Abstract: 1,254,334. Programmed control of machine tools. SUPERIOR ELECTRIC CO. Sept.24, 1969 [Oct.10, 1968], No.46959/69. Heading G3N. A member is moved relative to another member by incremental movements selected along perpendicular axes so as to tend to cross a desired path, the speed at which each increment is carried out being controlled so as to maintain traversal of the desired path substantially constant. As shown, a digital position control system comprises a control unit 13 distributing pulses to X and Y axis pulse motors 11, 12 in dependence on pulses on a line 14, derived from input data on lines 44, from a punched tape not shown, by an error register 41 having an add-subtract gate 43. A signal on a line 42 provides a binary indication of the axis on which the future step is to be taken. The determination of past and now steps is effected by cascaded shift registers 46, 49 each of which introduces a one step delay. The feedback to gate 43 is derived from the now shift register and the now, past and future signals on lines 47, 50, 42 are fed through a logic circuit, comprising inverters 40, 48, 51 and NOR gates 34-39, providing a pulse pattern on lines 32, 33 to a uni-junction transistor oscillator 31. The oscillator 31 provides, in dependence on the pulse pattern, a pulse at normal rate to control unit 13 when the now step is in the same direction as the past pulse; when the past step differs from the now step, the rate is 1.4 normal when the future step differs from the now step and is 2.0 normal when the future step is in the same direction as the now step.

Abstract: 1312482 Frequency discriminators SOC ITALIANA TELECOMUNICAZIONI SIEMENS SpA 8 Oct 1970 [3 Dec 1969] 47888/70 Heading H3A A frequency demodulator comprises means RL for detecting null points of the signal f, a counter C N  and a timer T producing clock signals which are arranged to be counted by the counter, the counter being cleared on each occasion a pulse is produced by the null detector RL. The counter will be cleared by a first null in the input signal f and will then commence to count the clock pulses until after a predetermined count an output is produced as B U . If the input signal frequency is above a predetermined value, a second null in it will reset the counter before completion of the count, and no signal is produced at B U . For signals below this frequency, an output B U  is produced consisting of variable width pulses with a constant spacing, which is fed to a lowpass filter PB. At a second predetermined frequency the amplitude of the output from filter PB becomes sufficient to actuate a threshold circuit S to produce an output. The null detection is effected by feeding the input signal and the delayed input signal to NAND gates, Fig. 3 (not shown).

Abstract: 1,146,877. Repertory diallers. STANDARD TELEPHONES & CABLES Ltd. 25 Oct., 1967 [28 Oct., 1966], No. 48372/66. Heading H4K. [Also in Division H1] In a repertory dialler dialling impulses are produced by a counter 12, Fig. 4, in accordance with binary marks on a code bus 11, the code marks being applied in accordance with connections established between the code bus 11 and digit wires 6 successively energized by a counter 5 to read binary codes from successive columns of a punched card 7, the punched card being selected by a corresponding pushbutton which operates a contact set such as 10 to couple the bus to an individual set of wires associated with a pocket for the punched card. Each card has 15 columns and 5 rows, the fifth boing used to signal a next digit and consequent interdigital pause as measured out at 14. The digit wires 6 from counter 5 are conducting strips on a flexible plastics strap which, as seen in Fig. 5, is hung, with conducting strips uppermost, over every fourth one of flap plates pivoted on and hanging from notched rails 20. In the centre of each pocket formed by the strap 6 a contact carrying pivoted plate is hung, each face of such plate having a set of code wires flexibly connected to a push-button contact set, such as 10, for connection to the code bus 11, and each of these sets of code wires having projecting spring contact fingers to sense the perforations of a punched card carried in an adjacent pivoted frame, the fingers projecting through the card to contact the conductive strips of strap 6. The pivoting of all the members allows the stack to be tilted so as to squeeze the stack with a rubbing action that aids good contact. The tilting is produced by a cover, Figs. 1 and 2 (not shown), which when swung upwards to expose the stack allows the pivoted members to hang freely so that cards may be easily withdrawn and inserted. When closed, the cover cams the bottom edge of the stack to tilt it through a substantial angle. The top edges of the punched cards are visible through the cover and when tilted these edges provide convenient index strips in alignment with the corresponding push-buttons that connect them to the code bus.

Abstract: 1,270,530. Sampling apparatus. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. 23 Sept., 1969 [17 Oct., 1968], No. 49259/68. Heading B1X. [Also in Divisions B8, F1 and G1] A liquid sampling apparatus comprises a chamber 2 into which liquid is induced from a stream 7 via pipe 1 by application of suction to a pipe 3, and a U-tube containing liquid which forms a barometric seal. One branch 4 of the U-tube protrudes into the chamber and the other branch 5 has a liquid outlet 6 which in use is at a lower level than the chamber. Suction applied to the pipe 3 also causes liquid forming the seal to move towards the chamber 2. When the level in stream 7 is at its minimum the suction will be sufficient to raise liquid from the stream to a level slightly above rim 8, and to raise liquid forming the seal to the rim 8. When the level in stream 7 is above the minimum liquid from the stream will, upon application of suction, flow into the branch 4 of the U-tube from the chamber 2 until the level of liquid in the branch 5 is equal to that of the stream. Air is then admitted to the pipe 3 at such a rate that the level in the branch 5 will not rise until the liquid level in the chamber drops to the level of the rim 8. A quantity of liquid will subsequently pass through the outlet 6. The quantity dispensed through the outlet will be directly proportional to the liquid level in the channel 9. As illustrated weir 10 is so shaped that the flow rate of the liquid is directly proportional to its level and thus to the amount dispensed through the outlet in one operation. The apparatus may recycle automatically by using a timer controlling the opening and closing of valves in suction and vent lines connected to the pipe 3.
