Filed: 1974-11-18
Abstract: 1457687 Measuring peak values of voltages SIEMENS AG 18 Nov 1974 [5 Dec 1973] 49889/74 Heading G1U To measure the actual peak-to-peak of an A.C. input, compensation is provided for the threshold voltages of the rectifying diodes. A three-phase supply T is full-wave rectified by diodes n1 - n6. The rectifying diodes produce an error voltage due to their finite voltage drop whilst conducting. This error is doubled by two compensation diodes n9, n 10 matched with the rectifying diodes. A high gain amplifier p utilizes negative feedback to ensure its two input voltages are substantially equal. Thus the voltage drop across n9, n10 ensures the voltage drop across R2 is equal thereto but opposite in sign. R3 is made equal to R2 and thus the whole voltage drop U 3  across R2, R3 is equal to the total error voltage. The output voltage U 2  is thus the true peak-to-peak value.

Abstract: 1,253,812. Unwinding bobbins. SHAWNDEL FLYERS Ltd. 14 Feb., 1969 [14 Nov., 1967], No. 51665/67. Heading D1J. A flyer for paying out wire from a bobbin comprises a head 5 rotatably mounted on a spindle 1 rotatable in a sleeve 2 which is located within the centre of the bobbin. The wire passes around rollers 37 and under rollers 23, 24 on a carriage 21 rockable about a pivot pin 22. The carriage 21 is biassed toward the position shown in Fig. 1 by a lever 25 pivoted to the carriage at 25a and spring 26 anchored to the head 5, the spring tension being adjustable by a nut 29. Normally a pin 19 in the head 5, engaged at 20 by the carriage 21, engages a peg 18 transmitting rotational motion of the head 5 via a spiral spring 15 to the spindle 1 and a disc 14 fixed thereto, which engages a friction disc 4 fixed to the sleeve 2, thereby resisting rotation of the head and applying a constant tension to the wire, which can be preset by an adjustment nut 13. However, the carriage pivots about pin 22 if the wire tension exceeds a preset value, due for example to faulty winding of the bobbin, this movement lifting pin 19 and thus releasing the friction device, so that the portion of the excessive tension applied thereby is relieved. The tension at which this occurs is preset by adjustment of the nut 29. Additionally, if the rate of withdrawal of wire exceeds a limiting value, centrifugal force acting on a weight 35 rooks a lever 32 to pivot the carriage 21 and thus release the friction device. Adjustment of the critical speed is made by movement of the weight 35 on threaded rod 34. On return to a sub-critical tension or speed the pin 19 reengages peg 18, re-winding the spring 15 and then setting disc 14 in motion against friction pad 4 as before.

Abstract: 1,224,322. Photographic processing control. LOGETRONICS Inc. Nov. 1, 1968 [April 17, 1968j, No.51980/68. Heading G2A. In order to control a photographic film processing apparatus (e.g. as regards chemical concentration, temperature, etc), a preliminary exposure is made of a test strip, which may be a separate piece of film, or an unexposed edge of the film sheet itself. Fig. 1 shows the complete processing apparatus, comprising a feed and control section 10, a processing section 11 and a drier section 12. At one side of the feed platform 14 over which a film sheet is passed to enter the processing section 11 between rollers 15, is incorporated a housing 16 enclosing the test exposure section, shown in more detail in Fig. 4. This comprises a movable platen 38 of sandwich construction, consisting of a support element 85, and spaced apart from it a window element 86 having an interchangeable transparent part of variable density. Between elements 85 and 86 is a thin electro-luminescent lamp 39. The whole platen unit 38 is normally retracted upwards by springs 82, 83. Below platen 38, and normally spaced from it, is a resilient platen 20. In use, an unexposed corner of the exposed film sheet (or a suitable separate piece of identical unexposed film) is placed on platen 20, and a solenoid 37 is energized. This drives platen 38 downwards against springs 82, 83, so clamping the test film firmly between window 86 and lower platen 20. The lamp is now switched on for a predetermined time at a predetermined intensity, both of which can be varied as required.

Title: Magnetic film store
Inventor: CHANG HSU

Filed: 1964-12-02
Abstract: 1,079,500. Circuits employing bi-stable magnetic elements. INTERNATIONAL BUSINESS MACHINES CORPORATION. Dec. 23, 1964 [Jan. 13, 1964], No. 52303/64. Heading H3B. [Also in Division H1] In a magnetic uniaxial film element store in which information is stored by magnetizing the film along one direction or the other along the easy axis, the film element having an associated range or associated ranges of values of magnetization along the hard axis variation within which can cause, by a creeping action, the switching or destruction of the stored information, the element is subjected to a disturb magnetic field which acts along the hard axis and varies within the range or a range and a bias magnetic field along the hard axis, the resultant of the bias and disturbs fields lying outside the associated range or ranges. It is stated that wall creeping is produced in both thick and thin magnetic films when the films are subjected to alternating fields in the hard direction of value 0À2 H K  to 0À3 H K  for thick films and 0À3 H K  to 0 for thin films, Figs. 3, 4 (not shown). Since in word orientated memory systems the word field in a selected word or line can produce a strong disturb field in the hard direction in the elements of lines adjacent to the selected word these elements may be switched. In accordance with the invention an electrical conductor or strip 50 is disposed over ground plane 12À1 to cover the film elements 10 and the current therethrough from battery 56 is adjusted by resistor 54 so as to provide a magnetic field 32À1 in the hard direction and having a value at least 0À2 H K  but not greater than 0À3 H K . Storage in the film is by passing a current of the appropriate polarity through the selected word line 18À1, 18À2, 18À3 coincidently with a current through the selected bit conductor 16À1, 16À2, 16À3. Read-out is by energization of the selected word line 18 such that the field produced thereby is less than H K  to enable non-destructive read-out. When thin films are employed the bias field must be in the direction of the disturb fields which is possible in the application of the invention to a magnetic store since a unipolar word drive pulse is employed. If thick films are employed, i.e. greater than 900 Angstroms, the hard axis bias field may be in or against the direction of the disturb fields provided the disturb fields are approximately 0À6 H K . Random fields may be eliminated by shielding. In the arrangement of Fig. 6 (not shown) the strip conductor of Fig. 5 is replaced by a Helmholtz coil arrangement. The bit and drive lines need not be orthogonal.
