Title: Fuel filler pipe seal
Inventor: BOEHMER DENNIS A
IPC: B60K15/04
Filed: 1987-06-05
Granted: 1995-02-21
Abstract: A fuel filler pipe seal includes upper and lower portions and a sealing lip positioned at the juncture of the upper and lower portions to engage an outer surface of a fuel nozzle and prevent the escape into the atmosphere of fuel fumes during a fueling operation.  The lip lies in a plane which intersects a groove formed in an outer surface of the seal to receive a seat formed on a mounting bracket mounted in an upper end of the filler pipe, and the upper portion of the seal has an umbrella valve formed integrally with it which covers a vent opening in the bracket and is preloaded to release at a predetermined pressure.  By positioning the sealing lip adjacent the seat-receiving groove a better seal with a fuel nozzle is formed, premature release of the umbrella valve is avoided, and damage to the seal when the nozzle is thrust into the filler pipe is minimized.

Title: Power control system
Inventor: CAPEWELL DENNIS
IPC: H02M5/293
Filed: 1987-08-19
Granted: 1992-06-30
Abstract: ABSTRACT OF THE DISCLOSURE          A power control system for gas discharge lamps and other loads.  According to a preferred em-bodiment, the system includes a main divertor in se-ries or parallel with the load, and a variable diver-tor, which includes a controllably conductive device controlled by a control circuit, the variable divertor being selectively inserted in series with the load during each half cycle of the output voltage signal. The system obtains an improved load voltage waveform giving superior performance under reduced power output conditions.  This system can be applied to a fluores-cent lighting circuit having a plurality of conven-tional ballasts, achieving a dimming ratio of greater than 4 to 1, and can also be applied to other gas discharge lamp circuits, including high intensity discharge lamp circuits, to incandescent lamps, and to motors such as fan motors.  It can further be applied to control the power supplied to solid-state switching units, including those having capacitive inputs.  The system produces a waveform having no sharp voltage changes, and thus virtually no audible noise emanates from the load.  Radiated and conducted EMI are signif-icantly lower than with existing controls.  The advan-tageous waveform is generated while maintaining an efficiency greater than about 95 percent.

Title: Encoding method for t1 line format for ccitt 32k bit per second adpcm and 64k bits per second clear channel transmission
Inventor: BLONDEAU ERNEST E JR
IPC: H04J3/12
Filed: 1987-08-27
Granted: 1992-05-26
Abstract: AN ENCODING METHOD FOR Tl LINE FORMAT FOR CCITT 32K        CLEAR CHANNEL TRANSMISSION ABSTRACT OF THE INVENTION The present method is an encoding scheme for suppressing excessive amount of zeroes transmitted via a Tl line facility.  Clear channel transmission capability is provided by this scheme for 32 kb/s or 64 kb/s transmission channels.  This scheme provides the proper zero bit suppression for alternating mark inversion signaling (AMI).  A proper AMI signal contains no more then 15 consecutive zero bit positions.  In addition to meeting the AMI signaling standards, this scheme does not induce any violations of VMR (violation monitor and removal) equipment. Thus, this scheme is transparent to existing line equipment and error monitoring equipment,  This scheme provides both a necessary and sufficient method for achieving the AMI signaling requirements during clear channel signaling.

Title: Optical signal control method and apparatus
Inventor: WALKER NIGEL G
IPC: G02F1/01
Filed: 1988-04-08
Granted: 1992-07-14
Abstract: ABSTRACT OPTICAL SIGNAL CONTROL METHOD AND APPARATUS Apparatus for processing one or more optical signals to produce a desired polarisation transformation on a Poincaré sphere has particular application in a receiver for a coherent communication system.  One or more birefringent elements 11 receive a polarised optical signal from a local oscillator 12, and vary the state of polarisation of the local optical signal in order to match it to a received optical signal from a remote source on a line 13.  The transformed local signal is fed on a line 14 to a directional coupler 15 which compares the local and remote optical signals.  A receiver 16 extracts data by interference between the two signals in the directional coupler 15, and feeds data out at a line 17.  A level detector 18 detects the level of the output signal 17 and supplies a feed-back signal to a polarisation controller 19, which controls the birefringent element or elements 11.     The birefringent device 11 is adapted to provide a variable rotation on a Poincaré sphere about an axis of rotation which itself may be varied in direction.  The control means 19 varies the amount of rotation on the Poincaré sphere produced by the birefringent device, and varies the direction of the axis about which the rotation takes place, so as to achieve the desired polarisation transformation.     A preferred form of the birefringent device 11 comprises a waveguide of electro-optic material, and means for producing in the electro-optic material an electric field of variable strength and variable orientation whereby required polarisation transformation can take place.  Preferably the electro-optic material is lithium niobate.

Abstract: METHOD FOR PRODUCING RED PHOSPHORUS FLAME RETARDANT        AND NONFLAMMABLE RESINOUS COMPOSITION     ABSTRACT OF THE DISCLOSURE      Red phosphorus flame retardants for synthetic resin are produced by a method comprising the steps of heating yellow phosphorus at temperatures of 250 to 600 °C to effect a partial conversion of yellow phosphorus to red phosphorus; removing unconverted yellow phosphorus; and coating particles of the resulting red phosphorus with at least one of thermosetting resin and metal hydroxide.  The thus obtained red phosphorus flame retardants are very stable because of significantly improved heat resistance, water resistance and weatherability and thus can provide nonflammable resinous compositions which can be used for long period of time.  The nonflammable composition consists essentially of 100 parts by weight of polyolefine resin, 20 to 200 parts by weight of hydrated inorganic filler and 0.1 to 30 parts by weight of the coated red phosphorus flame retardant.

Abstract: ABSTRACT OF THE DISCLOSURE         A grass cutting assembly for a rotary lawn mower having flexible resilient blades replaceably mounted on a rotor disc.  Each elongated blade has an elongated inner end portion and a flat outer cutting portion which is twisted at 90° to a flat mid portion.  The lower surface of the rotary disc has a radial blade insertion groove which leads to a blade receiving opening which extends radially through each thicker blade holder portion which projects downwardly along the outer periphery of the disc.  Each blade receiving opening has a vertically oriented narrow cylindrical portion adjacent the inner face whereby the blade rotates 90°  as it is inserted outwardly to a cutting position wherein the enlarged inner end abuts against the inner face of the blade holder portion, the mid portion is held in a vertical orientation and the outer cutting portion which projects beyond the outer periphery of the disc is held in a horizontal orientation.  The flat outer cutting portion is sufficiently rigid to efficiently cut the grass, while the vertically oriented mid portion flexes sufficiently when an obstacle is encountered to prevent serious injury, as well as to prevent block shearing.
