Title: Fuse holder system with indicator - applies earth by user's finger to light that indicates fuse condition
Inventor: OHLSSON SUNE
IPC: H01H85/32
Filed: 1978-02-22
Abstract: The fuse holder has an indicator showing whether the fuse has cut out or not. The end (2b) of the fuse (2) not connected directly to the supply voltage is connected to an indicating device which can be activated so that it emits an optical signal if a voltage is present at the non-supply end of the fuse -- i.e. if the fuse has not cut out. Activation is via a switch that applies earth to one end of the optical indicator. This switch is formed by the user's finger placed on a touch plate. The earth connection is through the user's body.

Patent DE-2835491-A1 (DE)
Inventor: KAISER MANFRED DIPL PHYS
IPC: H04B10/07
Filed: 1978-08-12
Abstract: A beam splitter is required in order to separate the light backscattered or reflected in the optical fibre to be measured from the light coupled into the optical fibre. In the arrangement according to the invention, an end face, obliquely faceted at a specific angle, of an optical fibre which is coupled to the optical fibre (7) to be measured is used as beam splitter (4). The disturbing influence of reflection at the fibre input is thus eliminated, and it is possible to measure different characteristics in transmission or reflection or backscattering without reequipping the measuring arrangement. <IMAGE>

Title: Swing window leaf pivot - has intermediate element between frame and leaf sections with elastic strips sealing gaps
Inventor: LAHMANN ERNST
IPC: E05D7/082
Filed: 1978-12-19
Abstract: The leaf pivotal point consists of a frame section and a leaf section connected by hinge assembly with an intermediate section (4). The frame section consists of extruded profile (7), the leaf section of profile (8). The frame section is covered on the outside by profile (10) and profile (11) covers the leaf section from the inside. The outer gap between frame sections (7, 8) are sealed by lip-shaped strips (15) fitted in grooves. The lips work together with the flange parts of the frame sections (2, 3). Should the sealing on the outside fail for some reason, the sealing strip between the intermediate element (4) and frame section (2, 3) prevents the entry of any air current into the room. This is made possible by arranging the strip as near as possible to the surface (13) facing the room.
Patent DE-2856756-A1 (DE)
Inventor: GIGER URS
IPC: G04C23/08
Filed: 1978-12-29
Abstract: In the quartz watch according to the invention all the time displaying hands (of the hours, the minutes and, possibly, the seconds) are kinematically permanently connected to each other, so that their relative positions are precisely fixed, whatever manipulations are made by the user. As shown, the rotor 7 of a stepping motor drives seconds wheel 16 driving a wheel 20 (on the minutes hand shaft 23) driving hour wheel 28. A clutch may be provided between the rotor and the seconds wheel. Pulling out a stem 64 to a hand setting position energises automatic hand setting control circuitry having a detector sensitive to the manually controlled displacements of the hands and a counting device for finishing off these displacements and for memorizing the time impulses during the manual correction. The arrangement ensures automatic setting of the hands in the exact time indicating positions, thus permitting a user who travels from one time zone to another to make rapidly the necessary manual adjustment without prejudice to the previous precision of the time indication. Accurate setting of a seconds hand may also be provided. <IMAGE>

Title: Address-less fault location for digital transmission systems - uses transmission of identical fault locating signals with same sign by testing end stage, affecting loop formation on output lines
Inventor: DRULLMANN RAINER DIPL ING
IPC: H04B17/40
Filed: 1979-02-03
Abstract: The addressless fault localizing process for digital transmission operates with intermediate stations, which contain regenerators in the separate transmission lines and loop forming devices from the one to the opposite direction of transmission. A testing terminal station transmits fault local signals along the outgoing transmission line. The terminal station transmits only like fault locating signals with the same characteristic sign. These signals effect progressively on the outgoing transmission line both the loop formation and are used in the terminal station to detect faults or to locate the fault. At the beginning of the fault location, during the first fault locating signal transmission, a counting station for each regenerator of the outgoing transmission direction is trigerred. This system requires little instrumentation and is simple.
