Title: Apparatus for measuring the radial resilience of sealing rings
IPC: F16J15/3296
Filed: 1963-11-20
Abstract: 1,022,478. Testing shaft sealing rings. GOETZEWERKE FRIEDRICH GOETZE A.G. Nov. 20, 1963 [Nov. 20, 1962], No. 45874/63. Heading F2B.  The radial resilience of the sealing lip 2 of a shaft sealing ring 3 is determined by measuring the axial force required to insert a conical member 1 a predetermined distance into the ring. The ring 3 is supported in a rotatably mounted cup 7 and the member 1 is carried by a rod 19 connected to pins pivoted on beams 4, 4<SP>1</SP> journalled on pins fixed to a pillar 5. A counter-weight 24 is attached to the beams and a spring balance 9 is connected between a crossbar and a cord 21 which passes over a pulley 22 to a windlass 23 operated by a hand crank 10. In use, the member 1 is inserted into the ring 3 by operation of the crank 10 until a pointer 11 is on a given mark on a scale in the pillar 5 and the reading on the balance 9 is then a measure of the radial resilience of the lip 2. The cup may be rotated before the reading is taken and a number of such measurements may be made. The sealing lip may be lubricated with, for example, molybdenum disulphide, before a test is made. In a modification, Fig. 4 (not shown), both the member 1 and the ring 3 are rotatably and axially movable.

Title: Method as well as a system for determining the movement of a ship
IPC: G01C19/56
Filed: 1974-10-24
Abstract: 1484183 Ship movement monitor; indicating apparatus SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ BV 24 Oct 1974 46032/74 Headings G1G and G1J Movement of a ship is monitored by measuring at a location on the ship the longitudinal and lateral velocity at the location; measuring the rateof-turn of the ship about its vertical axis; computing the lateral speed of the ship at a chosen position from the measured lateral velocity and rate-of-turn and the longitudinal component of the distance between the location and the chosen position; and displaying the rate-of-turn, the longitudinal velocity and the computed lateral speed. In the embodiment described a dual-axis Doppler sonar measures the velocity components at an aeration-free location at the bottom of the ship, and a tuning-fork type sensor measures the rate-of-turn. An analogue computer converts the rate-of-turn measurement to equivalent lateral speed components at e.g. the bows, mid-ships and stern and algebraically adds these individually to the Doppler lateral speed measurement. The Fig. 3b device enables a selected one of the resultant absolute lateral speeds to be displayed by pointer 58 against a scale 64. Longitudinal velocity is displayed by pointer 56 against scale 62, and rate-ofturn by pointer 52. The intersection 60 of pointers 56, 58 indicates drift angle against scale 66. The ranges on scales 62, 64 are selectable by switch 68: switch 76 determines which of the three lateral speeds is displayed. In a modification the Doppler and turning-fork sensors are replaced by laser and gyroscope devices.

Title: Method and apparatus for measuring the current flowing in a workpiece
IPC: G01R1/20
Filed: 1976-11-05
Abstract: 1525310 Measuring current F W BELL Inc 5 Nov 1976 [8 March 1976] 46113/76 Heading G1U In a current measuring probe which has magnetically permeable core, remanent magnetism is removed by periodically, (e.g. just before a current measurement) inducing a damped oscillatory magnetic field in the core. The damped oscillation is generated by discharging a capacitor through a winding on the core, preferably while the current being measured is flowing and also preferably beginning with the opposite polarity field to the induced by the current being measured. Removal of the remanent magnetism enables the flux-sensitive device e.g. a Hall-plate detector to provide highly linear, repeatable results; to improve dynamic range and to enable the use of relatively low grade magnetic material for the core. The physical construction of the clamp-on probe is described, Figs. 1-2 (not shown).

Abstract: 1,167,745. Vehicle load-lifting platforms. M. D. ROBINSON. 21 Oct., 1966 [21 Oct., 1965], No. 47217/66. Heading B8E. A vehicle load-lifting platform has a deck D mounted by brackets G on an arm linkage C supported on a frame B under the bed 11 of the vehicle. The platform is raised by an hydraulic actuator E. In order to make the mechanism suitable for side loading of the vehicle the deck and linkage are foldable so that the mechanism can be raised to the stowed position, Fig. 4, wholly under the vehicle bed 11, thus avoiding projection from the side of the vehicle. The linkage C comprises pairs of compression arms 21, 22 hinged together at 23 and pairs of tension arms 24, 25 joined telescopically by a pin and slot connection 26, 27. The pairs of arms are spaced outwardly of the deck D and are mounted by vertically spaced pivots 30, 31 and 32, 33 on the frame B and brackets G respectively. A prop F supports the linkage from the ground with the arm 22 just clear thereof and a spring tension means H assists in foreshortening the linkage C. The brackets G are outboard of the deck D and have fingers to which the pivots 33 are secured spaced from the deck sufficiently to provide space for a pivot 32. To stow the mechanism from the Fig. 1 position the deck D and linkage C are progressively folded to the state of Fig. 4 and then the mechanism is raised to the stowed position by the actuator E. The outward spacing of the linkage C allow the deck D to be folded into it; the prop P holding the linkage sufficiently above the ground to prevent fouling. The spring means H assists folding and resists any tendency for the deck to fall during unfolding. A latch is provided to hold the mechanism raised if the actuator E droops.

The strip 14 is driven by a supply roll 15 to be taken up on a spindle 32, passing over the silver steel roller 18 and hinged plate 19 to be gripped by a metal roller 30 and a rubber roller 24 driven by an electric motor 26 thorugh a one-way clutch 25 which allows the roller 24 to be turned forwardly by a knurled knob 29. A belt 45 moves the sleeve 41 and stylus 43 towards a post 37 when the output shaft 50 of a magnetic clutch 49 is driven by an electric motor 46 coupled to a gear box 48 connected to the input shaft of the clutch 49. When the sleeve 41 depresses the pin 59 of a micro-switch 58 the clutch 49 is disengaged and a retracting band (56), Fig.3 (not shown) moves the belt 45 to return the sleeve 41 to its starting position. The switch 58 also releases the pressure of the plate 67 on the stylus 43. Upward displacement of the plate 67 is restricted by a bridge piece 71 held in slots 72 in side walls 61 by screws 73 and adjustable by a screw 74. The material of the strip 14 is made heat pressure-sensitive by sticking a layer of tough, black, heat-resistant paper to a paper base and superimposing a thin opaque film of cellulose and wax. The stylus 43 is made from electrical resistor wire suitably bent for contact with the paper and heated by passing an electric current therethrough under the control of a rheostat 84 having an adjusting screw 83. The film is eroded by melting and/or pressure which reduces its thickness and enhances the degree of blackness to be observed.
