Patent CA-2069437-A1 (CA)
Title: Process for control of fruit ripening in plants
Inventor: GRIERSON DONALD
IPC: C12N15/82
Filed: 1990-11-26
Abstract: The ripening of fruit is retarded in inhibiting production of one or more enzymes selected from pectinesterase, galactosidase, glucanase, xylanase, cellulase and polygalacturonase involved in the ripening process. Inhibition is effected by introducing into the genome of a fruit-producing plant by genetic transformation a recombinant DNA which codes for only part of one or more of the said fruit-ripening enzymes.

Title: Casing for projection television receiver and screen mounting method
Inventor: GOTOU KATUMI
IPC: H04N5/74
Filed: 1992-06-29
Abstract: The present invention is directed to a method for installing a screen to a projection television receiver that uses a transmission-type screen such that the screen can be easily installed to and removed from the projection television receiver when multiple projection television receivers are combined to form a single large-scale multiple display system in which the receivers are stacked vertically and horizontally in an M x N rectangular configuration.  Screen holding brackets installed in the cabinet body and screen clamping frames are used to secure the screen in place by inserting the screen clamping frames into a slight gap formed between the cabinet body and the screen holding brackets.  Even when the screen clamping frames are inserted into the gap and adjusted to secure the screen, all movement of the clamping frames occurs within the dimensions of the cabinet body, thus making it easy to remove and install the screen even when multiple projection television receivers are combined in a single large-scale display system.

Filed: 1991-02-21
Abstract: Microsphere (10) wet cake, is mixed with a surface barrier coating (14) effective to prevent agglomeration and surface bonding of the microspheres. Water is removed by drying at high shear with continuous mixing. In a subsequent step, by controll-ing the application of heat to balance temperature and coupling this with low shear mixing, blowing agent (12) will produce con-trolled expansion of the microspheres. The surface barrier coating (14) in the present invention is any one of a wide diversity of materials which meet the requirements of the intended function, i.e., to prevent the agglomeration of the microspheres during the process. Suitable materials (14) include by way of example, dry inorganic pigments or filler materials, and the like, and related inorganic materials.

Title: Plastics cartridge case and plastics cartridge case-belt magazine
Inventor: JENA HANS
IPC: B25C1/16
Filed: 1992-07-22
Abstract: Abstract A plastics cartridge case and plastics cartridge case-belt magazine A cartridge case (23) is composed of a plastics casing body (16) and a plastics cover (20). Accommodated in the casing body (16) is a first receiving chamber (46) for accommodating an ignition charge (52) and a second receiving chamber (48) for accommodating a propellent charge composition (60).  A flexible plastics ignition pin (30) connected to the cover (20) is plunged into the first receiving chamber (46).  When there is pressure action caused on the rear end (40) of the ignition pin (30) by a striker (66), the pin is moved forward into the first receiving chamber (46), its pointed front striking end (32) acting on the ignition charge (52) in order to ignite this.  The ignition charge (52) is accommodated the shape of a funnel in a conical indentation (53) of the first receiving chamber (46).  The ignition pin-striking end (32) plunging into the ignition charge (52) generates friction in the ignition charge material and thereby frictional heat in this.  As a result of this "stab initiation principal", it is possible to obtain a reliable ignition of the ignition charge (52) despite use of plastics as the material for the casing body (16) and the ignition pin (30), this material being substantially softer than metal. (Figure 8).

Title: Low distortion laser system for am fiber optic communication
Inventor: GLAAB JOSEPH B
IPC: H04B10/54
Filed: 1992-08-06
Abstract: An information signal modulates a first optical carrier. The information signal is inverted to modulate a second optical carrier. The modulated first and second optical carriers are multiplexed into a single optical signal for communication over an optical fiber path. At a receiver, the optical signal is demultiplexed to recover the information signal and the inverted information signal. The recovered signals are combined to provide the information signal in the electrical domain with reduced distortion. A dual-detector balanced optical diode pair can be used to combine the recovered information and inverted information signals and provide an analog RF output. The apparatus is particularly suitable for the transmission of AM-VSB television signals.

Abstract: Fly ash generated from incineration of municipal solid waste (MSW) when placed in landfills under mild acid conditions can leach lead and cadmium. A process for stabilizing heavy metals in this fly ash is presented which involves calcining in the presence of an oxygen containing gas stream at a temperature greater than about 375 DEG C and substantially less than about 800 DEG C for times from about 170 seconds up to about 5 hours fly ash which has been subjected to lime scrubbing for acid gas removal. Such treated MSW fly ash will give leachates containing heavy metal concentrations less than the EPA regulatory limit. <IMAGE>

Patent CA-2082359-A1 (CA)
Inventor: BACKSTRAND JON E
IPC: B66C13/30
Filed: 1992-11-06
Abstract: The inventive method and machine are improvements in aspects of a material handling machine (such as an overhead travelling crane) having an electrically-powered traverse drive, e.g., a bridge drive.  Such machine has (a) regenerative motor braking and (b) a manually-applied hydraulic brake, both for retarding the machine.  The invention prevents the bridge drive motor from "driving through the brake" when the hydraulic brake is being applied to result in significant retarding torque.  When the hydraulic brake is pedal-applied, an electrical contact closes at a predetermined hydraulic pressure and other devices, relays and the like, are actuated to modify operation of the controller and prevent "motoring" simultaneous with hydraulic braking.   Regenerative braking is likely to be set for a retardation rate less than results from application of the hydraulic brake. The invention prevents the drive motor and hydraulic braking system from "fighting."  With the invention, the motor control unit is disabled at some predetermined pressure in the brake hydraulic line.  Thereafter, the machine is retarded solely by application of the manually-operated brake until the machine reaches a very slow speed.

In a preferred embodiment,  a maximum value of .DELTA.T is also provided, which, if exceeded by the actual .DELTA.T, indicates a restricted air flow in the cargo space.
