Abstract: 1,090,784. Photo-electric absorption measurement. G. BUSSOTTI and G. L. DEMANGE. Nov.5, 1964 [Nov.8, 1963], No.45141/64. Heading G1A. In an absorption investigation a sample beam and reference beam are alternately received by a detector and the signals corresponding to the sample beam are directed to a recording and indicating device and those of the reference beam to a galvonometer: pairs of readings can be compared to provide a differential absorption value for the sample relative to a reference sample in the reference beam or the scale of the recording or indicating device be calibrated to read the differential absorption directly and the corresponding intensity of the two beams prior to transmission through the samples maintained constant by a feedback signal from the galvonometer. In Fig. 1 radiation from a source 1 passes via a monochromator 4 and is split into two beams for transmission through a sample cell 9 and reference cell 10 which beams pass alternately to a detector 19 by a shutter 15 having a pair of concentric slits 17, 18. The detector outputs are switched to a recorder or indicator 25 for the sample beam and a mirror galvonometer for the reference beam by means of a switch 20 controlled by light from source 21 to detector 23 which conducts as light passes through slit 17 in synchronism with the reception of the sample beam at detector 19. The detector 23 is sensitive only to wavelengths passed by filter 22 which are different from the wavelengths to which detector 19 is sensitive. The mirror galvonometer reflects a beam on to a differential detector 27 which controls a diaphragm 31 to maintain constant the intensity of light entering the monochromator, or alternatively the detector 27 output drives a potentiometer (not shown) in the output circuit of detector 19.

Title: Improvements in coin testing mechanisms
Filed: 1962-12-10
Abstract: 961,264. Coin testing mechanisms. K. C. BATEMAN. Dec. 10, 1962 [Dec. 8, 1961], No. 46563/63. Heading G4V. A mechanism for testing coins has two opposed cams 27, 28, Fig. 6, with ledges 33, 34 against which the rimmed edge of a coin strikes, and with shoulders 35, 36 which gauge the annular thickness of coin as the cams rotate under the weight of the coin. The cams are pivoted eccentrically on the end 5 of mounting rods which may be rotated to vary the spacing between the cam edges. As seen in Figs. 1 and 3 the mechanism delivers a coin to the cams by means of a runway 14 beneath the hopper 10, 11. Should a coin jam in the cams it may be cleared by a pin 62 which sweeps underneath the coin at the same time as a wheel 73 descends and engages a flange 75 to open the clearance plate 4. If a coin negotiates the cams successfully it falls to a runway 46, Fig. 3, and travels on to an adjustable runway 47 which pivots at 49, Fig. 1, and by means of the setting screw 50 leaves a gap between the edge of the runway and the back plate so as to eject thin coins therethrough. While passing along runway 46 acceptable coins are supported at their upper extremity by a bearing edge. Coins of too small a diameter are tipped on to a bent back flap 51, Fig. 3, which arrests them. A pressure arm 53 encourages coins to tilt against the flap. An arrested coin is released by easing the clearance plate 4 open when the coin falls to be collected by reject shoots 77. From the runway 47 coins fall on to an anvil 58 from which they bounce over a hoop 59 to a collecting shoot if they are of the correct elasticity. In falling on to the anvil the coins pass a permanent magnet 61 which deflects ferrous discs so that their rebound from the anvil results in rejection. When falling on to the runway 46 after passing through the cams 27, 28,a coin deflects a pin 53, Fig. 1, arranged to capture washers by entering into the hole in a washer as it sets off down the runway.

A device for braking and restarting the shaft 3, Fig. 1 (not shown), of revolution of a cloth roll 1 positioned adjacent a treating machine so that the cloth does not continue to unwind when the machine is stopped or, suddenly pull when the slack is taken up as the machine is restarted, comprises an energy accumulator A which is brought into connection with the shaft 3 when the machine is stopped and which temporarily drives the shaft 3 when the machine is restarted. The end 10 of the shaft 3, which is rotatably supported in bearings 4, 5 of supporting brackets 6, 7, Fig. 1 (not shown), on a transport truck (not shown), is coupled, by means of keying 12, to a sleeve 11 which is rotatable in a bearing 13 in a frame 14 of the device A and which is connected a shaft 16, the opposite end of which is supported in a bearing 17 in the frame 14. A drum 18, which houses a strip-like spiral spring 22, and which is rotatable by means of bearings 19 on the shaft 16, comprises, two independently-rotatable parts one of which consists of an outer wall 18 connected to the outer end of the spring 22 and a side wall 34 which carries lateral ratchet teeth 21 and is connected to a ratchet wheel 33. The other drum part comprises an inner wall which is connected to the inner end of the spring 22 and a side wall 20 which has peripheral ratchet teeth 29 and which carries one half 28 of a clutch the other half 26 of which is axiallyslidably and non-rotatably-mounted on the shaft 16 and is mounted within a bearing 38 of an operating lever 37. The ratchet teeth 29 engage a pawl 39 which is pivoted to the frame A at 39 and is loaded by a spring 30, the ratchet teeth 33 being engaged by a pawl 32 carried by a lever 31 fast on the shaft 16. If the treating machine is stopped a shaft 36 which carries the operating lever 37 and which is axially-but non-rotatively movably mounted in the frame A is shifted to the left (P 1 ) by means of an electromagnet (not shown), so that a cam 35 on the shaft 36 engages the ratchet 29 and the part 18, 34 of the drum is held stationary. At the same time, the clutch part 26 is moved into engagement with the clutch part 28 so that the drum part 20 is rotated and the spring 22 is wound up, the cloth roll being gradually brought to a standstill. When the machine is restarted the electromagnet shifts the shaft 36 to the right so that the clutch 26, 28 is freed and the cam 35 releases the teeth 21 so that the outer end of the spring can ease and expend its accumulated energy through the drum 18 and the lever 31, to the shafts 16, 10.
