Patent WO-9320946-A1 (WO)
Title: Apparatus for separating materials
Inventor: WOOD WARWICK NASH
IPC: B04B1/04
Filed: 1993-04-08
Abstract: Material separating apparatus comprising a rotatable main body (13) and a rotatable rotor (14) disposed within the main body. The rotor (14) comprises first and second end walls (16, 17) spaced apart from one another with a rotor chamber therebetween, with a plurality of generally radially extending blades (18) extending between the first and second end walls thereby separating the rotor chamber into a plurality of sub-chambers. A feed inlet chamber is disposed between the main body and the first end wall. The end walls have a circumferential clearance for permitting the flow of material into and the discharge of the heavier component out of the rotor chamber. A generally centrally disposed discharge is in communication with the rotor chamber for discharging the lighter component from the rotor chamber.

Inventor: CHAN SAMMY CHI HUNG
IPC: H04L12/54
Filed: 1993-11-12
Abstract: Un procédé et un appareil conçus pour évaluer le trafic dans un réseau de télécommunicatons asynchrones, fournit des évaluations en temps réel et peut être conçu pour s'adapter à la vitesse des variations dans le trafic entre des cellules. Des boucles itératives synchrones accumulent les arrivés de cellules détectées et les temps entre ces arrivées, l'accumulation des valeurs précédentes étant modifiée par un facteur de réponse. Un rapport entre les sorties des boucles synchrones peut être calculé de manière asynchrone pour fournir une évaluation du trafic entre les cellules. Les sorties de deux évaluateurs utilisant des facteurs de réponse différents peuvent être verrouillées selon les changements détectés dans le trafic entre les cellules de manière à fournir soit une réponse lente mais précise, répondant lentement aux variations dans le trafic, soit une réponse rapide mais perturbée par des bruits.

Title: Method for controlling of ac semiconductor switch
Inventor: ANGELOV ANGEL G
IPC: C03B5/24
Filed: 1988-06-21
Abstract: This method is used in electric power supply systems for glass kilns. It ensures the elimination of current surges in the load transformer by retaining control over power transmitted to the consumer. This method is unique in that the interval of the initial phase angle is between 0 and 90 degrees, following with which the switch turns on when the current passes through the neutral, and turns off upon reaching an even number of half-periods.

Title: Procede, systeme et appareil permettant de transmettre des donnees entrelacees entre des stations
Inventor: MANTHA RAMESH
IPC: H04J13/00
Filed: 2002-07-19
Abstract: L'invention concerne un système permettant de transmettre des données entre des stations, par exemple des stations de base et des stations d'abonnés dans un système de télécommunications sans fil, qui utilise un ensemble de paramètres d'entrelacement variables pour ses opérations d'entrelacement. Grâce à un ensemble de paramètres d'entrelacement différents utilisés dans des dispositifs d'entrelacement, des données qui seraient alignées lorsqu'elles sont transmises d'une station vers plusieurs stations, ou de plusieurs stations vers une station, ne sont pas alignées après l'entrelacement, ce qui permet de réduire le rapport valeur de crête/valeur moyenne d'énergie requis pour transmettre des ensembles de symboles de code à partir d'un émetteur et/ou de réduire une interférence au niveau des récepteurs du système. Cela est particulièrement vrai lorsqu'une une partie significative des signaux alignés sont des symboles de code requérant une puissance nulle pour être transmis.

Title: A method of preparing thin layers of conductive polymers
Inventor: WESSLING BERNHARD
IPC: H01B1/12
Filed: 1989-10-11
Abstract: Process for producing preforms of intrinsically conductive polymers used as conductive laminated components, with a specific conductivity > 1 10<-2>S/cm, and which can contain other materials as substrate. In said process, the conductive component is built up by separation from a metastable dispersion of the intrinsically conductive polymers. Preferably, the conductive component is separated without current from the dispersion as a layer on the substrate. For implementing the process, a dispersion of insoluble organic polymers, which are given an electrically conductive form by oxidation agents or by acids, in an aqueous or organic medium with a solubility parameter  >/=  8.6 [cal/cm<3>]<1/2>, which can be filtered without decoloration through a press filter with a pore width of 250 nm, is suitable.

Title: Mould and method for the manufacture of moulded objects of plastic
Inventor: RASMUSSEN TORBEN
IPC: B29C51/36
Filed: 1989-10-24
Abstract: Manufacture of moulded objects of plastic.            ABSTRACT     Moulded objects of plastic are moulded by the  placing of a sheet, or a layer of plasticified material by suction a-gainst the outline-forming outside of a mould which is per-meable to let a gaseous working medium influence the mate-rial through the material of the mould. Prior to this in-fluence a mould is manufactured which at least for the out-line-forming part of the  mould consists  of a particular composite material, whose particles are bound together for the creation of a form-stable exterior structure having air passages extending to the outside of the mould. The suction is then carried out on the mould thus created.

Title: Mechanical expansion anchor
Inventor: WRIGHT RAYMOND L
IPC: F16B13/06
Filed: 1990-04-17
Abstract: An improved, radially expansible shell for use in a  mechanical expasion anchor and an anchoring system including such a shell  in  combination  with a resin grouting mix, in a drill hole of predetermined diameter. The shell includes a plurality of leaf portions having internal surfaces for engagement by a tapered camming plug as the shell is expanded, external surfaces having a maximum diameter less than that of the drill hole, and side edges.  A row of tapered teeth extends outwardly from the external surface of each leaf along one of the side edges thereof.  The distance from the central axis of the shell to the crests of the teeth is substantially equal to the radius of the  drill hole.  The teeth frictionally engage the drill hole wall to retard rotation of the shell and ensure the desired expansion.          When the anchor  is   used  with  a   conventional, two-compartment resin  package,  the  resin components may flow around the shell into the annular space between the external surfaces of the leaves and the drill hole wall.

Abstract: EFFICIENT CONNECTION ARRANGEMENTS        FOR MULTIHOP NETWORKS Abstract This invention is a Local Area Network (LAN) which comprises a plurality of NIU's, each arranged to transmit on a separate set of frequencies and to receive on a separate set of frequencies. During operation, a data packet is multihopped from a source NIU, through intermediate NIUs, until reaching an NIU which can transmit a frequency which the destination NIU is capable of receiving. The packet is then forwarded to the destination NIU. The source NIU may also send a control packet and cause the destination NIU to adjust its receive frequency so that subsequent packets may be transmitted directly to the receiving NIU. In an alternative embodiment, the multihopping may be accomplished using specialized headnode modems.

Title: Method and apparatus for simulating open flame broiled meat products
Inventor: RAO MOHAN
IPC: A23L5/10
Filed: 1990-07-06
Abstract: ABSTRACT         The specification discloses an apparatus for rapidly cooking meat products for a quick service restaurant which will simulate the appearance of an open flame broiled meat product.  The meat product is clamped between a grill and a series of raised crown portions formed in a cooking pan.  The cooking pan also includes rounded depressions which alternate with the upraised crowns to serve as reservoirs for the collection of fat and other rendered meat juices.  The clamping action between the grill and the pan compresses the meat product having a range of product weight to a uniform thickness while simultaneously assuring conductive heat transfer from the crowns to the meat and radiant heat from the black body pan to the meat.  The grill is pre-coated with a carmelizing agent which leaves grill marks on the meat product during the cooking cycle.  The grill, meat product and pan are loaded into a convection oven having means for creating heated high velocity convecting air which contacts the meat product, displace a food product boundary layer of cool air, and evenly heat the irregular surface of the meat product as heated air passes over it.
