Patent DE-2744026-A1 (DE)
Title: Waste disposal system - by mixing municipal refuse with sewage sludge for a composting process
Inventor: HACHENEY WILFRIED DIPL ING
IPC: C05F7/00
Filed: 1977-09-30
Abstract: A system for the disposal of liquid, solid and toxic waste, e.g. refuse and sewage sludge, requires no dewatering plant. Refuse and sludge are mixed in such proportions that the moisture content reaches 50-55%. This mixture is turned into compost by dynamic and/or static rotting. The result is a very economical method of waste disposal. The expensive dewatering and digesting installations for sludge are saved and the ecological efficiency is raised.

Title: Fast starting system for static inverter - applies extra triggering pulses to turn thyristors in commutating circuits OFF
Inventor: KROWORSCH HANS-PETER DIPL ING
IPC: H02M7/515
Filed: 1977-10-19
Abstract: The fast starting system, is designed for use with a static inverter. It has a switching unit controlled by a start circuit and blocking or passing triggering pulses to the main and the turn-off thyristors. On receipt of a start command the switching unit applies triggering pulses from the triggering pulse generator that is already running to the main thyristors and to the turn-off thyristors and in addition passes an extra triggering pulse to the turn-off thyristor in the commutating circuit for the main thyristor lying in the same limb of the bridge opposite with the main thyristor already turned on.

Title: Contactless measurement of velocity - using lens and two arrays of optical fibres providing optical signals activating two detectors alternately
Inventor: GREENWOOD JOHN CHRISTOPHER
IPC: G01P3/36
Filed: 1978-03-04
Abstract: A contactless velocity measurement transducer derives optical signals from a moving surface of which the velocity is to be measured to activate alternately two photosensitive detectors. The output signals from these are used to represent the surface velocity. The device may typically be used to measure the velocity of a road surface w.r.t. a vehicle passing over it. Basically, the moving surface reflects or directs an irregular sequence of signals via a lens or receiver unit on to two arrays of optical fibres which are intertwined with each other so that the two photosensitive detectors associated with the two arrays, receive alternate signals from each light signal received. The frequency of the combined output signal from the two detectors represent the measured velocity. The light conductor may be constructed in a convenient etched surface format.

Title: Monitoring system for the functioning of an appts. - sets time limits for transition between two measurable valves
Inventor: GLASMACHER PETER DIPL ING
IPC: D06F34/08
Filed: 1978-04-26
Abstract: Monitoring the functioning of an appts. having a control circuit for >=1 parameter, and in which the parameter in question can be measured at >=2 points during its alteration over a period of time, sets for the value influencing the parameter in question, a max. interval of time for the alteration from the one value to the other. This interval corresponds in particular to the max. interval of time during which the alteration of the parameter from a first detectable value to the second detectable value must take place under the most unfavourable, tolerable conditions. When this interval of time has elapsed a signal is generated or the appts. is put out of action. Technique is used e.g. for the control of a washing machine for monitoring the feed of the water and its pumping away, the heating of the machine and the running of the motor, etc. Turning on the feed water or starting the pump may be used to energise a timer, the number of the impulses of which are constantly compared with the present value and related to the presence or absence of signals from the water level detectors.

Title: Continuous induction furnace for heating metal blocks - which are transported through induction coil by driven endless cables
Inventor: STENGEL EDGAR
IPC: C21D9/00
Filed: 1978-10-18
Abstract: Blocks are transported through the furnace via carriers located on endless cables which travel through the induction coil; and the cables pass through fluid cooled guide bearings located inside the coil. The carriers slide on the bearings, and are pref. amde of austenitic steel coated with a layer of Ti carbide. The bearings pref. consist of an extruded profile made of austenitic material, whereas the cables are pref. made of austenitic steel. The metal blocks are e.g. blanks heated in the furnace prior to hot forging. The Ti carbide coating on the carriers improves their gliding properties and reduces wear, thus increasing their working life.

Title: Reaction type rotary IC engine - has jet outlets from combustion chambers producing rotation by reaction with separate pistons for compression
Inventor: GAIL JOSEF
IPC: F02B75/18
Filed: 1978-10-20
Abstract: The engine has a rotor (5) turning with a shaft (3) within a casing (1). At two diametrically opposite points the rotor has heads (7) containing combustion chambers (9). Each combustion chamber has a jet outlet (11) at an angle to the axis. The reaction of the gases issuing from this produces rotation.

These are driven from a crank (29) on the shaft and compress the fuel air mixture before it enters the combustion chambers through non return valves (51). The mixture enters through a pipe (41) coaxial with the shaft and passes through non return valves (45) in the pistons.

Title: Desulphurisation of gas esp. from heat engine generation station - using calcium carbonate suspension obtd. by decarbonation of water
Inventor: POLLER JUERGEN DIPL ING
IPC: C01F11/46
Filed: 1978-12-11
Abstract: Desulphurisation of gases, esp. combustion gases and/or smoke from a heat-engine generation station, by converting lime to gypsum is carried out with CaCO3 suspension obtd. by decarbonation of water. The amt. of material required from outside sources and the amt. of useless by-prods. formed are minimised, since the CaCO3 suspension is obtd. in the decarbonation of the cooling tower water with lime rather than acid.

Title: Expanded plastic shock absorbing package - with foam formed in mould around article in plastic bag
Inventor: HEUSER HANS
IPC: B65D81/113
Filed: 1978-12-14

Title: Variably curved or sloped gradient bridge superstructure - is made straight or constantly curved, and forwarded across piers built up to required levels
IPC: E01D21/06
Filed: 1979-09-20
Abstract: The constructional system is for a bridge. A gradient of varying slope or curvature is a feature of the completed bridge, which is made of reinforced or prestressed concrete, running continuously through a number of spans. The superstructure is made at one end of the bridge in a straight line or with constantly curved radius for its gradient. It is thrust lengthways along the bridge, across piers appropriate to the height of the desired gradient, right up to its ultimate position. It is pref. constructed and forwarded in a series of adjoining sections, in a staged process. This simplifies work of forwarding bent gradient or varyingly curved bridge superstructures.
