Abstract: An item of jewelry has a main body with a first and second end, which, in the closed state, is located opposite the first end. The main body defines a through-opening and the two ends of the main body can be moved away from one another to form a through-opening. The main body has a channel, in which at least one resiliently elastic element is movably arranged. The first end of at least one connecting element is fastened directly or indirectly on the first end of the main body, and which extends over a free space between the first and the second ends of the main body in the open state. When the first and second ends of the main body are moved apart the resulting activation of the resiliently elastic element generates a restoring force which moves the two ends of the main body towards one another.

Abstract: A printing blanket assembly for a blanket cylinder of a rotary printing press includes a dimensionally stable support plate, and a printing blanket fastened to the outside of the support plate. A leading end of the support plate and a trailing end of the support plate are fastened to the blanket cylinder by the provision of an angled or beveled, printing blanket free end. A filler is provided between the beveled end of the support plate and the inner edge of the leading and trailing ends of the printing blanket.

Abstract: A forme cylinder is supported and adjusted in a printing group of a rotary printing press, which group includes a transfer cylinder and a counter-pressure cylinder, which two cylinders include interacting support elements. The forme cylinder does not include a support element which interacts with the transfer cylinder. The forme cylinder has a shaft distance that can be adjusted during printing to adjust a contact pressure between the forme cylinder and the transfer cylinder. The forme cylinder may be covered with a waterless printing forme. The contact pressure between the forme cylinder and the transfer cylinder can be adjusted to a property, such as the compressibility, of the waterless printing forme.

Abstract: A device that is useable to clamp a rotatable shaft or spindle and which is provided with cams or pressure pieces, to retain or to tension packings on a cylinder, is provided. The shaft or spindle can be both rotated about an axis of rotation, as well as clamped against rotation by the device. The device can be pivoted with respect to the shaft or spindle about a pivot axis which is essentially perpendicular to the axis of rotation of the shaft or spindle. The pivotable device can be provided as a pawl or lever that interacts with a pair of stops to hold it in a shaft or spindle locking position.

Abstract: A side impact protection device for an occupant of a vehicle includes a housing fastened on the vehicle body side, a gas generator and an air bag. Within the air bag, a partition is provided which has a blocking effect for the gas flow emerging from the gas generator, and a main through-flow opening is formed on the partition. So that, in the inflated condition, the air bag takes up its ideal operating position, it is provided that, in its mounted position, the air bag is installed so that it is rotated with respect to the gas generator or to the housing, specifically in the opposite direction to the erection moment in effect in the air bag during the inflation thereof.

Abstract: Rotatable shafts that are configured as profiled shafts or as spindles provided with cams or pressure pieces are used to actuate devices for retaining and/or tensioning in cylinders, especially in cylinders or printing machines. Such shafts require in addition to a device for actuating the clamping and/or tensioning device also a locking device for securing them against unintentionally twisting or releasing them and for the defined adjustment of their position. The aim of the invention is therefor to provide a single means for clamping or tensioning as well as locking the shaft. To this end, the device can be swiveled in the peripheral direction of the shaft for tensioning/clamping it, and about an axis that is substantially perpendicular to the swivel axis of the shaft for locking the shaft. For adjusting and fixing a defined position of the shaft (04) and for locking it with respect to its direction of swiveling a pawl (21) interacts with a pair of stops (24,26) in the locking position (A).

The inflating device is formed by an elongated tube generator. The air bag is placed into a narrow elongated storage shape by bringing the air bag into its folded-together position by combined turning and rolling foldings. In its folded-together position, the air bag is held by a surrounding protective cover envelope.

Abstract: A passenger compartment for a passenger car has one B-column on each vehicle body side which leads into a side member situated below the B-column for increasing the transverse stiffness of the passenger compartment in the event of side impact loads. A transversely stiffening tube construction is composed of two laterally exterior upright reinforcing tubes and a tube-shaped stiffening element which extends over the width of the vehicle body. In order to achieve a more favorable introduction of force in the event of a side impact load, each upright reinforcing tube is linked to an adjoining connection plate with a lower edge area which is supported on the exterior side of the side member. An inwardly projecting supporting tube leads away from each reinforcing tube above the elevation of the side member. This supporting tube is rigidly connected in the area of the passenger compartment with one of the outer ends of the transversely extending, tube-shaped stiffening element.

The module is mounted on a door interior panel, with an outlet opening for the inflated gas bag being provided on an upright wall section of door trim located in front. For improved utilization of the existing door cavity and to achieve a rigid connection between the housing and the door interior panel, the housing has a trough-shaped receiving section for the gas generator, an expulsion channel located in front for the gas bag, and a panel-shaped mounting section. The receiving section passes through a recess in the door interior panel and penetrates into the door cavity located behind.

Abstract: A side impact protection device for an occupant of a vehicle includes an air bag which is divided by an interior partition into two chambers situated above one another. The lower chamber interacts with a gas generator. A primary opening having a relatively large cross-section is formed at the partition. So that an optimal functioning of both chambers of the air bag is always ensured during the inflation, at least one other opening with a relatively small cross-section is provided on the partition next to the primary opening situated outside the radiation area of the gas generator. The other opening extends at a distance to the primary opening and acts as a pressure relief valve when the lower chamber of the air bag is inflated.

Abstract: A side impact protection device in the form of an inflatable gas bag for an occupant of a motor vehicle includes an outlet opening located on a vertical wall section of a trim part located in front, said opening being closed by a cover when the gas bag is in the resting position. The cover consists of an external frame part fastened to the adjoining trim part and at least two lid halves that are connected integrally with the external frame part. The pivotable lid halves are provided with a decorative covering on the side facing the passenger compartment. The covering has a tear seam located in front of the common connecting area of the lid halves.

In order to simplify installation costs for the gas bag, gas generator, and restraint, provision is made such that one end of the restraint is connected with the gas generator and the other end is connected with the fabric layer of the gas bag that faces the occupant.

Abstract: Deposits are removed from the end of a spray dampening nozzle which is used to spray pressurized fluid that is delivered to the nozzle end. This fluid is activated by ultrasound before it exits the nozzle end. The activation of the fluid can be accomplished upstream of, or at the nozzle end. An ultrasound vibrator is used to activate the fluid and is either directly or indirectly connected to the fluid by a vibration transmitter.
