Patent GB-2240337-A (GB)
Title: Aerosol carriers
Inventor: GANDERTON DAVID
IPC: A61K47/26
Filed: 1991-01-24
Abstract: Pharmaceutical excipients useful in dry powder inhalents comprise particles having a rugosity (measured by air permeametry) of less than 1.75. The use of these carriers increases the amount of drug injested by the patient using a dry powder inhaler. The preferred excipients are crystalline sugars such as lactose which may conveniently be prepared by controlled crystallisation from an aqueous medium.
Patent GB-2245766-A (GB)
Title: Interleaved helix antenna arrays
Inventor: PRABA KRISHNA
IPC: H01Q11/08
Filed: 1991-04-24
Abstract: Arrays (12, 14), of helical antennas (16, 18), operate at spaced-apart frequencies. In order to reduce mutual coupling between the antenna elements (16) of the lower-frequency array (12), they are spaced apart by a gap equal to or greater than one wavelength. The lengths of the lower-frequency helices are adjusted to move nulls in their radiation patterns into congruence with unwanted peaks in the array pattern, thereby suppressing the grating lobes. In order to reduce the total area of the arrays (12 and 14), the arrays are interleaved with each other. The higher-frequency array (14) has its antenna elements (18) spaced apart by a larger number of wavelengths than that of the lower-frequency array (12), so reducing the mutual coupling even further. The number of turns of the helices of the high-frequency array (14) are adjusted to bring nulls in the radiation pattern of the individual antennae (18) into coincidence with unwanted grating lobes. <IMAGE>

Title: Hot water generating and supply apparatus
Inventor: GRIFFITHS RICHARD MARTYN
IPC: F24H9/20
Filed: 1991-10-17
Abstract: In a thermal storage type of waterheater, the primary hot water (2) is heated to a lower temperature of about 65 DEG C by a first electric immersion heater (10) connected to a 24 hour cheap rate electricity supply and to a higher temperature of about 85 DEG C by a second electric immersion heater (11) connected to a cheap rate electricity supply available, as determined by a teleswitching device (17), only during selected time periods of the day/night.

Title: Scum-box in settling tank
Inventor: NICHOLLS PETER GEORGE
IPC: B01D21/24
Filed: 1992-04-21
Abstract: A scum-box (a) is mounted at the periphery of a settling tank by a bearing (c), which allows the front edge of the box to be pushed below the surface when a bar (f) carried by a rotating half-bridge, engages a roller (e). This causes any floating scum or rags, collected in front of a skimmer blade on the bridge or retained by a box-like structure thereon, to be sucked into the box and drained away via flexible hose (f). When bar (f) has passed, the box is restored to its raised position by a spring (d) and by the buoyancy of an enclosed volume (u). The box could be tilted by an actuator separate from the half-bridge. <IMAGE>
Patent GB-2265359-A (GB)
Title: Packing box having means for protecting the contents
Inventor: BOOTH RICHARD
IPC: B65D5/355
Filed: 1992-04-22
Abstract: A packing box made of a semi rigid material such as corrugated cardboard has integral packing flaps 1 and 2 that have slots 3 and tongues 4 and crease/bending lines 5 and 7. When these flaps are operated, before sealing of the top outer flap(s), they adapt and lock together to form a thin walled structure in the void that occurs between the upper surface of the goods, and outer top flap(s) of a partly filled box. This enables the goods to be protected from excessive movement and thus reduce the risk of damage during handling, transportation and storage. <IMAGE>

Title: Controlled driving of an electromagnetic load
Inventor: VELDTEN BURKHARD
IPC: F02D41/40
Filed: 1993-07-09
Abstract: A method of and drive means for controlled driving of an electromagnetic load (120), in particular an electromagnetic valve of a fuel injection system in an internal combustion engine, entails presetting the switching times of the valve, for the determination of the start and/or the end of injection, in dependence on an engine operating parameter, especially engine speed. The drive means comprises a first switch (110) and a second switch (165) respectively in series and in parallel with the valve (120) and respectively associated with a rapid-quenching diode (150) and a freewheel diode (160). The second switch (165) is so selectively driven by an electronic control unit (100) in dependence on engine speed range that current decay through the valve on switch off by the first switch (110) is influenced by the diodes in a manner varying the valve switching time according to the speed range, whereby a compromise can be achieved between desired short switching times and desired low noise generation. <IMAGE>

Production can take place at variable flow rates and can meet changing demands for nitrogen of different purities. The column is kept cold by the injection of the medium purity liquid nitrogen. Cooled air is fed to the column through pipe 14, the air having been previously purified in apparatus 2 and passed through heat exchanger 3. Liquid air enriched with oxygen is sent to condenser 10 via pipe 15 fitted with expansion valve 16, vapourized enriched air leaving condenser 10 via pipe 29. The column may be modified to produce nitrogen of more than two different purities and may be used in connection with the electronics industry. <IMAGE>
