Abstract: Applicant:       Carr Cedar Products, Inc.   Title:           Shim Bundle and Method of Making the Same ABSTRACT       Several courses of random width, low-grade tapered wood shingles are stacked in an elongated trough with the butts of shingles of adjacent courses disposed at opposite sides of the trough to form a substantially continuous stacked shingle lay-up.  A cutoff saw consecutively cuts loose packs of shingles from an end portion of the lay-up.  After each pack-cutting operation, the lay-up is shifted lengthwise of the trough to a position for the saw to cut another pack from the lay-up.  Each severed pack is banded about its center to form a bundle, moved lengthwise partway through a gang saw to form a set of parallel kerfs spaced apart uniformly widthwise of the bundle and extending from an end of the bundle almost up to the band and then turned end-for-end and moved length-wise partway through the gang saw to form another set of kerfs extending from the other end of the bundle almost up to the band.  The kerfs of the two sets of kerfs are in registration.  In use, the bundle band is severed and the kerfed shingles may be separated into narrow individual builder's shims by breaking the short shingle portions between oppositely extending registered kerfs.

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 OF THE DISCLOSURE An insert type attenuator arranged to function as a broad-band frequency rejection filter for pulsations in a liquid in a conduit, such as a liquid stock suspension being fed via a pipe line to a paper making headbox, which includes a housing, a conduit positioned within the housing, and a flexible diaphragm having a pair of substantially horizontal spaced runs positioned in the conduit, with means for flowing the stock suspension through the conduit, and means for intro-ducing pressurized gas into and bleeding gas from the housing and the space between the diaphragm runs.  Valve means operate intermittently in response to gross outward deflection of one or both of the runs, caused by long-term liquid pressure decreases and/or gradual increases of gas pressure build-up to vent gas from between the runs and from the housing, and thus to maintain adequate matching of the pressures of the gas cushion and of the liquid.  This maintaining of the diaphragm in a neutral, sensitively responsive condition permits it to deflect instantaneously, in both directions, as required, to "absorb" pulsations in the liquid.

Abstract: Multiple Pump System with Horsepower Limiting Control Abstract Flow-pressure compensated valves are employed in the servo-systems for variable displacement pumps to maintain pump discharge pressure above a minimum pressure level and also above the load pressure in a fluid actuator. The utilization of multiple pumps in a particular fluid circuit, each functioning to charge a separate fluid actuator, dictates the need for closely controlling the displacements of the pumps simultaneously to obtain maximum performance efficiency from the prime mover for the pumps. It is further desirable to provide a control system which minimizes the total pump envelope size.  The improved fluid circuit (10) of this invention includes a summing valve (22) for creating a control signal (Pc) in response to the collective pump pressure signals (Pp) in a plurality of fluid actuators (13) and a control arrangement (36) for controlling modulation of flow-pressure compensated valves of the above type in response to variations in the control signal (Pc).
