Title: Improvements in particle counter
IPC: G06M11/04
Filed: 1958-03-17
Abstract: 861,284. Particle counters. DU MONT LABORATORIES Inc., A. B. March 17, 1958 [March 15, 1957], No. 8522/58. Class 40(3) In a particle counter for counting the number of particles in a given area a signal produced in sensing means when a scanning beam encounters a particle is applied to a circuit which delays the signal for a period equal to the time between successive sweeps of the scanning means and the sensing signal and delayed signal are applied to an anticoincidence circuit which provides an output to counting means only when the sensing signal is not overlapped in time by the delayed signal. Light from the flying spot scanner 10, Fig. 2, is directed by the lens assembly 31 and mirror 32 to scan the transparent container 33 containing the particles to be counted. The mask 34 limits the counting area and the emerging light passes via the condensing lenses 35 and mirror 36 to the photocell 14. The output of the cell is applied via a cathode follower 15, Fig. 1, to a correction circuit 16 which ensures that the average signal valve remains substantially constant without appreciably degrading the signal information and a Schmitt trigger circuit 17 connected to the output of the correction circuit produces, when triggered, a signal of constant amplitude corresponding in duration to the width of the particle intercept. This signal is used to modulate the output of an R.F. oscillator 19 and the modulated signal is applied via an R.F. amplifier 20 to the delay line 21. The output signal of the line, delayed by the line scan period, is demodulated and applied to the record input of an anticoincidence circuit 24 which has a first input connected to the output of the Schmitt trigger circuit. The anticoincidence circuit provides an output when a pulse is present at the undelayed input only and this output is applied to the counter 25 and register 26. During the line fly back period a pulse is applied to the third anticoincidence circuit input terminal to prevent the passage of pulses during this period. To equalise the time delay and the line scan period, the pulse output of a blocking oscillator, Fig. 7 (not shown), having a natural time period larger than the delay time also modulates the R.F. carrier applied to the delay circuit, after demodulation this pulse is used to trigger the blocking oscillator thus equalising its time period and the delay time. A part of the blocking oscillator output is used to trigger the line scan. Specification 778, 288 is referred to.

Title: Shutter for Photographic Cameras, especially Studio Cameras.
Inventor: HANSEN JENS PETER
IPC: G03B9/48
Filed: 1916-06-23
Abstract: 100,749. Hansen, J. P. March 9, 1915, [Convention date]. Shutters.-To a frame 1 carrying the lens-board is attached a shutter board 2 with members 3, 4 to which are secured parallel cylinders 5, 6, adjustable for height and carrying co-operating feltcovered cardboard doors 7, 8. By the pressure of the felt around the cylinders against similar material upon the shutter board, noiseless operation is promoted, and the displaced air being thus forced to escape between the doors as they close, a pneumatic delay action is obtained. Operation is effected through the agency of an endless semistiff band 10 secured to the cylinders and also to itself at the mid-points so as to assume the position shown in Fig. 5 when the shutter is closed. When the usual pneumatic device 13 is inflated, a flat spring 12 is forced outwards and bent, carrying with it the central stretches of the band and opening the doors, which are kept in phase by a crossed cord passing around the cylinders, and are returned by an interconnecting spiral spring. To ensure an automatic closure of the shutter under certain conditions, as upon insertion of the plate &c., an horizontal spindle 17 has wings 18, 19 normally held down by flat springs 21 hut adapted to be momentarily displaced by pins 20 upon the door hinge, cylinders 5, 6 as the doors open, and to prevent subsequent closing of the shutter until the springs are lifted to allow the pins to pass by the movement of a screw or wedge derived from a plate-exchanging device or from the mirror of a reflex camera by means of a Bowden wire.

Filed: 1957-03-18
Abstract: 850,868. Printing machines. LARSEN, C. E. March 18, 1957 [March 21, 1956], No. 8876/57. Class 100(2) In a method of lithographic offset printing in which moisture is supplied to the offset blanket otherwise than from the printing plate, a damping agent in an atomised or pasty or gel-like condition is applied to the outer surface of the blanket. As shown the plate cylinder 1 is inked by a train of rollers 7-10 and damped by a second roller train 12-15. Paste damping agent 22 is contained in a trough 23 the bottom of which is formed by rollers 20, 21. The assembly 20-23 oscillates periodically about the axis of the roller 21 so as to bring the roller 20 into intermittent contact with the offset blanket on the offset cylinder 2 to which it transfers a quantity of the paste 22. The amount of damping agent transferred to the device can be regulated by a highly-polished chromium plated roller (not shown) which bears with adjustable pressure on the blanket between the points of contact of the latter with the roller 20 and the plate cylinder 1. The amount of agent supplied by the device 20-23 may be regulated so as to be sufficient to effect the entire damping of the plate in which case the damping train 12-15 is dispensed with. In a modification the blanket is damped by a jet from a liquid atomizer. The additional moisture may be supplied to the offset blanket either after it has made an impression, as shown, or before.

