Abstract: A liquid feed bottle for an infant having a body made from a container portion bonded to a teat with an orifice. The body holds a liquid feed such as milk. A cap is bonded or sealed to the body and protects the teat. A cap portion is initially detachable from the body by pulling and removing a tear strip, the cap portion thus released being subsequently securable on the body by a press fit.

Abstract: A new packet filtering system associates domain identifiers with respective sets of addresses. A set of domain prefixes defines the set of addresses associated with a given domain identifier. Domain prefixes are found matching the source address and destination address of each received packet. These prefixes are associated with a source domain identifier and destination domain identifier respectively. The system similarly associates sets of one or more protocol types and port ranges with respective protocol domain identifiers. The protocol type, source port and destination port of the received packet determine source and destination protocol domain identifiers for the received packet. The system includes a filtering matrix including one or more entries, each indicating whether an associated received packed should be filtered.

Abstract: Provided are a system and method for supporting communication between application programs and the processing of messages by those programs. A table driven approach is used to select appropriate components of modular application programs to process received messages. The selection is carried out in dependence on associations between message types (e.g. request, inform, reply) and other characteristics of the message (e.g. whether the message is an expected reply (as identified by an identifier value). Also used in said selection are dynamic characteristics of the message or the system (e.g. possibly expiry of a timeout, or the state of an application). Rules combine these criteria and determine the conditions for invoking an application program component.Also provided is a mechanism for differentiating between reply messages which are received out of serial sequence but are still current and messages which are invalid.

Abstract: Mixtures of at least two of the macrocyclic musk fragrances hexadecanolide, cyclopentadecanone and pentadecanolide and methods of using such mixtures are described. These mixtures possess substantivity to proteinaceous and cellulosic substrates which is significantly better than the substantivity of the separate components and are therefore very suitable for perfumes to be applied in products intended for treating skin, hair or textile fibers, such as bath and shower products, shampoos, laundry detergents, rinse conditioners, fabric softeners and the like. The mixtures are thus able to replace polycyclic musk fragrances in such products.

Abstract: A method of lining a side face (11) of a landfill site comprising the steps of erecting a framework (10) including laterally spaced substantially vertically extending members (12) adjacent the surface of the side face (11), covering the framework (10) with a wire mesh (15), filling the space between the mesh (15) and the side face (11) with pieces of substantially inert material (16), laying an impermeable liner (17) over the wire mesh (15) and constructing a retaining wall (20) over the liner (9), wherein the vertically extending members (12) are tubular and have spaced apertures thereto along their lengths.

Abstract: A liquid delivery nozzle having a circular dispersion plate having an upwardly facing concave side spaced from an output end or orifice of a tube connected to a water supply which may deliver water to the output end at a pressure in the range of 0.3 to 0.5 bars. The water issuing from the output end impacts on the concave side and spreads thereover to fly off the periphery of the plate in the form of drops having little or no vertical velocity component. The major part of the water issuing from the tube is converted into large drops of at least 0.7 mm in diameter. The nozzle can be used in an installation to prevent, suppress or impede the occurrence or development of explosions.

Abstract: A substrate (e.g. skin of unknown type, fabric, or hard surfaces) is characterized by analyzing chemicals emanating from the substrate or from a substance (e.g. a test formulation comprising a mixture of volatile chemicals) applied to the substrate. Analysis is preferably done using a volatile chemicals sensor, desirably a sensor comprising an array of conducting polymer sensors. The chemical analysis data obtained in this way may be statistically analyzed, e.g. by Euclidian distance mapping or principal component analysis, for ease of handling. Having characterized a surface in this way, products, e.g. cosmetic and cleaning products, may be formulated for optimized performance on that substrate.

Abstract: Apparatus for processing tissue samples for histological examination comprises a cassette defining a chamber to receive a tissue specimen and having an opening to allow processing fluids to enter and leave the chamber and to allow, eventually, molten wax to enter the chamber for embedding the tissue sample. The apparatus incorporates a temperature-sensitive valve mechanism for closing said opening once the cassette, with the tissue specimen therein, has been immersed in a container of hot molten wax, so that the wax can be retained in the cassette, around the specimen, when the cassette is withdrawn from the molten wax container, until the wax around the specimen has solidified. The temperature sensitive valve mechanism may comprise a shape-memory element.

Abstract: A graphics management system resident in a computer operating system provides a generic graphics interface which allows application programs written to operate with various specific graphical user interfaces, to operate on a non-native graphical user interface. The graphics management system includes a common graphical user interface (GUI) which receives graphics related application programming interface (API) calls from the application programs, and transforms the various types of graphics API calls native to a particular GUI, into a generic format compatible with a personality neutral graphics engine. The personality neutral calls are then passed from the CGUI to the personality neutral graphics engine which services the calls, and controls the drawing of lines, circles and other drawing tasks for each of the windows presented on the display. The present invention allows users to "port" application programs written for one GUI, to a computer system operating a different GUI.

Abstract: In a computer system having a cpu, a device for dynamic cpu clock adjustment. The device is comprised of a clock pulse generator for generating a clock frequency. The clock frequency is coupled to the cpu and is used by the cpu to synchronize and pace its internal operations. The clock frequency generated by the generator is variable over a range. A controller is coupled to the clock pulse generator, for adjusting the clock frequency from the clock pulse generator over the range. The controller interfaces with the computer system through an interface coupled to the controller. Through the interface, the controller communicates with the computer system or cpu and determines a load placed on the cpu. The controller adjusts the clock frequency generated by the clock pulse generator such that the clock frequency increases when the load on the cpu increases and the clock frequency decreases when the load on the cpu decreases, dynamically adjusting the clock frequency in response to the load on the cpu.

The present invention allows user to "port" application programs written for one GUI, to a computer system operating a different GUI.
