Title: Handling apparatus for elongated objects
IPC: B65G25/00
Filed: 1967-10-16
Abstract: 1,200,092. Conveyers. R. SENARD & FILS ETABS. 16 Oct., 1967 [14 Oct., 1966], No. 47088/67. Heading B8A. Handling apparatus for metallic bars 1 comprises a chain conveyer 2 which feeds a first series of rack-bars 4-6 and a second series of rack-bars 14-16. The ends 13 of the bars 1, which may overlap as they are fed by the conveyer 2, are engaged by movable rack-bars 4, 5. As the bar ends 13 are advanced step-by-step, the remaining parts of the bars 1 on the conveyer reach the second series of rack-bars 14-16 and, as they move up inclines 28 of movable rackbars 17, 18, the bars 1 are shaken and disentangling is facilitated. The speed of advance caused by the rack-bars 4, 5 is greater than that of the conveyer 2. The ends 13 of the bars 1 are moved away from the upper part of rack-bars 4-6 by a rotating arm 33, the bars 1 passing under a guide 29 having a counting device 30. After a predetermined number or weight of bars has been collected on a bed 32, the conveyer 2 and the rack-bars 4, 5 are stopped although drive to the rack-bars 14-16 continues. Rack-bars 4, 5 are driven by a motor 11, through a gear train 12 and eccentrics 7, 8; 9, 10. A motor 24, through gears and shafts 25-27 and eccentrics 19, 20; 21, 22 drives the rack-bars of the series 14-16. Instead of pairs of movable rack-bars, there may be rack-bars in threes with eccentrics offset by 120 degrees.

Abstract: 1398909 Photo-electric displacement measurement SOC D'OPTIQUE PRECISION ELECTRONIQUE ET MECANIQUE 13 Oct 1972 [13 Oct 1971] 47377/72 Heading G1A In a displacement measuring system in which a linearily movable measuring scale 3 is interposed between a source 1 and energy detector A, B, C, the source energy is controlled by linearly combining the signals from at least two detectors, comparing the combined signal with a reference and using any difference to alter the source output. When measuring scale 3 which comprises opaque and transparent sections is moved relative to light source 1 and detector A, B, C, pulses are fed to impedance matching circuits 41, 42, 43 and these pulse trains are combined and fed to a counter (not shown) for measuring the displacement of scale 3. The pulse trains are also fed to combining circuits 81, 82, 83 where the voltages are combined in pairs and fed via diodes 91, 92, 93 to the base of transistor T, in control circuit 7. The combined voltage is compared with a Zener generated reference in transistor T2 and the difference controls transistor T5 which controls the power supplied to source 1. The scale may be vertical i.e. interference fringes.

Title: Rc sine wave oscillator
IPC: H03K4/02
Filed: 1970-10-12
Abstract: 1329621 Frequency modulation; sine wave oscillators HASLER AG 12 Oct 1970 [14 Oct 1969] 48452/70 Headings H3R and H3T An RC sine wave oscillator with variable frequency comprises at least one electronic switch 5, 6 for periodically switching at least one frequency determining resistance between two values with a high switching frequency relative to the oscillator frequency and an adjustable keying ratio. The oscillator is repetitively switched between two frequencies by a control signal of high frequency and of an adjustable keying ratio so that a mean frequency of an adjustable value may be obtained. The control signal may be derived from an impulse generator, divider, gate circuit combination producing impulses with adjustable spacing. Alternatively, the control signal may be derived from rectangular impulses whose leading, trailing edges are dependent on the phase difference between two series of impulses or derived from the zero crossings of an A.C. signal or having a keying ratio linearly dependent on a measured variable.  In a Wien bridge type of RC oscillator wherein resistances 11, 12 are periodically switched in and out of the circuit by electronic switches, the mean frequency depends on the switching rate. The switch may be constituted by an FET or by a bipolar transistor 20 controlled by a trigger circuit 23, 24 turned on and off by pulses e.g. from an impulse generator. The values of resistances 25, 26 are adjusted so that the emitter potential remains unaffected by the switching voltages. The switch may be arranged to pass A.C. signals as well as D.C. For switching large A.C. signals, the collector emitter path of a further transistor (32, Fig. 4, not shown) is connected in series with the base emitter path of switch transistor 20.

The chopper comprised a reciprocating plate containing two windows and is operated by electromagnets with which the two output circuits of the photo-multiplier are synchronised. The sample cells have lithium fluoride windows. The mirrors are adjustably mounted and are of aluminium, coated on their non-oxidised surface with lithium or magnesium fluoride. The photo-multiplier has a protective casing of Á-metal. The use of solid specimens is mentioned.
