Patent CA-2085426-A1 (CA)
Title: Synchronized resetting of coding devices
Inventor: BOLY JEAN P
IPC: H04J13/00
Filed: 1992-12-15
Abstract: In a system for de-/encoding data using (de)coding devices at either end of a transmission channel, the data sometimes comprise additional synchronisation information which is used to reduce the effect of faults in the transmission channel. If this synchronisation information is not already present, it is impossible in certain cases to add such information. The invention provides a system which, regardless of the presence of additional synchronisation information, is able to reduce the effect of faults. For this purpose each (de)coding device is provided with means for comparing sequences of encoded data with at least one predetermined code word and for setting the associated coding device to a reset state in the event of equality. Because the predetermined code word repeats statistically in the encoded data, a fault adversely affects the decoding for not more than one time interval.

Inventor: DION FERNAND
IPC: F16F1/48
Filed: 1993-01-07
Abstract: A  suspension system for  compensating road-borne loads applied selectively  to one end  of a vehicle wheeled  axle.  The suspension  system  includes a  pair  of  elongated rigid  tubes, extending longitudinally  over opposite sides of  the wheel axle, and supported  thereover by corresponding upright  posts anchored to the  intermediate section  of the wheel  axle.  Each  post and associated tube  have a number of  lateral interdigitating hollow ears, wherein the tube and post are pivotally interconnected by a lengthwise  rubber shaft.  A  bottom frame beam  from the vehicle body extends laterally outwardly  of each corresponding tube, and includes a plurality of ears interdigitating with additional ears from the proximate tube for through  engagement by another rubber shaft,  for pivotally interconnecting the  beam to the  tube.  In normal condition, each beam ear rubber shaft is downwardly offset relative  to the post ear rubber shaft.  Thus, as the axle on one side  of the vehicle is  lifted following a  road-borne load, the vehicle  beam on  that side  will sink  as well as  move inwardly toward  the  intermediate   portion  of  the  axle,  due  to  the deformation of the rubber shafts, whereas the vehicle beam on the opposite side will raise  as well as move outwardly away from the intermediate axle portion.

Abstract: An actuator and valve assembly for an electronically-controlled injector is disclosed which comprises an electrically-energizable actuator assembly and a device for communicating, collecting and draining damping fluid with respect to at least one cavity of the actuator assembly. If too much damping fluid remains in the actuator assembly after engine shutdown, that damping fluid may cool off and cause slow response of the actuator and valve assembly during cold engine starting. The end result is that quick starting and/or operation of the engine may be hindered, particularly under cold engine conditions. The communicating, collecting and draining means permits at least a portion of the hot damping fluid to automatically drain from the cavity after the engine has been shutdown.

Abstract: Abstract of the Disclosure APPARATUS AND METHOD FOR MARKING A RUBBER ARTICLE WITH     A MESSAGE READABLE BY A LIGHT SCANNING DEVICE      An apparatus and method for supplying a graphic label that is readable with a light scanning device with such label placed on a rubber article.  The graphic bar code label is optically interpreted with a bar code reader.     Thus, the cured substrate with the label with the graphic message is produced by using thermal transfer techniques.  For this purpose, the ribbon in contact with the substrate passes by a print head and the ink can be selectively heated with this operation being synchronized by computer operation.  When the ribbon is stripped away, the ink is left where heating occurred on the substrate material.  The printed substrate exits and is cut to produce labels of desired length.  The label is placed on a cured or curable article and the label and substrate are subjected to curing conditions to effect transfer of the label to the cured substrate which may now contain the message in solely, alphanumeric, bar codes, human readable characters, and logos or mixtures of them. The bar code message is normally printed as a series of vertical bars and spaces of varying widths to supply the message in readable form with the light reflected from the series of varying width bars and spaces.

Title: Ammeline-melamine-formaldehyde resins (amfr) and method of preparation
Inventor: CREWS GEORGE M
IPC: C08G12/32
Filed: 1993-08-23
Abstract: Ammeline-melamine-formaldehyde resins (AMFR) containing from 5-10% ammeline were synthesized by the polymerization of the sodium salt of ammeline, which must be made in advance, melamine and formaldehyde in basic medium (pH = 9.2 - 10.0). In this copolymerization, it is possible to make uniform random AMFR resins with any mole ratio of ammeline salt to melamine.      Preferably the AMFR resin will contain from 5 - 10% ammeline.      As an "ionomer" or a "polyelectrolyte", both the solid and solution properties of these resins (such as melting temperature, solubility, solution stability, etc.) depended directly on the mole ratio of ammeline to melamine and formaldehyde and/or on the pH value of the medium in which the AMFR resin was present. The pH value controlled the ammeline rings/ammeline's salt groups and also the ratio of unprotonated to protonated amino groups on both the melamine and ammeline rings. These polymers have different solubilities, cloud points and solution lifetimes (which depend on pH) than melamine-formaldehyde resins. AMFR systems containing from 5 - 10% ammeline are more flexible than MFR resins and exhibit different adhesion properties than MFR resins.
