摘要:
An electrical connector element having at least one contact receiving member for an electrical contact element which can be inserted in an insertion direction (E) as far as its end position (F) into the at least one contact receiving member, having a locking member by means of which the contact element in its locking position (L) can be secured in the end position (F) against being removed from the at least one contact receiving member counter to the insertion direction (E), and having a securing member which retains the locking member in the locking position (L) in its securing position (B). In order to better secure the contact elements against being removed from the contact receiving members, there is provision according to the invention for the securing member in the securing position (B) to at least partially protrude into the at least one contact receiving member and consequently for the contact element to be able to be additionally secured against being removed from the at least one contact receiving member counter to the insertion direction (E).

Titanium-aluminium mixed oxide powder with a proportion of aluminium oxide of less than 1 wt. % or a proportion of titanium dioxide of less than 5 wt. %, wherein the sum of the proportions of titanium dioxide and aluminium oxide is at least 99.7 wt. %. It is produced by transferring a vaporous starting compound of the quantitatively greater component of the mixed oxide into a mixing chamber by means of primary air and a vaporous starting compound of the quantitatively smaller component of the mixed oxide by means of an inert gas, and burning the mixture mixed with hydrogen in a mixing chamber into a reaction chamber. It can be used as a catalyst support.

In an emulator processor cluster, the read ports of a shared input and data memory stack are time multiplexed to serve more than one processor. In an exemplary embodiment of the invention, a 256×8 memory array serves as the shared memory for four processors in a cluster. Two read ports are time multiplexed among the four processors in the cluster. On one read cycle, data from the two read ports is coupled to two processors. The next read cycle reads data from the same two ports to the remaining two processors. In the preferred embodiment, the memory operates at twice the system clock speed so that overall emulation process execution time is not effected.

A safety device is included in a circuit comprising a power source and a user device. The power source has one terminal connected to ground, as does the user device, with the safety device connected in a conducting path leading to the ground in the user device. In the event of an incorrect polarity connection between the power source and user device, a current path through the safety device and to ground is established.

摘要:
Process for the production of doped metal oxide particles, wherein the doping component is present on the surface in the form of domains, wherein in a first reaction zone, an oxidizable and/or —hydrolysable metal compound as dopant together with an atomization gas is atomized into a flow of metal oxide particles in a carrier gas, wherein the mass flow of the metal oxide particles und —the mass flow of the dopant are selected such that the doped metal oxide particles contain 10 ppm to 10 wt. % of the doping component, where the quantity of dopant to be introduced is calculated as the corresponding oxide, and wherein the temperature in the first reaction zone is —selected such that it is below the boiling temperature of the dopant under the prevailing reaction conditions, and then, in a second reaction zone, the flow from the first —reaction zone and optionally at least as much oxygen and/or steam are —introduced that the quantity of oxygen and/or steam at least suffices completely to convert the dopant, wherein the temperature is from 300 to 2000° C., —preferably 500 to 1000° C., and the reaction mixture is then cooled or allowed to cool and the doped metal oxide particles are separated from the gaseous substances.
摘要:
An electrical plug connector includes a first housing and a second housing. The first housing includes first electrical contacts arranged in first and second contact zones. The second housing includes second electrical contacts arranged in first and second contact holders. The second contact holder is displaceable with respect to the second housing in a direction of mating when the first and second housings are mated. The second contact holder is displaceable between a first position where the second electrical contacts of the second contact holder mechanically engage the first electrical contacts and a subsequent second position where the second electrical contacts of the first contact holder mechanically engage the first electrical contacts.
摘要:
A connector housing and a process for making same, in which the connector housing comprises a base part and a pivoting part, attached to the base part and made in one piece with the base part. The pivoting part has at least one surface delimiting an insertion opening in the connector housing through which a pin contact may be inserted into a socket contact in the connector housing. The connector housing being injection molded, with the pivoting part located in an open position, providing sufficient space for the molds for shaping a latching hook. After the mold has been removed, the pivoting part is moved into a closed position in which the delimiting surface of the pivoting part is moved towards the insertion opening. The connector housing cures with the pivoting part in the closed position. The socket contact is held in a contact chamber by a latching hook.
摘要:
A cooling device for liquid-cooled internal combustion engines, which device includes an annular radiator core or block which is traversed by the cooling air from the inside thereof toward the outside thereof, with a radial-flow fan or blower equipped with a rotor being arranged on the inside of the annular radiator core or block for axially sucking in the cooling air through an opening provided in a vehicle housing. A second annular radiator core or block for cooling the fuel for the internal combustion engine is disposed concentrically within the first-mentioned annular radiator core or block at a position downstream of the rotor, as viewed in the intake direction of the cooling air. The rotor of the radial-flow fan or blower is constructed such that a communication is provided between each vaned duct of the rotor and an annular rotor side chamber disposed within the second annular radiator core or block to effect a stream of cooling air through the second annular radiator core or block.
