Abstract: 654,537. Decarburizing iron castings. BIRLEC, Ltd., HANCOCK, P. F., and SCHULTE, F. W. K. July 28, 1948. No. 20092. [Class 72] [Also in Group XII] In a process of annealing carbon containing iron or iron alloy castings the charge of castings in a gas tight furnace is heated to 850-1000‹C at which temperature the carbon in the castings reacts with oxygen initially present in or supplied to the furnace to form Co and Co 2 , the products of combustion are circulated and the excess vented from the furnace, the vented products being burned in a steam generating plant at or below a predetermined efficiency and the steam produced, with or without air, is introduced into the furnace out of contact with the castings so that the process is self regulating in that the atmosphere is maintained decarburizing but non- oxidizing to the castings. The efficiency of the steam plant should not exceed 17 per cent and may be controlled by varying the supply of combustion air to the vented products. Air may be superimposed on the steam supply, the flow of air being less than the amount of steam it would be necessary to supply at the end of decarburizing if no air was superimposed. The apparatus, as shown, may comprise a furnace chamber a having heating elements f and a gas seal d. The excess products of the reaction are vented through a passage i, air for combustion being supplied through a pipe m controlled by a valve o. The heat of combustion generates steam in a boiler k, which steam, with or without air from a pipe n, is led through a pipe j into the furnace. A fan g circulates the atmosphere within the furnace.

Title: Production of organic phosphorus esters
Inventor: COATES HAROLD
IPC: C07F9/141
Filed: 1964-05-14
Abstract: Tris-2,3-dihaloalkyl phosphites are obtained by reacting a phosphorus trihalide e.g. phosphorus trichloride with at least 3, and preferably less than 4-5 molar proportions of a 2,3-dihaloalkan-1-ol in the substantial absence of a base.  The preferred reaction temperature is 20 DEG  C.-30 DEG  C.  The hydrogen halide produced in the reaction may be carried away by an inert gas such as nitrogen, and the residual hydrogen halide removed at the end of the reaction by the addition of a minor proportion of ammonia or of a tertiary amine. The reaction may be carried out continuously by mixing separate streams of phosphorus trihalide and dihaloalkanol in a first reaction zone and then removing the hydrogen halide in a second zone. Specified dihalo alkanols are 2,3-dibromopropanol, 2,3 - dichloropropanol, 2,3 - difluoropropanol, 2,3 - di - iodopropanol, 2,3 - chlorobromopropanols, 2,3 - bromofluoropropanols, and 2,3-dibromobutanol. Diluents such as hydrocarbons and chlorinated hydrocarbons may be used to moderate the reaction.  The products may be oxidized to the corresponding phosphates by such reagents as hydrogen peroxide in the presence of a base, air or oxygen in the presence of a free radical producing catalyst or in the presence of ultra-violet radiation, by various organic peroxides, hydroperoxides, and peracids.  The phosphite products may be used as stabilizers or antioxidants for polymeric materials, and the phosphates as flameproofing agents for polymers such as polyethylene, polystyrene, and polyurethanes, particularly for the cellular forms of polystyrene and polyurethanes.

