Title: Phase-shifting transformer system
Inventor: LARSEN EINAR V
IPC: H02J3/18
Filed: 1992-06-15
Abstract: A faster, more controllable phase-shifting transformer system (20, 120) is provided, along with a method of retrofitting and upgrading a preexisting system for faster operation, and a method of applying a desired phase shift to the voltage on a polyphase transmission line (22, 122). A phase-shifting transformer set has series and regulating transformers (30, 40) coupled together by a switching network (50). An optional modulator (60, 80, 90) modulates the phase shift voltage about a nominal level established by the switching network (50). A thyristor augmented switching network (250, 350, 450) may have a pair of thyristor valves (206, 208;  406, 408) augmenting a reversing switch (204; 404) or a thyristor (311) augmented load tap changer (310) for varying the phase shift discreet step magnitude. For continuous effective phase shift control, a thyristor valve (416, 416', 416'') and a harmonic filter (418, 418', 418'') are in parallel with each excited winding (446, 447, 448), and a harmonic filter (414) is in parallel with each regulating winding (444).

Patent CA-2097209-A1 (CA)
Inventor: MERENDA JOSEPH T
IPC: H01Q1/26
Filed: 1993-05-28
Abstract: Synthesizer radiating systems providing efficient wideband operation incorporate a radiating element (20a), such as a loop, dipole or whip, which has dimensions which are small relative to wavelength in the radiated frequency band. Energy dissipation is substantially reduced by cycling stored energy back and forth between a radiating element (20a) having a first reactance and a storage element (22a) having the same or opposite reactance, in order to achieve energy efficiency along the lines of a narrowband tuned-circuit antenna. wideband operation is achieved by synthesizing a representation of an input waveform (at 28) by actively controlling (30) solid-state switching devices (24), responsive to rate control and direction control parameters, which are interactive with the energy transferred between the opposite reactances. Higher efficiencies are achieved by bipolar circuits providing separate positive and negative energy transfer paths between a radiating element and a storage element. Systems as described provide relatively high radiated power levels with broadband operation and reduced power supply requirements, permitting provision of readily transportable units with small antennas for applications in which combinations of size, radiated power, bandwidth, power use and mobility are important.

Inventor: HAIGHT ROBERT E
IPC: F16H59/04
Filed: 1993-07-29
Abstract: A shift lever assembly includes plate having a plurality of intersecting slots formed therein, including fore-and-aft extending directional gear slot and a transverse extending neutral slot.  The neutral slot has a recess formed on one side thereof.  A lever has a movable shaft received in and guided in the slots.  A latch member is engagable with the shaft to releasably hold the shaft in the recess and prevent inadvertent movement of the shaft from the neutral slot into the directional gear slot.  A shaft spring is biased to urge the shaft away from the directional gear slot.  A latch spring is biased to urge the latch member towards the recess so that the shaft, latch member, the latch spring and recess cooperate to deter inadvertent movement of the shaft in a direction generally parallel to the neutral slot and out of the recess and out of the neutral slot.  The latch member is pivotal away from the recess by the shaft when the shaft is moved away from the recess and in a direction generally transverse to the neutral slot, to thereby permit movement of the shaft in a direction generally parallel to the neutral slot and out of the recess and out of the neutral slot.

Title: Plant chitinase gene and use thereof
Inventor: MIKKELSEN JORN D
IPC: A01H5/00
Filed: 1992-04-07
Abstract: A DNA sequence comprising the sugar beet chitinase 4 DNA sequence shown in SEQ ID NO.1 or an analogue or subsequence thereof is disclosed. The polypeptide encoded by the DNA sequence, also termed the sugar beet chitinase 4 enzyme, has a high antifungal activity due to a bifunctional catalytic activity (i.e. a chitinase and a lysozyme activity) which makes the enzyme highly effective in inhibiting the growth of chitin-containing fungi. An even improved antifungal effect is obtained when the sugar beet chitinase 4 enzyme is used in combination with other pathogenesis related proteins, especially in combination with a second different chitinase and a .beta.-1,3-glucanase. A preferred use of the DNA sequence disclosed herein, optionally in combination with DNA sequences encoding other pathogenesis related proteins, is in the construction of genetically transformed plants, especially genetically transfrmed sugar beet plants, having an increased resistance to chitin-containing fungi as compared to untransformed plants.

Title: Process for reducing data in the transmission and/or storage of digital signals from several dependent channels
Inventor: HERRE JURGEN
IPC: G10L25/00
Filed: 1992-10-13
Abstract: A method for reducing data during the transmission and/or storage of the digital signals of several dependent channels is described.   The dependence of the signals in the channels, e.g. in a left and a right stereo channel, can be used for an additional data reduction. Known methods such as middle/side encoding or the intensity stereo process lead to perceptible interference in the case of an unfavourable signal composition.   The method according to the invention avoids such interference, in that a common encoding of the channels only takes place if there is an adequate spectral similarity of the signals in the two channels.   With the aid of the method according to the invention an additional data reduction can be achieved in that in those frequency ranges where the spectral energy of a channel does not exceed a predeterminable fraction of the total spectral energy, the associated spectral values are set at zero.   As the method is independent of the specific internal form of the encoding method, it is universally usable.
