Title: Improvements relating to reeling means
Inventor: ECKERSALL ROBERT
IPC: B65H19/22
Filed: 1960-11-28
Abstract: 915,915. Feeding webs. BIBBY & BARON Ltd. Sept. 18, 1961 [Nov. 28, 1960], No. 40769/60. Class 100 (1). Apparatus for winding and unwinding continuous webs comprises a reel shell supported by a reel bar 1 carried in swinging arms, one of which incorporates a shaft 4 for rotating the reel bar, and means whereby the rotation of the shaft can be caused to operate further means for transferring the reel bar longitudinally to move it out of or into the reel shell which is resting on a temporary support. The other swinging arm allows the reel bar to turn and slide freely. The swinging arm 2 shown in Fig. 1 incorporates the shaft 4 in its hollow centre. The shaft 4 for rotating the reel bar 1 drives a sleeve 8 via a pinion 6 and a crown-wheel 7. A key 9 slidable in a key-way 10 ensures that the bar 1 rotates with the shell 8, but allows it to slide longitudinally therein. The sleeve 8 carries a spindle 11 on which are fixed a worm 12 engaging a rack 13 on the bar 1, and a pinion 14 meshing with a ring 15 of internal teeth on a member 16 mounted on a bearing 17 on the sleeve 8. The member 16 normally rotates with the shell 8 but can be arrested by a brake band 18 surrounding it which is operated by a solenoid 19, Fig. 2 (not shown). When the member 16 is arrested, its teeth 15 drive the pinion 14 and the worm 12 which causes the bar 1 to travel longitudinally in the shell 8 and to move out of or into the reel shell (not illustrated) according to the direction of rotation of the shaft 4.

Filed: 1973-09-04
Abstract: 1414353 Controlling electro-plating of magnetic films I B M UNITED KINGDOM Ltd 4 Sept 1973 41475/73 Heading C7B [Also in Division G3] In electro-plating a ferromagnetic alloy film, e.g. of Fe-Ni, the current supply is varied to control the desired alloy composition by magnetizing at least a portion of the film to saturation during plating, and directing a beam of polarized light for reflection off the magnetized area, the reflected beam being intercepted and analyzed for changes in polarization due to the Kerr magnetooptic effect, a signal derived from such detected changes being used to control automatically the plating current. An alternating magnetic field may be used. As described an He-Ne laser directs plane polarized light through a window 71 of glass cell 60, the reflected light being intercepted by an analyzer set 2 degrees off extinction and passed to a photo-multiplier. The resulting signal has A.C. and D.C. components which vary respectively according to the changes in polarization of the light and reflectivity of the plated film. These voltage components are separated and amplified, the D.C. component being divided into the A.C. component to compensate for reflectivity changes. The final signal is applied to a differential amplifier which compares it with a desired fixed or variable signal and the resultant signal is used to control the plating current. The cell used may have a sliding plastics base 65 into which the substrate 68, e.g. a metallized glass slide, is held in a recess. Rod 74 is spring-loaded and provides electrical contact with the substrate. A Pt spiral anode 74 is used. Provision is made for a calomel electrode 76 which samples electrolyte via capillary 77 for calibration purposes, of which details are described. The bath disclosed comprises NiCl 2 , FeSO 4 , H 3 BO 3  and NaSCN in aqueous solution, the latter salt controlling the proportions of Fe and Ni in the alloy deposited.

Abstract: 1375609 Digital weighing RELIANCE ELECTRIC CO 13 Sept 1972 [30 Sept 1971] 42464/72 Heading G4H In an electronic weighing system in which the analogue weight signal from a transducer is amplified and converted to a pulse train which is fed to a counter and displayed, an initial count is set up in the counter and the pulse train counts the counter down to zero and then up to the displayed value. The apparatus incorporates automatic zero correction. As described, the analogue voltage is generated by load cell 11. The voltage produced is amplified in amplifier 12 and passed to gap fill circuit 14 which comprises a capacitor which stores the analogue voltage at the start of a zero setting period. The zero setting is controlled by "auto zero controller" 15 which, 120 times every second breaks the connection between amplifier 12 and gap fill circuit 14, disconnects the power supply to load cell 11 so that the input to amplifier 11 is zero and actuates auto zero circuit 13 which biases the input of amplifier 12 for zero output. The signal from the gap fill circuit is passed through low pass filter 16 which has a cut off lower than the zero setting frequency and is passed to dual ramp analogue to digital converter 17 in which the unknown voltage is integrated at 18 for a predetermined time and a reference voltage of opposite polarity is then integrated until the integrator output is zero as detected by comparator 22. During the integration of the reference voltage, clock pulses from 20 are fed to counter 21 which is preset with a tone value and is counted down to zero and then counted up. The counter reading is then transferrred to storage register 23 and may be displayed at 24 or fed to a printer or computer. An analogue overrange detector 26 which produces a warning when the analogue voltage exceeds a predetermined level and a digital over range detector 25 which produces a warning when the integration of the reference voltage does not reach zero within a specified time are also provided. A motion detector 27 comprising a differentiator produces on output (sync. pulse) when the analogue reading is steady and may be used to initiate transfer of the value in storage register 23 to the printer. The range and resolution of the device can be changed by incorporating dividers or multipliers between the clock 20 and counter 21. The circuitry may also be used as a digital voltmeter or, with a suitable sensor for measuring pressure.

Abstract: 1,244,699. Acoustic inspection of wood. WASHINGTON STATE UNIVERSITY RESEARCH FOUNDATION. 27 Aug., 1969 [13 Sept., 1968], No. 42680/69. Heading H4D. A wood specimen is graded according to mechanical properties determined by impacting the specimen and timing the propagation of the resulting energy wave along at least a preselected portion of the specimen. As shown, a log, veneer or plank S is supported by a clamp 10, 14 and roller and is struck by hammer 11. The wave propagation time for the portion between sensors 16, 17 is determined by timer 18 and between sensors 21, 22 by timer 23. From these times, and the dimensions and density of the specimen, the wave velocity and dynamic modulus of elasticity (either for the portions separately or as an average over the whole specimen) may be computed in a memory circuit actuating a grade marker. Weak portions may be identified from their wave velocities. The sensors may be of the contact-type (e.g. accelerometers) or non-contact type (e.g. shrouded conductors for detecting charges generated by the piezoelectric effect in wood).
