Patent GB-1301391-A (GB)
IPC: G01H17/00
Filed: 1970-01-19
Abstract: 1301391 Measuring damping NATIONAL AERONAUTICS & SPACE ADMINISTRATION 19 Jan 1970 [24 Jan 1969] 2411/70 Heading G1U If a physical structure is excited by a single impulsive stimulus, a damped oscillation Fig.2(a) results and if these vibrations are converted into an electric signal by an appropriate transducer, the damping decrement of the structure may easily be determined. However, if impulsive stimuli randomly distributed in time, are applied to the structure a complex waveform Fig. 2(b) results. The present invention purports to derive the damping decrement of the structure by the following analysis of this complex waveform. The complex waveform, shown magnified in Fig.4(I) is applied via a switch 12, Fig.3, to two comparators 16, 18, the first 16 of which detects positive going passages through a reference level, Vref, of the complex waveform, such as A 1 , A 2  etc., Fig.4(I), and the second 18 of which detects negative going transitions such as B 1 , B 2 , etc. Upon detection of the first positive transition A 1  by the comparator 16, a flip-flop 22 is turned on to allow the sequential sampling of the complex waveform under the control of a clock 42 at instants a 1 , a 2 , ..., a n . These n samples are distributed by a switch 38 on to n leads 1, 2,...n, and form the first pulses shown on these leads in Fig.4(IV), (V), (VI) and (VII). In a similar way, the first negative transition B 1  also initiates a sampling sequences b 1 , b 2 , ..., b n , and these samples form the second pulses of the pairs of pulses shown in Fig. 4. The clock pulses controlling the b samples are randomly phased with respect to those controlling the a samples, and when the negative transition B 1  is detected a signal, on a lead 29, is transmitted to a flip-flop 10 to inhibit the application of the complex waveform to the comparators. This process, when the b sequence is completed may be repeated, or, to produce results more quickly, the circuit of Fig. 3 may be duplicated (as in Fig. 8 (not shown)) so that a second pair of a and b sequences, labelled "2nd stage A", and "2nd stage B", in Fig. 4(I) may be commenced before the first set is complete. In both cases, the pulses on the output leads, and there will be two pulses for each pair of sampling sequences - referred to as a "cycle" - are applied to averaging circuits (not shown) to produce the signals shown in Fig.5. Once these signals have become steady, they are sequentially sampled and displayed as a pattern of dots Fig.6A, on a c.r.t., and, according to the Specification, the damping decrement of the smooth curve that could be drawn through the dots represents the damping decrement of the structure under test.

Abstract: 1323662 Absorptiameter TATE & LYLE Ltd 7 Feb 1972 [18 Feb 1971] 4965/71 Heading G1A In an absorptiameter for measuring the optical density of a liquid in a sample cell of the kind wherein radiation from a source passes through the liquid and is received by a photo-sensitive device, means are provided for maintaining the light source at a constant intensity corresponding to the intensity required to give a full scale deflection on an associated meter when a standard reference cell (water or glass block) is used. A lamp source L.P. is arranged by means of a lens system to direct a beam of radiation through a narrow band interference filter and through a sample contained in a cell on to photo-cell P/C. The output of the photo-cell is fed to a voltage follower circuit constituted by an operational amplifier OA2. The operational amplifier's output is fed to a voltage comparator OA3 with a reference voltage fed via resistor R15. When a switch PB1 is operated a reed switch R5 is energized and the output of the voltage comparator is fed to a capacitor C5 and to the gate of a M.O.S.T. TR2 causing the drain source resistance to be varied to vary the energization of lamp L.P. (via operational amplifier OA1 and transistor TR) until such time as the circuit is in a stable balanced condition. The circuit components are adjusted so that in this balanced condition, the meter M1 reads full scale deflection. When the switch PB1 is released thereby allowing contacts R51 to open, the meter will remain set to full scale deflection by the action of capacitor C5 upon the M.O.S. transistor TR2.

Abstract: 1345166 Monitor systems for programmed control of machine tools PLESSEY CO Ltd 19 April 1971 [12 March 1970] 11817/70 Heading G3N A numerical control system for a machine 1, of the type in which a comparator 6 derives an error signal from signals respectively representative of desired and actual axis positions supplied by a store 5 and a transducer 7 and supplies the error signal to a control mechanism 10 for the relevant axis, is provided with a monitor system including a comparator 27 which receives the error signal from the comparator 6 and an error signal from a comparator 26 supplied with signals representative of the desired and actual axis positions from a store 22 and a transducer 16, the comparator 27 providing an output signal when the two error signals do not agree, which signal energises an error indicator light on a control panel 30 and is applied over a line 31 to inhibit the machine operation. The latter action may occur when the difference between the error signals becomes excessive and may constitute an alternative to the visual warning. The store 22 comprises a number of counters set to divide pulses supplied from a reference frequency source 23, so that the output frequency from the store is dependent upon the setting of the counters which setting is determined by the desired position data supplied from the machine programmer 2 via members 17, 19, 20, 21. Similarly a store 24 divides the pulses from the source 23 in accordance with the setting of its counters as determined by the signal supplied from transducer 16 via a pulse shaper 25. With correspondence of the signals from stores 22, 24, the comparator 26 will produce a predetermined or no output signal in accordance with the logic used. Comparator 26 also receives a signal from a manually adjustable tolerance dial 32 via a selector 33, which may receive information from the programmer 2 via member 19 so that the set tolerance may be over-ridden by the programmer or vice versa. The data in the store 22 is modified by signals from manually adjustable offset switches via a selector 34 to compensate for tool wear. Alternatively programmed offset data may be supplied to selector 34 from member 19. The machine is also provided with a second control loop to control an auxiliary function, such as coolant control, comprising a comparator 11 supplied with desired and actual values from members 4, 12 and providing an output signal to a machine control mechanism 14. The output signal of transducer 12 is also supplied to a comparator 37 of the monitor system for comparison with the desired value provided by a store 36, the output of comparator 37 forming an inhibit signal should its two input signals differ significantly. This signal may inhibit the machine 1 or control an auxiliary function mechanism 15.

As shown the station 50 is constituted by folding elements 51, 52 which are driven to operate in co-ordination with the feed roller 101, and the tension applied to the web can be varied, by adjustment of the pressure in the nip between roller 106 and a counterroller 107, to maintain longitudinal register of the web with respect to the folding operation. The web 11 is supplied from a reel 15 supported in bearing blocks 164 carried by lifting chains 160, the web being drawn from the roll by means of a roller 151 which is driven by a motor 152 controlled by magnetic proximity switches 155, 156 associated with a dancing roller 153 over which the web passes to form a storage loop, upstream of the feed roller 101.
