Title: Stress sensor with digital output
IPC: G01L9/00
Filed: 1972-04-17
Abstract: 1390076 Stress transducer OFFICE NATIONAL D'ETUDES ET DE RECHERCHES AEROSPATIALES and LIGNES TELEGRAPHIQUES ET TELEPHONIQUES 17 April 1972 [21 April 1971] 17664/72 Heading G4H Apparatus for providing a digital output in response to an applied fluid pressure comprises a diaphragm 3, Fig. 2, in the fluid path and adapted to apply a force at 4 to the free end of a substrate 5 anchored at its other end and carrying a thin film 6 of magnetostrictive material having the property that its anisotropic axis of magnetization is rotated through an angle in response to an applied stress. It may be shown that the tangent of the angle of rotation of this axis at a point in the film is proportional to the stress at this point which as shown is conveyed to all points of the film 6 in the form of a stretching by the substrate 5 the amount of stretch varying across the film 6, and it may be shown that if an applied magnetic field is set up at a small angle # from the perpendicular to the direction of the axis of magnetization when no stress is present, on removal of the magnetic field, the axis of magnetization will return through an angle <90 degrees to its original orientation, whereas after the application of a stress, if this has caused the axis to rotate by such an extent that the axis is at an angle >90 degrees from that of the applied field, it will return to a direction antiparallel to its original orientation. The film 6 has printed thereon a plurality of parallel conductors 11, Fig. 4, at a small angle relative to the axis of magnetization under zero stress each being crossed by one arm of a similar U-shaped conductor 12 the other arm being outside the film, each crossing point of the conductors forming a sensing cell. In operation, after a stress has been applied, the clock source 24 in combination with switching control means 23 briefly close the switches 20 in leads 14 in sequence causing a magnetic flux to rise and fall across each cell in turn. The resulting electrical pulses are thereby transmitted serially to a differential amplifier 16 and via a gating circuit 17 which allows only those associated with the falling flux to pass through to a counter 18 which counts all the pulses of one or other polarity to give a measure of the stress. All those cells at which points the axes of magnetization have changed orientation as a result of the flux applied will provide a pulse of one polarity when the flux dies away and all the others of the opposite polarity.

Title: Improvements in loosening, mixing and moistening tobacco leaves
IPC: F26B3/00
Filed: 1933-06-21
Abstract: Tobacco leaves are mixed and moistened by piling them in layers upon a common conveyer band and moistening them after each laying out operation, the moistening apparatuses through which the band passes alternating with the working stations at which laying out takes place.  The tobacco is conveyed to the working stations by a lower conveyer band and the leaves are placed parallel to each other and at right angles to the direction of movement of a second upper, parallel band which conveys them through a first moistening device, adapted to moisten the tobacco from both above and below, and then through other moistening devices operating from above only.  The two conveyer bands are run at different speeds.

Abstract: 808,223. Lined tubes. METAL BOX CO. Ltd. March 25, 1957 [June 8, 1956], No. 17859/56. Class 99(2). [Also in Group XVII] The longitudinal seam of tubular carton lined with heat sealable material includes a cardboard or like strip 2 running the length of the seam and originally attached to and separated from the carton blank by a strip 14 of the lining 3 at least as wide as the strip 2, the strip 2 being enclosed by the lining in the made up carton to obviate exposure of the carton blank edge to the contents. The blank is folded so that the strip rests adjacent a portion 17 of the carton blank with two layers of the lining 3 between it and the blank, Fig. 7, to which it is then heat sealed. The blank is again folded so that the lining portion 14 encloses the edge 15 and exposed side of the strip 2 and the edge 9 of the blank is juxtaposed with the edge 16 of the strip. The portion 17 may be secured to the adjacent panel 7a. In making the cartons, a continuous web may be cut and scored to form both the carton blank and the strip, waste material 30 separating these elements being led away over rollers 31, 32. The lining is secured to the strip and blank and as shown, may be extruded onto them from a reservoir 33. The multi-ply web is folded to tubular form, the longitudinal seam formed as above described and the tube is then pleated to produce bellows folds on the creased carton sides, Fig. 9.

The coated substrates are made by adding the gellant system to a rubber latex, emulsified with one or more fatty acid or rosin acid soaps, prior to the addition of vulcanization agents, frothing the latex, spreading the foam on a textile substrate and drying and vulcanizing the foam to produce the coated substrate. The surfactant (A) may be N - coco - # - aminopropionic acid, N - lauryl myristyl - # - aminopropionic acid, sodium N - coco - # - aminopropionate, disodium N - lauryl - # - aminodipropionate or the partial sodium salt of N - lauryl - # - iminodipropionic acid.

Abstract: 516,022. Screw conveyers. AHLMANN, N. June 18, .1938, No. 18191. Addition to 457,541. [Class 78 (i)] [Also in Groups XII and XIII] In the method claimed in the parent Specification the material to be heated or cooled is moved upwards through a vertical or substantially vertical container 1 by a rotating screw 2 or its equivalent having such dimensions and such speed in relation to the coefficients of friction between the material and the screw, and the material and wall, that the material will move up the inner wall of the container in a helical path of flat pitch. In the cooler shown the material is fed by the worm 8 and is discharged through the shoot 16, while cooling is effected by water delivered through the pipe 17. In a modification, a feed hopper opens directly into the lower end of the container and a stirrer is fitted at the lower end of the screw shaft. The equivalent of a screw may be formed by flights helically arranged on a cylindrical cage of vertical bars. In a cement plant a mill may discharge into the feed hopper of the cooler, and the container may be of such height that it can discharge on to a conveyer arranged not lower than the mill.

Title: A signalling unit

Filed: 1960-05-24
Abstract: 945,889. Operating single indication receivers. F. BAUMGARTNER, [trading as FRANZ BAUMGARTNER FABRIK ELEKTRISCHER APPARATE]. May 24,1960 [June 5, 1959], No. 18242/60. Heading G4F A unit for indicating the condition of a remotely situated contact associated with a monitoring instrument includes two lamps controlled by respective transistors one of which conducts when the contact is closed and the other when it is open. The two lamps and a push-button, for testing and alarm acknowledgement purposes, are mounted in a panel fitting assembly, into the back of which is jacked a switch box assembly containing the transistors and a relay controlled by the push button. A multi-core cable 12 (Fig. 3) terminates in a plug 13 which mates with the socket (1, 2) at the remote location (Fig. 4). Normal operation-monitoring contact 25 closed. Positive potential is fed from the rectifier 49 (Fig. 4) via pin B of plug 13 to the junction of resistors 22 and 23 (Fig. 3), and negative via pin A to lead 14. With contact 25 closed the positive potential is also fed via pin C to the base of transistor 16 so that this transistor is non-conductive. Transistor 18, however, conducts and its emitter-collector current lights the white lamp 4. Contact 25 open. The positive potential is no longer extended to the base of transistor 16, which then conducts the emitter-collector current lighting the red lamp 5 via pin D and the contact of flasher 29 (Fig. 4), and energizing the hooter relay 32 via pin E. At the same time the rise in the potential of the collector of transistor 16 renders transistor 18 non-conductive, thus causing the white lamp 4 to go out. The energization of the hooter relay 32 causes operation of the hooter 52 and of the flasher 29 which flashes the red lamp 5. Depression of the push button then closes contacts 47 to bring up relay 19 which locks up and transfers the red lamp 5 to continuous negative potential via lead 14. This lamp remains lighted until the contacts 25 are again closed. The push button may also be used to test operation of the unit, opening of contacts 27 while contacts 25 are closed removing the positive potential from the base of transistor 16, thus simulating opening of contacts 25.
