Title: Improvements in or relating to the recovery of bromine from bromine-containing materials
IPC: C01B7/09
Filed: 1962-02-21
Abstract: A continuous process for the recovery of bromine present in the form of hydrobromic acid in a gaseous mixture resulting from the bromination of organic compounds comprises introducing chlorine gas into said mixture at 0 DEG  to 50 DEG  C., cooling the reacted mixture to -15 DEG  to 0 DEG  C. to condense the bromine formed, and recovering the bromine in liquid or gaseous form.  Both steps may be effected in a single cooled condenser, or the reaction step may be effected in one or more condensers, or the cooling step may be effected in one or more condensers connected in series or parallel, preferably maintained at - 25 DEG  C.  Where two condensers are connected in parallel, one may be operating while the other is defrosting.  The chlorine is advantageously introduced into the lower portion of the reactor.  Prior to reaction the gas mixture may be passed over silica to remove traces of hydrofluoric acid resulting from the bromination of fluorine-containing compounds. The bromine obtained may be recycled for further bromination.

Title: Improvements in or relating to recording apparatus
IPC: G01R13/30
Filed: 1928-03-05
Abstract: 314,914. Whidbourne, H. March 5, 1928. Photographic recorders; graduations of record-surface. -To record accurately time intervals a shutter or reflector carried on the axis of a balance wheel of a watch or clock is arranged to interrupt or control periodically the passage of a beam of light on a relatively movable light sensitive record-surface. The beam of light may be displaced in one or more directions on the record surface by means of a reflector operated by the moving member of a measuring instrument or other variables the magnitude of which it is desired to record. As shown in Fig. 1, the balance wheel 2 of a spring-driven watch mechanism carries a shutter 1 adapted to intarrupt the passage of light rays from a tube 3 through a mirror or prism reflector 7 to a photographic film strip 5 carried on a rotatable drum or spools 6 driven by any suitable means. A condensing means 8 and a stop 9 may be plaoed in the path of the light rays. Instead of a shutter the balance wheel may carry a mirror 10, Fig. 2, to reflect the incident light thereon from a lamp to the film strip. In the form shown in Fig. 3, as applied to the recording of two variable quantities the light from a source 11 falls periodically through the oscillations of the balance wheel and shutter on a mirror 13 and is reflected on to a fixed photographic strip 5, concentric with the condensing lens 8. The mirror 13 is carried by a rack 15 of circular cross-section and moves the beam of light transversely by the action of a sector 14 in accordance with variations in one quantity. The beam may be moved angularly according to the other variable by means of a crank arm 16 having a sliding connection 17 with a driving pulley. A pendulum maintained by any suitable means may be substituted for the balance wheel.

A number of switches 10 arranged in a row on a plate 12 and so as to be operable in a given sequence, have guards 14 ... 14c normally obstructing the operating levers 11 ... 11c, the guard 14 of the first switch being withdrawable to allow operation of that switch and, in moving, freeing the guard of the second switch, the withdrawal of the guard of the second switch freeing it (for operation) and at the same time freeing the guard of the third switch, and so on. The guards are secured to respective guided, non-rotatable spring plungers 13 ... 13c, of which 13 has a sloping-back slot 23 and a cam 29, and the remainder straight-sided slots 24, 26, 28, respectively, and cams 30, 31, 32. Plungers 13a, 13b have sloping-back slots 25, 27. Locking levers 20, 21, 22 pivoted at 19 are spring-biased to co-operate with the slots, the normal positions being as shown in Fig. 2. When guard 14 is pulled out to free switch lever 11 for movement to the Fig. 3 position, slot 23 engages lever 20 to lift it out of slot 24 to free guard 14a. When the latter is pulled out, slot 25 lifts lever 21 to free guard 14b and when 14b is pulled out, slot 27 raises lever 22 to free guard 14c. Each lever as the guard is pulled out rides over the appropriate cam 29 &c. and falls behind it to retain the guard in withdrawn position, the last guard being retained by its cam 32 obstructing a lever 36 having limited pivoting movement on lever 22. The guards can all be reset together by rotating the levers about pivot 19 by means of a cam 44 on a hand-actuated spring-returned shaft 40.

