Title: Improvements in rangefinders
IPC: G01C3/00
Filed: 1932-12-23
Abstract: 394,255. Range finders.SOC. D'OPTIQUE ET DE MECANIQUE DE HAUTE PRECISION, 125, Boulevard Davout, Paris. Dec. 23, 1932, No. 36526. Convention date, Jan. 14. [Class 97 (i).] In a rangefinder mounted for rotation about a horizontal axis so that it can be made to follow a moving elevated target, and having a measuring deflecting system moved by an adjustment head which is rotated proportionally to the reciprocal of the range, an additional movement is imparted to the deflecting system independently of that produced by the adjustment head, this additional movement being effected by rotation of the instrument in elevation, and being of such magnitude that, once a range measurement has been made, the deflecting system is automatically moved in accordance with the variations of range, without further rotation of the adjustment head, so long as the target remains at a constant height. The two movements of the deflecting system are combined by means of a differential gear. The range-finder tube A is rotatably mounted in bearings B on a fixed support C, and contains a tube E in which the deflecting prism I is carried by a rack a. A pinion e gearing with the rack is secured to a spindle f passing loosely through a member L, which is secured to the adjustment head M and carries a spindle g on which is mounted a bevel wheel h gearing with a wheel j secured to the spindle f. The wheel h also gears with a bevel wheel i which is loose on the spindle f and is integral with a worm-wheel k adapted to be rotated when the range-finder is turned in its bearings B. A worm N, Fig. 3, gearing with the wheel k is connected to a shaft l terminating in a friction disc O driven by a friction wheel P. The disc O is moved across the wheel P in accordance with the determined range and the wheel P is rotated by the means which effects the rotation of the instrument in its bearing B. To effect the displacement of the disc O, a bevel wheel S secured to the spindle f gears with a bevel wheel p, the rotation of which is transmitted to a screw q engaging in a nut t having an extension passing between shoulders u on the shaft l. The hand-wheel V, Fig. 2, for rotating the instrument in its bearing B rotates a bevel wheel T gearing with a bevel wheel Q secured to the wheel P, and also rotates a toothed wheel W gearing with a wheel X on the shaft of a worm v driving a worm wheel Y. The wheel Y is connected by gearing x, y of the form shown in Fig. 4, to a bevel wheel Z gearing with a fixed ring z so that rotation of the wheel causes it to roll round the ring to produce the movement of the range-finder in its bearing B. The gearing x, y ensures the correct relationship between the angular movement of the instrument and the rotation of the friction wheel P, Specification 263,437, [Class 97 (i), Optical systems &c.], is referred to.

Title: Improvements in carburation devices of the overflow type for internal combustion engines
Inventor: MENNESSON ANDRE LOUIS
IPC: F02M17/06
Filed: 1954-12-21
Abstract: 760,468. Carburetters. SOLEX. Dec. 21, 1954 [Dec. 24, 1953]. No. 36932/54. Class 7 (3). In a carburetter of the overflow type in which fuel is sucked into the engine from an overflow chamber to which fuel is fed from a pump and where a fuel constant level is fixed by an overflow weir from which the excess of fuel drops into a low level chamber the carburetter being advantageously provided with distributing means for connecting the suction side of the pump either with the bottom of the low level chamber or with a fuel tank or with both according to the amount of fuel present in the low level chamber the top portion of the overflow chamber is connected exclusively with the top portion of the low level chamber which in turn is connected with the main air intake of the carburetter whereby on the one hand the same pressure exists in these two portions of the chambers and on the other hand the fuel vapours which are evolved under some conditions in the overflow chamber are conveyed toward the low level chamber instead of flowing directly to the main air intake of the carburetter as was the case when the top portion of the overflow chamber was in direct communication with the main air intake. Fuel is fed by a pump 7 into an overflow chamber 5 in which the fuel is maintained at a level N-N by means of an overflow tube 10 through which fuel' flows to a low level chamber 16 through a tube 18. A float operated valve 21, 22 is provided to connect the suction side of the pump either with the bottom of the low level chamber or with a fuel tank 19 or with both. The top portion of the overflow chamber is connected with the top portion of the low level chamber either by means of the tube 18 or by a separate tube. The tube 18 is of a section sufficient to be sure that even at the maximum fuel flow rate air can flow freely through the conduit 18. It is advantageous thermally to insulate the chamber 16 from the hot portions of the carburation device. For instance under the hood of an automobile vehicle chamber 16 can be located at a point where it is always suitably cooled down by air circulation. When the pump 7 ceases to feed fuel due to stopping of the engine the level in the chamber 5 drops due to the presence of a small orifice 27. This orifice might be replaced by a thin vertical slot or by a plurality of holes. When the engine is stopped when it is very hot vapour bubbles of fuel are formed in particular in the chamber 5. These vapour bubbles when flowing out carry fuel along with them. It has been found that the level N-N can be fixed sufficiently low to prevent this vapour bubble trouble while being sufficiently high to permit of starting the engine even if the pump 7 does not instantaneously feed fuel. An air filter may be provided on the intake 2.

Apparatus for making a record of an electrical quantity in the form of a higher order digit or number and an adjacent lower order digit comprises a potentiometer 11 controlled by a servo system 10 that is mechanically connected to the moving arm 23 and to a hundreds and tens print drum 46 attached to a wheel 47 with a notch 50 for each position 49 adapted to co-operate with a pawl 54; a solenoid 55 responsive to a print command switch 56 for bringing the pawl 54 to a position in which it can engage a notch and a switch 94 for applying a signal to the servo system so as to move the drum 46 until the pawl 54 engages a notch 50 whilst simultaneously moving a units sector 72 in correspondence with this movement of the drum 46. With the switch 28 in the position shown the servo system positions the drum 46 in accordance with a variable applied to the terminals 14,15. When switch 56 is closed, switch 28 shorts half the control winding of the shaded pole type motor 10 which turns the drum 46 back till a number 49 reaches the printing position and the pawl 54 locks it there, stalling the motor 10. Closing switch 56 also operates clutch 63 to couple the drive to sector 72. After a sufficient delay controlled by circuit 102, a pawl 75 locks the sector 72 through teeth 74 on disc 73 and print hammers 86, 87 cause an impression to be made on record sheet 90. The constant speed drive to sheet 90 may be used to control the print command switch 56 if records are required at regular intervals of time. If a graphical record is also required the movement of the drum 46 may be transmitted to a pen 171,Fig.3, carried by a block 172. An alternative mechanical transmission between drum 46 and sector 72 is described, Fig. 2 (not shown).
