Title: Improvements in and relating to forced flow steam generators with working fluid re-circulation
IPC: F22B29/12
Filed: 1969-07-25
Abstract: 1280234 Steam generators SULZER BROS Ltd 25 July 1968 [25 July 1968] 37583/69 Heading F4A In a forced flow steam generator which comprises a pre-heater for feedwater, on evaporator within a combustion chamber, a water separator connected to the evaporator outlet, and a pump to recirculate water from the separator to the evaporator at part load, there are provided means in which, at least in the tap load range of the generator, some of the steam leaving the evaporator is condensed on at least some of the pre-heated water, and means to deliver the condensed steam and feedwater to the evaporator. As shown feedwater is fed through a preheater 2 to a mixer 3. At temperatures equal to the saturated steam temperature at the evaporator outlet 7, a mixture of steam and water is fed to the water separator 8, the separated steam flowing to a superheater 11 and a turbine (not shown), and the separated water flowing through a non-return valve 14<SP>1</SP> to the mixer 3. A pump 4 recycles the separated water together with the pre-heated feedwater to the evaporator inlet 5. At temperatures above the saturated steam temperature at the evaporator outlet 7, part of the generated steam is fed to the mixer 3 via a by-pass line 12, non-return valve 14 and control valve 13, in which mixer it condenses on the pre-heated feedwater. The mixture is then recycled by pump 4 to the evaporator inlet 5. To improve mixing, the mixer 3 contains baffles in the form of perforated plates. Irrespective of the type of operation of the generator, a quantity of steam is continually fed from the evaporator outlet 7 to the mixer 3 to act as a barrier against return flow of water. The evaporator 6 is formed by parallel vertical tubes which line substantially the entire height of the combustion chamber. In another embodiment, Fig. 2 (not shown), the water separator and the mixer are combined to form a single unit. A control system, which comprises a temperaturesensitive element (23), controller (24), pressuresensitive element (25) and a transmitter (26), ensures that a distributer (21) which divides the flow of feedwater in two, is so adjusted that the temperature of the steam in line (22) remains between 10‹ and 20‹ C. below the saturated steam temperature.

Title: Arrangements for teaching the resuscitation of unconscious persons by insufflation methods
IPC: A61M16/00
Filed: 1959-11-06
Abstract: 882,545. Resuscitation training. HESSE, H. Nov. 6, 1959 [Nov. 10, 1958; June 10, 1959; Sept. 7, 1959; Oct. 10, 1959], No. 37744/59. Class 81 (2). An apparatus for use in teaching mouth-tomouth resuscitation comprises a representation of a human trunk and head with means for indicating whether respiration is being correctly applied. In a simple form the head has mouth and nose passages 20, 21 communicating with a conduit 22 leading to a slide valve 4 which is so connected to the chin 2a that, when the chin is correctly raised, the valve provides communication between the pipe 22 and a pipe 25 leading to a sac 15 representing the lungs. If the chin is lowered, the valve moves to a position which gives connection with a tube 26 leading to a sac 16 representing the stomach, thus reproducing the effect of lowering the chin which causes the tongue to block the trachea. Two rotary valves 11, connected in the tubes 25, 26, are connected between the two parts 8, 9 of the base board, which are hinged about the common axis of these valves. The valves are so arranged that, unless the head is moved back to the correct position, there is no communication with the sacs 15, 16 and insufflation is impossible. In other forms of the invention the movement of the chin controls a pinch cock type of valve and there may be an additional valve, in the tube leading to the stomach, which opens only when excessive pressure is applied. It is also proposed that the indications of correct or incorrect procedure should be derived electrically.
