Abstract: Abstract LEVER CONTROL APPARTUS        Abstract A vehicular lever control apparatus includes two relatively movable levers, a first being constrained to pivotal movement about a first axis and having a multiple position switch affixed thereto.  A second lever is pivotally connected to the first lever and moves axially therewith as well as transversely about a second axis perpendicular to the first axis.  Transverse movement of the second lever actuates the switch on the first lever.  In a preferred embodiment, the switch is a three-position electric toggle switch for selection of reverse, neutral and forward modes of a transmission. Movement of the second lever about the first axis thus causes like movement of the first lever, which effects changes of gear ratios in a continuously variable speed transmission.  The second lever thus acts as a dual function control lever for (1) varying speed ratios when moved about the first axis, and (2) selection of transmission directional modes when moved about the second axis.

Abstract: ABSTRACT OF THE DISCLOSURE             A shrinkable polyamide film useful for wrapping hams, sausages, etc. The shrinkable film has a hydrothermal shrinking ratio of at least 30% in both MD and TD and a hydrothermal shrinkage stress of from 300 to 700 g/mm2. The film is produced by a process which comprises biaxially stretching a substantially amorphous film composed of a copolymer of 6,6-nylon/6-nylon in a weight ratio of from 5/95 to 25/75 at a temperature of not higher than 120°C and at a stretching ratio of at least 2.5 times in both MD and TD, and subjecting the stretched film to stress relaxation at a temperature of from the stretching temperature to 170°C, followed by winding it up. Further, a shrinkable film having an oxygen gas permeability of not more than 20 cc/m2 24 hrs. atm. as well as the above properties may be obtained by coating a polyvinylidene chloride resin prior to the stretching so that its solid content after the stretching becomes to be at least 0.5 g/m2.

Granted: 1985-06-18
Abstract: ABSTRACT          The circuitry required to obtain a pair of quadrature square waves which form a high resolution angle designating signal in an incremental encoder is reduced by use of a quadrant switched multiplier.  The bits of a multibit binary word are gated with a coarse index taken from the code disc to provide a completely addressable precise index having a resolution matching that of the quadrature pair.  The multibit binary word includes square waves already available in the multiplier and an additional bit obtained from a logical combination of the pair of quadrature signals.

Abstract: ABSTRACT          A system of rolls for use in a calender, printer or rolling mill has a pair of rolls at least one of which has a hollow cylindrical shell with an elastically deformable liner.  The shell surrounds a stationary carrier and confines a row of electromagnetic or hydraulic force applying devices which can be adjusted individually to thereby regulate the pressure between the two rolls and hence the temperature at the exterior of the liner.  Such temperature is monitored by one or more sensors, and the signals from such sensors are processed by a computer which regulates an adjusting unit for the force applying devices so that the pattern of temperatures along the external surface of the liner matches an optimum pattern.

Abstract: ABSTRACT OF THE DISCLOSURE A molded, polyethylene valve body has a flow passage connecting an inlet with an outlet of the valve body.  A valve seat, formed integral with the valve body, surrounds the passage and a plastic valve disc is rotatably positioned in the passage for movement into and out of sealing relation with the valve seat to effect closing and opening of the passage between the inlet and outlet.  A valve stem is nonrotatably oonnected at one end to the valve disc and extends through the valve body and projects upwardly therefrom to an upper end portion.  An actuator cap is nonrotat-ably connected to the valve stem upper end portion.  An external valve neck portion surrounds the upper end portion of the valve stem and is positioned on the outer surface of the valve body. The neck portion is adapted to rotatably receive and support the actuator cap.   A pair of clamp-like  leg members of  the neck portion extends circumferentially around the surface of the valve body to connect the neck portion to the valve body.  Free end portions of the leg members are brought under tension to maintain the leg members in gripping engagement with the valve body so that the actuating forces from the actuator cap are transmitted from the neck portion and leg members uniformly around the surface of the valve body.

Abstract: Abstract of the Disclosure An improved female urinary appliance is disclosed. The appli-ance includes a mouth surrounding a urine-receiving cavity, and a drainage channel integral with the backside of the device and communicates with a bore opening from said cavity.  The device includes means for preventing the drainage channel from kinking.          The mouth is adapted to be positioned within the labia folds of the user, in contact with the vestibular tissue around the meatus and held in place by gentle vacuum.  A valve is preferably used in combination with the appliance, and includes an inlet and an outlet, for maintaining a preselected vacuum condition at the valve inlet and a predetermined pressure condition at the valve outlet is disclosed.  In preferred use, the drainage channel is suitably connected in spaced relation to the valve inlet.  The valve contains a flow control element adapted to control flow of urine from the cavity.  While the mouth is held against the vestibular tissue by gentle vacuum, urine flowing through the appliance and valve entrains gas present in the cavity.  In the cavity, a desired vacuum condition is maintained, over time, because the valve  includes a semi-permeable membrane adapted to permit air and other gas to diffuse thrugh a portion of the valve and thereby to counteract the effects of entrainment and relieve or maintain the vacuum condition at a predetermined level.
