Title: Foamable formulation and foam
Inventor: TRAINER EILIDH
IPC: A61K47/08
Filed: 1999-10-07
Abstract: There is described a formulation comprising a foamable gelling agent (such as alginate, carageenan or carboxymethylcellulose gels) and a slow-release precipitant therefor. The precipitant is combined with the gelling agent during foaming and stabilises the foamed form of the gelling agent. Suitable precipitants include calcium salts such as calcium citrate and calcium chloride, or aluminium salts such as aluminium chloride. The increased stability of the foam facilitates sterilisation thereof. Further improvements can be obtained by exposing the cured foam to a precipitant applied externally, optionally washing, and then drying the foam. The foam of the present invention is suitable for medical or veterinary use and can include active ingredients for delivery to, for example, a wound site.

Title: Improvements relating to patient carrying platforms
Inventor: JAMES GAVIN HUGH
IPC: A61G7/10
Filed: 2001-02-28
Abstract: "Improvements relating to patient carrying platforms"      A moveable support platform incorporates a base plate 1 mounted on front castor wheels 2 and rear castor wheels 3.      Side struts 7 extend up from the base plate 1 and between these is mounted a gripping and pushing bar 8. At a central location of the base plate 1 a guide cover 11 supports the spindle of a larger wheel 12. A patient standing on the base plate 1 can support himself by gripping the bar 10 and can be moved around on the base plate 1 by a helper. When it is necessary to move the construction around a corner or to rotate into the reverse direction, pushing or pulling on the bar 8 will tend to rotate the whole support platform construction generally about the central wheel 12, with the various pulley wheels rotating around the axis of the wheel 12.

Patent CA-2349219-A1 (CA)
Inventor: BAUMER MICHAEL F
IPC: B41J2/175
Filed: 2001-05-29
Abstract: A method and apparatus is provided for separating the liquid and non-liquid components of a foamy mixture. The apparatus comprises a filter means through which the liquid portion of the foam can pass and through which the gaseous or air component cannot pass, unless a pressure differential across the filter exceeds the bubble point of the filter. First means are provided to supply the foam to a first side of the filter means.      Additional means are provided to remove the liquid component of the foam from the second side of the filter, and the gaseous component of the foam from the first side of the filter. A pressure differential is established between the two sides of the filter to cause the liquid component of the foam to pass through the filter; but the pressure differential across the filter is prevented from exceeding the bubble point of the filter to prevent the gaseous component of the foam from passing through the filter.
Patent CA-2350332-A1 (CA)
Inventor: KANG DAE WOO
IPC: F42D1/00
Filed: 2000-02-16
Abstract: A rock blasting method is provided in which a series of aligned boreholes are charged with explosives and air tubes in a predetermined pattern. The air tube is a cylindrical flexible tube having a predetermined width and length to be fitted with the borehole. In one preferred form, each borehole is charged with the explosives and detonator with one air tube installed above the explosives. A stemming material is installed above the air tube. For example, in a 45-millimeter diameter and 2.5 meter long borehole, the length of explosive charging is 0.8 meters, the co-operating charge weight was 0.648 Kg, the total amount of explosives 3.24 Kg, the length of the air tube 1.0 meter, the diameter of air tube 40 millimeters, and the length of stemming 0.7 meters. The explosives and air tube may be alternately charged along the borehole. The use of air tubes, charged above at least one explosive layer allows a quantitative air decking in every blasthole. A reduction in detonation velocity and noise is observed in the field test. Also, the air-deck effect can be easily obtained: an increase in fragmentation rate with minimizing the production of boulders. A reduction in explosive usage is also achieved.
