Patent DE-2531374-A1 (DE)
Title: Cardan system with telescopic shafts between universal joints - has auxiliary telescopic arrangement to facilitate assembly
Inventor: KRONE BERNARD
IPC: F16D3/06
Filed: 1975-07-14
Abstract: Cardan system comprises a solid shaft connected to a first universal joint and telescopically engaging a tubular shaft through a torque-transmitting ball connection permitting axial sliding motion. The tubular shaft is in turn connected to a second universal joint. The system is enclosed by a fixed protective covering including bellows accommodating the axial sliding of the shafts. The tubular shaft comprises inner and outer telescopic tubes connected relatively tightly so as not normally to participate in the relative axial motion of the system but to facilitate assembly and provide axial motion in an emergency.

Title: Multi-wire coil spring with helical cover coil - has core wire axially fixed to prevent dislocation
Inventor: ROEHRS WERNER DR
IPC: F16F1/04
Filed: 1975-07-16
Abstract: A coil spring which is made from several wire strands, has a core wire that is enclosed by helical wire strands. Since there is the tendency for relative axial movement between the core wire and the helical strands when the spring is flexing, the protruding ends of the core are bent to form a hook. The core hooks are such that they do not increase the space requirement of the multi-wire coil spring. By fixing the core and the outside layer of the spring relative to each other, it is also ensured that the spring characteristic does not change.

Patent DE-2541587-A1 (DE)
Title: Labels for board on which tools are hung - are based on square module for orderly arrangement with silhouettes representing type of tool
Inventor: KUSS JOACHIM
IPC: B25H3/04
Filed: 1975-09-18
Abstract: The storage system for tools is based on a square module which is arranged up in a standardised manner. The storage pigeon holes which are formed are closed by labels which are squares or rectangles, composed of several modules. Each label would bear the silhouettes of a group of tools. The whole board space is used (by the labels, not necessarily by the silhouettes or tools). Possible rearrangements are easier to identify and execute than if labels of irregular size were allowed. If the new labels are numbered in an orderly fashion, it becomes simpler to give an exact description of the position of any tool on the board.

Title: Exhaust gas purification equipment for engines, and gas turbines - has separate furnace, combustion equipment and waste heat recovery
Inventor: PAULI BALDUIN DR
IPC: F01N3/18
Filed: 1975-10-25
Abstract: The equipment for purifying the exhaust gas from IC engines or gas turbines has a duct (2) leading the gas directly from the engine (1) to an afterburner (3) in a separate combustion chamber (4). The burner has a metering swirler to vary the flow of gas automatically with its temp. and oxygen content and a fuel supply controlled so that the combustion chamber temp. remains at about 800 deg.C. On completion of combustion the gas flows through a waste heat steam generator (5) where its temp. is reduced to about 160 deg.C into an exhaust to atmosphere (6). A bypass system allows the afterburner to be short-circuited in the event of malfunction.

Title: Radar signal processor for echo signal deviation reduction - uses intermediate frequency sampling circuit containing capacitors and buffer
Inventor: ANDERSON GEORGE MAIR
IPC: G01S7/292
Filed: 1975-12-18
Abstract: A radar signal processing device is designed for reduction of the magnitude of the apparent relative variation between the returned signals and a range defined as the nominal for return signals. It contains units for analysis of a received echo-signal over a number of successive intervals, displays for showing the echo signal for each interval, and further displays showing successive filtered versions of the received echo-signals. The echo signal is successively applied to a number of capacitors via a smoothing circuit and the capacitor outputs fed to a buffer. Store in a time series related to the intervals of analysis. The interval repetition rate is faster than the scanning rate but slower than the radar pulse repetition rate.

Abstract: The template or gauge is used for making expansion joints in concrete surfacings, with joint rails engaging with cut-outs in the rail retainers on a rail-accommodating cornice, the whole being locked together as a non-slipping entity. The joint rails are notched out of line at certain points, and lock into the rail retainers on the accommodating cornice. The points of notching may be pointed, round or angled. This system holds firmly when the concrete is applied, needing no laborious realignment. Three different thicknesses of concrete surfacing can be made, using only one size of rail-accommodating cornice.

Title: Magnetically supported track vehicle lateral guide system - with return force ratio more rigid in slow travel sectors
Inventor: HOLTZ JOACHIM PROF DR ING
IPC: B60L13/04
Filed: 1976-03-12
Abstract: The track-bound hover vehicle has a guiding device for generation of return forces in the event of lateral deflections, with the rigidity of this relationship influencing the vehicle drive characteristics. This ratio is proportioned so that it is more rigid in a sector to be traversed slowly than in one to be traversed at constant or increasing speed. Where there is a coreless linear motor, with a chain of rectangular superconductive exciter coils (2) in the vehicle (3), and closed-8-shaped guide coils (1) in the track (4) with inner lengthways conductors intersecting so that they are mutually insulated, the interval of the inner conductors is greater on slow travel sectors than on open sectors.

Title: Fading in circuit for symbols on TV screen - blanks colour signals and clamps luminance signal at selected level before fade in
Inventor: MATTHIES KARL-HEINZ ING GRAD
IPC: H04N9/64
Filed: 1976-04-28
Abstract: The circuit is inserted between the output of a colour demodulator with a G-Y matrix and the input of an RGB matrix. A blanking signal is applied to it during the required line length and for the required number of lines. It blocks the normal signal path, blanks the luminance signal and clamps it at a certain black value. A suitable fading-in signal is supplied to each colour channel behind the blocking circuit. Cathode-anode path of a diode, followed by base-emitter path of a transistor operating as transformer, are inserted in each colour signal path in the normal transmission direction. The blanking signal is applied through a series resistor to the diode cathode, and to a circuit for blanking and clamping of the luminance signal. The signal to be faded-in is applied through a series resistor to the base of a corresponding transistor.
