Abstract: ABSTRACT     A four corner joint between wall panels of the type comprising outer and inner skins connected by an insulating core, and having marginal connecting means formed along the opposite longitudinal edges of the outer skin.  The outer and inner skins and the core co-terminate at the upper ends of the lower wall panels.  The outer skins of the upper wall panels have lapping ends which extend downwardly beyond the lower ends of the upper wall panels and which overlap the wall panels.  The marginal connecting means are substan-tially entirely removed along the length of the lapping ends of the upper panels to preclude interfering with the inter-connection of corresponding marginal connecting means in the lower wall panels.

Abstract: ABSTRACT OF THE DISCLOSURE   A trailer suspension system eliminating jackknifing of the towing tractor and trailer assembly, providing stability to the trailer and more efficient braking especially during emergency stops and materially increasing vehicle maneuverability.  Steering control is provided by a connection with the towing tractor in laterally offset relation to the vertical pivot axis formed by the kingpin and fifth wheel articulate connection between the towing tractor and trailer.  The steerable wheels in the trailer suspension are sup-ported by a generally right angular spindle structure connected to walking beam assemblies for pivotal movement about generally vertical axes which are ori-ented forwardly of the horizontal axis of rotation of the steerable wheels with the spindle assemblies being interconnected by parallel, vertically spaced rods provided with universal connection with the spindle assemblies for main-taining proper orientation of the steerable wheels during their steering move-ment and during relative vertical movement.  The trailer suspension includes independently and resiliently supported axle and spindle assemblies in the form of a two axle or three axle tandem assembly with the resilient independent sup-port for the suspension axles effectively maintaining wheel contact with the ground surface for more effective braking and greater vehicle stability.

Abstract: Case 4480 ABSTRACT OF THE DISCLOSURE     The present invention relates to foundry compositions containing propylene glycol monoacetate, a silica base and a silicate,  The use of propylene glycol monoacetate as ester hardeners imparts greater compressive strength to foundry cores and the strength is built up more rapidly than with conventional ester hardeners.  This is believed to be due at least in part to the total miscibility of this ester with water and to the purity of the ester product.

Title: Solar tracking concentrator
Inventor: HORTON RICHARD H

Filed: 1979-06-13
Granted: 1982-10-05
Abstract: ABSTRACT           A solar tracking point concentrator for a solar energy system comprises a light weight reflector in the shape of a paraboloid dish having a rim angle of approximately 109°, whereby the center of gravity of the reflector mass is coincident with the focal point of the paraboloid.  The reflector is supported on a light weight pipe pedestal assembly and controllably driven by a light weight control-drive means so as to be angularly adjustable in both elevation and azimuth to track the sun and efficiently continuously reflect the sun's rays to a heat receiver disposed at the focal point of the paraboloid preferably in a fixed position.  The reflector is mounted for controlled movement to effect such angular adjustments about horizontal and vertical axes which intersect at the focal point of the reflector paraboloid.  The 109° paraboloid rim angle provides a paraboloid reflector that inherently has its center of gravity essentially coincident with its focal point.  This arrangement provides an essentially balanced mounting of the paraboloid reflector without requiring counterbalancing means.  Therefore, the paraboloid reflector may be supported by a light weight pipe pedestal assembly and driven by light weight control-drive means, such as linear stepping motors which are controlled by electronic pulses generated by light weight microprocessors.

Abstract: ABSTRACT OF THE DISCLOSURE           The invention relates to a device for the gripping of a temperature measuring device and for the reading of measuring values obtained with this device.  The said temperature measuring device comprises a temperature-sensitive sensor, whose electrical properties, e.g. the resistance, vary with the temperature, e.g. a thermistor, and which is connected via two contacts to two electric conductors arranged on a support, which electric conduc-tors terminate in two contact surfaces at the end remote from the sensor.  An arrangement in accordance with the invention, which is intended mainly to be used for medical temperature measuring, is characterized by at least two measuring contact surfaces which can be coupled together with the said contact surfaces, arranged on the inside or insides of the jaws or a tonglike construction.          These measuring contact surfaces constitute a circuit which in addition comprises a source of energy, a display unit and means for the conversion of the measuring value obtained to a value which can be read on the display unit.

Abstract: ABSTRACT OF THE DISCLOSURE This disclosure relates to a process for selectively removing and recovering potassium nitrate in a relatively pure state from tobacco, and especially from Burley tobacco stems.           The process comprises the steps of (1) contacting tobacco plant parts with water to obtain an aqueous extract and a fi-brous tobacco residue, (2) concentrating the extract, (3) cooling the extract, and (4) separating and recovering the po-tassium nitrate crystals formed therein.  The denitrated aqueous extracts is recombined with the fibrous tobacco residue as in making reconstituted tobacco and the like.  The purified potassium nitrate is suitable without further purification to use as a fertilizer, thus eliminating costly disposal problems.

Abstract: ABSTRACT           This invention relates to an apparatus and process for writing video information in the form of a frequency modulated signal upon a videodisc member and for recovering the video information from the video record.  The writing apparatus includes a laser as a source of a laser write beam and a write optical system for directing the stationary laser write beam to a moving videodisc member.  The intensity of the focused spot is changeable under the control of a light intensity modulating assembly.  This light intensity modulator changes the intensity of the write laser beam with respect to a predetermined threshold intensity sufficient to form a first type of indicia in the coating.  A read optical system directs a reading laser beam to impinge upon the successively positioned specular light reflective and non-specular light reflective regions carried by the videodisc member.  The reflected light beam is intensity modulated by the specular light reflective and non-specular light reflective regions.  The read optical system also directs the reflected light beam to a light sensing circuit for changing the intensity modulated reflected light beam to a corresponding frequency modulated electrical signal which is representative of the video signal stored on the videodisc member.
