Title: Improvements in means for supplying air to the boiler furnaces of steam-driven aircraft
IPC: B64D27/24
Filed: 1920-03-29
Abstract: 141,685. Wagner, R. April 16, 1919, [Convention date]. Addition to 140,081. Propelling.-In steam-turbine installations for aircraft as described in the parent Specification, the combustion air for the oil-fired boilers is supplied through passages open at their front ends so that a draught is induced by the flight of the aircraft, a blower being used when the aircraft is stationary or flying at high altitudes. Fig. 2 shows an aircraft body g having air passages i open at the front ends f and leading at their rear ends to the air opening k of the furnace burner. The blower n receives air through a passage p and forces it through a nozzle r. The waste gases pass through an air-preheater e to passages m. In a modification, the drum a of the boiler is arranged longitudinally, instead of transversely, and the blower draws in air through a separate duct opening in the direction of flight. In the form shown in Fig. 5, the additional air is supplied to several smaller nozzles w; or it may be supplied directly to the combustion chamber through tubes x, Fig. 6. The main air opening k may be expanded by mechanical or other means when the additional air is being supplied thereto.

Title: Improvements in or relating to oscillatory systems for clocks and watches
IPC: G04C3/027
Filed: 1961-03-15
Abstract: 926,511. Clocks and watches. SIEMENS & HALSKE A.G. March 15, 1961 [March 15, 1960], No. 9512/61. Class 139. [Also in Group XL(c)] In a timepiece in which the pendulum or balance is maintained in oscillation by the interaction between relatively movable coil and magnetic members, the coil S, Fig. 2, is in series with a battery B and a tunnel diode T. The voltage induced in the coil as the balance or pendulum swings in one direction opposes that of the battery so that an increased current flows through the tunnel diode T and the coil S to impulse the balance or pendulum. Two opposing batteries giving an appropriate voltage may be used. The coil may be connected in series with the secondary coil of a transformer the primary coil of which is connected in series with the battery and tunnel diode. If the balance or pendulum is to be impulsed in both directions of swing two tunnel diodes are connected to the coil in a push-pull circuit. In another example, Fig. 6, the coil S is connected with the battery B and the tunnel diode T in the emittercollector circuit of a transistor V and a switching coil S is connected to the transistor base for switching the transistor to its conductive condition through an R-C time delay.

Title: Improved process for suppressing the higher harmonic currents in the secondary circuits of transformers feeding polyphase metal vapour rectifiers
IPC: H02M7/06
Filed: 1921-03-31
Abstract: 160,833. Akt.-Ges. Brown, Boveri, et Cie. April 1, 1920, [Convention date]. Vapour apparaitus, arrangements of; polyphase transformers. - In order to suppress upper harmonic currents in the secondary circuits of transformers feeding polyphase metal-vapour rectifiers, auxiliary apparatus is provided in which the secondary currents are interlinked with the primary currents in such a manner that a magnetic field is produced which tends to choke off the upper harmonic currents without affecting the currents of fundamental frequency. In the arrangement shown, the auxiliary apparatus consists of transformers T1, T2' T3, on each of which is mounted a pair of coils U1, V1 - - U3, V3 energized by the currents of secondary phases with a relative phase displacement of 180‹. The star-connected primary windings A, B, C of the main transformer T are connected to the net I, II, III through windings W1, W2, W3 on the auxiliary transformers. The magneto-motive forces developed in the auxiliary transformers by the secondary currents of the fundamental frequency, so that the magnetic fields actually developed in the auxiliary transformers are those of the upper harmonic currents, which are consequently choked off by their own fields. In a modification, the primary windings of the main transformer are connected in delta, and each auxiliary transformer carries, in addition to the two coils fed by secondary phases displaced by 180‹, two further coils connected between the ends of the corresponding primary phase and the net.

Abstract: 399,513. Boots&c. BRITISH UNITED SHOE MACHINERY CO., Ltd., Belgrave Road, Leicester.-(United Shoe Machinery Corporation ; Paterson, New Jersey, U.S.A.) April 6, 1932, No. 9842. [Class 17 (ii).] Connecting uppers to insoles and soles ; waists and shanks of soles ; shank stiffeners.- The projecting marginal edges of a shoe sole at the shank are caused to lie close against the sides of the upper by acting upon the sole, e.g. by deforming or weakening it, before the margin is urged towards the upper so that it is able to expand widthwise. For example, an abnormal outward bulge X, Fig. 7, may be produced in the shank of the sole D and this is supported in a manner to resist a limited amount of pressure, e.g. by a shank piece 20 adapted to be collapsed and materially reduced in thickness under pressure, so that as the bulge is depressed the sole is widened and the shank of the sole is urged close against the upper and remains there. Various constructions of shank piece are described. Alternatively, the sole may be weakened in the shank by splitting a tongue 80 therein, as shown in Fig. 18, or by grooving it throughout a substantial part of its width and thickness, or by forming slits therein so that it is able to expand widthwise.

Patent ID-19101-A (ID)
Inventor: GRENIER MAURICE
IPC: F25J1/00
Filed: 1997-07-07
Abstract: The method involves compressing a coolant mixture in a pre-final stage (1A) through a series of stages of a compression unit (1). The mixture is condensed partially by cooling, and then is separated to produce a vapour fraction and a liquid fraction. The vapour fraction is cooled and partially condensed, and then passed through a final compression stage (1C) to obtain a high-pressure vapour. Part of the high-pressure vapour fraction and liquid fraction is then cooled, expanded and circulated through a first heat exchanger (5). During the vapour fraction's cooling and partial condensation stage, the vapour fraction obtained from the separation of the condensed mixture is cooled by passing it through a second heat exchanger (18) with the coolant. The condensed mixture is separated in a first separator (14). The vapour fraction from it is condensed in the second heat exchanger, and then passed through a second separator (15) to produce a vapour and a liquid fraction. The vapour fraction is sent to the final compression stage, and the liquid fraction to the first heat exchanger.

Title: Composite magnetic developer
Inventor: MIYAGAWA NOBUHIRO
IPC: G03G9/08
Filed: 1979-01-11
Abstract: PURPOSE: To enable the formation of the distinct transfer images of high density on plain paper by using the composite magnetic developer which comprises evenly incorporating plural kinds of magnetic developers whose differences in dielectric constant (ε) are within the specific range and which has the specific volume resistance value and electrostatic capacity.  
     CONSTITUTION: Plural kinds of developers are so selected that the differences in the dielectric constants (ε) measured under the conditions of inter-electrode distance 0.65mm, electrode sectional area 1.43cm 2 , and inter-electrode load 105g/cm 2  become 0.2W0.8. Each developer has the specific volume resistance of 5×10 13 Ω-cm or more when measured under the same conditions as for the ε measurement and has the specific volume resistance of 1×10 14 Ω-cm or more in the form of the evenly mixed composite developer. In addition, the developer which is so formulated as to have the electrostatic capacity of 7.8W15 picofarad in the form of the composite developer when measured in the manner similar to that for ε is used. In this way, the change in the composition and the degradation or the like in the density of the images are made difficult to occur despite the long-time continuation of development.
