Title: Reel assembly
Inventor: LINDEMAN GUNNAR ANDREAS
IPC: B66D1/74
Filed: 1998-10-23
Abstract: A capstan winch (10) includes a reel assembly comprising a reel (12), which rotates, and two generally annular floating flanges (20) which are supported so that the planes in which they rotate converge towards one another, which has the effect of creating an apparent axial movement of the flanges with respect to the reel as they rotate together. The cylindrical surface of the reel (12) is provided with alternating lands (19) and grooves (18) and the floating flanges (20) have formed on them alternating inclined faces (26 and 24) which correspond with lands (19) and grooves (18). The inclined faces (24 and 26) are angled so that the faces (26) which correspond to each land (19) on the reel (12) are generally parallel to one another. The inclined faces (24) which correspond to each groove (18) converge. Consequently, substantial lateral forces are exerted on a cable being wound onto the reel (12) only when the cable overlies the grooves (18) and frictional forces on the cable are minimised.

Title: Method and device for page by page conveyance of a pre-printed striplike recording medium in a printer
Inventor: HOFMANN HOLGER
IPC: B41J11/46
Filed: 1998-11-10
Abstract: The invention relates to a method and a device to control a paper drive-mechanism (8) which is devoid of a sprocket feed in an electrographic printer that outputs data on a pre-printed striplike recording medium (5). Said recording medium (5) has the same optical marking (109) on all pages. In a start operation, the front edge (110) of the recording medium (5) is inputted into an input zone (69) at a specific insert mark (65a), whereupon said recording medium (5) is conveyed by means of a conveyor motor (41, 102) in direction (A) at a given length and at a first relatively low speed. A sensor (59,85) scans a specific area of the recording medium (5) during the conveyance process and transmits scanning signals to an evaluation device (100). The evaluation device (100) examines whether the scanning signals coincide with the marking characteristics (109) and the length of conveyance between two similar successive markings (109) is identified by the evaluation device (100) as a page length value. The printing process is initiated at a second relatively high speed of conveyance and conveyance is controlled according to the identified page length value.

Inventor: WILK DANIEL
IPC: H04M3/436
Filed: 2000-07-07
Abstract: The present invention provides a novel system, method and apparatus for answering a telephone call. In one aspect of the invention, there is provided a system for call answering that includes a switch for connecting a telephony device to incoming calls received from callers connected to the switch via a telephone network. The switch is also connected to a processing unit and a storage device that contains a plurality of pre-recorded messages. When a callee at the telephony device receives an incoming call during a meeting (or at some other inconvenient time) and yet the callee wishes to respond to the caller, then the callee can provide (via a keypad on the telephony device) message selection criteria to the processing unit. The processing unit can then assemble an outgoing message based on the message selection critiera. The message is assembled from from the plurality of messages saved on the storage device. Having assembled the message, the processing unit can then play that outgoing message to the caller. In this manner, the callee is afforded a way to discretely respond to the caller without having to interrupt the meeting (or other activity that makes it inconvenient for the callee to answer the call.)

Inventor: CHIAN BRENT
IPC: F23N5/10
Filed: 2000-12-01
Abstract: An apparatus for and method of generating a useful electrical output within a system employing a flame. A thermopile receives heat energy from the flame and generates electrical power. This electrical power is converted to a higher voltage by a special low voltage DC-to-DC converter which operates shortly after ignition. During steady state operation of the flame, a second DC-to-DC converter produces a higher voltage output from the thermopile output. However. the second DC-to-DC converter provides both regulated and unregulated outputs, and regulates the input voltage to keep the valves in the ON state and achieves maximum output power from the thermopile.

IPC: C22C1/02
Filed: 1999-05-14
Abstract: L'invention concerne un procédé et un appareil pour ajouter un métal, comme du sodium, à un bain d'un matériau en fusion, par exemple, de l'aluminium dans une cuve. Selon ce procédé un composé fondu du métal ou une solution d'un composé du métal sont placés dans un conteneur (12) à l'extérieur de la cuve. Ce composé se décompose par voie électrolytique ce qui provoque le passage des ions de métal à travers une paroi d'un électrolyte (14) conducteur à l'état solide, depuis un premier côté de la paroi jusqu'à un deuxième côté opposé de cette dernière. Les ions de métal vont alors se combiner aux électrons au niveau du deuxième côté de la paroi, et vont s'écouler sous forme d'un métal fondu pour passer du conteneur dans le bain de fusion dans la cuve.

Title: Valve gating apparatus and method for injection molding
Inventor: MAI ARNOLD
IPC: B29C45/16
Filed: 1999-02-15
Abstract: A valve gating apparatus and method for injection molding includes at least one shutter disposed between the gate and the cavity melt channel into a mold cavity. The shutter is moved laterally, between a closed position wherein flow of melt from the nozzle into the cavity is inhibited, and an open position wherein flow of melt into the cavity is unimpeded by the shutter. Intermediate these two positions, the shutter can be employed to reduce the cross-sectional area of the gate to throttle the gate. Embodiments are disclosed wherein one shutter or pairs of shutters are employed to gate the gate. Further, when pairs of shutters are employed, the shutters can abut each other in the close position or can overlie each other. This novel design prevents generation of waste material and eliminates the need to have means for removing cold plugs.
