摘要:
Pin and box elements for the separable connection of the ends of the respective halves of a slide fastener are applied by deflecting the coupled stringer previously provided with the slider, at an angle to enable the elements to be threaded through the window onto respective edges in the shadow of the deflected stretch of the band.

Strongly exothermic, catalytically induced or promoted chemical reactions, e.g. the production of methane by the reaction of hydrogen with carbon oxides, are carried out by passing the reactants through an isothermically operated reactor in addition to an adiabatic reactor.

A liquid-pickup apparatus for carpetry, e.g. for the removal of liquid from the shampooing of a carpet, comprises a slot-shaped compressed air outlet adjacent a discharge duct with an entry slot. The flattened cross-section duct rises at an angle to the horizontal and is subdivided internally into a plurality of channels of substantially the same cross section as the slot and having rounded bases.
摘要:
A method for manufacturing a hydraulic device is described, in which at least one hydraulic channel and at least one connection are manufactured and/or hydraulically connected to one another, the hydraulic device being manufactured from at least two plates, and the plates being formed and connected to one another with the aid of the processes of cold forming, deep drawing, punching, punch riveting, and/or clinching.

A fuel distributor, which is used in particular for fuel injection systems of mixture-compressing spark ignition internal combustion engines, includes a tubular base body, a first holder and a second holder. The first holder is connected here to the tubular base body at a first fastening point of the tubular base body. The second holder is also connected to the tubular base body at a second fastening point of the tubular base body. The tubular base body has at least one bend at least between the first fastening point and the second fastening point. A base body having a meandering pattern may be implemented in this way, enabling adjustment of thermal changes in the length of a cylinder head on which the fuel distributor is mounted.

An electropneumatic actuator system for operating assemblies of an internal combustion engine includes a housing, in which an actuator is movably accommodated, which in turn is configured to be hollow and includes an aeration channel and a deaeration channel. A control slide valve is assigned to the actuator which is operated by a magnetic coil and which aerates, deaerates or closes a pressure chamber of the housing as a function of the relative position of the actuator.

An integrated circuit includes an input terminal for applying an input signal, a further input terminal for applying a further input signal having a level differing from the level of the initial input signal, an output terminal for providing an output signal, a switching unit having a controllable switch, which is arranged between the input terminal and the output terminal, and a further switching unit, which is arranged between the further input terminal and the output terminal. The integrated circuit is operated in a first and subsequent second operating state. The controllable switch of the switching unit is controlled to be conductive in the first and second operating state. In the first operating state, the output signal is provided in dependence on the level of the input signal, and in the second operating state in dependence on the level of the second input signal.

A stretch-blow molding machine having at least one blow molding station, in which a split blow mold, an adjustable blow nozzle with a valve section, a stretching rod with a stretching rod drive system, and an electronic control unit are provided, the electronic control unit arranged in the blow molding station is equipped with hardware and software for selectively operating the blow molding station with a combination of a cam drive and a pneumatic drive, or a combination of an electric servo drive and a pneumatic drive, or only an electric servo drive in the stretching rod drive system. The movement of the stretching rod is initiated in the stretch-blow molding machine in the production process of a container by means of an electric servomotor with the beginning of or during the locking phase of the blow mold and before the blow nozzle is placed, and the stretching rod is already displaced to a position in which the stretching rod is either very closely approached to the preform bottom or contacts the preform bottom, or has even already pre-stretched the preform, until the blow nozzle is placed.
摘要:
A semiconductor memory having read amplifier strips having a plurality of read amplifiers and having memory cell fields which have a plurality of memory cells connected to bit lines is disclosed. The read amplifier strips include at least two outer read amplifier strips between which the remaining read amplifier strips and the memory cell fields are arranged, wherein adjacent to at least one of the outer read amplifier strips, a reference circuit field is arranged, which has reference lines and reference circuit elements connected thereto, and wherein the reference lines are shorter than the bit lines of the memory cell fields.
摘要:
PTH compounds having PTH-like activity and comprising at least one modification, said modification being either 1. at least one radical selected from a L- or D-α-amino acid, C2-6alcoxycarbonyl and optionally substituted C1-8alkyl, C2-8alkenyl, C2-8alkynyl, aralkyl, aralkenyl or C3-6cycloalkyl-C1-4alkyl and attached to the terminal amino group of the PTH compound, and/or at least one radical selected from C2-6alcoxycarbonyl and optionally substituted C1-8alkyl, C2-8alkenyl, C2-8alkynyl, aralkyl, aralkenyl or C3-6cycloalkyl-C1-4alkyl and attached to one or more side chain amino groups of the PTH compound, or 2. at least one α-amino acid unit in the positions 1 to 38 of a naturally occurring PTH sequence being replaced by a natural or unnatural amino acid unit optionally in protected form, whereby the α-amino acid units present in positions 1 and 2 at the amino terminus of the PTH sequence may be replaced by a pseudo-peptide, or a combination of such modifications, in free form or in salt form, have pharmacological activity, e.g. for preventing or treating all bone conditions which are associated with increased calcium depletion or resorption or in which calcium fixation in the bone is desirable.
