Title: Airfoil with integral de-icer using overlapped tubes
Inventor: RAUCKHORST RICHARD L
IPC: B64D15/18
Filed: 1993-02-05
Abstract: ABSTRACT OF THE DISCLOSURE A structural member having integral surface de-icing capability and method of manufacture are described.  The structural member includes a non-metallic high tensile modulus fiber-reinforced matrix structural backing, thin force and displacement generation means, and a thin high tensile modulus outer  skin  bonded  to  said  backing  and  said  force  and displacement generation means which is positioned between the backing and the skin.  The force and displacement generation means may include one or more inflatable tubular members preferably formed into a tube mat having bonded overlapped portions so as to distribute displacement forces.   This reduces concentrated stress and  fatigue while  increasing surface shear forces across the ice accreting surface with each tube actuation.  The structural member may be substituted for the aluminum alloy leading edge structural skin typically employed on modern aircraft.

Title: Regenerative communication channel extender
Inventor: NICOLET SCOTT J
IPC: H04L1/22
Filed: 1993-04-29
Abstract: REGENERATIVE COMMUNICATION CHANNEL EXTENDER       ABSTRACT       A regenerative digital communication channel extender is provided which converts electrical signals in a first communication network into optical signals and then reconverts the optical signals back into electrical signals for application to a second communication network.  The conversion is preferably performed using state machines.  The communication in the first and second communication networks are preferably in a first protocol, whereas the optical communication is in a second protocol.  The state machines convert the communications from the first protocol to the second protocol, and back from the second protocol into the first protocol.  In the process, the communication in the first communication network is faithfully regenerated in the second communication network.  In addition, a unique phase lock circuit is contemplated which requires only one pulse of an incoming digital communication to synchronize a local clock.

Title: A method for the direct determination of the toxicity of particulate solids
Inventor: TUNG KER-KONG
IPC: C12Q1/02
Filed: 1992-04-09
Abstract: A method for the direct determination of the toxicity of a solid material by direct contact between the solid sample and a luminescent microorganism, consisting of the steps of forming a suspension of a luminescent microorganism in a 0.5 % to 6 % solution of NaCI or 20 % solution of sucrose in distilled water diluent and contacting a sample of the solid to be tested directly with the suspension of luminescent microorganisms. A control including the microorganism in the diluent is also prepared. The combination of microorganism suspension and solid sample is incubated for a sufficient time to allow for the toxicity of the sample to affect the metabolism of the living organism. During or subsequent to the incubation period the combined organism and sample are subjected to a separation step to separate a major portion of the particulate solid from the suspension of microorganisms. The light output of the separated suspension is determined and compared with the light output of the control to arrive at the change in light output of the microorganism due to contact with the solid sample.

Inventor: KEITH PETER G
IPC: B60D1/167
Filed: 1994-08-05
Abstract: A method of connecting a trailer with a rigid drawbar and at least one centrally positioned axle to a tow vehicle is described. The method includes the following described steps.      Firstly, connect the trailer drawbar to an intermediate hitch support having rotatably mounted ground engaging wheels, such that the hitch weight is borne by the intermediate hitch support. Secondly, pivotally connect an intermediate drawbar to the trailer drawbar for movement about a transverse horizontal axis. Thirdly, connect the intermediate drawbar to a hitch support mounted on a tow vehicle, such that a towing force is transmitted through the intermediate drawbar to the trailer drawbar. Fourthly, couple the tow vehicle and the intermediate hitch support through a pair of spaced apart steering arms. The steering arms have tow vehicle ends and intermediate hitch support ends. The tow vehicle ends are spaced equidistant from an intermediate drawbar hitch point on the tow vehicle hitch support. The intermediate hitch support ends are spaced equidistant from a trailer drawbar hitch point on the intermediate hitch support. As the tow vehicle turns the steering arms cause a proportionate change in the angular positioning of the intermediate hitch support to maintain correct steering geometry. The steering arms are attached to provide for omnidirectional movement thereby accommodating relative changes in attitude between the tow vehicle, the intermediate hitch support and the trailer.

Abstract: This invention is provided to automate an adjusting job of a restaurant and to realize automatic sorting of tableware and to improve an operating efficiency of a restaurant job. Resonance tags are mounted on bottoms of plates of the tableware in which meals are dished up. The plates are placed on a tray, and the tray is placed on a tray placing position of an adjusting apparatus. A tag reader is buried in a lower portion of the tray placing position, and transmitting antennas and a reception antenna are superposed to form the tag reader. In this case, when radio waves of a plurality of frequencies are oscillated from the transmission antennas, different echo waves are oscillated from the resonance tags of the plates. When the echo waves are received by the reception antenna, the plates are sorted by the resonance frequencies of the resonance tags set to the respective plates. In this case, since a register calculates total amount according to a preset unit price of the meal, the meal on the tray is automatically adjusted.
