Title: Improvements in or relating to methods for the calibration processing of an electrical element
IPC: H01C7/04
Filed: 1950-08-29
Abstract: 677,206. Temperature-variable resistances; condensers; bridge circuits. GARRETT CORPORATION. Aug. 29, 1950 [Sept. 10, 1949], No. 21318/50. Class 37. An electrical element having a critical upper temperature is calibrated by processing while the element is connected in a comparison circuit having an indicating means arranged to give a first predetermined indication when the element reaches its critical upper temperature during the processing and to give a second predetermined indication when the calibration process is completed. The processing method comprises changing the mass of the element in such a manner that the first predetermined indication is not exceeded and continuing to change the mass until the second predetermined indication is shown. The method is described as applied to adjusting a thermistor to a predetermined resistance value, but is also applicable for adjusting capacitors. A thermistor 10, Fig. 1, comprises a glass probe 11 within which are embedded a pair of conductors 12, the ends of which are embedded in a bead 13 of metallic oxide semi-conductor. A thin glass envelope 14 encloses the bead 13. The thermistor 10 and a reference thermistor 23, Fig. 3, are arranged in two arms of a Wheatstone bridge, the other two arms of which are formed by resistors 21, 22. The reference thermistor 23 is maintained at a constant temperature by immersion in a bath 24 of mercury, oil, &c. In series with the galvanometer 27 is variable resistor 28 which is shunted by a normally-open switch 29. The resistance of the thermistor is changed by grinding the end on a grinding-wheel 31 driven by a motor 32, or by removing portions of the bead 13 by drilling. With switches 26, 30 closed the resistor 28 is adjusted so that the galvanometer 27 gives a full-scale reading. The thermistor 10 is replaced by a resistor having a resistance equal to that of a standard calibrated thermistor at 300 F., and the reading of the galvanometer is noted with switches 29, 30 open, the resistor then being replaced by the thermistor 10. Grinding is then proceeded with, the galvanometer being observed during the operation. Whenever the temperature of the resistor reaches 300 F. the galvanometer gives the previously-noted reading, and the grinding is stopped to allow the thermistor to cool. The progress is checked by dipping the thermistor 10 into the bath 24 and noting the galvanometer reading. The galvanometer 27 may be calibrated to read percentage difference of resistance between the thermistors 10, 23. When the resistance of the thermistor 10 has reached its desired value it may be given a protective coating 40, Fig. 2, of varnish &c.

Title: A method of utilizing the natural heat of the earth to generate electrical power
IPC: F03G7/04
Filed: 1944-11-01
Abstract: 588,375. Utilising solar and natural heat. OKOLICSANYI, F., and BANSZKY, L: Nov. 1, 1944, No. 21327. [Class 64 (ii)] A means for utilizing the natural heat of the earth to generate electrical power comprises two chambers 1 and 3, chamber 1 being at a depth sufficient to ensure that the temperature there is independent of seasonal variations, the two chambers being connected by a borehole 2, in which are pipes 4 and 8 of a fluid circulating system. In the example, water passes through the spiral 5 in chamber 3, being there warmed by the heat of the earth, and ascends by the pipe 4 to the thermally-insulated storage tank 6, from which it is drawn to heat the junctions of the thermopile adjacent the tube 7, the cold junctions of which are maintained at a low temperature by cold water flowing through the outer jacket 9. The electrical output is taken from the terminals 13 and 14. A second cellar above cellar 1 may be used in cold weather. The Provisional Specification states that instead of a thermopile other devices for converting heat into electricity may be used and if a thermopile is employed, it may be as described in Specification 588,369, [Group XXXVI].

