Abstract: 1280341 Position measuring apparatus AUTOMATIC RADIO MFG CO Inc 26 Feb 1970 [13 March 1969] 13341/69 Heading G1N [Also in Divisions G3 and H1] In order to measure the position of a movable point of contact between a probe and a surface of uniform resistivity having a pair of electrodes spaced apart thereon the current flowing through one of the electrodes when a current source is connected to the probe is measured, the current being dependent upon the position of the point relative to the electrode. The arrangement of Fig.2 enables the X, Y co-ordinates of the point of contact of probe 6 on sheet 1 of resistive material to be measured. Diodes 21 are each connected to a respective point of contact on sheet 1, i.e. electrodes 22, 23, 24, 25. In operation transistors T 1 , T 2  are rendered conductive and transistors T 3 , T 4  rendered non-conductive by pulses from sources 26, 27 so that current flows from source 6a, through probe 6 resistive sheet 1 diodes 21 and transistors T 1 , T 2 . An output signal proportional to the position of probe 6 from electrode 22 is derived from resistor R 2  During the next period transistors T 3 , T 4  conduct and transistors T 1 , T 2  are non-conducting, an output signal representative of the vertical displacement of probe 6 from electrode 25 being derived from resistor R 3 . If the current I from source 6a is not constant the ratio of the current through the electrode and I is measured to give the displacement. If source 6a is a pulse or alternating current the probe 6 may be capacitively coupled to the sheet 1. In the arrangement of Fig.1 (not shown) the electrodes are in the form of strips along the edges of the sheets. The transistors may be omitted if the diodes of the pairs are oppositely poled. The probe 6 may be in the form of an electron beam, Fig.4, in which case the sheet 1 may be formed of indium oxide and/or tin oxide on the inner surface of a C.R.T. or alternatively formed of aluminium deposited on the phosphor coating of the C.R.T. Comparator 30 compares the measured co-ordinates of the beam point on the C.R.T. with reference co-ordinates represented by deflection signals on lines 32. A correction signal, if there is any difference, being applied to the beam deflection control to bring the beam back to the desired point.

Abstract: 134,608. James, R. W., (Babb, M. J.). Nov. 4, 1918. Teeth, artificial.-Relates to articulators of the type in which the upper model-holders may be oscillated about an axis inclined with respect to the occlusal plane, and consists in the provision of means whereby the angle of the axis of oscillation may be varied about a point above the central incisai point, and of means for lineal adjustment of the model-holders normal to the occlusal plane. The apparatus comprises a base carrying a block 11 in which the lower-jaw model-holder 7 slides longitudinally and is secured by a screw 12. The usual hinge 21 is arranged in the occlusal plane 31 and comprises a lower member having a screwthreaded downward projection 15 normally abutting against an oppositely-threaded upward projection 14 from the block 11 and connected thereto by a threaded sleeve 22, rotation of which gives vertical adjustment of the hinge. This adjustment is limited by slots 20 in side plates 17 connected to the block 11, and through which the hinge-pin passes. The upper member of the hinge is formed with stop-lugs 27, 28 to engage a stop 30 on the lower member, and with a post 25 fitting within a socket 33 in a support 32, which is forked at its upper end 40 and fitted with trunnions 41 supporting a rectangular yoke 42. The yoke 42 is adjustable about the trunnions 41 by means of a graduated sector 43 and set-screw 49, and carries by means of trunnions 52 an inner yoke 53. The yoke 53 is provided with a shaft co-axial with the trunnions 41 and pivotally supporting a hanger 56 carrying the upper model-holder 77. The hanger 56 is restored to a vertical position, or adjustment of the yoke 42, by moving it along a sector 60 attached to the inner yoke 53. Means are provided for vertical and longitudinal adjustment of the modelholder 77 with regard to the hanger 56. The models are secured to their respective holders by mountings 8, 80 secured by screws 9, 81 and dowel pins 10, 82.

Apparatus for recording operational and working times of a vehicle driver comprises a writing arm 7 and several driving coils 3, 4, 5 selectively energized by an electrical pulse generator 1 individually or in pairs to act on a rotatable armature 18 coupled to the arm 7 which it drives perpendicularly to the direction of movement of a time driven record surface so as to perform writing movements limited in such a way as to distinguish different elapsed-time periods. In order to record the working or driving time (F), stand-by time (A) and pauses, (P) of two motor vehicle drivers I, II, two writing arms 7, 6 are pivoted on shafts 10, 9 and provided with spring mounted stylii 12, 11 and pins 14, 15 urged into contact with a cam 16 by a spring 13, the cam 16 being mounted on the shaft 17 of the two-pole magnetic armature 18 and having several concentric steps arranged symmetrically about a central position. The stylus 12 remains in one zero position so long as coil 3 is not energized and stylus 11 in another so long as coil 5 is not energized, while energization of the coils 3 and 5 respectively cause the cam to turn in one direction or the other, through 45 degrees if coil 4 is also energized, otherwise through 90 degrees. To record bar diagrams representing different categories of elapsed time the drivers select their appropriate categories by setting individual switches 19, 20 Fig. 3, (an interlock preventing both being set to drive poisition (F)) and an astable multi-vibrator produces pulses alternately at terminals AI, All for energizing the coils 3, 4 and 5 as required to cause the stylii 12, 11 to trace broad or narrow bars or "zero" lines as appropriate to represent working or stand-by time or pauses for each driver.

Title: Process of recovering cassiterite and other tin oxides from ores or other materials containing same
IPC: B03D1/06
Filed: 1966-03-29
Abstract: SnO2 e.g. cassiterite, is recovered from minerals by removing colloidal slimes from the mineral, subjecting the decolloided material to froth floatation in the presence of a mineral acid and a petroleum sulphonate and recovering SnO2 as a froth concentrate.  The colloidal slimes may be removed by a cyclone washing circuit into which may be introduced an alkali metal hydroxide, carbonate or silicate as a dispersing agent.  The mineral may be Bolivian ores or cassiterite from the Renison district of Tasmania which has a grain size of -325 mesh Tyler series.  The mineral may be subjected to conventional sulphide extraction, e.g. froth floatation with a xanthate, and crushed and ground prior to the above process.  The mineral may be pre-conditioned to a pH of 1.0 to 3.5 with the mineral acid, e.g. H2SO4, and/or the petroleum sulphonate, and crushed to -48 mesh.

In a device for controlling the counterclockwise return movement, under spring action, of a rotatable member 1 which is intermittently rotated clockwise by a continuously rotating gear segment 4 engaging a segment 3 on the member 1, the gear segments 3, 4 have respectively fixed thereon a wedge 5 and a wedge-like control cam 6. As the gear segments disengage after each clockwise movement of the member 1, the highest part of the cam 6 engages the lowest part of the wedge 5, as shown, so that continued counterclockwise rotation of the cam 6 allows the wedge 5 to slip past the cam 6, the member 1 being thus returned counterclockwise by its spring at a rate controlled by the rotation of the cam 6. The Provisional Specification describes the device in combination with the apparatus for forming a composite sheet disclosed in the main Specification. Specification 780,210 is referred to.
