Patent number: 6887571Abstract: Silicon carbide particles coated with a pigmented coating result in silicon carbide particles which can be used in slip resistant flooring to achieve the desired slip resistance whilst giving improved aesthetic properties. The pigmented coating can be an organic coating such as a two part epoxy system or a water based or solvent based epoxy. Alternatively the pigmented coating can be an inorganic coating such as a ceramic glaze. Also provided are methods of coating silicon carbide particles with either an organic or an inorganic pigmented coating. Further provided are safety flooring materials including silicon carbide particles having a pigmented coating.Type: GrantFiled: March 30, 2001Date of Patent: May 3, 2005Assignee: Altro, LimitedInventor: Adrian John Shortland

Patent number: 6579610Abstract: A flooring material (1) comprises a base portion (2) having a coating portion (3) which imparts improved stain resistance to the flooring material (1) and is positioned in contact with an upper surface of the base portion (2). The coating portion (3) creates an upper surface of the flooring material (1). A particulate material (6) is embedded in the coating material (3) and at least partially penetrates the base portion (2). The particulate material (6) provides a roughened effect to the upper surface of the flooring material (1) and protects the coating from wear. The coating (3) merges into the base portion (2) where they meet at joint (4) to form a stratified portion (5).Type: GrantFiled: June 1, 2001Date of Patent: June 17, 2003Assignee: Altro LimitedInventors: Adrian John Shortland, Karen Alexandra Masters

Patent number: 6304874Abstract: In a brokering system for items of software or data, submission inputs are made to a database. Each submission input includes a descriptive data set in relation to a unit of data or software, together with an address field. The brokering system loads the submission input to the database and copies it to temporary stores identified in the address field. Each temporary data store is allocated to a respective index management interface and is viewable to that index management interface only. Inputs can be made at the index management interface to transfer the descriptive data sets received to an index accessible by a plurality of search interfaces, or simply to delete the descriptive data set from the temporary data store.Type: GrantFiled: June 26, 1998Date of Patent: October 16, 2001Assignee: British Telecommunications public limited companyInventors: Stephen Leslie Corley, Edward John Percival Hayes, Jonathan William Reed, Richard John Shortland, Benjamin Roy Whittle

Patent number: 4958510Abstract: Fastener installation apparatus, for installing fasteners such as blind rivets of the type which includes a washer-like member (13) which is free to fall away from the installed fastener, is provided with temporary retaining means for temporarily retaining the washer-like member on the installation apparatus after installation of the fastener. The temporary retaining means comprises a pair of gripping faces (42, 42) which project forwardly from the reaction faces (25, 25) of a pair of members (40 or 48) which are part of the nosepiece of the apparatus. The gripping faces (42, 42) close together automatically to grip the washer-like member as the installation apparatus installs a fastener, and draw apart again to release the washer-like member as the installation apparatus returns to be ready to receive a further fastener for installation.Type: GrantFiled: July 26, 1989Date of Patent: September 25, 1990Assignee: Avdel Systems LimitedInventors: Keith Denham, Donald S. Savage, John A. Shortland
