Abstract: SELF ADJUSTING ENERGY ABSORBER            ABSTRACT OF THE DISCLOSURE     A shock absorber including a housing having a ram slid-ably extending therefrom.  A pair of concentric control sleeves divide the housing into inner and outer fluid cham-bers, and a piston is slidably received within the inner chamber.  The inner sleeve has an axially aligned row of openings therein, and also has an elongated groove formed in the outer periphery thereof, which groove is circumfer-entailly spaced from the row of openings.  The inner and outer sleeves have opposed conical surfaces forming a nar-row clearance space therebetween.  A spring coacts between the housing and the outer sleeve for urging same axially in a direction whereby the openings in the inner sleeve are effectively closed, as by maintaining the narrow space at a minimum dimension.  When a shock load is imposed on the ram causing the piston to move inwardly within the in-ner chamber, the fluid therein is pressurized and flows through the openings into the narrow space.  The pressure of the fluid reacts against the conical surface on the outer sleeve and causes it to be axially displaced in opp-sition to the urging of the spring, thereby increasing the dimension of the narrow space whereby the fluid flows there-through into-the adjacent groove, from which it is dis-charged into the outer chamber.

Abstract: ABSTRACT OF THE DISCLOSURE           A depth control device is attached to agricultural implements such as cultivators, seed drills, discers and the like, in order to control, within pre-determined limits, the depth of penetration of the earth working components.  It com-prises firstly a ground or surface engaging sensing member ex-tending forwardly of the framework and secondly, a sensor that is connected to the earth working components.  Both of these sensors are connected to the means to raise and lower the earth working components which controls the depth of penetra-tion thereof so that, for example, if uneven ground is encoun-tered, the depth penetration is corrected and if the density changes of the ground being worked, thus affecting the suction, then once again depth penetration is corrected.  Means are provided to average out the effect of conditions changing the depth of penetration so that the desired average depth of pene-tration is maintained particularly in relatively wide machines.   Switches are actuated by the sensors and these switches are connected to solenoids or solenoid valves which in turn operate the raising and lowering mechanism for the earth working com-ponents, said mechanism being operated either by hydraulic rams or reversible electric or hydrostatic motors.

Abstract: In re application of Jack M. Brandstadter For:  Hydropneumatic Suspension System ABSTRACT OF THE DISCLOSURE         A hydropneumatic suspension system consists of plural separate individual wheel suspension units, one for each wheel, whereby should damage occur to any one of the units, it will not affect the operation of the other units.  The heat generated by each individual wheel suspension unit is kept to a minimum, and the heat that is generated is dissipated through the vehicle hull by locating the valving and fluid passageways in close proximity to the hull.  Increased heat dissipation may also be obtained by providing an air cooled tube in the fluid path between the actu-ator and accumulator, and by providing a flow path for the return fluid from the accumulator to the actuator in the unit mounting flange which is bolted or otherwise secured in close mating engagement with a large surface area of the vehicle hull.

Abstract: VARIABLE CHARACTER SPACING MATRIX         FOR PROPORTIONAL SPACING PRINTING SYSTEMS          Abstract:    The aesthetic characteristics of adjacent characters are used to enhance the quality of output in a pro-portional spacing printer and to provide right margin justi-fication for composing.  Spacing between characters is determined not only on the basis of the character being printed, but also on the preceding character already printed on the page.  An intercharacter displacement memory is provided which contains a list of ideal spacing for all combinations of characters to be printed.  As each character is typed, it and the previously stored preceding character address the intercharacter displacement memory.  The output of the intercharacter displacement memory is the ideal value of escapement for this particular combination of characters and font style.  The printer automatically repositions the print head prior to printing the next character, rather than positioning the print head after the previous character is printed.  Line ending decisions for composing are eliminated during initial and final typing of a document by adding to the intercharacter displacement memory recommendations for altering the ideal spacing between characters, where aesthetically possible, to eliminate the need for line ending hyphenation.  During initial keying of each line, escapements for each adjacent pair of characters is totaled in a memory for ideal, shortest (tight), and longest (loose) 1.   recommended escapements.  The line is automatically termi-2.   nated within the justification range by a carrier return 3.   function based on the escapement totals and the selected 4.   right margin.  Final playout of the page from memory alters 5.   the intercharacter escapements from the ideal values to 6.   either longer or shorter escapements depending on whether 7.   the line is to be lengthened or shortened.
