Title: Piling system for pit or slope - uses press device to place pile panels between sloping ground and guide posts
Inventor: WALTER ULRICH
IPC: E02D7/26
Filed: 1992-06-19
Abstract: One or more guide posts (4) are placed in the ground (6), and the ground is excavated to a certain depth at the post. A first pile panel (10) is positioned between the post and the slope (8) thus formed. A press device (14) is releasably connected to post and panel, so that it drives the panel into the ground. A second panel (18) is placed on the first between post and slope. The soil is excavated to a second depth to the lower edge of the first panel.

Inventor: STENZEL GERHARD DR
IPC: G07D7/20
Filed: 1992-08-20
Abstract: In order to detect security documents irrespective of their individual graphic designs, a method and apparatus are provided in which the presence of certain structural elements common to a variety of different security documents are analyzed without analyzing the whole printed image or comparing it for identity with the stored printed image. For example, the structural elements may be curved colored lines present in a certain minimum density of a surface, or intertwined line structures known as guilloches. The document to be copied is scanned as in any normal copying operation and the structural elements identified by electronic pattern recognition in order to determine whether copying is to be permitted, without requiring additional detection elements.

Abstract: An arrangement for relatively rotating the shaft (10) of an internal combustion engine with respect to the driving wheel (24) rotatively arranged on the shaft has a hydrostatic pump (21) whose housing (21A) is rotationally secured to the camshaft (10). Within the driving wheel (24) and pump (21) is located an electromagnetically actuable control valve (13, 13') which controls the hydraulic connections between the pump and the regulating device (rotary piston control) (17), i.e. puts pressure on or relieves the pressure chambers (25A to 27A, 25B to 27B), so that the camshaft is accordingly rotated with respect to the driving wheel. The electromagnet (72) of the control valve (13, 13') is actuated by means of a controller (73) influenced by sensors. The hydraulic medium is supplied to the regulating arrangement through a bore (11) in the camshaft (10). A very compact adjusting device is thus obtained for the camshaft.

Title: Packing for stuffing boxes on fittings and apparatus
Inventor: TUECKMANTEL HANS-J DIPL ING
IPC: F16J15/30
Filed: 1993-03-02
Abstract: Packing for stuffing boxes on fittings and apparatus, with a packing core ring of soft sealing material and at least two annular graphite discs of sealing graphite arranged on both sides of each side of the packing core ring. A sheet-metal ring with punched-out anchoring lugs projecting on both sides from the sheet plane is arranged between the packing core ring and the respectively adjoining annular graphite disc and between the annular graphite discs. The packing ring core is combined with the annular graphite discs and the individual annular graphite rings are combined with one another by the anchoring lugs of the sheet-metal ring, which have penetrated the soft sealing material or the sealing graphite and are bent over into these materials, to form a mechanically uniform seal. At their inside annular edge, the sheet-metal rings additionally interact as wiper elements with the shaft, the adjusting rod or the spindle of the associated fitting. <IMAGE>

Title: Self-excited potential hydrogen fusion - by dispersing hydrogen nuclei in metal lattices and maintaining by charged high energy end prod. nuclei of potential hydrogen fusion
Inventor: RAUTENHAUS HEINRICH
IPC: G21H1/02
Filed: 1993-03-11
Abstract: In hydrogen nuclear fusion in metal lattices, the fusion occurs as a self-excited potential-hydrogen-fusion (PHF) of hydrogen nuclei which are dissolved in metal lattices and which are maintained by the charged high energy end prod. nuclei of the PHF reactions. Electron showers are produced consisting of high kinetic energy electrons which induce further preferred PHF reactions. Metal pref. has an extremely large surface (pref. in foam or micro-cluster form) which is in continuous contact with hydrogen of suitable isotopic compsn. The PHF process may be initiated by bombarding with ionising radiation, passing an electric current through the metal or effecting a glow or arc discharge in the reaction space. Host metal may be subjected to periodic binding stresses in the initiation phase or during the entire reaction and is pref. highly negatively charged during the PHF reaction. ADVANTAGE - Cold fusion process does not require continual energy input once initiated, can employ normal hydrogen and has a reaction rate which can be varied. Part of the released nuclear fusion energy can be directly converted into usable electrical energy.

Title: Method for reducing interference (noise, disturbances)
Inventor: WISCHERMANN GERHARD DIPL ING
IPC: H04N5/21
Filed: 1993-06-11
Abstract: A method for reducing interference in the signal of a motion detector for recursive filtering of video signals is proposed. The signal is median-filtered, a part of the amplitude range of this signal which is situated below a threshold value is suppressed, and this is thereafter used to form the factor (k) which controls the recursive filter. In this case, for images which are stationary or move only slightly the factor (k) is set to the maximum value as a function of disturbing (spurious) pulses occurring in the video input signal (V1), or to the minimum value as a function of the disturbing pulses occurring in the video output signal (V2).
