Title: Improvements in de-inking printed waste paper
IPC: C09D9/04
Filed: 1964-08-07
Abstract: The reaction product of a protein hydrolysate and a fatty acyl compound is used as the deinking agent in the treatment of waste printed paper.  The hydrolysate may be obtained by acid or alkaline hydrolysis and may contain aminoacids and lower peptides or polypeptides.  It may be used in the form of a sulphate-containing alkali-metal salt of the condensation product.  The acyl group may be saturated or unsaturated and may contain 10 to 24 carbon atoms.  The acylating agent is preferably a fatty acyl halide, but the acids themselves, their anhydrides and acyl carbonates may be used.  The deinking agent is preferably added to water in the reactor before the waste paper is added, but may be sprayed on to the dry waste paper. The solution at this stage is preferably alkaline, and may be made so by the addition of sodium hydroxide, potassium hydroxide, soda ash or an alkaline-earth-metal hydroxide or salt.  After pulping, the material is diluted with water, separated, washed, thickened, acidified e.g. with alum, sulphuric acid or SO2, thickened and formed into a web.  The recovered stock may be blended with virgin sulphate or sulphite stock.

Title: Improvements in or relating to arrangements comprising an x-ray device having an x-ray image intensifier tube
IPC: H04N5/32
Filed: 1954-11-09
Abstract: 761,636. X-ray apparatus. PHILIPS ELECTRICAL INDUSTRIES, Ltd. Nov. 9, 1954 [Nov. 12,1953], No. 32403/54. Class 98(1) In X-ray apparatus including an electronic image intensifier, an objective lens and a magnifying lens are mounted behind the output screen, and a light-diffusing screen, which may be removable, is placed at the region wherein an image of the output screen is formed by the objective. As shown, an image IV of an object II is produced on the output screen 6 of an image intensifier 4 by means of an X-ray tube 1. An objective lens 8 and a mirror 9 produce an image of the screen at V, and this image is seen as a virtual image VI formed by a lens 11, which appears as an image VII after reflection at a mirror 13. The mirrors and lenses may be mounted in a housing 18, rotatable about the axis of lens 8. The exit pupil for direct observation is of diameter d 14. If a plate of frosted glass 10 is placed at V, the light is diffused and the exit pupil is enlarged to diameter d 17, and can therefore be more easily found. The image will be brightest where formed by rays passing directly through the plate 10, so the position of the original exit pupil may easily be found, the plate then being retracted for direct observation. The plate may be frosted only in parts, e.g. an annulus or parallel strips, with an area of clear glass between; in this case the plate need not be retracted.

[Also in Groups II and VI] A plurality of tobacco threshing and winnowing machines are arranged side by side and fed from a mutual cross-feed comprising a series of in-feed conveyers such as 10, 10a, Fig. 2, alternating with a series of out-feed conveyers such as 64, the feed to each machine being variably bled off between its in-feed and outfeed conveyers by a pivoted shoot H adjustable through a linkage 34, 36, 38, 42 so that its floor 16 allows a selected flow of leaves to pass via a gate valve 62 and crossed spreader plates 74, 76 to a conveyer 70. The quantity fed is adjusted by the setting of a slidable stop 156 co-acting with an abutment 154 on the link 42. Machine overload reacts on the control box of the electric driving motors and energizes a solenoid 58 to withdraw a pawl 48 holding the link 42 in adjusted position and allow a weight 60 to turn the shoot H so that ts floor 16 cuts off the feed to the valve 62.

Title: Apparatus for measuring and tele-transmitting the values of a given parameter
IPC: G01N27/16
Filed: 1960-09-23
Abstract: 913,566. Measuring systems. CHARBONNAGES DE FRANCE. Sept. 23, 1960 [Sept. 25, 1959 (2)], No. 32851/60. Class 40 (1). [Also in Group XXXVI] A signal whose frequency represents the value of a variable is obtained from a circuit comprising a measuring bridge in the feed-back loop of an amplifier, so that the circuit oscillates at a frequency depending on the degree of unbalance of the bridge, the amplifier output circuit being tuned to the central frequency of the band to be covered, this being preferably the frequency generated when the bridge is balanced. The Figure shows the application of the invention to the measurement of the amount of combustible gas in a mixture by catalytic combustion on a filament. Filaments 1 and 2 are supplied with D.C. from a battery 28 via a transistor stabilizer 29, and arranged so that they are respectively above and below the temperature at which catalytic combustion occurs, so that the difference between their resistances represents the amount of combustible gas present. The output of the bridge is taken from a potentiometer 9 which is preset so that the bridge is balanced for a predetermined amount of combustible gas, e.g. 50%. The bridge is fed, in parallel with the D.C. supply, from the output of a 3-stage transistor amplifier 6 via a transformer 5 which is tuned by capacitors 19 and 20 to the mid-band of the frequency range to be covered. The A.C. output from the bridge is fed back to a transformer 26 at the input of the amplifier together with direct feed-back through a resistor 8 and phase-shifting capacitor 7. The circuit will oscillate at a frequency depending on the amounts of resistance and capacitance in the feed-back paths and hence on the impedance presented by the bridge of the A.C. signals. An output signal of this frequency is passed via capacitors 22 and lines 21 to a remote indicating position. The same lines carry D.C. to operate a contactor 27 for switching on the circuit. A local indication is provided by a meter 24 which measures the D.C. unbalance of the bridge when the contactor is operated manually. The effects of ambient temperature changes are minimized by a negative temperature-coefficient resistor 8<SP>1</SP> in the feed-back loop.
