Title: Improvements in Electromagnetic Clutch Control.
IPC: F16D48/06
Filed: 1967-11-16
Abstract: 1,187,079. Clutch control. GENERAL ELECTRIC CO. 16 Nov., 1967 [11 Jan., 1967], No. 52110/67. Heading F2L. [Also in Division G3] In a circuit for controlling the slip of an electromagnetic clutch 11, Fig. 1, to maintain the speed of the output shaft 14 constant, energization of the clutch coil 17 is controlled by an SCR 18, the gate 21 of which is in turn controlled by current from coil 17 passing through a dropping resistance 32, which current may be diverted through a transistor 28 when rendered conductive by a base potential derived from a tacho-generator 16 driven by the shaft 14. An increase or decrease in the conductivity of transistor 28 caused by changes in speed of shaft 14 causes SCR 18 to turn on later or earlier respectively in each positive half-cycle of the supply current to decrease or increase the energization of coil 17. The regulated speed of shaft 14 may be adjusted by a variable resistor 34 which varies the base potential of transistor 28. The circuit provides control of the SCR up to the peak of each halfcycle of the supply. Fig. 2 shows a modification wherein control over each full half-cycle is provided by a capacitor 41 connected in parallel with the transistor 28 and charged through a Zener diode 38 to a potential sufficient to turn on the SCR 18. The charging time of capacitor 41 depends on the collector-emitter resistance of transistor 28 which is dependent, as before, on the base potential and hence the speed of shaft 14. In a further modification, Fig. 3 (not shown), the capacitor is connected in parallel with the dropping resistor 37 of Fig. 2 and is sized so as to become charged early in each half-cycle of the supply depending on the conductivity of transistor 28 which forms a current divider with the capacitor. In this embodiment the SCR conducts early in each pulse or not at all so that large pulses may be produced for changing the speed of large inertial loads.

Abstract: 1,209,637. Optical magnetometer. SINCLAIR RESEARCH Inc. Nov. 17, 1967 [Nov. 17, 1966 (2)], No.52352/67. Heading G1A.

F. magnetic field of a frequency diminishing the alignment of atoms into the body and including a variable frequency oscillator the frequency of which is swept about a pumping frequency determined by the output of a radiation detector; means are provided for counting the frequency of the oscillator over an integral number of sweep cycles. In an optical magnetometer light from a source 20 Fig. 2 impinging on a detector 26 via a radiation absorption cell 22 is applied also to a detector 25 for reference purposes, the paths including collimating lenses 40, 48, polarizers 42 42<SP>1</SP> and a filter 44 which, if the gas in the cell is helium, may pass only 1À08 micron light. The cell outputs which may be resistive or voltaic are compared in for example a Wheatstone bridge and serve to control a variable oscillator 66 producing the depumping frequency for the cell. Alkalivapour, rubidium and cesium instruments as well as metastable helium are referred to. The arrangement is described in connection with geological surveying in an aeroplane bird. The frequency meter 138 Fig.3 includes a master oscillator and frequency dividers whereby a waveform is generated to sweep the depumping oscillator about its mean frequency and counting periods of the frequency meter are controlled by the same divider output so that the counting is always effected over a number of complete cycles. The absorption cell 112 may be excited by a discharge between electrodes in the cell, an R.F field, by a piece of radioactive material, or by X-rays, and the output of detector 120 is applied to adjust the depumping oscillator for maximum absorption through a phase controlled rectifier 134 fed also from the divider output, a pulse delay circuit 140 ensuring phase correspondence of wanted signals so that the rectifier serves also as a filter.

Abstract: 1,154,122. Endless conveyers; sorting letters FMC CORP. 25 Nov., 1966 [17 Jan., 1966] No. 52765/66. Heading B8A. [Also in Division G4] Letter sorting apparatus comprises an easel conveyer TE which has a movable surface on which letters L can be displayed in a position in which they are inclined to the vertical, the letters L being fed individually from a tray by a singulator Si on to the band 10 of the conveyer TE where they are engaged by lugs 12 (see L8 at station (a)), the conveyer TE being actuated intermittently by a read and code operator through a pedal P. The letter is carried past a spray control photo-cell PC-1 (L7 at (b)) and is sprayed with a strip of magnetic material m by a spray unit Sp. The letter continues to a read and code station (c) (L6) where the operator transfers address information w from the letter to a keyboard K and after selecting a key X, Y or Z (e.g. out of town; local or air mail) the operator presses the pedal P closing switch S. When a lobe on a continuously driven " start " synchronizing cam 26 on a main drive shaft 20 closes a start switch S1 a clutch Cl is magnetically engaged causing shafts 18, 16 to advance the easel band 10 by one increment. Letter L6 is thus transferred to a continuously running vacuum conveyer belt 30 which is shown advancing a letter L5 across a write station (d) where a write head W imparts the coded information w and x, y or z on the strip m. A letter L4 is shown crossing a read station (e) where the code x, y or z is sensed by a magnetic read head R. A letter L3 is shown (in phantom line) at station (f ) as the letter is about to be picked up by a lug 42 on a band 40 of a transport conveyer TC. It is at this station (f) that the synchronizing action of the cam 26 and the start switch S1 are important so as to ensure that a letter at station (f ) is advanced on to the band 40 in a zone between a pair of lugs 42 and preferably adjacent the trailing lug of the pair. On the transport conveyer TC a letter L2 is shown at a station (g) one lug pitch or increment downstream of station (f) and a letter L1 is shown at station X opposite a remotely controlled discharge device DX, part of a stacker St. The coded information from the read station (e) is fed to a shift register BR which is fed with a shift signal by a shift cam 70 on the main drive shaft 20 closing a shift switch S3 in synchronism with the advance of the lugs 42 on the transport conveyer TC. On successive shift pulses the information is shifted from register section "e " to "f ", " g ", "x", " y " and " z ". Comparators x<SP>1</SP>, y<SP>1</SP> and z<SP>1</SP> are connected to sense the coded information x, y and z and when a match occurs the associated discharge device receives a discharge signal from the relevant comparator. As shown L6 is assumed to be information code x and is discharged at station X.

The print head is moved to the left at the same speed as the web while pressing the tape and web against the back-up means so as to print on the web. The tape is advanced while the print head moves to the right out of contact with the web, while during the printing stroke a tape support 96 carried by the print head is moved to the left. The vertical movement of the print head is controlled by a cam 22 acting on a slide block 46 and by springs 50, while the horizontal movement is controlled by a rod 28 mounted on the cam and engaging in a slot 84 in a lever 82 pivoted on a fixed rod 58 and secured at its lower end to the print head so as to slide the latter horizontally in a groove 66 in a block 64 caused by the block 46.

The apparatus is coupled to packaging means which feeds the web and drives the printing head through a shaft 104 and gears 102, 20. The back-up means may be an endless belt 90 moved by the web when pressed against it, or may be a pad slidable by contact with the web in a fixed guide and returned by a spring when the print head releases the web.
