Title: Photographic pivoted blade shutter
IPC: G03B9/22
Filed: 1960-12-09
Abstract: 964,199. Photographic camera shutters. AGFA A.G. Dec. 9, 1960 [Dec. 11, 1959], No. 42550/60. Heading G2A. A photographic pivoted blade shutter has a blade opening and a blade closing ring and at least one retarding means for the latter to set the shutter speed and means to release both blade simultaneously so that they tend to move in the same direction, the blade closing ring being retarded in accordance with the set shutter speed so that the opening ring overruns the closing ring to open the blades, the closing ring finally overrunning the opening ring to close the blades. In the shutter device shown, the blades 5 are operated by rings 3, 4 which may be coupled by lugs 8, 12 so that they may be set, and their drive springs 11, 15, tensioned by pivoting lever 17 in direction 43 until the rings are latched by means of a shutter release lever 23, 25 engaging a notch 46. The shutter time is controlled by gear means engaging with members 26-31 or inertia mean 33- 39. When the blade rings are released they move together until ring 3 engages one of the retarding means which slows it down relative to the ring 4 so that the blades open. When ring 3 leaves the retarding means the blades close and the rings eventually come to rest with lug 12 adjacent a stop 16. The gear retarding means is used for long exposure times and comprises a lever 28 pivoted at 26 and spring 27 urged so that its pin 29 will extend in the path of a lug 10 on the blade ring 3 by an amount determined by the position of a pin 30 along a control cam 31. Movement of the lever 28 is slowed down by gearing. The inertia retarding means operates in a similar way but without the gearing and therefore gives faster exposure times. The moment of inertia of the lever 34, a pin 36 on which engages a projection 9 on the ring 3 is varied by bending a lug 39 thereon relative to its pivoting pin 33. The range of diaphragm apertures which may be chosen is varied by means of a pin 42 on the diaphragm aperture setting means engaging a flange 40 on the exposure control cam 32. This shutter may be used with an ever set camera in which case lever 23, 25 is omitted.

Filed: 1967-08-16
Abstract: 1,216,094. Reciprocating pumps. C. A. V. Ltd. Aug.13, 1968 [Aug.16, 1967; Sept.25, 1967], Nos. 37693/67 and 43489/67. Heading F1A. In a fuel injection pump having a feed pump 25 supplying an injection cylinder 11 via a governor controlled metering valve 33, the amount of fuel delivered to the cylinder 11 is regulated by the valve 33, and injection timing controlled by a fuel operated piston 39. Fuel enters one end of a shuttle cylinder via passages 27 and 34, and a valve 23 and causes the shuttle 19 to expel fuel from the other end of the cylinder via valve 20, and passage 18 into the cylinder 11 during the filling stroke. On injection fuel is pumped into the outlet ports 15 via passages 16 and 14; at the same time the valves 20, 22, 23 and 24 in the distributer 10 rotate and fuel enters the other end of the shuttle cylinder via the valve 33 and passage 21. The metering valve comprises an axially movable member 41, having a central bore 46 open at one end, in a sleeve 40; the open end of the bore being closed by a valve element 52 pressed against the opening by springs 53 and 54, governor weights are positioned at the other end of the member 41. The bore 46 is open to a groove 47 on the member, and a passage 36, and is in restricted communication with a groove 48 and passage 27 by way of an orifice 49. The groove 48 is in variable communication with the passage 21, the degree of registration being determined by the forces of the governor weights and springs; such forces balance at constant speed but move the member axially on a change in speed. The fuel entering the shuttle cylinder by way of passage 21, and thus the amount delivered to the cylinder 11, is regulated by an extension of the shuttle co-operating with a cam surface 34a a piston 35 which is moved against the action of a spring by fuel pressure supplied via passage 36. The same pressure is used to operate a piston 37 attached to the cam ring 13, movement of which causes rotation of the cam ring to vary the timing. In another embodiment Fig. 2 (not shown), a valve element is positioned at the other end of the member and a further groove on the member is in open to a central bore; this groove communicates with a part leading to a drain by way of an orifice. Between the port and orific a passage leads to a piston device similar to the piston 39.

Abstract: 1487762 Automatic gain control SGS-ATES COMPONENTI ELETTRONICI SpA 18 Oct 1974 [19 Oct 1973] 45286/74 Heading H4R In a variable impedance for connection at an amplifier input and controlled by the amplifier output signal to keep the output level substantially constant, the impedance comprises two groups of transistors having their base emitter junctions in series with respect to the D.C. control current applied to control the impedance, each group comprising two or more transistors and the two groups being in parallel opposed relation relative the A.C. signal applied to the impedance. As described the amplifier output signal is applied at O, Fig. 2, to be rectified and provide a control signal at A to control the base emitter currents of transistors Q1 to Q4 and therefore the impedance that they present to the signal at point I. The impedance presented to the control potential at A by the base of transistor Q1 is high since the transistors have high current gain, and the high gain means that the pair Q1 and Q2 operates under very similar conditions to the pair Q3 and Q4 providing a balanced loading on the signal at I and therefore low distortion, while the use of pairs of transistors reduces the signal voltage across each base emitter junction. The transistors are produced in monolithic integrated form to provide matched characteristics. The prior art arrangement using only a single pair of transistors with their base emitter paths as a shunt on the signal path is described with respect to Fig. 1 (not shown).

Abstract: 1,162,229. Control of D.C. motors. SONY CORP. 17 Oct., 1966, No. 46256/66. Heading H2J. [Also in Division G3] In a system in which the speed of an electric motor 17, e.g. driving a magnetic tape capstan 15, is controlled by regulation of its current in response to the output of a low-pass filter 23 fed with signals from a generator 21 whose frequency represent actual speed, the motor is started at full current applied by switching means (transistor 28) responsive to the magnitude of the signal from the generator 21. The generator 21 comprises a pick-up head associated with a disc 19 driven by the motor and carrying permanent magnets 20. The signals from 21 are amplified at 22 and are applied to the filter 23 and to a rectifier 25. The filter output drops rapidly in a frequency range containing the desired speed; its output is "detected" at 26 and controls the conduction of transistors 33 and 34 and hence the motor current, which is energized with D.C. applied at B+ and earth. Manual adjustment is effected by rheostats 35 for fine control and 37, 38 for incremental control, which alter the response of the " detector " 26 to the filter output. At switch-on, transistor 28 is non-conducting and 33 and 34 are fully conducting. At a predetermined speed, below that in the controlled range, the output voltage from rectifier 25 is sufficient to make 28 conduct, thereby earthing the signal which made 33 fully conductive and its conduction is now controlled by the signal from 26.
