Abstract: An electro-mechanical drive apparatus uses a single variable speed motor (20), two one-way clutches (42, 66), and a hydraulic accumulator (48) to provide both hydraulic power for the linear motion axes and rotation of the plasticizing screw (14) in an injection molding machine. When engaged, the first one-way clutch (42) couples the drive motor (20) to the pump stack (26), while the second one-way clutch (66) couples the motor (20) to the feed screw (14). During rotation of the drive motor (20) in a forward direction, (a) the first one-way clutch (42) engages, rotating the shaft of the hydraulic pump stack (26) to power the machines hydraulic systems and charge the accumulator (48); and (b) the second one-way clutch slips. When the drive motor (20) is rotated in a reverse direction, (a) the second one-way clutch (66) engages, rotating the feed screw (14), and (b) the first one-way clutch (42) slips. Preferably, the drive apparatus is associated with a double shaft motor (20) mounted adjacent separate drive couplings for the feed screw (14) and hydraulic pump stack (26).

Abstract: The invention relates to a power converter comprising several semiconductors (1) and direct voltage and alternating voltage buses (8/9, 4) for electric contact between the direct and alternating voltage connections (3, 2) of the power semiconductors (1). The buses are divided into two parts so that the alternating voltage bus (4) and the direct voltage bus (8/9) do not come into physical contact with each other. One advantage of the invention is that no creepage paths between the direct voltage and alternating voltage buses need to be taken into consideration.

Patent CA-2351821-A1 (CA)
Inventor: TUCKER CLIVE
IPC: F16H47/04
Filed: 1999-11-24
Abstract: A parallel hydromechanical continuously variable transmission has a housing (107) that holds a make-up pump (52), and has internal cavities for holding operating assemblies of the transmission, including an axial piston pump (50) and an axial piston motor (60). The pump (50) and motor (60) each has a rotating element (206) and a non-rotating element (258). Each non-rotating pump element is mounted for tilting movement on trunnions (258P) in its own respective pair of mounting journals in the housing (107). The tilting axes of the non-rotating elements (258) lie transverse to the axes of rotation of the rotating elements (206). The pump (50) and the motor (60) are disposed side-by-side in the housing (107) with the axes of rotation approximately parallel to each other. A stationary manifold (70), fixed to the housing (107), has one surface in contact with the rotating pump element (206P) and a second surface in contact with the rotating motor element (206M). Fluid passages (149, 208) open in the two surfaces in fluid communication with the pump and motor cylinders (206) through a pump/manifold interface. Internal fluid passages (149, 208) in the stationary manifold (70) convey fluid pressurized in the pump (50) directly to the motor (60), and convey spent fluid displaced from the motor back to the pump. The transmission ratio is controlled by the tilt angle of the non-rotating pump and motor elements (258). A tilt angle control apparatus (100) attached  to the housing (107) and to the non-rotating pump and motor elements (258) governs that tilt angle.

Abstract: An optical circuit has a loop mirror coupled to a 3-dB coupler, with a chirped fiber Bragg grating coupled in the minor loop. When a beam of light from a broadband light source is launched into the circuit, the circuit functions as a tunable notch filter or as a bandpass filter depending on which output port of the coupler is used to monitor the response. An interference fringe pattern generated in the response of the circuit enables to determine dispersion of the chirped Bragg grating.

Inventor: GUDMUNSON DANIEL
IPC: H04N5/7826
Filed: 2001-08-22
Abstract: A method and device for performing digital signal magnetic recording and reproduction in analog format on a medium, using a conventional analog video tape recorder (VTR). The digital signal is digitally modulated and inserted into the active part of scan lines of a standard composite video signal, and converted to an analog signal for storage on the medium. When the signal is reproduced from the medium, the analog signal is converted to a digital composite video signal, and the modulated data is extracted from the active part of the scan lines and demodulated to restore the original digital signal. To improve the synchronization between the demodulation and modulation stages, during demodulation the color burst of the composite video signal may be used as a pilot signal to recover the sampling clock and regenerate the one or multiple carriers. Error correction coding may be employed to reduce the signal-to-noise ratio of the reproduced signal.

Title: Multiple band optical multiplexer and demultiplexer
Inventor: DAVIES MICHAEL
IPC: H04J14/02
Filed: 2002-02-05
Abstract: A grating based optical wavelength demultiplexer that can be used for multiple wavelength bands over a wide wavelength range is presented. The spectral response of the device is cyclic. The free spectral range of the grating is designed to be large enough to contain all the wavelength channels to be demultiplexed within a band but small compared to the overall wavelength window of the network application so that a multiplexed signal within any one of the wavelength bands within the application window can be demultiplexed by the same device. This device, being bi-directional will also operate as a multiplexer. By using such a cyclic design, an organization will not need to stock different parts for each band and thus significantly reduce the inventory cost.
