Abstract: A landing gear for semitrailers includes a two speed double reduction  gear  assembly  having  fewer, smaller,  and simpler parts,  resulting  in a compact double reduction gear assembly housed in a relatively small gear box or entirely within one of the landing gear legs, which is a cost efficient landing gear unit with a unique clutch-shifting mechanism to provide for shifting from one ratio to another.  The double reduction gear assembly is disposed on and about in-line input and output shafts further resulting in an easy to crank and shift landing gear unit capable of achieving standard  crank  handle  turn to  vertical  leg  travel distance ratios.  The low gear or low speed ratio of the landing gear unit can be varied within a broad range during  manufacture,  if  desired,  generally  without increasing the overall size or complexity of the two speed double reduction gear assembly.  The landing gear can further include a universal mounting feature and is durable and simple to use.

Title: Stock dividing method and apparatus for gear manufacturing machines
Inventor: LOEHRKE JOHN M
IPC: G05B19/18
Filed: 1991-04-24
Granted: 1996-09-03
Abstract: Method and apparatus for stock dividing gear-shaped workpieces mounted on the work spindle of a gear-finishing machine tool. A work spindle encoder provides instantaneous angular position information when the surface of leading and trailing flanks of the workpiece teeth are sensed by a probe. This instantaneous position information is used to generate two sets of measured error values which relate, respectively, to the leading and trailing flanks and which are indicative of the differences between the sensed surfaces and the desired surfaces of a correctly-sized gear. These sets of error values are analyzed using fourier transform techniques to generate a first harmonic for each set and a set of modified error values for each leading and trailing flank corresponding to each respective first harmonic. The largest and smallest modified error values of each set are used to simulate the opposite sides of the largest and smallest "effective" (as different from "actual") tooth spaces of the unfinished workpiece, and these effective spacings are compared to the desired correctly-sized tooth space of a finished gear to generate a correction value for adjusting the angular position of the workpiece relative to the finishing tool prior to initiation of the finishing process. In the preferred embodiment, a non-contact probe is used for sensing the flanks of the workpiece so that the entire stock division procedure takes only a relatively few seconds.

Title: Guidewire controls for a manned, material handling vehicle
Inventor: HELLMANN CHRISTOPHER J
IPC: G05D1/02
Filed: 1994-02-25
Granted: 2000-01-25
Abstract: The present invention features a universal, manned, material handling vehicle. The material handling vehicle is capable of operating in a manned mode, a wire guidance mode, and a rail guidance mode. This manned material handling vehicle contains a steering management control system having a logic program which allows the vehicle to adapt itself to different wire control systems. That is, particular parameters, frequency and amplitude of the underlying wire guidance system can be determined. In this manner, the manned vehicle is universally adaptive to a wide variety of wire guidance systems. When in manned operation mode, should the vehicle receive a wire guidance signal, the system controller will be duly informed. When in wire guidance operation mode, should the vehicle lose or fail to receive a clear wire guidance signal appropriate to guide on, it will automatically revert to the manned operation mode. The steering management control system also monitors the weight and height of the vehicle s load. This steering management control system receives signals from the steering tiller, as well as from the guidewire embedded in the floor of the material storage facility.

Abstract: A manually operated leveling system for a vehicle such as a recreational vehicle or the like in-cludes three jacks in the form of hydraulic cylinders mounted to the vehicle frame. A shoe is mounted to the piston rod of each jack. Two jacks are located adjacent the rear of the vehicle and one jack is located adjacent the front of the vehicle. A series of manually actuated switches, oriented in a diamond pattern, are located within the interior of the vehicle, and are interconnect-ed with the jacks to provide selective extension of the jacks in order to adjust the attitude of the vehicle relative to level. A cross-check level or bullseye level is mounted within the interior of the vehicle for viewing by the operator to determine the attitude of the vehicle relative to level. A series of control valves are inter-posed between the jacks and the switches for controlling extension and retraction of the jacks in response to manual operation of the switches. A unique jack con-struction allows the jacks to be mounted to the frame in any satisfactory location while preventing interference of the jack springs with portions of the vehicle's under-carriage adjacent the frame.

Granted: 2002-06-25
Abstract: A method of inspecting an abnormality occurring inside a pipe to be inspected and an apparatus for practicing the method, includes the steps of transmitting an electric wave having a predetermined frequency from an antenna of a transmitter located at a predetermined position inside the pipe, receiving the transmitted electric wave by an antenna of a receiver located at a predetermined position inside the pipe, and discriminating the characteristic of the received electric wave. The characteristic of the received electric wave is the intensity of the electric wave, and an attenuation amount is detected in the first example. On the other hand, the characteristic of the received electric wave is a time required to reflect the transmitted electric wave until it is received by the receiver, and a time interval between transmission of the electric wave and reception of the reflected electric wave is measured in the second example.
