Title: Device for conversion of liquid fuel into fuel vapor and microscopic liquid droplets with electronic fuel injector control
Inventor: BIRCH DESMOND A
IPC: F02M31/18
Filed: 1993-10-01
Abstract: A device converts combustible liquid fuel into converted fuel having a smaller proportion of vapor and a larger proportion of microscopic fuel droplets and mixes the converted fuel with air to convert more converted fuel to vapor. A vacuum chamber (22) has a cylindrical housing wall (16) with at least one fuel inlet (28) therein and a fuel outlet (86) offset from the inlet (28). An eccentrically mounted cylindrical rotor (34) is rotatably mounted within the housing wall (16) and has one or more radial slots with a rectangular vane (76) slidably received in each slot. Converted fuel from the outlet (86) and air are supplied to a large mix-ing chamber to slow the air and allow for thorough mixing with the converted fuel. An electronic fuel management control mo-dule (EFM) provides an output signal to the fuel metering device to control the flow of the fuel in the convertor (10). An electron-ic fuel injector control has a rotor shaft (104) to provide first periodic signal pulses responsive to its angular rotational position. A sensor (116) provides second periodic signal pulses responsive to the desired angular position of the engine crankshaft (112). An electric motor (66) connected to the rotor shaft (104), when running, provides a blocking signal to the engine sensor electronics (120) to block the signal pulses from the fuel conversion signal device so that the fuel injectors (28) are activated only in response to the crankshaft pulses.

Title: Charge regulator for electronic device and associated method
Inventor: KAMKE JAMES F
IPC: H02J7/00
Filed: 1994-08-23
Abstract: An electronic device, such as a radiotelephone, is connectable to a variable-level power source (106). The electronic device includes a rechargeable power source (188) which is repowered responsive to application of operative power generated by the variable-leevel power source (106). The electronic device provides a constant charge current regulator (168) for converting operative power of a constant voltage into operative power of a constant current to be applied to the rechargeable power source (188) to recharge the rechargeable power source (188).  The constant charge current regulator (168) is made of a series connected diode (176) and resistor pair (172).  According to a further aspect of the invention, when the rechargeable power source becomes fully recharged, application of the operative power can be reduced by switching (206).

Title: Method and apparatus for producing randomly variegated multiple strand yarn and yarn and fabric made by said method
Inventor: MCNEILL WILLIAM A
IPC: D02G3/34
Filed: 1995-08-28
Abstract: A method and apparatus for producing randomly variegated multiple strand yarn in twisting together two or more yarns at a plurality of yarn twisting stations.  At each station a pneumatic twisting head is disposed in which randomly turbulent air currents are created in a chamber in the twisting head by compressed air flowing into the chamber from a manifold through bores in the twisting head, thereby randomly twisting together two or more yarns in the chamber. The yarns which have been twisted together are taken up over a plurality of traversing drums commonly mounted on a shaft which is driven by an alternating electric current motor controlled by a control device which operates to start and restart the motor on a predetermined cycle including a variation of the electrical input sufficient to result in randomly unpredictable inertia resistance of the traversing drums to rotational speed variation, thereby creating randomly unpredictable take-up of the yarns to produce non-uniform random twist in the yarns.        The yarn produced has various lengths of opposite twist with varying degrees of twist and sections of no twist, and the fabric produced with the yarn is randomly variegated with no repeating pattern.

Inventor: GOSTINE MARK L
IPC: A47C20/02
Filed: 1996-03-21
Abstract: A therapeutic pillow for relieving various types of low back pain. The pillow comprises two hemispherical end sections joined by an elongated midsection. The midsection is a substantially flat lumbar support portion with sloping surfaces extending to each end section, to provide a pillow that is substantially concave in shape. In use, when sleeping on one's side, the pillow is placed generally transverse to the length of the body under the side. The midsection provides support and alignment for the lumbar spine, thereby relieving pain associated with sagging of the spine. Further, by placing one hemisphere close to the back or hip, the pillow will wrap around the hip area and place pressure on the sacro-iliac joint, for pain relief in that particular area of the body. The pillow can also be placed transverse to the body under the stomach when one sleeps on his or her stomach, again to support and align the lumbar spine. The hemispherical end pads also serve to confine the sleeping person on the pillow and keep the person from rolling out of the pillow.
