Title: Improved call set-up in a radio communication system with dynamic channel allocation
Inventor: STRAWCZYNSKI LEO
IPC: H04W24/00
Filed: 1991-10-04
Abstract: A call set-up technique which uses channel selection at both base (11) and subscriber terminal (13) in determining the radio traffic channel upon which to set-up a new call. Communication between the base station and subscriber terminal is carried out on a signalling channel until the traffic channel is chosen. Calls are set-up so that they proceed on the radio channel which, of a set of channels under consideration by the subscriber terminal, contains the least amount of interference as measured at the subscriber terminal. The channels under consideration by the subscriber terminal are those channels having little interference, as measured by the base station. The call set-up technique thereby assures that calls proceed on channels containing little interference from the viewpoints of both base station and subscriber terminal. (Fig. 1). <IMAGE>

Title: Automatic flushing device
Inventor: CHIOU TZENG-SHYANG
IPC: E03D5/10
Filed: 1991-11-15
Abstract: A water and energy efficient automatic flushing device 3 is used to control water flow from a water inlet pipe 22 to a flushing conduit 21 of a plumbing fixture, such as a toilet bowl 2. The flushing device detects the presence of a person by omitting coded light pulses, and initiates a first flushing action after confirming that the plumbing fixture is in use. A second flushing action is initiated after verifying that the person using the plumbing fixture has departed. The receiver (42) can distinguish if a received signal was reflected by a person using the plumbing fixture or by a hand that was placed directly in front of the detecting unit 40. Upon confirmation that the received signal was reflected by a hand, the control circuit initiates a hand activated flushing action and flushing is terminated when the hand is removed. if the previous user has departed within the previous three minutes, the first flushing action is inhibited. <IMAGE>

Title: Mechanical seals
Inventor: CARMODY CHRISTOPOHER JOHN
IPC: F16J15/34
Filed: 1992-10-06
Abstract: A sleeve 23 for a cartridge-mounted mechanical seal is formed from two connected-together metallic components. The first component is made from a material having a relatively high chemical resistance, the second from a material having a relatively lower chemical resistance. The arrangement of the components is such that, in use as part of a seal the sleeve has only its first component in contact with the fluid whose escape is being sealed. Such a sleeve is easier and cheaper to produce than one made entirely from a high chemical resistance material, and yet just as effective in use. The invention also provides a seal including such a sleeve. The first component is preferably made from a high nickel-content alloy or titanium. The second component is conveniently made from stainless steel. The two components may be connected together by welding, shrink-fitting or by means of bolts. <IMAGE>

Title: Connector for sealing stacked filter elements
Inventor: CONNORS JR JAMES T
IPC: B01D29/21
Filed: 1993-03-18
Abstract: A connector 60 closes the upper end of a tubular filter element 10, which is the upper one of a stack of such elements, and transmits axial pressure to the stack when a spring 28 is compressed by the housing lid 32. Connector 60 is a disc with a central upstanding ferrule 63, which engages the spring 28, and concentric ridges 64 on its lower face which seal against an annular gasket on top of the filter element. Resilient arcuate latch means 24b and 65b on the filter element and connector make a snap connection when the connector is pushed axially on to the filter element. The male - female arrangement of latch means shown may be reversed, and the gasket may be secured to the connector 60 instead of the filter element as shown. The filter elements of the stack all latch together in the same way as the connector and top element. <IMAGE>

Title: Measurement of interfacial surface tension
Inventor: DOBSON DERRICK CLIFFORD
IPC: G01N13/02
Filed: 1993-03-19
Abstract: The interfacial surface tension between two immiscible liquids is measured by taking a sample of one liquid into a vertical capillary tube 5 whose lower end is then immersed in a body of the second liquid 12. The top of tube 5 is connected to a large closed volume of air 1, a pressure monitor 10 able to measure pressure to an accuracy of 0.01 m Bar and to a syringe 2 whose plunger 4 is movable by a screw to vary the pressure in system 1, 5, 10. The pressure is thus varied while the meniscus at the lower end of tube 5 is observed. The pressure difference recorded between two states, when the meniscus is flat and when it is hemispherical, divided by the capillary tube radius gives a measure of the surface tension. Tube 5 is glass with a circular section bore and a square section exterior, the outer surfaces and the end being optically flat. The bore is 0.5 mm diameter. The meniscus is observed through windows in vessel 13 using a lens system or-TV camera. The temperature in vessel 13 is controlled by means 14. In Fig. 2 the vessel is closed and the pressure monitor records the difference between pressures inside the capillary and inside the vessel above the liquid level. By measuring the surface tension between an oil sample and aqueous solutions containing various amounts of surfactants, a graph is plotted whose trough indicates the HLB requirement of the oil, enabling a suitable surfactant to be selected for making an oil-water emulsion. <IMAGE> .t

Title: Security device
Inventor: WOOD GRAHAM
IPC: E05C19/00
Filed: 1993-05-07
Abstract: The security device is arranged to selectively permit or inhibit full opening of a closure panel (such as a door, window or the like) hingably mounted to a structure. The device comprises an abutment member 6 connected at hinge means (either directly or by means of interconnecting elements) to a mounting element securable to the structure. The mounting hinge axis of the closure panel and the hinge means are spaced in a direction transverse to their axes such that as the closure panel pivots on its hinge axis (when opening) relative sliding motion occurs between the panel and the abutment member. Stop means 3 is selectively positionable on the closure panel in the path of the abutment member such that at a predetermined extent in opening the panel the abutment member engages the stop means preventing further opening of the closure panel. <IMAGE>

Title: Wide area network interface for a transmission control protocol/internet protocol in a local area network
Inventor: HIRVINIEMI SEPPO
IPC: H04L29/12
Filed: 1993-05-28
Abstract: The invention relates to a method for interfacing a TCP/IP software designed for a local area network (LAN) to a wide area network (WAN) via a Media Access Control (MAC) manager. The TCP/IP software uses a lower-level Address Resolution Protocol (ARP) to adapt physical network addresses to logical IP addresses, and a lower-level IP protocol to transfer useful traffic in IP data packets. The MAC manager of the wide area network (3) simulates operation complying with the ARP protocol towards the TCP/IP software, and transmits and receives only IP data packets over the wide area network (3) in a manner specific to the wide area network. <IMAGE>
