Title: Improvements in or relating to heat exchange systems
IPC: B64D13/08
Filed: 1944-01-27
Abstract: 574,469. Heating and cooling air. STEADMAN, C. S., and IMPERIAL CHEMICAL INDUSTRIES, Ltd. Jan. 27, 1944, No. 1545. [Class 64 (iii)] [Also in Group XXIX] In a heat-exchange system for attemperating air supplied to the cabins of aircraft and other vehicles, a stream of air is delivered under pressure to one side of a heat-exchanger and a stream of heating or cooling gases is delivered to the other side, and automatic controlling means maintain the pressure of the air being heated or cooled in the exchanger above the pressure of the heating or cooling gases entering it, irrespective of variations in the absolute pressure of the ventilating air and/or of the heating or cooling gases. Air is supplied by a fan 1 to a heat-exchanger 2, with an outlet duct 4 leading to the aircraft cabin, and hot exhaust gases and cooling air are reapplied through passages 5, 6 to the other side of the heat-exchanger. A cylinder 16 containing a spring-pressed piston 18 is connected on one side of the piston by a pipe 21 to the outlet 4 for the heated or cooled air from the heatexchanger, and on the other side of the piston by the pipe 20 to the inlet 7 for hot gases and cooling air. If the pressure in the outlet 4 falls below that necessary to balance the pressure of the spring and that of the hot gases and cooling air, the piston will move to close the damper 13, which has a stop 14. Dampers 8, 11 operated by a thermostat 9 in the cabin, respectively control the quantities of exhaust gases and cooling air supplied to the heatexchanger, and the quantities of exhaust gases passing to the bypass 10. As the flow of hot gases to the exchanger increases, that to the bypass decreases. The exhaust gases may be forced or drawn through the heat-exchanger by a fan or the like which develops a lower pressure than the air compressor. The fan may be governed directly or indirectly by the air compressor, e.g. by a mechanical governor or by a solenoid energised by a generator driven in unison with the air compressor. Means for filtering the air, adjusting its relative humidity, and re-circulating a part of it, may be provided.

Abstract: 550,632. Partly magnetic switches. BRITISH THOMSON-HOUSTON CO., Ltd. Feb. 6, 1942, No. 1572. Convention date, Feb. 7, 1941. [Class 38 (v)] [Also in Group VI] A coffee infuser comprises a water-heating vessel 10 communicating by a tube 13 with an upper infusing vessel, and heated by an electric element 18 the circuit of which is controlled by a magnet 23 held up against the bottom of vessel 10 by an armature 30 on a pin 33 slidably mounted in tube 13. When the water is boiled, the uprush of steam and water through 13 lifts a disc 31 on the pin 33 and raises armature 30, so that magnet 23 falls by gravity and opens the switch 29 of the heating circuit. When the armature desends, the magnet is lifted into the energizing position by a lever 26 and pedal &c. 28. When the infusion flows into vessel 10, a thermostat puts coils 21 and 18 into series to keep the infusion warm. The armature is provided with holes 38 to allow steam and water to escape from thereunder and prevent chattering.

Title: Improvements in or relating to the conversion of continuous filaments into staple fibre threads
IPC: D01G1/08
Filed: 1940-06-28
Abstract: 542,235. Converting continuous filaments into staple fibre yarn &c. HAYS, C. H. June 28, 1940, Nos. 1645/41, (divided out of 10991/40), 1644/41, (divided out of 11332/40), 1641/41, (divided out of 544,780) and 1646/41. [Classes 120 (ii) and 120 (iii)] Continuous filaments are converted into a staple fibre yarn or like product by passing them through two sets of drafting rollers of which the second set is driven at least 10 times as great as the speed of the first; preferably the speed of the second set is 15-20 times as great as that of the first and by this means a considerable reduction in denier is obtained. The reach is at least 5 inch and preferably 10 inch and the first set of rollers is more heavily loaded than the second. The filaments may have a basis of cellulose acetate or other organic derivative of cellulose and may be stretched or stretched and saponified and may be shrunk after stretching; stretched regenerated cellulose or polyamide filaments may be used and the filaments may be pigmented. The filaments may be drafted in a machine used for spinning worsted or natural silk with a reach of 6-20 inch, the first set of rollers comprising a spring loaded covered roller resting on a pair of fluted steel rollers and the second set comprising a spring-loaded covered roller resting on a steel roller; a conductor guides the filaments into the nip of the drawing rollers which applies a draft of 40-50 or more and the product delivered by the drawing rollers passes to a capspinning device. A linen-spinning machine may be used in which the filaments pass from a bobbin to a traverse bar and around the back of a pair of fluted rollers to the nip of the rollers and over the other roller to a conductor leading to the nip of the drawing rollers. As shown the bundle is drafted in a wet condition in a machine similar to that used in spinning flax, the filaments being led around rods 15 and through in a trough 16 to corrugated brass rollers 17 and corrugated drawing rollers 19, 20, the roller 19 being of brass and the roller 20 of wood and the drafted product being twisted by a flyer spindle 21.

