Abstract: Apparatus 500 for storing a variable quantity of strand material 200 comprises a generally cylindrical drum 110 that stores a layer of elongated strand material around its exterior surface. The layer is formed by wrapping the strand material in adjacent convolutions around the exterior surface which is energized to move in a direction which is parallel to the central axis 101 of the drum. Consequently, the strand material also moves in a direction that is parallel to the central axis. A winder assembly 510 is mounted on a first shaft 140 at an input end of the drum, and includes a strand payout member 511 for depositing strand material onto the drum. The drum is mounted on a second shaft 150 which contains the common support structure of the drum and the equipment for energizing the exterior surface. An unwinder assembly520 is mounted on a third shaft 160 at the output end of the drum, and includes a strand-receiving member 521 for removing the strand material from the drum. The shafts are coaxial with each other and each is capable of independent rotationalmovement. Accordingly, the volume of strand material stored on the drum may be varied by changing the relative rotational speeds and directions of the different shafts. In this manner, the volume of strand material can be varied in order to buffer speed variations along a manufacturing line.

Title: Selectable grade and uniform net shoe force braking for railway freight vehicle
Inventor: HART JAMES E
IPC: B60T8/24
Filed: 1996-07-23
Granted: 2000-09-26
Abstract: A railway freight brake method and apparatus for operating vehicles in a freight train having a locomotive and a number of railway freight vehicles wherein the individual railway freight vehicles can be controlled in a grade descending mode. When desired, such as when the locomotive transmits a grade mode signal to the individual vehicles, the individual vehicles can brake to produce a generally uniform net shoe force on the wheels of the vehicles. The generally uniform net shoe force can be limited on each vehicle to a value or ratio, such as a percentage of net braking ratio of the given vehicle. On-board calculations can be done in a microprocessor to calculate the vehicle brake cylinder pressure corresponding to the desired net shoe force. This calculation can be done using car parameters stored on-board the vehicle.

Abstract: A method of producing a container (201, 231 350) having a plurality of apert ures (e.g. 202, 232, 352) each containing a respective dose of powdered material, such as a medicament, involves placing an empty c ontainer in a position in which its apertures communicat e with a reservoir (216, 84) of powdered material. The material is then passed , for example by the flow of gas, from the reservoir int o the apertures to fill the latter, and the container is then separated from the r eservoir and the apertures are optionally sealed with sh eet material (204, 206, 321, 323). Since the apertures are filled, their volume determine s the amount of each dose which therefore does not have to be measured prior to introduction into the apertures. The container may compris e a rigid or flexible plate and in latter case can be su bsequently rolled into the form of a cylinder for use in an inhaler. Apparatus for perf orming the method, and an inhaler for use with a cylindr ical container, are also shown.

Abstract: A sensor for determining the surface or interface level of a material comprising a transceiver (12) and an inner conductor (21) of a coaxial cable (16) electrically coupling the transceiver (12) to a guide wire (14) partially immersed in the material. A launcher plate (18) is connected to the outer shield (19) of the cable (16) and an impedance (20) connects the launcher plate (18) to the guide wire (14). The launcher plate (18) produces a fiducial pulse back to the transceiver (12).  Electromagnetic waves transmitted from the launcher plate (18) propagate along the guide wire (14). The waves are reflected by the surface or interface, received by the laucher plate (18) and transmitted as reflected pulses to the transceiver (12). The transceiver (12) determines a time delay between the fiducial and reflected pulses to establish the surface or interface level relative to the launcher plate (18).

Abstract: A lotion composition for imparting a soft, lubricious, lotion-like feel when applied to tissue paper in amounts as low as from about 0.1 to about 15 96 by weight, and tissue paper treated with such lotion compositions are disclosed. The lotion composition comprises plastic or fluid emollient such as petrolatum, or a mixture of petrolatum with alkyl ethoxylate emollient, a solid polyol polyester immobilizing agent to immobilize the emollient on the surface of the tissue paper web and optionally a hydrophilic surfactant to improve wettability when applied to toilet tissue.

Abstract: Cette invention se rapporte de manière générale à des matériaux d'étanchéité destinés à des unités de vitrage isolant. Plus spécifiquement, cette invention est un matériau d'étanchéité monocomposant pour vitrage isolant, appliqué à chaud et durci chimiquement, destiné à l'étanchéité des bords d'unités de vitrage isolant. Ce matériau d'étanchéité contient une résine thermoplastique thermofusible mélangée à une résine durcissant au contact de l'atmosphère. La résine thermofusible, qui constitue le composant fusible au cours de l'application initiale, se solidifie instantanément en refroidissant. La phase polymère commence alors à durcir par réaction avec l'oxygène et/ou l'humidité atmosphérique pour former un élastomère thermodurci réticulé qui résiste à la chaleur. A ce stade, la résine thermofusible sert d'agent plastifiant inerte dans la phase polymère durcie. Le matériau d'étanchéité de la présente invention peut également comporter des agents du type plastifiants, matériaux de remplissage, pigments, catalyseurs et autres composants analogues.
