Title: Trap apparatus with bypass
Inventor: GILLINGHAM GARY R
IPC: F01N13/04
Filed: 1991-09-10
Abstract: Trap muffler apparatus (242) with bypass to a common reactive acoustic element (250, 270) is disclosed. Bypass structure varies from external bypass to a common acoustic element (250, 270) to annular bypass of the ceramic filter to axial bypass through the middle of an annular ceramic filter (256, 254).

Title: A device for measurement of electrical impedance of organic and biological materials
Inventor: OLLMAR STIG
IPC: A61B5/053
Filed: 1991-10-18
Abstract: A device far depth-selective, non-invasive, local measurement of electrical impedance of organic and biological materials such as tis-sues from vegetable or animal origin comprising a probe (Fig. l-3; 9a, 9b) with a number of electrodes (A, B, C) driven from an electronic control unit (F) in such a way that the electric current path defining the actual tissue under test is dependent upon a control signal. The probe is pressed toward the surface of the body part under test and by varying the control signal, it is possible to select the region under test within limits determined by the shapes, sizes and distances of the elec-erodes and the properties of the tissue under test. By means of combin-ing results obtained with different control signals, it is possible to compute local impedance profiles.

Title: Single article newspaper dispensing apparatus
Inventor: ELDER RICHARD A
IPC: G07F11/04
Filed: 1993-04-26
Abstract: SINGLE ARTICLE NEWSPAPER DISPENSING APPARATUS   ABSTRACT        A single article dispensing apparatus adapted for newspaper vending captures a bundle of newspapers between opposing support plates with one movable plate being spring biased toward the stationary plate.  Newspaper engaging pins extend beyond the stationary support plate and into the space between the opposing support plates to engage the back edge of a newspaper of the bundle.  Upon deposit of the necessary coins and pulling of a dispensing handle, the newspaper engaging pins slide the newspaper from the bundle and out through an output door of the vending machine.  When all newspapers in the bundle are dispensed and the support plates come to direct face-to-face opposition, a last copy of the newspaper held behind a display window is automatically dispensed upon the next actuation of the dispensing handle.  The vending machine restricts access to the inventory of newspapers and allows a purchaser but one copy of the newspaper for payment of one copy.

Filed: 1993-05-12
Abstract: The object of the invention is to make it possible to detect vibrations which would destroy a micro-gravity environment, to grasp factors of the vibrations, to detect and grasp a position and a scale of meteoroid/debris collisions, and to establish a counter-measure.         Vibration sensors are disposed in a matrix array on a vibrating body placed in a micro-gravity environment, and the vibration data are collected and fed to a computer.          The computer analyzes a spectrum of the vibration, in a neural network section a vibration source is specified on the basis of the analyzed spectra, in a fuzzy control section, actuators are driven so as to reduce harmful vibrations in response to the vibration energy and the energy source specified by the neural network section, and if necessary, a vibration factor is eliminated.  The computer takes in the result of driving for the actuators, the results are learnt in the neural network section and in the fuzzy control section to be ready for generation of vibrations at the next time.  The vibration sensor comprises a reflector or a transparent refractor disposed as floating in a micro-gravity space, output means fixed to the vibrating body for emitting energy towards the reflector or transparent refractor, and a receiver fixed to the vibrating body for receiving energy sent from the reflector or transparent refractor and measuring the nature of vibrations of the vibrating body on the basis of movement of the reflected or permeated energy.

Abstract: A series of remote input/output repeater modules (12a-12d) connected on a synchronous serial communication network supervised by a programmable logic controller(10) uses a synchronous serial communications protocol. The programmable logic controller (10) contains a transmitter module (16) for generating a data packet containing the state of output devices (24a-24d) connected to the remote input/output repeater modules (12a-12d).  A receiver module (18) receives and decodes a returned modified data packet that indicates the state of input devices (22a-22d) connected to the same or other remote input/output repeater modules (12a-12d). The remote input/output repeater modules,(12a-12d) receive and decode the data packet to determine the state of the output devices (24a-24d) that may be connected to it and modifies the data packet to indicate the state of its input device (22a-22d) if there is one present. The modified data packet is sent to the next in-line remote input/output repeater module (12a-12d) coupled to the network.
