Patent GB-774608-A (GB)
Title: A process for the preparation of aromatic carbonyl compounds from aryl ethylenes
IPC: C07C51/16
Filed: 1955-03-03
Abstract: Aromatic aldehydes or ketones of the type <FORM:0774608/IV(b)/1> are prepared by oxidizing aryl ethylenes of the type <FORM:0774608/IV(b)/2> (i.e. in which the ethylenic linkage is conjugated with the aromatic nucleus) with manganese dioxide or a hydrate thereof in an aqueous medium and in the presence of an acid which is stable under the reaction conditions.  One or more other oxidizing agents, such as a dichromate, may be present in addition to the manganese dioxide.  Compounds known to inhibit the oxidation of the aldehydes or ketones may also be present.  Such compounds may be aromatic aminosulphonic acids such as sulphanilic acid or acid-resisting dispersing agents.  The aryl ethylenes may be mono- or poly-substituted in the side chain and/or the aromatic nucleus by alkyl-, aryl-, aralkyl-, alkoxy-, methylene-dioxy-, aralkyloxy-, aryloxy- or acyloxy-groups or by halogens.  The oxidation may be effected by adding dilute mineral acid to a mixture of the compound to be oxidized, the oxidizing agent and water at an elevated temperature.  The manganese dioxide may be in the form of pyrolusite, or may be manganese dioxide obtained by reacting a permanganate with a manganese salt, or obtained as a byproduct from a permanganate oxidation in an alkaline medium. Examples illustrate the oxidation with manganese dioxide and aqueous sulphuric acid of (1) methyl-isoeugenol to veratric aldehyde; and (2) anethol to anisaldehyde, both in the presence of sulphanilic acid; (3) styrene to benzaldehyde and some benzoic acid; (4) a -methylstyrene to acetophenone and some benzoic acid; and (5) b -methyl styrene to benzaldehyde and some benzoic acid; (6) anethol is oxidized to anisaldehyde with pyrolusite in the presence of sulphuric acid and of sulphanilic acid; and (7, 8) methyl-isoeugenol is oxidized to veratric aldehyde by a mixture of manganese dioxide and sodium dichromate in the presence of sulphuric acid and sulphanilic acid.

Title: Improvements in or relating to filter elements
IPC: B01D46/52
Filed: 1968-02-08
Abstract: 1,221,310. Cutting apparatus. SOC. INDUSTRIELLE DE FILTRATION. 8 Feb., 1968 [8 Feb., 1967], No. 6312/68. Heading B4B. [Also in Division B1] A machine for making transverse part-cuts (e.g. 9b) in a longitudinally fed panel 5a is disclosed in connection with the manufacture of filter elements (see Division B1). It comprises a rotary cutter 36 able to reciprocate along a transverse carrier rail 26b (i.e. towards you out of Fig. 12). During the return stroke the panel 5a is fed, so cutter 36 must be tilted out of contact with it, as shown. This is achieved by a roller 67 which is held down by a guide bar 66. At the end of the cutting stroke roller 67 passes over an escapement device 68 pivoted at 69 to the end 66b of the guide bar (Fig. 16); at the beginning of the return stroke it passes under device 68 and hence under guide bar 66. During the cutting stroke a member 37 skis across panel 5a, thus supporting blade 36 at the correct level (which is adjustable, Fig. 13, not shown). The cutter assembly is reciprocated by a chaindrive 30, see also Figs. 8, 10, 11 (not shown). Electric and pneumatic circuits are disclosed for programming the device, Figs. 18 and 19 (not shown). To enable feeding to continue during cutting, the guide bar 26b is mounted at an adjustable small angle to the transverse direction, Fig. 7 (not shown). In practice, cuts 10b are simultaneously made in the underside of panel 5a by a similar reciprocating cutter assembly mounted beneath (Fig. 6, not shown).

Title: Improvements in and relating to synchronous commutator motors
IPC: H02K19/04
Filed: 1931-03-02
Abstract: 384,640. Alternating-current motors. INTERNATIONAL GENERAL ELECTRIC CO., Inc., 120, Broadway, New York, U.S.A.-(Assignees of Allgemeine Elektricitats-Ges.; 2, Friedrich Karl-Ufer, Berlin.) March 2, 1931, No. 6479. Convention date, March 1, 1930. Void [Published under Sect. 91 of the Acts]. [Class 35.] A synchronous motor is constructed as a commutator motor which can be supplied with alternating or continuous current and the armature and pole shoe laminµ are so constructed that the stator field has a substantially wave-like form. In Fig. 1, the armature a and the poles g are formed with a number of teeth z such that the machine runs synchronously. In order that the motor shall start in all positions of the rotor, the arrangement shown in Fig: 2 may be adopted. The stator slots f accommodate an alternating current winding and the field coil e and armature winding may be fed with continuous current. If the number of rotor teeth to give a required speed is too small to allow of satisfactory commutation, a larger number may be grouped in twos, so that each group has the character of a pronounced projection. If the required number is very large, each armature tooth may be formed with one or more indents so that the total number of projections is a multiple of the number of armature teeth. The winding in the slots f may be fed with alternating current derived from a continuous current source and it may be connected in series with the motor winding, shunt resistances being used to obtain the necessary proportion of the synchronizing and motoring torques.

Filed: 1919-03-20
Abstract: 124,742. Soc. des Anciens Etablissements Weyher et Riohemond. July 6, 1914, [Convention date]. Starting; reversing. - The valve-levers 3 are pivoted on eccentrics 4, Figs. 1 and 2, keyed obliquely on an adjustable shaft 5, and are adjusted to engage forward and reverse cams 9, 11 by turning the shaft 5 through 180 degrees and displacing it axially at the same time. This adjustment is effected by a shaft 33 carrying a gear wheel 35 and cranks 34. The valve-levers are held against the valve-sterns by springs so that, during adjustment, the cam-bowls are raised clear of the cams. As applied to a Diesel engine, similar gear is provided for the admission, exhaust, and fuel valves. The starting-valve 22, Fig. 4, is worked by an inclined lever 30 pivoted at 31 and connected by a rod 29 with the axially adjustable lever 24 which engages forward and reverse cams 26, 27. The pivot 31 of the lever 30 is depressed by projections 32, 32<1> on a cam 23 on the shaft 5 in order to bring the cam-bowl 25 into an operative position when in alinement with one of the starting cams. This position is reached before the shaft 5 is moved fully into the running position; the fuel valve is not yet in action, but the inlet and exhaust valves are in operation with reduced opening. When the engine gathers speed, the shaft 5 is moved to the running position and the starting valve-lever moves out of range of the starting cams. For an engine with six or more cylinders, the gear described above is designed so that the engine will start in any position. In other cases, an auxiliary cam 41 is provided for admitting compressed air to that cylinder which is on the suction stroke, .so as to turn the engine to the starting position. This cam is between the forward and reverse starting cams, and a projection 40 is provided on the cam 23 to bring the cam-bowl 25 into range of the cam 41. A special valve controlled by the movement of the shaft 5 is provided for exhausting the compressed air from such cylinder before starting.
