Filed: 1961-09-27
Abstract: 956,019. Filling containers with liquid. FMC CORPORATION. Sept. 27, 1961 [Jan. 13, 1961], No. 34734/61. Heading B8T. A rotary can-filling machine in which the bottom of each can is moved outwardly to bank the can whilst maintaining the can top in alignment with a filling nozzle positioned thereabove during the filling operation, has a circular can track 20 comprising inner and outer rails 61, 66 carried on adjustable supports 38, 42 respectively mounted on brackets 33 spaced around a fixed frame 32; a curved guide rail 47 is also supported by the brackets. Cans are fed from a table 28 by a star wheel 29 to pockets 27 in an annulus 26 on a rotary turret 24, and discharge nozzles fed from a reservoir 22 are aligned with the pockets to fill the cans during their travel towards a table 31. At the filling zone A-A, Fig. 1, each nozzle is opened and a measured amount of liquid is fed into the can before it reaches the zone B-B. The inlet and outlet ends of the rails are secured to the tables 28 and 31, and the banking of the cans begins at zone C-C where they are approximately half-filled and reaches a maximum at zone 9-9 when the cans are completely filled. Banking is accomplished by gradually moving each can bottom outwardly relatively to the top by means of a can 62 on the inner rail while maintaining the outer rail 66 level with the discharge table 31; simultaneously, the can moves along a downwardly-inclined portion of the inner rail. From the zone 7-7 to zone 9-9 the angle of tilt is constant and the can is moved outwardly by the cam and the guide rail 47. After passing the zone 9-9 the can moves in a straight path and its bottom inner edge moves along an upwardly-inclined portion of the inner rail causing its upper outer edge to swing outwardly whereby the can is returned to an upright position.

Title: Improvements relating to shock acceleration measuring apparatus
Inventor: LYTH CYRIL EDWARD
IPC: G01P15/08
Filed: 1958-11-04
Abstract: 877,123. Accelerometer circuit. FERRANTI Ltd. Nov. 3, 1959 [Nov. 4, 1958], No. 35302/58. Class 40 (1). [Also in Group XL (c)] The output of a piezo-electric or electrostatic shock accelerometer is passed to an amplifier having a network arranged to provide during each pulse (square or triangular) from the transducer an exponentially-decreasing negative feedback of waveform such as to compensate for the distortion of the input waveform caused by the inherent capacitances and resistances of the transducer and its connections and the input resistance of the amplifier. In Fig. 2 the signal from a piezo-electric transducer 1 is passed through a cathode-follower 2 to the input grid 3 of a cascade amplifier. Due to the time-constants of the circuits the top of the pulse (assumed square) would droop, but this tendency is counteracted by feeding back to the upper grid through a capacitor 10 and resistor 11 a voltage which is large at the commencement of the pulse and falls off exponentially. The net anode waveform is the difference between the cathode and grid waveforms of valve 5, and can be arranged to be flat-topped. If the input is of saw-tooth form the feedback circuit prevents the top from being rounded off. The cascade circuit can be replaced by a cathode-coupled amplifier, Fig. 4 (not shown).

Title: Method of operating with gases containing carbon monoxide at elevated temperatures
IPC: C07C29/152
Filed: 1927-12-30
Abstract: 314,129. Johnson, J. Y., (I. G. Farbenindustrie Akt.-Ges.). Dec. 30, 1927. Methanol; oxygenated organic compounds.-In processes involving the presence of carbon moncxide under pressure, those parts of the wholo apparatus which are exposed to temperatures between 150‹ and 250‹ C. are constructed of or lined with a metal other than iron, whilst the remaining parts are made of iron. Since iron is corroded by carbon monoxide only within this temperature range, or even between 180‹ and 200‹ C., damage to the apparatus and also to any catalyst employed by the deposition of iron from the resulting iron carbonyl is thereby avoided. Copper, aluminium and special alloy steels are mentioned as suitable metals. The invention is particularly applicable to the synthesis of methanol and other oxygenated organic compounds. In heating up the apparatus to the reaction temperature, and also in cooling it down, contact with carbon monoxide is preferably avoided; other gases, such as hydrogen, should be present in the apparatus. According to the example, the reaction chamber for methanol synthesis operating at 400‹ C. is made of iron, whereas the heat-exchanger for preheating the reaction gases at the expense of the heat of the exhaust gases is made of manganese copper; all other parts of the apparatus are constructed of iron. Specifications 203,812, 231,285, 240,955, 247,217; 249,155, 277.273, [both in Class 32, Distilling &c.], 286,010 and 300,294 are referred to.

Abstract: 1, 071, 610. Measuring force electrically. CARL SCHENCK MASCHINENFABRIK G. m. b. H. Sept.2, 1964 [Sept. 5, 1963], No.35907/64. Heading G1N. A force P applied to deflect a disc 4, Fig. 1, relative to an annular plate 5 is transmitted via part-conical sections 2, 3 to a tubular member 1, thereby reducing its diameter, the change in its circumference being measured by a strain gauge 6. A pair of such deformable elements may be mounted back to back 7, 8, Fig. 2 (not shown) so that a force P deflecting a body (13) relative to an outer casing (10) decreases the diameter of the tubular member (6/1) and increases that of the tubular member (6/2). The strain gauges mounted thereon may be connected in opposite arms of a bridge. The pair of elements is adjusted for sensitivity by means of an adjustable spring (20) acting between the member (13) and a screw (19) in a base member (18) which is fixed to the casing (10). The pair of deformable elements may be prestressed in order to double the range of operation of the device, by means of a nut 26, Fig. 3 (not shown) which is adjustable on a threaded portion of the force receiving member 22 so that the inner discs (4) of the deformable elements may be deflected relative to the outer annular, plates (5). Hysteresis effects in the force applied/voltage output characteristic are reduced by introducing a fixed deflection between one deformable element 7, Fig. 5 (not shown) and the other (8) by means of a bolt (38). Two deformable elements may be effectively combined in one assembly of plates and cones Fig. 4 (not shown) so that one tubular element (29) decreases in diameter for an applied force P, while to second element (30) increases in diameter.
