Title: Improvements in the manufacture of ketene, acetic anhydride or a homologue thereof
IPC: C07C45/89
Filed: 1936-07-17
Abstract: In the production of acetic anhydride, ketene and their homologues by thermal treatment of aliphatic acid vapour, the reaction is effected in the presence of a completely amidated acid of phosphorus.  The amide groups may contain aliphatic, aromatic, or hydroaromatic radicles, a large number of such bodies being mentioned.  The amidated acid of phosphorus may be used together with ammonia or an organic base as referred to in Specification 317,907, [Class 2 (iii)].  The amide may be dissolved in the main bulk of acid to be treated or may be injected into the heated acid vapour, preferably in the form of a solution in a solvent which may be a portion of the acid to be treated or may be a liquid which will facilitate the final separation of the anhydride, for instance, by forming an azeotropic mixture with water.  The invention is described with reference to the treatment of acetic acid, but other acids such as propionic and butyric acids may be used.  Specifications 280,972, [Class 2 (iii)], and 478,325 also are referred to.

Abstract: 1511832 Plasma arc furnace TETRONICS RESEARCH & DEVELOPMENT CO Ltd 30 April 1975 [7 May 1974] 20160/74 Heading H5H The disclosure is similar to that of Specifications 1,390,351, 1,390,352 and 1,390,353, but the orbiting electrode 3 is mounted with its longitudinal axis offset from the orbital axis 8 and with its arcing tip directed inwardly towards the stationary electrode 2 so that when electrode 3 is orbited rapidly enough a radially expanded plasma arc column 6 which has a frusto-conical portion whose base is adjacent the orbital path of the electrode 3 is formed. This enables particulate material to be introduced into the plasma column through a central bowl shaped plasma free region 7 formed at the upper end of the plasma column 6 without impinging on the electrode 3. This is in contrast with the method of introducing particulate material as cylindrical curtain about the orbiting electrode to the plasma column as disclosed in the above mentioned Specifications. The orbiting electrode 3 can be consumable, non-consumable or a plasma gun. Three axially adjustable orbital electrodes may be provided. Secondary feedstock may be introduced to the plasma column 6, which is of the form of two cones whose apices engage, at the point of maximum energy, by way of three ducts 9.

Title: Turn controller for automatic pilot systems
IPC: G05D1/04
Filed: 1948-08-03
Abstract: 668,169. Automatic control systems for aircraft. BENDIX AVIATION CORPORATION. Aug. 3, 1948 [Sept. 18, 1947], No. 20462/48. Class 38 (iv). In an automatic pilot, banked turns are effected manually by means of a control knob which causes the simultaneous generation of separate voltages in the aileron, rudder and elevator control channels. As shown, Fig. 2, the arrangement is applied to the system described in Specification 662,831 and the turn control knob 55 disconnects the auto-pilot direction control device and positions the rotor coil of the rotary transformer 51, the output from the stator of which produces three independent voltages at the secondary windings 61, 62, 63 of transformer 60 which are each applied separately to the rudder, aileron and elevator control channels. The rudder and aileron signals at 61, 62 have an amplitude and phase dependent upon the extent and direction of rotation of 55 and are respectively amplified by the valves 67, 80. The elevator control signal developed at 63 is applied to the phase discriminator 92, 93 the output from which passes through either the transformer 103 or 108 depending upon whether a left or right hand turn is being executed. The outputs of 103, 108 are adjusted by means of potentiometers 111 and 113 to give signals of unequal amplitude in order to counteract the gyroscopic effect of the propeller.

Title: Shank lasting mechanism of lasting machine
IPC: A43D21/12
Filed: 1962-05-29
Abstract: 963,513. Shank lasting. E. G. HENKEL, [trading as E. G. HENKEL [firm of] ] May 29, 1962 [Jan. 4, 1962; Jan. 9, 1962], No. 20688/62. Heading A3B. A shank lasting mechanism 1 has a plurality of individual wiper fingers 16 (Fig. 1) each of which is independently and resiliently movable as a whole in a direction at right angles to its length, between a basic position and an operative position in which the tips of the fingers abut the bottom of the last. The lasting mechanism 1 is slidably mounted on a plate 5 which is secured by arms 3 to the rest of the machine. In one embodiment the wiping fingers 16 which have bevelled ends 7, and are each pivotally connected to two levers 21, are of an equal length. The levers 21 pivotally connected to shafts 22 form a parallelogram so that the wipers are always horizontal. The shafts 22, and thus the finger tip line 23 (Fig. 2 not shown), have a curvature corresponding to the shape of the horizontal projection of the shank area of a medium sized last. So that the shafts can move in an axial direction to adjust the curvature of the tip line, the ends of the shafts are mounted on slide members 25, one of which is connected to a screw 33 (Fig. 2). Each lower lever 21, and thus each finger, is pressed upwards by a spring 38. To adjust the fingers vertically to the shape of the last, they are first pressed down to the basic position by a handle 48 and locking lever 51, and secondly after the last is inserted, the locking lever is released allowing the fingers to rise till they engage the shank of the last. By turning an eccentric shaft 46 the levers are clamped against the side of the casing. During lasting the arms 3 move the mechanism 1 towards the last so that the bevelled edges 17 wipe the upper on to the insole. Alternatively the shafts 22 may be straight and the fingers 16 of varying length (Figs. 5 and 6 not shown). Auxiliary fingers 58 (Fig. 7) may be provided between the toe or heel wipers and the shank fingers to extend the range of the mechanism 1 for larger shoes. The fingers 58 are urged to their operative position by springs, unless in the case of smaller shoes they engage stop edges 62, 63 on the wipers 60, 61. A stop member 67 prevents the fingers 58 being pushed backwards during lasting. The wiper 60, 61 may be provided with extensions 68, 69 to help to smooth the folds in the lasting margin before the fingers inwipe.
