Title: Improvements in and relating to polymerization processes
IPC: C08F2/22
Filed: 1964-06-29
Abstract: 1,064,164. Reactors for continuous polymerization; continuous discharge mixers. MICHELIN & CIE. June 29, 1964 [June 28, 1963], No. 26884/64. Headings B1C and B1X. A reactor suitable for the continuous production of polymers, for example polyurethane, polystyrene, polybutadiene, polyisoprene, polyisopropylene comprises a vertical tubular reaction chamber, means for feeding reactants upwards through the chamber, and, within the chamber, a roller capable of planetary motion so that it and the wall of the reaction chamber wipe each other. There may be more than one wall-wiping roller, and a further roller may be mounted coaxially with the reaction chamber. In Fig. 1 the reactor chamber 10 having heat exchange jacket 11 contains coaxial roller 25 and symmetrically disposed rollers 26, 27, 28. Reagents enter at 16 and flow upwards past mixing motor 17 (which may be a toothed disc) via opening 22 into the reaction space. The polymer is removed by outlet conduit 44 having impellor 45. The rollers may be driven by the shaft 34, or the reaction chamber 10 may be rotated.

Title: Improvements in or relating to optical systems for observing displacement or deflection in connection with measuring instruments
IPC: G02B23/10
Filed: 1933-09-30
Abstract: 414,239. Telescopes. TEMPLETON, J. C., 10, Copthall Avenue, London. Sept. 30, 1933, No. 26948. [Class 97 (i).] In a telescope equipped with a scale &c. for observing deflections of measuring instruments, light for illuminating a mirror carried by the moving system, such as a magnetic needle, of the measuring instrument, is introduced from the side of the telescope and is directed axially by an inclined reflector within the telescope between the scale and the object glass. As shown, the light is directed laterally into the telescope by a mirror k and is received by the reflector a consisting of a parallel plate of glass. An index d is so situated in the path of the illuminating rays that its image formed by rays passing through the objective e and then reflected back into the telescope by the mirror f of the measuring instrument, lies in the plane of the scale b, this being the common focal plane of the objective e and eyepiece y. Preferably the index d consists of two lines &c. at such a distance apart that, as shown in Fig. 2, an image of one line formed by reflection at the front surface of the reflector a is superposed on the image of the other line formed by reflection at the rear surface of the reflector. The image of the index seen in the field of view then consists of three lines of which the central line is stronger than the outer lines. The distances between the lines in the image are preferably equal to an exact number of divisions of the scale b so that a reading can be taken even when the central line is out of the field of view.

Title: Improvements in mercury treadle electric switches used on railways
IPC: B61L1/04
Filed: 1924-11-12
Abstract: 237,473. Siemens Bros. & Co., Ltd., and Ferreira, L. de M. G. Nov. 12, 1924. Pneumatic actuation.-In a switch of the mercury treadle type which is operated by the passage of a railway vehicle, the contact-operating float is prevented from sticking by being constrained to move about a pivot. As shown in Fig. 1, pressure on the treadle diaphragm 1 which is placed beneath a rail forces mercury from the reservoir 1<a> through an opening 6 and ball valve 9 into a float chamber 15. The float 22 is attached to pivoted arms 19 carrying contacts 23 co-operating with fixed contacts 31. The float is formed as a solid of revolution with its surface 22 concentric with the pivot pin 21, the chamber 15 being similarly formed so that s small clearance may be employed. Mercury drains out slowly through a hole 16. Any excess of mercury entering the float chamber is deflected by the surface 35 into the chamber 2 from which it passes by way of the ball valve 13 and opening 7 into the reservoir 1<a> when pressure on he treadle 1 is released. The contacts mav alternatively be broken when the float is raised.

Abstract: 847,262. Dental engines. DENTISTS'SUPPLY CO. OF NEW YORK. Aug. 29, 1957 [Jan. 18, 1957; Aug. 22, 1957 (2)], No. 27269/57. Class 81(2) [Also in Groups XXVI and XXXIV] The burr or tool 116, Fig. 4, of a dentists' handpiece is driven by a miniature air turbine housed in a head 28 obout 0À5 inch long and 0À375 inch outside diameter and carried by a metal tube 82 inserted in a handle 24. The turbine comprises a rotor 36, Fig 5, having integral blades 86 and upper and lower collars 74, 76 which serve to space the air-cooled ball bearings 38, 52 supporting the rotor. The outer race 42 of the lower bearing fits into a recess in the head 28 and is held in place by a threaded ring 48 having, in addition to its control bore, air outlet ports 134, while the outer race 58 of the upper bearing is a press fit in a flanged collar 60 held in place by a cap 62 screwed into the head and having an air outlet 78. The inner races of the bearings are press fits on the rotor 36 which has a threaded bore containing a plain nylon sleeve 114 the outer surface of which is pressed into the thread of the bore by the insertion of the shank of the tool 116. The turbine is driven by compressed air supplied through a tube 96 seated in a recess 82, Figs. 10, 11, in a plug 84 at the end of the tube 82 and communicating with an eccentrically disposed bore 86 which directs a tangential jet of air on to the turbine blades, the air being exhausted mainly through an axial slot 88 in the plug into the lower end of the tube 82 which is closed by a disc 100 having an air outlet port 106 which maintains a desired back pressure in the tube. The remainder of the air exhausts through the opening 78 in the cap 62 and inclined ports 80 in the bottom wall of the head after passing through the ball bearings. The air issuing through the ports 80 is directed on to the tool 116 together with a stream of water issuing from a jet tube 92 supplied through a tube 98 sealed in a second bore 90 in the plug 82. In assembling the turbine, the lower bearing is inserted in the housing and the 48 screwed home whereupon the rotor 36, with the upper bearing and the collar 60 mounted thereon, is pushed into the housing so that the rotor extends through the inner race of the lower bearing. The parts are held in place by the cap 62. In a modification, the turbine 218, Figs. 19, 20, its flanged casing 230, the upper and lower bearings, and a flanged collar 228 form a unit that is readily insertable in or removable from the housing. The casing is formed with air inlet and exhaust ports 276, 288 respectively. Numerous modifications in the constructial details of the turbine casing and bearings are described.
