Patent number: 5088565Abstract: A vibratory pile driver having means for clamping onto a pile or similar structure to be driven or extracted substantially linearly, e.g. vertically, includes a hydraulic gear motor having two oppositely rotatable shafts and a pair of semicircular weights aligned in the same vertical plane. Each weight is rotatably secured to a shaft parallel to the motor shafts. Means, in the form of drive and driven pulleys, sprockets or the like connected by toothed timing belts, chains or the like, respectively, are provided for driving the weights from the motor shafts. Since the gears of the hydraulic gear motor operate in synchronization, the weights are driven synchronously to provide substantially linear, e.g. vertical, forces. Such an arrangement combines the synchronizing gears and the power source and makes it possible to eliminate relatively large gears, to use larger diameter weights and to achieve, under certain designs, a smaller overall machine width adjacent the pile to be driven.Type: GrantFiled: March 23, 1990Date of Patent: February 18, 1992Assignee: J & M Hydraulic Systems, Inc.Inventor: Kingsley S.

Patent number: 5087362Abstract: A flume distribution system includes a distributor having a stationary lower portion and a removable upper portion. The lower portion defines a duct which is in fluid communication with a flume and at least one underdrain lateral. The lower portion also includes an apertured end wall which abuts one of the underdrain laterals at a lateral inlet, and a stop is disposed within the duct and spaced from the end wall. The duct receives a removable orifice plate which is adapted to pivot between a slant inactive position abutting the stop and an upright active position restricting the aperture in the end wall. During backwash operations, water is introduced to the flume and enters each duct in the lower portion of the distributor, and the pressure of the incoming water causes the orifice plate to pivot from the slant position to the upright position, reducing the cross-sectional area of the aperture in the end wall and thereby regulating the velocity of backwash flow from the flume into the lateral inlet.Type: GrantFiled: July 26, 1991Date of Patent: February 11, 1992Assignee: F.B.

Patent number: 5084618Abstract: Autofocus method and apparatus capable of quickly detecting the focal point in an electron microscope in spite of the magnetic aftereffects of the ferromagnetic substance forming the objective lens. The autofocus method is initiated by causing the electron beam emitted from the microscope to hit a specimen at a first angle. Under this condition, the excitation current fed to the objective lens is continuously varied between values. At the same time, a video signal obtained from the resulting projected image is sampled at fixed intervals to obtain a first set of data. Then, the beam is caused to hit the specimen at a second angle. Under this condition, the excitation current fed to the objective lens is continuously varied between values. Simultaneously, a video signal produced from the resulting projected image is sampled at fixed intervals to obtain a second set of data. These two sets of data are compared to find the focal point.Type: GrantFiled: November 6, 1990Date of Patent: January 28, 1992Assignee: Jeol Ltd.Inventor: Takashi Ito

Patent number: 5080062Abstract: A method for operating a drive unit comprised of an internal combustion engine having a hydraulic aggregate group connected to it. The amount of fuel supplied to the engine in the upper idling speed range is limited by a proportionally acting speed regulator. The power consumption of the hydraulic aggregate group is reduced by a maximum load regulator when the engine is overloaded. Theretofore the hydraulic aggregate group is adjusted toward a lower power consumption after the engine speed drops below an arbitrarily rated RPM which is monitored by the maximum load regulator. In order to facilitate a variable power limitation without the use of a hydraulic power limiter, the working RPM of the maximum load regulation is set at an arbitrary value corresponding to a desired power output between the nominal speed of the engine and the upper idling speed of the engine.Type: GrantFiled: April 30, 1991Date of Patent: January 14, 1992Assignee: Linde AktiengesellschaftInventor: Hilmar Strenzke
