Title: Two-wheeled running gear for track-guided vehicles
Inventor: KROUZILEK ROLF
IPC: B61F5/46
Filed: 1996-10-10
Abstract: In a two-wheeled bogie for track-guided vehicles with a traction-supported steering device and with a wheel mount, both wheels (4, 4') are mounted on the common wheel mount (3) on a notional connecting line extending perpendicular to the wheel circumference and lying between the individual wheel axles; the wheels are arranged substantially parallel to each other and at a substantially constant distance from one another. The wheel mount (3) has two vertical pivoting axles (2, 2") outside the wheel contact points which can be used alternately. The vertical pivoting axles can be moved in the horizontal plane and locked in accordance with the curvature of the curved track, and the wheel mount (3) can be steered about the axle which has not been moved and is locked in an intermediate middle position.

Patent CA-2239240-A1 (CA)
Inventor: THOMAS RICKEY J
IPC: B23B51/02
Filed: 1998-05-29
Abstract: Significantly improved resistance to breaking while drilling in metal can be realized in twist drill bits having a web thickness taper which is about twice the web thickness taper specified in Standards and in common use in the industry. This creates much shallower flutes and flies in the face of conventional wisdom in the art which holds that the web taper rate should be low to maximize the amount of flute volume available to convey chips and sawdust out of the hole. A flute length of about 1/2" less than the flute lengths specified by the Standards makes it possible to have such a large taper rate but still control variations in tolerances for the flute length. It also provides a marking zone for placing size indicia on the drill bit shank outside the portion which is gripped by the chuck jaws of a power drill. The use of the new web taper rate, in conjunction with modifications to the tip geometry of a self-centering drill bit with pilot tip, produces a drill bit optimized both for metal and wood drilling which is strong enough to withstand the forces exerted on the bit while drilling in metal using a hand-held power drill, yet which need not be retracted from a 2 X 4 to clear sawdust prior to drilling a hole completely through the thickness of the wood.

Abstract: A stuffing box gland 20 that cooperates with packing 38 positioned within a stuffing box 18 to seal between a stuffing box housing 42 and a moveable polished rod 27 of an oilfield pump assembly 10. A lower end of a gland housing 46 forms a flange 50 extending radially outward from the gland housing 46 that is adapted for transmitting a variable compressive force to the packing 38, within the stuffing box 18. A plurality of attachment members 52 are utilized for interconnecting the gland housing flange 50 and the stuffing box housing flange 51 and may be adjusted to vary the compressive force exerted by the lower end 48 of the gland housing 46 on the packing 38. A sleeve 56 surrounds the polished rod 27 and includes a lower end 58 that seals with an annular seat 54. A pair of semi-cylindrical absorbent pads 100 and 110 are positioned radially inward of the fluid impermeable sleeve 56 and cooperate with a pair of absorbent wicks 116 and 118 for transmitting a lubricant from a fluid reservoir 64 to the absorbent pads 100 and 11, thereby lubricating the polished rod 27.

Title: Flow meter within caustic fluids having non-contaminating body
Inventor: ENGLUND DIANE L
IPC: G01F1/44
Filed: 1997-01-22
Abstract: A non-contaminating flow meter having an isolation member. The flow meter includes two pressure sensor transducers (42, 44), located on opposite sides of a restriction (35) in a conduit. Each of the pressure transducers is isolated by an isolation member (38) from exposure to fluids flowing through the conduit. The flow meter may be placed in line within a fluid flow line carrying corrosive materials. The square root of the difference in pressure between the two pressure sensors is calculated to determine the rate of low within the fluid line. The flow meter compensates for changes in temperature within the fluid flow line and activates an alarm if the pressure of flow rate within the fluid flow line exceeds or falls below a threshold level.

Title: Bake hardenable vanadium containing steel
Inventor: SPEER JOHN G
IPC: C22C38/00
Filed: 1996-05-01
Abstract: Rolled articles such as hot rolled or cold rolled and annealed sheet and/or strip include effective amounts of vanadium in low carbon steels to produce an improved bake hardenable product especially adapted for automotive use. The use of vanadium in the alloy steel chemistry controls bake hardenability, permits solution annealing at lower temperatures in its manufacturing sequence and specifies a composition range which is more easily cast within desired limits and causes less variation in final mechanical properties. Controlling the vanadium to carbon ratio to maintain a value of about 10 or greater also improves aging resistance.

Title: Wellhead production blowout preventer ram
Inventor: FARQUHARSON KEITH D
IPC: E21B33/06
Filed: 1999-02-02
Abstract: The ram comprises an L-shaped bottom retainer plate, an L-shaped seal element and a top retainer plate having an L-shaped inner surface. The front portions of the inner surfaces of the retainer plates are parallel and acutely angled relative to the longitudinal axis of the ram bore. Thus the top retainer plate is tapered rearwardly. The seal element protrudes forwardly of the retainer plate which, in turn, protrudes forwardly of the bottom retainer plate. When the rams close, the top retainer plates are driven rearwardly and act as wedges to compress the seal elements both downwardly and rearwardly. The L-shaped design also leads to minimization of canting of the plates. A groove is provided, extending longitudinally along the base of the bottom retainer plate, for draining steam condensate from behind the ram.

Title: Wireless atm metropolitan area network
Inventor: BEN-EFRAIM GIDEON
IPC: H04L12/56
Filed: 1997-09-04
Abstract: The present invention provides an efficient point-to-multipoint microwave ATM  network including a base station (BS 205) broadcasting a continuous transmission with a sector antenna (200). The system uses time division multiplex (TDM) for downstream transmission and time division multiple access (TDMA) for upstream transmission. The downstream transmission consists of ATM  cells encapsulated in MAC protocol data units (PDUs) for forward error correction (FEC) and synchronization. Small Subscriber Terminals (STs),including Subscriber Radio Units (SRUs 202), receive the broadcast and pass it to a Subscriber Access System (SAS 204) that drops the ATM cells addressed only to them. To allow strong FEC protection and to maintain the same symbol rate as the downstream transmission without sacrificing bandwidth, a modified trellis code modulation technique, which incorporates Reed Solomon coding, is used during upstream transmission.
