Title: Improvements in and relating to furnaces
IPC: F23M5/08
Filed: 1926-03-22
Abstract: 249,560. Bailey, E. G. March 20, 1925, [Convention date]. Composite tiles. - A water-tube boiler furnace fired by liquid, gaseous of pulverulent fuel is enclosed by rows of water tubes to which are clamped special tiles, the construction of which varies in different Darts of the furnace. At those parts of the iurfurnace where it is desired to maintain the highest temperature the tiles are formed with an inner face of refractory material and an outer covering of metal, preferably cast iron, while the tiles which are adjacent to or form the floor of the furnace are made of cast iron only. Fig. 4 shows portions of the front and side walls of the furnace with vertical and horizontal water tubes 20, 30 respectively. The metal portion 51 of the tiles is provided with projections 52 which interlock with the refractory portion 50. Each tile is provided with recesses 53 to fit the tubes to which it is secured by bolts 55 and clamping members 56. In order to ensure good conduction between the tiles and the tubes and to form an air-tight joint a cement such as a compound of carborundum water glass and glycerine is applied between the surface of the tubes and the tiles and clamping members. Sufficient space is maintained between the tiles to allow for expansion. The tiles are made by placing the refractory face portion in a mould 60, as shown in Fig. 6, and running the metal into the space 61.

If it is desired to handle a load on the left side of Fig. 3 and if the operative pair of forks 231, 232 are pointing straight ahead as shown in solid lines the carrier plate 77 is caused to move to the right in the Figure and simultaneously the front plate 75 is rotated about the axis 76 such that the forks take up the positions shown as 231a, 232a. The carrier plate 77 is then moved to the left so that the forks take up the positions shown as 231b, 232b. If it is desired to handle a load on the right side of Fig. 3 the midframe 70 is rotated through 180 degrees and the carrier plate 77 and front plate 75 are simultaneously rotated therewith, such that the forks which were originally on the bottom edge of the plate 75 are now on the top edge thereof and pivot downwardly by gravity to an inoperative condition parallel to the plane of the plate 75, whereas the pair of forks on the bottom plate edge pivot downwardly to an operative condition. The forks are mounted on the front plate 75 by means of clevis mounting members (226, 227, 228a, 229a) in which fit bosses of the forks, Fig. 1 (not shown). Movement of the carrier plate 77 along the midframe 70 is effected by a pair of hydraulic rams (218, 219) mounted on the midframe, a chain (221) which extends from an anchorage adjacent each of the rams and passes about a chain wheel attached to the piston rod of each ram is anchored at a point in its run to the carrier plate 77, Fig. 1 (not shown). A further pair of rams (81, 82) provide movement of the front plate 75 about the axis 76, Fig. 9 (not shown). Rotation of the midframe 70 relative to the rear frame 1 is effected by a hollow shaft (22) carrying at one end a disc (24) which is secured to the front member (11) of the rotator assembly, the member (11) being attached to the midframe 70, Fig. 4 (not shown). The shaft (22) is mounted on a pin (30) and carries a pinion (27) which is in mesh with two rack sections (21, 21a) formed on two common piston rods extending respectively between ram cylinders (16, 17) and (16a, 17a) which are mounted on the back plate of the rotator assembly, Fig. 5 (not shown), movement of the said two piston rods producing rotation of the shaft 22 and thus the rotation of the midframe 70.

Filed: 1955-03-21
Abstract: 773,706. Cathode-ray tube circuits. HAZELTINE CORPORATION. March 21, 1955 [April 12, 1954, Nov. 26, 1954], No..8162/55. Class 40(7) In a projection colour television receiver in which images produced by a plurality of cathode-ray tubes are combined in register on a viewing screen degradation of focus and of register due to variations in (1) the E.H.T. voltage or (2) in the beam focusing current applied to the tubes is reduced by effecting a compensating variation in (2) or (1) respectively, Fig. 1, shows one embodiment in which compensation for variation in E.H.T. voltage from source 44 is effected by means of a regulator circuit 45 comprising valves 90, 91, the common anode/cathode circuit of which is included in the circuit of the focusing coils 36, 37, 38 and the control grid/cathode voltage determined by the voltage derived from potentiometer 93 connected across source 44. Variations of the voltage from the latter source is then effective to vary the focussing current (from source +B2) in direct proportion thereto and therefore the focusing magnetic field intensity is held proportional to the square root of the E.H.T. voltage which is the required condition for correct operation. In a second embodiment, Fig. 3, in which variations of the focusing current is compensated by varying the E.H.T. voltage the former variations produce a voltage across the cathode resistors 139b of valve 147 which, due to the voltage/current characteristic of an incandescent lamp 139 connected in series with the focusing coils 136, 137, 138, is proportional to the square of such current variations. This voltage is then utilized, by varying the conduction of valves 147, 149 and 144a, to vary the current which the latter valve draws from the E.H.T. supply 144 and thus to vary the voltage of the latter in proportion to the square of the focusing current variation. To prevent large variations in focusing current a ballast tube 131 which provides an increased impedance to increased current flow and vice versa is included in the circuit of the focusing coils. An adjustable focusing coil unit, including an adjustable magnetic shunt, which is suitable for use with the picture tubes in each of the embodiments, is described in connection with Fig. 2 (not shown). Specification 689,356 [Group XL(b)] is referred to.

Abstract: 941,769. Automatic exchange systems; multiplex signalling. SIEMENS & HALSKE A.G. March 7, 1961 [March 8, 1960], No. 8371/61. Headings H4K, H4L and H4R. Both way channels carrying speech in a band f 1  to f 2  are scanned at a frequency which may be different for each channel by gating each channel over modems to band-pass filters which select a sideband product of the speech band with the scanning frequency, each of the sidebands being distinct and particular to a channel so that the band-pass filters may be commoned to a frequency multiplex line. As shown in Fig. 3, the speech band in each of three channels is filtered by TP1, TP2, TP3, and the channels are sampled by the switches T1, T2, T3, which all scan at the same frequency. Band-pass filters BP1, BP2, BP3, each selecting a different modulation product of the scanning frequency, connect the channels in common to a frequency multiplex highway W. At the far end of the highway W the sidebands are separated by filters BP4, BP5, BP6, scanned by switches T4, T5, T6, and demodulated in low-pass filters TP4, TP5, TP6. The arrangement is symmetrical and therefore provides for transmission in both directions. Each combination of two filters and a scanning switch may be as shown in Fig. 1, where the diode or transistor switch T scans at a frequency to which an inductor Lt and capacitors C1 and C2 are tuned. The arrangement is applied as a line concentrator for an automatic satellite exchange as shown in Fig. 4. Subscribers R1 to R12 may be connected to the multiplex highway M1 over switches T1 to T12 in any one of three time positions corresponding to the time positions of scanning switches T13, T14, T15. Each subscriber is connected over a low-pass filter TP and, depending on the time position of his connection, over a bandpass filter BP1, BP2, or BP3, which defines his channel over the frequency multiplex highway W. At the main exchange filters BP4, BP5, BP6, and scanners T16, T17, T18, convert the channels to time divisions on the highway M2. Selective access to the exchange equipment is then to be had over switches such as T19, T20. The switches T16, T17, T18 scan at substantially the same frequency as switches T13, T14, T15; difference between these scanning frequencies producing a frequency shift.
