Title: Microspore-specific regulatory element
Inventor: MIKI BRIAN
IPC: C12N15/82
Filed: 1995-11-08
Abstract: A novel DNA regulatory element that confers microspore-specific gene expression has been discovered, isolated, and characterized. The microspore-specific regulatory element can be used to control the expression of a foreign gene that disrupts the function of microspores. Thus, the control of pollen production can be achieved by using the microspore-specific regulatory element to produce male-sterile plants. Various methods can be used to restore male fertility in the F1 generation of such male-sterile plants. In addition, the microspore-specific regulatory element can be used to confer resistance to viral and insect pests.

Patent CA-2216178-A1 (CA)
Title: Tangential separator
Inventor: JOHNSON RICHARD D
IPC: B01D45/12
Filed: 1997-09-17
Abstract: A separating system for separating material transported by air utilizing apparatus having a tangential inlet for a stream of air and entrained material, a bottom material exit, a boundary wall air exit and a central interior air exit. Each air exit includes a perforated wall or screen through which air is removed or separated from the entrained material.      Enhanced separating action is achieved through coupling two such separators in a loop arrangement such that the material discharge from a first separator is conveyed via a relay stream of air to serve as the input to a second separator, while the entire air exhaust from the second separator is returned as one of a plurality of inlet streams to the first separator. A further advantage is realized by partitioning the air exhaust of the first separator into a plurality of parallel passageways which can be individually closed. Associated with each passageway is a nozzle through which a compressed air blast is introduced into the passageway that is effective to reverse the air flow therein and clear the associated perforated wall or screen of accumulated scrap material without halting the material separating operation.

Patent CA-2220214-A1 (CA)
Title: Linear guide device of solid lubrication type
Inventor: SASAKI AKIRA
IPC: F16C33/32
Filed: 1997-11-04
Abstract: The linear guide device of the present invention has a structure in which a solid lubricating film is applied on the ball guide grooves of the main rail and the ball circulating paths of the slider, and the surfaces of the balls housed to be rotatable and movable in the ball circulating paths, are formed porous.  Thus, when the slider is urged to move with respect to the main rail, and the balls rotate and move within the ball circulating paths, the balls are brought into contact with the solid lubricating films on the ball circulating paths and the films on the ball guide grooves of the main rail.  Due to the effect of the surfaces of the balls, the solid lubricating film is transferred onto the surfaces of the balls, thus achieving solid lubrication.

Patent CA-2224445-A1 (CA)
Title: Bed system
Inventor: ROSSDEUTSCHER RALPH H
IPC: A47C23/06
Filed: 1997-12-10
Abstract: The bed system has a rectangular frame, with a mattress assembly mounted on the frame. The mattress assembly has upper and lower wooden strip layers and intervening foam blocks. Each wooden strip layer has a plurality of laterally-oriented wooden strips arranged in proximity to each other from top to bottom of the frame, with each strip extending from one side panel to the other side panel. There are three foam blocks, namely two outer foam blocks and one central foam block, running from head to foot of the bed between the wooden strip layers. The side panels have inwardly-facing shoulder portions running the length thereof, and the wooden strips of the lower wooden strip layer rest on the shoulder portions, with the outer foam blocks extending outwardly beyond the wooden strips so as to be in general vertical alignment with the outer walls of the side panels. This permits conventional North American fitted sheets and/or bed skirts to be used if desired. Spaced-apart buttons on the outside of each outer foam block are tied to corresponding buttons on the opposing outer foam block, to prevent the foam blocks from moving laterally outwardly beyond the outerwalls of the side panels. Preferably the bed system includes at least one elevating mechanism to permit the head of the bed and/or lumbar and leg portions to be raised. In double, queen or king sized versions of the invention, a central support member runs longitudinally between the head and foot panels, with support rails on either side thereof. Two of the mattress assemblies are arranged side by side, one on either side of the central support member, the central support member being configured to act the same as a side panel for each of the two mattress assemblies.

Title: Adaptive pneumatic wing for fixed-wing aircraft
Inventor: KAMMER RES
IPC: B64C3/30
Filed: 1997-05-14
Abstract: The claimed pneumatic wing has a continuous, airtight envelope (8) made of a textile base material and subdivided into cells (15) by a plurality of textile webs (3). The envelope (8) forms a top skin i (1) and a bottom skin (2), such that the top skin (1) in part (towards the down-draft edge (5)), the bottom skin (2) entirely or in part, can be supplemented by an upper and a lower double-skin (16, 17). The double-skins (16, 17) are connected to the envelope (8) between the attachment lines of the webs (3), thus forming between the envelope (8) and double skins (16, 17) channels (19) to which compressed air can likewise be admitted. This changes the shape of the wing profile. In addition, the webs (3) can in part have a similar airtight and double-walled design, here too creating channels (19) to which compressed air can be admitted. This reduces the height of the wing profile. With a suitable combination of these options, part of the wing can be designed as aileron or landing flap, or the wing as a whole can be optimized with respect to the selected flying speed.

Title: At least partly fused particulates and methods of making them by flame fusion
Inventor: CASTLE RICHARD B
IPC: C03B19/10
Filed: 1996-10-31
Abstract: The disclosure describes methods for producing bulk, particulate material that includes solid, generally ellipsoidal particles. Irregularly shaped feed particles with average particle sizes of up to 25 microns on a volume basis are dispersed in at least a portion of a combustible gas mixture by application of force and/or fluidizing agents. The combustible mixture with particles in suspension is then delivered, while controlling agglomeration or re-agglomeration of the particles, to at least one flame front. There, the mixture and suspended particles are uniformly distributed across the surface(s) of and passed through the flame front(s) with a high concentration of particles in the mixture. This flame front and the resultant flame(s) with suspended particles are located in at least one "wall free" zone. In such zone(s) the flame(s) may expand while the particles are maintained in dispersion and heated, with controlled and highly efficient application of heating energy. At least partial fusion occurs within at least the surfaces of the particles at high thermal efficiencies, while agglomeration of particles during fusion is inhibited.
