IPC: A61M11/02
Filed: 1979-04-17
Abstract: Respirator apparatus for assisting in the respiration of a patient who is indisposed or whose lungs are damaged includes a modular system to which various components may be added so that the same apparatus can be modified for various purposes. The respirator apparatus is a modular system comprising a basic unit, namely a drug atomizer and a control valve associated therewith which regulates the flow of air or oxygen to the drug atomizer. A flexible tube is fluidly coupled between a connector provided on the control valve and a pressure supply source. Associated with this modular system are a respiration pressure control valve which is connected to the drug atomizer control valve, an injector member fluidly connected to the drug atomizer, a flexible tube fluidly intercommunicating the respiration pressure control valve and the other end of the injector member and an expiration valve mounted between the respirator mouthpiece and the drug atomizer by which the counter-pressure presented during expiration can be steplessly adjusted.

Abstract: The present invention relates to a process for the recovery of metals from the scrap from nickel-cadmium electric storage batteries or other products which in addition to cadmium also contain organic substances and metallic components made of iron, nickel or other metals. The process involves opening the batteries and emptying them of any free electrolyte, drying the scrap, removing the organic substances by pyrolysis at an initial temperature followed by condensation. The pyrolysis and distilling-off operations are performed in one and the same furnace by the successive and preprogrammed raising of the temperature inside the furnace, for example in stages, in order to produce a residue inside the furnace in the form of nickel and iron scrap. Pyrolysis takes place in a controlled atmosphere, requiring the introduction of an inert gas such as nitrogen with the addition of between 3 and 12% of oxygen, if necessary in the form of air. Pyrolysis is made to occur by raising the temperature inside the furnace from about 100 DEG  C. to an initial temperature of about 400 DEG  C. or 500 DEG  C. The vaporization of the cadmium takes place at a second temperature of up to about 900 DEG  C. in the presence of a reducing protective gas. The cadmium vapor is condensed and the liquid metal is cast into cadmium rods.

Abstract: A rail for a track-bound vehicle comprising a number of lateral flanges, which can cooperate with a substructure, the flanges extending in an outwards direction from an essentially vertically arranged web provided with a foot, and a portion of a runway rail forming part of a head of the rail and connected with the web. This makes possible a reduction of excavating and substructure work, when laying rails, and a simplified maintenance of the tracks, and in addition also reduces the required number of sleepers. The lateral flanges as seen in the transverse direction relative to the web project to a larger extend than the foot, so that the load operating on the rail will essentially be absorbed by the substructure cooperating with and substantially being located in the area of the lateral flanges.

Abstract: At a moveable frame there is rotatably mounted a driveable winding core. The one end of a tension-resistant winding band is connected with this winding core, and such winding band is wound-up upon a band spool. This band spool is rotatably mounted in arm members of the frame. Acting upon the shaft of the winding core is a jaw brake. The shaft of the band spool is likewise brakeable and blockable by means of a jaw brake. The frame together with the winding core, band spool and the therebetween traveling winding band can be transported. For winding-up flat products or the like the shaft of the winding core is driven, and the jaw brake effective upon such shaft is opened or retracted. The band spool is slightly braked by the jaw brake associated with the shaft of the band spool. The flat products are infed to a winding gap and together with the winding band which is under tension wound-up upon the winding core. After formation of the wound product package the winding core and the band spool are blocked by means of their related jaw brakes. The package is held together by the winding band which is retained under tension.

Abstract: The vehicle alarm has an elastic tube contg. a deformation sensor with a circuit triggering an alarm when a defined degree of deformation is exceeded. It is applicable to safety of passengers in buses etc. when the doors are closing, and has a high degree of sensitivity independent of time and ambient influences. The tube (2) deformation sensor consists of a light source (3) and receiver (4) between which a light beam acts as a signal medium. A circuit dependent on the output signal of the light receiver regulates the intensity of the light source so as to compensate a variation in the light intensity received by the receiver. The circuit starts to react after a certain delay following the beginning of the variation in the receiver signal caused by the intensity variation. -

Abstract: The apparatus comprises a float (17), a generator (21) and a motion- transferring mechanism (26-45) therebetween comprising an energy accumulator, e.g. a helical spring (36), which becomes wound up or tensioned as a result of the upward movement of the float (17) in the float chamber (14). A tripping mechanism (35) becomes operative when the helical spring (36) has become so tightly wound that it overcomes the locking force of the tripping mechanism (35), the released spring force thereby driving the generator. The float (17) is incorporated in a float chamber (14) built into a boat (13), a buoy or the like, the chamber having a water inlet pipe (5) open toward the water. The generator (21) and motion-transferring mechanism (26-45) are disposed in a housing (1) which also comprises the float chamber (14). The housing is preferably mounted in a cradle-shaped step bearing (4) which can be mounted in a boat, buoy or the like, which permits the position of the housing (1) and thereby the float chamber (14) to be adjusted about the axis of the cradle so that the float chamber can be brought into a desired vertical position independently of the slope of the boat hull. <IMAGE>

Abstract: A rheometer for studying the elastic properties of a material has two coaxial shafts (23, 29), the mutually adjacent ends of which are provided each with one measuring probe (25, 32) adapted to engage with a sample (P) of the material. One shaft is rotatable and the other is stationary, and at least on the latter magnetoelastic ribbons are fixed whose permeability is changed upon transmission of a rotary force from said rotary shaft to said stationary shaft via the sample between said measuring probes (25, 32). The change in permeability can be read by means of primary and secondary coils surrounding said shaft in a contactless manner and connected to a voltage source and a measuring equipment, respectively. To drive the rotary shaft, use is made of an electric motor (21), but it is also possible to replace the entire shaft by a magnetoelastic tape or rod surrounded by a coil connectible to a voltage and current source. This arrangement can be used also as a stationary shaft for checking the torque thereof.
