Abstract: 1335993 Position finding MATISA MATERIEL INDUSTRIELE SA 10 Dec 1970 [26 Dec 1969] 58642/70 Heading H4D Apparatus for determining the position of a point P relative to at least two other points N 1 , N 2  each provided with a point light source, for use in aligning railway tracks, comprises two identical assemblies 2, 3 mounted one on each side of a motor 5. Each assembly comprises a fixed detector 9 having four solar detector cells 12a, 13a, 14a, 15a, a fixed screen 8 having two perpendicular slits 12-13 and 14-15, and a screen 7, rotated by motor 5, which carries one or two lenses 10, 11, the screen 8 being in the focal plane of the lenses 10, 11. If two light sources N 1 , N 2  are used with each screen 7 having one lens, a rotating image of the respective light source is formed on screen 8 and the angle between the beam from the respective light source and the axis XX<SP>1</SP> of the apparatus is calculated as a function of the difference of the time for the image to pass from half-slit 12 to half-slit 13 and the time for the image to return from half-slit 13 to half-slit 12. If the angles calculated by the two assemblies 2, 3 for the light sources at N 1 , N 2  are the same it means that the points N, PN 2  are aligned, and the difference between the angles of N 1 , N 2  is a measure of the misalignment of point P from the straight line joining N 1 , N 2  irrespective of the alignment of axis XX<SP>1</SP>. In an alternative embodiment for use with three light sources at N 1  on one side of the apparatus, and N 2  and N 3  on the other side of the apparatus with the sources at N 1  and N 2  producing vertically polarized light, and the source at N 3  producing horizontally polarized light, two polarized lenses 10, 11 are provided in the screen 7, with their polarization angles perpendicular, so that every time the source at N 2  gives a pulse of light through lens 10, the source at N 3  gives a pulse of light through lens 11. This allows the position of point P to be determined in three dimensions without having to know the orientation of axis XX<SP>1</SP>. A revolution counter selector 17 may be employed to separate the incoming pulses, and the polarized sources and lenses may be inclined at 45 degrees to the vertical to reduce the effect of light reflected from, e.g. the rails of railway tracks.

Apparatus, e.g. for machining turbine and compressor blades, comprises a plurality of work stations 1, 8 for performing machining operations, e.g. vertical broaching, on a workpiece which is carried on a work-holder to each station in turn by endless conveying means 3, 10, the stations are arranged in two groups 1 and 8 in series in a single line adjacent one side of said conveying means, and a transfer means 19, 20 located between the last station in the first group and the first station in the second group for removing a workpiece from a work-holder which has been conveyed past said first group 1, rotating it through 180 degrees and loading it into another work-holder on said conveying means for passage past said second group 8. The conveying means comprises two conveyers 3, 10 in line and each adjacent its respective work station group 1, 8. Hydraulic rams 4, 11 at each station push a workpiece from its work-holder on the conveyer on to a work fixture 2, 9 where the machining operation takes place. Adjacent to each conveyer 3, 10, and at a lower level relative thereto, is a storage conveyer 7, 14 for supplying empty work-holders at the input end of conveyers 3, 10 and removing them at their output ends by means of transfer devices 5, 6 and 12, 13. Workpieces are initially mounted on work-holders at transfer device 5. Gates 15 along the conveyers 3, 10 stop a work-holder at each station. In the example described turbine blades are encapsulated in a rectangular block of stable low melting point alloy. At the 180 degree transfer means 19, 20 a workpiece is pushed from its work-holder on to a fixture 17 where it is grabbed by hydraulically operated jaws carried by a slidable and rotatable part of a turntable 19. This is also lowered to the level of a further conveyer 20 which receives the workpiece suitably orientated. The conveyer 20 includes a number of gates to control the movement of a workpiece towards a vertically movable take-off point from where the work piece is pushed on to a fixture 18. A buffer store may be provided alongside the conveyer 20 into which workpieces may be pushed. Movements are actuated by hydraulic rams with suitably arranged trip switches. The turntable 19 is moved and rotated by hydraulically operated rack and pinion drive. The jaws are operated by single oscillating vane actuator.

A vehicle approaching the crossover on wheel tracks 24 has a guide roller engaged in grooved track 26 if it has to move to the right on grooved track 34 or engaged in grooved track 29 if it has to cross over to the left track. The two wheel tracks 24, 24<SP>1</SP> are arranged to run parallel in approach to the crossover so that extension 20<SP>1</SP> on a vehicle on the right hand track 24 and taking the crossover will engage a part of another vehicle if present on wheel track 24<SP>1</SP> approaching the junction. This engagement rocks the bar 17 so that the vehicle is then routed safely to the right end track away from a possible collision at the crossover. Similarly, the vehicle on track 24<SP>1</SP> if set to cross over will be actuated to follow the left track to avoid the collision. For routing a vehicle from a station on a shunt track on a main loop to another station on a shunt track on the same loop the vehicle carries three counters, the first indicating the number of the desired station, the second indicating initially the number of the departure station and this is stepped forward by a pulse received from a track contact as the vehicle passes the entry to each succeeding station junction and the third indicating the difference. When this is zero solenoid 19 or the like is operated to rock the bar and route the vehicle over the associated junction to the station shunt track. Track loop arrangements can be provided for routing vehicles, which are diverted at crossovers &c. to avoid collision, back on to their route track.
