Patent CA-2060196-A1 (CA)
Title: Binder for absorbing oily liquids
Inventor: LEONE DEMETRIO
IPC: D04H1/544
Filed: 1991-04-29
Abstract: Wet polyolefin fibrils (10) of hydrophobic nature and cooled in water (24) are placed on a water-permeable tape (14) continuously circulating over at least two rollers (18, 20), where the water (24) drains off. The polyolefin fibrils are then guided to a heated roller (22) of large diameter. The fibres are dried to form a compact, tape-like nonwoven (28) on the surface (26) thereof, compressed and wound or cut into sections. The nonwoven is passed to a comminuting and disintegrating machine (32), in particular a hammer mill or a mixer, for impacting, after appropriate storage. A  loosened, flaked, hydrophobic pulp which has a large absorption capacity for oily liquids, for example crude oil or derivatives thereof, is thus produced. The flaked, hydrophobic pulp loosened by impacting has a greater absorption capacity than a nonwoven.  The polyolefin fibrils (10) of a binder are joined to one another at points by means of thermobonding.
Patent CA-2061044-A1 (CA)
Inventor: BARRY JAMES V
IPC: G01N35/00
Filed: 1992-02-11
Abstract: There is disclosed a method for automatically adjusting a dispensing tip from a surface onto which liquid is to be dispensed, a proper distance that precludes the dispensing stream from puddling up, or from breaking apart.  The method features the formation on the tip of a meniscus of a nominal small volume and advancing the tip and meniscus until the surface is contacted.  The resulting decrease in pressure in the tip is measured, to trigger the tip to stop its advance and to start dispensing.  In circumstances wherein the contacted surface is hydrophobic so as to ideally require a meniscus depth greater than the nominal depth, the tip is retreated from the surface, during dispensing, to the ideal depth.

Patent CA-2066930-A1 (CA)
Inventor: SACH GARY M
IPC: H01H13/703
Filed: 1992-04-23
Abstract: A tactile  feedback switch actuator  (12)  for an associated force-actuated switch (52) has a key cap (22) linked to a collapsible dome (34) by an optical fiber (36), all of which are light-transmittable.  The actuator (12) is operated by manually applying an actuating force to the key cap (22) which exceeds the modulus of collapse of the dome (34).  In response, the dome (34) reversibly collapses  in  a  tactile  snapping  action  against  the underlying light-transmittable switch panel (54) having pressure-sensitive contacts (62a, 62b) embedded therein to change the operative state of the switch (52).  When the actuating force is withdrawn, the collapsible dome (34) elastically returns to its uncollapsed condition, while the switch  (52)  remains  in  its newly-actuated operative state.  The actuator (12) and associated switch (52)  are structurally integrated and aligned so that light-emitting   pixels    (60)    in   an   underlying electroluminescent panel provide visual feedback of the operative state of the switch (52).

Title: Fully rotatable vacuum lift with self contained utility lines
Inventor: MESSINGER ROBERT
IPC: B66C13/14
Filed: 1992-06-08

Patent CA-2077532-A1 (CA)
Inventor: KOBLITZ RUDOLF
IPC: H03L7/10
Filed: 1991-04-19
Abstract: PLL control circuits in horizontal oscillators, when locked, must have a low control rate so that, for example, no jitter is generated by noisy input signals. Owing to the infavourable scanning ratio between the synchronising pulse length and the line duration (4.7:64), however, the control rate at greater phase differences in the PLL input signals is low and, e.g. when a television receiver is switched over between different programme sources, it takes a relatively long time (a few half-images) for the line synchronisation to become locked again. By logically assessing an additional pulse already available or easily generated in the television receiver, the control signal for the VCO in the PLL may be switched over at greater phase deviations, e.g. to a fourfold control current. For PLL control with input signals which do not have a pulse-duty factor ratio of 50:50.

Title: Image processing arrangement
Inventor: PENNA DAVID EDWARD
IPC: G06T3/40
Filed: 1992-12-17
Abstract: ABSTRACT                    IMAGE PROCESSING ARRANGEMENT     A microprocessor (MPU) is programmed to process pixel values of an input image to generate an output image, by means of systematic selection and combination of input pixel values.  The system for selection and combination depends on a variable parameter (for example a zoom factor).  Means responsive to the parameter value compiles (401) a machine code subroutine which is specific to that parameter and will cause the generation of one row of output pixel values.  This compiled filter is then executed repeatedly (408) to generate all rows of the output image.  The arrangement substantially eliminates per-pixel decisions, and is consequently faster than conventional microprocessor arrangements.      (Figure 4).

Title: Methode et dispositif pour mesurer les niveaux d'amplitude successifs de signaux recus sur une voie de transmission
Inventor: COQUEREL PATRICK
IPC: H04L25/06
Filed: 1992-12-18
Abstract: La mesure des niveaux successifs d'un signal reçu est effectuée en combinant entre eux les éléments de groupes d'échantillons numérisés qui sont prélevés sur le signal durant des fenêtres d'échantillonnage successives positionnées par une horloge locale maintenue bien synchrone avec le signal. La combinaison consiste en une moyenne pondérée de manière à tenir compte des conditions de transmission: bande passante de la voie, débit requis, bruit de fond etc, susceptibles de déformer les signaux transmis et donc d'entraîner des erreurs sur la mesure de leurs niveaux réels. Pour mener cette pondération à bien, on utilise les mots numériques d'un même groupe pour adresser une mémoire où l'on a rangé au préalable les valeurs qu'il convient de choisir pour chacun d'eux.. Application à la mesure de signaux codés à niveaux multiples par exemple.

Filed: 1993-05-27
Abstract: A base reinforcement fiber sheet of carbon fibers, in which the carbon fibers are arranged uni-directionally via an adhesive layer on a support sheet, is wound on the surface of a portion of a concrete electric pole to be repaired. Then, a reinforcement fiber sheet of insulating fibers, in which the insulating fibers are arranged uni-directionally via an adhesive layer on a support sheet, is wound as the outermost layer to fully cover the carbon fibers. Either before or after the winding of the carbon fibers and insulating fibers, the fibers are impregnated with a thermosetting resin, which is then cured to obtain a fiber reinforced composite material. In this way, electric poles can be readily repaired to restore the mechanical strength thereof, and it is possible to provide an electric pole, which can prevent occasional accidents and ensure daily safety.
