Title: Improvements in apparatus for treating raw materials for the manufacture of cement
IPC: B04B5/12
Filed: 1933-12-19
Abstract: 430,430. Preparing raw materials for the manufacture of cement. JORGENSEN, M. VOGEL-, 24, Bulowsvej, Frederiksberg, near Copenhagen. Dec. 19, 1933, No. 35759. [Classes 59 and 82 (ii)] Raw materials for the manufacture of cement are passed direct from one or more wash mills, without intermediate grinding, to one or more sieve machines adapted to disintegrate the material and separate the fine from the coarse particles. Each sieve machine comprises a sieve which surrounds a rotor carrying blades which project outwards from the rotor, and force the material against the sieve, the shape and inclination of the blades and the speed of the rotor being so co-ordinated that the blades present advancing wall surfaces which receive all the material and distribute it substantially evenly in the axial direction of the sieve. The fine particles passing through the sieve may be passed direct to a cement kiln or to a container for the finished slurry or may first be passed through one or more further sieve machines. The coarse particles from the first sieve machine, after being passed if desired through one or more further sieve machines, may be returned to the wash mill or mills, or may be passed to a grinding mill and thence either back to the sieve machine or machines, or direct to the container for the finished slurry. The preferred type of sieve machine is shown in Figs. 4,..7 and consists of a container 15 within which is a stationary cylindrical sieve 6. The pulp is fed through an inlet 11 into a compartment 12 having a bottom 13 formed as a coarse sieve for retaining oversize particles. A rotor 7, partly conical and partly cylindrical, is mounted on a shaft 9 within the sieve 6 and carries blades 8 which project outwards from the rotor. To distribute the material evenly each blade comprises an upper and a lower wing, each of which as viewed edge-on slopes backwards relatively to the direction in which the blades are moving, the wings meeting on the line a-a<1>, where the material sliding down the conical part of the rotor first meets the blades. The backward inclination of the lower wing is less than that of the upper, and to prevent escape of material the tops and bottoms of the blades are bent forward. The blades are also curved or inclined backwards relatively to the radii of the rotor as shown in Fig. 5 to lessen the force of the impact of the blades on the material. As shown in Fig. 7, the blades with two wings may be replaced by two sets of blades, the sets 17, 18 corresponding respectively with the upper and lower wings of the blades 8. If desired either the blades 17 or the blades 18 and the corresponding part of the sieve may be omitted. Typical arrangements of plant for treating raw materials in cement manufacture and comprising wash mills and sieve machines with or without grinding mills are shown in Figs. 1...3 (not shown). Specification 2599/09, [Class 59], is referred to.

Title: Improvements in or relating to apparatus for inspecting a medium with supersonic waves
IPC: G01N29/38
Filed: 1946-12-09
Abstract: 641,081. Supersonic inspection devices. SPERRY PRODUCTS, Inc. Dec. 9, 1946, No. 36301. Convention date, Dec. 19, 1945. [Class 118 (ii)] In apparatus for investigating a medium by transmitting therein a pulse of supersonic frequency, and receiving and indicating the pulse reflections, means is provided for maintaining the receiver ineffective until the generation of a pulse ends. Preferably the receiver is ineffective immediately prior to the reception of the reflected pulse from the opposite surface of the medium so that defects &c. near the entering or rear boundaries of a medium can be clearly indicated. The apparatus can be employed in an aircraft for determining whether the aircraft is within a predetermined distance from the ground. As shown, a pulse from a generator 10 is impressed on a crystal 11, in engagement with a workpiece 12, and on an amplifier 15 which is connected to the vertical plates of an oscilloscope 16. The horizontal plates 17 are connected to a sweep circuit 19. In Fig. 2A, indications 25, 25<SP>1</SP> represent the transmitted and reflected pulse, and 26, 26<SP>1</SP> the reflections from defects D, D<SP>1</SP> in the work-piece 12 with a normal receiver. To obviate the merging of the indications when the defects are closer to the boundaries of the work-piece, the receiver is rendered effective from A to B, but ineffective from B to A, whereby only defects will be indicated. The generator 10 includes a synchronizer 30 comprising a discharge tube 31 arranged to be periodically discharged by a condenser 32 and battery 33, to pass a current through a phase inverter 35 to a discharge tube 37 to generate a pulse; the frequency is determined by a condenser 38 and coil 39. The voltage train applied to the crystal 11 is also supplied to the grid G of a valve 50 in the amplifier, but this valve cannot conduct since a larger negative voltage is impressed on a suppressor grid G<SP>1</SP> therein by a battery 51. The grid G<SP>1</SP> is controlled by a pulse generator 60 comprising a valve 61, normally conductive when a valve 62 is biassed to cut-off and non- conductive. The positive pulse generated by the valve 35 is fed to the grid 66 of the valve 62 through a time-delay circuit 68, 69, whereby sufficient positive voltage is not impressed on the grid 66 to render the valve 62 conductive until the generated pulse has ended. Then the valve 62 conducts and, through an amplifier valve 63, places a positive voltage on grid G<SP>1</SP> to allow the receiver amplifier 15 to receive signals occurring after the generated pulse has ended, i.e. from point A to point B. To maintain the generator effective from A to B when the generated pulse has ended, a condenser 71 and resistance 72 are provided. At point B, valve 62 becomes non-conductive and valve 61 conductive, the positive signal is removed from grid G<SP>1</SP>, and amplifier 15 is ineffective to register the reflected pulse from the rear boundary S<SP>1</SP> of the work-piece 12. Specification 641,095 is referred to.

On pulling out clean towelling, the previously used towelling 40c, which was lifted by a spring motor 125, 128, Fig. 6, on a roller 147 into a rear compartment 101, is pulled down over roller 152 to provide an adequate amount of towelling and maintained in its lowered position by a finger .149 on plate 135 carrying roller 147 engaging stop 92 on lever 89 which is moved into position by the end 87 of lever 65 when it is rotated to its stop position: When the suction cups part, spring 72 lifts lever 65 to release stop 92 whereupon the soiled towelling is lifted into the rear compartment 101 and the measuring roller freed for further dispensing. The last portion of towelling is retracted completely into the compartment until plate 135 abuts leaf spring 155 since no towel tension restricts movement of the spring motor 125, 128.
