Abstract: 647,774. Tempering glass. QUENTIN, A. April 30, 1947, No. 11601. Convention date, April 1, 1944. Drawings to Specification. [Class 56] In the tempering of glass a net of tension is made in the core of the glass whereby there results an invisible pattern in the form of a network of supertempered glass which keeps in tempered equilibrium all the other parts which are of lesser temper. This may be done by heating the glass throughout its thickness along a network of spaced zones and then cooling the outer layers whilst temporarily continuing the heating of the inner layers, or the glass may be subjected to uniform preheating and the core maintained at high temperature by heating along a network of spaced zones extending transversely through the glass while the outer surfaces of the zones are subjected to sudden cooling. The heating may be by high frequency induction between electrodes and the cooling jets or suction orifices may be formed in the electrodes. Alternatively the initial heating may be effected in an oven and the glass subsequently passed between electrodes for induction heating of the network, the electrodes also carrying the cooling means.

Title: Improvements in and relating to machines comprising an element arranged to be driven alternately by an open and by a cross belt
IPC: D06F37/36
Filed: 1946-04-16
Abstract: 610,763. Reversing gearing. NAAMLOOZE VENNOOTSCHAP MACHINEFABRIEK REINEVELD. April 16, 1946, No. 11624. Convention date, June 5, 1942. [Class 80 (ii)] In an open and crossed belt reversing gearing for a rotary drum or other machine in which belt guides are constantly reciprocated by mechanism including a clutch mechanism, the belt guides are arranged for relative axial movement and are spring urged apart into engagement with abutments on a reciprocating member in such a manner that on disengagement of the clutch, the action of the spring on the guides moves the reciprocating member to the neutral position. The loose pulleys 12, 13 carrying the open and crossed belts 14, 15 respectively are coaxial with a pulley 4 driving the machine from the fast pulley 11. Rigid with the pulley 12 is a pulley 39 which drives through a belt 38 a worm shaft 36 which rotates a worm-wheel 34 carrying a pivoted lever 32 which oscillates a forked bell-crank 31 pivoted about a shaft 28. A lever 27 is also pivoted about the shaft 28 and carries a weighted pawl 29, which can engage with the bell-crank 31 at its upper end, while the lower end is forked to connect by the pin 26 with the reciprocating member 21a which slides on the rod 21. Movement of the member 21a to the right as shown moves the belt guide 18 by the collar 22 to shift the belt 14 on to the pulley 11 and to compress the spring 24, the belt 14 being wide enough to continue rotation of the pulley 12 and hence the automatic reversing mechanism, which then moves the member 21a in the opposite direction to shift the belt 15 on to pulley 11 by movement of the collar 23 acting on the belt guide 19. Twisting a handle 45 causes the sector 40 to move the bell-crank lever 42, 44 to disengage the pawl 29 from the lever 27, thus allowing the spring 24 to centralize the two belt guides 18, 19 on the member 21a and thus disengage the drive and return the member to the neutral position. Further rotation of the handle 45 allows the pin 46 to clear the edge of the abutment 47 and allow a spring 9 to move the rod 8 and the lever 6 to apply the brake 5 to the pulley 4. If the rod 8 is retained against the spring 9 and further rotated, the finger 41 contacts the projection 25a and moves the member 21a to the left to allow the driven drum to be inched into position by a drive from the belt 15.
