Title: Improvements in and relating to the manufacture of sulphones
Filed: 1942-10-23
Abstract: An a -halogencarboxylic acid or a functional derivative thereof is condensed with a salt of a benzenesulphinic acid containing a para amino or substituted amino group.  The carboxylic acid may belong to the aliphatic, araliphatic or aromatic series.  By continuing to heat the reaction products or by using a salt of the a -halogen carboxylic acid, decarboxylation is effected.  In examples: (1) p-acetylaminobenzenesulphinic acid is condensed with chloracetic acid in the presence of caustic soda and the product hydrolysed to P-aminobenzenesulphonyl acetic acid; (2) the reaction products obtained in the previous example are heated under reflux and evaporated to dryness; by extracting with acetone, p-acetylaminobenzene-sulphonylmethane is obtained; (3) sodium p - acetylaminobenzenesulphinate is condensed with ethylchloracetate in xylene or amylalcohol containing a trace of copper and the product hydrolysed and decarboxylated; (4) potassium p - acetylaminobenzenesulphinate is condensed with chloracetonitrile and p-aminobenzenesulphonacetonitrile obtained by hydrolysis.  The latter yields p-aminobenzenesulphonylthioacetamide when treated with hydrogensulphide while suspended in ammonia solution and p-aminobenzenesulphonylacetamidoxime when treated with hydroxylamine. Samples have been furnished under Sect. 2 (5) of products obtained by condensing sodium p-acetylaminobenzenesulphinate with ethyl-a -brompropionate and potassium p-acetylaminobenzenesulphinate with chloroacetonitrile and also with ethyl-a -brombutyrate.

Filed: 1938-05-23
Abstract: 512,274. Milling cutters; reamers; boring- heads. MILLER, F. P. May 23, 1938, No. 15335. [Class 83 (iii)] An inserted blade cutter such as a milling- cutter, reamer, boring-head &c. has the blade 12 secured in slots in the body 10 by a threaded plug 17 engaging in a tapered screwed socket the pitch line E of the socket thread being parallel to the socket axis, the plug also having a tapered thread with a pitch line parallel to the plug axis, the diameter of the plug being slightly less than that of the socket so that the plug contacts the blade and the socket at diametrically opposite points. The blades 12 may be longitudinally adjusted by a collar 14 and locking member 15. Threaded bores 16 of the sockets break into the blade slots and have their axes inclined to the blade surface at an angle C, preferably from 3-5 degrees. The threads are formed by tapping a cylindrical hole with the leading portion of a tap having uniform pitch and a cylindrical pitch surface but having the tops of the threads cut away along a line inclined at an angle D to the bore axis. The screw plug 17 is of slightly less diameter than the bore and is made from a screw of cylindrical surface by grinding off tops of the thread to the taper angle D of the tap used in forming the screwed bore. When the screw plug, which has threads slightly deeper than those of the socket, is assembled, it bears at diametrically opposite points against the blade 12 and against the wall of the socket, the bearing surfaces formed by the flattened tops of the screw thread and the bottoms of the socket thread progressively increasing towards the inner end of the socket.

Title: Improvements in rotary internal combustion engines
IPC: F02B53/00
Filed: 1935-05-28
Abstract: 457,467. Rotary engines. GUINNESS, E. E., c/o Fluvario Co., Sedgley Road West, Tipton, Staffordshire, and ELWELL, M., The Laurels, and ELWELL, W., The Chequers, both in Tipton Road, Woodsetton, Staffordshire. May 28, 1935, No. 15480. [Class 110 (ii)] An internal-combustion engine comprises a rotor 2 having peripheral recesses to accommodate roller vanes 4 (or sliding vanes), and a distributer valve 7. Gas is supplied to an inlet 9, compressed through a passage 10 to the inside of the valve, and enters a working space by way of a passage 11. The gas is fired by a plug inserted in a hole 13, expands, and is exhausted through a port 8. The rotor may be cooled internally through the hollow shaft which leads to and from an annular space 17. Recesses 2a provide pockets to receive the force of the expanding gases. Cams 6 guide the inside of the vanes, and are lubricated from external ducts. The sides of the rotor may have concentric rings co-operating with grooves in the side walls, to form packing rings. A supercharger may be fitted to the inlet 9. A port 8a allows further exhausting of the gases. In a modified arrangement, the charges may be fired in spaces on opposite sides of the rotor, separate distributer valves being fitted for each working space, the valve being supplied directly from a compressor.

Title: An improved electric regulator
IPC: G05B11/01
Filed: 1946-05-22
Abstract: 640,503. Automatic temperature control systems; inductances. LANDIS & GYR SOC. ANON. May 22, 1946, No. 15505. Convention date, May 28, 1945. [Classes 38 (ii) and 38 (iv)] An electric regulator, Fig. 1, for correcting changes in a physical quantity, e.g. temperature, comprises an element 4 sensitive to changes in the quantity, an inductive unit 1-3 variable by the element 4 and a second similar unit 5-8 which is present in accordance with the quantity to be controlled and is also responsive to an anti-hunting control. A change in the magnitude of the quantity to be controlled varies the air-gap of the unit 1-3, the coils 1, 2 of which are connected in series with the coils 5, 6 of the unit 5-8, so as to unbalance the normally balanced watt-meter relay 9-13, and cause a disc 12 to operate contacts 17 and energize one or other of relay coils 19 or 20. Assuming the coil 19 is energized, closure of the relay contacts causes (a) energization of a holding circuit for the coil 19 over contacts 221, (b) energization of heating windings 16a on the unit 5-8 to form a thermal feed-back device for preventing hunting; (c) connection of a regulating device 18 to the supply a, b; (d) insertion of a resistance 23 for damping the watt-meter to prevent hunting thereof; and (e) energization of a motor 22, adapted after a predetermined time delay to actuate contacts 223 to stop the regulator 18, contacts 222 to de-energize the heater windings of the element 16a, and changeover contacts 221 to de-energize the coil 19 and prepare the holding circuit of the coil 20. As shown in Fig. 3, the feed-back device on the unit 5-8 comprises two fixed cores 37, 38 mounted on rods 42, 43 and an armature 39 which may be adjusted by a knob 30 or by the action of the feed-back device. The latter comprises two brass tubes 27, 28 mounted at one end on a  fixed plate 26 and carrying a plate 29, supporting the knob 30, at the other end. The end of the knob bears on a plate 32 attached .to two brass tubes 33, 34 joined by a plate 35 which carries, on a rod 36, the armature 39. The brass tubes 27, 28 ami 33, 34 have heating windings which are respectively energized by the closure of the contacts of relays 20, 19. Expansion upon heating causes the armature to be moved to introduce a control which compensates for over-regulation, after a deviation in the quantity to be controlled has occurred. In a second embodiment (Fig. 2, not shown), on-off regulation is obtained by dispensing with one of the relay coils 19, 20, and employing in the feed-back device only one pair of heater tubes. Instead of using inductive units 1-3, 5-8, variable condensers may be employed. Speci. fications 609,484 and 633,753 are referred to.
