Patent CA-2068504-A1 (CA)
Inventor: NAZMY MOHAMED
IPC: B21K3/04
Filed: 1992-05-08
Abstract: ABSTRACT OF THE DISCLOSURE         The turbine blade contains a casting having a blade leaf  (1),  blade foot  (2)  and,  if appropriate, blade cover strip (3) and composed of an alloy based on a dopant-containing gamma-titanium aluminide.     This turbine blade is to be distinguished by a long  lifetime,  when used  in  a  turbine  operated  at medium and high temperatures, and, at the same time, be capable of being produced in a simple way suitable for mass production. This is achieved in that, at least in parts of the blade leaf (1), the alloy is in the form of a material of coarse-grained structure and with a texture resulting in high tensile and creep strength and, at least in parts of the blade foot (2) and/or of the blade cover strip (3), provided if appropriate, is in the form of a material of fine-grained structure and with a ductility increased in relation to the material contained in the blade leaf (1).

Patent CA-2075293-A1 (CA)
Title: Optical multiplexer
Inventor: SUTTON PHILIP
IPC: H04B10/11
Filed: 1991-03-11
Abstract: Light from a laser (10) is divided by a beam splitter (12) to provide signal (15) and reference (14) channels. The signal channel light is expanded (11) to illuminate an acousto-optic (AO) device (13). This leads to a spatial distribution of Doppler shifted frequencies. This spatial distribution then illuminates a spatial light modulator (SLM) (19) such that a number of parallel and discrete optical channels (112) emerge. In a local area network (LAN) the optical signal channels are coupled into a single mode optical fibre (22) and then heterodyned to the reference laser light from a further optical fibre (23) in an optical coupler (25). In a receiver the modulated light is detected (32) and the detected signal connected to the transducer of an AO device (35). The AO  device (35) is illuminated by a receiver laser light (36) and the emerging modulated light is incident on a focal plane detector array (39) where each detector (310) then receives light corresponding to each of the transmitted channels (311). A secure free space communications system is possible by separate transmission of a delayed (43) unmodulated reference signal. The receiver is then arranged to include an identical delay (55) in the signal channels before coupling together the signal and reference channels (56) for modulating the AO cell (35). By this means the transmission delay lines (43) and the reference delay lines (55) must have delays which are equal within the coherence length of the source laser.

IPC: A23L5/10
Filed: 1992-08-11
Abstract: Apparatus and method for popping high yield popcorn using a bag having a substantially rectangular cross section as manufactured using a conventional bag machine.  A base supports the bag on edge with at least one joining panel being inclined such as, for example, at 45.  Whether the bag is initially unfolded or unfolds as a result of internal pressure caused by some kernels popping, a horizontal elongated V-shaped trough is formed as the lower-most region of the bag due to the supporting orientation of the base.          Kernels form in a clump in the nadir of the trough thereby enhancing the yield of the popping, and kernels disturbed from the clump by popping kernels are directed back to the clump by the inclined walls of the bag.

Patent CA-2088780-A1 (CA)
Title: Encoding system
Inventor: DALE JAMES
IPC: G11B20/00
Filed: 1990-09-14
Abstract: The method of encoding a given recorded signal made up of a host of different frequencies comprises modifying the recorded signal to selectively alter in a known manner a portion of the recorded signal to produce a machine recognizable start code which is generally unperceptible to human recognition when the recorded signal is played in its intended manner. The signal is scanned and immediately after the start code, an identity code is generated based on the particular signal characteristics which collectively are unique to the recorded signal and by means of which the recorded signal can be identified. A recorded signal which has been encoded in accordance with this method has a start code which can be machine recognized during playing of the recorded signal. This recognized start code locates a portion of the signal used to identify the same. Apparatus for carrying out this particular method, both in encoding of the recorded signal and scanning of signals which have been encoded, form part of the present invention. This invention is particularly useful for monitoring of broadcast signals having included therein material covered by copyright.

Title: Steel cable eyelet construction for a looped steel cable end
Inventor: POPP XAVER
IPC: E02D5/74
Filed: 1993-02-10
Abstract: A steel cable eyelet construction for a looped steel cable end is protected against corrosion by a tubular member of synthetic material that extends all the way around the loop and partially into the ground when the steel cable end is formed as an anchor that is cemented into the ground. The synthetic material tubular member in turn is protected against mechanical wear and tear by a tubular metal jacket such as a stainless steel jacket. This construction is especially suitable for anchors that are used to secure protection nettings against falling rocks and avalanches. Providing the corrosion protection and the mechanical wear and tear resistance by different elements assures a prolonged serviceability of such steel cable eyelets forming anchors cemented into the ground.

Filed: 1993-03-22
Abstract: 57,158 ABSTRACT OF THE DISCLOSURE A simplified,  readily removable  air gap baffle ring for a gas  cooled dynamoelectric  machine, such  as a turbine  generator.     The   baffle  ring  comprises  two composite rings with  a  seal material  sandwiched there-between and bonded into a single ring structure.  The seal ring attaches to  finger  plate  extensions  which  are an integral part  of the generator core, and forms an air gap seal between the rotor retaining ring and end wedges which extend from  the stator  coil slots.   The  air gap baffle assembly of the present  invention  effectively  seals the high pressure  zone of  the exciter  end of the generator, from  the  lower  pressure  radial  air  gap  zone located between the  generator rotor  and stator, to thereby force cooling gas to flow into the rotor and stator.

Title: Method of disposing of drilling wastes
Inventor: JENNINGS ALFRED ROY JR
IPC: E21B41/00
Filed: 1991-09-26
Abstract: A method for disposing of drilling wastes where an aqueous saline solution is used to disperse a drilling fluid or mud. The saline solution containing the dispersed drilling fluid or mud is injected into a disposal well or high permeability oil depleted zone.  An interval of the formation adjacent to the disposal well is hydraulically fractured so as to allow continued injection of the solution containing the drilling fluid or mud at substantially low pressures. Hydraulic fracturing is used to re-establish communication with a disposal zone whenever a "skin" builds up due to filtration of the solids from the injected drilling fluids or muds.

Title: Polymer-dispersed liquid crystal device having an ultraviolet-polymerizable matrix and a variable optical transmission and a method for preparing the same
Inventor: MILLER STEPHEN A
IPC: C09K19/54
Filed: 1992-01-10
Abstract: A polymer-dispersed liquid crystal device comprises a multiplicity of droplets of a birefringent, functionally nematic liquid crystal material dispersed in a matrix comprising the reaction product of ultraviolet radiation polymerizable materials. The device specularly transmits incident light as a function of the magnitude of an electric field applied across the device. The difference between a first applied voltage corresponding to a first percentage of the total incident light transmitted by the device as a specular light and a second applied voltage corresponding to a second percentage of the total incident light transmitted by the device as specular light is greater than or equal to 15 volts. As a result, a polymer-dispersed liquid crystal device according to the invention displays a variable grey scale which has a uniform optical transmission. A method for preparing a PDLC device in general is also disclosed.
