to be collected into groups or so-called "layers" climbing on top of one another in front of raisable and lowerable stopper lines consisting of stops S1, S2, S3 in transverse conveying devices 1, a method and a device are proposed by means of which the shaped rods when colliding with the stops S1, S2, S3 are kept on the conveying plane, at least in the region of the width of the largest group of rods to be collected, by means of magnetism, with increased adhesion. To this end, electromagnetic or permanent magnetic plates 2, 3, 4 are arranged so as to be aligned with one another underneath the conveying plane F, as shown in Figure 1, in sections transversely to the conveying direction R, in such a way that the magnetic flux between the north and south poles of the magnet plates is closed via the corresponding longitudinal sections of the shaped rods P as yokes. The stops S1, S2, S3 can be raised and lowered via adjustment means V1, V2, V3 and the distances of the magnetic plates 2, 3, 4 from the conveying plane can be set by means of raising means H1, H2, H3. <IMAGE>

Patent DE-3320931-A1 (DE)
Title: Composite profile
IPC: E06B3/273
Filed: 1983-06-09
Abstract: In this composite profile, which is constructed from at least two profiled parts 10, preferably consisting of aluminium, and a profiled rail 16, consisting of a thermoplastic synthetic material, a current is passed through the elements 22 in each case for a short time with interruptions, while a limb 18 is being pressed over compression elements 22, so that the profile 10 is locally heated in the manner of resistance welding. The limb 18 is constructed with knurling 20 on the inside. The influence of the current heats the profile 10, which in turn entails welding-on or softening of the profiled rail 16 at the point at which the knurling is pressed into the rail. This results in an adequate positive lock between the profiled parts, which results in a high shear strength of the composite profile. <IMAGE>

Patent DE-3338304-A1 (DE)
Title: Microelectronic level control for continuously controllable drives
Inventor: WIEWELHOVE WERNER DR ING
IPC: G05D15/01
Filed: 1983-10-21
Abstract: In the past, it was necessary to detect the level height using costly analogue movement sensors for level control for continuously controllable drives. Said sensors are to some extent difficult to accommodate and are rarely easy to operate. The measurement signal is used either simply in direct inverse proportion for the drive control, or the desired-value deviation is determined from it with the aid of a continuous controller. The adjustment step magnitude for the drive is then determined from this deviation. Using the novel microelectronic controller, it is possible to achieve the worthwhile aim of a synchronisation state at the desired level height even without analogue movement sensors and without the normal control units. The level height is determined using only a single switching sensor. Using its special program, the controller now tracks the time behaviour of the level and derives the necessary adjustment steps from said behaviour. Synchronisation at the desired height is achieved even after a short time. As a result of its control behaviour, all disturbance variables are compensated for directly and completely, as was possible in the past only by using continuous controllers. Since the program is universally valid and the position of the characteristic can be influenced as desired at any time by external parameter settings, virtually all level control tasks can be optimally addressed using this apparatus.
