Abstract: 1,067,484. Moulding ceramic platens. AVCO CORPORATION. May 8, 1964, No. 19262/64. Heading B5A. In a process of making a ceramic platen, a layer of thixotropic siliceous material is vibration troweled on to a master pattern M, allowed to set and then heated to above 450‹ F. The soformed platen may then be used as a master pattern to form a complementary platen, the two platens being used to hold e.g. metal honey comb sandwich panels during brazing. Passages for heating elements and cooling fluid are formed in the ceramic platen during moulding, by cardboard or metal core members (16) or (18) located by guide rails (12) and spacers (17). The platen may be made in stages by using removable transverse rails (13, 14). A release film comprising glass cloth (10) and a plastic film (11) may be used.

Cartons, folding down mouths of after filling. -The apparatus closes and secures the end flaps of cartons, envelopes, &c. by inserting two opposed tongues, 14, Fig. 7, on a flap 13 into corresponding slits 12 in another part 11. In the form shown in plan in Fig. 1, cartons 10 are advanced along a horizontal channel 15 beneath a top plate 16, the flap 11 being turned down upon the contents and the flap 13 turned backwards into the plane of the top of the carton. A conveyer, comprising a bar with fingers 20 moves the cartons intermittently through a channel 18 as described in Specification 324,401, a stationary folder 23 turning the flap 13 over through 135‹. After passing the folder 23, the carton is brought opposite a bracket 25, Figs. 1 and 3, which moves to the left carrying with it a toe piece 24 above the flap 11 and beneath the flap 13. At the same time members 28 are advanced to hold the sides of the carton and a member 29, Figs. 3 and 6, carrying a spring held gripper 31, descends so that the gripper takes up the lower position shown in broken lines in Fig. 3, At the same time, the part-spherical under surface 42 of the member 29 forces a part of the flap 13 to conform to the shape of the toe piece 24 and causes the tongues to point towards the slits 12. Members 43 now descend and press down the tongues and pass through the slits to clear a space in the contents beneath the flap 11. The toe piece 24 and locating members 28 are withdrawn and the members 43 partially lifted with the result that the spring- pressed gripper 31 tends to flatten out the flap 13 and the tongues 14 are thrust into the slits 12. A plunger 45, Fig. 1, discharges the closed carton from the machine.

[Class 40 (v)] The effect of the capacity between a signal-grid and a screen-grid in a multivibrator is minimized by feeding to the latter voltages of the same frequency and phase as those on the former. As shown, the screen grid 34, 36 of each of the tubes of a multivibrator is given an appropriate voltage by a connection to a potential divider 28, 29 or 25, 26 acting as the load resistance of the other tube. Preferably, the time constants of the circuits formed by the potential-divider and grid-circuit resistances and the respective inter-electrode capacities represented by condensers shown in dotted lines are all equal. Preferably, also R26/(R25+R26) is not zero, but is less than Cs/(Cg+Cs), where Cg is the capacity between the signal-grid and the screengrid and Cs is the capacity between the screengrid and all the other electrodes. The invention enables a multivibrator to function at higher frequencies than usual so that it can be used as an amplitude limiter in the I.F. stage of a frequency modulation receiver.
