Title: Process for producing polyacetals, their use and the polyacetals produced
Inventor: FUNHOFF ANGELIKA
IPC: C09K23/00
Filed: 1993-08-16
Abstract: A process  for preparing polyacetals by copolymerization of glyoxylic esters with other copolymerizable monomers in the presence of anionic or cationic polymerization initiators, with or without the introduction of stable end groups and with or without hydrolysis of the copolymerized units of glyoxylic ester present in the copolymer comprises using as monomers cyclic  formals  derived  from  diols,  homopolymers  of formaldehyde, trioxepane or mixtures thereof, although up to 50 % by weight of this group of monomers may be replaced by other customary copolymerizable monomers, and the poly(acetal-carboxylate)s thus obtainable are useful as  additives  in reduced-phosphate  and phosphate-free detergents and cleaners, as water treatment agents and as dispersants for finely divided substances.
Patent CA-2141169-A1 (CA)
Inventor: WHETSTONE WILLIAM F
IPC: A47B13/08
Filed: 1995-01-26
Abstract: An edge molding is shaped to mount on a corestock in a cooperative relationship with a substantially flat surface top to form a two piece surface top assembly which is easy to install yet appears to be seamless. The edge molding has a facing wall, an integral first ledge and an integral second ledge, each extending at substantially right angles from the facing wall. An inside face of the facing wall has at least one longitudinally running excess adhesive flow-out groove and the inside faces of the ledges have longitudinally running gripper ridges. The second ledge preferably also has a drip channel on its outside face to interrupt the flow of spilled liquid.

Patent CA-2142854-A1 (CA)
Inventor: BOHMER WILLIAM
IPC: G01R31/36
Filed: 1993-08-17
Abstract: 2142854 9405053 PCTABS00030 A battery charge indicator is disclosed which is permanently incorporated into a battery to indicate the state of charge. The indicator includes a compressible chamber such as a blister (91) which is adapted to be installed in a battery (90) as an assembly.  The blister chamber is filled with a viscous gel and is exposed to the expandable cathode of the battery. As the battery discharges, the cathode expands thus causing the gel within the chamber to be extruded out through an outlet into a viewing channel in an overlaying disk (95). The amount of expansion of the cathode thus indicates the amount of discharge and, conversely, the remaining life of the battery. A battery charge indicator is also disclosed in which the expansion of the cathode is adapted to apply localized pressure to a disk. The localized pressure applied to the disk causes stretching of the material of the disk, which causes a visual indication of the state of charge of the battery.

Patent CA-2149141-A1 (CA)
Inventor: ONTAWAR SUSAN P
IPC: B41J2/175
Filed: 1993-11-12
Abstract: A non-refillable ink jet cartridge is rendered user refillable in a convenient manner. Hewlett-Packard ink jet cartridge #51626A is modified by sealing the vent hole at the base of the cartridge with a pressure sensitive adhesive tape, and removing the air tight ink fill plug at the top of the cartridge. After refilling with ink, a bellows type inflator bottle is used to inflate bladders within the cartridge making use of an opening in the cartridge. The ink fill opening is re-sealed either immediately before or just after the bladders are inflated, and the inflator bottle is then removed which releases the air pressure in the bladders causing the bladders to deflate. The deflated bladders cause an area of reduced air pressure to develop over the ink fill level, which prevents the ink from leaking out of the cartridge when the pressure sensitive adhesive tape covering the vent hole at the base of the cartridge is removed.

Title: Multimeter-like user interface for a graphical instrument
Inventor: BOYER KIM R
IPC: G01R1/04
Filed: 1995-07-12
Abstract: An interactive user interface for a graphical instrument allows the user to perform both multimeter-like functions and graphical functions simply and easily. Conventional "meter" test leads and receptacles couple measurement circuitry in the instrument to the signal being measured. A rotary switch is operable to select a measurement function while a keypad having "hard" and "soft" keys, is used to select operating modes. The hard keys are used to select a first operating mode that is independent of the selected measurement function and the soft keys are used to select a second operating mode that is dependent on the selected first operating mode. One hard key allows the user to select either numerical information about the parameter beingmeasured or graphical information about the measurement. A display includes a graphics portion that presents information related to the selected measurement function and first operating mode. Menus are presented in another portion of the display that provide information related to the second operating modes. The receptacles, rotary switch, hard and soft keys, display and related information are presented to the user on a single plane for contemporaneous viewing.
