Abstract: 124,485. Sharman, A. W. Jan. 27, 1916. Lamp and flash signals.-The light is emitted in pulsations of such frequency that the interruptions or variations are invisible to the unaided eye. The pulsations are modified to form signal elements which can be observed in receiving apparatus which analyses the pulsations. Figs. 1 and 2 show one arrangement of apparatus. At the transmitting station, a disk A having perforations a is rotated by means of a motor D in front of a lamp B. At the receiving station a disk E similar to A is rotated synchronously with it by the motor F and a telescope G is provided for the observer. The lamp B is carried on a signalling key C and is displaced when the key is operated, thus modifying the pulsations which are observed through the telescope G. In a modified form of apparatus, the lamp is fixed and the interrupting device consists of two disks, one rotating and the other adapted to be displaced by the signalling key to modify the pulsations. To facilitate speed adjustment and phasing of the receiver, two sources of intermittent light may be provided at the transmitter, one for the adjustment and one for signalling.

Title: Improvements in or relating to carburettors
IPC: F02M3/08
Filed: 1919-01-22
Abstract: 141,443. Dicker, S. G. S., (Stromberg Motor Devices Co.). Jan. 22, 1919. Spray carburettors are provided with an annular suction-actuated supplementary air-valve seated on the Venturi tube, this valve being connected to the main air valve, to a fuel valve, and to a dashpot piston working in the fuel chamber. The carburettor is provided with two independently-operated butterfly-valves 17, 9. Supplementary air is admitted from an opening (not shown) by an annular suction-operated valve 30 normally resting on the Venturi tube 23. This valve may be weighted, but, in the form shown, is controlled by a lever, one end of which is connected to the valve 17, and the other to a dash-pot plunger 40 working in a well communicating with the float chamber. The supply of fuel to the main nozzle is controlled by a needle valve 55, Fig. 7, carried by the air valve 30, so that as this valve opens to admit more air, the fuel supply is also increased. An adjustable pilot nozzle 95, near the throttle 9, is fed from a passage 103 below the needle valve 55, and takes its air supply from the space just below the throttle. The main nozzle comprises an outer member 19, and inner tubes 70, 74 having an annular space between them opening into a small chamber 77. The tube 70 is perforated, as at 80, and has heads at each end, forming two other chambers 72, 57, comunication between which is limited by holes 73. The chambers 72, 77 are independently supplied with air through small orifices situated above the normal fuel level, the supply to the chamber 77 being controlled by a needle valve connected to the throttle 9, so that as the throttle is closed, more air is admitted to the nozzle. In the modification where the annular air valve 30 is weighted, the dash-pot 40 is combined with the needle valve 55, and a passage leads from the needle-valve chamber to the Venturi tube, so that as the air valve lifts and raises the needle valve, fuel is lifted by the plunger 40 and passes into the Venturi tube.

Abstract: 1372331 Automatic voltage control ING C OLIVETTI & C SpA 14 Jan 1972 [18 Jan 1971] 1955/72 Heading G3R [Also in Division H2] A constant voltage electric power supply unit for electronic equipment having varied output requirements has a first transformer 100 arranged to be fed from mains and a first control means 103 for keeping the voltage at output terminals 22, 23 of the transformer constant and a second transformer 101 arranged to be fed from the mains for producing at its output terminals, which are connected in parallel with the output terminals of the first transformer, the same predetermined output voltage as the first transformer and second control means 105 "subordinate" to the first control means. As shown the first transformer 4 may have three secondary windings 5, 6, 7 of which the winding 5 is connected to output terminals 22, 23, through rectifier bridge 13 fuse 16, transistor 18 and an indicating resistor 21. The conduction of the transistor 18 is controlled by a second transistor 28 responsive to the output of an amplifier which compares the voltage tapped from between resistors 29, 30 connected across terminals 22, 23 with a voltage from a tapping point 32 on a reference voltage circuit R. Undervoltage protection is provided by the transistors 37, 38 which influence the transistor 28 to cause circuit interruption by the transistor 18. Overvoltage of the terminals 22, 23, will switch on transistor 41, 42 which render a controlled diode 46 conducting so that the terminals 22, 23 are short-circuited to bring the undervoltage protection into operation. The second transformer, Fig.3 (not shown), has a similar circuit with connections to terminals 54, 55 allowing the control means thereof to cooperate with the control means of the first transformer. A further transistor control stage may be inserted between transistors 28 and 18 in each transformer output control circuit,  Figs. 4 and 5 (not shown), for greater output power.
