Abstract: Embodiments of the present disclosure may include a system for returning a golf ball to a golfer playing simulated golf or hitting a golf ball towards any vertical surface or hitting it into a net or such, the system including a ball catcher tray assembly adapted to receive a golf ball after the golfer has hit the ball against an impact surface, the ball catcher tray optionally including ball catcher tray sections connected together. Embodiments may also include a golf ball launcher adapted to receive the golf ball as it rolls from the ball catcher tray assembly. Embodiments may also include a modular track system comprised of interconnected track sections, at least one of which may be connected to the golf ball launcher and may be adapted to receive the golf ball from the golf ball launcher as the ball may be propelled toward the golfer.

Abstract: Webcam systems and mount assemblies are disclosed that can dispose a camera at or near a middle of computer monitor whereby a user is viewed by the camera from a face-front position, and wherein the position of the camera is vertically and laterally manually adjustable (without tools) to facilitate a variety of positions according to need or desire. The webcam systems and mount assemblies further may be used with any of a tablet computing device, a laptop computer, a free-standing computer monitor, etc., and may be mounted to any edge or an adjacent structure while permitting disposing the camera at or near a center of the monitor.

Abstract: A multiple-loaded non-ceramic dry carrier product and method for the loading of reagent liquids, solids dissolved in liquids as solutions, suspensions, and solids heated to reduce viscosity, onto perlite, pumice, scoria, or exfoliated vermiculite or activated charcoal particles, which are used as carriers, and then dried in multiple iterations to achieve a powdered, free-flowing material for use in hydraulic fracturing processes and other uses such as environmental remediation and animal control, providing improvements in cost, carrier stability, and chemical retention properties.

Abstract: Process for internally loading liquids onto carriers and achieving time-release dry liquid concentrate. The resulting time-release dry liquid concentrates having a variety of applications, including animal attractants and repellants, down hole chemicals, flavors and fragrances of food and beverages, treatment of contaminants, fertilizers, vitamins.

Abstract: Fracturing-fluid products and a method of making up an expanded list of viable chemical carriers that improve the economic considerations and competition in the industry, improve carrier stability and chemical retention duration, and provide the most effective and safest fracturing fluid for each of the many varied conditions and varied processes which use some form of hydraulic fracturing, by loading liquids, solutions of solids dissolved in liquids, suspensions, or solids heated to reduce viscosity onto scoria, perlite, pumice, aerogels, activated alumina, fullerenes, graphite, molybdenum, magnetite, vermiculite, and activated charcoal to achieve a dry liquid concentrate (“DLC”) or slurry, for use in processes where a substance or substrate is to be expanded by a pressurized propellant and held in an expanded state by a proppant of granular solid material, including, without limitation, hydraulic fracturing for hydrocarbons, manufacturing, oil well treatment and production chemicals, biological treatment an

Abstract: A mainshaft assembly for a gearbox includes a mainshaft (44) and drive gears (31, 36) carried for rotation about the mainshaft. First and second hubs (50, 50?) are associated with respective drive gears, each hub being operable to selectively couple or uncouple with the drive gear causing it to rotate with the hub or with respect to the hub. A drive connection mechanism (42, 64, 66) associated with each hub selectively connects the hub to the mainshaft. Upon connection of the hubs to the drive gears, the drive connection operates to connect one or other of the hubs to the mainshaft when torque is applied to the mainshaft in a first direction or an opposite direction. This enables a gear ratio to be selected by reversing the torque being handled by the gearbox.

Abstract: A mainshaft assembly for a gearbox and a gearbox embodying such a mainshaft assembly are disclosed. The mainshaft assembly comprises a mainshaft (44), and several drive gears (31 . . . 36), each carried for rotation about the mainshaft, each drive gear having a different number of teeth. The assembly includes first and a second hub (50, 50?), each being associated with a respective drive gear, each hub having a dog ring (54, 54?) operable to selectively couple with the drive gear causing it to rotate with the hub or uncouple from the drive gear to allow the drive gear to rotate with respect to the hub. A respective drive connection including a cage (42) and pawls (64, 66) is associated with each hub and selectively connects the hub to the mainshaft for rotation with it or to allow rotation with respect to it when the pawls are displaced against a spring bias.

Abstract: A wireless communication device includes an antenna for wireless communication with a remote interrogator. Several embodiments are disclosed to increase the options available to designers of wireless communication devices. In some embodiments, the antenna is a quarter wavelength long with one end of the antenna being grounded to provide desired impedance matching characteristics. The position of the ground plane relative to the antenna is also varied between embodiments. The connection from a wireless communication chip to the antenna is also varied between embodiments to provide alternate structures.

Abstract: The use of a stabiliser comprising a hydrophilic polymeric chain of more than four hydrophilic monomer groups and/or having a mass greater than 300 amu, linked at one end to a hydrocarbon-soluble hydrophobic group to reduce or prevent the flocculation of systems comprising a flocculable surfactant and a liquid medium which is capable of flocculating the surfactant and in which the stabiliser is capable of existing as a micellar solution at a concentration of at least 1% by weight.

Abstract: The present invention discloses solventless composition suitable for application as a hot melt to a substrate, said composition comprising a mixture or alloy of resins, selected such that the averaged glass transition temperature (Tg) of the combined unreacted resins is greater than -30.degree. and less than +60.degree. C. The melt viscosity of the unreacted resins are selected so that the combined resin mix has a melt viscosity of from about 0.05 to 25 Poise when measured at 180.degree. C. and at a shear rate of 10,000 Hz.
