Title: Gaging arrangement
IPC: G01B7/00
Filed: 1973-08-24
Abstract: 1425834 Monitoring dimensions electrically; measuring voltage peaks BENDIX CORP 24 Aug 1973 [5 Sept 1972] 40131/73 Headings G1N and G1U] The variations in the diameter of a shaft 12, Fig. 1, are measured by a group of transducers 10, the signals being analyzed at 16 to display on a columnar indicator 20 selected deviations from trueness. The dimensional signals in binary code from A/D converter 14 are fed via a multi-plexer 34, Fig. 2, controlled by sequencer 36 to memory devices 46-60. In one position of switches S1, S2, the varying signal from the first transducer 10 is compared at 64 (62) with the value stored in memory device 46 (54). If the input signal is greater (smaller) than the value in memory 46 (54) it replaces the existing store value. The other memory devices similarly store the maximum and minimum values of the signals from the other transducers 10. The difference between each pair of stored maximum and minimum values is determined at 76. The successive differences are multiplexed by unit 82 and fed to the indicator 20, enabling the appropriate one of a series of graded LED's 22 to emit. In the other position of  switches S1, S2, only memories 46, 54 are used to determine the overall maximum and minimum values and their difference is indicated at 20. A plurality of groups of four transducers 10 may be employed to determine the dimensional deviation of a longer surface.

Title: Synchronising a Data Receiver
IPC: H03L7/00
Filed: 1967-09-06
Abstract: 1,190,230. Automatic phase control. INTERNATIONAL BUSINESS MACHINES CORP. 6 Sept., 1967 [22 Sept., 1966], No. 40634/67. Heading H3A. A data receiver comprises : a first counter 12 for controlling the extraction of data from an input signal; a second counter 28 for counting the number of output digits from the first counter, which are produced between a selected portion of an item of data and a predetermined count of the first counter to produce a control signal representative of the phase difference between the first counter and the data; and means for varying the first control signal to synchronize it with the data. Assume initially that trigger 38 is in its reset state, and a logical " 1 " signal is present at input 10. Under these conditions the input signals to exclusive OR circuit 44 differ, and a " 1 " signal is fed on line 44A to enable AND gate 46. Counter 28 will now advance one count for each TPA input pulse. At the same time, counter 12 advances one count at each TPC pulse until a count of eight is reached. When this occurs, the output on line 14 enables AND gate 42 so that the next TPD pulse causes trigger 38 to switch to its " 1 state. The inputs to the exclusive OR 44 now become equal and the resulting " 0 " output inhibits gate 46 to stop the count of counter 28. The signals on lines 38-1 and 40-0 are now both " 1 " and AND gate 50 is thus enabled so that the next TPC pulse produces a " 1 " output from gate 50 to reset counter 28. With the circuit in its " coarse " adjustment state, a potential is applied to line 30, so that the output from gate 50 also enables AND gates 54, 58. If the count of counter 28 is less than 13 AND gate 58 produces an output which triggers RETARD trigger 36 to feed a " 1 " output to AND gates 65, 84. In the " coarse " control condition, only AND gate 65 is enabled, and counter 12 resets at a count of four. In a similar manner a count of greater than twenty in counter 28 actuates ADVANCE circuit 34 and resets counter 12 at a count of twelve. When the circuit is switched to " fine " adjustment a potential is applied to line 80 instead of line 30. Under the condition the triggers 34, 36 are actuated at counts of greater than sixteen and the counter 12 is reset at fifteen and one. Adjustment continues until a count of eight in counter 12 is in phase with the received signal.

