Title: Method and device for automatically controlling the exposure time for photographic purposes
IPC: G03B7/083
Filed: 1960-05-23
Abstract: 929,651. Photo-electric exposure control. MEOPTA, NARODNI PODNIK. May 23, 1960 [May 23, 1959], No. 18044/60. Class 40 (3). [Also in Groups XX and XL (c)] In a method of automatic exposure time control the resistance of a time switch circuit changes in dependence upon a photo-electric cell current. When a camera shutter is opened, contacts 29 close allowing a battery 30 to charge one of condensers 46, 47, 48 through the combined resistance of resistors 43 and 52, a transistor 42 and the electromagnet 31 which holds the shutter open. The resistance of transistor 42 is varied by the current flowing through the photo-cell 41 to control the rate of charging in dependence upon light intensity. When the condenser voltage reaches the ignition voltage of the diode 36, the resistance of a transistor 38 falls to short the electromagnet and close the shutter. This closes contacts 39 to discharge the condenser. Switches 53, 54, 45 may be changed over to connect up a voltage divider 50, 51 and a resistor 44 with an exposure time scale for manual setting. In a modification, Fig. 4 (not shown), the electromagnet is de-energized when the shutter is opened and the striking of the diode actuates a relay to energize it. In the embodiment of Fig. 6 (not shown), actuation of the release passes current to first electromagnets which open the shutter, and the relay causes this current to flow to second electromagnets to close the shutter. Film sensitivity is allowed for by selecting one of the condensers 18, 19, 20, and the slider of resistor 43 is linked to the diaphragm setting member. A plurality of interchangeable lens systems is provided in front of the photo-cell to limit its field of view, Fig. 7 (not shown). Specification 807,451 is referred to.

Abstract: 1,270,952. Separation of fatty acids and esters. KBAFTCO CORP. 9 April, 1969 [25 April, 1968], No. 18096/69. Heading C2C. [Also in Division C5] Mixtures of fatty acids and/or esters (above 10 C) are separated by cooling the fluid mixture in the presence of a lower boiling and immiscible fluid by subjecting the mixture and fluid to reduced pressure to evaporate the fluid, adding an aqueous solution of a surface active material to form an emulsion and separating the mixture into liquid and solid phases. Vegetable or animal fats e.g. tallow fatty acids or cottonseed oil may be treated and need not be completely melted. The fluid, e.g. water, may be introduced before the reduction of pressure or after and a temperature drop of from 25 to 120 F. per hour by the evaporation is desirable. The aqueous solution of surface active material, e.g. alkylphenolpolyglycol ether, alkylsulphonate, fatty alcohol sulphate and alkylbenzyl sulphonate, optionally with inert electrolytes such as magnesium, calcium, aluminium or other soluble metal salts, is added to the liquid phase and an emulsion is formed which is then separated by conventional methods such as decantation, filtration or by centrifuging.

Filed: 1928-06-22
Abstract: 294,102. Junkers, H. July 16, 1927, [Convention date]. Riveting; riveted joints; tube expanders.- Riveted joints where the work is accessible only from one side are made by employing a rivet with a hollow stem closed at one end, inserting this end so that it is on the inaccessible side, then deforming the closed end into a fixing head by a tool inserted into the open end of the stem. A suitable hand tool for deforming the heads comprises a pair of shanks having protuberances 13, 14, Fig. 3, adapted to be inserted in the rivet 3 and spread apart by pressing their handles 15, 16 together. The shanks are pivoted together at 10 and the tool is slightly rotated after each com- 'pression of the handles until the whole circumference of the head has been deformed. In a modification, the tool is mounted in a bush 20, Fig. 5, the handles are closed by a recessed member 40, normally pressed away from the work by a spring 52, a crank handle 46 being provided for rotating the tool. In a modification of this tool. for use where the work is not sufficiently rigid to take thrust, the handles are closed by opposed wedge-members 81, 91, Fig. 6, operated by pivoted handles connected to pairs of shanks 83, 93. In a further modification, the head is deformed by a disc 153, Fig. 13, eccentrically mounted in a block 150 provided with a part 151 shaped to enter the rivet, the block being slightly rotated for each turn of the shank 154 to cause the rivet head to be deformed around its whole circumference. A further modification comprises a single shank 122, Fig. 10, formed with an incline co-aperating with a rounded surface 141 normally raised from the work by a spring 160. The tool is mounted in a casing 130, the lower end of which is slotted to provide springy portions which engage the part 1 of the rivet in the manner of a chuck, cam surfaces 134, 135 closing the lower parts of the casing inwardly under the pressure of the spring 160. The spring is compressed, when it is desired to release the work, by hand actuated pins 165, 166. In the other forms of the tool, the head of the rivet mav be prevented from turning with the tool by the provision of projections on the tool holder engaging notches in the flange of the rivet.