Title: Improvements in or relating to the manufacture of pipes, tubes and the like, and apparatus for use therein
IPC: B28B21/42
Filed: 1922-03-09
Abstract: 199,084. BillÚ, L. March 9, 1922. Moulding pipes and tubes; strickles.-A pipe is made with an inner layer or layers 2, Fig. 2, of asphalt mixed with sand or asphaltic concrete, to which is applied under pressure a layer of hot stones, gravel or the like 4, and a frame of longitudinal metallic bars 3 connected transversely by looped wires; over the bars may be provided a continuous wire winding 5, and the interstices between the stones, bars and wires are filled with fluid cement over which is applied an outer layer of cement mortar 6. Additional layers of the reinforced cement mortar, with or without interposed layers of asphalt, may be added. The hot stone &c. may be embedded in the asphalt tube by rolling the latter upon a layer of the stonv material, and the cement mortar may be applied to the desired thickness by rolling the tube thus far formed on to a layer of the mortar spread upon a linoleum or rubberized sheet 7. The completed tube is consolidated by a subsequent rolling. Fig. 3, shows a means for gauging the thickness of each layer during the various rolling operations. The core 1 receives at its ends interchangeable gauge rings 9 which roll on the platform 8. In a modified method adapted for constructing the pipe in a trench, longitudinal segments of the tube having the layerconstruction described, are formed in moulds 14, Fig. 5, the thickness of each layer being regulated by curved smoothing tools such as 16, which are slidden along the edges of the mould. For the asphalt layer, the tool may be heated electrically or otherwise. The segments are assembled between two circular frames 19, Fig. 6, mounted on standards 22 in the trench, one of the standards being adapted to be erected in the end of the preceding completed pipe section. The longitudinal joints between the segments are made by fillings of material corresponding with the contiguous material in the segments. The whole is then overlaid with wire 5 and the cement outer layer applied and consolidated by a roller 13. Instead of incorporating sand in the asphalt and cement, pumice powder may be used in the construction of tubes of light weight.

Abstract: 161,164. Dorr Co., (Assignees of Peck, C. L.). March 27, 1920, [Convention date]. Void [Published under Sect. 91 of the Act]. Plant; gravity-separation apparatus; aerating; bacteriological processes; manures. - Sewage is agitated or beaten to comminute the more nitrogenous solid matter, then strained and treated with activated sludge, air being introduced in such a manner that it causes circulation of the liquid. Fig. 2 shows a rotating strainer provided with a longitudinal baffle 17 which comminutes the more nitrogenous solids and lifts material which cannot pass through the strainer into a trough 19. From the interior of the strainer the liquid is passed into the lower compartment of a tank 22, Fig. 3, which is divided by a sloping annular tray or shelf 31. The bottom of the tank has air diffusers 24 comprising pipes arranged as the sides and diagonals of a square. Under the influence of the air the liquid rises into a central pipe 44 the major part of the liquid passing downwards again through a pipe 42, attached to a rotating shaft 84, which supports scrapers 38 directing sludge outward along the bottom of the tank to mingle with the in-flowing liquid. A portion of the circulating liquid flows over the top of the pipe 44 and is directed on to the tray 31 by a concentric baffle 46. Rotary scrapers are provided to coact with the surface of the tray. The liquid passes away by the launder 47 for further treatment in one or more similar tanks, while some of the sludge is returned to the lower compartment down wells 32. Sludge may also be drawn off through a pipe 48. A skimming-device 49 of involute form coacts with a stationary but partly flexible device 55 to direct fats or similar floating matter into a receptacle 56. To promote the growth of nitrogen-fixing organisms the sewage is maintained alkaline to a limited degree. The hydroxide of iron or other non-toxic metal or a compound from which such hydroxide is formed may be introduced into the liquid. Crenothrix and vorticella are organisms stated to increase the nitrogen content of the sludge or effluent. Reference is made to the use of sulphuric acid and phosphate rock in the production of fertilizer from the sludge. The solid matter separated by the strainer may be dried and incinerated or it may be ground and returned to the more liquid portion prior to the aeration treatment.
