Title: Supporting planes of flying machines
IPC: B64C3/26
Filed: 1920-07-10
Abstract: 148,796. Goebbel, H. J. May 1, 1914, [Convention date]. Void [Published under Sect. 91 of the Act]. Planes, construction of: framework.-The planes of aircraft are formed with upper and lower surfaces rigidly secured to an intermediate framework consisting of wave-like strips set on edge, the crests of adjacent strips being secured together, and all external bracing dispensed with. This system of construction may also be applied to aeroplane bodies. The stays 1, Fig. 1, may be of sheet metal such as steel, aluminium, or duralumin, or they may be of plywood, and they are joined together by riveting, glueing, welding or soldering. The coverings may be of sheet metal, or of wood strips glued together crossways, and are secured to the stays 1 by glueing, when the plane is wholly of wood, or by point welding, riveting &c. when of metal. The stays 1 are arranged across the section of the plane and are pointed at their front and rear ends to enable the edges of the coverings to be secured together. When a non-solderable covering is secured to a solderable metal frame, the covering d., Fig. 10, is bored at intervals to take flanged metal thimbles f which are slotted to embrace the strips a of the frame. Solder is then introduced into the spaces i. When the member a is of wood or aluminium, metal strips may be passed through slots in and over notches in the edge of the member a at the points embraced by the thimbles f so that a soldered joint may be made. Fig. 13 shows one form of metal strip having a punched-out portion p adapted to be passed through a hole in the member a and expanded over the edges of a hole q<1> in the metal strip. Screws may also be used for securing the coverings to a wooden frame, the points of attachment on the frame being reinforced by strips of wood and metal clamps.

Title: Improvements in or relating to lung-controlled breathing apparatus
IPC: A62B9/02
Filed: 1957-07-01
Abstract: 862,367. Respiratory appliances. DRAGER, O. H. July 1, 1957 [June 30, 1956], No. 20701/57. Class 81 (2). Lung-controlled breathing apparatus comprises first and second chambers 8, 9 separated by a wall 7 movable in response to increased pressure in the second chamber 9 on exhalation to open a pressure-reducing valve 5 in an inlet 1 for gas under pressure to the first chamber, the first chamber being connected to the respiratory organs of the user by an outlet 12 to which the second chamber is also connected by a further duct 14 having a valve 13 which permits exhaled gas to pass into the second chamber. Gas under high pressure enters a chamber 8, on one side of a diaphragm 7, through a bore 3 and a valve seat 4 on which bears a spring-loaded valve member 5. On inhalation through a pipe 12 connecting the user to the chamber 8, the diaphragm 7 moves inwardly of the chamber 8 and operates a lever to open the valve member 5. On exhalation through the pipe 12, gas opens a non-return valve 13 and flows into a second chamber 9 on the other side of the diaphragm 7. An exhalation valve 21, the closure pressure of which is such that a positive pressure is maintained in the chambers 8 and 9, permits gas to be exhausted to atmosphere. The exhalation valve 21 is connected through a spring 22 to an aneroid capsule 24 exposed to the atmosphere, so that with increase in altitude the closing pressure of the valve 21 is increased. Thus at increased altitudes the pressure in second chamber 9 rises and is transmitted through the diaphragm 7 to gas in the first chamber 8. A bleed aperture 15 in the non-return valve 13 allows the gas pressure on both sides of the diaphragm 7 to be equalized when the apparatus is not in use.

Title: Improvements in and apparatus for the removal of carbon monoxide from gases containing hydrogen
IPC: C10K1/12
Filed: 1936-07-31
Abstract: <PICT:0478973/III/1> In removing carbon monoxide from gases containing hydrogen by washing them with an ammoniacal cuprous salt solution, the spent solution is regenerated by expelling therefrom carbon monoxide and any carbon dioxide in at least two different degrees of vacuum, the highest vacuum being employed in the last stage.  The action of the vacuum in the single stages may be enhanced by leading in inert gases.  Preferably, the gases obtained from the second or a later vacuum stage are passed into a previous stage.  A spent solution from the absorption of carbon monoxide from gases containing hydrogen, which contains ammonia, cuprous and cupric copper and carbon dioxide, flows at 30 DEG  C. from a pipe 4 through packed containers 1, 2 and 3 and interposed siphons 7 and 10, being withdrawn through a pipe 13 for further use.  The gas set free in container 3 under the highest vacuum is sucked by a pump 21 into the container 2 in which a lower vacuum prevails and together with the gas evolved in container 2 is then sucked by a pump 18 into container 1 where the lowest vacuum prevails.  The combined gases containing carbon monoxide and carbon dioxide are sucked by a pump 15 through a pipe 16 to its place of use.
