Title: Control circuit arrangement
IPC: G05F1/46
Filed: 1971-12-20
Abstract: 1343220 Amplifiers; lamp generators MULLARD Ltd 20 Dec 1971 59008/71 Heading H3T [Also in Division G1] In a control circuit for controlling the magnitude of a current flow in a path (between the terminals 9 and 10), a light source 14 powered by a control voltage illuminates a photo diode 6 connected in a bridge circuit comprising rectifiers 2, 3, 4, and 5 as shown, so as to provide current limiting in the path so that the magnitude of such current flow is a function of the intensity of light incident upon the photo diode from said light source as determined by said control voltage. The rectifiers are arranged so that no matter which way the current flows between the terminals 9 and 10 the photo diode 6 is always reversed biased. In a rate control arrangement for the rate control of an amplifier, an input signal V s  is applied to an operational amplifier 17 which operates as a voltage limiting amplifier, and provides at its output a voltage Vd of fixed magnitude and of the same polarity as the input signal. The driving voltage Vd produces a flow of current through the bridge circuit 1 and photo diode 6 to an inverting input terminal of the amplifier 18. The output voltage Vo increases at a rate determined by the integrating action of a capacitor 20 (connected as shown) and the current limiting effect of the photo diode 6 as determined by the control voltage applied at control terminals 15. However, a negative feed back path 22 provides a signal which opposes the input signal Vs and this negative feed back signal increases progressively until it nullifies the input signal Vs and thereby terminates the driving voltage Vd. The output voltage Vo thereafter remains constant until the input signal Vs is terminated following which the output voltage Vo decays at a rate determined by the capacitor 20 and the resistance of the photo diode 6 with the driving voltage Vd held negative during the decay due to the negative feed back.

Abstract: 1348640 Digital measurement SCIENCE RESEARCH COUNCIL 2 Sept 1971 [4 Sept Sept 1970] 42605/70 Heading G4H [Also in Division G1] A light beam 12 (Fig. 1) e.g. from a laser, is directed by a partially transparent mirror 6 on to a wedge shaped prism 5 so that interference bands are created between light incident on one surface of the prism and light reflected from the other surface, the interference bands being photo-electrically detected. In the embodiment of Fig. 1 light is incident on the movable prism at an angle α where sine α=n sin e (where n is the refractive index of the prism and e is the angle of the prism) so that light is reflected from the top surface of the prism and also reflected perpendicularly from the bottom surface. Several photo-electric detectors may be used in a digitizing head 10 so that the direction of movement of the prism may be determined. In the embodiment of Fig. 3, for two dimensional measurement, two prisms 5A, 5B at right angles to each other are mounted on a platform 16. An object is mounted on a platform 26, a desired point on the object being then placed beneath an objective length 24. The counts in a digitizing head 28A mounted over the prism 5A and in two heads 28B, 28C mounted above prism 5B are read out and then the platform 26 is moved to bring another desired point between the objective 24, a new reading of the count then being taken. Provided no angular movement of the platform 16 occurs the counts in heads 28B, 28C will remain in step but the counts may be combined in known manner to correct for errors induced by angular deviations.

Abstract: The invention relates to a simplified method for biologically cleaning almost any-sized area of soil which is contaminated with mineral oil-based hydrocarbons (MHC), and especially the leftover pollutants associated with mineral oil-based hydrocarbons. According to said method, the contaminated soil is treated with concentrated nutrients to stimulate and help the growth of MHC-consuming micro-organisms so that they can be cultivated and reproduce more quickly. The inventive method is characterised in that it is particularly easy to carry out and in that after a) advance dampening/watering if necessary, b1) the soil being cleaned is broken up to a considerable depth in at least one process, b2) the concentrated nutrients are added in the form of an aqueously dilute emulsion and/or dispersion, said concentrates being sprayed essentially evenly, also in at least one process, and c) the soil is then thoroughly re-watered. Steps b1) and b2) can be carried out once or repeatedly. The following sequences are preferable: (b1)=>(b2); (b2)=>(b1); (b1)=>(b2)=>(b1) or (b2)=>(b1)=>(b2).

Abstract: A secure system using a continuously-changing key that depends on the user's body part. A preferred embodiment obtains an image of the user's fingerprint and cements it according to a random generator. Only part of the image and not all of the image is sent at one time. The random segmentation insures that part of the image that is sent continuously varies from time to time. Therefore, an unauthorized receiver can receive only part but not all of the image. That only part of the image which is received will usually not be the same at the second as it is at the first time. Therefore, a received code cannot later be used to fool the system with the same credit card.
