Patent AU-641520-B2 (AU)
Title: Mixer impeller shaft attachment apparatus
Inventor: BORRACCIA DOMINIC
IPC: B01F7/00
Filed: 1991-07-08
Granted: 1993-09-23
Abstract: A mixer impeller, which is adapted to mix and blend liquids and liquid suspensions in industrial and commercial applications and is subject to forces which tend to work the impeller loose from attachment with its driving shaft, is secured to the shaft (12) by collars (34) (locking rings) which are threaded on the ends of hubs from which the blades of the impeller extend. In order to secure the attachment of the collars to the hub, a locking key (42) is inserted between the collar and the shaft. The key has a neck (72) which is located in a keyway also used to key the hub to the shaft, in an impeller mounting area on the shaft. The locking key has a shoulder (70) which bears against surfaces on the collar extending away from the hub. The inner periphery of the collars are tapered outwardly away from the shaft. The neck of the locking key has portions (76) which are deflected against these tapered inner periphers when a pin (42) is inserted through the neck of the locking key. A ramp on the collar mates with a ramp on the key to prevent reverse rotation (working loose) of the collar. In locking position, the keys lock the collar and, therefore, the entire impeller to the shaft, since they are restrained against axial movement by the collar and against rotational movement by being keyed to the shaft and restricted by the ramp on the collar. Removal of the key for impeller replacement and maintenance is readily accomplished using the ramps on the surfaces of the collars and shoulder of the key which bear against each other. Upon removal of the locking pin, the inside of the neck deflects inwardly and the key is urged out of the collar, when the collar is unscrewed from the hub. <IMAGE>

Title: Mixing impellers and impeller systems for mixing and blending liquids and liquid suspensions having a wide range of viscosities
IPC: B01F27/91
Filed: 1991-07-08
Granted: 1993-07-29
Abstract: The impellers have a plurality of fluidfoil blades (12,14,16) and have camber and twist. The geometric pitch or blade angle increases from the tip (24) of the blade towards their axis of rotation in a manner to provide an over pitched condition so that the pitch ratio of the blades at 40% of the blade radius from the axis is greater than the pitch ratio at the tip. The blades are preferably smoothly tapered and increased in width from the tip towards the axis. The impeller blades are mounted on a hub (18) connected to a drive shaft. The blades may decrease in width where they connect to the hub. The pitch angle at the tip is in the range of 18 DEG  to 30 DEG (preferably about 20 DEG ). The angle at the tip of two diametrically disposed blades of a four blade impeller may have a different blade angle at the tip than the other pair of blades. A pair of impellers may be used. These impellers may be of different diameter and disposed in close proximity so that they are in dependent relationship (preferably spaced apart by less than the diameter of the larger impeller). <IMAGE>

Title: Compensation of delay in linearization loop of power amplifier
Inventor: PELLONPERA MARKO
IPC: H03C3/08
Filed: 1998-10-07
Granted: 2002-03-28
Abstract: A method of compensating delay in an linearization loop of a power amplifier and a linearization arrangement of a power amplifier, which arrangement includes an I/Q modulator, one or more power amplifiers to be linearized and generating delay, and a feedback loop including an I/Q demodulator when the I/Q modulator and the I/Q demodulator derive an oscillator frequency from the same local oscillator.

Title: Cct. for automatic transmission of distress signal over telephone line - has automatic dial and motorised contact systems
IPC: H04M11/04
Filed: 1971-06-11
Abstract: The contact releasing the distress or alarm signal short circuits the subscriber's line. An automatic dial system for calling a distress signal receiving station is switch on. The dial codes produced are sent through a contact system operated by a motor. The impulse contact is connected in series with the motor and the subscriber's line. The impulse contact is operated by current lines in the contact system, which are interrupted by non-conducting segments. The operating power for the alarm signal circuit is thereby taken from the telephone network via the subscriber's line. The simple construction ensures trouble free operation.

Title: Digital storage of converted analogue parameters - has analogue signal sampled and converted to digital form followed by entry into memory esp. for data compression prior to display
IPC: G06F17/40
Filed: 1971-11-11
Abstract: The conversion of measured analogue parameters into a digital format, followed by entry into a memory occurs at a rate dependent upon the rate at which the parameter is changing. An analogue to digital converter provides a multi-digit binary number, with the conversion rate controlled by a pulse generator. The digital value is presented to a binary adder operating together with an accumulator that presents partial sums to the adder. Values generated are entered into a memory with the adder cleared after each entry. A memory address register identifies locations and is controlled by a reset signal. A decoder controlled by a count register provides control of the memory address cycle.
