Patent DE-3835381-A1 (DE)
Title: Burner
Inventor: ALTEMARK DETLEF DR ING
IPC: F23D14/74
Filed: 1988-10-18
Abstract: The burner has a combustion chamber having a nozzle at the end (2) situated downstream, and a casing (3) which surrounds the combustion chamber and serves to feed oxygen-carrier gas to the flame emerging from the nozzle. Formed between the combustion chamber (1) and the casing (3), which are constructed as separate components which can be twisted and displaced with respect to each other, at the end situated downstream, are jet openings (4, 4') for the oxygen-carrier gas. The oxygen-carrier gas jets emerge from the jet openings in a converging manner and locate themselves partially in recesses in the flame and partially on the periphery of the flame. The mixing of the oxygen-carrier gas with the flame with inclusion of exhaust-gas recirculation (layer arrangement flame/exhaust gas/secondary air/exhaust gas) can be adapted very well to optimisation of NOx emission/flame length. <IMAGE>
Patent DE-3838317-A1 (DE)
Inventor: HILBING ANTON
IPC: A44C17/04
Filed: 1988-11-11
Abstract: With a process for setting precious stones, especially brilliants, in precious metals or their alloys, the precious stone being surrounded at least in regions by the metal forming the setting, a solution is to be produced, with which precious stones, especially brilliants, can be set mechanically, the mechanical preparations being reducible to a minimum, as a result of which the setting process can be speeded up. This is achieved in that the precious stone is pressed under pressure into a borehole, the diameter of which is slightly smaller than the external diameter of the precious stone to be set, and in that, after the outer edge regions of the precious stone have been driven into the borehole below the level of the surface of the setting metal, metal material is rubbed from above over the outer edge regions of the stone to be set. <IMAGE>

Title: Two stroke IC engine - has means to change timing of opening and closing of inlet valve
Inventor: KRUEGER HERMANN DR
IPC: F02B1/04
Filed: 1990-04-19
Abstract: The two-stroke internal combustion engine has at least one inlet and one exhaust valve per cylinder. It has the valve timing arranged to provide an overlap in the operation of the two valves in order to scavenge the combustion chamber with fresh incoming air.

Controls are provided to change the timing of the opening and closing of the inlet valve when operating under part load. The effective stroke of the piston is then increased from (Vv) to (Vt) but the angle (alpha) of rotation of the crankshaft between opening and closing remains the same. USE - Two stroke IC-engines.
Patent DE-4016127-A1 (DE)
Title: Setting ignition timing of IC engine - using predetermined reference data, engine condition and ambient sensors to optimise ignition timing for max. smooth torque
Inventor: OHKUMO HIROYA
IPC: F02D45/00
Filed: 1990-05-18
Abstract: Data are used for a setting value which is subsequent modified by signals from sensors monitoring crank angle (20) air intake (21) coolant temp. (22) and pre-ignition knock (26). The outlet of pre-ignition is used as a benchmark signal to retard the ignition point by a relatively large amount as a first approximation. Comparison is made with a reference level and the resulting difference initiates coarse and fine correction signals leading to rapid adjustment of engine timing to compensate for all engine and fuel aminities.

Patent DE-4028370-A1 (DE)
Inventor: MUELLER FRED-EGON DR ING
IPC: H03D9/06
Filed: 1990-09-07
Abstract: A modulator suitable for 16 quadrature amplitude modulation (QAM) is designed as a double modulator (1), wherein a 16 QAM modulator (39) consists of two double modulators (1). One double modulator (1) has two partial modulators (1',1'') forming a bridge. Each partial modulator (1',1'') has two possible transmission paths: (6',6'') with a phase delay line (39',39'') which causes a 180 DEG  phase shift. On each of the two paths (6',6'', 7',7''), a semiconductor diode (D1',D1'',D2',D2'') is disposed in such a way that they provide the carrier (Uc) with a 180 DEG  phase inversion and are accordingly rendered conductive in unison, if no modulation voltage (Um) is applied, whereby the carrier is suppressed at the signal output (3'). When a modulation signal (Um) is applied, the balance is changed to push-pull, and one of the two paths (6',6'') assumes less impedance compared to the other path (7',7''), which leads to the generation of the modulated carrier voltage (Umc). Through its design as a double modulator (1) such that the transmission path is realized respectively via an electrically short path (7',7'') of one partial modulator (1',1'') and via a phase delay path (6'',6') of the other partial modulator (1',1'') or conversely, differences in the two paths are averaged. The double push-pull modulator (1) is used in radio link systems. The modulator (1) can also be used as a mixer.
