Abstract: 1,111,730. Endless scraper conveyer pans. RICHARD SUTCLIFFE ENGINEERING SYSTEMS Ltd., and P. D. H. COMLEY. 16 March, 1967 [22 April, 1966; 17 May, 1966], Nos. 17739/66 and 21920/66. Heading B8A. A line pan for an endless scraper conveyer comprises a floor plate 2 welded between side channels having externally V-recessed webs, brackets 3 welded across each of the recesses and an elongated aperture 4 in each bracket 3 to receive a bolt head 8 which after passing through the aperture is rotatable by a limited amount into positive engagement with the bracket 3, whereupon an attachment 12 may be bolted to the pan. The aperture 4 is conically flared 5 on its face adjacent the channel web and the bolt head is conically shaped at both ends 9 and 10 to mate with the surface 5 and the surface 11 of the V-recess. The bolt head 8 which is of the same elongated shape as the aperture 4, is passed through the latter and rotated through 90 degrees whereupon the edges of the head engage diametrically opposed abutments formed on the bracket 3 where the conical flaring is not provided. The head 8 is therefore held to facilitate tightening of a nut 13 securing the attachment 12. In a further embodiment (not shown), the abutment means is provided by the shank of the bolt having an elliptical or oval crosssection. The minor axis of the section passes through the aperture in the bracket and the major axis engages the aperture when the bolt is rotated through 90 degrees.

Patent GB-613273-A (GB)
Title: Improvements in and relating to apparatus for the production of variable frequency alternating voltages
IPC: A61N1/32
Filed: 1946-06-14
Abstract: 613,273. Photo-electric apparatus for producing alternating currents. BRITISH THOMSON-HOUSTON CO., Ltd. June 14, 1946, No. 17970. Convention date, June 18, 1945. [Class 40 (iii)] To produce alternating currents which are of variable frequency and are amplitude modulated at a variable frequency, particularly for use in electro-therapy, a pair of photo-cells is provided which are excited intermittently and alternately from a source of light and are used to reduce the grid potentials of a pair of valves normally biassed to cut-off so that each valve supplies one half of the cycle. The amount of light falling on the cells is also varied to modulate the amplitude of the output wave at an adjustable frequency. As shown in Fig. 1, a motor 10 drives a slotted disc 6 through widely variable gearing consisting of plates 13, 14 and 15 and rubber rollers 16 and 17 (shown dotted). Adjustment of the position of these rollers by a knob 31 enables the speed of the slotted disc 6 to be varied between very wide limits. The disc intercepts the light from a source 3 falling on photo-cells 1 and 2 after passing through an aperture 4. Due to the rotation of the disc the cells are illuminated one after the other. Similar adjustable gearing driven by a motor 45 reciprocates a light chopper 8 by means of the mechanism shown at R and thus enables the wave to be amplitude modulated at any desired frequency. The output of the cell 1 (Fig. 2) is used to reduce the bias of a triode valve 71, and the increase in current in this tube alters the bias on a further tube 74 which is normally biassed to cut-off. As the resistance of the cell changes in response to light falling on it, the triode 74 is rendered conductive. A full-wave rectifier 60 supplies the anode current for the output valve, and the anode current for triode 71 is supplied partly from the full-wave rectifier 60 and partly from the half-wave rectifier 61 through smoothing circuits, both being supplied from a centretapped transformer. A duplicate arrangement embodying cell 2 supplies the other half of the wave.

Title: Liquid analysis apparatus with closed flow cell
IPC: B01D19/00
Filed: 1961-05-18
Abstract: <PICT:0919759/III/1> <PICT:0919759/III/2> In the analysis of a flowing liquid in an automatic colorimeter wherein the flowing liquid is segmented by the introduction of air or an inert gas thereby to cleanse the walls and minimize sample contamination, the sosegmented stream is passed through a passageway bearing a suction pipe which removes the gas segments before the liquid passes through the colorimeter cell.  In the Figures the liquid to be analysed is introduced by pump tube 38 and the air or inert gas by pump tube 40. The two streams merge at fitting 32 after passage through conduits 34 and 36 respectively, and the segmented stream flows through conduit 42 where it joins a stream of processing liquid or colour reagent flowing in conduit 44, the processing liquid being introduced into the system by way of pump tubes 46 and 48 and conduits 50 and 52 and being mixed in helical mixing coil 56.  The treated segmented stream then passes through conduit 58 to helical mixing coil 60 where the liquids in each of the segments L are mixed with each other.  The segmented stream passes to separating device 62 (Fig. 2) where the air segments are aspirated through tube 72; the liquid passes on to blender 76 and enters the colorimeter cell 18 at 26 and leaves at 28. The analysis is based on the visible light transmittance of the sample in the cell, the degree of absorption of the light by the liquid being measured by a photo-electric device.  Pump 12 may be of any suitable type, it may comprise platen 82 and flexible pump tubes 38, 40, 46, 48 and 72 which are simultaneously compressed progressively along their lengths by the longitudinal movement of transverse pressure rollers 84.  The apparatus can be used for the continuous analysis of a series of samples or for the analysis of a continuous liquid stream, e.g. it can be used for determining the chloride content in boiler feed water.  The boiler feed water is continuously supplied to 38, air is supplied to 40, a 6% solution of ferric alum to 46 and a saturated solution of mercuric thiocyanate to 48.  The colour of the stream is measured in cell 18 and the results recorded on recorder 16.  Specifications 774,711, 817,070 and 839,649 are referred to.

Title: Improvements in terminal blocks for use in connecting up electrical measuring apparatus
IPC: G01R11/04
Filed: 1936-06-30
Abstract: 471,283. Connecting-devices for electric instruments; distribution boards. LANDIS & GYR AKT.-GES. June 30, 1936, No. 18133. Convention date, July 27, 1935. [Classes 37 and 38 (i)] In a terminal block for use in con. necting up electricity meters or the like, having a set of terminals, each terminal extending across the block and affording means of connection on both sides thereof, each set of terminals is associated with each current winding of the meter or the like and has mounted above it an insulated transverse conducting strip capable of being electrically connected to the terminals as desired bv means of non- removable set-screws, each of which is adapted to engage an associated terminal of the set and can be moved into and out of engagement with the conducting strip. The terminal block 1 is provided with pairs of pressure terminals, each pair serving to connect the mains supply to one end of a pressure winding, and a set of terminals 4 associated with each current winding of an electrical measuring apparatus, there being per phase two pressure terminals and three terminals 4, a further pair of pressure terminals being common to all phases. The pressure terminals of each pair lie behind one another and can be connected by a longitudinally movable strip. The terminals 4 extend across the block 1 and are formed with holes 6 and clamping screws 7 so that conductor wires may be inserted in both sides. Above the terminals 4 of each phase is mounted a transverse conducting strip 9, insulated from the terminals by a part 8 of the block but adapted to be connected thereto by screws 13, one of which is provided for each terminal. The screw 13 passes through an enlarged hole 11 in the strip 9 and is screwed into the under - lying terminal 4. The screw is prevented from complete withdrawal from the terminal 4 by forming a flange 14 on its end. When the screw 13 is unscrewed there is no connection between the strip 9 and the terminal 4, but upon screwing down, the underside of the head of the screw makes contact with the strip 9 and thus connects it to the terminal 4. By this means different connections of the measuring apparatus to the supply may be made.
