Patent CA-2030849-A1 (CA)
Inventor: LUBINSKI RONALD
IPC: E04G5/08
Filed: 1990-11-26
Abstract: A plank for use on a scaffold. The principal component is a hollow integral aluminum extrusion with an elongate rectangular shape transverse to its length. The extrusion has a top wall, a pair of spaced-apart opposing sidewalls extending downwardly from the top wall, and a longitudinal locking structure located between the sidewalls. A complementary fastening assembly cooperates with the locking structure to secure the extrusion to a horizontal cross-member of the scaffold. Sheet material containing mineral particulates is adhered to the upper surface of the extrusion to provide a non-slip walking surface. After use in an environment containing dangerous contaminants, such as radioactive materials, the sheet material may be stripped for disposal and the extrusion cleaned with an appropriate solvent before re-application of fresh sheet material.

Title: Updating link state information networks
Inventor: PERLMAN RADIA J
IPC: H04L12/56
Filed: 1991-01-29
Abstract: Abstract of the Disclosure Methods and apparatus for sending link state information through a network of nodes interconnected by links.  Link state packets (LSPs) are fragmented, and the fragments are sent individually through the network.  The network routers may update their link state databases and perform routing without having to receive and reassemble all of the fragments.  When the state of a link changes, only an amended version of the fragment affected by the change is transmitted.  In another aspect, the invention features methods and apparatus for transmitting LSP sequence number information through the network.  First, the link state packets being stored by a node are ordered alphabetically according to their source node.  Next, a range of this order is selected and placed in a summary packet indicating the boundaries of the selected range and, for each link state packet in the selected range, the source and sequence number of the stored link state packet.

IPC: H04B1/38
Filed: 1991-03-06
Abstract: A mobile radio programmed to analyze idle channel assignments issued by a repeater station and select different channels, if appropriate, which are especially adapted for communicating with other communication facilities, such as a telephone interconnect. Programmed into the mobile radio with each communication channel is an indication of whether or not such channel can be utilized to communicate with the other communication facility.  If communications are desired with the other communication facility, and if the present idle channel assigned by the repeater station does not permit such communication, then a processor in the mobile radio consults a data list of appropriate channels, selects one such channel, and then establishes communications to the other communication facility on such channel.

Title: Method for operating an asynchronous packet bus for transmission of asynchronous and isochronous information
Inventor: ROPOSH RONALD C
IPC: H04L12/56
Filed: 1992-05-15
Abstract: A facility is provided for operating an asynchronous packet transmit bus such that isochronous information packets may be transmitted from a source to a destination with a fixed, constant delay. The fixed, constant delay is achieved by employing a bandwidth management bus and assigning to port modules which contend for access to the transmit bus respective levels of priority, in which the highest level of priority is associated with isochronous information and in which lower levels of priority are associated with other types of information, such asasynchronous information.  In addition,  each port module which transmits isochronous information is assigned at least one time slot of each frame of time slots. In this way, a port module that needs to transmit isochronous information is granted access to the transmit bus during its assigned time slot if the module asserts such highest level of priority in response to its address being transmitted over the bandwidth management bus. If the module fails to assert such priority, then the time slot is marked for open contention, thereby allowing the other port modules to contend for access to the transmit bus during that time slot.

Filed: 1991-09-30
Abstract: ABSTRACT OF THE DISCLOSURE A   propulsion   system  for  using  a  pair  of electric induction motors to power  a pair  of  vehicle drive  wheels.   The  motors  are  driven  by  pulses of electric current from a common dc bus.   The  inductance of  stator  windings  cause electric curent to power the motors during the time  between  pulses  so  power  from the  dc  bus  is  low.  When a vehicle is making a tight turn, an inside motor provides an  electric  current  to the  dc  bus  to  supply  additional power to an outside motor.   Speed  and   steeirng   signals   operate   the electric  motors  and  control speed of an engine and an alternator which supply power to the dc bus.

Title: Fish scope
Inventor: BILLEY KEN
IPC: G02B23/22
Filed: 1992-12-29
Abstract: Schedule 2 Abstract The "Fish Scope", derived from the periscope, is intended for use by sport fishermen who wish to observe fish activity beneath the surface of the water or beneath a cover of ice. Fishermen must rely on blind luck or expensive, electronic devices to identify the best location to drop a hook in hopes of catching a fish. Ice fishermen in particular rely on experience and luck to locate schools of fish, drilling countless holes in the ice in an attempt to identify the lucky spot. The "Fish Scope" will permit visual scanning of the underwater areas and improve the chance of dropping a hook close to where fish are congregating. In addition this invention can be used by anyone needing to observe areas or objects in areas which cannot be accessed directly for safety reasons or because  of restricted access.

Abstract: In construction of a handle less tool chuck in which clamping torque is transmitted from a manually rotatable operation sleeve on a chuck body to tool clamping jaws in the chuck body via a power transmission unit including a cycloidal gear arrangement, an elastic impulsion sleeve is inserted between the operation sleeve and the chuck body so that elastic compressive deformation of the impulsion sleeve at forced rotation of the operation sleeve causes impulsive meshing engagement in the cycloidal gear arrangement to pose impulsive clamping force on a tool clamped by the jaws.      Resultant clamping forces is twice or more as large as that provided by the conventional cycloidal gear arrangement only.