Abstract: 514,982. Filters. FILTRATION EQUIPMENT CORPORATION. July 8, 1938, No. 20267. Cbnvention date, July 9, 1937. [Class 46] In apparatus for cleaning sand filters of the type in which a cleaning chamber is moved over successive sections of the bed, the sand below the chamber being agitated and the impurities carried from the chamber by wash water, the end walls of the chamber are provided with sealing means which project downwardly into the sand but do not push the sand forward when the chamber is advanced. As shown in Figs. 1 and 2, the chamber is formed by side walls 2 and transverse partitions 3, 4, supported from a carriage 17 movable longitudinally over the filter on rails 19, the wheels 18 being driven by an electric motor through reduction gearing 21. The starting switch of the motor may be controlled by a float in the influent channel of the filter. The position 3 terminates in a levelling apron 12 and the partition 4 has a horizontal extension 6 terminating in a vertical baffle 7. The baffle 7 divides the chamber into compartments, one containing an agitator 15 and the other a centrifugal pump 24 which delivers the wash water containing impurities from the sand through a pipe 27 to a discharge launder 30. Rollers 51 mounted in bearings which can slide vertically in extensions of the walls 2 press on the upper surface of the filter bed 16 to form a seal in front of and behind the chamber. To aid the sealing effect of the rollers, the latter are provided with vanes or projections 61 which enter the sand of the bed. The spaces between the ends of the rollers and the extensions of the walls are sealed by means of wipers 62 of packing or resilient material, such as bronze, welded to the extensions. To seal the sides of the chamber the walls 2 have extensions 50 which project into the sand. In this apparatus the liquid under treatment is supplied to an inlet channel 31 and after passing downward through the filter bed is discharged over a weir 39. The filter bed is formed of magnetite sand and the agitator 15 is an electromagnet or solenoid. In. the apparatus shown in Fig. 4, the rollers 51 are mounted on rails 70 which form side walls for the filter bed., Leakage between the ends of the' rollers and the side walls 72 of the cleaning chamber is prevented by circular wipers welded to the ends of the rollers. The longitudinal seals are formed by extensions 74 of resilient material welded or rjveted to the walls 72 and pressing against the outside of the rails 70. As, shown in Fig. 5, longitudinal seals are formed by resilient flanges 80 fixed to the walls 2 and pressing at their outer edges on blocks or rails 83 at the sides of the filter bed.

Abstract: 799,135. Date-indicators. KAUFMAN, S. J. June 29, 1956, No. 20285/56. Class 106 (4). A date-indicator is incorporated in an alarm time-piece with a main rocking lever L, including a projection 30 for advancing a ratchetwheel 17 rigid with a date disc 18, while a cam follower 39 co-operating with a spiral-shaped cam 13 provided with a radial step and revolving at a speed of one revolution per twentyfour hours is connected elastically with the lever L, which is urged by a return spring 35 into a position producing sudden progression of the projection 30 at the moment of the dropping of the cam follower 39 along the cam step to advance the rate one unit. The lever L and follower 39 are mounted on the same pivot pin 24, a pin 40 of the follower engaging a slot 41 in the lever, while an elastic tongue 37 mounted on the lever L urges the follower 39 into contact with the cam 13 which, as it turns in the direction F1 urges lever L and follower 39 in the direction F2, shifting in the direction F3, the projection 30, which forms part of a rocking member 32, pivoted to the lever L and providing anchorage for the return spring 35. As soon as the follower 39 drops down the step of the cam 13, the projection 30 acts, through a slot 31 in a plate 2, on the ratchetwheel 17, return movement being prevented by a spring-urged detent 22. The ratchetwheel 17 has thirty-one teeth so that adjustment is required at the end of short months by hand through a knob 29 whereby a pin straddled by a fork 26 rigid with the lever L can be made to move the lever first in the direction F2 and then in the reverse direction simulating, the normal date advance movement and due to the elastic connection between the follower 39 and lever L, the cam 13 will not prevent such movement.

Strip material S is passed through a micrometer gauge 10, a pin hole detector 11 and a shear cutter 12 where it is cut into sheets 15 and delivered to a conveyer 24 moving at a high speed sufficient to separate the sheets. Sheets rejected by the gauge 10 and detector 11 are deflected in known manner to a conveyer 28 moving at the same speed as conveyer 24, while the other sheets are passed to a conveyer 29, also moving at the same speed as conveyer 24. Sheets with defective surfaces are deflected on to a further fast moving conveyer 33, while prime sheets are passed at the same speed to the conveyer 32. A photo-electric cell causes operation of the deflector 36 each time a sheet is moved so that the prime sheets are alternately deflected to the conveyers 39 and 42 which run at half the speed of the conveyer 32. These conveyers deliver the sheets in shingled fashion on to slow-moving conveyers 41, 45 respectively for delivery to two piles 21, 20. The conveyers 28 and 33 pass the rejected sheets to two similar deflector arrangements 4 and 57 for delivery to four piles 16, 17 and 18, 19 respectively. Instead of the mechanically operated pivoted deflectors 36, 47 and 57 fixed deflectors may be employed, the sheets being alternately passed above and below the deflectors by the action of preceding upper and lower rolls embodying electromagnets alternately energized. Specifications 690,344 and 703,998 are referred to.
