A camera with a built-in exposure meter has a lever 6 set by a stop 4 on a film cartridge 3 the stop being positioned in accordance with film sensitivity so as to rotate a galvanometer 11 into a position related to such sensitivity. The galvanometer 11 is connected to a photo-sensitive device, not shown, and has an indicator 12 co-operating with an exposure value scale 13. A shutter speed and diaphragm aperture setting rings 15 and 16 are rotatable on a tube 2 having a scale 18. The ring 15 has a pointer 17, while ring 16 has a pointer 20 co-operating with an exposure value scale 19. The ring 16 is rotated for correct exposure until pointer 20 coincides with the same exposure value as shown by indicator 13. Alternatively, lever 6 may adjust a resistance in the measuring circuit, or an adjustable shutter in front of the photo-sensitive device to compensate for film sensitivity.

Abstract: 350,662. Hydraulic transmission of power. WATERBURY TOOL CO., East Aurora Street, Waterbury, Connecticut, U.S.A. April 25, 1930, No. 12764. Convention date. May 8,1929.

Title: Improvements in and relating to fluid pressure indicating, measuring, recording, controlling or regulating apparatus
IPC: G01R17/08
Filed: 1943-08-09
Abstract: 582,094. Regulating combustion. LINDARS, H. Aug. 9, 1943, No. 12847. [Class 51 (i)] [Also in Group XXXVIII] In apparatus for controlling fuel feed to a furnace in proportion to the draught, pressure difference caused by the draught across an orifice causes a lever to be displaced from its equilibrium position, so actuating a reversible electric motor, which restores its equilibrium by moving the point of application of a weight upon the lever, such movement changing the speed of an electric motor which effects the fuel feed. Fig. 2 shows a fuel/air ratio controller for a furnace. Air supplied to the retort 72 by the fan 75 sets up across the orifice 77 a difference in pressure which is applied to a diaphragm in the chamber 30 via pipes 78, 79. Movement of the diaphragm is applied via the stem 29 to the bell-crank 25. The lever 48, counterbalanced by the weight 50, has its pivot 47 mounted on a nut 45 movable laterally by the rotation of the threaded spindle 42 driven by the reversible electric motor 53 through the coupling 53a, 53b and clutch 53c. Roller 49 mounted on the lever 48 is normally positioned over the fulcrum 26 of the bell-crank 25. The lever 64 weighted at 67 and pivoted at a point 65 vertically above the fulcrum 26, applies pressure to the lever 48 through the roller 66 normally positioned vertically above the fulcrum 47. Movement of the bell-crank 25 in response to change of pressure difference in the chamber 30, causes contact assemblies 32, 34 and 38, 40, or 33, 35 and 39, 41 to operate relays, Fig. 3 (not shown), to cause the motor 53 to move the lever 48 laterally in such a direction that the pressure applied through the roller 66, the lever 48 and its roller 49 restores the bell-crank 25 to equilibrium. The lever arrangement ensures that the torque applied to the bell-crank 25 is proportional to the square of the distance (indicated by the pointer 85) moved by the pivot 47. The air flow being proportional to the square of the pressure difference, the distance moved by the pivot 47 is proportional to the air flow. Rotation of the spindle 42 also operates the disc 84 controlling a rheostat for the fuel feed motor 80, so that fuel proportional to the air flow is supplied. In a modification, Fig. I (not shown), a single lever having an electric motor mounted on it, moves a weight along the lever to balance pressure applied to it from bellows. A further modification, Fig. 4 (not shown), obtains the differential pressure effect by means of two bellows acting on the same lever, and also uses a similar arrangement to maintain a given pressure ratio-

Title: Electron beam deflection speed-up circuit
IPC: G09G1/04
Filed: 1967-03-21
Abstract: 1,135,918. Cathode - ray tube circuits. SPERRY RAND CORP. 21 March, 1967 [1 April, 1966], No. 13238/67. Heading H4T. The beam of a cathode-ray tube is deflected at a first rate in equal incremental steps and at a second, increased, rate when steps of an increased magnitude are required. The invention is concerned with a system in which the equal incremental step deflections are utilized during the painting of characters and the increased magnitude steps when it is desired to move the beam suddenly some distance across the screen to trace vectors or maps. Fig. 1 (which relates to the horizontal deflection, a similar arrangement being employed for vertical deflection) shows an embodiment utilizing a single ended deflection winding 1-14 through which equal incremental current steps are caused to flow from a voltage source 1-16 to earth via a Darlington circuit 1-12 controlled by the horizontal deflection amplifier 1-2, the emitter of which is connected to a five stage counter 1-4 so that thirty-two cyclic step variations are produced. During this operation the difference between the 15V supply at terminal 1-16 and the back e.m.f. across winding 1-14 (i.e. at point 1-24) is greater than the 10V supply at terminal 1-26 so that diode 1-32 is backbiased. When, however, the beam is to be moved suddenly to a new position requiring a large step variation (e.g. all of the counter stages may be set simultaneously) the difference between the 15V supply and the back e.m.f. falls below the 10V potential at terminal 1-26 so that diode 1-32 conducts momentarily producing a pulse which, via the secondary of transformer 1-28 switches on transistor 1-34 to connect the much higher (60V) potential at terminal 1-36 to the deflection winding which results in an extremely high rate of change of current and thus in a much faster movement of the beam. At the end of the normal cycle of counter 1-4 a fly-back voltage pulse of opposite polarity is developed across the winding 1-14 and speeds up the rate at which the beam is returned to the other side of the screen. With the single-ended deflection system an additional deflection winding is required to position the beam initially at the (e.g. left-hand) side of the screen. Fig. 3 shows a push-pull deflection arrangement in which circuitry 3-34 operating in similar manner to the circuit of Fig. 1 is employed to speed-up the fly-back time by increasing the rate at which the current in winding 3-14 increases when due to the transformer action between this winding and winding 3-32 the voltage induced in 3-14 when the current flow in winding 3-22 attempts to cease also attempts to stop the current flow in winding 3-14. By connecting a second circuit similar to 3-34 across deflection winding 3-32 a speed up of the beam movement during the trace period may also be produced as described in connection with Fig. 1.
