Title: Servo drive for folding pontoon sections - has double rams with offset operation to cover dead point during folding
Inventor: BEIER GUENTER ING GRAD
IPC: E01D15/22
Filed: 1980-04-10
Abstract: The servo drive for folding pontoons has the upper pontoons hinged on the support hulls about axes (3) at the upper corners of the support hulls away from the water. The folding action is powered by two rams (2,8) on each side, linked to the axis by a short crank lever (5). The rams are offset to ensure that the dead point of each is covered by the other. This enables smaller capacity rams to be used. The ram action is controlled by automatic valves (12,13) operated by short cams (18,19) on the back ends of the ram housing.

Title: Pre-emphasis phase time constant control system - generates frequency components independently of each other and adds them together after change
Inventor: KLAV SIEGFRIED
IPC: H04B1/62
Filed: 1980-05-08
Abstract: The pre-emphasis phase system consists of a frequency independent and a frequency dependent component, the latter being changed in response to a control magnitude. The components are separately generated and the frequency dependent component is changed in response to the control magnitude only after its generation. The frequency independent and the controlled frequency dependent components are added. The circuit for the time constant control for this process comprises a setting element, whose control input receives a control signal, and an RC-element. It has two signal branches (10,20) receiving in parallel the input signal (pe). One branch (10) comprises the capacitor (C) of the RC-element and the setting element (VCA), series-connected behind the capacitor. The other signal branch (20) incorporates the resistor (R) of the RC-element. Both signal branches are connected to an input of a summation amplifier (OP).

Title: Vehicle reduced speed warning device - uses additional brake lamps with intermittent function and considerable after-glow effect
Inventor: PELS-LEUSDEN RUDOLF DIPL ING
IPC: B60Q1/52
Filed: 1980-08-16
Abstract: The warning of following vehicles about the leading vehicle speed reduction uses light-up of additional lamps, associated with the brake lamps, in case of extremely high speed reduction. The additional lamps are pref. trafficators, or any other extra lamps with high luminous output. Even the additional lamps may be operated intermittently, in order to increase the warning effect. These additional lamps may be kept on even after the braking has ceased, in order to warn vehicles further down the traffic lane about the reduction of normal speed. For the operation of the lamps is used a switch responsive to increased braking force or high speed reduction. This switch actuates the blinking relay or a time switch for the required period after braking has ceased. The function of the warning system is indicated by a control lamp on the dashboard, where also an overriding switch may be mounted.

Title: Channel rejection filter
Inventor: MAIER HARTMUT
IPC: H03H7/46
Filed: 1981-03-13
Abstract: In a double-tuned circuit channel rejection filter for the greatest possible suppression of a television signal, preferably in UHF bands IV/V, and transmission with minimum attenuation in the remaining operating frequency range, the two parallel resonance circuits, constructed in chamber design and mutually shielded by a metallic partition are connected together via a connecting line and inductively coupled to the input and output terminal, respectively. To extend the possible uses for this channel rejection filter by improving the selectivity whilst at the same time increasing the depths of the rejection notch and return loss in a simple and inexpensive manner, the resonance circuits are constructed in such a manner that the connecting line compensates for the coupling inductances even at the highest UHF frequencies and produces adequate decoupling of the two resonance circuits. For this purpose, its dimensions are selected in such a manner that it exhibits a length of a quarter of the mean operating wavelength and the amount of its capacitive impedance approximately corresponds to that of the two coupling inductances; in addition, the resonance lines of the two parallel resonance circuits in each case face the partition with their end section connected to earth and are arranged approximately perpendicular to the partition. A particularly advantageous possible use of this channel rejection filter in receiving systems consists in connecting it in parallel with a highly selective channel amplifier for amplifying the channel to be rejected in the channel rejection filter. <IMAGE>

Inventor: KANEKO YUJIRO
IPC: G03F1/88
Filed: 1981-05-26
Abstract: A method is specified for forming concentrated (thickened) images by contact exposure of a lithographic platemaking film. The contact exposure method uses a printer, a reflecting layer, the lithographic platemaking film, which is constructed from a light-sensitive layer and a transparent carrier, a transparent substrate and the original film. The application of the reflecting layer renders it possible to apply lithographic platemaking films of low contrast. The result of applying the lithographic films of low contrast is to obtain a concentrated image without impairing the image quality.
