Title: Frequency to direct current converter
IPC: H03K5/04
Filed: 1970-08-21
Abstract: 1,256,199. Frequency discriminators. GENERAL ELECTRIC CO. 21 Aug., 1970 [21 Aug., 1969], No. 40362/70. Heading H3A. A frequency discriminator comprises a first bi-stable circuit 2 having an input terminal C coupled to an input signal and an output terminal Q coupled to an input terminal of a second bi-stable circuit 3, an output terminal Q of which is coupled to a reset input R of the first bi-stable circuit and a clock source 5 connected to a trigger input C of the second bi-stable circuit. In one embodiment, Fig. 1, both bistables are JK flip-flops, the first of which, 2, has its J input connected to a "1" and its trigger input C fed with the input signal. A first input pulse triggers bi-stable 2 to its "set" state to apply a "1" at the J input of bi-stable 3 so that the arrival of the next clock pulse at trigger input C of bi-stable 3 will cause this to set. The next clock pulse will then reset bi-stable 3 to produce an output at Q which will reset bistable 2. The resulting output at 6 is thus a pulse train having a pulse width equal to the time period of one cycle of the clock source, and a pulse rate dependent on that of the input signal. This signal is fed to an integrator 38, 39 via a FET switching circuit 35, 36 which ensures that the pulses are constant amplitude. In a second embodiment, Fig. 3, the first bistable 51 is a set/reset type and is set by a first pulse in the input signal. Its output is coupled via a NAND gate 61 and a divider 67 to the K input of the second bi-stable 75, and the clock source 65 is coupled to the other NAND input and to the trigger input C of the second bi-stable. After an input pulse sets bi-stable 51, NAND 61 is enabled to feed clock pulses to counter 67 and at the end of the count period an input is provided to the K input of bi-stable 75. The next clock pulse at C then produces at output 73 a signal which resets bi-stable 51. The resulting output 6 is as before, but is extracted from the first bi-stable 51.

Further positive feedback provided by the resistor 6 is opposed by the output from transistors 16, 17 to limit the amplitude of oscillation to 10 V. Temperature compensation is provided by diodes 27. The input to the transistors 16, 17 is fed via resistor 8 which controls the limiting point, and resistor 9 which controls the relative positive and negative clipping points.

Title: Circular Weaving Looms

Abstract: 1,160,581. Circular dummy shuttle loom.PELTZER & FILS S.A. 12 Sept., 1966 [17 Sept., 1965], No. 40571/66. Heading D1E. The invention relates to a loom for weaving three fabrics disposed in a circle, the weft being inserted by dummy shuttles loaded with weft at gaps between the fabrics. Each shuttle comprises a platform 21 attached to a flange 32 on which are mounted three grooved wheels 43; the middle wheel runs on a bottom track 51 in the form of a comb, and the end wheels run on a similar top track 50. Three grooved pulleys 69, 70, 71 are mounted on the shuttle, and two more 89, 91 are mounted on stub shafts 85, 87 carried by a horizontal shaft on the stationary part of the loom. As described in specification 1160584, a weft thread is held across the path of the shuttle between the stationary pulleys 89, 91 and the pulleys 69-71 on the approaching shuttle, so that as the shuttle passes, the weft is drawn into zigzag loops; when sufficient weft for a pick has thus been drawn from the supply, the shaft 81 is turned through half a revolution to disengage the pulleys 89, 91 from the weft, which is thereby deposited on the platform of the shuttle and then laid by it in the shed. The half turn imparted to the shaft 81 brings a duplicate pair of pulleys 88, 90 into position to co-operate with the next shuttle. The shaft 81 is constantly urged to rotate by an air turbine, and is permitted to turn half a revolution at the appropriate times by an escapement mechanism operated by an electromagnet. Specifications 1160582, 1160583 and 1160585 are also referred to.

Abstract: 1,269,906. Analogue to digital converter; forming products and integrals. COMPAGNIE DES COMPTEURS. 27 Aug., 1970 [22 Oct., 1969], No. 41283/70. Headings G4G and G4H] In an analogue to digital converter, an input signal X and an input signal Y are converted into a train of pulses, the number of which represents the integral of the product of X and Y. Signal X is converted by modulator 10 into a signal G1 in which the mark space ratio is proportional to X. The conversion is achieved by means of an integrator 11, and a comparator 12 which causes the sign of the charging voltage V1 to switch over each time the comparator changes state. Signal G1 is fed to an exclusive OR gate 24, and signal G3 from the exclusive OR gate operates a switch 20, controlling the input of the analogue signal Y to an integrator 21. The signal entering integrator 21 represents the product of X and Y. The output of integrator 21 is fed to comparator 22 which compares the signal with either one of fixed reference voltages E2 or E1 the reference voltage being chosen by reference to the output state of the comparator. In this way the number of pulses produced by the comparator is representative of the integral of the product of X and Y. Errors due to parasitic current produced by the modulator are eliminated by causing the input of one of the variables to be inverted periodically. This may be achieved by means of the exclusive OR gate 24 which causes G3 to be the reverse of G1 if G2 is in the " one " state. Alternatively an inverter and switch may be inserted in the input of either X or Y.

Abstract: 939,841. Semi-conductor devices. PYE Ltd. Dec. 23, 1959 [Dec. 24, 1958], No. 41724/58. Drawings to Specification. Class 37. Method of producing a junction region in a semi-conductor material comprises placing a piece of a metallic impurity, e.g. indium, characteristic of one conductivity type on the surface of a piece of semi-conductor material, e.g. germanium, containing an impurity characteristic of the opposite conductivity type, heating the assembly until the adjacent portions of the pieces melt and become partially alloyed together, allowing the molten portions to solidify and recrystallize, removing the remaining piece of metallic impurity by dissolving it in a solvent, e.g. hydrochloric acid or mercury, which has only a slight effect on the semi-conductor material, and attaching, e.g. by soldering, a smaller piece of metallic impurity than the original piece and characteristic of the same conductivity type, e.g. indium, to the central area of the recrystallized zone. The semi-conductor material can be subjected to heat treatment after the original piece of metallic impurity has been removed therefrom in order to remove strains formed during the alloying process. The recrystallized zone can form a dish-shaped depression in the surface of the semi-conductor material. Junction regions can be formed on two opposite surfaces of the piece of semi-conductor material to form the emitter and collector regions of a junction transistor. The method can be employed for producing a junction region in a semi-conductor diode device. Specification 939,842 is referred to.
