Patent DE-3900059-A1 (DE)
Inventor: JAKOBSON GERALD DIPL CHEM DR
IPC: C07C43/13
Filed: 1989-01-03
Abstract: The invention relates to a process for the preparation of polyglycerols (containing more than 50% by weight of diglycerol), which are low in cyclic components, by reaction of chlorohydrins. In this process,  alpha -monochlorohydrin and epichlorohydrin are reacted at temperatures of 20 to 120 DEG C, preferably of 50 DEG C to 100 DEG C, in a molar ratio of epichlorohydrin to  alpha -monochlorohydrin of 0.8:1 to 1:2.5 in the presence of acids or acid-reacting compounds and an alkaline-reacting medium, preferably an alkaline-reacting aqueous solution, is added to the unseparated reaction mixture obtained at a temperature of 50 DEG C to 120 DEG C, preferably of 80 DEG C to 95 DEG C, corresponding to the content in the reaction mixture of organically bound chlorine. The reaction mixture is desalted after addition of water by means of one or more cation exchangers and subsequently using anion exchangers, water is removed by distillation and the diglycerol/polyglycerol mixture (containing a proportion of glycerol) is separated into diglycerol, higher polyglycerols and optionally glycerol by fractional distillation.

Title: Arrangement for the releasable fastening of wall parts in intersecting bores of the pipes of a pipe structure
Inventor: FLACH EBERHARD DIPL ING
IPC: F16P1/02
Filed: 1989-02-13
Abstract: The novel arrangement is intended to permit the fastening of the covering of a pipe structure in one or even two planes by position-compensatable elastic plug-in elements, this allowing a rapid and variable mounting and demounting of machine claddings. For this purpose, the plug-in elements are designed as principal plug (1) and secondary plug (2). They are each seated in a bore (3.1) of the pipes (3) of a stable load-bearing structure and, by means of a peripheral groove (1.2; 2.2), receive the pipe wall in a clamping manner, this guaranteeing their axial fit, which is further secured by a principal pin (4) and a secondary pin (6) in that the latter are driven, as drivers, in a nail-like manner into a central bore (1.4; 2.4) of each plug (1; 2), this widening the bores (1.4; 2.4) and stabilising the connection. It can be released in a non-destructive manner. The fastening elements serve simultaneously as determining spacing. The arrangement is suitable for the variable assembly of standardised wall elements to form claddings which shield the working area of processing machines in a functionally appropriate manner. <IMAGE>

Patent DE-3906151-A1 (DE)
Title: Method of reducing the gas consumption during flame cutting
Inventor: HENRICI REINHARD DR
IPC: B23K7/10
Filed: 1989-02-28
Abstract: Flame-cutting machines are increasingly run in automatic operation with fewer operating personnel. Here, the flame-cutting operations are only started by the operating personnel and then proceed largely automatically, while the operating personnel perform other tasks. In the process, the flame-cutting area often cannot be observed directly. Due to organisational or technically induced interruptions in the production process which occur during the working period of the operator, the starting of the cutting programme can be delayed after the ignition of the flame. In order to reduce this consumption of gases which arises during the interruption in the production process, a method is proposed according to the invention in which a timing counter (26) is started as a function of the ignition of a flame (33) or a plasma arc. Upon reaching or exceeding a predetermined limit value, the timer (26) automatically switches off the gas supply or gas supplies (21) of the torch or torches (10) via a switching member (20). <IMAGE>

Title: Multiple treatment of liq. manure and thin sludge - by forming fine-dry material, useful as non-noxious fertilisers
Inventor: KRUESS HARTMUT DIPL ING
IPC: C02F11/13
Filed: 1989-11-07
Abstract: After preliminary drying, e.g. by filter press or in settlement tanks, liq. manure or thin sludge is divided into coarse and fine solids and a residue, mainly of water. Warm air reduces residual moisture content of the coarse fraction to 3% or less. Hot air drying of the filtrate aq. in a spray tower, produces fine solids, while clean residual water is condensed on a cold surface. A cyclical system with filter sections, spray tower, cyclone etc. forms both hot and cold material.  Heat from the circuit dries out raw material, while cold is used in condensing distillation. Waste power draws electrical generators. At any suitable stage to circulating material is sterilised, e.g. by microwaves. ADVANTAGE - Reduces external pollution of treated farming land, as compared with simple spreading. System is simple, with low energy demand, since balance between drying and condensation yields useful waste heat.
Patent DE-3937978-A1 (DE)
Inventor: VIOL GUSTAV DIPL ING
IPC: H05B39/02
Filed: 1989-11-15
Abstract: This switch-on current limiter limits the excess switch-on current occurring when switching on a load, for example a transformer (8) for supplying a low-voltage halogen lamp (9), it being possible for the switching on to take place universally via a switch (100), via a dimmer (7) without the mains phase connected, or via a dimmer (10) with the mains phase connected. To limit the current, a resistor stage (1) is connected in series with the load. After a delay time has elapsed, a switching stage (3) bridges the resistor stage (1). The switching stage (3) is driven with the aid of a mains power supply (2). A signal conditioning stage (4) receives the load voltage on the input side, forms a delay time and drives the mains power supply (2) via a switching amplifier. When the switch-on current limiter is in use on a switch (100) or a dimmer (10) with the mains phase connected, the delay time is generated by the mains power supply (2) itself. <IMAGE>
