Title: Method and apparatus for cartographically tracing the geographical path of a vehicle moving in a fluid medium
IPC: G01C21/22
Filed: 1935-12-20
Abstract: 458,214. Intermittent toothed gearing. SUFFIT, R. M. R. C., 47, Rue Lafontaine, and TAILLEFERRE, H. E., 350, Rue Saint HonorÚ, both in Paris. Dec. 20, 1935, No. 35379. [Class 80 (i)] [See also Group XX] In a course-recording apparatus mechanism F, Fig. 5, is provided for connecting a shaft 26b to a continuously driven shaft 30 for a fraction of each of the latter's revolutions dependent on the setting of a shaft 37. A speed cam 31 and course cam 33 determine the setting of the shaft 37 in accordance with a component v sin ° of the craft's speed. A pinion 80, Fig. 6a, on the shaft 30 constantly meshes with a pinion 81 mounted in a support 83. The latter turns freely about the shaft 30 but is urged by a spring 86 to a position in which pinions 84, 85 fixed to pinion 81 mesh with pinions 77, 78. The pinion 77 and a disc 69 notched at 70 are fixed on the shaft 37 and the pinion 78 is freely mounted on the shaft 37 and in mesh with a pinion 79 on the shaft 26b. In the position shown in Fig. 6a, the pinions 84, 85 and 77, 78 are held out of mesh by the engagement with an arm 88 on the support 83 of a finger 76 on the branch 75 of a spring-urged pawl 71 resting in the notch 70. As the shaft 30 and a cam 89 having an outline comprising two semicircular parts of different diameters turn a shoulder of the cam rocks a lever 90 which is pivoted at the pivot 72 of the pawl 71 and when rocked engages a finger 93 on the branch 75 causing the pawl 71 to be withdrawn from the notch 70, the support 83 being held in the disengaged position, however, by the simultaneous engagement of the lever 90 with a finger 94 thereon. When the pawl is withdrawn from the notch 70 the disc 69, pinion 77, and shaft 37 are turned by the springs 96, Fig. 5, through an angle proportional to the component v sin ° of the craft's speed. When the cam 89 has turned sufficiently to permit the lever 90 to engage the lower cam surface again, the support 83 is released and the pinions 84, 85 engage and drive the pinions 77, 78 until the notch 70 is returned to the zero position and allows the pawl 71 to move and cause the pinions 84, 85 and 77, 78 to disengage. During the return movement of the notch 70, the pinions 78 and 79 communicate the required drive to the shaft 26b. When sin ° is negative, a cam 97 geared to the course cam 33 engages a finger 98 on the support 83 and holds the latter permanently in the disengaged position whilst a duplicate mechanism drives the shaft 26b with the interposition of a reversing gear 99. Since the mechanism F only engages and drives the shaft 26b during one half of each revolution of the shaft 30 a similar mechanism G for supplying the correction corresponding to the component of the wind speed may engage and drive the shaft 26b during the other half.

Abstract: 1,071,764. Propelling and controlling aircraft. G. WATT (C.H. GRANT). Aug.31, 1964, No.35627/64. Headings B7G and B7W. In an aircraft in which the lift of a wing is varied by directing the efflux from a gas-turbine engine over at least one surface of the wing, an engine 11 is mounted by supports 12 from the leading edge of an aerofoil 10, formed at its trailing edge with a pivoted flap and/or aileron 23. The exhaust nozzle 14 of the engine opens into the throat of an annular shroud 18, formed at its trailing edges with hinged flaps 26, whereby the jet efflux may be directed to flow in contact with the upper surface of the wing, thereby accelerating the air-flow and increasing the lift, or directing it to flow upwardly away from the wing thereby reducing lift. The engine acts as an ejector pump by drawing air through the annular space between shroud 18 and engine 11 and further air may be drawn through a slot 33 between the rear end of shroud 18 and the leading edge of aerofoil 10. In an alternative embodiment Fig.3, (not shown), the axis of the engine is below the chord of the aerofoil, which is formed with a slot (46) extending rearwardly from the lower to the upper surface and opening from the throat of a shroud (43), a pivoted flap (48) being adjustable to allow a gas flow through slot (46) and over the rear upper surface of the aerofoil, or directly through shroud (43) to flow over the rear lower surface.

