Title: Improvements in or relating to glass tank furnaces and methods of making glass therein
IPC: C03B5/182
Filed: 1935-05-18
Abstract: 447,228. Glass melting furnaces. HARTFORD - EMPIRE CO., 333, Home stead Avenue, Hartford, Connecticut, U.S.A.- (Assignees of Mulholland, V. ; 26, Sunset Terrace, West Hartford, Connecticut, U.S.A.) May 18, 1935, No. 14632. Convention date, June 13, 1934. [Class 51 (ii)] A glass-melting furnace is divided by a A -shaped weir 12 and a partition wall 21 into melting and refining zones 8, 9 which are separately fired by burners 14 and 24, 25, the firing being so regulated as to provide a region 17 of highest temperature above the weir 12 and a higher temperature along the central longitudinal line of the refining zone 9 than at the sides thereof. This temperature distribution produces a circulation of the glass longitudinally of the melting zone 8 and transversely of the refining zone 9 as shown by the arrows 13, 26 respectively ; in consequence of the general flow towards the working end of the furnace, due to withdrawal of glass, the transverse currents in the refining zone follow helical paths as indicated in Fig. 3. The formation of the different currents in the two zones 8, 9 is assisted by providing insulation for the side walls of the melting zone and not for those of the refining zone. In order to regulate the passage of gas from one zone to the other through the space between the surface of the glass and the lower edge of the wall 21, the pressures prevailing in the two zones are controlled by pressureresponsive devices inserted in apertures 38, 39 and connected to the separate firing systems 14 and 24, 25. The refining zone 9 is separated from a final tempering zone 10 by a bridge wall 27. The weir 12 and the adjacent portions of the side walls of the furnace are constructed as an integral structure without horizontal joints, the side wall blocks 43, which cooperate with the weir blocks 40, being formed, as shown in Figs. 4, 5, with projections to constitute the outer portions of the upper course 12 of the weir.

Title: Improvements in electrical water heaters
IPC: F24H1/20
Filed: 1954-05-19
Abstract: 739,779. Electric water heaters. GENERAL ELECTRIC CO. May 19, 1954 [May 27, 1953], No. 14724/54. Class 39 (3). An electric heater 11 for a water tank 1 comprises two sheathed elements 14, 15 lying in the same plane with one leg of each element in mutual contact, the elements being a snug fit within a tube 13, the walls of which are thin and flexible so that they are forced into intimate heat transfer relationship with the heating elements by the pressure of the surrounding water. The tube is closed at one end by a cap 18 and its outer open end is sealed in an opening formed in the tank wall. To remove a heating element, the water pressure in the tank is relieved by closing a valve in the water inlet 6 and opening a tap in the outlet line 5, the frictional force between the element and the tube walls thus being reduced. A heater 12 is similar to the heater 11 except that only one element 22 is shown. Thermostats 9, 10 are provided. Specification 375,122 is referred to.

Title: Scanning signal processing apparatus for use in the automatic recognition of symbols
IPC: G06V30/164
Filed: 1964-04-13
Abstract: 1,004,019. Automatic character reading. SIEMENS & HALSKE A.G. April 13, 1964 [April 11, 1963], No. 15100/64. Heading G4R. Defects in the printed character cause gaps in the signals as shown in Fig. 2, which are removed (Fig. 3) by the circuit of Fig. 8. The input signals on line n are gated in gate GS 11 with the same signal delayed by a one-bit store SS1. The output is passed, via one-bit store SS11 to one input of blocking gate GS110, the blocking input of which is from line n. Output of gate GS110 passes, via Or gate OGS, to one-bit store S1S110. The input n is also applied to this gate. The output of gate GS110 is also applied, via one-bit store S1v to blocking gate GS1v0 and the output is the blocking input of gate IS1v0. During scanning of column n-2, Fig. 1, the first black is in row m-2. The corresponding signal on line n passes through Or gate OGS and, after a delay of one-bit appears at the output of store S1S110 passing through blocking gate TS1v0 to output w. The black signal from line n produces an output from gate GS11 as there are black signals at points m-2 and m-1. When the scanning spot reaches row m a white signal is produced so that gate GS110 opens, allowing the output from store SS11 to pass via Or gate OGS to store " 1 " in S1S110 ready to take the place of the white signal on line n. If the next signal is black (as in Fig. 1) gate GS1v0 is blocked, giving no output and allowing gate TS1v0 to pass the signal from store S1S110 to output w. The white area in row m of scan n-z is filled in, therefore, by the detection of a " 110 " sequence of which the "0 " is transmitted as a " 1 " if it is followed by a " 1." If it is not followed by a " 1 " signal, a " 0 " is transmitted. Other possible rules are suggested, e.g. that the replacement of a " 0 " by a " 1 " may depend upon being preceded by a group of black signals longer than " 11 " or upon being followed by a black signal somewhere within a larger group of following signals. Breaks in the perpendicular direction as shown in Fig. 4 are filled by a circuit, Fig. 10, having a shift register RZ1 1 which holds a complete column of signals. Corresponding signals from adjacent columns are gated by gate GZ11 and the output entered into another register RZ 11. The presence in three adjacent columns of " 1," " 1 " and " 0 " in the same row is detected by blocking gate GZ110. A following " 1 " in the next column blocks gate GZ1v0 so that output gate TZ1v0 is unblocked at the time the " 110 " signal appears at the output of a further one-column shift register R1Z110. By this means the blank column n in Fig. 5 resulting from the break in the character is filled to produce the signals of Fig. 6. Circuits for filling spaces in a column and for filling spaces across the columns may be combined, a suitable delay being provided to compensate for the different storage periods of the two component circuits.
