Title: Apparatus for measuring peak values and areas under peaks
IPC: G01R19/04
Filed: 1975-12-05
Abstract: 1487506 Measuring peaks and areas under peaks N I INST INTROSKOPII 5 Dec 1975 49989/75 Heading G1U An arrangement for measuring the peak value of a pulse 107, Fig. 6 of the type in which the contents 111 of a counter, after conversion to analogue form, are repeatedly compared with the instantaneous amplitude of the pulse and the counter is incremented whenever its count is below the pulse, is charactererized in that the increments to the counter are applied either to the stage of lowest significance, or, if the difference between the instantaneous count and the instantaneous amplitude of the pulse is sufficiently large, to a stage of higher significance, thereby causing the count to follow the rising edge of the pulse more closely. As described, the input pulse from an amplifier 2, Fig. 1, is applied direct to a first comparator 4 and via an attenuator to a second comparator 5, each comparator also receiving, from a D/A converter 16, a signal representing the count in a decade counter 13, 14. Whenever the first comparator 4 indicates that the count is below the pulse, a gate 10 is opened to apply clockpulses 12 to the lowest stage 14 of the counter, and if ever the second comparator 5 indicates that the count is below the attenuated pulse a second gate 11 is opened to allow the clockpulses to pass direct to a higher stage 13 of the counter. In a modification Fig. 2, (not shown) the integral of the input pulse is applied to the circuit of Fig. 1 so that the final count represents the area under the pulse, and in a further modification, the clockpulses that form this final count can be routed to a first counter (35) whilst the pulse is rising, and to a second counter (36) whilst it is falling, thereby measuring the area under the rising edge and the area under the trailing edge of the pulse. An appropriate D/A converter Fig. 3, (not shown) using weighted resistors, and a decoding circuit Fig. 4 (not shown) for driving seven-segment display tubes from the binary-coded decimal counters, are described.

Abstract: 1479514 Travelling wave shedding loom shuttles TSENTRALNY N I INST KHLOPCHATOBUMAZHONOI PROMYSHLENNOSTI 22 Nov 1974 [26 Nov 1973] 50685/74 Heading D1E A travelling wave shed loom shuttle 1 has, in the direction c of travel, a rear wall 21, a top wall 16, a bottom wall 17, a side wall 20 (Fig. 5, not shown) bearing on a reed, and a side wall 19 facing the beat-up discs 3, the side wall 19 being inclined at an angle α not exceeding 45‹ and having a height that gradually increases away from the tip 18. The shape of the shuttle acts as a shed clearer. The weft 33 normally laid by the shuttle 1 is directed by teeth 23 into disc slots 4 which move the weft towards the fell for beat-up by teeth 8. A badly laid weft is not so beaten-up and remains between the shuttle and the beat-up discs resulting in a smaller shed for the succeeding shuttle whose shape clears the shed enabling the two wefts, in different sheds, to be beaten-up simultaneously. The shuttle is driven in the shed by a roller 14 and, outside the shed, by a peg 14 on a conveyor 10 raised into a hole 25 in a spool support.

Filed: 1975-12-11
Abstract: 1527876 Feeding reams of paper on to a belt conveyer WRAPMATIC SpA 11 Dec 1975 [13 Dec 1974] 50773/75 Heading B8A A ream 2 of paper, the size of which may vary from ream to ream (c.f. Figs. 1 and 2), is drawn by a gripper 4 from a table 1 to a position on a conveyer belt 3, the gripper driving mechanism being such that the axis of symmetry of the ream is always coincident with the central axis of the belt. The gripper 4 is driven by a link 7 which is itself displaced from an initial position (dot-dash lines in Figs. 1 and 2) by a link 10 and a rotating crank 11. For reams of maximum size (Fig. 1) a pivot connection 29 between the link 10 and the crank 11 is at the maximum radius of the crank 11. For reams of smaller size (Fig. 2) the pivot 29 is moved radially inwards to a suitable degree. Also the centre of rotation of the crank 11 is displaced to the right progressively as the link 7 is deflected. The crank 11 is rotated by a motor 42 (Fig. 4) acting via belt 40, reduction gear 36; and gears 34 and 33. The latter gear is rigid with the crank 11 via a hollow shaft 21. The crank 11, its driving gear and motor are part of a mechanism 12, the whole of which is slidable on a shaft 13 to vary the centre of rotation of the crank 11. This is effected by a speed reducer 50 which operates via belt drive 48 and 51, a shaft 53, and right angle gearing 54 on a shaft 55. The latter is fixed axially, but free rotationally, in a fixed part of the machine frame 15, but has a threaded connection with the mechanism 12 thereby effecting the displacement of the latter. An electromagnetic coupling 47 connects the belt drive 48 with a shaft 32 having a bevel gear connection with a shaft 24 within the crank 11. This has a threaded connection with the mounting of the pivot 29. Thus when the coupling 47 is engaged, the pivot 29 moves along a slot 30 in the housing of the crank 11, to vary the effective throw of the latter.

Title: System for Transmitting Digital Traffic Signals
Inventor: DUUREN HENDRIK CORNELIS ANTHON
IPC: H04L1/00
Filed: 1966-11-22
Abstract: 1,159,441. Digital transmission systems. NETHERLANDS, POSTAL & TELECOMMUNICATION SERVICE, DIRECTOR GENERAL OF. 22 Nov., 1966 [3 Dec., 1965], No. 52292/66. Heading H4P. In a digital transmission system in which the input may have any of a number of bit-rates and character lengths, and in which errors in the received signals are corrected automatically by repetition, the input data is converted to an error-detecting constant-ratio code prior to transmission. Details of the code conversion, but not of the converter, are given. In the basic conversion, a 5-bit signal is converted to a 7-bit signal by the addition of two bits. In certain cases the 5-bit signal is converted e.g. by inversion to another 5-bit signal before the addition. Where longer codes are to be converted, e.g. from 8- to 11-unit, five of the bits in each character are converted to seven as in the basic conversion, the remaining bits being converted as detailed in the Specification. The embodiment of the transmission system described uses an eight character repetition cycle. In normal operation data in n-unit code from a tape is converted to the corresponding m-unit constant ratio code, the latter signals being transmitted and also stored. At the receiver the signals are converted to their original coding and passed to the output. Means is provided for synchronizing the local oscillator with the received signals. The receiver continuously sends a return signal comprising a succession of signals 1010 ... If error is detected in the received data, the receiver output is inhibited for eight characters and the return signal is inverted. Detection of the inversion at the transmitter causes the transmission from the store of seven previously transmitted characters, these being preceded by a signal alpha if the repetition starts at the same time as the 8-character cycle of the transmission system, but by a service signal I if its starts at any other time in the cycle. If two or more repetition-requesting signals are received successively, instead of a repetition cycle the transmitter sends the signal alpha followed by seven service signals I. This cycle is repeated until the receiver is correctly synchronized and has returned a non-inverted return signal, whereafter a normal repetition cycle is initiated.
