Title: Flat plate antenna
Inventor: TWELVES ALAN
IPC: H01Q21/06
Filed: 1991-11-20
Granted: 1995-08-30
Abstract: A dual polarised flat plate antenna (10-38) has a single circular waveguide output (44-48) accommodating probes for both polarisations. A low noise block (58) has a complementary single circular waveguide input (56) and is rotatably attached to the antenna. The low noise block input couples with both probes to feed a common low noise block circuit. Rotation of the low noise block relative to the antenna provides continuously variable polarisation. <IMAGE>

Title: Atomisation of liquids
Inventor: ROWLAND STEPHEN JAMES
IPC: B05B3/08
Filed: 1994-03-04
Granted: 1996-11-27
Abstract: The invention relates to the atomization of liquids. There are many fields of application where a spray mist or jet of fine droplets is required and where control over droplet size is important. Of particular significance is the medical field and the nebulizing of a drug to be administered to a patient by the inhaled route, where the deposition of the drug and its efficacy is a direct function of the droplet size. The object of the invention is to improve the control over droplet size, an objective met by a method and a construction where liquid is centrifugally forced between the plates forming a rotor, secured together with a spacing to provide an annular orifice or held together in abutting relationship with an ability for pressurized fluid to pass between the plates, the rotation of the rotor causing the forcing of the liquid through the orifice or between the plates and such that the centrifugal force and the Bernoulli effect causes the liquid to issue in the form of droplets of a predetermined size.

Title: System and method for extended enterprise planning across a supply chain
Inventor: BELLINI JOSEPH M
IPC: G06Q10/00
Filed: 1997-01-30
Granted: 1998-10-07
Abstract: A system for extended enterprise planning across a supply chain is provided. The system includes transactional execution system layers (14,18) for a demand enterprise (10) and a supply enterprise (12). First and second federated electronic planning interchange layers (16, 20) provide a data specification format and an external communication interface for transactional execution system layers (14, 18). A supply chain planning engine (22), operable to perform planning for the supply chain, is in communication with a third federated electronic planning interchange layer (24) which provides a data specification format and an external communication interface for the supply chain planning engine (22). A data access/transfer layer (28) interconnects and allows transfer of information between the first, second and third electronic federated planning interchange layers (16, 20, 24). The supply chain planning engine (22), the first transactional execution system (14) and the second transactional execution system (18) can thereby communicate data which the supply chain planning engine (22) can use to provide constraint based extended enterprise planning across the supply chain.
