Title: Transit car door system and operation
Inventor: TEMPLETON FREDERICK E
IPC: B61D19/02
Filed: 1990-04-05
Abstract: 2030544 9012186 PCTABS00002 A computer assisted transit car door operating system for augmented automation of transit car door panel (72, 74) operation while providing safety provisions to restrain rail movement unless all passage doorways are closed. A programmable logic controller (180) generates a sequence initiating (opening or closing) signal for a door panel (72, 74), or a manual input signal can be introduced for such prupose. The controller (180) receives signals from a panel position sensor (84, 85) and a panel movement sensor (88, 90) to evaluate door panel status and generate status indication and panel movement signals. Automated control of door panel movement is selectively directed to a doorway, or doorways, at which an opening or closing problem is being encountered; that is, the exclusion of door panel movement signals to properly operated door panels (72, 74). An electrical cam device utilizes a radiant energy emitter (604) and detector (606) with a reversible-direction, coded attenuator (600), keyed to a reversible-direction DC  driving motor (76, 78) for a door panel (72, 74); modulating output of such radiant energy detector (606) indicates direction of movement and other data by coordination with the controller (180). An electrically controlled power switch (294) controls connection of a source of DC power to control direction of rotation of the reversible-rotation DC driving motor (76, 78) controlling opening and closing of a door panel (72, 74).

Title: Extended kraft cooking with white liquor added to wash circulation
Inventor: STROMBERG BERTIL
IPC: D21C9/16
Filed: 1991-03-07
Abstract: In the continuous kraft pulping of comminuted cellulosic fibrous material (e.g. wood chips) to produce paper pulp, viscosity for a given Kappa Number is significantly increased (e.g. at least about 20%) by adding kraft white liquor to the wash recirculation loop in a continuous digester.  Optimum results are obtained when kraft white liquor is also added to a recirculation loop at a central portion of the digester, so that the majority of the digester has countercurrent flow between white liquor and cellulosic material.  About 5-20% of the total white liquor  necessary to effect kraft cooking is introduced in the wash circulation, and about 10-20% is introduced into the central portion recirculation.  The temperature in the wash zone is maintained at about 140-175°C.

Patent CA-2041095-A1 (CA)
Title: Optical switch
Inventor: DORSEL ANDREAS
IPC: G02B6/34
Filed: 1991-04-24
Abstract: Abstract of the Disclosure The invention is directed to an optical switch for a sensor.  The optical switch conducts radiation emitted from a radiation source into a fiber leading to the sensor and conducts radiation returning from this fiber onto an optoelectric receiver.  The optical switch includes a filter having wavelength-dependent transmission and reflection characteristics as well as optical components for collimating or focusing.  The optical components together with the filter define a component unit in the form of an acute angle optical switch.  The optical switch also has a first beam splitter mounted downstream of the component for collimating the radiation emitted by the radiation source.  The beam splitter splits off a component of the radiation emitted by the radiation source as a reference beam and the reference beam is guided via deflecting prisms and spacers to a second beam splitter.  The second beam splitter geometrically superposes the reference beam onto the measurement beam returning from the fiber via the optical switch.  An air gap is provided ahead of the second beam splitter for accommodating a movable diaphragm therein which alternately interrupts the measurement beam or the reference beam.

Abstract: A vehicle is proposed, in particular a chassis of a bridge-underside inspection apparatus, having a frame (1) and road-vehicle wheels. In order to be able to quickly and simply convert such a vehicle into an operational chassis having increased stability, a pneumatically sprung axle unit (3) and, in front of and/or behind this pneumatically sprung axle unit, at least one unsprung auxiliary wheel (7, 8) are arranged on the frame (1). The axle unit (3) has a pneumatically actuated device (4, 5) which is connected to the spring-suspension arrangement and by means of which the frame (1) can be lowered from a top position in which the spring suspension is effective into a bottom position.      The auxiliary wheel (7, 8) is lifted from the roadway in the top position of the frame (1) during the road-transport operation and stands on the roadway in the bottom position of the frame (1) during working operation. Supporting rollers (6), which also serve as a slow drive, can be arranged above the wheels of the axle unit (3) (Fig. 1).

Inventor: BURKE EDWARD A
IPC: G09F17/00
Filed: 1991-07-22
Abstract: A kit for mounting a banner or flag on any pole.  The kit includes one or more horizontal arms (placed at the top, and optionally the bottom of the banner) to ensure that the banner is visible even in windless conditions. These arms are joined by a vertical strut.  L-brackets maintain the horizontal arms perpendicular to the vertical strut.  The banner may be fastened to the vertical strut by like means.  The L-brackets contain fixtures to fasten to grommets at the corners of the banner, to maintain the banner in a taut configuration, and further to fasten universally adaptable hoops, which hoops encircle the pole.  The banner frame is permitted to rotate about the vertical axis of the pole on the hoops.  A flexible rubberized shock cord is attached at its upper end to the pole by a band clamp or the like, and extends down to the upper L-bracket.  As the banner frame rotates, the shock cord is wound around the pole.  The length of the cord is selected so that 1.5 to 2 complete revolutions are possible.  When the wind dies, the elasticity of the shock cord returns the banner frame to the original position.          In the unlikely event that the wind "follows" the banner forcing it through the permitted 1.5 to 2 revolutions, the shock cord is designed to snap before dangerous wind loads are applied to the pole.

Patent CA-2052740-A1 (CA)
Inventor: STEWART ROBERT E
IPC: G01P15/13
Filed: 1991-10-03
Abstract: A force balanced instrument, such as an accelerometer, employs a pendulous mass having combined electrostatic pickoff and forcing plates on opposite sides thereof. The plates provide a constant attractive force in successive periods acting alternatively on opposing sides of the sensitive element. Force balance is achieved by controlling the duty cycle so that the difference in duration between each of the parts of a full cycle is a linear measure of acceleration. Voltage on each of the forcing plates is sensed independently immediately after each is charged with a fixed charging pulse which provides a fixed force level aver the duration of the part cycle.      The two successive voltage simples are stored, and the difference between them integrated to control the duty cycle of a pulse width modulator, which itself controls the duration of application of the alternately directed forces applied by the respective plates to the pendulous mass.
