Patent GB-2204382-A (GB)
Title: Fluid pressure valve
Inventor: HEDDERICK JOHN BARCLAY
IPC: B67D1/12
Filed: 1987-05-01
Abstract: A fluid pressure control valve and a fluid control system (such as for beverage dispensing) with such a valve has a beverage passage (3), pressure fluctuations in which are detected by a diaphragm (17) to displace a sensing member (15) axially against spring loading (23). Spring (23) reacts on thrust member (22) which is adjustable axially through a cam mechanism (25/26) to vary the biasing force of spring (23). A valve member (20) spring loaded at (21) relative to thrust member (15) normally closes an exhaust port (19) to an air or other gas passage (5) through which gas passes under pressure to be injected into the beverage from passage (3). An increase in beverage pressure in passage (3) displaces sensing member (15) to increase the spring biasing (21) on the closure member (20) and reduce the proportion of air which can escape to atmosphere from passage (5) through exhaust port (19) to provide an increase in air flow into the beverage. A reduction of pressure in passage (3) reduces the spring biasing (21) to permit a greater proportion of air to escape from passage (5) through exhaust port (9) and thereby reduce the proportion of air which is introduced into the beverage. The control valve can include a temperature sensitive unit responsive to temperature of beverage in passage (3) and which reacts to adjust the force of biasing spring (21) independently of pressure in the passage (3). Plunger (51) can be depressed manually to close the exhaust port (19) temporarily and thereby maintain maximum air pressure in the passage (5).

Patent GB-2212445-A (GB)
Title: Data carriers
Inventor: DRINKWATER KENNETH JOHN
IPC: G06K19/16
Filed: 1988-11-16
Abstract: A carrier (1) bears data in the form of one or more optical microstructures (4/5) representing e.g. identification data on an access-control card or authentication data for documents or goods. Each microstructure comprises adjacent first (4) and second (5) elements of identical form, but arranged in a laterally inverted relationship, and located beneath a partially transparent and partially reflective surface (6) of the carrier. To read the data, light of a selected wavelength and incidence angle (7) is directed through the said surface (6) to the first optical element (4), which directs it through the structure of the carrier to the second optical element (5). The latter directs the light out of the carrier once more, in a direction (9) parallel to the direction (7') at which a proportion of the incident light is reflected at the surface (6) of the carrier, which makes it extremely difficult for an unauthorised person to discover the location and characteristics of the optical microstructure (4/5) by trial and error methods. In the proper reading apparatus for such carriers, a mirror (11) is correctly positioned close to the carrier surface to intercept the light emerging from the second optical element(s) (5) and so direct the same to an appropriate detector (12). The optical structures may be solid holograms (Figs 1-3) diffractive structures (Fig 4) or reflectors (Fig 5); and the optical path therebetween may be direct (Fig 1) or may involve internal reflections from a surface of the carrier (Figs 2-5). <IMAGE>

Title: Energy management system
Inventor: COOPER TIMOTHY PATRICK
IPC: G05D23/19
Filed: 1988-11-25
Abstract: The system includes a control computer which transmits control signals to a number of outstation control units, each associated with a particular location in a building or building complex. The control computer receives information such as external temperatures (from both north- and south-facing walls), maximum electrical demand information, weather forecast data and thermodynamic models of buildings. In addition to this, each outstation control unit includes air temperature and occupancy detectors for its associated location and subsequently controls operation of energy consuming devices such as heating and lighting systems in response to information received. Energy consumption information is also used by the control computer to provide maintenance management information such as time scales for work to be done, costs which have been incurred etc.
