Title: 電気式圧力センサーおよび弁アクチュエータを有するキャニスタ通気弁
IPC: F16K37/00
Filed: 1998-02-11
Abstract: (57)【要約】
蒸気収集キャニスタの通気弁３２Ａは、診断試験中に蒸発ガス・スペースの圧力を測定する電気式圧力センサー８６と、診断試験中に閉じた通気弁を操作する電気アクチュエータ５８とを含む。蒸発ガス制御システムに弁を用いると、システムに弁を設置するのに必要な電気接続部および流体接続部両方の数が減少する。圧力センサーの位置が遠いので、タンク燃料の飛びはね等による圧力遷移がセンサーに与える影響が弱まる。

Inventor: BERKEY GEORGE EDWARD
IPC: C03B37/018
Filed: 1984-09-04
Abstract: This invention relates to a method forming fluorine-doped glass. A coating of glass particles is deposited on the surface of a cylindrical rod of high purity glass. The coated rod is inserted into a furnace which contains a cylindrical muffle formed of high silica content glass. A fluorine-containing atmosphere is flowed through the muffle and over the outer surface of the coating of glass particles and also flows inwardly through the interstices thereof. The temperature within the furnace is sufficiently high to cause fluorine to diffuse into the surfaces of the glass particles and to cause the particles to fuse and form a fluorine-containing dense glass coating on the surface of the rod.

Title: Drying low-rank coal using super-heated gas
Inventor: GREENE M M
IPC: C10L9/00
Filed: 1985-11-26
Abstract: Process and apparatus are disclosed for removing a substantial portion of water and impurities from low rank coal and peat, whereby an improved coal or peat product (not found in nature) is obtained. The low rank coal and peat are subjected to a superheated gaseous medium, thereby substantially desorbing the moisture from the coal or peat and producing superheated gases. A substantial portion of the superheated gases produced are recycled back in contact with the coal being dried. Sufficient heat is added to the recycled gases, in response to monitoring, so that the recycled gases are maintained in a substantially superheated condition throughout. This process produces a dried, substantially purified product which retains a substantial portion of its volatile content, which has an improved heat value per unit weight, and which will not absorb substantial moisture when stored or transported. 
<??>In one embodiment, the process utilizes superheated steam to initiate the drying process. In another embodiment, that minor portion of the superhreated gases in excess of the original volume not being recycled are recovered, and the fuel content thereof is used to provide energy for reheating the gases being recycled. In yet another embodiment, the processes are maintained at low pressures of under approximately 50 inches water column pressure. 
<??>The process and apparatus provided also removes a substantial portion of the impurities such as sulfur, from the low rank coals and peat. The dried product may be cooled, and the impurities may be separated therefrom.

Title: Scabbard mounted knife blade sharpener which functions in one direction of knife movement only
Inventor: PETROFF CVETAN
IPC: B24B/
Filed: 1990-08-14
Abstract: A blade sharpener having a sharpening mechanism (11) which functions to sharpen a blade engaging that mechanism (11) and being moved longitudinally relative thereto. The sharpener also includes sharpening defeating means (20) which, when operative, at least inhibits and possibly prevents sharpening of a blade by the sharpening mechanism (11) when that blade is moved longitudinally through the sharpener in one direction. The defeating means (20) is responsive to blade movement so as to adopt an operative condition when the blade is moved in the aforementioned one direction, and to adopt an inoperative condition when the blade is moved through the sharpener in the opposite direction. The defeating means (20) includes a blade engaging member (21) such as a roller, and in the operative condition that roller (21) engages and presses against the cutting edge of the blade so as to impose a force on the blade which acts counter to the force causing the blade to engage the sharpening mechanism (11). The counter force therefore tends to push the blade out of contact with the sharpening mechanism (11). The roller (21) does not engage the blade, or at least does not apply the counter force, when the defeating means (20) is in the inoperative condition. An anti-bottoming groove (23) is provided around the circumferential surface of the roller (21) to provide a location for the cutting edge of the knife blade and that groove (23) is formed to avoid contact between the actual cutting edge of the blade and the base of the groove (23).

Title: Telephone subset with line switch control circuit
Inventor: FOX RONALD CHRISTOPHER SHAW
IPC: H04M1/31
Filed: 1992-08-27
Abstract: A line switch control circuit for a telephone subset comprising a line switch (2), a hook switch mode detector (TR4), a voltage sensing circuit (TR5) having at least two inputs (D and F), and a dialler chip (3) having a CMOS push-pull pulse output (DP). The circuit ensures that when the subset is in the on-hook mode, on the one hand, an appropriate level of current is drawn from the exchange line (L1, L2) to energise the dialler chip (3), and on the other hand, the line switch (2) remains non-conducting during on-hook mode. In the off-hook mode, the circuit renders the line switch non-conducting during breaks in dialling signals as well as during flashes by diverting current from the line switch into the pulse output (D) of the dialler chip. <IMAGE>

Title: Multi-axial press fabric, for the press section of a paper machine, comprising fibre batt material needled into one of the plies and through the second base fabric
Inventor: YOOK STEVEN S
IPC: D21F7/08
Filed: 1998-10-06
Abstract: An on-machine-seamable multi-axial press fabric, for the press section of a paper machine, is made from a first base fabric 22 assembled by spirally winding a fabric strip in a plurality of contiguous turns, each of which abuts against and is attached to those adjacent thereto.  The resulting endless base fabric layer is flattened to produce first and second fabric plies 40, 42 joined to one another at folds at their widthwise edges 36.  Crosswise yarns are removed from each turn of the fabric strip at the folds at the widthwise edges to produce unbound sections 44 of lengthwise yarns 26.  The press fabric includes a second base fabric 52 comprising lengthwise and crosswise yarns, the lengthwise yarns 56 forming seaming loops 60 along two widthwise edges of fabric 52.  Fabric 52 has a length, exclusive of the loops, equal to the first fabric ply and the second fabric ply of the first base fabric.  Fabric 52 is disposed between ply 40 and 42, loops 60 extending outwardly between the unbound sections 44.  At least one layer of staple fibre batt material 66 is needled into one of the plies 40, 42 and through base fabric 52 to the other of the first and second fabric plies.  The press fabric is joined into endless form during installation on a paper machine by directing a pintle 62 through the passage formed by the interdigitation of the seaming loops 60 at the two widthwise edges 36.
