Patent number: 3946822Abstract: A tracklaying vehicle comprises first and second laterally spaced tracklaying units which are spaced apart in a travel direction from third and fourth tracklaying units which are spaced laterally from each other. A substructure which is supported on and located in between the tracklaying units includes a carrier shaft extending in the travel direction which provides a journal for rotatably mounting a cross beam which extends between one set of the tracklaying units, for example, the first and second tracklaying units. The other set of tracklaying units, the third and fourth one, are designed as steering units, and they are mounted on individual arms which are pivotally mounted on vertical pivots of the substructure and which are connected to steering devices for pivoting them about the rotatable mountings on each side of the substructure in order to shift the position of the third and fourth tracklaying units.Type: GrantFiled: December 20, 1974Date of Patent: March 30, 1976Assignee: O & K Orenstein & Koppel AktiengesellschaftInventors: Jurgen Dohse, Klaus Klucker

Patent number: 3945236Abstract: A flat metal plate is first formed into a suitable segment of a large generally spherical body. It is then properly positioned on a horizontal cradle and its edges cut vertically as if from infinity, i.e. so that they are all parallel. A cutter then traverses the pre-cut edge to form the proper contour for welding. The pre-cut edge itself forms an accurate fixed reference and cooperates with guides on the face of the curved plate to keep the axis of the milling cutter tool substantially perpendicular to the surface of the plate at the point of milling contact. When all segments are so made and then joined, the resultant generally spherical body will be within substantially closer tolerances.Type: GrantFiled: October 3, 1974Date of Patent: March 23, 1976Assignee: C-R-O Engineering Co., Inc.Inventor: Harry Hooper

Patent number: 3943478Abstract: An adjustable bimetal snap disc thermostat is disclosed in which a leaf spring acts at its center to apply a force to a bimetal snap disc to alter the operating temperature thereof. The force of the spring applied to the disc is adjusted by an operating member which simultaneously moves both ends of the spring with respect to its center. The operating member is located on the side of the thermostat switch remote from the disc and is provided with projections which extend around opposite sides of the switch to the spring. With this structural arrangement, small adjustment travels are required for a given adjusting spring and the thermostat is constructed in a compact manner, which is symmetrical about the center axis of the device.Type: GrantFiled: December 18, 1974Date of Patent: March 9, 1976Assignee: Therm-O-Disc IncorporatedInventor: Donald E.

Patent number: 3943480Abstract: A multiple bimetallic snap disc thermostat is disclosed in which two series connected switch mechanisms are respectively operated by two concentric bimetal snap discs having the same diameter. One snap disc is thermally automatic in operation to open and close its associated switch upon reaching its calibration temperatures. The outer disc is a one-shot disc which does not automatically reset and cannot be manually reset after operation. The two discs are mounted in a single, disc retaining cup, and are spaced by a ring positioned between their peripheries. This allows said discs to be formed of the same size and provides easy mounting. A single fixed contact member provides the fixed contact for both switches. The contacts of the switch associated with the automatic disc are capable of repeated operation whereas the contacts of the switch associated with the one-shot disc are not structured for repeated cycling.Type: GrantFiled: December 18, 1974Date of Patent: March 9, 1976Assignee: Therm-O-Disc IncorporatedInventor: Donald J. Schmitt

Patent number: 3940646Abstract: A single-phase induction motor provides a plurality of serially connected main winding coils and a plurality of corresponding auxiliary winding coils each spaced in quadrature from a corresponding main winding coil. Each auxiliary winding coil is energized by the current induced in a serially connected pick-up coil located within a stator slot containing the quadrature main winding coil in response to the energization of the main winding coil for providing a starting torque to the rotor. Each auxiliary coil contains a first predetermined number of turns wound in a first direction within one stator slot and a second predetermined number of turns wound in a second direction located in an adjacent stator slot for increasing the resistance-to-reactance ratio. Each pick-up coil contains approximately one-half the turns of each auxiliary coil which, in turn, has a substantially lesser number of turns than each main coil.Type: GrantFiled: March 28, 1974Date of Patent: February 24, 1976Assignee: A.

Patent number: 3937887Abstract: An acoustic power system includes a speaker which generates acoustic energy in response to electrical driving signals. Electrical representations of the acoustic energy generated by the speaker are effectively subtracted from electrical input signals having a preselected frequency response to produce electrical error signals. The error signals are amplified to produce the electrical driving signals which operate the speaker. In the preferred embodiment, the electrical representations of the acoustic energy generated by the speaker are produced by detecting a portion of the impedance produced across the speaker voice coil.Type: GrantFiled: May 15, 1969Date of Patent: February 10, 1976Assignee: Ben O. KeyInventor: Francis A. Miller

Patent number: 3937686Abstract: In the preparation of high molecular weight polyamides, vaporization of the organic diamine employed results in its loss. The effect of the loss can be reduced by collecting the vapor given off during the evaporation and/or polymerization steps, condensing it, passing the condensate through a selected ion-exchange resin, and obtaining the diamine by contacting the resin with either a strong inorganic acid or an aqueous solution of an organic dicarboxylic acid used in making high molecular weight polyamides depending upon the resin employed. When the diacid is used, the salt so obtained can be used in preparing high molecular weight polyamides.Type: GrantFiled: January 10, 1974Date of Patent: February 10, 1976Assignee: C/O E. I. Du Pont de Nemours & Co.Inventor: Valdis Ansis Augstkalns

Patent number: 3930569Abstract: A power driven typewriter comprising a shiftable carrier supporting a rotatable and axially movable flexible type drum having a plurality of circumferentially extending rows of type characters thereon. Type keys, when depressed, each condition one each of two groups of actuators and cause operation of a power driven cyclically operable clutch which drives a power bail to operate the two conditioned actuators, one of which is effective to rotate the type drum from any position it may be in to a new position and the other actuator being effective to raise or lower the type drum from any position it may be in to a new position to thus align a type character corresponding to the key depressed at the printing position. Upon alignment of a selected type character, the type drum is flexed radially to cause an imprint. Means are provided to dampen torsional oscillation, wobble, etc. of the drum prior to imprinting.Type: GrantFiled: December 21, 1973Date of Patent: January 6, 1976Assignee: Thomas O'ReillyInventor: Robert E.
