Title: Production of consolidated planar products
IPC: D04H1/498
Filed: 1972-07-04
Abstract: 1384144 Laminated fibrous materials TEXTILKOMBINAT COTTBUS VEB 4 July 1972 31277/72 Heading B5N [Also in Division D1] One or more polypropylene films are irradiated with electron beams and mono-axially stretched before or after being contacted with one or more webs comprising non-thermoplastic fibres; the combination is then mechanically consolidated by the needles of a needle beam or of a sewing-knitting machine or by a calender and also heated. The fibres may be cotton, viscose rayon or polyacrylonitrile, e.g. as a corded web. Localized bonding may be produced by localized heating using pulsed laser beams to produce bonds in the form of points, parallel lines or two sets of parallel lines which cross at an angle, by heated needles or by calendering. The electron bombardment produces polymerization initiating species with a significant life. Such species are destroyed where localized bonding is produced by laser beam, but elsewhere the species cause graft polymerization if the web is immersed in a bath of aqueous acrylic acid at 70‹ C. or brought into contact with unsaturated polyester resin. The acrylic acid solution contains a dye with is taken up where graft polymerization occurs to produce a patterned fabric.

Abstract: 760,456. Treating charge ; utilizing unvaporized fuel ; charge mixing devices. AUGUST, P. Oct. 29, 1954, No. 31282/54. Class 7 (2). In apparatus for collecting and utilizing unvaporized fuel, at a point situated between the carburetter and the fuel air mixture port of the cylinder there is provided a fuel condensate collecting means comprising an annular member projecting into the passage connecting the carburetter with the port in a direction opposite the flow direction of the fuel air mixture for gathering condensed fuel particles travelling along the inner wall of the passage and for providing a ring channel which is connected with heating means capable of heating and gasefying the fuel condensate the heating means being in turn connected with mixing means arranged directly at the mixture port capable of reintroducing the gasefied fuel condensate into the flow of the fuel air mixture as directly drawn in from the carburetter and of thoroughly mixing the condensate and the fuel air mixture by imparting to these mixture components opposite rotatery motions. In Fig. 1 condensed fuel particles from a carburetter 5 are collected by a member 2 and pass to an exhaust heated chamber 8 and are then returned to the mixture stream through oblique channels 22. Helical guide grooves 18 impart a rotary motion to the mixture opposite to that imparted by the oblique channels 22 to the fuel gases. The heat exchanging tubes may be internally nickel plated or coated with another catalytic material. A cracking process may be performed therein. A pipe 23 leads to a source of water vapour e.g. the radiator and a valve 24 is conveniently operatively connected with the throttle valve 25 so that the pipe 23 is opened for the supply of water vapour when the engine operates at higher speeds. In Figs. 3 to 5 chamber 10 is connected by a passage 7 with the annular collecting groove 3 for collecting condensed fuel particles. Chamber 28 is interposed in the exhaust pipe a heat exchanging body 29 transmitting heat to the fuel condensate in the chamber 10. Helical guide grooves 18 are provided on the inner wall of the member 19. The passage 13, Fig. 4, leads to the chamber 10. The ribs 30 as far as they extend into the chamber 10 and channel 7 may be made of or coated with a catalytic material. Figs 6 and 7 show another embodiment with a condensate collecting groove 3.

Title: Improvements in or relating to means for measuring, indicating, recording and/or controlling a variable
Inventor: CULLEN GRAEME EYRES
IPC: G01R17/08
Filed: 1954-11-01
Abstract: 789,079. Electric tests. KELVIN & HUGHES, Ltd. Dec. 9, 1955 [Nov. 1, 1954], No. 31503/54. Class 37. [Also in Group XXXVIII] A physical variable is translated into an equivalent force acting on a lever 22 (Fig. 6) associated with a switch 24, 25 and is opposed by the electromagnetic force of a solenoid 28 energized via the switch, whereby the switch makes and breaks contact at a rate giving an average current through the solenoid which produces dynamic balance of the system, the current being measured by a meter 30 whose indication is proportional to the magnitude of the physical variable. The effect of solenoid 28 may be augmented by an auxiliary coil 70 connected in parallel with coil 28 through an RC circuit whose time constant gives either a quick make or quick break to switch contacts 24, 25. The force may be derived from the beam of a weighing machine, or from a bimetallic element, being proportional to temperature, or from a Venturi meter measuring fluid flow, the pressure difference being applied to a diaphragm 36 (Fig. 2) to produce the force on lever 22, the counter-balancing force being produced on a soft iron armature 41 movable in the field produced by solenoid 28, whereby both the current in coil 28 and the fluid flow are proportional to the square root of the balancing forces, and are therefore directly proportional to each other. Hysteresis effects in the core 29 may be removed by a further coil wound on the core and intermittently fed from the A.C. supply through a rectifier and gas-filled diode. The apparatus may be used to measure an E.M.F. at terminals 50, 51 (Fig. 4) by opposing it with an E.M.F. across a resistor 53 until the difference produces the current in coil 28 giving dynamic balance at the switch 24, 25. The current in meter 30 is then proportional to the E.M.F. at terminals 50, 51. The resistor 53 may be temperature-sensitive to provide automatic temperature compensation.

