Patent CA-2041857-A1 (CA)
Inventor: UETRECHT DAVID S
IPC: B64G1/24

Abstract: ATTITUDE CONTROL SYSTEM FOR MOMENTUM-BIASED SPACECRAFT           ABSTRACT OF THE DISCLOSURE An attitude and nutation control system (30) for a momentum-biased vehicle (19) having roll, pitch, and yaw axes which employs a normal mode estimator  (32)  which predicts steady-state values for roll attitude, roll rate, and yaw rate.   The normal mode estimator (32) receives instantaneous roll attitude information from an earth sensor (34) and optionally receives roll and/or yaw rate information from roll gyro (35a) and yaw gyro (35b).  A logic circuit (36) coupled to the normal mode estimator (32) generates correction signals when the steady state values for roll attitude, roll rate,  and yaw rate are outside predetermined limits.  A plurality of thrusters (14a-d)  produce  torque  for bringing  the  steady-state values for roll attitude, roll rate, and yaw rate within predetermined limits.  A sample/hold-off control circuit (68)   samples   correction   signals  between  thruster activations while a optimal thruster selection logic (70) employs a linear program to compute torques associated with changes in the correction signals for use by the normal mode estimator (32), as well as activating selected thrusters (14a-d).

Abstract: The self-adhesive dry-transfer images of the invention have, applied on a coated paper substrate (ref No. 5 in Figs. 1-3), either two layers, viz: first one or more inks (ref. No. 3 in Fig. 1) and then an adhesive (ref. No. 2 in Fig. 1), or only one layer, viz: a coloured adhesive or an adhesive ink (ref No. 2 in Figs. 2 and 3). The layer(s) are preferably applied by a silk-screen process to sheets of size 140 x 100 cm, at a speed of at least 400-2,000 or 7,200 sheets per hour, each layer coinciding with the image represented by the ink(s). The adhesive is covered by a coated protective paper sheet (ref. No. 1 in Figs. 1 and 2) which adheres easily to the adhesive without the need for other means, but which can be detached again completely from the layered structure (ref. Nos. 2-5 in Figs. 1 and 2) by pulling (ref. No. 7 in Figs. 1 and 2), without pulling the layered structure from the substrate paper (5). In Fig. 3, the back of the substrate paper is also coated for additional protection. The self-adhesive dry-transfer images can be applied to, for instance, a shopwindow (ref. No. 6 in Figs. 1-3) or some other support material, which may have a textile or rounded surface, by pulling off the protective paper sheet (ref. Nos. 7 and 1 in Figs 1 and 2) covering the adhesive, placing the dry-transfer image against the support material, rubbing with light pressure (ref. Nos. 8 in Figs. 1-3) and finally pulling off the sheet of substrate paper (ref. Nos. 9 and 5). The self-adhesive dry-transfer images can normally be removed again easily and without trace from a smooth pane of glass by scraping off with a scraper blade. Any adhesive remaining can be wiped off with water.

Title: Method for operating a circuit arrangement for a sanitary fitting
Inventor: KUNKEL HORST
IPC: G01S17/04
Filed: 1991-06-18
Abstract: A circuit arrangement for a sanitary fitting controlled in a non-contacting manner comprises a transmitter (3) as well as a receiver (4), at which radiation emitted by the transmitter (3) arrives after reflection on an abject (7). In an initialisation process, which takes place for the first time after the initial installation, thereafter at greater regular time intervals, the capacity of the transmitter (3) is increased until the reflection on a stationary object (7) in the monitoring range has the result that the evaluation circuit (5) following the receiver (4) is activated. Now the capacity of the transmitter (3) is once more reduced somewhat; the circuit arrangement changes to normal operation. It now has its optimum sensitivity, at which stationary objects (7) no longer cause faulty actuations, but the greatest possible monitoring range is provided for movable objects to be monitored.

Title: Gilbert's paint tray saver
Inventor: HUNEAULT GILBERT
IPC: B44D3/04
Filed: 1991-07-26
Abstract: ABSTRACT      In a tool for holding paint, it is known to be constructed of metal or plastic and contoured into a form that possesses both a shallow end and a deeper end in which paint is held and disposed of.  Subsequently the paint roller is positioned in the deep end of the tray and rolled towards the shallow end to disperse the paint more or less evenly on the roller.  Use of such a tray would unfortunately necessitate the unpleasant task of cleaning it after each use with harmful solvents.  This is necessary so that the tray is clean for future use or to apply paint of a different colour. The solvents are potentially harmful  to both the user and the environment.    This particular  invention  relates  to  a  new improvement  in  the painting  field,  and more  particularily  to improvements in paint trays used in connection with the application of paint to a paint roller, as earlier described.  The tool would be constructed of a flexible, form-fitting, paint-impervious wrap or latex plastic which would be placed into the interior of the paint tray.   It would be firmly held within by means of self-adhesive material on the bottom of the wrap and by an elasticized band fitted onto the perimeter of the wrap and placed snugly over and under the tray's outer lip, thus abolishing actual contact of the paint to the tray.  One objective of this tool is to provide a paint tray liner within the tray when in use, and which is also adapted to be readily detached and disposed of when the task is completed.     .../2

Inventor: LEWIS LEO A
IPC: H04R1/28
Filed: 1991-08-12
Abstract: This invention relates generally to vented loudspeakers for the reproduction of musical sounds, but particularly to the design and location of ports or vents that tune the enclosure. The loudspeaker system has an enclosure, having a front baffle and a pair of loudspeaker drivers mounted in the baffle. The enclosure has a hexagonal cross-section. A pair of vents are each located at a juncture of the vertical side edges of the front baffle and its adjoining panels. The vents lead into the enclosure via a conduit, which ends in an inlet. The inlet is positioned within the enclosure to face the rear of the loudspeaker driver. By this arrangement high to mid frequency sound waves radiated within the boundaries of the enclosure and entering the inlet are substantially attenuated in the conduit and low frequency sound waves radiated within the boundaries of the enclosure are reinforced with sound waves directly radiated from the front of the loudspeaker driver.

Abstract: An  improved tool for pulling off a rotor of  a  motor from  a  shaft or a fan from a shaft, which  improved  tool  is provided with hooked arms that are releasably but securely held at one end in the housing, without the use of retaining  clips, so that the arms do not fall off during use or become lost, and so  that  they do not interfere with the use of the  tool  when using the securing bolts for pulling off a rotor.  The  hooked arms  of the invention are also hexagonal shaped, and  securing bolts  are  provided with hexagonal-shaped  recesses  in  their heads,  so  that  the hooked arms may themselves  be  used  for rotating the securing bolts when pulling off a rotor of a motor from a shaft. To ensure that the each hooked arm is  releasably retained  in  a respective hole of the housing, the end of  the arm  is  provided  with  a hook defined  by  a  straight  piece extending  at  an  acute  angle with  respect  with  the  main, elongated body of the arm.

Abstract: The device comprises a driving hub (4, 18) coaxially connected to one shaft (20) and oscillatably engaging a number of planetary gear elements (8, 25) homogeneously distributed around the axis of said hub. The planetary gear elements (8, 25) are engaged between a driven crown wheel (6, 21) which is coaxially fastened to a second shaft (3, 23) and an intermediate crown wheel (7, 24) oscillatably linked to the driven crown wheel (6, 21).
