Abstract: 1,246,395. Cooling I.C. engines; axial-flow fans. CATERPILLAR TRACTOR CO. Sept.22, 1969, No. 46620/69. Headings F1B and F1C. [Also in Division F2] In an engine cooling system wherein a cooling fan 33 is driven by an engine 11 through a hydraulic coupling 55 supplied with oil from the engine under the control of a thermostatic valve 41 responsive to engine coolant temperature, a centrifugally operated valve 65 fast with the turbine drains the coupling when the fan reaches a predetermined speed. Below a predetermined coolant temperature the valve 41 allows a minimum flow through the coupling 55 to cool the latter. An orifice 57 permitting oil to drain from the coupling 55 and return to the engine through a line 59. Above the predetermined temperature the valve 41 is opened to permit an increased flow of oil to the coupling 55 which is filled to provide a drive to the fan 33. When the fan speed reaches the predetermined value the valve 65 opens against the bias of a spring to drain the coupling 55 and thus limit the speed of the fan.

Title: Voltage memory circuit

Abstract: 1,034,980. Automatic voltage control. B. H.VINSON. Nov.24, 1964 [Dec. 9, 1963], No. 47782/64. Heading G3R. A circuit for the storage of a voltage, e.g. an analogue signal, over a relatively long period of time comprises a capacitor to which the voltage to be stored is applied at a given instant in time and a charging circuit which periodically adds an increment of voltage to the stored voltage when the value of the latter, because of leakage, falls by a predetermined amount. In the preferred embodiments (Figs. 1 to 4, not shown), the stored voltage E1 and a ramp voltage E2 are applied to a comparator which provides a comparator pulse whenever E2 exceeds E1. Pulse generating means responsive to the comparator pulse provides an actuating pulse for a recharge circuit connected to the storage capacitor, there being a gate connected between the pulse generating means and the recharge circuit; the gate is continuously opened and closed by timing pulses so that the gate is closed at given times to the actuating pulse. However, when the stored voltage decreases slightly, the point in time at which the ramp voltage exceeds the stored voltage is shifted so that the resulting comparator pulse, and thus the actuating pulse, is shifted in time to a position at which the gate is open whereby the recharge circuit is actuated to replenish the stored voltage by the addition of a given increment of voltage. The stored voltage is thus automatically maintained at a desired given value.

Title: D.c. clamping circuits

Abstract: 1,274,093. D.C. clamping circuit. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 30 Sept., 1969 [2 Oct., 1968], No. 47997/69. Heading H4F. In a D.C. clamping circuit in which the output of a D.C. coupled amplifier 3 is connected through the series combination of a diode 12 and a capacitor 10 to a pulse voltage source 9, the junction A of the diode 12 and capacitor 10 is coupled through a diode 13 (instead of a resistor) to a direct-voltage input 17 of the amplifier shunted by a smoothing capacitor 14. The television signal to be restored is applied to input 1 and the circuit output is taken from terminal 8. In operation capacitor 10 is charged during the sampling periods (pulses from source 9) to the voltage difference between the pulse peak and the reference level at the collector of transistor 4. Outside these sampling periods diode 12 is cut off and at junction A appears a negative going voltage which opens diode 13 and is transmitted to capacitor 14. The resulting control-voltage is applied to the direct-voltage input of amplifier 3 for adjusting its working point. When the reference level at the collector of transistor 4 becomes more negative (less positive), the voltage at junction A becomes more negative outside the sampling periods and hence the collector current decreases and its voltage becomes more positive. Since the controlvoltage for amplifier 3 should have an absolute value, a positive current is supplied to capacitor 14 from the supply source via a large resistor 15. When the reference level at the collector of transistor 4 becomes more positive, the voltage at junction A becomes positive outside the sampling periods and diode 13 is no longer opened with respect to the more negative voltage of capacitor 14. Resistor 15 is then traversed by a more positive current which is supplied to capacitor 14 until diode 13 is again opened. A series combination of a plurality of diodes may be employed instead of the diodes 12 and 13.

Abstract: 1370070 Concentrating boric acid solution WESTINGHOUSE ELECTRIC CORP 23 Oct 1972 [30 Nov 1971] 48678/72 Heading BIB A moderating solution for a nuclear reactor, e.g. an aqueous solution of boric acid, is concentrated by feeding the solution through a preheater 1 and a gas stripping column 5 into evaporator 11 from which part of the vapour is returned to the column 5 and part led to condenser 25; gas and vapour from the column 5 pass to vent condenser 43, condensed vapour being returned to column 5 and gas being discharged at 53. The process alternates between a distillation stage in which there is continuous feed of weak boric acid solution and continuous discharge of pure water and, when the boric acid solution has reached a desired concentration, a recycling stage wherein the feed is shut off, water is recycled, and concentrated boric acid is removed. When changing from recycling to distillation, the feed valve is opened, while maintaining valves 75, 91 closed and valve 77 open; after a first interval, valve 77 is closed, valve 75 opened, and heat applied to preheater 1, and after a second interval, valve 91 is opened. Controllers 63, 67, 73, 79, 81 regulate the process according to the level of liqiud in evaporator 11, the temperature of the feed, the pressure in evaporator 11, the amount of liquid in condenesr 25, and the purity of the distillate. The solution treated may be a portion of the coolant moderator in a pressurised water reactor. Pure water and a 12% boric acid solution are obtained and may be fed in varying amounts to the coolant in order to control the power output of the reactor.

Abstract: 1372244 Load handling MULLARD Ltd 2 Nov 1971 50797/71 Heading B8H [Also in Divisions H1 H2 and H3] A magnetic holding device 1, e.g. for lifting loads comprises strontium ferrite permanent magnets 2 interposed between mild steel plate poles 3, 4, 5, 6; a control winding 7 surrounding the upper parts of poles 4, 5 and stainless steel members with stops 9 being secured to poles 3, 6 to limit movement of a mild steel keeper to and from the pole faces. The keeper has a central lifting eye 11, and non-magnetic headed spacer rods 12 extend from the upper face of the keeper for a distance equal to the length of the poles 3, 4, 5, 6, + a maximum operating airgap, and are a sliding fit in bores of poles 3, 6. A non-magnetic control rod 14 with stop 15 at upper end slides in bore 16 of pole 4, and operates a monopole microswitch S1 and bipole changeover switch S2 (not shown) mounted on top of keeper 10, so that S2 operates before S1; whenever load 17 and keeper 10 are at a critical separation exceeding the length of spacers 12. On lowering the device to a floor to lift or release a load, capacitor C (Fig. 2) previously charged from battery 19 is switched to discharge into base of transistor 20 which conducts batteries 18, 19 to pulse winding 7, so that the magnet switches from a first to a second condition in which the attraction between poles and load is increased and that between poles and keeper is decreased. The keeper plate 10 is released and lifted by spacing rods 12 abutting the load, and after the energizing pulse the magnet flux threads and retains load 17. On lifting, S 1  recharges the capacitor and S 2  remains closed; the keeper bearing on stops 9. On again lowering, the keeper plate 10 is released towards the upper poles, S 2  reverses the connections to winding 7, and S 1  discharges C to reverse the magnetic circuit condition, so that the pole-keeper attraction exceeds the pole-load attraction, and the spacer rods slidably displace the load so that the holding device may be lifted clear (Figs. 3-7, not shown). A graph (Fig. 8, not shown) gives the relationships between load and non-magnetic gap between poles and load, and constructional constants are quoted.
