Abstract: 702,462. Supply systems for space discharge apparatus. PHILIPS ELECTRICAL INDUSTRIES, Ltd. Nov. 28, 1951 [Nov. 28, 1950], No. 29079/50. Class 38 (4) To save heavy cabling and to prevent instantaneous peak loads on the supply system, the high tension supply to an X-ray tube 25, which tube takes a heavy current for a short period of time, is obtained from a generator 3 driven by a relatively small motor 1 capable of driving the generator up to its operating speed but not maintaining it thereat when under continuous load, so that the kinetic energy of the motor-generator system provides at least part of the load. As shown, the generator 3 comprises an H.F. alternator the field 6 of which is controlled by a stabilizer 4 to provide substantially constant output voltage to a variable voltage auto-transformer 7 which feeds, through an isolating switch 10, 10<SP>1</SP> and an H.T. transformer 14, a bridge-connected rectifier 18 ... 21 of which the output is connected across the X-ray tube 25. Following closure of an isolating switch 2, 2<SP>1</SP>, and when the alternator has attained its operating speed and the transformer is correctly adjusted, as may be indicated by a voltmeter 9,- a frequency meter or a tachometer, an exposure may be effected by closure of a switch 13 which causes a time switch, which may be as disclosed in Specification 568,185, to close by means of a solenoid 12 the isolating switch 10, 10' for a predetermined exposure period. The Figure shows a circuit for automatically initiating an exposure on attainment of correct alternator speed, and which comprises the frequency responsive series resonant circuit for a capacitor 27, an inductor 28 and a variable resistor 29 in series with a rectifier bridge 30 across the alternator output. The rectifier 30 feeds the input winding 31 of a magnetic amplifier 32 where output windings 33, 34 control the supply 37 to a time switch control solenoid 36 to close switch 13 when the series circuit resonates at full alternator speed. The motor 1, which may be D.C., or a squirrelcage or capacitor type A.C., may be disconnected as the load is switched on. A constant voltage transformer 26 may feed the X-ray tube filament. Specifications 13854/08, [Class 38], 16853/13, [Class 39 (i)], and 111,570, [Class 38 (iv)], are referred to.

Title: Control of the movement of goods in an automatic processing plant
IPC: C25D21/12
Filed: 1971-06-23
Abstract: 1350405 Vehicle control SCHERING AG 23 June 1971 [23 June 1970] 29426/71 Heading B7N In an arrangement for controlling the movement of articles on transport carriages to or from processing stations in, e.g. an electroplating plant, a central control unit is provided which is coupled to the carriages to control the picking up and putting down of articles at the stations and includes information storage circuits responsive to the state of occupation of the stations. The carriage TW1 runs on track T above plating baths B1-B5 each of which has an associated switch member ST1-ST5 which is actuated by the cam means N1-N3 on the vehicle as it moves above the bath. The carriage is formed with a hook member H1 which is raised or lowered to remove an article Y from a plating bath or to insert an article X in a bath. Assume an article has to be inserted in a particular bath a signal is applied to "putting in" line 1 and switch M is set to the required bath. At this time stage SR2 of stepping register SR is in the "1" state and supplies a full speed signal on line 3 to the carriage carrying the article. When the first carriage cam N1 actuates switch ST at the required station the register is stepped to move the "1" to stage SR3 which via OR gate G11 supplies a slow speed signal to the carriage and when cam N2 actuates the switch the "1" is switched to stage SR4 which supplies a stop signal on line 4. This latter signal with the "putting in" signal provides an output from AND gate G14 which via OR gate G17 and line 6 actuates the lower mechanism of the hook H1. When the hook is fully lowered a signal on down line 8 is applied via AND gate G19 and OR gate G10 and switches the first stage SR1 of the register to "1" and clears stage SR4. The carriage is now controlled to slow speed via OR gate G11 so that the hook moves out of the article being deposited and a raise signal is applied to the hook mechanism via AND gate G12 and OR gate G16. When the third cam engages the switch the "1" is stepped to stage SR2 which supplies a full speed signal to the carriage. During pick up of an article the hook is lowered during the first slow speed phase to engage the article and is raised when the carriage is stationary. An information storage circuit, Fig. 2 (not shown), is provided for each bath and this is set to indicate bath occupied when the associated switches ST is closed, the hook has been lowered and has reached the bottom of its travel. The store is cleared when the switch ST is again closed, the hook has been raised and reached the top of its travel.

Abstract: 390,235. Field control of D.C. motors. FORGES ET ATELIERS DE CONSTRUCTIONS ELECTRIQUES DE JEUMONT, 75, Boulevard Haussmann, Paris. Oct. 27, 1931, No. 29747. Convention date, Dec. 6, 1930. Addition to 386,009. Drawings to Specification. [Class 38 (iii).] In a system described in the parent-Specification, commutation of a current equal to twice normal current at half magnetic flux, is avoided by automatically limiting the armature current. This is effected in one arrangement by energizing the independent field winding of the exciter from the supply or other source, such as an auxiliary generator or a battery, in series with the exciter armature. In the case of two or more traction motors, the exciters are connected in series, or are connected to tappings on a potentiometer. The independent 'field may also be in series with a pilot exciter driven at a speed proportional to that of the vehicle, and having a shunt field and a field supplied from the line. For preventing shocks when changing over from coasting to driving or regenerative braking, the independent field of the exciter may be connected across the contacts of a main line switch through a double pole switch. Any difference between the voltages of the supply and motor is corrected by the current produced in the independent field winding of the exciter.
