Abstract: ABSTRACT OF THE DISCLOSURE       An electronic postage meter is disclosed which comprises a plurality of print devices each individually settable to a desired position so that the print devices may print a desired postage value; a plurality of d.c. motors, one for each of the plurality of the print devices, a different one of the d.c. motors being coupled to a different one of the print devices for setting the respective print device to a respective desired posi-tion; actual position sensing means for providing signals related to the actual positions of the print devices; and a microcomputer coupled to the d.c. motors and to the actual position sensing means.  The microcomputer in response to signals from the actual position sensing means, a desired postage value and programming of the microcomputer sequentially controls the d.c. motors to set the print devices to respective desired positions for printing the desired postage value.  The control loops include low cost, low bandwidth incremental quadrature encoders.  The drive ratio of the d.c. motors is reduced, and the encoders sense the actual position of the print devices at a point in the reduced drive ratio, i.e., on the load side of the d.c. motors.  The print devices are mounted to a print drum whose rotated position is sensed at its shaft.

Abstract: Canada SV-251 (35-INDUSTRIAL SWEEPER            ABSTRACT OF THE DISCLOSURE          A surface sweeper may include a first pulley driven by the motor, a second pulley on a drive shaft for driving the drive wheel, a third pulley for driving the main brush, and a drive belt interconnecting the first and second pulleys which can be selectively tightened by a clutch for driving the drive wheel.  Preferably the drive belt has inherent stiffness whereby it spontaneously loosens unless held in its tightened condition by the clutch.  The driveshaft advantageously has two parts separated by a gap, for permitting the drive belt to be placed around the driveshaft without removing the driveshaft from its mount.  The two parts may be connected by a sleeve which is biased by a spring into position for drivingly engaging the two parts, and which is slidable out of said position for revealing the gap.  The main brush may have structures at its two ends that are similar to each other, for being reversibly mountable in first and second brush bearings.  One of the brush bearings may include a structure upon which the main brush can pivot into and out of operating position, the other brush bearing having a lock for locking the main brush in its operating position.

Title: Device for the administration of powdered medicinal substances
Inventor: CHIESI PAOLO
IPC: A61M11/00
Filed: 1991-04-11
Abstract: Abstract DEVICE  FOR  THE  ADMINISTRATION  OF  POWDERED MEDICINAL            SUBSTANCES      This invention relates to a new inhaler for the local administration of powdered drugs to the respira-tory tract. The apparatus consists of a nozzle and a main body which itself defines a storage chamber for the medici-nal substance,  a dosing means which supplies precisely measured doses  of  the  drug  and  a  dispensing  system which pours the dose of the drug delivered into a col-lecting chamber.     The  cavity  of  the  nozzle  communicates  with  the collecting chamber through a central channel designed to reduce air flow resistance as much as possible.     Lateral holes provided in the body of the inhaler allow for the passage of air from the outside. Upon inhalation, a negative pressure is created in the chamber in which the dose of powder delivered is collected, drawing an air inflow from the outside.     The air flow is mixed with the medicinal substance particles and through the central channel, enters the cavity of the nozzle from where it is directly inhaled.

Abstract: TWO-PIECE OSTOMY APPLIANCE AND COUPLING    THEREFOR WITH ROCKING WEDGE LOCK                 Abstract of the Disclosure A two-piece ostomy appliance having a pair of coupling rings that detachably connect a collection pouch and an adhesive faceplate.  One of the coupling rings, preferably the faceplate coupling ring, is provided with a substantially non-compressible insert that includes an axially-extending collar, a bulbous non-deformable wedge body, and a radially-extending pivot stem that centrally connects the collar and wedge body.  The pivot stem allows limited forward and rearward rocking movement of the wedge body about a pivot axis extending through the stem.  A massive front portion of the wedge body has an inwardly and rearwardly curved bearing surface of progressively increasing distance from the pivot axis so that the radial width of the insert decreases as the wedge body rocks rearwardly and forceably increases as it rocks forwardly about the axis, in response to frictional engagement with the walls of the channel, when coupling and uncoupling forces are exerted on the rings.
