Patent CA-2028716-A1 (CA)
Title: Methods and apparatus for optical product inspection
Inventor: CASASENT DAVID P
IPC: G06V10/88
Filed: 1990-10-29
Abstract: Abstract of the Disclosure Lines of text (e.g., printing on a product) are verified by forming a one-dimensional image of each line substantially parallel to its length.  This one-dimensional image information is compared to corresponding information for the intended lines of text.  This comparison is preferably done using acousto-optic correlator systems.  Space and frequency multiplexing may be used to allow parallel processing of several lines of text and/or to allow comparisons with multiple references to be made simultaneously. The invention may be used to determine the acceptability of products based on the correctness of the text image, and to reject products on which the correct text does not appear.

Abstract: A four wheeled vehicle supporting a ground probing radar antenna 52 has an aluminium alloy square plate 10 and four wheel mountings 14 supported by four pairs of equal-length arms 18,20.  The arms as seen in plan are arranged in a square. One arm 18 in any pair extends lengthwise of the vehicle from an anchorage 30 on the vehicle  to a mounting 14 and the other 20 extends transversely of the vehicle from an anchorage 32 on the vehicle to the mounting 14.  Each mounting carries a buffer 36 which on upward movement presses against one of two spring arms 38 carried by mountings 42, one arm being locked in its mounting.  The vehicle has an overcover 70 and an undercover 72.  In a modification pneumatic spring units instead of arms 38 control vertical wheel motion.

Abstract: Abstract of the Disclosure A method of connecting a waveguide substrate made of electro-optical crystal and an optical fiber by means of a bonding agent of the ultraviolet light curing type is disclosed.  According to the method, first, a reflection preventing film with an ultraviolet light intercepting function of passing therethrough light of a wavelength to be transmitted by way of the optical fiber but intercepting ultraviolet rays of a wavelength with which a bonding agent is to cure is formed on an end face of a waveguide substrate.  Then, an end face of the optical fiber is closely contacted with the reflection preventing film with the bonding agent applied to the end face of the optical fiber, and ultraviolet rays are irradiated upon the end face of the waveguide substrate from the side on which the reflection preventing film is formed to cause the bonding agent to cure.  Also detailed layer structures of such reflection preventing film with an ultraviolet light preventing function are disclosed.

Title: Safety thermostat
Inventor: BOURGIN ALAIN
IPC: F16K31/68
Filed: 1990-09-07
Abstract: Immersed, fusible, safety valve(s) device substituting for the defective thermostat element in an engine or the like. The device is comprised of a predetermined temperature eutectic alloy fusible element (20), a valve closing antagonist spring (80), a safety holding spring (90), an extensible staple (70), a body (30), a function valve (40), a holding staple (60), a thermosensitive element (50), a pusher rod (51). To remedy the shearing efforts, the eutectic alloy is used for the weldings. In order to remedy the inconveniency of a temporary or permanent break-down, the extensible staple (70) reverses the closing device into an opening device, releases the stress and prestress elements, neutralizes the function of the thermosensitive element. The same applies when the safety device has been made by eutectic welding of the annular valve (40) to the thermosensitive element (50). This device, in these two embodiments, gives during normal and safety operation conditions a maximum flow indefinitely.

Abstract: ABSTRACT       An extension rod assembly for manually positioning a tool head in contact with a work surface comprises an extension rod, a pivotable tool head, and a control linkage for locking the tool head in a selected angular position relative to the extension rod.  The control linkage comprises an elongate connecting member which extends through the rod, a manually operable handle at the control end of the rod, and a clutch mechanism which is operated by the handle.  The clutch has a first position in which it is disengaged from the connecting member, and a second position in which it is frictionally engaged to the connecting member in order to exert a linearly-directed force on the connecting member so as to actuate a locking assembly which locks the tool head in position.  In the disengaged position, the clutch permits linear movement of the connecting member past the clutch and handle as tubular portions of the extension rod are telescoped to a desired length. In this manner, operation of the handle to select the disengaged position permits the operator.

Patent CA-2066229-A1 (CA)
Title: Data compression apparatus
Inventor: O'BRIEN JOHN T
IPC: H03M7/48
Filed: 1990-09-05
Abstract: The improved data compression system (100) concurrently processes both strings of repeated characters and textual substitution of input character strings. In this system (100), the performance of data compression techniques based on textual substitution are improved by the use of a compact representation for identifying instances in which a character in the input data stream is repeated. This is accomplished by nesting a run length encoding system (110) in the textual substitution system (111, 112, 120). This structure adds the recognition of runs of a repeated character before the processor performs the textual substitution data compression operation. A further performance improvement is obtained by expanding the alphabet of symbols stored in the compressor's dictionary (120) to include both the characters of the input data stream and repeat counts which indicate the repetion of a character. The handling of these repeat counts by the textual substitution based compression technique is no different than the handling of characters, or certain modifications are made in the handling of repeat counts.
