Title: Improvements in and relating to apparatus for starting and controlling electric discharge devices
IPC: H05B41/232
Filed: 1943-01-15
Abstract: 586,152. Control systems for space discharge apparatus. BRITISH THOMSONHOUSTON CO., Ltd. Jan. 15, 1943, No. 762. Convention date, Jan. 22, 1942. [Class 38 (iv)] To obtain a sufficient starting voltage for a discharge device, such as a fluorescent lamp, irrespective of the heating of its electrodes, the stabilizing reactance 16 is inductively related to a winding 15 on a core 9 which comprises a bridged air gap and is energized through a linear reactor which may have an air gap core. This arrangement produces in the winding 15 a peaked impulse at each instant of maximum supply voltage which is superposed on the winding 16 with transformer effect. When the discharge device has started, the presence of a condenser 7 causes a back e.m.f. in winding 15 which reduces the losses in the elements 9, 17. A similar circuit is described comprising an additional auto-transformer to step up the supply circuit voltage applied to the main circuit and providing lower voltage tappings for the peak-producing circuit. Fig. 8 shows an arrangement for two lamps wherein a lamp la, taking lagging current, is adapted to start immediately on closure of switch 6. It is in series with a high reactance secondary winding 45 on the transformer 40 and also with the winding 15 providing'the peaked voltage for starting the lamp 1, which takes a leading' current.

Title: Improvements in the preparation of cellulose from wood and other lignocellulosic materials
IPC: D21C3/18
Filed: 1940-01-16
Abstract: 538,023. Refining cellulosic materials. BATE, S. C. Jan. 16, 1940, No. 922. [Class 2 (ii)] Lignocellulosic materials are treated with a chlorite and then with an alkali solution in order to obtain a cellulose product substantially free from lignin. The purified cellulose product may be used for the manufacture of cellulose derivatives such as cellulose acetate. Sodium or calcium chlorite, or a chlorite of another alkali or alkaline earth metal or a chlorite of an organic amine may be used. Treatment with chlorite is preferably effected under slightly acid conditions at 75-100‹C. but various conditions of acidity or alkalinity and temperature may be adopted. After the chlorite treatment, the lignin conversion products may be removed by treatment with hot or boiling caustic alkali of 6 per cent. strength or less, or with a cold caustic alkali of 10-15 per cent. strength or more. Treatment with hot dilute alkali may be followed by treatment with cold or more concentrated' alkali. After the chlorite and alkali treatments, the cellulose material may be subjected to a bleaching treatment with a chlorite, hypochlorite, gaseous chlorine, or other bleaching agent. In an example, wood wool is mixed with water containing a little hydrochloric acid. The mass is heated and sodium chlorite is added in small quantities at intervals, each new lot being added when the last has been exhausted. The addition is stopped as soon as excess persists in the liquor. The liquor is removed and the cellulosic material is subjected to the action of a boiling dilute caustic soda solution and then to the action of,a cold but more concentrated solution of caustic soda. The material is heated to 120‹C. with 0.5 per cent. caustic soda solution and then bleached with hypochlorite or chlorite. The purified cellulose product may be used for the production of cellulose acetate. It may be pre-treated with acetic acid containing sulphuric acid and then acetylated with acetic anhydride, acetic acid, and sulphuric acid.

Title: Method and device for determining an orientation related to a mobile system particularly the line of sight in a helmet sighting
Inventor: ZIMMER PIERRE
IPC: G01S3/02
Filed: 1997-03-20
Abstract: A method for determining a line of sight from a sighting device mounted on a helmet provided with a sensor (2) with three orthogonal magnetic coils, in relation to a reference attached to an aircraft and having the form of a transmitter (1) having three orthogonal magnetic coils. According to the method, the cockpit is first magnetically mapped. For this purpose, sets of field measurements detected by the sensor for the fields successively produced by the transmitter's three coils for various known positions and attitudes of the sensor in the cockpit are established and memorized. Then, the cockpit is magnetically modelled on the basis of said measurements. In flight, the matrix of measurements, combined with a transmitter transmission cycle initiated when the pilot confirms a directional line of sight determined in relation to his helmet, allows the orientation of said line of sight in the aircraft reference to be accurately calculated on the basis of the model previously made. The method can be used for sighting from helicopters where the cockpit causes disturbances because of field reflexions from metal components.

Title: Pulse transmitter
Inventor: KAWAMURA YOSHIHIRO
IPC: H03K17/968
Filed: 1981-01-06
Abstract: PURPOSE:To achieve high pulses with high accuracy and long life, through the use of code disc of low pulse, by using a prism so that light from a light source passes through the slits of code disc twice. CONSTITUTION:Luminous fluxes which pass through a code disc 4 out of light from a light emitting element 2 are denoted as 19, 20 and the luminous fluxes pass through a prism 18 as 19', 20'. Since the up-and-down directions of the luminous fluxes 19, 20 and 19', 20' are replaced, the luminous fluxes 19', 20' move toward the arrow of B when the disc 4 moves to the arrow A. Thus, the luminous fluxes 19', 20' and the slits of the code disc 4 can be regarded as being moved relatively in the double speed of the code disc 4. Thus, pulse signals twice the number of slits on the code disc 4 can be obtained. Further, a plurality of detection sections can be provided.

IPC: F01D5/18
Filed: 1998-01-05
Abstract: PROBLEM TO BE SOLVED: To enhance a heat transfer rate in a thermal entry region regarding a cooling passage of a moving blade inside for a gas turbine. SOLUTION: Cooling passages 2, 16, 17 communicate mutually inside a moving blade 10, and a cooling passage enlarged part 1 of width W1 is connected to a passage 2 of width W2 with a stepped part 3 within a thermal entry region X in the vicinity of a hub part 14 to narrow a passage. The W2 is sustantially same to a W in the prior art, and W2 /W1 is within the range of 0.5-0.8. Cooling air 20 flows from a blade bottom 12 into the cooling passage enlarged part 1, the passage is narrowed suddenly, at the stepped part 3, and separation and readhesion of flow are generated to enhance a heat transfer rate in this part remarkably. Then the cooling air 20 passes through the passage 16, 17 from the passage 2 to flow out to the outside from its tip end.  The heat transfer rate in the thermal entry region X is remarkably enhanced thereby, cooling for the hub part 14 is strengthened, and a blade life is improved.

Title: Semicondutor integrated circuit
Inventor: KITAMURA NOBUAKI
IPC: H01L27/00
Filed: 1982-01-06
Abstract: PURPOSE:To test a logic circuit having a multiplicity of pins at high speed, by providing, in an IC having a logic circuit and first terminals coupled to nodes thereof, second terminals, third terminals for supplying selecting signals, smaller in number than the first terminals, and a node selecting circuit disposed between the second terminals and the nodes. CONSTITUTION:With a mode selector MSC set into the probing mode, testing data are fed from a circuit B into FFs corresponding to any desired pads thereby to set all the data. After an internal logic state is established, the output data are delivered to the respective pads and compared with expected values to test all the pins thereby to complete a function test. In the case where device to be tested has 150 input pins, 150 output pins and 20 power source pins, i.e., a total of 320 pins, this constitution only requires 19 additional pins besides 20 power source pins. Accordingly, the number of used pads can be decreased, and the damage to a wafer can be reduced. In addition, it is possible to select any one of the FFs in probing, and when a new data is set, the operation can be effected by selecting only desired FFs. Therefore, an IC having a multiplicity of pins can be tested at high speed.
