Patent CA-2037600-A1 (CA)
Inventor: HARDIN PAUL W JR
IPC: E01F15/00
Filed: 1991-03-06
Abstract: The disclosure relates to a traffic barrier gate (15) for controlling the flow of vehicles through a barrier, such as a concrete median wall between opposing traffic lanes of a controlled access highway. In one embodiment the gate comprises hinged sidewall panels (21a, 21b) connected to a support member (26) which is moved vertically on command and which, when moved, causes the sidewall panels to collapse and spread out thereby forming a ramp for the passage of vehicles through the wall barrier. In a second embodiment, the gate (15) revolves 180 DEG , upon command, and then retracts into a well (66) in the ground thereby forming the traffic ramp. <IMAGE>   <IMAGE>

Patent CA-2043959-A1 (CA)
Inventor: GIBBONS GERARD P
IPC: G01R31/00
Filed: 1991-06-05
Abstract: A battery monitoring method and apparatus are used for monitoring the charge level of a rechargeable electric storage battery, for example a lead acid battery. The counter-voltage of the battery is monitored by continuously monitoring the actual terminal voltage of the battery. When the battery is fully charged, the monitor provides a "DO NOT CHARGE" signal, for example a green light. When the charge level has dropped to a point that there may be some value in recharging the battery, the "DO NOT CHARGE" signal is replaced with an "OK TO CHARGE" signal, for example a yellow light. When the battery has discharged to the point where the battery must be recharged in order to avoid damage, the "OK TO CHARGE" signal is replaced with a "MUST CHARGE" signal, for example a red light. Audible signals may accompany the "OK TO CHARGE" and "MUST CHARGE" signals. The monitor is self-testing when turned on. It automatically recognizes the charge level of a battery to which it is connected. When used in association with, for example, a lift truck, the monitor may include a lift lock-out function that is engaged in response to the battery being discharged to the "MUST CHARGE" level.

Abstract: ABSTRACT OF THE DISCLOSURE    Several improvements in tape applying machines are described.  A mounting mechanism for mounting a tape head in an upper bridge structure of the tape applying machine includes J-configured slots that are engaged by pin members extending from the taping head.  Another improvement includes a mechanism for retaining shafts of freely rotatable rollers in a conveyor assembly that is attachable to the carriage of a tape applying machine.  The mechanism includes a retaining member that is fixedly attached to a frame member of the conveyor and has a tab portion that extends into a slot in the shaft of the roller thereby securing the shaft in a non-rotatable state.  Another improvement includes a connecting mechanism for connecting the conveyor to the carriage of the tape applying machine. The connecting mechanism includes first and second pin means laterally spaced apart and extending outwardly from a panel face of the carriage.  Each pin means includes a shaft portion and a nodule that extend into respective key holes in the frame members of the conveyor.  The key holes include a first aperture portion sufficiently large in diameter to accept the nodule of the pin means and a second aperture, less in diameter than the nodule and sufficiently large to accept the shaft of the pin means.  Another improvement includes a tape supply roll holder for holding a supply roll of tape for a lower taping head that is disposed on the carriage of the tape applying machine.  The tape supply roll holder holds the roll of tape at a position that is viewable by the operator of the machine. A mechanical stop for retaining a pneumatically operable bridge structure in a raised position in the tape applying machine when the pneumatic circuit is in non-operable state is also described.  Another improvement includes an emergency stop switch means disposed on an upper surface of the bridge structure such that it is accessible from either side of the machine.  A pair of spaced apart compression rollers are positioned to engage upper opposing portions of a box traveling across the carriage so that edge portions of upper flap members of the box are positioned in substantially parallel relationship to each other for taping by the upper taping head.

Abstract: A routing system for a linear add-drop multiplexer (ADM) having two drop switches, operates to establish paths according to a relatively simple process and to establish paths according to a program that is relatively small in scale and in-expensive to develop.  The routing system includes a first selection switch for selecting one of several channels connected to a first transmission line and for outputting a signal transmitted through the selected channel.  A first selector selectively outputs and inhibits the signal transmitted from the first selection switch.  The first selection switch and the first selector are provided in one of the drop switches.  A second selection switch selects one of several channels connected to a second transmission line and outputs a signal transmitted through the selected channel.  A second selector inhibits the signal transmitted from the second selection switch when the first selector outputs the signal, and outputs the signal when the first selector inhibits the signal.  The second selection switch and the second selector are provided in the other of the drop switches.          The signals are transmitted from the first and second selectors to a transmitter/receiver for lower signal levels.  The routing system of the invention operates to establish paths in a relatively simple, inexpensive manner.

Abstract: An apparatus for testing an anti-lock brake system has rolls and device for detecting rotational changes of the rolls.  The test is performed by running a vehicle having mounted thereon the anti-lock brake system while wheels of the vehicle are placed on the rolls, actuating the anti-lock brake system when a predetermined speed has been attained, and judging operating conditions of the anti-lock brake system from rotational changes of the rolls at the time of braking.  In the apparatus, the friction coefficient of each of the rolls is set to such a value that a frictional force to act between each of the rolls and each of the wheels at the time of braking exceeds an inertia force of each of the rolls.  Also the inertia weight of each of the rolls is set to such a value that deceleration of each of the wheels at the time of braking can be increased to a predetermined level which is required to start an anti-lock control and that each of the wheels does not stop before the completion of a first braking pressure reduction by the anti-lock control.
