Abstract: A guide to support a shaft such as a pump pull rod (11) which is capable of both rotary and reciprocal motion. The guide prevents any misalignment of rod (11) damaging a seal, e.g. a stuffing box, held in space (24).      Guide element (18) has central portion (19) and annular flange (25). Element (18) can move laterally with respect to housing (12) and can also pivot, along with the cap (15) of the housing (12), with respect to the lower portion (14) thereof. The latter is achieved via movements of part-spherical bearing element (28) and similarly shaped faces (26, 37, 38) of housing (12). Further seals (33, 34) prevent entry of pumped fluid into chamber (13).

Title: Wireless packer/anchor setting or activation
Inventor: SONNIER JAMES A
IPC: E21B47/18
Filed: 2002-01-22
Granted: 2006-03-28
Abstract: The present invention discloses the concept of using, for the purpose of operating a well control tool such as setting a packer, slip or whipstock, wireless data signal emissions from a downhole telemetry instrument such as an MWD or LWD unit that is energized by pumped fluid flow along a surface connected tubing string. The well control tool may be one that derives operating energy in situ such as from well bore fluid pressure or batteries. Operation of the well control tool is triggered by a battery powered microprocessor that is programmed to respond to a predetermined sequence of wireless data signal emissions from the telemetry instrument. Control over the wireless data signal sequence is exercised by control over the pumped flow stream such as by starting and stopping the pump or diverting the downhole flow stream.

Title: Water heater shut off device with water pressure delay line
Inventor: DULAC LAWRENCE M
IPC: F24H9/12
Filed: 2002-02-08
Granted: 2010-09-14
Abstract: A water supply shut off system includes a water pressure delay device which delays the transmission of any apparent change in water pressure between the input and the output side of the valve to the control input of the valve. This delay allows the input and output pressures to have a chance to generally equalize without falsely tripping the device. The water supply shut off system can also include a thermal expansion/contraction device that allows thermal expansion and contraction of a fluid medium, such as water, when the shut off device is used with a device to be protected such as a hot water heater.

Abstract: Systems and methods are described for using physical buttons (15a - 15d) on a device (10) in association with a display (25) to display, access, and execute functions available through associated hardware and software.    The physical buttons (15a - 15d) are programmable, and the function of each button is displayed on an associated display (25) when the button is activated using a first type of motion, and the function of the button is performed when the button is activated using a second type of motion. This allows the display (25) to be free of unnecessary icons, too]-tips, menus, text, etc., and to be devoted to actual content unless and until a user decides to perform a function associated with the device containing the display. Increasing the available display space is especially important in the advancing art of electronics, where devices are becoming smaller and smaller, yet consumers are demanding more and more functionality.

Granted: 2009-08-04
Abstract: A recoil control mechanism for a weapon which fires a projectile which is characterised by the generation of a forward counterforce to the rearward recoil simultaneously with absorption of rearward recoil force upon initiation of propoulsion of the projectile. The forward counterforce is generated by propelling a first mass forwardly upon firing the projectile and substantially simultaneously propelling a second mass rearwardly for absorbing some of the recoil force. In one mechanism (10), the first mass may be the weapon's barrel (12) and the second mass its breach block (14).  Expaning gases (36) from detonation of propellant in cartridge (24) enter a reaction volume (28) between the barrel (12) and breech block (14). These gases drive barrel (12) forwardly against force transmission spring (16) to impose a forward counterforce on the weapon's frame (18). Substantially simultaneously recoil from detonation of cartridge (22) together with the gasses (36) in reaction volume (28) drive breech block (14) rearwardly against force absorbing spring (20).

A  mechanism (32, 56) in the cartridge automatically positions the selectively positionable member in alignment with the aperture. Preferably, a feedback mechanism (64, 66) generates a positional feedback signal of a position of the chambers of the positionable member relative to the aperture.

Abstract: A system and method for improving the accuracy of altitude determinations in an inertial navigation system. The system utilizes pressure measurements which are taken by a barometric altimeter and converted into an estimated-pressure altitude using any known pressure-to-altitude conversion. The estimated pressure altitude is then converted into a pressure correction value using a correction value generating formula that is a function of altitude. The pressure correction value is then multiplied by a pressure offset value for the barometric altimeter to generate a pressure offset error for the barometric altimeter. This pressure offset error is used in the present invention to modify the altitude estimation in order to generate an altitude determination having an improved accuracy. The present invention further determines an amount of observation noise in the barometric altimeter that is a function of pressure noise and altitude, where the altitude estimation is further modified to account for the observation noise. Thus, the system and method of the present invention improves the accuracy of altitude determinations in inertial navigation system over prior systems by directly accounting for errors in pressure measurements taken by a barometric altimeter due to offset and noise.

Abstract: A control system for a cooking appliance enables a consumer to perform a complete cooking operation regardless of whether food is placed into an oven after a preheating operation or from a cold start. In general, under circumstances wherein the consumer does not intend to allow the oven to be properly preheated prior to inserting the food to be cooked therein, an initial programming operation is followed by an additional control sequence by the user to establish a cold start cooking operation wherein the lack of preheating is automatically compensated for, preferably by causing the oven to reach a peak temperature for the oven which is well above a temperature set by the user for the overall cooking operation. After the peak temperature is reached, the oven temperature is allowed to gradually reduce to the preprogrammed cooking temperature.
