Abstract: ELASTOMERIC SUSPENSION SYSTEM FOR WHEELED VEHICLES          ABSTRACT OF THE DISCLOSURE      An elastomeric suspension system for wheeled vehicles includes an equalizing beam pivotably mounted about its center to a trunnion tube which is rigidly mounted to the frame of the vehicle.  The trunnion tube is press fitted into an aperture in a trunnion rubber bushing which, in turn, is press fitted into an aperture in the equalizing beam.  Near each end of the equalizing beam is an axle mounted transversely to the beam.  Each axle has mounted thereon one end of a cylindrical elastomeric spring which is connected at its other end to the equalizing beam.  A rebound shaft is slidably connected at one end to each axle and at the other end  to each end of -the equalizing beam to prevent excessive rebound of the equalizing beam with respect to the axles.  Each axle is pivotably connected to a central portion of the equalizing beam through radius rods.  The elastomeric rubber spring isolates a substantial amount of vibrations of the axle, particularly vertical vib-ration, from the equalizing beam.  Each radius rod acts as a guide for the vertical movement of a respective axle. The trunnion rubber bushing further isolates any vibration of the equalizing beam from the trunnion tube.

Granted: 1980-12-02
Abstract: ABSTRACT         A method and apparatus for decoding transmitted binary data in which net DC components have been suppressed.  The data is transmitted in successive clocked bit cells of a transmission channel wherein logical first bit states, e.g., 0's, are normally transmitted as signal transitions relatively early in respective bit cells, preferably at cell edge, and logical second bit states, e.g., 1's are normally transmitted as signal transitions relatively late in respective bit cells, preferably at mid-cell, and any transition relatively early in a bit cell following a transition relatively late in the next preceding bit cell is suppressed.  The onset of a sequence of second bit states following a first bit state that might introduce a DC component into the transmitted signal with normal transmission is detected by producing a first indicating signal, and in response to the first indicating signal, the state of a current bit and the state of the next succeeding bit, the transmission of signal transitions is modified to eliminate any DC component.  The decoding apparatus includes a synchronizer responsive to transmitted signal transitions for providing timing signals for distinguishing relatively early transitions from relatively late transitions and a detector responsive to transmitted signal transitions and the timing signals for indicating first bit states upon receipt of relatively early transitions and second bit states upon receipt of relatively late transitions.  A            Abstract...continued.   suppressed transition detector is responsive to transmitted signal transitions and the timing signals for detecting the absence of a transition for an interval corresponding to 2 1/2 bit cells following a relatively late transition by producing a suppressed transition detection signal.

Abstract: Fluid Sequence Bypass Apparatus Abstract In some piston engines a pressurized fluid which is delivered to a main receptor is also delivered to a secondary receptor from which it is directed  to cool the pistons.  During engine startup and low idle operation such cooling is unnecessary, and further, it is desirable to provide as much fluid flow as possible to the main receptor, which is generally the main lubricating manifold of the engine.  Herein, delivery of the pressurized fluid to the secondary receptor is prevented until the fluid pressure in the main receptor reaches an initiating value.  The main receptor thus receives added fluid flow at startup and during low idle operation, while adequate piston cooling is provided at normal operating speeds.

Abstract: Pumpless Flow System for a Corrosive Liquid Abstract A system for transporting a highly corrosive liquid solely by pressure differential without the need of mechanical pumps for transporting the corrosive liquid.  The system includes a source of gas under pressure and first and second corrosive liquid reser-voirs connected in parallel to the source via a valve such that one or the other, but not both, may receive pressured gas.  A valve connects one or the other, but not both, of the reservoirs to a point of use of the corrosive liquid and is specifically designed for con-necting the reservoir receiving the pressurized gas to the point of use.  A valve receives corrosive liquid from the point of use and directs the same to one or the other, but not both, of the reservoirs, and is specifically designed to provide the corrosive liquid to the reservoir not then receiving pressurized gas from the source.  Air displaced from the reservoir receiving the corrosive liquid is directed to a scrub-ber and then returned to the pressurized gas source for subsequent reuse.

Abstract: PNEUMATIC SWITCH CONTROL FOR PNEUMATIC ACTUATOR IN AIR CONDITIONING CONTROL SYSTEMS          Abstract Of The Disclosure Heating, ventilating and air conditioning control systems commonly use pneumatic actuators.  A digital logic control has first and second output ports applied to control the actuator through dual channels, including an air supply channel and an air exhaust channel.  Various sensed and related input signals are processed by the logic device and generate control sig-nals at the control signal ports.  Each channel includes an electrically controlled switch unit having an elec-trical operator and a pneumatic switch for controlling the flow to and from the pneumatic actuator.  The switch may take the form of an electromagnetically actuated flow valve opening and closing a flow path from a supply or exhaust to the pneumatic actuator or, in the case of the supply channel, the form of a small electrically operated pump unit.  The actuation of the actuator is controlled either on a time or frequency basis to set the actuator in the proper position.  Pneumatic resis-tors in the output lines to the actuator provide fluid rate control to and from the actuator.

Abstract: TITLE            ANCHORING SYSTEM FOR FLOATING MOORAGE     ABSTRACT OF THE DISCLOSURE         A system for anchoring a large number of intercon-nected mooring floats in either deep or shallow bodies of wa-ter.  The system includes a grid of post-tensioned cables pos-itioned beneath the floats and a number of anchoring lines ex-tending between the grid and attachment fixtures forming part of the floats.  The anchoring lines are symmetrically secured to the floats so that a force exerted by a line in one direc-tion is opposed by an equal force exerted by another line in the opposite direction.  Further, the angles of the anchoring lines with respect to the horizontal are maintained relatively small to minimize the downward force on the float exerted by the tension in the lines.  A plurality of spaced apart weights are secured to the anchoring lines to maintain the tension of the lines as the floats rise and fall responsive to tidal changes.  The attachment fixtures are formed by tubes extend-ing vertically through the floats adjacent their edges receiv-ing a chain connected to an anchoring line.  The chain is locked into position by inserting the chain into a notch form-ed at the upper end of the tube.

Abstract: ABSTRACT OF THE DISCLOSURE         The invention relates to a method of high-frequency welding of sections of a flange-web type.  In accordance with the method flange blanks and web blanks to be welded are taken.  At one side the ends of the blanks are brought together by bending the flange blank round a variable-sign radius until it touches the web blank at the point of convergence.  A high-frequency current is applied through contacts to other drawn-apart ends of the blanks.  Then both the blanks are heated and pressed together.  The intensity of heating of the blanks is changed by inducing an electromotive force in the flange blank and by inducing an additional electromotive force in the web blank on the side of the lateral surface thereof. The apparatus for carrying out the method consists of a high-frequency current source, current-carrying conductors electrically associated with the current source, and con-tact tips of the current-carrying conductors for trans-mitting the high-frequency current to drawn-apart ends of the blanks.  Squeeze rolls, whose axes of rotation lie in the planes perpendicular to the web blank, act on the drawn-apart ends of the blanks.  A device for inducing an electromotive force in the flange blank is made in the form of a current-carrying busbar arranged oppositely to the web blank and equidistantly to the external surface of the squeeze roll acting upon the flange blank.  A tension-ing roll is installed with a gap relative to the squeeze roll acting on the flange blank, sufficient for passing the flange blank between these said rolls.  A device for in-ducing an additional electromotive force in the web blank is disposed between the squeeze rolls and the contact tip and the conductor supplying current to the web blank.
