Abstract:
A bicycle suspension assembly having an inertia valve is described. The inertia valve moves between its closed and open positions in response to at least a portion of the bicycle suspension assembly being subjected to an upward acceleration above a predetermined threshold. For example, the predetermined upward acceleration threshold may be about 0.1-3 G's.
Abstract:
A lift for lifting motorcycles, ATV's, or any similar vehicle. The lift includes a base, an upright extending from the base, a four-bar load-transferring lifting mechanism, a lifting frame adapted to engage the vehicle, and an operator for lifting and lowering the lifting frame.
Abstract:
Magnetic field response sensors designed as passive inductor-capacitor circuits produce magnetic field responses whose harmonic frequencies correspond to states of physical properties for which the sensors measure. Power to the sensing element is acquired using Faraday induction. A radio frequency antenna produces the time varying magnetic field used for powering the sensor, as well as receiving the magnetic field response of the sensor. An interrogation architecture for discerning changes in sensor's response frequency, resistance and amplitude is integral to the method thus enabling a variety of measurements. Multiple sensors can be interrogated using this method, thus eliminating the need to have a data acquisition channel dedicated to each sensor. The method does not require the sensors to be in proximity to any form of acquisition hardware. A vast array of sensors can be used as interchangeable parts in an overall sensing system.
Abstract:
A locking wheel chock apparatus for use with tent trailers, travel trailers and boat trailers having single or dual axles. The chock apparatus functions not only to hold a trailer in position, but also to limit the rocking or rotational movement of tire and wheel combination where a tent or travel trailer is used for camping, i.e. living conditions. The chock apparatus generally comprises a pair of metal chock assemblies which are movably linked together by a screw driven mechanism for tightening and loosening that the chock assemblies about that the tread area of a single tire and wheel assembly. A first embodiment of the chock apparatus uses a shaft-like drive mechanism having a centrally located hand grip and right and left hand thread screws. Both manual and wrench assisted tightening and loosening of the chock assemblies is attainable. A second embodiment employs a drive mechanism comprising a single threaded Acme drive screw located in side two longitudinally telescoping, tube members and threadably received by two trunnions. The tubes are caused to telescope by using a common ratchet wrench to turn a hex nut provided at an end of that the drive screw. Both embodiments are capable of being reduced to a small package to facilitate storage and transportation when not in use.
Abstract:
A space-dividing wall panel system having a plurality of upright wall panels serially connected one with the other by an intermediate upright support post. The height of each wall panel is adjusted by modular panel extension assemblies which are mounted on base panels supported by lower support posts and include extension posts connected to the lower support posts so as to be arranged coaxial therewith. Spaced apart pairs of the extension posts are connectable to a cross rail at upper ends thereof which defines a downwardly extending generally U-shaped extension frame. A serially adjacent pair of extension frames shares a common extension post which is connected to both of the cross rails thereof, where the base panel and the extension panel assembly disposed thereon respectively define base and beltline raceways for workstation cabling. Additional extension posts can be inserted into the upper ends of extension posts already positioned so as to vertically extend the height of the wall panel. Removable covers are provided so as to overlie the outward faces of the base panel and the extension panels which panel covers are spaced outwardly from the outer faces of the base panel and extension frame so as to define passages therebetween. The passages permit horizontal cabling along the base raceway and the beltline raceway between adjacent wall panels while further permitting vertical routing of cabling between the base and beltline raceways within each panel.
Abstract:
Fluid being pumped by rotary piston/lobe pumps is prone to fluid cavitation particularly at the leading and trailing edges of the rotor.A rotor 10 comprises a generally cylindrical rotor hub portion 108 formed with two piston wing portions 110, 111. The piston wing portions 110, 111 are disposed transversely of the axis 13 on a substantially flat surface 112 of the hub portion 108. Extending from the surface 112 coaxially with axis 13, and disposed radially within the rotor hub portion 108, is a tubular portion 114 through which the end of shaft 15 passes when the rotary pump assembly is in an assembled state.Each piston wing portion 110, 111 is formed with a sinuous curved leading face region 113 and a sinuous curved trailing face region 115.The radially outermost (relative to the rotor axis) region of the leading face region 113 is formed with a leading curved edge part 116 and the radially outermost region of the trailing face region is formed with a trailing curved edge part 118.
Abstract:
A golf ball set-up apparatus 100 provides a tee assembly 600 which slides within a set-up tube 350 between a lower position wherein a ball advancing from a ball supply trough 410 is mounted on the tee 610 and an upper position wherein the ball is elevated to a position suitable for driving by the golfer. The tee assembly is moved between upper and lower positions by a lift arm assembly 300, which is in turn driven by a driving lever extension 250 extending from the driving lever assembly 200. Pressure of a golf club moves the driving lever assembly between an at-rest position, to a position wherein the tee assembly is fully lowered. When the tee assembly is lowered, a ball stop assembly 500 engages the column of in-coming golf balls, preventing their advancement. When the golf club is removed, a return weight assembly 450 returns the set-up apparatus to the at-rest configuration, with a movement that is damped by the air break assembly 550. With the tee assembly in the raised position, the ball stop assembly is disengaged, allowing the column of golf balls to advance.

Abstract:
Cobalt acetate solution is produced by flowing a circulating oxygen-containing stream of dilute acetic acid solution containing initially about 20% free acid through a bed of cobalt chips and adding dilute acetic acid solution and introducing additional oxygen into the circulating stream in replenishment of those reactants as the dissolution reaction proceeds.
