Title: Improvements in or relating to automatic levelling suspensions for vehicles
Inventor: HEISS JOHN P
IPC: B60G17/048
Filed: 1957-11-11
Abstract: 865,359. Road vehicle spring suspensions; springs. THOMPSON PRODUCTS Inc. Nov. 11, 1957, No. 35100/57. Classes 108(2) and 108(3). In a continuous-flow automatic levelling system for vehicles a hydropneumatic strut 17, Fig. 1, is pivoted to a rear axle housing 14 at joint 18 and to a plane member 10 at joint 19. In the independent suspension of the front wheels the strut is mounted between a pair of lower wishbones and the frame 10. Pressurized hydraulic fluid from a pump 21 is supplied to the strut 17 through a conduit 23. Fluid leaves the strut through a conduit 24 and passes to a reservoir 25 through a lockout valve 22. Member 32, Fig. 4, slides in a member 30 to pump fluid to and from chamber 38 through damping orifices 41, 39 and 40. The pneumatic spring is formed by an outer housing 34 and a bladder member 35 between which in chamber 20 is air under pressure. As fluid enters through the conduit 23 it passes through a check valve 45, conduit 46 and past needle valve 47 through orifice 48 and into chamber 33. Needle 47 may be biased by a spring 52, bent, or provided with a bush to damp out oscillations which cause noisy operation. If a bush is provided it must be perforated or the needle fluted to provide a path for fluid. Fluid continuously leaves chamber 33 through a calibrated orifice 60, which contains a filter, and a check valve 68. Conduits 23, 24 may be provided with heat exchanger elements to warm or cool the circulating fluid. To prevent buckling of needle 47 by rapid oscillations a by-pass 71 is provided between chambers 70 and 33. A check valve 72 closes the by-pass except when a high pressure is built up in conduit 46. Spherical portion 80, 80a, of joint 18 is held against a liner 84, of nylon or polyethylene, by socket member 81. The joint at the top of the strut has a conical rubber mount 90 with an outer metal shell 93 which is held in position within the frame 10 by a clip 95. An inner sleeve 98 of the mount 90 is secured to member 32 by snap ring 97. The conical shape of the mount 90 and the shape of backing plate 99 provide a variable-rate spring. Lockout valve 22, Fig. 1, prevents collapse of the struts when the supply of pressure fluid fails by closing the outlet conduits 24. Plunger 22a is held in the position shown in Fig. 1, by pressure applied to chamber 22c through conduit 112. When the pressure drops, plunger 22a is raised by spring 22b, thus moving passage 22d out of alignment with conduit 24 to prevent escape of fluid from the struts. Check valve 115 prevents opeing of lockout valve 22 by accidental leakage of pressure from chambers 33 past the individual check valves 45.

Abstract: 1,199,565. Measuring oxygen content, electrochemically. BAIRD & TATLOCK (LONDON) Ltd. Aug.3, 1967 [Aug.9, 1966], No.35629/66. Heading G1N. The concentration of a substance in solution is measured by treating the solution with a reagent that reacts with the substance to vary the concentration of oxygen in the solution in proportion to the initial concentration of the substance and measuring the change or rate of change in the oxygen concentration using an oxygen electrode. As described with reference to Fig. 1, the reagent is introduced into chamber 1 through inlet 3, and may be pumped continuously through the cell for initially washing the chamber. The solution under test is added through an injecting lance 13. An electrolytic cell for measuring oxygen concentration comprising a platinum electrode 11, glass coated at 10, and silver/silver chloride reference anode 12 in a buffer solution containing phosphate and chloride ions is separated from the sample by an oxygen-permeable membrane 7. Stirring is by a magnet 15 on a plastic covered magnetizable slug 17. In an alternative arrangement, the membrane 7 is omitted so that the oxygen electrode is in direct contact with the solution under test. In this case the electrode is vibrated or rotated to maintain a continuously renewed contact between it and the surrounding liquid. Many examples of substances that can be measured and appropriate reagents are given. Glucose can be measured, using a 1% glucose oxidase solution saturated with air as the reagent, the slope of the recorded oxygen concentration being a measure of the concentration of glucose in the sample. If desired, a 0À1% alcohol or peroxidase and an aromatic amine or phenol may be added to the reagent to preserve stoichiometry in the presence of catalase. Galactoze, uric acid, ascorbic acid (vitamin C), amino acid, amine, diamine, xanthine, aldehyde, lipid and phenolic oxidases can be used as reagents or may be measured themselves. In general, any reaction which produces a molecule for which an oxidase or dehydrogenase exists can be measured by measuring oxygen consumption. Hydrogen peroxide can be measured, by catalytic conversion to water and oxygen. Catalase can be measured by measuring the rate of oxygen liberation from hydrogen peroxide or an alkyl hydroperoxide.

[Class 120 (ii).] Electric flyer motors 1 are driven by three-phase current from mains 2 through resistances 4, 5, so that, on closing the switch 3, the current to the flyer motors 1 and to the motor 6 driving the rollers of the drawing head is such that the turning moment of the motors is only sufficient to tension the threads without starting the bobbins revolving. The simultaneous closing of the contact 9 energizes magnetic switches 10, 12, controlled by hydraulic or pneumatic delay mechanism 11, 13, such that the contact 7, which by shorting the resistance 4, starts the motors 1 revolving slowly and the motor 6 at full speed, is not closed until after the threads have been tensioned, while the contact 8, which shorts the resistance 5 and accelerates the motors 1 to full speed, closes after a further delay. A switch 14 allows the operator to prevent the closing of switches 7, 8 if a bobbin revolves immediately switch 3 is closed, indicating a broken thread. Transformers may be used in place of resistances for lowering the turning moment.

Abstract: 1475162 Protective devices TOKYO ELECTRIC POWER CO Inc and MEIDENSHA KK 14 Aug 1974 [20 Aug 1973 5 Dec 1973] 35844/74 Heading H2K A method of detecting a short circuit in a cylindrical current carrying winding 20 of a magnetic circuit a transformer, the winding being coaxial with a magnetic core 28 and in a cylindrical housing 30 comprises detecting with an electrically conductive element 32 asymmetry in the distribution of leakage flux of the magnetic circuit about a point of symmetry of the winding, by producing across the element a voltage which is a measure of this asymmetry, and feeding this voltage to a level detector and switching means to produce an output signal when this voltage exceeds an adjustable predetermined level. Asymmetry in either the radial component or axial component of the leakage flux may be detected. The electrically conductive element may be a helically coiled conductor 32<SP>1</SP> mounted on an outer surface of the magnetic core 28 of the transformer and surrounded by the primary windings 20 or mounted on the inner surface of a side wall 30a of the transformer housing and so positioned relative to the transformer primary that the normally symmetrical distribution of leakage flux causes equal and opposite voltages which cancel in the conductor 32 but an asymmetrical distribution B2 of leakage flux due to a shortcircuit section 20a gives rise to a resultant voltage in the conductor which is fed to the level detector. In the case where the short circuited section is symmetrically placed in the primary however the leakage flux will still have a symmetrical distribution and to deal with this case a further embodiment is described, Fig. 8, wherein a pair of helically coiled conductors 48, 50, 48<SP>1</SP>, 50<SP>1</SP> are mounted on the transformer core 28 and housing wall 30a in addition to the first conductor 32, 32<SP>1</SP>, adjacent to and symmetrically on either side of the lengthwise mid point of the primary winding 20, their outputs also being fed to the level detector. As an alternative to the helically coiled conductors, field sensitive semi-conductor elements such as Hall effect or magneto-resistance effect devices are used.
