Title: Photographic camera
IPC: G03B7/085
Filed: 1968-05-03
Abstract: 1,210,176. Photographic camera exposure control. AGFA-GEVAERT A.G. May 3, 1968 [May 5, 1967], No.21026/68. Heading G2A. A photographic camera has an exposure regulating device which includes a photo-electrically controlled diaphragm setting device 27 manually adjustable by member 31 for varying the sensitivity thereof, and a shutter retarding circuit 20 for varying the shutter speed of the camera in accordance with the intensity of illumination of a photoresistor 21 included in the circuit and located behind a light attenuating device 48, 49 controlled by the diaphragm setting device 27, the arrangement being such that upon a change in prevailing illumination the diaphragm aperture is varied but the illumination of photo-resistor and hence the shutter speed is kept constant, but upon manual adjustment of member 31, the diaphragm aperture is varied and the illumination of the photo-resistor 21 is varied with a corresponding variation in the shutter speed, the overall exposure valve remaining constant. A further photo-resistor 29 adjusts the sensitivity of the galvanometer, and a further light attenuating device 31, positioned in front of the photo-resistor 29, is moved by a pointer 33 set against a scale 34 calibrated in shutter speeds. The light attenuating device 48, 49 is connected to the diaphragm 44, 45 as shown, or alternatively the diaphragm itself may form the light attenuating device by reflection of light to the photo-resistor from the taking beam path A-A. Operation of shutter release lever 13 in the direction of arrow b closes an operating switch 23 so that the retarding circuit is ready to execute a switching process, and releases a blade drive disc 7 carrying a cam 18 which closes a control switch 19 to initiate the switching process. At the end of the period of time determined by the resistance of photo-resistance 21, a control magnet 22 is supplied with current and attracts a locking pawl 24 which allows shutter blade 6 to close the shutter. Flash exposure can be given by movement of pointer 33 to fully attenuate light incident upon photoresistor 29 and to switch the galvanometer sensitivity to one of two valves determined by resistors 52, 53, an extension 54 on covering vane 31 co-operating with a changeover contact 56.

Title: Improvements in or relating to processes and circuit arrangements for measuring signal phase distortion
IPC: H04B3/46
Filed: 1966-05-16
Abstract: 1,071,980. Measuring phase distortion. SIEMENS A. G. May 16, 1966 [May 17, 1965], No. 21602/66. Heading G1U. In an arrangement for determining phase distortion in e.g. a signal transmission system X, a first voltage representing the group transit time distortion in the system is derived from a frequency wobbulation measurement of the group transit time, and the first voltage is multiplied by a second produced by differentiation of a voltage proportional to the wobbulated measuring frequency. The product voltage is integrated to provide a voltage representing the phase distortion. The measurement of the group transit time of the system may be carried out by a known method wherein a wobbulated signal U m  is derived by frequency modulating the signal from a variable frequency greater 1 by a wobbulator 3 and mixing the resultant signal in a modulator 4 by a carrier oscillation U 2  of frequency f 2  amplitude modulated by a voltage U 3  of frequency f3. The signal from the modulator 4 is passed via a low pass filter 8 and amplifier 9 to the system under test X. The output from the system passes via an amplifier 10 to a demodulator 12, which receives the modulating voltage U 3 . This is compared with a similar voltage U 3 ' of the same frequency derived from a reference generator 14 in a phase discriminator 13, which produces an output U #  of amplitude representing the phase difference between U 3  and U 3 ', thus indicating the group transit time distortion of the system X. The output voltage from the amplifier 10 is also fed to a frequency discriminator 11 which produces a voltage whose amplitude depends upon the instantaneous value of the carrier frequency of the signal U m . This voltage is differentiated at 18 and then passed to one input of a Hall plate multiplier 19 while the other multiplier input is supplied by the voltage U # . The multiplier output is integrated at 20 and amplified at 21. The measuring system output, representing the phase distortion produced by the system X, may be indicated at 23 or displayed relative to frequency on an oscilloscope 22.

Patent GB-689739-A (GB)
Title: Improved rust preventive composition
Inventor: PUTMAN JOHN HAROLD
IPC: C10M173/00
Filed: 1949-08-22
Abstract: A lubricating composition which has corrosion-preventive properties, especially rust preventive properties, comprises a lubricating oil, a minor proportion of an alkali metal benzoate, and a solubilizing agent which causes the benzoate to dissolve in the oil.  The lubricating oil may be a hydrocarbon oil or a synthetic oil, but is preferably a mineral oil.  The solubilizing agent is a material which, while being oil-soluble, enables the oil to take up and retain small quantities of water, suitable solubilizing agents being esters, ketones, alcohols, aldehydes and halogenated or nitrated compounds. Preferably, however, the solubilizing agents are oil-soluble metal petroleum sulphonates, i.e. mahogany sulphonates (particularly alkali metal or alkaline earth metal mahogany sulphonates) having molecular weights of 450 or over, or the C8 to C20 alcohols, particularly those mixed naturally-occurring alcohols contained in animal fatty bodies such as wool grease, lanoline or sperm oil.  The animal fatty bodies themselves may be employed as the solubilizing agents.  The alkali metal benzoate may be added to a lubricating oil containing the solubilizing agent or a mixture of alkali metal benzoate and solubilizing agent may be added to lubricating oil.  Alternatively, benzoic acid may be dissolved in the oil and a solubilizing agent containing free alkali added so that the alkali metal benzoate is formed in situ.  The composition should contain a small proportion of water and may also contain petrolatum, petroleum wax such as microcrystalline wax, volatile solvents or diluents such as white spirit and aliphatic alcohols (especially C3 to C12 alcohols), and antioxidants such as amines.  In the examples, compositions are described comprising (1) white spirit, sodium benzoate, sodium mahogany sulphonates dissolved in mineral oil, and lanoline, (2) mineral spindle oil, benzoic acid, and sodium mahogany sulphonates (containing free sodium hydroxide) dissolved in mineral oil, (3) mineral lubricating oil, petrolatum, sodium benzoate, and sodium mahogany sulphonates dissolved in mineral oil and (4) mineral spindle oil, sodium benzoate and polyoxethylene derivative of sorbitan mono-oleate.  The compositions of the examples are compared with similar compositions from which the sodium benzoate or benzoic acid has been omitted.
