Abstract: A thermionic hairpin cathode with a long operating life is made of a high melting metal wire, in which the temperature distribution along the legs is influenced either by locally increasing the radiation at a distance of 10 to 50% of the leg length from the crown or by decreasing the radiation in the immediate vicinity of the crown without changing the wire legs, possibly also by combining both measures, so that by increasing the temperature gradient in the crown region the maximum temperature is shifted close to or at the emission center.
Abstract: A desk has a vertically adjustable top and at least one vertical guide member movable upwardly and downwardly on a support or frame. A spring leg is disposed between the frame and vertically adjustable desk components. The spring leg is pivoted at one end to a guide member and its other end is braced against a curved rail. The braced end is movable on the rail and lockable in positions corresponding to accommodate various loads on the desk top. The curve of the rail is chosen so that in any position of the braced spring end, the vertical components of force acting on the guide member are equal, at least in two opposite end positions of the desk top. This results in equilibrium in each vertical position for every load on the desk top, after the spring leg has been adjusted.

Abstract: A cargo ship construction comprises a ship which has a hull structure with at least one cargo storage space opening to at least one side both above and below the water line. A cargo storage container or warehouse of substantially the size of the cargo storage space of the vessel is insertable through the opening into the space. The container is associated with a flotation arrangement such as a separate propelled vehicle which may operate on either land or water and which is provided with a lifting section for lifting cargo storage container into the section. The device may travel on land and then float out to sea and load the cargo onto the vessel either by floating it in when the vessel is ballasted so that the opening is below the water line or the device may raise the cargo above the water level and permit it to slide into the receiving space of the vessel.
Abstract: A method and device for the opening of breakable ampules, especially glass test tubes, includes a scoring tool for scratching the end which can be removed by a break-off device. A clean scratching of the ampule end can be executed, producing a smooth fracture by applying an ever constant force exerted on the ampule ends, in order to avoid lengthwise scratches in the body of the ampule from internal stresses. For this, an ampule receiver is provided, into which the ampule can be introduced as far as a stop. It is then rotated while lodged herein with the end of the ampule against the scoring tool. The scratched end of the ampule can be broken off when the ampule is advanced beyond a breaking step.
Abstract: The invention relates to a cutting and clamping sleeve contact for contacting a cable wire laterally to the sleeve axis. The sleeve contact exhibits at least one clamping through slot at the periphery of the sleeve and a cutting and clamping contact in the interior of the sleeve. Wall pieces are cut free at the wall of a sleeve. They provide a one-piece sleeve contact suitable to contact cable wires having varying diameters and multi-stranded conductors. The wall pieces are also made of a metal material, and are bent into the interior of the sleeve and form contact legs for forming the cutting/clamping contact.
Abstract: It is a question of a valve array with a number of electrically operated valves which are placed on a mounting face, common to all of them, of a rectangular prismatic connection body. Feed ducts in the interior of the valves and controlled fluid ducts are connected with feed ducts and load ducts running through the connection body. The same are connected with distribution ducts which are formed in a manifold body which is also mounted on the connection body. The valves have venting ducts which are connected with a common spent air ducts formed in the spent air duct body. Furthermore, the valve have electrical connectors which are connected with a common electronic circuit board.
Abstract: The impulse coil tester of this invention comprises a high voltage current source in which an output voltage is stably controlled, an impulse current generating part, a terminal giving the impulse current to a measuring coil, a memory once memorizing the damped vibration current waveform data of the current flowing through the measuring coil, a memory having memorized in advance the damped vibration current waveform data of the current given to a master coil and a microcomputer comparatively operating said two data.
Abstract: A miniature motor comprising a motor case having a bearing on the closed end face thereof, a stator consisting of a permanent magnet, brushes and terminals; and a rotor fixedly fitted to a motor shaft in the motor case and having core windings and a commutator; the rotor being rotatably supported by the bearing; in which the rotor and the stator are adapted so that the balance of magnetic field intensity between the stator and the rotor becomes unbalanced structurally or magnetically, thereby causing the rotor to be biased within the bearing in a predetermined positional direction with respect to the stator.
