Title: Improvements in and relating to continuous rolling mills
IPC: B21B35/02
Filed: 1964-06-10
Abstract: 1,034,955. Rolling mill drives. SCHLOEMANN A.G. June 10, 1964 [July 4, 1963], No. 24037/64. Heading B3M. [Also in Division F2] A continuous rolling mill, suitable for the production of tubes, incorporates a group drive which progressively increases the speeds of successive stands while allowing individual adjustment of each stand within a predetermined range. The output shaft 5 of each stand (Fig. 1, not shown) is driven from a summation drive 4 which combines the inputs from a variable speed D.C. motor 1, a constant speed A.C. motor 2, and a variable transmission 6 for each stand. The output shaft 5, Fig. 2, has three input shafts 7, 8 and 9, the shaft 7 being driven by the variable speed motor from a shaft 12 and bevel gears 10 and 11, whose ratio changes linearly from stand to stand, the shaft 8 being driven by the constant speed motor from a shaft 18, bevel gears 16 and 17, and spur gears 14 and 13, and the shaft 9 being driven from a variable transmission 6 through spur gears 20 and 19. The transmission 6 has a constant speed input from shaft 18 which is adjusted by means of a controller 22. A first planetary gear whose sun wheel and annulus are formed by the shafts 8 and 9, includes planet wheels 24 attached to a carrier 27 which serves as an annulus for a second planetary gear. The second sun wheel 30 is attached to shaft 7 and the planet carrier 25 is connected to the output shaft 5. The variable fundamental speed is supplied by shaft 7, and a modifying constant speed from shaft 8 is superimposed on this speed. The constant speed is modified in turn by the variable transmission 6. The sun wheel 31, planet wheels 24 and annulus 32 may be replaced by an equivalent differential bevel gear.

Title: Improvements in or relating to the production from incombustible fibrous substances of ribbons or strips of insulating material for electrotechnical purposes
IPC: H01B3/48
Filed: 1938-08-17
Abstract: 504,993. Electric insulation; cables. PATENTVERWERTUNGS-GES. HERMES. Aug. 17, 1938, No. 24255. Convention date, Aug. 20, 1937. Drawings to Specification. [Class 36] [Also in Group VIII] Strips or ribbons of insulating material are made by dispersing a mixture of a filler such as quartz meal, heavy spar, magnesium oxide or magnesium carbonate with slag wool or stone wool fibres in a liquid such as water, if desired with the addition of adhesives such as water glass, silica gel, porcelain or marble cements, or cellulosic fibres such as manilla, forming a strip or ribbon therefrom and drying. The dispersion is worked up in a manner similar to papermaking and the strip may be calendered during or after drying. The strips may be wound or spun on to or folded around a conductor and coils produced from such insulated conductors, may be subsequently impregnated in vacuo with aqueous dispersions of ceramic masses such as kaolin, porcelain earth, clay or enamel and baked at a high temperature e.g. 800‹ C. Artificial resin or chloronaphthalene may also be used as impregnants. The strip may be wound to form cylinders which may be similarly impregnated. The strips may be used as insulation in furnace transformers, and may be shaped to provide insulating bushings.

Title: Electro-magnetic testing of steel wire ropes
IPC: G01N27/90
Filed: 1926-10-01
Abstract: 283,256. Wall, T. F. Oct. 1, 1926. Magnetic tests.-A method of testing steel wire ropes &c. for flaws comprises a magnetic circuit system with parallel branches comprising a laminated iron structvre, the common limb of which is surrounded by a coil excited by alternating current, one parallel branch consisting in part of laminated iron and the specimen under test, while the other branch consists in part of laminated iron and a piece of standard rope. In Fig. 1, the exciting coil E is wound round the central limb of a set of laminations L formed from H- stampings riveted together. The rope R to be tested passes through clearance poles in the projecting limbs L<1>L<1> of the stampings. Removable blocks of stampings C may be secured by bolts B to the ends of the limbs. Guide pulleys P are provided for the rope R. In a corresponding position on the other side of the coil E a piece of sound rope D similar to the rope R is fitted, and this may be placed under the same. tension as the rope R. Two search coils S1S1 connected in series are arranged to link with the flux through the rope R, and are connected in opposition to two similar coils S2S2 linking with the flux through the rope D. If the whole system is balanced, the total resultant EMF induced in the coils is zero. If a flaw exists in that part of the rope R in the magnetic circuit, the EMF induced in the coils S, will he diminished and that in the coils S2 increased, and this disturbance of the balance may be measured by means of a voltmeter or ammeter. An amplifying arrangement such as a thermionic valve system may be used in order to detect small flaws. In a modified form there are two series of channel-shaped stampings and two coils excited from the same source. In this form the flux changes occur only in that series through the rope to be tested passes.

The load voltage regulator 9 controls the magnitude of the output voltage E 0  in accordance with the setting of a manually adjustable potentiometer in circuitry 10 which also adjusts for variations in the load whereby E 0  is maintained constant. The regulator 9 is also under the control of circuitry 11 which limits the shortcircuit current of the system. Suitable transistor arrangements for the circuits 5, 9, 10 and 11 are described with reference to Fig. 2 (not shown).

Title: Improvements in a monorail system
IPC: B61F9/00
Filed: 1960-07-13
Abstract: 946,570. Single rail vehicles; undercarriages; monorail railways. S. H. BINGHAM. July 13, 1960 [July 13, 1959; Aug. 28, 1959; Feb. 26, 1960], No. 24473/60. Heading B7L. A monorail car truck comprises a frame, formed of two longitudinal tubular members 2a, Figs. 2, 3 and 4; connected by structural members 2b and 2d and straddling the rail 10; a pair of running wheels 5 journalled on the truck frame on each side of the rail, the planes containing the wheels converging downwardly to a line below the rail; motors 18 and gears 3 carried by the tubes 2a for driving the wheels 5; and a pair of guide wheels 6 on each side of the rail journalled in frame cantilever arms 2c for rotation about vertical axes. As shown in Fig. 4, the wheels 5 engage the lower flange 10a of the rail whilst the wheels 6 engage the sides of the rail web above upper flanges 10b of the rail. The wheels 5 and 6 are provided with pneumatic tyres and thus skid wheels 4 and 9 are provided on the truck frame to engage the top of the web and the sides of the upper rail flanges 10b in event of the tyres deflating. The frame members 2b are connected at each side of the truck frame by an inclined longitudinal structure member 2e. Resting on the members 2e, with the interpositioning of sliding wedge members 12, is a bolster 11 centred between the structural members 2d, Fig. 2, by shock-absorbing elements 13. The ends of the bolster are carried by the centre portions of leaf springs 14 connected on their ends to car body C. Air springs 16 and hydraulic shock absorbers 17 are also provided between the body C and the ends of the bolster and the air springs are arranged in known manner, to maintain a constant clearance between the body and the top of the rail, regardless of the variations of loading of the car. The car body is supported at each end by a similar car truck and the members 2e are inclined downwardly towards the respective car end and upwardly towards the transverse centre plane of the body. When the car negotiates a curve in the rail, the bolsters will automatically slide on the members 2e so that the body will be banked towards the centre of the curve and braking of the rail is thus rendered unnecessary. The wheels 5 each have associated therewith a stabilizing wheel 7, a switching wheel 8 to stabilize the car and to effect switching of the car from one rail to another at switching points as described with reference to Fig. 6 (not shown). The switching and stabilizing wheels may be integral as described with reference to Fig. 7 (not shown), or may be conventional railway wheels to facilitate transfer of the car to a conventional two-rail system.
