Patent CA-2131646-A1 (CA)
Title: Mine
Inventor: GROSSWENDT WERNER
IPC: F42B5/02
Filed: 1994-09-08
Abstract: Abstract Mine The present invention relates to a mine (1) with at least one ejectable submunitions container (3) that is arranged within a cup-shaped launcher (2), and with a propulsion system (8) that delivers the submunitions container (3) to a specific altitude range.            In order to ensure that the propulsion system (8) occupies only a small structural volume, entails only low costs by the use of small quantities of propellant charge, and also operates reliably and safely, it is proposed that the propulsion system (8) be arranged not in or on the submunitions container (3), but rather in the base part of the cup-shaped launcher (3). When this is done, it is advantageous that the propulsion system (8) consist of a high-pressure chamber (9) that is proximate to the base (7) of the launcher, with the propulsion charge (15) therein, and a low-pressure, chamber (10) that is proximate to the submunitions container. The low-pressure chamber (10) and the high-pressure chamber (9) are separated from each other by a common perforated plate (12) that incorporates nozzles (holes) (11).

Abstract: ABSTRACT OF THE DISCLOSURE Process of imparting conductivity to a three-dimensional net-shaped porous sheet can be performed effi-ciently before carrying out electroplating process.  Fine metallic powders are applied to the porous sheet made of a foamed sheet, a nonwoven sheet, a mesh sheet or a plurality of sheets layered one on the other, so that a conductive metallic layer is formed on the porous sheet.   Then, an electroplated layer is formed on the surface of the conduc-tive metallic layer.  The conductive metallic layer remains when the porous sheet burned out.  Consequently, a metallic layer of the conductive metallic layer and the electroplat-ed layer forms the metallic framework of the metallic porous sheet.

Title: Process for purifying liquid natural gas
Inventor: RHOADES GEORGE D
IPC: F25J3/08
Filed: 1994-09-23
Abstract: PROCESS FOR PURIFYING LIQUID NATURAL GAS                Abstract of the Invention The present invention is directed to a process for increasing the methane content of liquid natural gas to provide an essentially pure liquid methane product. In the process, a liquid natural gas feed stream is introduced into a first heat exchanger in indirect heat exchange with a purified methane vapor stream so as to liquify the purified methane vapor stream and to provide a purified liquid methane product.  The heat exchange results in increasing the temperature of the liquid natural gas feed stream to a temperature just below the dew point of the liquid natural gas feed stream so as to partially vaporize the liquid natural gas feed stream to provide a mixture of a major amount of substantially pure methane vapor and a minor amount of liquid containing methane and higher hydrocarbons.   The mixture of vapor and liquid from the first heat exchanger is transferred to a low pressure separator to provide a liquid bottom fraction and a purified methane top vapor fraction.  At least a portion of the liquid bottom fraction and all of the top vapor fraction are transferred to a second heat exchanger in indirect heat exchange with the vapor fraction after the vapor fraction has been processed to change the temperature and pressure of the vapor fraction.  The vapor fraction exiting from the second heat exchanger is transferred through a compressor and an aftercooler to provide a processed purified methane vapor fraction which is returned to the second heat exchanger for use as a heat exchange medium in the second heat exchanger.  The processed vapor fraction after its return through the second heat exchanger is introduced into the first heat exchanger to provide a heat exchange medium for the partial vaporization of the liquid natural gas feed stream and to provide a purified liquid methane stream.

Title: Antenna assembly for radio circuit and method therefor
Inventor: MOLLER PAUL J
IPC: H01Q1/36
Filed: 1994-02-14
Abstract: An antenna assembly (100), and associated method, for a radio, such as a portable radiotelephone, which is of minimal physical dimensions and which is operable over a wide range of frequencies. A  length of wire (106) is helically-shaped and includes at least a portion of winding. A capacitive top-hat (136) is positioned at an end portion of the wire. By increasing the number of windings of the wire (106), the height of the antenna assembly is reduced, but such reduction also reduces the size of the bandwidth of frequencies over which the antenna assembly is operable. Increase in the size of the surface area of the capacitive top-hat (136) increases the size of the bandwidth over which the antenna assembly is operable. Selection of the top-hat size and the number of windings permits both physical dimensions of the antenna assembly and the size of the bandwidth to be selected.

Title: Method and apparatus for in-situ treatment of landfill waste and contaminated soil
Inventor: CIRCEO LOUIS J
IPC: C10B53/00
Filed: 1993-08-17
Abstract: A method is disclosed according to a first and second embodiment in which a plasma arc torch is used to vitrify and remediate a site containing municipal waste, contaminated soils, resulting from a hazardous material deposit or spill, or contaminated buried objects. The process steps of the first preferred embodiment involve drilling a series of holes into the waste material mass at proper spacing, inserting and operating a plasma arc torch in each drilled hole to pyrolize, remediate and vitrify the waste materials and allowing the melted materials to cool and harden. During the process, a gaseous by-product is produced and collected in a hood which is attached to scrubbing and chemical cleaning apparatus. The resultant gases are commercially useful as fuel gas and the vitrified residue is significantly smaller in volume than the original waste material volume, thus substantially extending the useful life of the landfill site and ultimately providing a firm foundation for construction.        The contaminated earthen material or subterranean deposit is pyrolyzed, melted or solidified by the plasma torch which is energized at the bottom of a cased, vertical borehole, and then gradually raised to the surface. An array of boreholes, appropriately spaced, will remediate an entire mass of contaminated material.       Similarly, buried objects such as metal drums containing contaminants and underground storage tanks may be selectively remediated at their specific buried depth.      Similar use is made of the plasma torch in a variation of this embodiment with the additional step of processing at selected underground locations in the borehole array to create a sealed horizontal layer, vertical cutoff walls or a sealed basin as a barrier against further leaching of contaminants into surrounding soil and groundwater.     Gaseous by-products of the pyrolysis process are collected, treated and processed, as appropriate.

Patent CA-2143925-A1 (CA)
Title: Differential Gear
Inventor: MIMURA KENJI
IPC: F16H48/12
Filed: 1995-03-03
Abstract: A   small,   inexpensive,   comparatively   simple differential  gear,  having  reliable  revolution  difference restricting effects includes a rotary casing and a retainer having a common rotation axis.  Torque is transmitted to a groove of a pair of rotary members via rolling elements so the rotary members rotate with the casing. When a revolution difference occurs between the rotary members, rolling elements retained in guide slots of the retainer roll along the grooves of the rotary members so there is reciprocal movement within the  range of the guide slots.   When a  force causing a revolution difference between the rotary members is applied from the   side of only one of the rotary members,  the resulting reaction force restricts the revolution difference between the pair of rotary members.   This is because the rolling elements which come to the following side when the revolution difference exists trail the groove which comes to the  leading side when a revolution difference occurs in response to their own movements. Reliable torque-sensitive revolution difference restricting effects are provided without a  special  mechanism  to  obtain  a  revolution  difference restricting effect.
