Filed: 1970-06-29
Abstract: 1322880 Multiple lens COMPAGNIE GENERALE D'ELECTRICITE 29 June 1970 [24 Dec 1969] 43007/72 Heading G2J A multiple lens includes an array of individual lens elements 7, 10, each having at least three plane side faces, parallel to the optical axis, by which the element is joined to adjacent elements, the entire light-receiving end face 6 of some of the elements 7 being convex and part-spherical, and the end face 9 of the or each remaining element 10 being convex and part-cylindrical. The elements are preferably of rectangular cross-section, the elements 7 being preferably square. The focal points of the elements 7 and the focal lines of the elements 10 may lie on a curved surface but preferably will lie in a plane parallel to or coincident with the exit face of the system. In order to remove aberrations an element may be formed with a peripheral groove 12, Fig.4 (not shown) a cross-section 13 through the groove being circular (elements 7) or in the form of two semi-circles separated by a rectangle (elements 10). The elements may be cemented together, the cement containing absorbent particles such as carbon to prevent transfer of the light between the elements; in addition they may be held together by means of a frame or collars. The elements may be made from mono-crystals of magnesium fluoride or lithium fluoride, which are transparent in the far ultraviolet. The system may be used with a laser for producing a large number of very small perforations in a plate.

Title: An electrical indicating circuit for two-state devices

IPC: H03K17/18
Filed: 1959-12-18
Abstract: 913,137. Transistor multistable-state circuits. THOMPSON RAMO WOOLDRIDGE Inc. Dec. 18, 1959, No. 43167/59. Class 40 (6). [Also in Group XXXVI] A circuit which indicates whether two twostate circuits 10, 16 which repetitively change state at the same rate are in phase or are 180 degrees out of phase with each other, comprises a phase-sensitive circuit such as the AND-gate 22 to which the outputs of the two two-state circuits are applied and a switching circuit such as transistor 24 controlled by the phase-sensitive circuit so as to be repetitively switched thereby only when a particular one of the two possible phase relationships exists, a visual display device being coupled to the switching circuit so as to provide a visual indication when the switching circuit switches repetitively. In the arrangement shown, a neon lamp 50 is used as the display device; alternatively a meter, a " magic-eye " tube or a recorder may be used. Circuit 10 represents a bi-stable circuit switched to one state by clock pulses in a computer system, intermediate pulses restoring the circuit to its other state. Circuit 16 is similarly switched in synchronism with the clock pulses but with a phase dependent upon an output of the computer. Only when both inputs to the AND- gate 22 are in phase does a switching signal appear at the base of transistor 24; the interruption of the current in the primary winding of transformer 32 causes " ringing " in the stepped-up secondary of sufficient amplitude to energize the neon lamp 50.

Title: Improvements in or relating to circuit arrangements for correcting pin-cushion distortion in display tubes
IPC: H04N9/28
Filed: 1965-10-27
Abstract: 1,124,306. Cathode - ray tube circuits. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 27 Oct., 1965 [29 Oct., 1964; 12 Dec., 1964], No. 45480/65. Heading H4T. Pin-cushion distortion is corrected by modifying each orthogonal deflection sawtooth waveform in accordance with a parabolic function of the other. For correction in the East- West direction (assuming horizontal line scanning) a known arrangement is utilized which comprises a transductor 9 (Fig. 1) having a non-linear B/H characteristic and carrying a first (two-section) winding 11, 12 connected in shunt with the horizontal deflection coils 3 (fed from scanning generator 3) together with a second winding 16 connected to the vertical deflection circuit comprising generator 4 and deflection coils 7, 8. In operation, the inductance of the winding 11, 12 is varied as a parabolic (due to the transductor characteristic) function of the vertical frequency scanning current in winding 16 and the East-West correction then results from the effect of such variation in shunt with the horizontal deflection coils 3. This arrangement, however, is stated to be unsuitable for producing North-South correction since, owing to the essentially resistive nature of the internal impedance of the vertical deflection generator, the variable inductance (equivalent to winding 11, 12) must have a high value which, it is stated, gives rise to unwanted phase shifts. In accordance with the invention therefore, North-South correction is produced by utilizing the voltage of horizontal frequency induced in winding 16 (via winding 11, 12) such voltage, which is of incorrect phase, being substantially reversed in phase by capacitor 20 and coil 22 and then integrated by the vertical deflection coils 7, 8 so that the deflection current in the latter is suitably modified. The specification discusses the theory of operation of the arrangement and shows, inter alia, that the phase change produced by 20 and 22 cannot be exactly 180 degrees (since infinite values arise). In practice a phase change of about 170 degrees is produced. Other arrangements for producing the required phase shift include a secondary coil 28 coupled to the coil 22 and connected in parallel (Fig. 8, not shown) or in series (Fig. 9, not shown) with the vertical deflection coils and an arrangement similar to Fig. 1, but with the vertical deflection coils connected directly in series and the capacitor 20 in parallel therewith (Fig. 10, not shown).

As shown, the resistor 30 is arranged in a bridge circuit and a voltage U s  proportional to the heating current is supplied to an integrator 40 which is arranged to integrate a voltage proportional to J r  for the period T  p  by way of pulses of duration T p  provided by a bistable circuit 41 and trigger 18. During the ported T p  a capacitor in the integrator 40 is charged in dependence upon J r  to a voltage U 1 , see Fig. 3. The capacitor is then linearly discharged over a period t c  which is therefore proportional to the product of J r  and T  p . During the interval t c , a differentiator 42 provides a square pulse of duration t c , this pulse controlling a second integrator 43 to charge a second capacitor to a value U 2  in dependence upon J r  via the voltage U s . This second capacitor is then discharged linearly for a period t i  which is proportional to the product of J r  and t c  i.e. to the product of J r <SP>2</SP> and T  p .
