Title: Magnetic tape recorder - with tape transported on two spools in two directions has belt drive with common flexible belt
IPC: G11B15/60
Filed: 1975-04-16
Abstract: On both sides of the transmitting heads there are driving pulleys which are driven from the driving shaft of the main drive via a belt drive with a common flexible belt in such a way that the belt runs in the direction of the tape from the driving shaft to the front driving pulley, thence to the rear driving pulley and from there back to the driving shaft. As a result of the belt tension increasing from the front to the rear driving pulley, the rear pulley is forced to drive the belt more quickly than the front pulley, so that the tape has a constant tape tension at the transmitting heads between the driving pulleys.

Patent NL-7506052-A (NL)
IPC: H01J29/92
Filed: 1975-05-22
Abstract: An electrode structure includes a pin that extends through a hole in a fragile substrate, such as a thin, glass plate, and makes contact with a conductive layer on one surface of the plate. The structure includes a first metallic adherent layer on that portion of the conductive layer and a second metal layer on the exposed surface of the first metal layer. The hole extends through the conductive layer and both of the metal layers. The first metal layer is adherent to the conductive layer and consists of iron, chromium, or nickel, for example, deposited on the conductive layer. The second metal layer is a fixative for the first layer and is wettable by soft solder. It consists of a noble metal from the group consisting of gold, silver, platinum and paladium. The pin has a head larger than the cross-section of the hole and a surface that is wettable by soft solder. A ring of soft solder encircles the pin and is solidified into joining relationship between the surface of the pin and the adjacent surrounding surface of the second metal layer to form a hermetic seal and an electrical connection between the pin and the second metal layer. The solder ring may be placed on the pin as a separate element, and its temperature may be raised to the molten state by heat treatment of the entire assembly, after which the solder resolidifies upon cooling.

Abstract: 1514317 Homogenizing or refining glass SAINT-GOBAIN INDUSTRIES 11 Aug 1975 [14 Aug 1974] 33381/75 Heading C1M Molten glass is homogenized and/or refined by heating the glass so that its viscosity is not more than 1000 poises, foaming the molten glass to a volume at least 1À5 times its original volume, and maintaining the viscosity at not more than 1000 poises until the foam collapses. Preferably the glass is foamed by a gas-generating agent (e.g. Na 2 SO 4 ), the molten glass being heated at at least 20‹C. per minute. The foaming may be aided by ultrasonic vibrations. Preferably, solid vitrifiable material in granular or agglomerated form is passed to inclined duct 14 via furnace 13, in each of which the material is melted by burners 20 and 21. Gases from burners 20. 21 pre-heat the solid material in heat exchanger 23. Furnace 13 and duct 14 are cooled through tubes 17. The molten material formed is passed to channel 1 formed of Pt-Rh alloy, and surrounded by alumina insulation material 12. 12a. The molten material is heated, by Pt-Rh electrode 2 (which may be water-cooled) and by Pt-Rh immersed resistance electrode 10, at at least 20‹C./minute so that the molten glass is foamed and collapses before being delivered through tube 6. In a preferred embodiment granules are heated to 1300‹C. in 6 minutes, from 1300‹C. to 1500‹C. at 30‹C./minute, and held at 1500‹C. for about 10 minutes. In an alternative embodiment (Figures 3 and 4, not shown) the channel is supplied with molybdenum electrodes.
