Patent EP-0304620-A2 (EP)
Inventor: SCHMITZ HERBERT
IPC: H02B1/04
Filed: 1988-07-20
Abstract: A multipin contact insert with a fitted housing for switch cabinets or the like is designed such that the fitted housing can be inserted in a recess in a wall of a switch cabinet or the like and can be mounted using screws with the aid of flanges which are located on the outside of the switch cabinet wall. In contrast, the contact insert is inserted from the inside of the wall and is mounted on the fitted housing by means of screws. In this case, four assembly columns, provided with internal threads, project inwards from the inwards facing side of the fitted housing, into the edge recess. When the contact insert is inserted, retaining straps projecting from the contact insert rest on these assembly columns. This design of the fitted housing can be used with or without terminal adaptors. In both cases, the connecting lines are fitted in advance and the contact insert is then inserted from the inside, with or without terminal adaptors, and is screwed to the fitted housing.

Abstract: The adhesive is used to bond natural or synthetic elastomers to metallic or nonmetallic substrates under vulcanisation conditions and is based on aqueous dispersions. Such dispersions contain an organic, polymeric film former, an aromatic polynitroso compound, a coactivator and optionally conventional adhesion-improving additives, fillers and processing assistants. In order to broaden the range of applications and to ensure high resistance of the adhesive bond to corrosive effects, the coactivator employed is, in particular, phenylenebismaleimide.

Abstract: The base plate (3) of a hollow floor (2) is laid on the uneven and inclined surface (11) of a building component (1). A top plate (6), on which optionally also a footstep sound insulation (7) is laid, is laid on the spacers (4) connected to the base plate (3). The said footstep sound insulation can be covered by a sealing foil (8), so that the cast floor (9) placed above is unable to flow through. The top surface (91) of the cast floor (9) is horizontal and even. A hollow floor (2), the cavity (10) of which is well defined on all sides and therefore very suitable for inserting conduits, is thus obtained. The combination of the dry construction method with the cast floor affords the advantage that the latter can be constructed and put to use rapidly (short drying time of the thin cast floor) and is at the same time absolutely even, without the complicated levelling work of other floors being necessary. <IMAGE>

Abstract: An auxiliary steering control apparatus for use with a motor vehicle having a vehicle speed sensor sensitive to a vehicle speed. A control unit is coupled to the vehicle speed sensor for sampling the sensed vehicle speed at time intervals and calculating a vehicle speed change between a new value of the sensed vehicle speed and the last value of the sensed vehicle speed is calculated. The control unit calculates a control vehicle speed value which is equal to the new vehicle speed value when the calculated vehicle speed change is less than a limit value and is equal to the last vehicle speed value plus the limit value when the calculated vehicle speed change exceeds the limit value. The control unit normally performs an auxiliary steering operation to provide an oversteer and understeer characteristic and performs an auxiliary steering operation to provide an understeer characteristic in the presence of a failure signal produced when a difference between the new vehicle speed value and the control vehicle speed value exceeds a predetermined value.