Title: Improvements in or relating to regulating systems for internal combustion engines
IPC: H02P23/16
Filed: 1960-01-19
Abstract: 937,283. Electric control. ROBERT BOSCH G.m.b.H. Jan. 19, 1960 [Jan. 27, 1959], No. 1835/60. Class 40 (1). [Also in Groups XXVII and XL (c)] In a regulating system for an internalcombustion engine the fuel injection valve and the ignition timing are controlled by common electronic means responsive to both engine speed and throttle setting. Ignition control.-Unidirectional pulses derived from the alternating output from a winding 64 of an engine-driven generator change-over a monostable transistor multivibrator circuit 40, 50 in which 50 normally conducts, to cause a third transistor 30 to interrupt the circuit of the usual ignition coil. To ensure that the coil shall be fully energized at high speeds, the rectified output of a second winding 71 on the generator is applied to the monostable circuit to accelerate its return to the stable state to an extent depending on engine speed. Automatic spark advance is given by a resistor capacitor circuit 63, 62 which, acting in conjunction with resistor 64, has a delaying effect on the control impulse which is less as the speed (and hence the frequency of the generating current) rises. A mechanical connection to the throttle pedal adjusts the value of resistor 63 in a direction to reduce the amount of advance as the throttle is opened. Fuel injection control.-A cam 111 rotating with the engine cam shaft operates its contacts four times per revolution to trip a transistor monostable multivibrator 120, 130 in which 120 is normally blocked. 130 is then blocked and a third transistor 110 associated with it becomes conducting to energize a solenoid 101 and open the fuel valve. The time of return of the multivibrator and consequently the time of opening of the valve is reduced in accordance with speed by means of a voltage derived from a third winding on the generator a portion of which voltage is selected by a potential divider controlled by the throttle pedal. The arrangement is such that an increase of speed tends to reduce the period for which the fuel valve is opened, this effect becoming less as the throttle is opened.

Abstract: 223,102. Moldenhauer, E. Jan. 23, 1924. Hydraulic-seal safety apparatus for preventing explosions; valves controlled by pilot or relay valves.-A hydraulic-seal device adapted to close automatically when the conduit pressure falls below a predetermined minimum has the supply of water to flood the seal admitted through a pipe provided with an automatically-actuated valve. In the form shown, the seal comprises a casing 2 interposed in the pipe line and having a vertical partition 40 terminating short of the bottom of the casing. Water is supplied through a conduit 4 controlled by a valve 5 and exhausted through a conduit 6 provided with a valve 7. an overflow being fitted at 3. The valves 6, 7 are connected by a rod 15 to a lever 14 resting on the top of a float 11 having an opening 10 at the bottom constricted by a screw 18. The float is housed in a tank 9 subject to the pressure in the fluid conduit so that as the pressure varies the buoyancy of the float alters and the valves are acuated. To avoid the necessity of resetting the device by hand the lever may be linked to the top of the float. In a modification the float is arranged to close successively a number of electric switches so energizing electromagnets arranged to operate the control valves of a number of seals. In a further modification the sealing liquid is forced by the conduit pressure through a manually-actuated valve into an auxiliary tank in which a constant level is maintained by a ball valve. The control valve is held to its seat by a, spring so that when the conduit pressure falls the valve opens to admit water to the seal.

Abstract: 885,553. Clutch controls. CLARK EQUIPMENT CO. Jan. 22, 1960, No. 2426/60. Class 80 (2). [Also in Group XXIX] In a transmission comprising an hydrodynamic torque converter 21 connectible to a load by an hydraulically engageable multi-plate friction clutch 26, an input driven pump 80 supplies high-pressure liquid to a distributer 88 from which high-pressure liquid is supplied to the clutch 26 and low-pressure liquid is supplied to the torque converter. The torque converter, pump and distributer are enclosed in a stationary housing 20. The torque converter comprises an impeller 28 fast with an engine driven flywheel 22 and connected by gears 76, 78 to the pump 80, a turbine 30 fast with a shaft 24 connected to the input part of the clutch, and a stator 32 mounted on a stationary sleeve 68. A one-way clutch 64 is provided between the impeller and shaft 24. The pump 80 draws liquid from a sump 82 formed by the housing 20, and supplies liquid through a passage 112 to a high-pressure chamber 114 formed in the distributer 88. The pressure in chamber 114 is determined by a spring-loaded valve 122, and the chamber communicates, through a line 148 with a control valve 142 controlling supply and exhaust to a line 150 leading to the clutchactuating cylinder through a port 99 and passages 100, 102 in the shaft 24. Excess pressure in the chamber 114 urges the valve 122 upwardly to establish communication with a chamber 116 in the distributer block which communicates with inlet passages 94 leading to the torque converter as indicated by the solid line arrows in Fig. 1. The converter discharges between the turbine 30 and the stator 32 to the interior of the stationary sleeve 68, and thence through passages 95, 96 to a low-pressure chamber 118 of the distributer. The pressure in the chamber 118 is determined by a spring- loaded valve 124 and when the setting of valve 124 is exceeded it opens a passage between the chamber 118 and line 139 leading to a cooler 140 and thence to the sump 82.
