Apparatus for treating the body with hot and cold water sprays comprises a spray body having discharge perforations located in sequence in at least one direction, alternate perforations being connected with a cold water supply line and a hot water supply line, respectively. Parallel cold water spray tubes 4 having aligned perforations 1 are connected to a cold water manifold 6 and alternate with similar hot water spray tubes 4<SP>1</SP> which are connected to a hot water manifold 7. The tubes and the manifolds are arranged in a frame A which is suspended by rods 10, 10<SP>1</SP> from a plate 11 above a patient supported on a plate D. The manifolds are connected to hot and cold water supply lines 3, 2 respectively, both directly through flexible hoses 8, 8<SP>1</SP>, 9, 9<SP>1</SP> and indirectly through branch pipes 17, 19. and interrupter valves 16, 18. Switch-over cocks 33, 34 in each supply line are operated by a common handle 35. In one position of the cocks, water flows directly to each manifold so that cold water and hot water are sprayed on the patient simultaneously by the tubes 4, 4<SP>1</SP>. The frame A carrying the tubes may be reciprocated in a direction transverse of the tubes by an electric motor 13 connected through a crank drive including a rod 14 with a pair of suspending rods 10<SP>1</SP> so that the areas being treated alternately receive cold and hot water in rapid sequence. In another position of the cocks, water flows to the tubes under the control of the interrupter valves 16, 18. The valves are mounted in separate chambers in a housing 26; the chambers being connected to the hot water and cold water supply lines, respectively. Each valve comprises a disc 22, 23 having diametrally opposite cut-away portions and is carried centrally by a common shaft which is rotated through gearing by the motor 13. The discs are mounted so that the cut-away portions of one are at right-angles to the cut-away portions of the other so that when one disc obturates the pipe 17 leading to the cold water tubes 4, the other disc permits hot water to reach the other tubes 4<SP>1</SP> and vice versa so that the patient receives cold water and hot water alternately.

Title: Improvements in or relating to liquid-liquid interface position controllers or indicators
Inventor: DUNCOMBE EDWARD
IPC: B01D11/04
Filed: 1951-03-19
Abstract: 702,545. Automatic liquid level control systems. NATIONAL RESEARCH DEVELOPMENT CORPORATION. March 24, 1952 [March 19, 1951], No. 6499/51. Class 38 (4) Control or indication of the position of an interface between liquids of different densities involves the derivation of three pressure differences from four conduits, two terminating in the denser liquid and two in the less dense liquid. In a liquid-liquid extraction column 1, Fig. 1, the denser liquid enters at 37 and leaves at 19a, while the lighter liquid enters at 38 and leaves at 39. To maintain constant the level of the interface 6 a valve 19 controlling the outflow of denser liquid is automatically adjusted in response to change of level as detected by pressure differences between conduits a, b, c, d, the upper ends of which are supplied from a compressed air source through a reducing valve 7 and the lower ends of which are open and equally spaced in a vertical direction. A transducer A comprising a differential bellows with an inductive type pick-off. Fig. 2 (not shown), is associated with conduits a and b to produce a voltage output 33, 34 dependent on the density of the lighter liquid. A similar transducer C associated with conduits and d produces a voltage output 33, 34 dependent on the density of the heavier liquid. A third transducer B associated with conduits band c produces a voltage output 33, 34 dependent on both densities and on the level of the interface. The voltages from transducers A and C are applied in opposition to a potentiometer D2 the resultant voltage from the slider of which is applied in opposition to the voltage from transducer B to a current responsive device. 16, which drives the potentiometer slider until balance is obtained. The slider position is then representative of the level of the interface regardless of the liquid densities. Device 16 controls valve 19 either through a pneumatic valve 18 or polarized relays controlling a motor. In a modification differential bellows are associated with the three conduit pairs and the movements of two bellows are compounded to move a contact relative to a pair of opposed contacts moved by the third bellows. The contacts control a reversible electric motor operating valve 19. An air nozzle, palette and air reaction bellows may replace the two-way switch if valve 19 is airoperated.
