Patent DE-3601213-A1 (DE)
Title: Haymaking machine
Inventor: PUERRER JOSEF
IPC: A01D78/12
Filed: 1986-01-17
Abstract: The swath-forming machine illustrated is connected to the tractor by means of a three-point frame fastened to the frame and is supported on the ground by means of follow-up wheels. Outward-projecting supporting arms pivotable about their longitudinal axis and having tines are fastened to a rake wheel rotatable about a carrying axle. The pivoting movement of the supporting arms is generated by control arms, on which control rollers running in a track of the control cam are seated. By means of the pivoting movement, the tines are controlled in such a way that, in a part region of their path of rotation, they rake together fodder lying on the ground and, in another part region, they deposit it as a swath. The raking together of the fodder always takes place in front of the machine, as seen in the direction of travel. To make this possible also in the event of a change in the direction of travel (rotary swath-forming machine drawn or pushed), the control cam can be rotated and be locked in different angular positions. So that this fixing of the control cam can be carried out in a simple way, the pivoting movement of the follow-up wheels, in conjunction with the levers and a push rod, is used for this purpose.
Patent DE-3603494-A1 (DE)
Title: Brake device
Inventor: DIEKMANN HANS-JUERGEN
IPC: B60T8/34
Filed: 1986-02-05
Abstract: The invention relates to a brake device for actuating an electromagnetic brake for motor vehicle trailers or the electromagnetically braked rear axle of a motor vehicle with a hydraulic/pneumatic main brake system, the vehicle deceleration caused by the main brake system being fed by way of sensors, which determine the axle and wheel speeds of rotation within a timed cycle predetermined by a gate timing pulse generator, as control variable into a computer, which actuates the electromagnetic brake with a brake current variable in its frequency and pulse to no-current ratio and thereby at the same time prevents locking of the electromagnetically braked axle. In the event of a failure of the hydraulic/pneumatic brake circuit, maximum lock-free braking of the vehicle is furthermore brought about just as in the event of any locking of the hydraulically/pneumatically braked front axle.
Patent DE-3605926-A1 (DE)
Title: Filter arrangement
Inventor: ALI AMAR DR
IPC: H03H17/02
Filed: 1986-02-25
Abstract: The invention relates to a filter arrangement consisting of two identical filters (F1, F2) having a non-linear phase characteristic, and two buffer memories (Z1, Z2). The invention is particularly suitable for filtering time-limited signal sections such as, for example, the individual lines of a video signal. Such a signal section first passes through the first filter (F1) where a group delay distortion occurs. This distorted signal section is stored in a buffer memory (Z1) and then read out again backwards in time and then supplied to the second filter (F2). The signal section is there distorted in the same manner so that the group delay distortions cancel over the entire frequency range due to the time inversion. Finally, the signal section is time-inverted again in the second buffer memory (Z2) and then passes to the output (A) of the filter arrangement. <IMAGE>

Title: Device for producing vessels or packagings by thermoforming a sheet web
Inventor: HANNIG HARALD
IPC: B29C51/42
Filed: 1986-03-14
Abstract: In a device for producing containers or packagings by thermoforming a sheet web, in which the heating is carried out via contact heater plates, the support of the sheet web in a first heating zone is to be improved. In this first heating zone, the sheet web has not yet been grasped by the conveying system at the lateral edges, so that it can freely expand. This is obtained by means of a positionally fixed metal plate on which the sheet web lies and with respect to which a lower contact heating plate can be moved. By this means, a good contact is achieved in a simple manner and facilitates the introduction of a new sheet web, does not cause any electrostatic problems and ensures uniform heating and allows the sheet web to be heated according to format in a second heating zone. <IMAGE>

