Title: Method and apparatus for producing digital contour movement
IPC: G05B19/40
Filed: 1969-03-11
Abstract: 1,254,333. Programmed control of machine tools. SUPERIOR ELECTRIC CO. March 11, 1969 [April 4, 1968], No. 12682/69. Heading G3N. In an apparatus for incremental movement along a desired path the co-ordinate stepping motors are controlled in response to an interpolating process wherein, for a linear movement, the total deviation, defined as to the number of X co-ordinate steps times the negative value of a Y step length plus the number of Y co-ordinate steps times the positive value of the X step length, is interrogated after each step and when the deviation is O or positive an X step is taken and when negative a Y step. For an arc, the X and Y coordinates of the centre of the circle of which the arc is part are used to derive, by right triangle relationships, the deviation in terms of the square of the arc radius less the square of the hypotenuse to the stepped position. The next movement is an X step if the deviation is O or positive and a Y step when negative. As shown, the input from a punched tape reader 101, or manually set dials, is fed to a storage unit 102, which includes a block 102a for step change #X in co-ordinate X and its sign, a block 102b for the corresponding step change #Y, a block 102c for the X co-ordinate displacement of the centre of the circular arc from the start of the arc and its sign and 102d is the corresponding Y co-ordinate displacement for which the sign is not stored since it is derived from the contents of blocks 102a-c. Upon a command from a control unit 111 signals from storage units 102a-d are fed by a transfer unit 103 into registers 104-107, comprising up and down counters. The logic in control unit 112 monitors the contents of the registers 104-107 and energizes X, Y reversible stepping motors 110, 111 with pulses derived from an oscillator 109. On completion of a step the control 112 updates the registors 104-107 and calculates the error, which is stored in a register 108, and determines the co-ordinate direction in which the next step is taken.

Title: Apparatus for dispensing and weighing a number of constituents for a charge, more particularly the preparation of concrete
IPC: B28C7/04
Filed: 1961-04-10
Abstract: 986,884. Weighing-apparatus. ARBAU BAUGERATE G.m.b.H. April 10, 1961 [April 9, 1960], No. 12869/61. Heading G1W. Apparatus for dispensing and weighing a plurality of constituents for a charge, e.g. of concrete, which are supplied seriatim to a belt conveyer which co-operates with a weigher and are weighed while on the belt, is characterized in that the belt conveyer 1 and a receptacle 22 for receiving the material delivered by the continuously moving belt conveyer are both mounted on the weigher 16, whereby the weigher will weight the total amount of material in the receptacle and on the belt conveyer. The bottom of the weighing receptacle 22 is closed by a shutter 24 which is operated by an automatically controlled motor 25. The control is such that the shutter 24 closes only when the entire charge has passed through the receptacle 22, but the operation is not dependent on the accumulation of the charge in the receptacle since the indicator 13 responds also to the weight of material on the moving belt, simultaneously with the weight of material in the receptacle, and material is fed to the belt in accordance with the working of the indicator and the shutter 24 opens as soon as the total weight has been fed to the belt 1, i.e. it may open while the remainder of the charge is still on the belt. The different aggregates to be included in the mix are in storage bins 26, each with a discharge shutter 27 controlled from the indicator 13. The conveyer belt 1 rests on supports 2 and 4. The support 2, at the delivery end of the belt 1, rests directly on the platform 3 of the weighing apparatus. The supports 4, at intervals along the belt, rest on arms 5 of bell cranks, the other arms of which are connected to a draw rod 7. The end of the draw rod is coupled to the lower arm 8 of a bell crank 8, 9 which is linked with the weighing mechanism. Thus a depression of the belt 1 produces a pull in the rod 7 which, through the mechanism, causes a response in the indicator 13. The draw rod 7 is supported by guides 19 and can be adjusted in length by couplings 20. The linkage is steadied against vibration by arms which are pivoted at 18, the connections being loose to prevent jamming. A lever 12 in the weighing mechanism carries a movable weight 21 to give tare adjustment. In a modification the weighing conveyer is reversible with a weighing receptacle at each end, and, in another modification, the conveyer may comprise a series of separate belts. The weighing means may be mounted on wheels and run beneath the belt. The weighing conveyer may also be below ground level.
