IPC: C30B15/00
Filed: 1987-01-22
Abstract: In growing single crystals of semiconductor silicon by the Czochralski method from a melt, a travelling magnetic field is applied to the melt. The effect of applying the travelling magnetic field is to suppress the thermal convection flux in the melt and consequently to reduce the oxygen concentration in the silicon single crystal pulled in this way, without increasing the variation in the resistivity in the plane of the silicon wafer produced by cutting up the single crystal.
Patent DE-3705045-A1 (DE)
Title: Split motor
Inventor: KANIUT HERBERT DIPL ING
IPC: F02B1/04
Filed: 1987-02-18
Abstract: Split motors comprising two or three component internal combustion engines are suitable for reducing the quantities of engine exhaust gas, alleviating smog conditions and reducing environmental pollution in traffic jams and traffic-calmed zones. The component internal combustion engines have their own component crankshafts, are accommodated in series in a common engine block and function automatically as start/stop modules. Self-synchronising clutches of viscohydraulic-mechanical type are installed between the component crankshafts, which clutches work according to the "two-directional principle", which start the component internal combustion engines one after another and automatically bring their component crankshafts into fixed-phase synchronous operation after TWO full relative revolutions respectively, by means of special control mechanisms. For overall control of the split motor, a microprocessor control (Fig. 8) is provided as an alternative to mechanical-electrical control. The different compression ratios, numbers of inlet/exhaust valves and degrees of turbulence of the combustion in the component internal combustion engines are combined with one another according to the principle shown (in Fig. 9). <IMAGE>

Patent DE-3709778-A1 (DE)
Title: Method of sealing soil
IPC: C09K17/12
Filed: 1987-03-25
Abstract: The invention relates to a method of sealing soil. While a known method for this purpose requires a mixture of sodium hexafluorosilicate and sodium silicate in an amount of approximately 80% of the soil and compaction using low-pressure steam being necessary, an improvement is achieved according to the invention in that the sealing process is carried out merely by loess loam which has been delimed substantially by precipitation water and which has a suitable content of cations of a higher valency. The mixture is prepared in the dry state and has outstanding storage properties. Only small amounts of water are required to liquefy prior to application to the soil. The sealing is caused by gelling, which takes place after application to the soil. The actual mixture contains the delimed loess loam, which has a brown colour mainly caused by Fe2O3, in a largely known composition, so that only a few parts per thousand of added sodium silicate are required.
Patent DE-3716292-A1 (DE)
Title: Method and arrangement for constructing a diaphragm wall
Inventor: SCHEBEN WERNER
IPC: E02D19/18
Filed: 1987-05-15
Abstract: In order to make excavations impermeable to water, it is known to construct trench walls around the excavation in the earth. The trench walls remain in the earth after completion of the construction work. This leads to the disadvantage that groundwater flows are deflected and bring about a change in the earth. The groundwater also builds up in front of the trench walls, whereas it sinks behind it. In order to avoid this, a bag (10) impermeable to water is placed in the earth trench which is filled with the diaphragm-wall mass for forming the trench wall (7). The bag (10) is filled with a heavy liquid so that part of the trench is filled by the bag (10). After completion of the protection against water, the bag (10) is emptied and removed from the trench, whereby an opening results in the trench wall (7) which is filled with a material permeable to water. <IMAGE>

Title: Connecting device for tombstones and structures of a similar configuration
Inventor: KETTLER PAUL ERICH
IPC: E04H13/00
Filed: 1987-05-28
Abstract: Connecting device for tombstones and structures of a similar configuration having a fixed and also a releasable connection between the lower part, comprising a base and/or foundation, and an upper part (e.g. tombstone). In the case of the known releasable and non-releasable connections of the tomb parts, dowels have had to be used. In this arrangement, use was made of mortar or an adhesive. Since dowel material and stone material expand differently at different temperatures, the stability of the dowel in the stone material was not ensured. The invention proposes a better solution for this, which is characterised in that the upper part (1a) is connected to the lower part (2, 3) via a turnbuckle, and there is provided, between the upper part (1) and lower part (2, 3), a gap (4) which is fixed by spacing means and through which an actuating means (wrench) for the turnbuckle can be guided. <IMAGE>

Title: Hydraulic brake booster for vehicle - has adjuster piston sliding on master cylinder piston push rod in connection with control slide
Inventor: LEINEWEBER GUENTER
IPC: B60T8/40
Filed: 1987-08-04
Abstract: The hydraulic power booster for vehicle hydraulic braking systems has a booster piston sliding axially in the bore of a valve housing. Its boost power is transferred to a following master cylinder by a push rod. Sliding axially on the push rod is an adjuster piston forming a power producing member connected to the control slide so that activation of the adjuster piston causes the control slide to move against the brake operating force. Thus the brake booster remains active even during the brake modulation phase so that there is no noticeable free movement of the control slide otherwise causing reaction on the pedal. ADVANTAGE - Keeps the pedal reaction during the modulation phase of an antilock cycle low.

Title: Process for disposing of waste by incineration with oxygen
Inventor: MENGES GEORG PROF DR ING
IPC: F23G5/00
Filed: 1987-10-16
Abstract: The process consists of a plurality of steps, in which wastes, especially plastic wastes, in order to reduce the amount of exhaust gas - equivalent to smaller exhaust gas purification plants, reduced power requirements and reduced pollutant emission - and to increase the flame temperature are incinerated with combustion gases containing more than 50 % oxygen. The exhaust gases are cooled in a lost-heat boiler and purified in a gas purification plant. The steam produced is used for operational purposes. So as to bind any harmful compounds formed during incineration, metal-containing substances are incinerated at the same time, or these or alternatively alkali metal or alkaline earth metal compounds are admixed to the exhaust gas stream to bind the pollutants. This process is particularly suitable for recycling old cars. This involves incinerating, with oxygen, the waste produced in shredding, which consists of rubber, plastics and others, together with non-ferrous metals from the process, and the steam produced is used to drive the shredder. The metal-containing dusts produced in a filter separator are used in a metal recovery process.

Title: Pressure pick-up for detecting an air-conditioning flow including a ventilating conduit and a measuring method
Inventor: KORFMANN WERNER DIPL ING
IPC: E21F1/04
Filed: 1988-01-11
Abstract: The invention relates to a pressure pick-up for detecting an air-conditioning flow in or at the end of a ventilating conduit. The pressure pick-up is designed in a rod shape and measures the pressure difference between the air-conditioning flow flowing in and that flowing out and, from this difference measurement, the volume flow or the exhaust quantity is determined with the aid of preferably stored calibration curves. The ventilating conduit to be surveyed is preferably provided with pairs of holes at regular spacings, which are closed with the aid of stoppers when not used. The special feature of the method likewise covered by this invention is the detection of almost the complete cross-section of the ventilating conduit with the aid of a pressure mean value which enables measured values with an accuracy not previously possible to be expected.
