Filed: 1943-09-06
Abstract: 577,422. Screw conveyers. STEVENS, A. H. (Steel Products Engineering Co.). Sept. 6, 1943, No. 14563. [Class 78(i)] In apparatus for feeding solid fuel from a storage bin to a furnace of the kind in which one worm extracts the fuel from the bin and another worm delivers it to the furnaces, the motor for driving the worms is mounted on a transfer chamber which receives the overlapping ends of the worms. The conveyer 12, Fig. 2, is arranged at.the bottom of the bin 10 and delivers the fuel to one side of a chamber 13, Fig. 3, on which is mounted the driving motor 69. The conveyer 14 which delivers the fuel to the furnace 11 is disposed at the other side of the chamber. A non-circular recess in the end of the worm shaft 15 is engaged by the similarly shaped end 31 of a short driving shaft 30 which is mounted in a housing 28 on the end wall 29 of the chamber. A sprocket 35 fast on the shaft 30 is disposed within an enlargement 34 of the housing which is closed by a removable plate 37. An end thrust bearing 36 is arranged between the sprocket and the housing 28. The conveyer 14 is connected similarly to a driving shaft 46, but the end thrust bearing 51 is supported by the cover plate 52. A reverse flight 56 on the end of the shaft 15 prevents packing of the fuel in the corner of the chamber and also assists the transfer of the fuel from one conveyer to the other. The sprockets 35, 50 are connected by chain gearing to sprockets 76, 82 on a shaft 75 which are enclosed by housings 74, 81, respectively, mounted on the tops of the housings 28, 45. The motor 69 is connected to the shaft 75 by a belt 70 and reduction gearing contained in the casing 68. The tube 60 enclosing the worm 14 may be made in sections 61 connected by clamps 62. A blower 88 driven by the motor supplies air to the tuyeres of the furnace through a duct 89. A clutch and change speed gearing member 91, Fig. 2, permits operation of the blower alone or the blower and conveyers together at predetermined desired speeds. The conveyer 14 either may have a greater capacity than the conveyer 12 or be driven at a higher speed in order to remove fuel from the chamber at a rate greater than that at which it is fed to it.

Title: Improvements in dish washing machines
IPC: A47L15/42
Filed: 1946-05-14
Abstract: 611,958. Dish-washing machines. WELLS, S. G. BURT-. May 14, 1946, No. 14563. [Class 138 (i)] In a dish-washing machine having a coinpartment to hold the dishes, into which hot water from a heated tank is projected from spray nozzles and from an electric motor-operated water impeller operating in a sump, and in which is provided a water inlet valve controlling the volume of hot water admitted and a drain valve to evacuate the used water, a fluidcontrolled mechanism connected with a pressure pump operated by the driving motor of the impeller maintains the pressure water supply control mechanism in operative relation while the motor is operating and automatically effects the shutting-off of the water supply if the motor drive ceases to function. Water heated in a supply tank by a thermostaticallycontrolled heater is supplied to the sprays through a pipe 21, inlet valve 20 and pipe 26, the valve 20 being self-closing. The motor drives through a gear-box the impeller in the sump and also a slow shaft 12 carrying a cam disc having cam plates 36, 37, which periodically open the valve 20 by means of a lever 32, link 33, bell-crank lever 27 pivoted at 28, and valve stem 25. A self-closing drain valve is also provided to empty the container, and is opened periodically by the rotation of a shaft 44 actuated by a lever 46 and cam plates 49, 50 on a second cam -disc on the shaft 12. The drain valve is normally held closed by a spring 51. A starter switch is arranged in the power supply lead to the water heater, thermostat and electric motor and in this circuit is arranged a micro switch D which is normally maintained closed by a spring arm 52 engaging a disc 53 on the shaft 12. On closing the starter switch the motor starts and cuts in the switch D. The cam plates 36, 37, 49, 50 are arranged so that the inlet valve is opened for a washing operation, whereafter the drain valve is opened, the inlet valve being opened a second time for rinsing, followed by a second draining. At the end of the 'cycle a notch 54 in the disc 53 engages the spring arm 52 to open the switch D and stop the motor. The motor also drives a pump which delivers oil from the gearbox through a pipe 7 to the bottom of a cylinder 8 having a loaded piston 10 and an outlet port 9 communicating with the gear-box. The piston is raised by the oil pressure and maintained at the level of the port 9. The piston has a stem 31 fixed to one end of the lever 32, which is'thereby held in a position such that the cam plates 36, 37 can actuate the valve 20. If the motor drive fails, the piston 10 drops and lowers the lever 32, whereby the inlet. valve is closed in order to avoid flooding of the container, and while the pump is inoperative the valve cannot be opened.

Title: Improvements in or relating to the production of polyamine/epoxide reaction products
IPC: C08G59/18
Filed: 1960-04-27
Abstract: Reaction products are prepared from poly-(aminomethyl)-benzenes containing at least three amino-hydrogen atoms and glycidyl compounds, in such proportions that at least 4 such hydrogen atoms are available per epoxy group.  The reaction products are used as secondary curing agents for polyepoxides.  The glycidyl compounds specified are glycidyl esters of carboxylic acids, polyglycidyl polyethers and glycidyl ethers.  When a polyglycidyl compound is used the poly-(aminomethyl)-benzene should have at least four amino-hydrogen atoms.  Any remaining nitrogen valencies are satisfied by alkyl and preferably methyl groups.  The glycidyl compound is added to an excess of the polyamine (there are preferably 4-25 amino hydrogen atoms available per epoxy group) and they are reacted at temperatures between 20 DEG  and 150 DEG C. Optional additives include accelerators, e.g. phenol, and triphenyl phosphite; fluxing agents, e.g. urea-formaldehyde resins, and solvents, e.g. butanol and toluene.  The reaction products are used to cure polyepoxides such as polyglycidyl polyethers.  Optional additives include fillers, e.g. glass fibres and coal tar; pigments, e.g. titanium dioxide, and solvents, e.g. dioctyl phthalate.  In a typical example, meta-xylylene diamine, a glycidyl polyether of bisphenol A, butyl glycidyl ether, triphenyl phosphite, a urea-formaldehyde resin, butanol and toluene are reacted by heating at 60 DEG C. for one hour with stirring.  The reaction product is mixed with a glycidyl polyether of bisphenol A containing butyl glycidyl ether to give a lacquer which is cured at room temperature.  In comparative examples the reaction product used in the lacquer is replaced meta-phenylene diamine, a cyclo-aliphatic polyamine, the reaction products of these amines with epoxides and metaxylylene diamine.ALSO:Reaction products are prepared from poly-(aminomethyl)-benzenes containing at least three amino-hydrogen atoms and glycidyl compounds, in such proportions that at least 4 such hydrogen atoms are available per epoxy group.
