Patent DE-3606173-A1 (DE)
Title: Process for the preparation of educt-free diethylene glycol dimethyl ether by methylation of diethylene glycol monomethyl ether
Inventor: SCHWENK ULRICH DR
IPC: C07C41/16
Filed: 1986-02-26
Abstract: In the novel process, diethylene glycol monomethyl ether is methylated with methyl chloride in the presence of alkali metal hydroxide. The methylation is carried out at a temperature of 40 to 80 DEG C without solvent, the methyl chloride and the alkali metal hydroxide being employed in each case in an at least stoichiometric amount. To obtain the desired diethylene glycol dimethyl ether, the entire reaction product is subjected to incipient distillation, and as soon as the distillation is about to stop due to poor heat transfer, the remaining amounts of dimethyl diglycol are distilled off together with the water present in the sodium hydroxide solution using the heat present in the salt which has been produced, whereupon this crude distillate is subjected to purification by fractionation in a second distillation step. The second distillation step can be carried out with an even better result in the presence of boric acid.
Patent DE-3610742-A1 (DE)
Title: Supporting insulator
Inventor: SCHMIDT ROLAND
IPC: G01R19/155
Filed: 1986-03-29
Abstract: A supporting insulator which can be allocated to an electrical high-voltage installation, consisting of insulating material and has two mounting fittings, which are inserted therein and face one another in the longitudinal axial direction, for the connection of the supporting insulator on the high-voltage side and on the earth-potential side, and has at least one metallic, capacitive divider element which is formed into the insulating material, is distinguished by the fact that the capacitive divider element (17) is located at predetermined intervals between the mutually facing ends of the mounting fittings (11; 16) and is conductively connected to a connecting element (19), which is preferably passed out at that longitudinal end of the supporting insulator (10; 21) on the earth-potential side but is insulated with respect to the earth potential, for the connection of a voltage display unit (29). In consequence, the possibilities for the connection of a display element for displaying the voltage status of elements which can be loaded with potential can be improved without having to affect adversely the reliability of the earthing or even the breakdown strength of the supporting insulator. <IMAGE>

Title: Telescopic drilling implement
Inventor: ECKER ROBERT DIPL ING
IPC: E21B17/07
Filed: 1986-04-16
Abstract: The making of roof-bolt holes in rise headings or even in other areas in underground mining is substantially facilitated and made possible in one operation by the drill-pipe string being formed in several pieces and from telescopic rods which are to be coupled one after the other with the advance and are locked to one another in the extended position. A drill-hole length is thereby obtained which far exceeds the overall length of the drilling implement so that sufficiently deep or long roof-bolt holes can be made in the rock even at seam thicknesses of about 1 m. <IMAGE>

Patent DE-3636008-A1 (DE)
Title: Electrical machine having a stator winding which is produced using the total impregnation technique
Inventor: HERZOG KURT
IPC: H02K3/40
Filed: 1986-10-23
Abstract: In the case of the use of the total impregnation technique on machines having a relatively high power and/or rated voltage and thus relatively great machine iron lengths, in the event of temperature changes in the machine, the expansion differences may be so great that they can no longer reliably be absorbed by the bonding points of the stator laminated core/insulation and insulation/copper conductors. The consequences are local cracks and slackening. At the same time that the machine powers are becoming greater, the exciting current forces, which act mainly in the radial direction, in the conductors are increasing, so that said conductors can rotate at twice the mains frequency once they initially become loose. This results in mechanical destruction of the main insulation, which can finally lead to failure of the machine. The suitable construction of the slot filling thus has major importance in the case of increasing machine power. This problem is solved according to the invention in that the insulating winding bars (2, 3) are provided with a low-friction coating (9) on all sides, while the slot closure wedges and the bar intermediate layer (4) are bonded firmly to the laminated body (1). In consequence, the bars (2, 3) can be held securely in the radial direction in the slot. On the other hand, the bars (2, 3) can expand in the axial direction in the slot, without any delamination occurring within the insulation (8) or between the insulation and conductor harness. <IMAGE>

Title: Grip for tennis rackets with integrated hydraulic shock absorber
Inventor: PFEIFER ANTON ING GRAD
IPC: A63B60/54
Filed: 1987-02-28
Abstract: A hydraulic shock absorber is used for grip damping, primarily on tennis rackets and, in the extended sense, on motorcycles and machines. Damping on tennis rackets has hitherto been achieved by an appropriate design of the frame, but to a very limited extent. By the installation of a hydraulic shock absorber in the grip, a substantial increase in the damping effect can be achieved, and this effect can be adapted to requirements by simple adjustment. Furthermore, this form of damping can also be used on motorcycle handlebars or on hand-grips for machines. The hydraulic grip damping is primarily used in tennis rackets, in order as far as possible to prevent damage to health such as bruising of the muscles or wrist. Furthermore, the same effect can also be applied to motorcycle handlebars or to hand-grips on machines which are subject to impact or vibration loads.