Abstract: An electrochemical gaseous measurement cell includes a housing with an anode and a cathode arranged in spaced locations in an acid electrolyte for galvanic measurement of gases which comprises an aqueous solution of an organic acid containing a polyfunctional groups suitable to yield protons during the measurement. The container, or housing, also has a membrane at an opening thereof which is permeable to oxygen.
Abstract: The invention relates to a device for automatically joining and machining assemblies consisting of several components each and retained on a work-piece carrier (4) in a transfer line with retoolable machining stations (3). In the machining station (3), the assembly components are first taken off the workpiece carrier, brought into the joining position relative to each other, retained there and machined, in particular tacked or finish-welded. To carry out these various activities and to make the machining station highly flexible, the latter has several tool carriers (22, 23) which can move in at least three axes. The tool carriers (22, 23) are each disposed in a parallel plane above or below the workpiece carrier (4) so they can travel freely. The tool carriers (22, 23) support individual tools which they can change automatically at stationary or movable tool magazines (31, 33, 34).
Abstract: The invention refers to some improvements in the foldable frames for children's pushchairs, of the type which includes the handlebar fitted slidingly over the front legs, with the folding of the pushchair being obtained with the bringing down of the handlebar. With these improvements, a very complete, light children's pushchair with a simple structure and very compact folding up is obtained. These advantages are achieved by structuring the frame on the basis of a linked triangulation formed on each side by the rear (3) and front (1) legs, and by a base frame (5), the rear leg (3) being linked by its upper end (9) on a solidly jointed flange (7) of the lower end of the brace members of the handlebar (6) and along which it slides guided by the front leg (1), the front (1) and rear (3) legs being related to each other by the base frame (5) and the front legs (1) being finished off at the top with a guiding flange (8) along which the corresponding brace member of the handlebar (6) slides.
Abstract: A method and a spark plug construction to ignite very lean fuel air mixtures with the aid of an ignition chamber with separate ignition, which is arranged in the main combustion chamber of an internal combustion engine, connected to the main combustion chamber 20 through transfer channels 21. Transfer channels may be provided which proceed tangentially, whereby rich fuel air admixtures or additional fuel is brought, valve timed, to the area of at least one transfer channel 21 outside the ignition chamber through a supply channel 24. During a compression stroke the very lean mixture in the main combustion chamber is pressed into the ignition chamber 16 through the transfer channels, which results in a very good intermixing with the additional fuel or the admixture due to the turbulent movement through the transfer channels 21 and the long path to the spark gap. This guarantees a very safe ignition.
Abstract: Automatic portable unsolderer consisting of a solenoid supplied by alternating current, a cylinder whose piston has a rod consisting the core of said solenoid, including too a reservoir and a heating member, all of them axially engaged as above-mentioned. Through the heating member end, the material that has to be unsoldered is melted and through operation of the solenoid, the piston draws back and suctions said material, which is collected, in a solid condition, in the reservoir which includes a retaining member, easily removable, and a threaded plug. On the outlet of the reservoir a one-way valve is disposed so that the air compressed by the piston, through a return spring that encircles the rod, doesn't flow through the suction conduct avoiding in such manner that the air can drag soldering material particles. The ejected air is by-passed through a side hole provided with a one-way valve that is reversely oriented.
Abstract: A helmet fastening system for protective helmets includes a drawstring system which holds the helmet smoothly to the head of the wearer in the forehead and temple areas and in the neck area simply by tightening only a chin strap. Two drawstring loops are movably arranged in an integrated guiding channel which comprises a leather pocket parallel to and attached to the helmet rim. The length-adjustable chin strap form a closed drawstring system outside the guiding channel. The tightening of the chin strap leads to the spreading of the force between the chin strap, and two chin strap loops of the drawstring system so that the protective helmet and the leather pockets forming the guiding channels fit tightly in the neck and forehead areas of the wearer. A slipping of the protective helment even under the influence of external force is substantially impossible.
