Patent DK-95590-A (DK)
Inventor: THORVALDSEN TERJE
IPC: H04B1/707
Filed: 1990-04-18
Abstract: The invention concerns a method for incoherent demodulation of orthogonal-coded DSSS signals modulated by MSK or similar types of modulation. The data signals are retrieved by dividing the receiving signal into two parts, where the carrier wave is converted down to the basic band of a signal S12, S22 which is not matched to the phase of the carrier wave, after which the converted-down signals go through a correlator 13, 14, quadrature devices 15, 16 and addition devices 17, 18 and finally a discriminator 19 which always selects the highest correlation peak as the output signal S30. <IMAGE>

Title: Improvements in or relating to combustion apparatus
Inventor: WIGG LESLIE DESMOND
IPC: F23R3/34
Filed: 1952-01-02
Abstract: 723,010. Generating combustion products under pressure. POWER JETS (RESEARCH & DEVELOPMENT), Ltd. Dec. 30, 1952, [Jan. 2, 1952.] No. 196/52. Class 51 (1). A combustion chamber having an air inlet in the region of which large drops of fuel are introduced, a flame stabilizer and ignitor spaced downstream from the inlet and an atomizing liquid fuel injector which injects fuel into the chamber on the downstream side of the flame stabilizer, is formed with a diffusing duct through which the air stream flows from the inlet to the flame stabilizer. The annular combustion chamber shown comprises an air casing formed by two tubular walls 11, 12 enclosing an annular flame tube formed by two co-axial tubular walls 13, 14. The flame tube and the air casing each comprise an upstream diffuser passage followed by a parallel section. The divergence of the portions 11b, 11c, 12b, 12c of the air casing is greater than the divergence of the corresponding sections 13b, 13c, 14b, 14c of the flame tube so that there is a small amount of diffusion in the passage between the walls. To maintain an equal distribution of air around the flame tube, the radial spacing of the inner walls of the casing and flame tube is greater than that of the outer walls. The apertures 20 are longer than the apertures 19 to compensate for their reduced width arising from the smaller circumference of the inner wall. A fuel manifold 27 is mounted between cylindrical walls 13a, 14a of the flame tube. Fuel is supplied in this manifold at a small excess pressure so that the fuel enters the air stream in the form of comparatively large drops which are atomized by the velocity of the airstream. The fuel is ignited by a plug 35 mounted on the downstream side of a flame stabilizer baffle 30. The baffle 30 consists of an annular channel facing downstream with a large number of fingers 31a, 31b which extend to the walls of the flame tube where they are joined together 32a, 32b. A number of fuel injectors 33 of the atomizing type are located within the gutter. These injectors form pilot flames which are used for igniting the chamber under starting and idling conditions, but are used continuously. In another embodiment the flame stabilizer 30 is formed as a gutter of triangular cross section with the outside rearward edges turned in so that the width of the open end is less than the maximum width of the gutter. The atomizing fuel injectors in this case face upstream. The flame tube is supported from the outer casing by a ring of channel-shaped brackets 15, 16 and by strips of metal 17, 18. Reference has been directed by the Comptroller to Specification 690,941.

Abstract: 155,998. Superior Manufacturing Co., Woock, W. R., and Woock, H. J. Jan. 5, 1920. Multi-stage screw pumps; w o r m pumps; casings.- In a pump of the type in which pump units are installed in a well casing at spaced intervals, the rotary parts of each pump unit are carried by a sleeve which is removably mounted on the main shaft, and are supported in the casing so that the weight of the rotary parts is taken off the shaft. The spiral runner 14 is keyed to a sleeve 7 provided with spline-ways 8 which receive the lower splined end 9 of the shaft 10. Integral with the runner 14 is a casing 15 having a projecting part 16 with a running fit on the lower end 17 of a casing 1 and provided with a flange 18 supported by a ball bearing 19 mounted in a casing 20 screwed at 21 to the casing 1. Screwed to the lower part of the casing 20 is a pipe 24 screwed at 24<a> for connection with a plain pipe. A spline shaft 29 carried by the pipe 24 fits into spline-ways 28 carried by the lower end of the sleeve 7 and extends downwards to a similar pump unit below. The shafts 10, 29 are enclosed in tubes 30. Above the pump the casing 1 is provided with vanes 3 which radiate from, and are integral with, a hub 4, and which are directed in a direction opposite to that of the spirals of the runner, so that the water thrown up by the pump will be diverted upwardly through the compartments formed by the vanes. To lubricate the pump units, oil placed between the tube 30 and the shaft 10 passes by apertures 31, 32 to the interior of the sleeve 7, from which some oil passes down to the shaft 29 by a groove 33. Oil is also forced through an orifice 34 into a pipe 35 in the runner 14 and is emptied into a pocket 36 in the casing 20 which has a vertical orifice communicating with an oil reservoir 22. Oil from this reservoir is conveyed to an opening 38 for the ball race 19 by a spiral conveyer 39 having a cone 40 at the top seated on a bevel face 41 on the flange 18 and is rotated thereby. In a modification, the runner 14 is separate from, and bears directly against, the casing 15.

