Title: Extracting halocarbons
Inventor: CARR ROBERT JEFFREY GEDDES
IPC: C10G21/00
Filed: 1997-03-25
Abstract: A solvent extraction process for extraction of halocarbon contaminants, particularly polychlorinated biphenyls (PCBs), from hydrophobic materials, especially hydrophobic liquids and solids such as oils and fats, comprises contacting an oleophobic perfluorocarbon (PFC) fluid, in which the halocarbon contaminant is at least partially soluble, with the contaminated liquid or solid by means of a recycling liquid-liquid or solid-liquid continuous extraction apparatus 10 where the PFC fluid is contacted with the hydrophobic material, the contaminants are at least partially extracted into the PFC fluid, the fluid is removed from the hydrophobic material into a separate PFC boiling zone 23 where the fluid is converted to a vapour leaving the higher boiling point contaminants remaining in the PFC boiling zone. The contaminant-free PFC vapour is passed to a condenser 30 in which the PFC vapour is condensed into a liquid and reintroduced into contact with the hydrophobic material 5.

Title: Thermoelectric cooler for semiconductor devices
Inventor: ROWE DAVID MICHAEL
IPC: H01L23/38
Filed: 1997-08-21
Abstract: A one-piece semiconductor assembly comprises a thermoelectric cooling device 14 and a semiconductor device (not shown) formed on a first region 17 of the cooling device 14. The thermoelectric cooling device comprises a substrate 10, a series of alternate n-type and p-type semiconductor elements 15,16 overlying the substrate 10 and extending between the first region 17 and a second region 18, the elements 15,16 being interconnected such that heat is transferred from the first region 17 to the second region 18 over a diaphragm in the substrate 10, when current flows through the interconnected elements 15,16. The semiconductor device is thus cooled by the thermoelectric cooling device 14 and the void 12 in the substrate 10 creates a thermal barrier which helps to prevent heat from being conducted back from the second region 18 to the first region 17 through the substrate 10.

Title: Method and apparatus for delivering aggregate.
Inventor: KUJAWA ANTHONY
IPC: E01C19/08
Filed: 1997-09-29
Abstract: A method for delivering aggregate e.g. bituminous road stone comprises the steps of filling a container 8 with aggregate, transporting the container by transport vehicle 2 to a distribution site, demounting the container from the vehicle, loading customer vehicles from the container then remounting it on a transport vehicle and returning it. The remounting and returning is preferably carried out when the container is either empty, the temperature of its contents has fallen below a preset value or a preset time interval has elapsed since the container was last filled. The container is provided with a screw conveyor 22 at its base for conveying its contents out of an outlet 26. It also has a retractable support 29 which, when the vehicle is demounted, is extended to support the outlet above the ground, in particular above the level of a customer's vehicle so that material may be ejected from the container directly into the vehicle. The container may be constructed with a double wall to provide insulation, the gap between the walls being filled with rock wool and/or the container may be heated. A hook lift assembly 6, 30 may be used for demounting and remounting the container. Further features include wheels or rollers 21, 23, a lid 10 preferably lockable and a power supply 24 to drive the screw conveyor.

Title: Automatic gas powered valve
Inventor: HOBBS MARK ALISTAIR
IPC: F16K17/40
Filed: 1998-03-07
Abstract: A sender unit comprises a body Y having at one end a CO2 cylinder A with a soft sealed exit B, and at the opposite end a chamber F containing sodium (or a material with similar properties) E. When sufficient heat is applied the sodium will expand and push spear D up cylinder Z such that hardened point C will penetrate the CO2 cylinder to release gas via the soft sealed head B. The escaping gas moves along small bore tubing G to reach a valve (see figures 2 and 3). The gas forces piston (C+S) down liner body (L) until it stops flow of fluid at V. A detent, comprising an O-ring R and indent O, prevents the piston being forced back by fluid pressure W+V. The valve has a union (N), a body (T) and a thread (U).
