Patent GB-1228064-A (GB)
IPC: G01N23/22
Filed: 1969-03-28
Abstract: 1,228,064. X-ray analysis apparatus. SIEMENS A.G. March 28, 1969. [April 1, 1968], No. 16562/69. Heading G1A. [Also in Divisions B1, B8]. A specimen changer for use in X-ray spectral analysis of a sequence of samples, comprises a turn-table K provided with spindles R 1  -R 4  at the ends of which are mounted specimen cup assemblies PB 1  -PB 3 , which carry specimens to be analysed, and PB, which is intermediate cups PB 1  and PB 3  and carries a reference specimen. The apparatus rotates in steps. If the turn-table has been rotated, for example into the position shown in Fig. 1, it then stops and a lifting cylinder H lifts main T upwards, carrying with it the assemblies PB and PB 1  -PB 3 . This brings one PB 2 , of the cups into contact with the underside of charging device B and a specimen is taken through the charging aperture into the specimen cup HV2. Also, another cup PB 1  is raised into engagement with the underside of the analysis apparatus S, where a vacuum-tight contact is ensured by sealing ring OR. An X-ray fluorescence analysis is carried out on the sample using a multi-channel X-ray spectrometer comprising an X-ray tube and, for example, throughflow counter tube detectors in a radial array. Meanwhile, at the third test specimen cup assembly PB 3 , a specimen is being discharged. This occurs by, during rotation of the turn-table, a bevel gear S 3  intergral with spindle R 3  being rotated by engagement with gear segment KS, causing the spindle to rotate about its own axis and invert the cup assembly. An aperture O is provided in main plate T, so that the cup assembly can tip freely. The specimen falls to a specimen collecting device BH which can move into one of two positions, one causing a faulty specimen to be discharged via chute 6 and the other causing it to be caught in funnel PA. In other positions away from the discharge area, the cup assemblies are held upright by leaf-spring arrangements.

Abstract: 1288464 Replenishing developer baths; automatic concentration control C S OST 4 Aug 1970 [11 Aug 1969] 37616/70 Headings G2A and G3R A test strip of film is exposed, and successive samples of developer from a developing bath are applied to successive portions of the film, which are then developed; the optical density of these developed portions is sensed, and further developer liquid from a replenisher supply is added to the bath in accordance with the sensed density. The test strip 10 is wound across from a supply reel (11), Fig. 1 (not shown) to a take-up reel (31), passing through an exposure station 13 and a development and monitoring block 23. The exposure station is shown in more detail in Fig.3, the film 10 being held by a pressure pad 14 against the upper end of a block having a cylindrical bore in which is disposed a lamp 16 and masking slits 17, 18. The block 23 has two cylindrical bores 71, 81, and the film 10 passes across the open upper ends of these bores, being held against them by a pressure pad 24. Bore 71 is divided by a spacer 70 into an upper compartment 74 and a lower compartment. A sample of developer from the main bath 92 is pumped into bore 71 via an inlet tube 33, where it passes upwards through gaps 72 in spacer 70 and so floods on to the film 10, leaving the bore again through an outlet tube 34. The monitoring bore 81 has a lamp 83, light from which passes through a filter 85, to render it non- actinic, and the film 10, to a densitometer head 84. The resistance of head 84 varies according to the intensity of light incident upon it, and this resistance forms one arm of a bridge circuit Fig. 9 (not shown). Fig. 8 shows the main developing bath 92, in which photographic film 90 is being processed. Liquid is pumped through a pipe 94 leading from the bottom of the tank past junctions with tubes 33, 34, through which the samples are taken to and returned from bore 71, and back to the bath. Before discharging into the bath, the pipe 94 is constricted into a Venturi 95, to which is connected a tube 96 leading to a replenisher supply 97. Between its ends tube 96 is enlarged into a flow chamber 99 in which are located a manually operated control valve 101 and a valve 103 controlled by a solenoid 104. If the test strip is insufficiently dense, the additional light transmitted reduces the photo-resistance of the head 84, which unbalances the bridge circuit. This causes the solenoid 104 to become energized, so opening the valve 103 and allowing replenishing liquid to be added to the bath 92. The circuit arrangement Fig. 9 (not shown) is such that the amount of added replenisher is proportional to the rate of decrease in the sensed optical density.

Abstract: 1290073 Corrugating; making bellows P McCABE 11 May 1971 [11 May 1970] 22675/70 Headings B3A and B3E  Metal bellows are formed by supporting a tube W on roller assemblies 73, moving external rolls 21 into engagement with the outer periphery of the tube so as to co-operate with an internal roll 59, rotating the rolls 21 and 59 in opposite direction, and moving the rollers 21 and roller assemblies 73 together so as to deform the tube to form an annular corrugation. After the rolls 21 have been moved into contact with the tube by rams 55, the roller assemblies 73 are raised by the hydraulic raising of a subframe 61 so as to bring the tube into contact with the roll 59. The rolls 21 are then moved towards each other by actuating a ram 41 connected to a linkage 31 so as to form an annular corrugation. In another embodiment, Fig. 6, pressure rolls 103 act on the periphery of the tube and cooperate with an inner roll-105 so that when pressure is applied to rolls 103 it is transmitted to roll 105 and cause the roller assemblies 73 to be raised.

Abstract: 1296030 Valves HOERBIGER VENTIL. WERKE AG 21 Dec 1970 [19 Dec 1969] 60459/70 Addition to 1072220 Heading F2V A control valve designed for use with appliances which are fluid-impulse-operated, comprises an inlet 2, an outlet 3, a drain 26 and two operatively interconnected valve members 6, 17. The connection between the inlet duct 2 and a chamber 5, which chamber contains valve member 6, is afforded by a passage 4 and a parallel and controllably throttled passage 29, 28. The valve members are biased to the position shown. In operation, fluid at the inlet 2 passes unimpeded to the outlet 3 for as long as there is demand at the outlet. Upon such demand ceasing, the back pressure in outlet 3 causes relief valve member 17 to open and hence supply valve member 6 to close. Accordingly, the outlet passage is connected to the drain 26. The valves remain in this changed-over state until the inlet pressure is reduced. Thereafter, the pressure in chamber 5 is gradually vented via the throttled passage-the other passage 4 being closed by valve member 6-until the spring forces acting on the two valve members are sufficient to return these to the position shown-the delayed opening of valve 6 after the outlet pressure is relieved prevents a new rise in pressure within outlet 3 and hence the possibility of an unintentional actuation of the appliance connected to the outlet 3. In a modification, not shown, passage 4 may contain a check valve opening in the direction of chamber 5.
