Title: Galvanic secondary cell containing an organic electrolyte
Inventor: VOSS ERNST DR
IPC: H01M4/48
Filed: 1982-12-03
Abstract: As a result of using Li-doped polyacetylene (PA) as the negative electrode of a galvanic Li/CrOx cell, this electrode becomes quasi-metal-free, with the result that troublesome Li dendrite formation does not occur and the cell functions perfectly as a secondary cell. On the basis of the general conversion equation <IMAGE> its high theoretical energy density ED depends essentially on the degree of doping y (c.f. figure). For a cell voltage Uo = 2.6 V and F = 26.8 Ah, the relationship   DOLLAR F2  yields 491 Wh/kg for ED with, for example, y = 0.18 and x = 1. Suitable electrolyte solvents are preferably cyclic ethers such as methyl-substituted tetrahydrofuran or dioxane.

Patent DE-3323179-A1 (DE)
Title: Process and device for rendering sheet glass matt
Inventor: FLOETENMEYER MAX
IPC: C03C17/30
Filed: 1983-06-28
Abstract: The invention relates to a process and a device for rendering sheet glass matt. While sheet glass is rendered matt in a conventional manner in a sand blaster or is treated with hydrofluoric acid in a complex acid-treatment zone, the invention provides that the sheet glass is repolished after treatment with the finely particulate agent and the surface is then treated with a transparent plastic which has a similar light refraction exponent to the glass, by rubbing the plastic in, and polishing the surface until the sheet glass becomes clear. In this way, a virtually clear glass is obtained in which directed reflection no longer occurs. Furthermore, the costs for the treatment equipment and material machining are considerably lower than in known devices, such as acid-treatment units. The finely particulate agent need not be just a blasting agent in a jet with a fluid, but may also be a glass powder which is sintered at about 200 DEG C by means of an infra-red lamp after the coating. The coating can also be applied by screen printing.

Title: Safety fitting with pressure reducer and backflow preventer
Inventor: HECKING WILLI
IPC: E03C1/10
Filed: 1983-08-23
Abstract: A safety fitting with pressure reducer and backflow preventer is constructed in such a way that the valve disc (30) of the pressure reducer is displaceable on the valve spindle (32) against a spring (34) up to a stop (38). Consequently, the pressure-reducing valve (30, 24) at the same time acts as a backflow preventer. In an advantageous design of a safety valve, the diaphragm disc (64) has a safety-valve seat (66) which is held in contact with a safety-valve seat (68) not only by the load spring (70) of the pressure reducer but also by a second load spring (72) supported on the valve spindle (32). During a pressure rise after closing of the pressure-reducing valve, the additional load spring (72) is overcome and the safety valve (66, 68) opens. <IMAGE>

Title: Safety device for a starter circuit
Inventor: ULLMANN RUDOLF
IPC: G01R31/02
Filed: 1983-12-14
Abstract: Starter cables which must be passed over vehicle parts which move with respect to one another, for example the articulated area of an articulated vehicle, are subject to particular mechanical wear and the risk of a contact of the conductor flex of the starter cable with the vehicle earth is particularly great when the insulation is damaged. Due to a high current load and a lack of spare battery power during starting, fuses cannot be used in the starter circuit. The stressed section of the starter cable is surrounded by a protective conductor which, in turn, is again surrounded by electrical insulation. Thus, the protective conductor is insulated both against contact with the vehicle earth and with the conductor of the starter cable. An electrical monitoring circuit can be used for checking whether a current flow is possible via the protective conductor and an electrical signal device due to damage to the insulation. When the signal device responds, short circuits having severe consequences can be avoided if the starter cable section is immediately replaced.
