Abstract: A letterpress printing press is provided using an anilox form roller, to directly receive by gravity thereon, a viscous ink from an ink supply in ink fountain means that are positioned immediately above the form roller. The ink is of the type to be substantially immediately dried by being exposed to ultraviolet light. So as to control the amount of ink delivered from the anilox form roller to a printing plate, there is provided a doctor blade means located within the ink fountain means. The doctor blade means includes both a vertically slidable plate, whose vertical position is selectively controllable by means operatively associated with the plate and fountain, and a doctor blade that is cantilevered from the vertically slidable plate so as to have its relatively unsupported, and relatively flexible, free edge engage the surface of the anilox form roller to scrape excess ink from the form roller and restoring the removed ink to the ink supply in the ink fountain means.

Abstract: An improved method and apparatus for effecting mid-stream sampling of catheterized flow of liquid from a body cavity is effected through use of an improved coupling between sections of catheter tube means. The improved coupling includes a tubular cross-member that provides two pairs of oppositely extending tubular arms, a first pair of arms adapted to connect to the portions of the catheter tube means, and with a valve member constructed and arranged for selective reciprocal movement in the other pair of tubular arms and so as to permit usual drainage in one position or to provide, in said second position, means for effecting diversion of flow for effecting mid-stream sampling without separating portions of the catheter system that might permit contamination. In the second position, the constructions permit of effecting a backflow flushing of the body cavity, or application of medication, or an instrument, through the improved coupling into the body cavity.

Abstract: A medical suction device is disclosed which includes a vacuum indicator flag. This flag is made up of a flexible tube capped with a plug. The rigidity of the walls of the tube is chosen such that the walls collapse when the pressure inside the tube falls below a predetermined value, thereby allowing the flag to droop. In addition the rigidity of the tube serves to hold the flag upright when the pressure inside the tube rises above a second predetermined value. Thus the state of the flag (upright or drooped) provides a remote indication of the pressure being developed by the suction device. In addition, the suction device uses a constant force coiled ribbon spring to provide substantially constant suction as the suction device is filled. Furthermore, the suction device includes a plurality of separately valved drainage receptacles which can be folded and stored compactly against the drainage device.

Abstract: An add-on roof reinforcing brace is disclosed for buttressing the structural strength of roof rafters which have been weakened by age and deterioration. The add-on brace of the present invention provides a quick and economical means of vertically orientating a square-cut stud, between an angled roof rafter and a horizontally disposed ceiling joist. To this end, a joist attachment member secures one distal end of the stud to the ceiling joist and a rafter attachment member secures the other distal end of the stud to the roof rafter. The rafter attachment member includes a sleeve for attaching said rafter attachment member to the other end of the stud, a saddle-shaped member for attaching said rafter attachment member to a roof rafter, and a pivot member for pivotably interconnecting the sleeve and the saddle-shaped member.

Abstract: A handled spray with a lever for controlling flow therefrom is formed principally from molded parts, and with a spring that normally restores a flow control valve to its closed, or no flow, position. The discharge end of the spray body includes a cup-shaped closure with flow apertures therethrough. The cup-shaped closure cooperates with a ring-shaped insert shaped and arranged to provide for centering, and to support thereon a pair of concentric seals one of which provides a seal for the spray body, and the other seal providing a seal seat for the spring biased valve member that is selectively movable by the spray's handle to a position at which flow occurs. The valve member and handle are interconnected and assembled through a laterally opening recess, defined at the upstream end of the valve member, and telescopically receiving thereinto a laterally elongated knuckle formed integrally on the handle.

Abstract: A canister auger of inexpensive construction is provided by forming the handle and canister of molded plastic parts, so that only minimal portions of the assembly require metal parts. The construction and design provide effective bearings between the canister and the handle. The canister is formed by a pair of molded shells which are secured together by fasteners. The clamp for engaging the auger wire utilizes a thumb screw and standard nut of metal cooperating with plastic parts in such a manner that effective operation, at reduced cost of parts, is achieved.

Abstract: An energy saving vent is provided for selectively directing hot, moist exhaust air from a clothes dryer either through a downstream vent sleeve to the outdoors, or through a vent port to the indoors. The vent includes four major components principally molded from a synthetic plastic resin, the components being: an open sided housing; a closure panel for closing one open side of the housing; a valve member within the housing for selectively directing air through the housing in alternate paths; and a filter screen assembly for another open side of the housing. The selectively swingable valve carries a pressure relief means adapted to provide for passage therepast of pressurized exhaust gas when the valve is in its position to direct air flow indoors, and in the event that the flow of air indoors is blocked by the filter screen being clogged. The preferred filter screen is a truncated, basket-like, member that is carried on a frame which is removably carried in a slide channel defined on the housing.

Abstract: A key control system is provided by a frame that includes multiple slide channels for vertical movement therein of generally planar key rack members. Each key rack member is articulated to provide an upper key-holding section for selectively angled display of keys thereon. The key rack member may be stored away in a lowered position in the frame, or be moved to the display position, or be selectively removed from the frame.

Abstract: A radiant heat hair dryer is provided, using a disc-shaped casing in which is mounted a ring-like, infra-red radiator, together with reflector means for directing the infra-red radiation through a grille-like member, that is shaped and constructed to support a small, inexpensive, motor for a flat air fan that directs a gentle flow of air through the same grille-like member providing only slight movement of the hair to avoid disarray of the hairdo while permitting the radiant heat to penetrate into the body of hair. The infra-red radiator includes an elongated, helical heating wire positioned in a ring-shaped, elongated, quartz tube whose ends are supported on a ceramic mount, with a secondary resistance heater carried in the ceramic mount for providing convection heat to ambient air. The resistance heater is advantageously employed to reduce current drawn by the fan's motor, so that an inexpensive, direct current, motor may be employed.

Abstract: An aerator, that includes jet-defining slots and jet-fragmenting surface therein, formed in molded plastic parts, is provided with both self-cleaning character by using a movable valve member and a flow-directing washer of shape-retaining character upstream thereof, and with a noise reduction feature obtained by providing on the movable valve member a centrally located conical projection that, in the non-flow condition, extends through and upstream of the flow directing washer.

Abstract: An illuminated mirror device is provided as an aid to application of cosmetics. The mirror device provides two mirror-carrying wings that are pivotable between an open planar position and a closed, cassette-like, construction that conveniently provides the mirror device with character as a travel appliance. Pivoting of the wings is about a translucent tube that surrounds an electrically energized source of illumination, and which tube transmits light to the wings which, by reason of their character, guide light therethrough to the free edges of the wings from where illumination is directed toward the object that is to be seen in the mirrors. The wings are provided with inclined border surfaces from which light is reflected toward the object to be illuminated.
