Title: Large round baler having wrapping mechanism for placing net over edges of bale
Inventor: LEIBER YUVAL
IPC: A01F15/07
Filed: 1998-09-08
Abstract: A large round baler includes a net wrapping device mounted to the rear and bottom of the discharge gate of the baler. A spare roll of net material is stored above an active roll of net material which rests upon and is caused to be rotated by the upper roll of a pair of net material feed rolls. The rolls of material are wider than the baling chamber of the baler and net spreader rolls, including both raised spirals and spiral grooves, are provided along the net feed path so that the net is at its full width when it arrives at the inlet to the bale chamber which is located at a lower bale-forming belt support roll extending between opposite sidewalls of the gate at the lower front of the gate. A pair of guide plates are mounted to the insides of the bale chamber sidewalls and extend about an upper portion of the circumference of a net spreader rolls located at the opposite ends of the belt support roll. These guide plates are shaped and positioned such that they perform the functions of creating a space between the bale end and the side wall for receiving marginal portions of the net, defining together with the side walls, a channel which leads from the net spreader rolls to the space created for receiving the net, rounding the end edges of the bale for better reception of the marginal portions of the net and deflecting crop material away from the spirals of the net spreader rolls so as to prevent them from wrapping with crop which would interfere with the feeding of the marginal portions of the net to be placed over the edges or corners at the opposite ends of the bale. First and second alternate embodiments respectively have only the recess or the entire shape of inner surfaces of the guide plates formed into the sidewalls. In the latter case, openings are provided in the sidewalls adjacent the trailing part of the formed shape, as considered relative to the direction of rotation of a bale engaging the formed shape.

Title: Detection method for the transmitter identification information signal in the null symbol of a dab stream
Inventor: ZUMKELLER MARKUS
IPC: H04H60/51
Filed: 1998-09-04
Abstract: A DAB stream starts with a so-called null symbol for the receiver synchronizatio n carrying a transmitter identification information, i.e. TII, signal. Each transmitter in the single frequency network is assigned a main id and a sub id for unique identification. This identification is mapped to a certain pattern with 16/8/4/2 set carrier pairs in the spectrum of the null symbol according to the DAB modes I-IV. Based on mode II which has 384 valid carriers a so called comb block is defined. For modes I and IV this block is repeated 4 and 2 times, respectively. For mode III only a half block is available. This pattern i s transmitted every 2nd DAB frame in the null symbol. To detect the set carriers the steps of differential demodulation of TII pairs included in the spectrum (S1(.omega.)) of every second null symbol of the incomi ng DAB stream (S1, S2, S3) to respectively obtain a demodulated null symbol, correction of carrier phases of the demodulated null symbol spectrum (S4), determination of a threshold (S7), and decision if a carrier is set or not by comparing the carrier level to the determined threshold (S6) are performed.

Title: Method and apparatus for constructing stable iterators in a shared data collection
Inventor: CAVANAUGH KEN M
IPC: G06F9/44
Filed: 1998-12-04
Abstract: In a distributed object system, a stable object iterator provides a list of all persistent objects within a collection of objects. A plurality of iterators are supported in another aspect of the invention. An iterator associates a label with each persistent object in a collection of stable objects. The label indicates whether the associated object was added to or deleted from the collection before or after the inception of an iterator. Multiple persistent iterators are supported by providing an indication of which iterators each persistent object is, or is not, "visible" to. Should an element of the persistent object collection be created after one or more iterators is created, that element is "invisible" to those iterators. Objects that exist when one or more iteratorsare created remain "visible" to those iterators, even if the object is deleted from the collection while those iterators still exist. The system maintains an indication of all extent iterators and of maximum and minimum iterator identifiers which respectively correspond to the most recently created and least recently created iterators.

Title: Method and apparatus for providing voice assisted call management in a telecommunications network
Inventor: GUPTA ROHIT N
IPC: H04M15/00
Filed: 1999-03-23
Abstract: This invention provides a novel switch for use in a telecommunications network that is capable of interacting with a voice assisted services server, such as a voice activated dialing (VAD) server. The switch is configured to set-up a calling session between an originating terminal and the VAD server that creates a voice connection between the user at the originating terminal and the VAD server, the voice connection passing through the switch. The VAD server can then in response to a spoken utterance indicative of the party the user wishes to call, generate a transcription of the utterance and extract from a database the telephone number associated with this transcription. The VAD server then formulates a call session redirect message in which is embedded the telephone number of the party the user wishes to call. This call session redirect message is received by the switch and the command implemented such that the call session is redirected toward the desired location. After this procedure is completed, the connection between the switch and the VAD is released. The invention also extends to a novel voice assisted services server capable of remotely effecting call management at a switch based on a spoken utterance conveyed to the voice assisted services server over a voice connection. Further, the invention also extends to methods for operating a switch and a voice assisted services server to implement the above described functionalities. Yet, the invention also extends to a novel method and apparatus to effect billing operations allowing to differentiate for a single call session the part of the call session involving the voice assisted services server and the part following the call session redirect event.

Title: Heat exchange element for a film heat exchanger and a method for manufacturing the same
Inventor: RAMM-SCHMIDT LEIF
IPC: B29C51/10
Filed: 1998-01-19
Abstract: The invention relates to a heat exchange element (1) for a film heat exchanger intended for distillation or for the evaporation of solutions or suspensions, and to a method for manufacturing the same. The substantially bag-like element is formed by bonding from oppositely positioned plastic heat exchange films (2), evaporation of liquid taking place on the exterior surfaces of the films and condensing of the obtained vapor taking place on the interior surfaces. In the bonding the interior (4) of the element is divided into ducts to direct the travel of the vapor, and according to the invention the films are at the same time stretched in the intervals between the bonding points (3) in order to provide leeway for bulging during the pressurization of the interior of the element. The element (1) may be made up of two heat exchange films (2) stretched by means of heat and a pressure differential between the different sides of the film, the films being bonded directly to each other, or there being bonded, between the heat exchange films to be stretched, one or more straight support films to improve the loadbearing capacity of the element.
