Title: Polymer cage for a tapered roller bearing
Inventor: FAIGLEY C
IPC: F16C19/20
Filed: 1981-03-20
Abstract: A molded polymer cage (C) for a tapered roller bearing has end rings (20, 22) that are located beyond and extend across the large and small ends of the tapered rollers (6) for the bearing and bridges (24) that extend between and are formed integral with the two rings so as to form pockets (26) in which the tapered rollers are confined. The cage not only spaces the rollers at even intervals between the cup (4) and cone (2), but it further holds the rollers (6) around the cone when the cone is separated from the cup. To this end, the bridges (24) of the cage (C) are located entirely beyond the pitch circle for the rollers (6) so as to leave adequate space for the introduction and circulation of a lubricant, and each bridge along each of its side faces has two beveled surfaces (34, 36), namely, an inner surface (34) and an outer surface (36), both of which are planar. The outer surface (36) is located further from the cone and pitch circle than the inner surface (34) and is further disposed at a lesser angle with respect to the pitch circle. As a consequence, the outer surfaces (36) of the bridges (34) lap sufficiently over the rollers (6) to provide the cage (C) with excellent retention characteristics.

Title: Electronic engine synchronization and timing apparatus
Inventor: BOLINGER R
IPC: F02D45/00
Filed: 1981-07-27
Abstract: Electronic engine synchronization and timing apparatus (10) for use in controlling fuel injection and/or spark ignition for an internal combustion engine. An engine crankshaft (11) rotates a rotary body (12) having a plurality of radial projections (19-22), and a single crankshaft reluctance sensor (23) is utilized to provide pulses (24) in response to the passage of these projections and thereby provide a signal (24) related to crankshaft position. An engine camshaft (13) rotates a rotary body (14) with radial projections (15, 16) at half of the crankshaft speed, and a pair of camshaft sensors (17, 18) provide signals (25, 26) in response to the passage of the camshaft projections which are indicative of the rotational position of the camshaft. The signals (24, 25, 26) provided by the crankshaft and camshaft sensors are received by circuitry (30-35) which provides a crankshaft reference signal (27) having transitions of alternate predetermined polarities at specific rotational positions of the crankshaft and also provides cylinder identification signals (60-63) which are indicative of the angular rotational position of the camshaft rotary body. These signals (27, 60-63) are then utilized by conventional electronic fuel injection and/or spark ignition control apparatus to control engine cylinder operations in the proper sequence and at the proper time.

Patent WO-8203146-A1 (WO)
Title: Error correction arrangement for imagers
Inventor: MEISE WILLIAM HARRY
IPC: H04N5/217
Filed: 1982-03-08
Abstract: Two or more CCD imagers (12, 14), which have random defects are optically coupled to form a single image. The CCD's are in registry. Because of the random nature of the location of the defects, the defective photosensors of one imager (12) are aligned with good photosensors of another (14). Memories (34, 36) keep track of which locations of which CCD are defective. The imagers (12, 14) are operated synchronously and the signals from good photosensor locations are summed for improved signal-to-noise ratio. When a location is addressed at which one imager (12) has a defective photosensor, the respective memory (34) decouples it from the good photosensor of the other imager (14). The signal level is restored for that location by increasing the gain of a preamp (46) by the correct amount. If the imagers (12, 14) are made from the same mask, they may have almost identically corresponding defective photosensors. Then one imager (12) is mounted upside-down relative to the other (14) and scanned backwards so the defects do not coincide.

Title: Control mode switching circuit
Inventor: DOLLERSCHELL JOHN O
IPC: B30B15/16
Filed: 1983-08-05
Abstract: A "mode switch" (45) is used for smoothly switching a servovalve controlled device such as an SMC press (10), in particular, from control under one parameter to control by another. The mode switch (45) provides a very smooth transfer of control from displacement control (47) between two relatively movable parts (20, 23) to force control (46) to provide for controlling the force exerted by actuators acting between the two parts (20, 23). The mode switch (45) electronically tracks the signals so that when the switching (64, 65) is made the signals are precisely equal to prevent abrupt changes in the control signals. This smooth transfer is achieved even under active control, that is when both control signals are changing in value.

Title: Process and apparatus for handling waste from oil well operations
Inventor: SIMON JULES A
IPC: C02F11/123
Filed: 1984-06-28
Abstract: A process and apparatus for separating drilling mud and waste materials into pure water and a concentrated solid waste phase which is easily handled and disposed of. The process and apparatus provide for adjusting the pH of the drilling mud and waste materials to be separated, mixing the thus pH adjusted mud and waste materials with a flocculating agent and allowing the solids to settle out. The solids are then removed and further dewatered to produce a relatively dry concentrated solid waste phase. If desired, the clarified water is mixed with finely divided activated charcoal to remove various impurities from the clarified water. The mixture of clarified water and charcoal are then filtered to produce a filtrate stream which is further separated to produce pure water and a liquid phase containing dissolved solids. The pure water can then be reused in the drilling process or safely discarded into the environment.

Title: Rocket-powered, air-deployed, lift-assisted booster vehicle for orbital, supraorbital and suborbital flight
Inventor: ELIAS ANTONIO LUIS
IPC: B64G1/00
Filed: 1989-03-08
Abstract: A rocket-powered, air-deployed, lift-assisted booster vehicle (ALBV) (100) is disclosed for efficiently carrying small payloads to orbital, supraorbital or suborbital altitudes and velocities. The ALBV is secured beneath a conventional carrier aircraft (200) and dropped therefrom at launch altitude and velocity, which contributes significant total energy to the ALBV's ascent trajectory. The ALBV has wings (23), which generate aerodynamic lift to assist in vehicle ascent, and tail fins (24), which perform attitude control while the vehicle is in the sensible atmosphere. After drop launch, an innovative "vertical-S" maneuver is performed using aerodynamic control, causing the ALBV (100) to ascend on a near-theoretical optimal trajectory. In the preferred embodiment, the wings (23) and tail fins (24) are jettisoned as the vehicle exits the sensible atmosphere and aerodynamic lift ceases. This invention represents a dramatic improvement over prior art approaches to orbital payload launch, as it approximately doubles the useful payload that can be carried by the booster compared to identical ground-launched vehicles.
