Title: Ceramic heater roller with thermal regulating layer
Inventor: HYLLBERG BRUCE E
IPC: G03G15/02
Filed: 1994-01-31
Abstract: A thermal conduction roller (10) for use in industrial and office equipment includes a ceramic heater layer (13) and a second ceramic layer (12) disposed in between the ceramic heater layer and the core. The second ceramic layer (12) has a resistance characteristic such that resistance of the roller decreases with heating to approximately the same order of magnitude as resistance in the longitudinal direction. This causes electrical current to be diverted from the ceramic heater layer (13) to limit the temperature in that layer and any outer layer (17) contacting a work object.

Title: System for controlling and operating a cow-milking carousel
Inventor: OSTHUES UWE
IPC: A01K1/12
Filed: 1994-07-22
Abstract: In order to control the speed of rotation of a carousel milking installation (1), one selects first the maximum carousel speed. The animals enter the carousel by the entrance (2) and the milking equipment is immediately put in place by the attendant. When the first animal arrives at the second checkpoint (6), a check is made, by means of a light barrier for instance, as to whether the milking equipment has been taken off or not. If it has not yet been taken off, the speed of the carousel is decreased in steps until, at subsequent milking stations (4), the milking equipment has been taken off before the checkpoint (6). When, however, the first checkpoint (5) reports that the milking equipment has already been taken off by then, the speed of the carousel is increased in steps until animals with milking equipment which has not yet been taken off are again reported at the second checkpoint (6). The speed is then reduced again in steps. The control procedure repeatedly alternates and enables the speed of the carousel to be adapted to differences in milking time between different animals.

Abstract: A stereo slide mount is divided into a base frame  (21)  and  a  cover  frame  (22)  in  order  to facilitate  the  operation  for  mounting  the  stereo slide and to improve correctness.  The size of the windows of the base frame is equal to the size of the pictures of the films, and pins (25) are provided at four  corners   of  the  windows   to   engage  with perforations of the film.  The cover frame  (22)  has holes  (26)  that correspond to the pins (25)  and can be fitted to the base frame. The cover frames  (22) are prepared in plural kinds  (#0,  #1, ---)  in which the width  (C1)  between the windows is equal to the width between the windows in the base frame, and the width (W) of the window decreases stepwisely. Plural kinds of masking-amount guide devices (31) having the same size of windows as that of the cover frames and having a collimation pattern at the same position on the  right  and  left  windows,  are  successively  and temporarily fitted to the base frame  (21),  and the image of the stereo slide films is observed using a stereo slide viewer.  The  films are mounted on the base frame by using a cover frame of the same number as the number (#) of the masking-amount guide device (31) with which the sense of distance to the subject in a close-range view is in agreement with the sense of distance to the collimation pattern (35). There is thus obtained a stereo image with the parallax being suitably corrected.

Title: Sensor including two entwined spiral electrodes
Inventor: HONKANEN MATTHEW J
IPC: G01R31/02
Filed: 1996-06-18
Abstract: An electrical sensor for resistance and capacitance measurements which includes two entwined spiral electrode tracks and an electrical circuit for testing the integrity and electrical continuity of the electrode tracks are disclosed. The entwined spiral electrode tracks maximize the effective surface area of the sensor while generating a uniform electric field across the surface of the sensor. The terminal leads at the ends of each electrode track are connected to an I/O pin of the microprocessor. In testing the sensor, the microprocessor applies a reference voltage signal through one of the electrode tracks through one of the I/O pins. If the microprocessor fails to read the reference voltage signal at the oppositely connected I/O pins on that electrode track, the microprocessor indicates a continuity failure in that track. If the microprocessor reads a voltage signal at one of the I/O pins connected to the other electrode track, the microprocessor indicates a short failure between the electrode tracks.

Filed: 1996-09-25
Abstract: A pressure swing adsorption air prepurifier is used to remove water, carbon dioxide and hydrocarbons from a feed gas stream, such as a feed air stream, passing to a cryogenic air separation plant. By the incorporation of a regenerative heat exchange as an integral part of the air prepurifier, the cooling effects of the desorption of water are stored and transferred so as to cool the incoming feed air stream passing to the adsorbent material within the air prepurifier. The productive capacity of the adsorbent material is enhanced thereby.
