Title: Improvements in Gas-Fired Circulatory Water-Heaters
IPC: F24H9/20
Filed: 1966-09-22
Abstract: 1,150,900. Water heaters. JUNKERS & CO. G.m.b.H. 22 Sept., 1966 [30 Sept., 1965], No. 42269/66. Heading F4A. A gas fired circulatory water heater comprises a coiled pipe 11 and an upper lamellar heat exchange block 14 surrounding a combustion chamber into which burner 21 fires. The heater is connected to a central heating circuit including radiators 19 and circulating pump 20. The gas supply to the burner 21 is through a thermo-electrical ignition safety valve 23 and a water deficiency safety valve 241. Additionally, a sensor 25 of a liquid filled thermostat is mounted on the outlet pipe 16 of the heater at a distance between 20 and 100 millimetres, preferably 50 millimetres, from the outlet 15 of the lamellar block 14. This is effective to turn off the gas supply by means of valve 23 if the water temperature in the outlet pipe 16 exceeds the predetermined value, e.g. 90 or 110 C. in normal or pressurized operation, respectively, or in the event of the lamellar block 14 overheating under abnormal conditions, due to deficiency of water flow and the valve 241 failing to operate, but to be unaffected by the normal rise in water temperature due to residual heat on shut down of the heater. The sensor 25 is detachably mounted in a groove on a plate 27 hard soldered to the outlet pipe 16 and maintained in place by a cover-plate (not shown) secured to the plate 27 by a screw 30. Alternatively the sensor may be secured in a tubular sleeve attached to the outflow pipe.

Abstract: 1,132,093. Drafting apparatus; stop motions. MAREMONT CORP. 6 Oct., 1965 [7 Oct., 1964], No. 42454/65. Headings DID and DIN. Drafting-mechanism comprises at least two pairs of rollers and a control bar positioned against the material being drafted between the pairs of rollers, whereby the strand is deflected partially around the periphery of one of the first pair of rollers taken in the direction in which the strand is moving, means for adjusting the control bar to adjust the size and position of the gap between it and said one roller, the control bar having a convex surface adjacent said one roll merging into a concave surface facing the nip between the said first rollers. In Fig. 3, three pairs of rollers 24, 22, 30, 28 and 34, 32 are provided the strand, moving from right to left, and 30, 28 being the first pair referred to above. The plane through the rotational axes and the nip of the rollers 30, 28 lies forwardly of the plane at right angles to the drafting field so that the strand on leaving the nip is deflected for a distance along the surface of the upper roll. A bar 54 which is adjustable at 56, further deflects the strand; it has a profiled surface 58 facing the nip of the rollers 30, 28 and a rounded snubbing surface 60. Associated with the pair 24, 22 is an additional upper roller 26 which can be removed for longstaple fibres. Each upper roller is mounted in blocks e.g. 40, Fig. 5, slidable in a slot 38 in a member 36, which is fixed, except in the case of the rear top roller 34 where the blocks are adjustable along bars 48. The rollers are preferably fluted and magnetically-loaded. Each block 40 has a lateral extension 74, with an adjustable set-screw 76 normally bearing on the plunger of a switch 70. When a lap occurs on the associated roller, the roller is raised to release the plunger and actuate a stop-motion. The drafting rollers are driven by the front lower roll 22 which is geared to the other bottom rolls and is provided with an auxiliary drive as described in Specification 1,132,094. Beyond the drafting apparatus, Fig. 2, are fluted calender rollers as described in Specification 1,132,095 comprising one, 92 meshing with two others 94, 96 disposed as shown to deflect the strand path through a right angle. For conducting the strand from the drafting rollers to a trumpet 138 in front of the calender rollers, there is a gathering-plate 134 extending along the length of the rollers and conical and tubular parts 134, 136. The guide is pivotally mounted and a stop motion may be actuated on movement of the pivot 131.

Abstract: 899,024. Measuring bridges. LONDON ELECTRICAL MANUFACTURING CO. Ltd. Dec. 16, 1960, No. 43340/60. Class 37. A capacitance test bridge (Fig. 1) comprising #Z1 Z2 arms Z1, Z2, Z3, Z4 balanced when - and -, #Z3 #Z4 having a test and a standard capacitance in arms Z1, Z3 or Z2, Z4 and equal resistances in the remaining arms is energized across one diagonal by an asymmetrical pulse waveform of mean level 11 (Fig. 2) and the unbalance output signal is applied to an amplifier 14, limiter 15 and D.C. removing capacitor 16 to an indicating device which may be a gas discharge tube. The unbalance output is zero for equality of the capacitances and consists of positive-going pulses (Fig. 3) for one sense of deviation and of negative pulses (Fig. 4) for the other sense of deviation, so that with appropriate bias the gas tube may fire to indicate the presence of a capacitance exceeding standard by a predetermined amount while remaining inoperative for capacitances equal to or below standard. A further bridge may be correspondingly arranged to indicate capacitances below standard by a predetermined amount. Electromechanical rejection devices for non-standard capacitances may be operated by the gas tube, and the energization may consist of any asymmetrical waveform, e.g. a sawtooth. The bridge may also test other impedances for tolerance.

Abstract: 1,029,296. Liquid fuel burners. FALLS STAMPING & WELDING CO. Nov. 23, 1962 [Nov. 24, 1961; Nov. 9, 1962], No. 44498/62. Heading F4T. In a system comprising a plurality of burners heating a furnace, a water heater or an incinerator, the fuel oil is maintained at levels just lower than the nozzles of the burners by valves in oil containers C, Fig. 1 (not shown), and air supplied to the burners aspirates the oil from the nozzles. The oil is delivered to the containers C from a supply tank by a pump and surplus oil is returned from the containers C to the supply tank. If the burner nozzles are all at the same level a single container C suffices. The air is supplied by a compressor disposed within the housing of the oil pump and connected to a manifold from which pipes run to the burners. A regulating valve R is located between the compressor and the manifold and a spring-loaded valve is located in a return pipe connecting the manifold to the inlet of the compressor. A solenoid valve S in each air pipe to the burners is operated by a flame sensor FS at the burner. The air supplies are further controlled by a furnace thermostat, an aquastat in the hot water heater and a timer in the incinerator so that the burners thereof are individually controlled. Each burner, Fig. 2, comprises a nozzle 5 supplied with oil by a pipe 7 and with air by a pipe 6 and discharging an oil/air mixture through a central hole in a metal screen 26 into a perforated cylindrical flame guide 12 enclosed in a combustion chamber 17. Spark ignition electrodes 8 are mounted in a recess 19 in a porcelain ring 9 and the spark is blown into the mixture by a current of air passing through an inlet 23 in the ring. A cap 10 is mounted on the porcelain ring 9 and air is delivered to the space within the cap by a conduit 11. Part of this air passes through openings 13, 14 into the flame guide 12 and part through openings 16 in the porcelain ring 9 into the combustion chamber. The burning mixture circulates through the forward apertures in the flame guide into the annular space between the combustion chamber 17 and the flame guide and returns through the rear apertures of the flame guide. The mixture is partially burned in the flame guide and passes through a Venturi 27 to a second burner comprising a flame deflector 29 and screens 28<SP>1</SP>, 30 defining a chamber 28.
