Patent YU-2090-A (YU)
Inventor: DANGSCHAT R
IPC: H02M3/335
Filed: 1990-01-05
Abstract: The invention relates to a circuit arrangement for a freely oscillating isolating transformer switched-mode power supply having a control device (IC) for the pulse-width-modulated triggering of an electrical switching element (T1). As control information, this control device (IC) receives, inter alia, on an input terminal (8) a zero passage detector signal (Uzero) and, on a further input terminal (1), a control voltage (UR), which is dependent on the output voltage (UA) of the switched-mode power supply. In order to ensure reliable operation of the circuit arrangement, even in the event of low power consumption and especially in the standby mode with only a few watts no-load power, it is proposed to provide, in addition to a capacitive coupling of the two input terminals (1, 8), a detector device (DE) with whose aid an internal reference voltage (Uref) of the control device (IC) can be reduced in the standby mode. By this means, the increase in the output voltage, which is undesired in the standby mode and is increased even further by the capacitive coupling, can effectively be avoided.

Abstract: 686,182. Heating liquids and gases. SPANNER, E. F. and SPANNER BOILERS, Ltd. Dec. 15, 1950 [Jan. 9, 1950], No. 515/50. Classes 64 (i) and 64 (iii) A heat exchanger comprises a water containing pressure vessel fitted with parallel tubes arranged in groups, all the tubes being expanded into a pair of spaced tube plates and each group of tubes having an inlet and an outlet header, heat being transferred by way of the water in the pressure vessel from hot fluid flowing through the tubes of one or more of the groups to cold fluid flowing through the tubes of the other or remaining groups. In the form shown the pressure vessel J contains separate groups B, E of tubes, hot liquid or gas being passed through the tube group B, and water to be heated flowing by natural circulation through the tube group E to a hot water storage tank K, having a hot water draw-off pipe K<SP>1</SP>, a make up tank L being provided. A further vessel M is arranged above the level of the vessel J and is connected to the water space of that vessel surrounding the tube groups. Initially, the vessel J is completely filled with water and the level in the vessel M is at X-X. As the water in the vessel J becomes heated steam is formed and depresses the water level therein to the level Y-Y or Z-Z, the level in the tank M rising correspondingly to Y<SP>1</SP>-Y<SP>1</SP> or Z<SP>1</SP>-Z<SP>1</SP>. As the water level falls in the vessel J the tube surface in contact with the water and therefore heat transferred in the water by the tube group B is reduced, but heat is still transferred to the exposed parts of the tube group E by the steam. Air pressure may be applied on the surface of the water in the vessel M thereby raising the temperature at which steam is formed in the vessel J. Specification 569,000 is referred to.

Filed: 1954-01-11
Abstract: 763,196. Pulse radar. SPERRY RAND CORPORATION. Jan. 11, 1954 [Jan. 12, 1953], No. 583/56. Divided out of 763,195. Class 40(7) In a pulse radar an echo pulse received during one recurrence period is subtracted from the mean of the corresponding echo pulses received during the preceding and succeeding recurrence periods to give a resultant output dependent on the radial velocity of the target. As shown the radar includes a stable R.F. oscillator 9 to provide coherent detection and the video output from receiver 3 is modulated at 6 on to a carrier from oscillator 7 and applied directly to detector 8 and to detectors 12, and 15 through delay lines 10 and 13 respectively which delay the applied signals by t and 2t respectively where t is the pulse recurrence period. The undelayed output from detector 8 is combined in circuit 16 with the " twice-delayed " output from detector 15 and subtracted in circuit 17 from the " once-delayed " output from detector 12 to give the required signal. Fig. 6 (not shown) illustrates the discrimination provided by the system and Figs. 2 and 3 (not shown) which are identical with Figs. 2 and 3 of Specification 763,195 illustrate applications of the invention to a long range radar employing a single delay line which is used to provide moving target indication (M.T.I) during an initial predetermined portion of each pulse recurrence period and which is used during the remainder of each recurrence period to add, i.e. integrate, corresponding echoes received during any two successive recurrence periods. In these embodiments the " twice-delayed signals are obtained by re-circulation through the delay line. If co-herent detection is employed during the M.T.I. period of operation, the reference oscillator is switched off during the integration period.
