Abstract: 1,172,052. Apparatus for forming recesses in thermoplastic films. O. HÍFLIGER, and R. KARG., [trading as HÍFLIGER & KARG]. 25 Jan., 1968 [25 Jan., 1967], No. 3927/68. Heading B5B. The peripheral surface of a rotatable metal drum 1 (Fig. 1) is provided with recesses 2 (Figs. 1 and 2) communicating via openings 6 with passageways 5. As the drum rotates the passageways 5 are periodically brought into communication with a slot 7 in a stationary ring 8 on which one end face of the drum slides and which communicates via a pipe 9 with a source of vacuum. In the same way the open ends of the passageways 5 periodically pass a slot 10 in the ring 8 which slot communicates via a pipe 11 with a source of pressurized air. The periphery of the drum is provided near its edges with a row of recesses 12 communicating via bores 13 with the passageways 5. The internal surface of the peripheral wall of the drum is provided with cooling fins 14. In operation the film 16 after being passed on to the peripheral surface of the drum passes through a zone 17 in which the film is heated to render it deformable. The film then passes over a portion of the peripheral surface of the drum in which the recesses 2 are in communication with the source of vacuum via the slot 7 whereby the portions of the film covering the recesses 2 are drawn into the recesses. At the same time the portions of the film covering the recesses 12 which are also in communication with the vacuum slot 7 is brought into air-tight engagement with the periphery of the drum and areas of the film covering the recesses 2 are drawn into the recesses and recesses are formed in the film Further rotation of the drum causes the deformed embossed portion of the film to leave the zone of the slot 7 and the embossed film is thereafter withdrawn from the drum. Thereafter the hot portion of the drum periphery moves through the zone of the slot 10 where the passageways 5 and recesses 2 are cooled by compressed air from the slot 10.

Filed: 1930-02-06
Abstract: 348,078. Changing signs. TUGWOOD, R. J., 77, Chancery Lane, London.-(Ussing, O. ; Rhane Street, East Rockaway, Long Island, New York, U.S.A.) Feb. 6, 1930, No. 4070. [Class 3 (i).] In changeable signs comprising a row of independently operated display bands mounted on rollers, means to prevent the turning of any roller in the wrong direction consist of a ratchet wheel 55 rigidly fixed on the roller spindle 52 and engaged by a spring-pressed pawl 57 carried on an arm 56 pivoted about the spindle 52. A lip 60 enables the arm 56 to be manually turned in one direction, and a spring 61 riding round a segmental rib 64 on the arm restores the arm to its initial position, repeated actuation of the arm effecting rotation of the roller and bringing the band to any desired display. At the initial position the pawl 57 is withdrawn from the ratchet 55 by an abutment 65, thus allowing the roller to unwind when the opposite roller is being operated. Fig. 12 shows a method of inserting the rollers 51 between the frame members 34, consisting of a spindle stud 53 which is axially movable against a spring 54. A braking action is thus provided which maintains the band taut. The roller housings are connected together by a band backing member 37 which guides the edges of the travelling band. The roller and band elements are mounted side by side on a casing 20, Fig. 4, which is narrowed at its front to take between the roller housings of the elements. The elements are held in registered position by an apertured and glazed cover 22 having spring side wings 27 which take over studs 23 on the casing 20. A sheet of glass 66 is held in place by rods 71 at the front of the casing, and lamps 47 within are mounted on a chamber 69 formed by upturning a lining 67 of the casing. Ventilation openings 76a, 77 are provided, and a door 74 gives access to the interior and allows the sign to be employed for illuminating purposes. The device may be suspended by hooks 78 or be mounted on brackets supporting the studs 23.

Title: Annealing of glass
IPC: C03B25/12
Filed: 1963-02-04
Abstract: In annealing glass by cooling through its annealing range, the glass is continuously cooled from the upper limit to the lower limit, of the annealing range in a plurality of finite steps of successively different, substantially constant positive cooling rates as R1, R2, R3 (Fig. 9, no shown).  Initial cooling R1 is preferably rapid, R2 rate substantially less and final rate R3 again increased.  Rate R1 is obtained by water coolers 32 adjacent each side of the glass ribbon as it is drawn into the annealing lehr, with the terminal portion 321 inclined towards the ribbon to prevent influence of heat from following burners 34 which retard the normal cooling rate to give the second rate R2.  The third rate R3 may either be obtained by further coolers or, as in Fig. 9, by doors 37 opened to increase the cooling rate.  The heaters 34 may be in three sections across the width of the ribbon for better control of the temperature of the ribbon edges.  The following composition is given in weight percentages: SiO2 71.38; Na2O 12.79; CaO 9.67; MgO 4.33; Na2SO4 0.75; NaCl 0.12; Fe2O3 0.15; Al2O3 0.81.
