Abstract: A B S T R A C T         A pole piece (14a) of the movable core (12) moves in an air gap (25a) between external (61) and internal (16) pole pieces.  A pole flange (14b) of the same core (12) moves in an air gap (25b) between a portion (30b) of the external pole piece (61) and a magnetic lobe (36) which is in contact with this latter.  A permanent return magnet (17) is disposed between the internal (16) and external (61) pole pieces.  The magnet (17), the internal pole piece (16) and the lobe (36) are maintained in a cage (60) of plastic material snap fastened by hooks (78, 80) on the external pole piece (61).  Three cross pieces (75, 76, 77) connecting two longitudinal walls of the cage to each other, suitably separate the different magnetic components. The force of attraction of the magnet (17) prevents the pole pieces (16, 61) from leaving it.

Abstract: "Star Topology Local Area Network"      ABSTRACT OF THE DISCLOSURE    A star topology local area network comprises a data bus, a receive-not-ready bus, a plurality of bus access units associated respectively with user terminals for receiving a request therefrom, and an arbiter for assigning priority to one of the bus access units when requests for transmission occur simultaneously. Each of the bus access units comprises a transmit buffer for storing a packet from the associated user terminal and forwarding it to the data bus when priority is assigned to it and a receive buffer for storing a packet from the data bus and forwarding it to the associated user terminal. An address filter is provided in each bus access unit to detect a packet addressed to it and applies a receive-not-ready signal to the receive-not-ready bus when the receive buffer has an insufficient capacity to receive the detected packet. A bus access controller is connected to the receive-not-ready bus for terminating the transmission of a packet in response to the receive-not-ready signal. The storage capacity of the transmit buffer is also monitored and a proceed-to-send signal is transmitted from the bus access unit to the associated user terminal indicating the permission of transmission when the detected storage capacity is sufficient to receive a packet from the terminal.

Abstract: Abstract An improved apparatus and method are provided for cutting a tire surface to remove selected portions of rubber from the tire surface while the tire is rotating.  The apparatus and method are especially useful in removing tread material from the tire to improve the force variation characteristics of the tire.  The material is removed by a cutting device such as a grinding wheel and a positioning device which holds the cutting device in a fixed cutting position for an incremental period of time while a corresponding incremental segment of the tire circumference, for instance a segment equal to 1/100 of the circumference (3.6°), passes by the cutter. A sensing device measures a characteristic of the tire, such as its radial force variation, and radial run-out of the tire is also measured.  Based on these measurements, a computing device determines the amount of material to be removed from each incremental segment of the tire circumference and controls the positioning device so that the cutter is located in the correct position for removing the desired amount of material from each incremental segment of the tire circumference.

Abstract: 03823.914 BEAM POWERED ANTENNA   ABSTRACT          The invention relates to an antenna for receiving and modulating transmitted signals having a very low power density on the order of below 1 watt per meter squared, at a selected center frequency above 2,000 MHz.  The antenna uses a folded planar dipole section having two separated oppositely disposed U-shape elements, each of said elements having a pair of ends.    A capacitor is series-coupled between two of the oppositely disposed ends of the elements, and a diode having a high impedance at the selected center frequency is series-coupled between the other two oppositely disposed ends of the U-shape elements.  A metallic backplane is mounted parallel to the planar folded dipole section and spaced from the dipole section a predetermined distance selected to reduce the antenna impedance.  The impedance of the diode, the shape of the folded planar diode section and the predetermined amount of spacing of the backplane from the planar folded dipole section are all selected to increase the d.c. power output of the antenna.

Abstract: ABSTRACT OF THE DISCLOSURE      An automatic laminator for laminating film on a board includes a control unit, input and output roller tables, and a control cabinet.  The control unit includes a tacking system, film supply rolls, takeup rolls, lamination rolls, a cutting system and a vacuum system.  The control unit features holding the board stationary between the completion of the tacking operation and the beginning of the lamination operation and the starting the lamination at substantially the same position where the tacking has been effected, thus improving the efficiency of operation and enabling a reduction in the time, pressure, and temperature required for the successful performance of tacking. This together with a simple and effective cutting system involving a cutting blade that moves only a few millimeters and cuts the film "on the fly" enables an increase in the rate at which the boards may be laminated.  Single side lamination of very thin boards is also made possible.      The input and output roller tables, the lamination rolls and all the machines are adjustable in height.  The input table is fitted with a centering device and with a gripping system for feeding the panels to the lamination rolls.  The output table carries a temperature sensor to measure the temperature of the panels and photocells to detect jamming of the boards. The control cabinet houses an electronic control and video display unit with keyboard.

Abstract: Abstract A virtually transparent magnetic layer is included as an additional layer in a color negative film.  Information exchange between various users of the film-such as (for example) the film manufacturer, the camera user, the dealer and photofinisher-is carried via plural longitudinal magnetic tracks on the film that begin and end in individual frames.  Each track is dedicated to the writing and reading of a predetermined set of parameters related to the corresponding frame.  All data is recorded as N-bit character where N is preferably six.  Each track is preceded by certain six-bit character called an ID sentinel.  On-film magnetic data recording by the film manufacturer uses an ID sentinel different from that employed in the camera.  The camera automatically prevents exposure of any frame bearing a camera ID sentinel, thus providing protection from double exposures.

The hot, inert solids of the fluidized bed are circulated by a regulated rate from the furnace (2) to a simple dryer (11) incorporated into the fuel feed line (7) to the boiler (1), whereby the fuel is dried and steam is generated. By virtue of controlled bed solids recirculation, a constant temperature of the dryer (11) can be maintained, thus permitting the omission of all heat transfer surfaces from the dryer (11). The nearly clean steam released from the drying process is routed from the dryer (11) to useful applications. (FIG.