Title: Utilization of inorganic acids in the preparation of fluid lubricants
IPC: F02B3/06
Filed: 1956-11-23
Abstract: A fluid lubricating composition, suitable for use in automotive transmissions and marine diesel upper cylinders, comprises a major proportion of a lubricating oil together with a neutralized blend of an inorganic acid, a C1-C3 carboxylic acid and a C7-C10 carboxylic acid.  The lubricating oil may be a mineral oil or a synthetic oil or a mixture of these.  Synthetic lubricating oils mentioned are esters of monobasic acids (e.g. an ester of C8 oxo alcohol with C8 oxo acid, or an ester of C13 oxo alcohol with octanoic acid), esters of dibasic acids (e.g. di-2-ethyl-hexyl sebacate or di-nonyl adipate), esters of glycols (e.g. C13 oxo acid diester of tetraethyleneglycol), complex esters, esters of phosphoric acid (e.g. the ester formed by contacting 3 mols. of the mono-methyl ester of ethylene glycol with 1 mol. of phosphorus oxychloride), halocarbon oils (e.g. chlorotrifluoroethylene polymer), polysiloxanes, sulphite esters, carbonate esters, mercaptals, formals and polyglycols (e.g. the compounds formed by condensing butyl alcohol with 14 units of propylene oxide).  The inorganic acid may be sulphuric, hydrochloric, phosphoric or nitric acid. Instead of sulphuric acid, an acid sludge containing sulphuric acid (e.g. a sludge resulting from the treatment of petroleum distillate with oleum) may be employed.  Suitable C1-C3 acids are formic, acetic, propionic, chloro-acetic, glycollic and thioglycollic acids and glycine. C7-C10 acids specified are 5-methyl-2-hexanoic, heptanoic, octanoic, 2-ethyl-hexanoic, nonanoic and decanoic acids and C8 or C10 oxo acids.  The blend of acids may be neutralized with a metal base (e.g. the hydroxide or carbonate of calcium, barium, strontium or magnesium).  The lubricating composition may also contain additional ingredients such as oxidation inhibitors (e.g. phenyl alpha naphthylamine), corrosion inhibitors (e.g. sorbitan mono-oleate) and tackiness agents (e.g. polybutene). In the examples, greases are prepared from mineral lubricating oil, sulphuric acid (or sulphuric acid sludge or nitric acid), acetic acid, commercial capric acid (containing also caprylic and lauric acids), hydrated lime and phenyl alpha naphthylamine.  The greases are then diluted with further mineral lubricating oil to produce the final fluid lubricating compositions.  The effect of omitting the inorganic acid is described.

Abstract: 1486772 Television; cathode-ray tube circuits INDEPENDENT BROADCASTING AUTHORITY 29 July 1974 [30 July 1973] 36206/73 Headings H4F and H4T Apparatus associated with a television receiver 11 for displaying, on the receiver screen, instead of, or additional to, the television picture, matrix or alphanumeric characters transmitted, in coded form, during one or two line periods in each field blanking period of a television signal, includes in a text signal generator a store (Fig. 3, not shown) which stores, under the control of a data receiver, a selected part of the received information which is then repeatedly read from the store and supplied to a character generator which produces signals to reproduce matrix or alphanumeric characters in a 7 Î 5 matrix which are fed to a video switch 3 and a text adder, whose output is connected to another input of video switch 3. Selection of input 1 to video switch 3 causes a conventional television display, selection of input 3 causes a display of only the matrix of alphanumeric characters; selection of input 2 causes display of both the television picture and the characters, whereas selection of both inputs 1 and 3 causes the display of both the television picture and the characters depending on which signal is instantaneously greater. The display may be in blaok-and-white or colour. The received signals may be as described in Specification 1,486,771 in which each "1" bit is represented by "10" and each "0" bit is represented by "01", each line period including a run-in, synchronizing, signal, a start code, and address signals, followed by the codes for 10 alphanumeric symbols. The transmitted data may represent 50 "pages", the information relating to only one page being stored in the store in the text signal generator. The data receiver includes two data registers, which store respectively the first and second digits of each "10" and "01" code; if the contents of the registers for any alphanumeric character are not complementary a blank is displayed. The apparatus may receive from, and return to, the television receiver 11 a modulated or demodulated signal. A second television demodulator may be ineluded so that characters received on one television channel may be displayed on the television picture received on a different television channel; alternatively the characters may be received independently of any video signal, for example over a cable network.  The character signals generated in the character generator in a 7 x 5 matrix form may have added to them rounding bit signals in a 6 x 4 matrix form, superimposed in a staggered arrangement, Fig. 5A. The character signals and rounding bit signals may be derived from respective read only memories addressed in an out of step fashion.

Title: Change-over device for automatic switching over from star to delta connections and vice versa depending upon load in electric motors
IPC: H02P1/32
Filed: 1960-10-21
Abstract: 925,238. Control of A.C. motors. U. BARERA, and R. ROSSO. Oct. 21, 1960 [Oct. 31, 1959], No. 36254/60. Class 38 (3). The windings 1 of a squirrelcage induction motor are automatically connected in star for starting, and thereafter in delta or star according to the load by separate contactors 7 and 8 fed from a step-down transformer 5, a stabilizing device sensitive to the load preventing too frequent changes from delta due to transient load changes. Operation of start button 6 energizes main contactor coil 4 and hence coil 12 to close star contactor 8; a high current relay 14 and a low current one 13 are now in series with each other and with one phase of the motor. " Make " contacts 16 on relay 14 maintain the star contactor closed until the motor current drops below a predetermined level. If it drops to a very low value, e.g. the motor running light, both 13 and 14 are released and star connection is held through reclosure of contacts 15. Otherwise, relay 14 only is released, de-energizing the star contactor and allowing delta-contactor coil 11 to be energized through interlock contacts 19. Delayed-action change-over contacts 23 in this coil circuit now move from a " close delta " to a " close star " position but the delta contactor is maintained closed through contacts 20. These latter are closed by a relay having a winding 21 in series with the motor and a second winding 22 fed from the transformer 5. The circuit of winding 22 is periodically broken by a pulsing thermal switch 26, 27, the element 24 of which is in series with the motor. If the motor current transiently drops below the rating of the winding 21, current through 22 holds the contacts 20 closed ; if the drop persists until the thermal switch opens the relay is released and winding 11 is de-energized, opening delta contactor 7 and allowing the star contactor 8 to close through interlock contacts 17. Relay windings 13 and 14 are again in series with the motor and if the current rises again to surpass the rating of the former (but is not as high as the starting surge which energizes 14) the contacts 15 open to initiate the change back to delta.  If the motor runs at or near full load steadily in delta the pulsing thermal switch element 24 is short-circuited by contacts 30 on a thermal switch 29 in all phases of the motor circuit.
