Title: Improvements in rolling mills
IPC: B21B13/14
Filed: 1960-04-11
Abstract: 889,916. Rolling. MOELLER & NEUMANN G.m.b.H. April 11, 1960 [April 11, 1959], No. 12780/60. Class 83 (4). In a multi-roll mill including work rolls 1, 1<SP>1</SP> each supported by intermediate rolls 2 which are in turn supported, in part through a centre roll 4, by outer support rolls 5, 6, a further intermediate roll 3 is included between the centre roll 4 and the intermediate rolls 2 to reverse the direction of rotation of the centre roll 4 so that the rotation of all rolls in contact with the support rolls is the same and a solid construction can be used for the latter to facilitate driving. The work rolls 1, 1<SP>1</SP>, the intermediate rolls 2 and the centre rolls 4 are freely floating in a lateral direction and are merely retained axially by a cover plate. The intermediate roll 3 is supported in end bearings which are guided for laterally restricted movement in the workroll plane. In this manner escape of the free rolls due to unbalanced frictional forces e.g. of rotation and reeling is prevented. The support rolls have fixed bearings and may be supported at the ends only or at additional points intermediate the ends. If the work rolls are of very small diameter the intermediate rolls 2 must also be of small diameter so that the centre of each roll 2 may be within the angle α to prevent escape of the free rolls. The rolls 2 are then too small to take a direct drive and the support rolls 5, 6 must be driven. The support rolls are then either solid rolls with a continuous cylindrical surface or have intermediate divided bearings accommodated in ring grooves in the rolls. The gear drive includes three gear-wheels so that the direction of rotation of rolls 5 and 6 is the same. If the work rolls and intermediate rolls 2 are sufficiently large the rolls 2 may be driven in which case the support rolls may either be constructed as before or may comprise freely rotatable sections spaced along a stationary spindle. Rolls 1, 1<SP>1</SP>, 2 and 4 are exchangeable and the support rolls 5, 6 may accordingly be adjusted towards the rolling plane. Specification 826,000 is referred to.

Title: Improvements in and relating to the production of dried products from latex
IPC: C08C1/12
Filed: 1952-05-28
Abstract: A process for obtaining dried products from the latex of a neoprene or butadiene-acrylonitrile or butadiene-styrene synthetic rubber comprises changing the isoelectric point of the particles in the discontinuous phase by adding a surface active agent and then increasing the charge density of the particles by adding an acid salt or the like ionizable compound, and drying the mixture.  The surface active agent may be an anionic or a cationic wetting agent such as cetyl pyridinium chloride.  The charge density may be increased by an acid such as lignin sulphonic acid or a salt such as ammonium chloride or ferrocyanide. Alternatively an alkali may be added after an anionic wetting agent.  The surface of the rubber particles may be rendered less sticky by the addition of quinones and ferric sulphate, sodium perborate and mercuric chloride, or hexamethylene tetramine, thiolacetic acid or polyethylene glycol.  Fillers such as carbon black, zinc oxide and infusorial earth may be added in emulsion form or directly, but independently, into the drying chamber while the latex is dried.ALSO:A process for obtaining dried products from natural or synthetic rubber latex comprises changing the isoelectric point of the particles in the discontinuous phase by adding a surface active agent and then increasing the charge density of the particles by adding an acid salt or the like ionizable compound, and drying the mixture.

Filed: 1939-04-29
Abstract: 528,203. Portable turning-apparatus. SHOESMITH, H. W. April 29, 1939, No. 12886. [Class 83 (iii)] A manually-operated pipe-cutting tool comprises a C-shaped frame 12 mounted on an operating-handle 11 and carrying four pairs of rollers 15 and a rotatable toothed cutter 26 which is of gradually increasing radius and is rotated to feed the cutter into the work by a slight swinging of the handle 11 round the work in one direction, the cutting being effected by swinging the handle in the opposite direction during which the cutter remains stationary relative to the tool. The cutter is mounted in a slotted frame 18 having a stem 17 passing through the handle and carrying an axiallyfixed sleeve 22 which may be screwed over the threaded part 23 of the handle to adjust the frame to and from the work 35. A pair of serrated discs 34 engaging the work are connected by reducing gears 31 to the cutter spindle. By rotating the sleeve 22 the discs are moved up to grip the pipe while the cutter touches the pipe at its smallest radius. The handle is then swung anti-clockwise to a small extent during which movement the discs are rotated and the cutter fed into the work. The handle is then swung clockwise for the cutting operation, whereupon the discs slip over the pipe and the cutter is not rotated. Further feed movement can then be applied by successive short anti-clockwise rotations until the pipe is severed. In a modification the discs 33, 34 may be friction wheels provided with free-wheel devices.

Title: Improvements in or relating to amplifying systems
IPC: H03F1/36
Filed: 1945-05-24
Abstract: 601,990. Preventing acoustic reaction. SPERRY GYROSCOPE CO., Inc. May 24, 1945, No. 13017. Convention date, May 26, 1944. [Class 40 (iv)] In an amplifying system such as is used in public address systems or in a loud-speaking telephone, build-up due to acoustic reaction is prevented from causing " howling " by periodically reversing the phase of the output at a sub-sonic frequency. Speech signals from microphone amplifier 36 are applied to the grids of valves 19, 21 which are rendered alternately conducting and non-conducting by the application of alternate positive and negative voltage to their grids so that only one valve conducts at a time. These biassing voltages are obtained via transformer 27 from a square-wave generator consisting of a sine wave generator 17 and a limiter 18. The outputs from the valves are coupled to the output amplifier 13 by transformer 23. If desired, by the application of suitable biassing voltage to limiter 18, the duration of connection in one phase may be made longer than that in the other phase. The corners of the square wave may be slightly rounded off to prevent " key-clicks." The Specification as open to inspection under Sect. 91 states that the frequency of reversal may be supersonic. This does not appear in the Specification as accepted.

The ratchet mechanism may be releasable to allow rotation in either direction. The free end of each limb may comprise a freely rotatable roller 30 which is adjustable towards and away from the axis to vary the effective length of the limb. Each limb of the control member may have a pair of side frames (42 Figs. 2 and 3 not shown) which are divergent in the direction of rotation of the limb so that the side frames wedge onto the animal. Alternatively each limb may include a pair of side frames (46 Figs. 4 and 5 not shown) which are rotatable to a limited extent about a vertical axis and wedge onto the animal. The passageway may be defined by an animal race or a handling or weighing crate.
