Abstract: ABSTRACT OF THE DISCLOSURE         Disclosed is a self-supporting trailer having at least a pair of rear wheels and a steerable and casterable front wheel with the weight of the trailer being substantially equally divided among the wheels. The front wheel is carried for turning movement by a yoke which is secured to the trailer frame by leaf springs. The leaf springs provide rigid and lateral stability between the yoke and frame and enable vertical movernent of the frame relative to the yoke. The steerable wheel is carried by a fork pivotally coupled to the yoke. A drawbar is bifurcated at its rearward end for connection to the yoke arms and pivotal movement about a horizontal axis. The opposite end of the draw-bar carries a tongue mounting a hitch for connection to the towing vehicle and a steering arm carried by the fork whereby the steering wheel tracks the turning movement of the towing vehicle. The hitch connection with the towing vehicle and the horizontal pivotal axis of the drawbar and yoke define a plane and the pivotal connections at opposite ends af the steering link are maintained in this plane throughout the range af angularity of the drawbar resulting from any difference in elevation between the towing vehicle and the trailer.          With the foregoing construction, vertical loading of the towing vehicle from the trailer is substantially minimized or eliminated and lateral stability is assured by the steering and casterable front wheel of the trailer.

Granted: 1984-06-19
Abstract: ABSTRACT An optical device such as an optical isolator or an optical modulator according to the invention comprises a 45° Faraday rotator or an electrooptic crystal which is interposed between tapered plates of birefringent material for separating and combining polarized light.  The optical device is polarization independent, and it can be miniaturized with fewer components than prior art optical devices.  The optical isolator also allows one hundred percent of light in the forward direction to pass through it. The optical modulator can be used as a voltage sensor.  The tapered plates are made of rutile or calcite.

Abstract: ABSTRACT OF THE DISCLOSURE        An oscillator is proposed which comprises a pair of cylinders having a common, circular-cylindrical outer wall (100) and two sealingly guided pistons (120, 122) each having one piston rod (121, 123), which are likewise guided in a sealing manner to the outside through the closure walls of the cylinder.  The cylinder is divided by the pistons (120, 122) into outer chambers (124, 125) and inner chambers combined into one common chamber (126) The chamber (126) is filled with fluid.  The outer chambers (l24, 125) have two openings (102, 103) offset from one another by 180°.  A control cylinder (101) having axially offset, oppositely disposed holes (104, 105, 106, 107) connects the outer chambers in alternation with an annular high-pressure chamber (113, 115) and an equalization chamber (114) whenever the control cylinder (101) is rotated.  The two pistons (120, 122) thereby execute movements in common toward the left or right, respectively.          The stroke is determined by the quantity of fluid capable of flowing out of the high-pressure chamber and into the equalization chamber, and the frequency is determined by the speed of rotation of the control cylinder.  A direct control of an oscillator is thus realized, without addi-tional connecting lines and the delay associated with such lines.  Frequencies of up to 7000 Hz and strokes up to 10 mm can be generated.     (Fig. 4)

The secondary and higher order spectra (i. e. second and higher harmonics) of a broadcasted AM stereophonic signal are minimized by limiting the amplitude of the audio signal, prior to modulation onto the carrier, within a predetermined portion of the audio frequency range.  This is achieved by controlling the gain of the audio signals in that predetermined portion as a function of the level of a submodulation component also within that predetermined portion of the audio frequency range.     -i-

Abstract: ABSTRACT OF THE DISCLOSURE      The formation of a body of material on a substrate having at least two layers of different composition is made possible by the improved system and method of the present invention with minimized cross contamination between the respective deposition environments in which the layers are deposited.  The disclosure relates more specifically to the use of the system and method for the deposition of multi-layered amorphous silicon alloys to form photovoltaic devices.          As a preferred embodiment of the invention, first, second, and third glow discharge deposition chambers are provided for depositing respective first, second, and third amorphous silicon alloy layers on a substrate.  The second layer is substantially intrinsic in conductivity and differs in com-position from the first and third layers which are of oppo-site conductivity type by the absence of at least one ele-ment.  The second chamber is provided with starting mate-rials including at least one gas from which the deposited layers are derived and the first and third chambers are provided with respective dopants to render the first and third layers opposite in conductivity.  Contamination of the second chamber by the dopants in the first and third cham-bers is prevented by the establishment of unidirectional flow of the at least one gas from the second chamber to the first and third chambers.

Abstract: ABSTRACT           An operating or control part, essential to the starting-up or use of a power-operated device (1), e.g, driven by an engine or a pressure-medium, is made in the form of a tool-carrier(4).  Permanently attached to the tool-carrier is at least one tool, preferably a set of tools, specifically intended for the maintenance, cleaning, or the like of the device.          However, the operating part constituting the tool-carrier is arranged detachably upon a functional  element (2,3) of the said device.  It is therefore scarcely possible for the tool to be lost after it has been used, since the device only becomes serviceable again (i.e. may be driven or guided by the operator) after the operating part which has been removed, and which constitutes the tool-carrier, has been replaced.

The limiting member (10) causes a constriction in the external portion (4') of the flow chamber, and such construction decreases from the housing tongue towards the pressure pipe outlet.

Wendschlag Abstract A heat pump system and method, wherein the system may be operated in cascade fashion to heat water using heat extracted from relatively cold outdoor ambient air, or in non-cascade fashion to provide supplemental heating or cooling in a comfort zone.

In a first mode of operation, the first refrigerant fluid condensed while heating water is vaporized in the tri-fluid heat exchanger to cool air supplied to the comfort zone, and in a second mode the first refrigerant fluid is vaporized by heat rejected from con-densing the second refrigerant fluid.  In a third mode, wherein only the second refrigerant loop is operative, air passing through the tri-fluid heat exchanger to the com-fort zone is heated by condensation of the compressed second refrigerant fluid.
