Title: Improvements in or relating to purging apparatus for cooling or refrigerating systems
IPC: F25B43/04
Filed: 1939-06-20
Abstract: 530,184. Refrigerating. STEVENS, A. H. (Armstrong Machine Works). June 20, 1939, No. 17967. [Class 29] Compression systems.-Purging apparatus comprises a,separating chamber 11 having a refrigerating jacket 13 and a float operated air discharge valve 23. As shown in Fig. 1 the apparatus also operates in conjunction with a valve 33 as an expansion valve between the condenser 2 and evaporator 3. The supply pipe 7 from the condenser enters an inlet chamber 6 and has a check valve 10 beneath an inverted bucket float 19 controlling a valve 17 admitting refrigerant liquid to the jacket 13 around the air separating chamber 11. Air and vapours entering with the liquid refrigerant collect inside the top of the float thus raising the float to close the valve 17, and pass through a restricted vent 20 to be deflected by a baffle 36 towards the refrigerated wall 14 of the separating chamber whereby the vapours are condensed and the air collects at the top of the separating chamber. As the air collects the level of the refrigerant in the separating chamber is depressed and a second float 24 drops opening the air outlet valve 23. The air is discharged to the atmosphere through a pipe 21 and inspection jar 35. The refrigerant liquid displaced by the air collecting in the upper part of the separating chamber enters the bucket float 19 causing it to sink and open the valve 17 admitting the refrigerant to the jacket 13 whence it passes through a pipe 32 to the evaporator 3. Further refrigerant and vapour from the condenser then enter the float lifting it to close the valve 17 and the action is repeated. The level of the refrigerant liquid can be inspected by a gauge glass 29. The pipe 7 may be connected through valves with both the top and bottom of a refrigerant receiver supplying the evaporator proper directly through a separate pressure regulating valve, the jacket 13 then being connected to the suction side of the compressor 1.

Title: Improvements in and relating to apparatus for determining a magnitude which varies with time
IPC: F41G5/00
Filed: 1920-07-02
Abstract: 145,724. Krupp Akt.-Ges., F. March 8, 1916, [Convention date]. Range-keepers.-An instrument for indicating a magnitude which varies with time, and particularly intended for indicating continuously the range of a moving target comprises a graduated strip G mounted on rollers H, H' in proximity to a cylinder C which is mounted on a shaft c<1> parallel to the strip. The shaft c<1> is secured to the central member E of a differential, the member D<1> of which is driven by gearing b', D from clockwork mechanism B, while the member F can be rotated by a hand-wheel f<2>. The cylinder C is marked with a number of helical lines c<3> denoting different rates of change of range, these lines diverging from a common point c<4>. The strip G can be drawn over its rollers by a hand-wheel h<2> and a pointer J, mounted on. a screw K, can be moved over the strip G by a wheel k'. The strip is adjusted until the graduation corresponding to an observed range coincides with the zero line on the cylinder C, and the cylinder is turned until the point c<4> lies against the strip, this position being determined by a stop c<5> abutting against a stop a<3> ; the clockwork is then started. The pointer J is also adjusted to the zero line. From a subsequent observation, the rate of change of range is determinable, and the intersection of the appropriate line c<3> with the strip G then indicates the range continuously, the pointer J being operated so as always to lie over the point of intersection. Corrections for time of flight of the projectile and for the lag between the issue of a fire order and its execution are applied by turning the cylinder C by the wheel f<2> independently of the clockwork. The wheel f<2> carries a drum m<1> graduated in seconds and reading against a fixed pointer a<4>, for time of flight correction,. and an adjustable pointer n<1> the distance of which from the pointer a<4> is adjusted on a seconds scale a<7> so as to be equal to the above-mentioned lag. The motions of the wheels h<2>, k<1> may be electrically transmitted to receivers at the gun. The instrument may also be used to indicate continuously the bearing of a laterally-moving target.
