Title: Polarised repeating coil for telephone lines - has improved magnetisation and return loss characteristics using diode bridge feed
Inventor: HAHN WALTER
IPC: H04B3/44
Filed: 1975-09-11
Abstract: The repeating coil circuit for coupling a branch extension with an exchange provides improved return-loss damping and reduction in number of bulky and expensive components. On the extension side of the repeating coils (N) the local DC supply is applied through balancing resistors (R1-2) across a blocking capacitor (C3) connected at the mid-point of the windings (W5-6). At the exchange side of the coils (A) only a single winding is used (W7) which is connected across a diode bridge (GL). The opposite arms of the bridge (g3) (g4) are connected to the line (a') (b'). DC current flowing in the line, through the action of the diode bridge, flows through the winding (W7) in one direction only, improving the initial magnetisation of the repeating coil.

Title: Coordinate inspection machine test probe setting - is determined by inspecting standard workpiece and deriving probe position transformation equations from result
Inventor: FROHNE HEINRICH PROF DR ING
IPC: G01B21/04
Filed: 1976-03-11
Abstract: A method is used for setting the appropriate information concerning a test probe into a computer numerically controlled, coordinate measurement inspection machine. A standard workpiece inspection is used from which an appropriate set of transformation equations can be automatically derived. Basically, when a test probe of such a machine is changed for any reason, a standard test piece of known dimensions is first inspected. This inspection proceeds automatically under the control of a subprogram which derives from the results of a set of transformation equations. These are stored in the main measurement program and affect subsequent measurement data derived from the workpieces being inspected. Several standard test pieces may be used at different points on the machine where appropriate and some machine error compensation can be achieved by this means.

IPC: G21C13/04
Filed: 1976-08-12
Abstract: A bottom for a large vessel, designed for high and variable temps., consists of several elements of high temp-resistant material held together by an external support. The elements of the vessel bottom are mounted on roller bearings, the rolling planes of which are inclined downwards toward the support point and/or to a fixed point.

Title: Stator magnetic flux measurement in three phase machines - using winding on special lamination embedded in stator of machine
Inventor: KRZYMINSKI LEON DR ING
IPC: G01R31/34
Filed: 1976-12-07
Abstract: A method of measuring the magnetic flux in the stator of a thin phase electric machine uses an auxiliary ring shaped lamination with its own auxiliary winding embedded in the stator of the machine. The specialized lamination of the measurement device consists of a ring shaped core (2) carrying yokes (3) which match the remaining stator laminations (1). An auxiliary winding (4) is wound round the outer section of this lamination using a ring shaped cavity left in the stator for this purpose.

Title: Mounting and tensioning filter sleeves - having hooked hanger which slots into lattice
Inventor: BAUR JAN VOM
IPC: B01D46/02
Filed: 1977-02-09
Abstract: Mounting and tensioning the end of a sleeve in an opening is esp. for a filter sleeve to be mounted in the openings of a lattice structure. The end of the sleeve has a hook type hanger the otuer edges of which lodge under the edges of a lattice when rotated. They are held by the tensile force of the sleeve and thus mounted. The hanger has one or more hooked ends. It has spring type properties or includes a spring. By this means it ensures good mounting and imparts additional tension to the sleeve. Instead of the lattice, a frame, cross beam or perforated plate can be used. Also leaf or coil springs are alternatives. System described permits sleeves with either a support basket or mounting ring. It permits installation from either end of the sleeve.
Patent DE-2706760-A1 (DE)
Inventor: GASS ERNST DIPL ING
IPC: H01C10/30
Filed: 1977-02-17
Abstract: In order to damp the vibrations of the slider (10b) in a current collector arrangement with a relative movement between the slider and the track, a central portion of the slider (10b) is provided with a coating (12) made from an elastomer having internal friction. Elastomers of this type are silicone rubber or polyurethane. This serves to damp the vibrations (28) of the slider (10b), which are instigated by unevennesses of the track. This measure is particularly advantageous in the case of potentiometers, because the spring force is reduced and the friction on the resistive layer is thus diminished. The service life of such potentiometers is thus increased. <IMAGE>
