Title: An automatically controlled carburettor for internal combustion engines
IPC: F02M9/08
Filed: 1932-10-31
Abstract: 396,586. Spray carburetters. BEY, O. F., 336, Rue de Vaugirard, Paris. Oct. 31, 1932, No. 30656. Convention date, Nov. 13, 1931. [Class 7 (iii).]. In a carburetter for internal-combustion engines for propelling vehicles and having a float chamber communicating with a reserve fuel chamber into which dip the lower ends of fuel nozzles, the reserve chamber providing an excess of fuel during acceleration, and the carburetter being so disposed in the vehicle that the fuel nozzles, which are arranged in line, are parallel to the longitudinal axis of the vehicle, the reserve fuel chamber is disposed at the rear of the float chamber so as to cause the petrol level in the reserve chamber to rise when the vehicle is climbing or ascending hills and to fall when it is descending or travelling down them. A wide passage 4 feeds fuel from a float chamber 1 to a well 5 leading into an auxiliary reservoir 8 into which dip the bases of three fuel nozzles 10, 14, 15. A slotted or perforated sleeve 6 surrounds the base 16 of the nozzle 14 which, when a throttle valve 24 has been turned clockwise from the position shown to cut off connection between the induction passage 25 and the nozzles 10, 14, sprays fuel into a passage 22 receiving air through a port 20. Anticlockwise rotation of the valve 24 then uncovers a similar passage 23 about the auxiliary nozzle 15 permitting both nozzles to supply the engine. Further rotation uncovers the main nozzle 10 and finally cuts off the nozzles 14, 15 leaving the nozzle 10 to function alone. By this time, the nozzles 14, 15 have been emptied of fuel and air is sucked into the chambers 22, 23, through the nozzles 14, 15, emulsifying the fuel in the reservoir 8. Additional fuel may be supplied to the nozzle 10 through a port adapted to be closed by a thermostatically operated valve 28 when the engine has become warm. The three nozzles are arranged in line and parallel to the longitudinal axis of the vehicle, the fuel which normally keeps the level A A taking up a level B B, with increased depth in the reservoir 8, when hills are ascended and a level C C, with reduced depth therein, on descending them.

A motor road vehicle of the type in which the driver's cab is at the extreme forward end of the vehicle and the upper end of the substantially flat front wall of the cab is provided with the usual windscreen, a safety mirror is mounted externally of and across or partly across the top of the windscreen and comprises one or more downwardly'facing reflectors adapted to afford to the driver looking through-the upper portion of the windscreen, a directly-reflected image of the road surface which is immediately in front of the vehicle and at least across the full width of the vehicle. As shown, a mirror 14 is carried in a metal holder 17 provided with trunnions 21 engaged in bayonet slots 22 in end panels 20 of a cowl 19 secured to the front wall 12 of the vehicle. The trunnions are screw-threaded and carry such a lock-nut 23, whereby the mirror may be retained in various angular positions. The mirror may be curved longitudinally or may be of shallow inverted V-shape to increase the range of vision.
Patent GB-1165057-A (GB)
Title: Compression Testing Method.
IPC: F02P17/00
Filed: 1967-07-05
Abstract: 1,165,057. Measuring engine compression electrically. MOBIL OIL CORP. July 5, 1967 [July 5, 1966], No.30973/67. Heading G1N. To measure the compression in respective cylinders of an internal combustion engine, an electrical starter motor is used to drive the engine while combustion is prevented by, for example, reducing a variable resistor 10, Fig. 2, in the ignition coil circuit, and the variations in the loading of the motor supply, or in the speed variations of the engine, are displayed as a function of time. A battery (1, Fig. 1, not shown), supplying the starter motor (not shown), is connected by way of a potential divider (5,5') to a sensitive meter 2, in opposition to a reference voltage source (7,8), the meter (2) indicating variations in battery voltage. A switch shorts out one resistor (5) of the divider if a 6v battery is used instead of a 12v. The battery current alternatively may be measured. The meter (2) prefereably forms part of a recording system in which the load variations are plotted (16, Fig. 4A, and 18, Fig. 4B, not shown) simultaneously with reference pulses (17, 20) derived from the distributor to identify the cylinders. To obtain the reference pulses, one of the distributer outputs 13, Fig. 2, is connected to a second meter 15, the resistor 10 being set to prevent the plug 14 from firing but to allow sufficient voltage to pass from the rotor arm 11 to the contact 13 to operate the meter. Alternatively, the ignition coil secondary winding may be connected to one of the distributor outputs (13, Fig. 3, not shown) and the meter (15) operated from the rotor arm. If the speed of the engine is to be monitored instead of battery loading, a pulse producing transducer is used in association with an engine driven gear which has one tooth filed down to cause the transducer to produce one pulse per revolution of the gear.

Abstract: 484,498. Vehicle spring - suspensions. CLEMENTS, W. A. Nov. 13, 1936, Nos. 31121 and 34101. [Class 108 (ii)] In a vehicle spring-suspension of the kind in which the leverage of a spring or springs acting between the chassis and a pivoted support increases with the load, helical springs 14, 15 having an elongation 36 extending at an acute angle to the supporting and supported surfaces are employed and are adjusted longitudinally of the vehicle by screw-andnut mechanism. As shown the springs 14, 15 are secured at one end to a transverse shaft 38 carried by a pair of longitudinal members 40, 41, between which and longitudinal frame members 48, 49 are interposed rollers 52. At their free ends the springs are connected to an anti-friction roller 46 abutting against the support 24, the latter being flexibly hinged to a shaft 20 by means of pins 28 engaging a hinge member 32 containing a rubber block 34. Adjustment of the shaft 38 is effected by means of a rotatable threaded rod 56 engaging internally threaded blocks 60, 61 which are slidable along the frame members 48, 49. The rod 56 is rotated in one direction or the other by one-way clutches mounted on the ends of lever arms 68, 69, which are actuated by the vibrations of the support or plate 24, the latter engaging with lost motion stops 74, 75 on vertical rods 70, 71 universally jointed to the arms 68, 69. Under heavy loads the springs 14, 15 are displaced with the shaft 38 away from the fulcrum 20, while under light loads they are moved towards the fulcrum. Additional springs 86 are arranged to come into operation only under excessive loads. Modifications are described in which the springs 14, 15 are used in combination with main leaf springs.

Magnesium oxide is deposited by a similar process to give the same density of coated surface. The electrode is assembled in the valve, degassed and activated by heating to 700-900‹C for a few minutes. Alternatively thin films of barium and magnesium are evaporated on to the support and oxidized by exposure to oxygen; or a mixture of the carbonates of barium and strontium is sprayed on to a thickness of 5 x 10-4 inches followed by magnesium oxide to the same thickness.
