IPC: G01N23/10
Filed: 1966-10-10
Abstract: 1,158,338. Monitoring sedimentation by radiation. EUROPEAN ATOMIC ENERGY COMMUNITY (EURATOM). Oct.10, 1966 [Oct.12, 1965], No.45134/66. Heading G1A. Apparatus for analyzing the sizes of particles dispersed in a fluid, comprising a tank in which the dispersion is contained and the particles subjected to an accelerating force a source of radiation and a radiation detector arranged to receive rays from the source passing through the tank, and means for moving the tank relative to the source and detector parallel to the accelerating force, the rate of relative movement being corelated according to a predetermined programme with the differential distribution of the particles caused by the accelerating force. The diameter of particles whose concentration is measured may be varied linearly or logarithmically with time. The equation of motion of the tank is derived for instances in which sedimentation takes place by gravity or by a centrifuge. The motion may be given to the tank by a rotary or linear cam either directly or via an electric servo, Fig. 5 (not shown). X-rays from a source, Fig.3  pass through apertures in a lead shield 9, filters 19, 20 the sedimentation tube 2 and fall on scintillation detectors 3, 12. The scintillation signals are applied to a recorder 15 which plots the concentration directly. In a modification, Fig.4 (not shown) the difference in scintillation signals moves a wedge in front of detector 12 to balance the signals and the wedge position is recorded. In another modification, Fig. 6 (not shown) one detector is used, the beams being directed on to it alternately. The wedge position may be recorded directly for a gravity sedimented sample or after multiplication by a suitable function for a centrifuged sample.

Abstract: 1, 009, 049. Photo-resistor circuits. PROTECTOR G.m.b.H. Dec.18, 1961 [Jan. 3,1961], No. 45280/61. Heading G1A. A circuit contains two photo-resistive elements connected in series across a voltage source with different spectral sensitivities so that the circuit is capable of distinguishing, for example, between sunlight and radiation from a fire, that circuit also containing a radiation-producing device connected in parallel with one of said elements so as to be energized by a relative change in the resistances of said elements, and a photo-responsive device positioned to receive radiation from said radiation-producing device and arranged in a circuit to be controlled. The form shown comprises a cell R2 responsive to infra-red radiation in series with a cell B2 responsive to visible light. A neon tube G2 is connected across the cell B2 and any light from it is detected by a photo-resistive element L2 connected to an external circuit. The resistances of the cells R2, B2 will fall when radiation is incident on them. If there is a preponderance of infra-red radiation the resistance of R2 will fall more than that of B2 and the voltage applied to the tube G2 will rise sufficiently to cause a discharge in it. The initiation of this discharge can be controlled by a calibrating resistor C2. The intensity of the discharge may provide an indication of the intensity of the incident radiation. In a further embodiment the photo-resistor L2 is connected across a voltage source in series with a further neon tube, any discharge in which is detected by a further photo-resistor.

Patent GB-462398-A (GB)
Abstract: 462,398. Autographic recorders. TURNER, E. H. Sept. 28,1935, No. 26889. [Class 106 (i)] In an autographic recorder having two record strips mounted in a turntable so that one is displayed to the customer while the other is in position to be written on by the operator, the turntable is rigidly mounted on a shaft that receives a predetermined rotational movement at each opening of a cash drawer or rotation of an operating crank, means being provided to lock the shaft until the next operation, whereupon the rotational movement is continued. The autographic recorder shown in Fig. 3, is operated by the opening of a cash drawer 16. It is provided with two record strips each passing from a supply roll 38 over a platen 39 to a storage roll 40. The strips and platens are carried by a frame 37 secured to a vertical shaft 26 that is rotated through 180‹ at each operation to present each platen alternately beneath a writing aperture 15, and a reading window 14. For this purpose a gear 25 on the shaft meshes with a second gear 24 that is rigid with a star-wheel 23 rotated by a trip-lever 20 on the drawer as the latter opens. The frame is locked in its two positions by a detent 31 engaging a notched disc 27 on the shaft, the detent being disabled upon the first opening movement of the drawer by the abutment of the trip-lever 20 with a lever 30 linked to the detent. A drum sector 60 is formed to receive an advertisement or announcement and is raised into visible position relative to an aperture 13 upon the opening of the drawer. For this purpose, the sector is linked to a lever 54, 56 urged clockwise by a spring 59 to raise the sector. However, the sector is held in lowered position, while the drawer is closed, by an arm 52 that contacts the inner end of the drawer and is linked to the lever 54, 56. The strips are line-spaced by pawl- and-ratchet mechanisms, the pawls being carried by levers 45 the upper ends of which wipe past a fixed stop as the frame rotates. An alternative line-spacing mechanism comprises a worm 85, Fig. 9, engaging wheels 86 on the spindles of the storage rolls, the worm being mounted on the frame and driven by meshing with a stationary gear 81. In a modification, Fig. 7, the device is operated by a handle 66 connected by bevel gearing to the strip-carrying frame 37. In this embodiment, the locking detent for the frame is manually releasable and the drawer 16 is locked by a latch 73 normally entering a recess in the drawer but raised to inoperative position by an eccentric 72 upon the rotation of the handle.

The arm is mounted on a support 40 which is fed with liquid via a pump 34; a pipe 50 leads from the support to feed a second spray arm 48. The chambers 156, 158 are separated by partitions 180, 182 having apertures 184, 186 respectively, a second pair of chambers 172, -174 separated by partitions 188, 190 and having apertures 192, 194 being provided in the arm. The apertures are controlled by closure members 206, 208 mounted on a lever 202 which is pivoted in the arm so that, during operation, with the valve in the position shown in Fig. 6, liquid flows through apertures 186, 192 into chambers 158, 172 to rotate the arm in one direction. During this rotation the lever 202 is loaded by a torsion spring so that, when the pressure of liquid drops at the end of one washing cycle, the lever rotates under the action of the spring to ,cause the valves to close apertures 186, 192 and open the apertures 184, 194. When the next washing cycle commences the liquid flows into chambers 156, 174 to rotate the arm in the opposite direction. Reference has been directed by the Comptroller to Specification 993,692.