Patent DE-3710325-A1 (DE)
Inventor: SOEDER CARL-JOHANNES
IPC: C02F3/00
Filed: 1987-03-28
Abstract: In an aerobic process for waste water (effluent) purification with intermittent batch feed of the waste water to the activated sludge tank from which the treated waste water is discharged continuously, the nitrate content of the waste water is simultaneously reduced by the aeration of the activated sludge tank, commencing with the flow of the waste water to the tank, being restricted to values corresponding to </= 0.5 mg/1 of dissolved oxygen, or in particular turned off, until the nitrate content in the tank has fallen below 5 mg/1 or, in particular, below l mg/1. In such treatment of communal waste waters, an approximately 1 hour cycle time is advantageous and the aeration, commencing with the rapid input of the waste water charge, is turned off for about 5 minutes. Suitable feed batches are </= 30% and, in particular, between about 5 and 20% of the tank contents. In this process, the nitrate content is reduced during the phase with oxygen restriction, while in the subsequent phase (over longer periods of time), the ammonium carried in with the waste water feed is converted into nitrate, it being advantageous to provide for an adequate nitric bacteria population in the tank.

Title: Process for the purification of waste waters contaminated by light materials, in particular saponifiable oils or fats
Inventor: WEILER WALTER DIPL ING
IPC: B01D21/00
Filed: 1987-04-14
Abstract: A novel process is described for purifying waste waters (effluents) contaminated by light materials, in particular saponifiable oils and fats (greases). In order to decrease the residual contamination, it is proposed to pass the waste water through a filter made of reticulated polyurethane foam. The dispersed or emulsified particles of light material are retained on this filter. During backwashing of the filter, which can be assisted by air, heat is used for liquefying the particles. If a web-like filter is used, this can be endlessly wound round a bottom and top reversing roll and can be moved upwards for cleaning by squeezing. During the purification, waste water, filter and squeezing roll can be heated. The filter and/or purification operation itself can be assisted by flotation.

Title: Process for producing thin superconducting films made of ceramic material
Inventor: GEERK JOCHEN DR
IPC: H01L39/24
Filed: 1987-05-11
Abstract: The invention relates to a process for producing thin superconducting films of compounds of the general formula  Mex<III>Mey<II>CuzOn,  where   Me<III> is a metal selected from the third main group or the lanthanoid group, Me<II> is a metal selected from the second main group of the periodic system of elements and   x is a decimal less than 2,   y is a decimal (2x) or less than 1 or 1,   z is 1 or 3, and   n is an integer or a decimal between 4 and 7. In the method, the elements of the compound are sputtered onto a refractory oxygen-resistant substrate in the desired atomic ratio by cathode sputtering. In the method, the elemental constituents of the desired compound present in the film are intended to condense on the substrate with the desired composition and the surface mobility of the copper is to be virtually prevented. This is achieved by combining the following process steps:   a) sputtering the metals, or the metals and oxygen, onto the cold substrate until the desired film thickness is reached at a temperature ranging from the temperature of liquid nitrogen up to 200@C, and b) conversion of the amorphous compound formed on the substrate in step a) into a superconducting structure by heating the film to a temperature ranging from 800@C to 1000@C for a time of between one second and one hour.
Patent DE-3722126-A1 (DE)
Title: Control valve
Inventor: OLEN ROBERT B
IPC: F15B13/01
Filed: 1987-07-03
Abstract: The invention relates to a control valve with a valve body with an inlet port, an outlet port and a pair of working ports, with devices for selectively connecting the inlet port to one or the other working port and the outlet port to the other respective working port. Non-return valves are connected to the working ports in order to normally prevent a flow of fluid into the working ports, e.g. from a hydraulic cylinder. Each of the working ports is connected to a control port in the non-return valve which is allocated to the other working port, specifically via a control line which is designed in the form of a bore in the valve body. When the pressure fluid is taken to the inlet port, the non-return valve which is allocated to the connected working port is opened in order to permit a flow of fluid to the hydraulic cylinder. Furthermore, a portion of the pressure fluid flows through the associated control line to the non-return valve which is connected to the other working port in order to then open this non-return valve and permit a flow of fluid from the hydraulic cylinder into the associated working port and to the connected outlet port. Each non-return valve is provided with an annular valve which has a working surface for a control signal, which working surface ... by the difference between a piston section with a larger diameter and an annular-valve section ...
