Patent CA-2165704-A1 (CA)
Inventor: ENSOR MYRA L
IPC: H04M1/715
Filed: 1995-12-20
Abstract: A telephone message system overcomes the problems and limitations of presently available systems that seek to enhance inter-and intra-premises communications. The system advantageously comprises a controller unit with Caller ID capabilities and one or more adjunct units that are bridged onto a single wire-pair at a user' s residential location in a parallel electrical connection. These customer installable units are merely plugged into any telephone jack and share a telephone wire-pair with existing telephone extensions without interference. Such operation is possible since communication between the controller unit and the adjunct units is limited to a frequency band different from the audio frequency band used by the existing telephone extensions on the single wire-pair. The controller unit, in one configuration, operates as an answering machine with multiple mailboxes. This functionality is advantageously combined with Caller ID, intercom and speakerphone capabilities. The adjunct units may be added to any of existing telephone devices thereby providing access to the functions available at the controller unit throughout the premises.

Title: Collated drywall screws
Inventor: HABERMEHL G LYLE
IPC: F16B23/00
Filed: 1996-08-07
Abstract: Collated drywall screws are provided for securing drywall to framing members. A collated screw has screws connected to each other by a holding strip. Each screw is received in a fragible sleeve about its threaded shank such that a screw on being screwed into a workplace is separated from the strip by the head of the screw passing through the sleeve breaking the sleeve. The improvement arises in having the head of the screw spaced from the fragible strip by a distance greater than the thickness of the drywall such that a screw is screwed through the drywall in at least partially into the frame support prior to the head of the screw engaging the frangible strip. The increased engagement with the frame member prevents the screw from stripping in the drywall and drawing drywall powder which may clog the power driver after repeated use. The invention provides drywall screws and a method of driving them which reduces the forces a use must manually apply to a power driver.

Title: Movable surface treatment device
Inventor: DUMMERMUTH PAUL
IPC: B28D1/18
Filed: 1996-09-11
Abstract: A motor is disposed above the protective covering or chassis of a movable surface treatment device. Via its vertically arranged power take-off shaft, the motor drives the horizontally extending rotor shafts, on which respectively one rotor cage is disposed on both sides of a gear housing. The rotor shafts are driven in opposite directions, so that one drum mills in the same direction and the other drum mills with opposite horizontal rotary movement. The gear housing is driven in a stepped-down manner via a two-stage transmission by a power take-off pulley disposed on the power take-off shaft. The rotor cages make two superimposed rotary movements. Thus, the treated surface no longer has a grooved appearance, the surface is treated more evenly and better, and finally, no self-driving force acts on the movable surface treatment device. Work safety is thus increased in addition to work quality One rotor cage is driven in the same direction, the other in the opposite direction with respect to the horizontal rotation, by which the work output is increased and the appearance of shadows is removed.

Title: Ultraviolet excited fusible ribs for plastic zipper profiles
Inventor: VAN ERDEN DONALD
IPC: B65D33/25
Filed: 1996-10-30
Abstract: A reclosable bag is formed of a first wall and a second wall of a polymeric sheet material joined to form an enclosure with a mouth defined by the wall edges.  The bag has a closure for selectively opening and sealing the mouth.  The closure includes a first and a second mutually interlocking profile, each of which extends along and is bonded to the internal surface of its respective first and second wall.  The first and second mutually interlocking profiles are extruded from a first polymeric resin material, and have a web portion which is bonded to the wall. Coextruded onto the web portions, or applied to the web portions following the extrusion of the strips, is at least one rib of a second polymeric resin material which includes an ultraviolet-light-excitable tracer material.  The second polymeric resin material has a lower melting point than the first polymeric resin material,  and is used to bond the profiles to the sheet material of the walls.  Before such bonding, the ribs appear as discrete lines under ultraviolet light. After a complete bonding, the ribs disappear and are replaced  by  a  smeared brightening  of  the  region between the profiles and the sheet material of the walls.  The appearance of ribs after bonding indicates an unsuccessful bonding operation that could possibly lead to an increase in the occurrence of leaking packages.

Title: Photocleavable agents and conjugates for the detection and isolation of biomolecules
Inventor: ROTHSCHILD KENNETH J
IPC: G01N33/532
Filed: 1995-05-11
Abstract: This invention relates to agents and conjugates that can be used to detect and isolate target components from complex mixtures such as nucleic acids from biological samples, cells from bodily fluids, and nascent proteins from translation reactions. Agents comprise a detectable moiety bound to a photoreactive moiety. Conjugates comprise agents coupled to substrates by covalent bounds which can be selectively cleaved with the administration of electromagnetic radiation. Targets substances labelled with detectable molecules can be easily identified and separated from a heterologous mixture of substances. Exposure of the conjugate to radiation releases the target in a functional form and completely unaltered. Using photocleavable molecular precursors as the conjugates, label can be incorporated into macromolecules, the nascent macromolecules isolated and the label completely removed. The invention also relates to targets isolated with these conjugates which may be useful as pharmaceutical agents or compositions that can be administered to humans and other mammals. Useful compositions include biological agents such as nucleic acids, proteins, lipids and cytokines. Conjugates can also be used to monitor the pathway and half-life of pharmaceutical compositions in vivo and in diagnostic, therapeutic and prophylactic purposes. The invention also relates to kits comprised of agents and conjugates that can be used for the detection of diseases, disorders and nearly any individual substance in a complex background of substances.
