Title: Process for the production of hardenable boron-containing synthetic resins
IPC: C08G79/08
Filed: 1961-09-04
Abstract: A hardenable resin is made by condensing with paraformaldehyde a borate of the formula BOx(OR)y, wherein x has a value of from 0 to 1, y has a value of from 1 to 3, 2x+y must always equal 3, and R is a phenyl or cresyl radical.  The reaction may be effected in the presence of a catalyst, e.g. hexamethylene tetramine. The products are soluble in methanol and can be mixed with fillers, e.g. asbestos, to form moulding compositions.  They may also be mixed with phenol-, urea- or melaminealdehyde resins.  In a typical example (1), a mixture of triphenylborate, paraformaldehyde and hexamethylenetetramine was heated to 50 DEG C. and finally at 100 DEG to 110 DEG C. to yield a hard, yellowish-brown resin.  Uses: for making laminates, brake linings and grinding wheels.

Title: A toy with track and vehicles
IPC: A63H18/00
Filed: 1961-09-05
Abstract: 928,904. Toys. A. EINFALT, and J. EINFALT, [trading as EINFALT BLECHSPIELWAKENFABRIK. GEB.]. Sept. 5, 1961, No. 31911/61. Class 132 (3). A toy consists of a closed circuit track 2 having sharp curves and from which branches an approach track 5 from which a plurality of stopping and starting tracks 6 connect with the circuit and self-propelled vehicles 7 each having a drop lever stopping means and a laterally projecting arm 9 with depending pin which can engage guides provided at each sharp corner and at each entrance to a track 6, a vehicle being guided on to the approach track by raising a deflector bar 16 and on to a track 6 by the selective or automatic raising of a plate 23 associated with the guide at the entrance to the respective tracks 6. The tracks are marked on a plate 1. To guide a vehicle along the track 5 a key 21 on one end of a lever 19 pivoted beneath the plate is depressed to raise a lever also pivoted beneath the plate to project the deflector bar 16 at the end of the lever into the track 2. Each lever 19 is integral with an upstanding plate 23 which is raised to engage the pin on the projecting arm 9 of a vehicle and to guide it over a bar 24 with ascending and descending edges to guide it along a track 6. Each track 6 has a stopping recess 15 into which the drop-lever of the vehicle falls to arrest the vehicle. Depressing the key 13 on the end of a pivoted lever 12 raises a plate beneath the recess and lifts the drop-lever to free the vehicle. A vehicle stopped in one track may depress a lever the other end of which projects a plate 23 into an adjacent track to automatically guide the succeeding vehicle into the adjacent track and which succeeding vehicle in its turn raises a plate 23 to guide the next vehicle into the next adjacent track.

Title: Improvements in or relating to rolling mills
IPC: B21B37/18
Filed: 1958-10-10
Abstract: 892,058. Automatic thickness control systems. CANADIAN WESTINGHOUSE CO. Ltd. Oct. 10, 1958 [Oct. 16, 1957], No. 32420/58. Class 38 (4). In an apparatus for reducing the thickness of a material by passing the material through a pair of opposed rolls, the tension in the material and the separation setting of the rolls are controlled by means responsive to the strain in the opposed rolls and the separation setting so as to maintain the reduced thickness constant. In a cold-rolling mill having opposed rollers 2, 3 between which a strip 6 is reduced, and backing-up rollers 4, 5, the upper backing-up roller 5 is slidably mounted in plummer blocks 7 and positioned by a screw-down motor 11 through gearing 10. A signal from a straingauge 13, sensing strain on the backing-up roller 5, is fed to a summating and amplifying circuit 23 and added to a signal from a transmitter 15 sensing the separation setting of the rollers. The summated signal is compared with a signal from a gauge setting circuit 24, representative of the desired thickness, and the resultant error signal is fed to a circuit 25. The circuit 25 comprises a manually-adjustable gate and a manually-adjustable limit circuit. The gate circuit operates the screw-down motor 11 when the error signal exceeds a predetermined value and the limit circuit feeds a signal to a tension controller 21, operating motors 19, 20, when the error signal is below a predetermined value. A signal from a manually-adjustable tension signal generator 22 is fed to the controller 21 to maintain the tension in the strip between predetermined limits. A signal from thickness gauges 26 operates a visual indicator, not shown, or is fed to circuit 23. Either motor 19, 20 operates as a drag generator depending on the direction of travel of the strip. Specifications 681,373 and 692,267 are referred to.
