Title: Improvements in or relating to cathode-ray tubes
IPC: H01J29/62
Filed: 1932-05-30
Abstract: 402,781. Cathode-ray tubes. SIEMENSSCHUCKERTWERKE AKT.-GES., Siemensstadt, Berlin. May 30, 1932, No. 15328. Convention date, May 30, 1931. [Class 39 (i).] Cathode-ray beams are caused to converge to a point or to be divergent or parallel, without changing the central axis of the beam, by means of electrostatically charged diaphragms in the form of flat rings symmetrically surrounding the axis of the beam and having an orifice of diameter greater than that of the beam, the diaphragms not taking part in the production of the beam and acting on the beam after it has passed the anode. The diaphragms are apertured discs or circular rings or combinations of these as in Figs. 8 and 9, in which the disc 1 and ring 2 are differently or oppositely charged. In Fig. 9, two discs 1, 3 are connected together to enclose the ring 2. The aperture in the diaphragm may be twice as large as the crosssectional area of the beam, the field increasing with the distance from the axis so that the rays are deflected to a greater extent at a distance from the axis. Negatively and positively charged diaphragms produce convergence and divergence respectively and correspond to convex and concave lenses for light rays. An image-magnifying device corresponding to the microscope can be produced by combinations of diaphragms. The acceleration of the rays by the field of the diaphragm on one side counteracts the retardation on the other side. In Fig. 5, rays drawn from the cathode k by an anode not shown are formed into a parallel beam by a diaphragm b<1> and made convergent by a diaphragm b<2>. As the deflection of a ray depends on its velocity, the rays passing through the aperture in the screen b<3> connected to the cathode are of uniform velocity. The homogeneous beam is made again convergent by a diaphragm b<4> the potential of which is varied to vary the number of electrons passing through the aperture in a screen b<5> and so to modulate the intensity of the beam made convergent or parallel by a diaphragm b<6>. The beam is deflected to scan the screen s by plates a<1>, a<2> and is focussed on to the screen to produce a sharp spot of light. The diaphragm b<4>, b<6> may be at the same potential and equidistant from the screen b<5>.

Abstract: 555,467. Photographic shutters. KODAK, Ltd (Eastman Kodak Co.). Oct. 31, 1942, No. 15339. [A Specification was laid open to inspection under Sect. 91 of the Acts, June 4, 1943] [Class 98 (i)] In a photographic shutter of the type in which a master member, after tensioning and upon release from the set condition, operates a bladering through a latch, the master-member comprises a pair of co-axially mounted parts, of which one is connected with the setting-lever and is held in set position by the trigger and the other is connected by the latch to the blade ring, the two parts being connected by a lostmotion device so that the first part gathers momentum before commencing to drive the second, whereby a more rapid opening of the blades is achieved. The application of the invention to the shutter described in Specification 491,885 is illustrated. The master member comprises two parts mounted on a stud 6, the first being a disc 8 to which the driving spring (not shown) is attached, and the second a plate 16 to which is pivoted the latch 19 which engages a lug 22 on the blade-operating ring 5. A lug 17 on the plate 16 extends into an arcuate slot 18 in the disc 8, forming the lost-motion connection between the two. The disc 8 is rotated to the set position shown by operation of a setting-arm 11 which slides an arcuate member carrying a rack 9 which engages a pinion 7 secured to the disc. On operation of the latch 13 by the release trigger the disc 8 moves idly and gathers momentum until the other end of the slot strikes the lug 17, causing rapid movement of the plate 16 and hence of the blade ring.

Title: Transistor driver circuit
IPC: H03K17/0422
Filed: 1957-05-15
Abstract: 808,331. Transistor pulse amplifying circuits. NATIONAL CASH REGISTER CO. May 15, 1957 [June 8, 1956], No. 15373/57. Class 40 (6). In a circuit employing a transistor 11 to the base of which an input pulse 23 is applied, a feedback circuit 16 is arranged to prevent current flowing in the base circuit from exceeding a certain value. By connecting the diode 16 to the collector and a tapping on the base resistor 19, the collector is prevented from rising to such a potential that saturation of the transistor occurs. The resistor 19 is shunted by a capacitor 21 to ensure the maintenance of a sharp leading pulse edge. When the input pulse 23 occurs at time t1, Fig. 2, the collector potential rises rapidly to near earth but is prevented from entering the saturation region due to diode 16 becoming conductive to pass current through part of resistor 19, thereby preventing any further rise in base and collector current. At the end of the pulse, t2, the positive-going edge is fed over capacitor 21 to the base to drive out minority carriers, thereby terminating the output pulse 24. The waveform 36 is that which would result in the absence of feedback diode 16.

Additional material and a protecting layer of graphite, coal dust, or slag h may be supplied through a pipe i. Various methods are employed to increase circulation of the bath metal. In one arrangement magnetic poles are disposed laterally at different parts of the tube c. In other modifications the tube has limbs of unequal diameter. In a further modification a fire brick plug is arranged in one limb to decrease its effective cross section and is adjustable therein longitudinally. Circulation may also be increased by cooling one limb. In Fig. 7 an annular container q filled with molten copper short circuits a part of one limb. The container may be replaced by an interchangeable rod of good conducting material clamped on the limb. In a final modification the "pinch" effect is artificially produced by restricting the cross section at a point in the tube. Two or three metal baths according to the number of phases of the supply current, may be interconnected to heat a common hardening bath. Guiding ribs may be employed to conduct the circulating fluid where required.

Abstract: 1476880 Character recognition programmable logic circuit INTERNATIONAL BUSINESS MACHINES CORP 17 April 1975 [24 June 1974 (2)] 15770/75 Heading G4R A logic circuit arrangement for use in a character recognition device has a shift register SR1- 48 feeding a plurality of programmable logic circuits P AND 1-48. Data representing for instance a scanning matric 40 Î 24 is fed serially to a 960 bit shift register formed of 48 20 bit sections. Each section feeds a plurality of programmable AND circuits 1-48 each of which produces a one bit output which is fed back to 64 feedback latches which also feed the P AND circuits. Selected P AND circuits 37-48 also feed output latches. The P AND circuits may be as shown in Fig. 8C for a three input gate in which latches 115, 116, 124, 125, 133, 134 are set to determine the logic operation. If both latches for an input are zero the inverters, e.g. 119, 120 for input A feed "1"s to AND gate 123. If only one is zero then either A or A is fed to gate 123. OR functions are produced using inverters and de Morgan's theorem A - B = A + B. The shift register may contain dummy registers which are not connected to the logic circuits to reduce the number of connections required while still storing the same number of bits. Thus portions of an area are processed alternately (Fig. 14, not shown).
