Abstract: A method and a packet network in which a transmitting user unit in the network transmits an information sequence either to one selected receiving user unit or commonly to a selected number of receiving user units. An information sequence is a data cell that is divided into a header and an information-carrying part. The data cell header includes a bit configuration that represents a destination address, while the information-carrying part includes a bit configuration that represents relevant information. The bit configuration in the data cell header is interpreted in accordance with the logic value of an indicated status bit, which is included in a bit field separate from the bit field that accommodates the actual address-dependent bit configuration.

An elongated transport car for supporting an assembled track section and the hoisting device is movable in this direction independently of the hoisting device. The elongated carrier frame and transport car each are comprised of two parts connected by a pivot between their opposite ends for pivoting the parts relative to each other about a vertical axis.

Abstract: An infrared communicating badge is provided for transmitting an infrared coded signal, such as a patient identification number. The badge includes a sealed housing having an infrared transparent segment. The badge housing contains a power source, a microprocessor, an infrared transmitter, and an infrared receiver. The badge receiver is desensitized such that it does not respond to ambient light from the surroundings and, preferably, only detects signals from a programmer. This programmer transmits a coded infrared signal, which represents the patient identification number, to the badge. After the coded infrared signal is transmitted and stored in the badge, the infrared signal is transmitted periodically to another infrared receiver, located in a remote location. The remote receiver relays the information to a base unit at which the location of a person may be monitored.

Abstract: A system for launching a lifeboat (11) from davits (12) on an offshore drilling platform (10) comprises a submerged buoyancy device (10) tethered to the bow of the lifeboat (11) by a cable (13) which passes between the buoyancy device and the lifeboat. The cable is retained by a release mechanism (14) attached to the platform just above the water line and extends upwardly from a guide fairlead (18) attached to the sea bed, between the latter and the lifeboat (11). In some cases the release mechanism (14) may be omitted or alternatively two release mechanisms may be provided above the water line.

Abstract: A trimming apparatus (10) for removing the dome scrap (152) from a blow, molded bottle (150) is described. The apparatus includes an advancement wheel (12) and a rotation wheel (14) mounted on opposite sides of a path (16) formed by upper guide rails (18 and 20), lower guide rails (22 and 24) and the wheels. A knife assembly (62) is adjustably mounted beneath the advancement wheel and includes a knife blade (64) which extends into the path slightly in front of the area tangent to the wheels. The wheels are connected to drive motors (26 and 28). In use, the bottle is fed into the path such that the upper guide rails engage each side of the groove (152A) of the dome scrap. As the bottle moves into the apparatus, the advancement wheel engages the groove to move the bottle into the path between the wheels. When the bottle reaches the area of the path tangent to the wheels, the rotation wheel contacts the groove.
