Title: Process for impregnating webs of fibrous material, in particular paper
IPC: D21H17/22
Filed: 1938-05-13
Abstract: A size for impregnating fibrous materials comprises a mixture of animal size, formaldehyde and hydrogen peroxide to delay hardening. The hydrogen peroxide, 30 per cent, may be 1-2 per cent of the solution or up to 50 per cent of the quantity of formaldehyde. Specified animal sizes are bone glue, hide glue, glutin, blood serum and hen's egg albumen.  In an example, a solution was prepared by adding 5 parts of glycerine, 1-2 parts of hydrogen peroxide and 4 parts of 40 per cent formaldehyde to 7 parts of glutin which had been swollen with 83 parts of water and heated to 60 DEG  C.  To increase adhesive, 1-2 parts of starch may be added.  A small quantity of emulsifiable fat, e.g. 3-5 per cent of olein or wool fat, may be added to increase flexibility. Fine metal powder, e.g. aluminium bronze, may be added for decorative purposes.

Abstract: 1279049 Electron microscopes; lasers BALZERS PATENT UND BETEILIGUNGS AG 24 March 1970 [28 April 1969] 14356/70 Headings H1C and H1D In an electron emission microscope means are provided for exciting photo-emission from the specimen by monochromatic light and by polychromatic light. The monochromatic source is preferably a laser and may operate on a fixed or on a variable wavelength. In Fig. 3 six lasers 17 are mounted on a rotatable turret, and the polychromatic source comprises a high pressure mercury vapour lamp 20; diaphragms 15 and 16 which may be of the iris type provide control of the intensity of the light which passes to an anode 2 and is reflected on to the specimen 7. The image end of the microscope may include two movable fluorescent screens 4 and 4a, Fig. 4, one of which is provided with an adjustable aperture through which electrons may pass to a Faraday cage 23, to photographic apparatus 22, or to an electron velocity analyser in the form of a lens 24, a diaphragm 25 and an electronmultiplier 26. In use the polychromatic light source is used to provide a general picture of the specimen, and subsequently the monochromatic light is used instead or in addition to provide a different contrast pattern. The threshold voltage for photo-emission at different parts of the specimen may be determined by observations with monochromatic light of different wavelength.

Title: Improvements in or relating to the preparation of non-odorous 2-methyl-4-chlorophenoxyacetic acid and its application as a selective weed-killer
IPC: C07C51/363
Filed: 1953-05-21
Abstract: 2-Methyl-4-chlorophenoxyacetic acid is prepared by reacting o-cresol with an alkali metal chloracetate in alkaline solution and treating the reaction liquid at pH above 8 (with or without recovering unchanged o-cresol) with a hypochlorite.  This latter step results in an odourless product.  The hypochlorite (preferably sodium) may be added as a separate solution or may be formed by passing chlorine into the alkaline reaction liquid, with further addition of alkali to maintain the pH above 8.  The product may if desired be separated by acidification and may be converted into salts and esters.  Examples are given of the process with and without steam distillation to remove the bulk of the unchanged o-cresol.  Specifications 592,827 and 683,131 are referred to.ALSO:Non-odorous solutions of alkali 2-methyl-4-chlorophenoxyacetates (containing also inorganic salts) are obtained by reacting o-cresol with an alkali chloracetate in alkaline solution and treating the reaction liquid at pH above 8 (with or without recovering unchanged o-cresol) with a hypochlorite or chlorine and alkali.  The latter treatment decomposes residual o-cresol without forming chlorocresols and the product is odourless and does not cause turbidity in hard water. Examples are given of the process.

Title: Improvements in variable speed friction gearing
IPC: F16H15/42
Filed: 1925-06-04
Abstract: 242,901. Gill, C. H. June 4, 1925. Variable-speed friction gearing comprises pulleys on parallel shafts connected by a friction ring encircling both shafts. Cone discs 17 are screwed to a driving-shaft 16 by threads 80, Fig. 5, of opposite hand so as to tend to separate. The transmission ring 36 makes connection with a like pulley comprising cones 28 which, however, tend to come together. The whole gear is controlled automatically by a spring 91 acting on pivoted levers 88, or the spring may be assisted by manual control. When the driving pulley 17 is opened right out, the ring 36 is lifted clear of the pulleys to disconnect the drive by a roller 45, Fig. 1, on a lever 48. At the same time a spring-pressed catch roller 40 snaps over a shoulder 23, and so holds the pulley cones 17 separated. In the application to a vehicle shown in Figs. 1 and 2, two such variable gears are used to drive road-wheel axles 25 independently. The shaft 16 is driven through a worm pair 14, 15 from an engine shaft 13, no main clutch or differential being necessary. Reversed driving is effected from the shaft 13 through a second worm pair 49, 50 and shaft 51. The shaft 51 is geared to each of the axles 25 by a ring 58 passing over two non-variable grooved pulleys 52, 53. The drive cannot pass back from a pulley 53 to a ring 58. The reverse is brought in by a clutch 60, which is double, the other set of teeth and reversing-train 78 being brought into action when coasting, using the engine as a brake. When the clutch 60 is in neutral, the rings 58 are raised out of gear by levers 71,. Fig. 1.

Title: Detector for monitoring rotation of an electrical machine
IPC: H02P25/024
Filed: 1974-04-02
Abstract: 1459600 Machine rotation monitoring system LICENTIA PATENT-VERWALTUNGS GmbH 2 April 1974 [4 April 1973] 14579/74 Heading G1A A device for monitoring rotation of an electrical machine comprises a disc drivable by the rotor of the machine and co-operating with a light source and five detectors, three detectors being associated with means at one radius of the disc and matched to the pole configuration of the machine, and two detectors being associated with a finely divided scale at another radius of the disc. As shown, Fig. 1, the windings of a synchronous converter machine are fed with three phase current by a frequency changer 11 of the type using thyristors fed with D.C. power by rectification of the mains input. The thyristors are fired by a control circuit 10 fed with information as to the rotor position and speed. The rotor carries a disc 2 having at its centre a pole structure 23 for a tachoalternator 3 the output of which is rectified and applied to an element 9 to produce an output signal proportional to the rotor speed. The outer edge of disc 2 is shaped to form a number of teeth related to the pole configuration of the machine 12. Two sets of three detectors 53, 4, 5: 63, 4, 5 which may be photo-transistors are positioned to provide appropriate switching pulses for controlling the machine. If the machine has one stator winding the two sets of detectors provide a redundant arrangement but if the machine has two stator windings spaced each detector set controls one winding. Each set of three detectors is associated with a further pair of detectors 51, 2; 61, 2 scanning closely spaced slits 22 to provide pulses which can be counted up to a given level after a starting angle determined by the outer coarse scale to pro-  vide a fine (1 degree) control of the load angle of the machine. The fine associated detectors of each set cooperate with a single light source provided with a system of reflectors and condensing lenses to distribute the light to the appropriate points. Alternatively fibre optics can be used to distribute the light. The source may be a lamp or a LED. The tacho-alternator may also be used to provide the power supply for the electronic system.
