Title: Improvements in or relating to sheet feeding apparatus
Inventor: VOLLRATH KARL-HANS
IPC: B65H3/08
Filed: 1965-11-10
Abstract: 1,073,806. Feeding sheets. DRUCKMASCHINENWERKE LEIPZIG VEB. Nov. 10, 1965, No. 47672/65. Heading B6B. A sheet separated from a pile by a suction device is conveyed to intermediate guides from which it passes to a sheet-finishing or other machine by a conveying sucker 12 carried by a bar 6, cam mechanism being provided whereby the suckers 12 can be moved lengthwise relatively to the bar 6 during the movements of the bar. The bar 6 is reciprocated lengthwise for conveying the sheet by means of a rod 3 pivoted thereto at 11<SP>11</SP> and fixed to an oscillating shaft 1. An oscillatory movement about the pivot 11<SP>11</SP> is given to the bar 6 from an oscillatory shaft 2 by a linkage 9, 10 connected to the bar at 11<SP>1</SP> so that the sucker 12 returns to its sheet receiving position along a different horizontal path to that it takes during a conveying movement. The bar 6 has a tubular extension 7 in which the sucker 12 can slide and through which suction is applied to the sucker. A spring 13 is situated between the sucker and the end of the bar 6. Pivoted to the sucker is a link 20 connected to a lever 18 pivoted at 19 to the rod 3. A roller 16 on the lever 18 engages a fixed but adjustable cam 14 having a circular part R with projecting parts 22, 23 at its ends. The angle subtended by the circular part is equal to the angle of oscillation of the shaft 1 so that if the cam is adjusted so that the roller 16 engages only that part, the sucker movement is the same as that of the bar 6. If, however, the cam 14 is adjusted angularly relatively to the shaft 1 by means of a rod 15 pivoted thereto, either the cam part 23 acting on the roller 16 causes the sucker 12 to move rearwardly relatively to the bar 6 at the end of a rearward movement of the bar or the cam part 22 causes a relative forward movement of the sucker at the end of a conveying movement. Two such suckers with their operating means may be mounted on the shafts 1, 2 and be independently adjustable along the shafts according to the size of sheet and also so that they may take sheets separated from one or the other of two adjacent piles of sheets.

Title: Optimum seismic velocity filters
Inventor: FOSTER MANUS READ
IPC: G01V1/28
Filed: 1967-10-20
Abstract: 1,208,424. Seismic prospecting. MOBIL OIL CORP. 20 Oct., 1967, No. 47885/67. Heading H4D. A method of filtering coherent noise from n seismic data traces derived from n spaced detectors in response to generation of a seismic disturbance comprises applying each of the traces to a different one of n filters each having an amplitude spectrum G j (#) given by the equation: where i is #-1, e is the base of Naperian logarithms, j represents successive integers between - n/2 and +n/2 (excluding zero), m represents successive integers betweenn/2 and +n/2 (excluding zero), # is the frequency of the seismic disturbance, T is the primary reflection moveout per trace, #T is the coherent noise moveout per trace, a j  is a number equal to the distance from a reference point to the detector producing the jth trace divided by the spacing between successive detectors, am is a similar number for the mth trace, # mj  is equal to 1 for m=j but is otherwise zero, R N (#) is the coherent noise-to-signal ratio, R U (#) is the random noise-to-signal ratio, p(#) is an assumed probability density function for primary reflection moveout, and #p(##) is an assumed probability density function for coherent noise moveout and summing the outputs of the filters to form a composite trace. Details are given of a FORTRAN programme for computing filter coefficients; the actual filtering may be done by digital computer or by analogue timedomain filters. The filtering separates primary and multiple reflections on the basis of their difference in apparent horizontal propagation velocities, permits upper and lower limits to be set on the velocities suppressed by the filtering, and permits account to be taken of the dependence of R N  and R U  on frequency for obtaining optimum suppression of multiple reflections.

Patent GB-1110870-A (GB)
Title: Improvements in or relating to television camera apparatus
IPC: G03B7/085
Filed: 1966-10-27
Abstract: 1,110,870. Television. GRUNDIG ELEKTRO-MECHANISCHE VERSUCHSANSTALT. 27 Oct., 1966 [27 Oct., 1965], No. 48246/66. Heading H4F. [Also in Division G3] A circuit arrangement for the automatic, continuous adjustment of an optical diaphragm in the optical path of a television camera, wherein a control voltage is derived which is related to the photo-electric current flowing in the camera tube, e.g. the signal plate voltage in a vidicon camera tube, comprises two Schmitt trigger circuits T 1 , T 2  and T 3 , T 4 , Fig. 1, responding respectively to variations of the control voltage E in opposite directions from a predetermined value to initiate flow of current through an electric motor M coupled to adjust the diaphragm to restore the control voltage and thus to minimize changes in the illumination of the camera tube. The control voltage is applied to the trigger circuits via an impedance matching transistor T 7 , and each trigger circuit has associated therewith a switching transistor T 6  and T 6  controlling the motor current. If the intensity of illumination on the lightsensitive screen of the vidicon increases the signal plate voltage drops, as a result trigger T 1 , T 2  changes over which opens switch T 5  connecting one terminal of the motor M to earth, the other terminal being connected to a re-chargeable cell Q; the motor thus starts and reduces the aperture of the diaphragm. If the intensity of illumination decreases trigger T 3 , T 4  changes over, opening switch T 6  which connects motor M to a - 6V line which thus opens the diaphragm. Voltage source Q is charged when the diaphragm is adjusted in the direction of a larger aperture, the charging current which is also the motor current flowing from the - 6V line. An additional low charging current flows constantly through resistor R 10 . Overrun of the motor M is prevented by mechanically controlled limit contacts k 1  and k 2 . When the camera is switched-off or in the absence of the mains voltage the diaphragm is completely closed automatically to prevent damage to the tube due to excessive or accidental exposure by arranging for a separate contact of the relay, which remotely switches on the supply voltage, to be connected between the emitter and collector of switch T 5 , Fig. 2, not shown. On failure of the mains voltage this contact closes connecting motor M to earth. This relay contact may be replaced by an electronic switch, Fig. 3, not shown.