Filed: 1947-07-10
Abstract: 643,578. Automatic circuit-breakers. SUNBEAM CORPORATION. July 10, 1947, No. 18311. Convention date, June 26. 1939. [Class 38(v)] [Also in Groups VI, XI and XXXII] An automatic electric toaster comprises an oven member having at one end a chamber containing thermostatic timing means for measuring the toasting interval and at the other end a chamber containing switching means which is controlled by a lever from the timing means to terminate the toasting period. Bread slices are placed on the racks 128, 129 and the handle 122 depressed causing pairs of links 131, 132 to move down and simultaneously rotate shafts 141, 135. Boiler 165 thus engages cam finger 152 and rotates switch lever 146 which closes main contacts 147, 149 and causes finger 156, Fig. 4, to engage in notch 159 of lever 158 thereby latching the switch in its closed position. Depression of handle 122 also causes rod 144 at the opposite end of links 131, 132 to rise, and engaging a hook, Fig. 2 (not shown), it moves finger 176 into a position where it is latched by a pawl, Fig. 12 (not shown). The closing of contacts 147, 149 connects heater elements 62, 63, 64 and thermostat heater resistance 231 to the supply thus commencing the toasting period. The ply metal strip 205 of the thermostat control is adjustably heated by resistance 231 to permit variation of toasting time, cylindrical reflector 237 being rotatably mounted and controlled by knob 124. When the strip 205 is heated to a predetermined temperature it snaps down against surface 246, engaging the end 247 of lever 158 which tips and unlatches the finger 156 of switch lever 146, thus opening contacts 147, 149 and terminating the toasting period. An auxiliary thermostat member, Fig. 9 (not shown), compensates for the change in temperature of the mass of the toaster due to repeated toasting operations. Control knob 123 may be set to allow links 131-132 to move back to the bread-receiving position after the toasting period, or to hold finger 176 which permits the toast to remain lowered for further drying until manually removed. Specification 471,579 is referred to.

Filed: 1973-04-18
Abstract: 1426803 Selective printing INTERNATIONAL BUSINESS MACHINES CORP 18 April 1973 [15 May 1972] 18588/73 Heading B6F [Also in Division G4] An ink jet printer incorporates means for controlling the phase relation between drop charging and drop formation. A clock 20 and a vibrator drive 18 cause a transducer 16 to vibrate a nozzle 14 to produce ink drops which are charged by electrode 22 and deflected by electrodes 31 on to a record medium 33. Electrode 22 (also connected to clock 20) receives information charge signals from a character generator 26, and discard charge signals (e.g. a sawtooth waveform) from a circuit 30 for those drops not carrying information. A gutter 32 collects the discard drops. When no phase correction is required, the discard drops are being formed at or near the middle of the sawtooth waveform, and they fall into area B of the gutter, to be detected by electrode 32E (a few drops may also fall into area C). If the drops fall in area A (sensed by electrode 32D) or in C but not in B, then phase correction is required. Detectors 34, 36 and gates 38, 46 detect the condition A+AÀB and cause a monostable 40 and a trigger 42 to actuate a voltage source 44; this controls a delay circuit 28 to adjust the relative phase by 180 degrees. In the embodiments of Figs. 2-4 (not shown) a 4-level voltage source and a 4-position delay circuit may be used to provide 90 degree phase corrections; alternatively a continuous voltage source and a continuous delay may be used. The gutter comprises sensor plates 92, 96 having cutaway portions 93 containing electrodes 94, 95. Plates 101, 102 and a separator 98 are provided, and apertures 108 &c. allow the ink to be drained away.

Abstract: 595,885. Multiplex systems. CREED & CO., Ltd. July 20, 1945, No. 18642. Convention date, Sept. 6, 1944. [Class 40 (iv)] A multi-channel high-frequency carrier transmission system comprises means for grouping the individual channels into a plurality of basic groups, each group consisting of the same number of channels occupying the same section of the frequency band covered by the system at the lower end of the said band, means for translating upwards the frequency band of certain of the basic groups in order to form a plurality of unit groups, each unit group consisting of the same number of basic groups arranged respectively to occupy adjacent frequency bands, the same for all unit groups, means for repeating the process to form a plurality of larger unit groups, means for translating upwards the frequency band of at least one of the larger unit groups so that it occupies a frequency band adjacent to and above the band occupied by another larger unit group, and means for transmitting these larger unit groups over a single transmission path. As shown, Fig. 1, a 72 channel two-way telegraph system comprises eight basic groups a to h, each of nine channels, the frequencies of which range from 750 cps. to 3150 cps. with a 300 cycles channel separation. The basic groups b, d, f and h are each translated upwards by a modulator M1 using a 3.3 kc. carrier, the output of which passes to a band pass filter F 1 and is combined with that of a filter F comprising basic groups a, c, e, g respectively and four unit groups are formed of frequencies from 600 cps. to 6600 cps. The output of the filters F and F1 of the second and fourth unit groups respectively are translated upwards by modulators M2, using a 6.9 kc. carrier, filtered by band-pass filters F2 and combined with the first and third unit groups respectively to form two larger unit groups of frequencies from 600 cps. to 13,500 cps. The second of these larger unit groups, comprising basic groups e to h, is further translated by modulator M3, using a 15 kc. carrier, filtered by filter F3 and together with the other larger unit group is then translated by modulator M4, using a 34.5 kc. carrier, filtered by filters F4 and amplified before passing to the outgoing line L. Similar arrangements are made for reception at R<1>, Fig. 2. The arrangements for transmission from T<1>, Fig. 2, to R, Fig. 1, in the reverse direction are similar, differing only in the omission of the final modulator M4 and the substitution of filters F5 for F4.
