摘要:
Mating closure part for a tailgate lock or door lock comprising a closure part with latch or the like and a mating closure part interacting therewith, having a closure member (2), in particular in the form of a closure block or closure bracket, which can be gripped by the latch and which, in order to generate a starting torque in closure direction (X), can be displaced from an open position (FIG. 3) into a closed position. The displacement of the closure member (2) is derived from the displacement of a threaded engagement part (spindle nut 3, 4) engaging in the thread of a rotationally driven spindle (5, 6).
摘要:
A separation module which contains at least one bundle of ceramic capillaries (9), in which, for controlling the material transport and the flow in the separation module, a certain distance is established between the capillaries (9) by joining. The separation module can be used in a variety of ways in the separation of substances by filtration, also in combination with further measures of chemical process engineering.
摘要:
Method and appliance for carrying out membrane electrophoresis using microfiltration or ultrafiltration membranes, wherein the electroosmotic flow which develops in the membrane pores is reduced or offset by pressure superposition. The appliance for the membrane electrophoresis comprises at least an at least quadrupartite separation chamber (7), having at least one diluate space (16) and one concentrate space (17) and also a cathode space (18) and an anode space (21) having electrodes as anode (19) and cathode (20), with the individual spaces (16, 17, 18, 21) being separated from each other by ultrafiltration or microfiltration membranes (14, 15); feed lines (22) and discharge lines (23) for the diluate, feed lines (24) and discharge lines (25) for the concentrate, optionally feed lines (26) and discharge lines (27) for the electrode rinsing solution, and also a device (8; 10) or (9; 11) for pressure regulation by means of which a pressure difference, in particular of at least 3 kPa, can be generated between the diluate space (16) and the concentrate space (17).
摘要:
Packing consisting of a plurality of twisted strips stacked parallel to each other in an axially symmetrical arrangement. Twisting produces spirals rotating in the same sense. In addition, the strips are pleated to produce waves perpendicular to the axis of the spiral. When the packing is assembled from the spirals, the individual spirals are staggered in relation to each other to form continuous channels extending in straight lines in four axially symmetric directions. The axially symmetric directions are defined in that their projections in the horizontal plane form an angle of 90.degree. with each other and an angle .alpha. formed between the said axially symmetric directions and the axis of symmetry of the packing depends solely on the ratio of the widths of the spirals to their pitch.
摘要:
A device and a process are described for membrane electrophoresis or electrofiltration. The device contains at least one input chamber, one output chamber, and one cathode chamber and anode chamber each, whereby the individual chambers are separated from one another by membranes, and are integrated into a permanently attached module with membranes, and whereby the electrodes are integrated into the module, and the module is connected to constructions enabling continuous flow through the input and output chambers, as well as through the electrode chambers. It is emphasized that this abstract is provided to comply with the rules requiring an abstract which will allow a searcher or other reader quickly to ascertain the subject matter of the technical disclosure. It is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the appended issued claims. 37 CFR §1.72(b).
摘要:
A first alkanol having 1 to 3 C atoms or a mixture of this first alkanol with water or water itself can be separated off from oxygen-containing organic compounds having 3 to 7 C atoms from the group comprising second alkanols and dialkyl carbonates, which always have at least 2 C atoms more than the first alkanol, by permeation on membranes if a membrane obtained by plasma polymerization is employed.
摘要:
Diastereomers can be separated with good industrial success with the aid of extractive distillation. The separation process is characterized in that an auxiliary which changes the partial pressure of the various diastereomers to be separated to a different degree and thus allows easier separation of the diastereomers by distillation is added during the distillation. Using the present process diastereomic cis/trans-permetric acid methyl esters and mixtures of menthol and isomenthol can be separated with isolation of 99% pure product.
摘要:
The invention relates to a casing for a key with sensors that are positioned inside the casing and that are actuated by means of push buttons, so that the push buttons are situated in openings of a casing cover and can be displaced against a rebound force perpendicularly to the surface of the casing cover in the direction toward the sensors. In order to improve a generic casing both in terms of production technology as well as in advantageous uses, it is proposed that the push buttons made of a hard plastic are inserted with lateral distance in the openings and are held in place by a soft plastic inset inserted into a recess in the casing cover.
