Title: Colour highlighting manuscript indicia on a pre-printed form.
Inventor: CREGG MARTIN SWEENY
IPC: B42D5/04
Filed: 1994-11-11
Abstract: Selected areas 22, 26 of a pre-printed form are pre-prepared by application of a reactant so that, when written upon by a writing instrument containing a co-reactant, the indicia in said areas are in a different colour to indicia in other areas 20, 24 of the form written by the same instrument. In one embodiment, selected areas of the form are pre-treated with a bleach to which only one colour of a pen containing a mixture of colourants is sensitive, whereby untreated areas are marked by a mixture of colourants and treated areas exhibit only one of the colours. In another embodiment (Fig 10, not shown in abstract) the pen contains a colourformer which reacts to produce different colours with different co-reactants, and the form is differentially pre-treated (in areas 502, 504) with said co-reactants. In a variation of this embodiment, the pen also includes a colourant which marks untreated areas (505), whereby a greater variety of colours may be created by appropriate superimpositions of active colours. Described embodiments include calendars, telephone number and address books, planners, record keeping books, diaries, registers, and notepads of the kind having repositionable adhesive on the rear faces of the leaves. <IMAGE>

Title: Method of dissolving organic filter cake obtained in drilling and completion of oil and gas wells
Inventor: TJON-JOE-PIN ROBERT M
IPC: C09K8/512
Filed: 1993-07-01
Abstract: The invention shows a method of degrading damaging material within a subterranean formation of a well bore using an enzyme treatment. Filter cakes and very viscous fluids are such damaging materials. The enzyme treatment degrades polysaccharide-containing filter cakes and damaging fluids which reduces their viscosity. The degraded filter cake and damaging fluid can then be removed from the formation back to the well surface. The particular enzymes utilized are specific to a particular type of polysaccharide and are active at low to moderate temperatures. The enzymes attack only specific linkages in filter cakes and damaging fluids and are active in the pH range of about 2.0 to 10.0.

Title: Vibration-generating-motor mounting structure
Inventor: TAMARU TOSHIYUKI
IPC: H04W88/00
Filed: 1995-08-08
Abstract: A mounting structure of the vibration-generating-motor comprises a vibration-generating-motor and a holder for holding the vibration-generating-motor. A holding section of the holder contacts faced inner surfaces of a case and is held by the inner surfaces. Vibrations of the vibration-generating-motor are directly conveyed to the case through the holding section. For assembling, the holder holding the motor passes through a circuit board and is fixed by a hole formed on the circuit board. Then, the both ends of the holder are brought into contact with faced inner surfaces of the case so that the holder is held by the inner surfaces. The above structure enables vibrations of a vibration-generating-motor to be efficiently conveyed to the surface of the case and reduces undesirable sounds due to resonance of a circuit board. <IMAGE>

Title: Downhole sampling tool and method
Inventor: JONES TIMOTHY GARETH JOHN
IPC: E21B49/10
Filed: 1998-12-03
Abstract: The invention is to allow accurate determination of a predetermined volatile gas, e.g. H<SB>2</SB>S, in a wellbore fluid. The device comprises a hollow body having an interior sampling column 16 and an exterior sample probe (36, fig 1). The fluids enter the device, are guided through conduit 22 and can pass through valve 60 to the sample column 16. Sample column 16 has inlet valve 60 and inlet filter 54 which pass into the gas extraction system 64. The gas extraction system 64 uses a binding material in the form of spherical particles to cause the volatiles to react irreversibly to produce inert or non-volatile compounds, e.g. H<SB>2</SB>S to FeS<SB>2</SB>. The binding material depends upon the predetermined gas to be measured and can be transition metals or metal oxides, either of which can be doped, organic materials such as amines, or materials of the form R<SB>1</SB>R<SB>2</SB>XYR<SB>3</SB>R<SB>4</SB> where X and Y are carbon or nitrogen atoms and any of the two R groups contain electronegative groups.
