Patent CA-1071705-A (CA)
Title: Method of preparing porous active material for use in electrodes of secondary electrochemical cells
Inventor: VISSERS DONALD R
IPC: H01M4/62
Filed: 1976-12-20
Granted: 1980-02-12
Abstract: ABSTRACT OF THE DISCLOSURE    Particles of carbonaceous matrices containing embedded electrode active material are prepared for vibratory loading within a porous electrically conductive substrate.          In preparing the particles, active materials such as metal chalcogenides, solid alloys of alkali or alkaline earth metals along with other metals and their oxides in powdered or particulate form are blended with a thermo-setting resin and particles of a volatile to form a paste mixture.  The paste is heated to a temperature at which the volatile transforms into vapor to impart porosity at about the same time as the resin begins to cure into a rigid, solid structure.  The solid structure is then comminuted into porous, carbonaceous particles with the embedded active material.

Abstract: ABSTRACT OF THE DISCLOSURE               A solar energy collector of low cost and high thermal effeciency is disclosed having a heat trap pro-duced by zigzagging a thin strip of polyethylene terephtha-late between opposite sides of the trap while wrapping the strip about rows of dowels positioned at opposite sides of the frame of the solar collector.  A window of soda lime glass filters UV radiation to inhibit discolora-tion of the plastic heat trap walls.  An absorber plate having fluid pipes therein is positioned underneath the heat trap and a first layer of fiberglass, and a second layer of polyurethene foam are positioned below the absorber plate.  The fiberglass layer prevents over-heating of the polyurethane foam layer to in turn inhibit the formation of toxic fluids, which may condense upon the underside of the window to reduce the efficiency of the collector.  An automatic freeze protection system for the solar energy collector includes sensor means are provided within the collector to monitor the temperature of the water, and whenever it approaches the freezing point, the sensor will automatically actuate a valve means to rapidly drain the water from the collector.  When the temperature within the collector thereafter rises to a predetermined safe level, the sensor means will again automatically actute the valve means to refill the collector with fresh water to be heated.  The system provided thus avoids the need for anti-freeze or other freeze protection materials suggested by the prior art as well as isolated water loops, heat exchangers and other expensive safety equipment necessitated thereby.

Abstract: TELEVISION SYNCHRONIZING APPARATUS            Abstract of the Disclosure Television synchronizer apparatus includes a coherent memory with preassigned fixed burst phasing of 0° or 180° for each line store of color video image information.          The incoming synchronizing components including burst are discarded on the premise that they are well-known repetitive functions.  The incoming color video image information is read into the memory coherent with the preassigned burst phasing, thereby significantly reducing the memory storage capacity normally utilized to store sync and burst information.

Abstract: "METHOD AND APPARATUS FOR CLOSING      AND SEALING CONTAINERS"                   Abstract of the Disclosure An apparatus is described for handling a continuous, stuffed, flexible casing and especially stuffed with explosives material.  The apparatus includes pairs of split necking plates on either side of a casing path adapted for opposed reciprocal movement for engaging the casing in the path and necking the casing.  The necking plates are mounted by a parallelogram linkage suspended from an overhead frame, and linkage means are provided for simultaneously moving the necking plates through said parallelogram linkage to neck the casing.  Each pair of necking plates is adapted to move apart in a direction parallel to the axis of the path of the casing such that when the casing is necked by the necking plates, the neck so formed on the casing can be elongated by moving the plates apart.  Magazine means are provided for advancing clips overhead of the casing, and a reciprocating plunger removes the clips from the magazine and arranges them on the neck portion of the casing between the necking plates as they are split apart.          Die means are pivoted from the overhead frame and adapted for movement to and from a position between the split-apart necking plates below and adjacent the necked portion of the casing for receiving and forming the clips.  Cutting means are pivotally mounted to the overhead frame for movement between the split-apart necking plates to cut the casing in the vicinity of the clips.

Abstract: ABSTRACT OF THE DISCLOSURE     The invention relates to a novel structure for a skate boot made of a synthetic material.  In order to provide flexibility in the ankle area of such boots, the boots are con-structed of an upper shell and a lower shell.  The lower shell consists of the heel, toe and sole portions of the boot, and the upper shell is movably attached to the lower shell and placed so that it surrounds the ankle of a wearer.  In prior art arrange-ments, the upper shell is pivoted by rivets at two points on either side of the boot, and this arrangement is inconvenient in that it is not removable because of its use of rivets.  In accordance with the present invention, the upper shell is re-movably attached to the lower shell by a button and buttonhole arrangement.  In one embodiment, it is so connected at the rear of the boot.  The novel boot also contains a reinforcing layer at the sole and toe portions of the boot.

Abstract: ABSTRACT     In a machine for harvesting trees, it is known to have a vehicle carrying a woodbunk and a boom mounted felling head which axially advances a grasped tree trunk for delimbing and bucking. Moreover, it is known to have the boom and felling head articulated so that a tree can be advanced over the woodbunk and upon bucking will fall into the woodbunk. This invention contemplates an improved configuration of components in which a side unloading woodbunk is mounted at the front of the vehicle with the felling boon mounted directly in front of the woodbunk. This permits a particularly short, singly articulated boom to fulfill the felling and woodbunk loading functions.

Abstract: PROCESS FOR PRODUCING UNIFORM NOZZLE ORIFICES  IN SILICON WAFERS          Abstract Nozzle plates for ink jet recording are produced by etching through silicon and like monocrystalline material wafers which frequently are non-uniform in thickness.  The "100" plane surfaces of the wafers are coated with etchant masking material after which a nozzle array pattern is defined on the obverse surface and a similar, but larger and less exacting, aperture array of the same pattern is defined on the reverse surface. The silicon wafer as thus exposed is anisotropically etched from the reverse substantially through to the obverse and thereafter etched completely through the wafer from the obverse by the same anisotropic process.  The lateral walls of the nozzles are substantially in the "111" plane of the wafers.  The masking material is then stripped from the wafer.

Abstract: ABSTRACT OF THE DISCLOSURE           An improved solid state electronic dimmer circuit for controlling the intensity of large electric lamps, such as theater and television lamps, in response to a low power DC control signal.  The transfer charac-teristic of the circuit is determined by the properties of a generated precision waveform having a predetermined shape and amplitude and a fixed phase relationship to the power line voltage which, in conjunction with the DC control signal, determines the effective voltage at the output of a dimmer unit.  The same precision waveform may be used to control a plurality of dimmer channels, thereby making possible precise matching of performance of all commonly controlled channels, and effecting significant savings in the cost of manufacture.
