Abstract: A inhalation-actuable dispensing device is provided for dispensing a metered dose of medicament in aerosol form. The device comprises a compartment (6) for receiving a metered dose aerosol container (10) having an outlet tube (12) at one end. The device has a storage chamber (13; 120) which receives a metered dose from the container. The storage chamber (13; 120) has an outlet which is closed by a valve member (44; 124) under the pressure of the dose within the storage chamber. Inhalation by a user causes a dose releasing device (34, 40, 46; 138-140) to move the valve member to an open position.

The cover carries ramps which engage the fitments on closing to insure seating thereof. An output restrictor is releasably received on the back plate for limiting the stroke of a pressure applying handle carried by the cover.

Abstract: An apparatus for continuously applying tags to rings or the like includes at least one conveyor having a series of ring carrying posts movable into registry with a tag applicator which receives a tag from a supply source, is insertable into the ring and collapsible about the ring to position the tag about the ring and then movable out of the ring. The tag applicator includes a pair of applicator arms movable between an open, coextensive position to receive the tag and a closed, juxtaposed position to place the tag about the ring. Carousel supply means are disclosed which include ring carrying posts movable to a position wherein rings may be selectively deposited on the ring carrying posts. The method includes operating the conveyor continuously, supplying rings to the ring carrying posts, supplying tags to the applicator arms, inserting the applicator arms into the rings and affixing the tags to the rings and retracting the applicator arms.

Abstract: A flow restriction controlled variable engine valve system includes a housing slidably mounted in the engine housing and movable therein in response to movement of an engine cam. A sleeve is telescoped within the housing in fluid communication with the engine oil supply and a portion of the housing. A control rod is carried by the sleeve and projects into the aforementioned portion of the housing to restrict fluid flow therebetween. A check valve is carried by the housing and closes off the fluid communication between the housing and the sleeve after movement of the housing in response to cam movement to lock up the sleeve and housing for further movement together with the sleeve being operatively connected to the valve to open it upon further movement of the locked up sleeve and housing. A velocity reduction spring is interposed between the sleeve and the valve.

Abstract: A double diaphragm pump includes a connecting shaft for interconnecting the opposed diaphragms mounted in the pump body for reciprocal movement relatively thereof and a pilot valve sleeve telescoped over the shaft and movable axially in response to movement of the connecting shaft and having a plurality of axially directed circumferentially disposed recesses thereon for fluid transfer through the pilot valve cavity. A spool valve assembly is also carried by the body in a cavity which is in selected fluid communication with a source of air pressure, the pilot valve, the atmosphere and the pressure chambers of the pump. The pilot valve sleeve also has at least one projecting annular rib which engages the usual O-rings of the cavity in which the connecting rods and pilot valve sleeve reciprocate for assisting movement past the O-rings in response to pressure from the spool valve.

Abstract: A self-contained fan turret unit for use with a tower air recirculating system includes a housing positionable for attachment to the tower system. The housing includes an extendable column assembly bearing a turret assembly to which are attached one or more fans, inlet bells and discharge cones with the turret assembly being movable from a position within the housing to one above the housing by the column assembly. The turret is supported by an air spring isolator and, when extended, is connected to the housing and the tower unit by flex joint isolators. A cowling is also provided for releasable attachment to the turret. The turret is rotatable and extendable arms are provided to interconnect the column assembly and the fans for selective removal thereof from the turret.

Abstract: An adaptor assembly for an earth boring machine includes a thrust bearing housing removably attachable to the bulkhead plate of an earth boring machine surrounding the torque hub flange. A rear drive flange is attached to the torque hub and a front drive flange is mounted within the housing and carries a thrust bearing movable into and out of contact with the housing. The front drive flange has an extension which projects beyond the housing for attachment of an auger and boring head and is connected to the rear drive flange for rotational movement therewith and axial movement relatively thereof.

Abstract: A package for displaying and presenting jewelry includes a planar base having foldable top flaps secured to its periphery whereby the flaps may be folded over the base to provide a closed package. One or more pairs of through slits are provided in the base and a ribbon is threaded through the slits so that part of the ribbon provides a means for securing the jewelry to the base and the remainder of the ribbon may be wrapped around the closed package to secure it. Some of the top flaps may be provided with an inter-engaging lip and slot to secure the flaps in the closed position and the outer surfaces of the base and top flaps may be decorated.

Abstract: A dental irrigating and aspirating instrument utilizes a cannula with a reduced diameter extended member shaped to occlude the apical foramen while conducting irrigating fluid into the apical terminations of root canal preparations. The extended member also serves to occlude the apical foramen while conducting fluid and debris out of the apical regions during aspiration. The extended member can be shaped with a cutting surface to prepare a base for the root canal preparation and root canal filling. Use and fabrication of the instrument for irrigation and aspiration of the fullest depths of the gingival sulci and periodontal pockets in periodontic practice is also described. A handpiece is described that retains the instrument allowing manipulation of the instrument and control of fluids to and from the instrument.

Abstract: In order to present patients in the correct position for surgical or investigative procedures and in order to reduce the time required to place on and remove from operating surfaces on which such procedures are carried out on patients, a wheelchair of novel configuration is described. The wheelchair has a seating arrangement comprising a back rest portion, a seat portion and foot rest means, adapted to receive a patient in a semi-recumbent or sitting position. The seating arrangement can be tilted so that the back rest portion is substantially horizontal and the seat portion is divided so that the patient's legs can be moved apart, while still supported, to present the patient's ano-genital region for surgical or investigative procedures.

Abstract: A continuous grinding system for comminuting material in a liquid includes a grinding vessel and a rotating shaft carrying one or more mixing arms disposed within the vessel. A funnel-shaped housing and a cylindrical extension project into the vessel and the rotating shaft extends through the housing and the extension with the mixing arms being disposed beneath the extension. The rotating shaft also carries one or more radially projecting, angled impeller blades which are disposed within the extension. The blades may engage the extension in which event the extension may be separate from the housing or may terminate short of the inner wall of the extension in which event the extension may be secured to the housing. The cylindrical extension in a modified form of the invention extends into the housing a distance equalling from about 10% to about 75% of the depth thereof and preferably from about 50% to about 55%.
