摘要： 370,429. Feeding webs. PFEIFFER, F. E., 2124, Malvern Avenue, and PFEIFFER, W. C., 1045, Dodgson Court, both in Dayton, Ohio, U.S.A. Oct. 6, 1930, No. 29918. Drawings to Specification. [Class 100 (i).] A device for feeding a number of paper webs comprises a belt or similar conveyer and a series of guide rollers, one for each web, the webs, which are fed to the device in superposed relationship, passing separately over the guide rollers and into engagement with the conveyer, means being provided to adjust the webs longitudinally into a predetermined relationship as they are engaged by the conveyer. The invention is particularly for use in a manifolding machine and such a machine embodying the device is described in Specification 370,428.

摘要： 370,428. Feeding webs. STERN, M. C., 212, North Main Street, and PFEIFFER, W. C., 1045, Dodgson Court, both in Dayton, Ohio, U.S.A. Oct. 6, 1930, No. 29917. [Class 100 (i).] In a manifolding machine in which record sheets in the form of a number of superposed webs having spaced perforations are fed over a platen, the web-feeding means is operated by an electric motor which is automatically stopped when the webs are fed the length of a record sheet, the leading ends of the webs being held stationary during the feeding movement. The feeding mechanism is carried by a frame 18, Fig. 1, attached to a frame 15, the upper end of which carries a platen over which is movable a typewriter 12. At the front end of the platen is arranged a bar against which the issuing sheets may be torn from the webs and which normally clamps the leading ends of the webs to the platen but may be raised on depression of a pedal 27. The webs 90 .. 96, Figs. 1, 3 and 4, pass from a roll 16 round a guide roller 97 and thence pass separately round a series of guide rollers 100 on to a pair of spaced endless conveyer bands 48 provided with feeding lugs 55 which engage in succession with the p rforations in the separated webs and bring them into exact registration longitudinally. The bands 48 pass round rollers 47, 49 and the shaft 46 of the roller 47 is driven through change-speed gearing from an electric motor 37, Fig. 1, which is provided with any suitable means for stopping it automatically after a predetermined rotation of the shaft driven thereby. The motor is started by the actuation of a switch arm 61 by a push rod 60. The length of webs fed forms a loop 106 between the frames 18, 15. The webs are unwound from the roll 16 by a pair of feed rollers 73, 74 engaging the web 90 and driven by gearing 70, 71, 72, 75 from the shaft 46. The rollers 73, 74 are pressed together by a spring 78 and may be separated to facilitate threading of the web by turning a shaft 85 carrying a cam 86 engaging in a slot in a member 76 carrying the roller 74. A brake roller 18a rests upon the roll 16 which is mounted in supports 20 having inclined edges over which the roll can be rolled into the open bearings 22. Specification 370,429 is referred to.

摘要： The present invention is directed to state-of-the-art medical devices using smart materials and related emerging technologies under development for robotics. In particular, the present invention is directed to the development of rehabilitative (i.e. prosthetic, orthotic, surgical) devices actuated by smart material artificial muscles to increase the dexterity and agility of an artificial limb or a dysfunctional body part, so that movement of the limb more accurately simulates movement of a human appendage. A kinetic assistive device is provided is provided which is constructed of a lightweight material (such as aluminum) and has a plurality of smart material actuators attached thereto. A system for detecting environmental stimulation of the device is provided in electrical communication with such actuators to effect movement of said device in response to detection signals produced thereby. The system includes a plurality of sensors, such as proximity detectors, accelerometers, tactile sensors and the like which are mounted on the assistive device and which provide data to computer-controlled command circuitry. This data can be encoded and used to control the movement of the assistive device via the actuators to more accurately predict the performance of the device in relation to that of an actual human limb.
