Title: Apparatus for producing sheet glass
Inventor: ZELLERS JAMES THOMAS
IPC: C03B15/04
Filed: 1961-11-11
Abstract: A device for controlling the temperature of the molten glass in the forming chamber, particularly of a Colburn type glass sheet forming apparatus, and which reduces the possibility of turbulant waste gas interference, consists of a hollow sectionalized "lip-tile" of refractory material, e.g. silicon carbide, extending transversely across the forming chamber closely adjacent to the molten glass surface and fixed close to the end wall of the cooling section of the tank furnace, with means provided for cooling or heating the interior of the tile.  The lip tile consists of a U-shaped elongated member 34, Fig. 4, with side walls 40, 41 and bottom wall 42, constructed of interlocking sections.  A tubular hanger member 35, Fig. 1, which bodily supports the tile in its operative position, forms the top wall of the tile by engagement of its undersurface in the lugs 43 of the tile.  The hanger member 35 is adjustably supported by rods 48 from the roof of the drawing chamber. The interior temperature of the tile is influenced by burner flames introduced through ports 59 <PICT:0999305/C1/1> in the walls of the chamber, which also serve as waste gas escape ports.  Alternatively, cool air may be blown into the tile through pipe 61 (Fig. 2, not shown), which terminates intermediate the ends of the tile.  In an alternative embodiment, the lip tile comprises an open-ended sectionalized refractory block adapted to receive a U-shaped panel to close the lower end, and suspended by a plate on the underside of the top wall screw-attached to a tubular horizontal bar on the top outerside, the engaging surfaces being separated by heat resistant material, e.g. asbestos. The bar has means for suspending it by rods from the roof of the forming chamber.

Abstract: 1,163,545. Automatic exchange systems. TELEFONAKTIEBOLAGET L. M. ERICSSON. 14 Sept., 1966 [4 Sept., 1965], No. 41156/66. Heading H4K. A time division multiplex switching network serving N lines in groups of n by means of highways having t time slots comprises a Pxn matrix of gates for each group of n incoming channels giving each group access to P tdm highways, each such highway comprising a row of a correspondingly separate intermediate stage matrix, of which there are consequently P, a Pxn matrix of gates being provided for each group of outgoing channels making each group accessible to a column highway from each of the intermediate stage matrices, the number of tdm highways serving each group which is the same as the number P of intermediate stage matrices being chosen to give the least number of matrix cross-point gates in the system. It is shown that the value of P corresponding to the least number of gates is given by #2N/t. A four-wire system is described having 2048 lines switched over highways with 32 time slots. To be non-blocking the Pxn matrices serving each incoming and outgoing group of n lines provides 2n channels to the intermediate matrices. If there are 16 lines in each group a single highway is sufficient to serve each group and there is consequently a single 128 x 128 intermediate highway switching matrix giving a total of 20,480 matrix gates. If there are 48 lines in each group three highways are sufficient to serve each group, there being three intermediate highway switching matrices and a total of 17,835 matrix gates. However, if there are 32 lines in each group two highways are sufficient to serve each group with two 64 x 64 intermediate highway switching matrices giving a total of 16,384 matrix gates which is less than either of the preceding cases and satisfies the requirements of the invention. The system is controlled by a common processor, each highway on the outgoing side having two stores of 32 compartments each, one store controlling the gates between the highway and the outgoing lines and the other store controlling gates between that highway and the other highways to which it has access over the intermediate matrices. A separate store is provided for each highway on the incoming side to control the gates between these highways and the incoming lines. Some of the four-wire terminals serve registers with direct links to the processor which determines free routes across the network.

Abstract: 1524752 Electronic alarm watches DAINI SEIKOSHA KK 7 Oct 1976 [13 Oct 1975 (2)] 41755/76 Heading G3T In an electronic alarm watch with a digital display, means are provided to prevent a display illumination means and the audible alarm means being in an energized state at the same time, the alarm means being given priority. Battery drain is thereby minimized. In Fig. 1, an alarm device 10, e.g. aural, is driven by a circuit 9 when a coincidence circuit 3 detects coincidence between the actual time of day count in a counter 2 and the pre-set alarm time in a counter 5. A light-emitting device 14 for illuminating the display is driven by a circuit 13 via a NOR gate 11 when a switch 12 is closed to a supply terminal H - provided the alarm is not activated, in which case the NOR gate 11 blocks the output of driver circuit 13. In an alternative embodiment Fig. 2 (not shown) the set and reset outputs of a flip-flop (17) respectively cause energization of an audible alarm device and a display illuminating means so that simultaneous energization is avoided. An output pulse from the timekeeping counter resets the flipflop after a predetermined period thereby terminating the alarm. The resetting can also be effected by a manually operated switch so as to stop the alarm.  In both embodiments, a changeover switching circuit 6 permits display of either the time of day or the pre-set alarm time.
