Patent DE-4129630-A1 (DE)
IPC: B64G1/28
Filed: 1991-09-06
Abstract: A three-axis stabilized, earth-oriented satellite has an attitude control system with regulators, actuators, an earth sensor that carries out measurements along two axes and a sun-sensor arrangement that also carries out measurements along two axes. The field of view of the sun-sensor arrangement covers the round angle on a plane of the satellite-fixed coordinate system. Only the sun-sensor arrangement and the earth sensor act as measurement transducers. A sun and earth acquisition process for such a satellite has the following steps: seeking the sun; setting the sun vector in a first direction of reference; setting the speed of rotation of the satellite around the sun vector at a constant value; setting the sun vector in a second direction of reference, so that by rotating the satellite around the latter the optical axis of the earth sensor sweeps over the earth; and picking up the earth. Special regulating rules are disclosed.

Title: Operating spinning plant section - with several spinning machines involves rough plan for mfg. lots based on contracts
Inventor: BIBER HEINZ
IPC: D01H13/32
Filed: 1992-06-23
Abstract: A process for operating a spinning plant section comprising several spinning machines, involves making a rough plan to determine which mfg. lot is produced at what time and with what quantity. The process uses a computer (122) and takes into account the basic prodn. data associated with the individual mfg. lots. The data has to be sufficient to work out the specific prodn. to be expected. The use of the machines and the prodn. that has taken place at an up-to-date period of time are also taken into account in carrying out a comparison with the target output set in the plan. A calculation is made as to when the target output will be reached. A comparison follows to establish whether the target times can be maintained. In the event of unacceptable delays of production shortfalls, the process involves investigating whether there is unutilised machine capacity in the spinning section in question. If the rough plane cannot be adhered to, this fact is registered. The process involves fine planning based on changing the mfg. lot on to another machine and the actual amt. produced is monitored continuously. ADVANTAGE - The operation of a spinning plant is made more economical and easy-to-follow.
Patent DE-4229258-A1 (DE)
IPC: A63H23/10
Filed: 1992-09-02
Abstract: The invention relates to a process for producing floatable hollow clay bodies, a gypsum mould, which is closed with the exception of a filling opening, being filled with a flowable clay composition, there remaining adhered to the interior surface of the gypsum mould a solid clay layer the thickness of which is dependent on the residence time and which, after the pouring out of the excess clay composition in the gypsum mould, forms a hollow body which, after initial drying, is removed from the gypsum mould, glazed and fired. Using the process, it should be possible to produce hollow bodies which, after they have been placed on a water surface, always assume a desired floating position and retain this. This is achieved in that, after the initial drying of the hollow body, it is preferably partly filled with a further clay composition while still in the gypsum mould and, after the initial drying of a suitable amount of the clay composition, the remainder of the clay composition is emptied out again, whilst, during the initial drying time, the hollow article is rotated and held in a position such that the aforementioned amount of clay composition dries in a layer which stabilises the desired floating position. <IMAGE>

Title: System for saving fuel during long descent of vehicle - uses automatic interruption of connection between engine and transmission
Inventor: MICHEL ADOLF
IPC: F16D48/06
Filed: 1992-09-08
Abstract: The connection between the engine and the transmission is automatically interrupted whenever the energy flow is from transmission to engine. The interruption is achieved by an automatic actuation of the clutch. With each decoupling the fuel flow is throttled back and the engine goes into an idling mode. USE/ADVANTAGE - Method for saving fuel whilst simultaneously protecting the engine. Avoids undue friction in the engine and allows the decoupling mechanism to be overridden if the engine is to be used as a brake.
Patent DE-4232516-A1 (DE)
Title: Uninterruptable power supply e.g. for use on island - has photovoltaic panels, wind generator, and storage battery connected in parallel to busbar, with emergency diesel generator
Inventor: BECK HANS PETER
IPC: H02J3/46
Filed: 1992-09-22
Abstract: The load busbars of an uninterruptable island power supply (UPS) are fed in parallel with photovoltaic panels connected to the load busbars through inverters, wind generating plant connected to the busbars through transformers, a storage battery with self-commutating inverters through a transformer, and a diesel-powered emergency generator. The photovoltaic panels and wind generators supply the load and the battery charging, and if there is insufficient solar or wind energy, the battery then provides a boost to the busbars. In extreme circumstances, the emergency generator will come on line to supply power, at the same time, charging the battery through line-commutating rectifiers. ADVANTAGE - Good power and reactive power control without need of continuously-running synchronous generator, using commercially-available equipment.

Title: Catalytic prepn. of methanol from synthesis gas contg. hydrogen@, carbon mon:oxide and carbon di:oxide - by sepg. methyl formate from prod. and feeding back to reactor to increase yield
Inventor: KOENIG PETER DR
IPC: C07C29/151
Filed: 1992-11-27
Abstract: In the catalytic prepn. of methanol from synthesis gas contg. hydrogen, carbon monoxide and carbon dioxide at 220-300 deg. C and at 20-120 bar pressure to give a methanol-contg. vapour. The vapour is drawn off and cooled to 20-60 deg. C giving a condensate contg. water, methanol and methyl formate and a gaseous mixture of hydrogen, carbon monoxide and carbon dioxide which is fed back to the reactor. A methyl formate-contg. fraction with 10-100 wt.% of methyl formate is sepd. from condensate and fed back to the reactor and mixed with synthesis gas. The methyl formate fraction is sprayed into the synthesis gas as a fluid. The methyl formate fraction is heated to 170-240 deg. C by the synthesis gas before being fed to the reactor. The fraction contains at least 30 wt.% of methyl formate, and is sepd. by distn. under pressure of 1-7 bar. The synthesis gas may have methyl formate from an extraneous source added before it enters the reactor. The methyl formate reacts with excess hydrogen to give further methanol. ADVANTAGE - Makes better use of the synthesis gas, giving increased yield of methanol. In an example, a synthesis gas contg. 3 vol.% CO2, 10 vol%CO, 70 vol% H2 and 17 vol% of CH4+N2 was reactred in a reactor (2) at 250 deg. C and 50 bar in the presence of a copper-zinc catalyst. A condensed product contg. 85.94 g of methanol and 0.65 g of methyl formate per hour was obtained and fed to a distillation column (17) working at 60 deg. C. The vapour produced was cooled to 20 deg. C giving a fluid product contg. 30 wt.% of methyl formate which was pumped (19) back to the synthesis gas line (1). Methanol prodn. rose to 86.65 g/h.
