Patent CA-2079564-A1 (CA)
Inventor: BOWDEN RAYMOND D III
IPC: G06F13/28
Filed: 1992-09-30
Abstract: ABSTRACT OF THE DISCLOSURE      A  memory  system  couples to  a  local  bus  of  a microprocessor  includes  at  least  a  pair  of  dynamic random  access  memories  (DRAMs)  and includes means for storing  the  first address of an address sequence at the beginning  of each burst operation and uses predetermined bits  to generate any one of the set of address sequences as  a  function  of  the  states  of these bits.  A first predetermined  address  bit  is  used to select different sequences   of   addressed   readout  data  words  to  be transferred  by  the pair of DRAMs to the user.  A second predetermined  address bit is complemented to reverse the two  high  order address responses with the two low order address  responses  of specific address sequences.  These operations  are  utilized  to all of the required address sequences within the different subgroups.

Abstract: DESCRIPTIVE ABSTRACT              Process for the conditioning or recycling of used ion cartridges.           The invention relates to a process for the treatment of ion cartridges or elements ensuring the treatment of contaminated waters of storage ponds or pools for nuclear reactor fuels.  By cartridge trans-fer and suction means, said treatment consists of extracting the ion exchange resins contained in the cartridge.           When the resin has been extracted, a con-ditioning process makes it possible to decontaminate and then condition, independently of the resinous substance, the metal structure constituting the cartridge.           When the resin has been extracted, a re-cycling process makes it possible to clean the impurities from the metal structure and fill it again with new resin.           The invention has applications in the nuclear field and in particular in the field of treatment and conditioning of nuclear waste.    (No drawing).     B. 10942 BM

Abstract: The harness includes a torso engaging device made of nylon strips conformed in a figure eight pattern; the arms of the wearer extending through the loops.  An arm cuff is also provided which engages  about  the  upper arm of  the wearer and is connected to the torso engaging device by means of rubber tubings which act to limit range of motion of the arm.   Also, to keep the torso engaging device from riding up around the arms of the wearer,  further rubber tubings engage a lower torso strip section to clips engaged to the harness wearer's belt.  The harness can be used for either arm,  or both arms,  as desired.   Also, with simple modifications, the harness could be used to control range of motion of other joints as well.

Title: Traction boards
Inventor: MORALES RAMI
IPC: B60B39/00
Filed: 1993-03-22
Abstract: ABSTRACT            Driving conditions during winter can be a hassle after a snowfall, where vehicles are unable to move or steer away from a stationary post. Once a vehicle is exposed to these outdoor conditions, it becomes quite a frustration for the driver being prone.          With this invention, helplessness and isolation are eliminated with the aid of a portable drawing or pulling mechanism utilizing a skid-like platform that prevents the wheel of a vehicle from spinning, but rather roll along a furrowed surface.

Patent CA-2117286-A1 (CA)
Inventor: LIFSHITS VLADIMIR
IPC: F23D14/46
Filed: 1994-05-26
Abstract: A low NOx burner (2) includes a primary air and fuel discharge assembly which, in turn, includes a burner plate (6) having a plurality of slots (32) from which fuel gas jets and combustion air are discharged.  The slots are arranged such that the width of the recirculation zones between adjacent slots substantially varies between the central region of the burner plate and its perimeter.  With this construction, the local ignition patterns vary such that local oscillations of flame front occur at different frequencies so that vibrations are greatly dampened and resonance problems in the furnace minimized or eliminated.   In applications where high excess air is not desirable, such as boiler applications, the burner is modified by providing a secondary fuel and flue gas injection assembly (80) to form a two stage burner (2').  In the preferred embodiment, the secondary injection assembly includes a plurality of discrete fuel and flue gas injection tubes (82, 94) arranged around the primary air and fuel gas discharge assembly (50).  The secondary fuel and flue gases are directed radially inward and downstream from the burner plate so that they mix with the combustion air entering through the burner plate slots (32) in a secondary combustion zone.  The resulting delay in the combustion of the secondary fuel gas and the need for heating the flue gas lowers the overall combustion temperature, which in turn reduces the NOx formation in the second or downstream combustion zone.

Title: Novelty noise maker
Inventor: BODEN BONNIE C
IPC: G10K3/00
Filed: 1994-05-16
Abstract: A novelty noise-maker includes a handle which can be gripped adjacent one end, and which has a transverse bore adjacent the second end. A shaft is slidably mounted in the transverse bore and supports a head member at one end and a stop member at the other end, both members being too large to pass through the bore. When the noise-maker is shaken vigorously, the shaft reciprocates quickly within the bore, and the members at other end come into contaet with the handle portion, thus generating a "clacking" noise.

Title: Method and apparatus for crushing material of different grain size
Inventor: BRUNDIEK HORST
IPC: B02C23/32
Filed: 1994-07-05
Abstract: ABSTRACT OF THE DISCLOSURE          A method and an apparatus for crushing material of differing grain size are disclosed.  The material is ground into particles in a grinding pan of a mill, then spun over the edge of the pan and conveyed upwards in a helical flow close to the casing wall of the mill by a gas-directing device producing a rotary flow.   Centrifugal  force and gravity result in the formation of an outer particle flow of oversize material.   As a vented concentrated flow,  the oversize material does not participate in the grinding and classifying process and at least a portion of the material is removed from the grinding and classifying chamber.   A device for removing the oversize material is positioned on the casing wall above the grinding pan, and is connected to a mechanical conveying device.  Some or all of the oversize material  may  thereby  be  returned  to  the  grinding  and classifying chamber.
