摘要:
A method for the automatic shifting of a multi-path toothed-wheel gear change box between two gears which are formed in a first gearbox subunit temporarily engages a middle gear formed in a second, parallel gearbox subunit. It is simultaneously ensured, by control of the working pressures for actuating the power-shift clutches connecting the gearbox subunits to the input shaft, that the speed characteristic of the input shaft shifting is essentially steady without remaining at the middle gear speed value.

An IFF system comprises an interrogation device having an antenna arrangement operating in the HF or microwave range with a relatively broad radiation characteristic for radiation of coded interrogation pulses and for receiving answer signals. The IFF system cooperates with a position finding device whose transmission pulses are radiated by way of a relatively narrow radiation lobe and wherein the answer signals are triggered in the answering device in response to the arrival of transmission pulses of the position finding device. A pulse laser operating in the optical range and having a very narrow radiation lobe at the transmission radiator is used as the position finding device and an answer signal is only triggered in the answering device with the aid of a control circuit when the transmission pulse of the laser transmitter arrives in a certain section during the interrogation pulse produced by the interrogation transmitter, the duration of the interrogation pulses being essentially greater than the duration of the transmission pulses.

A vehicle, especially a wheeled vehicle, for transporting and placing bridge parts of a portable bridge. The vehicle has a frame, on the forward end of which is mounted a cab. Behind the cab is mounted a support unit for use in placing the bridge parts. The support unit is pivotal about vertical axes and, during the placement process, is spaced from and in front of the cab and is located, in part, on the ground.

Described are methods and apparatus, referred to as “temperature-lock,” which can control and stabilize the sample temperature in an NMR spectrometer, in some instances with a precision and an accuracy of below about 0.1 K. In conventional setups, sample heating caused by experiments with high-power radio frequency pulses is not readily detected and is corrected by a cumbersome manual procedure. In contrast, the temperature-lock disclosed herein automatically maintains the sample at the same reference temperature over the course of different NMR experiments. The temperature-lock can work by continuous or non-continuous measurement of the resonance frequency of a suitable temperature-lock nucleus and simultaneous adaptation of a temperature control signal to stabilize the sample at a reference temperature value. Inter-scan periods with variable length can be used to maintain the sample at thermal equilibrium over the full length of an experiment.
摘要:
The present invention relates to the identification of molecular mechanisms associated with multidrug resistance (MDR) in fungal infections. More specifically, fungi harbor a nuclear receptor-like pathway controlling MDR, which represents a novel therapeutic target for the treatment of MDR in pathogenic fungi such as C. glabrata.

The present disclosure relates to reagents (antigenic and/or immunogenic reagents) and kits that are useful in a variety of in vitro, in vivo, and ex vivo methods including, e.g., methods for inducing an immune response, or for generating an antibody, in a subject. The reagents described herein can be used in the treatment or prevention of HIV-1 infections. In addition, the disclosure provides methods and compositions useful for designing (or identifying) an agent that binds to an membrane proximal external region (MPER) of an HIV-1 gp160 polypeptide or an agent that inhibits the fusion of an HIV-1 particle to a cell.
摘要:
A composition and method for inhibiting proliferation of a tumor cell compared to a non-tumor cell. Also described are methods of screening for a composition that inhibits cap-dependent translation compared to cap-independent translation of proteins.
摘要:
A sprocket chain with a plurality of links (1) pivotally bound together via pins (2). To enable the introduction of power, power input elements (5) are provided, the input elements (5) being separate from the pins (2), the end faces (6) of the input elements (5) possessing at least two contact surfaces (7) in the running direction of the sprocket chain.
摘要:
Described here is a process for controlling a passenger protection system by means of a CPU in conjunction with acceleration signals and the existence of at least one trigger inhibiting signal from a manually operated trigger inhibitor or a seat occupancy detection device. This process prevents errors in the CPU. For this purpose, monitoring of the trigger inhibitor and the seat occupancy detection devices is provided in an evaluation unit parallel to the CPU, in order to set an ignition inhibiting signal, as soon as at least one of these devices sets a trigger inhibiting signal. The ignition inhibiting signal influences the inhibiting device located between the CPU and the passenger protection device, disabling the trigger. This makes it impossible for an error in the CPU to trigger the passenger protection device inadvertently.
摘要:
The invention provides an arrangement for detecting the temperature of an automatic gearbox which has a temperature sensor and a starter-interlock contact switch in the gearbox component and, externally with respect thereto, a gearbox control device to which signal information from the temperature sensor and from the starter-interlock contact switch can be fed via separate signal lines. The temperature sensor and the starter-interlock contact switch are connected to a common signal line which leads to the gearbox control device, specifically in a series or parallel circuit arrangement.