Filed: 1956-01-09
Abstract: 818,946. Cartons. BERGSTEIN, R. M., and BERGSTEIN, F. D. Jan. 9, 1956, No. 743/56. Class 18. In order to produce a liquid tight upper end closure, a carton has two or more outwardly turned narrow flaps to which one or more end closing flaps are sealed, sealing pressure being applied by members on the exterior of the carton. In one form, the closure comprises flaps 12, 13 to which flaps 6, 10 are sealed, these panels, having a pouring opening 11 and liftable portion 7. The portion 7 has extensions 8, 9 for crimping over the protruding seam edges. In other embodiments, Figs. 34-42 (not shown), a closure flap may be sealed to three narrow flaps, or two closure flaps on opposite walls may be sealed to narrow flaps on the remaining walls. No pouring opening is provided in these embodiments. The bottom closure in all cases may be conventional and both closures may be coated internally with a layer of sealing compound applied in liquid form. In one method of forming cartons having pouring openings, the bottom closure is completed on mandrels 19, Fig. 5, on a chain conveyer 20 and the carton inverted into holders 22 on a further conveyer. It is tilted with its side seam directed downwardly and sealing compound is injected from a nozzle 23. The carton is re-erected so that the compound forms a layer 25 over the bottom closure and leaves a sealing strip 26 along the side seam. The flaps 6, 10, 12, 13 are folded outwardly and adhesive applied by conventional means. The flaps 12, 13 are supported by members 31, 32, Fig. 9, and the flaps 6, 10 pressed onto them. The carton is then inverted and tilted and the portion 7 raised. Sealing compound is injected through the opening 11, the portion 7 is closed and the carton held upright in its inverted position so that the compound sets as a layer on the upper closure. When the portion 7 is again raised, a plug 37, Fig. 17, of the sealing layer adheres to it. Pressure may be applied to this plug to make it a tighter fit when replaced. The sealing compound may be applied to the top and bottom closures by various methods, one of which involves providing a temporary opening in the bottom closure, Figs. 26-32 (not shown).

Title: Improvements in or relating to electric transformers

Filed: 1930-01-08
Abstract: 335,858. Associated Electrical Industries, Ltd., (Assignees of Field, R. M.). Jan. 10, 1929, [Convention date]. Systems depending on static transformers.-In an arrangement for changing the tap connections of a power transformer 11 under load, an auxiliary transformer 32 energized from a low voltage source 34, 35 is employed, the auxiliary transformer having a pair of secondary windings 29, 31 adapted to be connected between the tapping switches 21 - - 24 and the power circuit conductor 17 through transfer switches 18, 19, the arrangement being such that tap changing may be effected without interrupting current at high voltage. Minimum voltage between conductors 16, 17 is obtained by closing switches 21, 18, 25, 26. Under these conditions, the potential of the conductor 17 is equal to that of tap 21, less half the voltage between adjacent taps due to negative boost supplied by winding 29. Voltage is raised by an amount equal to half that between adjacent taps by opening switches 25, 26 thus de-energizing windings 29. A further increase in voltage by the same amount is obtained by closing switches 27, 28 thus reversely-energizing the winding 33 and applying positive boost through the winding 29. Before making further increases in voltage, transfer switch 19 is closed bringing into circuit the winding 31 connected to the next tap. Since, however, the voltage of the winding 31 is equal and opposite to that of the winding 29, no change in voltage takes place at this stage. Winding 29 is then cut out by opening switch 18, again without voltage change. A further increase in voltage by an amount equal to half that between adjacent taps may then be made by opening switch 19 thus removing negative boost due to winding 31 and bringing conductor 17 to the potential of the second tap. Further increases in voltages are obtained by similar use of the auxiliary transformer 32.
