Title: Instrument for measuring smoke density
IPC: G01N21/29
Filed: 1933-03-23
Abstract: 414,817. Photometric apparatus. OWENS, J. S., 47, Victoria Street, London. March 23, 1933, No. 8791. [Class 97 (i).] The sky adjacent smoke issuing from a chimney top is observed through a rotating black compound disc A out of which sectors have been cut, the grey formed by the rotating disc furnishing a means of measuring the density of the smoke by comparison. The individual discs are similar and their solid sectors are of such width that the compound disc will pass no light when each disc is at an angle with the previous disc equal to the angle of the solid sectors. When the sectors of the discs are brought into coincidence the maximum transmission of light takes place. In order to effect adjustment of the light transmission while the apparatus is running the three left hand discs are frictionally coupled to a shaft S while the right-hand disc is rigidly attached to a hollow shaft H. A pinion P drives these shafts by a pin J which enters a helical slot in shaft H and a straight slot in shaft S. When the shafts are moved longitudinally by screw B they are caused to rotate relatively to each other owing to the difference in shape of their slots. A pin L attached to the right-hand disc and engaging in steps cut in the other discs, gathers up or spreads out the solid sectors of the discs in accordance with the direction in which shaft H rotates relatively to shaft S.

Title: Improved device for tensioning overall chains for vehicles
IPC: B62D55/04
Filed: 1933-03-23
Abstract: 412,361. Chain strainers. KENNEDY, D. S., Harewood Forest Works, Longparish, Hampshire. March 23, 1933, No. 8793. [Class 45.] A chain-tensioning device for overall chains passed round vehicle wheels, of the kind employing a flexible straining member c for drawing the ends of the chain a together, is characterized by the fact that the straining member is connected to the two ends of the chain, either directly or by means of the pulley or pulleys round which it is passed, at points lying on the pitch line of the chain. Thus, when the chain has been drawn tight its upper run forms a straight line and the two ends can be readily coupled together. The straining member may be tightened either by hand-operated gear or by the movement of the vehicle. In the construction shown the overall chain comprises arched shoes a and connecting chain links b, and a tensioning chain or rope c is passed round pulleys d mounted on spindles e temporarily secured to the links b one end of c being hooked to the frame of one of the pulleys. The other end of the chain c is passed through an anchoring device comprising a pair of plates k, Fig. 4, connected together by three pins k<1>, k<2>, k<3>, the chain passing over a grooved pulley or sprocket mounted on k<3>. A pawl k<5> pivoted on the pin k<2>, forms a stop for the chain. The pin k<1> engages an eye on a bracket l, of which there may be four, suitably placed on the vehicle so as to lead off the chain at a suitable angle. When the chain c has been drawn tight past the pawl k<5> movement of the vehicle will draw the ends of the overall chain or track a together for coupling. The sprocket k<4> over which the chain c passes may be fixed on a spindle having squared ends to receive an operating handle, so that the ends of the overall chain may be drawn together by rotating this handle. The spindles e of the pulleys d may have reduced ends fitting into the links b, or they may be secured to the links by screws passing through the links and screwed into the spindles. In a modification the straining member c is in two parts, one part forming a bight to which the other part is secured, the two ends of the bight being located one on each side of the track a and passing over co-axial pulleys mounted on spindles separately secured to the side links b of the track. Specifications 350,230, [Group XXV], and 367,249, [Group XXXI], are referred to.

