Abstract: The exposed welt of a footlet-type sock is divided by knit construction into a rear portion and a front portion. The rear portion, which is substantially the rear half, is of a substantially freely and outwardly rolled construction. The rolled rear portion is not tacked down and encircles the lower ankle area when emplaced on the foot. The remainder or front portion includes an upper edge which is tacked down in a controlled folded construction. The rear portion is thus left free to roll upon itself into a relatively heavy, thick mass of material. The front portion, on the other hand is folded across the instep of the wearer minimizing the thickness of material beneath the shoe tongue. The rear half is a knitted fabric formed with a combination of body yarn and elastic yarn. The elastic yarn forms the backing fabric for the body yarn, which itself is formed into terry loops.

Abstract: This invention relates to a method and apparatus for adjusting a stroke length of a ram for a press. The stroke length of the ram is adjusted with respect to a base point. The hydraulic pressure level in the acting chanber is also adjusted. The press is generally used for bending metal sheets. By this invention, an optimum stroke length of the ram in the press can be easily determined without experimentally processing and, therefore, wasting sheet metal workpieces.

Abstract: The ram of a hot-stamping press is driven by means of a movable rack that can be allowed to change position with respect to the ram. The rack engages gears on the end of the ram opposite its head, but during the initial portion of its stroke an air cylinder interior to the ram prevents relative motion between the movable rack and the ram. As a consequence, the ram moves at the same velocity as that of the rack during the initial portion of the stroke. Stationary racks are also provided, and additional gears mechanically linked to the gears engaged by the movable rack begin to engage the stationary rack toward the end of the stroke. This requires relative motion of the movable rack relative to the ram despite the force applied by the air cylinder inside the ram, and the velocity of the ram is thereby reduced to a fraction of that of the rack. This results in force multiplication toward the end of the ram stroke.

Abstract: Hermetically sealed electronic articles (11) such as, for example, diodes are leak tested by exposing the articles to a fluid (28) under pressure. The fluid is capable of altering the electrical characteristics of the articles to a value outside of an acceptable range of values upon penetrating through faulty hermetic seals of the articles (11). After such exposure the articles (11) are routinely tested and the articles with values of their characteristics outside the range of acceptable values are identified or discarded. Ethylene glycol is an example of a preferred fluid (28) in that it has conductive properties which significantly increase the reverse bias leakage current of the diodes.

Abstract: In order to determine the proportion of particles of less than a predetermined size in a fluid suspension, the fluid suspension is placed in a vessel (1) and is thoroughly mixed therein by mixing means (36,37). A sample of suspension is then withdrawn from a predetermined level within the vessel (1) by means of a sampling tube (9) and is transferred by way of a flexible tube (22) to a container (15). The particle concentration of this sample is then monitored by passing x-rays from a source (17) through the container (15) and detecting the emerging x-rays with a detector (18). The sample is then drained from the container (15). After allowing the suspension in the vessel (1) to settle for a time sufficient to enable particles of said predetermined size to sink from the surface of the suspension to said predetermined level within the vessel (1) according to Stokes' law, a further sample of suspension is withdrawn from said predetermined level and transferred to the container (15).

Abstract: The moment sensitivity of shear beam transducers is mechanically compensated to make such transducers relatively insensitive to load applications which are off-center relative to an optimal point of load application. Such shear beam transducers have a free end forming a load application section, a mounting section, and a fillet located substantially where the sections merge. The compensation is made by providing the fillet initially with a larger radius than the final compensating radius. The compensation is made by gradually changing the fillet radius until the transducer output shows substantially no difference between the measurement resulting from applying a defined load in the optimal loading point and the measurement resulting from applying the same load off-center the optimal loading point whereby the transducer becomes substantially insensitive to such off-center load applications.

Abstract: A low pressure drop air flowmeter (10) for an automobile engine is disclosed. The meter contains a main air flow passage (24), a relatively small venturi (20) to receive a portion of the air flow, pressure ports (98a and 120) for sensing stagnation and static pressure and a set of swirl vanes (22) disposed adjacent the outlet of the venturi and operative to impart a swirl to the remainder of the air in the main passage, thereby creating a reduced pressure at the venturi outlet for amplifying the pressure difference between the stagnation and static pressure without appreciably increasing the pressure drop across the flowmeter. A tertiary passage (28) provides a path of fluid communication between points upstream and downstream of the swirl vanes. This passage includes a flow restricting throat (29) which is manually calibrated during or after assembly. Air exiting the tertiary passage impinges upon the swirl to modulate the vortex velocities.

Abstract: A railroad hand brake includes a spring clutch interposed between an operating hand wheel and a gear drive for the chain drum. The clutch includes a spring cooperating with a control drum and with an output drum connected to the gear drive. An input element is rotated by the hand wheel in a forward direction to energize the spring so that the input element, the control drum and the output drum rotate as a unit to take up the brake load. A ratchet and pawl prevent reverse movement of the control drum in order to maintain the brake load applied when the hand wheel is released. When the hand wheel is rotated in the reverse direction, the input element tends to deenergize the spring, and the brake load is gradually released with a clutch action characterized by small input force and little wear. A quick release element operable with a small manual force abruptly uncouples the spring from the load drum in order to free the load quickly while the input element and hand wheel are stationary.
