Title: Gas/liquid mixing apparatus
Inventor: CASEY ALAN PATRICK
IPC: B05B1/08
Filed: 1993-10-07
Granted: 2004-08-10
Abstract: A mixing apparatus (1, 100) for atomising a fluid in a gas flow. The apparatus (1, 100) has a nozzle (2, 102) which fluidly communicates with a source of liquid, and a gas passage (3, 103) which surrounds the nozzle (2, 102). The nozzle (2, 102) is formed such that it, in use, directs the liquid into the surrounding passage as a substantially continuous, generally radially emanating sheet. As such, the gas flowing through the passage (3, 103) impacts with the liquid sheet to produce a substantially uniform cloud of atomised liquid droplets downstream of the nozzle (2, 102).  The apparatus (1, 100) may further have a reduced cross-sectional area (25, 113) of the passage (3, 103) in the vicinity of the nozzle to increase the gas velocity and enhance the atomisation of the fluid. Further the nozzle (2, 102) may have a valve arrangement to selectably open and close the nozzle (2, 102), and the passage (3, 103) may likewise have a valve arrangement. Furthermore, a swirl mixing (114) of the atomised liquid and gas may be provided downstream of the impact atomisation of the fluid sheet in the passage (3, 103). The apparatus is particularly useful in internal combustion engines, although it is also applicable in any other context requiring a liquid to be atomised in a gas stream.

Abstract: In cutting a film into individual screens and in fitting the screens onto the slide mounts, the positions for cutting the film are correctly set so that the film can be cut easily and quickly.  For this purpose, holes are perforated in an opposing manner in both side portions of the film in a direction in which it is fed.  The film is loaded into the camera, and a line L connecting the centers of the holes is brought into agreement with the center line of a gap portion between the screens.  The film is divided into individual screens when it is cut using a pair of scissors along the lines L that connect the holes of the film.  The ends of the holes in the direction of feed are semicircularly formed.  Therefore, if the film divided into individual screens is brought into engagement with the positioning pins of the slide mount, semicircular portions of the holes and the positioning pins are fitted to each other, and the film is correctly fitted onto the slide mount.

Abstract: Address generators output addresses of transfer data of transfer origin and destination DRAM's.   Updating of the transfer  addresses  from  the  address  generators  during execution of DMA is performed based on a CAS signal from a timing signal generator.   A delay element delays the CAS signal by a time which is the sum of an access time of the transfer origin DRAM and a data set-up time of the transfer destination DRAM.  A transfer data counter counts the number of leading edges of the CAS signal while a RAS signal from the timing signal generator is held active.  When a counted value reaches a preset value,  the transfer data counter outputs continuous data transfer suspension information to the timing signal generator.   With this arrangement, the halt in operation of a CPU due to continuous occupation of a bus is effectively prevented while achieving the increased data transfer rate.

Title: Telecommunications network
Inventor: ARDON MENACHEM TSUR
IPC: H04L12/44
Filed: 1996-04-22
Granted: 1999-12-14
Abstract: This invention relates to arrangements for interconnecting a plurality of stand-alone switches by data and communication channels (the latter typically used for communicating voice signals) in such a way as to make the plurality of switches act as if they were one switch. The invention further relates to arrangements for permitting groups of lines, the groups connected to different stand-alone switches, to be treated essentially as if they were connected to a single switch. Each switch of a symbiotic network (a group of stand-alone switches) or a virtual symbiotic network (the grouping of the groups of lines) accesses pertinent data in its own data base or the data base of one of the other switches of the symbiotic or virtual symbioticnetwork and treats the results of such data base accesses as if they were made internally in the switch. For a symbiotic network the trunks of all the switches of the network going to a common destination (and one such common destination can be any of the switches of another symbiotic network) are grouped into a single group so that an outgoing call can readily be made over a trunk connected to any of the switches of the symbiotic network. Similarly, incoming trunks to any switch of the symbiotic network from a common external source can be grouped into a single trunk group at that external source (which can be another symbiotic network). Advantageously, such an arrangement provides a convenient way of achieving the advantages of a giant switch without requiring the capacity of such a switch andwithout requiring the geographic concentration of traffic necessary to keep the links to a giant switch reasonably short. Advantageously, a virtual symbiotic network provides an economical and flexible solution to the problem of providing services such as wide area Centrex.

Abstract: Disclosed are methods and corresponding apparatuses utilized in the production of ophthalmic lenses, and more specifically for the separation of the corresponding mold halves between which contact lenses are produced. The method to which the several variations of this invention are directed includes: (1) loosening one of the mold halves relative to the contact lens by applying a thermal gradient across the mold and lens, thereby weakening the adhesion therebetween; and (2) subsequent to the loosening step, separating the corresponding mold halves by prying or lifting them apart. There are herein disclosed several embodiments of the invention which achieve these steps in various ways. With respect to the step of loosening the molds relative to the contact lenses by applying a thermal gradient thereacross, there are described devices for directing infra-red energy, steam, or coherent light energy onto the mold half. With respect to the step of separating the mold halves, subsequent to the application of the thermal gradient, there are described devices for prying, rotating and lifting, or purely lifting the loosened mold half away from the other mold half and the contact lens therein. Each of the separating devices include component elements which hold stationary one of the two mold halves as the other is removed.

Abstract: A method and apparatus for supporting the weight of legs, boots, and skis of a skier while riding do a ski lift chair which uses a support strap of elongated flexible material attached at one end to each boot in conjunction with a boot attachment strap. The other end of each support strap extends up the back of a skier's legs attaching to the skier's body above the thigh area. The support strap attaches to either a pull tab, a reel, an elastic strap or an elasticized cord which retracts and draws taut the support strap so as to slightly elevate the skier's legs, boots, and skis and support their weight. Either the weight on the thigh and buttock on the support strap, a gear lock on the reel, or a union between a hook tab which attaches to the support strap and a pile strip which attaches to the ski apparel holds the support strap taut and maintains the legs, boots, and skis of a skier in the elevated position. Thus, the apparatus supports the legs, boots, and skis of a skier while riding on a ski lift chair and eases the strain on the skier's knees and legs.