Title: Improvements in or relating to pneumatic gauging apparatus
IPC: G01B13/22
Filed: 1948-08-13
Abstract: 654,782. Fluid-pressure gauging apparatus. SHEFFIELD CORPORATION. Aug. 13, 1948, No. 21399. Convention date, Oct. 24, 1947. [Class 106 (ii)] A pneumatic gauge for measuring surface roughness comprises a member 52, Fig. 3, having an air outlet orifice surrounded by an annular ring 50 of yielding material to which is fixed a flexible disc 51 perforated to permit the passage of air and having a smooth gauging surface which is applied to the surface to be gauged. The flexible nature of the disc 51 permitting it to conform to major waves or irregularities in the surface to be gauged, the flow of air being controlled by the small gaps between the smooth gauging surface of the disc and the minor irregularities of the surface to be gauged. The member 52 is supported in a member 54 with a handle 62 in such a manner that it is free to accommodate small angular discrepancies relative to the surface to be gauged, as shown in Fig. 4, and is applied to the surface with constant pressure exerted by the spring 57. A spring-loaded protective skirt 58 is also provided. In order to magnify the small changes in flow of air through the tube 13 indicated by the float 14, consequent upon change in the surface roughness, the unit 17, Fig. 2, is interposed between the flow-tube 13 and the gauging head 54. Air flow enters from the tube 13 into the unit 17 via a gland nut 15 and into a passage 23, thence via passage 24 past valves 35, 36, to passage 26 and through pressure chamber 27 to the bore 31<SP>1</SP> of the member 18 and on to the gauging head. In the pressure chamber 27 a piston 29 having the shape shown in Fig. 2, and a spring-loaded valve 39, are located. With the valves 35 and 36 open the pressure on either side of the piston 29 is the same and it remains in the position shown; there being sufficient clearance provided for the passage of air to the bore 31<SP>1</SP> by cross-cutting the member 30 at 33, as shown. When valve 35 is closed and air cannot pass through passage 25, the pressure on either side of the piston 29 becomes unequal and the piston rises, carrying with it the valve 39 which opens a passage, not shown, from passage 23 to the outside air, thus increasing the flow of air through the tube 13. Small fluctuations of air flow past the gauging head cause corresponding movement of the piston 29 to increase or decrease the extra air-flow through the flow-tube 13, thus magnifying the changes. Adjustment of the valve 36 varies the total flow through the flow tube and positions the float 14 in mid-scale position for various degrees of surface roughness. Specification 548,568 is referred to.

Abstract: 1,122,886. Fuel injection pumps. ROBERT BOSCH G.m.b.H. May 9, 1967 [May 9, 1966], No.21471/67. Heading F1A. In a fuel injection pump of the type in which a spill valve is actuated by liquid delivered by an auxiliary pump, the cam drive of the auxiliary pump pistons is ineffective at start-up speeds. In the embodiment shown in Fig. 1 a rotary pump head 4 has an injection pump cylinder 8 and an auxiliary pump cylinder 9 and is combined with a rotary valve and distributer 3. The cylinder 8 is connected to a bore 18 terminating in a groove 19 connected with inlet grooves 20 and an outlet groove 22; the bore 18 also connects with a groove 42 in communication with a passage 33 leading to the cylinder of the spill valve 15. A groove 28 connects by passages 29 with the cylinder 9 and by passages 39 and throttle passage 40 with the actuating chamber 32 of the spill valve 15. The groove 28 and hence the cylinder 9 is connected on the suction stroke of the auxiliary pump to an inlet 26 and through a valve 31 to the chamber 32, by the grooves 27. The inlet chamber 7 is fed by feed pump 45 with liquid at a pressure variable with speed. Fuel passes through a pressure maintenance valve 52 to a chamber 55 to lubricate the cam mechanism and passes from the chamber 55 through a pressure maintenance valve 56. One of the auxiliary pump pistons 16 has a spring 58 therein which engages the tappet 11 so that without pressure in the inlet chamber 7 and cylinder 9 the pistons 16, 16a engage and reciprocate together so that no pressure is generated to operate the valve 15 is that maximum fuel is delivered. When pressure builds up in the chamber 7 and cylinder 9 the pistons 16, 16a are pushed into engagement with their cam followers and liquid is delivered to the chamber 32 of the valve 15 to regulate the spill. In a modification, Fig. 4, the auxiliary pump chamber 25a is formed in one of the injection pump pistons 10a and the auxiliary pump piston 16b is disposed in coaxial bores in the pistons 10a, 10b, a spring 58a being disposed between the pistons 10b and 16b. In addition to the spring loading the auxiliary pistons 16, 16b are subjected to the pressure in the chamber 55 which pressure may be varied by setting the valves 52, 56, so that the point of delivery by the auxiliary pump may be varied.
