Abstract: ABSTRACT OF THE DISCLOSURE An apparatus (10) for applying thin film polymer labels onto small cylindrical articles has a label transport drum (20) with a substantially smooth, outer surface on which labels are fed.  A cold adhesive that is viscous at room temperature is printed onto an area adjacent the leading edge of the label.  A solvent is applied by two static wiper assemblies (172a, 172b) onto an area adjacent the trailing edge of the label.  The first static wiper assembly (172a) wipes an amount of solvent onto the area adjacent the trailing edge of the label for cleaning and softening that area.  A second wiper assembly (172b) applies an amount of solvent onto the area adjacent the trailing edge of the label for dissolving a portion of the label to create a tacky, bonding quality to the label and form a solvent seal bond when the trailing edge overlaps the leading edge.  Solvent is applied to the wiper bodies (172a) for dispersion throughout and to the wiper tip.  A plunger (132) is formed in the drum at those areas where the trailing edges of labels are positioned.  Each plunger (132) is spring biased outward from the drum surface to position the trailing edge of a label at a position beyond the peripheral drum surface for engaging the wiper tips. During wrapping, the article forces the plunger downward so it will not interfere with article wrapping.

Patent CA-2105851-A1 (CA)
Title: Dressing of blow-molded articles in a strand
Inventor: FANG JIN-LIOU
IPC: B29C49/72
Filed: 1993-09-09
Abstract: A dresser apparatus is provided for a strand of blow-molded articles interconnected by shorter flashings. A first pair of first rollers and a second pair of second rollers are of the gear type and are mounted for rotation to define pinching planes therebetween along which the strand is directed. The second rollers are relatively spaced to engage the articles and flashings passing therebetween, and are spaced from the first rollers such that the second rollers engage each flashing or article while a succeeding article or flashing is being engaged by the first rollers. A second moving device rotates the second rollers at a predetermined speed which is greater than the speed of the first rollers. Thus, each flashing or article is pulled from the succeeding article or flashing. A final pair of final rollers is mounted for rotation and defines a final pinching plane rotated (turned) with respect to the second pinching plane so that deformation of the articles caused by engagement with the first and second rollers is compensated for by passage through the final rollers. The dresser apparatus may include a third pair of third rollers spaced from the second rollers by a distance longer than the flashings but shorter than the articles so that the separated flashings fall between the second and third rollers while the articles are passed from the second to the third rollers:

Patent CA-2114129-A1 (CA)
Title: Aerofoil with variable geometry expansion surface
Inventor: ASHILL PATRICK R
IPC: B64C3/48
Filed: 1992-07-28
Abstract: A wing, or similar article of aerofoil section, has a variable geomety surface for the active control of shock strength and transonic wave drag. In one embodiment, the wing has a region of distensible skin (4) aft of the line of maximum section, which extends along the span of the wing in those areas that experience drag.  Pressure means (10, 20, 30) within the wing outwardly def-lest the distensible region and produce a local bulge in the expansion surface. This bulge induces pre-shock compression and re-duces the effect of the shock. The bulge is retracted by the natural elasticity of the skin material (which can be a conventional alu-minium alloy) upon removal of the applied pressure. In another embodiment, the wing has a ramp portion (14) which is outwardly deflectable for the same purpose, The invention is applicable to supercritical and natural laminar flow wings.

Patent CA-2118879-A1 (CA)
Title: Low-Delay Stubband Adaptive Filter
Inventor: MORGAN DENNIS R
IPC: G06F17/14
Filed: 1994-03-11
Abstract: A subband adaptive filter is disclosed that retains the computational and convergence speed advantages of subband processing while eliminating delay in the signal path. The technique has applications in active noise control where delay seriously limits cancellation performance and in acoustic echo cancellation where transmission delay specifications may limit the use of conventional subband designs. A reference signal and a residual error signal are each decomposed into a plurality of subband signals, and a set of adaptive weighting coefficients is generated for each of these subbands by a conventional complex LMS (least-means-squared) technique. These sets of subband weighting coefficients are then transformed into the frequency domain, appropriately stacked and inverse transformed back into the time domain to obtain wideband filter coefficients for a programmable filter. The reference signal, which is correlated with the disturbance signal to be eliminated, is filtered by this programmable filter to produce a disturbance estimate signal which may be subtracted from the signal containing the disturbance.  The process iterates in order to minimize the residual error signal and thereby reduce the disturbance.
