Patent CA-2096935-A1 (CA)
Title: Removable adhesive tape
Inventor: KRECKEL KARL W
IPC: C09J7/24
Filed: 1991-12-16
Abstract: The present invention relates to adhesive tapes, more particularly to tapes that can be firmly adhered to a substrate and can be removed without damaging the substrate. Adhesives formulated to provide a substantial level of adhesion, e.g., greater than 30 oz./in, adhesion to paper, are generally difficult to remove without damaging the substrate. Easily removable tapes of the prior art are highly elastic and exhibit large recoil when the stretching force is removed, in the same way a rubber band snaps back up-on removal of the stretching force: This recoil characteristic can be dangerous, and increases the force required to debond these tapes at low angles. Finally, these highly elastic tapes tend to substantially recover their original shape when the stretching force is removed, and they are therefore not useful for indication of tampering or for guaranteeing single uses for hygienic purposes. This invention provides removable adhesive tape comprising a highly extensible and substantially inelastic backing and a layer of pressure-sensitive adhesive. The backing has a high tensile strength, has a lengthwise elongation at break of at least about 150 % with less than about 50 % elastic recovery after stretching. The adhesive can be a normally tacky and pressure-sensitive adhesive and is coated on at leash one surface of the film backing. The adhesive is preferably highly extensible, does not separate from the backing during stretching, and has higher cohesion than adhesion to any suitable substrate. After being applied to a substrate, the adhesive tape of the present invention becomes firmly bonded, but can be easily removed without damaging the substrate by sim-ply stretching it in a direction substantially parallel, i.e., less than about 35°, to the surface of the substrate.

Patent CA-2111939-A1 (CA)
Inventor: HASEGAWA ATSUSHI
IPC: H04B3/03
Filed: 1993-12-20
Abstract: In a voice activity detector for an echo canceller, a difference is detected between a voltage at the receive path of a four-wire circuit of a hybrid transformer and a voltage at the transmit path of the four-wire circuit, the difference producing a first difference signal, and an echo return loss estimate is derived from the first difference signal. The first difference signal is compared with the loss estimate to produce a first binary signal. A difference is detected between the voltage at the transmit path and an output voltage of the echo canceller to produce a second difference signal, and an echo return loss enhancement estimate is derived from the second difference signal. The second difference signal is compared with the loss enhancement estimate to produce a second binary signal which, together with the first binary signal, forms one of a plurality of combinations of binary levels. An estimator of the echo canceller is enabled in response to apredetermined one of the combinations of binary levels, and is disabled in response to the other combinations.

Title: Biological screens for detection of herbicides
Inventor: BASCOMB NEWELL F
IPC: C12Q1/48
Filed: 1994-01-27
Abstract: This invention pertains to novel protocols for the screening and rapid identification of compounds that specifically inhibit a predetermined enzyme or metabolic target site or pathway that is specific to plants. Enzymes which are specifically or indirected affected by the novel screens include glutamine synthetase (GS), 3-deoxy-D-arabino-heptulosonate 7-phosphate synthase (DAHP), dihydrodipicolinate synthase (DHPS), acetohydroxyacid synthase (AHAS) and phosphoribosyl anthranilate transferase (PAT). The enzymatic pathways targeted by the novel screening protocols are unique to plants, bacteria and fungi and are present at low levels. Thus, inhibiting these enzymes should present little or no toxicity to humans or animals. The screens provide an efficient and rapid method for assessing the herbicidal potential of test compounds. Lead compounds identified by the novel screening protocols can be used as herbicides to inhibit growth.
