Title: Process of and apparatus for drying material to be ground in revolving drums
IPC: F26B11/04
Filed: 1921-03-14
Abstract: 160,423. Fasting, J. S. March 22, 1920, [Convention date]. Gravity, materials descending by.-Relates to a process of and apparatus for drying materials to be ground in revolving drums, such as ball and tube mills, and consists in heating either the coarser portion of the material or the grinding bodies before placing them in the drums. Fig. 1 shows an apparatus for carrying out the invention in which the material is placed in a revolving sieve 4 so that the finer portion of the material falls into the shaft 3 and the coarser portion into the shaft 7 which may be integral with the shaft 3. The shaft 7 communicates with a fire-grate 11, the gases of which pass through the shaft to the chimney 13. The fire and the heated coarse material are carried by a conveyer 8 to the grinding - drum 1, the vapours from which escape through a flue 14. In a modification, the grinding bodies 2, Fig. 2, pass out of the drum and are heated before being returned with the material. The new material and the grinding bodies passing out of the drum are carried by the conveyer 25 to a sieve 26 from which they pass into the shafts 3 and 7 respectively. The grinding bodies are heated in the shaft 7 and fall with the material on to a rotating plate 27 and thence into the drum 1. The drum is formed with a partition 16 to which the outlet device 15 is secured. The material and the bodies pass through the outlet device on to a cylindrical sieve 18 which rotates with the drum. The material passes into the annular space 19 and is discharged from the drum by the shovels 20 attached to the end of the drum. The grinding bodies pass through the tube 23 into the shoot 24 from which they are carried by the conveyer 25 to the sieve.

Title: Production of esters of carboxylic acids
IPC: C07C69/04
Filed: 1943-05-21
Abstract: Esters of carboxylic acids are prepared by reacting alkyl halides having less than ten carbon atoms and containing at least one isolated halogen atom with an aliphatic carboxylic acid primary amide having less than seven carbon atoms, at a temperature above 100 DEG C.  An " isolated halogen atom " is defined as being a halogen atom attached to a carbon atom which is otherwise attached only to carbon or hydrogen atoms.  Aliphatic halides which may be used include ethyl chloride, butyl chloride, isobutyl chloride, the amyl chlorides, iso-octyl chloride, ethylene dichloride, and butylene chlorides.  It is preferred to use an aliphatic halide in which the isolated halogen atom is attached to a carbon atom having two hydrogen atoms attached thereto.  Amides of the following aliphatic carboxylic acids are specified: formic, acetic, isobutyric, caproic, vinyl acetic, crotonic and adipic acids.  At least two and, preferably, 5 to 20 molecular equivalents of the amide based on the halide should be used.  Temperatures from 100 DEG  to 300 DEG  C. may be employed, but the preferred range is 170 DEG  to 270 DEG  C.  Superatmospheric pressures may be employed.  In examples: (1) formamide is reacted with n-octyl chloride to yield n-octyl formate; (2) octyl chloride with acetamide to yield octyl acetate; (3) 1-1-1-5-tetrachlorpentane with formamide to yield the formate of 1-1-dichlorpentane-1-ol-5; (4) heptyl bromide and formamide are reacted to give n-heptyl formate.

Abstract: 138,224. Horne, A. E. April 2, 1919. Water-waste preventers; water supply for ranges.-A flushing system for ranges of water closets comprises a main tank a, a control tank c for supplying the cisterns y, and an automatic tank z delivering to the basins or drains. When one of the cisterns y is discharged, the water-level in the gravitation pipe w falls, and with it a float k, Fig. 2. A valve in a chamber n is then opened, water in the chambers n, c, is quickly discharged, and the float f falls. A cock d is then fully opened, and water passes from the tank a along a pipe v and branches x to the cisterns y. The cock d remains fully open until the cistern is filled. Then, all the cisterns being full, water flows back along the pipe w, and the valves are closed. A branch pipe s discharges through a nozzle t into the chamber m or the chamber e whenever the cock d is opened. It may have a branch u to discharge directly into the tank c. The water discharged into the tank c varies directly as the number of flushes and passes into the automatic tank z, the flushes given by which will also vary similarly in frequency.

Abstract: 807,961. Aerials; R.F. couplings. BELLING & LEE Ltd. April 12, 1957 [March 16, 1956], No. 8247/56. Class 40 (7). A wide-band aerial of reduced size compared with a simple element resonant at the same frequency comprises a cone-shaped element fed through an inductance. The aerial may be made effective in two separate frequency bands by forming the conical element 1 so that it is resonant in the higher frequency band and providing an inductive element 3 of such value that in combination with it the conical element is resonant in the lower frequency band. A coupling capacitor chosen so that at the higher frequency the series inductance-capacitance combination has substantially zero impedance is inserted between the inductor 3 and the feeder line 2. As shown, an unbalanced feeder with its other conductor 5 connected to a circular earth counterpoise 6 is used but a symmetrical aerial system including two conical elements and a balanced feeder is an alternative arrangement. The inductor may be in coil form or a short length of transmission line operating as an inductance. It is pointed out in connection with Fig. 2 (not shown) that the cone and counterpoise may respectively form the upper part and base of a vase for artificial flowers and the like, the inductor and capacitor being contained in a tubular stem of insulating material. An embodiment which may be used as a support for a flower vase or plant pot is shown in Fig. 3. In this embodiment a cone frustrum is formed by an array of conductive rods 10 which are taken through the top flange 13 of a bobbin 14 of insulating material and then bent to converge at the central connecting point 12. The bottom flange 15 of the bobbin supports a second array of rods 16 which support the structure and act as the electrical counterpoise. The inductor 3 and capacitor 4, together with the connections to the coaxial feeder 18, are located within the stem of the bobbin 14.

Abstract: 801,495. Electric correspondence control. ALLMANNA SVENSKA ELEKTRISKA AKTIEBOLAGET. March 20, 1956 [March 23, 1955], No. 8618/56. Class 40 (1). Means for indicating differences in rotational speeds comprises two alternating voltage tachometer generators 1, 2 which at zero speed difference provide alternating voltages of equal frequencies the alternating voltages being added and supplied to an indicating means consisting of a rectifier 7 followed by a smoothing filter 9, 10 which is so dimensioned that it cannot smooth frequencies substantially corresponding to the speed difference to be indicated and a relay means 11, which is arranged to react when the instantaneous value of the voltage from the smoothing filter falls below a predetermined value. As shown, the relay means comprises a thermionic valve 11 and this may have a relay connected in its anode circuit, the relay being arranged to control, for example, a mechanical coupling between a starting motor and a rotating load having a large inertia. In such a case one of the tachometer generators is driven by the starting motor and the other by the load. The outputs of the tachometer generators are applied to the rectifier 7 through equal resistances 3, 4. When the speed differences are large the output of the smoothing filter is a negative D.C. voltage which is sufficient to bias the valve 11 to cut-off, but as the frequency difference falls the filter output changes to varying D.C. and when the minimum instantaneous value of the D.C. voltage falls low enough the valve 11 is enabled to conduct and so operates the relay. A voltage source 14 can be connected between the capacitor 10 and the grid of the valve 11 to change its cut-off voltage. In a modification the generator outputs may be applied to the rectifier 7 through a transformer 7.
