Patent AU-2463499-A (AU)
Title: Multiple watermarking techniques
Inventor: RHOADS GEOFFREY
IPC: G06T7/00
Filed: 1999-01-20
Abstract: Multiple digital watermarks, each of which has different characteristics, are embedded in a document. The characteristics of the various watermarks are chosen so that each of the watermarks will be affected in a different manner if the document is subsequently copied and reproduced.The detection process or mechanism reads each of the watermark and compares their characteristics. While wear and handling may change the characteristics of the digital watermarks in a document, the relationship between the characteristic of multiple digital watermarks in a document will never-the-less give an indication as to whether a document is an original or a copy of an original.

Patent AU-3016592-A (AU)
Title: Rectification system for non-resonant switched converters
IPC: H02M3/335
Filed: 1992-12-16
Abstract: Applicable to non-resonant switched mode power supplies with voltage regulation by means of pulse width modulation. Its objective is to achieve a reduction in the amplification in the value of input capacitance (Miller effect) at the instants of switching of the MOSFET rectifier transistors, and to prevent the appearance of a shortcircuit in the main power supply unit at such instants. The first of these objectives is achieved by having the switching of the MOSFET rectifier transistors take place at a value of drain-source voltage equivalent to the cathode to anode voltage drop of a conducting diode (approximately zero volts). The second objective is achieved assuring that change of state from cutoff to conduction, or vice versa, of the MOSFET rectifier transistors never occurs simultaneously with the change of state of the other switches in the converter. <IMAGE>

Title: Friction hinge assembly
IPC: E05D11/06
Filed: 1992-11-03
Abstract: There is disclosed a friction hinge assembly capable of providing hinged motion of two elements with a programmable frictional torque. The frictional torque can be made to vary with the angular orientation of the two hinged elements. The frictional hinge assembly is comprised of a band wrapped around a pintle which is constrained to move rotationally with the first hinged element. One end of the band has a lug configured to press against the second hinged element, exerting thereupon a torque about the pintle. The other end of the band has a tail to which is applied a controlled force to produce the desired frictional torque between the band and the pintle.

Title: A method and apparatus for performing ridge preservation and implant treatment
Inventor: ASHMAN ARTHUR
IPC: A61C8/00
Filed: 2000-10-19
Abstract: A method for preserving the alveolar ridge surrounding a presently extracted root socket by backfilling the socket with bone graft material and installing an implant in the root socket area either immediately before backfilling or after backfilling and a delay in which new bone is allowed to grow into the bone graft material. In one embodiment, the dental implant is installed apically into the root socket immediately following root extraction. The open area of the root socket surrounding the implant is then backfilled with bone graft material immediately after implant placement. The implant is preferably a threaded implant (but it can be a cylinder-type) which is placed approximately three to six millimeters apically to said root socket. The bone graft material comprises synthetic bone alloplast such as Bioplant(R) HTR(R) and is hydrated using the patient's own blood obtained from the patient's bleeding extraction socket after penetration but prior to insertion of the bone graft material and the implant into said root socket. As an alternate embodiment, the presently extracted root socket is filled with bone graft material and primary or non-primary closure of the extraction site is performed. Bone-growth is promoted in the root socket by the bone graft material for 2-12 months. Then, after sufficient bone growth has been promoted, an implant is installed in the extraction site area in the normal manner.

Patent AU-3448684-A (AU)
Title: Phase detection synchronisation
Inventor: MCCABE DAVID JAMES
IPC: H03K5/26
Filed: 1984-10-19
Abstract: A phase detecting arrangement includes an edge-triggered flip-flop phase detector which produces alternate logic 1 and logic 0 outputs in response to the arrival at respective detector inputs of set and re-set pulse transitions. These pulse transitions occur in pulse trains derived respectively, from external synchronizing signal generating means and a voltage-controlled oscillator the frequency of which is to be synchronized with that of the synchronizing signal. First and second sampling devices are associated with the phase detector for sampling the output from the detector when set and re-set transitions occur at inputs to the first and second sampling devices. Outputs from the sampling devices are suitably gated to produce an overall logic 1 or logic 0 output from the arrangement whereby an existing output from the arrangement is perpetuated when the phase detector output sampled indicates that at least two consecutive set or re-set pulse transitions have occurred without the intervention of an opposite type transition.

Title: Convertible multi-color printing machine for the recto-verso printing of especially bank notes
IPC: B41F11/02
Filed: 1989-05-11
Abstract: The printing machine is composed of two essentially identically constructed halves which each have an impression cylinder (4, 14), an image transfer cylinder (6, 16) resting against this, a blanket cylinder (7, 17) and a collect-printing plate cylinder (5, 15). In the offset-printing position, the blanket cylinder (7, 17) rests against the impression cylinder (4, 14) and is inked by offset plate cylinders, while the collect-printing plate cylinder (5, 15) is inoperative. In the collect-printing position, the blanket cylinder (7, 17) is moved away from the impression cylinder (4, 14), is inked by color selector cylinders (8, 18) and itself inks the collect-printing plate cylinder (5, 15) which rests against the image transfer cylinder (6, 16). Moreover, in both printing positions, the image transfer cylinder (6, 16) is inked by the plate cylinder (10, 20) of an additional single-color printing unit. The paper first loops partially round the impression cylinder (4) of the first machine half and is thereby printed directly on one side by the image transfer cylinder (6) and, in the offset-printing position, also by the blanket cylinder (7) and then loops partially round the impression cylinder (14) of the second machine half, the other side of the paper being printed in a similar way.

Title: Expanded information capacity for existing communication transmission systems
Inventor: HARTSON TED E
IPC: H04B1/04
Filed: 1999-04-16
Abstract: A system for transmitting digital programming includes a program source providing digital information, circuitry for modulating the digital information onto a visual carrier modulated with analog television programming, and a visual transmitter coupled to the modulating circuitry. Using a phase modulation method, the system phase modulates the digital information onto a visual carrier, reduces the baseband frequencies of the phase modulated visual carrier, and amplitude modulates the phase-modulated video carrier onto a video signal. The amplified and encoded video signal are combined with an amplified sound signal and transmitted. Using an additive method, the system modulates the sidebands of the video carrier with the digital information and amplitude modulates the video signal onto the video carrier. The data-modulated sidebands are phase-shifted such that they will be in quadrature with the amplitude-modulated video signal. The system combines the amplitude-modulated video carrier and the data-modulated quadrature sidebands. With a blended multiplicative/additive method, the system provides phase modulation and quadrature sideband addition to provide an optimized result.
Patent AU-3717199-A (AU)
Title: Flow meters
Inventor: BAILEY LLOYD STAN
IPC: G01F1/44
Filed: 1999-04-26
Abstract: A flow meter for use in an oil well has a central bore region in which an annular tube is fixed co-axially with the central bore region by a ring, which also seals the gap between the inner bore of the central bore region and the tube at its downstream end, thus forming a pocket open to the direction of fluid flow through the central bore region. The pocket brings the fluid to rest, thereby converting all of the dynamic pressure of the fluid into static pressure. This has the effect of maximizing the pressure differential obtainable between the central bore region and a position upstream of the tube, which allows an electronic calculation to be made to provide a more accurate flow rate measurement than would have been possible without the pocket.
