Narrow aisle truck that on each side includes two forwards extending support legs (1, 2), which each are provided with two support wheels (4, 5). The two outer support wheels are displaced somewhat to the rear in relation to the inner ones and in the corner space outside the inner ones and in front of the outer support wheels lateral guide wheels (6) are arranged.

A security system for a vehicle includes a transmitter for transmitting an alarm signal to a receiver carried by the driver, rather than automatically actuating a siren on the vehicle. The driver may then remotely actuate the vehicle siren or remotely cancel the alarm signal. If the driver does not respond then the alarm signal is sent to a central station. The receiver may take the form of a mobi...

The present invention relates to an alarm system for a building or a vehicle which is capable of detecting an intruder comprising: a control unit capable of being activate or deactivated; at least one sensor connected to the control unit capable of detecting an intruder; a control system connected to the control unit for activating and deactivating the control unit; the control unit, when activate...

The invention concerns a terminal block comprising an insulating box and a connecting device for an insulated conductor (8), connected by elastic return, without stripping, between a cutting edge (6) and an opposite support. In order to maintain a slight width in the junction direction, the cutting edge (6) extends in said direction, the conductor being inserted, in its connecting position, in its...

A method of recovering a decomposition product from a polyurethane, the method comprising the steps of thermally decomposing a polyurethane into a liquid containing a polyol and a urea compound which is soluble in the polyol, and solids containing a urea compound which is insoluble in the liquid in the presence of a polyamine compound at a temperature of 120 to 250 DEG C; removing the solids; hydr...

A surgical system that applies electrical energy to obtain predetermined surgical effects while improving the control of the application of the energy that is supplied by electrosurgical generators. In one embodiment, a surgical assembly interfaces with and receives power from an electrosurgical generator for executing a first electrosurgical procedure. This surgical assembly may employ a shunt ci...

A pneumatic tire comprising a tread portion (4), a pair of sidewall portions (6) and a pair of bead portions (8) is manufactured by conducting the venting in a portion of a green tire (3) placed in a vulcanization mold (1) prior to vulcanization and corresponding to the sidewall portion in at least one place in a radial direction of the tire during the vulcanization. The vulcanization mold (1) com...

A pneumatic tire is highly precisely and efficiently manufactured by a method wherein, during formation of a green tire, at least one constitutive member, such as a sidewall (17), is formed by radially outwardly expanding a widthwide center portion of a substantially cylindrical carcass band (13), and subsequently winding an unvulcanized rubber strip (14) and joining the rubber strip onto an outer...