Abstract: 456,708. Fluid - pressure servomotorcontrol systems. TOMLINSON, A. V., 65, Victoria Street, Westminster.-(Compagnie des Freins Westinghouse; Establissements de Freinville, Sevran, France) March 25, 1936, No. 8913. [Class 135] A fluid-pressure servomotor system for operating the ailerons of aircraft and for other purposes has a follow-up control of the kind involving a moving seat for the central valve and is provided with means for automatically and mechanically locking the power device in its adjusted position. In the form shown in the Fig. the power device comprises a piston, formed of a packing 30 clamped between two plates 31, 32, movable in a cylinder 29 under the control of a manually actuated rotary disc valve. The seat for this valve is secured to a pulley connected by a flexible cable 17 working through tubes 11, 12 with a pulley 13 having a toothed sector 14 engaging a rack on a rod 22 moved by the piston, so that when the piston moves consequent on an adjustment of the control valve the seat is moved to restore the control to neutral. A pointer 18 indicates the completion of this action. The locking device comprises a quick pitched screw 28 rotatably mounted on the piston rod 37 and adapted to co-operate with a nut formed in the movable part of a clutch adapted to be pressed by a spring 36 into engagement with a mating part 35 formed on the cylinder cover. The lower part of the screwed member is connected by a ball bearing 23 with the rod 22 and is formed with a clutch part 26 adapted to co-operate with a clutch part 27 slidably but non-rotatably mounted on the rod and adapted to be pressed into engagement against the action of a spring 25 by the piston rod 37. When pressure is admitted to the cylinder, the piston moves slightly to engage the parts 26, 27 further movement depressing the part 39 against the action of the spring. The part 39 is now free to turn and the piston, if desired, moved to the end of its stroke. As soon as piston movement ceases the member 39 rises under spring action into locking engagement with the member 35. Initial movement of the piston in the reverse direction separates the parts 26, 27 thus permitting the screw to revolve during further movement of the piston.

Abstract: 1,223,153. Electroluminescence. MATSUSHITA ELECTRIC INDUSTRIAL CO. Ltd. 23 Feb., 1968 [24 Feb., 1967], No. 9032/68. Heading C4S. An electroluminescent device comprises a semi-conductive electroluminescent layer 103 comprising electroluminescent powder and resistive metal oxide powder (e.g. SnO 2 , TiO 2 , WO 3 , Sb 2 O 5 ), which reflects the luminescent light, the two powders being mixed in a vitreous medium, photoconductive layer 106, electrodes 102, 107 and A.C. and D.C. sources 110, 111 for applying superimposed voltages, the structure constituting a single series circuit (Fig. 1, not shown). The photo-conductive sensitivity of layer 106 under an A.C. voltage increases as the D.C. voltage increases and the D.C: resistance of the electroluminescent layer is lower than the D.C. resistance of the photo-conductive layer in the dark state. The electroluminescent layer may be 30 to 60 micron thick ZnS: CuAl mixed with varying amounts of semi-conductive and reflective metal oxide bound in a vitreous material, to control the resistivity. Relative gradings, softening points, expansion coefficients, and vitreous material examples are considered and electroluminescent layer resistivities in the range 10<SP>7</SP> to 10<SP>9</SP> ohm. cms. disclosed. 10 micron layer 104 may be of light reflective ferroelectric BaTiO 3  and SnO 2  or TiO 2  in a vitreous on plastic material, for ohmic and non- ohmic layers respectively and 10 micron semiconductive layer 105 may be black paint mixed with non-linear resistivity powder CdS: Cl or linear resistivity carbon black powder, these layers preventing breakdown and facilitating resistance matching. Also the raised dielectric constant reduces A.C. voltage losses in the intermediate layers. Photoconductive layer 106 may be 200 to 500 micron thick including plastics binder and sensitive to visible light X-rays, infra-red and ultra-violet rays. Photoconductive material may be CdS activated with a Group IB element (e.g. Cu, Ag) and a Group VII B  element (e.g. Cl) or a Group IIIB element (e.g. Al, Ga). To improve X-radiation sensitivity, ZnCdS:Ag phosphor may be added to photo-conduct ve CdS: Cu, Cl in a plastic binder the additions also increasing resistivity and dielectric strength. Al electrode 107 may be a parallel line mesh or lattice pattern. For feedback operation, layers 104 and 105 may be omitted and electroluminescent layer 103 a composite layer including a semi-conductive non-pervious layer, while for maximum sensitivity the electrode adjacent the electroluminescent layer is positive.
