Title: Improvements in or relating to the Manufacture of Solid Rubber Tyres.
IPC: B29D30/02
Filed: 1918-06-22
Abstract: 129,768. Dunlop Rubber Co., Macbeth, C., and Hardeman, W. E. June 22, 1918. Bevelling.-Consists in a machine for bevelling the ends of solid rubber tyres in strip form preparatory to such strips being lap-jointed around their foundation bands. Strips A, supported on roller tracks B, C, are bevelled by a disk cutter D driven as shown and adapted to be swung between the tracks B, C and under a guard P against the action of a spring M by a handle N. The tracks'B, C may be inclined so as to assist gravitationally the feed of the strips. An adjustable stop Q, of a shape corresponding to the cut edges of the strips, serves to position these strips and to determine the position for the bevelling of their rear ends. Specification 128,722, [Class 87 (ii), Moulding plastic &c. substances], and 130,116 are referred to.

Abstract: 659,337. Automatic temperature control systems. BUSER, T., and SAIA AKT.-GES. FUR SCHALTAPPARATE. April 19, 1949, No. 10369. [Class 38 (iv)] [Also in Group XXXVII] A water heater 16 or like device is controlled as to its temperature by means of a temperatureresponsive device 12 and a relay 1, the armature of which after attraction by A.C. in the relay is held set by remanent magnetism and later released by a small A.C. demagnetizing current. When the temperature falls so that the pointer 14 of a temperature-responsive device 12 engages a contact 10 circuit is completed through the coil 1 of the relay causing it to move into its other position in which a circuit to a heater 17 is closed and a circuit to the coil 1 prepared. This circuit which includes a resistance 21 to limit the current is completed when the pointer 14 engages the contact 13 and causes the relay to release.

Patent GB-263376-A (GB)
Title: Improvements in and relating to the reduction of aromatic nitro compounds
Filed: 1926-04-21
Abstract: 263,376. Carpmael, W., (I. G. Farbenindustrie Akt.-Ges.). April 21, 1926. Aminochloramino-, and oxyamino-compounds; aminosulphonic acids; aniline; o-toluidine; a-naphthylamine. - The reduction of aromatic nitro-compounds to the corresponding amino-compounds with iron and a mineral acid is carried out in the presence of an aqueous solution of an aluminium salt, whereby the iron is converted into a finely divided oxide suitable for use as a pigment. The aluminium salt solution may be sufficiently acid, on account of hydrolysis, to render unnecessary a further addition of acid, or the aluminium salt may be produced in situ bv addition of aluminium to the iron. The iron oxide may be used as a pigment either as separated from the reaction mixture or after calcination; its colour varies with the concentration of the aluminium salt in the solution. According to examples, (1) nitrobenzene is reduced with iron and a solution of aluminium chloride, (2) a-nitronaphthalene is reduced with iron and a solution of aluminium chloride acidified with hydrochloric acid, and (3) o-nitrotoluene is reduced with iron and a solution of aluminium and sodium chlorides acidified with hydrochloric acid. In each reaction a yellowish sludge is obtained which on calcination yields a red oxide. The reduction of chlor-, oxy-, amino-, and polynitro compounds and nitrosulphonic acids is referred to.

Title: Improvements in high-intensity magnetic separators
IPC: B03C1/14
Filed: 1961-03-23
Abstract: 919,583. Magnetic separators. SALA MASKINFABRIKS A.B. March 23, 1961 (March 30, 1960], No. 10763/61. Class 117. A high intensity magnetic separator for pulverized ores comprises poles 3, 4 of opposite polarity defining an air gap 5, 20 in which is positioned a stationary or rotatable roll 7 of magnetic material surrounded by a partition or drum 8 of non-magnetic material which is movable or rotatable relative to the roll 7, the roll 7 having ridge-like projections 42, Fig. 3, which may be in the form of a helix, whereby material magnetically attracted to the drum 8 from the ore fed thereto by a feed roller 31 is caused to move or roll on the surface of the drum as it is carried thereby past the ridge peaks 43 through the air gap 5, 20 and thus release any non-magnetic particles which may have been entrapped on the drum surface. The ore is separated into concentrates, mixed discharge and tailings in hoppers 39, 40, 41 respectively. In the arrangement shown in Figs. 1, 3 and 4 the polepiece 4 has a shank 1 which is electrically energized and connected by a frame to the polepiece 3, the roll 7 having helical projections 42 and being supported non-rotatably on a shaft 14 carried by a frame member 9. The drum 8 is rotatably mounted on the shaft 14 and driven by a motor 34 via a belt 33 and a pulley 32. The helical projections 42 impart a lateral component c to the movement of the particles on the drum surface as they are moved past the projections. Figs. 9 and 10 show an arrangement wherein two magnetic rolls 52, 53 each surrounded by a drum 54, 55 respectively define an air space 58 therebetween to which the ore is fed by shoots 59, 60. In this case the rolls rotate, but at slower speed than the associated drum, and they are disposed relatively to each other so that their respective helical projections are in intermeshing alignment as shown in Fig. 9. Each roll is carried by a shaft 67 rotatably mounted in a frame and surrounded by an energizing coil 68, the associated drum being rotatably carried by the shaft and separate driving means being provided for the shaft and the drum. In the arrangements described, the separator assembly of roll and drum may be duplicated at the other end of the pole shank 1, Fig. 1, or the shafts 67, Fig. 10.

Filed: 1940-07-01
Abstract: 542,323. Guiding webs. TOOTAL BROADHURST LEE CO., Ltd., and NIELD, L. C. July 1, 1940, No. 11074. [Class 135] [Also in Groups XVI and XXXV] A guiding member engaging an edge of a web of material is mounted to swivel about a vertical axis and is deflected about this axis by a control co-operating with an edge of the web so as to guide the latter automatically. The control and actuation of the deflection may be mechanical, pneumatic, fluid or electrical. In the construction shown for guiding a web on to stenter chains 27 the control is electrical and the actuation is pneumatic. A guide wheel 3 engaging the selvedge of the web rotates on a spindle 5 carried by an arm 6 on a vertical spindle 7. Fixed on the latter are a vane 8 and brake segment 24 arranged in a cylinder 9 having inlet ports 12, 13, and outlet port 14 for compressed air. The outlet ports 14 are controlled by valves 16 actuated by solenoids 18 which are energized upon the closing of a switch 19 when a finger 20 is deflected by the selvedge of the web. The spindle 7 is thus turned to deflect the wheel 3 whereupon the switch 19 opens. When the switch 19 is open a brake block 23 engages the segment 24 to hold the spindle 7 fixed. The control by the finger 20 may be replaced by any other control such as the interception of a light beam directed upon the field of a photo-electric cell by the selvedge, or by air jets masked by the selvedge. The wheel 3 which is driven by a flexible shaft 29 may be driven at a greater peripheral speed than the stenter chain.
