Title: Vehicle engine silencer exhaust gas cooler - has integrated gas conversion unit esp. thermal reactor
Inventor: LEISTRITZ HANS KARL DR
IPC: F01N3/26
Filed: 1977-04-14
Abstract: The cylinder exhaust pipes (9) of a combustion engine lead to an expansion area (10). From this area it flows directly into a silencer, alternatively, it flows into a silencer after flowing through an intermediate space which is mounted in the silencer. The gas flow pipes in which the cooled exhaust flows, leads the gas to a gas converter esp. a thermal reactor. The first expansion area from which untreated gas is fed to the cooling unit has a heat exchanger wall common with the hottest area of the after burner chamber.

Title: Rotating shutter connected to gas spring piston - varies effective pressure compensation cross=section, with adjustment by connecting rod rotation
Inventor: HOLZER WALTER
IPC: F16F9/44
Filed: 1977-05-21
Abstract: A gas spring comprises a pressure-loaded cylinder, a piston with a pressure compensation aperture and a connecting rod guided outwards and joined to the piston. A shutter is connected to the piston and is adjustable, having also a pressure compensation aperture which is rotatable relatively to the piston aperture around the cylinder lengthways axis. When the shutter is rotated, the effective aperture cross-section is varied, so that the adjustment of the two pressure compensation apertures in relation to each other is achieved by rotation of the connecting rod. At least one of the pressure compensation holes is formed as a spiral with varying radius and cross-section, and the adjustable shutter supports via a friction coupling on the cylinder inner wall.

Title: Dual path distance measurement system - uses supplementary measurement signals with slightly different carrier frequencies for high accuracy
Inventor: HOEFGEN GUENTER DR ING
IPC: G01S13/78
Filed: 1977-10-18
Abstract: A dual path distance measurement system has an interrogation station transmitting twin-pulse signals with carrier wave having a first h.f. and a responder station transmitting twin pulse response signals with a carrier having second h.f.

Title: Fail=safe logic with two AND=gates - has output of one gate returned to input connected to pulse generator
Inventor: DUEMMEN PAUL LUDWIG DIPL ING
IPC: H03K19/007
Filed: 1978-04-25
Abstract: The logic circuit produces a programmed signal with delayed decay time. It is designed so that if a component fails the delayed decay time is only shortened or disappears. A fail-safe AND-gate is connected to fail-safe AND-gate with a negated input such that the input of the AND-gate receiving the input signal is connected to one input of the negated-input AND-gate. The output of the latter AND-gate is fed back to that input of the AND-gate that receives the clock signals. The output of the AND-gate is connected via a growth OR-gate to a growth input at the negated-input AND-gate. Both AND-gates have capacitors to maintain a time-limited control potential.

Title: Rolled metal sheet end edge trimmer - has two TV cameras focussed on edges to display pictures on screens at control station
Inventor: BURGSMUELLER WERNER ING GRAD
IPC: B23D36/00
Filed: 1978-05-30
Abstract: Metal sheets leave the rolling mill with irregular end edges which have to becut square with the sides by a shears (1). Since the sheets may be at a temperature of 400 deg.C to 700 deg.C it is difficult to determine the shearing line necessary to reduce the size of the off-cuts to a minimum. This difficulty is overcome by using two TV cameras (2) (3) which transmit pictures of the irregular edges to TV screens (7) (8). These pictures enables the operator to adjust the position of te sheet w.r.t. the shear blade to achieve the desired result.

Title: Ringing-current and loop-current supply system - uses four current sources simultaneously supplying ringing currents to both legs to reduce harmonics
Inventor: DRAGOTINOV ALEXANDER DIPL ING
IPC: H04M19/02
Filed: 1978-08-14
Abstract: The ringing-current and loop current supply system keeps the ringing current esp. low in harmonic content despite relatively large variations in the lengths of subscriber lines. The ringing current contains no d.c. component. All four current sources simultaneously supply their ringing currents to both legs at least during a part of the duration of the ringing pulses. The resulting amplitudes of these superimposed ringing pulses during each part of the duration are smaller than the sum of the magnitudes of the first and second instantaneous amplitudes. No coils, relay contacts, or transformers are used which eases integration.

Title: Gasification of solid fuels - using a vibration mill as reactor to simplify process and increase output
Inventor: GARSTKA JOHANNES DR ING
IPC: C10J3/00
Filed: 1979-02-13
Abstract: Gastification of solid fuel is carried out in a vibration mill during the milling process, with the gasifying agent (air, O2, steam or CO2) passed through in countercurrent to the fuel (e.g. coal). The process is simplified by a redn. in the number of stages and amount of equipment. The mechanical action increases the reactivity of the coal, allowing a reduction in gasification temp. and requirement of O2 and steam, giving product gas contg. less inert gas. The counter-current gas flow allows the heat of the product gas to be used directly to pre-heat the coal, which also removes dust from the gas. Reduced slag formation leads to a stabilised process, and eases the generator lining problem. By circulating the milling bodies as heat carriers, amount of O2 and/or air to maintain the process temp. is reduced.
