Title: Arrangements for Calculating Datum Points of a Curve defined by a Model
IPC: G05B19/42
Filed: 1968-01-11
Abstract: 1,173,396. Digital electric calculators. SIE MENS A.G. 11 Jan., 1968 [11 Jan., 1967], No. 1744/68. Heading G4A. A circuit arrangement for use with a model scanning apparatus for calculating co-ordinates of datum points of a curve defined by a model scanned by the scanning apparatus comprises input means receiving from a scanning apparatus signals which are measures of the co-ordinate values of a curve of a scanned model, means storing the calculated co-ordinate values of datum points, computer means extrapolating a curve of predetermined function from the most recently calculated datum point, means forming the difference between the input values and the extrapolated values, means sensing when the difference between the input and extrapolated values has reached a predetermined level, and means responsive to the sensing means to cause the then existing input co-ordinate values to be introduced into the storage means as a new datum point. A tracer following a model feeds data indicating, for instance, the Y, Z co-ordinates 11, 12 to stores 13, 14 of a calculator. This can represent datum point P 1  (Y 1 , Z 1 ) the value of which is also stored in registers 15, 16. As the tracer progresses the values of Y and Z alter and the differences Y-Y 1 , Z-Z 1  appear at the output of difference register 17, 18. The computer sections 19, 20 extrapolate in dependence on the difference between the last two datum points (Y 1 -Y 0 , Z 1 -Z 0 ) along a straight line to produce a value Y f , Zf in synchronism with the reading of the corresponding location on the model. The value Y-Yf appears at the output of the difference forming circuit 23, 24. When the difference reaches a predetermined value the existing Z and Y values are fed into stores 26, 27 as new datum points, Y 2 , Z 2  the new values Y 2 -Y 1 , Z 2 -Z 1 , for extrapolators 19, 20 are obtained from the difference registers 17, 18 and the stores 15, 16 are erased and the new values inserted. The procedure can obtain datum points used in punched tape for programmed machine control. Three interpolator sections can be used for three-dimensional scanning. As shown scanning is performed for a predetermined X value.

Title: Improvements in and relating to Fluid Pressure Braking Apparatus.
Inventor: TURNER WALTER VICTOR
IPC: B60T13/68
Filed: 1917-02-27
Abstract: 110,740. Turner, W. V. Oct. 21, 1916, [Convention date]. Fluid-pressure.-In an electro-pneumatic brake system for double-ended cars, the circuit of a release magnet is completed in the " handle-off " position of the driver's valve and switch, so as to keep the brakes on while the driver is changing ends and release is automatically effected when the valve is turned to running position at the opposite end of the car. The release may be effected by a pneumatically actuated switch interposed in the release magnet circuit. The equipment shown comprises the valve mechanism 1 having release, service, and emergency magnets 2, 3, 4, and an automatic train pipe 6 controlled by a combined switch and valve device 7 arranged at each end of the car. The release magnet 2 closes and opens the brake cylinder exhaust according as it is energized or de-energized. The penumatically controlled switch 11 is interposed at each end of the car in the release magnet circuit and comprises a piston 15 carrying contacts 16 for engagement with fixed contacts 17. A piston slide valve 20 controlling the admission of pressure air beneath the switch piston 15 is itself controlled by differences of pressure in the equalizing reservoir 26, and the train pipe 6, the reservoir being connected to chamber 19 by passages 24, 25, and the train pipe to chamber 21 by passage 23. In the normal position shown, these pressures are equal and the switch piston cylinder 13 is open to exhaust port 30 by passage 28 and valve cavity 29 so that the switch 16, 17 is closed by spring 31. Before leaving one end of the car, the driver applies the brakes and turns the handle to " off " position so that the release train wire 8 at that end is connected to the battery and the release magnet 2 is energized. In applying the brakes, the equalizing reservoir reduces equally with the train-pipe pressure and the switch 16, 17 remains closed. When the handle is turned to running position at the opposite end of the car, the trainpipe is recharged but the equalizing reservoir pressure at the non-operating end remains reduced since this reservoir is cut off from the train-pipe in the " handle off " position of the valve 7. The slide valve 20, 21 therefore moves to the right uncovering the passage 34 so as to admit air from the train-pipe beneath the switch piston 15, thereby disengaging the contacts 16, 17 and releasing the brakes. The equalizing reservoir is at the same time connected by cavity 29 and port 24<1> to exhaust port 30 to prevent possible building up of pressure in this reservoir.
