Abstract: 100,924. Stratton, F. F. Jan. 13, 1916. Spray carburettors.-A number of fuel nozzles are brought into action in succession by caps suspended from a suction-actuated air-controlling valve of the kind described in Specification 8492/14. The valve, of two diameters E<1>, E slides in the carburettor body A, B and carries caps J, K, &c., which are of different lengths and fit loosely over, and bring into action in succession, the nozzles J<1>, K<1>, &c. A central uncontrolled pilot nozzle L is situated in a choke-tube L<3> of considerable length, the other nozzles being situated in chambers formed by partitions M<2> &c. radiating from the choke-tube L<3>, the valve E<1> being slotted to pass over these partitions. The valve is prevented from rotating by strips P and, at its lower end, is provided with ports at different heights to admit air to the nozzle chambers as it rises. The body A, B is secured by bolts to the base F, through ports in which air for the pilot nozzle enters. The casing Q of the hot-air jacket is rotatable to facilitate connecting-up.

One output of the second convertor goes via a sinusoidal carrier voltage generator and also directly to a second multiplexer. A second output of this convertor also goes to the second multiplexer, which receives an output signal from the control unit. - The output of a buffer amplifier is fed through a tuner to an inductor which is also connected to the control unit. The output of the second multiplexer is fed to the modulator, and the control unit is driven by a programmable timer.

Title: Telegram retransmission system
Inventor: TASHIRO SHIYUNJI
IPC: G06F15/16
Filed: 1984-01-09
Abstract: PURPOSE:To ensure the continuous execution of processing with no loss of a telegram despite a breakdown of a host computer, by providing a memory part to a terminal device to store telegrams for transmission. CONSTITUTION:A terminal device 410 transmits a telegram to a circuit 401 via a control part 40 and at the same time adds an identification number to the transmitted telegram to store the telegram to a memory part 44. If a host computer is brokendown, the journal information is first checked. However a telegram indicating retransmission is delivered to the device 410 in case the journalizing action is not through yet. When the device 410 receives said telegram, the part 40 transmits again all telegram data stored in the part 44 to the circuit 401 for each piece. These telegrams are reprocessed in the same way as a new telegram. Thus the processing is continued with no loss of a telegram despite the breakdown of the host computer by providing the part 44 to the device 410 to preserve the transmitted telegrams.

Title: Flash photographic device
Inventor: KATAOKA HIROYUKI
IPC: G03B7/16
Filed: 1982-01-06
Abstract: PURPOSE:To perform flash photographic control so that while natural light is considered additionally, porper exposure regarding a subject and its background is obtained, by measuring even the natural light from the background of the subject when measuring the quantity of reflected light from the subject by preliminary lighting. CONSTITUTION:Once preliminary lighting starts, light from a discharge tube 7 is reflected by the subject to strike a phototransistor 23 and the output voltage of a distance measuring capacitor 57 rises according to the photocurrent of the phototransistor 23. The discharging voltage of the capacitor 57 rises according to the natural light with which the subject and its background are irradiated even after the lighting of the discharge tube 7 stops. The discharging voltage of the capacitor 57 is latched in latch circuits 85-87 as distance information by the output level inversion of a one-shot circuit about tens microseconds after the starting of the preliminary lighting. On the basis of this information, the lighting of a discharge tube 13 for photographing is controlled to output aperture controlling information to a camera side through a terminal (b).
