Title: Device for monitoring a three-phase system without neutral conductor for failure of a phase
Inventor: FUHRMANN HANS DIPL ING
IPC: H02H3/253
Filed: 1983-06-01
Abstract: In this device, the object is to achieve a reliable disconnection of the electrical device only when a phase fails totally and not when there is imbalance in the load. This is done by a resistor (W1, W2, W3), a diode (D1, D2, D3) and an optocoupler (O1, O2, O3) being connected in series between in each case two phases of the three-phase system, each optocoupler supplying an L signal during a positive halfwave of the alternating voltage and an O signal during a negative halfwave, the negated output signal of each optocoupler being supplied, on the one hand, directly to the first input and, on the other hand, after delay of the rise and fall to the second input of an EXCLUSIVE OR gate (E1, E2, E3), and the outputs of the EXCLUSIVE OR gates (E1, E2, E3) being connected to the inputs of an OR gate (1), which is followed by a retriggerable timing section (2) with a time set to approximately 90 DEG  of the alternating current period. <IMAGE>

Patent DE-3331577-A1 (DE)
Title: Apparatus for cutting up and drawing off a binding tape
Inventor: HANSEN MANFRED
IPC: B65B69/00
Filed: 1983-09-01
Abstract: The invention relates to an apparatus for cutting up and drawing off a tape used to hold a bundle, having a cutting and gripping apparatus for the tape which can be brought up to the bundle. In practice, problems occur in such apparatus because the binding tape frequently becomes jammed on some part of the apparatus after severing, when it is being drawn off. The object of the invention is to design the apparatus in such a way that the binding tapes can be drawn off in a simple manner after severing. To this end, it is proposed that on the opposite side of the bundle 2, in relation to the cutting apparatus 1, a collecting cone 3 which extends transversely to the axis of the bundle be provided for the upper end of the severed tape 4 and that at least one holding down device 5 which can be swung in and which holds the tape 4 in the smallest cross-section of the collecting cone corresponding to the width of the tape, is provided. <IMAGE>
Patent DE-3334350-A1 (DE)
Title: Electronic voltage decoupling in telephone stations fed via the subscriber line
Inventor: BRANDSTETTER ALFRED DIPL ING
IPC: H04M19/08
Filed: 1983-09-22
Abstract: The invention relates to a circuit arrangement for electronic voltage isolation of AC and DC voltages in telephone stations in the feed voltage supply of telephone terminal keypads. Keypads of this type must also be fed via the subscriber line when a call is in progress, an upper voltage limit being defined. The feed voltage must be applied as quickly as possible, and the overall circuit is intended to have a high input impedance in order to identify dialling-dependent loop interruptions. To achieve this, the collector-emitter junction of a control transistor is disposed in one of the a/b wires leading to the keypad, which transistor is controlled on the base side by a differential amplifier, located between the wires, in such a way that an AC voltage applied as a speech voltage is de-activated and the DC feed voltage supplied to the keypad by a capacitor located between the wires and charged via the collector-emitter junction remains limited. The latter is achieved by the differential amplifier driving, on the one hand by a zener diode located between the wires and on the other hand by a resistance network. It can be used in any keypad with a memory.

Patent DE-3410310-A1 (DE)
Title: Three-dimensional or dissolving slide viewer
Inventor: RIMOLDI LUIGI
IPC: G03B35/20
Filed: 1984-03-21
Abstract: The invention relates to the first-time production in the smallest space, and thus portable, of images which have spatial effects by the use and interconnection of two identical, individual and converging small slide projectors. This 3-D slide viewing is done by using polarisation filters in front of the respective lens of the two slide projectors, and polarisation spectacles. This converging arrangement of the two slide projectors, which projects the beams coming from the slide to a common slanting mirror situated opposite and cause them to fall onto a light-transmitting special foil after being reflected by the mirror, even permits two different slides to be dissolved without the use of polarisation spectacles, in order to produce special light effects, pictorial representations etc., so that it is also possible to speak of a dissolving slide viewer. It can also be used as a normal slide viewer by switching off one of the two slide projectors.

Title: Circuit arrangement for monitoring the fluid level in the reservoir of a wheel-slip controlled brake system
Inventor: REINARTZ HANS-DIETER
IPC: B60T8/88
Filed: 1984-08-16
Abstract: A circuit arrangement for monitoring the fluid level in the pressure equalising and storage reservoir of a wheel-slip controlled hydraulic brake system is equipped with a single switch (2), actuated when the fluid level sinks below a response threshold, to which a pressure-controlled switch (7) and a fall-delay timed control stage (D1) are connected in series. In addition a second control stage (D2) is provided, which is switched over when the starter is operated and is maintained in this switch position by way of a contact (d21) in a self-holding arm (15) if the fluid level is adequate. If the fluid level drops below the response threshold, a brake warning light (4) is immediately switched on by way of a contact (d22) of the second control stage (D2). This fault, however, is signalled to the electronic control unit (9) by way of the fall-delay timed control stage (D1) only after a predetermined length of time, during which the driver can terminate the controlled braking, has elapsed and then leads to shutting-off of the wheel-slip control. <IMAGE>

Title: Air conditioning system for vehicles
Inventor: HOELTER HEINZ DIPL ING
IPC: B60H1/00
Filed: 1985-01-29
Abstract: It is known to control the air conditioning systems of motor vehicles automatically, specifically in dependence on a preset temperature. In addition it is known to install filters in vehicle cabs in order to keep any offensive and harmful dusts and materials away from the occupants. The air is partly lead in a circuit and, in the case of high relative humidity, does not remove the moisture in order to prevent misting of the windows. To eliminate this disadvantage it is proposed according to the invention for the air conditioning system to be controlled according to temperature and relative humidity. This can be preselected by hand or have a constantly fixed setting.
