Title: Process and apparatus for generating gas
Inventor: GRUMPELT HEINRICH
IPC: C10J3/26
Filed: 1985-12-09
Abstract: The essential problem in any fixed bed gasifier operating on the counter-current principle is condensate-rich gas formation resulting in cooling in the gasification material. However, fixed bed gasifiers operating on the co-current principle (and known as wood gas generators) do not guarantee condensate-free gases. The invention now provides, effectively in a three-chamber system 36, 40, 42, the preconditions for continuously heating the process gases taken off from the gasification chamber 11 of the reactor 1, and for converting these, by thermal cracking of the condensates, into non-condensable gases, and complete combustion of the latter to give odourless flue gases. This results in advantageous process linking of gas generation with the boiler 44 of a heating installation 2 for generating heating heat and/or process heat. <IMAGE>

Patent DE-3620090-A1 (DE)
Title: Internal combustion engine
Inventor: RUF MAX
IPC: F16B35/04
Filed: 1986-06-14
Abstract: In an internal combustion engine the cylinder head 1 is bolted to the cylinder crankcase 2 by differential bolts 8, which have two threaded sections 11 and 12, of which the first threaded section 11 has a larger outside diameter and a smaller pitch than the second threaded section 12. The threaded sections 11 and 12 interact with corresponding internal threads 13 and 10 in the cylinder head 1 and in the cylinder crankcase 2 respectively. Due to the differing pitches of the two threaded sections 11 and 12 the cylinder head 1 is clamped together with the cylinder crankcase 2 without the need for a bearing surface for a bolt head or for a nut. As a result the space required for the cylinder head bolting is extremely small so that the bolting can be provided at points, for example between adjacent valves, where no space would otherwise be available for a bearing surface for bolt heads or for nuts. Between the threaded sections 11, 12 the shank of the differential bolt 8 can be provided with a profiling, which increases the flow length of the bolt, as a result of which manufacturing tolerances for the position of the internal threads 13, 10 relative to one another can be compensated for. <IMAGE>

Abstract: Light transmitting glass which is a flat sheet has at least one surface area which is matted by surface pits. That surface area has a population of merging or contiguous surface pits, the pits being of such small area and profile that clearly legible typed characters of 10-pitch size are still clearly legible when viewed through such matted surface area when that surface is held at a distance of 10cm from the said characters. Light transmitting glass which is not a flat sheet and which has a surface area which is identically pitted is also disclosed. At least one matted surface area may be occupied by a population of surface pits which are of such small size that a disk having a diameter of 10 mu m cannot be placed thereon without overlapping at least two pits. In order to produce such glass the surface area is etched with a solution of a salt of hydrofluoric acid to leave a substantially contiguous population of fluorine-containing crystals, those crystals are removed to leave the surface area with a population of merging or contiguous surface pits, and the resulting pitted surface area is treated to remove a superficial stratum therefrom, in order to leave the surface area occupied by a population of merging or contiguous surface pits which are of such small size that a disk having a diameter of 10 mu m cannot be placed thereon without overlapping at least two pits. The preferred etching medium is aqueous potassium bifluoride, and the superficial stratum removal is preferably effected by chemical polishing e.g. using a solution containing hydrofluoric acid.

Title: Addition-subtraction circuit in 51111 code
Inventor: MERKLE PAUL
IPC: G06F7/491
Filed: 1987-09-05
Abstract: The addition-subtraction circuit according to the subject of the invention forms the subtraction result numbers additively, using a nine's complement circuit (8), which is combined with a straight-through circuit, and can thus be switched from passing straight through to nine's complementing and vice versa. For adding, the carry output (y) has high potential if the addition has a real carry. For subtracting, the carry output (y) has high potential if this circuit has only a circuit carry and thus no real carry. A subtraction therefore has a carry if the carry output (y) has low potential, and no carry if the carry output (y) has high potential. <IMAGE>
