Inventor: GRAF WALTER
IPC: F16N11/10
Filed: 1994-08-29
Granted: 1999-04-06
Abstract: A cartridge containing a current-generating cell and a gas-generating cell electrically connected therewith is received in a cylindrical seat of a bottom part of a unit fitting into an end of a lubricant receptacle housing and closing this end thereof.  The lubricant receptacle housing can be connected by a fitting at the opposite end to a machine to be lubricated.  The unit has a cover cap on its bottom part which can be forced off the latter when gas is generated in the unit and displaced in the receptacle to force the lubricant out of the housing. The result is a lubricant dispenser which is inexpensive to manufacture, efficient to operate, reliable and at least partially reusable.

Abstract: A circuit for correcting errors in a received complex data signal including a synchronous detector for recovering an in-phase data component from the received signal and a Hilbert transform filter for estimating the related quadrature component from the recovered in-phase data component, the recovered in-phase data component including a periodically recurring reference signal. A decision feedback loop is periodically operable in response to the reference signal for initially error correcting a selected characteristic of the received signal at a first relatively rapid rate and for subsequently error correcting the selected characteristic at a rate which is less than the first rate and which is dependent upon the estimated signal to noise ratio of the received signal. In one embodiment, phase errors are corrected at a rate which is also directly related to the value of the estimated quadrature component.      In another embodiment, amplitude errors, e.g. gain and offset, are corrected at a rate which is inversely related to the value of the estimated quadrature component.

Abstract: In a video teleconferencing apparatus, line interfaces are connected to communication channels for receiving data-compressed integrated frame format signals from an adjacent video teleconferencing apparatus. Each of the integrated frame format signals contains the respective video frames of user terminals. Data decompression decoders are respectively connected to the interfaces for decompressing the data-compressed integrated frame format signals to produce data-decompressed integrated frame format signals. A controller, connected to the interfaces, receives control signals from the channels and produces an address signal. Extraction circuits are respectively connected to the decoders for extracting desired video frames from each of the data-decompressed integrated frame format signals in accordance with the address signal. The output signals of the extraction circuits are integrated by a video integrator and data-compressed by an encoder for transmission via the interface.

Abstract: A floor, wall, roof, or ceiling of a building is made of specially adapted beams and overlying panels. The beams have a layer of foam material on their edges. The foam material can include a resiliently compressible material, a thermally insulating material, or a material which possesses both of these properties. The panels are positioned over the beams so that the foam material is sandwiched between the beams and the panels.      When the panels are fastened to the beams, the resiliently compressible foam material partially compresses, thereby filling any gaps which may form between the beams and the panels. The resiliently compressible foam material thus prevents relative movement between the panel and the beams which would otherwise produce squeaks. When the foam material includes thermal insulating material, it forms a thermal barrier between panels and beams, especially metal beams, thereby eliminating various drawbacks of construction using metal beams.

Abstract: The invention relates to an electically powered winding and reeling mechanism for underwater use by divers. It consists of a drive shaft assembly having connected to one end thereof a spool with a cord wound thereon. The shaft assembly is sealingly pressed into one smaller end of a main housing. A gear reduction unit with attached motor, a 3-position switch (forward,neutral, reverse) and batteries are positioned as a unit into a larger opposite end of the main housing so that the drive shaft of the assembly mates with the gear reduction unit. The larger end of the housing is sealed by a threaded end cap and o-ring seal. The gear reduction unit is driven by the motor, power to which is supplied by the batteries under control of the 3-position switch ; the latter is actuated by an outer switch lever extending from the housing and sealed therefrom. The spool can therefor be rotated in either a forward or reverse direction or be allowed to rotate freely depending on the position of the outer switch lever, which controls the 3-position switch. With the switch in the neutral position, a lock/release lever disconnects the drive shaft from the spool to allow the latter to rotate freely.

Abstract: Process for recovering chemicals and energy from black liquor, where the black liquor is gasified with CO, CO2. CH4, H2, and H2S, in gaseous form, and Na2CO3, NaOH and Na2S, in the form of drops of smelt, being principally formed. The mixture of gas and smelt is cooled, in a first stage, by direct contact with a cooling liquid, whereupon a part of the cooling liquid is volatilized, and the smelt drops are separated off and dissolved in the remaining part of the cooling liquid with the formation of a liquid bath (6) of green liquor. In a second stage, the gas is washed and saturated with moisture by direct contact with a washing liquid bath (13). After the gas has been washed in the second stage, energy in the form of thermal energy and condensation heat is recovered from the gas in an indirect condenser (16). The contact between the gas and the liquid bath (6), consisting of green liquor, in the first stage is substantially less than the contact between the gas and the washing liquid bath (13), in the second stage. This is achieved, by the gas in the first stage not being permitted to bubble through the liquid bath (6), consisting of green liquor, in contrast to the second stage, in which the gas is caused to buble through the washing liquid bath (13).

Abstract: An on-machine-seamable (OMS~) papermakers' fabric produced by modified endless weaving includes machine-direction (MD) and cross-machine direction (CD) yarns.      The MD yarns are plied/twisted yarns, and weave continuously back-and-forth between the two widthwise edges of the fabric, each time forming a seaming loop at one of the two widthwise edges. A seaming spiral, a monofilament spiral preferably extruded from a polyamide resin, is attached to the seaming loops at each of the two widthwise edges. The two seaming spirals are used to join the fabric into endless form with a pin seam. In this manner, the invention provides a further approach to making on-machine-seamable PMC with plied, twisted or plied and twisted yarns.
