Title: Method for transferring useful signals from which the background signal has been removed
Inventor: OELMAIER REINHARD DIPL ING
IPC: H04N5/217
Filed: 1986-07-24
Abstract: To transmit useful signals, from which the background signal has been removed, of infrared detectors of an infrared image sensor array to at least one CCD channel by means of transmitting circuits allocated to the individual IR detectors, it is proposed to irradiate the IR detectors with a reference radiation source before the useful signal is read out and to use the reference charge generated by each IR detector during this process for setting in each case an individual threshold in the transmitting circuit, by means of which, in a second step, the useful-signal charges of the IR detectors irradiated with the image to be evaluated are subtracted in accordance with the known skimming method.

Abstract: A seating unit for crew members of a vehicle, especially an aircraft, and its installation. The seating unit is fastened to a load-bearing structure and is composed of an upholstered seating surface, an upholstered back, an upholstered headrest, a safety belt system and a supporting frame. Its function is essentially to provide a seating unit where the seat and the supporting frame are movable in relationship to each other, thus leaving, in the corridor areas of a vehicle, the necessary free space for normal passage and for compliance with mandatory evacuation regulations, and at the same time ensuring the comfort and safety of a crew member using the seat. The installation of such seats is particularly advantageous in the areas from which the crew members could not have otherwise an overview of the passenger cabin. Equally advantageous is the back-to-back installation of the said seating unit.

Inventor: MIETH HANS OTTO
IPC: F16K/
Filed: 1987-01-16
Abstract: The invention relates to a method for cleaning a valve sealing arrangement under dynamic stress, and an apparatus for carrying out said method, each sealing arrangement sealing two spaces from one another by means of two seals, separated from one another, in a serial arrangement, between or in which spaces there is arranged in a moveable manner a valve part whose jacket surface interacts with the seals and thereby prevents fluids overflowing from one space to the other, an annular space, enclosing the valve part, being provided between the seals, which annular space is bounded on the outside by a housing of the valve and which is connected via at least in each case one connection and one outlet opening to the environment of the valve. The invention ensures, inter alia, that even those critical regions of the slots for the seals which can be accessed only with difficulty are reliably subjected to the cleaning agent. In terms of the method, this is achieved, inter alia, in that the seal which comes into contact with the fluid to be sealed off is supplied with cleaning fluid from the spaces on both sides of the contact surfaces, up to its contact surfaces (provided temporarily at the sealing points) with the valve part on the one hand and the housing on the other hand. The apparatus for carrying out the method is characterised, inter alia, in that each seal (70, 71) is edged in each case on its side facing the space inside the valve housing part (1 or 2) to be sealed by a fluid-permeable boundary wall (41), and in that each of the seals has a limited mobility in the direction of movement of the valve part (4). <IMAGE>

Patent DE-3722269-A1 (DE)
Title: Lifting device
Inventor: FREIMUTH ULRICH
IPC: B66F3/32
Filed: 1987-07-06
Abstract: For lifting loads, e.g. by means of fork lift trucks, hydraulic cylinders arranged in series are employed, which are connected together by lines. In order to safeguard the two hydraulic cylinders, a valve is located in the piston rod of the hydraulic cylinder which is pressurised first, by way of which the downstream hydraulic cylinder is pressurised. The valve is also designed so that damping is ensured when the hydraulic cylinder pressurised first retracts. The design of the valve provides pipe-break isolation, as well, in case the connecting line between the hydraulic cylinders is no longer functioning. In the downstream hydraulic cylinder, the stroke motion is reduced just before the limit position is reached. With a largely constant oil feed, the excess amount of oil is supplied to the hydraulic cylinder first pressurised. Since the reduction of the oil quantity is done continuously, a completely jerk-free transition is ensured. The damping of the downstream hydraulic cylinder is achieved by having a damping sleeve integrated into piston rod of this cylinder. The oil stored in the damping sleeve is returned to the hydraulic system via spiral grooves that are superimposed on the pressure-relief grooves. Sufficient independence of viscosity is achieved by the superposition of the spiral grooves and the pressure-relief grooves.

Patent DE-3832192-A1 (DE)
Title: Rope-coiling device with correction means for the rope guidance
Inventor: BROEHL ANTON
IPC: B66D1/38
Filed: 1988-09-22
Abstract: In rope-drum winches, satisfactory and uniform winding and unwinding of the rope on the rope drum must be guaranteed. For this, correction during the operation of the rope winches is necessary, often repeatedly, in the known rope-coiling devices. If deviations occur, the rope winch has to be stopped, since it is only possible to make the correction by suitable devices when the rope winch is stopped. The rope-coiling device according to the invention enables this correction to the rope guidance to be carried out in a simple manner with little design input even when the rope winch is running during the operation by virtue of the fact that the gear train between rope winch and rope-coiling device has a superimposed drive which consists of a drive unit (6) rotating with the coiling device and is fed and controlled via energy feeders such as slip rings, hydraulic or pneumatic rotary leadthrough transmissions or the like. The superimposed drive can have a drive motor (6) which is designed as an electric motor, hydraulic motor or compressed-air motor with motor brake (7). A manual drive can also be provided instead of the electric, hydraulic or air-driven drive motor. In addition, epicyclic gearing with their different drive and output possibilities offer the advantage of introducing a superimposing movement into the gear train in a simple design manner. <IMAGE>
