Title: Improvements in or relating to a pneumatic gauging device
IPC: G01B13/08
Filed: 1955-06-17
Abstract: 779,747. Pneumatic gauges. SHEFFIELD CORPORATION. June 17, 1955 [June 18, 1954], No. 17538/55. Class 106 (2). A pneumatic gauging apparatus, of the kind wherein the workpiece is placed between two opposed outlet nozzles for compressed air, comprises a diaphragm 17, passages 12, 14 in communication with each side of the diaphragm and adapted for connection at 11 to the gauging system, a one-way check valve, e.g. consisting of a ball 31 in a valve seat 32, in one passage allowing free flow to the associated side of the diaphragm but preventing fluid escape therefrom and gauging means, e.g. a switch 42 operative upon a predetermined movement of the diaphragm 17. As the pressure in the system rises air passes through the valve 31 into a chamber 21 and the diaphragm 17 is kept in equilibrium. As the pressure begins to fall in the passages 12, 14, the valve 31 closes and the diaphragm 17 rises and forces upwards a pin 40 which is secured to an electrical contact arm 36 which, when in contact with an arm 4T, closes a lamp circuit. The lower arm 41 is adjusted beforehand by a screw 44 so that if the allowable tolerance is exceeded the lamp is extinguished. When the workpiece is removed the pressure falls and a projection 34 on a diaphragm 22 returning to its equilibrium position from which the pressure had displaced it, moves the ball 31 from the valve seat 32 releasing the pressure in the chamber 21, thus resetting the apparatus in readiness for the next workpiece.

Title: Improvements in or relating to the production of acetic anhydride
IPC: C07C51/56
Filed: 1947-07-03
Abstract: <PICT:0627810/IV (b)/1> Acetic anhydride is prepared by a cyclic process comprising pyrolyzing acetone to form ketene, immediately introducing the resulting gaseous mixture of ketene, unconverted acetone and fixed gases into the bottom of an absorption zone and passing it therein counter-current to a stream of glacial acetic acid to form acetic anhydride, removing acetic anhydride and unreacted acetic acid from the bottom of the absorption zone, maintaining the zone at an elevated temperature sufficient to boil off unreacted acetone, removing a vapour stream comprising acetone and fixed gases from the top of the absorption zone, condensing the vapour stream to separate the bulk of the acetone and recycling the same to the pyrolysis step and passing the fixed gases and remaining acetone to a scrubbing zone, passing them therein countercurrent to a fresh stream of glacial acetic acid, withdrawing fixed gases free of acetone from the top of the scrubbing zone and a solution of acetone in acetic acid from the bottom, and passing said solution to the absorption zone.  The pyrolysis step may be carried out at a temperature of 1150 DEG  to 1300 DEG  F. and for a time of 0.3-0.5 seconds.  The feed may be preheated when the higher temperature and shorter time are employed.  As shown, the acetone is passed via vaporizer 2 and preheater 4 to pyrolysis chamber 6 from which the products are passed to the absorption zone 8.  Here, the ketene is reacted with acetic acid introduced via line 9 and an acetic anhydride-acetic acid mixture is withdrawn at the bottom and led into fractionator 11, from which acetic anhydride is recovered at 14, the distilled-off acetic acid passing via condenser 16 to the absorption zone 8.  The unreacted acetone and fixed gases leaving zone 8 via line 12 pass through condenser 13, the bulk of the acetone being condensed therein and recycled to the pyrolysis step via line 23; the remaining acetone and fixed gases pass to a scrubber 18 maintained at between 60 DEG and 100 DEG  F., where they are washed with acetic acid introduced via line 19, the resulting acetic acid solution of acetone passing via line 9 to the absorption zone 8 and the acetone-free fixed gases leaving via vent 20.

Abstract: 632,248. Printer's composing appliances. CLOWES & SONS, W., and CROUCHER, H. G. July 9, 1947, Nos. 18119/47 and 6945/48. [Classes 100 (ii) and 100 (iii)] Furniture 1 as used to build up and locate type 6 in a chase has on one or more vertical surfaces 4b several ribs, 2, 3 projecting above the surface by a few thousandths of an inch, and which extend longitudinally of said surface, and, under a locking-up pressure of the chase, bite and embed into the type 6 or nestle into grooves 5, 4 formed in the surfaces of adjacent furniture so that the overall width of the unit of type matter formed is not increased by the ribs. The grooves 4, 5 may be semi-circular or rectangular in shape and may be a loose fit for the mating ribs but the clearance is not so great as to permit movement of the furniture to an extent that its upper surface rises to the printing surface defined by the top of the type 6b. The grooves may be on any side of the ribs or they may be spaced away therefrom. The ribs on one side of the furniture are in alignment with the grooves on the other side and in order to easily recognize each side one top edge is formed with a groove 7, a chamfer, or with wording cast in relief. The furniture, when used at a side margin between the ends of rows of type and their gripping quoins, accommodate slight inaccuracies of justification, since the ribs will bite either fully or to a lesser extent into the line end types according to whether the line is long or short respectively. In a similar way, the upper and lower ribs compensate for divergencies in the vertical parallel of the type. The ribs on the furniture adjacent to the quoins do not embed therein but form a non-slipping engagement therewith. Alternatively the quoins may be grooved to accommodate the ribs. In modified forms, the furniture may be hollow and made of either metal or alloy harder than the type metal, hard plastics, or they may be made of wood with one or more vertical surfaces faced with ribbed and grooved metal strips glued, pinned or keyed thereto. Specification 632,248 is referred to.
