  • Patent number: 5869434
    Abstract: The invention relates to the use of at least predominantly linear hydrocarbon compounds olefinically unsaturated in the alpha-position with flashpoints of at least about 80.degree. as the oil phase or as part of the oil phase of oil- or water-based free-flowing borehole servicing preparations. Particular significance is attributed to corresponding drilling fluids which, together with the alpha-olefins, contain other oil phases from the field of borehole servicing preparations and are distinguished by ecological compatibility, being degradable under both aerobic and anaerobic conditions. Suitable mixture components for the oil phase are, in particular, oleophilic alcohols, ethers and corresponding esters selected from carboxylic acid esters and/or carbonic acid esters.

  • Patent number: 5561409
    Abstract: A holder is provided for a cylindrical electrical safety fuse having conductive end caps. A hollow housing receives the fuse therein through a front side which is closeable with a closure cap. A compression spring at a back end of the housing biases the fuse against a conductive metal inner cap disposed interiorly of the end cap. The inner cap has a radially extending contact tab. A terminal pin is provided to conductively engage the contact tab. The terminal pin has a contact portion with a perpendicularly-extending base, a cantilevered front leg extending from and overlying the base, and a cantilevered spring leg extending from a second end of the base so that the spring leg is disposed intermediately between the front leg and the base and also overlies the base. A clamp slot is defined between the front leg and the spring leg to form an electrical contact with the contact tab.

  • Patent number: 5513187
    Abstract: For real-time testing, two test combinations TK1 and TK2 are written to the input trigger circuits (EK1 to EK2) of the logic circuit (LS1) to be tested and to the output trigger circuits (AP1 to AP2) of the upstream test device (TE) or of an upstream logic circuit (LSO). The second test combination TK2 is transferred with the first system test pulse to the input trigger circuits (EK1 to EK3), and with the second test pulse the associated output combination (AT2) is transferred into the output trigger circuits (AK1 to AK2). This output combination is subsequently transferred into the test device (E) and checked. An integrated circuit suitable for carrying out the process has trigger circuits with two clock inputs.
