摘要： An improved wall fastener for hollow walls, the fastener having two spreadable anchoring blades designed to spread behind the wall following insertion of a screw thereinbetween. The fastener is made of thin sheet metal which has been hardened through a heat treating process, such as quenching. Complementary engaging means on the blades are used to hold the blades together during the heat treatment and to prevent the separation thereof until the screw insertion.

摘要： A mass spectrometer suitable to measure both positive and negative particles, such as ions for example in a vacuum chamber. This spectrometer is provided with a turnable permanent magnet segment, which provides the gap of a yoke with adequate magnetic flux having the appropriate direction to separate the positive or the negative particles. Changing the polarity adjusts the flight path of the ions. Thus, negatively charged ions and positively charged ions will follow similar flight paths under opposite polarities, permitting the use of a single array of detectors. One or more coils may be used in place of or in addition to the turnable permanent magnet segment in order to provide the appropriate magnetic flux to the gap, and/or facilitate the turning process of the turnable magnet segment. The turnable magnet and/or the coils may be inside or outside the vacuum chamber. The detector may comprise at least one detector area, two charge mode amplifiers coupled to the detector area, a first CCD shift register coupled to a first one of the charge mode amplifiers and a second CCD shift register coupled to a second one of the charge mode amplifiers.

摘要： This invention pertains fasteners which are characterized by easy insertion and extraordinarily difficult separation of items that they attach together. This is achieved by a combination of snapping segments with multi-engagement configurations of engageable holes. The snapping segments may comprise anti-opening and/or anti-sliding portions, which immensely increase the strength with which the fasteners hold the objects together. Provision of an elastic body in the vicinity of the bottom section of the fasteners provides water and gas proof properties, and further eliminates squeaking noises. Vehicles comprising objects connected together by the fastening devices described and claimed herein are part of the instant invention.

摘要： A Spring fastener with critical configuration of the barbs, which allow the extraction of the fastener without destruction of the slot and/or the fastener. This critical configuration of the barbs allows spring fasteners to be used in slots of various widths and prevents rattling, which would take place in the case of spring fasteners of the present state of the art. The critical configuration is based on the special dimensions and special shape of the barbs with regard to the parts and the slots involved in assemblies of the spring fasteners and the parts. Assemblies of miscellaneous parts connected together by means of such spring fasteners, as well as vehicles comprising such assemblies may be made.

摘要： This invention relates to methods of controlling the oxidation of cyclohexane to adipic acid in the presence of a monobasic acid solvent, by extracting the catalyst from the reaction mixture, outside the reaction zone. Substantially all the unreacted cyclohexane, the majority of adipic acid, and preferably substantially all the monobasic acid solvent are removed from the reaction product. In the case that substantially all the monobasic acid solvent is removed, protic solvent, is added intermittently or continuously in the reaction mixture during the removal of the monobasic acid solvent, preferably by distillation, thus preventing solids precipitation. Dipolar aprotic solvent is then added in the presence of an adequate amount of the protic solvent (the total of dipolar aprotic solvent and the protic solvent constituting a novel combination solvent) to maintain a single liquid phase, followed by a step of extracting substantially all the catalyst in protic solvent. The catalyst extract is preferably recycled to the reaction zone, where the cyclohexane is oxidized to adipic acid. Thus, the novel combination solvent, which is preferably a combination of cyclohexanone with water, allows the dissolution of the reaction product, preferably after removal of the majority of the adipic acid, followed by a substantially complete extraction of the catalyst in water. No catalyst precipitation takes place, and all disadvantages and costs of solids handling are prevented.

摘要： This invention relates to a fastener, which expands by the insertion of an expanding member, preferably a screw. The fastener comprises a substantially flat head and two expandable legs. The head has an upper side and a lower side, preferably separated by a gap. The head also has a hole (round, oblong or otherwise shaped) in which the expanding body may engage or pass through for expanding the legs and securing one object to another object, such as a plastic panel to a metal sheet. The fastener also comprises a Y-shaped funnel configuration, which has been formed by a partial cut of the legs. Miscellaneous configurations of the Y shaped legs provide improved guidance to the expanding member, improved engagement to at least one of the objects, such as the metal sheet for example, and improved engagement to the expanding member, among other advantages. The fastener may also comprise portions under the upper side of the head, which portions are engageable to the expanding member. Further, the fastener of the present invention may comprise an elastic body at least under the head. This invention also relates to vehicles comprising parts connected by the fasteners of this invention.
