Abstract: ABSTRACT OF THE DISCLOSURE         A truck upright having a fixed upright section, one or more telescopic upright sections, and a load carrier mounted on an inner upright section.  An asymmetric lift cylinder assembly is located adjacent one side of the upright in a position which pro-vides improved overall operator visibility through the upright.          The lift cylinder is adapted to be operatively connected at its upper end to a telescopic upright section for operating lifting chain structure which traverses laterally across the upright and which is reeved on spaced and rotationally aligned sprockets sup-ported either from a telescopic upright section or from the lift cylinder assembly, the one chain end structure being connected in the two stage upright hereof substantially centrally of the lift-ing or fork carriage, and the other chain end structure being fixedly secured outwardly of one side of the cylinder assembly to a member, such as to the adjacent outer upright rail.  The cylin-der assembly is operatively connected to the telescopic upright section at or near a location which is one-half the projected distance between the chain end connections, or in a broader sense, approximately midway between the vertical central plane of the load carrier and the chain end connection outwardly of the cylinder assembly.  In the triple stage upright as disclosed the one chain end structure is connected substantially centrally of the inner telescopic upright section (load carrier) on which is mounted the lifting or fork carriage, and a cantilevered cylinder is mounted in the inner upright section for elevating thereon the lifting carriage to a full free-lift position.  A fluid pressure supply hose is connected between the base ends of the primary and  secondary cylinder assemblies, and is reeved in an inverted U-shaped loop between opposite sides of the upright.  Otherwise Abstract continued: the same principals of construction apply as expressed above.          In any multi-section upright using this invention, whether two of three or more sections and regardless of other variations in upright design, the asymmetric cylinder assembly is located such that it projects at least partially into the area of interference by the adjacent side of the upright when in a retracted or collapsed position with the visibility of the operator from his normal line of sight through that side of the upright.

Abstract: MODULAR INFLATABLE DOME STRUCTURE               BY Y. T. Huang Y. T. Huang & Associates, Inc. P.O. Box 31596, Dallas, Texas  75231 ABSTRACT           A modular dome structure constructed by using uniform Y joints which have branches forming angles of 1205), 120° and 108°. The Y joints are interconnected by uniform length members to form pentagonal and hexagonal structures. These modular structures are interconnected to form a modular dome structure which may have a pentagonal apex structure or a hexagonal apex structure.           All members are made to harden after inflation due to vulcanization and curing process, so that permanent resistance to stress and strain will be provided in its final form. Due to inflatability of members, the logistic involved in actual construction will be kept minimum, and the freight cost for material transportation will be saved significantly.

Abstract: ABSTRACT OF THE DISCLOSURE         A method and apparatus for monitoring the degradation of oil, particularly crankcase oil.  A first sensor includes creep material position-ed under constant stress in thermal contact with the oil to act as an analogue computer as it changes its length in response to temperature and the time at that temperature to register the degradation of oil due to the oil's oxida-tion.  In addition, a second sensor registers the contamination of the oil by adding the number of times the oil is heated but not heated to a high enough predetermined temperature to disperse the water, acids and sludge which contaminate the oil.  When the combination of these outputs reach a predeter-mined limit, a signal is provided.  This is accomplished by an apparatus including a generally U-shaped bracket with a platform movably supported on the bracket for upward movement against a spring.  A rod extends through the platform and is connected to a diaphragm which, in turn, is subjected to oil pressure to move downwardly thereby moving the rod downwardly.  A creep material is supported on the platform and extends upwardly in the direction of the rod to a distal end and is placed under a constant stress by a spring reacting between the distal end and the platform.  The creep material changes in length exponentially when subjected to temperature and time, the operand of the exponent being the base of the natural system of logarithms.  Associat-ed with the platform is a metal member having a pair of gripping tangs engaging the rod so that when the rod moves downwardly and returns after the oil pressure is released it will move the platform upwardly relative to the bracket unless the oil reaches a predetermined temperature at which time the tangs will move away from the rod allowing the rod to freely return upwardly without moving the platform.  When the combination of movement or elongation of the creep material and platform movement upwardly is sufficient that the distal end of the creep material contacts the upper portion of the bracket an electrical signal is provided indicating that the oil is sufficiently degraded to be replaced.

Abstract: ABSTRACT The baseplate of a shear wave seismic vibrator is vibrated to generate a shear wave of predetermined waveform.  The resulting seismic waves are recorded.  The pressure waves also generated by the shear wave vibrator appear on the record as noise.  The baseplate is then vibrated to generate a shear wave of predetermined waveform which is substantially the same as but substantially opposed in phase to the previous shear wave generated.  The resulting seismic waves are then detected and subtracted from the previous record to reduce noise caused by pressure waves simulta-neously generated by the shear wave vibrator.
