Patent DE-3624291-A1 (DE)
Title: Fresh air fan for vehicles
Inventor: HETTICH VOLKER
IPC: B60H1/00
Filed: 1986-07-18
Abstract: An electric fresh air fan for vehicles, especially for motor vehicles, is proposed which have an enclosed or closable inside passenger compartment. A fan unit (10) which is connected to a solar cell unit (27) for power supply ensures, even when the vehicle is parked, that there is a permanent supply of fresh air and/or air circulation to make it possible to prevent heating of the inside passenger compartment. Excessive heating can therefore not occur in the inside passenger compartment even when the vehicle has been parked in the sun for a relatively long period, without giving rise to operating costs or running down the battery. <IMAGE>

Abstract: A transformer arrangement (2) is specified for coupling a first AC voltage system (R, Y, B) having M phases to a second AC voltage system (P1-P5) having N phases, in the case of which transformer arrangement (2), even in the event of a load which is not sinusoidal but is identical for all the phases (P1...P5) on the secondary side, the current harmonic content on the primary side is reduced and the real load is distributed in a balanced manner between all the primary phases. In this case, M >/= 2, N > 3 and, at the same time, N NOTEQUAL  n x M, n >/= 1, as integers. The phase angle  phi  between 2 phases on the secondary side during the formation of a network coupling is selected to be  phi  = (f1-f2) x 360@/f2, and N = f2/(f1-f2). In this case, f1 is the frequency (60 Hz) of the first AC voltage system and f2 is the lower frequency of the second AC voltage system. The phases (P1...P5) on the secondary side are connected via 3 converters (3-5), which have AC switches (S1-S10) in their bridge arms, to primary windings (a, b, c) of an output transformer (6) whose secondary windings are connected to phase conductors (U, V, W) of the AC voltage system whose frequency is f2. The multiphase transformer arrangement (2) may consist of a multiphase transformer and possibly, in addition, 2 single-phase transformers. The turns ratios of the transformer windings are specified. <IMAGE>

IPC: B65H3/48
Filed: 1986-12-22
Abstract: At the removal side of a sheet stack (2, 12) there are arranged a suction drum (3, 10) and a strip (4, 11). The strip (4, 11) is assigned to the front end region of the sheets to be separated and is movable in the vertical direction of the sheet stack. The strip (4, 11) which increases the suction action of the suction drum (3, 10) by virtue of its bearing against the sheet stack (2, 12) delimits the suction region of the suction drum (3, 10) against uncontrolled flowing in of leakage air. By virtue of the provision of a certain clearance "A" between the suction drum (3, 10) and the strip (4, 11) a controlled inflow direction of the leakage air at a point not influencing the separation process is ensured. An end wall of a supply magazine (1) for the sheet stack (2, 12) is provided with a recess in which the strip (4, 11) can be immersed and by means of which a controlled proportion of leakage air can flow to assist the sheet separation at the stack front side. <IMAGE>

Title: Control unit
Inventor: LOECK HARALD DIPL ING
IPC: F02D41/14
Filed: 1987-04-29
Abstract: A unit for controlling a fuel supply system of an internal combustion engine (1) is described. This unit has a revolutions counter (8) which records the speed of the internal combustion engine and a lambda  probe (9) which determines the actual value of the fuel/air ratio from the oxygen content of the exhaust gases of the internal combustion engine, and also a signal generator for generating a fuel metering signal which is dependent on a desired/actual comparison between the actual value of the fuel/air ratio and a desired value of the fuel/air ratio which can be taken from a memory as a function of the measured speed value and on an air quantity value. To reduce the cost of this control unit and increase its precision, the intention is for it to be possible for the air quantity value to be determined from the actual value of the fuel/air ratio and from the fed-back fuel metering signal in a computing unit. <IMAGE>

Title: Leakage detecting system
Inventor: GAWINSKI HUBERTUS DIPL ING
IPC: G01M3/00
Filed: 1987-07-29
Abstract: The invention relates to a method for finding leaks on inflatable bodies by means of a thermal effect. In order to locate leaks using a method which is quick and can be automated, it is proposed that the test specimen (piece) is introduced into a chamber in which the temperature and thermal radiation are everywhere the same, that the thermal radiation of the inflated test specimen is measured with high resolution, and that any possible points on the surface of the test specimen which have a reduced thermal radiation are located as leaks on the thermal image thus produced. By taking two measurements in quick succession at different air pressures, the requirements placed on the test chamber can be substantially lowered.

Title: Pipe piece for introduction into a pipeline which can be closed at both ends
Inventor: HEYNE ANTON
IPC: F16L55/035
Filed: 1987-12-23
Abstract: In the case of water-safeguarding systems, the pipelines of which can be closed at both ends and which exhibit a manually actuable valve which has a so-called displacement screwing arrangement, there is the danger that the quantity of water displaced upon closing the manually actuable valve builds up a harmful pressure with respect to the switchable safety valve. The superatmospheric dynamic pressure damages such valves. The abovedescribed danger is avoided in that the pipe piece has, in its inner walls, compensation space which is sealed by means of an elastic pipe body with respect to the flow space and whose volume is defined by the maximum reduction volume. <IMAGE>
