Title: Desalination process by multi-effect,multi-stage flash distillation combined with power generation
IPC: C02F1/16
Filed: 1967-04-18
Abstract: Heated sea water is passed from line 22 serially through the flash chambers of a multi-stage flash evaporator which are maintained at successively lower pressures, the vapour flashed off from the sea water in the chambers of the stages 106e, 106f at lowest pressure, preferably in excess of atmospheric pressure, is passed through lines 124, 126 to a low-pressure turbine 38 which is coupled to a generator 40 for producing electric power, and the vapours produced in the other flash stages are condensed directly on the condenser tubes associated with these flash stages. The condensate is. withdrawn from the evaporator to cooler 70. The exhaust steam from turbine 38 is passed to condenser 44, from which the condensate mixes in line 50 with the distillate from cooler 70, thus collecting the desired product, i.e. desalinated water, which is withdrawn from the system. As shown, the evaporator has two sets of flash stages 100, 102, associated with a heater 20 supplied with steam from turbine 128 which is itself supplied with high-pressure steam from nuclear reactor 10. The sea water to be distilled is used as cooling-medium in condenser 44, and is then pumped through either distillate-cooler 70 or a brine-cooler 72. The sea water is then treated with acid and is introduced into deaerator 78 from which carbon dioxide and air are withdrawn by eductor 80, operated by a stream of sea water. The de-aerated sea water is pumped through the condenser tubes 108, 110 of the evaporator, and then flows through heater 20 where the temperature of the water is raised to about 260 -290 F. The heated sea water then enters the first flash stage 104a. A portion of the brine from stage 104f is mixed with the feed sea water in the condenser tube of stage 104d, and the remaining brine is fed to the first flash stage 106a of the second set 102. Part of the brine is pumped from the last flash stage 106f through heat-exchange tubes 120, 122 and then mixed in line 116 with the brine flowing into flash stage 106a. The remainder of the brine from stage 106f is discharged from the system through cooler 72. After treatment in deaerator 78, the feed may be preheated by heat-exchange with waste heat from nuclear reactor 10, or bleed steam from turbine 38.

Title: Improvements in or relating to A Sewing Machine Speed Control Device
IPC: H02P7/295
Filed: 1967-09-11
Abstract: A sewing machine is driven by a series motor M through a notched belt 9 bearing iron cleats 16 at regular intervals to form part of a tachometer generator 10, whose stator comprises soft iron parts 11, 12, a permanent magnet 13, and a winding 14. The amplitude and frequency of the voltage induced in the winding 14 is proportional to the speed of the machine. The motor M is supplied from A.C. lines a, b, through controlled rectifier D2 and diode D1, the rectifier being triggered when the voltage across capacitor C is sufficient to break down a Zener diode D3. The capacitor is shunted by transistor T having the tachometer generator 10 in its base control circuit. If the machine tends to over-speed, the transistor becomes more conductive to discharge the capacitor at a greater rate, so retarding the firing-point of the rectifier D2. This reduces the motor current and restores the speed to a set value. Similarly, the motor current is increased to allow for a drop in speed. In a modification, the cleats 16 are formed as permanent magnets constituted by synthetic resin containing a magnetic powder, the magnetic circuit located in proximity to the belt being constituted of soft iron. The control circuit for the motor may be adapted to respond to frequency variations of the tachometer voltage, the control circuit comprising a pulse counter.

Each chart may carry marks that can be sensed and which represent the constants associated therewith so that when a chart is in use constants appropriate thereto can be entered automatically in the computer. The apparatus provides a practical solution to the problem of reducing the complexity of the computation required to convert radio navigation data to co-ordinate data suitable for plotting without introducing undue distortion of the chart.

Title: Electronic timer
IPC: H03K5/04
Filed: 1969-08-19
Abstract: A time delay circuit comprises a potentiometer 5 connected in series with a switching device, shown as transistor, 1 across a supply, a capacitor connected between the tap on 5 and the input of an amplifier, shown as a Schmitt trigger 10, 14, and a constant current device, shown as transistor 20, connected to the amplifier side of the capacitor. When the switch transistor 1 is rendered conducting the voltage at the input of the trigger is reduced by an amount determined by the setting of the potentiometer and the trigger is switched. The capacitor is charged through the constant current transistor until its voltage is sufficient to restore the trigger. A resistor or diode OR gate 2-4 controls the switching transistor 1 and the latter transistor when off allows potentiometer 5 to supply an "on" bias for transistor 14 of the trigger. Further amplifier transistors may succeed the trigger to provide additional and serene sense outputs. The input switch circuit may include a bi-stable circuit which is set to start timing and reset by the output at the end of the timing period. The delay is controlled by the potentiometer and adjustment of the constant current circuit. A lamp 8 connected to the input switch or the output amplifier indicates operation of the circuit. A meter V is switchable into circuit to indicate the potentiometer and thus the time delay, the switch including a back-contact which switches in a resistor equivalent to the voltmeter. A further contact 32 holds the circuit inoperative while the meter is in circuit. The transistors may be formed in an integrated circuit mounted on a printed circuit load. Resistor 24 and diode 25 provide temperature compensation.