Abstract: 1,062,429. Trimming piastic moulded articles. F. W. ARMYTAGE. Nov. 12, 1965 [Oct. 7, 1964], No. 40950/64. Heading B5A. Surplus material is cut from the top of moulded bottles &c. by a rotary head 3, 4 driven by a shaft 1 and carrying an axially offset spindle 7 on which a cutter blade 10 is mounted, the spindle being rotatable about its axis and vertically reciprocable relative the head. The spindle is housed in a sleeve 6, and s grooved at 12 to receive trunnions 13 of a lever 16 pivoted at 17 to a bracket 18, and the lever carries a roller 19 engaging a cam 20 freely rotatable about the sleeve. A spring 14 holds the roller in contact with the cam and a spring 30, Fig. 2 (not shown), holds the cam in an initial position in which the spindle is in its uppermost, inoperative position. A rod 27 extends from the cam boss and is grooved to receive the end of a pin 29 fixed to the spindle. When a bottle &c. is located below and axially aligned with the head, the head is rotated, but the cam, due to centrifugal forces acting on it, swings around the spindle housing and rooks the lever 16 which lowers the cutter spindle and, at a predetermined time, the downward movement of the pin 29 in its groove causes the spindle to turn about its axis and swing the cutter blade inwards to effect the cutting operation. When the drive is stopped abruptly the cam rotates in the opposite direction and the blade spindle is returned to its initial position.

Abstract: 1329653 Programme control of machine tools BENDIX CORP 13 Sept 1971 [21 Sept 1970] 42526/71 Heading G3N A numerical control system for a machine having an element movable along at least two areas includes a rapid tool retractor subsystem for withdrawing a tool from a workpiece at the end of a prescribed operation. As shown, a two axis lathe 12 is controlled by commands from a tape 18 read by an eight channel reader 20. The x, z axes positions after being sequentially read are decoded by a register 22 and fed to storage registers 24, 26. Additionally x, z advance per spindle revolution are stored in registers 25, 27. The stored position values are transferred to interpolators 28, 30, which provide command pulses at rates determined by interpolators 31, 33 responsive to the registers 25, 27 to servos 14, 16 through a pulse rate control 34. For rapid retraction of the tool the X, Z axis identity signals from register 22 set flip-flops 50, 52 which apply input signals to gates 44, 46 Additional identity signal inputs to gates 44, 46 are received from comparators 40, 42 which are high when the differences between actual and command positions are zero. The gates 44, 46 are enabled by a signal from a thread-cutting unit 54 and the flip-flops 50, 52 are reset by coincidence or X, Z identity signals at the inputs of a gate 53. When a final X or Z co-ordinate position is reached, gate 44 or 46 produces a high output which through an inclusive OR gate 48, actuates the pulse rate control 34 to activate a line 34 or 38 so that the tool is displaced along the Z or X axis at the maximum traverse rate.

Title: Comparison network
IPC: H04L25/22
Filed: 1964-10-20
Abstract: 1,076,859. Transistor switching circuits. RADIATION Inc. Oct. 20, 1964 [Jan. 7, 1964], No. 42797/64. Headings H3T and H4P. The magnitudes of currents in two channels are compared by means of a transistor across each channel (without any additional power supply), the base of each transistor being supplied with a fraction of the current from the other channel so that by regenerative action only one transistor conducts at a time; current responsive loads across one or both channels are thus energized if the corresponding transistor is not conducting. In the Figure the invention is applied to a telegraphy system in which one channel transmits mark and space signals and the other channel transmits a reference current of half the amplitude of the mark pulses. At the receiving end of the lines 12, 13 each channel is shunted by a relay 16, 17 (electromagnetic or solid state), transistor 43, 43<SP>1</SP> and voltage divider 41, 42, 411, 42<SP>1</SP> (which may be variable). The voltage at the divider tap is applied to the base of the transistor in the opposite channel via a differentiating network 45, 46, 45<SP>1</SP>, 46<SP>1</SP>. During a space period (say on line 13), transistor 43 is cut off while 43<SP>1</SP> is fully conducting; relay 16 is therefore energized so that positive current flows from 21 to the receiver coil 23, while relay 17 is shortcircuited by transistor 43<SP>1</SP>. When a mark arrives, the leading edge turns on 43 to deenergize relay 16; at the same time the voltage across the divider 41, 42 falls due to the current drain of the transistor 43, and by regenerative action 43<SP>1</SP> is cut off and 43 conducts fully. Relay 17 is then operated to supply negative current to the coil 23. At the beginning of a space the reverse operation occurs. The invention is also applicable to systems using a simple on/off relay at 23 instead of a polar relay, in which case relay 16 and supply 21 are omitted. Relay 25 is used to open the circuit when no transition information is present on the lines 12 and 13.
