Patent FI-972983-A (FI)
Inventor: PITKAENEN JORMA ANTERO
IPC: F23M/
Filed: 1997-07-14
Abstract: The invention relates to providing a vertical expansion joint in a refractory lining, where the lining is made from refractory casting material. In the previous solutions it has been indispensable to saw the formed plywood used in manufacturing refractory linings into small pieces, making the manufacturing of the lining slow and cumbersome. Further, it has not been possible to reuse the moulds, and at the vertical corners, acute angles of 90 degrees were formed which were easily damaged. In the use according to the invention, the vertical expansion joint material 4 has been sealed and fastened to the outer mould material 3 by means of a particular fastening profile 5, fastened to the outer mould material, said profile enabling rounding of the vertical corners and reduction of risk of damages. Further, form plywood may be used in as long strips as permitted by the dimensions of the plywood, and the plywood may be reused. The use according to the invention is utilised e.g. in mounting of a refractory lining at the membrane tube wall in a power plant boiler.

Abstract: 924,803. Storing liquefied gas. CONCH INTERNATIONAL METHANE Ltd. June 20, 1961, No. 22193/61. Class 8(2). A tank for liquefied gas, e.g. natural gas, nitrogen or helium, comprises a container constructed of dimpled, thin metal sheets surrounded by and supported on load-bearing surfaces which are part of a thermal insulation system, spaces between the outside of the dimples and the load-bearing surfaces being filled with a resilient filler, e.g. polyurethanes and polyvinyl chlorides, particularly of the foamed type, or resin bonded fibres such as glass fibres. As described a prismatic tank has a floor 9 and side walls 7 formed from dimpled stainless steel sheet fixed at 10 and 8, respectively, to plywood panels 5 and 4 which with further plywood panels 6 and 3 are bonded to balsa wood panels 2 and 1 of the insulation system. The corners between the floor and side walls are sealed by gutter-like, transversely corrugated strips 11. The resilient filler is shown as 13 between the floor and side walls 9 and 7 and the plywood panels 6 and 3. The space between the strips 11 and the panels 4 and 5 may also be filled with reslient filler. The metal sheet may, alternatively, be made of aluminium or its alloys or copper or its alloys and the thermal insulation may be quippo, cork, foamed plastics, glass, asbestos, jute fibres, mineral wool or cellular gypsum. The metal sheet may form a barrier round another vessel for the liquefied gas to prevent escape of the gas in case of rupture of that vessel; the dimples on the inside of metal sheet may in this case also be filled with resilient filler. Specifications 919,587, 924,801, 924,802 and 924,804 are referred to.

Title: Logical circuit arrangements
IPC: B31B23/00
Filed: 1967-01-09
Abstract: 1,127,533. Transistor logic circuits. NATIONAL CASH REGISTER CO. 9 Jan., 1967 [4 March, 1966], No. 1136/67. Heading H3T. [Also in Division H1] In a logic circuit including two series connected transistors 16 and 17, a feedback circuit 39 is connected between the collector of the transistor 16 and the base of the transistor 17 such that variation in the collector voltage of the transistor 16 is compensated for by an appropriate variation in the impedance of the emitter-collector path of the transistor 17. The voltage at the base of an input transistor 18 is clamped by diodes 24 and 28 so that when all of the inputs at 21 are at a high level the transistors 16-18 conduct to give a low logical output at terminals 37, 38 which are connected together. When one or more of the inputs goes to a low level the input transistor 18 and transistors 16 and 17 are turned off to give a high logical output so that the circuit performs a NAND function. Overshoot of the low level output when the transistor 16 is switched on is prevented by the feed back network 39 since the change in output level at C is capacitively coupled via the reversely biased diode 29 to the base of the transistor 17 to control the conduction of this transistor so as to bias it out of the saturated region in which it had been initially biased. During turn on of transistor 16, diode 19 conducts to divert some of the current which had been passing through the resistors 31, 33 so as to alter the bias of the transistor 17 and set the low level output. Any variation of the low level output which may occur, e.g. due to supply variations, is then coupled via diode 19, resistor 31 and diode 29 to the base of the transistor 17 which changes in impedance to off-set the change. Transistors 16 and 18 are arranged so as not to be biased in the saturated region so that delays in switching off due to charge storage effects are eliminated. In a modified circuit (Fig. 3, not shown), having a transistor AND gate (20a) replacing the diodes 20 the emitter-collector path of a further transistor (13) is connected across the base emitter of the transistor 16 so as to ensure that this transistor does not work in the saturation region. Also the diode 19 is replaced by the base-emitter path of a transistor (19a) so that the diverted current is passed via the collector of this transistor directly to terminal 27. The output of several of these logic circuits may be connected in parallel so as to perform AND functions or may feed the input of a similar circuit. The circuits may be formed as integrated structures (Figs. 2 and 7a, not shown), where the diodes 24, 28 and 29 are shown as transistors (24a, 28a) connected as diodes, or transistors (24a, 29a) using their base-collector, base-emitter junctions as diodes.

Abstract: 1490481 Ion beam apparatus; ion implantation COMMISSARIAT A L'ENERGIE ATOMIQUE 13 Jan 1976 [22 Jan 1975] 01157/76 Heading H1D and H1K Increased uniformity in charged particle implantations, e.g. ion implantation in the manufacture of MOS transistor circuits, is achieved by sweeping the beam of incident particles over the surface of the specimens in two perpendicular directions, and simultaneously moving the specimens in a generally epicyclic manner. As shown, the motor driven shaft A rotates the plate P in which is mounted the further shaft A<SP>1</SP>, which is simultaneously caused to rotate about its axis by engagement of the gear wheel 34 with the fixed rack 36. The pivot 42 terminating the shaft A<SP>1</SP> permits the specimen support plate P<SP>1</SP> to be secured to the shaft either perpendicular thereto, as shown, or inclined at angle of up to 15 degrees thereto. The plate is preferably set at that angle which, by prior calibration, is found to result in a maximum of back-scattering of the particles, which is stated to correspond to the angle at which particle channelling effects are a minimum, e.g. an angle of 7 degrees + 1 degree for a silicon substrate bombarded by α particles or protons. The incident-beam, which is stopped down by the diaphragm 20, is scanned over the target by electromagnetic deflection, the current received by the target being measured by device 50, and secondary electrons emitted by the specimen being removed by electrode 22.

Class 38 (4). - A stable direct voltage is produced between terminals 76 and 78 from an A.C. supply of variable voltage and frequency applied to terminals 2 and 4. A condenser 6 and the primary of a saturable transformer 12 connected in series across the supply terminals are resonant at a frequency below that of the supply. The output of transformer 12 is rectified at 28 and applied to a non-linear bridge circuit 48 including tungsten filament lamps 54 and 60. By adjustment of a rheostat 26 the voltage applied to bridge circuit 48 is such that its output is a maximum so that rate of change of output voltage with respect to input voltage is zero. A condenser 21 and an inductance 22 connected in series across the secondary of transformer 12 are resonant at a frequency above that of the supply and provide compensation for frequency variations. A more stable A.C. supply may permit condenser 6 and the frequency compensating circuit to be dispensed with.
