Title: Improvements in or relating to thermionic cathodes
IPC: H01J17/06
Filed: 1939-01-10
Abstract: 523,622. Thermionic cathodes. SCHALLREUTER, W. L. W. Jan. 10, 1939, No. 868. [Class 39 (i)] A cathode for use in a gas or vapour filled discharge tube comprises one or more conductors formed so that different parts of the conductor or conductors act as boundaries to a small space left between said parts or between the conductors ; a filling material such as barium hydroxide or carbonate is deposited in the space and the device so formed is mounted as soon as possible in the tube wherein it is to be used: the tube is now filled with an inert gas-say hydrogen at 1 mm.-and a discharge current is passed just sufficient to clean and reduce the conductor or conductors ; the tube is thereafter exhausted, refilled with an oxidizing atmosphere and a heavy discharge passed, so as to transform the filling into a highly emissive coating firmly adhering to its mount. The conductor &c. may consist of a helix or two helices one within the other, the inner of thicker wire than the outer. They may form a heating current circuit for the cathode or the latter may be heated by the discharge only. The filling is initially placed on the inner helix. In place of helixes tubes, rods, plates or cylinders may be used. The conductors may be of tungsten, molybdenum, nickel, iron, platinum, rhodium or conducting refractory oxide. The oxidizing atmosphere may be oxygen, air, carbon monoxide or dioxide. A sleeve of insulating material surrounds the cathode to act as a sputtering shield for the envelope end.

Title: Preparation of homogeneous luminescent layers
Inventor: PIWONKA RICHARD
IPC: H01J9/22
Filed: 1961-01-10
Abstract: A process for the preparation of a homogeneous layer of a luminescent substance on a carrier, e.g. in electron microscopes or image converters, comprises sedimenting the luminescent substance from a suspension in an aqueous solution of a silicate or a phosphate and when the luminescent substance is settled on the carrier, introducing a solution containing a silicate binding agent and a coagulant into the immediate vicinity of the deposited luminescent layer by means of a capillary tube.  The solvent in the solution containing a silicate and a binding agent can be aqueous hydrochloric acid.  The coagulants used can be alkali metal or alkaline earth metal salts.  In a specific example the luminescent material is silver activated zinc cadmium sulphide which is suspended in an aqueous solution of potassium silicate, and the binding agent and coagulant are potassium silicate and barium nitrate respectively in aqueous hydrochloric acid. After the above process the liquid is poured off and the carrier is dried at approximately 80 DEG  C.

IPC: C12N15/57
Filed: 1993-07-29
Abstract: DNA sequences are disclosed encoding B. amyloliquefaciens and B. subtilis subtilisins and B. subtilis neutral protease. Using DNA derived from these sequences as hybridisation probes, genes for these and other closely related enzymes can be cloned from procaryotic sources, identified by their carbonyl hydrolytic acitivity and expressed in a suitable recombinant host. Moreover, the DNA can be mutated to produce enzymes with altered characteristics which can be screened for to identify desired changes, and thereafter the modified enzymes obtained by expression of the muted genes in suitable recombinant hosts.

Title: Manufacture of ultra-low iron-loss and grain-oriented silicon steel sheet
Inventor: KOMATSUBARA MICHIRO
IPC: C21D8/12
Filed: 1985-01-08
Abstract: PURPOSE:To reduce the iron loss of a titled plate without lowering its magnetic flux density by adding an impact force produced by vibrations, to the forsterite film of the surface of a grain-oriented silicon steel plate provided previously with finish annealing. CONSTITUTION:A fluid is injected at a discharging speed of 10<3>-10<6>cm/sec from a discharging port at a distance of <=50cm from the film of forsterite to break the forsterite film without forming a recess in the base-metal surface of a steel plate. In addition to the breaking of the forsterite film and a fine strain introduced just beneath the film; an electromagnetic wave focused by a zone-plate method, noncoherent within a range of its wave length ranging from the far ultraviolet rays to the far infrared rays, is continuously irradiated to introduce the fine strain without causing recesses in the base-metal surface of the plate. In this way, the iron loss of the plate is reduced without lowering its magnetic flux density, and a steel plate, free from deteriorations of its space factor and its iron loss at the time of laminating, is easily and efficiently manufactured.
Patent JP-S61161363-A (JP)
Title: Feed water heater
Inventor: TAKASU SHIGETOSHI
IPC: F24H1/18
Filed: 1985-01-08
Abstract: PURPOSE:To prevent the service life of the titled device from being reduced due to sulfuric corrosion and the like by a structure wherein an open type thermosyphon equipped with an orifice is employed as a heat transfer element. CONSTITUTION:The water in a container 1 is evaporated by the heat H of exhaust gas. The resultant vapor V travels upward on the low temperature (low pressure) side so as to condense onto the inner wall of the container protruded in a feed water tank in order to turn into water W, which falls along the inner wall of the container by gravity and to be evaporated again, resulting in constituting a circulating system. Thus, the heat transfer from the exhaust gas side to the feed water tank side is efficiently done through the evaporation and condensation of water in the container 1. The temperature of a heat transfer surface, with which exhaust gas contacts, can be controlled by changing the heat transfer rate during steady actuation through the change of the length (l) of a top cap 3 in such a manner that the cap with its length (l) shorter is used when the temperature of exhaust gas is low at all times, while the cap with its length (l) longer is used when the temperature of exhaust gas is high at all times. In addition, because of an orifice at the outlet of a thermosyphon 5 (not shown), the inner wall of the container 1 is automatically cleaned and little adhesion or deposition of scale is resulted.

The grooves 5 provided in this way are melted with the beam 4,  whereby the molten metal consisting of a desired component ratio is obtained.

Abstract: PURPOSE:To facilitate the frequency switching and to prevent the production of malfunction of a CPU by clearing a latch circuit when an output of NOR circuit is a high level signal so as to inhibit a clock signal selection function in a clock signal selection circuit thereby outputting a high level signal. CONSTITUTION:In setting a data bit information D0 signal to an optional I/O port, the D0 signal is impressed to an input terminal D of a DFF 17.

Title: Intake air flow rate detector for internal combustion engine
Inventor: MIZUTA KAZUYUKI
IPC: G01F1/32
Filed: 1978-01-06
Abstract: PURPOSE: To ensure a stable flow rate detection over the whole running range of an internal combustion engine by restraining pulsations of an air flow in the vicinity of Karman's vortex detecting portion thereby to generate stable vortexes even in the range of low manifold vacuum.  
     CONSTITUTION: The air sucked into an air inlet tube 1 generates at the back of a vortex generating column 3 the Karman's vortexes in number corresponding to the flow rate and is further sucked through a throttle valve 2 into the intake valve of an internal combustion engine. The vortexes thus generated are mixed with the corresponding frequency signals for the ultrasonic waves of an oscillator 4 and are received as at 5 so that they are converted by a processing circuit 5a into the voltage output corresponding to the air flow rate. An air tank 6 is made to have communication with the inlet tube 1 through a communication pipe 7 so that it can also be communicated with the negative pressure surge generating source downstream of the valve 2. Thus, it  is possible to preset the opening position in an effective manner. Moreover, it is possible to generate regular vortexes, while restraining the pulsations of the intake air flow, over a wide range of  the manifold vacuum.