Title: Transistorized vertical deflection circuit
IPC: H03K4/71
Filed: 1972-10-31
Abstract: Transistorized vertical deflection circuit employs output stage of class B, push-pull, complementary symmetry configuration. Miller integration approach is used for sawtooth wave generation, with feedback waveform derived from yoke current sampling resistor. Diode, coupled between ground and base of the (NPN) output transistor which conducts during retrace and first half of scan, operates in Zener region during retrace to hold voltage at joined emitters of output pair at s substantially constant voltage during retrace output waveform is thereby stabilized against effects of B+ changes due to line voltage variations or loading extremes, and remaining (PNP) output transistor dissipation is held substantially constant in the face of such changes. Diode in feedback path, forward biased when retrace ends, ensures rapid turn-on of driver stage when discharge transistor cuts off oppositely poled diode in shunt with first feedback diode completes low impedance capacitor discharge path during retrace. One winding half of vertical deflection yoke is shunted by a capacitor of a value selected to introduce cancellation of horizontal frequency components across yoke/pincushion circuitry, in order to minimize feedback of interlace-disturbing horizontal components in deflection circuit.

Patent ES-416011-A1 (ES)
Title: Conductively connected charge coupled devices
IPC: H01L29/768
Filed: 1973-06-08
Abstract: There is disclosed improved charge coupled devices having, under the gaps between electrodes, heavily doped zones of a conductivity type such that the majority carriers in the zones are of the same polarity as the mobile charge carriers used for representing signal information. In a described embodiment, lightly doped zones of semiconductivity type opposite that of the heavily doped zones are disposed under the trailing edge of each electrode and intersecting the heavily doped zones. The heavily doped zones facilitate charge transfer across the gaps between electrodes and the lightly doped zones provide potential wells of requisite asymmetry for two-phase operation. Advantages include reduced sensitivity to spurious surface charge, due to the heavily doped zones, and simpler fabrication and potentially smaller bit length, due to the intersecting of the heavily doped and the lightly doped zones.

Title: Air temperature control system for a room having an outside wall
IPC: F24F7/04
Filed: 1976-07-22
Abstract: Present in the device is a framework which is flowed through by a heat transport fluid, consists of hollow uprights (1 - 3) and hollow crosspieces (4, 7) and on which the facade elements are suspended virtually without heat or cold bridges. A convector pipe (11), which is provided in an air supply duct (15) with a lateral air-outlet slot (16), can be connected into the heat-transport fluid circuit thermostatically. According to the mode of operation of the device, the framework consisting of hollow uprights and hollow crosspieces and the convector pipe is supplied with hot or cold water, by which air circulating in the space formed by the framework and in said air supply duct is heated or cooled. The hollow-upright and hollow-crosspiece framework acts in this case as a slowly responding base-load system, while the convector pipe works as a rapidly responding regulating system. As a result of the low volume of the pipes with a relatively large surface, a rapid heating or cooling of the air is achieved with a high efficiency.

Patent ES-456106-A1 (ES)
Title: Hydrostatic transmission control
IPC: F16H59/18
Filed: 1977-02-19
Abstract: A hydrostatic transmission comprising a closed loop system incorporating a hydraulic pump and a hydraulic motor driven by the pump has an accelerator for the motor drive shaft which sets the maximum delivery pressure of the pump, and control means which acts to vary the relative volume displacement of the pump and the motor to maintain the pump delivery pressure at the maximum value determined by the setting of the accelerator. Thus, the closed loop system maintains a substantially constant maximum pressure throughout the flow range, and since the output torque of the motor drive shaft is proportional to this system pressure a true acceleration control is achieved. The relative value displacement of the pump and the motor may be influenced by the low pressure of delivery of the pump on overrun of the motor shaft and by a spring loaded braking valve adjustable by a pedal control to provide for braking of the motor drive shaft.
