Patent CA-2071776-A1 (CA)
Title: Collapsible cheese container
Inventor: WHEELER WILLIAM E
IPC: A01J25/13
Filed: 1992-06-22
Abstract: A collapsible container far making and transporting cheese is made with four interlocking wall panels. Each of the panels is molded from a resin material with ribbed construction and with locking elements for engaging adjacent panels. The lacking elements provide mechanical interlocks against relative movements of the panels along two axes that extend normal to the panels and frictional interlocks against relative movements of the panels along a third axis that extends normal to the other two axes. The mechanical interlocks also transmit a preload torque that resists angular diverging movements between the panels about the third axis. The preload torque bows the panels toward an interior space of the container before the container is filled with cheese.

Title: Gemstone holding apparatus
Inventor: TOLKOWSKY GABRIEL S
IPC: B24B55/02
Filed: 1992-07-02
Abstract: ABSTRACT            During polishing of a gemstone (30, 100, 200), a coolant is passed in heat exchange relationship with the gemstone to remove heat. This reduces the risk of temperature degradation of the gemstone. In practice, this can be achieved by passing a fluent coolant through a coolant chamber (34, 124, 214) which forms part of the apparatus that is used to hold the gemstone during polishing and which is in heat exchange relationship with the gemstone held by the apparatus.
Patent CA-2078206-A1 (CA)
Inventor: COOK PAUL P
IPC: D02J1/22
Filed: 1990-03-29
Abstract: This invention provides methods by which any staple fiber or continuous filament can be stretch processed such that the fiber's internal molecular structure is oriented along the fiber strand axis. With only the simple continuous and simultaneous ap-plication of a single dynamic stretching stress, and a single dynamic twisting force, that is correct and precisely controlled relative to each other and to its input flow rate, every individual fiber is effectively and uniformly stretch processed. Such individual fib-er's net strength properties gain and desirable quality characteristics improvement as well as their continuous cross-sectional un-iformity are substantially enhanced for their greater utility. The methods of this invention can substantially improve the stretch processing uniformity of continuous filament fiber and hold its substantial original extruded evenness allowing multiple series treatments providing substantially improved stretch processing effectiveness and uniformity.

IPC: A01D34/62
Filed: 1992-12-03
Abstract: A mower cutting unit is provided with a rear-mounted grass catcher.  The cutting unit includes front and rear rollers and mounted between the rear roller and the grass catcher is a rotary brush.  The brush is mounted for adjustment into and away from engagement with the rear roller and for adjustment into and away from engagement with the turf.  The brush may be driven either in the same direction as or counter to the direction of rotation of the rear roller during forward mowing operation.

Title: Monitoring a gas flow
Inventor: MAEYRAENEN TARMO
IPC: G01F1/7082
Filed: 1992-11-12
Abstract: ABSTRACT OF THE DISCLOSURE      Method and device for monitoring of the composition of a flowing gas.  An oscillation of sound frequency is applied to the gas flow pipe downstream and upstream, and the travel times of the monitoring sound over a certain measurement distance downstream and upstream are detected.  The sound speed or a quantity representing same is determined on the basis of said travel times.  This speed is mainly dependent on the average molecular weight of the gas to be monitored. The temperature of the flowing gas is measured, and on the basis of the measurement of temperature, the sound speed that has been reduced to a certain reference temperature TO is determined from the formula c0 = c . ?(T0/T), which is applicable to an ideal gas and wherein T = absolute measured temperature of the gas, TO = chosen absolute reference temperature, c = measured sound speed, and c0 = sound speed reduced to the reference temperature, or by using a corresponding more realistic formula.  When the reduced temperature differs from its range of expected values, an alarm signal or control signal is given.  Alternatively, the limits of the range of expected values can be reduced to temperature.

Filed: 1993-09-30
Abstract: A method is provided for treating used potassium chloride (KCI) drilling mud for disposal. The process comprises feeding the mud into one end of a rotary tube, advancing the mud through the rotating tube and heating the mud by cascading action using lifters, to expose it to a hot gas stream, thereby partially drying the mud to lumps, further modifying the lumps by contacting them with a burner flame to form clinker pellets, and finally contacting the clinker pellets with a second flame to complete the drying process, producing dried clinker pellets containing the majority of the KCI in the mud, the pellets having a structure that resists the leaching action of water. The pellets further lend themselves to being evenly distributed over fields, so that unwanted excessive concentrations of KCI can be avoided.

Patent CA-2113729-A1 (CA)
Inventor: EBERT FREDERICK J
IPC: G05D1/00
Filed: 1992-08-27
Abstract: A helicopter engine speed reference (66) is increased (117, 118) in response to heavy rotor loading (102) in excess of a threshold at the current descent rate (fig. 4). The reference speed is faded up (117, 118) at a rapid rate to 107 % of rated speed (119). After a fixed time interval (129), reduced rotor loading (122), reduced pitch angle below a threshold magnitude (121) and reduced roll angle below a threshold magnitude (120) will cause the reference speed to be faded down slowly (146, 147) to rated speed (148). Automatic increase in engine reference speed is overridden to 107 % of rated speed (203) when a battle switch is activated (201) and weapons are ready (202). Increases in engine reference speed are prohibited (207) when the helicopter is operating in quiet mode (206) or the helicopter is resting on its wheels (208).

Title: System for adaptively reducing noise in speech signals
Inventor: SOELVE TORBJOERN W
IPC: G10L21/02
Filed: 1994-08-30
Abstract: A method and system are provided for adaptively reducing noise in frames of digitized audio signals that may include both speech and background noise. Frames of digitized audio signals are processed to determine what attenuation (if any) should be applied to the current frame of digitized audio signals. Initially it is determined whether the current frame of digitized audio signals includes speech information, this determination being based upon an estimate of noise and on a speech threshold value. An attenuation value determined for the previous audio frame is modified based on this determination and applied to the current frame in order to minimize the background noise which thereby improves the quality of received speech. The attenuation applied to the audio frames is modified gradually on a frame-by-frame basis, each sample in a specific frame is attenuated using the value calculated for that frame. The adaptive noise reduction system may be advantageously applied to telecommunication systems in which portable radio transceivers communicate over RF channels because the adaptive noise reduction technique does not significantly increase data processing overhead.
