Abstract: An improved suspension system for a vehicle wheel, and particularly for single track vehicle wheels as found in motorcycles and the like. The invention comprises an improvement in a vehicle having a wheel mounted for rotation upon a transversely extending axle, whereby the axle will be maintained perpendicular to the longitudinal plane of rotation of the wheel, regardless of vertical axle movement with respect to the frame of the vehicle. In the preferred embodiment, the pressure fluid is hydraulic fluid and the wheel axis is solely connected to the vehicle frame through the fluid pressure interconnection defined by the present device. The present invention allows only vertical movement of the vehicle axis. If the wheel is being urged out of alignment, as by side stress, there is a counter flow of hydraulic fluid from one hydraulic-piston into the diametrically opposite hydraulic-piston chamber, thereby realigning the axle so that it remains perpendicular to the longitudinal plane of rotation of the wheel.

Abstract: A process for producing a drawing stencil characterized in that a plastic border edging is applied, by a spray or injection molding, upon a preformed stencil sheet. A further feature disclosed is the use of a lubricated interface between a border edging and a stencil sheet, to relieve stress buildup and resultant distortion of the stencil.

The lift table includes a scissor jack linkwork, and can be easily positioned, as necessary, within a material handling space. The wheeled truck includes means to engage guideways on the lift table assembly, as the truck is wheeled thereover to its selective engagement position.

Abstract: A disposable ink reservoir cartridge which is attachable to tubular writing pens of the stylographic type embodying a pressure compensating chamber. The reservoir cartridge is characterized by its axial deformability, such that the free volume of the reservoir may be reduced, as ink flows from the reservoir into the pressure compensating chamber during pen use. The reduction in free volume of the reservoir eliminates available air space and, thereby, avoids the deleterious effects of air pressure changes upon the ink or writing fluid, as the reservoir is depleted.

Abstract: A capillary writing pen of the type having an expansion or compensation chamber intermediate the ink reservoir and ambient air. The expansion chamber is improved such that inadvertent flowing of ink from the reservoir to the capillary pen tip due either to pressure or temperature changes is avoided. The interior wall of the expansion chamber is profiled as a contiguous series of transverse indentations which extend circumferentially about the tubular pen body to provide successive expansion areas for entrapment of air and constrictive areas where menisci of ink are formed. The forming of the menisci entraps air bubbles within the ink and, accordingly, provides increased resistance to capillary flow of ink.

Abstract: An improved device for easy attachment to an external water spigot, which is designed to allow a slight dripping of water when ambient temperatures drop below a point at which there is a danger of water freeze, within house pipes or spigot. The present device has a simple moving valve, or water release shaft, which extends axially between a closed volume of a particular fluid, and a valve seat proximate the connection of the device to the spigot outlet. The improved temperature responsive valve taught herein ensures a most efficient opening function, during temperature drops below approximately 32.degree. F. by employing a closed fluid volume that is unaffected by the temperature of any released water. Further, the particular improvements involve a specially configured liquid chamber piston which ensures a large opening excursion, at desired temperature range.

Abstract: Cylindrical method of quantifying fugitive emission rates from pollution sources, such as those emanating from ore mines, factories, office buildings, and the like.The method is characterized by its ability to quantify airborne fugitive emissions by defining an arcuate profile of pollutant flux, while driving a pollutant sensor in a peripheral arc surrounding the pollution source. According to wind changes, the pollutant sensor may be advanced peripherally of the pollution source to an arcuate detection plane downwind, so as to quantify fugitive emission rates, regardless of source emission characteristics or wind direction.

Abstract: An improved kit for an ostomate, comprising a drainable stoma bag appliance of the type consisting of a flexible, vertically elongated member with a closed top end for attachment to the stoma of the patient, with a downwardly open bottom end that is openable for flushing. The present invention comprises such a stoma bag appliance together with a novel directional water flushing appliance consisting essentially of a hand-operated positive shut-off valve member for actuating a water outlet tube which is a rigid J-shaped tubular conduit, with a distal end including a directional spray orifice. With the present kit, an ostomate may greatly facilitate directional flushing of the stoma bag, since the ostomate can manipulate a directional flushing action to selected portions of the interior of the stoma bag, without danger that the seal between the stoma bag and the stoma of the patient will be broken.

Abstract: A self-contained device for selectively discharging a pressurized gas within a hermetically sealed vessel to which it has been sealed, to enable a leak testing of the vessel. A linear actuator is functioned to open a small, high pressure cylinder that has been charged with a detector gas. The mechanism is preferably mounted to the interior of a lid which is then sealed onto the vessel which is to be tested. Proper functioning of the device may be confirmed electrically, since circuit continuity between an electrical contact pin and at least one additional portion on the exterior surface of the vessel will be permanently broken after proper functioning.

Abstract: Method of regulating ink flow in automatic drafting pens of the type supporting a plurality of stylographic pens in parallel, including pumping ink from a reservoir into the writing pen capillary tubes, gauging the level of ink intermediate the reservoir and the capillary tubes and modifying said pumping as the gauged, actual level of ink flow may deviate from a desired level of ink flow. The method includes buffering of ink flow into the capillary tubes, so as to overcome the effects of inertia (when the pen is not writing), as well as the surge of ink flow under pumping pressure.

Abstract: A baffle for use in rotary newspaper printing press ink reservoirs. In such ink reservoirs the inking cylinder, while rotating at high speed contacts ink within the reservoir. Conventionally, the high speed rotation of the inking cylinder creates vibrations and turbulence in the ink, such that air is forced between the rotating surface of the inking cylinder and the printing ink, causing bubbles and non-uniform inking of the ink cylinder. The present system includes a series of baffles positioned within the ink reservoir so as to inhibit turbulence and enhance the flow of ink onto the surface of the rotating cylinder.

The inspirator in its multi-fuel mode has a plurality of series of axially spaced orifices, additional series being opened upon axial extension of the inspirator into the mixing throat.

Abstract: A constant speed actuator significantly characterized by being able to produce a displacement at constant speed, even though the loading on a hydraulically damped piston is substantially varied. The actuator consists of a pneumatic driving pressure which acts against a volume of hydraulic fluid, through a interface with a free piston. The hydraulic fluid, thus acted upon by the pneumatic pressure, flows to the opposite side of the hydraulic load piston through a hydraulic fluid by-pass at a constant volumetric rate regardless of the loading on the hydraulic piston. The constant volume by-pass flow is automatically controlled by employing a constant volume valve in the by-pass. Consequently, a consistent, predictable speed of actuation is achieved over a wide range of hydraulic piston loadings and pneumatic supply pressure.
