Title: Process for the treatment of natural apatites with a view to the use thereof for storing irradiated fuel elements
Inventor: CARPENA JOELLE
IPC: G21F5/008
Filed: 1994-06-14
Abstract: The invention relates to a process for the treatment of natural apatites with a view to the use thereof for storing irradiated fuel elements. This process consists of contacting a natural apatite powder with an acid aqueous solution, e.g. dilute HN0 3 or HC1 for between a few seconds and 10 minutes.     In this way, the physicochemical properties of the natural apatite are improved by modifying its surface composition in order to make it close to that of hydroxyapatite. This modified apatite can be used as a filling material in irradiated fuel element storage containers.

Title: Method and apparatus for retrieving information relevant to the relief of discomfort caused by dental problems
Inventor: SPRINGHETTI DENNIS J
IPC: G06C3/00
Filed: 1994-07-05
Abstract: The discomfort associated with toothache and other dental related problems can often be temporarily alleviated until such times as professional help can be obtained, if the sufferer is aware of the remedies available. More often than not, however, this simply is not the case and the victim therefore endures. In addition, the action or inac-tion of the victim many times renders what would normally have been a relatively sim-ple dental procedure into a more complex endeavor typically entailing greater expense and discomfiture. The invention as disclosed herein alleviates some of the above problems by pro-viding a simple means whereby sufferers may quickly obtain suitable information rel-evant to providing temporary relief and consists of an efficient and easy to use informa-tion retrieval system comprising a first base plate containing a plurality of suggested solutions to a variety of commonly encountered dental problems. A second plate con-taining a window cut-out and incorporating a number of corresponding problems isaxially mounted to the first plate and free to rotate about the first plate. The system user first identifies the problem via simple observation, locates the problem on the second plate, aligns the problem with an index mark on the first plate and reads the suggested solution through the window cut-out.

Patent CA-2139030-A1 (CA)
Inventor: JAMES STEVEN L
IPC: B66C13/50
Filed: 1994-12-23
Abstract: The disclosure involves a material handling machine, e.g., a crane, having a control circuit switch and a power limit switch.  Disclosed is a new weight assembly having first and second weights.  The control switch is maintained at a position by the first weight and the power switch is maintained at a position by the second weight which is positioned above the first weight.  The weights are telescoped to one another so that vertical weight alignment is assured as the crane hoist bottom block contacts and lifts the first weight.  If the bottom block continues its upward travel past a maximum desired elevation, the first weight (urged by the bottom block) lifts the second weight, permitting the power limit switch to trip and preventing the bottom block from continuing upward.  And the new assembly is ideal where the space available for limit switch weights is restricted.

Title: Motion compensated video processing
Inventor: MARTIN PHILIP DAVID
IPC: G06T9/00
Filed: 1993-07-05
Abstract: Method of motion-compensated video processing such as standards conversion, uses motion vectors assigned on a pixel-by-pixel basis. The pixels of an input video signal are written to locations in a video store (24) determined by the motion vector assigned to that pixel. Multiple vectors can address a single written pixel to enable mixing of backward and forward vectors. A confidence value governs the accumulation of pixels and the later interpolation between motion compensated fields.

Title: Weed inhibiting enclosure members for use with container grown plants and method of use thereof
Inventor: MORI LENO V
IPC: A01G13/02
Filed: 1995-04-07
Abstract: A weed growth inhibiting enclosure member for use with container grown ornamental plants comprises a frusto-conical open-ended tube of thin, flexible light-impervious material of diameter to fit snugly around the container exterior, and of a length such that its upper part overlays the open container top and can be wrapped closely around the plant stem for retention without using a tie. This upper part has spaced perforations of size to permit passage of water to the earth in the container while preventing protrusion of weeds therethrough. The member reduces evaporation and also protects the container exterior against the adverse effects of sunlight and dirt. The weeds are thus denied the light essential to their growth, while access of the wanted plant is unimpeded, so that the weeds remain immature and compete only minimally for water and nutrients. The wrap-ping of the tube part around the plant stem ensures that it will not impede growth of the plant, as might a tie. Preferably the member is provided with a longitudinal tear line or lines facil-itating its removal from the container for a slngle final weed-ing before the plants are shipped, as contrasted with the fre-quent multiple weedings previously required. The tube may be of polyethylene of thickness 1-2 mils, while the holes may be of 3-5mm diameter, preferably of 4mm diameter, spaced from one another from 2cm to 3cm, preferably 3cm. The invention also comprises methods of growing plants in a growth medium in plant containers while inhibiting the growth of weeds in the medium by use of such enclosure members.

Title: Two-port wideband bipolar transistor amplifiers
Inventor: TARALP GUENER
IPC: H03F1/48
Filed: 1992-11-16
Abstract: A wideband amplifier comprises a dual-emitter bipolar transistor arrangement (14; 70, 72; 70, 74, 76) with coaxial transformers (40, 42; 44, 46), each having a high turns ratio and tight coupling between a first toroidal winding (40; 44) on an annular ferrite core and a second, single-turn, winding (42; 46) constituted by a metal container of the transformer. The second windings are coupled between respective emitters and signal ground, and the first windings are connected between the transistor base and collector, respectively, and signal ground. An input signal is supplied to the base, and an output signal is derived from the collector. The dual-emitter bipolar transistor, which has four terminals, is thereby transformed into a two-port (input port and output port) device which facilitates impedance matching, provides a linear and constant gain over a large bandwidth, provides high isolation of the input from the output, and provides low noise at the input and a high level at the output.

IPC: H05B41/292
Filed: 1994-03-24
Abstract: When connecting external wiring to a circuit board, which is inserted in a housing arrangement, there is the conventional way a backpanel having connector elements for receiving corresponding connector elements on the circuits board.  The external wiring is connected to contacts on an exchangeable and removable connector unit.  The unit is inserted in the housing in a similar way as a circuit board but is not connected to the backpanel and comprises connector contacts for connection with corresponding connectors on the circuit board.  When the circuit board is inserted into the housing thus electrical contact is obtained both with the contacts on the backpanel and with the contacts on the wiring connector unit.  From the contacts on the connector unit leads extend to the various contact pins, which are located easily accessible from the front of the housing.
