Title: A device for indicating depth of focus in photographic cameras
IPC: G03B17/02
Filed: 1956-01-10
Abstract: 785,857. Photographic cameras. DECKEL, H., and DECKEL, F. W. Jan. 10, 1956 [Feb. 10, 1955], No. 839/56. Class 98(1) Means for indicating the depth of focus in a photographic camera include two indicating elements each movable by a pivoted lever, the levers being controlled by a common driving element through a cam slot from the lens diaphragm setting element. As shown in Fig. 1, rings 16, 18 carrying pointers 10, 12 which move over a scale of distance 14 are coupled to move equally in opposite directions, A lever 22, pivoted to a pin 26 carried by a fixed ring 28, has a pin 32 engaging a slot 36 in the ring 18. A lever 20 pivoted at 24 to the ring 28, has a pin 38 extending through a slot 42 in lever 22, and a pin 30 entering a slot 34 in the ring 16. The pin 38 enters a cam slot 46 on a ring 48 connected to the diaphragm setting member. When the diaphragm is set, the movement of ring 48 transmitted through the cam slot 46 and pin 38 to the levers 22, 20, causes the rings 16, 18, and their pointers 10, 12 to move equally in opposite direction to indicate on scale 14 the nearer and further limits of the field of definition. A system is described wherein the depth of focus indicator is incorporated in an interchangeable objective, the focusing scale and the diaphragm setting scale being mounted on the lens mount, and the shutter setting scale, to which the diaphragm scales may be detachably connected, being mounted on the camera bodies.

Title: Organo-metallic complexes of transition metals and process for their preparation
Inventor: HUEBEL KARL WALTER
IPC: C07F11/00
Filed: 1958-01-09
Abstract: The invention comprises complexes of formula MxAyBz wherein M represents a transition metal of the 6th, 7th or 8th sub-groups of the Periodic Table, B represents a carbonyl group, x is an integer from 1 to 4 inclusive, y is an integer from 1 to 4 inclusive, z is O or an integer from 1 to 8 inclusive, and A represents a group of formula <FORM:0913763/IV (b)/1> wherein X represents CO, CNR1, O, S, Se, SO2 or NR, R represents hydrogen or a hydrocarbon radical, R1 represents a hydrocarbon radical, R2, R3, R4 and R5 each represent hydrogen or an inorganic or organic group as defined.  These groups may be Cl, Si(CH3)3, -CN, -NR21, COOR1 (wherein R1 is hydrogen or a hydrocarbon radical) or a substituted or unsubstituted alkyl, aryl, aralkyl or alkaryl radical wherein the substituents may be e.g., halogen, phenyl, -CHO, -CN, -NO2 or -NR21.  The group A is p -bonded to the metal atom. Metals specified include iron, cobalt, nickel, ruthenium, rhodium, palladium, osmium, iridium, platinum, manganese, rhenium, chromium, molybdenum and tungsten.  Typical compounds include tetraphenyl cyclopentadienone ('tetracyclone') iron tricarbonyl, tetraphenyl-thiophene-dioxide iron tricarbonyl, bis(tetracyclone)di-iron, tetrakis (tetracyclone)tricobalt, and the triphenylphosphino-, -arsino-, and -stibino derivatives of tetracyclone iron dicarbonyl.  The complexes of the invention may be prepared by reacting a transition metal carbonyl or a derivative thereof with the compound A above.  The reaction may be carried out at a temperature from 40 DEG C. to 300 DEG C., in a neutral organic solvent, in a non-oxidising atmosphere and using preferably stoichiometric amounts of reactants.  Specified solvents include aromatic and paraffinic hydrocarbons such as benzene, toluene, xylene, petroleum ether and cyclohexane.  When the transition metal has an even number of electrons in its electronic shell e.g. chromium, molybdenum, tungsten, iron or nickel, the reaction product usually contains carbonyl groups. When the metal has an odd number of electrons in its shell e.g. manganese or cobalt, complexes in which z is O are generally obtained.  However, both types may exist, and in the reaction of iron tetra-carbonyl with tetracyclone almost quantitative yields of each are obtained.  Tetracyclone iron dicarbonyl triphenylphosphine [(tetracyclone)Fe(CO)2.P(C6H5)3] is obtained by heating stoichiometric amounts of tetracyclone iron tricarbonyl and triphenyl phosphine in benzene at about 120-140 DEG C. Bis (tetracyclone)cobalt hydride is obtained by treating a benzene suspension of tetrakis(tetracyclone)tricobalt with HCl gas.  The acidic hydrogen may be replaced by sodium or potassium; or by an acetyl or methyl radical by treatment with acetic anhydride or diazomethane.

