Abstract: A vehicle braking system bias adjuster which includes a brake bias adjustment knob assembly which enables the driver of the vehicle to quickly and easily set, adjust, and visually and quickly determine the relative front to rear (or right front to left front) brake bias or brake bias setting of the vehicle before and while driving the vehicle. The brake bias adjustment knob assembly visually indicates the exact amount of brake bias, or if there is no bias at all. The ratio is expressed in numbers to enable the driver to reset the brake bias to a known value of ratio as needed for track conditions and vehicle weight changes. The value in numbers is reproducible. The present disclosure also provides a method and apparatus for retrofitting an existing vehicle with a brake bias adjustment knob assembly which enables the driver of the vehicle to quickly and easily set, adjust, and visually determine the relative brake bias or brake bias setting (i.e.
Abstract: A method and cementing composition for sealing a subterranean zone penetrated by a well bore, wherein the cementing composition comprises a mixture of cementitious material, acrylonitrile butadiene styrene (ABS), and sufficient water to form a slurry.
Abstract: A speed indicator for bicycles for indicating the shifting action of the bicycle and a speed sign at each state of shift includes a driving wheel driven by a takeup reel of a shifting device, a resilient strip driven by the driving wheel, and a track along which the resilient strip may displace. When the resilient strip displaces along the track, a shift sign pre-formed on the resilient strip may be shown through an indicating element provided on the track. The resilient strip may be adapted for use in vertically or horizontally oriented tracks of any construction, and their assembly is easy. The driving wheel further includes a compensation mechanism for ensuring clear indication of the indicated sign on the resilient strip.

Abstract: The permeability of a subterranean reservoir can be more easily controlled by first injecting a crosslinking agent solution and then subsequently injecting a scleroglucan solution to thereby form, in situ, crosslinked scleroglucan gel. This reverse order of injection allows for a more homogeneous gel propagation without substantial risk of plugging.

Abstract: Tamper proof apparatus for verification that a critical temperature has been reached or exceeded includes a permanently sealed casing and cap containing a thermal element connected to a rotatable cam having a temperature indicator extending outwardly therefrom adapted to rest under a transparent window in the cap when critical temperature has been reached. Maximum and minimum temperature stops on the cap prevent movement of the indicator beyond preselected positions. An opening through the cap engages a removable shipping pin cooperating with either the maximum or minimum temperature stop to prevent movement of the indicator during shipment or storage. A locking spring connected to the cap traverses the lateral surface of the cam until the spring engages a shoulder formed in the cam. The shoulder and spring have, respectively, a first spur and a second spur that engage in permanently locked position when a critical temperature has been reached.