Title: Improvements in and relating to late-news devices for printing machines
IPC: B41F13/46
Filed: 1929-03-19
Abstract: 326,361. Marks, Sir G. C., (Wood Newspaper Machinery Corporation). March 19, 1929. Late news, means for printing.-A late-news device is arranged adjacent to the drag roller and former and can print on any one of a number of webs coming from printing-couples arranged at both sides of the drag roller. The device may comprise a fudge cylinder and two impression rollers which are of circular and mutilated section respectively and are shifted axially to cause printing to occur at each revolution or alternate revolutions of the fudge cylinders as required for printing on uncollected and collected sheets, the fudge cylinder and impression rollers also being shiftable axially as a unit to permit of printing ,on different parts of the web. In the device shown in Figs. 1 and 3 a fudge cylinder 21 and impression rollers 30, 31 are mounted on shafts 18, 19 which are mounted in the framework 12 and are adjacent to and above the drag roller 10 and former 11. The fudge cylinder is arranged between collars on a frame 16 which can slide on a cross-bar 14 and rod 17, and supports inking rollers 22. The impression rollers are arranged between collars on a frame 15 which can slide on a cross-bar 13. The fudge cylinder and impression rollers are one half and one third the radius of the press-cylinders respectively, the impression roller 30 being circular, and one half of the impression roller 31 being reduced to prevent cooperation with the fudge cylinder. The shaft 18 is driven by a chain 23 from the drag roller and is geared to the shaft 19, the fudge cylinder and impression rollers making two and three revolutions respectively for each revolution of the press cylinders. The frame 15 is shifted to register the impression roller 30 or 31 with the fudge cylinder and thereby determine whether the fudge cylinder shall print during each revolution or alternate revolutions as required for uncollected or collected sheets respectively. The frames 15, 16 are shifted across the press to permit of printing on different parts of the web.

Patent GB-640976-A (GB)
Title: Improvements in the manufacture of thiourea
Filed: 1948-04-01
Abstract: Thiourea is prepared by progressively introducing free cyanamide, i.e. in the crystalline or fused state, into an aqueous solution of alkali sulphide which is maintained saturated with hydrogen sulphide. The excess hydrogen sulphide prevents side reactions by converting any base formed into the corresponding sulphide and is maintained by passing a current of the gas through the reaction vessel during operation.  Temperatures instanced are 30-60 DEG  C., particularly 50 DEG  C.  Thiourea may be isolated by crystallization from the reaction medium and the mother liquor returned for further processing.  In examples: (1) molten cyanamide at 45 DEG  C., and (2) crystallized cyanamide is fed into a closed vessel containing aqueous ammonia maintained saturated with hydrogen sulphide at 45-50 DEG  C. and when reaction is complete the mixture is cooled to 15 DEG  C., crystals of thiourea collected and mother liquor continuously recycled, in (3) sodium sulphide is prepared and used in place of the ammonium sulphide of (1), and in (4) a continuous process is described in which molten cyanamide is run into aqueous ammonium sulphide saturated at 20 DEG  C. with thiourea and after reaction at 45 DEG  C. the mixture is passed to a cooling vessel at 20 DEG  C., the precipitated thiourea filtered off and the mother liquor recycled.  Specifications 634,463 and 636,600 are referred to.

A furnace wall comprises stacks of identical tiles, each stack independently supported by a member engaging only the lowermost tile of the stack, and having a downwardly extending part engaging the top tile of the stack immediately below to prevent its outward displacement. Vertical stacks of identical interlocking tiles 20 are supported by hangers 24 slidably mounted on horizontal bars 30. One end of each bar 30 is bolted to a vertical H-section support 18, and the other end is secured to an adjacent H-section support 18 by a bolt passing through a slot in the bar 30 so as to allow for expansion. Each hanger 24 has a horizontal flange 28 supporting the lowest tiles 20 of two adjacent stacks, and a vertical T-section part with arms 26 engaging grooves 23 in the tiles. The outer part of the tiles is reduced in size, and a groove 21 on the top of each tile engages a rib 22 on the bottom of the tile above. The vertical spacing of the horizontal members 30 is such that there is a gap between the uppermost tile of one stack and the lowest tile of the next stack of less depth than the interlocking groove 22 in the top tile so that the tiles interlock while allowing for expansion. A downward extension of the arms 26 engage the tiles of the stack below that which the hanger 28 supports.