Title: Detector
Inventor: HIRUPOTSUTO FURANKU BACHIERU
IPC: G01N27/90
Filed: 1996-01-05
Abstract: PROBLEM TO BE SOLVED: To detect the seam of main gas pipe by providing a transmission coil for transmitting a signal based on a driving current generated from a driving current generator, and a pair of receiving coils disposed oppositely to the transmission coil and detecting the voltage being induced when the magnetic coupling of receiving coil is different from that of the other receiving coil due to a discontinuous part present in the material. SOLUTION: A transmission coil 2 is disposed in the center of a sonde 1 and receiving coils 3, 4 are disposed in the axial direction at an interval of 20mm between the center of coil 3, 4 and the side face of coil 2. The coils 2, 3, 4 are disposed coaxially. An annular space 6 is present at a seam 5 between the end 7 of one pipe and the pipe socket 9 of the other pipe. Magnetic coupling is different between the pipe and the coils 3, 4 because the sonde 1 traverses the seam 5 while aligning one coil 3 with the space 6. When a rectangular current pulse of about 0.5A is fed for 50μsec from a drive unit to the coil 2, a different voltage is induced at a part where the magnetic coupling between the metal and the coil 3, 4 is different. The difference of the voltage is detected.

IPC: H03B28/00
Filed: 1992-01-06
Abstract: PURPOSE:To generate a sinusoidal wave with high accuracy, low distortion and variable frequency through the use of the circuit with a small number of components. CONSTITUTION:A counter 11 counts a clock CLK to obtain count results B0-B4 and they are converted into switching control signals D0-D10 by a control timing generating circuit 12. The timing is adjusted by a synchronizing circuit 13 they become switching control signals Q0-Q10 and they are given to a load resistor circuit 14. The load resistor circuit 14 voltage-divides potential sets VD2, VS2 by the resistance and the voltage divided potential is given sequentially to a low pass filter 15 by the switching control signals Q0-Q10. The low pass filter 15 consists of a switched capacitor in which a frequency fCLK of the clock CLK is used for a transmission zero point. Thus, the sine wave with high accuracy and low distortion is obtained and the sine wave whose frequency is variable is obtained while keeping an excellent high frequency suppression effect.

Filed: 1990-01-05
Abstract: PURPOSE:To obtain excellent fluidity and adhesion property of a lubricant to a protective film by using perfluoropolyether having a nitrobenzyl group on at least one end of the molecular chain for the lubricant layer.

Title: Method, system and use of the method or system for the application of lacquer
Inventor: NORSKOV LAURSEN UFFE
IPC: B27N7/00
Filed: 1999-04-07
Abstract: The invention concerns a method for the application of lacquer to edges on plates and lists, especially of the porous type which are used within the furniture industry, where by changing the CAD reference dimension of the edge profile lacquer dosing unit it is possible to apply differentiated amounts of lacquer to predetermined areas. The invention also concerns a system for the application of lacquer to the egdes on plates and lists, especially of the porous type used in the furniture industry. Among other things, the system comprises one or more application rollers (9), possibly with a groove (10) in the surface of the individual roller (9) which can correspond to the edge profile (18) to which the lacquer is to be applied. The CAD reference can also be changed in the profile groove (10) of the application roller (9), or in both the roller (9) and the dosing unit (11). By using several units or application rollers (9) in succession, a particularly fine surface is obtained by allowing the application roller (9) which is placed last in the direction in which the work piece (18) is fed, to rotate in the opposite direction, whereby the excess lacquer is removed while at the same time a very well-defined thickness of lacquer is achieved. The method and the system are especially applicable in the lacquering of chipboards and similar porous plates which are not homogeneous.
