With a cover device for a folding top compartment of a vehicle with a lowerable roof structure, in particular for a hardtop vehicle, it is possible to pivot the roof structure into the folding top compartment arranged behind the rear region in a back part of the vehicle bodywork. The compartment can be closed off with a folding top compartment lid which can be folded up towards the rear. A cover unit with a front cover part, a rear cover part, and two lateral cover parts can close a free space which is formed between the closed folding top compartment lid and the rear region. In order to simplify actuation of the individual cover parts, the front cover part is pivotably mounted on the vehicle bodywork, while the rear cover part is pivotably mounted on the front cover part and each of the lateral cover parts is pivotably mounted on the folding top compartment lid.

A process for greatly improving the color index of polyhydric alcohols, especially trimethylolpropane, by hydrogenation comprises using, in the hydrogenation, an alcohol which has already been purified by distillation. The catalysts used are those conventionally employed in hydrogenations, preferably copper, nickel, palladium or ruthenium catalysts.

A plastic article is formed in an injection mold by injecting molten plastic into the injection mold at an elevated temperature, cooling the plastic from the molten condition to a solid condition, and crystallizing a portion of the plastic by slowing down the cooling of said portion.

The process serves the purpose of producing containers. A heated pre-form made of a thermoplastic material is stretched and inflated with the aid of a gas under pressure for purposes of molding the container. The inflating process is divided into a preliminary blowing period with a gas under a lower level of pressure and into a subsequent primary blowing period with a gas under a higher pressure level. The ratio of the container diameter to the inner diameter is selected to be greater than 4.0. The pre-form has a median wall thickness of greater than 3 millimeters and at least at the beginning of the preliminary blowing phase is provided with a material temperature greater than 70 degrees Celsius. The pre-form at least at the beginning of the preliminary blowing phase in the area to be oriented is provided in the area of its upper surface with a temperature which is at a maximum equal to a medium temperature of the inner surface of the pre-form in the area to be oriented. The temporal duration of the preliminary blowing phase is selected to be less than 1.0 second. During the preliminary blowing phase the pre-form is expanded to at least 50 percent of the volume intended for the finished blown container.

Molded plastic articles are prepared in accordance with the process and apparatus of the present invention. A first mold cavity is filled via a feeding unit in engagement with a first mold cavity with plastic containing a volume expanding agent, the filled first mold cavity and feeding unit are moved away from each other and a second mold cavity and the feeding unit are moved into engagement with each other, the second mold cavity is filled with plastic containing a volume expanding agent via the feeding unit, the plastic is expanded in the first mold cavity via the volume expanding agent while the second mold cavity is in engagement with the feeding unit, and the expanded article is ejected from the first mold cavity.
摘要:
A process for making iron, cobalt and/or nickel base alloys containing rhenium. The process involves melting together the components that form the alloys, at least one of the components being a rhenium master alloy having 30 to 70 wt % rhenium, then casting the resultant melt and allowing the melt to solidify. Possible difficulties such as the formation of rhenium heptoxide are avoided by using a master alloy containing (i) rhenium and (ii) iron, cobalt and/or nickel, instead of sintered rhenium as the rhenium source during the melting step.

An arrangement for adjusting the cylinders in a rotary printing press, in particular the distance between the two cylinder axes of the corresponding cylinders has a first roller ring which is arranged centrically with respect to the one of the cylinder axes of the respective one of the cylinders and a second roller ring radially movable and being arranged on the other cylinder. The second roller ring cooperates with the first roller ring and defines a bore hole of a predetermined diameter. A conical bushing is provided for supporting the second roller ring in the other cylinder and is axially movable with respect thereto so as to adjust the distance between the two cylinder axes. The conical bushing has a largest diameter which is still smaller than the diameter of the bore hole.

The present disclosure is directed to a cover for preventing use of a dispenser. The cover includes a body having an open end, a closed end, and a sidewall extending between the open end and the closed end. The sidewall has an outer peripheral surface and an inner peripheral surface which encompasses an inner space for receiving a dispenser.

A fluid power valve module has a supply port for fluid and at least one fluid power and more especially pneumatic valve able to be controlled via the control interface of the valve module for control of a fluid power instrumentality by way of power ports on the basis of the supplied fluid. There is a provision such that the valve module comprises at least one switching output integrated in its housing for output of a switching signal for switching a switching means for influencing and more especially deactivating the instrumentality.