Filed: 1923-12-21
Abstract: 232,655. Shore, W. E. Dec. 21, 1923. Spray burners; oil supply fittings.-A fuel oil nebulizing apparatus comprises a high-speed rotary vacuum pump 1, Fig. 1, the suction inlet of which is fitted with a casing 6, containing a regulable oil admission nozzle 7 and provided with apertures controlled by a perforated disc valve 11 so as to admit a limited quantity of gas or air. The pump rotor 2 carries vanes 4 and is arranged eccentrically in a jacketed chamber 3. The oil drawn through the nozzle 7 by the movement of the rotor is partially broken up by the flow of air or gas through the casing 6 and is then separated into very fine particles by the rarefaction caused by the expansion of the gaseous medium. Reduction of temperature during this expansion is prevented by the circulation of a heating medium through the chamber jacket 14. Upon the vanes 4 moving past the outlet ports there will be an inrush of the previously discharged fuel and air mixture, causing a rise of temperature of the mixture between the vanes. The oil is drawn from a supply tank 13 through a filter 12 to which an emulsifying agent may be supplied through a tube 12'. Condensation in the pump chamber is collected in a chamber 15 and is preferably conveyed back to the nozzle 7, the excess passing through a check valve 16 to the tank 13. In order to boost the flow of the oil and air mixture to furnaces the discharge from the pump may be connected either to the inlet or to the outlet of a blower, suitable control valves being provided.

Abstract: 1,158,028. Levelling mobile tower cranes. PRIESTMAN BROS. Ltd. 20 June, 1968 [13 July, 1967], No. 32353/67. Addition to 1,120,164. Heading B8B. To level a bedplate 7, Fig. 1, which supports a tower crane or other civil engineering machine, an operator turns a switch 22, Fig. 2 (not shown) to position B to lower a hook 9 into engagement with an anchor pin 11 and lock the superstructure relative to the chassis by engaging locks 14, 16. The ground level is next determined by rotating a control box casing 23, Figs. 3, 5 until a spirit level 30 gives a zero reading and a second level 31 extends away down the line of maximum slope of the ground. One of the hand wheels 33 is now rotated to tilt a plate 28 upwards until the spirit level 31, which is mounted on it, gives a zero reading. Simultaneously a shutter 36 moves under a cut-out 39 so that the intersections X, Y between red and green halves of the shutter with the outer edge of the semicircular cut-out 39 indicate the two directions to which thicker parts of the two wedge rings 12, 13, Fig. 1, must be rotated to level the superstructure. Movement of the switch 22 to position C disengages the lock 14 between the lower wedge ring 12 and the chassis 8. The two wedge rings are now rotated by a slewing pinion 18 until a green pointer arm 41b, Fig. 3, overlies the intersection X between the green half 36b of the shutter and the edge of the cut-out 39. This puts the lower wedge ring 12 in its final position. The control switch 22 is now turned to position D to re-engage the lock 14 and indicate this engagement. Rotation of the switch to position E, disengages the lock 16 between the upper and lower wedge rings and produces a signal that this lock is disengaged whilst the upper wedge ring 13 is rotated until a red pointer arm 41a overlies the intersection Y of the red half 36a of the shutter and the cut-out 39. The upper wedge ring is now in its final position. The switch 22 is next turned successively to positions F and A which respectively re-engage the lock 16 and disengage the hook 9 so that the superstructure may be slewed about a truly vertical axis.

Abstract: 818,661. Aerials; aerial coupling arrangements. GENERAL BRONZE CORPORATION. Oct. 17, 1957 [Oct. 22, 1956], No. 32450/57. Class 40 (7). Relates to aerial feed apparatus for use at centimetre wavelengths in which the feed is correctly matched over a wide range of frequency by the addition of suitable reactances. The apparatus comprises a length of waveguide 22, Fig. 1, mounted on the axis of a paraboloidal reflector 20 and terminated by a horn 24 positioned approximately at the focus of the reflector. Radio-frequency energy is radiated through the two curved branches of the horn, Fig. 3, on to the reflector. Two apertures 46, one only seen in Fig. 1, serve as the radiating elements and these give a capacitive loading to the horn. By the addition of inductive reactance this capacitive loading is neutralized and a good match effected. As shown, inductive irises 56, 58 are added, their position and size being so chosen that the desired characteristics are obtained. Unwanted effects due to energy returned from the reflector to the horn may be eliminated by use of a pair of circular plates 64, 66 mounted on the reflector such that the normals to the centres of the plates intersect at the horn and which are of such position and size that the energy reflected from them to the horn is equal in magnitude but opposite in phase to the energy reflected back from the parabola.
