Title: Apparatus for controlling an electric arc
IPC: B23K9/067
Filed: 1970-11-12
Abstract: 1329438 Supply systems for arc welding A O SMITH CORP 12 Nov 1970 [13 Nov 1969] 53958/70 Heading H2H A supply system for an arc welding gun 1 comprises a switch 13, a coil 19 which generates a magnetic field when arc current flows through the coil, a coil 18 which generates a magnetic field when a starting current flows therethrough from a source 16 in response to short circuiting of the gun to earth and circuitry which enables current to be supplied to the gun from a source 3 when one or both magnetic fields are present. Initially, when the gun is short circuited to the workpiece 5, the low voltage D.C. source 16, which includes a step down transformer supplied by the source 3, causes a current to flow through the coils 18, 19 thereby closing contacts 15 of the reed switch 13 and energizing a relay coil 14. Contacts 12-1, 12-2 of the relay are therefore closed to provide welding current to the gun and to supply a drive motor 10 which feeds a consumable electrode 6. A capacitor 20 holds the current in the coil 18 until the weld current builds up sufficiently for the coil 19 to hold the switch 13 closed. The flow of weld current back biases a diode connected between the coils to block the output of the source 16. When the gun is withdrawn from the workpiece the contacts 15 are opened thus opening the contacts 21-1, 12-2 to disconnect the source 3. The coil 14 may control relays to connect the source 3 to other devices which provide a gas supply to the arc or coolant to the gun and the source 3 may be A.C. or D.C.

Abstract: 1376596 Coin freed electric meters ALBERICE ELECTRICAL Ltd 1 Nov 1971 [17 Nov 1970] 54664/70 Heading G4V A coin freed mechanism for controlling the supply of electricity comprises an electric meter 10, including a motor and indicating means driven by the motor for indicating the total amount of electricity consumed, a coin receiving device 14, a rotatable control member 18 coupled by way of gears to the meter motor and said device so that the insertion of a coin in the device enables the control member to be rotated in a first direction whilst consumption of electricity causes the member to be rotated in the opposite direction, and a switch 16 controlled by said control member for selectively making and breaking the electricity supply. The control member 18 is fixed to a shaft 42 which carries a pinion 34 and indicator 64 (for unconsumed quantity), the pinion 34 and gears 30, 32, 36 and 38 forming a differential of standard type. The coin receiving drum is also connected by a linkage 66 to indicators 68 for credit value of coins inserted. Switches.-When the mechanism is out of credit finger 44a of spring lever 44 will be opposite cut out 18a in the control member 18 and the switch contacts will be open. On insertion of a coin and rotation of drum 14, gear wheel 22 rotates, driving control member 18 clockwise and a pinion 60 fixed to cam 56 anticlockwise. During rotation of cam 60 arm 58 is depressed closing the switch contacts and a step 56a on the cam contacts shoulder 50a on lever 50 tending to rotate it clockwise. Movement of lever 50 is blocked however by a pin 54 on lever 44 since finger 44a is no longer opposite the cut-out in the control member, and the switch is thereby latched in the closed position. Pinion 60 has some teeth missing allowing further insertion of coinage and rotation of gear-wheel 22. On consumption of the prepaid quantity lever 44 and hence lever 50 are freed for rotation, and cam 56 is returned to its rest position by springs 58c and 62. Modifications of the switch arrangement are described in which the movable contact is carried by a spring pivoted arm engaged by arm 58, and the finger 44a carries a slidable sleeve to ensure that the finger will effectively engage the control member on insertion of the first coin.

Title: Analogue divided with digital output for spectrophotometry
IPC: G01J3/42
Filed: 1973-12-03
Abstract: 1427219 Analogue to digital converter PYE Ltd 3 Dec 1973 55929/73 Heading H3H An analogue divider with digital output operates on the dual ramp principle and integrates the first voltage V s  for a predetermined time and then applies to the integrator for successive cycles determined by the time to fill a counter a voltage - V R /n<SP>x</SP> where V R  is the second voltage, n is the radix of the number system of the counter and x = p - 1 for the first cycle, decreasing by unity for each cycle; the most significant digit of the counter being set to 1 before the second and subsequent cycles, the count being stopped when the integrated voltage reaches zero and the number of cycles being counted by a second counter. The arrangment is intended for use with a spectrophotometer, the transmittance T = V S /V R  being directly derived from the values in the two counters and the absorbance = - log 10 T being derivable therefrom. Radix n may be 8 or 10 but is preferably 10 and p is preferably 3. The predetermined time may be varied to allow for differences between the beam intersites in the transmission paths of a double beam spectrophotometer. As shown, a predetermined number (10,000) is set into counter 22. At a start signal at 19, bi-stable 18 is set, FET 9 is switched on connecting V s  to the input of integrator 5 and clock pulses are gated at 20 to count down counter 22. When the count reaches zero bi-stable 18 is reset, gate 9 is closed and monostable 23 (delay t d ) is triggered. At this stage counter 28 and incremental counter 29 are at zero and decoder 30 has switched on FET 16 applying - V R /100 from resistor divider 11, 12, 13 to FET gate 10. At the end of delay t d , bi-stable 24 is set and enables AND gates 25 and 27. These open, since monostable 26 generates an enabling signal when in its stable state and clock pulses are applied to counter 28. When counter 28 (capacity 10,000) is full it generates a pulse which triggers monostable 26 (delay t d ) to shut gates 25, 27, increments incremental counter 29 by 1, and thus causes decoder 30 to select input - V R /10 and enters a 1 into the thousands position in counter 28. At the end of the next count (9000) when counter 28 is again full the process is repeated, decoder 30 now selecting input - V R  via FET 14. The conversion ends when the integrator output voltage (as determined by threshold device 17) reaches zero and bi-stable 24 is reset stopping the count. The value in counter 28 represents the absorbance with the value in counter 29 giving the position of the decimal point. The absorbance is derived by taking the log to base 10 of the complement of the content of counter 28 and preceding it (before the decimal point) by the value in counter 29. Circuits for doing this are described.

The output Q is normally low (Fig. 2, not shown); as the input at 18 rises to forward bias diodes 19, 20 and 21, the NAND 24 responds to two high inputs to make NAND 10 input 17 low. This makes Q high and NAND 11 now has two high inputs, so Q goes low. When input 18 falls and diodes 19, 20, 21 cease to conduct, NAND 24 output goes high; and when the input 18 has fallen far enough, NAND 11 changes Q to high, and the two high inputs to NAND 10 reset the bi-stable.

The elements 12 are carried by a movably mounted flexible support 10, and means are provided for displacing the support to move the contacts from an initial position into contact with the surface. As described, the support 10 is part of a bellows device and comprises a rubber base with a brass foil adhered on both sides thereof and is initially positioned, by utilizing stops 13, 14, so that the distance between contact element 12 and solenoid 7 pairs is the same. Compressed air from a source 19, via an electromagnetic valve 20, causes the elements 12 to abut the surface being tested. The valve 20 is opened by a control pulse from a control circuit 28 which circuit, after a pause to allow completion of the transient processes in the mechanical system, successively connects each pick-up 8 to an analogcode converter 24 via a respective filtering amplifier 23, the resultant signal then proceeding to a digital register 25. The valve 20 is then closed and the support returns, under the action of springs 16, to its initial position. The device may be operated when the surface to be measured is stationary or rotating.
